Surgeon Factors and Trends Associated With the Use of Subacromial Decompression at the Time of Rotator Cuff Repair.

PURPOSE

Subacromial decompression (SAD) has historically been described as an essential part of the surgical treatment of rotator cuff disorders. However, investigations throughout the 21st century have increasingly questioned the need for routine SAD during rotator cuff repair (RCR). Our purpose was to assess for changes in the incidence of SAD performed during RCR over a 12-year period. In addition, we aimed to characterize surgeon and practice factors associated with SAD use.

METHODS

Records from two large tertiary referral systems in the United States from 2010 to 2021 were reviewed. All cases of RCR with and without SAD were identified. The outcome of interest was the proportion of SAD performed during RCR across years and by surgeon. Surgeon-specific characteristics included institution, fellowship training, surgical volume, academic practice, and years in practice. Yearly trends were assessed using binomial logistic regression modeling, with a random effect accounting for surgeon-specific variability.

RESULTS

During the study period, 37,165 RCR surgeries were performed by 104 surgeons. Of these cases, 71% underwent SAD during RCR. SAD use decreased by 11%. The multivariable model found that surgeons in academic practice, those with lower surgical volume, and those with increasing years in practice were significantly associated with increased odds of performing SAD. Surgeons with fellowship training were significantly more likely to use SAD over time, with the greatest odds of SAD noted for sports medicine surgeons (odds ratio = 3.04).

CONCLUSIONS

Although SAD use during RCR appears to be decreasing, multiple surgeon and practice factors (years in practice, fellowship training, volume, and academic practice) are associated with a change in SAD use.

CLINICAL RELEVANCE

These data suggest that early-career surgeons entering practice are likely driving the trend of declining SAD. Despite evidence suggesting limited clinical benefits, SAD remains commonly performed; future studies should endeavor to determine factors associated with practice changes among surgeons.
