ABSTRACT
INTRODUCCIÓN: La ola pandémica de COVID-19 de marzo de 2020 mermó las medidas de control de infección en las UCI. Se describe un brote polimicrobiano, sus posibles factores de riesgo, relación con la COVID-19 y medidas que facilitaron su control. MÉTODOS: estudio observacional longitudinal retrospectivo. RESULTADOS: se estudiaron 149 pacientes, 23 casos presentaron microorganismos de interés, 9 más de uno. Se aislaron 15 Klebsiella pneumoniae BLEE, 5 KPC, 8 hongos filamentosos y 5 bacilos gramnegativos no fermentadores. La tasa de ataque fue de 0,154 siendo superior para ingresos COVID-19 (0,262) frente a otros motivos (0,015), con una diferencia de 0,247 (0,148-0,345; p < 0,001). Se implementaron medidas de control sobre los riesgos detectados. CONCLUSIÓN: ser paciente COVID-19 se asoció con mayor riesgo de ser caso, consideramos como posibles desencadenantes el mayor contacto requerido con equipos de protección y la pérdida temporal de control sobre la multirresistencia, tanto de información como de competencia
INTRODUCTION: The pandemic wave of COVID-19 in March 2020 undermined compliance with infection control measures in ICUs. A polymicrobial outbreak, its possible risk factors, relationship with COVID-19 and measures that facilitated its control are described. METHODS: retrospective longitudinal observational study. RESULTS: 149 patients were studied, 23 cases presented microorganisms of interest, 9 more than one. 15 Klebsiella pneumoniae ESBL, 5 KPC, 8 filamentous fungi and 5 non-fermenting gram-negative bacilli were isolated. The attack rate was 0.154, being higher for patients admitted for COVID-19 (0.262) compared to other reasons (0.015), with a difference of 0.247 (0.148-0.345; p < 0.001). Control measures were implemented on the risks detected. CONCLUSION: being a COVID-19 patient was associated with a higher risk of being a case, we consider as possible triggers the greater contact required with protective equipment and the temporary loss of control over multidrug resistance, both of information and of competence
