What Defines Good Quality in a Clinical Study Report?

Area of Science:

• Clinical Research
• Medical Writing
• Regulatory Science

Background:

• Clinical study reports (CSRs) are central to drug development but their quality attributes are under-researched.
• Existing guidelines (e.g., ICH E3) offer limited detail on CSR quality features.
• Medical writing literature often overlooks the critical elements defining CSR quality.

Purpose of the Study:

• To identify and define the key elements contributing to the overall quality of clinical study reports.
• To understand the multifactorial nature of CSR quality from the perspective of experienced medical writers.

Main Methods:

• Guided interactive introspection was employed with a group of 28 medical writers.
• Participants possessed science backgrounds (PhD) and varied professional experience (1-17 years).
• 16 distinct quality items were identified and categorized into 5 major areas.

Main Results:

• Five major quality areas identified: language, document structure, numerical information, audience focus, and company context.
• The top 10 quality elements, ranked by importance, include correctness, completeness, regulatory compliance, clarity, conciseness, consistency, timeliness, appropriate language, adequate conclusion, and project alignment.
• CSR quality is multidimensional, not reducible to a single attribute.

Conclusions:

• Optimal clinical study report quality is achieved through a balanced application of professional judgment across multiple identified quality elements.
• Medical writers must consider a comprehensive set of factors beyond basic compliance to ensure high-quality CSRs.
• Future efforts should focus on integrating these quality dimensions into medical writing practices and training.
