Hospitalization and development of dependence in activities of daily living in a cohort of disabled older women: the Women's Health and Aging Study I

Mobility Loss in Hospitalized Adults Predicts Poor Clinical Outcomes

BACKGROUND

The Johns Hopkins Activity and Mobility Program is a systematic approach to measure and improve patient mobility.

PURPOSE

The purpose of this study was to evaluate the relationship between mobility loss and quality outcomes.

METHODS

A retrospective cohort study design was used. Patients were categorized into 3 groups (gain, loss, no change in mobility) using the Johns Hopkins Highest Level of Mobility (JH-HLM) scores. The association between mobility loss and falls risk, in-hospital mortality, delirium, discharge to a facility, length of stay, and 30 day readmissions were assessed.

RESULTS

Those who lost mobility were more at risk of being a high fall risk, in-hospital mortality, delirium, discharging to a facility, and had 48% longer lengths of stay. There was no association between mobility loss and 30-day readmissions.

CONCLUSIONS

Loss of mobility assessed using JH-HLM scores is associated with worse patient outcomes.

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.

Improvements in sleep quality and fatigue are associated with improvements in functional recovery following hospitalization in older adults

Study objectives

Poor sleep quality, a frequent problem in older adults, has been shown to be associated with reduced physical function and wellbeing. However, little is known about the relationship between sleep quality and the recovery of physical function following hospitalization. Thus, we conducted this study to examine the association between sleep quality and functional recovery after an acute hospitalization in community dwelling older adults.

Methods

Older adult patients (N = 23, mean age = 74 ± 9 years) were recruited during an acute hospitalization (average length of stay 3.9 days) with a cardiovascular (56%), pulmonary (22%), or metabolic (13%) admission diagnosis. Objective physical function was measured using the Short Physical Performance Battery (SPPB) and self-reported function was assessed with Katz Index of Independence in Activities of Daily Living (ADL) and Lawton Instrumental Activities of Daily Living Scale (IADL). Sleep quality was measured using Pittsburgh Sleep Quality Index (PSQI) global score and Iowa Fatigue Score (IFS). Testing was performed prior to discharge (baseline) and 4-weeks post-discharge (follow-up).

Results

Regression models showed PSQI Subjective Sleep Quality change scores from baseline to 4-week follow-up predicted a change in ADL (β = -0.22); PSQI Use of Sleep Medications change scores predicted a change in SPPB Total (β = 1.62) and SPPB Chair Stand (β = 0.63); IFS change scores predicted SPPB Total (β = -0.16) and SPPB Chair Stand performance (β = -0.07) change scores.

Conclusions

For older adults, changes in sleep medication use, daytime dysfunction, and fatigue were associated with improvements in functional recovery (including physical performance and independence) from acute hospitalization to 4-week follow-up. These results suggest that interventions focused on improving sleep quality, daytime consequences, and fatigue might help enhance physical functioning following hospitalization.

Impact of Exercise Intervention-Based Changes on Physical Function Biomarkers in Older Adults After Hospital Discharge: A Systematic Review with Meta-Analysis of Randomized Clinical Trials

BACKGROUND

This systematic review with meta-analysis aimed to compare the changes caused by exercise interventions with those provoked by usual care on physical function biomarkers in older adults immediately after hospital discharge.

METHODS

Two independent authors performed a systematic search (PubMed, Scopus, Web of Science, and SciELO) of studies published from database inception until August 2021. Randomized clinical trials investigating the effects of an exercise intervention compared to usual care were included. The Cochrane Collaboration assessment tool was used to analyze the risk of bias. The comparisons included handgrip strength, the short physical performance battery scale, six-minute walking test, and 10-m gait speed.

RESULTS

Overall, the exercise intervention led to significantly greater changes compared to usual care in physical function biomarkers [standard mean difference = 0.89, 95% CI = 0.39, 1.42; P = 0.001]. However, considering the very few studies investigating each variable separately, our sub-analysis did not reveal a significant effect of the exercise intervention on handgrip strength, the short physical performance battery, six minutes walking test, and 10-m gait speed.

CONCLUSIONS

This systematic review with meta-analysis of randomized clinical trials suggests that exercise interventions after hospital discharge induce greater physical function biomarker alterations in older adults after hospitalization than usual care including physical activity guidance. Future trials comparing the effects of these intervention groups on physical function biomarkers in this population are needed to confirm our results.

Insight Into the Posthospital Syndrome: A 3-Month Longitudinal Follow up on Geriatric Syndromes and Their Association With Functional Decline, Readmission, and Mortality

Background

Acute hospitalization may lead to posthospital syndrome, but no studies have investigated how this syndrome manifests and geriatric syndromes are often used as synonym. However, studies on longitudinal associations between syndromes and adverse outcomes are scarce. We aimed to analyze longitudinal associations between geriatric syndromes and functional decline (FD), readmission, and mortality.

Methods

Prospective cohort study, including 401 acutely hospitalized patients (aged ≥ 70). We performed: (i) logistic regression analyses to assess associations between patterns of geriatric syndromes as they develop over time (between admission and 1 month postdischarge), and FD and readmission; (ii) generalized estimating equations to assess longitudinal associations between geriatric syndromes over five time points (admission, discharge, 1, 2, and 3 months postdischarge) and FD, mortality, and readmission at 3 months postdischarge.

Results

After syndrome absent, syndrome present at both admission and 1 month postdischarge was most prevalent. Persistent patterns of apathy (odds ratio [OR] = 4.35, 95% confidence interval [CI] = 1.54–12.30), pain (OR = 3.26, 95% CI = 1.21–8.8), malnutrition (OR = 3.4, 95% CI = 1.35–8.56), mobility impairment (OR = 6.65, 95% CI = 1.98–22.38), and fear of falling (OR = 3.17, 95% CI = 1.25–8.02) were associated with FD. Developing cognitive impairment (OR = 6.40, 95% CI = 1.52–26.84), fatigue (OR = 4.71, 95% CI = 1.03–21.60), and fall risk (OR = 4.30, 95% CI = 1.21–16.57) postdischarge, was associated with readmission; however, only 4%–6% developed these syndromes. Over the course of five time points, mobility impairment, apathy, and incontinence were longitudinally associated with FD; apathy, malnutrition, fatigue, and fall risk with mortality; malnutrition with readmission.

Conclusion

Most geriatric syndromes are present at admission and patients are likely to retain them postdischarge. Several geriatric syndromes are longitudinally associated with mortality and, particularly, persistently present syndromes place persons are at risk of FD. Although few persons develop syndromes postdischarge, those developing cognitive impairment, fatigue, and fall risk were at increased readmission risk.

Hospitalization-Associated Change in Gait Speed and Risk of Functional Limitations for Older Adults

BACKGROUND

Hospitalization-associated functional decline is a common problem for older adults, but it is unclear how hospitalizations affect physical performance measures such as gait speed. We sought to determine hospitalization-associated change in gait speed and likelihood of new limitations in mobility and activities of daily living (ADLs).

METHODS

We used longitudinal data over 5 years from the Health, Aging and Body Composition Study, a prospective cohort of black and white community-dwelling men and women, aged 70-79 years, who had no limitations in mobility (difficulty walking 1/4 mile or climbing 10 steps) or ADLs (transferring, bathing, dressing, and eating) at baseline. Gait speed, and new self-reported limitations in mobility and ADLs were assessed annually. Selected participants (n = 2,963) had no limitations at the beginning of each 1-year interval. Hospitalizations were self-reported every 6 months and verified with medical record data. Generalized estimating equations were used to examine hospitalization-associated change in gait speed and odds of new limitations over each 1-year interval. Fully adjusted models included demographics, hospitalization within the past year, health conditions, symptoms, body mass index, and health-related behaviors.

RESULTS

In fully adjusted models, any hospitalization was associated with decrease in gait speed (-0.04 m/s; 95% confidence interval [CI]: -0.05 to -0.03) and higher odds of new limitations in mobility or ADLs (odds ratio = 1.97, 95% CI: 1.70-2.28), and separately with increased odds of new mobility limitation (odds ratio = 2.22, 95% CI: 1.90-2.60) and new ADL limitations (odds ratio = 1.84, 95% CI: 1.53-2.21). Multiple hospitalizations within a year were associated with gait speed decline (-0.06 m/s; 95% CI: -0.08 to -0.04) and greater odds of new limitations in mobility or ADLs (odds ratio = 2.96, 95% CI: 2.23-3.95).

