Four country healthcare associated infection prevalence survey 2006: risk factor analysis

Point prevalence surveys are useful in detecting changes in the pattern of healthcare-associated infection (HCAI). In 2004 the Hospital Infection Society was asked to conduct a third national. prevalence survey, which included England, Wales, Northern Ireland and the Republic of Ireland. A similar but not identical survey was carried out in Scotland. Data were collected on standardised forms using Centres for Disease Control. and Prevention definitions. This report considers associations with a wide range of risk factors for all HCAI and for four main categories. The overall prevalence rate of HCAI was 7.6% and increased significantly with age. All risk factors considered were associated with highly significantly increased risk of HCAI, except recent peripheral IV catheter and other Madder instrumentation use. Primary bloodstream infection (PBSI) was associated with antibiotic, central, intravenous catheter and parenteral nutrition use. Pneumonia was associated with antibiotic, central catheter, parenteral nutrition use, mechanical. ventilation and current peripheral catheter use. Surgical, site infection was associated with recent surgery, antibiotic and central catheter use, mechanical, ventilation and parenteral nutrition.
