Nosocomial infections in an Iranian educational hospital: an evaluation study of the Iranian nosocomial infection surveillance system.

We reported ICU and Acinetobacter (spp.) as the most affected ward and most common agent involved in recorded NIs respectively. The rate of NI in the study hospital was exceptionally low when compared to its counterparts in a few other developed countries. The INISS needs to be further evaluated with regard to the completeness and representativeness of the surveillance system. Also, we need to evaluate the adherence to the INISS guidelines among staff and physicians in reporting the NIs.
