Key result
Higher hospital expenditures in New England were not associated with lower perioperative mortality rates for low- and moderate-risk procedures compared to Manitoba.
Why the study?
Does undergoing surgery in a higher-expenditure region (New England) compared to a lower-expenditure region (Manitoba) reduce postsurgical mortality in patients over 65 years of age?
Population
Residents of New England and Manitoba over 65 years of age undergoing 11 specific surgical procedures
Comparison
Surgical procedures in New England vs Surgical procedures in Manitoba
Design
Cohort
Follow-up

Leslíe L. Roos (1990) conducted a cohort in 11 specific surgical procedures. Surgery in New England vs. Surgery in Manitoba was evaluated on 30-day and 6-month postsurgical mortality. Higher hospital expenditures in New England were not associated with lower perioperative mortality rates for low- and moderate-risk procedures compared to Manitoba.
