Reliability of the interRAI suite of assessment instruments: a 12-country study of an integrated health information system

Managing clinical uncertainty in older people towards the end of life: a systematic review of person-centred tools

Background

Older people with multi-morbidities commonly experience an uncertain illness trajectory. Clinical uncertainty is challenging to manage, with risk of poor outcomes. Person-centred care is essential to align care and treatment with patient priorities and wishes. Use of evidence-based tools may support person-centred management of clinical uncertainty. We aimed to develop a logic model of person-centred evidence-based tools to manage clinical uncertainty in older people.

Methods

A systematic mixed-methods review with a results-based convergent synthesis design: a process-based iterative logic model was used, starting with a conceptual framework of clinical uncertainty in older people towards the end of life. This underpinned the methods. Medline, PsycINFO, CINAHL and ASSIA were searched from 2000 to December 2019, using a combination of terms: “uncertainty” AND “palliative care” AND “assessment” OR “care planning”. Studies were included if they developed or evaluated a person-centred tool to manage clinical uncertainty in people aged ≥65 years approaching the end of life and quality appraised using QualSyst. Quantitative and qualitative data were narratively synthesised and thematically analysed respectively and integrated into the logic model.

Results

Of the 17,095 articles identified, 44 were included, involving 63 tools. There was strong evidence that tools used in clinical care could improve identification of patient priorities and needs (n = 14 studies); that tools support partnership working between patients and practitioners (n = 8) and that tools support integrated care within and across teams and with patients and families (n = 14), improving patient outcomes such as quality of death and dying and satisfaction with care. Communication of clinical uncertainty to patients and families had the least evidence and is challenging to do well.

Conclusion

The identified logic model moves current knowledge from conceptualising clinical uncertainty to applying evidence-based tools to optimise person-centred management and improve patient outcomes. Key causal pathways are identification of individual priorities and needs, individual care and treatment and integrated care. Communication of clinical uncertainty to patients is challenging and requires training and skill and the use of tools to support practice.

Prognosis does not change the landscape: palliative home care clients experience high rates of pain and nausea, regardless of prognosis

BACKGROUND

Most individuals who typically receive palliative care (PC) tend to have cancer and a relatively short prognosis (< 6 months). People with other life-limiting illnesses can also benefit from a palliative care approach. However, little is known about those who receive palliative home care in Ontario, Canada's largest province. To address this gap, the goal of this project was to understand the needs, symptoms and potential differences between those with a shorter (< 6 months) and longer prognosis (6+ months) for individuals receiving PC in the community.

METHODS

A cross-sectional analysis was conducted using interRAI Palliative Care (interRAI PC) assessment data collected between 2011 and 2018. Individuals with a shorter prognosis (< 6 months; n = 48,019 or 64.1%) were compared to those with a longer prognosis (6+ months; n = 26,945) across several clinical symptoms. The standardized difference (stdiff), between proportions, was calculated to identify statistically meaningful differences between those with a shorter and longer prognosis. Values of the stdiff of 0.2 or higher (absolute value) indicated a statistically significant difference.

RESULTS

Overall, cancer was the most prevalent diagnosis (83.2%). Those with a shorter prognosis were significantly more likely to experience fatigue (75.3% vs. 59.5%; stdiff = 0.34) and shortness of breath at rest (22.1% vs. 13.4%; stdiff = 0.23). However, the two groups were similar in terms of severe pain (73.5% vs. 66.5%; stdiff = - 0.15), depressive symptoms (13.2% vs. 10.7%; stdiff = 0.08) and nausea (35.7% vs. 29.4%; stdiff = 0.13).

CONCLUSIONS

These results highlight the importance of earlier identification of individuals who could benefit from a palliative approach to their care as individuals with a longer prognosis also experience high rates of symptoms such as pain and nausea. Providing PC earlier in the illness trajectory has the potential to improve an individual's overall quality of life throughout the duration of their illness.

Identifying Unexpected Deaths in Long-Term Care Homes

OBJECTIVES

Predicting unexpected deaths among long-term care (LTC) residents can provide valuable information to clinicians and policy makers. We study multiple methods to predict unexpected death, adjusting for individual and home-level factors, and to use as a step to compare mortality differences at the facility level in the future work.

DESIGN

We conducted a retrospective cohort study using Resident Assessment Instrument Minimum Data Set assessment data for all LTC residents in Ontario, Canada, from April 2017 to March 2018.

SETTING AND PARTICIPANTS

All residents in Ontario long-term homes. We used data routinely collected as part of administrative reporting by health care providers to the funder: Ontario Ministry of Health and Long-Term Care. This project is a component of routine policy development to ensure safety of the LTC system residents.

METHODS

Logistic regression (LR), mixed-effect LR (mixLR), and a machine learning algorithm (XGBoost) were used to predict individual mortality over 5 to 95 days after the last available RAI assessment.

RESULTS

We identified 22,419 deaths in the cohort of 106,366 cases (mean age: 83.1 years; female: 67.7%; dementia: 68.8%; functional decline: 16.6%). XGBoost had superior calibration and discrimination (C-statistic 0.837) over both mixLR (0.819) and LR (0.813). The models had high correlation in predicting death (LR-mixLR: 0.979, LR-XGBoost: 0.885, mixLR-XGBoost: 0.882). The inter-rater reliability between the models LR-mixLR and LR-XGBoost was 0.56 and 0.84, respectively. Using results in which all 3 models predicted probability of actual death of a resident at <5% yielded 210 unexpected deaths or 0.9% of the observed deaths.

CONCLUSIONS AND IMPLICATIONS

XGBoost outperformed other models, but the combination of 3 models provides a method to detect facilities with potentially higher rates of unexpected deaths while minimizing the possibility of false positives and could be useful for ongoing surveillance and quality assurance at the facility, regional, and national levels.

Predicting unplanned hospital visits in older home care recipients: a cross-country external validation study

Background

Accurate identification of older persons at risk of unplanned hospital visits can facilitate preventive interventions. Several risk scores have been developed to identify older adults at risk of unplanned hospital visits. It is unclear whether risk scores developed in one country, perform as well in another. This study validates seven risk scores to predict unplanned hospital admissions and emergency department (ED) visits in older home care recipients from six countries.

Methods

We used the IBenC sample (n = 2446), a cohort of older home care recipients from six countries (Belgium, Finland, Germany, Iceland, Italy and The Netherlands) to validate four specific risk scores (DIVERT, CARS, EARLI and previous acute admissions) and three frailty indicators (CHESS, Fried Frailty Criteria and Frailty Index). Outcome measures were unplanned hospital admissions, ED visits or any unplanned hospital visits after 6 months. Missing data were handled by multiple imputation. Performance was determined by assessing calibration and discrimination (area under receiver operating characteristic curve (AUC)).

Results

Risk score performance varied across countries. In Iceland, for any unplanned hospital visits DIVERT and CARS reached a fair predictive value (AUC 0.74 [0.68–0.80] and AUC 0.74 [0.67–0.80]), respectively). In Finland, DIVERT had fair performance predicting ED visits (AUC 0.72 [0.67–0.77]) and any unplanned hospital visits (AUC 0.73 [0.67–0.77]). In other countries, AUCs did not exceed 0.70.

Conclusions

Geographical validation of risk scores predicting unplanned hospital visits in home care recipients showed substantial variations of poor to fair performance across countries. Unplanned hospital visits seem considerably dependent on healthcare context. Therefore, risk scores should be validated regionally before applied to practice. Future studies should focus on identification of more discriminative predictors in order to develop more accurate risk scores.

Homebound status among older adult home care recipients in Ontario, Canada

BACKGROUND

Homebound status is associated with an increased risk of morbidity and mortality in older adults, yet little is known about homebound older adults in Canada. Our objectives were to describe time trends in the prevalence of homebound status among community-dwelling long-term home care recipients and the characteristics associated with homebound status.

METHODS

This was a retrospective cross-sectional and cohort study using linked health administrative data in Canada's most populous province, Ontario. We included adults aged 65 years and older who received at least one long-term home care assessment from 2006 to 2017 (N = 666,514). Homebound individuals were those who exited the home an average of 0-1 days/week over the previous 30 days; not homebound comparators exited the home 2-7 days per week. We compared baseline characteristics between groups and estimated the association between these characteristics and homebound status at baseline and over time.

RESULTS

From 2006 to 2017, the annual proportion of long-term home care recipients who were homebound increased from 48% to 65%. At first assessment, 50% of the cohort (331,836 of 666,514) were homebound. Among those with a 4-12 month repeat assessment, homebound status persisted over time for 80%, and developed anew in 24%. Dependency on others for locomotion, use of an assistive device, poor access to dwelling, older age, and female sex were most strongly associated with homebound status at baseline, as well as its development and persistence over time.

CONCLUSIONS

We found that half of Ontario older adult long-stay home care clients were homebound at the time of their first assessment, and that the prevalence of homebound status among home care recipients rose steadily from 2006 to 2017. This informs further research and policy development to ensure the adequacy of supports for older homebound persons.

Development and validation of a prediction model of poor performance status and severe symptoms over time in cancer patients (PROVIEW+)

BACKGROUND

Predictive cancer tools focus on survival; none predict severe symptoms.

AIM

To develop and validate a model that predicts the risk for having low performance status and severe symptoms in cancer patients.

