Hear it from us
Our approach to content integrity
Why does integrity matter so much? Because every clinical decision depends on trustworthy evidence. In this video, we explain how we prevent bias, protect the scholarly record, and act when concerns arise.
From robust policies to transparent corrections and retractions, we show what integrity looks like in practice, and why it underpins better care.
How we handle the most difficult challenges
Some integrity issues are straightforward. Others aren’t. Here, we walk through how we handle tough cases, questionable images, duplicate submissions, undisclosed relationships, and legal concerns.
You’ll see how we assess evidence, consult experts, communicate with authors, and document decisions, always aligning with COPE guidance and our policies.
BMJ ethics committee
Launched in 2000, BMJ’s Ethics Committee provides expert advice on ethical issues in editorial decision making. Its members bring deep expertise spanning medicine, research, law, bioethics, journalism, and medical editing, ensuring a broad perspective on the toughest ethical questions.
The committee assists the BMJ Group content integrity team with reviewing and developing editorial policies on the most pressing integrity issues and advises editors on complex ethical questions that arise during routine editorial work and research integrity investigations. These include author disputes and consent issues to suspected research misconduct.
Lessons from the Wakefield case
The importance of strong editorial safeguards was underlined by the Andrew Wakefield MMR vaccine case. Initially published in The Lancet in 1998, the paper falsely claimed a link between the MMR vaccine and autism. Years later, The BMJ exposed the research as fraudulent through a landmark investigation by journalist Brian Deer. His reporting revealed serious data misrepresentation and undisclosed conflicts of interest, leading to the paper’s retraction and Wakefield being struck off the medical register.
This case is a powerful reminder of the consequences of weak integrity systems. It helped develop our current ethics and content integrity structures, including the Ethics Committee, to ensure potential misconduct is identified, investigated, and addressed with rigour and transparency.
