Adherence to national guidelines for antiemesis prophylaxis in patients undergoing chemotherapy for lung cancer: A population-based study

Research output: Contribution to journalArticle

Abstract

BACKGROUND: Nausea and vomiting (N/V) during chemotherapy can have profound clinical and economic consequences. Effective antiemetic agents are available for prophylaxis, but barriers may prevent their use. For this population-based study, the authors assessed the rates of antiemetic prophylaxis use, and predictors of such use, among patients who were receiving platinum-based chemotherapy for lung cancer between 2001 and 2007. METHODS: The authors searched the Texas Cancer Registry-Medicare-linked database for individuals aged >65 years who received platinum-based chemotherapy within 12 months after a first diagnosis of lung cancer from 2001 to 2007; and all patients had continuous Medicare Part A and Part B coverage for the same period. Adherence to recommended regimens for N/V prophylaxis (established by the National Comprehensive Cancer Network) was scored as a binary variable (adherent vs nonadherent) and was calculated as the percentages of treated patients receiving each recommended agent within 1 day of beginning chemotherapy. Logistic regression with stepwise selection was used to examine whether patient characteristics influenced adherence. RESULTS: Of 4566 selected patients, adherence rates for the receipt of serotonin antagonists (eg, ondansetron) with dexamethasone were 60% to 90% regardless of whether the chemotherapy agent was considered moderately or highly emetogenic. The receipt of substance-P antagonists was much less common (<10%) during any period. On multivariate logistic regression modeling, variables that predicted adherence were older age, white race, higher median income, and concurrent radiation therapy. CONCLUSIONS: Recommended use of antiemetics for prophylaxis, especially substance-P antagonists, during chemotherapy for lung cancer is suboptimal. Factors that were correlated with adherence suggest socioeconomic barriers in the community. Cancer 2013. © 2012 American Cancer Society. Adherence to antiemetic prophylaxis for chemotherapy-induced nausea and vomiting can have a significant impact on clinical and economic outcomes. The authors use a population database both to assess the rate of adherence to antiemetic prophylaxis in patients with lung cancer and to determine the factors that predict for improved compliance.
