Abstract
Background: Device-associated health care-associated infections (DA-HAIs) are a major threat to patient safety, particularly in the Intensive Care Unit (ICU). The aim of this study was to evaluate the effectiveness of a bundle of infection control measures to reduce DA-HAIs in the ICU of a General Hospital in the Republic of Cyprus, over a three-year period.
Methods: We studied 599 ICU patients with length of stay (LOS) for at least 48 hours. Our prospective cohort study was divided into three surveillance phases. VAP, CLABSI, and CAUTI incidence rates, LOS and mortality were calculated before, during and after the infection prevention and control program.
Results: There was a statistically significant reduction in the number of DA-HAI events during the surveillance periods, associated with DA-HAIs prevention efforts. In 2015 (prior to program implementation), the baseline DA-HAIs instances were 43: 16 VAP (10.1/1000 Device Days), 21 (15.9/1000DD) CLABSIs and 6 (2.66/1000DD) CAUTIs, (n=198). During the second phase (2016), CLABSIs prevention measures were implemented and the number of infections were 24: 14 VAP (12.21/1000DD), 4 (4.2/1000DD) CLABSIs & 6 (3.22/1000DD) CAUTIs, (n=184). During the third phase (2017), VAP and CAUTI prevention measure were again implemented and the rates were 6: (3 VAP: 12.21/1000DD), 2 (1.95/1000DD) CLABSIs & 1 (0.41/1000DD) CAUTIs, (n=217). There was an overall reduction of 87% in the total number of DA-HAIs instances for the period 01/01/15 to 31/12/17.
Conclusions: The significant overall reduction in DA-HAI rates, indicates that a comprehensive infection control program can affect DA-HAI rates.
