title: Using lean Six Sigma to improve hospital based outpatient imaging satisfaction.
abstract: Within the hospital based imaging department at Methodist Willowbrook, outpatient, inpatient, and emergency patients are all performed on the same equipment with the same staff. The critical nature of the patient is the deciding factor as to who gets done first and in what order procedures are performed. After an aggressive adoption of Intentional Tools, the imaging department was finally able to move from a two year mean Press Ganey, outpatient satisfaction average score of 91.2 and UHC percentile ranking of 37th to a mean average of 92.1 and corresponding UHC ranking of 60th percentile. It was at the 60th percentile ranking that the department flat lined. Using the Six Sigma DMAIC process, opportunity for further improvement was identified. A two week focus pilot was conducted specifically on areas identified through the Six Sigma process. The department was able to jump to 88th percentile ranking and a mean of 93.7. With pay for performance focusing on outpatient satisfaction and a financial incentive to improving and maintaining the highest scores, it was important to know where the imaging department should apply its financial resources to obtain the greatest impact.
