We should begin the curriculum with the previously mentioned applications, perceived by internal residents as most useful. Additional applications can be appended in the future. Finally it is necessary to expand the number of experts to supervise the residents.BACKGROUND Harmonization in hand hygiene training for infection prevention and control (IPC) professionals is lacking. We describe a standardized approach to training, using a "Train-the-Trainers" (TTT) concept for IPC professionals and assess its impact on hand hygiene knowledge in six countries. METHODS We developed a three-day simulation-based TTT course based on the World Health Organization (WHO) Multimodal Hand Hygiene Improvement Strategy. To evaluate its impact, we have performed a pre-and post-course knowledge questionnaire. The Wilcoxon signed-rank test was used to compare the results before and after training. RESULTS Between June 2016 and January 2018 we conducted seven TTT courses in six countries Iran, Malaysia, Mexico, South Africa, Spain and Thailand. A total of 305 IPC professionals completed the programme. Participants included nurses (n = 196; 64.2%), physicians (n = 53; 17.3%) and other health professionals (n = 56; 18.3%). In total, participants from more than 20 countries were trained. Ahand hygiene model proved to be effective in enhancing participant's knowledge, sharing experiences and networking. IPC professionals can use this reference training method worldwide to further disseminate knowledge to other health care workers.BACKGROUND Doctoral supervision is a distinct form of supervision with clearly defined responsibilities. One of these is the delivery of effective face-to-face feedback to allow superv
