Ethics and Research
• Who has done research? Published?• When do you think are some ethical
issues in research• Have you encountered ethical issues in
research?

A few questions about ethics in research
• Lack of informed consent – Do patients-subjects know what they are consenting to?
• Mistreatment of subjects – Are subjects being treated fairly, not being abused?
• Falsification of data – Is evidence-based medicine reliable?
• Conflicts of interest – Is unfavorable data suppressed?
• Authorship – Do we really know who is responsible for conducting a study?

Prevalence of scientific misconduct: Fanelli2% scientists admit to serious misconduct – fabrication, falsification, plagiarism34% admit to questionable practices – dropping data points, changing research design to get favorable results

Studying Scientific Misconduct
• International Committee of Medical Journal Editors• Emanuel et al. What makes clinical research ethical?• Data falsification and fabrication• Fall 2012 - The Integrity of Evidence-Based Medicine
– History of ethics in medical research• Tuskegee
– Institutional Review Boards– Medical industry, medical research, and medical
education

ICMJE
• International Committee of Medical Journal Editors– JAMA, NEJM, Lancet, BMJ, many others– http://www.icmje.org/– Authorship, contributorship, and editorship– Peer review– Conflicts of interest– Privacy and confidentiality– Protection of human subjects and animals in research– Obligation to publish negative findings– Overlapping publications
![Page 8: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/8.jpg)
ICMJE - Authorship
• Author means having made substantial intellectual contribution
• Design, data acquisition, and/or analysis• Draft or revision of article, final approval • Each author should be able to take public
responsibility for the work
![Page 9: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/9.jpg)
Ghost authors and “Guest” authors
• Wislar et al. – 896 Corresponding authors published in JAMA, NEJM, Lancet,
PLoS Medicine, Ann Int Med, Nature Medicine• Ghost authorship 11.0% in original research articles• Honorary authorship 25% in original research articles• 21% articles with inappropriate authorship
• Gotzsche et al. PLoS Medicine– http://www.plosmedicine.org/article/info:doi/10.1371/
journal.pmed.0040019 – 75% industry sponsored trial with ghost authors (stats mostly)
• Major textbook of psychiatry ghost authored• Use of Prempro, HRT based on ghost authored paper• Vioxx studies by Merck used honorary and ghost authors

ICMJE – Peer review
• Peer review process not specified by ICMJE• Purpose: to provide fair, disinterested input on
quality of article submitted– Blinded review (identity of author(s) removed)– Random selection of qualified reviewers– Reviewers disclose conflicts of interest– Having a peer read a paper is not peer review– Reviewers paper’s contents
![Page 11: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/11.jpg)
Concerns with peer review
• Not truly blinded• Misuse of information learned during peer
review• Peer review may be biased against
revolutionary ideas
![Page 12: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/12.jpg)
ICMJE – Conflicts of interest
• Freedom from financial or personal interests that create bias– Disclosure vs meaningful disclosure of
financial interests– Other interests: personal relationships,
academic competition, bias about value of work
• Editorial Conflicts of interest– Revenue from advertisers
![Page 13: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/13.jpg)
ICMJE – Privacy and confidentiality
• Protect identity of subjects, patients– Remove identifying information or disguise
• Patient in her 40s vs 46 year old– Informed consent if potentially identifiable
• Author and reviewer confidentiality should be protected
![Page 14: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/14.jpg)
ICMJE – Protection of human subjects
• Paper should state whether study was carried out according to Helsinki Declaration
• IRB approval • Protection of animal subjects
![Page 15: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/15.jpg)
ICMJE – Negative studies
• Publication bias – failure to publish negative trials– Undermines meta-analytic studies of efficacy
• Antidepressants• Many journals require studies to have
been registered with clinicaltrials.gov
![Page 16: Ethics and Medical Research](https://reader035.vdocuments.us/reader035/viewer/2022062410/568163f8550346895dd59083/html5/thumbnails/16.jpg)
ICMJE – Duplicate submissions
• Submit to one journal only• If there are conflicting or competing
publications from the same study, the journal editor should be informed
