While those are representative scenarios of the most usual practices, unstudied scenarios cannot not be excluded, especially since penicillin allergy testing is highly heterogeneous [86] and antibiotic utilization patterns vary globally. Penicillin and Beta-Lactam Hypersensitivity. Review our cookies information for more details. In all decision models, testing was cost-saving in more than half of simulations. Indeed, the particularly high incremental net benefits obtained with models assessing European outpatients are likely explained by the existence of only a single Dutch study that compared the frequency of outpatient visits among patients with and without a penicillin allergy label, and which found large differences [13]. Objective: To assess the safety and impact of penicillin allergy evaluation in pregnant patients. Ann Allergy Asthma Immunol. hCorresponds to estimates obtained by means of formal cost assessments; survey-obtained data were solely used in the context of survey-retrieved amounts.. Sacco KA, Bates A, Brigham TJ, Imam JS, Burton MC. PRE-PEN is indicated for the assessment of sensitization to penicillin (benzylpenicillin or penicillin G) in patients suspected to have clinical penicillin hypersensitivity. 1 In sensitivity analyses, lower cost estimates were achieved when only a drug challenge was performed (ie, no skin test, $84) and a nurse practitioner provider was used ($170). Safety of direct drug provocation testing in adults with penicillin allergy and association with health and economic benefits. A penicillin allergy is more commonly reported than an allergy to any other drug class [1]. An official website of the United States government. Another important limitation results from the fact that literature-based evidence was obtained by studies that often adopted different methodologies and definitions.

When you take penicillin, the medicine destroys the outer wall of bacterial cells. Penicillin Allergy - The New England Journal of Medicine: Research Chiriac Using TDABC, penicillin allergy evaluation costs $220; even with varied assumptions adjusting for operational challenges, clinical setting, and expanded testing, penicillin allergy evaluation still costs only about $540. Sequential diagnostic workup corresponds to the performance of skin tests followed, if negative, by drug challenges. Autoridade Nacional do Medicamento e Produtos de Sade (Infarmed). Many patients with a penicillin allergy label do not have a true allergy and may be safely treated with penicillin. Background: Penicillin allergy testing has been found to be safe in pregnancy and cost-effective in other patient populations. Keywords: T, Broekhuizen BDL, Verheij TJM, Rockmann H.

The former workflow was based on current recommendations [18, 19] and consisted of skin tests being performed to all individualsif positive, patients were considered to be truly allergic to penicillins; if negative, individuals were subject to a subsequent DC (a positive DC indicated that the patient is truly allergic to penicillins, while a negative DC indicated penicillin tolerance). Direct diagnostic testing corresponds to the direct performance of drug challenges without prior skin tests (either in all patients or only in those reporting nonimmediate reactions). K01 AI125631/AI/NIAID NIH HHS/United States. B, Blumenthal KG, Macy E, et al. A positive reaction to a test will cause a red, itchy, raised bump. Incremental, MeSH In addition to findings related to hospital care, studies estimate that the presence of a reported penicillin allergy is associated with higher costs from outpatient antibiotics. However, these results are based on existing evidence and on model-based simulation methods. Uncertainty was explored via probabilistic sensitivity analyses. aDirect drug challenges correspond to drug challenges without prior skin tests. To estimate the cost of penicillin allergy evaluation using time-driven activity-based costing (TDABC).

