Step 2 : Recruiting and enhancing the capacity of the Core Working Group The 14 members of CWG were representatives of all HCWs in three MICUs. After raising their awareness by discussing the current situation of CAUTI problems in their units, they expressed their willingness to be co-researchers and the need to solve these problems. To enhance their ability to be involved in the study, the researcher facilitated a workshop for the CWG to share knowledge about the PAR process, methods of qualitative data collection, and updating EBP for CAUTI prevention. The role of the core CWG as a team to be leading their units was then established.