CONCLUSIONS

Functionally independent older adults experienced hospitalization-associated declines in gait speed and new limitations in mobility and ADLs.

Assessment of Mobility in Older People Hospitalized for Medical Illness Using the de Morton Mobility Index and Cumulated Ambulation Score-Validity and Minimal Clinical Important Difference

Background and Purpose:

Older adults acutely hospitalized for medical illness typically have comorbidity and disability, and in-hospital physical inactivity greatly increases the likelihood of developing new disability. Thus, assessment of the patients' mobility status is crucial for planning and carrying out targeted interventions that ensure mobilization during hospital admission. The aim of this study was to determine convergent validity, known group validity, floor and ceiling effects, and anchor-based minimal clinically important difference (MCID) of the more time-consuming de Morton Mobility Index (DEMMI) and the less time-consuming Cumulated Ambulation Score (CAS) in older adults acutely hospitalized for medical illness.

Methods:

In this multicenter cohort study, 235 older hospitalized adults, with a mean (standard deviation) age of 84.8 (7.1) years, were consecutively included. Assessments of mobility using the DEMMI (score range 0-100), the CAS (score range 0-6), and the Barthel Index (BI, score range 0-100) were performed by physical or occupational therapists at hospital admission and discharge. In addition, at discharge patients and therapists were independently asked to assess the patients' current mobility status compared with their mobility status at hospital admission using the Global Rating of Change scale.

Results and Discussion:

Complete data sets were obtained for 155 patients. Baseline characteristics of those with complete data sets did not differ from those with incomplete data sets, except for the number of secondary diagnoses, which was lower in the latter. Significant and moderate relationships existed both at admission and at discharge between scores in the DEMMI and the BI (r_s = 0.68, P < .0001, and r_s = 0.71, P < .0001), and between scores in the CAS and the BI (r_s = 0.60, P < .0001, and r_s = 0.57, P < .0001). Use of a gait aid and discharge to inpatient rehabilitation or nursing home were associated with significantly lower DEMMI and CAS scores. No floor or ceiling effects were present in the DEMMI, while a ceiling effect was present in the CAS. The MCID scores based on patients' assessments were 10.7 points for the DEMMI and 0.67 for the CAS.

Conclusions:

These data show that the DEMMI is valid and responsive to changes in mobility and can be considered to have the required properties for measuring mobility in older adults who are hospitalized in medical and geriatric wards. In contrast, the CAS appears to be appropriate to identify whether a patient is independently mobile or needs assistance, while the measure is less suitable for measuring improvements in mobility.

Investigating the effectiveness of care delivery at an acute geriatric community hospital for older adults in the Netherlands: a protocol for a prospective controlled observational study

INTRODUCTION

Hospital admission in older adults with multiple chronic conditions is associated with unwanted outcomes like readmission, institutionalisation, functional decline and mortality. Providing acute care in the community and integrating effective components of care models might lead to a reduction in negative outcomes. Recently, the first geriatrician-led Acute Geriatric Community Hospital (AGCH) was introduced in the Netherlands. Care at the AGCH is focused on the treatment of acute diseases, comprehensive geriatric assessment, setting patient-led goals, early rehabilitation and streamlined transitions of care.

METHODS AND ANALYSIS

This prospective cohort study will investigate the effectiveness of care delivery at the AGCH on patient outcomes by comparing AGCH patients to two historic cohorts of hospitalised patients. Propensity score matching will correct for potential population differences. The primary outcome is the 3-month unplanned readmission rate. Secondary outcomes include functional decline, institutionalisation, healthcare utilisation, occurrence of delirium or falls, health-related quality of life, mortality and patient satisfaction. Measurements will be conducted at admission, discharge and 1, 3 and 6 months after discharge. Furthermore, an economic evaluation and qualitative process evaluation to assess facilitators and barriers to implementation are planned.

ETHICS AND DISSEMINATION

The study will be conducted according to the Declaration of Helsinki. The Medical Ethics Research Committee confirmed that the Medical Research Involving Human Subjects Act did not apply to this research project and official approval was not required. The findings of this study will be disseminated through public lectures, scientific conferences and journal publications. Furthermore, the findings of this study will aid in the implementation and financing of this concept (inter)nationally.

ADL recovery trajectory after discharge and its predictors among baseline-independent older inpatients

Background

Among the previous studies about the ADL recovery and its predictors, the researches and resources used to study and protect the baseline-independent older patients from being permanently ADL-dependent was few. We aimed to describe the level of activities of daily living (ADL) at discharge and ADL change within 6 months after discharge in older patients who were ADL-independent before admission but became dependent because of acute illness, and to identify the predictors of early rehabilitation,so as to provide the basis to early intervention.

Methods

Stratified cluster sampling was used to recruit 520 hospitalised older patients who were ADL-independent from departments of internal medicine at two tertiary hospitals from August 2017 to May 2018. Demographics, clinical data, and ADL status at 1, 3, and 6 months after discharge were collected. Data were analysed using descriptive statistics, Student’s t-test, Pearson’s chi-square test,Spearman’s correlation analysis, binary logistic regression analysis, and receiver operating characteristic (ROC) curve analysis.

Results

There were 403 out of 520 patients completing the 6-month follow-up, and 229 (56.8%) regained independence at 6 months after discharge. There was an overall increasing trend in ADL with time. The recovery rate was the highest within the first month after discharge, gradually declined after 1 month, and changed less obviously from 3 to 6 months after discharge (p < 0.001). ADL score at discharge (OR = 1.034, p < 0.001), age (OR = 0.269, p = 0.001), post-discharge residence (OR = 0.390, p < 0.05), and cognition status at discharge (OR = 1.685, p < 0.05) were predictors of ADL recovery. The area under the curve of the four predictors combined was 0.763 (p < 0.001).

Conclusion

Studying ADL recovery rate and its predicting indicators of the baseline independent inpatients at different time points provide a theoretical reference for the formulation of nursing plans and allocation of care resources.

Length of hospital stay is associated with a decline in activities of daily living in hemodialysis patients: a prospective cohort study

Background

The impact of length of hospital stay on activities of daily living (ADLs) has not specifically been investigated among dialysis patients. Therefore, we attempt to verify the association between the length of hospital stay and the decline in ADLs among hemodialysis patients.

Methods

This prospective cohort study used data from the Japanese Dialysis Outcomes and Practice Patterns Study (J-DOPPS). We included 2442 hemodialysis patients aged ≥40 years from the J-DOPPS phase V (2012–2015) and subsequently excluded those who had already lost basic activities of daily living (BADLs) as demonstrated by dependency in at least three of the five BADLs at baseline and for whom changes in ADLs had been evaluated for less than 90 days. The main exposure was the cumulative length of hospital stay during the follow-up period. The primary outcomes were a decline in at least one of the five BADLs and eight instrumental activities of daily living (IADLs). We compared risk ratios (RRs) for 30-day increments for hospital stays with 10-year increments for age and having diabetes.

Results

A total of 849 patients were included in the statistical analysis. The cumulative length of hospital stay was significantly associated with a risk of decline in ADLs (adjusted RRs [95% confidence intervals] per 30-day increments: 1.42 [1.15 to 1.75] for BADLs, 1.38 [1.13 to 1.68] for IADLs). The adjusted RRs [95% CI] for 10-year increments in age were 1.20 [0.96 to 1.50] and 1.21 [1.00 to 1.47]. The adjusted RRs [95% CI] for having diabetes were 1.36 [0.97 to 1.91] for BADLs and 1.38 [1.04 to 1.84] for IADLs.

Conclusion

The impact of a 30-day increment in the cumulative length of hospital stay on the decline in ADLs was comparable to that of a 10-year increase in age and having diabetes.

Frailty and Cause-Specific Hospitalizations in Community-Dwelling Older Men

OBJECTIVES

The types of medical conditions leading to hospitalization in frail older people have not been investigated. The objectives were to evaluate associations between frailty and (a) risk of all-cause and cause-specific hospitalization, and (b) rate of all-cause and cause-specific hospitalizations.

