    Background: Family-centered rounds (FCRs) provide many benefits over traditional rounds, including higher patient satisfaction, and shared mental models among staff. These benefits can only be achieved when key members of the care team are present and engaged. We aimed to improve patient engagement and satisfaction with our existing bedside rounds by designing a new FCR process.Methods: We conducted a needs assessment and formed a multidisciplinary FCR committee that identified appointment-based family-centered rounds (aFCRs) as a primary intervention. We designed, implemented, and iteratively refined an aFCR process. We tracked process metrics (rounds attendance by key participants), a balancing metric (time per patient), and outcome metrics (patient satisfaction domains) during the intervention and follow-up periods.Results: After implementing aFCR, 65% of patients reported positive experience with rounds and communication. Rounds duration per patient was similar (9 versus 9.4min). Nurse, subspecialist, and interpreter attendance on rounds was 72%, 60%, and 90%, respectively. We employed a Rounding Coordinator to complete the scheduling and communication required for successful aFCR.Discussion: We successfully improved our rounding processes through the introduction of aFCR with the addition of a rounding coordinator. Our experience demonstrates one method to increase multidisciplinary team member attendance on rounds and patient satisfaction with physician communication in the inpatient setting.
