Effects of functional status changes before and during hospitalization on nursing home admission of older adults

Interventions to Promote Physical Activity and Reduce Functional Decline in Medical Inpatients: An Umbrella Review

OBJECTIVES

Physical inactivity in hospitals is common and is associated with poor patient and clinical outcomes. This review was undertaken to identify and describe the effectiveness of interventions implemented at the ward or system level for improving physical activity and reducing functional decline in general medical inpatients. The secondary aim was to describe the effects on length of stay, discharge destination, falls, and hospital costs.

DESIGN

Umbrella review.

SETTING AND PARTICIPANTS

Systematic reviews that evaluated ward- or system-level interventions aiming to improve physical activity or reduce functional decline in medical inpatients.

METHODS

PubMed, EMBASE, Cochrane Database, CINAHL, JBI, and Web of Science databases were searched for English-language reviews published between 2000 and 2023. AMSTAR 2 was used to assess methodologic quality. Two reviewers independently assessed eligibility and methodologic quality and completed data abstraction, with results presented as a narrative synthesis.

RESULTS

The search yielded 568 systematic reviews of which 12 met criteria, half of which were published since 2020. Reviews included 76 unique primary studies with 72,645 participants. Most reviews were of low quality. Interventions that focused on progressive mobilization likely increased physical activity participation, reduced functional decline, and improved discharge home. Multicomponent interventions that employed multiple strategies targeting a broader range of barriers likely improved functional decline and discharge home and may have been associated with shorter length of stay. No interventions were associated with increased frequency of falls. Few studies reported costs.

CONCLUSIONS AND IMPLICATIONS

Progressive mobilization interventions and multicomponent interventions appear to be effective for improving physical activity participation and reducing functional decline in medical inpatients. Further high-quality studies may help to determine the most important aspects of multicomponent interventions. Standardized terminology related to inpatient physical activity may help promote a shared understanding and purpose across professions.

Exercise Intervention and Hospital-Associated Disability: A Nonrandomized Controlled Clinical Trial

Importance

Inpatient exercise interventions may prevent, at least partly, hospital-associated disability (HAD) in older adults, but whether they also confer clinical benefits in the months following discharge is unclear.

Objective

To examine the association of exercise and health education with HAD incidence in hospitalized older adults receiving acute hospital care at discharge and 3 months later.

Design, Setting, and Participants

This single-center open-label, nonrandomized controlled clinical trial included patients aged 75 years or older seen at an acute care for elders unit at a tertiary public hospital in Madrid, Spain, from May 1, 2018, to June 30, 2022.

Interventions

Patients were allocated to an intervention or control group. Both groups received usual care, but the intervention group also performed a supervised multicomponent exercise program (daily strength, balance, and walking exercises along with inspiratory muscle training) during hospitalization and received health education on how to exercise at home and telephone counseling during follow-up.

Main Outcomes and Measures

The primary outcome was HAD incidence (determined by the Katz Index of Independence in Activities of Daily Living [hereafter, Katz Index]) at discharge and after 3 months compared with baseline (ie, 2 weeks before admission). Secondary outcomes included HAD incidence determined by the Barthel Index for Activities of Daily Living, ambulatory capacity decline at discharge and follow-up, changes in physical performance at discharge, and incidence of falls, readmissions, and mortality during the follow-up period.

Results

The study included 260 patients (134 women [51.5%]; mean [SD] age, 87.4 [4.9] years [range, 75-105 years]; median hospital length of stay, 7 days [IQR, 5-10 days]), of whom 130 received the intervention and 130 were in the control group. Differences in HAD incidence did not reach statistical significance at discharge (odds ratio [OR], 0.62; 95% CI, 0.37-1.05; P = .08) or follow-up (OR, 0.65; 95% CI, 0.36-1.17; P = .15) when using the Katz Index. A lower HAD incidence was observed in the intervention group at discharge (OR, 0.47; 95% CI, 0.27-0.81; P = .01) and at follow-up (OR, 0.36; 95% CI, 0.20-0.66; P = .001) when using the Barthel Index for Activities of Daily Living. The intervention was also associated with a lesser decline in ambulatory capacity (OR, 0.55; 95% CI, 0.32-0.96; P = .03) and improved physical performance at discharge (Cohen d, 0.39; 95% CI, 0.12-0.65; P = .004). No significant associations were observed for readmissions, falls, or mortality.

Conclusions and Relevance

In this nonrandomized controlled clinical trial, an exercise and health education intervention was not significantly associated with reduced HAD incidence when measured by the Katz Index. However, the benefits found for several secondary outcomes might support the implementation of in-hospital exercise programs for older patients.

Functional Decline in Long-Term Care Homes in the First Wave of the COVID-19 Pandemic: A Population-based Longitudinal Study in Five Canadian Provinces

OBJECTIVE

We aimed to examine whether functional decline accelerated during the first wave of the COVID-19 pandemic (March to June 2020) for persons in long-term care facilities (LTCs) in Canada compared with the pre-pandemic period.

DESIGN

We conducted a population-based longitudinal study of persons receiving care in LTC homes in 5 Canadian provinces before and during the COVID-19 pandemic.

SETTING AND PARTICIPANTS

Residents in 1326 LTC homes within the Canadian provinces of Alberta, British Columbia, Manitoba, Newfoundland & Labrador, and Ontario between January 31, 2019, and June 30, 2020, with activities of daily living Hierarchy scale less than 6 and so, who still have potential for decline (6 being the worst of the 0-6 scale).

METHODS

We fit a generalized estimating equation model with adjustment for repeated measures to obtain the adjusted odds of functional decline between COVID period exposed and unexposed pre-pandemic residents.

RESULTS

LTC residents experienced slightly higher rates of functional decline during the first wave of the COVD-19 pandemic compared with the pre-pandemic period (23.3% vs 22.3%; P < .0001). The adjusted odds of functional decline were slightly greater during the pandemic (odds ratio [OR], 1.17; 95% CI, 1.15-1.20). Likewise, residents receiving care in large homes (OR, 1.20; 95% CI, 1.17-1.24) and urban-located LTC homes (OR, 1.20; 95% CI, 1.17-1.23), were more likely to experience functional decline during the COVID-19 pandemic. The odds of functional decline were also only significantly higher during the pandemic for LTC home residents in British Columbia (OR, 1.17; 95% CI, 1.11-1.23) and Ontario (OR, 1.25; 95% CI, 1.21-1.29).

CONCLUSIONS AND IMPLICATIONS

This study provides evidence that the odds of experiencing functional decline were somewhat greater during the first wave of the COVID-19 pandemic. It highlights the need to maintain physical activity and improve nutrition among older adults during periods of stress. The information would be helpful to health administrators and decision-makers seeking to understand how the COVID-19 pandemic and associated public health measures affected LTC residents' health outcomes.

"Inspiratory muscle weakness in acutely hospitalized patients 75 years and over": a secondary analysis of a randomized controlled trial on the effectiveness of multicomponent exercise and inspiratory muscle training

PURPOSE

The impact of hospitalization for acute illness on inspiratory muscle strength in oldest-old patients is largely unknown, as are the potential benefits of exercise and inspiratory muscle training (IMT) during in-hospital stay.

DESIGN AND METHODS

This was a sub-study of a randomized clinical trial that evaluated the efficiency of a multicomponent exercise program in preventing hospitalization-associated disability. Patients were randomized into control (CG) and intervention (IG) groups. The intervention included two daily sessions of supervised walking, squat, balance, and IMT. Baseline and discharge maximal inspiratory pressure (MIP) and inspiratory muscle weakness (IMW) were determined. The effect of the intervention on inspiratory muscle strength was assessed by analyzing (1) the differences between groups in baseline and discharge MIP and IMW, (2) the association, patient by patient, between baseline and discharge MIP, and the improvement index (MIP discharge/baseline) in patients with or without IMW.

RESULTS

In total, 174 patients were assessed (mean age of 87), 57 in CG and 117 in IG. Baseline MIP was lower than predicted in both sexes (women 29.7 vs 44.3; men 36.7 vs 62.5 cmH2O, P < 0.001, baseline vs predicted, respectively). More than 65% of patients showed IMW at admission. In women in IG, the mean MIP was higher at discharge than at admission (P = 0.003) and was the only variable that reached expected reference levels at discharge (Measured MIP 39.2 vs predicted MIP 45 cmH2O, P = 0.883). Patients with IMW on admission showed a statistically significant improvement in MIP after the intervention.

CONCLUSION

IMW is very prevalent in oldest-old hospitalized with acute illness. Patients might benefit from a multicomponent exercise program including IMT, even during short-stay hospitalization.

Association between Hospital-acquired Disability and Clinical Outcomes in Older Patients Who Underwent Cardiac Surgical

OBJECTIVE

This study aimed to clarify the association between hospital-acquired disability (HAD) and prognosis in older patients who underwent cardiac surgery.

METHODS

This single-center, retrospective, observational study included 141 patients aged ≥65 years who underwent cardiac surgery at our hospital from November 2016 to August 2021. The primary endpoint of this study was the occurrence of major adverse cardiac and cerebrovascular events (MACCEs) within 2 years of hospital discharge. HAD was defined as a score of ≤5 on any one of the functional independence measure (FIM) subitems at discharge compared to preoperatively.

RESULTS

MACCE was observed in 16.3%, and the incidence of MACCE was significantly higher in the HAD group than that in the non-HAD group (12.1 vs. 34.5%, log-rank, p = 0.003). HAD was also significantly associated with the MACCE (hazard ratio [HD]: 2.575, 95% confidence interval [CI]: 1.001-9.655, p = 0.046). The incidence rate of HAD was 20.6%, with age (odds ratio [OR]: 1.260, 95% CI: 1.080-1.470, p = 0.004), preoperative short physical performance battery (SPPB) score (OR: 0.462, 95% CI: 0.301-0.708, p <0.001), and postoperative delirium (OR: 6.660, 95% CI: 1.480-30.000, p = 0.014) identified as significant factors.

CONCLUSION

HAD is an independent predictor of MACCE in older patients who underwent cardiac surgery.

Assessment tools and incidence of hospital-associated disability in older adults: a rapid systematic review

Background

During hospitalization older adults have a high risk of developing functional impairments unrelated to the reasons for their admission. This is termed hospital-associated disability (HAD). This systematic review aimed to assess the incidence of HAD in older adults admitted to acute care with two outcomes: firstly in at least one activity of daily living from a set of functional tasks (e.g., Katz Index) and secondly the incidence of functional decline in an individual functional task (e.g., bathing), and to identify any tools or functional tasks used to assess activities of daily living (ADL) in hospitalized older patients.

Methods

A rapid systematic review was performed according to the recommendations of the Cochrane Rapid Reviews Methods Group and reported the data according the PRISMA statement. A literature search was performed in Medline (via Ovid), EMBASE, and Cochrane Central Register of Controlled Trials databases on 26 August 2021. Inclusion criteria: older adults (≥65 years), assessment of individual items of activities of daily living at baseline and discharge. Exclusion criterion: studies investigating a specific condition that could affect functional decline and studies that primarily examined a population with cognitive impairment. The protocol was registered on OSF registries (https://osf.io/9jez4/) identifier: DOI 10.17605/OSF.IO/9JEZ4.

Results

Ten studies were included in the final review. Incidence of HAD (overall score) was 37% (95% CI 0.30-0.43). Insufficient data prevented meta-analysis of the individual items. One study provided sufficient data to calculate incidence, with the following values for patients' self-reported dependencies: 32% for bathing, 27% for dressing, 27% for toileting, 30% for eating and 27% for transferring. The proxy reported the following values for patients' dependencies: 70% for bathing, 66% for dressing, 70% for toileting, 61% for eating and 59% for transferring. The review identified four assessment tools, two sets of tasks, and individual items assessing activities of daily living in such patients.

