Pharmacist Impact on Ischemic Stroke Care in the Emergency Department.

BACKGROUND: The Froedtert Acute Stroke Team (FAST) is composed of various health professionals who respond to stroke calls, but it does not formally include a pharmacist at this time. However, emergency department (ED) pharmacists have been actively involved in patient evaluation and facilitation of i.v. recombinant tissue plasminogen activator (rtPA) preparation and administration in the ED. ED pharmacists are qualified to dose and prepare rtPA, as well as screen for contraindications to therapy. OBJECTIVE: The primary objective was to compare the accuracy of rtPA dosing, mean door-to-rtPA time, and identification of contraindications to rtPA therapy when a pharmacist was present vs. absent in the ED. METHODS: This is a retrospective study of 105 patients who received rtPA for acute ischemic stroke in the ED at a comprehensive stroke center from January 1, 2008 to October 1, 2012. RESULTS: A total of 105 patients were included in this study. Dosing accuracy was similar when a pharmacist was present vs. absent (96.6% vs. 95.6%; p = 0.8953). The median door-to-rtPA time when a pharmacist was present was statistically significantly shorter than when a pharmacist was absent (69.5 vs. 89.5 min; p = 0.0027). When a pharmacist was present, a door-to-rtPA time of < 60 min was achieved 29.9% of the time, as compared with 15.8% in the pharmacist-absent group (p = 0.1087). CONCLUSIONS: Pharmacist involvement on stroke teams may have a beneficial effect on door-to-rtPA time and patient care in the ED.

Evaluation of treatment with direct thrombin inhibitors in patients with heparin-induced thrombocytopenia.

STUDY OBJECTIVE: To evaluate the efficacy, safety, and associated costs of anticoagulation with argatroban, bivalirudin, and lepirudin for managing patients with heparin-induced thrombocytopenia (HIT) or presumed HIT. DESIGN: Retrospective medical record review. SETTING: University-affiliated teaching hospital. PATIENTS: Forty-two patients who were hospitalized between January 1 and December 31, 2004, and who were treated with bivalirudin, argatroban, or lepirudin for at least 24 hours. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the time to reach the desired goal for activated partial thromboplastin time (aPTT). Secondary outcomes were the number of aPTT measurements within the therapeutic range, costs, treatment duration, clinical outcomes, and adverse events. Of the 42 patients who met the inclusion criteria, 24 received bivalirudin, 13 received argatroban, and 5 received lepirudin. Patients receiving bivalirudin who reached therapeutic aPTTs attained them sooner than those receiving either argatroban or lepirudin (8.5 vs 14 and 24 hrs, respectively, p=0.124). Average percentage of therapeutic aPTTs/patient was greatest in the argatroban group (62%), followed by the bivalirudin (57%) and lepirudin (29%) groups (p=0.062). Average drug cost/day/patient was greater in the lepirudin group than the other groups, whereas average laboratory costs were similar among groups. Treatment duration was longer with argatroban than with bivalirudin or lepirudin. Bleeding rates were similar in the argatroban and bivalirudin groups, but higher than in the lepirudin group. A composite of clinical outcomes (deep vein thrombosis, nonfatal myocardial infarction, nonfatal stroke, limb amputation, and all-cause mortality) were similar among the three groups. CONCLUSION: All three drugs were effective as anticoagulants for patients with HIT or presumed HIT. Based on average use and average wholesale price, bivalirudin cost less per day than the other two agents. Although not yet approved by the United States Food and Drug Administration for management of HIT, bivalirudin appears to be a viable treatment alternative for anticoagulation therapy.
