Recent Health Care Transitions and Emergency Department Use by Chronic Long Term Care Residents: A Population-Based Cohort Study

Development of the electronic consultation long-term care utilization and savings estimator tool to model the potential impact of electronic consultation for residents living in long-term care

Ageing populations have resulted in more patients living in long-term care or nursing homes, where they face challenges to accessing prompt specialist care exacerbated in many cases by physical or cognitive decline. Electronic consultation has demonstrated an ability to improve access to specialist care for vulnerable groups and offers a potential solution to this gap in care. To support electronic consultation's uptake among long-term care homes, we created the electronic consultation long-term care utilization and savings estimator, an Excel-based tool that estimates the number of off-site appointments that patients in a long-term care home could avoid through electronic consultation, along with the consequent time and cost savings. In this brief report, we discuss the electronic consultation long-term care utilization and savings estimator's creation and function, and provide a case study using long-term care data to demonstrate its potential impact. We anticipate the electronic consultation long-term care utilization and savings estimator will be a highly impactful tool and intend to test it in real-world conditions following the relaxation of COVID-19 restrictions.

Evaluating methods for risk prediction of Covid-19 mortality in nursing home residents before and after vaccine availability: a retrospective cohort study

BACKGROUND

SARS-CoV-2 vaccines are effective in reducing hospitalization, COVID-19 symptoms, and COVID-19 mortality for nursing home (NH) residents. We sought to compare the accuracy of various machine learning models, examine changes to model performance, and identify resident characteristics that have the strongest associations with 30-day COVID-19 mortality, before and after vaccine availability.

METHODS

We conducted a population-based retrospective cohort study analyzing data from all NH facilities across Ontario, Canada. We included all residents diagnosed with SARS-CoV-2 and living in NHs between March 2020 and July 2021. We employed five machine learning algorithms to predict COVID-19 mortality, including logistic regression, LASSO regression, classification and regression trees (CART), random forests, and gradient boosted trees. The discriminative performance of the models was evaluated using the area under the receiver operating characteristic curve (AUC) for each model using 10-fold cross-validation. Model calibration was determined through evaluation of calibration slopes. Variable importance was calculated by repeatedly and randomly permutating the values of each predictor in the dataset and re-evaluating the model's performance.

RESULTS

A total of 14,977 NH residents and 20 resident characteristics were included in the model. The cross-validated AUCs were similar across algorithms and ranged from 0.64 to 0.67. Gradient boosted trees and logistic regression had an AUC of 0.67 pre- and post-vaccine availability. CART had the lowest discrimination ability with an AUC of 0.64 pre-vaccine availability, and 0.65 post-vaccine availability. The most influential resident characteristics, irrespective of vaccine availability, included advanced age (≥ 75 years), health instability, functional and cognitive status, sex (male), and polypharmacy.

CONCLUSIONS

The predictive accuracy and discrimination exhibited by all five examined machine learning algorithms were similar. Both logistic regression and gradient boosted trees exhibit comparable performance and display slight superiority over other machine learning algorithms. We observed consistent model performance both before and after vaccine availability. The influence of resident characteristics on COVID-19 mortality remained consistent across time periods, suggesting that changes to pre-vaccination screening practices for high-risk individuals are effective in the post-vaccination era.

Unplanned Hospital Visits and Poor Oral Health With Undernutrition in Nursing Home Residents

OBJECTIVES

In 2021, the Japanese government began operating a long-term care (LTC) database called the Long-Term Care Information System for Evidence (LIFE). However, its utility has not been verified. Regarding unplanned hospital visits of nursing home residents, one of the challenges in LTC is that poor oral health with undernutrition could indicate high-risk residents. Therefore, this study examined the association between poor oral health with undernutrition assessed using the LIFE data and unplanned hospital visits of nursing home residents.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

The participants were 237 residents aged ≥65 years in 4 nursing homes in Japan. The analyses included 1041 LIFE data entries repeatedly measured for the participants every month and unplanned hospital visit data during the observation period.

METHODS

The participants' LIFE and unplanned hospital visit data were obtained from the nursing home providers. Poor oral health was defined using oral items included in the LIFE data and body mass index. Using the LIFE data, the association between poor oral health and unplanned hospital visits within 1 month after LIFE assessment entries was analyzed. The odds ratios (ORs) and 95% CIs were calculated using a generalized linear mixed model.

RESULTS

In total, 59 of 1041 LIFE data (5.7%) entries were unplanned hospital visits within 1 month after LIFE assessment. Among patient characteristics, significant differences were noted in dementia diagnosis [OR (95% CI): 2.66 (1.26-5.63)], although no significant differences were observed in other characteristics. Multivariate analysis using participant identification as a random effect confirmed that poor oral health was associated with unplanned hospital visits within 1 month [adjusted OR (95% CI): 2.63 (1.05-6.61)].

CONCLUSIONS AND IMPLICATIONS

Poor oral health assessed using the LIFE data could be used as an indicator to identify nursing home residents at high risk for unplanned hospital visits.

Examining the "Potentially Preventable Emergency Department Transfer" Indicator Among Nursing Home Residents

OBJECTIVE

To determine if nursing home (NH) resident characteristics associated with potentially preventable emergency department transfers (PPEDs) are similarly associated with non-potentially preventable emergency department transfers (non-PPEDs).

