Abstract

Objective To apply Lean Sigma - a quality improvement strategy to eliminate waste and reduce variation and defects - to improve audiology scheduling and utilization in a large tertiary care referral center. The project goals included an increase in utilization rates of audiology block time and a reduction in appointment lead time. Study Design Prospective quality improvement study. Setting Academic tertiary care center. Subjects All patients scheduling audiology clinic visits July 2013 to July 2014. Methods Value stream mapping was performed for the audiology scheduling process, and wasteful steps were identified for elimination. Interventions included a 2-week block release, audiology template revision, and reduction of underutilized blocks. Schedule utilization and lead time for new patient diagnostic audiogram were measured for 5 months postintervention and compared with 5 months preintervention. Overall, 2995 preintervention and 3714 postintervention booked appointments were analyzed. Results Block utilization increased from 77% to 90% after intervention (P