DESIGN

Retrospective, population-based, predictive study.

SETTING/PARTICIPANTS

We linked administrative data from cancer patients from 2008 to 2015 in Ontario, Canada. Patients were randomly selected for model derivation (60%) and validation (40%). Using the derivation cohort, we developed a multivariable logistic regression model to predict the risk of an outcome at 6 months following diagnosis and recalculated after each of four annual survivor marks. Model performance was assessed using discrimination and calibration plots. Outcomes included low performance status (i.e. 10-30 on Palliative Performance Scale), severe pain, dyspnea, well-being, and depression (i.e. 7-10 on Edmonton Symptom Assessment System).

RESULTS

We identified 255,494 cancer patients (57% female; median age of 64; common cancers were breast (24%); and lung (13%)). At diagnosis, the predicted risk of having low performance status, severe pain, well-being, dyspnea, and depression in 6-months is 1%, 3%, 6%, 13%, and 4%, respectively for the reference case (i.e. male, lung cancer, stage I, no symptoms); the corresponding discrimination for each outcome model had high AUCs of 0.807, 0.713, 0.709, 0.790, and 0.723, respectively. Generally these covariates increased the outcome risk by >10% across all models: lung disease, dementia, diabetes; radiation treatment; hospital admission; pain; depression; transitional performance status; issues with appetite; or homecare.

CONCLUSIONS

The model accurately predicted changing cancer risk for low performance status and severe symptoms over time.

Care home residents’ quality of life and its association with CQC ratings and workforce issues: the MiCareHQ mixed-methods study

Background

Care home staff have a critical bearing on quality. The staff employed, the training they receive and how well they identify and manage residents’ needs are likely to influence outcomes. The Care Act 2014 (Great Britain. The Care Act 2014. London: The Stationery Office; 2014) requires services to improve ‘well-being’, but many residents cannot self-report and are at risk of exclusion from giving their views. The Adult Social Care Outcomes Toolkit enables social care-related quality of life to be measured using a mixed-methods approach. There is currently no equivalent way of measuring aspects of residents’ health-related quality of life. We developed new tools for measuring pain, anxiety and depression using a mixed-methods approach. We also explored the relationship between care home quality, residents’ outcomes, and the skill mix and employment conditions of the workforce who support them.

Objectives

The objectives were to develop and test measures of pain, anxiety and depression for residents unable to self-report; to assess the extent to which regulator quality ratings reflect residents’ care-related quality of life; and to assess the relationship between aspects of the staffing of care homes and the quality of care homes.

Design

This was a mixed-methods study.

Setting

The setting was care homes for older adults in England.

Participants

Care home residents participated.

Results

Three measures of pain, anxiety and low mood were developed and tested, using a mixed-methods approach, with 182 care home residents in 20 care homes (nursing and residential). Psychometric testing found that the measures had good construct validity. The mixed-methods approach was both feasible and necessary with this population, as the majority of residents could not self-report. Using a combined data set (n = 475 residents in 54 homes) from this study and the Measuring Outcomes in Care Homes study (Towers AM, Palmer S, Smith N, Collins G, Allan S. A cross-sectional study exploring the relationship between regulator quality ratings and care home residents’ quality of life in England. Health Qual Life Outcomes 2019;17:22) we found a significant positive association between residents’ social care-related quality of life and regulator (i.e. Care Quality Commission) quality ratings. Multivariate regression revealed that homes rated ‘good/outstanding’ are associated with a 12% improvement in mean current social care-related quality of life among residents who have higher levels of dependency. Secondary data analysis of a large, national sample of care homes over time assessed the impact of staffing and employment conditions on Care Quality Commission quality ratings. Higher wages and a higher prevalence of training in both dementia and dignity-/person-centred care were positively associated with care quality, whereas high staff turnover and job vacancy rates had a significant negative association. A 10% increase in the average care worker wage increased the likelihood of a ‘good/outstanding’ rating by 7%.

Limitations

No care homes rated as inadequate were recruited to the study.

Conclusions

The most dependent residents gain the most from homes rated ‘good/outstanding’. However, measuring the needs and outcomes of these residents is challenging, as many cannot self-report. A mixed-methods approach can reduce methodological exclusion and an over-reliance on proxies. Improving working conditions and reducing staff turnover may be associated with better outcomes for residents.

Future work

Further work is required to explore the relationship between pain, anxiety and low mood and other indicators of care homes quality and to examine the relationship between wages, training and social care outcomes.

A Newly Identified Impairment in Both Vision and Hearing Increases the Risk of Deterioration in Both Communication and Cognitive Performance

Vision and hearing impairments are highly prevalent in adults 65 years of age and older. There is a need to understand their association with multiple health-related outcomes. We analyzed data from the Resident Assessment Instrument for Home Care (RAI-HC). Home care clients were followed for up to 5 years and categorized into seven unique cohorts based on whether or not they developed new vision and/or hearing impairments. An absolute standardized difference (stdiff) of at least 0.2 was considered statistically meaningful. Most clients (at least 60%) were female and 34.9 per cent developed a new sensory impairment. Those with a new concurrent vison and hearing impairment were more likely than those with no sensory impairments to experience a deterioration in receptive communication (stdiff = 0.68) and in cognitive performance (stdiff = 0.49). After multivariate adjustment, they had a twofold increased odds (adjusted odds ratio [OR] = 2.1; 95% confidence interval [CI]:1,87, 2.35) of deterioration in cognitive performance. Changes in sensory functioning are common and have important effects on multiple health-related outcomes.

Prevalence and Risk Factors of Breathlessness Across Canada: A National Retrospective Cohort Study in Home Care and Nursing Home Populations

CONTEXT

Breathlessness is a symptom associated with poor clinical outcomes and prognosis. Little is known about its long-term trends and associations with social factors including decline in social activities and caregiver distress.

OBJECTIVES

To describe factors associated with the prevalence of clinician-reported breathlessness across Canada among cohorts receiving home care or nursing home care.

METHODS

A retrospective observational cohort study of cross-sectional intake assessment data from Canadian interRAI Home Care and Nursing Home data sets. In each data set, we examined covariates associated with the presence of clinician-reported breathlessness using multivariate regression.

RESULTS

Between 2007 and 2018, we identified 1,317,117 and 469,709 individuals from the home care and nursing home data sets, respectively. Over two-thirds were aged >75 and over 60% were women. Breathlessness was present at intake in 26.0% of the home care and 8.2% of the nursing home cohorts. Between 2007 and 2018, prevalence of breathlessness increased by 10% for the home care cohort, while remaining relatively constant in nursing homes. Covariates associated with increased odds of having clinician-reported breathlessness at intake in both cohorts were moderate-severe impairment with activities of daily living, being male, older age, high pain scores, signs of depression, and decline in social activities. In the home care cohort, the presence of breathlessness was associated with a greater odds of caregiver distress (odds ratio = 1.19, 95% CI: 1.18-1.20).

CONCLUSION

The prevalence of clinician-reported breathlessness is higher in home care than in nursing home populations, the former having risen by 10% over the decade. Prevalence of breathlessness is associated with decline in social activities and caregiver distress. Enhanced supports may be required to meet increasing patient need in the community.

Developing a Fracture Risk Clinical Assessment Protocol for Long-Term Care: A Modified Delphi Consensus Process

OBJECTIVES

To develop a fracture risk Clinical Assessment Protocol (CAP) based on long-term care (LTC) fracture prevention recommendations and an embedded fracture risk assessment tool.

DESIGN

A modified Delphi consensus approach including 2 survey rounds and a face-to-face meeting was implemented to reach consensus on matching of LTC fracture prevention guideline statements to Fracture Risk Scale (FRS) risk levels.

SETTING AND PARTICIPANTS

A national panel of recognized experts in osteoporosis, fractures, and long-term care, including an LTC resident and family members.

METHODS

Round 1 survey respondents (n = 24) were provided the LTC fracture prevention guidelines matched to FRS risk levels and were asked whether they agreed the guideline was appropriate for the risk level (yes, no, I don't know, I agree with some but not all of it) and to provide comments. In round 2, guideline statements that did not achieve consensus (≥80% agreement) were revised consistent with comments provided in round 1 and respondents were asked again if they agreed with the guideline statement. Statements that did not achieve consensus were to be discussed and resolved in an in-person meeting (n = 17).

RESULTS

In round 1 (75% response rate), consensus was achieved in 7/14 guideline statements. In round 2 (56% response rate), 5 statements were revised based on round 1 feedback and for 2 statements additional information was provided. Consensus was achieved in all but one statement related to the inappropriateness of pharmacologic therapy for residents with life expectancy less than 1 year. Following facilitated meeting discussions, consensus was obtained to revise the guideline statement to reflect that life expectancy was but one of several criteria that should be used to inform medication decisions.

CONCLUSIONS AND IMPLICATIONS

An evidence-based fracture risk CAP was developed that will be embedded in international routine clinical assessment tools to guide fracture prevention in LTC.

Assessments of heart failure and frailty-related health instability provide complementary and useful information for home care planning and prognosis

BACKGROUND

Health instability, measured with the Changes in Health and End-stage disease Signs and Symptoms (CHESS) scale, predicts hospitalizations and mortality in home care clients. Heart failure (HF) is also common among home care clients. We seek to understand how HF contributes to the odds of death, hospitalization or worsening health among new home care clients depending on admission health instability.

