Regional Collaboration to Improve Radiographic Staging Practices Among Men With Early Stage Prostate Cancer

PurposeWe describe findings from a Urological Surgery Quality Collaborative project focused on improving the use of radiographic staging in men with newly diagnosed prostate cancer.Materials and MethodsFrom May 2009 through September 2010 Urological Surgery Quality Collaborative surgeons collected uniform data for men with newly diagnosed prostate cancer. During this period we implemented 3 phases of data collection. Unlike the baseline phase, the second and third rounds were preceded by collaborative quality improvement interventions, including comparative performance feedback, and review and dissemination of clinical guidelines. We evaluated the use of bone scans and computerized tomography across prostate cancer risk strata, Urological Surgery Quality Collaborative practice locations, and before and after quality improvement interventions.ResultsWe collected data for 858 men with prostate cancer. Based on the D'Amico classification 44%, 39% and 17% of the men had low, intermediate and high risk cancer, respectively. Overall 25% and 22% of patients underwent staging with a bone scan or computerized tomography, respectively, ordered by a Urological Surgery Quality Collaborative urologist. Urological Surgery Quality Collaborative practices differed significantly in their baseline use of bone scans and computerized tomography for men with low and intermediate risk cancer (p <0.01). Compared with baseline practice patterns (31% bone scans, 28% computerized tomography), urologists in Urological Surgery Quality Collaborative practices ordered fewer bone and computerized tomography scans in post-intervention phases 2 (23%, 21%) and 3 (16%, 13%) of data collection (p <0.01), including a significant reduction in the use of these studies in patients with low and intermediate risk cancer (p <0.05).ConclusionsFollowing collaborative feedback on baseline use and review of clinical guidelines, urologists in Urological Surgery Quality Collaborative practices dramatically reduced variations in practice patterns and improved adherence with recommended staging practices.
