Predictors of length of hospital stay among older adults admitted to acute care wards: a multicentre observational study

End-of-life symptoms and polypharmacy in lung and other cancer patients receiving palliative care in Turkey

INTRODUCTION

Patients diagnosed with cancer are often prescribed a wide range of medicines. In this study, it was aimed at examining the end-of-life symptoms and polypharmacy status of patients hospitalized in the palliative care unit with the diagnosis of lung cancer and other cancers.

METHODS

The data for the retrospective-descriptive study were obtained from hospital records and an automation system. The sample of the study included the data of all patients (n = 201) who were hospitalized in the palliative care unit between 2016-2021 in Turkey.

RESULTS

The most common symptoms of end-of-life patients were dyspnea (85.1%) and pain (67.7%). The mean number of medications used by the patients on the day of death was 10.89 ± 3.16, it was 12.50 ± 3.11 on the third day before death, 13.24 ± 3.07 on the 6th day before death, 13.50 ± 3.03 on the 9th day before death. There was a statistically significant difference between the mean number of medications used by the patients according to the presence of dyspnea on the day of death (t = 1.997; p = .047) and pain on the day of death (t = 3.781; p = .001). There was a statistically significant difference between the mean number of medications used by the patients according to the presence of pain on the sixth day before death (t = 2.613; p = .010) and the ninth day before death (t = 2.940; p = .004).

CONCLUSION

The number of medications used by the patients decreased from the 9th day before death to the day of death and their polypharmacy status continued.

Patient Profile and Cost Savings of Long-Term Care in a Spanish Hospital: Retrospective Observational Study

BACKGROUND

Long-term care hospitals have been considered an efficient response to the health care needs of an increasingly aging population. These centers are expected to contribute to better hospital bed management and more personalized care for patients needing continuous care. The evaluation of their outcomes is necessary after a sufficient period to assess their impact. Hospitals for Acute and Chronic Long-Term Extended Stay (HACLES) emerged in Spain in the late 20th century as a response to the aging population and the increase in chronic diseases.

OBJECTIVE

This study aimed to analyze the profile of patients treated in a HACLES, particularly analyzing gender differences, and evaluate the cost savings associated with using these centers.

METHODS

A retrospective study was conducted based on data from patients 65 years old or older admitted to a HACLES between 2022 and 2023. Gender, age, household cohabitation data, diagnosis and comorbidity, daily medication intake, and degree of dependency were obtained to describe the profile of patients who attended the HACLES. Data coded in SIA-Abucasis (version 37.00.03; Consellería Sanitat, Generalitat Valenciana; a digital medical record system used in the Valencian region) were reviewed, and descriptive statistics and comparison tests were used. The direct cost savings of HACLES admissions were calculated by comparing the daily cost of a general hospital bed with that of a HACLES bed.

RESULTS

Data from 123 patients with a mean age of 77 years were analyzed. Most (n=81, 65.9%) had a cohabiting family member as their primary caregiver. Palliative care was the most frequent reason for admission (n=75, 61%). The mortality rate (odds ratio [OR] 61.8, 95% CI 53.2-70.5) was similar between men and women (OR 54.1, 95% CI 47.8-71.5 vs OR 59.7, 95% CI 42.2-66.0; P=.23). The cognitive assessment, using the Pfeiffer scale, improved at discharge (mean 3.2, SD 3.2 vs mean 2.5, SD 3.1; P=.003). The length of stay was significantly larger for patients who returned home compared with patients discharged to other facilities (mean 89.8, SD 58.2 versus mean 33.1, SD 43.1 days; P<.001). The direct cost savings were estimated at US $42,614,846 per 1000 admissions.

CONCLUSIONS

Patients typically treated in HACLES are older, with a high level of cognitive impairment and physical dependency, and a significant proportion are in palliative care, highlighting the importance of adapting care to the individual needs of the admitted patients. The HACLES model contributes to the sustainability of the public health system.

Twice daily allied health rehabilitation is feasible in acutely hospitalised older people: an observational study

Objective To evaluate the feasibility of twice daily rehabilitation in older patients admitted to an acute care of the elderly (ACE) hospital ward. Method This was a prospective single-site, cohort study of twice daily interventions provided by ACE physiotherapists, occupational therapists and/or allied health assistants in an ACE hospital ward. The feasibility of twice daily therapy was evaluated using a range of outcomes including satisfaction, fidelity and limited efficacy. Results A total of 220 patients were included (median age 86 [IQR 81-91]years, 54% female, with a median length of hospital stay of 7 [IQR 5-10] days). Twice daily therapy was delivered on 71% (n =757) of patient admitted weekdays (fidelity). Moderate-to-large effect sizes were observed in patient functional and mobility measures during their hospital stay and most patients (74%) were able to be successfully discharged home (limited efficacy). Both staff and patients reported high levels of satisfaction with physiotherapy and occupational therapy while on the ACE ward. Conclusion Twice daily therapy with acutely hospitalised elderly patients is feasible, facilitated discharge home, and is associated with high patient and staff satisfaction.

Association of Age, Frailty, and Strategy for Initiation of Renal-Replacement Therapy: A Post Hoc analysis of the STARRT-Acute Kidney Injury Trial

INTRODUCTION

This study was designed to assess the association of age and frailty with clinical outcomes in patients with severe acute kidney injury (AKI), according to accelerated and standard renal-replacement therapy (RRT) initiation strategies in the STARRT-AKI trial.

METHODS

This was a secondary analysis of an international randomized trial. Older age was defined as ≥65 years. Frailty was assessed using the clinical frailty scale (CFS) score and defined as a score ≥5. The primary outcome was all-cause mortality at 90 days. Secondary outcomes included RRT dependence and RRT-free days at 90 days. We used logistic and linear regression and interaction testing to explore the impact of age and frailty on clinical outcomes.

RESULTS

Of 2,927 patients randomized in the STARRT-AKI trial, 1,616 (55.2%) were aged ≥65 years (median [interquartile range] 73.9 [69.4-78.9]). Older patients had greater comorbid cardiovascular and chronic kidney disease, were more likely to be surgical admissions and to receive vasopressors at baseline. Older patients had higher 90-day mortality (50.4% vs. 35.6%, adjusted-odds ratio (OR), 1.81 [1.53-2.13], p < 0.001). There was no significant difference in RRT dependence at 90 days between older and younger patients (8.7% vs. 7.8%, adjusted-OR, 1.21 [0.82-1.79], p = 0.325). Patients with frailty had higher mortality; but no difference in RRT dependence at 90 days. There was no significant interaction between age and CFS score in relation to mortality, RRT dependence at 90 days, and other secondary outcomes. There was no significant difference in the proportion of patients who received RRT in the standard-strategy stratified by age groups (adjusted-OR, 0.85 [0.67-1.08], p = 0.180).

CONCLUSION

In this secondary analysis of the STARRT-AKI trial, older and frail patients had higher mortality at 90 days; however, there was no difference in RRT dependence. Mortality and RRT dependence were not modified by RRT initiation strategy in older or frail patients.

Prehospital prediction of hospital admission for emergent acuity patients transported by paramedics: A population-based cohort study using machine learning

INTRODUCTION

The closest emergency department (ED) may not always be the optimal hospital for certain stable high acuity patients if further distanced ED's can provide specialized care or are less overcrowded. Machine learning (ML) predictions may support paramedic decision-making to transport a subgroup of emergent patients to a more suitable, albeit more distanced, ED if hospital admission is unlikely. We examined whether characteristics known to paramedics in the prehospital setting were predictive of hospital admission in emergent acuity patients.

MATERIALS AND METHODS

We conducted a population-level cohort study using four ML algorithms to analyze ED visits of the National Ambulatory Care Reporting System from January 1, 2018 to December 31, 2019 in Ontario, Canada. We included all adult patients (≥18 years) transported to the ED by paramedics with an emergent Canadian Triage Acuity Scale score. We included eight characteristic classes as model predictors that are recorded at ED triage. All ML algorithms were trained and assessed using 10-fold cross-validation to predict hospital admission from the ED. Predictive model performance was determined using the area under curve (AUC) with 95% confidence intervals and probabilistic accuracy using the Brier Scaled score. Variable importance scores were computed to determine the top 10 predictors of hospital admission.

