Objective To explore the effect of implementing multi-subspecialty-based hierarchical management for perineal wounds. Methods In the historic control design, 33 postnatal women with unhealing vaginal wounds from June 2018 through August 2019 were assigned into the control group, who were given routine treatment for perineal wounds. Another 31 women from September 2019 through January 2021 were assigned into the intervention group, who were given multi-subspecialty-based hierarchical management for perineal wounds. Results The wound healing time was significantly shorter, and the cost of seeking medical treatment (medical expenses, transportation expenses and number of visits) were significantly lower, in the intervention group than those in the control group（P<0.05，P<0.01）. Conclusion Multi-subspecialty-based hierarchical management boosts healing of perineal wounds, decreases the cost of seeking medical treatment, and enhances satisfaction of postnatal women.
