Research objective: 

Project Objectives:

1) Research Questions in Part 1:

Policy Question: What impacts on surgical outcomes resulted from 24 hospitals in BC participating in NSQIP?

Answers will be formulated in terms of "Adjusted differences: Differences among hospitals' differences over time".

Primary analysis = Infection rates: Differences between a) differences of infection rates before versus after hospitals participated in NSQIP, compared with b) differences of infections rates between the same time windows in nonparticipating hospitals.

Secondary analysis = Other outcomes: Differences between a) differences of other outcomes before versus after hospitals participated in NSQIP, compared with b) differences of those outcomes between the same time windows in nonparticipating hospitals.

Tertiary analysis = Costs: Differences between a) differences of costs before versus after hospitals participated in NSQIP, compared with b) differences of those costs between the same time windows in nonparticipating hospitals.

2) Hypothesis:

i) Measurement and reporting of surgery outcomes using NSQIP protocols has reduced adverse outcomes of surgery in BC, as measured by Ministry of Health administrative databases;

ii) Specifically, incidence rates of infections, readmissions and deaths in NSQIP hospitals in BC were lower after compared with before participation in NSQIP, after adjustment for the background trend in rates among non-NSQIP hospitals.

iii) Estimated costs associated with these reductions exceed $5M per year.

    change the title to “Quick and Cheap…” so we presented it with the original title as below)
