Staphylococcus aureus has become one of the leading causes of healthcare-associated infections (HAIs) and has been responsible for increasingly severe diseases in recent years. This study analyzed S. aureus-related HAIs in general wards and intensive care units (ICUs) in a medical center located in northern Taiwan from 2004 to 2008. We evaluated the total S. aureus infection rate, overall density of infection, density by infection site, characteristics of infected patients, and risk factors for HAI. The results showed that the mean rates of S. aureus infection in general wards and ICUs in the 5-year study period were 0.38% and 0.97%, respectively. The most frequent site of infection, in both general wards and ICUs, was the bloodstream. There were no significant differences in sex or age of the infected patients. Patients in ICUs had significantly higher rates of cardiovascular diseases and diabetes, and a larger number of ICU patients were bedridden for a long time (p＜0.05). The frequency of invasive medical procedures, including peripheral and central venous catheterization, endotracheal intubation, tracheotomy, urinary catheterization, ventilator support, and total parenteral nutrition (p＜0.0001), in ICU patients was also higher. Since S. aureus can be transmitted from the hands of healthcare workers, the most effective method to control S. aureus infection is to follow standard aseptic procedures while performing medical procedures, especially during invasive catheterization. Strict adherence to hand hygiene is also recommended. Removal of catheters as early as possible and controlled use of antibiotics are also important factors for containing S. aureus-related HAIs.