RESULTS

All machine learning algorithms demonstrated acceptable accuracy in predicting hospital admission (AUC 0.77-0.78, Brier Scaled 0.22-0.24). The characteristics most predictive of admission were age between 65 to 105 years, referral source from a residential care facility, presenting with a respiratory complaint, and receiving home care.

DISCUSSION

Hospital admission was accurately predicted based on patient characteristics known prehospital to paramedics prior to arrival. Our results support consideration of policy modification to permit certain emergent acuity patients to be transported to a further distanced ED. Additionally, this study demonstrates the utility of ML in paramedic and prehospital research.

Potentially inappropriate medications with older people in intensive care and associated factors: a historic cohort study

BACKGROUND

The epidemiology of potentially inappropriate medications (PIMs) in critical care units remains limited, especially in terms of the factors associated with their use.

OBJECTIVE

To estimate the incidence and factors associated with PIMs use in intensive care units.

DESIGN AND SETTING

Historical cohort study was conducted in a high-complexity hospital in Brazil.

METHODS

A retrospective chart review was conducted on 314 patients aged ≥ 60 years who were admitted to intensive care units (ICUs) at a high-complexity hospital in Brazil. The dates were extracted from a "Patient Safety Project" database. A Chi-square test, Student's t-test, and multivariable logistic regression analyses were performed to assess which factors were associated with PIMs. The statistical significance was set at 5%.

RESULTS

According to Beers' criteria, 12.8% of the identified drugs were considered inappropriate for the elderly population. The incidence rate of PIMs use was 45.8%. The most frequently used PIMs were metoclopramide, insulin, antipsychotics, non-steroidal anti-inflammatory drugs, and benzodiazepines. Factors associated with PIMs use were the number of medications (odds ratio [OR] = 1.17), length of hospital stay (OR = 1.07), and excessive potential drug interactions (OR = 2.43).

CONCLUSIONS

Approximately half of the older adults in ICUs received PIM. Patients taking PIMs had a longer length of stay in the ICU, higher numbers of medications, and higher numbers of potential drug interactions. In ICUs, the use of explicit methods combined with clinical judgment can contribute to the safety and quality of medication prescriptions.

Hospital length of stay and 30-day readmissions in older people: their association in a 20-year cohort study in Italy

BACKGROUND

There are conflicting data on whether hospital length of stay (LOS) reduction affects readmission rates in older adults. We explored 20-year trends of hospital LOS and 30-day rehospitalizations in a cohort of Italian older people, and investigated their association.

METHODS

Participants in the Pro.V.A. project (n = 3099) were followed-up from 1996 to 2018. LOS and 30-day rehospitalizations, i.e. new hospitalizations within 30 days from a previous discharge, were obtained from personal interviews and regional registers. Rehospitalizations in the 6 months before death were also assessed. Linear regressions evaluated the associations between LOS and the frequency of 30-day rehospitalizations, adjusting for the mean age of the cohort within each year.

RESULTS

Over 20 years, 2320 (74.9%) participants were hospitalized. Mean LOS gradually decreased from 17.3 days in 1996 to 11.3 days in 2018, while 30-day rehospitalization rates increased from 6.6% in 1996 to 13.6% in 2018. LOS was inversely associated with 30-day rehospitalizations frequency over time (β = -2.33, p = 0.01), similarly in men and women. A total of 1506 individuals was hospitalized within 6 months before death. The frequency of 30-day readmissions at the end of life increased from 1.4% in 1997 to 8.3% in 2017 and was associated with mean LOS (β = -1.17, p = 0.03).

CONCLUSIONS

The gradual LOS reduction observed in the latter decades is associated with higher 30-day readmission rates in older patients in Italy. This suggests that a careful pre-discharge assessment is warranted in older people, and that community healthcare services should be improved to reduce the risk of readmission.

Length of hospital stay and associated factors among heart failure patients admitted to the University Hospital in Northwest Ethiopia

BACKGROUND

A prolonged length of hospital stay during heart failure-related hospitalization results in frequent readmission and high mortality. The study was aimed to determine the length of hospital stays and associated factors among heart failure patients.

METHODS

A prospective hospital-based cross-sectional study was carried out to determine the length of hospital stay and associated factors among heart failure patients admitted to the medical ward of the University of Gondar Comprehensive Specialized Hospital from January 2019 to June 2020. Multiple linear regression was used to identify factors associated with length of hospital stay and reported with a 95% Confidence Interval (CI). P-value ≤ 0.05 was considered as statistically significant to declare the association.

RESULT

A total of 263 heart failure patients (mean age: 51.08 ± 19.24 years) were included. The mean length of hospital stay was 17.29 ± 7.27 days. Number of comorbidities (B = 1.494, p < 0.001), admission respiratory rate (B = -0.242, p = 0.009), serum potassium (B = -1.525, p = 0.005), third heart sound (B = -4.118, p = 0.005), paroxysmal nocturnal dyspnea (B = 2.494, p = 0.004), causes of acute heart failure; hypertensive heart disease (B = -6.349, p = 0.005), and precipitating factors of acute heart failure; infection (B = 2.867, p = 0.037) were significantly associated with length of hospital stay. Number of comorbidities, paroxysmal nocturnal dyspnea, and precipitating factors of AHF specifically infection were associated with a prolonged length of hospital stay.

CONCLUSION

Heart failure patients admitted to the medical ward had prolonged hospital stays. Thus, clinicians would be aware of the clinical features contributing to the longer hospital stay and implementation of interventions or strategies that could reduce the heart failure patient's hospital stay is necessary.

Missed nursing care: a snapshot case study in a medical ward in Australia

BACKGROUND

Missed nursing care is a global issue in acute healthcare settings. It is a complex phenomenon that refers to nursing care that is required by patients but left undone or significantly delayed.

AIM

To investigate the nature of missed nursing care and influencing factors in a general medical ward in an acute care hospital in Brisbane, Australia.

METHOD

This is a descriptive case study. The study was carried out in a 29-bed inpatient general medical/cardiology/telemetry ward in an acute care tertiary hospital.

RESULTS

The study ward has been identified as a high complexity unit. The survey data found that the most frequent nursing care elements missed, as reported by the patients, were oral care, response to machine beep, and response to call light. The most frequent nurse-reported missed care items were ambulation, monitoring fluid intake/output and attendance at interdisciplinary conferences.

CONCLUSION

Despite mandating nurse-to-patient ratios in the study ward, inadequate staffing was still perceived as being problematic and one of the most frequent reasons leading to missed nursing care. This possible disconnect between mandated staffing ratios and the persistence of perceived missed care suggests a more complex relationship than can be managed by macro (large-scale) resourcing formulas alone.

Italian Dementia-Friendly Hospital Trial (IDENTITÀ): efficacy of a dementia care intervention for hospital staff

This study investigated the short-term impact and the retention of a dementia care intervention for healthcare staff working in an Italian acute hospital setting. Additionally, we identified the predictors of improvement across the intervention. Sixty-two healthcare staff from an Italian public hospital participated in a dementia care intervention consisting of 5 modules delivered in a 5-hour training program focusing on dementia management, knowledge, and care. A pre-test/post-test and six-months follow-up design was used to evaluate participants' changes in knowledge, attitudes, and confidence in dementia. The intervention significantly improved healthcare staff's dementia knowledge and confidence immediately after the end of the intervention. No significant changes were observed from post-test to follow-up, indicating retention of these outcomes over six months. Regarding attitude to dementia, we found an immediate improvement only in the Recognition of Personhood scale. Looking at the predictors of improvement, healthcare staff with lower levels of knowledge, attitudes, and confidence in dementia at pre-test were those who improved more following the intervention. These findings provide further evidence that dementia care interventions are suitable initiatives to promote knowledge and skills required to manage the needs of people with dementia in an acute hospital setting.

