Regionalization of surgical procedures in New Brunswick
Project Number: P0001

MSSU researchers from three Maritime provinces compared the distribution and organization of treatments for total hip and knee arthroplasty and cardiac surgical procedures across different regions of the province;evaluated how patient outcomes vary within and across jurisdictions and as a function of travel times to the hospital; and evaluated how cost and performance measures vary across hospitals offering these services within the province.

Impacts of doctors' experience on surgical outcomes
Project Number: P0005

Principal Investigator: Philip Leonard

Year Approved: 2015

One of the justifications for closing smaller local hospital facilities in rural New Brunswick in favour of larger regional hospitals is that the quality of surgical outcomes may improve as doctors at larger hospitals perform higher volumes of a given surgery, thus becoming more experienced.

This study examines how patient outcomes vary with surgeon experience level. Is it the overall amount of experience (the total volume of total surgeries conducted) or the number of performances of a specific type of surgery that matters more for patient outcomes? Does the experience level of other doctors working at the same hospital have any impact?
