BACKGROUND AND OBJECTIVE: Being labeled as allergic to penicillin (unverified ß-lactam allergy) can result in patients receiving broader-spectrum antibiotics than necessary that may be more toxic, less effective, and/or more expensive than alternative options. Objective: We aimed to evaluate the real costs of evaluating ß-lactam allergy. METHODS: We performed a prospective real-life observational study designed to evaluate all adult patients who consulted for suspected ß-lactam allergy over a 1-year period. Direct and indirect costs were systematically recorded. Direct health costs were calculated based on the number of visits and all additional and diagnostic tests performed, direct nonhealth costs based on the number of visits and the distance from their homes to the Allergy Department, and indirect costs based on absenteeism. RESULTS: A total of 296 patients with suspected allergy to ß-lactams were evaluated in our outpatient clinic from June 1, 2017 to May 31, 2018. Total direct health care costs were 28 176.70, with a mean (SD) cost of 95.19 (37.20). Direct nonhealth costs reached 6551.73, that is, 22.13 (40.44) per patient. Indirect health costs reached 20 769.20, with a mean of 70.17 (127.40). In summary, the total cost was 55 497.63, that is, a cost per patient of 187.49 (148.14). CONCLUSIONS: When all possible costs are taken into account, the evaluation of ß-lactam allergy is not expensive and can reduce future expense arising from unnecessary use of more expensive and less effective antibiotics.

BACKGROUND: Being labeled as allergic to penicillin (unverified beta-lactam allergy) can result in patients receiving broader-spectrum antibiotics than necessary that may be more toxic, less effective, and/or more expensive than alternative options. OBJECTIVE: We aimed to evaluate the real costs of evaluating beta-lactam allergy. METHODS: We performed a prospective real-life observational study designed to evaluate all adult patients who consulted for suspected beta-lactam allergy over a 1-year period. Direct and indirect costs were systematically recorded. Direct health costs were calculated based on the number of visits and all additional and diagnostic tests performed, direct nonhealth costs based on the number of visits and the distance from their homes to the Allergy Department, and indirect costs based on absenteeism. RESULTS: A total of 296 patients with suspected allergy to beta-lactams were evaluated in our outpatient clinic from June 1, 2017 to May 31, 2018. Total direct health care costs were (Euro)28 176.70, with a mean (SD) cost of (Euro)95.19 (37.20). Direct nonhealth costs reached (Euro)6551.73, that is, (Euro)22.13 (40.44) per patient.

INTRODUCCIÓN: Un diagnóstico no verificado de alergia a la penicilina o a los betalactámicos (BL) conlleva que los pacientes reciban antibióticos de amplio espectro, que pueden ser más tóxicos, menos efectivos, y/o de mayor coste. OBJETIVO: Evaluar los costes reales de un estudio de alergia a los betalactámicos. MÉTODOS: Se diseñó un estudio observacional prospectivo en condiciones de práctica clínica habitual en el que se evaluaron todos los pacientes adultos que consultaron por sospecha de alergia a BL durante un año. Los costes directos e indirectos se recogieron sistemáticamente. Los costes directos sanitarios se calcularon teniendo en cuenta el número de visitas y todas las pruebas diagnósticas realizadas; en los costes directos no sanitarios se consideraron el número de visitas y los kilómetros desde el domicilio hasta el Servicio de Alergología; en los costes indirectos se evaluó el absentismo. RESULTADOS: Se evaluaron 296 pacientes remitidos desde el 1 de junio de 2017 hasta el 31 de mayo de 2018. Los costes directos totales sanitarios fueron 28.176,70 (Euro): coste medio (desviación estándar, DS) de 95,19 (Euro) (37,20). Los costes directos no sanitarios alcanzaron, 6.551,73: coste medio 22,13 (40,44). Los costes indirectos fueron 20.769,20 (Euro): coste medio (DS) 70,17 (127,40). En resumen, la cantidad total fue de 55.497,63 (Euro), lo que supone un coste medio de 187,49 (Euro) (148,14). CONCLUSIONES: Considerando todos los costes posibles, la evaluación de la alergia a betalactámicos no es cara y puede ahorrar gastos futuros debido a una utilización innecesaria de antibióticos más caros y menos efectivos
