Early Markers of Prolonged Hospital Stays in Older People: A Prospective, Multicenter Study of 908 Inpatients in French Acute Hospitals

Impact of geographical cohorting, multidisciplinary rounding and incremental case management support on hospital length of stay and readmission rates: a propensity weighted analysis

Hospital length of stay (LOS) in the USA has been increasing since the start of the COVID-19 pandemic, with numerous negative outcomes, including decreased quality of care, worsened patient satisfaction and negative financial impacts on hospitals. While many proposed factors contributing to prolonged LOS are challenging to modify, poor coordination of care and communication among clinical teams can be improved.Geographical cohorting of provider teams, patients and other clinical staff is proposed as a solution to prolonged LOS and readmissions. However, many studies on geographical cohorting alone have shown no significant impact on LOS or readmissions. Other potential benefits of geographical cohorting include improved quality of care, learning experience, communication, teamwork and efficiency.This paper presents a retrospective study at Duke University Hospital (DUH) on the General Medicine service, deploying a bundled intervention of geographical cohorting of patients and their care teams, twice daily multidisciplinary rounds and incremental case management support. The quality improvement study found that patients in the intervention arm had 16%-17% shorter LOS than those in the control arms, and there was a reduction in 30-day hospital readmissions compared with the concurrent control arm. Moreover, there was some evidence of improved accuracy of estimated discharge dates in the intervention arm.Based on these findings, the health system at DUH recognised the value of geographical cohorting and implemented additional geographically based medicine units with multidisciplinary rounds. Future studies will confirm the sustained impact of these care transformations on hospital throughput and patient outcomes, aiming to reduce LOS and enhance the quality of care provided to patients.

Prognostic value of cognitive impairment, assessed by the Clock Drawing Test, in emergency department patients presenting with non-specific complaints

BACKGROUND

Cognitive impairment (CI) is common among older patients presenting to the emergency department (ED). The failure to recognize CI at ED presentation constitutes a high risk of additional morbidity, mortality, and functional decline. The Clock Drawing Test (CDT) is a well-established cognitive screening test.

AIM

In patients presenting to the ED with non-specific complaints (NSCs), we aimed to investigate the usability of the CDT and its prognostic value regarding length of hospital stay (LOS) and mortality.

METHOD

Secondary analysis of the Basel Non-specific Complaints (BANC) trial, a prospective delayed type cross-sectional study with a 30-day follow-up. In three EDs, patients presenting with NSCs were enrolled. The CDT was administered at enrollment.

RESULTS

In the 1,278 patients enrolled, median age was 81 [74, 87] years and 782 were female (61.19%). A valid CDT was obtained in 737 (57.7%) patients. In patients without a valid CDT median LOS was higher (29 [9, 49] days vs. 22 [9, 45] days), and 30-day mortality was significantly higher than in patients with a valid CDT (n = 45 (8.32%) vs. n = 39 (5.29%)). Of all valid CDTs, 154 clocks (20.9%) were classified as normal, 55 (7.5%) as mildly deficient, 297 (40.3%) as moderately deficient, and 231 (31.3%) as severely deficient. Mortality and LOS increased along with the CDT deficits (p = 0.012 for 30-day mortality; p < 0.001 for LOS).

CONCLUSION

The early identification of patients with CI may lead to improved patient management and resource allocation. The CDT could be used as a risk stratification tool for older ED patients presenting with NSCs, as it is a predictor for 30-day mortality and LOS.

Comparison of National Surgical Quality Improvement Program Surgical Risk Calculator, Trauma and Injury Severity Score, and American Society of Anesthesiologists Physical Status to predict operative trauma mortality in elderly patients

BACKGROUND

The Trauma and Injury Severity Score (TRISS) uses anatomical and physiologic variables to predict mortality. Elderly (65 years or older) trauma patients have increased mortality and morbidity for a given TRISS, in part because of functional status and comorbidities. These factors are incorporated into the American Society of Anesthesiologists Physical Status (ASA-PS) and National Surgical Quality Improvement Program Surgical Risk Calculator (NSQIP-SRC). We hypothesized scoring tools using comorbidities and functional status to be superior at predicting mortality, hospital length of stay (LOS), and complications in elderly trauma patients undergoing operation.

METHODS

Four level I trauma centers prospectively collected data on elderly trauma patients undergoing surgery within 24 hours of admission. Using logistic regression, five scoring models were compared: ASA-PS, NSQIP-SRC, TRISS, TRISS-ASA-PS, and TRISS-NSQIP-SRC.Brier scores and area under the receiver operator characteristics curve were calculated to compare mortality prediction. Adjusted R2 and root mean squared error were used to compare LOS and predictive ability for number of complications.

RESULTS

From 122 subjects, 9 (7.4%) died, and the average LOS was 12.9 days (range, 1-110 days). National Surgical Quality Improvement Program Surgical Risk Calculator was superior to ASA-PS and TRISS at predicting mortality (area under the receiver operator characteristics curve, 0.978 vs. 0.768 vs. 0.903; p = 0.007). Furthermore, NSQIP-SRC was more accurate predicting LOS (R2, 25.9% vs. 13.3% vs. 20.5%) and complications (R2, 34.0% vs. 22.6% vs. 29.4%) compared with TRISS and ASA-PS. Adding TRISS to NSQIP-SRC improved predictive ability compared with NSQIP-SRC alone for complications (R2, 35.5% vs. 34.0%; p = 0.046). However, adding ASA-PS or TRISS to NSQIP-SRC did not improve the predictive ability for mortality or LOS.

CONCLUSION

The NSQIP-SRC, which includes comorbidities and functional status, had superior ability to predict mortality, LOS, and complications compared with TRISS alone in elderly trauma patients undergoing surgery.

Early rehabilitation after acute myocardial infarction: A nationwide inpatient database study

BACKGROUND

The effects and safety of early rehabilitation in intensive care units (ICU) remain unclear for patients after acute myocardial infarction (AMI).

METHODS

Using Japanese Diagnosis Procedure Combination inpatient data between July 2010 and March 2018, we identified 31,603 adult patients with AMI who underwent percutaneous coronary intervention on the day of admission and who were admitted to the ICU for more than three consecutive days. Patients who started a rehabilitation program within three days of ICU admission were included in the early rehabilitation group, while others were included in the usual care group. The primary outcome was activities of daily living (ADL) at discharge, as measured using the Barthel Index score. We conducted inverse probability of treatment weighting analyses.

RESULTS

The data of 31,603 patients were examined, 5,147 of whom were assigned to the early rehabilitation group. In the weighted cohort, the Barthel Index score at discharge was not significantly different between the two groups. The early rehabilitation group had a significantly shorter hospital stay, shorter ICU stay, and lower total hospitalization costs.

CONCLUSIONS

No correlations were observed between early rehabilitation and ADL at discharge. However, the present results suggest that early rehabilitation is safe and associated with lower hospital costs and shorter hospital stays after AMI.

A descriptive study on reasons for prolonged hospital stay in a tertiary hospital in Singapore

BACKGROUND

Our health care is facing with the challenges of bed crunch and increasing number of patients with prolonged hospital stay.

AIMS

This study aimed to determine factors contributing to the prolonged hospital stay in a tertiary hospital in Singapore.

METHODS

A random sample of 600 medical records of patients' staying in hospital for more than 21 days was retrieved. The reasons for their prolonged hospital stay were categorized into 'medically unfit' and 'medically fit'.

RESULTS

The top three reasons for prolonged hospital stay among the 'medically unfit' group were ongoing medical treatment, surgical interventions and receiving intravenous chemotherapy/radiotherapy. The top three reasons for the 'medically fit' group were waiting for community hospital bed, waiting for a new caregiver and undecided on discharge disposition.

CONCLUSION

The results inform health care stakeholders in planning measures to minimize the incidence of unnecessary prolonged hospitalization for optimal health care resource utilization.

