Abstract

Copyright © 2015 by American Society of Clinical Oncology. Purpose: For patients with resected non-small-cell lung cancer, national guidelines recommend cisplatin-based doublet chemotherapy as the preferred treatment. However, many patients receive a carboplatin-based regimen instead. We aimed to identify factors associated with use of a cisplatin-based regimen and explore its association with other quality-of-care measures. Methods: This analysis was part of the Florida Initiative for Quality Cancer Care, an audit and feedback project among 11 medical oncology practices. Feedback-sharing sessions based on findings of year 2006 took place in 2008. Eligible patients were random samples of those with resected stage I to III non-small-cell lung cancer treated in 2006 and 2009. Results: In both years combined, 81 patients received adjuvant platinum-based doublets: 33 patients (41%) received cisplatin, and 48 patients (59%) received carboplatin. Use of a cisplatin-based doublet significantly increased in 2009 compared with 2006, from 24% to 56% (P = .006). Multivariable analysis determined that academic practices used cisplatin more frequently than nonacademic practices (odds ratios, 3.26; 95% CI, 1.19 to 8.91; P = .02). Moreover, patients treated in 2009 were more likely to receive cisplatin than those treated in 2006 (odds ratio, 4.89; 95% CI, 1.75 to 13.67; P = .002). No significant association between use of cisplatin and other quality-of-care measures was found. Conclusion: In this study, academic practice status and treatment year predicted use of adjuvant cisplatin-based chemotherapy. The increase in use of cisplatin in 2009, as compared with 2006, suggests that audit and feedback may be effective ways to promote such use.
