Trends in Palliative Care Research During the COVID-19 Pandemic

Abstract

To demonstrate the trends and variety of research on palliative care during the COVID-19 pandemic. A systematic search of the Web of Science database. Since the outbroke of the COVID-19 pandemic, the adjustment of palliative care systems is warranted to maintain a high quality of care. The COVID-19 -related palliative care studies account for approximately 4% of all publications on palliative care. However, there is a dearth of research investigating the nature of these studies. A total of 293 studies were included. Of the included studies, those related to system improvement were the most common (181/293, 61.8%), followed by those related to patient care (79/293, 27.0%), bereavement support for patients or family members (19/293, 6.5%), and the mental health of frontline practitioners (14/293, 4.8%). From these studies, 82, 137, and 74 studies were published in 2020, 2021, and 2022 (until August 1), respectively. The research trends of palliative care demonstrate the flexibility and rapid response of the global palliative care system to the COVID-19 pandemic and show how the palliative care system is evolving. While most studies are interested in system improvement, patient care, and bereavement support, the mental health of frontline practitioners has received less attention. Our findings provide palliative care practitioners with current valuable information and highlight possible future trends.
