Appropriateness of Beta-Lactam Allergy Record Updates After an Allergy Service Consult.

BACKGROUND: Many patients with a self-reported penicillin allergy go on to tolerate beta-lactam antibiotics. Allergy specialists may be consulted to determine the nature and extent of the allergy. However, electronic allergy records must be appropriately updated such that recommendations are carried forward. OBJECTIVE: To determine the percentage of patients who have their electronic allergy record updated after an allergy service consult (ASC). METHODS: This was a retrospective study of patients with at least 1 documented beta-lactam allergy and had an ASC during (inpatient) or prior to (outpatient) hospital admission at Northwestern Memorial Hospital and Prentice Women's Hospital in Chicago, Illinois. RESULTS: Within the study period, a total of 26 526 patients were identified as having a documented antibiotic allergy, with 21 657 patients (81.6% of patients with allergies) having a listed beta-lactam allergy. Of these patients, 1689 (7.8%) patients were identified as having an ASC during or prior to admission, with 598 patients meeting inclusion criteria. Changes in the allergy record were recommended by the ASC for 62% (n = 371) of patients; however, the allergy record was updated after the ASC in 74.9% (n = 278) of patients. CONCLUSION: ASC recommendations to delabel a patient as beta-lactam allergic must result in updating the allergy record in order to optimize future treatment. Given the low proportion of allergy-labeled patients tested, programs outside formal ASCs should be considered.

Time Requirements for Acquisition of Hepatitis C Virus Therapy in HIV/HCV Coinfected Patients.

Background: The process of obtaining approval for hepatitis C virus (HCV) treatment may be time consuming and complicated due to prior authorizations and the need to appeal denials. Pharmacists are poised to play a critical role in the acquisition and management of oral direct acting antivirals (DAAs) for the treatment of HCV infection; however, the time expended in this activity requires assessment. Objective: The objective of this study was to assess time expenditures by pharmacists to acquire DAAs for HCV therapy. Methods: Patients were enrolled in the Northwestern University Viral Hepatitis Registry, a prospective, observational cohort of ambulatory, adult patients living with human immunodeficiency virus (HIV) coinfected with chronic hepatitis B and/or C virus, and recruited since 2013 from the Infectious Disease Center at Northwestern Memorial Hospital, Chicago, IL. Patients were included in the current study if they were referred to the pharmacist for HCV DAA acquisition, drug-drug interaction management, and adherence counseling between February 1, 2014, and April 30, 2015. Patient demographics, virus-specific characteristics, and time required to secure HCV DAA treatment, counsel patients, and follow-up therapy were collected. Results: Among 54 HIV/HCV coinfected patients referred for treatment, all eventually received approval for DAA therapy. However, 87% (n = 47) required prior authorization. Pharmacists dedicated 2.1 hours/patient (interquartile range 1.5-2.8 hours; range 0.75-6.5 hours) to manage DAA therapy. Conclusion: Successful acquisition of HCV DAA therapy relied heavily on pharmacist effort, reflecting the vital role that pharmacists play in this process. Dedicated resources for medication access should be considered to ensure timely DAA acquisition.