METHODS

We undertook a retrospective cohort study of home care clients aged 65 years and older between January 1st 2010 and March 31st 2015 from Alberta, British Columbia, Ontario, and the Yukon, Canada. We used multistate Markov models to derive adjusted odds ratios (OR) for transitions to different health instability states, hospitalization, and death. We examined the role of HF and CHESS at 6 months after home care admission.

RESULTS

The sample included 286,232 clients. Those with HF had greater odds of worsening health instability than those without HF. At low-moderate admission health instability (CHESS 0-2), clients with HF had greater odds of hospitalization and death than those without HF. Clients with HF and high health instability (CHESS≥3) had slightly greater odds of hospitalization (OR 1.08, 95% Confidence Interval 1.02-1.13) but similar odds of death (OR 1.024, 95% CI 0.937-1.120) compared to clients without HF.

CONCLUSIONS

Among new home care clients, a HF diagnosis predicts death, hospitalization and worsening health, predominantly among those with low-moderate admission health instability. A HF diagnosis and admission CHESS score provide complementary information to support care planning in this population.

The Association of Anticholinergic Drugs and Delirium in Nursing Home Patients With Dementia: Results From the SHELTER Study

OBJECTIVES

Drugs with anticholinergic properties are associated with an increased prevalence of delirium, especially in older persons. The aim of this study was to evaluate the association between the use of this class of drugs in nursing home (NH) patients and prevalence of delirium, particularly in people with dementia.

DESIGN

Cross-sectional multicenter study.

SETTING AND PARTICIPANTS

3924 nursing home patients of 57 nursing homes in 7 European countries participating in the Services and Health for Elderly in Long TERmcare (SHELTER) project.

METHODS

Descriptive statistics, calculation of percentage, and multivariable logistic analysis were applied to describe the relationship between anticholinergic drug use and prevalence of delirium in NH patients. The Anticholinergic Risk Scale (ARS) and the Anticholinergic Burden Scale (ACB) were used to calculate the anticholinergic load.

RESULTS

54% of patients with dementia and 60% without dementia received at least 1 anticholinergic drug according to the ACB. The prevalence of delirium was higher in the dementia group (21%) compared with the nondementia group (11%). Overall, anticholinergic burden according to the ACB and ARS was associated with delirium both in patients with and without dementia, with odds ratios ranging from 1.07 [95% confidence interval (CI) 0.94-1.21] to 1.26 (95% CI 1.11-1.44). These associations reached statistical significance only in the group of patients with dementia. Among patients with dementia, delirium prevalence increased only modestly with increasing anticholinergic burden according to the ACB, from 20% (with none or minimal anticholinergic burden) to 25% (with moderate burden) and 27% delirium (with strong burden scores).

CONCLUSIONS AND IMPLICATIONS

The ACB scale is relatively capable to detect anticholinergic side effects, which are positively associated with prevalence of delirium in NH patients. Given the modest nature of this association, strong recommendations are currently not warranted, and more longitudinal studies are needed.

Psychometric Properties, Feasibility, and Acceptability of the Self-Reported interRAI Check-Up Assessment

OBJECTIVES

To assess the feasibility, acceptability, and psychometric properties of the self-report version of the interRAI Check-Up (CUSR).

DESIGN

Cross-sectional study of participant ratings of item content and difficulty completing the CUSR. Participants were also randomly assigned to complete the assessment by themselves or with help from a lay interviewer.

SETTINGS AND PARTICIPANTS

A total of 184 older adults from diverse backgrounds, served by 6 Canadian organizations in Ontario and Nova Scotia were recruited. Settings ranged from retirement communities for healthy older adults to assisted living facilities.

MEASURES/METHODS

Time to complete the interRAI CUSR was tracked automatically. Participants self-reported on what items they wanted to have modified, added, or deleted. The also rated whether items were embarrassing or difficult to complete. Psychometric properties were examined between the 2 approaches to completion and were benchmarked against existing reports on psychometric properties of clinician-led home care assessments.

RESULTS

The interRAI CUSR takes about 28 minutes to complete with both self-administered and lay interviewer approaches. The convergent validity and reliability of CUSR is comparable to those of clinician-based assessments like the Resident Assessment Instrument-Home Care. Most participants had no difficulty completing the assessment, and none rated the task as very difficult. Poor self-rated health and difficulty with phone use were predictive of any difficult in completing the assessment in a multivariate logistic regression. Most participants reported that CUSR adequately described their health needs, but arthritis, hypertension, and mental health issues were identified as items to be added by participants.

CONCLUSIONS AND IMPLICATIONS

The CUSR is an appropriate, feasible assessment system with good psychometric properties for use with general populations, including primary care, community services, and patient-reported outcome measurement studies. Interoperability with other interRAI assessments makes it an ideal system to use to obtain a longitudinal view of the person's needs over time.

Performance of the Cognitive Performance Scale of the Resident Assessment Instrument (interRAI) for Detecting Dementia amongst Older Adults in the Community

The Cognitive Performance Scale (CPS) in the widely used interRAI suite of instruments is of interest to clinicians and policy makers as a potential screening mechanism for detecting dementia. However, there has been little evaluation of the CPS in home care settings. This retrospective diagnostic study included 134 older adults (age ≥ 65) who were discharged from two acute psychogeriatric inpatient units or assessed in two memory clinics. The reference test was a diagnosis of clinical dementia, and the index test was interRAI CPS measured within 90 days of discharge. The overall accuracy of the CPS was good, with an area under the Receiver Operating Characteristic curve of 0.82 (95% CI = 0.75–0.89). The optimal cut point was 1/2, coinciding with the recommended cut point, with good sensitivity (0.90, 95% CI = 0.81–0.96) but poor specificity (0.60, 95% CI = 0.46–0.72). Positive predictive value improved from 0.72 (95% CI = 0.66–0.78) to 0.89 (95% CI = 0.75–0.96) when using a cut point of 2/3 instead of 1/2. If the results of the present study are replicated with more generalisable interRAI samples, older adults with a CPS of 3 or above, but without a formal diagnosis of dementia, should be referred for further cognitive assessment.

Benchmarking European Home Care Models for Older Persons on Societal Costs: The IBenC Study

This study aims to benchmark mean societal costs per client in different home care models and to describe characteristics of home care models with the lowest societal costs. In this prospective longitudinal study in 6 European countries, 6-month societal costs of resource utilization of 2060 older home care clients were estimated. Three care models were identified and compared based on level of patient-centered care (PCC), availability of specialized professionals (ASP) and level of monitoring of care performance (MCP). Differences in costs between care models were analyzed using linear regression while adjusting for case mix differences. Societal costs incurred in care model 2 (low ASP; high PCC & MCP) were significantly higher than in care model 1 (high ASP, PCC & MCP, mean difference €2230 (10%)) and in care model 3 (low ASP & PCC; high MCP, mean difference €2552 (12%)). Organizations within both models with the lowest societal costs, systematically monitor their care performance. However, organizations within one model arranged their care with a low focus on patient-centered care, and employed mainly generalist care professionals, while organizations in the other model arranged their care delivery with a strong focus on patient-centered care combined with a high availability of specialized care professionals.

Model-based two-way clustering of second-level units in ordinal multilevel latent Markov models

In this paper, an ordinal multilevel latent Markov model based on separate random effects is proposed. In detail, two distinct second-level discrete effects are considered in the model, one affecting the initial probability vector and the other affecting the transition probability matrix of the first-level ordinal latent Markov process. To model these separate effects, we consider a bi-dimensional mixture specification that allows to avoid unverifiable assumptions on the random effect distribution and to derive a two-way clustering of second-level units. Starting from a general model where the two random effects are dependent, we also obtain the independence model as a special case. The proposal is applied to data on the physical health status of a sample of elderly residents grouped into nursing homes. A simulation study assessing the performance of the proposal is also included.

Symptom trajectories of non-cancer patients in the last six months of life: Identifying needs in a population-based home care cohort

INTRODUCTION

The end-of-life symptom prevalence of non-cancer patients have been described mostly in hospital and institutional settings. This study aims to describe the average symptom trajectories among non-cancer patients who are community-dwelling and used home care services at the end of life.

MATERIALS AND METHODS

This is a retrospective, population-based cohort study of non-cancer patients who used home care services in the last 6 months of life in Ontario, Canada, between 2007 and 2014. We linked the Resident Assessment Instrument for Home Care (RAI-HC) (standardized home care assessment tool) and the Discharge Abstract Databases (for hospital deaths). Patients were grouped into four non-cancer disease groups: cardiovascular, neurological, respiratory, and renal (not mutually exclusive). Our outcomes were the average prevalence of these outcomes, each week, across the last 6 months of life: uncontrolled moderate-severe pain as per the Pain Scale, presence of shortness of breath, mild-severe cognitive impairment as per the Cognitive Performance Scale, and presence of caregiver distress. We conducted a multivariate logistic regression to identify factors associated with having each outcome respectively, in the last 6 months.