DESIGN

We conducted a population-level retrospective cohort study using linked administrative data reported using the Resident Assessment Instrument-Minimum Data Set Version 2.0 and the National Ambulatory Care Reporting System for emergency department transfers.

SETTING AND PARTICIPANTS

We assessed all NH residents transferred to the emergency department within 92 days after admission. The cohort included 56,433 NH resident admissions assessment of which 3498 NH residents experienced PPEDs, and 9331 residents experienced non-PPEDs.

METHODS

We assessed Ontario NH residents admission assessments collected between January 1, 2017, and December 31, 2018. We used cumulative incidence functions and Cox regression to compare resident characteristics between residents experiencing PPEDs and non-PPEDs. PPEDs were defined based on the International Classification of Diseases, 10th Revision.

RESULTS

Approximately 23% of residents experienced an emergency department transfer within 92 days of NH admission. The cumulative incidence of PPEDs was 6.3% and non-PPEDs was 16.8%. After adjusting for clinically relevant features, 14 of 18 resident admission characteristics were associated with both types of transfers. Resident admission characteristics associated with a greater risk of PPEDs solely were pneumonia [hazard ratio (HR) 1.48; CI 1.25-1.70] and oxygen therapy (HR 1.88; CI 1.69-2.10). Resident admission characteristics associated with a greater risk of non-PPEDs solely are experiencing a change in mood (HR 1.09; CI 1.01-1.18) and delirium (HR 1.08; CI 1.04-1.13).

CONCLUSIONS AND IMPLICATIONS

PPEDs were associated with a similar cluster of NH resident characteristics as those transferred for non-ambulatory reasons, suggesting that the clinical distinction between PPEDs vs non-PPEDs within the NH might be unclear. These findings highlight that the PPED indicator could be revised to improve specificity.

Recevoir un soutien aux capacités d’autosoins lors de la transition posthospitalisation en résidence pour aînés en perte d’autonomie : un besoin non comblé

INTRODUCTION

Elderly people who receive appropriate transitional care after hospitalization experience fewer complications.

CONTEXT

However, in Quebec, transitional care for the elderly is limited to case management and targets elderly people who are in need of resources. This often excludes those who remain in homes for the elderly.

OBJECTIVES

The objective of this study was to identify the unmet needs of elderly people during the posthospitalization transition to intermediate care facilities in Quebec, as well as the strategies they use on a daily basis to cope with these needs.

METHODS

A descriptive qualitative study was conducted as part of an intervention research process. Eleven elderly participants and health professionals were recruited (n=11).

RESULTS

The results presented suggest a need to support patients' capacity for self-care, unmet during the post-hospitalization transition to intermediate care facilities.

DISCUSSION

Supporting the self-care abilities of elderly people can help ensure their safety when living in homes for the elderly.

CONCLUSION

Supporting the capacity for self-care is an important component of transitional care after hospitalization, including for elderly people with disabilities.

Factors associated with increased Emergency Department transfer in older long-term care residents: a systematic review

The proportion of adults older than 65 years is rapidly increasing. Care home residents in this age group have disproportionate rates of transfer to the Emergency Department (ED) and around 40% of attendances might be avoidable. We did a systematic review to identify factors that predict ED transfer from care homes. Six electronic databases were searched. Observational studies that provided estimates of association between ED attendance and variables at a resident or care home level were included. 26 primary studies met the inclusion criteria. Seven common domains of factors assessed for association with ED transfer were identified and within these domains, male sex, age, presence of specific comorbidities, polypharmacy, rural location, and care home quality rating were associated with likelihood of ED transfer. The identification of these factors provides useful information for policy makers and researchers intending to either develop interventions to reduce hospitalisations or use adjusted rates of hospitalisation as a care home quality indicator.

Using meta-ethnography to understand the care transition experience of people with dementia and their caregivers

Older adults living with dementia are at risk for more complex health care transitions than individuals without this condition, non-impaired individuals. Poor quality care transitions have resulted in a growing body of qualitative empirical literature that to date has not been synthesized. We conducted a systematic literature review by applying a meta-ethnography approach to answer the following question: How do older adults with dementia and/or their caregivers experience and perceive healthcare transition: Screening resulted in a total of 18 studies that met inclusion criteria. Our analysis revealed the following three categories associated with the health care transition: (1) Feelings associated with the healthcare transition; (2) processes associated with the healthcare transition; and (3) evaluating the quality of care associated with the health care transition. Each category is represented by several themes that together illustrate an interconnected and layered experience. The health care transition, often triggered by caregivers reaching a "tipping point," is manifested by a variety of feelings, while simultaneously caregivers report managing abrupt transition plans and maintaining vigilance over care being provided to their family member. Future practice and research opportunities should be more inclusive of persons with dementia and should establish ways of better supporting caregivers through needs assessments, addressing feelings of grief, ongoing communication with the care team, and integrating more personalized knowledge at points of transition.

Nursing Home Resident Admission Characteristics and Potentially Preventable Emergency Department Transfers

OBJECTIVES

To determine which nursing home (NH) resident-level admission characteristics are associated with potentially preventable emergency department (PPED) transfers.

DESIGN

We conducted a population-level retrospective cohort study on NH resident data collected using the Resident Assessment Instrument-Minimum Data Set Version 2.0 and linked to the National Ambulatory Care Reporting System for ED transfers.

