Background: Adequate thromboprophylaxis reduces the risk of venous thromboembolism (VTE) by half in hospitalized patients. A single scoring system is recommended to improve thromboprophylaxis.
Objectives: We investigated the impact of implementing a computerized system to prevent VTE in inpatients with pulmonary diseases and identified predictors of the overuse and underuse of pharmacological thromboprophylaxis.
Material and methods: We compared the use of thromboprophylaxis with enoxaparin in all patients hospitalized for pulmonary disorders in a tertiary hospital in Kraków, Poland, in 2014 and 2017, before and after introducing a computerized thromboprophylaxis system. Using the Caprini risk assessment, the overuse and underuse of thromboprophylaxis were defined as the use in patients with <5 points and ≥5 points, respectively.
Results: Both cohorts (n = 2007 in 2014 and n = 1570 in 2017) were similar with regard to age and sex. The most frequent causes of hospitalization were intestinal lung disease (39.0%) and lung cancer (20.4%) in 2017, and pneumonia (38.8%) and lung cancer (27.5%) in 2014. Although the use of thromboprophylaxis was comparable in both cohorts, it was used more frequently in high VTE risk patients in 2017 compared with 2014 (96.98% compared to 29.17%, respectively, p < 0.001), with a concomitant reduction in its overuse (2.26% compared to 6.26%, respectively, p < 0.001). In 2017, no predictors of thromboprophylaxis underuse were identified. The overuse was mainly predicted by the diagnosis of airway diseases (odds ratio (OR) = 0.16, 95% confidence interval (95% CI) = 0.02-1.17, p = 0.015).
Conclusions: Our findings indicate the benefits of using a computerized system to manage pharmacological thromboprophylaxis in pulmonary inpatients.
