Objective To explore the effectiveness of WeChat-based multidisciplinary team-driven continuity of rehabilitation services on scar outcome and recovery of hand function in hand burns patients, and to promote recovery of patients. Methods Eighty-eight patients with deep second- or third-degree hand burns were assigned to a control group or an observation group chronologically, with 44 cases in each group, receiving either conventional or WeChat-based multidisciplinary team-driven continuity of rehabilitation services. Intervention effect was measured when wound healing was achieved and at 4, 12, and 24 weeks post-healing using the Vancouver Scar Scale (VSS), Total Active Movement (TAM) of the finger, and the Carroll Upper Extremity Function Test (UEFT). Results Forty patients in both groups completed the study. At 4, 12, and 24 weeks post-healing, the observation group demonstrated significantly lower scar scores, greater TAM, and higher UEFT scores compared to the control group (all P<0.05). Conclusion WeChat-based multidisciplinary team-driven continuity of rehabilitation services can improve scar outcome, hand and upper extremity function of hand burns patients.
