Weekly trends in emergency department visits, hospitalizations, and mortality in patients with end-stage kidney disease: nationwide registry analysis.

ABSTRACT: Patients with end-stage kidney disease (ESKD) undergoing thrice-weekly hemodialysis may experience higher mortality rates following their longest dialysis-free interval. However, information on weekly patterns of emergency department (ED) visits and outcomes in patients with ESKD compared with those without chronic kidney disease (CKD) is limited. We aimed to examine ED visit patterns among patients with ESKD throughout the week in the Republic of Korea and assess whether weekend admissions correlate with higher ED utilization and mortality rates. To this end, we retrospectively analyzed data from the National Emergency Department Information System in the Republic of Korea from January 2018 to December 2021. ED visits, hospitalizations, and in-hospital mortality were assessed daily. Logis
