Objectives: The inconsistent application of hygiene measures by healthcare workers accounts largely for the epidemic dissemination of nosocomial infections (NI); our aim is to know the prevalence of NI on an Intensive Care Unit (ICU) and to assess the influence of a hygiene promotion programme in the rate of NI.

Patients and Methods: The efficacy of a hygiene promotion programme to prevent NI was assessed in our ICU during 1-year period; initially, a prospective and observational study of NI cases on the ICU during a 6 month period (PI) was done; epidemiological and clinical variables as well as information about risk factors related to NI were assessed. These data were compared to those corresponding to a second prospective and observational study period (PII) during which a health-workers hygiene promotion programme was established. Education of hospital staff was an essential component of the programme aimed to predispose healthcare workers to adopt hand hygiene behaviour (poster campaign and educational meetings and handouts), reinforce and enable the behaviour (provision of an alcohol hand rub beside each patient's bedside). Antibiotic policies and ICU staff were the same during the two periods.

Results: 395 patients were assess during PI and 411 in PII; there were not statistically significant differences on epidemiological or clinical variables during the two periods; there was no difference in risk factors related to NI (underlying conditions, severity at admission, rate of urgent surgeries, invasive techniques, ICU length of stay, mechanical ventilation, etc.). The rate of infection in PI was 26% and 16% in PII (p < 0.05). Hand-washing rate was significantly higher in PII than in PI (previous to patient care: 45% and 35% respectively and post patient care: 63% and 51%, respectively)

Conclusion: Patient's features during PI and PII were similar; there was a significant increase in ICU staff hand-hygiene compliance during the educational phase; the incidence rates of NI during the pre-programme period (PI) were significantly higher than during the programme period.