RESULTS

A total of 20,773 non-cancer patient were included in our study, which were analyzed by disease groups: cardiovascular (n = 12,923); neurological (n = 6,935); respiratory (n = 6,357); and renal (n = 3,062). Roughly 80% of patients were > 75 years and half were female. In the last 6 months of life, moderate to severe pain was frequent in the cardiovascular (57.2%), neurological (42.7%), renal (61.0%) and respiratory (58.3%) patients. Patients with renal disease had significantly higher odds for reporting uncontrolled moderate to severe pain (odds ratio [OR] = 1.21; 95% CI: 1.08 to 1.34) than those who did not. Patients with respiratory disease reported significantly higher odds for shortness of breath (5.37; 95% CI, 5.00 to 5.80) versus those who did not. Patients with neurological disease compared to those without were 9.65 times more likely to experience impaired cognitive performance and had 56% higher odds of caregiver distress (OR = 1.56; 95% CI: 1.43 to 1.71).

DISCUSSION

In our cohort of non-cancer patients dying in the community, pain, shortness of breath, impaired cognitive function and caregiver distress are important symptoms to manage near the end of life even in non-institutional settings.

The development and validation of a marginalization index for inpatient psychiatry

BACKGROUND

Marginalization is a multidimensional social construct that influences the mental health status of individuals and their use of psychiatric services. However, its conceptualization and measurement are challenging due to inconsistencies in definitions, and the lack of standard data sources to measure this construct.

AIMS

To create an index for screening marginalization based on an existing comprehensive assessment system used in inpatient psychiatry.

METHOD

Items anticipated to be indicative of marginalization were identified from the Resident Assessment Instrument-Mental Health (RAI-MH) that is used in all inpatient mental health beds in Ontario, Canada. Principal Component Analysis (PCA) and cluster analysis of these items was performed on a sample of 81,232 patients admitted into psychiatric care in Ontario between 1 January 2011 and 31 December 2016 to identify dimensions being measured. Various weights and scoring methods were tested to assess convergent validity on multiple outcomes of marginalization. Receiver Operating Characteristic (ROC) curve analysis was utilized to determine optimal cut-offs for the index by modeling the likelihood of different marginalization outcomes, including homelessness.

RESULTS

Fifteen items were identified for the development of the Marginalization Index (MI). PCA and cluster analysis identified that the items measured five dimensions. ROC curve analysis among homeless individuals identified an Area Under the Curve of 0.76 and an optimal cut-off of five on the MI. Frequency analysis of the index by different characteristics identified homeless individuals, frequent mental health service users, persons with a history of violence and police intervention, and persons with addictions issues, as groups with the highest scores, confirming the convergent validity of the index.

CONCLUSION

The MI is a valid measure of marginalization and is strong predictor of risk of homelessness among psychiatric inpatients. MI provides a resource that can be used for social and health policy, decision-support and evaluation.

Frailty of Māori, Pasifika, and Non-Māori/Non-Pasifika Older People in New Zealand: A National Population Study of Older People Referred for Home Care Services

BACKGROUND

Little is known about the prevalence of frailty in indigenous populations. We developed a frailty index (FI) for older New Zealand Māori and Pasifika who require publicly funded support services.

METHODS

An FI was developed for New Zealand adults aged 65 and older who had an interRAI Home Care assessment between June 1, 2012 and October 30, 2015. A frailty score for each participant was calculated by summing the number of deficits recorded and dividing by the total number of possible deficits. This created a FI with a potential range from 0 to 1. Linear regression models for FIs with ethnicity were adjusted for age and sex. Cox proportional hazards models were used to assess the association between the FI and mortality for Māori, Pasifika, and non-Māori/non-Pasifika.

RESULTS

Of 54 345 participants, 3096 (5.7%) identified as Māori, 1846 (3.4%) were Pasifika, and 49 415 (86.7%) identified as neither Māori nor Pasifika. New Zealand Europeans (48 178, 97.5%) constituted most of the latter group. Within each sex, the mean FIs for Māori and Pasifika were greater than the mean FIs for non-Māori and non-Pasifika, with the difference being more pronounced in women. The FI was associated with mortality (Māori subhazard ratio [SHR] 2.53, 95% CI 1.63-3.95; Pasifika SHR 6.03, 95% CI 3.06-11.90; non-Māori and non-Pasifika SHR 2.86, 95% CI 2.53-3.25).

CONCLUSIONS

This study demonstrated differences in FI between the ethnicities in this select cohort. After adjustment for age and sex, increases in FI were associated with increased mortality. This suggests that FI is predictive of poor outcomes in these ethnic groups.

Towards a standardized approach of assessing social context of persons receiving home care in Flanders, Belgium: the development and test of a social supplement to the interRAI instruments

BACKGROUND

Apart from a person's physical functioning, the early identification of social context indicators which affect patient outcomes - such as environmental and psychosocial issues - is key for high quality and comprehensive care at home. During a home care assessment, a person's biomedical and functional problems are typically considered. Harder to define concepts, such as psychosocial well-being or living arrangements, are not routinely documented, even though research shows they also affect functioning and health outcomes. The purpose of this study is to develop and test a concise, integrated assessment (BelRAI Social Supplement) that evaluates these social context indicators for persons receiving home care to complement existing interRAI- instruments.

METHODS

The development of the BelRAI Social Supplement is a multi-stage process, based upon the revised MRC-framework, involving both qualitative and quantitative research with stakeholders such as; clients, informal caregivers, care professionals and policy makers. The developmental process encompasses four stages: (I) item generation based on multiple methods and content validation by a panel of stakeholders (II) assessing feasibility and piloting methods, (III) early evaluation, and (IV) final evaluation. Stage II and III are covered in this paper.

RESULTS

During Stages I and II, a testable version of the BelRAI Social Supplement was developed in an iterative process. In Stage III, 100 care professionals assessed 743 individuals receiving home care in Flanders between December 2018 and December 2019. Using inter-item correlation matrixes, frequency distributions and regular feedback from the participants, the BelRAI Social Supplement was improved and prepared for Stage IV. The updated version of the instrument consists of four main sections: (1) environmental assessment; (2) civic engagement; (3) psychosocial well-being; and (4) informal care and support. In total, the BelRAI Social Supplement contains a maximum of 76 items.

CONCLUSIONS

The BelRAI Social Supplement was reviewed and shortened in close collaboration with care professionals and other experts in Flanders. This study resulted in an instrument that documents need-to-know social context determinants of home dwelling adults.

Adjusting Client-Level Risks Impacts on Home Care Organization Ranking

Quality indicators (QIs) based on the Resident Assessment Instrument-Home Care (RAI-HC) offer the opportunity to assess home care quality and compare home care organizations’ (HCOs) performance. For fair comparisons, providers’ QI rates must be risk-adjusted to control for different case-mix. The study’s objectives were to develop a risk adjustment model for worsening or onset of urinary incontinence (UI), measured with the RAI-HC QI bladder incontinence, using the database HomeCareData and to assess the impact of risk adjustment on quality rankings of HCOs. Risk factors of UI were identified in the scientific literature, and multivariable logistic regression was used to develop the risk adjustment model. The observed and risk-adjusted QI rates were calculated on organization level, uncertainty addressed by nonparametric bootstrapping. The differences between observed and risk-adjusted QI rates were graphically assessed with a Bland-Altman plot and the impact of risk adjustment examined by HCOs tertile ranking changes. 12,652 clients from 76 Swiss HCOs aged 18 years and older receiving home care between 1 January 2017, and 31 December 2018, were included. Eight risk factors were significantly associated with worsening or onset of UI: older age, female sex, obesity, impairment in cognition, impairment in hygiene, impairment in bathing, unsteady gait, and hospitalization. The adjustment model showed fair discrimination power and had a considerable effect on tertile ranking: 14 (20%) of 70 HCOs shifted to another tertile after risk adjustment. The study showed the importance of risk adjustment for fair comparisons of the quality of UI care between HCOs in Switzerland.

Lessons learned implementing and managing the DIVERT-CARE trial: practice recommendations for a community-based chronic disease self-management model

Background

Chronic disease management models of care provide an opportunity to assist home care clients to manage their disease burden. However, pragmatic trial management practices and lessons learned from such models are poorly illustrated in the literature.

Methods

We describe the processes of implementing a community-based cardiorespiratory self-management model, known as DIVERT-CARE, across the home care programs of three health regions in Canada. The DIVERT-CARE model is a multi-component complex intervention that identifies home care clients at the highest risk of deterioration and provides them with resources and capacity to manage their conditions. We conducted a retrospective analysis of baseline participant characteristics, needs assessments, reviewed findings from site visits and a national workshop with study partners, and examined other study documentation.

Results

Three home care regions in Canada participated in the study. A robust and data-driven review of each site was necessary to understand the local context, home care caseloads, structure of local systems, and intensity of resources, which influenced study processes. The creation of an intervention framework highlighted the need to adapt the intervention in a way that was sensitive to the local context while maintaining intervention outcomes.

Conclusion

Our detailed review showcases the relevant activities and on-the-ground steps needed to manage and conduct a multi-site pragmatic trial in home care. This example can help other researchers in implementing multi-disciplinary and multi-component care models for practice-based research.

Living with Dementia in Aotearoa (LiDiA): a cross-sectional feasibility study protocol for a multiethnic dementia prevalence study in Aotearoa/New Zealand

INTRODUCTION

Aotearoa/New Zealand (NZ) is officially recognised as a bicultural country composed of Māori and non-Māori. Recent estimations have projected a threefold increase in dementia prevalence in NZ by 2050, with the greatest increase in non-NZ-Europeans. The NZ government will need to develop policies and plan services to meet the demands of the rapid rise in dementia cases. However, to date, there are no national data on dementia prevalence and overseas data are used to estimate the NZ dementia statistics. The overall aim of the Living with Dementia in Aotearoa study was to prepare the groundwork for a large full-scale NZ dementia prevalence study.

