Clinical Study Reports (CSRs): A Medical Writer's Guide On How To Write Them

Do you feel overwhelmed when faced with the task of writing a clinical study report (CSR)?

Then you’re not alone. 

Navigating this complex and often confusing process can be challenging, especially for novice medical writers. But fear not; I’m here to help you with this Akasious blog.

In this blog, I’ll share my top tips and best practices for writing CSRs that are clear, concise, and accurate. 

Let’s begin to understand how you can easily navigate this complex process.

What is a Clinical Study Report, and Who Writes it?

A Clinical Study Report (CSR) is a comprehensive document that summarizes the results and analyses of a clinical trial. It includes details about the study’s design, conduct, results, and conclusions drawn from the data.

The CSR serves as the primary document for the study’s sponsor to fulfill regulatory requirements for a drug or device marketing approval. Medical writers who are part of the drug or device development team write the CSR. These medical writers collaborate with clinical trial experts, statisticians, and other stakeholders to collect and analyze data from the clinical trial.

After that, they write a comprehensive report that accurately and explicitly summarizes the study’s results. The medical writer also ensures that the CSR meets regulatory requirements and follows a standard format.

What are the Four Types of Clinical Study Reports?

Four types of Clinical Study Reports (CSRs) are commonly written in drug and device development. And these are:

  1. Full CSRs: These comprehensive reports provide a detailed overview of the clinical trial process, from the study design to the final results and conclusions.

  2. Abbreviated CSRs: These shorter reports summarize the most critical findings from the clinical trial. They can be used in cases where an entire CSR is unnecessary or when a sponsor needs to communicate study results to regulatory authorities quickly.

  3. Integrated Summaries of Safety and Efficacy (ISS/ISE): These reports integrate data from multiple studies, usually for regulatory submission. The ISS/ISE comprehensively summarizes a drug’s or device’s safety and efficacy data across different studies.

  4. Periodic Safety Update Reports (PSURs): These reports provide an update on the safety of a drug or device over a defined period. They are typically written regularly and submitted to regulatory authorities as part of ongoing pharmacovigilance activities.

What is the Clinical Study Report (CSR) Outline?

The outline of a Clinical Study Report (CSR) follows a standard format recommended by regulatory authorities, such as the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH). 

The standard format consists of the following sections:

Title page

The title page is the first page of the CSR and includes essential information such as the report’s title, the study sponsor’s name, the study name or number, and the date. Ensuring this page is formatted correctly and contains all the necessary information is crucial.

Table of contents

The table of contents lists the report’s main sections, subsections, and page numbers. It provides an overview of the report’s organization and helps readers easily navigate its sections.

Introduction

The introduction provides an overview of the study, including its background, objectives, and hypothesis. It sets the stage for the rest of the report and helps readers understand the context of the study.

Methods

This section describes the study’s design, patient population, procedures, and statistical analysis methods. It provides a detailed description of how the study was conducted and assists readers in evaluating the quality and reliability of the study’s results.

Results

The results section presents the study’s results, including efficacy and safety data, adverse events, and other relevant findings. For a successful CSR, explain the data clearly and concisely. Use proper tables and figures to help readers understand the results.

Discussion

The discussion section provides an interpretation of the study results, their implications for clinical practice, and any limitations or strengths of the study. It is vital to give a balanced understanding of the results and avoid overgeneralizing or overstating the findings.

Conclusions

This part summarizes the study’s main findings and implications for future research. A medical writer must provide clear and concise conclusions supported by the study results.

References

The references section includes a list of sources cited in the report. Following the preferred citation style and correctly citing all sources is essential.

Appendices

The appendices section includes any additional information relevant to the study, such as study protocols, informed consent forms, and case report forms. Labeling and organizing the appendices is vital so readers can easily find the necessary information.
