Evaluation of the Use of Low-Dose 4-Factor Prothrombin Complex Concentrate in the Reversal of Direct Oral Anticoagulants in Bleeding Patients.

OBJECTIVE: This study investigated the percentage of patients who achieved hemostasis with 4-factor prothrombin complex concentrate (4-factor PCC) 35 U/kg. The primary end point was to determine the effect of 4-factor PCC 35 U/kg on bleeding progression, assessed using computed tomography. METHODS: This was a retrospective, observational, single-center study conducted in patients with a major bleed admitted to a level 1 trauma center from May 1, 2013, to June 15, 2015, who received 4-factor PCC 35 U/kg for reversal of a direct factor Xa inhibitor taken prior to admission. RESULTS: Thirty-three patients were included in the study, with 31 patients in the final analysis. The mean (standard deviation) age was 73 (14.8) years; 54.5% of patients were female. Of the 33 patients, 13 presented with a traumatic brain injury, 9 with an aneurysmal subarachnoid hemorrhage, 8 with an intracerebral hemorrhage, 1 with a gastrointestinal bleed, 1 with a hematoma with active extravasation, and 1 with an intra-abdominal bleed. The most frequently used direct factor Xa inhibitor was rivaroxaban (81.8%). Overall, 83.8% of patients achieved hemostasis with 4-factor PCC 35 U/kg. Progression of hemorrhage was observed in 4 patients on repeat computed tomography scan and 1 patient had continued surgical bleeding. No thromboembolic events were reported. CONCLUSIONS: Low-dose, 4-factor PCC 35 U/kg appeared to produce hemostasis in a majority of the patients. This may be an effective dosing regimen for anticoagulant reversal of factor Xa inhibitors in clinically bleeding patients.

Bivalirudin Medication Use Evaluation and Cost Savings Initiative.

Bivalirudin is a parenteral anticoagulant that elicits its effect through inhibition of both free and clot bound-thrombin. Inhibition of thrombin serves as a unique mechanism for anticoagulation when compared to heparin as thrombin serves as the final common pathway for the intrinsic and extrinsic coagulation cascades. Due to unclear benefit over heparin, concerns regarding reversibility, and most importantly cost its use as a parenteral anticoagulant varies by institution. A recent drug expenditure review within our institution noted a significant increase in the contribution bivalirudin had on the overall drug budget. In an effort to establish the rationale for the cost increase, a medication use evaluation was performed. While it was discovered that 625 out of 1364 days of bivalirudin therapy were potentially avoidable, an equally important discovery was the amount of waste that was associated with bivalirudin therapy. Calculating daily requirements for bivalirudin indicated that 60% of patients required less than 100 mg per day. Within this article, we describe a cost-savings initiative to reduce bivalirudin waste and the resulting cost-avoidance following implementation.

Protocol-Driven Allied Health Post-Discharge Transition Clinic to Reduce Hospital Readmissions in Heart Failure.

BACKGROUND: Heart failure (HF) patients have high rates of hospitalization and rehospitalization. METHODS AND RESULTS: A protocol-driven clinic staffed by an allied health care team was designed for patients discharged from the hospital with a diagnosis of congestive HF. The clinic provided follow-up visits 1 week and 4 to 6 weeks after hospital discharge. One-hundred and fourteen patients were observed at least 1 time, and 80% of these patients completed the 2-visit protocol. Clinical evaluations were provided by a nurse practitioner specializing in HF and a clinical pharmacist; these evaluations included physical examination, laboratory evaluation, medical education and reconciliation, medication adjustment and titration, and care coordination. Referrals to home health and appropriate services were provided. At visit 1, 25% of patients were hypervolemic and 13% were hypovolemic. At visit 2, 20% were hypervolemic and 13% were hypovolemic. Medicine reconciliation errors were common, with an average of 2.1 and 0.8 errors per person recorded for visits 1 and 2, respectively. Clinic participants showed a 44.3% reduction in 30-day readmission rates, as compared to the hospital's average 30-day readmission rates. CONCLUSIONS: Protocol-driven postdischarge transition care delivered by allied health staff addressed multiple transition issues and was associated with a dramatic reduction in readmission rates.