METHODS AND ANALYSIS

The study has two phases. In phase I, we will adapt and translate the 10/66 dementia assessment protocol to be administered in Māori, Samoan, Tongan and Fijian-Indian elders. The diagnostic accuracy of the adapted 10/66 protocol will be tested in older people from these ethnic backgrounds who were assessed for dementia at a local memory service. In phase II, we will address the feasibility issues of conducting a population-based prevalence study by applying the adapted 10/66 protocol in South Auckland and will include NZ-European, Māori, Samoan, Tongan, Chinese and Fijian-Indian participants. The feasibility issues to be explored are as follows: (1) how do we sample to ensure we get accurate community representation? (2) how do we prepare a workforce to conduct the fieldwork and develop quality control? (3) how do we raise awareness of the study in the community to maximise recruitment? (4) how do we conduct door knocking to maximise recruitment? (5) how do we retain those we have recruited to remain in the study? (6) what is the acceptability of study recruitment and the 10/66 assessment process in different ethnic groups?

ETHICS AND DISSEMINATION

The validity and feasibility studies were approved by the New Zealand Northern A Health and Disability Ethics Committee (numbers 17NTA234 and 18NTA176, respectively). The findings will be disseminated through peer-reviewed academic journals, national and international conferences, and public events. Data will be available on reasonable request from the corresponding author.

Lonely in a crowd: loneliness in New Zealand retirement village residents

OBJECTIVES

The number of older people choosing to relocate to retirement villages (RVs) is increasing rapidly. This choice is often a way to decrease social isolation while still living independently. Loneliness is a significant health issue and contributes to overall frailty, yet RV resident loneliness is poorly understood. Our aim is to describe the prevalence of loneliness and associated factors in a New Zealand RV population.

DESIGN

A resident survey was used to collect demographics, social engagement, loneliness, and function, as well as a comprehensive geriatric assessment (international Resident Assessment Instrument [interRAI]) as part of the "Older People in Retirement Villages Study."

SETTING

RVs, Auckland, New Zealand.

PARTICIPANTS

Participants included RV residents living in 33 RVs (n = 578).

MEASUREMENTS

Two types of recruitment: randomly sampled cohort (n = 217) and volunteer sample (n = 361). Independently associated factors for loneliness were determined through multiple logistic regression with odds ratios (ORs).

RESULTS

Of the participants, 420 (72.7%) were female, 353 (61.1%) lived alone, with the mean age of 81.3 years. InterRAI assessment loneliness (yes/no question) was 25.8% (n = 149), and the resident survey found that 37.4% (n = 216) feel lonely sometimes/often/always. Factors independently associated with interRAI loneliness included being widowed (adjusted OR 8.27; 95% confidence interval [CI] 4.15-16.48), being divorced/separated/never married (OR 4.76; 95% CI 2.15-10.54), poor/fair quality of life (OR 3.37; 95% CI 1.43-7.94), moving to an RV to gain more social connections (OR 1.55; 95% CI 0.99-2.43), and depression risk (medium risk: OR 2.58, 95% CI 1.53-4.35; high risk: OR 4.20, 95% CI 1.47-11.95).

CONCLUSION

A considerable proportion of older people living in RVs reported feelings of loneliness, particularly those who were without partners, at risk of depression and decreased quality of life and those who had moved into RVs to increase social connections. Early identification of factors for loneliness in RV residents could support interventions to improve quality of life and positively impact RV resident health and well-being.

Trajectory of End-of-Life Pain and Other Physical Symptoms among Cancer Patients Receiving Home Care

PURPOSE

To describe the trajectory of physical symptoms among cancer decedents who were receiving home care in the six months before death.

PATIENTS AND METHODS

An observational cohort study of cancer decedents in Ontario, Canada, who received home care services between 2007 and 2014. To be included, decedents had to use at least one home care service in the last six months of life. Outcomes were the presence of pain and several other physical symptoms at each week before death.

RESULTS

Our cohort included 27,295 cancer decedents (30,368 assessments). Forty-seven percent were female and 56% were age 75 years or older. The prevalence of all physical symptoms increased as one approached death, particularly in the last month of life. In the last weeks of life, 69% of patients reported having moderate-severe pain; however, only 20% reported that the pain was not controlled. Loss of appetite (63%), shortness of breath (59%), high health instability (50%), and self-reported poor health (44%) were also highly prevalent in the last week of life. Multivariate regression showed that caregiver distress, high health instability, social decline, uncontrolled pain, and signs of depression all worsened the odds of having a physical symptom in the last 3 months of life.

CONCLUSION

In this large home care cancer cohort, trajectories of physical symptoms worsened close to death. While presence of moderate-severe pain was common, it was also reported as mostly controlled. Covariates, such as caregiver distress and social decline, were associated with having more physical symptoms at end of life.

Caregiving burnout of community-dwelling people with dementia in Hong Kong and New Zealand: a cross-sectional study

Background

Informal caregiving for people with dementia can negatively impact caregivers’ health. In Asia-Pacific regions, growing dementia incidence has made caregiver burnout a pressing public health issue. A cross-sectional study with a representative sample helps to understand how caregivers experience burnout throughout this region. We explored the prevalence and contributing factors of burnout of caregivers of community-dwelling older people with dementia in Hong Kong (HK), China, and New Zealand (NZ) in this study.

Methods

Analysis of interRAI Home Care Assessment data for care-recipients (aged ≥65 with Alzheimer’s disease/other dementia) who had applied for government-funded community services and their caregivers was conducted. The sample comprised 9976 predominately Chinese in HK and 16,725 predominantly European in NZ from 2013 to 2016. Caregiver burnout rates for HK and NZ were calculated. Logistic regression was used to determine the adjusted odds ratio (AOR) of the significant factors associated with caregiver burnout in both regions.

Results

Caregiver burnout was present in 15.5 and 13.9% of the sample in HK and NZ respectively. Cross-regional differences in contributing factors to burnout were found. Care-recipients’ ADL dependency, fall history, and cohabitation with primary caregiver were significant contributing factors in NZ, while primary caregiver being child was found to be significant in HK. Some common contributing factors were observed in both regions, including care-recipients having behavioural problem, primary caregiver being spouse, providing activities-of-daily-living (ADL) care, and delivering more than 21 h of care every week. In HK, allied-health services (physiotherapy, occupational therapy and speech therapy) protected caregiver from burnout. Interaction analysis showed that allied-health service attenuates the risk of burnout contributed by care-recipient’s older age (85+), cohabitation with child, ADL dependency, mood problem, and ADL care provision by caregivers.

Conclusions

This study highlights differences in service delivery models, family structures and cultural values that may explain the cross-regional differences in dementia caregiving experience in NZ and HK. Characteristics of caregiving dyads and their allied-health service utilization are important contributing factors to caregiver burnout. A standardized needs assessment for caregivers could help policymakers and healthcare practitioners to identify caregiving dyads who are at risk of burnout and provide early intervention.

Research in the retirement village community-The problems of recruiting a representative cohort of residents in Auckland, New Zealand

OBJECTIVES

Retirement villages are semi-closed communities, access usually being gained via village managers. This paper explores issues recruiting a representative resident cohort, as background to a study of residents, to acquire sociodemographic, health and disability data and trial an intervention designed to improve outcomes.

METHODS

We planned approaching all Auckland/Waitematā District villages and, via managers, contacting residents ('letter-drop'; 'door-knocks'). In 'small' villages (n ≤ 60 units), we planned contacting all residents, randomly selecting in 'larger' villages. We excluded those with doubtful or absent legal capacity.

RESULTS

We approached managers of 53 of 65 villages. Thirty-four permitted recruitment. Some prohibited 'letter-drops' and/or 'door-knocks'. Hence, we recruited volunteers (23 villages) via meetings, posters, newsletters and word-of-mouth, that is representative sampling obtained from 11/34 villages. We recruited 578 residents (median age = 82 years; 420 = female; 217:361 sampled:volunteers), finding differences in baseline parameters of sampled vs. volunteers.

CONCLUSION

Due to organisational/managers' policy, and national legislation restrictions, our sample does not represent our intended population well. Researchers should investigate alternative data sources, for example electoral rolls and censuses.

End-of-life outcomes with or without early palliative care: a propensity score matched, population-based cancer cohort study

OBJECTIVES

To investigate whether cancer decedents who received palliative care early (ie, >6 months before death) and not-early had different risk of using hospital care and supportive home care in the last month of life.

DESIGN/SETTING

We identified a population-based cohort of cancer decedents between 2004 and 2014 in Ontario, Canada using linked administrative data. Analysis occurred between August 2017 to March 2019.

PARTICIPANTS

We propensity-score matched decedents on receiving early or not-early palliative care using billing claims. We created two groups of matched pairs: one that had Resident Assessment Instrument (RAI) home care assessments in the exposure period (Yes-RAI group) and one that did not (No-RAI group) to control for confounders uniquely available in the assessment, such as health instability and pain. The outcomes were the absolute risk difference between matched pairs in receiving hospital care, supportive home care or hospital death.

