Computerized support systems to prevent VTE
Man or machine, which is better at decreasing the risk of venous thromboembolism (VTE) in surgical patients? According to the present US-American study, the machines win this particular contest hands down: computerized clinical decision support systems (CCDSSs) decrease VTE events compared to routine care without decision support. The authors therefore suggest implementing these systems to help clinicians assess the risk of VTE and provide prophylaxis against VTE events in surgical patient populations.
The authors included eleven studies (nine prospective cohort trials, two retrospective cohort trials, n=156,366) comparing CCDSSs with VTE risk stratification among surgical patients. Main outcomes and measures were rates of prophylaxis for VTE and VTE events.
The use of CCDSSs was associated with two positive outcomes: one, a significant increase in the rate of appropriate ordering of prophylaxis for VTE (odds ratio, 2.35; P < 0.001) and two, a significant decrease in the risk of VTE events (risk ratio, 0.78; P < .001).
Employing computerized clinical decision support systems can increase the proportion of surgical patients who were prescribed adequate prophylaxis for VTE. In addition, the use of computerized systems correlates with a reduction in VTE events, conclude the authors.
