ABSTRACT
BACKGROUND: There is very little published data on outcomes of COVID-19 among chronic kidney disease (CKD) patients. We compared the outcomes of COVID-19 in a tertiary care renal hospital among CKD V patients on hemodialysis (HD), peritoneal dialysis (PD), and dialysis initiation, in terms of duration of hospitalization, in-patient mortality, and 30-day mortality. METHODS: A total of 436 CKD V patients, on either HD, PD, or dialysis initiation, with COVID-19 who were admitted at the National Kidney and Transplant Institute (NKTI) from March 13, 2020, to August 31, 2020, were included. Kaplan-Meier survival analysis was performed. Comparison of probability of mortality by group was performed using Log-Rank test. p values ≤0.05 were considered statistically significant. RESULTS: Among 436 CKD V patients, 298 (68%) were on HD, 103 (24%) were on PD, and 35 (8%) required dialysis initiation. Overall in-hospital mortality was 34%; 38% were on HD, 20% on PD, and 37% on dialysis initiation. Total 30-day mortality was 27%; 32% were on HD, 26% on PD, and 16% on dialysis initiation. Median follow-up was 24 days. Among the 137 deaths recorded, total median time to death was 10 days; 8.5 days, 15.5 days, and 9 days for HD, PD, and dialysis initiation groups, respectively. Probability of mortality was significantly higher in HD patients versus PD patients (p < 0.00001) and in the dialysis initiation group compared to PD patients (p=0.0234). Mortality probability, however, was not significantly different in HD patients versus the dialysis initiation group (p=0.63). CONCLUSION: Among CKD V patients diagnosed with COVID-19 at the NKTI, those on HD and on dialysis initiation had significantly higher in-hospital and 30-day mortality, compared to patients on PD.