Extended length of stay and related costs associated with dementia in acute care hospitals in Ireland

OBJECTIVE

To estimate the additional impact of dementia on in-patient length of stay (LOS) and related costs in Irish acute hospitals. Both principal and secondary diagnosis effects are estimated and valued.

METHODS

This is a cross-sectional study based on administrative data collected on all public hospital in-patient discharges in Ireland for people aged 65 years and older in 2019. Coarsened exact matching (CEM) was undertaken to account for observed confounders between dementia and non-dementia groups, while generalised linear modelling (GLM) was used to compare differences in LOS.

RESULTS

Patients with a principal diagnosis of dementia spent on average 17.5 (CI: 15.42, 19.56; p < .01) d longer in hospital than similar patients with no principal diagnosis of dementia. LOS was 6.7 (CI: 6.31, 7.14; p < .01) d longer for patients with a secondary diagnosis of dementia compared to similar patients with no secondary diagnosis of dementia. The additional annual cost of care for patients in hospitals with a secondary (principal) diagnosis of dementia was €62.0 million (€13.2 million).

CONCLUSIONS

This study highlights the economic impact of extended LOS for patients with dementia in Irish acute hospitals. Addressing specific dementia-related needs of people in hospital is likely to optimise resource use and decrease health care costs in acute care settings.

In-house testing for COVID-19: effects on length of stay, isolation and the need for inpatient rehabilitation

ObjectiveThe COVID-19 pandemic has strained healthcare worldwide. Its direct complications, management and prognosis have been described. Downstream effects, including length of hospital stay (LOS), implications on discharge planning, and effect of in-house testing require formal study.MethodsA retrospective cohort study of patients suspected of COVID-19 infection admitted at a metropolitan Australian hospital was conducted. Outcomes before and after availability of in-house COVID-19 testing were compared.ResultsA total of 129 admissions were analysed. Indications for COVID-testing were dyspnoea (61.2%), fever (19.3%) and delirium (10.8%). All tested negative for COVID-19. Prior to in-house testing, mean LOS was 7.17 days (s.d. ± 4.2), and mean isolation of 1.8 days (s.d. ± 0.8). After availability of in-house testing, mean LOS was 4.78 days (s.d. ± 4.3) with mean isolation of 1.3 days (s.d. ± 0.9), both statistically significant differences. There were five inpatient falls, equivalent to 14.8 falls per 1000 patient/days. Twenty-two patients (17%) required subsequent sub-acute admission, 15 before in-house testing and five after (P = 0.058); however, a sub-group analysis for age >65 years was performed, and the results were significant (P < 0.05), showing all patients who required subacute admissions were aged >65.ConclusionIn-house COVID-19 testing is suggested to significantly reduce the duration patients spend in isolation and overall LOS in hospital. A shorter period of isolation and hospital LOS may reduce the need for subacute transfer in patients aged greater than 65 years, as well as the rates of inpatient falls. Large scale studies are needed to further elucidate these findings.

Predictors of Functional Improvement, Length of Stay, and Discharge Destination in the Context of an Assess and Restore Program in Hospitalized Older Adults

Assess and restore programs such as Humber’s Elderly Assess and Restore Team (HEART) provide short-term restorative care to prevent functional decline in hospitalized older adults. The aim of this retrospective observational study was to determine which HEART participant characteristics are predictive of functional improvement, decreased length of stay, return to home, and decreased readmission to hospital. Electronic health records were retrospectively examined to gather predictor data. Differences in functional status, excessive length of stay, discharge destination, and hospital readmissions were compared in 547 HEART patients and 547 matched eligible non-participants using ANOVAs, Mann–Whitney, and chi-square tests. The greatest functional improvements (percent Barthel change) were seen in those requiring a one-person assist (M = 39.56) and using a walker (M = 46.07). Difference in excessive length of stay between HEART and non-HEART participants was greatest in those who used a walker (Mdn = 3.80), required a one-person assist (Mdn = 2.00), had a high falls risk (Mdn = 1.80), and had either a lower urinary tract infection (Mdn = 2.25) or pneumonia (Mdn = 1.70). Predictor variables did not affect readmission to the hospital nor return to home. Predictive characteristics should be considered when enrolling patients to assess and restore programs for optimal clinical outcomes.

Hospitalization is associated with handgrip strength decline in older adults: a longitudinal study

BACKGROUND

Hospitalization episodes in older people are considered critical events because they act in a complex interaction among immobilization effects.

AIM

The purpose of this study was to evaluate the effects of hospitalization on older adults' handgrip strength (HGS) and to identify factors related to its performance on the test.

METHODS

A cohort study was conducted in a hospital in Natal, Brazil, and enrolled all patients aged 60 years and older between January 2014, and April 2015. Cognitive (Leganés Cognitive Test) and functional status (Katz Index, Lawton Scale and Functional limitation Nagi), physical performance (HGS and gait speed) and depressive symptom assessment (GDS-15) were evaluated at admission and discharge time, as well as information about health and functional status prior to hospitalization. Linear Mixed Models were used to create a predictive model for handgrip strength.

RESULTS

A total of 1168 hospitalized older adults were evaluated. A significant decrease in HGS means was observed between admission and discharge time for men (28.12 ± 10.35 and 20.22 ± 14.08 Kgf, p < 0.01) and for women (19.18 ± 7.87 and 14.88 ± 9.79 Kgf, p < 0.01). Undergoing surgery and basal values of the Katz Index were associated with worse HGS performance at discharge.

CONCLUSION

A significant decline in handgrip strength during the hospitalization period was observed, which was more pronounced in men. Performing surgery during hospitalization was an important factor for HGS decline in men and women. This study reinforces the importance of early mobilization and muscle strength loss prevention protocols in hospitalized older patients.

Trends and Determinants of Polypharmacy and Potential Drug-Drug Interactions at Discharge From Hospital Between 2009-2015

BACKGROUND

Polypharmacy (PP) and excessive polypharmacy (EPP) are increasingly common and associated with risk of drug-drug interactions (DDIs). We aimed to measure the trends and determinants of PP and DDIs among patients discharged from the Department of Internal Medicine of the Lausanne University Hospital.

METHODS

The retrospective study included 17,742 adult patients discharged between 2009 and 2015. Polypharmacy and EPP were defined as the concomitant prescription of five or more and ten or more drugs, respectively. Drug-drug interactions were defined as any combination of a drug metabolized by a cytochrome P450 or P-glycoprotein, and a drug considered as strong inductor or inhibitor of the corresponding enzyme was defined as a potential interaction.

RESULTS

Three most commonly classes of drugs prescribed were "alimentary tract and metabolism (including insulins)," "nervous system," and "blood and blood forming organs." Polypharmacy decreased from 45% in 2009 to 41% in 2015, whereas EPP increased from 40% to 46%. In 2015, 13% of patients received 15 or more drugs. Age, coming from other health care settings, higher Charlson Index, number of comorbidities, and quartiles of length of stay were significantly and independently associated with PP and EPP. The risk of having at least one DDI decreased from 67.0% (95% confidence interval = 64.8-69.0) in 2009 to 59.3% (57.6-62.0) in 2015 (P < 0.001). Multivariate analysis showed number of drugs (odds ratio and 95% confidence interval = 3.68 [3.3-4.1], 9.39 [8.3-10.6], and 20.5 [17.3-28.4] for [5-9], [10-14], and 15+ drugs, respectively), gastrointestinal disease (3.13 [2.73-3.58]), and cancer (1.37 [1.18-1.58]) to be positively associated, and lung (0.82 [0.74-0.90]) and endocrinological (0.62 [0.52-0.74]) diseases to be negatively associated with risk of DDI.

CONCLUSIONS

The pattern of drug prescription has changed and most prescribed groups increased during the study period. Excessive polypharmacy is increasing among hospital patients. The decrease in the overall risk of DDI could be due to an improved management of multidrug therapy.

