Summary

This retrospective, population-based cohort study will evaluate the comparative effectiveness of peripheral nerve blocks on patient outcomes after ambulatory shoulder surgery in adults patients undergoing surgery in Ottawa, Ontario.

The investigators will use a coarsened exact matching algorithm prior to the analysis to minimize bias in this observational study. A multivariate logistic regression model will be used to compare the effect of anesthesia interventions on the primary outcome within matched cohorts. Sensitivity analyses will be used to evaluate the robustness of the primary analysis.
