Therefore, the goal of the study was to characterize disparities in the compliance rates to quality measures. METHODS The Comparative Effectiveness Analysis of Radiation Therapy and Surgery (CEASAR) study is a population-based, prospective cohort study that enrolled 3708 men with clinically localized prostate cancer from 2011-12. Compliance with 4 radiation-specific quality measures endorsed by national consortia as of 2011 was assessed (Table), and compliance was compared by race using logistic regression. RESULTS Overall, 634 men received definitive external beam radiation therapy (EBRT) of which 19% were self-reported African-American (AA), 70% Non-Hispanic White (NHW), and 11% Hispanic, Asian, and other (HAO). The median time from diagnosis to EBRT was significantly longer for AA and HAO then NHW men (3.0, 3.6 months vs. 2.7, p<0.01). Less than two-thirds of AA (64%) and HAO men (62%) received EBRT that adhered to all quality measures, compared to 77% of NHW men (p<0.01 ). The disparity in compliance to quality measures was noted in the proportion receiving dose-escalated (> 75 Gy) EBRT (87% AA, 88% HAO vs. 95% NHW, p<0.01). The proportion of men receiving prostate-only EBRT without nodal EBRT for low-risk disease was lower among AA than NHW or HAO (80% AA vs. 99% NHW, 100% HAO, p<0.01), while the proportion having image-guidance EBRT was lowest among HAO (73%) compared to NHW or AA (87%, 88%, p=0.02). On a logistic regression predicting compliance to all the quality measures, AA and HAO men had almost half the odds of receiving quality EBRT than NHW men (OR 0.54, 0.5 p=0.02), after adjusting for education, insurance status, and D'Amico risk. CONCLUSIONS Minority men were less likely to receive dose-escalated EBRT which improves prostate cancer control, and were more likely to receive unnecessary nodal radiation for low-risk prostate cancer that increases treatment side effects. There may be opportunities to improve care by enhancing adherence to quality measures among vulnerable groups via implementation initiatives. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e1229 Advertisement Copyright & Permissions© 2017MetricsAuthor Information Daniel Lee More articles by this author Joann Alvarez More articles by this author Tatsuki Koyama More articles by this author Matthew Resnick More articles by this author David Penson More articles by this author Daniel Barocas More articles by this author Karen Hoffman More articles by this author Ceasar Investigators More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