RESULTS

In the No-RAI group, we identified 36 238 pairs who received early and not-early palliative care. Those in the early palliative care group versus not-early group had a lower absolute risk difference of dying in hospital (-10.0%) and receiving hospital care (-10.4%) and a higher absolute risk difference of receiving supportive home care (23.3%). In the Yes-RAI group, we identified 3586 pairs, where results were similar in magnitude and direction.

CONCLUSIONS

Cancer decedents who received palliative care earlier than 6 months before death compared with those who did not had a lower absolute risk difference of receiving hospital care and dying in hospital, and an increased absolute risk difference of receiving supportive home care in the last month of life.

Do premorbid characteristics of home care clients predict delayed discharges in acute care hospitals: a retrospective cohort study in Ontario and British Columbia, Canada

BACKGROUND

Improved identification of patients with complex needs early during hospitalisation may help target individuals at risk of delayed discharge with interventions to prevent iatrogenic complications, reduce length of stay and increase the likelihood of a successful discharge home.

METHODS

In this retrospective cohort study, we linked home care assessment records based on the Resident Assessment Instrument for Home Care (RAI-HC) of 210 931 hospitalised patients with their Discharge Abstract Database records. We then undertook multivariable logistic regression analyses to identify preadmission predictive factors for delayed discharge from hospital.

RESULTS

Characteristics that predicted delayed discharge included advanced age (OR: 2.72, 95% CI 2.55 to 2.90), social vulnerability (OR: 1.27, 95% CI 1.08 to 1.49), Parkinsonism (OR: 1.34, 95% CI 1.28 to 1.41) Alzheimer's disease and related dementias (OR: 1.27, 95% CI 1.23 to 1.31), need for long-term care facility services (OR: 2.08, 95% CI 1.96 to 2.21), difficulty in performing activities of daily living and instrumental activities of daily living, falls (OR: 1.16, 95% CI 1.12 to 1.19) and problematic behaviours such as wandering (OR: 1.29, 95% CI 1.22 to 1.38).

CONCLUSION

Predicting delayed discharge prior to or on admission is possible. Characteristics associated with delayed discharge and inability to return home are easily identified using existing interRAI home care assessments, which can then facilitate the targeting of pre-emptive interventions immediately on hospital admission.

Relationship between administrative characteristics of long-term care institutions and use of antipsychotics and anxiolytics in residents with cognitive impairment

OBJECTIVES

To identify the facility characteristics that are associated with prescribing practices of typical and atypical antipsychotics, and anxiolytics in residents with cognitive impairment in long-term care (LTC) institutions.

METHODS

A cross-sectional analysis of a country-representative sample of 23 LTC institutions in Poland was conducted in 2015-2016. Trained staff from each facility used the InterRAI-LTCF tool and drug dispensary cards on the day of resident's assessment to collect data on medication use from 455 residents with cognitive impairment. We used the anatomical therapeutic chemical classification and a multiple correspondence analysis.

RESULTS

We identified facility characteristics associated with higher rate of prescribing of: typical antipsychotics (nursing home, private ownership status, higher staff/bed ratio of physicians and nurses, and lower as refers to care assistants); atypical antipsychotics (residential home, public ownership status, higher staff/bed ratio of care assistants, and lower as refers to physicians); and anxiolytics (residential home, facilities of small size, public ownership status, higher staff/bed ratio of care assistants, lower of nurses and physicians). In the facilities where less residents received typical antipsychotics, anxiolytics were prescribed more often, and vice versa (rho = -0.442; p = 0.035).

CONCLUSION

This study showed a considerable variation in the use of typical and atypical antipsychotics, and anxiolytics between nursing and residential homes, which was associated with their organization (type, size, ownership status, and employment rate). We found a negative correlation between prescribing typical antipsychotics and anxiolytics, which made us aware that these medications may be used interchangeably in LTC facilities, despite the fact that both should be avoided.

Development and Validation of a Prediction Model for 6-Month Societal Costs in Older Community Care-Recipients in Multiple Countries; the IBenC Study

This study aims to develop and validate a prediction model of societal costs during a period of 6-months in older community care-recipients across multiple European countries. Participants were older community care-recipients from 5 European countries. The outcome measure was mean 6-months total societal costs of resource utilisation (healthcare and informal care). Potential predictors included sociodemographic characteristics, functional limitations, clinical conditions, and diseases/disorders. The model was developed by performing Linear Mixed Models with a random intercept for the effect of country and validated by an internal-external validation procedure. Living alone, caregiver distress, (I)ADL impairment, required level of care support, health instability, presence of pain, behavioural problems, urinary incontinence and multimorbidity significantly predicted societal costs during 6 months. The model explained 32% of the variation within societal costs and showed good calibration in Iceland, Finland and Germany. Minor model adaptations improved model performance in The Netherland and Italy. The results can provide a valuable orientation for policymakers to better understand cost development among older community care-recipients. Despite substantial differences of countries’ care systems, a validated cross-national set of key predictors could be identified.

Factors Associated With Hospital Presentation of Self-Harm Among Older Canadians in Long-Term Care: A 12-Year Cohort Study

OBJECTIVES

This study aimed to examine the incidence of, and factors associated with, hospital presentation for self-harm among older Canadians in long-term care (LTC).

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

The LTC data were collected using Resident Assessment Instrument-Minimum Data Set (RAI-MDS) and Resident Assessment Instrument-Home Care (RAI-HC), and linked to the Discharge Abstract Database (DAD) with hospital records of self-harm diagnosis. Adults aged 60+ at first assessment between April 1, 2003, and March 31, 2015, were included.

METHODS

Adjusted hazard ratios (HRs) of self-harm for potentially relevant factors, including demographic, clinical, and psychosocial characteristics, were calculated using Fine & Gray competing risk models.

RESULTS

Records were collated of 465,870 people in long-term care facilities (LTCF), and 773,855 people receiving home care (HC). Self-harm incidence per 100,000 person-years was 20.76 [95% confidence interval (CI) 20.31-25.40] for LTCF and 46.64 (44.24-49.12) for HC. In LTCF, the strongest risks were younger age (60-74 years vs 90+: HR, 6.00; 95% CI, 3.24-11.12), psychiatric disorders (bipolar disorder: 3.46; 2.32-5.16; schizophrenia: 2.31; 1.47-3.62; depression: 2.29; 1.80-2.92), daily severe pain (2.01; 1.30-3.11), and daily tobacco consumption (1.78; 1.29-2.45). For those receiving HC, the strongest risk factors were younger age (60-74 years vs 90+: 2.54; 1.97-3.28), psychiatric disorders (2.20; 1.93-2.50), daily tobacco consumption (2.08; 1.81-2.39), and frequent falls (1.98; 1.46-2.68). All model interactions between setting and factors were significant.

CONCLUSIONS AND IMPLICATIONS

There was lower incidence of hospital presentation for self-harm for LTCF residents than HC recipients. We found sizable risks of self-harm associated with several modifiable risk factors, some of which can be directly addressed by better treatment and care (psychiatric disorders and pain), whereas others require through more complex interventions that target underlying factors and causes (tobacco and falls). The findings highlight a need for setting- and risk-specific prevention strategies to address self-harm in the older populations.

Five-year risk of admission to long-term care home and death for older adults given a new diagnosis of dementia: a population-based retrospective cohort study

BACKGROUND

After diagnosis of a health condition, information about survival and potential transition from community into institutional care can be helpful for patients and care providers. We sought to describe the association between a new diagnosis of dementia and risk of admission to a long-term care home and death at 5 years.

METHODS

We conducted a population-based retrospective cohort study using linked health administrative databases. We identified individuals aged 65 years or older, living in the community, with a first documented diagnosis of dementia between Jan. 1, 2010, and Dec. 31, 2012, in Ontario, Canada. Dementia diagnosis was captured using diagnostic codes from hospital discharges, physician billings, assessments conducted for home care and long-term care, and dispensed prescriptions for cholinesterase inhibitors. Our primary outcome measures were 5-year risk of death and placement in a long-term care home, adjusted for sociodemographic and clinical factors.

RESULTS

We identified 108 757 individuals in our study cohort. By the end of 5 years, 24.4% remained alive in the community and 20.5% were living in a long-term care home. Of the 55.1% who died, about half (27.9%) were admitted to a long-term care home before death. Three risk factors were associated with increased odds of death: older age (age ≥ 90 yr; odds ratio [OR] 9.5, 95% confidence interval [CI] 8.8-10.2 [reference: age 65-69 yr]), male sex (OR 1.7, 95% CI 1.6-1.7), and the presence of organ failure, including chronic obstructive pulmonary disease (OR 1.7, 95% CI 1.7-1.8), congestive heart failure (OR 2.0, 95% CI 1.9-2.0) and renal failure (OR 1.7, 95% CI 1.6-1.8). Groups formed by combinations of these 3 factors had an observed 5-year risk of death varying between 22% and 91%.

INTERPRETATION

Among community-dwelling older adults with newly identified dementia in Ontario, the majority died or were admitted to a long-term care home within 5 years. This information may be helpful for discussions on prognosis and need for admission to long-term care.

