Background: Peritoneal dialysis (PD) affords patients increased independence and improved quality of life. However, the lack of more frequent monitoring may compromise outcomes and decrease wider uptake of this modality. This study uses a novel tablet computer-based interface to allow real-time monitoring and two-way communication to better link PD patients with a dialysis center and care providers.
Methods: A tablet computer with an application that allows enhanced monitoring of all aspects of PD was given to patients to assess their usage in a pilot trial. The interface allows patients to review sterility techniques, enter vital signs and exchange data, upload media such as photos and video clips, synchronize data to be viewed by medical staff, and allow real-time adjustments to the PD prescription. Satisfaction with the interface and comments for enhancement were analyzed using a simple self-administered questionnaire.
Results: Six continuous ambulatory PD patients were enrolled in this pilot study. A total number of 1,172 exchanges were recorded over a period of 251 days. Compliance with the applications ranged from 51 to 92%. No major adverse events were recorded. The overall impression of the interface was 5.2 out of 10. The major criticism was that the application needs to be adjusted depending upon the experience level of the patient and that data entry needs to be simplified and automated.
Conclusion: A tablet computer platform is a feasible concept for continuous ambulatory PD. The major components include flexibility, advanced infrastructure, two-way communication, and real-time interaction. This may encourage more patients to take up PD as their preferred modality of therapy for end-stage renal disease. Modifications to enhance use will be incorporated in subsequent versions.
