One size does not fit all: Guidelines for designing a score sheet for animal experiments - eight essential steps

Area of Science:

• Animal research ethics
• Laboratory animal science
• Regulatory compliance in research

Background:

• EU Directive 2010/63 and Swiss Animal Welfare Legislation mandate monitoring animal experiments.
• Assessing animal welfare and procedure severity is crucial for ethical research.
• Existing score sheets often have flaws or are not universally applicable.

Purpose of the Study:

• To propose a standardized yet adaptable eight-step procedure for designing animal experiment score sheets.
• To provide a framework for creating effective tools that adhere to the 3Rs principle (Replacement, Reduction, Refinement).
• To ensure score sheets are suitable for any animal species and experimental context.

Main Methods:

• Development of an eight-step procedural guide for score sheet design.
• Emphasis on adapting score sheets to specific experimental needs and animal species.
• Focus on integrating welfare monitoring and severity assessment into the score sheet.

Main Results:

• A flexible, eight-step methodology for creating customized animal experiment score sheets.
• The proposed method addresses limitations of existing score sheets, enhancing their utility.
• The procedure facilitates compliance with animal welfare regulations and the 3Rs principle.

Conclusions:

• The presented eight-step procedure offers a robust method for developing effective animal experiment score sheets.
• This approach supports ethical animal use in scientific research by improving welfare monitoring and severity assessment.
• The adaptable design ensures broad applicability across diverse research settings and species.
