"The Regional Committee on Health Research Ethics in Central Denmark Region reviewed the study protocol and claimed that permission was not required since it did not comply as a biomedical study. The study was registered at the Danish Health and Medicines Authorities and permission was granted to seek information in the included patients’ medical records. The permission also included patients who were unable to give written consent due to acute illness or cognitive state since these vulnerable patients were considered to benefit from the intervention. Written informed content was obtained from patients who were not cognitively impaired or too ill to be informed. The study was approved by the Danish Data Protection Agency and registered in ClinicalTrials.gov (identifier: NCT01819974)."