Linking the Scores of the Montreal Cognitive Assessment 5-min and the interRAI Cognitive Performance Scale in Older Adults With Mild Physical or Cognitive Impairment

Background: Bridging scores generated from different cognitive assessment tools is necessary to efficiently track changes in cognition across the continuum of care. This study linked scores from the Montreal Cognitive Assessment-5 min (MoCA 5-min) to the interRAI cognitive Performance Scale (CPS), commonly adopted tools in clinical and long-term care settings, respectively. Methods: We included individual-level data from persons who participated in a home- and community-based care program for older people with mild impairment in Hong Kong. The program used the interRAI-Check Up instrument for needs assessment and service matching between 2017 and 2020. Each participant's cognitive performance was assessed using CPS, CPS Version 2 (CPS2), and MoCA 5-min. We performed equipercentile linking with bivariate log-linear smoothing to establish equivalent scores between the two scales. Results: 3,543 participants had valid data on both scales; 66% were female and their average age was 78.9 years (SD = 8.2). The mean scores for MoCA 5-min, CPS, and CPS2 were 18.5 (SD = 5.9), 0.7 (SD = 0.7), and 1.3 (SD = 1.1), respectively. A CPS or CPS2 score of 0 (intact cognition) corresponds to MoCA 5-min scores of 24 and 25, respectively. At the higher end, a CPS score of 3 (moderately impaired) and a CPS2 score of 5 (moderately impaired Level-2) corresponded to MoCA 5-min scores of 0 and 1, respectively. The linking functions revealed the floor and ceiling effects that exist for the different scales, with CPS and CPS2 measuring more-severe cognitive impairment while the MoCA 5-min was better suited to measure mild impairment. Conclusions: We provided score conversions between MoCA 5-min and CPS/CPS2 within a large cohort of Hong Kong older adults with mild physical or cognitive impairment. This enabled continuity in repeated assessment with different tools and improved comparability of cognitive scores generated from different tools from diverse populations and research cohorts.

An Examination of Correlates of Quality of Life in Children and Youth With Mental Health Issues

Quality of life (QoL) is significantly lower in children with mental health issues compared to those who are typically developing or have physical health problems. However, little research has examined factors associated with QoL in this particularly vulnerable population. To address this limitation, 347 clinically referred children and adolescents were assessed using the interRAI Child and Youth Mental Health (ChYMH) Assessment and Self-reported Quality of Life- Child and Youth Mental Health (QoL-ChYMH). Hierarchical multiple linear regression analyses were conducted to examine QoL at the domain-specific level. Children and adolescents who experienced heightened anhedonia and depressive symptoms reported lower social QoL (e.g., family, friends and activities; p = 0.024, 0.046, respectively). Additionally, children and youth who experienced heightened depressive symptoms reported lower QoL at the individual level (e.g., autonomy, health; p = 0.000), and level of basic needs (e.g., food, safety; p = 0.013). In contrast, no mental state indicators were associated with QoL related to services (e.g., school, treatment). Due to the paucity of research examining predictors of QoL in children and youth with mental health challenges, this study contributes to the field in assisting service providers with care planning and further providing implications for practice.

Brief Report: Characteristics and Needs of Persons Admitted to an Inpatient Psychiatric Hospital With Workers' Compensation Coverage

The rise of mental health issues in the workplace is widely known. Though mental health issues were not covered by the Workplace Safety Insurance Board (WSIB) in Ontario (Canada) until 2018, it was listed as responsible for payment of inpatient psychiatric hospital stays between 2006 and 2016. This population-level observational analytic study compares the clinical and service needs of 1,091 individuals admitted to inpatient psychiatry with WSIB coverage to all other admissions (n = 449,128). Secondary analysis was based on the interRAI Mental Health assessment. The WSIB group differed from all other admissions on almost all characteristics considered. Most notably, depression (65.08 vs. 57.02%), traumatic life events (25.48 vs. 15.58%), substance use (58.02 vs. 46.92%), daily pain (38.31 vs. 12.15%) and sleep disturbance (48.95 vs. 37.12%) were much higher in the WSIB group. Females with WSIB coverage had more depression (74.36 vs. 59.91%) and traumatic life events (30.00 vs. 22.97%), whereas males had more substance issues (63.62 vs. 47.95%). In addition, persons under the age of 55 had more substance issues (<25 = 75.47%; 25-54 = 61.64%: 55 ± 40.54%) and traumatic life events (<25 = 26.41%; 25-54 = 28.18%; 55 ± 15.31%), while those 25-54 years had more daily pain (41.67% vs. <25 = 3.77% and 55 ± 34.23%) and sleep disturbance (50.74% vs. <25 = 33.96% and 55 ± 45.94%). All variables differed significantly by sex and age within the comparison group, though not always following the patterns observed in the WSIB group. Future research examining mental health needs and outcomes among injured workers receiving inpatient psychiatric services is needed, and should take into account sex and age.

A Cross-Sectoral Comparison of Prevalence and Predictors of Symptoms of Depression Over Time Among Older Adults in Ontario, Canada

OBJECTIVES

Late-life depression, a common mental health issue, poses a significant burden of illness globally. We investigated factors associated with symptoms of depression among older adults across 3 health sectors in Ontario, Canada.

METHOD

Electronic health assessment data on older adults aged 60 years+ in home care (HC; N = 359 217), long-term care (LTC; N = 125 496), and palliative care (PC; N = 29 934) were examined. Change in symptoms of depression, measured using the interRAI Depression Rating Scale (DRS), over time was examined, including predictors of the development of depression.

RESULTS

At baseline, symptoms of depression were observed in 19.1% (HC), 24.2% (LTC), and 11.9% (PC). This increased to 20.6% (HC), 33.8% (LTC), and 13.2% (PC) at follow-up. For most older adults, DRS scores remained the same across sectors over time. Three independent variables emerged consistently across sectors as the main risk and protective factors for symptoms of depression.

CONCLUSION

Although variations in the risk and protective factors for late-life depression were demonstrated across each sector, some commonalities emerged including unmanaged pain, symptoms of depression at baseline, social connectedness, and activity.

The Forensic Supplement to the interRAI Mental Health Assessment Instrument: Evaluation and Validation of the Problem Behavior Scale

Background: Numerous validation studies support the use of the interRAI Mental Health (MH) assessment system for inpatient mental health assessment, triage, treatment planning, and outcome measurement. However, there have been suggestions that the interRAI MH does not include sufficient content relevant to forensic mental health. We address this potential deficiency through the development of a Forensic Supplement (FS) to the interRAI MH system. Using three forensic risk assessment instruments (PCL-R; HCR-20; VRAG) that had a record of independent cross validation in the forensic literature, we identified forensic content domains that were missing in the interRAI MH. We then independently developed items to provide forensic coverage. The resulting FS is a single-page, 19-item supplementary document that can be scored along with the interRAI MH, adding approximately 10-15 min to administration time. We constructed the Problem Behavior Scale (PBS) using 11 items from the interRAI MH and FS. The Developmental Sample, 168 forensic mental health inpatients from two large mental health specialty hospitals, was assessed with both an earlier version of the interRAI MH and FS. This sample also provided us access to scores on the PCL-R, the HCR-20 and the VRAG. To validate our initial findings, we sought additional samples where scoring of the interRAI MH and the FS had been done. The first, the Forensic Sample (N = 587), consisted of forensic inpatients in other mental health units/hospitals. The second, the Correctional Sample (N = 618) was a random, representative sample of inmates in prisons, and the third, the Youth Sample (N = 90) comprised a group of youth in police custody. Results: The PBS ranged from 0 to 11, was positively skewed with most scores below 3, and had good internal consistency (Cronbach's Alpha = 0.80). In a test of concurrent validity, correlations between PBS scores and forensic risk scores were moderate to high (i.e., r with PCL-R Factor two of 0.317; with HCR-20 Clinical of 0.46; and with HCR-20 Risk of 0.39). In a test of convergent validity, we used Binary Logistic Regression to demonstrate that the PBS was related to three negative patient experiences (recent verbal abuse, use of a seclusion room, and failure to attain an unaccompanied leave). For each of these three samples, we conducted the same convergent validity statistical analyses as we had for the Developmental Sample and the earlier findings were replicated. Finally, we examined the relationship between PBS scores and care planning triggers, part of the interRAI systems Clinical Assessment Protocols (CAPs). In all three validity samples, the PBS was significantly related to the following CAPs being triggered: Harm to Others, Interpersonal Conflict, Traumatic Life Events, and Control Interventions. These additional validations generalize our findings across age groups (adult, youth) and across health care and correctional settings. Conclusions: The FS improves the interRAI MH's ability to identify risk for negative patient experiences and assess clinical needs in hospitalized/incarcerated forensic patients. These results generalize across age groups and across health care and correctional settings.

Older Emergency Department Patients: Does Baseline Care Status Matter?

Background

Little is known about the prognostic differences between older emergency department (ED) patients who present with different formal support requirements in the community. We set out to describe and compare the patient profiles and patterns of health service use among three older ED cohorts: home care clients, nursing home residents and those receiving no formal support.

Methods

We conducted a secondary analysis of the Canadian cohort from the interRAI multinational ED study. Data were collected using interRAI ED contact assessment on patients 75 years of age and older (n = 2,274), in eight ED sites across Canada. A series of descriptive statistics were reported. Adjusted associations were determined using logistic regression.