SETTING

We used all NH resident admission assessments from January 1, 2017, to December 31, 2018, in Ontario.

PARTICIPANTS

The cohort included the admission assessment of 56,433 NH residents.

METHODS

PPED transfers were defined based on the International Classification of Disease, Version 10 (Canadian) We used logistic regression with 10-fold cross-validation and computed average marginal effects to identify the association between resident characteristics at NH admission and PPED transfers within 92 days after admission.

RESULTS

Overall, 6.2% of residents had at least 1 PPED transfer within 92 days of NH admission. After adjustment, variables that had a prevalence of 10% or more that were associated with a 1% or more absolute increase in the risk of a PPED transfer included polypharmacy [of cohort (OC) 84.4%, risk difference (RD) 2.0%], congestive heart failure (OC 29.0%, RD 3.0%), and renal failure (OC 11.6%, RD 1.2%). Female sex (OC 63.2%, RD -1.3%), a do not hospitalize directive (OC 24.4%, RD -2.6%), change in mood (OC 66.9%, RD -1.2%), and Alzheimer's or dementia (OC 62.1%, RD -1.2%) were more than 10% prevalent and associated with a 1% or more absolute decrease in the risk of a PPED.

CONCLUSIONS AND IMPLICATIONS

Though many routinely collected resident characteristics were associated with a PPED transfer, the absence of sufficiently discriminating characteristics suggests that emergency department visits by NH residents are multifactorial and difficult to predict. Future studies should assess the clinical utility of risk factor identification to prevent transfers.

Social Services Involvement in Care Transitions and Admissions in Nursing Homes

Care transitions (CT) are critical junctures in the healthcare delivery process. Effective transitions reduce the need for subsequent transfers between healthcare settings, including nursing homes. Understanding social services (SS) involvement in these processes in nursing homes is important from a quality and holistic care perspective. Using logistic regression, this study examines structural and relational factors identified with higher involvement of SS in care transitions and admissions. SS directors from 924 nursing homes were evaluated in relation to SS involvement in care transitions and admissions processes. Results suggest the level of SS involvement in care transitions and admissions are associated with structural factors such as size of facility, geographical location, ratio of FTE's to beds, ownership status, and standalone SS departments, as well as relational factors, including perceptions and utilization of SS staff by facility leadership, coworkers, and family. Additionally, SS staff with higher levels of expertise and with social work degrees are less involved in admissions tasks.

Do Patients Retain their Family Physicians after Long-Term Care Entry? A Retrospective Cohort Study

OBJECTIVE

Older adults value and benefit from the long-standing relationship they have with their family physicians. This dynamic has not been researched in a long-term care (LTC, ie, nursing home) setting. We sought to determine the proportion of LTC residents who retain their community family physician within the first 180 days of LTC, and the resident, physician, and LTC home factors that may influence retention.

DESIGN

Population-based retrospective cohort study.

SETTING AND PARTICIPANTS

Individuals from Ontario, Canada, aged 60 years or older who were newly admitted to a LTC home between April 1, 2014 and March 31, 2017.

METHODS

Residents were indexed upon LTC admission, and their data was linked across ICES databases. Residents were matched to their rostered family physician, and physician retention was defined as having at least 1 visit by their matched physician within 0 to 90 days and 90 to 180 days of LTC admission.

RESULTS

Out of 50,089 LTC residents, 12.1% retained their family physicians post-LTC admission. Resident factors associated with reduced odds of retention included physical impairment [odds ratio OR (95% confidence interval, CI) = 0.59 (0.42‒0.83)], cognitive impairment [0.39 (0.33‒0.47)], and a dementia diagnosis [0.80 (0.74‒0.86)]. Physician factors associated with lower retention included a greater distance from the LTC home to the family physician's clinic [30+ kilometers 0.41 (0.35‒0.48)], having a physician who is female [0.90 (0.83‒0.98)], an international medical graduate [0.89 (0.81‒0.97)] or someone who practices in a capitation-based Family Health Organization [0.86 (0.78‒0.95)]. Factors associated with greater odds of retention were residing in a rural LTC home [2.23 (1.78‒2.79)], having a rural family physician [1.70 (1.52‒1.90)], or a family physician who has billed LTC fee codes in the past year [2.64 (2.45‒2.85)].

CONCLUSIONS AND IMPLICATIONS

Few LTC residents retained their family physician post-LTC admission, underscoring this healthcare transition as a breakdown point in relational continuity. Factors that influenced retention included resident health, LTC home geography, and family physician demographics and practice patterns.

Measuring multimorbidity series-an overlooked complexity comparison of self-report vs. administrative data in community-living adults: paper 2. Prevalence estimates depend on the data source

OBJECTIVE

The objective of the study was to compare multimorbidity prevalence using self-reported and administrative data and identify factors associated with agreement between data sources.

STUDY DESIGN AND SETTING

Self-reported cross-sectional data from four Canadian Community Health Survey waves were linked to administrative data in Ontario, Canada. Multimorbidity prevalence was examined using two definitions, 2+ and 3+ chronic conditions (CCs). Agreement between data sources was assessed using Kappa and Phi statistics. Logistic regression was used to estimate associations between agreement and sociodemographic, health behavior, and health status variables for each multimorbidity definition.

