RESUMEN

The complexity and heterogeneity of patients with multimorbidity and polypharmacy renders traditional disease-oriented guidelines often inadequate and complicates clinical decision making. To address this challenge, guidelines have been developed on multimorbidity or polypharmacy. To systematically analyse their recommendations, we conducted a systematic guideline review using the Ariadne principles for managing multimorbidity as analytical framework. The information synthesis included a multistep consensus process involving 18 multidisciplinary experts from seven countries. We included eight guidelines (four each on multimorbidity and polypharmacy) and extracted about 250 recommendations. The guideline addressed (i) the identification of the target population (risk factors); (ii) the assessment of interacting conditions and treatments: medical history, clinical and psychosocial assessment including physiological status and frailty, reviews of medication and encounters with healthcare providers highlighting informational continuity; (iii) the need to incorporate patient preferences and goal setting: eliciting preferences and expectations, the process of shared decision making in relation to treatment options and the level of involvement of patients and carers; (iv) individualized management: guiding principles on optimization of treatment benefits over possible harms, treatment communication and the information content of medication/care plans; (v) monitoring and follow-up: strategies in care planning, self-management and medication-related aspects, communication with patients including safety instructions and adherence, coordination of care regarding referral and discharge management, medication appropriateness and safety concerns. The spectrum of clinical and self-management issues varied from guiding principles to specific recommendations and tools providing actionable support. The limited availability of reliable risk prediction models, feasible interventions of proven effectiveness and decision aids, and limited consensus on appropriate outcomes of care highlight major research deficits. An integrated approach to both multimorbidity and polypharmacy should be considered in future guidelines.

RESUMEN

Calculating the longitudinal extension of the average attributable fraction (LE-AAF) for many risk factors (RFs) requires a two-stage computational process using only those combinations of RFs observed in the dataset. We first screen candidates RFs in a Cox Model, and assuming piecewise constant hazards, use pooled logistic regression to model the probability of death as a function of combinations of selected RFs. We average the iterative differencing of the attributable fractions calculated for all overlapping subsets of co-occurring RFs to obtain a LE-AAF for each RF that is additive and symmetrical. We illustrate by partitioning the additive proportions of death from 10 different groupings of acute and chronic diseases, on a national sample of older persons from the US (Medicare Beneficiary Survey) over a 4-year period and compare with results reported by the National Center for Healthcare Statistics. We conclude that careful screening of RFs with analysis restricted to extant combinations greatly reduces computational burden. LE-AAF accounted for a cumulative total of 66% of the deaths in our sample, compared with the 83% accounted for by the National Center for Healthcare Statistics.

RESUMEN

BACKGROUND AND OBJECTIVE: Evidence-based second stage translational studies are necessary and difficult to evaluate. A quasi-experimental design is used to compare the rate of fall-related health care utilization of two geographically disparate areas in Connecticut, a small state in the northeastern United States, to evaluate an intervention designed to reduce fall-related injuries among older persons. This evaluation examines the two years immediately prior to intervention. METHODS: The experimental units are postal (i.e., zip) code tabulation areas (ZCTAs) in which counts of fall-related health care utilization and demographic characteristics can be gathered from local and federal public health sources. We employ hierarchical modeling to determine whether there was a difference in fall-related health care utilization between the study arms prior to initiating the intervention. Geographic information systems are used to characterize neighboring ZCTAs and to graph model-adjusted rates of fall-related utilization. RESULTS: After adjustment for covariates and spatial variation, we observed no significant difference between rates or temporal trends of fall-related health care utilization in the study arms over the two year pre-intervention period. CONCLUSION: The study arms of the Connecticut Collaboration for Falls Prevention have equivalent rates and temporal trends of fall-related utilization over the two year pre-intervention period.

