ABSTRACT Objetivo. Determinar la incidencia de bacteriemia relacionada con catéter y neumonía asociada a ventilador en niños hospitalizados. Material y métodos. Estudio prospectivo. En el servicio de Pediatría del Hospital General Regional (HGR) No 1 del Instituto Mexicano del Seguro Social (IMSS), de Durango, México, durante 18 meses, de enero de 1999 a junio del 2000, se implementó un sistema de vigilancia epidemiológica activa para identificar episodios de neumonía y bacteriemia nosocomial de acuerdo a las definiciones operacionales de la Norma Oficial Mexicana (NOM). A los pacientes hospitalizados que por su patología requirieron de ventilación mecánica o de catéter intravenoso central se les hizo seguimiento desde el primer día de exposición hasta la detección del episodio de infección o su retiro. Se efectuaron hemocultivos y cultivos de aspirado traqueal. Se calcularon tasas de incidencia para la neumonía asociada a ventilador y de bacteriemia/sepsis por 1 000 días de exposición con sus respectivos intervalos de confianza al 95%. También se presenta la tasa mensual de la infección por días de exposición por medio de gráficas de control estadístico. Resultados. Se identificaron 47 episodios de bacteriemia/sepsis relacionada con catéter y 44 de neumonía asociada a ventilador. La tasa de incidencia de neumonía fue de 28 eventos por 1 000 días de exposición a ventilador y la de bacteriemia/sepsis fue de 26 eventos por 1 000 días de exposición a catéter intravenoso central. Los microrganismos gram positivos (61.11%) predominaron sobre los gram negativos (38.88%). Conclusiones. Este estudio documentó tasas de neumonía y bacteriemia en niños, sustancialmente más elevadas que en otros informes, lo que hace necesario establecer lineamientos para la prevención de infecciones en niños con catéteres intravasculares y sobre los cuidados que requieren los niños sometidos a ventilación mecánica.

    ABSTRACT: Health-care-associated infection is the most frequent result of unsafe patient care worldwide, but few data are available from the developing world. We aimed to assess the epidemiology of endemic health-care-associated infection in developing countries. We searched electronic databases and reference lists of relevant papers for articles published 1995-2008. Studies containing full or partial data from developing countries related to infection prevalence or incidence-including overall health-care-associated infection and major infection sites, and their microbiological cause-were selected. We classified studies as low-quality or high-quality according to predefined criteria. Data were pooled for analysis. Of 271 selected articles, 220 were included in the final analysis. Limited data were retrieved from some regions and many countries were not represented. 118 (54%) studies were low quality. In general, infection frequencies reported in high-quality studies were greater than those from low-quality studies. Prevalence of health-care-associated infection (pooled prevalence in high-quality studies, 15·5 per 100 patients [95% CI 12·6-18·9]) was much higher than proportions reported from Europe and the USA. Pooled overall health-care-associated infection density in adult intensive-care units was 47·9 per 1000 patient-days (95% CI 36·7-59·1), at least three times as high as densities reported from the USA. Surgical-site infection was the leading infection in hospitals (pooled cumulative incidence 5·6 per 100 surgical procedures), strikingly higher than proportions recorded in developed countries. Gram-negative bacilli represented the most common nosocomial isolates. Apart from meticillin resistance, noted in 158 of 290 (54%) Staphylococcus aureus isolates (in eight studies), very few articles reported antimicrobial resistance. The burden of health-care-associated infection in developing countries is high. Our findings indicate a need to improve surveillance and infection-control practices. World Health Organization.

    ABSTRACT: Introduction Nosocomial infection is a frequent complication in neonatal intensive care units (NICUs) attending patients who require lengthy hospitalization and frequent invasive techniques. Patients and methods This study is part of a prospective surveillance program for nosocomial infection in Spain. All patients admitted to NICUs between June 1999 and March 2005 were observed. CDC criteria were used as the standard definition for nosocomial infection. Results A total of 1236 neonates (58% male) were admitted during the surveillance period, involving 19,420 days in the NICU. The average birth weight was 1947.6 ± 1009.5 g and average gestational age was 32.9 ± 5.4 weeks. The most frequent associated pathology was respiratory distress (23.06%). A total of 316 nosocomial infections were diagnosed in 226 neonates, 76.7% affecting premature neonates (< 1500 g). The most frequent location was bacteremia (56.3%), and there was a predominance of coagulase-negative staphylococci (46.05%). Gram-negative microorganisms were isolated in 32.1% of the cases (Escherichia coli and Pseudomonas aeruginosa were the most frequent pathogens). Overall incidence of nosocomial infection was 25.6%. Overall mortality was 6.6%, with higher mortality in the group with nosocomial infections (8.7%). Conclusions Nosocomial infection rates are acceptable, with a typical epidemiological pattern for these units. Presence of a central catheter increased the risk. A program to promote proper hand washing should be considered. We do not recommend a continuing surveillance strategy in these units.
