简要总结
This nationally representative randomized survey of US adults will evaluate the effect of using brief statements to communicate multiple different sources of uncertainties about the benefits and harms of new cancer drugs on participants' decisions.
详细描述
Many newer cancer drugs are approved before uncertainties with their underlying clinical trial evidence have been adequately studied, in turn making it difficult to accurately determine the drug's benefits and harms. Prescription drug information rarely communicates these uncertainties. In a nationally representative sample of US adults, this study will evaluate the effect of using brief statements to communicate multiple different sources of uncertainties about the benefits and harms of new cancer drugs on participants' decisions.
In the pre-intervention phase, participants will be given information about a hypothetical new drug approved for the treatment of non-small cell lung cancer. Participants will be asked how likely they would be to take the drug, and how certain they are that the drug will work. Participants will then be randomized with equal allocation to 1 of 5 groups. The control group will receive information about a new cancer drug's benefits and harms; the intervention groups will also be given brief statements about sources of uncertainties with the drug's evidence (1, 2, 3, or 4 sources of uncertainties). The post-intervention questions will re-assess participants' decision making, perceptions of uncertainty, emotions, understanding, and trust.