STOPP-START Medication Review: A Non-Randomized Trial in an Indonesian Tertiary Hospital to Improve Medication Appropriateness and to Reduce the Length of Stay of Older Adults

Background: Inappropriate prescribing may lead to medication errors among older adults. Pharmacists can curb the occurrences of these errors by conducting medication reviews. Screening Tool of Older Person's Prescriptions (STOPP) or Screening Tool to Alert doctors to Right Treatments (START) may curb the incidence of adverse drug reactions and improve medication appropriateness by providing guides about when particular types of medications should be started or stopped. Objective: This study aimed to evaluate the use of STOPP/START to improve the Adapted Medication Appropriateness Index (MAI), to reduce the risk of ADRs (GerontoNet score), and length of stay (LOS). Setting: Geriatric Inpatient Ward, Sanglah General Hospital, Bali, Indonesia. Method: A non-randomized controlled trial was conducted in older adults (>60 years) who were selected consecutively from inpatient units in a tertiary hospital in Bali, Indonesia. The intervention group received medication reviews by pharmacists in collaboration with physicians to assess its appropriateness with STOPP/START criteria on admission and during their stay at the hospital. The control group obtained standard care. Main Outcome Measures: The outcomes were measured using the Adapted MAI, GerontoNet Score, and LOS. Results: Thirty patients in the intervention group and 33 patients in the control group were included in this study. The adapted MAI was 2.97 (2.25) and 9.94 (6.14) with P < .001. The GerontoNet score was 3.33 (2.28) and 5.18 (2.10) with P = .003, LOS was 7.63 (3.00) days and 14.18 (9.97) days with P = .011, respectively. Conclusion: The use of STOPP/START as a tool for medication review improved medication appropriateness and reduced ADR risk and LOS.

Walking Speed and Mortality: An Updated Systematic Review

OBJECTIVE

The aim of our systematic review was to update the current evidence on the association between slow walking speed (WS) and mortality, expanding the current knowledge available in the literature.

METHODS

A systematic review of the published data on the association of WS and mortality was carried out by searching on PubMed and ISI Web of Knowledge databases.

RESULTS

From a title and abstract analysis, 61 articles were included that met the prespecified criteria. After a full-text analysis, 6 articles were excluded and the remaining articles accounted for 120,838 patients and > 25,148 deaths were registered. The duration of follow-ups ranged between 2 and 21 years. In general, studies have shown a consistent association between WS and mortality from all causes.

CONCLUSIONS

WS showed continuous and consistent evidence to be a good predictor of mortality. As such, our study supports the use of this tool in clinical practice as a way to improve health care.

Cognitive Impairment and Length of Stay in Acute Care Hospitals: A Scoping Review of the Literature

Older persons experiencing a longer length of stay (LOS) or delayed discharge (DD) may see a decline in their health and well-being, generating significant costs. This review aimed to identify evidence on the impact of cognitive impairment (CI) on acute care hospital LOS/DD. A scoping review of studies examining the association between CI and LOS/DD was performed. We searched six databases; two reviewers independently screened references until November 2019. A narrative synthesis was used to answer the research question; 58 studies were included of which 33 found a positive association between CI and LOS or DD, 8 studies had mixed results, 3 found an inverse relationship, and 14 showed an indirect link between CI-related syndromes and LOS/DD. Thus, cognitive impairment seemed to be frequently associated with increased LOS/DD. Future research should consider CI together with other risks for LOS/DD and also focus on explaining the association between the two.

Polypharmacy in older adults: a narrative review of definitions, epidemiology and consequences

BACKGROUND

The number of older adults has been constantly growing around the globe. Consequently, multimorbidity and related polypharmacy have become an increasing problem. In the absence of an accepted agreement on the definition of polypharmacy, data on its prevalence in various studies are not easily comparable. Besides, the evidence on the potential adverse clinical outcomes related to polypharmacy is limited though polypharmacy has been linked to numerous adverse clinical outcomes. This narrative review aims to find and summarize recent publications on definitions, epidemiology and clinical consequences of polypharmacy.

METHODS

The MEDLINE database was used to identify recent publications on the definition, prevalence and clinical consequences of polypharmacy using their respective common terms and their variations. Systematic reviews and original studies published between 2015 and 2020 were included.

RESULTS

One hundred and forty-three definitions of polypharmacy and associated terms were found. Most of them are numerical definitions. Its prevalence ranges from 4% among community-dwelling older people to over 96.5% in hospitalized patients. In addition, numerous adverse clinical outcomes were associated with polypharmacy.

CONCLUSION

The term polypharmacy is imprecise, and its definition is yet subject to an ongoing debate. The clinically oriented definitions of polypharmacy found in this review such as appropriate or necessary polypharmacy are more useful and relevant. Regardless of the definition, polypharmacy is highly prevalent in older adults, particularly in nursing home residents and hospitalized patients. Approaches to increase the appropriateness of polypharmacy can improve clinical outcomes in older adults.

Pre-operative physical performance as a predictor of in-hospital outcomes in older patients undergoing elective cardiac surgery

OBJECTIVE

Risk stratification of cardiac surgery patients is usually based on the Society of Thoracic Surgeons (STS) score, that has limited predictive value in older persons. We aimed assessing whether the Short Physical Performance Battery (SPPB) improves, beyond the STS score, assessment of hospital prognosis in older patients undergoing elective cardiac surgery.

METHODS

All patients aged 75+ years referred for elective cardiac surgery to Careggi University Hospital (Florence, Italy) from April 2013 to March 2017 were evaluated pre-operatively. Participants were classified according to the STS-Predicted Risk Of Mortality (STS-PROM): low (<4%), intermediate (4 to 8%), and high risk (>8%). Primary study outcomes were hospital mortality and STS-defined major morbidity. Length of hospital stay was an additional outcome.

RESULTS

Out of 235 participants (females: 46.5%; mean age: 79.6 years), 144 (61.3%) were at low, 67 (28.5%) at intermediate and 24 (10.2%) at high risk, based on the STS-PROM. SPPB (mean±SEM) was 8.8 ± 0.2, 7.0 ± 0.5, and 6.0 ± 0.8 in participants at low, intermediate, and high risk, respectively (p<0.001). The primary outcome occurred in 62 participants (26.4%). In low-risk participants, the SPPB score predicted the primary endpoint (adjusted OR 0.77, 95% CI 0.66-0.89 per each point increase; p<0.001) controlling for STS-Major Morbidity or Operative Mortality (STS-MM) score. This result was not observed in the intermediate-high risk group.

CONCLUSIONS

SPPB predicts mortality and major morbidity in older patients undergoing elective cardiac surgery, classified as low risk with the STS risk score. The SPPB, applied preoperatively, might improve risk stratification in older patients undergoing elective cardiac surgery.

Physical performance measures and hospital outcomes among Italian older adults: results from the CRIME project

BACKGROUND

Older adults are a complex population, at risk of adverse events during and after hospital stay.

AIM

To investigate the association of walking speed (WS) and grip strength (GS) with adverse outcomes, during and after hospitalization, among older individuals admitted to acute care wards.

METHODS

Multicentre observational study including 1123 adults aged ≥ 65 years admitted to acute wards in Italy. WS and GS were measured at admission and discharge. Outcomes were length-of-stay, in-hospital mortality, 1-year mortality and rehospitalisation. Length-of-stay was defined as a number of days from admission to discharge/death.

RESULTS

Mean age was 81 ± 7 years, 56% were women. Compared to patients with WS ≥ 0.8 m/sec, those unable to perform or with WS < 0.8 m/sec had a higher likelihood of longer length-of-stay (OR 2.57; 95% CI 1.63-4.03 and 2.42; 95% CI 1.55-3.79) and 1-year mortality and rehospitalization (OR 1.47, 95% CI 1.07-2.01; OR 1.57, 95% CI 1.04-2.37); those unable to perform WS had a higher likelihood of in-hospital mortality (OR 9.59; 95% CI 1.23-14.57) and 1-year mortality (OR 2.60; 95% CI 1.37-4.93). Compared to good GS performers, those unable to perform had a higher likelihood of in-hospital mortality (OR 17.43; 95% CI 3.87-28.46), 1-year mortality ( OR 3.14; 95% CI 1.37-4.93) and combination of 1-year mortality and rehospitalisation (OR 1.46; 95% CI 1.01-2.12); poor GS performers had a higher likelihood of 1-year mortality (OR 1.39; 95% CI 1.03-2.35); participants unable to perform GS had a lower likelihood of rehospitalisation (OR 0.59; 95% CI 0.39-0.89).

