ABSTRACT
OBJECTIVE: To evaluate the effect of routine anastomotic leak testing (performed to screen for leaks) vs selective testing (performed to evaluate for a suspected leak in a higher-risk or technically difficult anastomosis) on outcomes in colorectal surgery because the value of provocative testing of colorectal anastomoses as a quality improvement metric has yet to be determined. DESIGN: Observational, prospectively designed cohort study. SETTING: Data from Washington state's Surgical Care and Outcomes Assessment Program (SCOAP). PATIENTS: Patients undergoing elective left-sided colon or rectal resections at 40 SCOAP hospitals from October 1, 2005, to December 31, 2009. INTERVENTIONS: Use of leak testing, distinguishing procedures that were performed at hospitals where leak testing was selective (<90% use) or routine (≥ 90% use) in a given calendar quarter. MAIN OUTCOME MEASURE: Adjusted odds ratio of a composite adverse event (CAE) (unplanned postoperative intervention and/or in-hospital death) at routine testing hospitals. RESULTS: Among 3449 patients (mean [SD] age, 58.8 [14.8] years; 55.0% women), the CAE rate was 5.5%. Provocative leak testing increased (from 56% in the starting quarter to 76% in quarter 16) and overall rates of CAE decreased (from 7.0% in the starting quarter to 4.6% in quarter 16; both P ≤ .01) over time. Among patients at hospitals that performed routine leak testing, we found a reduction of more than 75% in the adjusted risk of CAEs (odds ratio, 0.23; 95% CI, 0.05-0.99). CONCLUSION: Routine leak testing of left-sided colorectal anastomoses appears to be associated with a reduced rate of CAEs within the SCOAP network and meets many of the criteria of a worthwhile quality improvement metric.

There are increasing efforts towards improving the quality and safety of surgical care while decreasing the costs. In Washington state, there has been a regional and unique approach to surgical quality improvement. The development of the Surgical Care and Outcomes Assessment Program (SCOAP) was first described 5 years ago. SCOAP is a peer-to-peer collaborative that engages surgeons to determine the many process of care metrics that go into a "perfect" operation, track on risk adjusted outcomes that are specific to a given operation, and create interventions to correct under performance in both the use of these process measures and outcomes. SCOAP is a thematic departure from report card oriented QI. SCOAP builds off the collaboration and trust of the surgical community and strives for quality improvement by having peers change behaviors of one another. We provide, here, the progress of the SCOAP initiative and highlight its achievements and challenges.