Conclusions

Incidence of hospital-associated disability in older patients might be overestimated, due to the combination of disease-related disability and hospital-associated disability. The tools used to assess these patients presented some limitations. These results should be interpreted with caution as only one study reported adequate information to assess the HAD incidence. At the item level, the latter was higher when disability was reported by the proxies than when it was reported by patients. This review highlights the lack of systematic reporting of data used to calculate HAD incidence. The methodological quality and the risk of bias in the included studies raised some concerns.

A single bout of prior resistance exercise attenuates muscle atrophy and declines in myofibrillar protein synthesis during bed-rest in older men

Impairments in myofibrillar protein synthesis (MyoPS) during bed rest accelerate skeletal muscle loss in older adults, increasing the risk of adverse secondary health outcomes. We investigated the effect of prior resistance exercise (RE) on MyoPS and muscle morphology during a disuse event in 10 healthy older men (65-80 years). Participants completed a single bout of unilateral leg RE the evening prior to 5 days of in-patient bed-rest. Quadriceps cross-sectional area (CSA) was determined prior to and following bed-rest. Serial muscle biopsies and dual stable isotope tracers were used to determine rates of integrated MyoPS (iMyoPS) over a 7 day habitual 'free-living' phase and the bed-rest phase, and rates of acute postabsorptive and postprandial MyoPS (aMyoPS) at the end of bed rest. Quadriceps CSA at 40%, 60% and 80% of muscle length significantly decreased in exercised (EX) and non-exercised control (CTL) legs with bed-rest. The decline in quadriceps CSA at 40% and 60% of muscle length was attenuated in EX compared with CTL. During bed-rest, iMyoPS rates decreased from habitual values in CTL, but not EX, and were significantly different between legs. Postprandial aMyoPS rates increased above postabsorptive values in EX only. The change in iMyoPS over bed-rest correlated with the change in quadriceps CSA in CTL, but not EX. A single bout of RE attenuated the decline in iMyoPS rates and quadriceps atrophy with 5 days of bed-rest in older men. Further work is required to understand the functional and clinical implications of prior RE in older patient populations. KEY POINTS: Age-related skeletal muscle deterioration, linked to numerous adverse health outcomes, is driven by impairments in muscle protein synthesis that are accelerated during periods of disuse. Resistance exercise can stimulate muscle protein synthesis over several days of recovery and therefore could counteract impairments in this process that occur in the early phase of disuse. In the present study, we demonstrate that the decline in myofibrillar protein synthesis and muscle atrophy over 5 days of bed-rest in older men was attenuated by a single bout of unilateral resistance exercise performed the evening prior to bed-rest. These findings suggest that concise resistance exercise intervention holds the potential to support muscle mass retention in older individuals during short-term disuse, with implications for delaying sarcopenia progression in ageing populations.

Recent functional decline and outpatient follow-up after hospital discharge: a cohort study

BACKGROUND

Functional decline is common following acute hospitalization and is associated with hospital readmission, institutionalization, and mortality. People with functional decline may have difficulty accessing post-discharge medical care, even though early physician follow-up has the potential to prevent poor outcomes and is integral to high-quality transitional care. We sought to determine whether recent functional decline was associated with lower rates of post-discharge physician follow-up, and whether this association changed during the COVID-19 pandemic, given that both functional decline and COVID-19 may affect access to post-discharge care.

METHOD

We conducted a retrospective cohort study using health administrative data from Ontario, Canada. We included patients over 65 who were discharged from an acute care facility during March 1st, 2019 - January 31st, 2020 (pre-COVID-19 period), and March 1st, 2020 - January 31st, 2021 (COVID-19 period), and who were assessed for home care while in hospital. Patients with and without functional decline were compared. Our primary outcome was any physician follow-up visit within 7 days of discharge. We used propensity score weighting to compare outcomes between those with and without functional decline.

RESULTS

Our study included 21,771 (pre-COVID) and 17,248 (COVID) hospitalized patients, of whom 15,637 (71.8%) and 12,965 (75.2%) had recent functional decline. Pre-COVID, there was no difference in physician follow-up within 7 days of discharge (Functional decline 45.0% vs. No functional decline 44.0%; RR = 1.02, 95% CI 0.98-1.06). These results did not change in the COVID-19 period (Functional decline 51.1% vs. No functional decline 49.4%; RR = 1.03, 95% CI 0.99-1.08, Z-test for interaction p = 0.72). In the COVID-19 cohort, functional decline was associated with having a 7-day physician virtual visit (RR 1.15; 95% CI 1.08-1.24) and a 7-day physician home visit (RR 1.64; 95% CI 1.10-2.43).

CONCLUSIONS

Functional decline was not associated with reduced 7-day post-discharge physician follow-up in either the pre-COVID-19 or COVID-19 periods. In the COVID-19 period, functional decline was positively associated with 7-day virtual and home-visit follow-up.

Physical activity is low before and during hospitalisation: A secondary observational study in older Australian general medical patients

OBJECTIVES

To quantify physical activity in patients prior to and during an acute general medical hospital admission and explore relationships between mobility, pre- and in-hospital physical activity.

METHODS

This was a prospective, single-site secondary observational study conducted on general medical wards at a tertiary hospital. Prehospital physical activity was measured via the Physical Activity Scale for the Elderly (PASE; scored 0-400); in-hospital physical activity was measured via accelerometry (time at metabolic equivalents [METs] > 1.5), and mobility was measured via the de Morton Mobility Index (DEMMI). Associations were determined via Spearman's correlations.

RESULTS

Forty-six participants were included: median age 81 [76-85] years, 59% female, DEMMI on admission 39 [30-49]. Prehospital physical activity was low (PASE median 27.1 [1.6-61.9]). In-hospital physical activity was also low (0.5 [0.2-1.5] hours per day being physically active and 54 [16-194] steps per day taken). No statistically significant relationships existed between pre- and in-hospital physical activity (Spearman's rho (ρ) 0.24, 95% CI -0.08-0.53, p = 0.07). However, physical activity levels in the pre- and in-hospital settings were positively associated with patients' mobility in-hospital (Spearman's ρ 0.44, 95% CI 0.15-0.67, p = 0.002; Spearman's ρ 0.40, 95% CI 0.08-0.645, p = 0.011 respectively).

CONCLUSIONS

Physical activity is low both before and during a general medical admission. Assessment of usual physical activity patterns should be part of the clinical assessment of patients in general medicine; however, the low activity levels observed indicate a need for valid and reliable tools suitable for an older, frail cohort. Findings will inform the development of physical activity guidelines during hospitalisation.

A protocol for randomized controlled trial on multidisciplinary interventions for mobility limitation in the older adults (M-MobiLE)

BACKGROUND

Mobility limitation-the loss of exercise capacity or independent living ability-is a common geriatric syndrome in older adults. As a potentially reversible precursor to disability, mobility limitation is influenced by various factors. Moreover, its complex physiological mechanism hinders good therapeutic outcomes with a single-factor intervention. Most hospitals have not incorporated the diagnosis and evaluation of mobility limitation into medical routines nor developed a multidisciplinary team (MDT) treatment plan. We aim to conduct a clinical trial titled "A Multidisciplinary-team approach for management of Mobility Limitation in Elderly (M-MobiLE)" to explore the effect of the MDT decision-making intervention for mobility limitation.

METHODS

The M-MobiLE study will be a multicenter, randomized, and controlled trial. We will recruit a minimum of 66 older inpatients with mobility limitation from at least five hospitals. Older patients with mobility limitation admitted to the geriatrics department will be included. Short-Physical Performance Battery (SPPB), Activities of Daily Living (ADL), Function Impairment Screening Tool (FIST), Geriatric Depression Scale (GDS-15), Short Form - 12 (SF-12), Fried frailty phenotype, social frailty, Morse Fall Risk Scale, SARC-CalF, Mini-Mental State Examination (MMSE), Mini-Nutritional Assessment Short-Form (MNA-SF), and intrinsic capacity will be assessed. The intervention group will receive an exercise-centered individualized MDT treatment, including exercise, educational, nutritional, medical, and comorbidity interventions; the control group will receive standard medical treatment. The primary outcome is the change in the SPPB score, and the secondary outcomes include increased SF-12, ADL, FIST, MMSE, MNA-SF, and intrinsic capacity scores and decreased GDS-15 and SARC-CalF scores.

CONCLUSION

Our results will help develop a multidisciplinary decision-making clinical pathway for inpatients with mobility limitation, which can be used to identify patients with mobility limitation more effectively, improve mobility, and reduce the risk of falls, frailty, and death in older inpatients. The implementation of this MDT strategy may standardize the treatment of mobility limitation, reduce adverse prognosis, and improve quality of life.

Exploring the Frailty Components Related to Hospitalization-Associated Disability in Older Patients After Cardiac Surgery Using a Comprehensive Frailty Assessment

BACKGROUND

We investigated the components of frailty associated with hospitalization-associated disability (HAD) after cardiac surgery.Methods and Results: This retrospective, observational study evaluated 1,446 older patients after elective cardiac surgery at the Sakakibara Heart Institute. We examined the association between HAD and 7 domains of frailty assessed by the Kihon Checklist. HAD was defined as a decline in the ability to perform activities of daily living (ADL) between admission and discharge, as assessed by the Barthel Index. Logistic regression and decision tree analysis were used to identify associations between the number and type of frailty components and HAD. Of the 1,446 patients, 190 were excluded, and 90 (7%) developed HAD. An increase in the number of frailty components was a risk factor for HAD (odds ratio: 1.88, 95% confidence interval: 1.62-2.17). Decision tree analysis identified physical functional decline, depression, and cognitive dysfunction as factors associated with HAD. The incidence of HAD was highest in cases of physical functional decline (21%) and lowest for cases in which the 3 aforementioned factors were absent (2.8%).

CONCLUSIONS

An increased number of frailty factors increased the risk of HAD and the findings also reaffirmed the importance of a comprehensive assessment to evaluate the risk of HAD, including evaluation of physical function, cognitive function, and depression.

Association of Fragmented Readmissions and Electronic Information Sharing With Discharge Destination Among Older Adults

Importance

When an older adult is hospitalized, where they are discharged is of utmost importance. Fragmented readmissions, defined as readmissions to a different hospital than a patient was previously discharged from, may increase the risk of a nonhome discharge for older adults. However, this risk may be mitigated via electronic information exchange between the admission and readmission hospitals.

Objective

To determine the association of fragmented hospital readmissions and electronic information sharing with discharge destination among Medicare beneficiaries.

Design, Setting, and Participants

This cohort study retrospectively examined data from Medicare beneficiaries hospitalized for acute myocardial infarction, congestive heart failure, chronic obstructive pulmonary disease, syncope, urinary tract infection, dehydration, or behavioral issues in 2018 and their 30-day readmission for any reason. The data analysis was completed between November 1, 2021, and October 31, 2022.

Exposures

Same hospital vs fragmented readmissions and presence of the same health information exchange (HIE) at the admission and readmission hospitals vs no information shared between the admission and readmission hospitals.

Main Outcomes and Measures

The main outcome was discharge destination following the readmission, including home, home with home health, skilled nursing facility (SNF), hospice, leaving against medical advice, or dying. Outcomes were examined for beneficiaries with and without Alzheimer disease using logistic regressions.

