Impact of home visiting nurses on home death proportion in Japan: A nationwide longitudinal ecological study.

Objective: Home visiting nurses contribute to end-of-life home care in an aging society. However, few previous studies reported patient outcomes based on nursing practices. This study aimed to examine the correlation between the number of them and the change in home death proportion.
Methods: We divided the number of home visiting nurses into four categories: absent, shortage, medium, and abundant. This study adopted the interaction term between the nurse categories and year as the major exposure variable, and home death proportion per municipality as the objective variable. We estimated the average marginal effects (AME) as the change in home death proportion from 2015 to 2020.
Results: The total number of home visiting nurses was 36,483 in 2015 and 65,868 in 2020. The coefficients of the interaction term were statistically significant in medium and abundant municipalities (Medium: 1.26 (95% CI: 0.49-2.04), Abundant: 2.15 (95% CI: 0.76-3.55)). Increased home death proportion were estimated as AME: 1.56% (95% CI: 0.99-2.13), 1.35% (95% CI: 0.85-1.84), 2.82% (95% CI: 2.30-3.35), and 3.71% (95% CI: 2.44-4.99) in the absent, shortage, medium, and abundant areas, respectively.
Conclusions: To increase the proportion of home deaths, municipalities require a certain number of home visiting nurses.
