Survival and characteristics of older adults receiving home-based medical care: A nationwide analysis in Taiwan

Background: In Taiwan, the National Health Insurance Administration initi-ated the integrated home-based medical care (iHBMC) program in 2016 to improve accessibility to health care for homebound patients. This study aimed to describe the characteristics of older people receiving iHBMC services in Taiwan as well as the relationship between patient characteristics and survival.Methods: All older adults registered in the iHBMC application dataset were enrolled between March 1, 2016, and December 31, 2018. Data on social deter-minants of health (income level, residential area), functional status, conscious-ness status, nasogastric tube or urinary catheter placement, and major diseases were retrieved from the database. Data on the frequency of multidisciplinary team members' visits were collected. The survival rate was investigated using the Kaplan-Meier method. A Cox proportional hazards univariate regression was conducted to analyze factors influencing survival rates.Results: A total of 41,079 patients aged >= 65 years were enrolled in iHBMC services. The results showed that the one-year survival rates were 72.1%, 67.4%, and 14.7% in the home-based primary care (HBPC), home-based pri-mary care plus (HBPC-Plus), and home-based palliative care (HBPalC), respec-tively. Nearly two-thirds of the HBPC-Plus patients underwent nasogastric tube placement. The Cox proportional hazards univariate regression analysis showed that a low urbanization level, a low income level, a low functional sta-tus, and an impaired consciousness status were significant predictors of poor survival after adjustment for confounding variables.Conclusions: Older adults receiving iHBMC services had a high mortality rate. The high rate of feeding tube use indicated that education and support for both clinical practitioners and family caregivers regarding careful hand feeding are warranted. There was a relationship between low income levels and poor survival in rural areas. Further research on whether social care could impact prognosis should be considered.
