Enoxaparin adherence for venous thromboembolism prophylaxis in hospitalized patients with sickle cell disease

BackgroundVenous thromboembolism (VTE) is a common cause of morbidity and mortality in patients with sickle cell disease (SCD).MethodsThis retrospective study assessed adherence to prescribed enoxaparin for VTE prophylaxis in adults with SCD while hospitalized. A total of 172 encounters of 72 unique patients were evaluated between 1 January and 31 December 2019. Patients were grouped based on adherence to prescribed enoxaparin. Group 1 received 100% of doses ordered. Group 2 received between 99% and 1% of doses ordered. Group 3 received 0% of doses ordered.ResultsOnly 45 encounters (32.3%) received 100% of ordered doses and 81 encounters (47%) did not receive any of the ordered enoxaparin doses. In total, only 37% of all prescribed enoxaparin doses were administered to patients.ConclusionThis low level of administered enoxaparin is concerning in a patient population at an increased risk for VTE. VTE prophylaxis adherence needs to be addressed with each admission and, if appropriate, alterative options to enoxaparin should be considered.
