Background: Didactic lectures are frequently used to improve compliance with practice guidelines. This study assessed the knowledge of health-care providers (HCPs) at a tertiary-care hospital of its evidence-based thromboprophylaxis guidelines and the impact of didactic lectures on their knowledge.
Methods: The hospital launched a multifaceted approach to improve thromboprophylaxis practices, which included posters, a pocket-size guidelines summary and didactic lectures during the annual thromboprophylaxis awareness days. A self-administered questionnaire was distributed to HCPs before and after lectures on thromboprophylaxis guidelines (June 2010). The questionnaire, formulated and validated by two physicians, two nurses and a clinical pharmacist, covered various subjects such as risk stratification, anticoagulant dosing and the choice of anticoagulants in specific clinical situations.
Results: Seventy-two and 63 HCPs submitted the pre- and post-test, respectively (62% physicians, 28% nurses, from different clinical disciplines). The mean scores were 7.8 ± 2.1 (median = 8.0, range = 2-12, maximum possible score = 15) for the pre-test and 8.4 ± 1.8 for the post-test, P = 0.053. There was no significant difference in the pre-test scores of nurses and physicians (7.9 ± 1.7 and 8.2 ± 2.4, respectively, P = 0.67). For the 35 HCPs who completed the pre- and post-tests, their scores were 7.7 ± 1.7 and 8.8 ± 1.6, respectively, P = 0.003. Knowledge of appropriate anticoagulant administration in specific clinical situations was frequently inadequate, with approximately two-thirds of participants failing to adjust low-molecular-weight heparin doses in patients with renal failure.
Conclusions: Education via didactic lectures resulted in a modest improvement of HCPs' knowledge of thromboprophylaxis guidelines. This supports the need for a multifaceted approach to improve the awareness and implementation of thromboprophylaxis guidelines. |