IMPLICATIONS OF NURSING MANAGEMENT

Ineffective discharge planning can lead to serious adverse outcomes such as hospital readmission and prolonged hospital stay. Patient navigators have a crucial role in facilitating safe, smooth and timely discharge of patients from acute care hospital to community. Understanding the reasons behind extended hospitalization is essential in order to better provide support.

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.

Understanding health-care outcomes of older people with cognitive impairment and/or dementia admitted to hospital: a mixed-methods study

Background

Cognitive impairment is common in older people admitted to hospital, but previous research has focused on single conditions.

Objective

This project sits in phase 0/1 of the Medical Research Council Framework for the Development and Evaluation of Complex Interventions. It aims to develop an understanding of current health-care outcomes. This will be used in the future development of a multidomain intervention for people with confusion (dementia and cognitive impairment) in general hospitals. The research was conducted from January 2015 to June 2018 and used data from people admitted between 2012 and 2013.

Design

For the review of outcomes, the systematic review identified peer-reviewed quantitative epidemiology measuring prevalence and associations with outcomes. Screening for duplication and relevance was followed by full-text review, quality assessment and a narrative review (141 papers). A survey sought opinion on the key outcomes for people with dementia and/or confusion and their carers in the acute hospital (n = 78). For the analysis of outcomes including cost, the prospective cohort study was in a medical admissions unit in an acute hospital in one Scottish health board covering 10% of the Scottish population. The participants (n = 6724) were older people (aged ≥ 65 years) with or without a cognitive spectrum disorder who were admitted as medical emergencies between January 2012 and December 2013 and who underwent a structured nurse assessment. ‘Cognitive spectrum disorder’ was defined as any combination of delirium, known dementia or an Abbreviated Mental Test score of < 8 out of 10 points. The main outcome measures were living at home 30 days after discharge, mortality within 2 years of admission, length of stay, re-admission within 2 years of admission and cost.

Data sources

Scottish Morbidity Records 01 was linked to the Older Persons Routine Acute Assessment data set.

Results

In the systematic review, methodological heterogeneity, especially concerning diagnostic criteria, means that there is significant overlap in conditions of patients presenting to general hospitals with confusion. Patients and their families expect that patients are discharged in the same or a better condition than they were in on admission or, failing that, that they have a satisfactory experience of their admission. Cognitive spectrum disorders were present in more than one-third of patients aged ≥ 65 years, and in over half of those aged ≥ 85 years. Outcomes were worse in those patients with cognitive spectrum disorders than in those without: length of stay 25.0 vs. 11.8 days, 30-day mortality 13.6% vs. 9.0%, 1-year mortality 40.0% vs. 26.0%, 1-year mortality or re-admission 62.4% vs. 51.5%, respectively (all p < 0.01). There was relatively little difference by cognitive spectrum disorder type; for example, the presence of any cognitive spectrum disorder was associated with an increased mortality over the entire period of follow-up, but with different temporal patterns depending on the type of cognitive spectrum disorder. The cost of admission was higher for those with cognitive spectrum disorders, but the average daily cost was lower.

Limitations

A lack of diagnosis and/or standardisation of diagnosis for dementia and/or delirium was a limitation for the systematic review, the quantitative study and the economic study. The economic study was limited to in-hospital costs as data for social or informal care costs were unavailable. The survey was conducted online, limiting its reach to older carers and those people with cognitive spectrum disorders.

Conclusions

Cognitive spectrum disorders are common in older inpatients and are associated with considerably worse health-care outcomes, with significant overlap between individual cognitive spectrum disorders. This suggests the need for health-care systems to systematically identify and develop care pathways for older people with cognitive spectrum disorders, and avoid focusing on only condition-specific pathways.

Future work

Development and evaluation of a multidomain intervention for the management of patients with cognitive spectrum disorders in hospital.

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.

The prevalence and risk factors for urinary incontinence among inpatients, a multicenter study from Turkey

OBJECTIVE

To determine the prevalence and the factors associated with urinary incontinence (UI) among inpatients in Turkey.

METHOD

The population of this study comprised of patients screened by the "National Prevalence Measurement of Quality of Care (LPZ)" study in 2017 and 2018. Age, gender, comorbidities, length of hospital stay, sedative medications, SARC-F score, anthropometric measurements, and care parameters such as malnutrition, falls, UI-fecal incontinence (FI), restraints, and care dependency score (CDS) were noted. The LPZ questionnaire was performed by trained researchers, and multiple logistic regression analysis was performed to determine the factors associated with UI.

RESULTS

The prevalence of UI was 29.4 % among 1176 inpatients, and 41.6 % in patients ≥65 years. Urinary incontinence was associated with older age (OR, 1.966, 95 % CI 1.330-2.905), female sex (OR, 2.055, 95 % CI 1.393-3.030), CDS (OR, 3.236, 95 % CI 2.080-5.035), the number of comorbidities (OR, 1.312, 95 % CI 1.106-1.556), end-of life management (OR, 3.156, 95 % CI 1.412-7.052), sedative medications (OR, 1.981, 95 % CI 1.230-3.191), and FI (OR, 12.533, 95 % CI 4.892-32.112) in all adults, where CDS (OR, 2.589, 95% CI 1.458-4.599), end-of life management (OR, 2.851, 95 % CI 1.095-7.424), sedative medications (OR, 2.529, 95 % CI 1.406-4.548), and FI (OR, 13.138, 95 % CI 4.352-39.661) were associated with UI among geriatric patients.

CONCLUSIONS

The factors associated with UI in geriatric and all adult inpatients are CDS, sedative medications, end-of life management, and FI plus older age, female sex, and comorbidities for the latter. The factors associated with UI vary in different age groups.

Demographic Shifts, Case Mix, Activity, and Outcome for Elderly Patients Admitted to Adult General ICUs in England, Wales, and Northern Ireland

OBJECTIVES

Major increases in the proportion of elderly people in the population are predicted worldwide. These population increases, along with improving therapeutic options and more aggressive treatment of elderly patients, will have major impact on the future need for healthcare resources, including critical care. Our objectives were to explore the trends in admissions, resource use, and risk-adjusted hospital mortality for older patients, admitted over a 20-year period between 1997 and 2016 to adult general ICUs in England, Wales, and Northern Ireland.

DESIGN

RETROSPECTIVE ANALYSIS OF NATIONAL CLINICAL AUDIT DATABASE.

SETTING

The Intensive Care National Audit & Research Centre Case Mix Programme Database, the national clinical audit for adult general ICUs in England, Wales, and Northern Ireland.

PATIENTS

All adult patients 16 years old or older admitted to adult general ICUs contributing data to the Case Mix Programme Database between January 1, 1997, and December 31, 2016.

MEASUREMENTS AND MAIN RESULTS

The annual number, trends, and outcomes for patients across four age bands (16-64, 65-74, 75-84, and 85+ yr) admitted to ICUs contributing to the Case Mix Programme Database from 1997 to 2016 were examined. Case mix, activity, and outcome were described in detail for the most recent cohort of patients admitted in 2015-2016. Between 1997 to 2016, the annual number of admissions to ICU of patients in the older age bands increased disproportionately, with increases that could not be explained solely by general U.K. demographic shifts. The risk-adjusted acute hospital mortality decreased significantly within each age band over the 20-year period of the study. Although acute severity at ICU admission was comparable with that of the younger age group, apart from cardiovascular and renal dysfunction, older patients received less organ support. Older patients stayed longer in hospital post-ICU discharge, and hospital mortality increased with age, but the majority of patients surviving to hospital discharge returned home.

CONCLUSIONS

Over the past two decades, elderly patients have been more commonly admitted to ICU than can be explained solely by the demographic shift. Importantly, as with the wider population, outcomes in elderly patients admitted to ICU are improving over time, with most patients returning home.

Association of Geriatric Syndromes with Urinary Incontinence according to Sex and Urinary-Incontinence-Related Quality of Life in Older Inpatients: A Cross-Sectional Study of an Acute Care Hospital

Background

Geriatric syndromes are associated with morbidity and poor quality of life (QOL). Urinary incontinence (UI) is one of the most prevalent geriatric syndromes. However, there is little research on the association of UI and UI-related QOL with other geriatric syndromes. We investigated the relationship between geriatric syndromes and UI according to gender and UI-related QOL among older inpatients.

