The use of pharmacological prophylaxis against venous thromboembolism in hospitalised patients with severe active ulcerative colitis.

ABSTRACT: Hospitalised patients with inflammatory bowel disease are 1.5- to 3.5-fold more likely to develop venous thromboembolism compared to controls. Clinical guidelines recommend pharmacological prophylaxis.To determine the rate of pharmacological venous thromboembolism prophylaxis prescription and administration in a cohort of hospitalised patients with severe active ulcerative colitis and to assess predictors of failure to order pharmacological prophylaxis at 24 h.This is a retrospective review of hospitalised patients with severe active ulcerative colitis, identified by ICD-9-CM discharge code 556.x, admitted to a single tertiary care hospital from 1 January 2005 to 31 August 2012. Adequate thromboembolism prophylaxis was defined as an order for low-dose unfractionated heparin two to three times daily, low-molecular weight heparin 40 mg daily or fondaparinux 2.5 mg daily ordered and administered for >80% of the admission. Patient related factors associated with failure to order prophylaxis at 24 h were accessed as secondary outcomes.Three hundred and thirty-six patients were hospitalised with severe active ulcerative colitis. Hospitalists had prescribed appropriate pharmacological prophylaxis by 48 h in only 37% of cases. Of these, nurses administered all prescribed doses in 18% of cases. Only 7% of patients (22/304, 95% CI: 5-11%) received adequate pharmacological prophylaxis for >80% of their hospitalisation. Hematochezia (P = 0.002), elevated platelets (P = 0.008), male gender coupled with younger age (P = 0.005) and admission on a biologic (P = 0.03) were associated with failure to order prophylaxis.Hospitalised patients admitted with severe active ulcerative colitis are not receiving appropriate pharmacological venous thromboembolism prophylaxis.