DESIGN, SETTING AND PARTICIPANTS

Community-dwelling men aged 70+ years in the Concord Health and Ageing in Men Project (CHAMP) were assessed for frailty at baseline (2005-2007, n=1705).

MEASUREMENTS

Frailty was determined by both the Fried frailty phenotype (FP) and the Rockwood frailty index (FI). Non-elective and elective hospitalization data were accessed from the New South Wales (NSW) Admitted Patient Data Collection and mortality from the NSW Deaths Registry for the period 2005-2017. Causes of hospitalization were categorized using ICD-10 classification of principal diagnoses based on organ system involved into 14 major categories.

RESULTS

Nearly 80% of CHAMP men had at least one non-elective hospitalization and 63% had an elective hospitalization over a 9-year follow-up. Men with FP frailty were twice as likely to have a non-elective hospitalization (HR: 1.98, 95%CI: 1.61-2.44) and a greater number of non-elective hospitalizations (IRR: 1.44, 95%CI: 1.22-1.70). Similar relationships were found between FI frailty and non-elective hospitalizations. Men with frailty (either FP or FI) were more likely to have at least one non-elective hospitalization for 13 of the 14 cause-related admissions. In contrast, frailty was only associated with 3 cause-related elective hospitalizations. Men with frailty were also more likely to have an increased number of non-elective hospitalizations for all 14 causes, but only for 6 causes of elective hospitalizations.

CONCLUSIONS

Our findings suggest frailty increases the risk and number of non-elective hospitalizations in older men for a wide range of cause. Strategies on early identification of frailty, followed by appropriate preventative strategies to lower the risk of non-elective hospital admissions are warranted.

Differences in function and recovery profiles between patterns of multimorbidity among older medical patients the first year after an acute admission-An exploratory latent class analysis

INTRODUCTION

Multimorbidity is common among older people and may contribute to adverse health effects, such as functional limitations. It may help stratify rehabilitation of older medical patients, if we can identify differences in function under and after an acute medical admission, among patient with different patterns of multimorbidity.

AIM

To investigate differences in function and recovery profiles among older medical patients with different patterns of multimorbidity the first year after an acute admission.

METHODS

Longitudinal prospective cohort study of 369 medical patients (77.9 years, 62% women) acutely admitted to the Emergency Department. During the first 24 h after admission, one month and one year after discharge we assessed mobility level using the de Morton Mobility Index. At baseline and one-year we assessed handgrip strength, gait speed, Barthel20, and the New Mobility Score. Information about chronic conditions was collected by national registers. We used Latent Class Analysis to determine differences among patterns of multimorbidity based on 22 chronic conditions.

RESULTS

Four distinct patterns of multimorbidity were identified (Minimal chronic disease; Degenerative, lifestyle, and mental disorders; Neurological, functional and sensory disorders; and Metabolic, pulmonary and cardiovascular disorders). The "Neurological, functional and sensory disorders"-pattern showed significant lower function than the "Minimal chronic disease"-pattern in all outcome measures. There were no differences in recovery profile between patients in the four patterns.

CONCLUSION

The results support that patients with different patterns of multimorbidity among acutely hospitalized older medical patients differ in function, which suggests a differentiated approach towards treatment and rehabilitation warrants further studies.

The dose of physical activity to minimise functional decline in older general medical patients receiving 24-hr acute care: A systematic scoping review

AIMS AND OBJECTIVES

To identify evidence for a recommended and feasible activity dose to minimise functional decline in older hospitalised general medical patients.

BACKGROUND

Quality 24-hr care of older patients involves balancing activity to minimise functional decline, with rest to aid recovery. However, there is limited guidance regarding an optimal type and dose of activity to minimise functional decline in hospitalised elders receiving acute medical care.

DESIGN

A systematic search and scoping review of the literature were conducted following Joanna Briggs methodological guidance.

METHODS

The results were reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Study bias was determined using the Joanna Briggs Institute Critical Appraisal Tools.

RESULTS

Fifteen primary studies of variable design, rigour and potential for bias were included. Study contexts were general medical wards (n = 11, 73.3%), Acute care of the elderly unit (n = 3, 20%) and a nursing unit (n = 1, 6.7%) located in tertiary referral acute hospitals. Most participants were aged 75-84 years (n = 10, 66%), had variable medical diagnoses and samples were either physically capable (n = 4, 26.7%) of limited physical capability (n = 1, 6.7%) or of mixed capability to mobilise independently (n = 10, 66.7%). Walking at least twice a day for approximately 20 min in total appeared to be associated with less functional decline in older patients of variable physical capabilities, and the overall efficacy of twice-daily exercise to reduce functional decline was supported.

CONCLUSION

The evidence tentatively supported walking for hospitalised elders, irrespective of physical capability, and based on one RCT, suggested likely benefits of graduated exercise in dependent elders. Insufficient evidence limits prescription of optimal doses of physical activity to minimise functional decline.

RELEVANCE TO CLINICAL PRACTICE

This review could provide evidence for nurses to promote function in older patients by specifying a dose of physical activity to be undertaken in hospital.

The Effect of Foot Reflexology on Hospital Anxiety and Depression in Female Older Adults: a Randomized Controlled Trial

BACKGROUND

Patients with cardiovascular diseases usually suffer from hospital anxiety and depression.

AIM

This study aimed to investigate the effect of foot reflexology massage on anxiety and depression in female older adults suffering from acute coronary syndrome.

PARTICIPANTS

Ninety older women with acute coronary syndrome were randomly assigned into intervention and control groups (n=45 in each group).

RESEARCH DESIGN

A randomized controlled trial.

INTERVENTION

The intervention and control groups received foot reflexology massage and routine care, respectively.

MAIN OUTCOMES MEASURES

The levels of anxiety and depression were evaluated using the hospital's anxiety and depression scale (HADS) before and immediately after foot reflexology massage.

RESULTS

Foot reflexology massage reduced both anxiety (F(1.44)=19.11, p = .001) and depression (F(1.44)=16.76, p = .001) in acute coronary patients relative to control patients. The intervention had a large effect on hospital anxiety and depression.

CONCLUSIONS

Foot reflexology massage is an efficient and safe intervention for alleviating psychological responses among female older adults suffering from acute coronary syndrome during hospitalization.

Quantifying physical functional trajectory in hospitalized older adults using body worn inertial sensors

Acute medical illness requiring hospitalization usually is a critical event in the trajectory leading to disability in older adults. Functional decline frequently occurs during hospitalization, resulting in a loss of Independence in activities of daily living after discharge. The aim of the study was to assess the functional decline in different ADLs of hospitalized elderly patients in an Acute Care for Elderly (ACE) unit incorporating a body-worn inertial sensor and accompanying custom algorithms. 38 hospitalized older adults (age ≥ 75) were included. The patients completed different functional tasks, including a balance test, Gait Velocity Test (GVT), verbal and arithmetic dual-task gait, and a sit-to-stand ability test at admission and discharge. Movement-related parameters were acquired from a unique tri-axial inertial sensor unit. Maximal muscle strength and muscle power output endpoints were also assessed. The results indicated that significant improvements (p < 0.05) were found at discharge compared with the admission values for gait variability and spatiotemporal parameters in the 4- and 6-meter GVT. These significant gains were also obtained in the verbal GVT. In contrast, a significant reduction was found in the functional status measured with the Barthel Index scale. Regarding to the sit-to-stand ability, lower peak power was observed in the sit-to-stand phase of the task at discharge. In conclusion, inertial sensor unit and our custom, validated, algorithms represent a feasible tool for measuring and monitoring functional trajectory during hospitalization in older adults and they are sensitive to detect differences in movement pattern parameters in different ADLs such as walking and the ability to stand from a seated position.

Disentangling the complexity of mobility of older medical patients in routine practice: An ethnographic study in Denmark

AIM

Many older medical patients experience persistent functional limitations after hospitalization, such as dependency in activities of daily living, recurring fall incidents and increased mortality. Therefore, increased activity and mobilization during hospitalization are essential to prevent functional decline in older medical patients. No previous studies have explored how the social context influences how health professionals decide whether or not to mobilize patients. This qualitative study aimed to explore how social contextual circumstances affect the mobility of older medical patients in medical departments.