Results

The cohort included 275 189 admission-readmission pairs, representing 268 768 unique patients (mean [SD] age, 78.9 [9.0] years; 54.1% female and 45.9% male; 12.2% Black, 82.1% White, and 5.7% other race and ethnicity). Of the 31.6% fragmented readmissions in the cohort, 14.3% occurred at hospitals that shared an HIE with the admission hospital. Beneficiaries with same hospital/nonfragmented readmissions tended to be older (mean [SD] age, 78.9 [9.0] vs 77.9 [8.8] for fragmented with same HIE and 78.3 [8.7] years for fragmented without HIE; P < .001). Fragmented readmissions were associated with 10% higher odds of discharge to an SNF (adjusted odds ratio [AOR], 1.10; 95% CI, 1.07-1.12) and 22% lower odds of discharge home with home health (AOR, 0.78; 95% CI, 0.76-0.80) compared with same hospital/nonfragmented readmissions. When the admission and readmission hospital shared an HIE, beneficiaries had 9% to 15% higher odds of discharge home with home health (patients without Alzheimer disease: AOR, 1.09 [95% CI, 1.04-1.16]; patients with Alzheimer disease: AOR, 1.15 [95% CI, 1.01-1.32]) compared with fragmented readmissions where information sharing was not available.

Conclusions and Relevance

In this cohort study of Medicare beneficiaries with 30-day readmissions, whether a readmission is fragmented was associated with discharge destination. Among fragmented readmissions, shared HIE across admission and readmission hospitals was associated with higher odds of discharge home with home health. Efforts to study the utility of HIE for care coordination for older adults should be pursued.

Implementation, Feasibility, and Acceptability of MATCH to Prevent Iatrogenic Disability in Hospitalized Older Adults: A Question of Geriatric Care Program?

Senior adults (>age 65) represent almost 20% of the population but account for 48% of hospital bed occupancy. In older adults, hospitalization often results in functional decline (i.e., iatrogenic disability) and, consequently, the loss of autonomy. Physical activity (PA) has been shown to counteract these declines effectively. Nevertheless, PA is not implemented in standard clinical practice. We previously showed that MATCH, a pragmatic, specific, adapted, and unsupervised PA program, was feasible and acceptable in a geriatric assessment unit (GAU) and a COVID-19 geriatric unit. This feasibility study aims to confirm that this tool could be implemented in other geriatric care programs, notably a geriatric rehabilitation unit (GRU) and a post-acute care unit (PACU), in order to reach the maximum number of older patients. Eligibility and consent were assessed by the physician for all the patients admitted to the three units (GAU, GRU, and PACU). The rehabilitation therapist taught each participant one of the five PA programs based on their mobility score on the decisional tree. Implementation (eligibility (%): patients eligible/number admitted and delay of implementation: number of days until prescription); feasibility (adherence (%): number sessions completed/number sessions prescribed and walking time (%): total walking time/time prescribed time); and acceptability (healthcare team (%): tool adequacy (yes/no) and patient: System Usability Scale questionnaire (SUS: x/100)) were evaluated and analyzed using a Kruskal-Wallis ANOVA or Fisher's exact test. Eligibility was different between the units (GRU = 32.5% vs. PACU = 26.6% vs. GAU = 56.0%; p < 0.001), but the time before implementation was similar (days: GRU = 5.91 vs. PACU = 5.88 vs. GAU = 4.78; p > 0.05). PA adherence (GRU = 83.5% vs. PACU = 71.9% vs. GAU = 74.3%) and walking time (100% in all units) were similar (p > 0.05). Patients (SUS: GRU = 74.6 vs. PACU = 77.2 vs. GAU = 77.2; p > 0.05) and clinicians (adequacy (yes; %): GRU = 78.3%; PACU = 76.0%; GAU = 72.2%; p > 0.05) found MATCH acceptable. Overall, MATCH was implementable, feasible, and acceptable in a GAU, GRU, and PACU. Randomized controlled trials are needed to confirm our results and evaluate the health benefits of MATCH compared with usual care.

Medication optimization according to the Fit fOR The Aged (FORTA) rules improves functional status in patients hospitalized for geriatric rehabilitation

INTRODUCTION

Functional status is one of the most important issues of geriatric care. Polypharmacy seems to be a modifiable factor associated with functional decline in older adults. However, the impact of pharmacotherapy optimization on the activities of daily living in patients undergoing geriatric rehabilitation has not been investigated prospectively so far.

METHODS

This post hoc analysis of a subsample of the VALFORTA study included individuals only undergoing geriatric rehabilitation with a length of in-hospital stay of at least 14 days. Medication was modified according to the FORTA rules in the intervention group while in the control group standard drug treatment was applied. Both groups received comprehensive geriatric treatment.

RESULTS

The intervention and control groups consisted of 96 and 93 individuals respectively. They did not differ according to basic data except for age and Charlson Comorbidity Index (CCI) on admission. On discharge, activities of daily living (Barthel index, BI) were improved in both groups. An increase of at least 20 points of the BI was observed in 40% of patients in the intervention group and in 12% of patients in the control group (p< 0.001). Logistic regression analysis with an increase of at least 20 BI-points was significantly and independently associated with patient group (2.358, p< 0.02), BI on admission (0.957, p< 0.001), and the CCI (0.793, p< 0.041).

CONCLUSION

This post hoc analysis of a subsample of older individuals hospitalized for geriatric rehabilitation demonstrates a significant additional improvement in activities of daily living by modification of medication according to FORTA.

Delirium Mediates Incidence of Hospital-Associated Disability Among Older Adults

OBJECTIVE

To examine whether delirium predicts occurrence of hospital-associated disability (HAD), or functional decline after admission, among hospitalized older adults.

DESIGN

Retrospective cross-sectional study.

SETTING AND PARTICIPANTS

General inpatient (non-ICU) units of a large regional Southeastern US academic medical center, involving 33,111 older adults ≥65 years of age admitted from January 1, 2015, to December 31, 2019.

METHODS

Delirium was defined as a score ≥2 on the Nursing Delirium Screening Scale (NuDESC) during hospital admission. HAD was defined as a decline on the Katz Activities of Daily Living (ADL) scale from hospital admission to discharge. Generalized linear mixed models were used to examine the association between delirium and HAD, adjusting for covariates and repeated observations with multiple admissions. We performed multivariate and mediation analyses to examine strength and direction of association between delirium and HAD.

RESULTS

One-fifth (21.6%) of older adults developed HAD during hospitalization and experienced higher delirium rates compared to those not developing HAD (24.3% vs 14.3%, P < .001). Age, presence of delirium, Elixhauser Comorbidity Score, admission cognitive status, admission ADL function, and length of stay were associated (all P < .001) with incident HAD. Mediational analyses found 46.7% of the effect of dementia and 16.7% of the effect of comorbidity was due to delirium (P < .001).

CONCLUSIONS AND IMPLICATIONS

Delirium significantly increased the likelihood of HAD within a multivariate predictor model that included comorbidity, demographics, and length of stay. For dementia and comorbidity, mediation analysis showed a significant portion of their effect attributable to delirium. Overall, these findings suggest that reducing delirium rates may diminish HAD rates.

Association between hospital-acquired functional decline and 2-year readmission or mortality after cardiac surgery in older patients: a multicenter, prospective cohort study

BACKGROUND

Hospital-acquired functional decline (HAFD) is a new predictor of poor prognosis in hospitalized older patients.

AIMS

We aimed to assess the impact of HAFD on the prognosis of older cardiac surgical patients 2 years after discharge.

METHODS

This multicenter prospective cohort study assessed 293 patients with cardiac disease aged ≥ 65 years who underwent cardiac surgery at 7 Japanese hospitals between June 2017 and June 2018. The primary endpoint was the composite outcome of cardiovascular-related readmission and all-cause mortality 2 years after discharge. HAFD was assessed using the total Short Physical Performance Battery at hospital discharge.

RESULTS

The primary outcome was observed in 17.3% of the 254 included patients, and HAFD was significantly associated with the primary outcome. Female sex (hazard ratio [HR], 2.451; 95% confidence interval [CI] 1.232-4.878; P = 0.011), hemoglobin level (HR, 0.839; 95% CI 0.705-0.997; P = 0.046), preoperative frailty (HR, 2.391; 95% CI 1.029-5.556; P = 0.043), and HAFD (HR, 2.589; 95% CI 1.122-5.976; P = 0.026) were independently associated with the primary outcome. The incidence rate of HAFD was 22%, with female sex (odds ratio [OR], 1.912; 95% CI 1.049-3.485; P = 0.034), chronic obstructive pulmonary disease (OR, 3.958; 95% CI 1.413-11.086; P = 0.009), and the time interval (days) between surgery and the start of ambulation (OR, 1.260, 95% CI 1.057-1.502; P = 0.010) identified as significant factors.

DISCUSSION

HAFD was found to be an independent prognostic determinant of the primary outcome 2 years after discharge.

CONCLUSION

HAFD prevention should be prioritized in the hospital care of older cardiac surgery patients.

Relationship Between Skeletal Muscle Quality and Hospital-Acquired Disability in Patients With Sepsis Admitted to the ICU: A Pilot Study

Early risk assessment of functional decline in patients with sepsis is clinically challenging. Recently, there is increasing interest in the nonvolitional evaluation of skeletal muscle quality.

OBJECTIVES

The aim of this study was to assess the relationship between skeletal muscle quality and functional decline after intensive care.

DESIGN SETTING AND PARTICIPANTS

This pilot study was a single-center prospective observational study conducted from March 2021 to February 2022. We included consecutive patients with sepsis who were admitted to our ICU.

MAIN OUTCOMES AND MEASURES

The primary outcome was hospital-acquired disability (HAD), which is defined as a decrease in the Barthel index score of at least 5 points from pre-hospital to hospital discharge. Muscle quality was assessed by: 1) muscle echogenicity with ultrasound and 2) phase angle (PhA) with bioelectrical impedance analysis, both of which were measured on ICU days less than 3, 3-5, 5-7, 7-10, and 10-14. We compared longitudinal changes in muscle echogenicity and PhA between the HAD and non-HAD groups using two-way repeated measures analysis of variance with mixed models.

RESULTS

Among the 22 patients, 7 (31.8%) had HAD. Muscle echogenicity was higher in the HAD group than in the non-HAD group (p < 0.001); however, no interaction effects were found between the two groups (p = 0.189). PhA showed a main effect on each evaluation day in patients (p = 0.040) and a significant interaction effect between the groups, including an early decreased pattern in the HAD group (p = 0.036).

CONCLUSIONS AND RELEVANCE

Higher muscle echogenicity and a decreased PhA pattern are related to HAD. Noninvasive assessment of muscle quality using ultrasound and bioelectrical impedance analysis may be useful in predicting the functional prognosis of patients with sepsis.

Exercise for acutely hospitalised older medical patients

BACKGROUND

Approximately 30% of hospitalised older adults experience hospital-associated functional decline. Exercise interventions that promote in-hospital activity may prevent deconditioning and thereby maintain physical function during hospitalisation. This is an update of a Cochrane Review first published in 2007.

OBJECTIVES

To evaluate the benefits and harms of exercise interventions for acutely hospitalised older medical inpatients on functional ability, quality of life (QoL), participant global assessment of success and adverse events compared to usual care or a sham-control intervention.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was May 2021.