RESULTS

Regardless of multimorbidity definition, prevalence was higher using administrative data (2+ CCs: 55.5% vs. 47.1%; 3+ CCs: 30.0% vs. 24.2%). Agreement between data sources was moderate (2+ CCs K = 0.482; 3+ CCs K = 0.442), and while associated with sociodemographic, health behavior, and health status factors, the magnitude and sometimes direction of association differed by multimorbidity definition.

CONCLUSION

A better understanding is needed of what factors influence individuals' reporting of CCs and how they align with what is in administrative data as policy makers need a solid evidence base on which to make decisions for health planning. Our results suggest that data sources may need to be triangulated to provide accurate estimates of multimorbidity for health services planning and policy.

Influence of Psychotropic Medications on Readmission Rates of Patients Receiving a Pharmacist Discharge Medication Reconciliation

BACKGROUND

Current literature suggests that patients with psychiatric disorders are at an increased risk for inpatient readmission. This study evaluated the impact of pharmacist-driven discharge medication reconcilliation (DMR) on readmission rates of patients discharged with one or more psychotropic medications.

METHODS

This study was a retrospective review of patients receiving a pharmacist-driven DMR. The primary outcome was to compare the prevalence of 30-day readmission rates among patients who had a pharmacist DMR between patients who had at least one psychotropic medication upon discharge versus those without psychotropic medications. Secondary objectives were to (1) compare the number of medication discrepancies and pharmacist interventions prior to discharge and (2) compare prevalence of medical comorbidities between patients who had at least one psychotropic medication upon discharge versus those without psychotropic medications.

RESULTS

A total of 151 subjects were included who had a DMR and either at least one psychotropic medication at discharge (n = 69) or no psychotropic medications at discharge (n = 82). The 30-day readmission rates were similar between both groups (P = .609). The mean number of discrepancies (P < .001) and number of pharmacist interventions (P = .005) were significantly greater in patients who had at least one psychotropic medication upon discharge compared to those without psychotropic medication.

CONCLUSIONS

The prevalence of 30-day readmissions was similar between the two groups; however, patients discharged with at least one psychotropic medication had a greater number of discrepancies requiring significantly more discharge interventions during a pharmacist DMR.

Does older adults' use of social care influence their healthcare utilisation? A systematic review of international evidence

Improving our understanding of the complex relationship between health and social care utilisation is vital as populations age. This systematic review aimed to synthesise evidence on the relationship between older adults' use of social care and their healthcare utilisation. Ten databases were searched for international literature on social care (exposure), healthcare use (outcome) and older adults (population). Searches were carried out in October 2016, and updated May 2018. Studies were eligible if they were published after 2000 in a high income country, examined the relationship between use of social care and healthcare utilisation by older adults (aged ≥60 years), and controlled for an indicator of need. Study quality and bias were rated using the National Institute of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Study data were extracted and a narrative synthesis was conducted. Data were not suitable for quantitative synthesis. Thirteen studies were identified from 12,065 citations. Overall, the quality and volume of evidence was low. There was limited evidence to suggest that longer lengths of stay in care homes were associated with a lower risk of inpatient admissions. Residents of care homes with onsite nursing had fewer than expected admissions to hospital, compared to people in care homes without nursing, and adjusting for need. Evidence for other healthcare use outcomes was even more limited and heterogeneous, with notable gaps in primary care. We conclude that older adults' use of care homes may moderate inpatient admissions. In particular, the presence of registered nurses in care homes may reduce the need to transfer residents to hospital. However, further evidence is needed to add weight to this conclusion. Future research should build on this evidence and address gaps regarding the influence of community based social care on older adults' healthcare use. A greater focus on primary care outcomes is imperative.

Sex-Specific Differences in End-of-Life Burdensome Interventions and Antibiotic Therapy in Nursing Home Residents With Advanced Dementia

Importance

Nursing home residents with advanced dementia have limited life expectancies yet are commonly subjected to burdensome interventions at the very end of life. Whether sex-specific differences in the receipt of these interventions exist and what levels of physical restraints and antibiotics are used in this terminal setting are unknown.

Objective

To evaluate the population-based frequency, factors, and sex differences in burdensome interventions and antibiotic therapy among nursing home residents with advanced dementia.

Design, Setting, and Participants

This population-based cohort study from Ontario, Canada, used linked administrative databases held at ICES, including the Continuing Care Resident Reporting System Long-Term Care database, which contains data from the Resident Assessment Instrument Minimum Data Set, version 2.0. Nursing home residents (n = 27 243) with advanced dementia who died between June 1, 2010, and March 31, 2015, at 66 years or older were included in the analysis. Initial statistical analysis was completed in May 2017, and analytical revisions were conducted from November 2018 to January 2019.

Exposure

Sex of the nursing home resident.

Main Outcomes and Measures

Burdensome interventions (transitions of care, invasive procedures, and physical restraints) and antibiotic therapy in the last 30 days of life.

