Thromboprophylaxis use and concordance with guidelines among medical and surgical patients in Morocco

Introduction No data are available on thromboprophylaxis use in Morocco. Our aim was to characterize patients at risk of venous thromboembolism and assess the rate of appropriate thromboprophylaxis. Materials and Methods This was a national, observational, multicentre survey of venous thromboembolism risk and thromboprophylaxis use in hospitalized patients. Data were collected on a predefined date in three university hospitals in Morocco using a standardized pre-printed form. Thromboembolic risk was assessed according to the American College of Chest Physicians (ACCP) 2008 guidelines. Patients were classified as "thromboprophylaxis indicated" or "thromboprophylaxis not indicated". Results 784 patients were analysed: 307 (39.2%) medical and 477 (60.8%) surgical. 421 (53.7%) were female. Medical patients were older than surgical patients (57.6 ± 11.5 vs. 46.2 ± 16.9 years, p < 0.0001) and were more likely to have risk factors for thromboembolism (50.5% vs. 45.7% of patients, p = NS). 57% of patients without contraindications or bleeding risk were at risk of thromboembolism according to ACCP guidelines and thromboprophylaxis was prescribed to 42.8% of these patients. In contrast, 7.4% of patients with no thromboembolic risk also received thromboprophylaxis (proportion agreement: 61.0%; Kappa = 0.296). Over half (54.5%) of medical patients at risk of thromboembolism did not receive thromboprophylaxis whereas 6.3% of those with no risk did receive it (proportion agreement: 76.4%; Kappa = 0.433). These figures were 57.9% and 9.2%, respectively, for surgical patients (proportion agreement: 52.7%; Kappa = 0.191). Thromboprophylaxis was given to 19.2% of patients with contraindications or a bleeding risk. Conclusions Educational initiatives are imperative to inform doctors about appropriate thromboprophylaxis. © 2014 Elsevier Ltd. All rights reserved.