CONCLUSION

Walking speed (WS) and grip strength (GS) are easy-to-assess predictors of length-of-stay, in-hospital and post-discharge death and should be incorporated in the standard assessment of hospitalized patients.

Length of hospital stay among oldest-old patients in acute geriatric ward

PURPOSE

To examine risk factors for prolonged hospital length of stay (LOS) in the oldest-old inpatients aged ≥ 90.

METHODS

This retrospective cross-sectional study was performed in acute Geriatrics Department at Kaplan Medical Center. The target population was the oldest-old inpatients aged ≥ 90 hospitalized with acute illness. In total 1536 admissions of 987 patients admitted between January 2007 and December 2010 from the emergency room were included in the study. We retrieved from the electronic hospital records the following data: demographics, admission diagnosis, comorbidities, laboratory tests, drugs, functional and cognitive status, Charlson Comorbidity Index (CCI) score and age-adjusted CCI score.

RESULTS

The risk factors for a prolonged LOS were tube-feeding, consumption of ≥ 5 drugs, non-independent functional status, diagnosis of urinary tract infection (UTI), pneumonia and malignancy on admission, and comorbidities of congestive heart failure (CHF) and hypoalbuminemia. Multiple linear regression analysis found that UTI, hypoalbuminemia, elevated troponin, pneumonia, number of drugs, malignancy, CHF and number of comorbidities explain a higher risk for a longer LOS.

CONCLUSION

Hospital LOS in the oldest-old patients in acute geriatric ward was associated with admission diagnosis and comorbidities. Awareness of the risk factors for a longer LOS might contribute to reducing hospitalization stay and its related negative consequences. Accurate prediction of prolonged LOS in this age group of patients may be more challenging and require variables that were not included in our study. Future research is warranted.

Assisted Walking Program on Walking Ability in In-Hospital Geriatric Patients: A Randomized Trial

OBJECTIVES

The main aim of this study was to evaluate if an individualized assisted walking program (IAWP) for hospitalized older patients could improve walking ability compared with usual geriatric care and rehabilitation.

DESIGN

A randomized controlled trial with an active control group, open labeled with parallel assignment was conducted between October 2018 and January 2020.

SETTING

Geriatric ward.

PARTICIPANTS

A total of 387 hospitalized patients (≥65 years) were randomly assigned to an intervention or control (usual-care) group.

INTERVENTION

The control group received usual hospital care. The intervention group received also an IAWP.

MEASUREMENTS

The primary endpoint was change in walking ability from hospital admission (considering both current and pre-admission status) to discharge, as assessed with the Braden Activity subscale measures. The secondary endpoint was the occurrence of in-hospital adverse events, such as complications of mobility, pressure ulcers, falls, pain and mortality, and the length of hospital stay. Intention-to-treat and per-protocol analyses were performed.

RESULTS

Baseline characteristics were similar between intervention and control groups. The intervention group, relative to the control group, had significantly improved walking ability at discharge (P < .001). There were no statistically significant differences between the groups in terms of in-hospital adverse events. No adverse effects were detected.

CONCLUSION

In in-hospital patients aged 65 and older, an IAWP improves walking ability at discharge.

Association of Self-Reported Medication Adherence with Potentially Inappropriate Medications in Elderly Patients: A Cross-Sectional Pilot Study

BACKGROUND

Polypharmacy (PP) and potentially inappropriate medications (PIMs) cause problematic drug-related issues in elderly patients; however, little is known about the association between medication adherence and PP and PIMs. This study evaluated the association of self-reported medication adherence with PP and PIMs in elderly patients.

METHODS

A cross-sectional pilot study was conducted using data collected from electronic medical records of 142 self-administering patients aged ≥65 years, excluding emergency hospitalization cases. Self-reported medication adherence was assessed using the visual analogue scale (VAS).

RESULTS

Of the 142 patients, 91 (64.1%) had PP and 80 (56.3%) used at least one PIM. In univariate analysis, patients with a VAS score of 100% had a significantly higher number of female patients and ≥1 PIM use compared to other patients. We found no association between the VAS score and PP. In multivariable analysis, the use of PIMs was significantly associated with a VAS score of 100% (odds ratio = 2.32; 95% confidence interval = 1.16-4.72; p = 0.017).

CONCLUSIONS

Use of PIMs by elderly patients is significantly associated with self-reported medication adherence. Pharmacists should pay more attention to prescribed medications of self-administering elderly patients in order to improve their prescribing quality.

Ultrasound assessment of deep tissue on the wound bed and periwound skin: A classification system using ultrasound images

AIMS

Given the utility of ultrasonography in assessing pressure injury, some ultrasonographic findings have already been used as indicators of deep tissue pressure injury. Despite reports showing that a cloud-like ultrasonographic pattern reflected the presence of deep tissue necrosis, identifying cloud-like patterns was difficult given the presence of similar findings, such as a cobblestone-like pattern. This case series reports patients with pressure injuries who presented with a cloud-like (five cases) and cobblestone-like (four cases) pattern during ultrasonography.

METHODS

This study was conducted at a Japanese university hospital. Participants included patients who underwent routine examination by an interdisciplinary pressure injury team. Pressure injury severity was assessed using the DESIGN-R® scoring system and the wound size were measured using ImageJ software based on the wound photograph.

RESULTS

Among the five cases showing a cloud-like pattern upon ultrasonography, all exhibited an increase in the total DESIGN-R® score, while three exhibited an increase in wound size. On the other hand, all four cases showing a cobblestone-like pattern displayed no increase in the total DESIGN-R® score and a decrease in wound size.

CONCLUSION

This study suggested that distinguishing between cloud-like and cobblestone-like ultrasonography patterns is necessary for determining the presence or absence of deep tissue pressure injury. In order to comprehensively assess pressure injuries with ultrasonography, future studies should be conducted in a large number of participants.

Predictors of Exceeding Target Inpatient Rehabilitation Length of Stay After Hip Fracture

OBJECTIVE

The aim of the study was to identify factors associated with exceeding a target inpatient rehabilitation length of stay of 28 days or less for individuals with hip fracture.

DESIGN

Retrospective cohort study of hip fracture patients admitted to an urban Canadian inpatient rehabilitation facility between January 1, 2013, and January 1, 2018. Patient characteristics previously shown to be associated with individual outcomes and/or length of stay after hip fracture were extracted from the institution's data warehouse. Regression models were used to examine factors associated with exceeding target length of stay as well as overall length of stay.

RESULTS

Four hundred ninety-three subjects were included in the analysis. Three hundred forty-five (70%) met and 148 (30%) exceeded their target length of stay. Patients who exceeded their target were more likely to be elderly (odds ratio, 1.05; 95% confidence interval, 1.02-1.08), to live alone prefracture (odds ratio, 1.72; 95% confidence interval, 1.02-2.91), to have dementia (odds ratio, 2.79; 95% confidence interval, 1.12-6.97), and higher admission pain scores (severe pain odds ratio, 2.51; 95% confidence interval, 1.06-5.93). Higher admission motor Functional Independence Measure scores (odds ratio, 0.95; 95% confidence interval, 0.92-0.98) were protective.

CONCLUSIONS

Advancing age, having dementia, living alone prefracture, and reporting moderate or severe pain at the time of admission not only increased the odds of an individual exceeding their target length of stay but also was associated with an overall increase in length of stay. Conversely, having a higher admission motor Functional Independence Measure score was protective.

