RESUMEN

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.

RESUMEN

Background Unpredictable drug concentrations may lead to suboptimal exposure to nucleoside reverse transcriptase inhibitors (NRTIs) due to inadequate doses administered during continuous veno-venous hemofiltration (CVVH), which in turn may lead to decreased antiretroviral efficacy and possibly further HIV disease progression. Objective To compare administered doses of NRTIs to calculated doses of NRTIs to evaluate if patients were expected to have a favorable pharmacokinetic exposure profile while receiving CVVH. Methods The NRTI dose was compared to a table of recommendations based on a mathematical formula that estimates the amount of drug expected to be removed during CVVH. Results Twelve patients were on 27 NRTIs. Eleven (41%) NRTI doses were expected to provide a favorable pharmacokinetic profile based on pharmacokinetic mathematical calculations. Conclusion The majority of NRTIs were potentially not optimally dosed based on proposed pharmacokinetic calculations.
