(P20-042-20) Development of a Personalized Apps to Inculcate Dietary Self-Management for Maintenance Hemodialysis Patients: A Need Analysis

Objectives: Dietary non-adherence is highly prevalent among maintenance hemodialysis (HD) patients resulting in multitudes health complications and poor treatment outcomes. Given high penetration of smartphone, well-designed mobile health apps emerged as a potential tool to empower HD patients with dietary self-management skills. This need analysis study determined the perception and expectation of patients and dietitians on the features and the use of apps in dialysis care to foster development of evidence-based renal diet apps.

Methods: This was a mixed-method study with concurrent triangulation design. The quantitative arm involved HD patients (n=184) through face-to-face interview and dietitians (n=120) via anonymous online survey. While the qualitative arm consisted of 10 in-depth interviews (HD patients) and 8 email interviews (dietitians). Descriptive and thematic analyses were used, and the results were compared.

Results: A total of 69.6% of HD patients owned a smartphone. More than half (53.9%) of the smartphone users had the experience of searching health information especially nutrition-related topics (91.3%). Majority of them (78.9%) perceived renal diet apps as very important and were willing to use (80.5%). They agreed that renal diet apps can help them in preventing nutrition complications (82.0%), planning menu (78.9%) and monitoring nutrient intakes (82.8%).  In the context of practising dietitians, 60.8%  aware of the existence of renal diet apps but only 38.3% of them would recommend existing renal diet apps to their patients due to lack of local content (42.5%) and unsure credibility (37.5%). Most of them (88.3%) perceived that local-based renal diet app is needed and agreed that it can enhance dietetics care in HD population (90.8%). Top features anticipated by both patients and dietitians included plan or order, tailored assistance, usability and tracker.

Conclusions: Dietary self-management via mobile health apps seems to be feasible in the dialysis population given the high smartphone penetration, strong desire to use and positive perceptions from patients and dietitians. Features valued by patients and dietitians will be integrated into the design of the apps to promote acceptance and usage.
