[Evaluation of venous thromboembolism prophylaxis in a high complexity hospital].

Objective: This study aimed at assessing the adequacy of thromboprophylaxis in a high complexity hospital in Vitória-ES, analysing the possible predictors of inadequate prescriptions and/or procedures.

Methods: A cross-sectional study was carried out through prompt-book analysis. The included patients were hospitalized in 2007 and had their Venous thromboembolism (VTE) risk stratified using the 8th Edition of the American College of Chest Physicians (ACCP) Evidence-Based Clinical Practice Guidelines. The thromboprophylaxis adequacy was determined through a comparison between the adopted prescriptions and/or procedures and the guideline recommendations. EpiInfo 3.4.3 and SPSS 13.0 were the software applications used.

Results: In 47% of the patients the thromboprophylaxis was inadequate, being the non-prescription of the indicated medication the major reason (33%). There was no statistically significant difference in inadequate tromboprophylaxis rate between clinical and surgical patients, or ward and Intensive care unit (ICU) ones. An inverse relationship was observed between the inadequate tromboprophylaxis rate and the number of VTE risk factors presented by the patients, as well as their age, and the length of hospital stay (p < 0.05).

Conclusion: The results show alarming levels of thromboprophylaxis inadequacy, inacceptable in these times of well-established published guidelines. Therefore, a continuing education program should be implanted for all the assistance team.
