A hospital observes that patients receiving a new surgical procedure (n = 100) have 30-day mortality of 8%, while control patients (n = 200) receiving standard surgery have mortality of 12%. However, new procedure patients are healthier: average age 62 vs. 71; 80% have no comorbidities vs. 40%. The hospital plans to use propensity score matching. What would this accomplish?