RESUMEN

BACKGROUND: The rapidly expanding proportion of the US population 65 years and older is anticipated to have a profound effect on health care expenditures. Whether the changing health status of older Americans will modulate this effect is not well understood. This study sought to determine the relationship between functional status and government-reimbursed health care services in older persons. METHODS: Longitudinal cohort study of a representative sample of community-dwelling persons 72 years or older. Clinical data were linked with data on 2-year expenditures for Medicare-reimbursed hospital, outpatient, and home care services and Medicare- and Medicaid-reimbursed nursing home services. Per capita expenditures associated with different functional status transitions were calculated, as were excess expenditures associated with functional disability adjusted for demographic, health, and psychosocial variables. RESULTS: The 19.6% of older persons who had stable functional dependence or who declined to dependence accounted for almost half (46.3%) of total expenditures. Persons in these groups had an excess of approximately $10 000 in expenditures in 2 years compared with those who remained independent. The 9.6% of patients who were dependent at baseline accounted for more than 40.0% of home health and nursing home expenditures; the 10.0% who declined accounted for more than 20.0% of hospital, outpatient, and nursing home expenditures. CONCLUSIONS: Functional dependence places a large burden on government-funded health care services. Whereas functional decline places this burden on short- and long-term care services, stable functional dependence places the burden predominantly on long-term care services. Declining rates of functional disability and interventions to prevent disability hold promise for ameliorating this burden.

RESUMEN

PURPOSE: The increasing demand for geriatric home-based care makes it timely to examine how the existing system can become most effective and efficient in promoting the functional outcomes of older patients. DESIGN AND METHODS: A multidisciplinary work group identified home care agency policies, misconceptions of older adults and their caregivers, and practice patterns of nurses, therapists, and home health aides that can impede patients' progress toward functional independence. This article describes the process that one home care agency used to remove these obstacles. RESULTS AND IMPLICATIONS: The work group developed and implemented a restorative model of care that integrates the medical treatments for acute disease processes and the personal care and rehabilitative interventions directed toward chronic disabilities, to improve the functional outcomes of older adults receiving home care.

RESUMEN

OBJECTIVE: While dizziness has traditionally been considered solely as a symptom of discrete diseases, recent findings from population-based studies of older persons suggest that it may often be a geriatric syndrome with multiple predisposing risk factors, representing impairments in diverse systems. To validate these findings, we identified predisposing risk factors for dizziness in a clinic-based population. DESIGN: Cross-sectional study. SETTING: Geriatric assessment center. PARTICIPANTS: 262 consecutive, eligible patients. MEASUREMENTS: Medical history and physical examination data were ascertained and characteristics of patients with and without a report of dizziness were compared. RESULTS: Seven factors were independently associated with a report of dizziness, namely depressive symptoms, cataracts, abnormal balance or gait, postural hypotension, diabetes, past myocardial infarction, and the use of three or more medications. Of patients with none of these risk factors, none reported dizziness. This proportion rose from 6% among patients with one factor, to 12%, 26%, and 51% among patients with two, three, and four or more factors, respectively. CONCLUSIONS: The finding of similar factors associated with dizziness in previous community-based cohorts and the present clinic-based cohort supports the possibility of a multifactorial etiology of dizziness in many older persons. A multifactorial intervention targeting the factors identified in these studies may be effective at reducing the frequency or severity of dizziness in older patients.

RESUMEN

OBJECTIVE: The recommended clinical strategy for a health condition should depend both on the known causes of and outcomes associated with the condition. The aim of this study was to determine the range of adverse outcomes associated with chronic dizziness. DESIGN: Population-based prospective cohort study. SETTING AND PARTICIPANTS: A probability sample of 1087 persons, age 72 and older, living in the community. MEASUREMENTS: The following were measured: chronic dizziness, death, hospitalizations, falls, syncope, basic and instrumental activities of daily living, depressive symptoms, self-rated health, falls self-efficacy, and social activities. RESULTS: Of the 1087 participants, 261 (24%) reported chronic dizziness. Over 1 year of follow-up, chronic dizziness was not associated with mortality, hospitalization for any reason, or change in basic or instrumental activities of daily living, but was associated with risk of falling (unadjusted relative risk [RR] 1.35; 95% confidence interval [CI] 1.06-1.72) and with experiencing syncope (RR 2.31; 95% CI 1.24-4.30). After adjustment for baseline level, chronic dizziness also was associated with worsening of depressive symptoms, self-rated health, falls efficacy, and social activities. The relationship remained significant, after adjustment for potential confounding factors, for self-rated health (T-statistic -2.95, P = .003) and falls efficacy (T-statistic -2.68; P = .008), and was of marginal significance for depressive symptoms (T-statistic -1.73; P = .085). CONCLUSIONS: These results suggest that the goals of care for older persons with chronic dizziness should be redirected from solely identifying and treating discrete diseases--an often expensive and unrewarding task--toward reducing the symptoms of chronic dizziness and alleviating the resulting physical, psychological, and social disability.

