Peer review for biomedical publications: we can improve the system

Area of Science:

• Biomedical Publishing
• Scientific Communication

Background:

• Lack of formal training for peer reviewers compromises scientific quality and introduces bias.
• Exponential increase in manuscript submissions overburdens qualified referees, reaching unsustainable levels.
• Current peer review systems face significant challenges impacting the integrity of biomedical publications.

Purpose of the Study:

• To outline the shortcomings and flaws in the existing scientific peer review system.
• To discuss innovative strategies and emerging options for improving the peer review process.
• To address the risks posed by inadequate peer review to the quality of biomedical literature.

Main Methods:

• Analysis of current peer review practices and their limitations.
• Review of existing journal initiatives to enhance peer review quality.
• Exploration of alternative peer review models and their potential benefits.

Main Results:

• Identified critical flaws in the traditional peer review system, including lack of training and reviewer overload.
• Highlighted journal efforts such as structured guidelines, referee courses, and biostatistician involvement.
• Presented alternative models like post-publication, decoupled, collaborative, and portable peer review.

Conclusions:

• The current peer review system is inadequate to handle the volume and complexity of scientific publications.
• Innovative approaches and formal training are essential to maintain the quality and reliability of biomedical research.
• Emerging peer review strategies offer promising alternatives to address systemic weaknesses.
