National Nosocomial Infection Surveillance System- based study in north eastern of Iran

HAIs are a major public health problem that occurs among about 10% hospitalized patients. Nosocomial infections increase mortality and morbidity andprolonged hospital stay. They impose considerable costs to the health care system. This study was conducted in order to aware of the present status of nosocomial infections and comparison of our data to other studies.
This prevalence study of HAI was carried out in 26 hospitals using a protocol updated yearly in Mashhad, Iran. The CDC NNIS system was used to define 4 nosocomial infections. All patients admitted to the hospitals during a 1-year period (March 1, 2015-February 30, 2016). Data was gathered from hospitals was in INIS (Iranian nosocomial infectionsurveillance) software.
The overall prevalence rates of HAI in our study were 0.8% among the hospitals.
Most frequent HAI had been PNEU, followed by UTI. The highest prevalence rate was observed in 15 to 65 years old. (56.26 %) and most of them were SSI. The most frequently isolated micro-organism was acintobacter. Most infections have occurred in winter and most of them is pneumonia. A total of 4988 pathogens were isolated, 30.33 percent of infections were confirmed by clinical diagnosis and 69.66 percent with positive culture.
These findings emphasize the need for appropriate control programs to develop screening, labelling and isolation precautions and created awareness regarding the magnitude of the problem of nosocomial infections and generated interest for systematic control efforts.