Results

The final cohort included 27 243 nursing home residents with advanced dementia (19 363 [71.1%] women) who died between June 1, 2010, and March 31, 2015, at the median (interquartile range) age of 88 (83-92) years. In the last 30 days of life, burdensome interventions were common, especially among men: 5940 (21.8%) residents were hospitalized (3661 women [18.9%] vs 2279 men [28.9%]; P < .001), 2433 (8.9%) had an emergency department visit (1579 women [8.2%] vs 854 men [10.8%]; P < .001), and 3701 (13.6%) died in an acute care facility (2276 women [11.8%] vs 1425 men [18.1%]; P < .001). Invasive procedures were also common; 2673 residents (9.8%) were attended for life-threatening critical care (1672 women [8.6%] vs 1001 men [12.7%]; P < .001), and 210 (0.8%) received mechanical ventilation (113 women [0.6%] vs 97 men [1.2%]; P < .001). Among the 9844 residents (36.1%) who had a Resident Assessment Instrument Minimum Data Set, version 2.0, completed in the last 30 days of life, 2842 (28.9%) were physically restrained (2002 women [28.3%] vs 840 men [30.4%]; P = .005). More than one-third (9873 [36.2%]) of all residents received an antibiotic (6599 women [34.1%] vs 3264 men [41.4%]; P < .001). In multivariable models, men were more likely to have a transition of care (adjusted odds ratio, 1.41; 95% CI, 1.33-1.49; P < .001) and receive antibiotics (adjusted odds ratio, 1.33; 95% CI, 1.26-1.41; P < .001). Only 3309 residents (12.1%; 2382 women [12.3%] vs 927 men [11.8%]) saw a palliative care physician in the year before death, but those who did experienced greater than 50% lower odds of an end-of-life transition of care (adjusted odds ratio, 0.48; 95% CI, 0.43-0.54); P < .001) and greater than 25% lower odds of receiving antibiotics (adjusted odds ratio, 0.74; 95% CI, 0.68-0.81; P < .001).

Conclusions and Relevance

In this study, many nursing home residents with advanced dementia, especially men, received burdensome interventions and antibiotics in their final days of life. These findings appear to emphasize the need for sex-specific analysis in dementia research as well as the expansion of palliative care and end-of-life antimicrobial stewardship in nursing homes.

Insights on multimorbidity and associated health service use and costs from three population-based studies of older adults in Ontario with diabetes, dementia and stroke

Background

Most studies that examine comorbidity and its impact on health service utilization focus on a single index-condition and are published in disease-specific journals, which limit opportunities to identify patterns across conditions/disciplines. These comparisons are further complicated by the impact of using different study designs, multimorbidity definitions and data sources. The aim of this paper is to share insights on multimorbidity and associated health services use and costs by reflecting on the common patterns across 3 parallel studies in distinct disease cohorts (diabetes, dementia, and stroke) that used the same study design and were conducted in the same health jurisdiction over the same time period.

Methods

We present findings that lend to broader Insights regarding multimorbidity based on the relationship between comorbidity and health service use and costs seen across three distinct disease cohorts. These cohorts were originally created using multiple linked administrative databases to identify community-dwelling residents of Ontario, Canada with one of diabetes, dementia, or stroke in 2008 and each was followed for health service use and associated costs.

Results

We identified 376,434 indviduals wtih diabetes, 95,399 wtih dementia, and 29,671 with stroke. Four broad insights were identified from considering the similarity in comorbidity, utilization and cost patterns across the three cohorts: 1) the most prevalent comorbidity types were hypertension and arthritis, which accounted for over 75% of comorbidity in each cohort; 2) overall utilization increased consistently with the number of comorbidities, with the vast majority of services attributed to comorbidity rather than the index conditions; 3) the biggest driver of costs for those with lower levels of comorbidity was community-based care, e.g., home care, GP visits, but at higher levels of comorbidity the driver was acute care services; 4) service-specific comorbidity and age patterns were consistent across the three cohorts.

Conclusions

Despite the differences in population demographics and prevalence of the three index conditions, there are common patterns with respect to comorbidity, utilization, and costs. These common patterns may illustrate underlying needs of people with multimorbidity that are often obscured in literature that is still single disease-focused.

London Transfer Project: improving handover documentation from long-term care homes to hospital emergency departments

About one-quarter of all long-term care (LTC) residents are transferred to an emergency department (ED) every 6 months in Ontario, Canada. When residents are unable to describe their health issues, ED staff rely on LTC transfer reports to make informed decisions. However, transfer information gaps are common, and may contribute to unnecessary tests, unwanted treatments and longer ED length of stay. London Health Sciences Centre, an academic hospital system in London, Ontario, partnered with 10 LTC homes to improve emergency reporting of their residents' reason for transfer and baseline cognition. After conducting a root cause analysis, 7 of 10 homes implemented a standard minimum set of currently available transfer forms, including a computer-generated summary of resident’s most recent interRAI functional assessment. Results were analysed using statistical process control charts and data were posted on a public website (LondonTransferProject.com). The documentation rate of ‘reason for transfer’ improved from 61% to 84%, and ‘baseline cognitive status’ improved from 4% to 56% across all 10 homes. These results suggest that transfer communication can be improved by codesigning and implementing solutions with ED and LTC staff, which build upon current reporting practices shared across multiple LTC organisations.

