[Prevalence of nosocomial infections in University Hospital of Habana]. / Prevalencia de infección nosocomial en hospitales universitarios de La Habana, Cuba.

OBJECTIVE: Determine nosocomial infection (NI) prevalence in seven University Hospitals of Havana. METHOD: A cross sectional survey was carry out in university hospital with more than 100 beds. Presence of NI was determined by an active screening procedure in all patients admitted in hospitals. Technical statistics of frequency distribution was used. Rates of NI were estimated for each hospital and in the special case of procedure, Odds Ratio and its confidence interval at 95 % were calculated (CI 95 %). RESULTS: Prevalence of NI was 9.2 %. The most frequent localization were: cardiovascular system (55 patients), surgical site (50 patients) and urinary tract (42 patients ). The 19.7 % of studied patient showed intravascular device. All patients showed NI associated with procedures, the highest intensity was association with an endotracheal tube (OR 7.83, IC 95 % 3.32-11.52). CONCLUSION: Nosocomial infections in this hospital is a serious health problem; it is necessary to focus our medical work in this regard for the prevention and control of NI.

Prevalencia de infección nosocomial en hospitales universitario de La Habana, Cuba / Prevalence of nosocomial infections in university hospital of Havana

Objetivo: Determinar la prevalencia de infección nosocomial (IN) en siete Hospitales Clínico Quirúrgicos de Ciudad de La Habana. Método: Realizamos un estudio descriptivo de corte transversal de los hospitales universitarios con número de camas superior a 100. La presencia de IN, se determinó mediante la realización de pesquizaje activo en la totalidad de los pacientes ingresados. Se utilizó la técnica estadística de análisis de distribución de frecuencias. Fueron calculadas tasas de IN, por hospital y servicio de atención. También se calculó Odds Ratio puntual y por intervalos. Resultados: La prevalencia global de IN resultó ser de 9,2 por cada 100 pacientes. Las localizaciones más frecuentes correspondieron a: el sistema cardiovascular (55 casos), el sitio quirúrgico (50 casos) y el tracto urinario (42 casos). El 19,7 % de los pacientes estudiados, tenían algún dispositivo intravascular colocado. Todos ellos fueron encontrados asociados a la presencia de infección nosocomial. La mayor intensidad resultó ser con la entubación endotraqueal (OR 7.83 IC 95 % 3,32-11,52). Conclusión: La prevalencia de infecciones nosocomiales en los Hospitales Clínico Quirúrgicos de Ciudad de la Habana hacen necesario fortalecer las actividades de prevención y control, con especial énfasis en su vigilancia