Pressure injury data in Australian acute care settings: A comparison of three data sets

Hospital-acquired pressure injuries (HAPIs) represent a serious clinical and economic problem. The cost of treating HAPIs in Australian public hospitals was recently reported at AUS$983 million per annum. There are three main sources of data for documenting pressure injury (PI) occurrence in Australian hospitals: incident reporting, medical record coded data, and real-time surveys of pressure injury. PI data reported at hospital level and to external agencies using these three different sources are variable. This reporting issue leads to inaccurate data interpretation and hinders improvement in accuracy of PI identification and PI prevention. This study involved a comparison of the three different data sources in selected Australian hospitals, to improve the accuracy and comparability of data. Findings from this study provide benchmark areas for improvement in PI documenting and reporting. Better understanding the agreement between the three data sets could lead to a more efficient and effective sharing of data sources.

Non-contact monitoring of agitation and use of a sheltering device in patients with dementia in emergency departments: a feasibility study

BACKGROUND

Agitation is common in geriatric patients with cognitive impairment, e.g. in persons with dementia (PWD), who are admitted to an emergency department (ED). It might be a first sign of upcoming delirium and is associated with a higher risk of an unfavorable clinical course. Hence, monitoring of vital signs and enhanced movement as indicators of upcoming agitation is essential in these patients during their stay in the ED. Since PWD rarely tolerate fixed monitoring devices, a novel developed non-contact monitoring system (NCMSys) might represent an appropriate alternative. Aim of this feasibility study was to test the validity of a NCMSys and of the tent-like "Charité Dome" (ChD), aimed to shelter PWD from the busy ED environment. Furthermore, effects of the ChD on wellbeing and agitation of PWD were investigated.

METHODS

Both devices were attached to patient's bed. Tests on technical validity and safety issues of NCMSys and ChD were performed at the iDoc institute with six healthy volunteers. A feasibility study evaluating the reliability of the NCMSys with and without the ChD was performed in the real-life setting of an ED and on a geriatric-gerontopsychiatric ward. 19 patients were included, ten males and nine females; mean age: 77.4 (55-93) years of which 14 were PWD. PWD inclusion criteria were age ≥ 55 years, a dementia diagnosis and a written consent (by patients or by a custodian). Exclusion criteria were acute life-threatening situations and a missing consent.

RESULTS

Measurements of heart rate, changes in movement and sound emissions by the NCMSys were valid, whereas patient movements affected respiratory rate measurements. The ChD did not impact patients' vital signs or movements in our study setting. However, 53% of the PWD (7/13) and most of the patients without dementia (4/5) benefited from its use regarding their agitation and overall wellbeing.

CONCLUSIONS

The results of this feasibility study encourage a future controlled clinical trial in geriatric ED patients, including PWD, to further evaluate if our concept of non-contact measurement of vital signs and movement combined with the "Charité Dome" helps to prevent upcoming agitation in this vulnerable patient group in the ED.

Prevalence of pressure ulcers in hospitalised patients: a cross-sectional study

OBJECTIVE

The main aim of this study was to estimate the prevalence of pressure ulcers (PU) and related risk factors of PU development in hospitalised patients in Italy. Furthermore, the study investigated the association between risk factors for PU present on admission and the development during hospitalisation (hospital-acquired pressure ulcer, HAPU).

METHODS

A cross-sectional study, using two separate designs at two separate timepoints: 2010 and 2015. The methodology used to measure PU prevalence was that recommended by the European Pressure Ulcer Advisory Panel (EPUAP).

RESULTS

The total sample was 7681 hospitalised patients (3011 patients in 2010, 4670 in 2015). Prevalence of PU in hospital was 19.5% in 2010 and 17% in 2015. The number of patients with PU present on admission were 9.60% in 2010 and 9.42% in 2015. Patients with HAPU were 5.08% in 2010 and 5.87% in 2015. Older age and comorbidities, and a total Braden score of ≤16 were positively associated with PU present on admission and HAPU in hospitals (p<0.05). A longer length of stay appeared to correlate positively with a better clinical outcome for PU if there were already present on admission. Heterogeneous results emerged for length of stay of >30 days and being admitted to intensive care unit (ICU).

CONCLUSION

Our results are comparable with other European and Italian studies. Most of the risk factors associated with PU development have been confirmed. However, further studies are needed to examine the effects of context on PU present on arrival and HAPU, especially regarding hospital length of stay.

Clinical and functional patient characteristics predict medical needs in older patients at risk of functional decline

Background

The rising number of older multimorbid in-patients has implications for medical care. There is a growing need for the identification of factors predicting the needs of older patients in hospital environments. Our aim was to evaluate the use of clinical and functional patient characteristics for the prediction of medical needs in older hospitalized patients.

Methods

Two hundred forty-two in-patients (57.4% male) aged 78.4 ± 6.4 years, who were consecutively admitted to internal medicine departments of the University Hospital Essen between July 2015 and February 2017, were prospectively enrolled. Patients were assessed upon admission using the Identification of Seniors at Risk (ISAR) screening followed by comprehensive geriatric assessment (CGA). The CGA included standardized instruments for the assessment of activities of daily living (ADL), cognition, mobility, and signs of depression upon admission. In multivariable regressions we evaluated the association of clinical patient characteristics, the ISAR score and CGA results with length of hospital stay, number of nursing hours and receiving physiotherapy as indicators for medical needs. We identified clinical characteristics and risk factors associated with higher medical needs.

Results

The 242 patients spent [median(Q1;Q3)]:9.0(4.0;16.0) days in the hospital, needed 2.0(1.5;2.7) hours of nursing each day, and 34.3% received physiotherapy.

In multivariable regression analyses including clinical patient characteristics, ISAR and CGA domains, the factors age (β = − 0.19, 95% confidence interval (CI) = − 0.66;-0.13), number of admission diagnoses (β = 0.28, 95% CI = 0.16;0.41), ADL impairment (B = 6.66, 95% CI = 3.312;10.01), and signs of depression (B = 6.69, 95% CI = 1.43;11.94) independently predicted length of hospital stay. ADL impairment (B = 1.14, 95%CI = 0.67;1.61), cognition impairment (B = 0.57, 95% CI = 0.07;1.07) and ISAR score (β =0.26, 95% CI = 0.01;0.28) independently predicted nursing hours. The number of admission diagnoses (risk ratio (RR) = 1.06, 95% CI = 1.04;1.08), ADL impairment (RR = 3.54, 95% CI = 2.29;5.47), cognition impairment (RR = 1.77, 95% CI = 1.20;2.62) and signs of depression (RR = 1.99, 95% CI = 1.39;2.85) predicted receiving physiotherapy.

Conclusion

Among older in-patients at risk for functional decline, the number of comorbidities, reduced ADL, cognition impairment and signs of depression are important predictors of length of hospital stay, nursing hours, and receiving physiotherapy during hospital stay.

Factors Associated with Bed-Blocking at a University Hospital (Cantabria, Spain) between 2007 and 2015: A Retrospective Observational Study

Current studies on bed-blocking or delayed discharge for non-medical reasons report important variations depending on the country or setting under study. Research on this subject is clearly important as the current system reveals major inefficiencies. Although there is some agreement on the patient-related factors that contribute to the phenomenon, such as older age or a lack of functional ability, there is greater variability regarding environmental or organizational factors. This study sought to quantify the number of cases and days inappropriately spent in hospital and identify patient characteristics and healthcare service use associated with the total length of stay. All cases of delayed discharge were studied at the hospitalization units of a general university hospital in Northern Spain between 2007 and 2015. According to regression estimates, the following characteristics were related to a longer stay: higher complexity through (Diagnosis-Related Group) DRG weight, a diagnosis that implied a lack of functional ability, surgical treatment, having to wait for a destination upon final discharge or return home. After an initial increase, a reduction in delayed discharge was observed, which was maintained for the duration of the study period. Multi-component interventions related with discharge planning can favor a reduced inefficiency with fewer unnecessary stays.

Length of hospital stay and dementia: A systematic review of observational studies

OBJECTIVE

Hospitalizations of people with dementia (PWD) are often accompanied by complications or functional loss and can lead to adverse outcomes. Unsystematic findings suggest an influence of comorbidities on the extent of differences in the length of hospital stay (LOS). This systematic review aimed to identify and evaluate all studies reporting LOS in PWD as compared to PwoD in general hospitals.

