Improving hospital venous thromboembolism prophylaxis with electronic decision support

Area of Science:

• Medical Informatics
• Clinical Quality Improvement
• Thrombosis Medicine

Background:

• Venous thromboembolism (VTE) prophylaxis rates in medical inpatients are often below 50%.
• Low prophylaxis rates contribute to preventable morbidity and mortality.
• Effective strategies are needed to improve VTE prevention in hospitalized patients.

Purpose of the Study:

• To evaluate the effectiveness of a computerized decision support application in enhancing VTE prophylaxis.
• To assess the safety of implementing such a system.
• To compare VTE prophylaxis rates and outcomes before and after application implementation.

Main Methods:

• An observational cohort study was conducted at an academic medical center.
• A computerized decision support application was implemented on medicine services.
• Effectiveness (VTE prophylaxis rates, hospital-acquired VTE incidence) and safety (bleeding, thrombocytopenia) were compared pre- and post-implementation.

Main Results:

• VTE prophylaxis on medicine services increased significantly, from 61.9% to 82.1%.
• Pharmacologic VTE prophylaxis also rose significantly, from 59.0% to 74.5%.
• Hospital-acquired VTE incidence decreased on medicine services (0.65% to 0.42%), with a slight increase in bleeding rates.

Conclusions:

• Computerized decision support effectively improves VTE prophylaxis rates in hospitalized patients.
• The application led to a significant reduction in hospital-acquired VTE.
• The observed increase in bleeding rates was modest, suggesting a reasonable safety profile.
