Cancer drug shortages: Awareness and perspectives from a representative sample of the US population

Abstract

BACKGROUND: Although cancer drug shortages are a persistent problem in oncology, little is known about the awareness and perspectives of the US population with respect to shortages. METHODS: In 2016, we administered a 13-item cross-sectional survey to 420 respondents who were randomly selected from an online, probability-based sample demographically representative of the adult US population with respect to sex, age, race/ethnicity, education, geography, and income. Analyses applied poststratification sampling weights to draw national inferences. RESULTS: Overall, 16% of respondents reported being aware of drug shortages. Those with a personal history of cancer were more likely to be aware (31% vs 14% [P =.03]). In the overall cohort, most reported wanting to be informed about a substitution due to shortage: 87% and 82% for major or minor differences in efficacy, and 87% and 83% for major or minor differences in side effects. Most also reported they would transfer care to avoid a substitution: 72% for major differences in efficacy, and 61% for major differences in side effects. Black respondents, the uninsured, the unemployed, those with lower income, and the less well-educated were all less likely to report that they would transfer care to avoid major differences in efficacy (all P
