Abstract Little is known about the place of death at the regional level in China. Furthermore, the impact of COVID-19 on the place of death remains unclear. We aimed to examine the place of death before and during COVID-19 in Nanchang, China, focusing on changes in home death across different causes, to determine whether these changes were disproportionately experienced among patients with different diseases. Using data from the National Death Registration System, Nanchang, China, this population-based, observational study examined all non-accidental deaths from 1 January 2014 to 31 December 2019 (pre-COVID-19), and 25 January 2020 to 31 December 2022 (during COVID-19). Modified Poisson regression models were employed to assess the association between underlying cause of death and home death, and interaction terms added to evaluate changes over periods. We used R version 4.2.2 for all analyses. The analysis included 198,383 deaths, with a median age of 78 years (IQR: 66–85); 58.2% were male and 41.8% were female. Home deaths rose from 72.7% pre-COVID-19 to 75.6% during COVID-19 (p < 0.0007). Before COVID-19, patients with renal failure (adjusted PR 0.74 [95% CI, 0.67–0.81]), liver disease (0.81 [0.76–0.86]), and hematological cancer (0.88 [0.84–0.92]) were less likely to die at home compared to those with solid cancer. During COVID-19, these disparities diminished, with a significant increase in home deaths among renal failure (1.32 [1.19–1.48]), liver disease (1.19 [1.10–1.29]), and hematological cancer (1.12 [1.05–1.20]). The majority of non-accidental deaths occurred at home, with a notable rise during COVID-19, underscoring the urgent need to strengthen community- and home-based end-of-life care services. Although home death rates for patients with renal failure, liver disease, and hematological cancer were lower before COVID-19, they increased significantly during the pandemic, highlighting disparities in end-of-life care that necessitate targeted improvements.
