Misconduct in Biomedical Research: A Meta-Analysis and Systematic Review

Area of Science:

• Biomedical research ethics
• Scientific integrity
• Publication ethics

Background:

• Research misconduct poses a significant threat to the integrity of scientific findings.
• Understanding the prevalence of misconduct is crucial for implementing effective preventive measures.
• Previous studies have varied in their methodologies and reported rates of misconduct.

Purpose of the Study:

• To assess the nature and prevalence of scientific misconduct in biomedical research.
• To compare misconduct rates between self-reported and nonself-reported studies.
• To provide a pooled estimate of research misconduct globally.

Main Methods:

• A comprehensive literature review was conducted using PubMed Central, PubMed, and Google Scholar.
• MeSH terms and keywords related to scientific misconduct were used in Boolean searches.
• 16 selected articles underwent meta-analysis using Open Meta Analyst software.

Main Results:

• Plagiarism, data fabrication, and falsification were common findings across reviewed articles.
• Prevalence rates for plagiarism were 4.2% (self-reported) and 27.9% (nonself-reported).
• Data fabrication rates were 4.5% (self-reported) and 21.7% (nonself-reported); falsification rates were 9.7% (self-reported) and 33.4% (nonself-reported).

Conclusions:

• Biomedical research exhibits an alarming rate of misconduct, particularly in nonself-reported studies.
• Nonself-reported studies demonstrated substantially higher prevalence of misconduct than self-reported studies.
• The findings underscore the urgent need for enhanced oversight and ethical standards in biomedical publication.
