Effect of preventive primary care outreach on health related quality of life among older adults at risk of functional decline: randomised controlled trial.

OBJECTIVE: To evaluate the impact of a provider initiated primary care outreach intervention compared with usual care among older adults at risk of functional decline. DESIGN: Randomised controlled trial. SETTING: Patients enrolled with 35 family physicians in five primary care networks in Hamilton, Ontario, Canada. PARTICIPANTS: Patients were eligible if they were 75 years of age or older and were not receiving home care services. Of 3166 potentially eligible patients, 2662 (84%) completed the validated postal questionnaire used to determine risk of functional decline. Of 1724 patients who met the risk criteria, 769 (45%) agreed to participate and 719 were randomised. INTERVENTION: The 12 month intervention, provided by experienced home care nurses in 2004-6, consisted of a comprehensive initial assessment using the resident assessment instrument for home care; collaborative care planning with patients, their families, and family physicians; health promotion; and referral to community health and social support services. MAIN OUTCOME MEASURES: Quality adjusted life years (QALYs), use and costs of health and social services, functional status, self rated health, and mortality. RESULTS: The mean difference in QALYs between intervention and control patients during the study period was not statistically significant (0.017, 95% confidence interval -0.022 to 0.056; P=0.388). The mean difference in overall cost of prescription drugs and services between the intervention and control groups was not statistically significant, (-$C165 ( pound107; euro118; $162), 95% confidence interval -$C16 545 to $C16 214; P=0.984). Changes over 12 months in functional status and self rated health were not significantly different between the intervention and control groups. Ten patients died in each group. CONCLUSIONS: The results of this study do not support adoption of this preventive primary care intervention for this target population of high risk older adults. Trial registration Clinical trials NCT00134836.

Risk factors for falling among community-based seniors.

BACKGROUND: Falling constitutes a significant risk to the health and well-being of seniors. Although a number of risk factors have been established within the literature for falling, limited work has differentiated risk factors for 1-time versus recurrent or multiple fallers. METHODS: The purpose of this research was to examine 2 relationships: (1) the risk factors for nonfallers versus fallers (1+ falls); and (2) the risk factors for nonfallers/1-time fallers versus multiple fallers (2+ falls). All participants (n = 453) were subjects within 5 different fall intervention programs funded through the Falls Prevention Initiative sponsored by Health Canada and Veterans Affairs Canada. In total, 5 project sites funded in Ontario conducted independent fall intervention programs. At the onset of their programs and at the completion of their programs, each project site assessed all of their subjects or a predetermined number of seniors (if the subject pool was extensive) using 2 instruments, namely the interRAI Community Health Assessment and the Berg Balance Scale, so that comparisons could be made between sites. RESULTS: Of the 453 individuals, 67% of the sample was classified as nonfallers, with 33% classified as experiencing 1 or more falls. Risk factors significant within the model examining nonfallers versus 1+ fallers included increased medication use and a previous history of falling. For the second analyses, examining 0 falls/1 fall versus recurrent fallers, the following factors were associated with increased risk: medication use, previous history of falling, and compromised activities of daily living (ADL). Fourteen percent of the sample experienced 2+ falls. CONCLUSIONS: It is important to distinguish fallers based on fall status because recurrent or multiple fallers are more likely to benefit from fall prevention efforts. Using a standardized and comprehensive tool such as the interRAI-CHA would assist researchers in making comparisons between different research groups.

The prevalence and management of current daily pain among older home care clients.

The aim of this cross-sectional study was to examine the prevalence and correlates of pharmacotherapy for current daily pain in older home care clients, focusing on analgesic type and potential contraindications to treatment. The sample included 2779 clients aged 65+years receiving services from Community Care Access Centres in Ontario during 1999-2001. Clients were assessed with the Resident Assessment Instrument-Home Care (RAI-HC). Prescription and over-the-counter (OTC) medications listed on the RAI-HC were used to categorize analgesic treatment into two groups (relative to no analgesic use): use of non-opioids (acetaminophen or non-steroidal anti-inflammatory drugs only); and, use of opioids alone or in combination with non-opioids. Associations between client characteristics and analgesic treatment among those in current daily pain were examined using multivariable multinomial logistic regression. Approximately 48% (n=1,329) of clients had daily pain and one-fifth (21.6%) of this group received no analgesic. In multivariable analyses, clients aged 75+years and those with congestive heart failure, diabetes, other disease-related contraindications, cognitive impairment and/or requiring an interpreter were significantly less likely to receive an opioid alone or in combination with a non-opioid. Clients with congestive heart failure and without a diagnosis of arthritis were significantly less likely to receive a non-opioid alone. A diagnosis of arthritis or cancer and use of nine or more medications were significantly associated with opioid use. The findings provide evidence of both rational prescribing practices and potential treatment bias in the pharmacotherapeutic management of daily pain in older home care clients.

The relationship between agency characteristics and quality of home care.

BACKGROUND: This project assessed the relationship between home care quality indicators (HCQIs) and agency characteristics. METHODS: Twelve agencies completed a mailed survey on a variety of characteristics, including size of their caseload and for-profit (FP) status of contracted service providers. The HCQIs were derived from standardized assessments completed voluntarily for home care clients in Ontario and in Manitoba, Canada. RESULTS: The average caseload was 121.3 clients per case manager, and over 40% of nursing, personal support and therapy providers were considered FP. For individual HCQIs, few correlations were statistically significant. An overall summary measure of quality was correlated with the size of the population served (r = -0.80; p < 0.05) and the number of clients per case manager (r = -0.56; p < 0.1). CONCLUSION: These data represent unique information on home care quality and organizational characteristics in Canada. The question remains as to how best to use HCQI data to inform practice in an era of limited resources and increasing caseloads.

