Background
All hospitalized patients should be assessed for VTE risk factors and prescribed appropriate prophylaxis. To improve best-practice VTE prophylaxis prescription for all hospitalized patients, we implemented a mandatory computerized clinical decision support (CCDS) tool. The tool requires completion of checklists to evaluate VTE risk factors and contraindications to pharmacologic prophylaxis, and then recommends the risk-appropriate VTE prophylaxis regimen.
Objectives
To examine the effect of a quality improvement intervention on race- and gender-based healthcare disparities across two distinct clinical services.
Research Design
Retrospective cohort study of a quality improvement intervention
Subjects
1942 hospitalized medical patients and 1599 hospitalized adult trauma patients
Measures
Proportion of patients prescribed risk-appropriate, best-practice VTE prophylaxis
Results
Racial disparities existed in prescription of best-practice VTE prophylaxis in the pre-implementation period between black and white patients on both the trauma (70.1% vs. 56.6%, p=0.025) and medicine (69.5% vs. 61.7%, p=0.015) services. After implementation of the CCDS tool, compliance improved for all patients and disparities in best-practice prophylaxis prescription between black and white patients were eliminated on both services: trauma (84.5% vs. 85.5%, p=0.99) and medicine (91.8% vs. 88.0%, p=0.082). Similar findings were noted for gender disparities in the trauma cohort.
Conclusions
Despite the fact that risk-appropriate prophylaxis should be prescribed equally to all hospitalized patients regardless of race and gender, practice varied widely prior to our quality improvement intervention. Our CCDS tool eliminated racial disparities in VTE prophylaxis prescription across two distinct clinical services. Health information technology approaches to care standardization are effective to eliminate healthcare disparities.
