ABSTRACT
Objetivo Evaluar la precisión diagnóstica de los criterios empleados para detectar al paciente realmente portador de microrganismos multirresistentes (MMR). Diseño Estudio prospectivo, observacional de mayo de 2014 a mayo de 2015. Ámbito Unidad de cuidados intensivos polivalente. Pacientes Cohorte de pacientes ingresados de forma consecutiva que cumplían los siguientes criterios de aislamiento preventivo basados en el proyecto «Resistencia Zero»: hospitalización de más de 4 días en los últimos 3 meses («hospital»); antibioterapia durante una semana en el último mes («antibiótico»), pacientes institucionalizados o en contacto con cuidados sanitarios («institución o cuidado»); portador de MMR los últimos 6 meses («MMR previo»). Variables Variables demográficas, resultados de los cultivos obtenidos con presencia o no de MMR y tiempo de aislamiento. Se realizó un análisis multivariable con regresión logística múltiple entre cada uno de los factores de riesgo y el que el paciente fuera portador de MMR. Resultados Durante el periodo de estudio ingresaron 575 pacientes y cumplieron los criterios de aislamiento un 28%. De los 162 pacientes con criterios 51 (31%) eran portadores de MMR y de los que no cumplían criterios 29 (7%) sí que eran portadores. En el análisis multivariable la única variable asociada de forma independiente con el ser portador fue «MMR previo», con una OR 12,14 (IC 95%: 4,2434,77). Conclusiones El único criterio que se asoció de forma independiente con la capacidad de detectar los pacientes con MMR al ingreso en la UCI fue haber presentado un «MMR previo». (AU)
Objective To assess the diagnostic accuracy of the criteria used to detect patients carrying multiresistant microorganisms (MRMs). Design A prospective observational study was carried out from May 2014 to May 2015. Setting Polyvalent Intensive Care Unit. Patients A cohort of consecutively admitted patients meeting the following criteria for preventive isolation according to the Zero Resistance project: hospital length of stay>4 days in the last three months (hospital); antibiotherapy during one week in the last month (antibiotic); institutionalized patients or recurrent contact with healthcare (institution or care); MRM carrier in the last 6 months (previous MRM). Variables Demographic data, culture results and isolation time. A multivariate analysis was performed using multiple logistic regression between each of the risk factors and patient MRM carrier status. Results During the study period, 575 patients were admitted, of which 28% met the isolation criteria (162). Fifty-one (31%) were MRM carriers. Of the patients who did not meet the criteria, 29 (7%) were carriers. In the multivariate analysis, the only variable independently associated to carrier status was previous MRM, with OR=12.14 (95%CI 4.24-34.77). Conclusions The only criterion independently associated with the ability to detect patients with MRMs upon admission to the ICU was the existence of previous MRM. (AU)

OBJECTIVE: To assess the diagnostic accuracy of the criteria used to detect patients carrying multiresistant microorganisms (MRMs). DESIGN: A prospective observational study was carried out from May 2014 to May 2015. SETTING: Polyvalent Intensive Care Unit. PATIENTS: A cohort of consecutively admitted patients meeting the following criteria for preventive isolation according to the "Zero Resistance" project: hospital length of stay>4 days in the last three months ("hospital"); antibiotherapy during one week in the last month ("antibiotic"); institutionalized patients or recurrent contact with healthcare ("institution or care"); MRM carrier in the last 6 months ("previous MRM").

A multivariate analysis was performed using multiple logistic regression between each of the risk factors and patient MRM carrier status. RESULTS: During the study period, 575 patients were admitted, of which 28% met the isolation criteria (162). Fifty-one (31%) were MRM carriers. Of the patients who did not meet the criteria, 29 (7%) were carriers. In the multivariate analysis, the only variable independently associated to carrier status was "previous MRM", with OR=12.14 (95%CI 4.24-34.77).
