INFECTION, PATHOLOGY
A data extraction tool has been developed and piloted in REDCap®. This tool was adapted from a previous multi-centre point prevalence study (1). The researcher responsible for collecting the data will be trained in the use of the survey instrument to extract relevant data pertaining to the intervention and relevant outcomes. After reviewing medical records, pathology and microbiology databases, the researcher will determine if the patient has a HAI. The determination of a HAI will be undertaken through an algorithm applying the HAI definitions in the ECDC protocol (16). Data on each HAI identified will be consistent with the ECDC protocol. The attribution of a HAI to a ward will be determined through the use of a 48-h time frame, i.e. the infection symptom onset must occur > 48 h after admission to the ward, for it to be attributable to the ward. If a patient is transferred to a ward and a HAI is identified within 48 h of transfer, it will be attributed to the previous ward. An interrater reliability assessment will be independently undertaken to validate the accuracy of HAI determinations (1).
