Abstract
PURPOSE: Up to 15% of clinician-ordered doses of injectable pharmacological prophylaxis to prevent venous thromboembolism are not administered. Patient refusal accounts for nearly 50% of these omitted doses. We conducted a prospective cohort study to determine whether a patient education program would improve medication adherence to clinician-ordered injectable prophylactic anticoagulation.
METHODS: We identified 528 hospitalized patients ordered to receive injectable pharmacological venous thromboembolism prophylaxis. We evaluated the impact of pharmacist-led patient education sessions on medication adherence (defined as the ratio of doses administered to doses scheduled) compared with our historical cohort.
RESULTS: Individualized patient education sessions were conducted within 24 hours of the initial order for prophylactic anticoagulation in 99% of patients. Adherence to clinician-ordered pharmacological venous thromboembolism prophylaxis was higher after the patient education program than in our historical cohort (94.4% vs 89.9%, P <.0001). The proportion of patients receiving 100% of scheduled doses of injectable pharmacological venous thromboembolism prophylaxis was higher after our novel patient education program than in our historical cohort (73.7% vs 62.4%, P=.001). Patient refusal as a reason for omitted doses was less frequent after the patient education program (29.3% vs 43.7%, P=.001).
CONCLUSION: Pharmacist-led individualized patient education sessions were associated with higher medication adherence to clinician-ordered injectable pharmacological venous thromboembolism prophylaxis and a reduction in patient refusal as a reason for omitted doses. A randomized controlled trial to evaluate the impact of a patient education program on medication adherence to pharmacological venous thromboembolism prophylaxis is warranted.