SELECTION CRITERIA

We included randomised or quasi-randomised controlled trials evaluating an in-hospital exercise intervention in people aged 65 years or older admitted to hospital with a general medical condition. We excluded people admitted for elective reasons or surgery.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our major outcomes were 1. independence with activities of daily living; 2. functional mobility; 3. new incidence of delirium during hospitalisation; 4. QoL; 5. number of falls during hospitalisation; 6. medical deterioration during hospitalisation and 7. participant global assessment of success. Our minor outcomes were 8. death during hospitalisation; 9. musculoskeletal injuries during hospitalisation; 10. hospital length of stay; 11. new institutionalisation at hospital discharge; 12. hospital readmission and 13. walking performance. We used GRADE to assess certainty of evidence for each major outcome. We categorised exercise interventions as: rehabilitation-related activities (interventions designed to increase physical activity or functional recovery, but did not follow a specified exercise protocol); structured exercise (interventions that included an exercise intervention protocol but did not include progressive resistance training); and progressive resistance exercise (interventions that included an element of progressive resistance training).

MAIN RESULTS

We included 24 studies (nine rehabilitation-related activity interventions, six structured exercise interventions and nine progressive resistance exercise interventions) with 7511 participants. All studies compared exercise interventions to usual care; two studies, in addition to usual care, used sham interventions. Mean ages ranged from 73 to 88 years, and 58% of participants were women. Several studies were at high risk of bias. The most common domain assessed at high risk of bias was measurement of the outcome, and five studies (21%) were at high risk of bias arising from the randomisation process. Exercise may have no clinically important effect on independence in activities of daily living at discharge from hospital compared to controls (16 studies, 5174 participants; low-certainty evidence). Five studies used the Barthel Index (scale: 0 to 100, higher scores representing greater independence). Mean scores at discharge in the control groups ranged from 42 to 96 points, and independence in activities of daily living was 1.8 points better (0.43 worse to 4.12 better) with exercise compared to controls. The minimally clinical important difference (MCID) is estimated to be 11 points. We are uncertain regarding the effect of exercise on functional mobility at discharge from the hospital compared to controls (8 studies, 2369 participants; very low-certainty evidence). Three studies used the Short Physical Performance Battery (SPPB) (scale: 0 to 12, higher scores representing better function) to measure functional mobility. Mean scores at discharge in the control groups ranged from 3.7 to 4.9 points on the SPPB, and the estimated effect of the exercise interventions was 0.78 points better (0.02 worse to 1.57 better). A change of 1 point on the SPPB represents an MCID. We are uncertain regarding the effect of exercise on the incidence of delirium during hospitalisation compared to controls (7 trials, 2088 participants; very low-certainty evidence). The incidence of delirium during hospitalisation was 88/1091 (81 per 1000) in the control group compared with 70/997 (73 per 1000; range 47 to 114) in the exercise group (RR 0.90, 95% CI 0.58 to 1.41). Exercise interventions may result in a small clinically unimportant improvement in QoL at discharge from the hospital compared to controls (4 studies, 875 participants; low-certainty evidence). Mean QoL on the EuroQol 5 Dimensions (EQ-5D) visual analogue scale (VAS) (scale: 0 to 100, higher scores representing better QoL) ranged between 48.9 and 64.7 in the control group at discharge from the hospital, and QoL was 6.04 points better (0.9 better to 11.18 better) with exercise. A change of 10 points on the EQ-5D VAS represents an MCID. No studies measured participant global assessment of success. Exercise interventions did not affect the risk of falls during hospitalisation (moderate-certainty evidence). The incidence of falls was 31/899 (34 per 1000) in the control group compared with 31/888 (34 per 1000; range 20 to 57) in the exercise group (RR 0.99, 95% CI 0.59 to 1.65). We are uncertain regarding the effect of exercise on the incidence of medical deterioration during hospitalisation (very low-certainty evidence). The incidence of medical deterioration in the control group was 101/1417 (71 per 1000) compared with 96/1313 (73 per 1000; range 44 to 120) in the exercise group (RR 1.02, 95% CI 0.62 to 1.68). Subgroup analyses by different intervention categories and by the use of a sham intervention were not meaningfully different from the main analyses.

AUTHORS' CONCLUSIONS

Exercise may make little difference to independence in activities of daily living or QoL, but probably does not result in more falls in older medical inpatients. We are uncertain about the effect of exercise on functional mobility, incidence of delirium and medical deterioration. Certainty of evidence was limited by risk of bias and inconsistency. Future primary research on the effect of exercise on acute hospitalisation could focus on more consistent and uniform reporting of participant's characteristics including their baseline level of functional ability, as well as exercise dose, intensity and adherence that may provide an insight into the reasons for the observed inconsistencies in findings.

Functional trajectories associated with acute illness and hospitalization in oldest old patients: Impact on mortality

Background: The literature pays low attention to functional changes during acute illness in older patients. Our main objectives were to separately describe the different functional changes occurring before and after hospital admission in oldest old medical patients, to investigate their association with mortality, and identify predictors associated with in-hospital failure to recover function.

Methods: Secondary analysis of data from a prospective cohort study conducted in a tertiary teaching hospital. The study followed the STROBE criteria. The sample included 604 consecutive patients aged 65 or older hospitalized for acute illness, discharged alive, and not fully dependent at baseline. Activities of daily living measured at baseline, admission, and discharge were used to classify patients into four functional trajectories depending on whether they decline or remain stable between baseline and admission (prehospital) and whether they decline, remain stable, or recover baseline function between admission and discharge (in-hospital). Multivariate models were used to test the association between functional trajectories with mortality, and predictors for in-hospital recovery.

Results: Functional trajectories were: “stable-stable” (18%); “decline-recovery” (18%); “decline-no recovery” (53%); “in-hospital decline” (11%). Prehospital decline occurred in 75% and 64% were discharged with worse function than baseline. “In-hospital decline” and “decline-no recovery” trajectories were independently associated with higher 6- and 12-month mortality. Extent of prehospital decline and dementia were predictors of failure to in-hospital recovery.

Conclusion: In acutely ill older people, differentiating between prehospital and in-hospital functional changes has prognostic implications. Lack of functional regain at discharge is associated with higher mortality at 6- and 12-months.

The Predictive Validity of Functional Outcome Measures With Discharge Destination for Hospitalized Medical Patients

Objective

To investigate the predictive validity for discharge to home or facility of 4 functional mobility outcome measures.

Design

Retrospective, observational study.

Setting

Urban, academic hospital in the United States.

Participants

Adult patients (N=3999) admitted to medical units between June 1, 2019, and February 29, 2020, with 2 or more recorded scores on each of 4 tools: Activity Measure for Post-Acute Care (AM-PAC) 6-Clicks Basic Mobility and Daily Activity, Henry Ford Mobility Level, and The Johns Hopkins Highest Level of Mobility.

Interventions

Not applicable.

Main Outcome Measures

Mobility scores and discharge destination.

Results

For the 3999 subjects, 51.4% went home at discharge and had higher mean scores on each measure than those not returning home. Both early (I) and later (II) time point for each measure had positive predictability for discharge home. AM-PAC 6-Clicks had the highest confidence intervals for early and later recorded scores. The c-statistic value for Basic Mobility I (cut point=16) was 0.74 and for II (cut point=18) was, 0.79. The value for Daily Activity I (cut point=18) was 0.75 and for Daily Activity II (cut point=18) was 0.80). The Johns Hopkins Highest Level of Mobility and Henry Ford Mobility Level measures were less discriminative at initial score (c-statistic 0.704 and 0.665, respectively) and final score (c-statistic 0.74 and 0.75, respectively).

Conclusions

Functional outcome measures have good predictive validity for discharge destination. The AM-PAC Basic mobility score appears to have a slightly higher confidence interval than the other tools in this study design.

Nursing, frailty, functional decline and models of care in relation to older people receiving long-term care: a scoping review protocol

INTRODUCTION

Older people receiving healthcare in long-term care contexts (eg, home healthcare, sheltered housing and nursing home contexts) are especially vulnerable to developing frailty and functional decline. Considering the negative effects associated with these conditions and the possibility of preventing them from progressing, it is vital that nurses possess a broad knowledge base related to them. Particularly as prevention related to these conditions lies well within their remit. Such knowledge could guide the development of effective models of care, ensuring continuity and, hence, quality of care. Our objective will be to review published literature on existing models of care targeting frailty and/or functional decline and how these conditions are described by older people themselves, significant others and nurses in relation to long-term care.

METHODS AND ANALYSIS

The scoping review will be conducted in accordance with Arksey and O'Malley's methodological framework. Recent methodological developments will be considered. PubMed, CINAHL and PsycINFO will be searched. Eligibility criteria will be peer-reviewed papers and written in English. All types of study designs will be eligible and included papers will be quality and ethically assessed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-Protocol checklist for protocols and the PRISMA for Scoping Reviews checklist were followed in this paper.

ETHICS AND DISSEMINATION

As the study outlined in this protocol is a scoping review, no ethics approval was needed for this protocol nor for the upcoming study. The findings will be published in an open-access, peer-reviewed journal. Additionally, the findings will guide a research project following the Medical Research Council's framework for developing and evaluating complex interventions. Thus, supporting us in developing a model of care related to the detection and prevention of frailty and/or functional decline among older people in a long-term care context.

Effect of inpatient rehabilitation treatment ingredients on functioning, quality of life, length of stay, discharge destination, and mortality among older adults with unplanned admission: an overview review

BACKGROUND

To synthesise the evidence for the effectiveness of inpatient rehabilitation treatment ingredients (versus any comparison) on functioning, quality of life, length of stay, discharge destination, and mortality among older adults with an unplanned hospital admission.

METHODS

A systematic search of Cochrane Library, MEDLINE, Embase, PsychInfo, PEDro, BASE, and OpenGrey for published and unpublished systematic reviews of inpatient rehabilitation interventions for older adults following an unplanned admission to hospital from database inception to December 2020. Duplicate screening for eligibility, quality assessment, and data extraction including extraction of treatment components and their respective ingredients employing the Treatment Theory framework. Random effects meta-analyses were completed overall and by treatment ingredient. Statistical heterogeneity was assessed with the inconsistency-value (I2).

RESULTS

Systematic reviews (n = 12) of moderate to low quality, including 44 non-overlapping relevant RCTs were included. When incorporated in a rehabilitation intervention, there was a large effect of endurance exercise, early intervention and shaping knowledge on walking endurance after the inpatient stay versus comparison. Early intervention, repeated practice activities, goals and planning, increased medical care and/or discharge planning increased the likelihood of discharge home versus comparison. The evidence for activities of daily living (ADL) was conflicting. Rehabilitation interventions were not effective for functional mobility, strength, or quality of life, or reduce length of stay or mortality. Therefore, we did not explore the potential role of treatment ingredients for these outcomes.

CONCLUSION

Benefits observed were often for subgroups of the older adult population e.g., endurance exercise was effective for endurance in older adults with chronic obstructive pulmonary disease, and early intervention was effective for endurance for those with hip fracture. Future research should determine whether the effectiveness of these treatment ingredients observed in subgroups, are generalisable to older adults more broadly. There is a need for more transparent reporting of intervention components and ingredients according to established frameworks to enable future synthesis and/or replication.

Validation of Screening Tools for Predicting the Risk of Functional Decline in Hospitalized Elderly Patients

BACKGROUND

Functional decline and increased dependence on others are common health issues among hospitalized elderly patients. However, a well-validated screening tool for predicting functional decline in elderly patients is still lacking. The current study therefore aimed to evaluate and compare the diagnostic accuracy of the Identification of Seniors at Risk-Hospitalized Patients (ISAR-HP), Variable Indicative of Placement Risk (VIP), and Score Hospitalier d' Evaluation du Risque de Perte d'Autonomie (SHERPA) in predicting functional decline 30 days after discharge in older patients admitted to an acute hospital ward.

