Conventional manual visitor screening via intercom systems at the pediatric ward frequently disrupted the workflow of nurses. To address this, we introduced an automated access control system that incorporated facial recognition and body surface temperature monitoring, integrated with the existing intercom system. The guardians of long-term hospitalized children were authorized to use the new system. After implementation, the number of intercom calls significantly decreased from 139 [134, 145] to 120 [96, 129] (p=0.004).
