Project collaboration policy


Department of Clinical Epidemiology and Biostatistics (CEB), Faculty of Medicine Ramathibodi Hospital, Mahidol University has introduced CEB data warehouse to utilize data to general researchers in and outside the Faculty for maximizing utilization of disease cohorts, facilitating scientific knowledge, and conducting research. The department formulated a policy and processes as a concern of data using must be responsible and must recognize legal, regulatory, and ethical constraints.


This policy covers all proposal applies for project collaborating and all researches retrieving/using data from CEB data warehouse. The policy developed under the concerns of maximizing the use of data while minimizing the risks of violating patient’s privacy with appropriately manage conflicts of interest.

  • All data will be encrypted and used only for the objectives written in the proposal and must not be transferred to other research teams.
  • Reference and funding information must be acknowledged : “Faculty of Medicine Ramathibodi Hospital, Mahidol University and “National Research Council of Thailand (N42A640323)”
