Objective:To construct and implement a multidisciplinary pain management model during the perioperative period based on the project-achieving quality control circle, so as to improve the quality of patient pain management during the perioperative period.Methods:Using the convenient sampling, 310 surgical patients from the Department of Gastrointestinal Surgery, Hepatobiliary Surgery, Thoracic Surgery, Urology Surgery and Joint Surgery of Liaocheng People's Hospital from June to July 2020 were taken as the pre-improvement group, and the routine perioperative pain management model was implemented. Starting from August 2020, a project-achieving quality control circle was carried out, following the steps of theme selection, topic clarification, goal setting, formulation of strategies, investigation of the best strategies, implementation of strategies, and confirmation of effectiveness, to implement a multidisciplinary pain management model during the perioperative period. A total of 310 surgical patients admitted to 5 departments from February to March 2021 were included in the improvement group.Results:The implementation rate of multidisciplinary pain management plan, the rate of out-of-bed activity within 24 hours after surgery, the rate of excellent postoperative rehabilitation compliance, and the average sleep score of patients in the improvement group all increased, with statistical differences ( P<0.05). After improvement, the awareness rate of pain knowledge among medical and nursing staff, the accuracy rate of nurses' rest and active pain assessment records, and the score of nurse pain knowledge all increased, and the differences were statistically significant ( P<0.05) . Conclusions:The construction and implementation of a multidisciplinary pain management model during the perioperative period based on the project-achieving quality control circle can effectively improve the quality of pain management for surgical patients, accelerate patient recovery, and improve the pain management of medical and nursing staff.