Potentially inappropriate management of depressive symptoms among Ontario home care clients.

OBJECTIVE: To examine the prevalence and correlates of potentially inappropriate pharmacotherapy (including potential under-treatment) for depression in adult home care clients. METHODS: A cross-sectional study of clients receiving services from Community Care Access Centres in Ontario. Three thousand three hundred and twenty-one clients were assessed with the Resident Assessment Instrument for Home Care (RAI-HC). A score of 3 or greater on the Depression Rating Scale (DRS), a validated scale embedded within the RAI-HC, indicates the presence of symptoms of depression. Medications listed on the RAI-HC were used to categorize treatment into two groups: potentially appropriate and potentially inappropriate antidepressant drug therapy. Adjusted logistic regression models were used to explore relevant predictors of potentially inappropriate pharmacotherapy. RESULTS: 12.5% (n=414) of clients had symptoms of depression and 17% received an appropriate antidepressant. Over half of clients (64.5%) received potentially inappropriate pharmacotherapy (including potential under-treatment). Age 75 years or older, higher levels of caregiver stress and the presence of greater comorbidity were associated with a higher risk of potentially inappropriate pharmacotherapy in multivariate analyses. Documentation of any psychiatric diagnosis on the RAI-HC and receiving more medications were significantly associated with a greater likelihood of appropriate drug treatment. CONCLUSION: Most clients with significant depressive symptoms were not receiving appropriate pharmacotherapy. Having a documented diagnosis of a psychiatric condition on the RAI-HC predicted appropriate pharmacotherapy. By increasing recognition of psychiatric conditions, the use of standardized, comprehensive assessment instruments in home care may represent an opportunity to improve mental health care in these settings.

Predictors of influenza immunization among home care clients in Ontario.

BACKGROUND: This study examined factors associated with the receipt of influenza vaccination among Ontario home care clients. METHODS: Home care clients were assessed, as part of a routine home visit, during a pilot study of the Resident Assessment Instrument - Home Care (RAI-HC) in 12 Ontario Community Care Access Centres (CCACs). The RAI-HC is a multidimensional assessment that identifies clients' needs and level of functional ability. Multiple logistic regression was used to identify factors associated with influenza immunization in the two years prior to assessment. RESULTS: The overall rate of immunization reached about 80% by 2002. Factors such as age, respiratory problems, diabetes and congestive heart failure were associated with greater uptake, but overall rates of influenza immunization were lower than expected. Low education, smoking and poor medication adherence were negatively associated with influenza immunization. In addition, there was considerable variation in uptake among CCACs after adjusting for other significant individual-level independent variables. INTERPRETATION: Comprehensive assessments like the RAI-HC can be used to help identify and respond to health promotion and disease prevention issues in this population, and to compare rates across Canada.

Risk adjustment methods for Home Care Quality Indicators (HCQIs) based on the minimum data set for home care.

BACKGROUND: There has been increasing interest in enhancing accountability in health care. As such, several methods have been developed to compare the quality of home care services. These comparisons can be problematic if client populations vary across providers and no adjustment is made to account for these differences. The current paper explores the effects of risk adjustment for a set of home care quality indicators (HCQIs) based on the Minimum Data Set for Home Care (MDS-HC). METHODS: A total of 22 home care providers in Ontario and the Winnipeg Regional Health Authority (WRHA) in Manitoba, Canada, gathered data on their clients using the MDS-HC. These assessment data were used to generate HCQIs for each agency and for the two regions. Three types of risk adjustment methods were contrasted: a) client covariates only; b) client covariates plus an "Agency Intake Profile" (AIP) to adjust for ascertainment and selection bias by the agency; and c) client covariates plus the intake Case Mix Index (CMI). RESULTS: The mean age and gender distribution in the two populations was very similar. Across the 19 risk-adjusted HCQIs, Ontario CCACs had a significantly higher AIP adjustment value for eight HCQIs, indicating a greater propensity to trigger on these quality issues on admission. On average, Ontario had unadjusted rates that were 0.3% higher than the WRHA. Following risk adjustment with the AIP covariate, Ontario rates were, on average, 1.5% lower than the WRHA. In the WRHA, individual agencies were likely to experience a decline in their standing, whereby they were more likely to be ranked among the worst performers following risk adjustment. The opposite was true for sites in Ontario. CONCLUSIONS: Risk adjustment is essential when comparing quality of care across providers when home care agencies provide services to populations with different characteristics. While such adjustment had a relatively small effect for the two regions, it did substantially affect the ranking of many individual home care providers.

Home care quality indicators (HCQIs) based on the MDS-HC.

PURPOSE: This study aimed to develop home care quality indicators (HCQIs) to be used by a variety of audiences including consumers, agencies, regulators, and policy makers to support evidence-based decision making related to the quality of home care services. DESIGN AND METHODS: Data from 3,041 Canadian and 11,252 U.S. home care clients assessed with the Minimum Data Set-Home Care (MDS-HC) were used to evaluate a series of indicators suggested by international experts and by focus groups conducted in Canada and the United States. Risk adjustment methods were derived and validated using data from Ontario and Michigan. RESULTS: Of the 73 original candidate HCQIs, 22 were retained for the final list of recommended indicators. All but three indicators include risk adjusters based on individual-level covariates. An agency-level risk adjustment was developed to correct for selection and ascertainment bias. IMPLICATIONS: The HCQIs are new tools providing a first step along the path of quality improvement for home care. These indicators can provide high-quality evidence on performance at the agency level and on a regional basis.
