One-Year Medical Utilization and Mortality in Home Health and Nursing Home Care Recipients from Northern Taiwan

OBJECTIVES: Home health care (HHC) and nursing home care (NHC) are mainstays of long-term service in the aged population. Therefore, we aimed to investigate the factors associated with 1-year medical utilization and mortality in HHC and NHC recipients in Northern Taiwan. DESIGN: This study employed a prospective cohort design. SETTING AND PARTICIPANTS: We enrolled 815 HHC and NHC participants who started receiving medical care services from the National Taiwan University Hospital, Beihu Branch between January 2015 and December 2017. METHODS: Multivariate Poisson regression modeling was used to quantify the relationship between care model (HHC vs NHC) and medical utilization. Cox proportional-hazards modeling was used to estimate hazard ratios and factors associated with mortality. RESULTS: Compared with NHC recipients, HHC recipients had higher 1-year utilization of emergency department services [incidence rate ratio (IRR) 2.04, 95% CI 1.16-3.59] and hospital admissions (IRR 1.49, 95% CI 1.14-1.93), as well as longer total hospital length of stay (LOS) (IRR 1.61, 95% CI 1.52-1.71) and LOS per hospital admission (IRR 1.31, 95% CI 1.22-1.41). Living at home or in a nursing home did not affect the 1-year mortality. CONCLUSIONS AND IMPLICATIONS: Compared with NHC recipients, HHC recipients had a higher number of emergency department services and hospital admissions, as well as longer hospital LOS. Policies should be developed to reduce emergency department and hospitalization utilization in HHC recipients.