METHODS

A prospective, longitudinal study was conducted in 197 elderly inpatients at the internal medicine ward of a teaching hospital in central Taiwan. Data were collected twice, first within 48 h after hospitalization and second via a telephone interview 30 days after hospital discharge. Variables included demographic data, Barthel Index of activities of daily living (ADL), and screening instruments. The Barthel Index was used to measure functional disability. Functional decline was defined as a decline of at least five points on the Barthel Index 30 days after discharge compared to that at pre-admission.

RESULTS

Patients had a mean age of 77.7 years, with 55.7% being female. Functional decline was observed in 39.1% of all patients. The best cutoff point, sensitivity, specificity, and area under the receiver operating characteristic curve were 2.5, 96.1%, 52.5%, and 0.751 for ISAR-HP; 1.5, 83.1%, 62.5%, and 0.761 for VIP; and 4.75, 89.6%, 54.2%, and 0.758 for SHERPA, respectively.

CONCLUSIONS

All three instruments showed moderate diagnostic accuracy as indicated by their best cutoff points. Therefore, the results presented herein can guide health care professionals in selecting the appropriate assessment tool for predicting functional decline among hospitalized elderly patients in a clinical setting.

Patient-related risk factors for in-hospital functional decline in older adults: A systematic review and meta-analysis

BACKGROUND

Functional decline (FD) is a common and serious problem among hospitalised older adults.

OBJECTIVE

This systematic review and meta-analysis aims to identify patient-related risk factors for in-hospital FD in older adults.

METHODS

Previous reviews on this topic (1970-2007) and the databases PubMed, Embase, and CINAHL (January 2007-December 2020) were searched. Reference lists of included articles were screened. Studies investigating patient-related risk factors for FD from (pre)admission to discharge in older adults admitted to an acute geriatric or internal medical unit were included. Study quality was assessed using the modified Newcastle-Ottawa Scale. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were estimated using random-effects models. The quality of evidence was assessed using GRADE.

RESULTS

Twenty-nine studies met the inclusion criteria. Statistically significant risk factors were living in a nursing home (OR, 2.42; 95% CI, 1.29-4.52), impairment in instrumental activities of daily living (OR, 2.08; 95% CI, 1.51-2.86), history of falls (OR, 1.71; 95% CI, 1.00-2.92), cognitive impairment (OR, 1.83; 95% CI, 1.56-2.14), dementia (OR, 1.71; 95% CI, 1.23-2.38), delirium (OR, 2.34; 95% CI, 1.88-2.93), (risk of) malnutrition (OR, 1.76; 95% CI, 1.03-3.03), hypoalbuminemia (OR, 1.79; 95% CI, 1.36-2.36), comorbidity (OR, 1.09; 95% CI, 1.03-1.16), and the presence of pressure ulcers (OR, 3.33; 95% CI, 1.82-6.09). The narrative synthesis suggested prehospital FD, needing assistance with walking, and low body mass index as additional risk factors.

CONCLUSIONS

Several patient-related risk factors for in-hospital FD were identified that can be used at hospital admission to identify older patients at risk of FD.

Hospital-Acquired Functional Decline and Clinical Outcomes in Older Cardiac Surgical Patients: A Multicenter Prospective Cohort Study

This study aimed to determine the effect of hospital-acquired functional decline (HAFD) on prognosis, 1-year post-hospital discharge, of older patients who had undergone cardiac surgery in seven Japanese hospitals between June 2017 and June 2018. This multicenter prospective cohort study involved 247 patients with cardiac disease aged ≥65 years. HAFD was defined as a decrease in the short physical performance battery at hospital discharge compared with before surgery. Primary outcomes included a composite outcome of frailty severity, total mortality, and cardiovascular readmission 1-year post-hospital discharge. Secondary outcomes were changes in the total score and sub-item scores in the Ki-hon Checklist (KCL), assessed pre- and 1-year postoperatively. Poor prognostic outcomes were observed in 33% of patients, and multivariate analysis identified HAFD (odds ratio [OR] 3.43, 95% confidence interval [CI] 1.75–6.72, p < 0.001) and low preoperative gait speed (OR 2.47, 95% CI 1.18–5.17, p = 0.016) as independent predictors of poor prognosis. Patients with HAFD had significantly worse total KCL scores and subscale scores for instrumental activities of daily living, mobility, oral function, and depression at 1-year post-hospital discharge. HAFD is a powerful predictor of prognosis in older patients who have undergone cardiac surgery.

The predictive utility of functional status at discharge: a population-level cohort analysis

Background

Functional status is a patient-important, patient-centered measurement. The utility of functional status measures to inform post-discharge patient needs is unknown. We sought to examine the utility of routinely collected functional status measures gathered from older hospitalized patients to predict a panel of post-discharge outcomes.

Methods

In this population-based retrospective cohort study, Adults 65+ discharged from an acute hospitalization between 4 November 2008 and 18 March 2016 in Ontario, Canada and received an assessment of functional status at discharge using the Health Outcomes for Better Information and Care tool were included. Multivariable regression analysis was used to determine the relationship between functional status and emergency department (ED) re-presentation, hospital readmission, long term care facility (LTCF) admission or wait listing (‘LTCF readiness’), and death at 180 days from discharge.

Results

A total of 80 020 discharges were included. 38 928 (48.6%) re-presented to the ED, 24 222 (30.3%) were re-admitted, 5 037 (6.3%) were LTCF ready, and 9 047 (11.3%) died at 180 days. Beyond age, diminished functional status at discharge was the factor most associated with LTCF readiness (adjusted Odds Ratio [OR] 4.11 for those who are completely dependent for activities of daily living compared to those who are independent; 95% Confidence Interval [CI]: 3.70-4.57) and death (OR 3.99; 95% CI: 3.67-4.35). Functional status also had a graded relationship with each outcome and improved the discriminability of the models predicting death and LTCF readiness (p<0.01) but not ED re-presentation or hospital re-admission.

Conclusion

Routinely collected functional status at discharge meaningfully improves the prediction of long term care home readiness and death. The routine assessment of functional status can inform post-discharge care and planning for older adults.

Systematic review of prediction models for postacute care destination decision-making

OBJECTIVE

This article reports a systematic review of studies containing development and validation of models predicting postacute care destination after adult inpatient hospitalization, summarizes clinical populations and variables, evaluates model performance, assesses risk of bias and applicability, and makes recommendations to reduce bias in future models.

MATERIALS AND METHODS

A systematic literature review was conducted following PRISMA guidelines and the Cochrane Prognosis Methods Group criteria. Online databases were searched in June 2020 to identify all published studies in this area. Data were extracted based on the CHARMS checklist, and studies were evaluated based on predictor variables, validation, performance in validation, risk of bias, and applicability using the Prediction Model Risk of Bias Assessment Tool (PROBAST) tool.

RESULTS

The final sample contained 28 articles with 35 models for evaluation. Models focused on surgical (22), medical (5), or both (8) populations. Eighteen models were internally validated, 10 were externally validated, and 7 models underwent both types. Model performance varied within and across populations. Most models used retrospective data, the median number of predictors was 8.5, and most models demonstrated risk of bias.

DISCUSSION AND CONCLUSION

Prediction modeling studies for postacute care destinations are becoming more prolific in the literature, but model development and validation strategies are inconsistent, and performance is variable. Most models are developed using regression, but machine learning methods are increasing in frequency. Future studies should ensure the rigorous variable selection and follow TRIPOD guidelines. Only 14% of the models have been tested or implemented beyond original studies, so translation into practice requires further investigation.

Restoration of dysnatremia and acute kidney injury benefits outcomes of acute geriatric inpatients

Dysnatremia and dyskalemia are common problems in acutely hospitalized elderly patients. These disorders are associated with an increased risk of mortality and functional complications that often occur concomitantly with acute kidney injury in addition to multiple comorbidities. In a single-center prospective observational study, we recruited 401 acute geriatric inpatients. In-hospital outcomes included all-cause mortality, length of stay, and changes in functional status as determined by the Activities of Daily Living (ADL) scale, Eastern Cooperative Oncology Group (ECOG) performance, and Clinical Frailty Scale (CFS). The prevalence of dysnatremia alone, dyskalemia alone, and dysnatremia plus dyskalemia during initial hospitalization were 28.4%, 14.7% and 32.4%, respectively. Patients with electrolyte imbalance exhibited higher mortality rates and longer hospital stays than those without electrolyte imbalance. Those with initial dysnatremia, or dysnatremia plus dyskalemia were associated with worse ADL scores, ECOG performance and CFS scores at discharge. Subgroup analyses showed that resolution of dysnatremia was related to reduced mortality risk and improved CFS score, whereas recovery of renal function was associated with decreased mortality and better ECOG and CFS ratings. Our data suggest that restoration of initial dysnatremia and acute kidney injury during acute geriatric care may benefit in-hospital survival and functional status at discharge.

Resistance exercise intervention on muscular strength and power, and functional capacity in acute hospitalized older adults: a systematic review and meta-analysis of 2498 patients in 7 randomized clinical trials

To date, no meta-analytical study evaluating the benefits of resistance exercise intervention on muscular strength and power and functional capacity in acute hospitalized older adults was conducted. Then, to synthesize the emerging evidence on the effects of resistance exercise intervention on muscular strength and power and functional capacity in acute hospitalized older adults, two independent authors performed a systematic search (PubMed, Scopus, Web of Science, and SciELO) until January 2021. Randomized clinical trials were included regarding the effects of resistance exercise and hospital usual care. The Cochrane Collaboration assessment tool was used to analyze the risk of bias. The comparisons included muscular strength (isometric handgrip strength and one-repetition maximum test of leg press), muscular power (output during leg press exercise), and functional capacity (timed-up-and-go, and short physical performance battery). Resistance exercise intervention increased muscular strength (isometric handgrip strength: mean difference = 2.50 kg, 95% confidence interval (CI) = 1.33, 3.67; and one-repetition maximum test of leg press: mean difference = 19.28 kg, 95% confidence interval = 14.70, 23.86) and muscular power (mean difference = 29.52 W, 95% confidence interval = 28.84, 30.21), and functional capacity (timed-up-and-go: mean difference = 3.40 s, 95% confidence interval = 0.47, 6.36; and short physical performance battery: mean difference = 1.29 points, 95% confidence interval = 0.10, 2.48) at discharge compared with hospital usual care. This meta-analysis endorses the increase of muscular strength and power gains and improving the functional capacity in favor of resistance exercise intervention in acute hospitalized older adults.

