Programa de optimización de antibioterapia en infección urinaria por cepas multirresistentes en el servicio de urgencias / Antimicrobial stewardship program in urinary tract infections due to multi resistant strains in the emergency department

Introducción. Las infecciones urinarias (ITU) son un mo tivo frecuente de asistencia a los servicios de urgencias hospi talarias (SU), siendo cada vez más frecuente el aislamiento de cepas multirresistentes. El presente trabajo pretende evaluar el impacto de un programa multidisciplinar de optimización de antibioterapia en pacientes con ITU causada por bacterias mul tirresistentes atendidas desde el SU. Material y métodos. Estudio descriptivo de la puesta en marcha de un programa en el que participaron los servicios de urgencias, microbiología y farmacia. El tratamiento antibiótico de los pacientes que consultaron urgencias con urinocultivos positivos para bacterias multirresistentes fue revisado al alta por el equipo multidisciplinar. En aquellos pacientes con tra tamiento inapropiado se contactó con los médicos y/o farma céuticos del siguiente nivel asistencial o con los propios pa cientes en el caso de alta a domicilio. Se evaluó el impacto del programa sobre las nuevas consultas a urgencias a 30 días en comparación con los resultados obtenidos de la práctica habi tual en tres meses previos a la intervención. Resultados. Durante el año de implantación se revisaron 2.474 urinocultivos de pacientes con ITU, 537 (21,7%) causa das por bacterias multirresistentes. El tratamiento empírico al alta de urgencias fue inapropiado en 287 (53,4%) pacientes, realizando modificaciones del tratamiento en 232 de ellos. 73 pacientes (19,3%) reconsultaron el SU a los 30 días del alta, siendo este porcentaje inferior a los resultados obtenidos en los tres meses previos a la intervención (27,9%; p=0,031), sin encontrar diferencias significativas en el porcentaje de nuevas visitas asociadas a infecciones urinarias. Conclusión (AU)

Introduction. Urinary tract infections (UTI) are a fre quent reason for attendance at emergency department (ED). The present study evaluates the impact of a multidisciplinary program for the optimization of antibiotic therapy in patients with UTI caused by multi-drug resistant bacteria treated from the hospital ED. Material and methods. Descriptive study of the imple mentation of a program in which emergency, microbiology and pharmacy departments participated. Antibiotic treatment of the patients who consulted the ED with positive urine cul tures caused by multidrug-resistant bacteria was reviewed up on discharge. In those patients with inappropriate treatment, doctors and/or pharmacists of the next level of healthcare or patients in the case of home discharge were contacted. The impact of the program was evaluated based on new visits to the ED at 30 days after discharge, compared with the results obtained from the usual practice three months prior the in tervention. Results. During the first year, 2,474 urine cultures of pa tients with UTI were reviewed, 533 (21.7%) were caused by multidrug-resistant bacteria. Empirical treatment was inap propriate in 287 (53.4%), making treatment modifications in 243 of them. 73 (19.3%) patients returned to the ED 30 days after discharge, being lower than the results obtained in the three months prior intervention (27.9%; p=0.031), without significant differences in new visits associated with UTI. Conclusion. The implementation of a multidisciplinary program focused on multidrug resistant UTI at discharge form ED correct antibiotic therapy in a large number of patients, be ing a potentially tool to reduce the number of new ED visits (AU)

PREDICTION OF MULTIDRUG-RESISTANT BACTERIA IN URINARY TRACT INFECTIONS IN THE EMERGENCY DEPARTMENT.

BACKGROUND: Urinary tract infections (UTI) due to multidrug-resistant bacteria are a frequent reason for visiting the emergency department (ED). OBJECTIVES: The aim of this study was to evaluate the applicability of a predictive model of infection by multidrug-resistant microorganisms in UTIs treated in an ED. METHODS: This is a retrospective observational study. Adult patients admitted to an ED with a diagnosis of UTI and positive urine culture were included. The main objective was to evaluate the area under the curve of the receiver operating characteristic (AUC-ROC), the scale proposed by González-del-Castillo, considering infection by a resistant pathogen as the dependent variable and the scale score of the predictive model used as the independent variable. RESULTS: The study included 414 patients with UTIs, 125 (30.2%) of which were caused by multidrug-resistant microorganisms. A total of 38.4% of patients were treated with antibiotics during the previous 3 months and a multidrug-resistant pathogen was isolated from 10.4% of the total during the previous 6 months. The AUC-ROC of the scale for predicting UTIs due to multidrug-resistant microorganisms was 0.79 (95% confidence interval 0.76-0.83), the optimal cut-off point being 9 points, with a sensitivity of 76.8% and a specificity of 71.6%. CONCLUSIONS: The use of the predictive model evaluated is a useful tool in real clinical practice to improve the success of empirical treatment of patients presenting to the ED with a diagnosis of UTI and positive urine culture pending identification.