Nursing home residents at the Emergency Department: a 6-year retrospective analysis in a Swiss academic hospital

The increasing number of elderly persons produces an increase in emergency department (ED) visits by these patients, including nursing home (NH) residents. This trend implies a major challenge for the ED. This study sought to investigate ED visits by NH residents in an academic hospital. A retrospective monocentric analysis of all ED visits by NH residents between 2005 and 2010 in a Swiss urban academic hospital. All NH residents aged 65 years and over were included. Socio-demographic data, mode of transfer to ED, triage severity rating, main reason for visit, ED and hospital length of stay, discharge dispositions, readmission at 30 and 90 day were collected. Annual ED visits by NH residents increased by 50 % (from 465 to 698) over the study period, accounting for 1.5 to 1.9 % of all ED visits from 2005 to 2010, respectively. Over the period, yearly rates of ED visits increased steadily from 18.8 to 27.5 per 100 NH residents. Main reasons for ED visits were trauma, respiratory, cardiovascular, digestive, and neurological problems. 52 % were for urgent situations. Less than 2 % of NH residents died during their ED stay and 60 % were admitted to hospital wards. ED use by NH residents disproportionately increased over the period, likely reflecting changes in residents and caregivers' expectations, NH staff care delivery, as well as possible correction of prior ED underuse. These results highlight the need to improve ED process of care for these patients and to identify interventions to prevent potentially unnecessary ED transfers.

Comorbidity and its relationship with health service use and cost in community-living older adults with diabetes: A population-based study in Ontario, Canada

AIMS

This study describes the comorbid conditions in Canadian, community-dwelling older adults with diabetes and the association between the number of comorbidities and health service use and costs.

METHODS

This retrospective cohort study used multiple linked administrative data to determine 5-year health service utilization in a population-based cohort of community-living individuals aged 66 and over with a diabetes diagnosis as of April 1, 2008 (baseline). Utilization included physician visits, emergency department visits, hospitalizations, and home care services.

RESULTS

There were 376,421 cohort members at baseline, almost all (95%) of which had at least one comorbidity and half (46%) had 3 or more. The most common comorbidities were hypertension (83%) and arthritis (61%). Service use and associated costs consistently increased as the number of comorbidities increased across all services and follow-up years. Conditions generally regarded as nondiabetes-related were the main driver of service use. Over time, use of most services declined for people with the highest level of comorbidity (3+). Hospitalizations and emergency department visits represented the largest share of costs for those with the highest level of comorbidity (3+), whereas physician visits were the main costs for those with fewer comorbidities.

CONCLUSIONS

Comorbidities in community-living older adults with diabetes are common and associated with a high level of health service use and costs. Accordingly, it is important to use a multiple chronic conditions (not single-disease) framework to develop coordinated, comprehensive and patient-centred programs for older adults with diabetes so that all their needs are incorporated into care planning.

Patterns of health service use in community living older adults with dementia and comorbid conditions: a population-based retrospective cohort study in Ontario, Canada

Background

Patients with dementia have increased healthcare utilization and often have comorbid chronic conditions. It is not clear if the increase in utilization is driven by dementia, the comorbidities or both. The objective of this study was to describe the number and types of comorbid conditions in a population-based cohort of older adults with dementia and how the level of comorbidity impacts dementia-related and non-dementia-related health service utilization.

Methods

This study is a retrospective cohort study using multiple linked administrative databases to examine health service utilization and costs of 100,630 community-living older adults living with pre-existing dementia in Ontario, Canada. Comorbid conditions and health service utilization were measured using administrative data (physician visits, emergency department visits, hospitalizations, and homecare contacts).

Results

Nearly all, 96.3 %, had at least one comorbid condition, while 18.4 % had five or more comorbid conditions. The most common comorbid conditions were hypertension (77.8 %), and arthritis (66.2 %). All types of utilization increased consistently with the number of comorbid conditions. The average number of dementia-related services tended to be similar across all levels of comorbidity while the average number of non-dementia related visits tended to increase with the level of comorbidity.

Conclusions

Comorbidities in community-living older adults with dementia are common and account for a substantial proportion of health service use and costs in this population. Our results suggest that comprehensive programs that take a holistic view to identify the needs of patients in the context of other comorbidities are required for persons with dementia living in the community.

Patterns of Emergency Department Use Among Long-Stay Nursing Home Residents With Differing Levels of Dementia Severity

OBJECTIVES

To describe emergency department (ED) utilization among long-stay nursing home residents with different levels of dementia severity.

DESIGN

Retrospective cohort study.

SETTING

Public Health System.

PARTICIPANTS

A total of 4491 older adults (age 65 years and older) who were long-stay nursing home residents.

MEASUREMENTS

Patient demographics, dementia severity, comorbidities, ED visits, ED disposition decisions, and discharge diagnoses.

RESULTS

Forty-seven percent of all long-stay nursing home residents experienced at least 1 transfer to the ED over the course of a year. At their first ED transfer, 36.4% of the participants were admitted to the hospital, whereas 63.1% of those who visited the ED were not. The median time to first ED visit for the participants with advanced stage dementia was 258 days, whereas it was 250 days for the participants with early to moderate stage dementia and 202 days for the participants with no dementia (P = .0034). Multivariate proportional hazard modeling showed that age, race, number of comorbidities, number of hospitalizations in the year prior, and do not resuscitate status all significantly influenced participants' time to first ED visit (P < .05 for all). After accounting for these effects, dementia severity (P = .66), years in nursing home before qualification (P = .46), and gender (P = .36) lost their significance.

