[Comparative study of three selective methods for nosocomial pneumonia surveillance in non-critical adult patients].

Abstract：

BACKGROUND AND OBJECTIVE:Among nosocomial infections, pneumonia is one of the most important ones due to the mortality, morbidity and the increase of costs that it causes. The implementation of a cost-effective surveillance system for these infections is a challenge for hospitals. The objective of this work was to evaluate three selective methods of surveillance for nosocomial pneumonias in non-critical adult patients. PATIENTS AND METHOD:A prospective surveillance of nosocomial pneumonias was carried out during 4 months in an university hospital of the Valencian Community, by means of three methods based on reports of chest x-ray, consumption of several antibiotics and health-care workers' liaison. Subsequently, possible cases were confirmed through revision of patient's charts, comparing each method with the reference one. RESULTS:Of 541 possible cases of pneumonia, 27 were confirmed. The cumulative incidence was 3.67 cases/1,000 admissions and the incidence density was 5.9 cases/10,000 patient-days. The method with the highest sensitivity was that dealing with the consumption of antibiotics (85.2%), followed by x-rays (70.4%). The method based on the personnel's liaison had 99.4% specificity, while that of x-rays was 75.5%. Negative predictive values were above 95% for the three methods. CONCLUSIONS:A surveillance system for nosocomial pneumonia based on reports of chest x-rays may be very efficient, providing the necessary information to program and to evaluate the prevention and control activities for these infections in the hospital.