METHODS

An ethnographic field study was conducted in six medical departments in three public hospitals in the capital region of Copenhagen, Denmark. Participant observations were carried out from January to June 2017. The researchers were present for up to 14 days (range, 8-14 days) in the six departments. A total of 210 pages of field notes were produced. The participants were health professionals involved in the care of older medical patients: physiotherapists, registered nurses, nursing assistants and physicians. A content analysis was conducted.

FINDINGS

Five themes concerning mobility of patients emerged: (1) materialities; (2) professional roles; (3) encouraging moments; (4) patients and relatives; and (5) organization and management. Of these, professional roles seem to be the most important because it pervaded all themes. Different health professionals in the medical departments recognized, spoke and acted based on different cultural models.

CONCLUSION

It was found that mobility of older medical patients is entangled in a complex network of social contextual circumstances. Mobility of older medical patients is based on health professionals' different cultural models, which shape distinct professional identities and lead to contradictions and blurring of the priorities and responsibilities among the health professionals involved in mobilization. The consequence is that no profession "owns" the responsibility for mobilization, thus restricting mobilization of the patients during hospitalization.

Impaired chair-to-bed transfer ability leads to longer hospital stays among elderly patients

Background

The study objectives were to identify the main predictive factors for long hospital stays and to propose new and improved methods of risk assessment.

Methods

This prospective cohort study was conducted in the clinics and surgical wards of a tertiary hospital and involved 523 elderly patients over 60 years of age. Demographic, clinical, functional, and cognitive characteristics assessed between 48 and 72 h after admission were analyzed to investigate correlations with lengths of stay greater than 10 days. Univariate and multivariate analyses were performed, and in the final model, long-term probability scores were estimated for each variable.

Results

Of the 523 patients studied, 33 (6.3%) remained hospitalized for more than 10 days. Multiple regression analysis revealed that both the presence of diabetes and the inability to perform chair-to-bed transfers (Barthel Index) remained significant risk predictors. Diabetes doubled the risk of prolonged hospital stays, while a chair-to-bed transfer score of 0 or 5 led to an eight-fold increase in risk. Conclusions: In this study, we propose an easy method that can be used, after external validation, to screen for long-term risk (using diabetes and bed/chair transfer) as a first step in identifying hospitalized elderly patients who will require comprehensive assessment to guide prevention plans and rehabilitation programs.

Feasibility and effectiveness of home-based exercise programs on physical performance and health-related quality of life of the older people dwelling on an isolated, doctor-less island

AIM

To promote preventive care among older individuals dwelling on an isolated, doctor-less island, we investigated the feasibility and the efficacy of a home-based exercise program, depending on their functional status and health-related quality of life.

METHODS

A total of 23 older (mean age 72.6 years) participants were assigned to a home-based exercise program (intervention group), and 34 older (mean age 74.2 years) participants were assigned to a group without any intervention (control group). The participants of the intervention group attended the exercise program three times a week for 3 months. The exercise program consisted of various exercises involving stretching, muscle strengthening, balance retraining and walking. The physical performance, Functional Independence Measure and Short-Form 36-item health survey were used to assess the physical and the mental wellbeing of the participants.

RESULTS

There was no significant difference between the changes in physical performance at baseline and post 3 months in both groups. However, the motor and the cognitive Functional Independence Measure scores significantly improved in the intervention group post 3 months. The domains of the Short-Form 36-item health survey improved post 3 months; particularly, significant improvement was observed in the physical functions, general health, vitality, mental health and mental component summary.

CONCLUSIONS

Although an isolated island has several problems to support preventive care services, such as a lack of medical resources and availability of only a few healthcare workers, the present study provides evidence on the feasibility and efficacy of nurse-led home-based exercise programs for improving the physical and mental health of the older people dwelling on an isolated, doctor-less island.

A tailored strategy for designing the Walk-Copenhagen (WALK-Cph) intervention to increase mobility in hospitalised older medical patients: a protocol for the qualitative part of the WALK-Cph project

INTRODUCTION

Older medical patients (>65 years) represent 54% of the admissions to Danish medical and emergency departments. Acute admissions and bed-rest during hospitalisation are independent risk factors for death and dependency in older patients. Even short hospitalisations are associated with increased dependency in activities of daily living after discharge. Interventions that increase mobility during hospitalisation are therefore important. The purpose of this protocol is to describe the intervention design of the WALK-Copenhagen project, aimed at increasing 24 hours mobility in older medical patients during acute hospitalisations and following discharge.

METHODS AND ANALYSIS

This study is based on ethnographic fieldwork and interviews. Workshops are used to develop and co-design the intervention in collaboration with key stakeholders (patients, relatives, health professionals and researchers). The theory of cultural learning processes, and the cultural historical activity theory will be used to help us understand the interaction between health professionals, structures and objects in relation to mobility in the medical departments.

ETHICS AND DISSEMINATION

The project will adhere to the directives of the Helsinki Declaration. Ethical approval was not required for the study since formal ethical approval is not mandatory for studies that do not involve biomedical issues (I-Suite no: 05078) according to Danish law. Informed consent was obtained for all participants. The results will be disseminated to health professionals, managers, patients and relatives, who will be invited to afternoon meetings where the project will be discussed. The results will be published in peer-reviewed scientific journals and presented at scientific conferences.

Functional status and annual hospitalization in multimorbid and non-multimorbid older adults: a cross-sectional study in Southern China

Background

Hospitalization over the last one year, an indicator of health service utilization, is an important and costly resource in older adult care. However, data on the relationship between functional status and annual hospitalization among older Chinese people are sparse, particularly for those with and without multimorbidity. In this study,we aimed to examine the association between functional status and annual hospitalization among community-dwelling older adults in Southern China, and to explore the independent contributions of socio-demographic variables, lifestyle and health-related factors and functional status to hospitalization in multimorbid and non-multimorbid groups.

Methods

This cross-sectional, community-based survey, studied 2603 older adults aged 60 years and above. Functional status was assessed by Functional Independence Measure (FIM). The outcome variable was any hospitalization over the last one year (annual hospitalization). Clustered logistic regression was used to analyze the independent contributions of FIM domains to annual hospitalization.

Results

Only in the multimorbid group, did the risk of annual hospitalization decrease significantly with increasing FIM score in walk domain (adjusted OR = 0.80 per SD increase, 95% CI = 0.70–0.91, P = 0.001) and its independent contribution accounted for 24.62%, more than that of socio-demographic variables (18.46%). However, among individuals without multimorbidity, there were no significant associations between FIM domains and annual hospitalization; thus, no independent contribution to the risk of hospitalization was observed.

Conclusions

There exist some degree of correlation between functional status and annual hospitalization among older adults in Southern China, which might be due to the presence of multimorbidity with advanced age.

Identifying Factors Associated With Mobility Decline Among Hospitalized Older Adults

Hospitalization can negatively affect mobility among older adults. Early detection of older patients most at risk for mobility decline can lead to early intervention and prevention of mobility loss. This study's purpose was to identify factors from the International Classification of Functioning, Disability, and Health associated with mobility decline among hospitalized elders. We conducted a secondary analysis of data from 959 hospitalized adults age 65 and older. We estimated the effects of health conditions and environmental and personal factors on mobility decline using logistic regression. Almost half of the sample declined in mobility function during hospitalization. Younger age, longer length of hospital stay, having a hearing impairment, and non-emergency admit type were associated with mobility decline, after adjusting for covariates. Findings may be used to develop an evidence-based, risk-determination tool for hospitalized elders. Future research should focus on individual, environmental, and policy-based interventions promoting physical activity in the hospital.