METHODS

A systematic review of observational studies using PubMed and ISI Web of Knowledge. Inclusion criteria comprised original studies written in English or German, assessment of diagnosis of dementia, measurement of LOS, and comparison of people with and without dementia.

RESULTS

Fifty-two of 60 studies reported a longer hospitalization time for PWD compared to PwoD. The extent of the difference in LOS varied between and within countries as well as by type of primary morbidity (eg, injuries, cardiovascular diseases). The range of the LOS difference for studies without restriction to a primary morbidity was -2 to +22 days after matching or adjustment for a variable number and selection of potentially relevant covariates. For studies with injuries/fractures/medical procedures and infectious/vascular disease as the primary morbidity, the range was -2.9 to +12.4 and -11.2 to +21.8 days, respectively.

CONCLUSIONS

The majority of studies reported a longer hospitalization of PWD compared to PwoD. Length of hospital stay seems to be influenced by a variety of medical, social, organizational factors, including reasons for hospital admission, whose role should be explored in detail in further research.

Usefulness of the Braden Scale in Intensive Care Units: A Study Based on Electronic Health Record Data

Nurses working in intensive care units have expressed concern that some categories of the Braden scale such as activity and nutrition are not suitable for intensive care unit patients. Upon examining the validity of the Braden scale using the electronic health data, we found relatively low predictability of the tool. Risk factors from the sensory perception and activity categories were not associated with risk of pressure ulcers.

The Six-Item Cognitive Impairment Test Is Associated with Adverse Outcomes in Acutely Hospitalized Older Patients: A Prospective Cohort Study

Aim

The study aim was to investigate whether cognitive impairment, measured by the Six-Item Cognitive Impairment Test (6-CIT), is an independent predictor of adverse outcomes in acutely hospitalized older patients.

Methods

This was a prospective multicenter study including acutely hospitalized patients aged 70 years and older. Multivariable logistic regression was used to investigate whether impaired cognition (6-CIT ≥11 points) was an independent predictor of 90-day adverse outcome, a composite measure of functional decline and mortality. Secondary endpoints were hospital length of stay, new institutionalization, and in-hospital mortality.

Results

In total, 196 (15.6%) of 1,252 included patients had a 6-CIT ≥11. Median age was 80 years (interquartile range 74–85). Patients with impaired cognition had higher rates of 90-day adverse outcome (41.7% compared to 30.3% in 1,056 not cognitively impaired patients, p = 0.009). Impaired cognition was a predictor of 90-day adverse outcome with a crude odds ratio (OR) of 1.64 (95% CI 1.13–2.39), but statistical significance was lost when fully corrected for possible confounders (OR 1.44, 95% CI 0.98–2.11). For all secondary outcomes, impaired cognition was an independent predictor.

Conclusions

In the acute hospital setting, the 6-CIT is associated with 90-day adverse outcome and is an independent predictor of hospital length of stay, new institutionalization, and in-hospital mortality.

Epidemiology of long-stay patients in a university teaching hospital

BACKGROUND

Patients admitted to acute care hospitals may have multiple comorbidities, and a small proportion may stay for a protracted period.

AIMS

To assess the proportion of hospital patients who are long stay (≥14 days) and evaluate associations with baseline variables and subsequent inpatient morbidity and mortality.

METHODS

This is a retrospective observational study of patients aged ≥18 years staying in hospital for at least 24 h between 1 July 2013 and 30 June 2014.

RESULTS

There were 22 094 admissions in 15 623 patients. The median (interquartile range (IQR)) length of stay (LOS) was 4 (2-8) days, and 10% had a LOS >16 days. Long-stay admissions comprised 13.1% of admissions but used 49.1% of bed days. Long-stay admissions were more likely to be associated with intensive care unit admission (21.2 vs 6.0%), medical emergency team review (20.5 vs 4.3%) and a longer duration of mechanical ventilation (P < 0.0001 all comparisons). Long-stay patients were more likely to develop in-hospital complications, were more likely to die in hospital (8.2 vs 3.1%) and were less likely to be discharged home (P < 0.001 all comparisons). Multiple variable analysis revealed several associations with prolonged stay, including multiple admissions in the study period, the nature of the admitting unit, the Charlson comorbidity index at admission, admission from another hospital and any history of smoking.

CONCLUSIONS

Patients staying at least 14 days comprised one seventh of hospital admissions but used half of bed days and suffered increased in-hospital morbidity and mortality. Several pre-admission associations with prolonged stay were identified.

Pressure injury identification, measurement, coding, and reporting: Key challenges and opportunities

Pressure injury (PI) rates are a commonly used indicator of performance of health care facilities, both in acute and subacute settings. However, measuring PI rates in an accurate and reproducible fashion has been challenging. The consequences of poor measurement may include failure to identify poorly performing institutions or incorrect accusations of poor quality care. In this article, we describe the main challenges in identification, coding, and reporting of PIs. Issues include inconsistent identification of PIs at the time of admission, variations in the intensity of PI detection, and differing approaches to coding and the adjustment for differing risks amongst different patient population. These are compounded by differences in the epidemiological approach because rates will differ according to whether patients are surveyed cross-sectionally (eg, on a set day per month) or if the survey is undertaken at discharge. In some cases, financial incentives may also influence PI reporting. We also discuss potential strategies for improving data collection and benchmarking as an aid to reducing PI prevalence.

A prediction model to identify hospitalised, older adults with reduced physical performance

BACKGROUND

Identifying older adults with reduced physical performance at the time of hospital admission can significantly affect patient management and trajectory. For example, such patients could receive targeted hospital interventions such as routine mobilisation. Furthermore, at the time of discharge, health systems could offer these patients additional therapy to maintain or improve health and prevent institutionalisation or readmission. The principle aim of this study was to identify predictors for persisting, reduced physical performance in older adults following acute hospitalisation.

METHODS

This was a prospective cohort study that enrolled 117 medical patients, ages 65 or older, who were admitted to a short-stay unit in a Danish emergency department. Patients were included in the study if at the time of admission they performed ≤8 repetitions in the 30-s Chair-Stand Test (30s-CST). The primary outcome measure was the number of 30s-CST repetitions (≤ 8 or >8) performed at the time of follow-up, 34 days after admission. Potential predictors within the first 48 h of admission included: age, gender, ability to climb stairs and walk 400 m, difficulties with activities of daily living before admission, falls, physical activity level, self-rated health, use of a walking aid before admission, number of prescribed medications, 30s-CST, and the De Morton Mobility Index.

RESULTS

A total of 78 (67%) patients improved in physical performance in the interval between admission and follow-up assessment, but 76 patients (65%) had persistent reduced physical performance when compared to their baseline (30s-CST ≤ 8). The number of potential predictors was reduced in order to create a simplified prediction model based on 4 variables, namely the use of a walking aid before hospitalisation (score = 1.5), a 30s-CST ≤ 5 (1.8), age > 85 (0.1), and female gender (0.6). A score > 1.8 identified 78% of the older adults who continued to have reduced physical performance following acute hospitalisation.

CONCLUSION

At the time of admission, the variables of age, gender, walking aid use, and a 30s-CST score ≤ 5 enabled clinicians to identify 78% of older adults who had persisting reduced physical performance following acute hospitalisation.

Identification of hospitalized elderly patients at risk for adverse in-hospital outcomes in a university orthopedics and trauma surgery environment

BACKGROUND

As a consequence of demographic changes, hospitals are confronted with increasing numbers of elderly patients, who are at high risk of adverse events during hospitalization. Geriatric risk screening followed by comprehensive geriatric assessment (CGA) and treatment has been requested by geriatric societies and task forces to identify patients at risk. Since empirical evidence on factors predisposing to adverse hospital events is scarce, we now prospectively evaluated implications of geriatric risk screening followed by CGA in a university hospital department of orthopedics and trauma surgery.