Methods

This study was conducted among 444 older inpatients (aged 65 years and older) between October 2016 and July 2017. We examined geriatric syndromes and related factors involving cognitive impairment, delirium, depression, mobility decline, polypharmacy, undernutrition, pain, and fecal incontinence. UI-related QOL was assessed using the International Consultation on Incontinence Questionnaire-Short Form. Multiple logistic regression analysis was used to evaluate these associations.

Results

Geriatric syndromes and related factors were associated with UI. Mobility decline (odds ratio [OR], 4.16; 95% confidence interval [CI], 2.29–7.56), polypharmacy (OR, 3.35; 95% CI, 1.89–5.92), and pain (OR, 6.80; 95% CI, 3.53–13.09) were related to UI in both genders. Especially, delirium (OR, 7.55; 95% CI, 1.61–35.44) and fecal incontinence (OR, 10.15; 95% CI, 2.50–41.17) were associated with UI in men, while cognitive impairment (OR, 4.19; 95% CI, 1.14–15.44) was significantly associated with UI in women. Patients with depression were more likely to have poor UI-related QOL (OR, 8.54; 95% CI, 1.43–51.15).

Conclusion

UI was associated with different geriatric syndromes and related factors according to gender. Care for patients with depression, related to poor UI-related QOL, should be considered in primary care to improve the UI-related QOL of these individuals.

The proactive elderly care team: dementia screening of over 20 000 patients

The proactive elderly care team was introduced at Lancashire Teaching Hospitals NHS Foundation Trust in October 2012. This article describes how the team performed over 5 years (up to the end of December 2017). The proactive elderly care team had three broad aims related to all non-elective patients over the age of 75 years who either came to accident and emergency or were admitted into the hospital, irrespective of speciality: To screen all patients over the age of 75 years for delirium and dementia To identify patients over 75 years who were the most frail, and would benefit from a comprehensive geriatric assessment and targeted interventions To reduce length of stay for patients over the age of 75 years without any increase in their readmission rate. Following the introduction of the proactive elderly care team, length of stay and the readmission rate of patients who were seen by the service fell by about 50%. Almost £10 million has been saved and for every £1 invested in the proactive elderly care team service, over £12 was saved.

Screening for older inpatients at risk for long length of stay: which clinical tool to use?

Background

Screening for inpatients at risk for long length of stay (LOS) is the first step of an effective hospital care plan for older inpatients. This study aims, in older adults admitted to a geriatric acute care ward, to examine and compare the 6-item brief geriatric assessment (BGA) and the “Programme de Recherche sur l’Intégration des Services pour le Maintien de l’Autonomie” (PRISMA-7) risk levels with long LOS, and to establish their performance criteria (i.e., sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratios) for LOS.

Methods

Based on an observational, retrospective, cohort design, 166 inpatients aged ≥75 admitted to a geriatric acute care ward of a McGill University-affiliated hospital (Montreal, Quebec, Canada) were recruited. The risk levels of the 6-item BGA (low, moderate and high) and the PRISMA-7 (low versus high) were calculated from a baseline assessment. The LOS was subsequently calculated in number of days.

Results

Only the 6-item BGA high risk level was associated with a long LOS (Odds ratio = 1.1 with P = 0.028 and Hazard ratio = 2.1 with P = 0.004). Kaplan-Meier distributions showed that there was no significant difference in the delay of hospital discharge between the low and high-risk level reported by the PRISMA-7 (P = 0.381), whereas the 6-item BGA three risk levels differed significantly (P = 0.008), with individuals at high risk levels being discharged later when compared to those with low (P = 0.001) and moderate (P = 0.019) risk levels. Both tools’ performance criteria were poor (i.e., < 0.70), except for PRISMA-7’s sensitivity which was 100%.

Conclusion

The 6-item BGA risk levels were associated with LOS, low risk-level being associated with short LOS and high-risk level with long LOS, but no association was reported with the PRISMA-7 risk levels. Both tools had poor performance criteria for long LOS, suggesting that they cannot be used as prognostic tools with current scientific knowledge.

Chronic neurological disorders and related comorbidities: Role of age-associated physiological changes

Current knowledge indicates that the physiological aging process starts with subclinical changes at the molecular and cellular level, which affect nearly all physiological systems. For example, the age-associated remodeling of the immune system (i.e., immunosenescence) and vascular aging per se can contribute to frailty and vulnerability among older adults. They are also described as being implicated in the pathophysiology of some major chronic comorbid conditions such as age-associated diseases of the central (e.g., stroke, Parkinson's disease, Alzheimer's disease, and related disorders) and peripheral (e.g., polyneuropathy) nervous systems. These neurologic disorders are also among the greatest contributors to geriatric syndromes, which refer to highly prevalent and chronic conditions among aged people of multifactorial origin, such as delirium, falls, incontinence, and frailty. Neurologic disorders can also occur in patients with one or more geriatric syndromes and thus further interfere with the quality of life, physical function, morbidity, and mortality. This chapter presents and discusses in three sections the complex interrelationships between the main determinants of aging with a specific focus on vascular aging, chronic neurologic disorders, and the specific clinical presentation of geriatric syndromes in older people.

Screening for urinary incontinence in acute care for elders unit: comparative performance analysis of Katz's ADL and ICIQ-UI-SF

BACKGROUND

Urinary incontinence (UI) is a frequent, but neglected geriatric syndrome, particularly in vulnerable older patients. Optimizing screening procedures is necessary.

OBJECTIVE

To compare the clinometric performances of the "continence" item of the Katz's ADL scale and the ICIQ-UI-sf for the screening of UI in vulnerable aged patients.

METHODS

A prospective study was conducted in the acute care for elders (ACE) unit of an academic centre. Two independent nurses screened all patients with spontaneous urination for UI with Katz's ADL item and ICIQ-UI-sf upon the hospital admission. The diagnosis of UI resulted from an interdisciplinary conciliating meeting for urinary functional disorders (TOFU), gathering geriatricians and neuro-urologists and was considered as reference.

RESULTS

294 consecutive patients (mean age 86.2 ± 6.5 years; 76.5% female) admitted to the ACE unit were screened; 169 were incontinent (57.5%) according to TOFU. The Katz's ADL item identified 106 incontinent patients with 20 false positives; 83 incontinent patients were not identified. If the sensitivity and specificity of the ICIQ-UI-sf were 100.0%, they were, respectively, 50.9 and 84.0% for the Katz's ADL item. Positive and negative predictive values were 100.0% for ICIQ-UI-sf; 81.1 and 55.9% for ADL, respectively.

CONCLUSION

This study validates the ICIQ-UI-sf as a simple and effective screening tool for UI in vulnerable and complex hospitalized aged patients. It also demonstrates that the "continence" item of the Katz's ADL scale is not sensitive enough for UI screening in this population.

Predicting a long hospital stay after admission to a geriatric assessment unit: Results from an observational retrospective cohort study

OBJECTIVE

Morbidities and related disabilities often lead to older inpatients having a long hospital stay. The aim of this study was to examine whether the 6-item brief geriatric assessment (BGA), developed and validated in France to determine a priori levels of risk of a long hospital stay (i.e.; low, moderate, high), could be successfully used with patients admitted to a geriatric assessment unit (GAU) in Quebec.

STUDY DESIGN

Observational retrospective cohort design.

SETTING

A GAU of a McGill University affiliated hospital (Montreal, Quebec, Canada).

PARTICIPANTS

499 inpatients (84.7 ± 7.2 years; 73.3% female) recruited upon their admission.

MAIN OUTCOME MEASURES

The BGA comprises 6 items: age > 85 years, male gender, ≥ 5 drugs per day, use of home-help support, history of falls and temporal disorientation. It was administered at baseline and a priori levels of risk of a long hospital stay (i.e., low, moderate, high) were determined. Length of hospital stay (LHS, in days) was calculated using the hospital registry. The association between a priori levels of risk from the BGA and LSH was examined using regression models and Kaplan-Meier curves.