Age-Related Diseases and Clinical and Public Health Implications for the 85 Years Old and Over Population

By 2050, the American 85 years old and over population will triple. Clinicians and the public health community need to develop a culture of sensitivity to the needs of this population and its subgroups. Sensory changes, cognitive changes, and weakness may be subtle or may be severe in the heterogeneous population of people over age 85. Falls, cardiovascular disease, and difficulty with activities of daily living are common but not universal. This paper reviews relevant changes of normal aging, diseases, and syndromes common in people over age 85, cognitive and psychological changes, social and environmental changes, and then reviews common discussions which clinicians routinely have with these patients and their families. Some hearing and vision loss are a part of normal aging as is decline in immune function. Cardiovascular disease and osteoporosis and dementia are common chronic conditions at age 85. Osteoarthritis, diabetes, and related mobility disability will increase in prevalence as the population ages and becomes more overweight. These population changes have considerable public health importance. Caregiver support, services in the home, assistive technologies, and promotion of home exercise programs as well as consideration of transportation and housing policies are recommended. For clinicians, judicious prescribing and ordering of tests includes a consideration of life expectancy, lag time to benefit, and patient goals. Furthermore, healthy behaviors starting in early childhood can optimize quality of life among the oldest-old.

Racial/ethnic disparities in disability outcomes among post-acute home care patients

OBJECTIVE

To examine activities of daily living (ADL) disability outcomes among racially/ethnically diverse elders receiving home care (HC) after hospitalization.

METHOD

We conducted a retrospective cohort analysis of single-agency, 2013-2014 Outcome and Assessment Information Set data from older adults who received post-hospitalization HC ( n = 20,674). We measured overall change in ADL disability by summing the difference of standardized admission and discharge scores from nine individual ADL. Associations between race/ethnicity and overall ADL change scores were modeled using general linear regression, adjusting for covariates consistent with the Disablement Model.

RESULTS

Overall, patients experienced improvement in ADL disability from HC admission to discharge. However, Asian, African American, and Hispanic patients experienced significantly less improvement compared with non-Hispanic Whites (all p < .001), even after controlling for covariates.

DISCUSSION

Racial/ethnic disparities exist in ADL disability improvement among HC patients. Research is needed to clarify mechanisms underlying these disparities. Disablement Model factors may be targets for clinical intervention.

The effect of intervening hospitalizations on the benefit of structured physical activity in promoting independent mobility among community-living older persons: secondary analysis of a randomized controlled trial

BACKGROUND

Among older persons, disability is often precipitated by intervening illnesses and injuries leading to hospitalization. In the Lifestyle Interventions and Independence for Elders (LIFE) Study, a structured moderate-intensity physical activity program, compared with a health education program, was shown to significantly reduce the amount of time spent with major mobility disability (MMD) over the course of 3.5 years. We aimed to determine whether the benefit of the physical activity program in promoting independent mobility was diminished in the setting of intervening hospitalizations.

METHODS

We analyzed data from a single-blinded, parallel group randomized trial (ClinicalTrials.gov: NCT01072500). In this trial, 1635 sedentary persons, aged 70-89 years, who had functional limitations but were able to walk 400 m, were randomized from eight US centers between February 2010 and December 2013: 818 to physical activity (800 received intervention) and 817 to health education (805 received intervention). Intervening hospitalizations and MMD, defined as the inability to walk 400 m, were assessed every 6 months for up to 3.5 years.

RESULTS

For both the physical activity and health education groups, intervening hospitalizations were strongly associated with the initial onset of MMD and inversely associated with recovery from MMD, defined as a transition from initial MMD onset to no MMD. The benefit of the physical activity intervention did not differ significantly based on hospital exposure. For onset of MMD, the hazard ratios (HR) were 0.79 (95% confidence interval [CI] 0.58-1.1) and 0.77 (0.62-0.95) in the presence and absence of intervening hospitalizations, respectively (P-interaction, 0.903). For recovery of MMD, the magnitude of effect was modestly greater among participants who were hospitalized (HR 1.5, 95% CI 0.71-3.0) than in those who were not hospitalized (HR 1.2, 95% CI 0.88-1.7), but this difference did not achieve statistical significance (P-interaction, 0.670).

CONCLUSIONS

Intervening hospitalizations had strong deleterious effects on the onset of MMD and recovery from MMD, but did not diminish the beneficial effect of the LIFE physical activity intervention in promoting independent mobility. To achieve sustained benefits over time, structured physical activity programs should be designed to accommodate acute illnesses and injuries leading to hospitalizations given their high frequency in older persons with functional limitations.

The Use of Life-Sustaining Procedures in the Last Month of Life Is Associated With More Depressive Symptoms in Surviving Spouses

CONTEXT

Family caregivers of individuals with serious illness who undergo intensive life-sustaining medical procedures at the end of life may be at risk of negative consequences including depression.

OBJECTIVES

The objective of this study was to determine the association between patients' use of life-sustaining procedures at the end of life and depressive symptoms in their surviving spouses.

METHODS

We used data from the Health and Retirement Study, a longitudinal survey of U.S. residents, linked to Medicare claims data. We included married Medicare beneficiaries aged 65 years and older who died between 2000 and 2011 (n = 1258) and their surviving spouses. The use of life-sustaining procedures (i.e., intubation/mechanical ventilation, tracheostomy, gastrostomy tube insertion, enteral/parenteral nutrition, and cardiopulmonary resuscitation) in the last month of life was measured via claims data. Using propensity score matching, we compared change in depressive symptoms of surviving spouses.

RESULTS

Eighteen percent of decedents underwent one or more life-sustaining procedures in the last month of life. Those whose spouses underwent life-sustaining procedures had a 0.32-point increase in depressive symptoms after death (scale range = 0-8) and a greater likelihood of clinically significant depression (odds ratio = 1.51) compared with a matched sample of spouses of those who did not have procedures (P < 0.05).

CONCLUSION

Surviving spouses of those who undergo intensive life-sustaining procedures at the end of life experience a greater magnitude of increase in depressive symptoms than those whose spouses do not undergo such procedures. Further study of the circumstances and decision making surrounding these procedures is needed to understand their relationship with survivors' negative mental health consequences and how best to provide appropriate support.

Factors associated with the recovery of activities of daily living after hospitalization for acute medical illness: a prospective cohort study

[Purpose] This study investigated the factors associated with the recovery rate of activities of daily living of elderly patients hospitalized for acute medical illness. [Subjects and Methods] A total of 238 elderly patients were enrolled in this study. The main outcome measure was the functional independence measure score which was used as an assessment of activities of daily living. The participants were divided into 2 groups based on their activities of daily living before onset: the independent group and the partially dependent group. The participants of each group were further divided into 2 subgroups based on recovery rates of activities of daily living: the high-recovery group (80%) and the low-recovery group (<80%). The factors associated with the recovery rate were examined using multivariate logistic regression analysis. [Results] The factors associated with the recovery rate were: days of inactivity and cognitive status at the start of rehabilitation for the independent group, and days of inactivity and nutritional status at the start of rehabilitation for the partially dependent group. [Conclusion] The results of this study suggest that the important factors for return to normal activities of daily living are: days of inactivity and cognitive status for the independent group; and days of inactivity and management of nutrition for the partially dependent group.

Quality of Life Trajectories Predict Mortality in Older Men: The Manitoba Follow-Up Study

OBJECTIVE

To describe quality of life trajectories of older men over a 10-year time frame in mental and physical health domains, and to determine if these trajectories predict death over a subsequent 9-year period.

METHOD

A cohort study of Royal Canadian Air Force aircrew veterans. We used Short Form-36 (SF-36) measures of mental and physical functioning collected prospectively at six time points between 1996 to 2006 (734 men with a mean age of 85.5 [ SD 3.0] years in 2006) to determine trajectories. Continued contact with the cohort from 2006 to 2015 determined subsequent mortality.

RESULTS

Men were more likely to maintain high levels of mental functioning than physical functioning. Thirty-seven percent of participants maintained a high level of both mental and physical functioning. Declining function in either mental or physical function was associated with lower survival.

CONCLUSION

Men who maintain physical and mental functioning have a lower mortality rate.

Health-Related Quality of Life at Admission Is Associated with Postdischarge Mortality, Functional Decline, and Institutionalization in Acutely Hospitalized Older Medical Patients

OBJECTIVES

To assess the independent association between health-related quality of life (HRQOL) at admission and mortality, functional decline, and institutionalization 3 and 12 months after admission in acutely hospitalized older adults.

DESIGN

Post hoc analysis of data from prospective cohort study, 2006 to 2009, 12-month follow-up.

SETTING

Eleven medical wards in three hospitals in the Netherlands.