METHODS

Three hundred and eighty-one patients ≥75 years admitted to the Department of Orthopedics and Trauma Surgery of the University Hospital Essen received Identification of Seniors at Risk (ISAR) Screening followed by CGA via a geriatric liaison service in case of positive screening results. Associations between ISAR, CGA, comorbid risk factors and diseases, length of hospital stay, number of nursing and physiotherapy hours, and falls during hospital stay were analyzed.

RESULTS

Of 381 ISAR screenings, 327 (85.8%) were positive, confirming a high percentage of patients at risk of adverse events. Of these, 300 CGAs revealed 82.7% abnormal results, indicating activities of daily living impairment combined with cognitive, emotional or mobility disturbances. Abnormal CGA resulted in a longer hospital stay (14.0±10.3 days in ISAR+/CGA abnormal compared with 7.6±7.0 days in ISAR+/CGA normal and 8.1±5.4 days in ISAR-, both p<0.001), increased nursing hours (3.4±1.1 hours/day in ISAR+/CGA abnormal compared with 2.5±1.0 hours/day in ISAR+/CGA normal and 2.2±0.8 hours/day in ISAR-, both p<0.001), and increased falls (7.3% in ISAR+/CGA abnormal, 0% in ISAR+/CGA normal, 1.9% in ISAR-). Physiotherapy hours were only significantly increased in ISAR+/CGA abnormal (3.0±2.7 hours) compared with in ISAR+/CGA normal (1.6±1.4 hours, p<0.001) whereas the comparison with ISAR- (2.4±2.4 hours) did not reach significance (p = 0.368). In multivariable regressions, the CGA domains activities of daily living impairment (assessed by Barthel-Index) and signs of depression (assessed by geriatric depression scale) predicted longer length of hospital stay. High ISAR score, and impairment in activities of daily living and cognition (assessed by mini-mental state examination and clock-drawing test) predicted increased nursing hours, and impairment in activities of daily living and mobility predicted increased physiotherapy hours.

CONCLUSIONS

An abnormal geriatric screening and assessment is associated with longer hospital stay, more nursing and physiotherapy hours, and more falls.

What is polypharmacy? A systematic review of definitions

BACKGROUND

Multimorbidity and the associated use of multiple medicines (polypharmacy), is common in the older population. Despite this, there is no consensus definition for polypharmacy. A systematic review was conducted to identify and summarise polypharmacy definitions in existing literature.

METHODS

The reporting of this systematic review conforms to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) checklist. MEDLINE (Ovid), EMBASE and Cochrane were systematically searched, as well as grey literature, to identify articles which defined the term polypharmacy (without any limits on the types of definitions) and were in English, published between 1st January 2000 and 30th May 2016. Definitions were categorised as i. numerical only (using the number of medications to define polypharmacy), ii. numerical with an associated duration of therapy or healthcare setting (such as during hospital stay) or iii. Descriptive (using a brief description to define polypharmacy).

RESULTS

A total of 1156 articles were identified and 110 articles met the inclusion criteria. Articles not only defined polypharmacy but associated terms such as minor and major polypharmacy. As a result, a total of 138 definitions of polypharmacy and associated terms were obtained. There were 111 numerical only definitions (80.4% of all definitions), 15 numerical definitions which incorporated a duration of therapy or healthcare setting (10.9%) and 12 descriptive definitions (8.7%). The most commonly reported definition of polypharmacy was the numerical definition of five or more medications daily (n = 51, 46.4% of articles), with definitions ranging from two or more to 11 or more medicines. Only 6.4% of articles classified the distinction between appropriate and inappropriate polypharmacy, using descriptive definitions to make this distinction.

CONCLUSIONS

Polypharmacy definitions were variable. Numerical definitions of polypharmacy did not account for specific comorbidities present and make it difficult to assess safety and appropriateness of therapy in the clinical setting.

Notch signaling in cerebrovascular diseases (Review)

The Notch signaling pathway is a crucial regulator of numerous fundamental cellular processes. Increasing evidence suggests that Notch signaling is involved in inflammation and oxidative stress, and thus in the progress of cerebrovascular diseases. In addition, Notch signaling in cerebrovascular diseases is associated with apoptosis, angiogenesis and the function of blood-brain barrier. Despite the contradictory results obtained to date as to whether Notch signaling is harmful or beneficial, the regulation of Notch signaling may provide a novel strategy for the treatment of cerebrovascular diseases.

Cognitive Impairment in Hospitalized Seniors

Cognitive disorders are highly prevalent in hospitalized seniors, and can be due to delirium, dementia, as well as other disorders. Hospitalization can have adverse cognitive effects, and cognitive dysfunction adversely affects hospital outcomes. In this article, the literature is reviewed on how hospitalization affects cognitive function and how cognitive impairment affects hospital outcomes. Possible interventions in cognitively impaired hospitalized seniors are reviewed.

Chronic diseases and geriatric syndromes: The different weight of comorbidity

BACKGROUND

Comorbidity is a relevant health determinant in older adults. Co-occurrence of several diseases and other age-associated conditions generates new clinical phenotypes (geriatric syndromes [GS] as falls, delirium etc.). We investigated the association of chronic diseases, alone or in combination, and GS in older adults receiving home care services in 11 European countries and one Canadian province.

METHODS

Participants were cross-sectionally evaluated with the multidimensional assessment instrument RAI HC. We assessed 14 different diagnoses and 8 GS (pain, urinary incontinence, falls, disability, dizziness, weight loss, pressure ulcers and delirium). Adjusted mean number of GS per participant was calculated for groups of participants with each disease when occurring alone or with comorbidity.

RESULTS

The mean age of the 6903 participants was 82.2±7.4 years and 4750 (69%) were women. Participants presented with an average of 2.6 diseases and 2.0 GS: pain (48%), urinary incontinence (47%) and falls (33%) were the most prevalent. Parkinson's disease, cerebrovascular disease and peripheral artery disease were associated with the highest number of GS (2.5, 2.3 and 2.2, respectively). Conversely, hypertension, diabetes, dementia, cancer and thyroid dysfunction were associated with the lowest number of GS (2.0 on average). For 9/14 examined diseases (hypertension, diabetes, dementia, COPD, heart failure, ischemic heart disease, atrial fibrillation, cancer and thyroid dysfunction) the number of GS increased with the degree of comorbidity.

CONCLUSIONS

Comorbidity and GS are prevalent in older adults receiving home care. Different diseases have a variable impact on occurrence of GS. Comorbidity is not always associated with an increased number of GS.

Patient and organizational characteristics predict a long length of stay in the emergency department - a Swedish cohort study

BACKGROUND

Emergency departments (EDs) constitute a central part of the healthcare system that receives patients with complaints of varied urgency. A long length of stay (LOS) in the ED is associated with crowding, low patient satisfaction and poor patient outcomes. Therefore, it is important to understand the key drivers and patient characteristics associated with long LOS.

AIMS

To identify patient-related and organization-related characteristics associated with the longest ED LOS.

METHODS

All adult visits (n=19 503) to the ED at Karolinska University Hospital in Solna, Sweden, between 8 a.m. and 9 p.m. during 2012 were divided into quartiles on the basis of their LOS. The quartile with the longest LOS (n=4876) was compared with the two intermediate quartiles (n=9752) and the shortest quartile (n=4875). Differences in patient and organizational characteristics were assessed using multivariate logistic regression models to achieve odds ratios (ORs) with 95% confidence intervals (CIs).

RESULTS

The patient-related factors associated with long LOS were female sex (OR 1.22, 95% CI 1.14-1.30), age 65-79 (OR 1.82, 95% CI 1.67-1.97), age 80 or older (OR 2.76, 95% CI 2.52-3.02) and the chief complaint of dyspnoea (OR 1.55, 95% CI 1.39-1.73).

CONCLUSION

Long LOS in the ED is associated with both patient and organizational characteristics and the elderly are at particular risk of long LOS. These insights may be used to improve patient outcome metrics and enhance ED efficiency. Further studies are needed to clarify the role of additional factors as well as the causality of the studied factors.
