Patient and Surgeon Views on Maximum Acceptable Waiting Times for Joint Replacement Point de vue des patients et des chirurgiens sur le temps d’attente maximum acceptable pour le remplacement d’une articulation

Objective: To assess patient and surgeon views on maximum acceptable waiting times (MAWT) for hip and knee replacement, their determinants and their relationship to levels of urgency based on the Western Canada Waiting List Priority Criteria Score (PCS). Methods: At the decision date for surgery, orthopaedic surgeons assessed consecutive patients with the PCS and MAWT. Patients were surveyed 3–12 months post-surgery for MAWT and potential determinants. Results: The patient sample of 208 was 56% female, mean age 69 years (SD 11). Mean MAWT for patients was 18 weeks (SD 11) and for surgeons, 17 weeks (SD 11). Median MAWT for three levels of urgency (PCS) ranged from 13–17 weeks (patients) and 9–26 weeks (surgeons). Patient MAWT was unrelated to the surgeonrated measures: MAWT (r=.05) and the PCS (r=–.10). Multiple regression analysis showed that males, knee vs. hip replacement, a longer waiting time and a perception of fairness in regard to waiting time were significant predictors of longer patient MAWT. Knee replacement, a better ability to walk without significant pain and less potential for progression of the disease were significant predictors of longer surgeon MAWT. Conclusions: Patient and surgeon perspectives on MAWT are important to the development of waiting time benchmarks. Benchmarks based on levels of urgency ensure a more transparent and fair process for waiting time management. Knowledge of determinants of MAWT should inform better management of waiting time and access, by understanding the basis of patient and physician views on acceptable waiting times.
