Effects of a remote patient monitoring system for patients on automated peritoneal dialysis: a randomized crossover controlled trial

Purpose: Remote patient monitoring (RPM) has contributed to improved patient-centered outcomes and prognosis in patients with end-stage renal disease on automated peritoneal dialysis (APD). However, evidence from prospective trials is lacking. Methods: The participants (n = 15; median age: 65 years; males: 10; peritoneal dialysis vintage: 6.4 ± 3.5 years) randomly received APD therapy using the Kaguya® APD system either with or without the connective use of the cloud-based RPM software Sharesource® for 12 weeks. The primary outcome was patient satisfaction assessed using a modified nine-item Treatment Satisfaction Questionnaire for Medication (TSQM-9) questionnaire. The secondary outcomes were healthcare resource consumption, the health-related quality of life (HRQOL) subscales assessed with the Kidney Disease Quality of Life-Short Form questionnaire, and clinical laboratory parameters. Results: Significant improvements were observed in the TSQM-9 subscales of Effectiveness (64.4 ± 18.8 vs. 57.8 ± 18.8; P = 0.006) and Convenience (76.3 ± 15.4 vs. 63.3 ± 17.3; P < 0.001) in patients on Sharesource®. Moreover, Sharesource® reduced the total amount of healthcare resource consumption (0.80 ± 1.32 vs. 1.87 ± 2.39 times/12 weeks; P = 0.02) and consultation time during regular monthly visits (813 ± 269 vs. 1024 ± 292 s; P < 0.001). A significant increase in ultrafiltration volume was found associated with more frequent modification of APD prescription in patients with Sharesource®. Sharesource® also improved the HRQOL subscale of General Health and Vitality. Conclusion: Sharesource® can improve patient-centered outcomes in patients on APD while reducing the treatment burden for both patients and medical staff. Trial registration: The study was registered in the Japan Registry of Clinical Trials (jRCT Number: jRCTs032190005).
