About

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 Ontario.

Full description

First, investigators will validate health administrative data codes to demonstrate the accuracy of Ontario-wide anesthesia type and regional anesthesia interventions using a reference standard (Ottawa Hospital Data Warehouse data). Then, these validated exposures, in combination with validated outcome measures, will be used to examine the impact of anesthesia interventions on patient and health system outcomes for ambulatory shoulder surgery.