RESULTS

The LHS increased with the 6-item BGA a priori level of risk (P = 0.010). High-risk (Hazard ratio (HR) = 1.68 with P < 0.001) and moderate-risk (HR = 1.24 with P = 0.039) of a long hospital stay successfully predicted a long stay. Kaplan-Meier distributions of time to discharge showed that inpatients classified as having high and moderate risk levels for a long hospital stay were discharged later than those with a low risk level (P < 0.001 and P = 0.013).

CONCLUSION

The 6-item BGA a priori levels of risk for a long hospital stay successfully predicted a long stay among patients admitted to a GAU in Quebec.

Hospital outcomes of older people with cognitive impairment: An integrative review

OBJECTIVES

To summarise existing knowledge of outcomes of older hospital patients with cognitive impairment, including the type and frequency of outcomes reported, and the additional risk experienced by this patient group.

METHODS

Integrative literature review. Health care literature databases, reports, and policy documents on key websites were systematically searched. Papers describing the outcomes of older people with cognitive impairment during hospitalisation and at discharge were analysed and summarised using integrative methods.

RESULTS

One hundred four articles were included. A range of outcomes were identified, including those occurring during hospitalisation and at discharge. Older people with a dementia diagnosis were at higher risk from death in hospital, nursing home admission, long lengths of stay, as well as intermediate outcomes such as delirium, falls, dehydration, reduction in nutritional status, decline in physical and cognitive function, and new infections in hospital. Fewer studies examined the relationship of all-cause cognitive impairment with outcomes. Patient and carer experiences of hospital admission were often poor. Few studies collected data relating to hospital environment, eg, ward type or staffing levels, and acuity of illness was rarely described.

CONCLUSIONS

Older people with cognitive impairment have a higher risk of a variety of negative outcomes in hospital. Prevalent intermediate outcomes suggest that changes in care processes are required to ensure maintenance of fundamental care provision and greater attention to patient safety in this vulnerable group. More research is required to understand the most appropriate ways of doing this and how changes in these care processes are best implemented to improve hospital outcomes.

Functional deterioration in the month before hospitalisation is associated with in-hospital functional decline: an observational study

INTRODUCTION

Functional deterioration preceding acute hospital admission may be associated with poorer in-hospital outcomes. We sought to investigate the association between functional decline in the month preceding admission and in-hospital outcomes.

MATERIALS AND METHODS

Consecutive patients admitted under geriatric medicine over 5 years were prospectively included. Pre-hospital decline was defined as decrease in Modified Barthel Index (MBI) between pre-morbid status (1 month prior) and admission. The primary outcome was in-hospital functional decline (decline in MBI and/or new assistance/aid to mobilise). Secondary outcomes included length-of-stay (LOS; highest quartile), in-hospital falls and death.

RESULTS

Amongst 1458 patients (mean age 82.0; 60.91% female), 76.89% (1121/1458) experienced pre-hospital MBI decline. On univariate logistic regression, pre-hospital MBI decline was associated with in-hospital functional decline (OR 15.83, p < 0.001). Adjusting for age, nursing home residence, pre-morbid MBI, in-hospital referral source, dementia, adverse drug reaction and number of active diagnoses, pre-hospital decline was independently associated with in-hospital functional decline (OR 15.22, CI 10.89-21.26, p < 0.001). On univariate analysis, those with pre-hospital decline had more in-hospital falls (OR 2. 91, p = 0.02). Adjusting for age, sex, dementia, number of active diagnoses, and ambulation, no strong association was observed between pre-hospital decline and in-hospital falls (OR 1.86, p = 0.08). Prolonged LOS ≥ 20 days was more common amongst patients with pre-hospital decline on univariate (OR 1.95, p < 0.001) but not adjusted analyses (p = 0.14). No association was observed with in-hospital death.

CONCLUSION

Pre-hospital functional decline was associated with poorer in-hospital functional outcomes. Exploration of early interventions to optimise function in such patients is needed.

Accelerometry Shows Inpatients With Acute Medical or Surgical Conditions Spend Little Time Upright and Are Highly Sedentary: Systematic Review

BACKGROUND

Physical inactivity and sedentary behaviors have significant and independent effects on health. The use of wearable monitors to measure these constructs in people who are hospitalized with an acute illness is rapidly expanding, but has not been systematically described.

PURPOSE

The purpose of this study was to review the use of accelerometer monitoring with inpatients who are acutely ill, including what activity and sedentary behaviors have been measured and how active or sedentary inpatients are.

DATA SOURCES

Databases used were MEDLINE, EMBASE, CINAHL, and Scopus.

STUDY SELECTION

Quantitative studies of adults with an acute medical or surgical hospital admission, on whom an accelerometer was used to measure a physical activity or sedentary behavior, were selected.

DATA EXTRACTION AND DATA SYNTHESIS

Procedures were completed independently by 2 reviewers, with differences resolved and cross-checked by a third reviewer. Forty-two studies were identified that recruited people who had medical diagnoses (n = 10), stroke (n = 5), critical illness (n = 3), acute exacerbations of lung disease (n = 7), cardiac conditions (n = 7), or who were postsurgery (n = 10). Physical activities or sedentary behaviors were reported in terms of time spent in a particular posture (lying/sitting, standing/stepping), active/inactive, or at a particular activity intensity. Physical activity was also reported as step count, number of episodes or postural transitions, and bouts. Inpatients spent 93% to 98.8% (range) of their hospital stay sedentary, and in most studies completed <1,000 steps/day despite up to 50 postural transitions/day. No study reported sedentary bouts. Many studies controlled for preadmission function as part of the recruitment strategy or analysis or both.

LIMITATIONS

Heterogeneity in monitoring devices (17 models), protocols, and variable definitions limited comparability between studies and clinical groups to descriptive synthesis without meta-analysis.

CONCLUSIONS

Hospitalized patients were highly inactive, especially those with medical admissions, based on time and step parameters. Accelerometer monitoring of sedentary behavior patterns was less reported and warrants further research.

Dementia and co-occurring chronic conditions: a systematic literature review to identify what is known and where are the gaps in the evidence?

OBJECTIVE

The challenges posed by people living with multiple chronic conditions are unique for people with dementia and other significant cognitive impairment. There have been recent calls to action to review the existing literature on co-occurring chronic conditions and dementia in order to better understand the effect of cognitive impairment on disease management, mobility, and mortality.

METHODS

This systematic literature review searched PubMed databases through 2011 (updated in 2016) using key constructs of older adults, moderate-to-severe cognitive impairment (both diagnosed and undiagnosed dementia), and chronic conditions. Reviewers assessed papers for eligibility and extracted key data from each included manuscript. An independent expert panel rated the strength and quality of evidence and prioritized gaps for future study.

RESULTS

Four thousand thirty-three articles were identified, of which 147 met criteria for review. We found that moderate-to-severe cognitive impairment increased risks of mortality, was associated with prolonged institutional stays, and decreased function in persons with multiple chronic conditions. There was no relationship between significant cognitive impairment and use of cardiovascular or hypertensive medications for persons with these comorbidities. Prioritized areas for future research include hospitalizations, disease-specific outcomes, diabetes, chronic pain, cardiovascular disease, depression, falls, stroke, and multiple chronic conditions.

CONCLUSIONS

This review summarizes that living with significant cognitive impairment or dementia negatively impacts mortality, institutionalization, and functional outcomes for people living with multiple chronic conditions. Our findings suggest that chronic-disease management interventions will need to address co-occurring cognitive impairment. Copyright © 2017 John Wiley & Sons, Ltd.