Copyright 2017 American Academy of Allergy, Asthma & Immunology. 75% of simulations obtained through probabilistic sensitivity analysis identified testing as the less costly option. 2023 Jan 20;18(1):e0280151. In addition to skin tests and DC, the European Network for Drug Allergy recommends the performance of in vitro tests for patients reporting immediate reactions. In fact, 68.9% of simulations identified testing as the least expensive strategy when considering a percentage of positive IgE results of 13.5%, and average quantification costs of $46 for inpatients and $71 for outpatients [21, 85]. Supplementary Figure 1 illustrates the selection process resulting in the identification of the included studies. An incremental net benefit >0 identified testing as the less costly alternative. Our input parameters were obtained from diverse information sources, including scientific literature, administrative databases, and technical reports. cSum of costs involving (1) performance of penicillin allergy tests and (2) consequences (as expressed in monetary units) resulting from healthcare use. Abbreviation: US, United States. Background: Having a penicillin allergy label is associated with the use of less appropriate and more expensive antibiotics and increased healthcare utilization. eCollection 2022 Dec. Antibiotic allergy labels in children are associated with adverse clinical outcomes, The economic burden of antibiotic treatment of penicillin-allergic patients in internal medicine wards of a general tertiary care hospital. However, data on the accuracy and costs of IgE quantification are limited [90]. J Pharm Technol. Twenty-four base case decision models were built, accounting for differences in the diagnostic workup, setting (inpatient vs outpatient) and geographic region. Incremental net benefits (difference of net benefits, with an incremental net benefit >0 indicating that penicillin allergy testing is cost-saving) obtained through use of fixed values were plotted against the percentage of simulations (obtained via probabilistic sensitivity analysis) identifying penicillin allergy testing as cost-saving. This study has also several strengths. Financial support. Skin testing and oral amoxicillin challenge in the outpatient allergy and clinical immunology clinic in pregnant women with penicillin allergy. 2 3 It is estimated, however, that only around 20% of those reporting penicillin allergy . Quantitative allergen-specific IgE test is indicated: Hospital statisticsbasic data of the hospitals and the prevention or rehabilitation facilities [in German]. We built decision models projecting whether penicillin allergy testing would be cost-saving. Further prospective follow-up studies are needed to more accurately assess the impact of delabeling patients claiming a penicillin allergy label. Thao V, Sharpe EE, Dholakia R, Ahn HH, Moriarty JP, Borah BJ, Gill MC, Theiler RN. In fact, for inpatients, our models only took into account that specific hospitalization and any possible readmission within the next month after discharge, ignoring potential savings in subsequent hospitalizations or in the use of ambulatory care. The Cost of Penicillin Allergy Evaluation - ScienceDirect.com Penicillin allergies are associated with inferior patient and antimicrobial stewardship outcomes. Does this child really have a penicillin allergy? In our decision models, penicillin allergy testing remained cost-saving even considering the additional quantification of specific immunoglobulin E (IgE). The health service perspective was adopted, considering costs with penicillin allergy tests, and with hospital bed-days/outpatient visits, antibiotic use, and diagnostic testing. Allergy testing at a Labcorp near you doi: 10.1016/j.jaip.2017.08.006. Decision Models Inputs and Respective Distributions. M, Arnold A, Sommerfield A, et al. Quantitative allergen-specific IgE test is indicated: To determine if a patient has elevated allergen-specific IgE antibodies; If specific allergic sensitivity is needed to allow immunotherapy to be initiated; When testing patients for agents that may potentially cause anaphylaxis; When evaluating patients who are taking medications (eg, long-acting antihistamines), which interfere with other testing modalities (eg, skin testing); If immunotherapy or other therapeutic measures based on skin testing results have not led to a satisfactory remission of symptoms; When patient is unresponsive to medical management where identification of offending allergens may be beneficial. bIn the base case scenario, we assumed that all patients with negative results were delabeled. Hospital healthcare Europe 2017. A reaction to penicillin during a childhood infection is unlikely to be a true allergy. Clipboard, Search History, and several other advanced features are temporarily unavailable. Sousa-Pinto Penicillin Allergy Assessment and Skin Testing in the Outpatient Studies performed in general populations identify that up to 5% of individuals claim to be allergic to penicillins, and this percentage often rises to >10% in studies assessing outpatients or inpatients [24]. Objective To evaluate the cost-effectiveness of penicillin allergy testing and appropriate antibiotic treatment (test then treat strategy) compared to usual care among pregnant women. Acknowledgments. Intern Med J. Therefore, it is not possible to causally prove that increased healthcare use among patients with a penicillin allergy label is necessarily because of such label.
