A Statewide Intervention Improves Appropriate Imaging in Localized Prostate Cancer.

PURPOSE: We implemented a statewide intervention to improve imaging utilization for the staging of patients with newly diagnosed prostate cancer. MATERIALS AND METHODS: MUSIC (Michigan Urological Surgery Improvement Collaborative) is a quality improvement collaborative comprising 42 diverse practices representing approximately 85% of the urologists in Michigan. MUSIC has developed imaging appropriateness criteria (prostate specific antigen greater than 20 ng/ml, Gleason score 7 or higher and clinical stage T3 or higher) which minimize unnecessary imaging with bone scan and computerized tomography. After baseline rates of radiographic staging were established in 2012 and 2013, we used multidimensional interventions to deploy these criteria in 2014. Imaging utilization was then remeasured in 2015 to evaluate for changes in practice patterns. RESULTS: A total of 10,554 newly diagnosed patients with prostate cancer were entered into the MUSIC registry from January 1, 2012 through December 31, 2013 and January 1, 2015 through December 31, 2015. Of these patients 7,442 (79%) and 7,312 (78%) met our criteria to avoid bone scan and computerized tomography imaging, respectively. The use of bone scan imaging when not indicated decreased from 11.0% at baseline to 6.5% after interventions (p <0.0001). The use of computerized tomography when not indicated decreased from 14.7% at baseline to 7.7% after interventions (p <0.0001). Variability among practices decreased substantially after the interventions as well. The use of recommended imaging remained stable during these periods. CONCLUSIONS: An intervention aimed at appropriate use of imaging was associated with decreased use of bone scans and computerized tomography among men at low risk for metastases.

Improvement in clinical TNM staging documentation within a prostate cancer quality improvement collaborative.

OBJECTIVE: To assess the effectiveness of a feedback and educational intervention to increase documentation of clinical tumor-node-metastasis (TNM) stage among urologists in a statewide quality improvement collaborative. METHODS: The Michigan Urological Surgery Improvement Collaborative (MUSIC) is a consortium of urology practices that aims to improve the quality and cost-efficiency of prostate cancer care. In pilot data collection activities, trained abstractors recorded medical record documentation of clinical TNM stage by participating urologists. We compared levels of TNM stage documentation in 12 MUSIC practices at baseline and after performance feedback and a collaborative-wide educational intervention. We examined patient and practice characteristics associated with documentation of TNM stage. RESULTS: We accrued 491 and 581 men with newly diagnosed prostate cancer during the baseline and postfeedback phases of data collection, respectively. At baseline, 58% of patients had clinical TNM staging in the medical record, ranging from 19% to 96% across 12 practices (P <.05). After the intervention, documentation improved to 79% of patients overall, with 7 individual practices achieving significant improvements (all P <.05). The greatest improvements in documentation occurred among patients treated in smaller practices (ie, 1-4 urologists). CONCLUSION: After collaborative review of staging criteria and feedback of baseline performance, urologists in MUSIC practices dramatically improved documentation of clinical TNM stage. This finding underscores the behavioral change possible with the collaborative quality improvement model and ensures the necessary risk stratification data for our ongoing efforts to improve care.
