About this study

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Ontario residents
  • Aged 18 years and older
  • Elective ambulatory shoulder surgery performed in Ontario between April 2009 and December 2016.

Exclusion criteria

  • Emergency Surgery
  • If a patient undergoes multiple elective shoulder surgeries within the time period, only the first surgery will be included for any participant in the study period.

Primary outcomes

  1. Postoperative Death, Admission, Readmission or Emergency Department Visits

    Time frame: Date of surgery to 7 days (ED visits) and 30 days (readmissions) after surgery or death date, whichever came first

    Composite outcome of: 1) unplanned admissions on the day of surgery , 2) post-discharge emergency department visits within 7 days of surgery, 3) readmission within 30 days of surgery, and 4) death from any cause

Secondary outcomes

  1. Health System Costs

    Time frame: Date of surgery to 7 days and 30 days after surgery or death date, whichever came first

    Costs in Canadian dollars will be calculated using standardized patient-level costing algorithms.

  2. Neurology Consultations or Diagnostics

    Time frame: Date of surgery to 90 days after surgery or death date, whichever came first

    Occurrence of neurology consult and/or nerve conduction study
