Using the Grade Approach to Support the Development of Recommendations for Public Health Interventions in Radiation...

Area of Science:

• Public Health
• Radiation Safety
• Evidence-Based Medicine

Background:

• World Health Organization (WHO) guidelines require transparent development based on synthesized evidence.
• Formal assessment of evidence quality is mandated for WHO guideline development.

Purpose of the Study:

• To develop WHO recommendations on public health interventions for radiation emergencies.
• To ensure transparency and evidence-based quality in guideline development.

Main Methods:

• Applied the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
• Formulated 10 PICO (Population, Intervention, Comparator, Outcomes) questions.
• Conducted extensive evidence searches and systematic reviews.
• Utilized the evidence-to-recommendation (E-2-R) decision-making matrix.

Main Results:

• Developed recommendations for public health interventions during early/intermediate and late phases of radiation emergencies.
• Formulated recommendations for risk communication strategies to mitigate psycho-social impacts.
• Assessed the quality of evidence and strength of recommendations for each PICO question.

Conclusions:

• The GRADE approach was successfully applied to develop WHO recommendations on public health interventions in radiation emergencies.
• The methodology ensures transparency and rigorous assessment of evidence, strengthening the recommendations.
• The recommendations address critical aspects of response and risk communication in radiation emergencies.