Structured interdisciplinary bedside rounds do not reduce length of hospital stay and 28-day re-admission rate among older people hospitalised with acute illness: an Australian study

Objective Structured interdisciplinary bedside rounds (SIBR) are being implemented across many hospitals in Australia despite limited evidence of their effectiveness. This study evaluated the effect of SIBR on two interconnected outcomes, namely length of stay (LOS) and 28-day re-admission. Methods In the present before-after study of 3644 patients, twice-weekly SIBR were implemented on two aged care wards. Although weekly case conferences were shortened during SIBR, all other practices remained unchanged. Demographic, medical and frailty measures were considered in appropriate analyses. Results There was no significant difference in median (interquartile range) LOS before and during SIBR (8 (5–15) vs 8 (4–15) days respectively; P = 0.51). In an adjusted analysis, SIBR had no effect on LOS (hazard ratio 0.97; 95% confidence interval 0.90–1.05). The presence of dementia or delirium, or the ability to speak English, did not modify the effect of SIBR (P > 0.05 for all). Similarly, SIBR had no effect on 28-day re-admission rates (20.3% vs 19.0% before and during SIBR respectively; P = 0.36). Conclusions Although ineffective interdisciplinary communication is associated with negative outcomes for patients and healthcare services, models of care that aim to improve communication are not necessarily effective in reducing LOS or early re-admission. Clinical services implementing SIBR are encouraged to independently evaluate their effects. What is known about the topic? Ineffective interdisciplinary communication may harm patients and increase LOS. Only two publications have evaluated the implementation of SIBR, a new model of care that aims to improve interdisciplinary communication and collaboration. One paper reported that SIBR reduced unadjusted LOS and in-hospital mortality, whereas the other found that SIBR improved teamwork, communication and staff efficiency. What does this paper add? The effect of SIBR among acutely unwell older people on aged care wards is unknown. The present study is the first to evaluate the effects of SIBR in this population. It shows that the implementation of SIBR did not reduce LOS or early re-admission, and suggests that existing communication strategies may have weakened the effects of SIBR. What are the implications for practitioners? Policies and practice that promote the addition of communication strategies, such as SIBR, may not be effective in all patient populations. More research is needed to determine whether SIBR reduce these and other outcomes, particularly for services with weaker communication frameworks and protocols.

[Reduction of rehospitalisation on elderly heart failure patients: A retrospective cohort VISage network]

BACKGROUND

Heart failure was a public health problem for one million of French patients. Patients are particularly concerned in rehospitalisation for this chronic pathology. A specific healthcare network was created to take care of patients with heart failure directly at home. This healthcare network (named VISage) brings a specific and adapted monitoring in heart failure. The main of this study was to evaluate the impact of healthcare network in rehospitalisation rate for heart failure of patients.

MATERIAL AND METHODS

We conducted a retrospective cohort study with patients' hospital files of the CH Vienne. Patients who were included in our healthcare network (VISage) were screened. Primary endpoint was 30days, 6 months, and 1year rehospitalisation rate for heart failure before and after using healthcare network.

RESULTS

One hundred and four patients with comorbidities were included between February 2009 and November 2015. A significant reduction of rehospitalisation rate for heart failure was observed before and after network: 0.65 (±0.52) vs. 0.17 (±0.43) 30days, 1.17 (±0.74) vs. 0.42 (±0.71) at 6 months and 1.35 (±0.95) vs. 0.47 (±0.74) at 1 year (P<0.0001). Results were significant for global rehospitalisation rate too. No significant differences were shown on hospital length of stay.

CONCLUSION

Coordinated healthcare by a specific network at home for elderly is benefic for the rehospitalisation rate.

Factors associated with prolonged length of stay in older patients

INTRODUCTION

Prolonged stay in acute hospitals increases the risk of hospital-acquired infections in older patients, and disrupts patient flow and access to care due to bed shortages. We aimed to investigate the factors associated with prolonged length of stay (pLOS) among older patients (aged ≥ 78 years) in a tertiary hospital, to identify the potentially modifiable risk factors that could direct interventions to reduce length of stay (LOS).

METHODS

During a three-month period from January 2013 to March 2013, we identified 72 patients with pLOS (LOS ≥ 21 days) and compared their demographic and clinical variables with that of 281 randomly selected control patients (LOS < 21 days) using univariate and multivariate logistic regression analyses.

RESULTS

The mean age of the patients was 85.30 ± 5.34 years; 54% of them were female and 72% were of Chinese ethnicity. Logistic regression revealed the following significant factors for increased LOS: discharge to intermediate and long-term care services (odds ratio [OR] 9.22, 95% confidence interval [CI] 3.56-23.89; p < 0.001); increased severity of illness (OR 2.41, 95% CI 1.12-5.21; p = 0.025); and presence of caregiver stress (OR 3.85, 95% CI 1.67-8.91; p = 0.002).

CONCLUSION

Presence of caregiver stress and nursing home placement are potential modifiable risk factors of pLOS among older patients. Early identification and management of caregiver stress, as well as expediting discharge planning, may help to reduce the length of stay for this cohort.

The Impact of Admission Diagnosis on Recurrent or Frequent Hospitalizations in 3 Dementia Subtypes: A Hospital-Based Cohort in Taiwan with 4 Years Longitudinal Follow-Ups

Increasing numbers of patients with different types of dementia have resulted in the increasing medical care loads. It is not known whether explanatory factors for recurrent or prolong hospitalization were driven by the subtypes of dementia. We analyzed 203 dementia patients aged >65-year-old with a clinical diagnosis of Alzheimer disease (AD), vascular dementia (VaD), or Parkinsonism-related dementia (PRD). With a 4-year follow-up period, logistic regression analyses were used to identify predictors of dementia diagnosis, cerebrovascular risk factors, chronic systemic diseases, and the etiology for admission for recurrent (>4 times/4 years) or prolonged hospitalization stay (>14 days per hospitalization). There were 48 AD, 96 VaD, and 59 PRD patients that completed the 4-year study. The average length of hospital stay was significant, the shortest in AD and the longest in PRD (P = 0.01), whereas the frequency of hospitalization was not different among 3 dementia subtypes. Although delirium is the most common etiology for admission in the patients, diabetes mellitus (Odds ratio, OR = 2.79, P = 0.02), pneumonia (OR = 11.21, P < 0.001), and fall-related hip fracture (OR = 4.762, P = 0.029) were significantly associated with prolong hospitalization. Patients with coronary artery disease (OR = 9.87, P = 0.02), pneumonia (OR = 84.48, P < 0.001), urinary tract infection (OR = 55.09, P < 0.001), and fall-related fracture (OR = 141.7, P < 0.001) predict recurrent hospitalization. Dementia subtypes did not influence directly on the hospitalization courses. The etiologies for admission carried higher clinical significance, compared with the coexisted systemic diseases.

Impact of a person-centred dementia care training programme on hospital staff attitudes, role efficacy and perceptions of caring for people with dementia: A repeated measures study

BACKGROUND

People with dementia occupy up to one quarter of acute hospital beds. However, the quality of care delivered to this patient group is of national concern. Staff working in acute hospitals report lack of knowledge, skills and confidence in caring for people with dementia. There is limited evidence about the most effective approaches to supporting acute hospital staff to deliver more person-centred care.

OBJECTIVES

This study aimed to evaluate the efficacy of a specialist training programme for acute hospital staff regarding improving attitudes, satisfaction and feelings of caring efficacy, in provision of care to people with dementia.

DESIGN

A repeated measures design, with measures completed immediately prior to commencing training (T1), after completion of Foundation level training (T2: 4-6 weeks post-baseline), and following Intermediate level training (T3: 3-4 months post-baseline).

SETTING

One NHS Trust in the North of England, UK.

PARTICIPANTS

40 acute hospital staff working in clinical roles, the majority of whom (90%) were nurses.

METHODS

All participants received the 3.5 day Person-centred Care Training for Acute Hospitals (PCTAH) programme, comprised of two levels, Foundation (0.5 day) and Intermediate (3 days), delivered over a 3-4 months period. Staff demographics and previous exposure to dementia training were collected via a questionnaire. Staff attitudes were measured using the Approaches to Dementia Questionnaire (ADQ), satisfaction in caring for people with dementia was captured using the Staff Experiences of Working with Demented Residents questionnaire (SEWDR) and perceived caring efficacy was measured using the Caring Efficacy Scale (CES).

