Overall survival of homebound patients without cancer receiving inpatient respite care in a hospital ward in Japan: a retrospective observational study

Abstract

Objectives This study aimed to investigate the relationship between the use of inpatient respite care and the overall survival of homebound patients without cancer admitted to a hospital ward in order to assess the potential impact of inpatient respite care on the duration of home care.Design This was a single-centre, hospital ward-based retrospective observational study.Setting and participants From March 2011 to September 2018, 393 cancer-free older patients (median age, 84.0 years; 53.9% women) receiving continuous medical care at home through clinics were enrolled upon admission to a hospital ward.Primary outcome measures Continuous cumulative survival curves were generated using the Kaplan-Meier method for two groups: inpatient respite care users and non-users. Additionally, prognostic factors associated with all-cause mortality were assessed using the Cox proportional hazards model.Results The Kaplan-Meier curves for inpatient respite care users without cancer admitted to the hospital ward demonstrated a longer median survival time than non-users. Subgroup analyses for patients with or without neurological disorders yielded similar results. The HR for inpatient respite care use, after adjusting for age, sex and other confounding variables, was 0.480 (95% CI: 0.328 to 0.703, p<0.001).Conclusions Homebound patients without cancer receiving inpatient respite care during the study period in Japan demonstrated higher overall survival than those who did not receive respite care. Subgroup analysis of patients with neurological disorders yielded similar results. Further studies are needed to investigate the benefits of inpatient respite care, including the exploration of appropriate methods for its use.