RESUMEN

BACKGROUND: Although the home is expanding as a potential site for acute illness treatment, little is known about patients' preferences for home vs the hospital. OBJECTIVE: To determine older persons' preferences for home or hospital as a treatment site for acute illness and factors associated with preference. METHODS: Two hundred forty-six community-dwelling persons aged 65 years or older hospitalized with congestive heart failure, chronic obstructive pulmonary disease, or pneumonia were identified in 2 urban teaching hospitals and received telephone interviews 2 months after hospitalization. They were asked their preference for home or hospital treatment, given the availability of equivalent therapies and outcomes at the 2 sites and a nursing visit and several hours of home health aide assistance daily in the home. They were also asked about changes in preference with changes in the description of the outcome or the availability of services. RESULTS: If home and hospital offered equivalent outcomes, 46% of the sample preferred treatment at home. Preferences were heavily dependent on the outcome of the illness, physician opinion about the best site of care, and the provision of house calls. Higher education, white race, living with a spouse, being deeply religious, and having 2 or more dependencies in activities of daily living were associated with a preference for home treatment. CONCLUSIONS: Under conditions of equivalent outcome, preferences for treatment site are almost equally divided between home and hospital. Explicit elucidation of preferences is necessary if patients' preferences are to play a meaningful role in decision making about site of care.

RESUMEN

BACKGROUND: In previous studies of dizziness, the prevalence of specific causes has varied widely and either no or multiple causes have been identified. Dizziness might be better considered a geriatric syndrome that results from impairment or disease in multiple systems. OBJECTIVE: To determine the predisposing characteristics and situational factors associated with dizziness. DESIGN: Population-based, cross-sectional study. SETTING: Community. PARTICIPANTS: Probability sample of 1087 community-living persons in New Haven, Connecticut, who were at least 72 years of age. MEASUREMENTS: Episodes of dizziness that occurred for at least 1 month; manifestations of dizziness; and predisposing demographic, medical, neurologic, sensory, and psychological characteristics. RESULTS: 261 participants (24%) reported dizziness; 56% of dizzy persons described several sensations and 74% reported several triggering activities. The adjusted relative risks for characteristics associated with dizziness were 1.69 (95% CI, 1.24 to 2.30) for anxiety, 1.36 (CI, 1.02 to 1.80) for depressive symptoms, 1.27 (CI, 0.99 to 1.63) for impaired hearing, 1.30 (CI, 1.01 to 1.68) for five or more medications, 1.31 (CI, 0.92 to 1.87) for postural hypotension, 1.34 (CI, 0.95 to 1.90) for impaired balance, and 1.31 (CI, 1.00 to 1.71) for past myocardial infarction. The adjusted relative risk for dizziness was 1.38 (CI, 1.27 to 1.49) for each additional characteristic. CONCLUSIONS: The association among characteristics in multiple domains (cardiovascular, neurologic, sensory, psychological, and medication-related) and dizziness, coupled with the multiplicity of sensations and triggering activities, suggests that dizziness may be a geriatric syndrome, similar to delirium and falling. If so, an impairment reduction strategy, proven effective for other geriatric syndromes, may be effective in reducing the symptoms and disabilities associated with dizziness.

RESUMEN

The objective of this study was to determine if increased alcohol exposure is associated with greater use of health services among older veterans. A total of 129 older veterans (> or =65 years old), receiving longitudinal care in a Veterans' Administration primary care clinic, were followed retrospectively for up to 42 months. Subjects were screened at baseline for problem drinking with the CAGE or the quantity-frequency questions from the Alcohol Use Disorders Identification Test (QF-AUDIT), and stratified by exposure into three categories: abstainers, social drinkers, and problem drinkers. Outcomes included total outpatient clinic visits, laboratory tests, radiologic and other technologic procedures, as well as acute care hospitalizations. For all subjects (N = 129), no association was found between alcohol exposure and use of any outpatient services. Among CAGE-screened (n = 62) abstainers, social drinkers, and problem drinkers, significant differences were found in the median number of laboratory tests (7.3 vs. 3.4 vs. 7.1, P = 0.004) and hospitalizations (0.3 vs. 0.0 vs. 0.3, P = 0.001) per patient year of follow-up. No exposure-outcome associations were present, however, among QF-AUDIT-screened subjects (n = 67). We were unable to demonstrate a consistent relationship between alcohol exposure and health services utilization. The effects of alcohol on older veterans' use of health services varied with the method used to measure alcohol exposure. Additional studies are needed to determine whether multiple, or possibly new, measures can more precisely define the health effects of alcohol in older populations.