PARTICIPANTS

Medical patients aged 65 and older acutely hospitalized for 48 hours or longer (N = 473).

MEASUREMENTS

OUTCOMES

mortality, functional decline, and institutionalization, 3 and 12 months after admission. Main determinant was HRQOL (utility based on the EuroQol-5D at admission, reflecting the relative desirability of a particular health state and is measured on a scale from 0 (death) to 1 (full health). Some health states are regarded as being worse than death, resulting in negative utilities, with a minimum of -0.330). Participants were split into two groups based on median utility at admission. Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using Cox and logistic regression analyses, adjusted for sociodemographic and health variables.

RESULTS

Median utility was 0.775 (interquartile range 0.399-0.861). Utility greater than 0.775, indicating high HRQOL, was associated with lower risk of mortality (hazard ratio = 0.38, 95% CI = 0.18-0.83) and functional decline (OR = 0.47, 95% CI = 0.28-0.79) at 3 months in the adjusted models. At 12 months, these associations were statistically significant in the crude models but not in the adjusted models. Utility was not associated with risk of institutionalization at 3 or 12 months.

CONCLUSION

Higher HRQOL at admission was associated with lower risk of mortality and functional decline 3 months after admission. In older, acutely hospitalized individuals, the EQ-5D may provide a means of risk stratification and may ultimately guide individuals, their families, and professionals in treatment decisions during hospitalization.

Inpatient Walking Activity to Predict Readmission in Older Adults

OBJECTIVE

To compare the 30-day readmission predictive power of in-hospital walking activity and in-hospital activities of daily living (ADLs) in older acutely ill patients. In addition, we sought to identify preliminary walking thresholds that could support the targeting of interventions aimed at minimizing rehospitalizations.

DESIGN

Prospective, observational clinical cohort study. Step counts during hospitalization were assessed via accelerometry. ADL function was assessed within 48 hours of admission.

SETTING

Acute care hospital.

PARTICIPANTS

One hundred sixty-four ambulatory persons aged 65 years and older admitted to the hospital from the community with an acute medical illness.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Readmission back to the index hospital (yes vs no) within 30 days of discharge.

RESULTS

Twenty-six patients (15.8%) were readmitted within 30 days of discharge. Walking activity during hospitalization was more strongly and significantly associated with 30-day readmission (odds ratio=0.90; 95% confidence interval, 0.82-0.98) than ADL function (odds ratio=0.45; 95% confidence interval, 0.14-1.45) after adjusting for relevant readmission risk factors. The predictive accuracy (area under the curve) was highest for models that included walking activity and changed little with the addition of ADLs. A walking threshold of 275 steps or more per day identified patients at reduced 30-day readmission risk.

CONCLUSIONS

Walking activity was a stronger predictor of readmission than ADLs. Monitoring patient activity during hospitalization may provide clinicians with valuable information on early readmission risk not captured by measures of ADLs. Further study is needed to replicate these findings and monitor walking activity posthospitalization to further advance our understanding of readmission risk.

Barriers and facilitators for implementing a new screening tool in an emergency department: A qualitative study applying the Theoretical Domains Framework

AIM

The aim was to identify the factors that were perceived as most important as facilitators or barriers to the introduction and intended use of a new tool in the emergency department among nurses and a geriatric team.

BACKGROUND

A high incidence of functional decline after hospitalisation for acute medical illness has been shown in the oldest patients and those who are physically frail. In Denmark, more than 35% of older medical patients acutely admitted to the emergency department are readmitted within 90 days after discharge. A new screening tool for use in the emergency department aiming to identify patients at particularly high risk of functional decline and readmission was developed.

DESIGN

Qualitative study based on semistructured interviews with nurses and a geriatric team in the emergency department and semistructured single interviews with their managers.

METHODS

The Theoretical Domains Framework guided data collection and analysis. Content analysis was performed whereby new themes and themes already existing within each domain were described.

RESULTS

Six predominant domains were identified: (1) professional role and identity; (2) beliefs about consequences; (3) goals; (4) knowledge; (5) optimism and (6) environmental context and resources. The content analysis identified three themes, each containing two subthemes. The themes were professional role and identity, beliefs about consequences and preconditions for a successful implementation.

CONCLUSIONS

Two different cultures were identified in the emergency department. These cultures applied to different professional roles and identity, different actions and sense making and identified how barriers and facilitators linked to the new screening tool were perceived.

RELEVANCE FOR CLINICAL PRACTICE

The results show that different cultures exist in the same local context and influence the perception of barriers and facilitators differently. These cultures must be identified and addressed when implementation is planned.

In-Hospital Mobility Variations Across Primary Diagnoses Among Older Adults

OBJECTIVES

To examine the relationship between primary diagnoses and mobility impairment and recovery among hospitalized older adults.

DESIGN

Prospective cohort study.

SETTING

UF Health Shands Hospital, an 852-bed level I trauma center located in Gainesville, Florida.

PARTICIPANTS

A total of 18,551 older adults (≥65 years) with 29,148 hospitalizations between January 2009 and April 2014.

MEASUREMENTS

Incident and discharge mobility impairment and recovery were assessed using the Braden activity subscale score that was recorded by the nursing staff at every shift change: approximately 3 times per day. Primary diagnosis ICD-9 codes were used as predictors and recategorized by using the Agency for Health Care Research and Quality Clinical Classification Software.

RESULTS

Of the 15,498 hospital records in which the patient was initially observed to "walk frequently," 3186 (20.6%) developed incident mobility impairment (chair-fast or bedfast). Primary diagnoses with a surgical or invasive procedure were the most prevalent (77.2%) among the hospital observations with incident mobility impairment; otherwise, primary diagnoses without surgery were much more associated with discharge mobility impairment (59%). The highest incidence of mobility impairment occurred in patients with heart valve disorders and aortic and peripheral/visceral artery aneurysms (6.24 and 6.05 events per 30 person-days, respectively); septicemia showed the highest incidence rate for mobility limitation at discharge (0.94 events per 30 person-days). Mobility impairment was observed in 13,650 (46.8% of total) records at admission and 5930 (43.44%) were observed to recover to a state of walking occasionally or frequently. Osteoarthritis and cancer of gastrointestinal organs/peritoneum had the highest incidence rate for mobility recovery (7.68 and 5.63 events per 30 person-days respectively).

CONCLUSIONS

Approximately 1 of 5 patients who were mobile at admission became significantly impaired during hospitalization. However, approximately half (43.4%) of patients observed to have mobility impairment at admission recovered during hospitalization. Conditions most associated with mobility impairment and recovery are varied, but older patients hospitalized for septicemia and cardiovascular diseases with surgery (heart valve disorders and aortic/peripheral/visceral artery aneurysms) appear to be at most risk for incident mobility impairment that did not recover at discharge.

Understanding and reducing disability in older adults following critical illness

OBJECTIVE

To review how disability can develop in older adults with critical illness and to explore ways to reduce long-term disability following critical illness.

DATA SOURCES

We searched PubMed, CINAHL, Web of Science and Google Scholar for studies reporting disability outcomes (i.e., activities of daily living, instrumental activities of daily living, and mobility activities) and/or cognitive outcomes among patients treated in an ICU who were 65 years or older. We also reviewed the bibliographies of relevant citations to identify additional citations.

STUDY SELECTION

We identified 19 studies evaluating disability outcomes in critically ill patients who were 65 years and older.

DATA EXTRACTION

Descriptive epidemiologic data on disability after critical illness.

DATA SYNTHESIS

Newly acquired disability in activities of daily living, instrumental activities of daily living, and mobility activities was commonplace among older adults who survived a critical illness. Incident dementia and less severe cognitive impairment were also highly prevalent. Factors related to the acute critical illness, ICU practices, such as heavy sedation, physical restraints, and immobility, as well as aging physiology, and coexisting geriatric conditions can combine to result in these poor outcomes.

CONCLUSIONS

Older adults who survive critical illness have physical and cognitive declines resulting in disability at greater rates than hospitalized, noncritically ill and community dwelling older adults. Interventions derived from widely available geriatric care models in use outside of the ICU, which address modifiable risk factors including immobility and delirium, are associated with improved functional and cognitive outcomes and can be used to complement ICU-focused models such as the ABCDEs.

