Abstract (English):	Objective: To evaluate the impact of a multifaceted antimicrobial stewardship intervention on potentially unnecessary antibiotic prescribing. Material and methods: Before and after quality control study carried out in three different settings--general practice, out-ofhours services, and nursing homes--in Spain. Healthcare professionals (both doctors and nurses) self-registered common infections using a specific template for each setting before (2022) and after (2023) receiving a 5-hour intervention on prudent antibiotic use. Results: Eighty-nine professionals participated in the first registration (48 in general practice, 23 in out-of-hours services, and 15 in nursing homes), with 71 (79.8%) completing the intervention and second registration. Potentially unnecessary antibiotic prescriptions were 68.5%, 41.7%, and 77.7% in the first registration, respectively, and 61.4%, 34.8%, and 86.8% after the intervention, showing reductions of 10.4% in general practice and 16.5% in out-of-hours services, and an 11.7% increase in nursing homes, albeit without statistically significant differences. Conclusions: The study found that this intervention slightly improved antibiotic use, with minimal impact, but worsened in nursing homes. [ABSTRACT FROM AUTHOR]
Abstract (Spanish):	Objetivo: Evaluar el impacto de una intervención multifacética en la prescripción antibiótica potencialmente innecesaria. Material y métodos: Estudio de calidad antes-después realizado en tres ámbitos distintos--medicina general, servicios de urgencias de atención primaria y residencias geriátricas--en España. Los profesionales sanitarios (tanto médicos como personal de enfermería) registraron infecciones comunes utilizando una plantilla específica para cada entorno antes (2022) y después (2023) de recibir una intervención de 5 horas sobre prescripción prudente de antibióticos. Resultados: 89 profesionales participaron en el primer registro (48 en medicina general, 23 en urgencias y 15 en residencias), de los cuales 71 (79,8%) completaron la intervención y el segundo registro. La prescripción antibiótica potencialmente innecesaria fue 68,5%, 41,7% y 77,7% respectivamente en el primer registro, y 61,4%, 34,8% y 86,8% después de la intervención, mostrando reducciones del 10,4% en medicina general y 16,5% en urgencias y aumento del 11,7% en residencias, sin diferencias estadísticamente significativas. Conclusiones: La intervención mejoró ligeramente la prescripción antibiótica después de la intervención, con mínimo impacto. En residencias geriátricas, su calidad empeoró. [ABSTRACT FROM AUTHOR]