The Aging Muscle in Experimental Bed Rest: A Systematic Review and Meta-Analysis

Background: Maintaining skeletal muscle mass and function in aging is crucial for preserving the quality of life and health. An experimental bed rest (BR) protocol is a suitable model to explore muscle decline on aging during inactivity. Objective: The purpose of this systematic review and meta-analysis was, therefore, to carry out an up-to-date evaluation of bed rest, with a specific focus on the magnitude of effects on muscle mass, strength, power, and functional capacity changes as well as the mechanisms, molecules, and pathways involved in muscle decay. Design: This was a systematic review and meta-analysis study. Data sources: We used PubMed, Medline; Web of Science, Google Scholar, and the Cochrane library, all of which were searched prior to April 23, 2020. A manual search was performed to cover bed rest experimental protocols using the following key terms, either singly or in combination: "Elderly Bed rest," "Older Bed rest," "Old Bed rest," "Aging Bed rest," "Aging Bed rest," "Bed-rest," and "Bedrest". Eligibility criteria for selecting studies: The inclusion criteria were divided into four sections: type of study, participants, interventions, and outcome measures. The primary outcome measures were: body mass index, fat mass, fat-free mass, leg lean mass, cross-sectional area, knee extension power, cytokine pattern, IGF signaling biomarkers, FOXO signaling biomarkers, mitochondrial modulation biomarkers, and muscle protein kinetics biomarkers. Results: A total of 25 studies were included in the qualitative synthesis, while 17 of them were included in the meta-analysis. In total, 118 healthy elderly volunteers underwent 5-, 7-, 10-, or 14-days of BR and provided a brief sketch on the possible mechanisms involved. In the very early phase of BR, important changes occurred in the skeletal muscle, with significant loss of performance associated with a lesser grade reduction of the total body and muscle mass. Meta-analysis of the effect of bed rest on total body mass was determined to be small but statistically significant (ES = -0.45, 95% CI: -0.72 to -0.19, P < 0.001). Moderate, statistically significant effects were observed for total lean body mass (ES = -0.67, 95% CI: -0.95 to -0.40, P < 0.001) after bed rest intervention. Overall, total lean body mass was decreased by 1.5 kg, while there was no relationship between bed rest duration and outcomes (Z = 0.423, p = 672). The meta-analyzed effect showed that bed rest produced large, statistically significant, effects (ES = -1.06, 95% CI: -1.37 to -0.75, P < 0.001) in terms of the knee extension power. Knee extension power was decreased by 14.65 N/s. In contrast, to other measures, meta-regression showed a significant relationship between bed rest duration and knee extension power (Z = 4.219, p < 0.001). Moderate, statistically significant, effects were observed after bed rest intervention for leg muscle mass in both old (ES = -0.68, 95% CI: -0.96 to -0.40, P < 0.001) and young (ES = -0.51, 95% CI: -0.80 to -0.22, P < 0.001) adults. However, the magnitude of change was higher in older (MD = -0.86 kg) compared to younger (MD = -0.24 kg) adults. Conclusion: Experimental BR is a suitable model to explore the detrimental effects of inactivity in young adults, old adults, and hospitalized people. Changes in muscle mass and function are the two most investigated variables, and they allow for a consistent trend in the BR-induced changes. Mechanisms underlying the greater loss of muscle mass and function in aging, following inactivity, need to be thoroughly investigated.

Hospitalization-Associated Disability After Cardiac Surgery in Elderly Patients - Exploring the Risk Factors Using Machine Learning Algorithms

Background: Hospitalization-associated disability (HAD) is associated with prolonged functional decline and increased mortality after discharge. Therefore, we examined the incidence and risk factors associated with HAD in elderly patients undergoing cardiac surgery in Japan.

Methods and Results: We retrospectively examined 2,262 elderly patients who underwent elective cardiac surgery at Sakakibara Heart Institute. HAD was defined as a functional decline between time of admission and discharge measured by the Barthel Index. We analyzed clinical characteristics using machine learning algorithms to identify the risk factors associated with HAD. After excluding 203 patients, 2,059 patients remained, of whom 108 (5.2%) developed HAD after cardiac surgery. The risk factors identified were age, serum albumin concentration, estimated glomerular filtration rate, Revised Hasegawa’s Dementia Scale, N-terminal pro B-type natriuretic peptide, vital capacity, preoperative Short Physical Performance Battery (SPPB) score, operation times, cardiopulmonary bypass times, ventilator times, length of postoperative intensive care unit stay, and postoperative ambulation start day. The highest incidence of HAD was found in patients with an SPPB score ≤9 and in those who started ambulation >6 days after surgery (76.9%).

Conclusions: Several risk factors for HAD are components of frailty, suggesting that preoperative rehabilitation to reduce the risk of HAD is feasible. Furthermore, the association between HAD and a delayed start of ambulation reaffirms the importance of early mobilization and rehabilitation.

Association of hospitalization with driving reduction and cessation in older adults

BACKGROUND

Driving has not been considered as part of the social cost of acute illness and may go unnoticed in the post-hospital care of older adults. Decreases in driving after hospitalization and at-risk populations have not been investigated.

OBJECTIVE

To determine the association between driving reduction and cessation and hospitalization in older adults by using nationally representative data.

DESIGN

Retrospective cohort analysis.

SETTING

Health and Retirement Study survey from 2004 to 2014.

PARTICIPANTS

Adults aged 65 years and older who were able to drive and had an available car (n = 12,110; 40,364 interviews).

MEASUREMENTS

Self-report of a hospitalization requiring an overnight stay, changes in driving patterns including driving cessation or limitations over a 2-year period, comorbid conditions, health utilization, and behaviors.

RESULTS

Of hospitalizations in adults aged 65 years and older, 22% were associated with a decrease in driving patterns within 2 years. The relative risk of a reduction or cessation in driving was 1.62 (95% CI: 1.54, 1.70, p < 0.001) when there was a hospitalization compared with when a hospitalization did not occur. Baseline functional, cognitive, and visual impairment, fair or poor self-rated health, and diabetes were identified as independent risk factors for decreased driving patterns after hospitalization.

CONCLUSIONS

Changes in driving patterns are common after a hospitalization in older adults. The findings suggest that driving, although not a current goal of post-hospital care, is important to the continued autonomy and community mobility of older adults and needs to be addressed as part of discharge planning and their recovery.

Prevalence and predictors of hospital-acquired functional decline in patients with sepsis admitted to the intensive care unit

Although sepsis is known to cause functional decline, the prevalence and predictors of hospital-acquired functional decline (HAFD) in patients with sepsis are unclear. The purpose of this study was to investigate the prevalence and predictors of HAFD in patients with sepsis admitted to the ICU. This study is a single-center retrospective observational study from January 2014 to December 2019. We included all consecutive patients with sepsis who received rehabilitation in our ICU. The primary outcome was HAFD, which was defined as a decrease in at least five points of the Barthel index mobility score from prehospital to hospital discharge. We described the prevalence of HAFD and investigated the predictors of HAFD using the multivariate logistic regression analysis adjusting for potential confounders. Among 134 patients, 57 patients (42.5%) had HAFD. The longer time to initial ambulation and lower prehospital walking ability were associated with HAFD (adjusted odds ratio [OR] 1.07; 95% confidence interval [CI], 1.03-1.10 and adjusted OR 0.79; 95% CI, 0.66-0.95, respectively). In conclusion, nearly half of the patients with sepsis who received rehabilitation developed HAFD. Lower functional status prior to hospitalization and the longer time to initial ambulation was associated with HAFD, indicating the potential importance of early ambulation among septic patients in the ICU.

Association of phase angle with hospital-acquired functional decline in older patients undergoing cardiovascular surgery

OBJECTIVE

The aim of this study was to examine whether preoperative phase angle (PhA) measured by bioelectrical impedance analysis was associated with a hospital-acquired functional decline in older patients undergoing cardiovascular surgery.

METHODS

This was an observational study of prospectively collected data of 114 patients (>65 y of age) with cardiovascular disease who underwent elective cardiovascular surgery between September 2019 and August 2020. Patients were classified into tertiles based on PhA levels. Factors associated with the occurrence of hospital-acquired functional decline (postoperative recovery to preoperative physical function was not possible) were analyzed using univariate and multivariate analyses.

RESULTS

Patients in the low PhA group were significantly older than those in the middle and high PhA groups; were predominantly women; had higher New York Heart Association cardiovascular and EuroSCORE severity scores; and had significantly lower levels of body mass index, Geriatric Nutritional Risk Index, hemoglobin, and albumin. There was a significant correlation between PhA and nutrition and physical function. The incidence of hospital-acquired functional decline occurred in 26.3% of all patients, with a significantly higher incidence in patients in the low PhA group. Multivariate analysis showed that PhA was extracted as a factor for the hospital-acquired functional decline in all the models.

CONCLUSIONS

PhA was associated with hospital-acquired functional decline in older patients undergoing cardiovascular surgery. PhA is likely to be a comprehensive indicator of physical health that indicates nutritional status, physical function, and geriatric syndrome (frailty/sarcopenia), and is an important predictor of hospital-acquired functional decline in this group of older patients.

Older medical outliers on surgical wards: impact on 6-month outcomes

BACKGROUND

Medical patients are on occasion admitted transiently to surgical wards when more appropriate wards are at capacity, potentially leading to suboptimal care. The aim of this study was to compare 6-month outcomes in older adults diagnosed with medical conditions in the ED then admitted inappropriately to surgical wards (defined as outliers), with outcomes in comparable patients admitted to medical wards (controls).

METHODS

In a matched cohort study, 100 consecutive medical outliers from the ED aged 75 years and over were matched according to age, sex and diagnosis to 200 controls. Collected data included number of diagnoses reported in acute care, level of patient illness severity, length of stay, mortality and destination of patients discharged from acute care units (home, rehabilitation facility, nursing home or palliative care facility). An assessment was made of patient vital status and living environment (home, nursing home or hospital) at 6 months post-ED admission.

RESULTS

Mean age was 85.6 years. The most common ED diagnoses were gait disorders/falls (18%), neurological disorders (17%) and exhaustion (16%). Outliers displayed lower illness severity levels (0.001) and shorter lengths of stay from ED admission to acute care discharge (p=0.040). Subsequent to acute care, outliers were less commonly discharged home (45% vs 59%) and more commonly discharged to rehabilitation facilities (42% vs 28%). At 6 months post-ED admission, multivariable regression analysis showed that outlier status (OR=0.44 (0.25-0.83); p=0.011) and numbers of diagnoses reported in acute care (OR=0.87 (0.76-0.98); p=0.028) were independently associated with lower probability of living at home.

CONCLUSION

Outlying of older patients to surgical wards negatively affects their prospects of living at home at 6 months after hospital admission. Older patients hospitalised via the ED are entitled to appropriate medical care.

Trajectories of functional performance recovery after inpatient geriatric rehabilitation: an observational study

Objective

To identify functional performance trajectories and the characteristics of people who receive inpatient geriatric rehabilitation after hospital admissions.

Design, setting, participants

REStORing health of acutely unwell adulTs (RESORT) is an observational, prospective, longitudinal inception cohort study of consecutive patients admitted to geriatric rehabilitation wards at the Royal Melbourne Hospital. Recruitment commenced on 15 October 2017.

Main outcome measures

Functional performance, assessed with the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales two weeks before acute hospitalisation, on admission to and discharge from geriatric rehabilitation, and three months after discharge from geriatric rehabilitation.

Results

A total of 618 rehabilitation patients were included in our analysis. For each of the two scales, three distinct functional performance trajectories were identified by latent class growth modelling: poor at baseline and 3‐month follow‐up (remained poor: ADL, 6.6% of patients; IADL, 42%), good at baseline but poor recovery (deteriorated: ADL, 33%; IADL, 20%), and good at baseline and good recovery (recovered: ADL, 60%; IADL, 35%). Higher Clinical Frailty Scale (CFS) score (v recovered, per point: odds ratio [OR], 2.51; 95% CI, 1.64–3.84) and cognitive impairment (OR, 6.33; 95% CI, 2.09–19.1) were associated with greater likelihood of remaining poor in ADL, and also with deterioration (CFS score: OR, 1.76; 95% CI, 1.45–2.13; cognitive impairment: OR, 1.87; 95% CI, 1.24–2.82). Higher CFS score (OR, 1.64; 95% CI, 1.37–1.97) and cognitive impairment (OR, 3.60; 95% CI, 2.31–5.61) were associated with remaining poor in IADL, and higher CFS score was also associated with deterioration (OR, 1.63; 95% CI, 1.33–1.99).

Conclusions

Based on ADL assessments, most people who underwent inpatient geriatric rehabilitation regained their baseline functional performance. As higher CFS score and cognitive impairment were associated with poorer functional recovery, assessing frailty and cognition at hospital admission could assist intervention and discharge planning.

