The present study evaluated end-user experience for effectiveness, efficiency, and satisfaction of a mobile application (app) to estimate the risk of rebound hyperbilirubinemia within 72 hours after initial phototherapy ends for infants at 35 weeks’ gestation or longer and age younger than 14 days. This prospective parallel study was performed at one medical center. The 26 participants are neonatology and pediatric and family physicians, neonatal and family nurse practitioners, and family practice residents, who were asked to estimate the risk of rebound hyperbilirubinemia when phototherapy is stopped for a fictional newborn. Participants in Group 1 (no app) were compared with Group 2 (with app). Satisfaction measured from 1 (0%) to 7 (100%). Group 1 had fewer correct answers than Group 2 (38.5% vs. 84.6%; P = .04). The mean satisfaction score for Group 1 was 2, lower than the score for Group 2, 6.6 (P < .001). This provider-developed app is effective and receives high end-user satisfaction.
