Background:
There is currently no national total shoulder arthroplasty (TSA) database in Canada. As a first step toward a national registry, a regional shoulder database was initiated in 2017. In this study, we describe the implementation of and initial findings from the shoulder database and patient-reported outcomes program.
Methods:
The registry is intended to capture all shoulder arthroplasty procedures in the province of Manitoba and includes surgeon-reported operative details and data on patient-reported outcome measures (PROMs). Every surgeon submits data. We included primary and revision procedures performed since 2017 in the retrospective case series study. We assessed registry coverage by the rate of return of surgeon-completed operative forms and patient-reported outcomes questionnaires, respectively. We determined the incidence of revision by the number of primary procedures linked to a revision within 1 year of surgery.
Results:
A total of 1044 TSA procedures occurred during the study period. Overall, 65.0% were anatomic (n = 679) and 35.0% were reverse TSA procedures (n = 365). Of the 1044 surgeries that took place, the capture rate was 92.0% (n = 960) for operative data. The capture rate for PROM questionnaires was 78.6% preoperatively and 65.8% postoperatively. Four primary procedures were linked with a revision within 1 year of surgery (0.4%). The most frequent diagnosis reported was degenerative arthritis (n = 558/817). High satisfaction (n = 569/636) and improved joint-specific and general quality-of-life PROMs were reported at 1 year.
Conclusion:
The provincial shoulder database demonstrates the early stages of a registry, which contains useful, granular data and is an opportunity to fill an important gap in Canadian arthroplasty data.
