Association of the Frequency of In-Home Care Services Utilization and the Probability of In-Home Death.

ABSTRACT:

Importance

The provision of end-of-life care is an important policy issue associated with population aging around the world. Yet it is unclear whether the provision of in-home care services can allow patients the option of in-home death at end of life.

Objective

To assess whether the frequent use of in-home care services can assist recipients to stay at home at the end of life.

Design, setting, and participants

This cohort study of older adults in Japan's long-term care insurance system used national claims data. Participants were long-term care insurance beneficiaries aged 65 years or over who died in 2015, excluding those who died due to external causes such as accidents. Data analyses were conducted from October to December 2020.

Exposures

Mean days of in-home care service used per week from the first day of the month before the month of death to the date of death.

Main outcomes and measures

Primary outcome was whether the older person died at home (or not). To address lack of information on individual preference for place of death, we used an instrumental variable estimation with the full-time equivalent number of care workers providing in-home care services per older population at the municipality level in 2014.

Results

Of the 572 059 decedents included in the study, 314 743 (55.0%) were women (median [IQR] age, 87 [81-91] years). The proportion of in-home deaths was 10.5% (60 175 decedents), and 81 675 decedents (14.3%) used in-home care services at least once prior to their death. Ordinary least squares and 2-stage least squares analyses both indicated that more frequent use of in-home care was associated with a higher probability of in-home deaths (ordinary least squares estimate, 5.0 percentage points; 95% CI, 4.9-5.1 points vs 2-stage least squares estimate, 3.6 percentage points; 95% CI, 2.3-4.9 points).

Conclusions and relevance

This retrospective cohort study using an instrumental variable approach demonstrated that more frequent use of in-home care services at the end of life was associated with a higher probability of in-home death. One policy implication of these results is that in order to meet the end-of-life preferences of patients, it is not only necessary to promote the provision of medical services at home but also to ensure an adequate supply of care workers.

Project description:Publicly funded home care in Canada supports older adults in the community to delay institutional care, which results in complex care populations with multimorbidity that includes mental health problems. The purpose of this study is to examine prevalence of psychiatric diagnoses and other mental health symptoms among older clients in two publicly funded Home Care (HC) Programs and their psychiatry service utilization (psychiatrist visits) after being admitted to home care. This retrospective cohort study examines clients age 60 years and older in the two Canadian provinces of Manitoba (MB), specifically the Winnipeg Regional Health Authority (WRHA) (n = 5,278), and Nova Scotia (NS) (n = 5,323). Clients were admitted between 2011 and 2013 and followed up to 4 years. Linked data sources include the InterRAI Resident Assessment Instrument for Home Care (RAI-HC), physician visit/billing data and hospital admission data. Both regions had similar proportions (53%) of home care clients with one or more psychiatric diagnoses. However, we observed over 10 times the volume of psychiatry visits in the WRHA cohort (8,246 visits vs. 792 visits in NS); this translated into a 4-fold increased likelihood of receiving psychiatry visits (17.2% of WRHA clients vs. 4.2% of NS clients) and 2.5 times more visits on average per client (9.1 avg. visits in MB vs. 3.6 avg. visits in NS). The location of psychiatry services varied, with a greater number of psychiatry visits occurring while in hospital for WRHA HC clients compared to more visits in the community for NS HC clients. Younger age, psychotropic medication use, depressive symptoms, dementia, and having an unstable health condition were significantly associated with receipt of psychiatry visits in both cohorts. Access to psychiatric care differed between the cohorts despite little to no difference in need. We conclude that many home care clients who could have benefitted from psychiatrist visits did not receive them. This is particularly true for rural areas of NS. By linking the RAI-HC with other health data, our study raises important questions about differential access to psychiatry services by site of care (hospital vs. community), by geographical location (MB vs. NS and urban vs. rural) and by age. This has implications for staff training and mental health resources in home care to properly support the mental health needs of clients in care. Study results suggest the need for a mental health strategy within public home care services.

Project description:While home is frequently expressed as the favorite place of death (PoD) among terminally ill cancer patients, various factors affect the fulfillment of this wish. The determinants of the PoD of cancer patients in countries without healthcare system-integrated palliative and supportive care have not been studied before. This study aimed at identifying the predictors of the PoD of patients who suffer from advanced cancer by developing a reliable predictive model among who received home-based palliative care in Iran as a representative of the countries with isolated provision of palliative care services. In a cross-sectional study, electronic records of 4083 advanced cancer patients enrolled in the Iranian Cancer Control Center (MACSA) palliative homecare program, who died between February 2018 and February 2020 were retrieved. Multivariable binary logistic regression analysis as well as subgroup analyses (location, sex, marital status, and tumor topography) was performed to identify the predictors of PoD. Of the 2398 cases included (mean age (SD) = 64.17 (14.45) year, 1269 (%52.9) male), 1216 (50.7%) patients died at home. Older age, presence and intensity of medical homecare in the last two weeks and registration in the Tehran site of the program were associated with dying at home (P < 0.05). Gynecological or hematological cancers, presence and intensity of the calls received from the remote palliative care unit in the last two weeks were predictors of death at the hospital (p < 0.05). The model was internally and externally validated (AUC = 0.723 (95% CI = 0.702-0.745; P < 0.001) and AUC = 0.697 (95% CI = 0.631-0.763; P < 0.001) respectively). Our model highlights the demographic, illness-related and environmental determinants of the PoD in communities with patchy provision of palliative care. It also urges policymakers and service providers to identify and take the local determinant of the place of death into account to match the goals of palliative and supportive services with the patient preferences.
