COLORECTAL CANCER
Among GPs willing to prescribe aspirin, the factors participants agreed were important in their decision were the benefits of aspirin (527/540, 97.6%), the geneticist recommendation to prescribe (492/540, 91.1%), patient interest in using aspirin (491/540, 90.9%), and patient awareness of aspirin harms and benefits (519/540, 96.1%; The proportion of GPs (%) who agreed that each of the 14 factors influenced their willingness to prescribe (Those GPs unwilling to prescribe felt the most important factors influencing their decision were the harms of aspirin (121/132, 91.7%), benefits (113/132, 85.6%), dose being asked to prescribe (112/132, 84.8%), and prescribing off-label (110/132, 83.3%).A higher proportion of those unwilling to prescribe aspirin wanted to speak to a colorectal cancer specialist (96/132, 72.7%) before prescribing than those who were willing (224/540, 41.5%). The patient’s interest in aspirin factored less into the decision making of those unwilling (86/132, 65.2%) than those willing (491/540, 90.9%) to prescribe.In an open text box, participants were able to write additional factors that influenced their decision. Among unwilling GPs, 12.1% (16/132) suggested that the clinical geneticist should make the first prescription and 7.6% (10/132), that patients should buy aspirin from the pharmacy instead (Supplementary Table S5).