Elderly patients attended in emergency health services in Brazil: a study for victims of falls and traffic accidents

The article aims to describe the profile of elderly victims of falls and traffic accidents from the data of the Surveillance Survey of Violence and Accidents (VIVA). The VIVA Survey was conducted in the emergency health-services of the Unified Health System in the capitals of Brazil in 2011. The sample of elderly by type of accident was subjected to the two-step cluster procedure. Of the 2463 elderly persons in question, 79.8% suffered falls and 20.2% were the victims of traffic accidents. The 1812 elderly who fell were grouped together into 4 clusters: Cluster 1, in which all had disabilities; Cluster 2, all were non-white and falls took place in the home; Cluster 3, younger and active seniors; and Cluster 4, with a higher proportion of seniors 80 years old or above who were white. Among cases of traffic accidents, 446 seniors were grouped into two clusters: Cluster 1 of younger elderly, drivers or passengers; Cluster 2, with higher age seniors, mostly pedestrians. The main victims of falls were women with low schooling and unemployed; traffic accident victims were mostly younger and male. Complications were similar in victims of falls and traffic accidents. Clusters allow adoption of targeted measures of care, prevention and health promotion.

Optimal screening for increased risk for adverse outcomes in hospitalised older adults

Background: screening for frailty might help to prevent adverse outcomes in hospitalised older adults.

Objective: to identify the most predictive and efficient screening tool for frailty.

Design and setting: two consecutive observational prospective cohorts in four hospitals in the Netherlands.

Subjects: patients aged ≥70 years, electively or acutely hospitalised for ≥2 days.

Methods: screening instruments included in the Dutch Safety Management Programme [VeiligheidsManagementSysteem (VMS)] on four geriatric domains (ADL, falls, undernutrition and delirium) were used and the Identification of Seniors At Risk, the 6-item Cognitive Impairment Test and the Mini-Mental State Examination were assessed. Three months later, adverse outcomes including functional decline, high-healthcare demand or death were determined. Correlation and regression tree analyses were performed and predictive capacities were assessed.

Results: follow-up data were available of 883 patients. All screening instruments were similarly predictive for adverse outcome (predictive power 0.58–0.66), but the percentage of positively screened patients (13–72%), sensitivity (24–89%) and specificity (35–91%) highly differed. The strongest predictive model for frailty was scoring positive on ≥3 VMS domains if aged 70–80 years; or being aged ≥80 years and scoring positive on ≥1 VMS domains. This tool classified 34% of the patients as frail with a sensitivity of 68% and a specificity of 74%. Comparable results were found in the validation cohort.

Conclusions: the VMS-tool plus age (VMS⁺) offers an efficient instrument to identify frail hospitalised older adults at risk for adverse outcome. In clinical practice, it is important to weigh costs and benefits of screening given the rather low-predictive power of screening instruments.

Disentangling the disabling process: insights from the precipitating events project

Among older persons, disability in activities of daily living is common and highly morbid. The Precipitating Events Project (PEP Study), an ongoing longitudinal study of 754 initially nondisabled, community-living persons, aged 70 or older, was designed to further elucidate the epidemiology of disability, with the goal of informing the development of effective interventions to maintain and restore independent function. Over the past 16 years, participants have completed comprehensive, home-based assessments at 18-month intervals and have been interviewed monthly to reassess their functional status and ascertain intervening events, other health care utilization, and deaths. Findings from the PEP Study have demonstrated that the disabling process for many older persons is characterized by multiple and possibly interrelated disability episodes, even over relatively short periods of time, and that disability often results when an intervening event is superimposed upon a vulnerable host. Given the frequency of assessments, long duration of follow-up, and recent linkage to Medicare data, the PEP Study will continue to be an outstanding platform for disability research in older persons. In addition, as the number of decedents accrues, the PEP Study will increasingly become a valuable resource for investigating symptoms, function, and health care utilization at the end of life.

Activity of daily living trajectories surrounding acute hospitalization of long-stay nursing home residents

OBJECTIVES

To explore patterns of change in nursing home (NH) residents' activities of daily living (ADLs), particularly surrounding acute hospital stays.

DESIGN

Longitudinal study using Medicare and Minimum Data Set (MDS) assessments.

SETTING

National sample of long-stay NH residents.

PARTICIPANTS

NH residents who were hospitalized for the seven most-common inpatient diagnoses (N = 40,128). Each hospital admission was at least 90 days after any prior hospitalization and had at least two preceding MDS assessments.

MEASUREMENTS

The MDS ADL long-form score, a simple sum of seven self-care variables coded from 0 (independent) to 4 (totally dependent) was used to indicate resident ADL function. Scores ranged from 0 to 28, with higher scores indicating greater impairment. A linear mixed model describing ADL trajectories was jointly estimated with time-to-event models for mortality and hospital readmission.

RESULTS

Before hospitalization, the most common trajectory was stable (53.7%), with 27.5% of residents worsening and 18.8% improving. ADL function after hospital discharge was most often characterized as stable (43.1%) or worsening (39.2%). Mortality (20.3%) was higher for those with worsening prehospital ADL function (28.9%) than for those with stable (19.1%) or improving (11.3%) trajectories. Hospital diagnosis was associated with amount of ADL worsening and rate of subsequent ADL change. Most residents with the best initial function continued to worsen after hospital discharge. Cognitive impairment was associated with poorer ADL function and accelerated worsening of ADLs.

CONCLUSION

For many long-stay NH residents, substantial and sustained ADL worsening accompanies acute hospitalization, so acute hospitalization presents an opportunity to revisit care goals; the results of the current study can help inform decision-making.

Function focused care approaches: literature review of progress and future possibilities

BACKGROUND

Consistent with a care approach that optimizes the underlying ability of the patient/resident, the Omnibus Budget Reconciliation Act of 1987 mandated that residents attain and maintain their highest level of function. Restorative Care, which more recently has been referred to as Function Focused Care 4, is a philosophy of care that focuses on evaluating the older adult's underlying capability with regard to function and physical activity and helping him or her optimize and maintain functional abilities and increase time spent in physical activity. The purpose of this review was to consider the work that has been done in testing function focused care and to provide guidance on the best ways in which to integrate this philosophy within any setting.

METHODS

A systematic review of the available literature studying the impact of function focused care approaches was performed using MEDLINE and CINAHL search engines. The studies included were evaluated based on such things as design, specifically whether or not they were experimental designs (which included randomized trials or quasi experimental studies) or single group studies intended to pilot an intervention or for purposes of feasibility; randomization approaches; sample size/number of residents or patients included; descriptions of the intervention such as if there was a champion utilized (research supported or staff); or if motivation of older adults or caregivers was addressed.

RESULTS

Out of 41 articles identified by CINAHL and 148 via MEDLINE, 20 articles met our inclusion and exclusion criteria. Overall the results provided support for the safety and efficacy of function focused care approaches. Continued research is particularly needed to consider best approaches for dissemination and implementation of function focused care and to test function focused care in acute care settings.

Aggregate health burden and the risk of hospitalization in older persons post hip replacement surgery

BACKGROUND

We sought to understand the association between aggregate health burden-chronic conditions, functionally limiting health problems and mental well-being-and the likelihood of hospitalization among older persons post hip replacement surgery.

METHODS

Eight hundred and twenty-eight Medicare recipients from three U.S. states completed a questionnaire 3 years postsurgery. Using administrative data (Medicare Provider Analysis and Review), participants were prospectively followed for 12 months postquestionnaire to capture hospitalizations. Using logistic regression, demographic, socioeconomic, and behavioral characteristics and medical comorbidities were considered as predictors. Subsequently, musculoskeletal (MSK) functional and geriatric problems were added as predictors, then mental well-being and activity limitations. Path analysis was employed to elucidate interrelationships between these predictors, investigating whether mediated effects through mental well-being and activity limitations were operational.

RESULTS

Mean age was 76 years (range: 67-96); 63% were women; 23% had ≥1 hospitalization(s). When medical comorbidity, MSK limitations, and geriatric problems were considered, each was independently associated with hospitalization (odds ratios: 1.3, 1.1, 1.2, respectively). When mental well-being and activity limitations were added, these variables were predictive of hospitalization (odds ratios: 1.2, 1.1, respectively), while MSK limitations and geriatric problems were no longer predictive. Path analysis results suggested that the influence of medical comorbidity and MSK and geriatric problems were mediated through mental well-being and activity limitations.