CONCLUSIONS

This study confirms high rates of transfer of long-stay nursing home residents, with nearly one-half of the participants experiencing at least 1 ED visit over the course of a year. Although dementia severity is not a predictor of time to ED use in our analyses, other factors that influence ED use are readily identifiable. Nursing home providers should be aware of these factors when developing strategies that meet patient care goals and avoid transfer from the nursing home to the ED.

Unintentional Discontinuation of Chronic Medications for Seniors in Nursing Homes: Evaluation of a National Medication Reconciliation Accreditation Requirement Using a Population-Based Cohort Study

Transitions of care leave patients vulnerable to the unintentional discontinuation of medications with proven efficacy for treating chronic diseases. Older adults residing in nursing homes may be especially susceptible to this preventable adverse event. The effect of large-scale policy changes on improving this practice is unknown.The objective of this study was to analyze the effect of a national medication reconciliation accreditation requirement for nursing homes on rates of unintentional medication discontinuation after hospital discharge.It was a population-based retrospective cohort study that used linked administrative records between 2003 and 2012 of all hospitalizations in Ontario, Canada. We identified nursing home residents aged ≥66 years who had continuous use of ≥1 of the 3 selected medications for chronic disease: levothyroxine, HMG-CoA reductase inhibitors (statins), and proton pump inhibitors (PPIs).In 2008 medication reconciliation became a required practice for accreditation of Canadian nursing homes.The main outcome measures included the proportion of patients who restarted the medication of interest after hospital discharge at 7 days. We also performed a time series analysis to examine the impact of the accreditation requirement on rates of unintentional medication discontinuation.The study included 113,088 adults aged ≥66 years who were nursing home residents, had an acute hospitalization, and were discharged alive to the same nursing home. Overall rates of discontinuation at 7-days after hospital discharge were highest in 2003-2004 for all nursing homes: 23.9% for thyroxine, 26.4% for statins, and 23.9% for PPIs. In most of the cases, these overall rates decreased annually and were lowest in 2011-2012: 4.0% for thyroxine, 10.6% for statins, and 8.3% for PPIs. The time series analysis found that nursing home accreditation did not significantly lower medication discontinuation rates for any of the 3 drug groups.From 2003 to 2012, there were marked improvements in rates of unintentional medication discontinuation among hospitalized older adults who were admitted from and discharged to nursing homes. This change was not directly associated with the new medication reconciliation accreditation requirement, but the overall improvements observed may have been reflective of multiple processes and not 1 individual intervention.

Nurse-led ED support for residential aged care facility staff: an evaluation study

OBJECTIVES

To evaluate the impact of a nurse-led telephone support service to Residential Aged Care Facilities (RACFs) on a range of measures relating to the transfer of acutely unwell residents to the Emergency Department (ED) of a large tertiary referral hospital in New South Wales, Australia over a 9 month period.

METHODS

A pre- and post-intervention design determined the impact of the telephone service, associated clinical guidelines and education. Data from 4 intervention RACFs using the nurse-led telephone service were compared with 8 control RACFs. Data included the older patient's triage category, presenting problem(s), transfer rates from RACFs, ED admissions, and overall hospital length of stay. Interviews and focus groups with staff from RACFs and EDs were conducted to ascertain their experiences.

RESULTS

Reduced presentations of older people to the ED from the 4 pilot RACFs occurred. High levels of satisfaction among staff in RACFs were reported.

A systematic review of outcomes following emergency transfer to hospital for residents of aged care facilities

BACKGROUND

residential aged care facility (RACF) resident numbers are increasing. Residents are frequently frail with substantial co-morbidity, functional and cognitive impairment with high susceptibility to acute illness. Despite living in facilities staffed by health professionals, a considerable proportion of residents are transferred to hospital for management of acute deteriorations in health. This model of emergency care may have unintended consequences for patients and the healthcare system. This review describes available evidence about the consequences of transfers from RACF to hospital.

METHODS

a comprehensive search of the peer-reviewed literature using four electronic databases. Inclusion criteria were participants lived in nursing homes, care homes or long-term care, aged at least 65 years, and studies reported outcomes of acute ED transfer or hospital admission. Findings were synthesized and key factors identified.

RESULTS

residents of RACF frequently presented severely unwell with multi-system disease. In-hospital complications included pressure ulcers and delirium, in 19 and 38% of residents, respectively; and up to 80% experienced potentially invasive interventions. Despite specialist emergency care, mortality was high with up to 34% dying in hospital. Furthermore, there was extensive use of healthcare resources with large proportions of residents undergoing emergency ambulance transport (up to 95%), and inpatient admission (up to 81%).

CONCLUSIONS

acute emergency department (ED) transfer is a considerable burden for residents of RACF. From available evidence, it is not clear if benefits of in-hospital emergency care outweigh potential adverse complications of transfer. Future research is needed to better understand patient-centred outcomes of transfer and to explore alternative models of emergency healthcare.

Emergency ambulance service involvement with residential care homes in the support of older people with dementia: an observational study

BACKGROUND

Older people resident in care homes have a limited life expectancy and approximately two-thirds have limited mental capacity. Despite initiatives to reduce unplanned hospital admissions for this population, little is known about the involvement of emergency services in supporting residents in these settings.

METHODS

This paper reports on a longitudinal study that tracked the involvement of emergency ambulance personnel in the support of older people with dementia, resident in care homes with no on-site nursing providing personal care only. 133 residents with dementia across 6 care homes in the East of England were tracked for a year. The paper examines the frequency and reasons for emergency ambulance call-outs, outcomes and factors associated with emergency ambulance service use.

