Revolutionizing SDTM Programming in Pharma with ChatGPT

By Sarath

Introduction

In the pharmaceutical industry, standardizing clinical trial data through Study Data Tabulation Model (SDTM) programming is a critical task. The introduction of AI tools like ChatGPT has opened new opportunities for automating and enhancing the efficiency of SDTM programming. In this article, we will explore how ChatGPT can assist programmers in various SDTM-related tasks, from mapping datasets to performing quality checks, ultimately improving productivity and accuracy.

What is SDTM?

SDTM is a model created by the Clinical Data Interchange Standards Consortium (CDISC) to standardize the structure and format of clinical trial data. This model helps in organizing data for submission to regulatory bodies such as the FDA. SDTM programming involves mapping clinical trial datasets to SDTM-compliant formats, ensuring data quality, and validating that the data follows CDISC guidelines.

How ChatGPT Can Enhance SDTM Programming

ChatGPT can be a game-changer in SDTM programming, providing real-time support, automation, and solutions for common challenges. Here’s how it can be applied in various stages of the SDTM process:

• Assisting with Mapping Complex Datasets: ChatGPT can provide real-time guidance and suggestions for mapping non-standard datasets to SDTM domains, helping programmers to ensure compliance with CDISC guidelines.
• Generating Efficient SAS Code: ChatGPT can generate optimized SAS code for common SDTM tasks, such as transforming raw datasets, handling missing data, or applying complex business rules to ensure the data meets the regulatory standards.
• Debugging SAS Code: ChatGPT can assist in identifying bugs, suggesting ways to debug code, and improving code readability with useful tips like employing the PUTLOG statement.
• Automating Quality Control Checks: Performing quality checks on large datasets is essential in SDTM programming. ChatGPT can automate parts of this process by generating code for missing variable checks, duplicate observations removal, and ensuring that domain-specific rules are followed.
• Improving Code Readability: By suggesting best practices for writing clear and maintainable SAS code, ChatGPT can help reduce technical debt and make the code easier to review and debug, especially in collaborative settings.
• Providing Learning Support for New Programmers: For beginners in SDTM programming, ChatGPT can explain complex concepts in simple terms, provide examples, and offer real-time solutions to questions related to SDTM domains, controlled terminology, and regulatory requirements.

Practical Use Cases for ChatGPT in SDTM Programming

Let's look at a few examples where ChatGPT can offer tangible benefits in SDTM programming:

• Handling the Demographics Domain (DM): ChatGPT can guide programmers through mapping raw datasets to the SDTM DM domain, offering suggestions for handling specific data types like SUBJID, AGE, and SEX. It can also generate SAS code that adheres to CDISC standards and offers tips for validating the resulting data.
• Generating Define.XML Files: Defining metadata is critical for regulatory submission. ChatGPT can assist by generating SAS code for creating and validating Define.XML files using tools like Pinnacle 21, ensuring compliance with regulatory expectations.
• Managing Controlled Terminology: Keeping up with the latest controlled terminology versions (e.g., MedDRA, SNOMED, UNII) is essential. ChatGPT can suggest updates for domain-specific controlled terminology and provide SAS code to automate its application in SDTM datasets.

Limitations and Future Potential

While ChatGPT offers significant advantages, there are still some limitations. For instance, it lacks deep integration with SAS or Pinnacle 21, which means that users need to manually adapt ChatGPT’s suggestions to their specific environments. However, the future potential for ChatGPT to evolve into an even more intelligent assistant is immense. As AI technology advances, ChatGPT could become an essential tool for real-time error detection, domain mapping, and automating SDTM processes end-to-end.

Conclusion

ChatGPT has the potential to transform the way SDTM programming is done in the pharmaceutical industry. From guiding new programmers to automating repetitive tasks and assisting with complex coding challenges, this AI tool can significantly improve the efficiency and accuracy of SDTM workflows. As we continue to explore the capabilities of AI, the integration of tools like ChatGPT into programming environments will become an increasingly vital asset for organizations looking to streamline their clinical data management and regulatory submission processes.
