ABSTRACT
OBJECTIVE: To estimate quality healthcare indicators in an intensive care unit (ICU). METHODS: A prospective observational study was conducted on all patients referred to the medical ICU of Ramón y Cajal hospital (Madrid) for more than 48 hours, from January 1 2008 to December 31 2009. RESULTS: A total of 503 patients were included, of whom 7.4% developed a healthcare-associated infection (HAI) attributable to their stay in the ICU. The median length of stay was 5 days. A ventilator-associated pneumonia (VAP) was observed in 1.9% of patients, with a VAP rate of 3.8 per 1,000 ventilator-days. A catheter-associated urinary tract infection (CAUTI) was found in 3.6% of the patients, with a CAUTI rate of 4.5 per 1,000 catheter-days. The cumulative incidence of central line-associated bloodstream infection (CLABSI) was 1.8%, with a CLABSI rate of 2.2 per 1,000 central line-days. CONCLUSIONS: Our results are similar to those of other studies using the same methodology. An HAI surveillance system is a key factor for implementing a healthcare quality improvement system. The obtained indicators allow intra-comparison over time and with other similar hospitals, the monitoring of infection control measures, and thus an effective improvement in healthcare quality and patient safety.
