Abstract
Hospital- acquired infections (HAIs) are among the major causes of excess morbidity and mortality among hospitalized patients. They are a significant burden both for the patient and for public health, as they cause an enormous excess in healthcare costs.
Hospital acquired infections occur worldwide and affect both developed and developing countries. The highest prevalence rates of HAI were observed in intensive care units and surgery wards.
Resistance to antibiotics (especially the appearance of methicillin resistant Staphylococcus aureus) is one of the leading characteristics of the microbial agents of HAI.
The hospital acquired infection rate in patients in a facility is an indicator of quality and safety of care. A reduction in HAI rate is well documented following the implementation of an infection control program that includes surveillance.
The frequency of such infections, and the agents and their resistance rates should be identified in order to better control infection. Identifying factors that influence hospital acquired infection risk has the potential to help direct resources to decrease the incidence of these infections.
