Process Improvements Positively Impact the Use of Intravesical Mitomycin C after Transurethral Resection of Nonmuscle Invasive Bladder Cancer in a Large, Urban Urology Practice. Issue 6 (November 2015) - Cusano, Joseph
Abstract : Introduction: : We assessed the rate of intravesical mitomycin C therapy in patients with nonmuscle invasive bladder cancer who underwent transurethral resection of the bladder, as well as the impact of procedural changes governing its use. Methods: : A retrospective review of our bladder cancer database identified patients who underwent transurethral resection of the bladder with mitomycin C therapy during January 2008 to July 2014. Since our mitomycin C protocols were revised during 2013, patients were stratified based on date of service. Patient demographics and data describing mitomycin C use were tabulated. Results: : During January 2008 to May 2013, 276 of 737 (37.5%) ideal patients received mitomycin C (not accounting for patients in whom mitomycin C was contraindicated). Conversely 461 of 737 patients (62.5%) did not receive mitomycin C. Shortages of mitomycin C were responsible for nonuse in 18.4% of cases while no specified reason for nonuse was given in 59%. When cases in which mitomycin C use was contraindicated were taken into account, mitomycin C was used in 51.6% overall. After the implementation of new mitomycin C operating procedures, mitomycin C use increased significantly to 76.0% (p <0.001) (accounting for appropriate nonuse). During this period mitomycin C shortages were not responsible for any case in which mitomycin C was not used. Conclusions: : During 2008 to 2013 mitomycin C was not used in a significant proportion of patients who underwent transurethral resection of the bladder. The implementation of a revised protocol governing mitomycin C use significantly and positively impacted mitomycin C use. Importantly, pharmacy shortages no longer contribute to the nonuse of mitomycin C in patients with bladder cancer. These data highlight the impact of continual improvement initiatives on standard clinical practice.
