Clinical effects of a home care program for patients with peritoneal dialysis in a tertiary care hospital.

ABSTRACT

Background: Digital health technologies have been rapidly adopted during the coronavirus disease 2019 pandemic. In Korea, a home care program, including face-to-face educational consultation and remote patient monitoring, was initiated to improve patients' quality of life. This study focused on patients with end-stage renal disease undergoing peritoneal dialysis to verify the long-term clinical effectiveness of this home care program. Methods: This retrospective cohort study was designed as a pre-post study to analyze the clinical impact of a home care program for patients undergoing peritoneal dialysis in a single tertiary care hospital. A total of 186 patients were selected from June 2017 to May 2022 to identify clinical changes after program implementation by analyzing changes in peritonitis incidence and laboratory test results. Interrupted time series analyses with ordinary least squares linear regression and chi-square tests were used. Results: At baseline, the incidence of peritonitis continuously increased by 0.480 cases per 1,000 patient-months (p = 0.02). After program initiation, the trend significantly decreased by 0.886 cases per 1,000 patient-months (p = 0.02). In addition, the proportion of individuals reaching the clinical target range had increased calcium levels (4.9%p, p = 0.003), stable hemoglobin (1.2%p, p = 0.477), phosphorus (2.8%p, p = 0.09), potassium (-1.6%p, p = 0.22), while parathyroid hormone levels decreased (-6.6%p, p = 0.005). Conclusion: With a reduction in peritonitis incidence and overall improvement in laboratory test results, our study suggests that conducting a home care program for patients undergoing peritoneal dialysis is clinically effective.
