Postoperative outcomes among Northern versus Southern Ontario patients undergoing common intermediate- to high-risk elective surgeries: a population-based cohort study.
Purpose: Northern Ontario residents experience multiple health disparities compared with those in Southern Ontario. It is unknown whether this leads to differences in surgical outcomes. We sought to compare postoperative outcomes of patients from Northern and Southern Ontario.
Methods: We conducted a retrospective population-based cohort study using linked administrative health care data to identify all adult patients undergoing selected elective intermediate- to high-risk noncardiac surgeries in Ontario, Canada between 2009 and 2022. The primary outcome was 30-day mortality following surgery. The secondary outcomes were number of days alive at home, hospital length of stay, total health care system costs, discharge disposition, and readmissions. We used regression models to estimate the adjusted association between the exposure and outcomes.
Results: This study identified 562,115 patients, including 41,191 (7.3%) from Northern Ontario. We did not find strong evidence that mortality rates were higher for Northern vs Southern Ontario residents (adjusted odds ratio, 1.04; 95% confidence interval [CI], 0.85 to 1.27). Health system costs were lower for Northern Ontario residents at 30 days [adjusted ratio of mean (RoM), 0.92; 95% CI, 0.89 to 0.96] and at 365 days (adjusted RoM, 0.93; 95% CI, 0.90 to 0.96). Hospital length of stay was longer for Northern Ontario residents (adjusted RoM, 1.06; 95% CI, 1.01 to 1.11). The number of days alive at home and rate of readmission were not statistically different between the two groups.
Conclusion: Northern Ontario residency was not associated with increased odds of mortality after intermediate- to high-risk elective noncardiac surgery. Overall, we found no clinically meaningful differences in postoperative outcomes between patients from Northern and Southern Ontario.

The Canadian Journal of Anesthesia (the Journal) is owned by the Canadian Anesthesiologists’
Society and is published by Springer Science + Business Media, LLM (New York). From the
first year of publication in 1954, the international exposure of the Journal has broadened
considerably, with articles now received from over 50 countries. The Journal is published
monthly, and has an impact Factor (mean journal citation frequency) of 2.127 (in 2012). Article
types consist of invited editorials, reports of original investigations (clinical and basic sciences
articles), case reports/case series, review articles, systematic reviews, accredited continuing
professional development (CPD) modules, and Letters to the Editor. The editorial content,
according to the mission statement, spans the fields of anesthesia, acute and chronic pain,
perioperative medicine and critical care. In addition, the Journal publishes practice guidelines
and standards articles relevant to clinicians. Articles are published either in English or in French,
according to the language of submission.