RESUMEN

BACKGROUND: Identifying and eliminating environmental hazards in the home has high face validity but little empirical support for fall prevention. OBJECTIVE: The objective of this study was to determine whether environmental hazards increase the risk of nonsyncopal falls in the homes of community-living older persons. RESEARCH DESIGN: This was a prospective cohort study. PARTICIPANTS: The study included 1,088 men and women from a probability sample of 1,103 persons > or =72 years of age. MEASURES: A room-by-room assessment for 13 potential trip or slip hazards was completed at baseline and 1 year later by a trained research nurse using a standard instrument. Falls were ascertained monthly for 3 years using a fall calendar and follow-up phone calls. RESULTS: The numbers of participants with a nonsyncopal fall (by room) were as follows: 88 (kitchen), 144 (living room), 41 (hallway), 136 (bedroom), and 59 (bathroom). The risk of a nonsyncopal fall was significantly elevated for only 1 of the 13 trip or slip hazards. For exposure to > or =1 hazards per room, the relative risks adjusted for age, gender, and housing type were 0.91 (95% CI, 0.58-1.43) for the kitchen, 1.30 (95% CI, 0.92-1.83) for the living room, 1.73 (95% CI, 0.93-3.22) for the hallway, 1.29 (95% CI, 0.90-1.84) for the bedroom, and 0.57 (95% CI, 0.32-1.00) for the bathroom. No consistent association was found between the 13 trip or slip hazards and nonsyncopal falls, even after participants were categorized by impairments in vision, balance/gait, and cognition. CONCLUSIONS: Our findings do not support an association between environmental hazards and nonsyncopal falls.

RESUMEN

PURPOSE: Home care is increasingly being used as a substitute for hospital care. This study examined older patients' perceptions of the home and of the hospital as treatment sites for acute illness and the patient characteristics that are associated with these perceptions. SUBJECTS AND METHODS: A series of questions derived from open-ended interviews supplemented by literature review were administered by telephone in a cross-sectional, descriptive study to community-dwelling persons age 65 years or older who had been hospitalized 2 months earlier with congestive heart failure, chronic obstructive pulmonary disease, or pneumonia. RESULTS: Among 246 participants, nearly equal proportions agreed with statements that the home and the hospital would be comfortable sites of care (54% versus 55%), that the home and the hospital would provide rapid recovery (41% versus 37%), and that home treatment and hospital treatment would be burdensome on family and friends (40% versus 33%). Although 93% would feel safe in the hospital, only 42% would feel safe at home. Perceptions were not associated with sociodemographic characteristics, primary diagnosis, self-rated health, depression, or social support. Functionally dependent patients had more positive perceptions of treatment at home. CONCLUSIONS: Evaluation of perceptions of home and hospital can facilitate assessing the acceptability of shifting acute care from hospital to home. Our findings suggest that successful expansion of acute home care will require flexibility in the use of home and hospital as well as education to change perceptions about the safety and efficacy of treatment at home.

RESUMEN

OBJECTIVE: To determine whether a home-based systematic multicomponent rehabilitation strategy leads to improved outcomes relative to usual care. DESIGN: A randomized controlled trial with 12 months of follow-up. SETTING: General community; 27 home care agencies. PARTICIPANTS: Three hundred four nondemented persons at least 65 years of age who underwent surgical repair of a hip fracture at two hospitals in New Haven, CT, and returned home within 100 days. INTERVENTION: Systematic multicomponent rehabilitation strategy addressing both modifiable physical impairments (physical therapy) and activities of daily living (ADL) disabilities (functional therapy) versus usual care. MAIN OUTCOME MEASURES: A battery of self-report and performance-based measures of physical and social function. RESULTS: There was no significant difference in the proportion of participants in the two groups who recovered to prefracture levels in self-care ADL at 6 months (71% vs 75%) or 12 months (74% in both groups) or in home management ADL at 6 months (35% vs 44%) or 12 months (44% vs 48%). There also was no difference between the two groups in social activity levels, two timed mobility tasks, balance, or lower extremity strength at either 6 or 12 months. Compared with participants who received usual care, those in the multicomponent rehabilitation program showed slightly greater upper extremity strength at 6 months (p = .04) and a marginally better gait performance (p = .08). CONCLUSIONS: The systematic multicomponent rehabilitation program was no more effective in promoting recovery than usual home-based rehabilitation. Compared with previous cohorts, however, participants randomized to usual care in our study received more rehabilitative and home care services and experienced a higher rate of recovery. This finding is important given the current pressures to reduce home services. The challenge is to determine the composition and duration of rehabilitation and home services that will ensure optimal functional recovery most efficiently in older persons after hip fracture.

