Frequency of Nosocomial Pneumonia in ICUs of Hospitals of Hamadan University of Medical Sciences

Nosocomial pneumonia is the most prevalent causes of hospital-acquired infection in intensive Care Units (ICU). The purpose of this research was to detect the frequency and predisposing factors of nosocomial pneumonia in ICUs of hospitals of Hamadan University of medical sciences. In this cross sectional study, 353 patients that were hospitalized in ICUs of Hamadan hospitals (Besat and Ekbatan) were investigated. In the case of nosocomial pneumonia some variables including connecting until affection, the period of hospitalization in ICU until affection will were recorded for these patients. χ2 test and Fisher exact test were used for data analysis. 36 people (10.2%) of hospitalized patients in ICUs were affected to nosocomial pneumonia. The average age of studying patients was 51.2 ± 21.9 years old, in which the most affected people (28%) were older than 65 years old. 44.5% of patients with nosocomial pneumonia were affected about 2-5 days after hospitalization in ICU. 66.5% of these patients (24 patients) had ventilator associated pneumonia(VAP) after connecting to ventilation device. Considering to frequency and predispose of nosocomial pneumonia in this study, it's necessary to pay more attention to the patients whom are exposed to hospital–acquired infections. It is also recommended that all unnecessary intervening actions for the patients in ICU should be avoided. In the case of necessity for mechanical ventilation and for reducing the onset of pneumonia, it is necessary to consider all sanitary actions.
