Device-associated Nosocomial Infections (DAI) Rates in Medical-Surgical Intensive Care Unit (MS-ICU), in a Single Brazilian Tertiary Teaching General Hospital – One Decade Comparative Study

Background: <>The rates of health care-associated infections in developing contries are 3 to 5 times higher than international standar.

Objective: <>To measure the incidence of DAI in a C-CR-ICU and compare with US-CDC/INICC NNIS data.

Methods: <>We used our one decade prospective surveillance NNIS CDC definitions data. Our Hospital is 800 bed tertiary hospital and of 7 adult ICUs, three MS-ICU with total 48 beds were evaluated.

Results: <>During january/99 to december/2008 for an aggregate 105044 patients days, acquired 1693 DAI, at an overall rates of 16,11 DAI per 1000 ICU days. Comparing with CDC/INNIC respectively (all per 1000 devides/days) 2.4/8.92 central venous catheter (CVC) - associated bloodstream Infections (ABIs), 3.6/19.8 ventilator-associated pneumonia (VAP), 3.4/6.49 Urinary catheter (UC) -associated urinary tract infection (AUTI); we found the following data: CVCABIs 1.66, VAP 17.55, UCAUTI 3.87. Our results confirm the success of the control program of CVCABIs during 10 years. The result of UCAUTI was similar than CDC. Nevertheles, VAP is little better than INNIC, but almost five times more than CDC data.

Conclusions: <>Our infection control program must be aimed VAP prevention.