RESUMEN

BACKGROUND: Many older persons who are highly vulnerable do not develop functional dependence, whereas some older persons with low vulnerability do develop functional dependence. We conducted this study to determine the combined effects of baseline vulnerability and precipitating events on the development of functional dependence. METHODS: We analyzed data from two prospective, population-based cohort studies. The development cohort included 799 community-living persons, 72 years of age and older, who were independent in their activities of daily living (ADLs). The validation cohort included 1,051 comparable persons. Participants were classified by baseline vulnerability, defined on the basis of physical performance, cognitive status, and age, and by exposure to potential precipitating events, determined from information gathered from acute care hospital admissions. The primary outcome was the onset of functional dependence, defined as a new disability in one or more of the seven ADLs at the 1-year follow-up interview or admission to a skilled nursing facility prior to the 1-year interview. RESULTS: Functional dependence developed in 109 (13.6%) participants in the development cohort and in 100 (9.3%) participants in the validation cohort. The rates of functional dependence for the low, intermediate, and high vulnerability groups were 7.1%, 17.2%, and 40.1% (p<.001) in the development cohort and 4.8%, 15.0%, and 28.0% (p<.001) in the validation cohort. For the four categories (none, mild, moderate, severe) of precipitating events, the rates of functional dependence were 9.0%, 19.4%, 27.3%, and 53.2% (p<.001 ) in the development cohort and 5.1%, 12.0%, 28.2%, and 53.3% (p<.001) in the validation cohort. For both cohorts, when baseline vulnerability and precipitating events were analyzed in cross-stratified format, the rate of functional dependence increased progressively from low-risk to high-risk groups in all directions (double-gradient phenomenon). The contributions of baseline vulnerability and precipitating events to the development of functional dependence were independent and statistically significant. CONCLUSIONS: Among community-living older persons, baseline vulnerability and precipitating hospital events contribute independently to the development of functional dependence and should each be targeted for intervention when developing strategies aimed at forestalling the onset of functional dependence.

RESUMEN

BACKGROUND: The extent to which alcohol exposure increases risk for functional disability among older adults with cognitive impairment has not previously been assessed. OBJECTIVE: To examine the potential relationship between alcohol use and functional disability among older cognitively impaired adults. DESIGN: Retrospective medical record review. SETTING: Hospital-based geriatric assessment center. PARTICIPANTS: Two hundred forty-two consecutive participants with Mini-Mental Status Examination scores of < or = 24. MEASUREMENTS: Proxy-reported alcohol intake was classified in categories of never, former, light (< 1 drink/week), moderate (> or = 1 but < 14 drinks/week), and heavy (> or = 14 drinks/week) drinkers, and functional status was determined by proxy-reported performance in seven basic (BADL) and seven instrumental (IADL) activities of daily living (0 = poorest function and 14 = best function). RESULTS: Compared with never drinkers, moderate drinkers demonstrated higher mean BADL (12.2 vs 11.4, P = .033) and IADL scores (6.6 vs 5.6, P = .067), whereas heavy drinkers had higher BADL (12.8 vs 11.4, P = .019) but lower IADL scores (4.8 vs 5.6, P = .425). Former drinkers demonstrated both lower BADL (10.8 vs 11.4, P = .107) and IADL scores (3.9 vs 5.6, P = .011) compared with never drinkers. Evaluation of a potential dose-response effect was limited due to low numbers of light and heavy drinkers. CONCLUSIONS: Among cognitively impaired adults, moderate and heavy drinkers demonstrated better BADL function, whereas former drinkers had poorer IADL function, compared with never drinkers. Prospective studies that incorporate additional measures of exposure (e.g., cumulative lifetime consumption) and function (e.g., performance-based tests) may provide a more comprehensive understanding of alcohol's effects among older cognitively impaired adults.

