Implementation and Outcomes of a Standardized Multidisciplinary Treatment Outpatient Model in Two Pediatric Tertiary Hospitals

Objective: This study aims to investigate the implementation and outcomes of the Multidisciplinary Treatment (MDT) outpatient model in two pediatric tertiary hospitals, guided by the standardized "Three Fixed Elements and Four Dedicated Processes" operational plan. Methods: A retrospective analysis was conducted on the MDT outpatient services at the Children's Hospital of Fudan University and Shanghai Children's Hospital, School of Medicine, Shanghai Jiao Tong University, from 2018 to 2025. Results: During the study period, MDT outpatient services at two pediatric hospitals showed substantial growth, serving 15,813 patients with complex and rare conditions. Annual service volume increased from 304 to 5,174, and the number of MDT clinics expanded from 13 to 53, reflecting enhanced service capacity and efficiency. Specialty coverage developed in three phases, incorporating core clinical departments and integrated supportive services. Operational consistency was maintained through a "Three Fixed Elements and Four Dedicated Processes" framework, with performance monitored via a five-dimension management system tracking clinic volume, protocol standardization, expert participation, record quality, and patient satisfaction. Conclusion: The management model effectively enhances multidisciplinary focus, strengthens outpatient clinic construction, and facilitates continuous patient management and successful interdisciplinary collaboration. The study demonstrates the model's success in building a scalable, standardized, and patient-centered MDT system for pediatric complex care.
