BACKGROUND: Our objective was to evaluate our results after the implementation of lean (the elimination of wasteful parts of a process). METHODS: After meetings with our anesthesiologists, we standardized our "in the operating room-to-skin incision protocols" before pulmonary lobectomy. Patients were divided into consecutive cohorts of 300 lobectomy patients. Several protocols were slowly adopted and outcomes were evaluated. RESULTS: One surgeon performed 2,206 pulmonary lobectomies, of which 84% were for cancer. Protocols for lateral decubitus positioning changed over time. We eliminated axillary rolls, arm boards, and beanbags. Monitoring devices were slowly eliminated. Central catheters decreased from 75% to 0% of patients, epidurals from 84% to 3%, arterial catheters from 93% to 4%, and finally, Foley catheters were reduced from 99% to 11% (p ≤ 0.001 for all). A protocol for the insertion of double-lumen endotracheal tubes was established and times decreased (mean, 14 minutes to 1 minute; p = 0.001). After all changes were made, the time between operating room entry and incision decreased from a mean of 64 minutes to 37 minutes (p < 0.001). Outcomes improved, mortality decreased from 3.2% to 0.26% (p = 0.015), and major morbidity decreased from 15.2% to 5.3% (p = 0.042). CONCLUSIONS: Lean and value stream mapping can be safely applied to the clinical algorithms of high-risk patient care. We demonstrate that elimination of non-value-added steps can safely decrease preincision time without increasing patient risk in patients who undergo pulmonary lobectomy. Selected centers may be able to adopt some of these lean-driven protocols.
