[Thromboprophylaxis in hospitalized patients: implementation of a multifacetical program]

Venous thromboembolic disease is the most common preventable cause of hospital death. Despite the existence of evidence of the usefulness of thromboprophylaxis and recommendations, adherence by physicians to them is highly variable, and frequently suboptimal. The objective was to evaluate the change in the adequacy of thromboprophylaxis before and after an intervention on thromboprophylaxis with multifaceted strategies for physicians. The intervention was a 6 years institutional program with multiple strategies: passive actions such as posters and active actions as continuous medical education, adaptation of an institutional clinical practice guide and a computerized clinical decision support system. The baseline adequacy of thromboprophylaxis improved from 59% to 82% and was maintained over time. The improvement in fitness was associated with a reduction in major bleeding, particularly in patients undergoing surgery.