RESULTS

The training programme was effective in producing a significant positive change on all three outcome measures following intermediate training compared to baseline. A significant positive effect was found on the ADQ between baseline and after completion of Foundation level training, but not for either of the other measures.

CONCLUSIONS

Training acute hospital staff in Intermediate level person-centred dementia care is effective in producing significant improvements in attitudes towards and satisfaction in caring for people with dementia and feelings of caring efficacy. Foundation level training is effective in changing attitudes but does not seem to be sufficient to bring about change in satisfaction or caring efficacy.

French Multicenter Evaluation of the Appropriateness of Admission to the Emergency Department of the Over-80s

BACKGROUND

Persons over 80 represents 40% of patients in French emergency services. We assessed the appropriateness of these admissions and sought to identify risk factors for inappropriate hospital stays.

METHODS

The appropriateness of admission was assessed in a prospective, cross-sectional, multicenter study in eight hospitals in France by means of the Appropriateness Evaluation Protocol (French version, AEPf) during two non-consecutive periods of four weeks in 2010. We analyzed admission of patients aged 80 and over who were admitted to the hospital after a stay in the emergency department of the same hospital. Demographics and morbidity factors were recorded as were administrative hospitalization data to identify risk factors associated with inappropriate admissions. We also evaluated the economic impact of inappropriate admissions. For cost analysis, all variables were obtained from anonymized hospital reports of a diagnosis-related group system used for funding of the hospitals by health insurance.

RESULTS

During two different periods, 1577 patients were included. 139 (8.8%) hospital admissions were inappropriate according to explicit criteria of the AEPf, but 18 of these (1.1%) were in fact considered appropriate by the physician responsible for the admission, leading to 121 (7.7%) inappropriate admissions. Multivariate logistic regression showed that patients with heart disease were less often subject to inappropriate admission (odds ratio OR= 0.36 [0.23; 0.56], p < 0.001), as also were patients who usually lived in a nursing home (OR = 0.53 [0.30; 0.87], p = 0.018) and patients with higher Acute Physiology Scores (OR = 0.97 [0.95; 0.99], p < 0.001). Inappropriate admission increased when patients had a syndrome as the main diagnosis (OR = 1.81 [1.81; 2.83], p = 0.010). By contrast, cognitive functions, gait and balance disturbance or falls, behavioral disorders and method of transport to the emergency department did not change the probability of inappropriateness. The median cost of the hospital stay of an older patient was 3 606.5 [2 498.1; 4 994.2] euros for inappropriate admissions.

CONCLUSION

Inappropriate emergency admissions of older patients were infrequent. None of the geriatric syndromes were linked with the phenomenon and principle causes were severity of illness, mention of a cardiac disease, unclear pattern of consultation and institutionalized way of life.

Exploring the cost-effectiveness of a one-off screen for dementia (for people aged 75 years in England and Wales)

OBJECTIVE

This paper examines the numbers of people with dementia who could be diagnosed and the likely cost-effectiveness of a one-off screen for dementia for people aged 75 years in England and Wales.

METHODS

The study uses static decision modelling to compare a one-off screen for dementia with a no-screen scenario. Estimates for the model were drawn from systematic reviews, high-quality studies and government and administrative sources. A panel of experts also advised the study.

RESULTS

An estimated 3514 people could be diagnosed as a result of screening, 2152 of whom would otherwise never receive a diagnosis. The study identified societal economic impact of between £3,649,794 (net costs) and £4,685,768 (net savings), depending on assumptions.

CONCLUSIONS

Our analysis suggests that screening could be cost-effective, especially as treatments and social care interventions become more effective and if diagnosis by current routes remains low or occurs later than is optimal. This study was, however, limited by available evidence and a range of quality of life benefits, cost savings and potential harms could not be quantified. It was also beyond the scope of this study to consider dynamic factors such as repeat screening, mortality, disease trajectories or trends in the numbers of people with dementia. A larger study would be needed for this, involving more complex and innovative approaches to generating estimates for modelling. We did not compare population screening for people aged 75 years to other methods for increasing diagnosis rates.

Burden, causes, and outcomes of people with epilepsy admitted to a rural hospital in Kenya

OBJECTIVE

People with epilepsy (PWE) develop complications and comorbidities often requiring admission to hospital, which adds to the burden on the health system, particularly in low-income countries. We determined the incidence, disability-adjusted life years (DALYs), risk factors, and causes of admissions in PWE. We also examined the predictors of prolonged hospital stay and death using data from linked clinical and demographic surveillance system.

METHODS

We studied children and adults admitted to a Kenyan rural hospital, between January 2003 and December 2011, with a diagnosis of epilepsy. Poisson regression was used to compute incidence and rate ratios, logistic regression to determine associated factors, and the DALY package of the R-statistical software to calculate years lived with disability (YLD) and years of life lost (YLL).

RESULTS

The overall incidence of admissions was 45.6/100,000 person-years of observation (PYO) (95% confidence interval [95% CI] 43.0-48.7) and decreased with age (p < 0.001). The overall DALYs were 3.1/1,000 (95% CI, 1.8-4.7) PYO and comprised 55% of YLD. Factors associated with hospitalization were use of antiepileptic drugs (AEDs) (odds ratio [OR] 5.36, 95% CI 2.64-10.90), previous admission (OR 11.65, 95% CI 2.65-51.17), acute encephalopathy (OR 2.12, 95% CI 1.07-4.22), and adverse perinatal events (OR 2.87, 95% CI 1.06-7.74). Important causes of admission were epilepsy-related complications: convulsive status epilepticus (CSE) (38%), and postictal coma (12%). Age was independently associated with prolonged hospital stay (OR 1.02, 95% CI 1.00-1.04) and mortality (OR, 1.07, 95% CI 1.04-1.10).

SIGNIFICANCE

Epilepsy is associated with significant number of admissions to hospital, considerable duration of admission, and mortality. Improved supply of AEDs in the community, early initiation of treatment, and adherence would reduce hospitalization of PWE and thus the burden of epilepsy on the health system.

Identifying clusters of falls-related hospital admissions to inform population targets for prioritising falls prevention programmes

BACKGROUND

There has been limited research investigating the relationship between injurious falls and hospital resource use. The aims of this study were to identify clusters of community-dwelling older people in the general population who are at increased risk of being admitted to hospital following a fall and how those clusters differed in their use of hospital resources.

METHODS

Analysis of routinely collected hospital admissions data relating to 45 374 fall-related admissions in Victorian community-dwelling older adults aged ≥65 years that occurred during 2008/2009 to 2010/2011. Fall-related admission episodes were identified based on being admitted from a private residence to hospital with a principal diagnosis of injury (International Classification of Diseases (ICD)-10-AM codes S00 to T75) and having a first external cause of a fall (ICD-10-AM codes W00 to W19). A cluster analysis was performed to identify homogeneous groups using demographic details of patients and information on the presence of comorbidities. Hospital length of stay (LOS) was compared across clusters using competing risks regression.

RESULTS

Clusters based on area of residence, demographic factors (age, gender, marital status, country of birth) and the presence of comorbidities were identified. Clusters representing hospitalised fallers with comorbidities were associated with longer LOS compared with other cluster groups. Clusters delineated by demographic factors were also associated with increased LOS.

CONCLUSIONS

All patients with comorbidity, and older women without comorbidities, stay in hospital longer following a fall and hence consume a disproportionate share of hospital resources. These findings have important implications for the targeting of falls prevention interventions for community-dwelling older people.

A multicomponent approach to identify predictors of hospital outcomes in older in-patients: a multicentre, observational study

Background

The identification of older patients at risk of poor hospital outcomes (e.g. longer hospital stay, in-hospital mortality, and institutionalisation) is important to provide an effective healthcare service.

Objective

To identify factors related to older patients’ clinical, nutritional, functional and socio-demographic profiles at admission to an acute care ward that can predict poor hospital outcomes.

Design and Setting

The CRiteria to assess appropriate Medication use among Elderly complex patients project was a multicentre, observational study performed in geriatric and internal medicine acute care wards of seven Italian hospitals.

