[A PROSPECTIVE STUDY TO INCREASE THE AWARENESS OF VENOUS THROMBOEMBOLISM PROPHYLAXIS IN INTERNAL MEDICINE WARDS].

Introduction: Venous thromboembolism (VTE) events are a significant risk factor for morbidity and mortality among hospitalized patients and 50-75% of the events occur in internal medicine wards. Despite the proven efficiency of prophylactic treatments, their usage in hospitals is underutilized. Multiple studies have shown that only 30-50% of the high risk VTE patients are treated prophylactically. Interventional programs were shown to significantly increase the awareness and hence, the percent of patients treated. However, there are no official guidelines for prophylaxis implementation among hospital personnel in Israel.

Methods: We conducted a prospective study of patients hospitalized in internal medicine wards to estimate the risk of VTE events and the prophylaxis rate. Patients were randomly selected and evaluated for VTE risk and treatment provided. During daily staff meetings on random sampling days, an open inquiry was conducted for each patient's management regarding VTE prophylaxis. This supervision was carried out for 3 consecutive months and 6 months later, to evaluate the implementation of the process.

Results: A total of 205 patients were sampled during the study. During the first month, 35% of the patients with indications for prophylaxis were treated. This percent increased to 50% in the second month, 60% in the third, and to 86% after six months (p<0.0001).

Conclusions: The awareness of VTE prophylaxis was low, and only a third of the patients with indications for prophylaxis were treated. The awareness implementation was slow and incremental, and increased from 35% to 86%. We conclude that the supervision and training on VTE prophylaxis is efficient and essential.
