Questionnaire survey of the frequency of dietary intake during hemodialysis and the impact of COVID-19 in Japan.

Abstract

There have been no coherent reports on the effects of dietary intake during hemodialysis in Japan. Furthermore, few studies have reported the impact of the COVID-19 pandemic on them. This study aimed to investigate dietary intake during hemodialysis and its impact on the spread of COVID-19. This consecutive cross-sectional study included a survey of all hemodialysis facilities in the Niigata Prefecture. The survey form was sent via e-mail or fax. Fifty four facilities (98%) responded to the 2018 survey. Twenty-eight facilities (52%) provided meals, with 18% of all patients undergoing dialysis and 41% of patients undergoing nocturnal dialysis consuming meals during hemodialysis. In the 2020 survey, the number of facilities decreased to 17 (33%), and the number of all patients undergoing dialysis and nocturnal dialysis consuming meals decreased to 13% and 32%, respectively. In the 2022 survey, the number of facilities decreased to 14 (27%), and the number of all patients undergoing dialysis and nocturnal dialysis decreased to 9% and 19%, respectively. The COVID-19 pandemic has caused a decrease in both facilities serving meals and patients' food consumption during hemodialysis. To prevent the loss of meal opportunities, establishing safe methods for food intake and alternatives in hemodialysis facilities is necessary.