Subjects

One thousand one hundred twenty-three consecutively admitted patients aged 65 years or older.

Methods

Hospital outcomes were length of stay, in-hospital mortality, and institutionalisation.

Results

Mean age of participants was 81 years, 56% were women. Median length of stay was 10 (7–14) days, 41 patients died during hospital stay and 37 were newly institutionalised. Number of drugs before admission, metastasized cancer, renal failure or dialysis, infection, falls at home during the last year, pain, and walking speed were independent predictors of LoS. Total dependency in activities of daily living and inability to perform grip strength test were independent predictors of in-hospital mortality. Malnutrition and total dependency in activities of daily living were independent predictors of institutionalisation.

Conclusions

Our results confirm that not only diseases, but also multifaceted aspects of ageing such as physical function and malnutrition are strong predictors of hospital outcomes and suggest that these variables should be systematically recorded.

Screening for older emergency department inpatients at risk of prolonged hospital stay: the brief geriatric assessment tool

BACKGROUND

The aims of this study were 1) to confirm that combinations of brief geriatric assessment (BGA) items were significant risk factors for prolonged LHS among geriatric patients hospitalized in acute care medical units after their admission to the emergency department (ED); and 2) to determine whether these combinations of BGA items could be used as a prognostic tool of prolonged LHS.

METHODS

Based on a prospective observational cohort design, 1254 inpatients (mean age ± standard deviation, 84.9±5.9 years; 59.3% female) recruited upon their admission to ED and discharged in acute care medical units of Angers University Hospital, France, were selected in this study. At baseline assessment, a BGA was performed and included the following 6 items: age ≥85years, male gender, polypharmacy (i.e., ≥5 drugs per day), use of home-help services, history of falls in previous 6 months and temporal disorientation (i.e., inability to give the month and/or year). The LHS in acute care medical units was prospectively calculated in number of days using the hospital registry.

RESULTS

Area under receiver operating characteristic (ROC) curves of prolonged LHS of different combinations of BGA items ranged from 0.50 to 0.57. Cox regression models revealed that combinations defining a high risk of prolonged LHS, identified from ROC curves, were significant risk factors for prolonged LHS (hazard ratio >1.16 with P>0.010). Kaplan-Meier distributions of discharge showed that inpatients classified in high-risk group of prolonged LHS were discharged later than those in low-risk group (P<0.003). Prognostic value for prolonged LHS of all combinations was poor with sensitivity under 77%, a high variation of specificity (from 26.6 to 97.4) and a low likelihood ratio of positive test under 5.6.

CONCLUSION

Combinations of 6-item BGA tool were significant risk factors for prolonged LHS but their prognostic value was poor in the studied sample of older inpatients.

Is obesity a marker of robustness in vulnerable hospitalized aged populations? Prospective, multicenter cohort study of 1 306 acutely ill patients

BACKGROUND

The "obesity paradox" is poorly understood in vulnerable older hospitalized populations.

OBJECTIVES

To prospectively analyze the impact of body mass index (BMI) and comorbidities on early (6-week), one- and two-year mortality.

DESIGN

Prospective multicenter study with a two-year follow-up of old patients participating in the SAFES cohort study.

SETTINGS

Nine university hospitals in France.

PARTICIPANTS

Patients aged 75 or older hospitalized in medical divisions through the emergency department.

MEASUREMENT

Inpatients' characteristics were obtained through a comprehensive geriatric assessment of inpatients, conducted in the first week of hospitalization. All-cause mortalities at 6-week, one- and two-year were determined using bivariable and multivariable Cox proportional hazard model.

RESULTS

The SAFES cohort included 1,306 patients, aged 85±6 years, with a majority of women (65%). One- and two-year mortality were inversely associated with BMI ≥30 kg/m2 while early mortality was not, and positively associated with age, burden of comorbidities, walking disorders, level of dependency and presence of a dementia syndrome. Survival rates between patients in low (< 18.0 kg/m2) and intermediate (18-24.9 and 25-29.9 kg/m2) BMI categories were not significant.

CONCLUSION

While our findings seem to confirm the reality of the "obesity paradox" in vulnerable older hospitalized population, the exact understanding of underlying mechanisms and even the truthfulness of this paradoxical relationship are still fraught with considerable methodological, epidemiological and metabolic challenges.

Impact of a mandatory geriatric medicine clerkship on the care of older acute medical patients: a retrospective cohort study

BACKGROUND

The impact of geriatric medicine educational programs on patient level outcomes, as opposed to educational measures, is not well studied. We aimed to determine whether completion of a mandatory geriatrics rotation changed the clinical behaviors of clerks caring for older patients admitted to a medical clinical teaching unit.

METHODS

We reviewed the charts of 132 older (>70y) patients, admitted to one medical clinical teaching unit (CTU) during 2005, and cared for by a clinical clerk, for documented functional assessment, cognitive assessment, recognition of medications that cause confusion, and early removal of indwelling urinary catheters. Performance of these outcomes was compared between clerks who had completed a mandatory 2-week geriatrics rotation immediately before the medical CTU rotation (n = 62) and those who completed geriatrics immediately after (n = 74). Patient outcomes were also measured and compared between groups.

RESULTS

Compared to clerks without prior geriatric exposure, clerks with geriatrics exposure were almost 3 times as likely to assess function of their older patients within two days of assuming care (27% vs. 12%, OR: 2.73, 95% CI: 1.12 to 6.66). There were no significant differences in the other clinical behaviors. Patients cared for by geriatrics-exposed clerks were less likely to die or be institutionalized (10% vs. 31%, OR: 0.24, 95% CI: 0.09 to 0.63), and they had shorter lengths of stay by an average of -7.14 days (95% CI: -12.2 to -2.07). Adjustment for baseline differences in age and cognitive impairment did not alter the results.

CONCLUSIONS

Clinical clerks who had completed a mandatory geriatrics rotation were more likely to document functional status upon assuming care of their older medical CTU patients, and there was also an association with better clinical outcomes. This highlights the value of including a geriatric medicine rotation as part of the core clerkship curriculum.

A prognostic model for 6-month mortality in elderly survivors of critical illness

BACKGROUND

Although 1.4 million elderly Americans survive hospitalization involving intensive care annually, many are at risk for early mortality following discharge. No models that predict the likelihood of death after discharge exist explicitly for this population. Therefore, we derived and externally validated a 6-month postdischarge mortality prediction model for elderly ICU survivors.

METHODS

We derived the model from medical record and claims data for 1,526 consecutive patients aged ≥ 65 years who had their first medical ICU admission in 2006 to 2009 at a tertiary-care hospital and survived to discharge (excluding those patients discharged to hospice). We then validated the model in 1,010 patients from a different tertiary-care hospital.

RESULTS

Six-month mortality was 27.3% and 30.2% in the derivation and validation cohorts, respectively. Independent predictors of mortality (in descending order of contribution to the model's predictive power) were a do-not-resuscitate order, older age, burden of comorbidity, admission from or discharge to a skilled-care facility, hospital length of stay, principal diagnoses of sepsis and hematologic malignancy, and male sex. For the derivation and external validation cohorts, the area under the receiver operating characteristic curve was 0.80 (SE, 0.01) and 0.71 (SE, 0.02), respectively, with good calibration for both (P = 0.31 and 0.43).

CONCLUSIONS

Clinical variables available at hospital discharge can help predict 6-month mortality for elderly ICU survivors. Variables that capture elements of frailty, disability, the burden of comorbidity, and patient preferences regarding resuscitation during the hospitalization contribute most to this model's predictive power. The model could aid providers in counseling elderly ICU survivors at high risk of death and their families.

Early recognition of risk factors for adverse outcomes during hospitalization among Medicare patients: a prospective cohort study

Background

There is a persistently high incidence of adverse events during hospitalization among Medicare beneficiaries. Attributes of vulnerability are prevalent, readily apparent, and therefore potentially useful for recognizing those at greatest risk for hospital adverse events who may benefit most from preventive measures. We sought to identify patient characteristics associated with adverse events that are present early in a hospital stay.

