Background Children with medical complexity (CMC) are a group of young people who have severe complex chronic conditions, substantial family-identified service needs, functional limitations, and high health care resource use. Technology-enabled hospital-to-home interventions designed to deliver comprehensive in the home setting needed ease CMC family stress, provide proactive this fragile population, avoid hospital admissions, where possible. Objective In usability testing study, we aimed assess areas strength opportunity within DigiComp Kids system, intervention for their families providers. Methods Hospital-based clinicians, members medically children, home-based clinicians participated testing. Participants were recorded tasked think aloud while completing tasks. scored on metrics effectiveness, efficiency, satisfaction, total score was calculated using Single Usability Metric. also provided insights into user experiences during postusability interviews. Results A 15 participants (5 hospital-based 6 members, 4 clinicians) The able complete all assigned tasks independently. Error-free rates ranged from 58% 100%; average satisfaction rating across groups ≥80%, as measured by Ease Question. Task times variable compared task an expert user. Metric scores 80.5% 89.5%. qualitative interviews, stressed need find right fit between needs effort required use system. Interviews revealed that value system its ability create digital bridge home, enabling foster maintain connections boundaries. Conclusions strong groups. Insights gained include importance tailoring implementation match individual streamlining key features, consideration meaning attached allow insight adoption sustainment.
