Hospitals in Taiwan have routinely conducted surveillance on healthcare-associated infections(HAIs) for years. In this article, we introduced the timeline of changes in HAI definitions, presented results of a survey conducted in 2012, and described the mistakes usually occurred in medical centers and regional hospitals in defining a patient as device-associated infection case or counting device-days. The results demonstrated that 79%, 83% and 76% hospitals identified central line-associated bloodstream infection(CLABSI), ventilator-associated pneumonia,and catheter-associated urinary tract infection(CAUTI) cases respectively based on the criteria conformed to Taiwan Nosocomial Infections Surveillance(TNIS) definition. The most common inconsistency found is to classify a CLABSI case relying on tip culture result, and to count device-days according to the number of central lines on patients. This survey provided useful information for developing strategies in surveillance refinement and data quality improvement.