Methods

An interprofessional panel selected characteristics thought to confer risk of hospital adverse events and measurable within the setting of acute illness. A convenience sample of 214 Medicare beneficiaries admitted to a large, academic medical center were included in a quality improvement project to develop risk assessment protocols. The data were subsequently analyzed as a prospective cohort study to test the association of risk factors, assessed within 24 hours of hospital admission, with falls, hospital-acquired pressure ulcers (HAPU) and infections (HAI), adverse drug reactions (ADE) and 30-day readmissions.

Results

Mean age = 75(±13.4) years. Risk factors with highest prevalence included >4 active comorbidities (73.8%), polypharmacy (51.7%), and anemia (48.1%). One or more adverse hospital outcomes occurred in 46 patients (21.5%); 56 patients (26.2%) were readmitted within 30 days. Cluster analysis described three adverse outcomes: 30-day readmission, and two groups of in-hospital outcomes. Distinct regression models were identified: Weight loss (OR = 3.83; 95% CI = 1.46, 10.08) and potentially inappropriate medications (OR = 3.05; 95% CI = 1.19, 7.83) were associated with falls, HAPU, procedural complications, or transfer to intensive care; cognitive impairment (OR = 2.32; 95% CI = 1.24, 4.37), anemia (OR = 1.87; 95% CI = 1.00, 3.51) and weight loss (OR = 2.89; 95% CI = 1.38, 6.07) were associated with HAI, ADE, or length of stay >7 days; hyponatremia (OR = 3.49; 95% CI = 1.30, 9.35), prior hospitalization within 30 days (OR = 2.66; 95% CI = 1.31, 5.43) and functional impairment (OR = 2.05; 95% CI = 1.02, 4.13) were associated with 30-day readmission.

Conclusions

Patient characteristics recognizable within 24 hours of admission can be used to identify increased risk for adverse events and 30-day readmission.

Drug Burden Index and hospitalization among community-dwelling older people

BACKGROUND

Medications with anticholinergic and sedative effects carry significant risks in older people. Adverse events arising from the use of these medications may also lead to hospitalization and contribute to length of stay. The Drug Burden Index (DBI) is a tool that measures a person's total exposure to medications with anticholinergic and sedative properties, using the principles of dose response and maximal effect. Cumulative anticholinergic and sedative drug burden measured using the DBI has been associated with clinically important outcomes in older people. The association between the DBI and hospitalization still remains relatively unknown.

OBJECTIVE

The main aim of this study was to evaluate the relationship between DBI and hospitalization in a population-based sample of community-dwelling older Finns over a 1-year period.

METHODS

The health status and medication use of 339 community-dwelling ≥75-year-old Finns were assessed in 2004. Data on hospitalizations over the following year were obtained from the national discharge register. Two different measures were used to assess hospitalizations in the study sample: (i) the proportion of hospitalized participants; and (ii) the number of hospital days per person-year. Estimates for the number of hospital days per person-year and rate ratios (RRs) with 95% confidence intervals (CIs) were calculated using Poisson or negative binomial regression analysis.

RESULTS

A total of 127 participants (38%) were exposed to DBI medications; 27% had a low DBI (>0 to <1), and 11% had a high DBI (≥1). The number of hospital days per person-year was 7.9 (95% CI 7.6, 8.3) for the unexposed participants (DBI = 0) and 13.4 (95% CI 12.8, 14.1) for the exposed participants (DBI >1); the age, gender and co-morbidity adjusted RR of hospital days per person-year between the exposed and unexposed participants was 1.26 (95% CI 1.18, 1.35). Between the low and high DBI groups, the difference in the number of hospital days per person-year was insignificant (p = 0.42). In multivariate analyses, the number of regularly used medications (RR = 1.12 [95% CI 1.00, 1.26] per additional medication) and the measure of basic activities of daily living Barthel Index (RR = 0.94 [95% CI 0.88, 0.99] per increase) were independently associated with the use of hospital days.

CONCLUSION

Exposure to DBI medications was associated with a greater use of hospital days, but a cumulative dose-response relationship between DBI and hospitalization was not observed. The number of regularly used medications and functioning in the basic activities of daily living predicted hospital care utilization.

Risk of dementia in an elderly population of Parkinson's disease patients: a 15-year population-based study

BACKGROUND

The incidence of dementia in Parkinson's disease (PD) is not fully known, and previous studies have provided a wide range of rates owing to variations in diagnostic criteria and methodologies used. We estimated the risk of dementia in newly diagnosed cases of PD in a population-based cohort of subjects aged >65 years.

METHODS

We performed repetitive systematic screening of PD diagnosis, cognitive performances, and clinical dementia during 15 years (at year 0, 3, 5, 8, 10, and 15) in 3726 elderly subjects living at home in southwestern France (PAQUID). Two sets of diagnostic criteria for dementia in PD were considered: Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised criteria and Movement Disorders Society criteria.

RESULTS

Forty-four incident cases of PD occurred in the cohort; of these, 18 (41%) developed dementia during a mean follow-up of 6.8 ± 3.6 years. Incidence rate of dementia associated with PD was 74 per 1000 patient-years. The cumulative risk of dementia was approximately 25% and 50% after 5 and 10 years of follow-up, respectively. The relative risk for developing dementia in incident PD subjects compared with non-PD subjects was 2.47 (1.55-3.95). Equivalent estimations were obtained with Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised criteria or Movement Disorders Society criteria.

CONCLUSION

PD represents a high-risk stage for dementia in the general population.

Frailty in Older Adults Using Pre-hospital Care and the Emergency Department: A Narrative Review

BACKGROUND

Older adults use more health-care services per capita than younger age groups and the older adult population varies greatly in its needs. Evidence suggests that there is a critical distinction between relative frailty and fitness in older adults. Here, we review how frailty is described in the pre-hospital literature and in the broader emergency medicine literature.

METHODS

PubMed was used as the primary database, but was augmented by searches of CINAHL and EMBASE. Articles were included if they focused on patients 60 years and older and implemented a definition of frailty or risk screening tool in the Emergency Medical Services (EMS) or Emergency Department setting.

RESULTS

IN THE BROAD CLINICAL LITERATURE, THREE TYPES OF MEASURES CAN BE IDENTIFIED: frailty index measures, frailty scales, and a phenotypic definition. Each offers advantages and disadvantages for the EMS stakeholder. We identified no EMS literature on frailty conceptualization or management, although some risk measures from emergency medicine use terms that overlap with the frailty literature.

CONCLUSIONS

There is a paucity of research on frailty in the Emergency Medical Services literature. No research was identified that specifically addressed frailty conceptualization or management in EMS patients. There is a compelling need for further research in this area.

Physician and nurse acceptance of technicians to screen for geriatric syndromes in the emergency department

INTRODUCTION

The objective of this study was to evaluate emergency medicine physician and nurse acceptance of nonnurse, nonphysician screening for geriatric syndromes.

METHODS

This was a single-center emergency department (ED) survey of physicians and nurses after an 8-month project. Geriatric technicians were paid medical student research assistants evaluating consenting ED patients older than 65 years for cognitive dysfunction, fall risk, or functional decline. The primary objective of this anonymous survey was to evaluate ED nurse and physician perceptions about the geriatric screener feasibility and barriers to implementation. In addition, as a secondary objective, respondents reported ongoing geriatric screening efforts independent of the research screeners.

RESULTS

The survey was completed by 72% of physicians and 33% of nurses. Most nurses and physicians identified geriatric technicians as beneficial to patients without impeding ED throughput. Fewer than 25% of physicians routinely screen for any geriatric syndromes. Nurses evaluated for fall risk significantly more often than physicians, but no other significant differences were noted in ongoing screening efforts.

CONCLUSION

Dedicated geriatric technicians are perceived by nurses and physicians as beneficial to patients with the potential to improve patient safety and clinical outcomes. Most nurses and physicians are not currently screening for any geriatric syndromes.
