Increase in peritoneal dialysis-related hospitalization rates after telemedicine implementation during the COVID-19 pandemic

To minimize our peritoneal dialysis (PD) population exposure to coronavirus disease (COVID-19), in April 2020 we developed and implemented a telemedicine program. In this investigation, we aimed to compare the hospitalization rates and metabolic disorders in patients undergoing PD 6 months before and after the COVID-19 pandemic and telemedicine implementation.

This single-center retrospective analysis included all active prevalent patients undergoing PD from April 2020. Dialysis records were reviewed to obtain clinical, demographic, laboratory, appointment, and hospitalization data. We compared hospitalization rates (total, non-PD-related, and PD-related), hospitalization-associated factors, and metabolic disorders (hemoglobin, serum potassium, and serum phosphate) 6 months before and after the pandemic.

Our sample comprised 103 participants. During the pre-pandemic and post-pandemic periods, there were 13 and 27 hospital admissions, respectively. The total hospitalization incident rate ratio (IRR) was 2.48 (95% confidence interval [CI], 1.29-4.75). PD-related hospitalizations increased from 3 to 15 episodes (IRR=7.25 [95% CI, 2.11-24.78]). In the pre-pandemic period, the educational level was lower in participants hospitalised due to PD-related issues than in participants not hospitalised. In the post-pandemic period, only sex distribution differed between patients not hospitalised and those hospitalised due to non-PD-related issues. Only serum potassium levels changed significantly in the post-pandemic period (4.79±0.48 vs. 4.93±0.54mg/dL; P<0.01).

This study showed a significant increase in hospitalization rates after the COVID-19 pandemic period and telemedicine implementation, mainly due to PD-related infectious causes. Strategies to improve distance monitoring assistance are needed for the PD population.