Towards "mobility is medicine": Socioecological factors and hospital mobility in older adults

BACKGROUND

Understanding the factors that influence hospital mobility, especially in the context of a heightened focus on falls prevention, is needed to improve care.

OBJECTIVE

This qualitative study uses a socioecological framework to explore factors that influence hospital mobility in older adults.

DESIGN

Qualitative research PARTICIPANTS: Semi-structured interviews and focus groups were conducted with medically-ill hospitalized older adults (n = 19) and providers (hospitalists, nurses, and physical and occupational therapists (n = 48) at two hospitals associated with an academic health system.

APPROACH

Interview and focus group guides included questions on perceived need for mobility, communication about mobility, hospital mobility culture, and awareness of patients' walking activity. Data were analyzed thematically and mapped onto the constructs of the socioecological model.

KEY RESULTS

A consistent theme among patients and providers was that "mobility is medicine." Categories of factors reported to influence hospital walking activity included intrapersonal factors (patients' health status, fear of falls), interpersonal factors (patient-provider communication about mobility), organizational factors (clarity about provider roles and responsibilities, knowledge of safe patient handling, reliance on physical therapy for mobility), and environmental factors (falls as a never event, patient geographical locations on hospital units). Several of these factors were identified as potentially modifiable targets for intervention. Patients and providers offered recommendations for improving awareness of patient's ambulatory activity, assigning roles and responsibility for mobility, and enhancing education and communication between patients and providers across disciplines.

CONCLUSION

Patients and providers identified salient factors for future early mobility initiatives targeting hospitalized older adults. Consideration of these factors across all stages of intervention development and implementation will enhance impact and sustainability.

Health-related quality of life, functional decline, and long-term mortality in older patients following hospitalisation due to COVID-19

Background

Older people are particularly vulnerable to severe COVID-19. Little is known about long-term consequences of COVID-19 on health-related quality of life (HR-QoL) and functional status in older people, and the impact of age in this context. We aimed to study age-related change in health-related quality of life, functional decline and mortality among older patients 6 months following hospitalisation due to COVID-19.

Methods

This was a cohort study including patients aged 60 years and older admitted to four general hospitals in South-Eastern Norway due to COVID-19, from March 1 up until July 1, 2020. Patients who were still alive were invited to attend a six-month follow-up. Change in HR-QoL and functional status compared to before the COVID-19 hospitalisation were assessed using the EuroQol 5-dimensional-5 levels questionnaire (EQ. 5D-5L). A change in visual analogue scale (VAS) score of 7 or more was considered clinically relevant.

Results

Out of 216 patients aged 60 years and older that were admitted to hospital due to COVID-19 during the study period, 171 were still alive 180 days after hospital admission, and 106 patients (62%) attended the six-month follow-up. Mean age was 74.3 years, 27 patients (26%) had experienced severe COVID-19. Fifty-seven participants (54%) reported a decrease in the EQ. 5D-5L VAS score after 6 months, with no significant difference between persons aged 75 years and older compared to younger. Seventy participants (66%) reported a negative change in any of the dimensions of the EQ. 5D-5L, with impaired ability to perform activities of daily life (35%), reduced mobility (33%) and having more pain or discomfort (33%) being the most commonly reported changes. Forty-six participants (43%) reported a negative change in cognitive function compared to before the COVID-19 hospitalisation. Six-month mortality was 21%, and increased with increasing age.

Conclusions

More than half of the patients reported a negative change in HR-QoL 6 months following hospitalisation due to COVID-19, and one out of three experienced a persistently impaired mobility and ability to carry out activities of daily living. The results suggest awareness of long-term functional decline in older COVID-19 patients.

Construct Validity, Test-Retest Reliability, Sensitivity to Change, and Feasibility of the Patient-Specific Functional Scale in Acutely Hospitalized Older Patients With and Without Cognitive Impairment

BACKGROUND AND PURPOSE

The Patient-Specific Functional Scale (PSFS) as an individualized patient-reported outcome measure may allow to assess limitations and changes in self-determined functional activities most important to an older patient in the acute care setting. However, its clinimetric properties have not yet been evaluated in these patients. The study aimed to investigate the construct validity, test-retest reliability, sensitivity to change, and feasibility of the PSFS in acutely hospitalized older patients with and without cognitive impairment (CI).

METHODS

The clinimetric properties of the PSFS were investigated by secondary data analysis from a prospective observational cohort study examining physical activity and mobility in acutely hospitalized older patients. In this analysis, 120 older patients-83.0 (6.4) years-with (Mini-Mental State Examination [MMSE] 18-23, n = 52) and without CI (MMSE ≥24, n = 68) receiving early multidisciplinary geriatric rehabilitation in acute care were included. Construct validity was assessed by Spearman correlations (rs) with the Activity-specific Balance Confidence Scale (ABC-6), Short Falls Efficacy Scale-International (Short FES-I), EuroQoL-5 Dimensions (EQ-5D), Short Physical Performance Battery (SPPB), de Morton Mobility Index (DEMMI), and Barthel Index (BI); test-retest reliability within 24 hours by intraclass correlation coefficients (ICCs); sensitivity to change by standardized response means (SRMs) calculated for treatment effects, and feasibility by completion rates/times and floor/ceiling effects.

RESULTS

The PSFS showed fair to moderate correlations with all construct variables in patients with CI (rs = 0.31 to 0.53). In patients without CI, correlations were fair for the ABC-6, FES-I, EQ-5D, and BI (rs = |0.27 to 0.36|), but low for the SPPB and DEMMI (rs = -0.04 to 0.14). Test-retest reliability (both: ICC = 0.76) and sensitivity to change (CI: SRM = 1.10, non-CI: SRM = 0.89) were excellent in both subgroups. Excellent feasibility was documented by high completion rates (>94%), brief completion times (<8 min), and no floor/ceiling effects in both subgroups.

CONCLUSIONS

The PSFS has adequate clinimetric properties for assessing patient-specific functional limitations and changes in acutely hospitalized older patients with and without CI. It might be an appropriate complement to traditional functional scales to enhance patient-centeredness in clinical geriatric assessment.

Skeletal Muscle Energetics and Mitochondrial Function Are Impaired Following 10 Days of Bed Rest in Older Adults

Background

Older adults exposed to periods of inactivity during hospitalization, illness, or injury lose muscle mass and strength. This, in turn, predisposes poor recovery of physical function upon reambulation and represents a significant health risk for older adults. Bed rest (BR) results in altered skeletal muscle fuel metabolism and loss of oxidative capacity that have recently been linked to the muscle atrophy program. Our primary objective was to explore the effects of BR on mitochondrial energetics in muscle from older adults. A secondary objective was to examine the effect of β-hydroxy-β-methylbuturate (HMB) supplementation on mitochondrial energetics.

Methods

We studied 20 older adults before and after a 10-day BR intervention, who consumed a complete oral nutritional supplement (ONS) with HMB (3.0 g/d HMB, n = 11) or without HMB (CON, n = 9). Percutaneous biopsies of the vastus lateralis were obtained to determine mitochondrial respiration and H₂O₂ emission in permeabilized muscle fibers along with markers of content. RNA sequencing and lipidomics analyses were also conducted.

Results

We found a significant up-regulation of collagen synthesis and down-regulation of ribosome, oxidative metabolism and mitochondrial gene transcripts following BR in the CON group. Alterations to these gene transcripts were significantly blunted in the HMB group. Mitochondrial respiration and markers of content were both reduced and H₂O₂ emission was elevated in both groups following BR.

Conclusions

In summary, 10 days of BR in older adults causes a significant deterioration in mitochondrial energetics, while transcriptomic profiling revealed that some of these negative effects may be attenuated by an ONS containing HMB.

The effect of short-term exercise prehabilitation on skeletal muscle protein synthesis and atrophy during bed rest in older men

BACKGROUND

Poor recovery from periods of disuse accelerates age-related muscle loss, predisposing individuals to the development of secondary adverse health outcomes. Exercise prior to disuse (prehabilitation) may prevent muscle deterioration during subsequent unloading. The present study aimed to investigate the effect of short-term resistance exercise training (RET) prehabilitation on muscle morphology and regulatory mechanisms during 5 days of bed rest in older men.

METHODS

Ten healthy older men aged 65-80 years underwent four bouts of high-volume unilateral leg RET over 7 days prior to 5 days of inpatient bed rest. Physical activity and step-count were monitored over the course of RET prehabilitation and bed rest, whilst dietary intake was recorded throughout. Prior to and following bed rest, quadriceps cross-sectional area (CSA), and hormone/lipid profiles were determined. Serial muscle biopsies and dual-stable isotope tracers were used to determine integrated myofibrillar protein synthesis (iMyoPS) over RET prehabilitation and bed rest phases, and acute postabsorptive and postprandial myofibrillar protein synthesis (aMyoPS) rates at the end of bed rest.

RESULTS

During bed rest, daily step-count and light and moderate physical activity time decreased, whilst sedentary time increased when compared with habitual levels (P < 0.001 for all). Dietary protein and fibre intake during bed rest were lower than habitual values (P < 0.01 for both). iMyoPS rates were significantly greater in the exercised leg (EX) compared with the non-exercised control leg (CTL) over prehabilitation (1.76 ± 0.37%/day vs. 1.36 ± 0.18%/day, respectively; P = 0.007). iMyoPS rates decreased similarly in EX and CTL during bed rest (CTL, 1.07 ± 0.22%/day; EX, 1.30 ± 0.38%/day; P = 0.037 and 0.002, respectively). Postprandial aMyoPS rates increased above postabsorptive values in EX only (P = 0.018), with no difference in delta postprandial aMyoPS stimulation between legs. Quadriceps CSA at 40%, 60%, and 80% of muscle length decreased significantly in EX and CTL over bed rest (0.69%, 3.5%, and 2.8%, respectively; P < 0.01 for all), with no differences between legs. No differences in fibre-type CSA were observed between legs or with bed rest. Plasma insulin and serum lipids did not change with bed rest.

CONCLUSIONS

Short-term resistance exercise prehabilitation augmented iMyoPS rates in older men but did not offset the relative decline in iMyoPS and muscle mass during bed rest.

Factors Associated with Duration of Rehabilitation Among Older Adults with Prolonged Hospitalization

BACKGROUND/OBJECTIVES

Older adults are prone to functional decline during prolonged hospitalization. Although rehabilitation therapy is critical to preserving function, little is known about rehabilitation duration (RD) in this population. We sought to determine the extent of rehabilitation therapy provided to older adults during prolonged hospitalization, and whether this differs by sociodemographic and clinical characteristics.

DESIGN

Retrospective cohort.

SETTING

Single-site safety-net hospital.

PARTICIPANTS

Older adults (≥65 years) hospitalized for ≥14 days between 2016 and 2017.

MEASUREMENTS

The primary outcome was RD, defined as the average number of minutes of physical and occupational therapy per week. We used a multivariable generalized linear model to assess for differences in RD by sociodemographic and clinical characteristics. For a sub-cohort of hospitalizations with a baseline mobility assessment, we repeated analyses including mobility limitation as a covariate.

RESULTS

Among 1,031 hospitalizations by 925 unique patients (median age 72, 49% female, 79% non-white, 40% non-English speaking), the median RD was 61.3 minutes/week (interquartile range = 16.5-127.3). Covariates associated with lesser RD included black (57.2 fewer minutes/week; 95% confidence interval (CI) = 22.9-91.4) and Hispanic (75.6 fewer minutes/week; 95% CI = 33.8-117.4) race/ethnicity, speaking a language other than English or Spanish (51.7 fewer minutes/week; 95% CI = 21.3-82.0), prolonged mechanical ventilation (30.0 fewer minutes/week; 95% CI = 6.6-53.3), and do-not-resuscitate code status (36.0 fewer minutes/week; 95% CI = 17.1-54.8). The inclusion of mobility limitation among the sub-cohort (n = 350) did not meaningfully change the associations.

