Competing Interests

The PhD project is co-funded by Amgros I/S, Copenhagen, Denmark. However, it is important to emphasize that Amgros had no role in the execution of the study, such as study design, data collection analysis, decision to publish, or preparation of the manuscript. In Denmark the healthcare system is primarily funded by taxes. Public hospitals purchase medicines through tendering and procurement which is a national task carried out by Amgros. Amgros I/S is a noncommercial company owned by the five Danish Regions. On behalf of the Regions, Amgros secures patients access to new and effective treatments and devices, just as a high level of security of supply is ensured and drug relates costs are restrained. The tendering and procurement of medicine takes place in close collaboration with hospital pharmacies, drug committees, the Danish Medicines Council, suppliers and heads of procurement in the Regions. This task would otherwise be maintained independently by the five regions. Therefore, Amgros plays a central role in ensuring supply of medicine and supporting patient safe drug changes in public hospitals, but has no economic interest in the present study. With this competing interest statement, I, Joo Hanne Poulsen, confirm that the co-funding from Amgros I/S to the PhD project, does not alter our adherence to PLOS ONE policies on sharing data and materials.
