RESUMO
Venous thromboembolism (VTE) prophylaxis in high-risk patients is frequently underutilised. We previously devised a one-screen computer alert program that identified hospitalised patients at high risk for VTE who were not receiving prophylaxis and advised their physicians to prescribe prophylaxis. While this strategy reduced the 90-day incidence of symptomatic VTE by 41%, the majority of electronic alerts were ignored. We have now developed a serial three-screen alert computer program designed to educate physicians who initially declined to order prophylaxis after a single screen alert. Of a total cohort of 880, the responsible physicians for 425 patients received a single electronic alert, whereas 455 who declined prophylaxis after the first screen received the second and third screens of the novel three-screen alert. Our enhanced serial three-screen alert program generated VTE prophylaxis orders for 58.4% of the 455 patients whose physicians initially declined to order prophylaxis following the one-screen alert. There was no significant difference in symptomatic 90-day VTE rates between the two cohorts (2.8% for the one-screen vs. 2.2% for the three-screen, p=0.55). We conclude that our three-screen computer alert program can markedly increase prophylaxis among physicians who decline an initial single screen alert.