CONCLUSION

We found large disparities in RD for racial/ethnic and language minorities and clinically vulnerable older adults (mechanical ventilation and do-not-resuscitate code status), independent of clinical severity and functional and cognitive impairment. Greater RD for these groups may improve functional outcomes and narrow the disparity gap.

Debility Risk Model as a Predictor for Postsurgical Outcomes

BACKGROUND

Decreased patient functional status is associated with higher rates of postoperative morbidity and mortality. The Vizient program recently implemented a debility risk model to identify patients with impaired functional status. We examined the relationship between this novel model and inpatient postsurgical outcomes in a large urban tertiary care center.

METHODS

The Vizient database was accessed to compare surgical outcomes between patients coded with debility and patients without debility between January 2017 and December 2018. Data for each surgical specialty were obtained, and a chi-squared analysis was used to detect differences in readmission rates, mortality, and postoperative complications (defined by Vizient). These complications include pneumonia, postoperative infection, anesthesia complications, and shock.

RESULTS

We found patients with debility have a higher mortality rate (3%) than patients without debility (2%) across all surgical specialties (P = .0103). Patients with debility have a higher 30-day readmission rate (16%) than those without debility (8%) across all specialties (P < .0001). Patients with debility had a higher rate of inpatient complications for neurosurgery (12.11% vs. 8%, P = .008), trauma surgery (11.9% vs. 6%, P =.025), general surgery (17.67% vs. 7%, P = .013), and cardiac surgery (47.06% vs. 18%, P =.0025).

CONCLUSIONS

Our study supports the use of the Vizient debility code to predict postsurgical outcomes and risk stratify patients. By extension, functional status assessments in preoperative evaluation of patients remain important. Further, studies can build upon this data to measure the impact of preoperative, outpatient debility assessments in surgical patients.

Persistent Functional Decline Following Hospitalization with Influenza or Acute Respiratory Illness

Background/objectives

Influenza is associated with significant morbidity and mortality, particularly for older adults. Persistent functional decline following hospitalization has important impacts on older adults' wellbeing and independence, but has been under‐studied in relation to influenza. We aimed to investigate persistent functional change in older adults admitted to hospital with influenza and other acute respiratory illness (ARI).

Design

Protective observational cohort study.

Setting

Canadian Immunization Research Network Serious Outcomes Surveillance Network 2011 to 2012 influenza season.

Participants

A total of 925 patients aged 65 and older admitted to hospital with influenza and other ARI.

Measurements

Influenza was laboratory‐confirmed. Frailty was measured using a Frailty index (FI). Functional status was measured using the Barthel index (BI); moderate persistent functional decline was defined as a clinically meaningful loss of ≥10 to <20 points on the 100‐point BI. Catastrophic disability (CD) was defined as a loss of ≥20 points, equivalent to full loss of independence in two basic activities of daily living.

Results

Five hundred and nineteen (56.1%) were women; mean age was 79.4 (standard deviation=8.4) years. Three hundred and forty‐six (37.4%) had laboratory‐confirmed influenza. Influenza cases had lower baseline function (BI = 77.0 vs 86.9, P < .001) and higher frailty (FI = 0.23 vs 0.20, P < .001) than those with other ARI. A total of 8.4% died, 8.2% experienced persistent moderate functional decline, and 9.9% experienced CD. Higher baseline frailty was associated with increased odds of experiencing functional decline, CD, and death. The experience of functional decline and CD, and its association with frailty, was the same for influenza and other ARI.

Conclusion

Functional loss in hospital is common among older adults; for some this functional loss is persistent and catastrophic. This highlights the importance of prevention and optimal management of acute declines in health, including influenza, to avoid hospitalization. In the case of influenza, for which vaccines exist, this raises the potential of vaccine preventable disability.

Functional decline in geriatric rehabilitation ward; is it ascribable to hospital acquired infection? A prospective cohort study

BACKGROUND

In some European countries, including France, older patients with functional decline in acute units are transferred to geriatric rehabilitation units. Some patients may not benefit from their stay in a geriatric rehabilitation unit and paradoxically worsened their functional status. Previous prognostic models of functional decline are based on only baseline parameters. However, some events can occur during rehabilitation and modify the association between baseline parameters and rehabilitation performance such as heart failure episode, falls or hospital-acquired infection (HAI). The incidence of functional decline in these units and factors associated with this decline have not been clearly identified.

METHODS

We used a prospective cohort of consecutive patients aged ≥75 years admitted to a geriatric rehabilitation unit in a French university hospital. The main endpoint was functional decline defined by at least an one-point decrease in Activities of Daily Living (ADL) score during the stay. Baseline social and geriatric characteristics were recorded and comorbidities were sought by the Cumulative Illness Rating Scale for Geriatrics (CIRS-G). During follow-up, hospital-acquired infection (HAI) was recorded, as was ADL score at discharge. Multivariate logistic regression and mediation analyses were used to identify factors associated with ADL decrease.

RESULTS

Among the 252 eligible patients, 160 (median age 84 years [interquartile range (IQR) 80-88] had available ADL scores at baseline (median score 7 [IQR 4-10]) and at discharge (median 9 [6-12]). Median CIRS-G score was 11 [8-13], 23 (14%) had a pulmonary HAI; 28 (17.5%) showed functional decline. On multivariable analysis, functional decline was associated with comorbidities (global CIRS-G score, P = 0.02, CIRS-G for respiratory disease [CIRS-G-R] ≥2, P = 0.02, or psychiatric disease, P = 0.02) and albumin level < 35 g/l (p = 0.03). Significant associations were found between functional decline and CIRS-G-R (OR 3.07 [95%CI 1.27-7.41], p = 0.01), between functional decline and pulmonary HAI (OR 3.12 [1.17-8.32],p = 0.02), and between CIRS-G-R and pulmonary HAI (OR 12.9[4.4-37.7], p = 0.0001). Theses associations and the reduced effect of CIRS-G-R on functional decline after adjusting for pulmonary HAI (OR 2.26 [0.83-6.16], p = 0.11) suggested partial mediation of pulmonary HAI in the relation between CIRS-G-R and functional decline.

CONCLUSION

Baseline comorbidities were independently associated with functional decline in patients hospitalized in a geriatric rehabilitation unit. Pulmonary HAI may have mediated this association. We need to better identify patients at risk of functional decline before transfer to a rehabilitation unit and to test the implementation of modern and individual programs of rehabilitation outside the hospital for these patients.

A novel early mobility bundle improves length of stay and rates of readmission among hospitalized general medicine patients

Inpatient early mobility initiatives are effective therapeutic interventions for improving patient outcomes and decreasing use of hospital resources among adult ICU and general medicine patients. To establish and demonstrate guidelines for early patient ambulation, we developed and implemented a novel multidisciplinary mobility bundle utilizing the JH-HLM (Johns Hopkins Highest Level of Mobility) scale for mobility classification, on a single adult general medicine unit of a community hospital. Our results show that patients admitted to the unit after implementation of the mobility bundle had improved mobility scores, reduced rates of 30-day hospital readmission, and a shortened length of hospital stay. This study emphasizes the importance of measuring mobility using a systematic method, easing workflow among unit practitioners, and allowing mobility initiatives to be jointly driven by nursing, physical therapy, and physicians.

Concurrent Validity, Test-Retest Reliability, and Sensitivity to Change of a Single Body-Fixed Sensor for Gait Analysis during Rollator-Assisted Walking in Acute Geriatric Patients

Body-fixed sensor (BFS) technology offers portable, low-cost and easy-to-use alternatives to laboratory-bound equipment for analyzing an individual's gait. Psychometric properties of single BFS systems for gait analysis in older adults who require a rollator for walking are, however, unknown. The study's aim was to evaluate the concurrent validity, test-retest-reliability, and sensitivity to change of a BFS (DynaPort MoveTest; McRoberts B.V., The Hague, The Netherlands) for measuring gait parameters during rollator-assisted walking. Fifty-eight acutely hospitalized older patients equipped with the BFS at the lower back completed a 10 m walkway using a rollator. Concurrent validity was assessed against the Mobility Lab (APDM Inc.; Portland, OR, USA), test-retest reliability over two trials within a 15 min period, and sensitivity to change in patients with improved, stable and worsened 4 m usual gait speed over hospital stay. Bland-Altman plots and intraclass correlation coefficients (ICC) for gait speed, cadence, step length, step time, and walk ratio indicate good to excellent agreement between the BFS and the Mobility Lab (ICC_2,1 = 0.87-0.99) and the repeated trials (ICC_2,1 = 0.83-0.92). Moderate to large standardized response means were observed in improved (gait speed, cadence, step length, walk ratio: 0.62-0.99) and worsened patients (gait speed, cadence, step time: -0.52 to -0.85), while those in stable patients were trivial to small (all gait parameters: -0.04-0.40). The BFS appears to be a valid, reliable and sensitive instrument for measuring spatio-temporal gait parameters during rollator-assisted walking in geriatric patients.

Prehospital and Posthospital Fall Injuries in Older US Adults

IMPORTANCE

To date, measurement and treatment of older adult fall injury has been siloed within specific care settings, such as a hospital or within a nursing home or community. Little is known about changes in fall risk across care settings. Understanding the occurrence of falls across settings has implications for measuring and incentivizing high-value care across care settings.

OBJECTIVE

To estimate the risk of older adult fall injury within and across discrete periods during a 12-month care episode anchored by an acute hospitalization.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study is a longitudinal analysis of 12-month periods that include an anchor hospital stay using national data from 2006 to 2014. Participants included older (aged ≥65 years) Medicare fee-for-service beneficiaries from the Health and Retirement Study. Weekly fall injury rates were computed for 4 periods compared with the anchor hospitalization: at baseline (1-6 months before hospitalization), just before (<1 month before hospitalization), just after (<1 month after hospitalization), and at follow-up (1-6 months after hospitalization). Piecewise logistic regression models estimated weekly marginal risk of fall injury within each period, adjusting for sociodemographic and health characteristics. Fall injury risks for high-risk beneficiaries with a fall injury during the anchor hospitalization were also estimated. Data analysis was performed from November 2019 to April 2020.

MAIN OUTCOMES AND MEASURES

Fall injuries.

RESULTS

In total, 10 106 anchor hospitalizations for 4101 beneficiaries (mean [SD] age, 77.1 [7.6] years; 5912 hospitalizations among women [58.5%]) were identified. The overall fall injury risk was 0.77%. In adjusted models, marginal increases in weekly fall injury risk just before hospitalization (0.27 percentage points [95% CI, 0.22 to 0.33 percentage points], or 30.0%; P < .001) were 4 times greater than decreases just after hospitalization (-0.18 percentage points [95% CI, -0.23 to -0.13 percentage points], or -9.2%; P < .001)]. A greater risk differential before and after hospitalization was observed for patients with an inpatient fall injury (1.89 percentage points [95% CI, 1.37 to 2.40], or 309.8%; P < .001; vs -0.39 percentage points [95% CI, -0.73 to -0.04], or -11.6%; P = .03).

CONCLUSIONS AND RELEVANCE

An episode-based assessment of fall injury illustrates substantial variability in period-specific risks over an extended period including an anchor hospitalization. Risk transitions between periods include sizable increases just before hospitalization that do not fully subside after hospital discharge. Financial incentives to coordinate hospital and posthospital care for patients at risk for fall injury are needed. These could include bundled payments for fall injury episodes that incentivize coordination across settings.