CONCLUSIONS

Several health domains predict hospitalization, beyond and including medical comorbidity. Efforts aimed at delaying/minimizing hospitalizations in this population should consider an array of domains for potentially targeted intervention. These findings can serve as a baseline against which future research can assess the impact of changes to the health care system.

A comparison and cross-validation of models to predict basic activity of daily living dependency in older adults

BACKGROUND

A simple method of identifying elders at high risk for activity of daily living (ADL) dependence could facilitate essential research and implementation of cost-effective clinical care programs.

OBJECTIVE

We used a nationally representative sample of 9446 older adults free from ADL dependence in 2006 to develop simple models for predicting ADL dependence at 2008 follow-up and to compare the models to the most predictive published model. Candidate predictor variables were those of published models that could be obtained from interview or medical record data.

METHODS

Variable selection was performed using logistic regression with backward elimination in a two-third random sample (n = 6233) and validated in a one-third random sample (n = 3213). Model fit was determined using the c-statistic and evaluated vis-a-vis our replication of a published model.

RESULTS

At 2-year follow-up, 8.0% and 7.3% of initially independent persons were ADL dependent in the development and validation samples, respectively. The best fitting, simple model consisted of age and number of hospitalizations in past 2 years, plus diagnoses of diabetes, chronic lung disease, congestive heart failure, stroke, and arthritis. This model had a c-statistic of 0.74 in the validation sample. A model of just age and number of hospitalizations achieved a c-statistic of 0.71. These compared with a c-statistic of 0.79 for the published model. Sensitivity analyses demonstrated model robustness.

CONCLUSIONS

Models based on a widely available data achieve very good validity for predicting ADL dependence. Future work will assess the validity of these models using medical record data.

Failure to regain function at 3 months after acute hospital admission predicts institutionalization within 12 months in older patients

OBJECTIVES

To study the effects of functional decline on admission to long-term institutionalized care within 12 months from acute hospital admission.

DESIGN

Pooled analyses of 3 longitudinal cohorts.

SETTING

Tertiary and secondary hospital.

PARTICIPANTS

A total of 1085 community-dwelling patients older than 65 years acutely admitted to an internal medicine or orthopedic ward.

MEASUREMENTS

Demographic data and medical data were collected within 2 days from hospital admission. Functional status (activities of daily living [ADL]) was assessed at baseline (reflecting preadmission status 2 weeks before admission) and 3 months after admission, and function loss (change between preadmission and 3 months) was calculated. Living situation was assessed 3 and 12 months after hospitalization. Cox regression analysis was used to predict institutionalization (living in a long-term assisted care or nursing home facility) within 12 months.

RESULTS

ADL function loss in the 3 months following hospital admission increased the risk of institutionalization also in patients without preadmission impairment (loss of function in 1 item HR = 5.3, 95% CI 2.2-12.6, p < .001; ≥2 items HR = 7.3, 95% CI 3.4-15.7, p < .001) compared with patients without impairment and function loss. The risk progressively increased with higher preadmission impairment. Patients with preadmission ADL impairment in 2 or more items without additional loss of function had an increased risk (HR = 6.4, 95% CI 3.1-13.3, p < .001) for institutionalization. This model was adjusted for age, gender, cognitive impairment, social situation, use of health care services, length of hospital stay, and comorbidity.

CONCLUSION

Loss of function in ADL tasks following hospitalization increased the risk for institutionalization, irrespective of preadmission ADL impairment. Potentially, counteracting loss of function in ADLs after acute hospital admission by more intensive rehabilitation may partly reduce the need for institutionalization.

The efficacy of counseling and progressive resistance home-exercises on adherence, health-related quality of life and function after discharge from a geriatric day-hospital

Loss of function and low exercise adherence is common among older people after hospitalization. The aim of this randomized-controlled trial was to evaluate the effects of a combined counseling- and exercise program on changes in health-related quality of life (HRQL) and physical function in patients attending a day hospital and continuing exercise at home. The exercise program consisted of counseling, balance- and progressive resistance training and support from the physical therapist at Geriatric Day-Hospital (GDH) and home for the Intervention-group. The Control-group received counseling, balance-training and support from the physical therapist. The sample was recruited from a GDH in Norway. 108 participants were randomized into the Intervention group (IT) (n=53) or the Control group (CT) (n=55). After 3 months 77 participants were tested. The intention to treat analysis showed that the program had significant benefits in terms of Health Related Quality of Life, measured by SF-36, on the domains vitality and bodily pain, in favor of the IT-group who performed the combined resistance exercises and balance program. All participants increased their scores on physical function, measured by Berg Balance Scale, Timed Up and Go, 5 times Sit-to-Stand, 6 Min Walk Test and Activities Balance Confidence Scale, no group differences. Both groups were adherent to the home exercise program The results show that it is possible to facilitate older people to increase their HRQL, physical function and level of physical activity through counseling, exercise and support from physical therapists.

The effect of testosterone and a nutritional supplement on hospital admissions in under-nourished, older people

Background

Weight loss and under-nutrition are relatively common in older people, and are associated with poor outcomes including increased rates of hospital admissions and death. In a pilot study of 49 undernourished older, community dwelling people we found that daily treatment for one year with a combination of testosterone tablets and a nutritional supplement produced a significant reduction in hospitalizations. We propose a larger, multicentre study to explore and hopefully confirm this exciting, potentially important finding (NHMRC project grant number 627178).

Methods/Design

One year randomized control trial where subjects are allocated to either oral testosterone undecanoate and high calorie oral nutritional supplement or placebo medication and low calorie oral nutritional supplementation. 200 older community-dwelling, undernourished people [Mini Nutritional Assessment score <24 and either: a) low body weight (body mass index, in kg/m²: <22) or b) recent weight loss (>7.5% over 3 months)]. Hospital admissions, quality-adjusted life years, functional status, nutritional health, muscle strength, body composition and other variables will be assessed.

Discussion

The pilot study showed that combined treatment with an oral testosterone and a supplement drink was well tolerated and safe, and reduced the number of people hospitalised and duration of hospital admissions in undernourished, community dwelling older people. This is an exciting finding, as it identifies a treatment which may be of substantial benefit to many older people in our community. We now propose to conduct a multi-centre study to test these findings in a substantially larger subject group, and to determine the cost effectiveness of this treatment.

The relationship between intervening hospitalizations and transitions between frailty states

BACKGROUND

Frailty among older persons is a dynamic process, characterized by frequent transitions between frailty states over time. We performed a prospective longitudinal study to evaluate the relationship between intervening hospitalizations and these transitions.

METHODS

We studied 754 nondisabled community-living persons, aged 70 years or older. Frailty, assessed every 18 months for 108 months, was defined on the basis of muscle weakness, exhaustion, low physical activity, shrinking, and slow walking speed. Participants were classified as frail if they met three or more of these criteria, prefrail if they met one or two of the criteria, or nonfrail if they met none of the criteria. Hospitalizations were ascertained every month for a median of 108 months.

RESULTS

The exposure rates (95% confidence interval) of hospitalization per 1,000 months, based on frailty status at the start of each 18-month interval, were 19.7 (16.2-24.0) nonfrail, 32.9 (29.8-36.2) prefrail, and 57.2 (52.9-63.1) frail. The likelihood of transitioning from states of greater frailty to lesser frailty (ie, recovering) was consistently lower based on exposure to intervening hospitalizations, with adjusted hazard ratios per each hospitalization ranging from 0.46 (95% confidence interval: 0.21-1.03) for the transition from frail to nonfrail states to 0.52 (95% confidence interval: 0.42-0.65) for the transition from prefrail to nonfrail states. Hospitalization had more modest and less consistent effects on transitions from states of lesser frailty to greater frailty. Nonetheless, transitions from nonfrail to frail states were uncommon in the absence of a hospitalization.

CONCLUSIONS

Recovery from prefrail and frail states is substantially diminished by intervening hospitalizations. These results provide additional evidence highlighting the adverse consequences of hospitalization in older persons.
