COLORECTAL CANCER
In this online factorial experiment, it was found that highlighting the clinical guidance, summarising trial evidence, or giving information on aspirin’s benefits and harms did not increase GPs’ willingness to prescribe aspirin for colorectal cancer prevention.Reassuringly, most GPs participating in the experiment were willing to prescribe aspirin for a hypothetical patient with LS. However, a fifth of GPs were unwilling. Most GPs who were unwilling described several barriers that behavioural interventions are unlikely to affect, such as the harms of aspirin and prescribing off-label. Alternative strategies targeting multiple levels of prescribing behaviours may be warranted, including targeted support for GPs unwilling to prescribe.
