Hospital-acquired infections (HAIs) are critical and mostly preventable complications that occur in hospitalized patients. Incidence and prevalence surveillance provides tools to prevent and manage the burden of HAIs. Annual point prevalence surveys (PPS) have been performed in the Turku University Hospital from 2007 to 2017 and incidence since 1982.

PPS was performed in a Finnish tertiary care hospital with 747 beds. The objectives were to assess the magnitude and characteristics of HAIs. A PPS was conducted in each March from 2007 to 2017 to estimate HAI prevalence and associated risk factors.
HAI was found in 936 of 7670 patients (12.2 %). 91% of HAIs started during the current hospital stay. The most frequent HAIs were pneumonia (PPS 26% versus incidence 22%), surgical site infections (PPS 21% versus incidence 21%) and bloodstream infections (PPS 20% versus incidence 20%). The prevalence of HAI was most frequent in the intensivecareunits. On the day of the PPS, 19% of study patients had urinary catheter,11% centralvenous catheter, and 2% received mechanicalventilation as a risk factor for HAI.

The PPS showed that the long-term distribution of HAIs were strikingly similar in PPSs and in incidence surveys, indicating that incidence survey is as reliable method for HAI surveillance as PPS. These two methods are complementary to each other and increase the capturing of all HAIs. More primary prevention efforts are necessary to address HAIs associated to prevent surgical site infections and with the use of invasive devices.
