BACKGROUND: Chronic pain is highly prevalent in US military Veterans, and pain interdisciplinary teams (IDTs) are the gold standard in pain care. There is no standard or guidance for how best to develop and implement pain interdisciplinary teams within complex health care systems. OBJECTIVES: The purpose of this quality improvement project was to evaluate the effectiveness of the standard 9-step Lean 6 Sigma (LSS) methodology in redesigning a pre-existing VA outpatient pain clinic solely offering interventional pain services into an efficient, sustainable pain IDT program. METHODS: The initial evaluation process at a VA Medical Center that primarily serves rural Veterans was redesigned with the a priori goal of developing an efficient, sustainable IDT program that decreased driving days (ie, in-person appointments) required for a comprehensive initial pain evaluation, decreased number of consults required for initial pain evaluations, increased the number of consults to Whole Health services, and increased compliance with policies and standards. Feedback from administrators, clinicians, and Veterans was used to identify inefficiencies then iteratively design, test, and finalize a redesigned service called the PREVAIL Interdisciplinary Team Track (PREVAIL IDT Track). Baseline data was collected for 1 year followed by sustainment data for 14 months. Results were analyzed using descriptive statistics. RESULTS: PREVAIL IDT Track decreased the number of in-person appointments from 5 to 2, decreased consults required for evaluations from 5 to 1, increased the number of unique consults to Whole Health education classes, and made the VA fully compliant with policies and standards. To date, 486 Veterans have participated in the redesigned program, including 167 graduates and 212 current enrollees in this sustained clinical program. CONCLUSION: The success of PREVAIL IDT Track suggests that LSS may be a promising method for redesigning sustainable pain IDTs in VA that improve efficiency.