RESULTS

56% of residents used ambulance services. Less than half (43%) of all call-outs resulted in an unscheduled admission to hospital. In addition to trauma following a following a fall in the home, results suggest that at least a reasonable proportion of ambulance contacts are for ambulatory care sensitive conditions. An emergency ambulance is not likely to be called for older rather than younger residents or for women more than men. Length of residence does not influence use of emergency ambulance services among older people with dementia. Contact with primary care services and admission route into the care home were both significantly associated with emergency ambulance service use. The odds of using emergency ambulance services for residents admitted from a relative's home were 90% lower than the odds of using emergency ambulance services for residents admitted from their own home.

CONCLUSIONS

Emergency service involvement with this vulnerable population merits further examination. Future research on emergency ambulance service use by older people with dementia in care homes, should account for important contextual factors, namely, presence or absence of on-site nursing, GP involvement, and access to residents' family, alongside resident health characteristics.

The Department of Veterans Affairs' (VA) implementation of the Virtual Lifetime Electronic Record (VLER): findings and lessons learned from Health Information Exchange at 12 sites

PURPOSE

We describe the Department of Veterans Affairs' (VA) Virtual Lifetime Health Electronic Record (VLER) pilot phase in 12 communities to exchange health information with private sector health care organizations and the Department of Defense (DoD), key findings, lessons, and implications for advancing Health Information Exchanges (HIE), nationally.

METHODS

A mixed methods approach was used to monitor and evaluate the status of VLER Health Exchange pilot phase implementation from December 2009 through October 2012. Selected accomplishments, contributions, challenges, and early lessons that are relevant to the growth of nationwide HIE are discussed.

RESULTS

Veteran patient and provider acceptance, trust, and perceived value of VLER Health Exchange are found to be high, and usage by providers is steadily growing. Challenges and opportunities to improve provider use are identified, such as better data quality and integration with workflow. Key findings and lessons for advancing HIE are identified.

CONCLUSIONS

VLER Health Exchange has made great strides in advancing HIE nationally by addressing important technical and policy issues that have impeded scalability, and by increasing trust and confidence in the value and accuracy of HIE among users. VLER Health Exchange has advanced HIE interoperability standards and patient consent policies nationally. Policy, programmatic, technology, and health Information Technology (IT) standards implications to advance HIE for improved delivery and coordination of health care are discussed. The pilot phase success led to VA-wide deployment of this data sharing capability in 2013.

The Older Persons' Transitions in Care (OPTIC) study: pilot testing of the transition tracking tool

Background

OPTIC is a mixed method Partnership for Health System Improvement (http://www.cihr-irsc.gc.ca/e/34348.html) study focused on improving care for nursing home (NH) residents who are transferred to and from emergency departments (EDs) via emergency medical services (EMS). In the pilot study we tested feasibility of concurrently collecting individual resident data during transitions across settings using the Transition Tracking Tool (T3).

Methods

The pilot study tracked 54 residents transferred from NHs to one of two EDs in two western Canadian provinces over a three month period. The T3 is an electronic data collection tool developed for this study to record data relevant to describing and determining success of transitions in care. It comprises 800+ data elements including resident characteristics, reasons and precipitating factors for transfer, advance directives, family involvement, healthcare services provided, disposition decisions, and dates/times and timing.

Results

Residents were elderly (mean age = 87.1 years) and the majority were female (61.8%). Feasibility of collecting data from multiple sources across two research sites was established. We identified resources and requirements to access and retrieve specific data elements in various settings to manage data collection processes and allocate research staff resources. We present preliminary data from NH, EMS, and ED settings.

Conclusions

While most research in this area has focused on a unidirectional process of patient progression from one care setting to another, this study established feasibility of collecting detailed data from beginning to end of a transition across multiple settings and in multiple directions.

Within-hospital readmission: an indicator of readmission after discharge from psychiatric hospitalization

OBJECTIVE

Readmission after psychiatric hospitalization is widely used as a quality of care indicator by government funding agencies, policy-makers, and hospitals deciding on clinical priorities. Readmission rates are calculated accurately to allow these varied groups to correctly translate the knowledge into appropriate, tangible outcomes. We aimed to assess how well hospital readmission rates, calculated using only readmissions to the discharging institution, can approximate actual readmission rates.

METHOD

We used administrative data sources to identify patients with a mental health discharge in the province of Ontario (2008-2011). We identified mental health readmissions within 30 and 90 days of discharge occurring to the hospital from which the patient was discharged (within-hospital readmissions), and compared readmission rates using only within-hospital admissions with actual readmission rates.

RESULTS

The percentage of readmissions occurring to the discharging institution ranged from 39% to 89% (median 73%) and from 37% to 86% (median 70%) for 30- and 90-day readmissions, respectively. Using only within-hospital readmissions to rank hospitals by their readmission rates, only 56% of hospitals for 30-day readmissions and 50% for 90-day readmissions were ranked in the same quartile as when actual readmission rates were used.

CONCLUSIONS

These findings highlight the importance of measuring psychiatric readmissions at the system level, particularly for hospitals with lower discharge volumes. As well, the high likelihood that multiple hospitals are involved in the hospital-based care of people who require readmission requires consideration at clinical and policy levels.
