Evaluation on five-dimensions of a patient counseling mHealth app in ambulatory care pharmacy: A cross-sectional study on pediatric caregiver’s opinion

To improve a pediatric mHealth app for patient counselling, we developed a multi-dimensional evaluation method assessing caregivers' feedback via a cross-sectional survey. Using random questionnaires at a children's hospital outpatient department (967 valid: 478 pre-upgrade, 489 post-upgrade), we evaluated the app across five dimensions (transmission, accuracy, accessibility, completeness, experience). Validity was excellent (I-CVI/S-CVI=1.000), reliability acceptable (ICC 0.806-0.869), with no significant demographic differences between groups (p>0.826). Pre-upgrade, transmission, accuracy, accessibility, and completeness scored >3.50, but experience scored 50 were dissatisfied with completeness. Post-upgrade significantly improved completeness across all ages. The revised app demonstrates excellent accuracy and satisfactory completeness, but requires time for adaptation among caregivers over 50 to transmission/accessibility, and still needs substantial user experience improvements. This multi-dimensional evaluation effectively identified targeted enhancements and ongoing challenges.