Results

Older adults receiving no formal support services were most stable. However, they were most likely to be hospitalized. Older home care clients were most likely to report depressive symptoms and distressed caregivers. They also had the greatest odds of frequent ED visitation post-discharge (OR=1.9; 95% CI=1.39–2.59). Older adults transferred from a nursing home were the frailest but had the lowest odds of hospital admission (OR=0.14; 95% CI=0.09–0.23).

Conclusion

We demonstrated the importance of inquiring about community-based formal support services and provide data to support decision-making in the ED.

Adaptation and Feasibility of the interRAI Family Carer Needs Assessment in a Pediatric Setting

Family carers of children with serious illness contribute many hours of medical care in addition to usual daily care. Assessing the needs and supports of family carers is not routine practice. This study is the first to utilize the interRAI Family Carer Needs Assessment in carers of children, seeking to evaluate and improve its ability to capture their needs. This is a prospective pilot study of family carers of children with serious illness receiving care at a pediatric hospice. Thirty carers completed the self-assessment form. Additional feedback was sought inquiring about the appropriateness of questions and missing information relevant to the pediatric setting. All participants reported the assessment captured important information across multiple domains. Additional questions surrounding extra costs, home and school supports, as well as direct impacts of caregiving activities on pain and relationships were identified as important adaptations. The most common unmet needs in carers and care recipients were episodic relief from caregiving (n=17) and housing adaptation (n=17), respectively. Overall, a comprehensive assessment form is feasible in identifying the diverse needs of family carers of children. Future research should focus on using pediatric specific interRAI tools to guide improvements in policy and practice that can address unmet needs.

Impact of COVID-19 on the health and psychosocial status of vulnerable older adults: study protocol for an observational study

BACKGROUND

Many countries around the world have adopted social distancing as one of the public health measures to reduce COVID-19 transmissions in the community. Such measures could have negative effects on the mental health of the population. The aims of this study are to (1) track the impact of COVID-19 on self-reported mood, self-rated health, other health and psychosocial indicators, and health services utilization of people who have an interRAI assessment during the first year of COVID-19; (2) compare these indicators with the same indicators in people who had an interRAI assessment in the year before COVID-19; and (3) report these indicators publicly as soon as data analysis is completed every 3 months.

METHODS

interRAI COVID-19 Study (iCoS) is an observational study on routinely collected national data using the interRAI Home Care and Contact Assessment, which are standardized geriatric assessment tools mandated for all people assessed for publicly funded home support services and aged residential care in New Zealand. Based on the 2018/19 figures, we estimated there are 36,000 interRAI assessments per annum. We will compare the four post-lockdown quarters (from 25th March 2020) with the respective pre-lockdown quarters. The primary outcomes are self-reported mood (feeling sad, depressed or hopeless: 0 = no, 1 = yes) and self-rated health (0 = excellent, 1 = good, 2 = fair, 3 = poor). We will also analyze sociodemographics, other secondary health and psychosocial indicators, and health services utilization. Descriptive statistics will be conducted for primary outcomes and other indicators for each of the eight quarters. We will compare the quarters using regression models adjusted for demographic characteristics using weights or additional variables. Key health and psychosocial indicators will be reported publicly as soon as data analysis is completed for each quarter in the 12-month post-lockdown period by using a data visualization tool.

DISCUSSION

This rapid translation of routinely collected national interRAI data will provide a means to monitor the health and psychosocial well-being of vulnerable older New Zealanders. Insights from this study can be shared with other countries that use interRAI and prepare health and social services for similar epidemics/pandemics in the future.

The relationship of nursing home price and quality of life

Background

Knowledge about the relationship between the residents’ Quality of Life (QOL) and the nursing home price is currently lacking. Therefore, this study investigates the relationship between 11 dimensions of QOL and nursing homes price in Flemish nursing homes.

Methods

The data used in this cross-sectional study were collected by the Flemish government from years 2014 to 2017 and originates from 659 Flemish nursing homes. From 2014 to 2016, data on the QOL of 21,756 residents was assessed with the InterRAI instrument. This instrument contains 11 QOL dimensions. Multiple linear regression analyses were conducted to examine the research question.

Results

The multiple linear regressions indicated that a 10 euro increase in the daily nursing home price is associated with a significant decrease (P <  0.001) of 0.1 in 5 dimensions of QOL (access to services, comfort and environment, food and meals, respect, and safety and security). Hence, our results indicate that the association between price and QOL is very small. When conducting a subgroup analysis based on ownership type, the earlier found results remained only statistically significant for private nursing homes.

Conclusion

Our findings show that nursing home price is of limited importance with respect to resident QOL. Contrary to popular belief, our study demonstrates a limited negative effect of price on QOL. Further research that includes other indicators of QOL is needed to allow policymakers and nursing home managers to improve nursing home residents’ QOL.

An interRAI-derived frailty index is associated with prior hospitalisations in older adults residing in retirement villages

OBJECTIVES

To develop and validate a frailty index (FI) from interRAI-Community Health Assessments (CHA) on older adults in retirement villages (RVs).

METHODS

This is a cross-sectional analysis of a current RV research study. A FI was generated using the cumulative deficit model. Health-care utilisation measures were acute, and all, hospitalisations 12 months before baseline assessment. Associations between FI and hospitalisations were explored using multivariable logistic regression to estimate odds ratio (OR).

RESULTS

Of 577 included residents, mean (SD) age was 81 (7) and 419 (73%) were female. Mean (SD) FI was 0.16 (0.09); 260 (45%) were mildly frail, and 108 (19%) moderate-severely frail. In multivariate-adjusted analysis, odds of acute hospitalisation for mild (OR = 3.3, P < .001) and moderate-severely frail (OR = 6.4, P < .001) were significantly higher than fit residents. Higher odds were also observed for all hospitalisations.

CONCLUSION

A considerable proportion of RV residents were moderately-severely frail. FI was associated with acute and all hospitalisations.

Evaluating the Effect of COVID-19 Pandemic Lockdown on Long-Term Care Residents' Mental Health: A Data-Driven Approach in New Brunswick

Long-term care (LTC) residents, isolated because of the COVID-19 pandemic, are at increased risk for negative mental health outcomes. The purpose of our article is to demonstrate how the interRAI LTC facility (LTCF) assessment can inform clinical care and evaluate the effect of strategies to mitigate worsening mental health outcomes during the COVID-19 pandemic. We present a supporting analysis of the effects of lockdown in homes without COVID-19 outbreaks on depression, delirium, and behavior problems in a network of 7 LTC homes in New Brunswick, Canada, where mitigative strategies were deployed to minimize poor mental health outcomes (eg, virtual visits and increased student volunteers). This network meets regularly to review performance on risk-adjusted quality of care indicators from the interRAI LTCF and share learning through a community of practice model. We included 4209 assessments from 765 LTC residents between January 2017 to June 2020 and modeled the change within and between residents for depression, delirium, and behavioral problems over time with longitudinal generalized estimating equations. Though the number of residents who had in-person visits with family decreased from 73.2% before to 17.9% during lockdown (chi square, P < .001), the number of residents experiencing delirium (4.5%-3.5%, P = .51) and behavioral problems (35.5%-30.2%, P = .19) did not change. The proportion of residents with indications of depression decreased from 19.9% before to 11.5% during lockdown (P < .002). The final multivariate models indicate that the effect of lockdown was not statistically significant on depression, delirium, or behavioral problems. Our analyses demonstrate that poor mental health outcomes associated with lockdown can be mitigated with thoughtful intervention and ongoing evaluation with clinical information systems. Policy makers can use outputs to guide resource deployment, and researchers can examine the data to identify better management strategies for when pandemic strikes again.

External validation of the detection of indicators and vulnerabilities for emergency room trips (DIVERT) scale: a retrospective cohort study

Background

The Detection of Indicators and Vulnerabilities of Emergency Room Trips (DIVERT) scale was developed to classify and estimate the risk of emergency department (ED) use among home care clients. The objective of this study was to externally validate the DIVERT scale in a secondary population of home care clients.

Methods

We conducted a retrospective cohort study, linking data from the Home Care Reporting System and the National Ambulatory Care Reporting System. Data were collected on older long-stay home care clients who received a RAI Home Care (RAI-HC) assessment. Data were collected for home care clients in the Canadian provinces of Ontario and Alberta, as well as in the cities of Winnipeg, Manitoba and Whitehorse, Yukon Territories between April 1, 2011 and September 30, 2014. The DIVERT scale was originally derived from the items of the RAI-HC through the use of recursive partitioning informed by a multinational clinical panel. This scale is currently implemented alongside the RAI-HC in provinces across Canada. The primary outcome of this study was ED visitation within 6 months of a RAI-HC assessment.

Results

The cohort contained 1,001,133 home care clients. The vast majority of cases received services in Ontario (88%), followed by Alberta (8%), Winnipeg (4%), and Whitehorse (< 1%). Across the four cohorts, the DIVERT scale demonstrated similar discriminative ability to the original validation work for all outcomes during the six-month follow-up: ED visitation (AUC = 0.617–0.647), two or more ED visits (AUC = 0.628–0.634) and hospital admission (AUC = 0.617–0.664).

Conclusions

The findings of this study support the external validity of the DIVERT scale. More specifically, the predictive accuracy of the DIVERT scale from the original work was similar to the accuracy demonstrated within a new cohort, created from different geographical regions and time periods.
