A Reimbursement System Based on a 48-Hour Target Time for Surgery Shortens the Waiting Time for Hip Fracture Fixation in Elderly Patients

摘要

Objectives: To evaluate whether a pay-for-performance reimbursement system, aimed at expediting surgical fixation of hip fractures in elderly patients, has, in fact, succeeded in shortening the waiting time for surgery. Design: Retrospective analysis of prospectively collected data. Setting: Academic Level II trauma center. Patients/Participants: One hundred fifty patients older than 70 years with femoral neck fractures (OTA/AO 31 A1-A3). Intervention: Implementation of a reimbursement system which incentivizes meeting a 48-hour target time for surgical fixation of hip fractures in elderly patients. Methods: Medical records of 75 consecutive patients operated on 1 year before the implementation of the reimbursement system were compared with records of 75 consecutive patients operated on 1 year after the implementation of the reimbursement system. The collected data included age, sex, American Society of Anesthesiologist score, time from injury to hospital admission, time from admission to surgery, reason for surgical delay beyond 48 hours, perioperative complication rate, and length of postoperative hospitalization. Results: Patients' mean age, sex distribution, American Society of Anesthesiologist score, and time from injury to hospital admission were similar in both groups. The average waiting time for surgery shortened from a mean of 77 hours before implementing the reimbursement system to 28 hours after the implementation (P< 0.001). Before the reimbursement system implementation, 41% of the surgeries were delayed beyond 48 hours due to medical causes, compared with 20% only after the implementation (P< 0.001). Fewer patients developed perioperative complications in the postimplementation group in comparison with the preimplementation group (9% vs. 13%, respectively); however, because the study was not powered to examine differences in complication rate, the significance of this difference remains unclear. Conclusions: A reimbursement system which incentivizes meeting a 48-hour target time for surgery has led to a substantial shortening in the waiting time for surgical fixation of hip fractures in elderly patients in our institution.