RESUMEN

The process of setting goals for medical care in the context of chronic disease has received little attention in the medical literature, despite the importance of goal-setting in the achievement of desired outcomes. Using qualitative research methods, this paper develops a theory of goal-setting in the care of patients with dementia. The theory posits several propositions. First, goals are generated from embedded values but are distinct from values. Goals vary based on specific circumstances and alternatives whereas values are person-specific and relatively stable in the face of changing circumstances. Second, goals are hierarchical in nature, with complex mappings between general and specific goals. Third, there are a number of factors that modify the goal-setting process, by affecting the generation of goals from values or the translation of general goals to specific goals. Modifying factors related to individuals include their degree of risk-taking, perceived self-efficacy, and acceptance of the disease. Disease factors that modify the goal-setting process include the urgency and irreversibility of the medical condition. Pertinent characteristics of the patient-family-clinician interaction include the level of participation, control, and trust among patients, family members, and clinicians. The research suggests that the goal-setting process in clinical medicine is complex, and the potential for disagreements regarding goals substantial. The nature of the goal-setting process suggests that explicit discussion of goals for care may be necessary to promote effective patient-family-clinician communication and adequate care planning.

RESUMEN

BACKGROUND: Little is known about patients' preferences for site of terminal care. OBJECTIVE: To describe older persons' preferences for home or hospital as the site of terminal care and to explore potential reasons for their preferences. DESIGN: Cross-sectional quantitative and qualitative interviews. SETTING: Participants' homes. PATIENTS: Community-dwelling persons 65 years of age or older who were recently hospitalized with congestive heart failure, chronic obstructive pulmonary disease, or pneumonia and were not selected according to life expectancy; 246 patients participated in quantitative interviews and 29 participated in qualitative interviews. MEASUREMENTS: Preference for site of terminal care and the reasons for that preference. RESULTS: In quantitative interviews, 118 patients (48%) preferred terminal care in the hospital, 106 (43%) preferred home, and 22 (9%) did not know. One third changed their preference when asked about their preference in the event of a nonterminal illness. Reasons for preference identified during qualitative interviews included the desire to be with family members and concerns about burden to family members and their ability to provide necessary care. Concern about long-term care needs resulted in preference for a nursing home when choice was not constrained to home and hospital. CONCLUSIONS: Preference for home as the site of care for terminal illness exceeds existing practice. However, the current debate about home versus hospital as the ideal site for end-of-life care may ignore an important issue to older persons--namely, the care of disabilities that precede death.

RESUMEN

OBJECTIVES: This study sought to estimate the population-based prevalence of environmental hazards in the homes of older persons and to determine whether the prevalence of these hazards differs by housing type or by level of disability in terms of activities of daily living (ADLs). METHODS: An environmental assessment was completed in the homes of 1000 persons 72 years and older. Weighted prevalence rates were calculated for each of the potential hazards and subsequently compared among subgroups of participants characterized by housing type and level of ADL disability. RESULTS: Overall, the prevalence of most environmental hazards was high. Two or more hazards were found in 59% of bathrooms and in 23% to 42% of the other rooms. Nearly all homes had at least 2 potential hazards. Although age-restricted housing was less hazardous than community housing, older persons who were disabled were no less likely to be exposed to environmental hazards than older persons who were nondisabled. CONCLUSIONS: Environmental hazards are common in the homes of community-living older persons.

RESUMEN

OBJECTIVE: To determine characteristics associated with site of death in a cohort of long-term homecare patients. DESIGN: Cohort study. SETTING: Community-based long-term care program. SUBJECTS: All patients 65 years of age or older who died within 1 year of admission during 1989 and 1990. MAIN OUTCOME MEASURE: Site of death. RESULTS: Of 620 subjects, site of death was hospital for 302 (49%), home for 132 (21%), nursing home for 124 (20%), and inpatient hospice for 45 (7%). Among patients living at home before death, factors associated with dying at home rather than in a hospital or inpatient hospice included female gender (relative risk (RR) 1.40, 95% confidence interval (CI) 1.00, 1.90); severely dependent functional status (RR 2.38, CI 1.39, 4.17) and cognitive status (RR 1.51, CI 1.10, 2.06); and dying of cancer (RR 1.68, CI 1.11, 2.55), chronic lung disease (AOR 1.75, CI 1.04, 2.95), or coronary artery disease (RR 1.93, CI 1.21, 3.09). Living with a child (RR 1.45, CI .99, 2.11) showed a trend toward association with dying at home. CONCLUSIONS: Even among a subgroup of older persons receiving community-based long-term care, the frequency of home death is low. The finding of an association between functional, social, and disease status and site of death suggests that the relationship between these factors and patients' preferences and care needs must be examined in order to understand how to optimize the site of terminal care.
