The NHS REC flowchart can be found: ExternalRef removedWe felt that this vital information should be shared with the wider medical community and so a manuscript was prepared and submitted to BMC. Consent was not sought at the time of patient admission as they were not being enrolled into any study. All patient healthcare data were collected anonymously, retrospectively and no patient identifiable data were collected or described in the manuscript. This was in line with the NHS Health Research Authority guidance [CitationRef removed].
