AI Accelerates Patient Screening for Clinical Trials, Study Shows

The rapid advancement of artificial intelligence (AI) is not just transforming industries; it’s also revolutionizing healthcare research. A groundbreaking study published in JAMA showcases how AI can swiftly screen patients for clinical trial enrollment, making the process faster and more efficient. This innovation could potentially accelerate the availability of new treatments for heart failure and other conditions.

Mass General Brigham Researchers Lead the Charge

A team of researchers from Mass General Brigham, led by Samuel (Sandy) Aronson and Alexander Blood, developed a new AI-assisted patient screening tool called RECTIFIER. This tool was tested in the Co-Operative Program for Implementation of Optimal Therapy in Heart Failure (COPILOT-HF) trial. The results indicate that AI can outperform manual processes, suggesting significant financial and time savings.

“We’re thrilled to see AI make such a substantial impact on screening and trial enrollment in a real-world setting,” said Dr. Aronson, executive director of IT and AI Solutions within Mass General Brigham’s Personalized Medicine department. “This technology offers immense potential and we look forward to expanding its use across various clinical trials.”

AI vs. Manual Screening: A Comparative Analysis

In the study, 4,476 patients were randomly selected to undergo either AI or manual screening. RECTIFIER, a generative AI tool, analyzed patients’ electronic health records to check for eligibility criteria. These criteria included symptoms of heart failure, chronic diseases, and medication history.

Following the AI-assisted screening, researchers conducted a brief manual review for any inconsistencies. This additional step ensured that the AI’s accuracy was maintained while enhancing its efficiency. In contrast, the manual group depended entirely on human reviewers to assess patient charts.

The findings revealed that RECTIFIER screened 458 eligible patients within the trial period. In comparison, the manual screening method identified only 284 eligible patients. This stark difference highlights the superior speed of AI in clinical trial processes.

Patient Enrollment Rates Doupled with AI

After identification of eligible patients, patient navigators contacted them to inquire about participation. Notably, the navigators were unaware of which tool had been used for screening to avoid any bias. The AI group’s enrollment rate was almost double that of the manual group, with 35 patients enrolling compared to 19.

The rate of enrollment in the AI-enabled arm was almost double the rate of enrollment in the manual arm. This means that AI could almost halve the time it takes to complete enrollment in a trial.”

These results suggest that incorporating AI into clinical trial processes can significantly speed up enrollment. Shorter wait times for trials can lead to quicker validation of new treatments, benefiting patients in the long run.

Building on Previous Research

This latest study builds on earlier groundwork conducted by Dr. Unlu, Dr. Aronson, Dr. Blood, and their colleagues. Published in NEJM AI in June, their initial findings demonstrated that RECTIFIER was slightly more accurate in identifying eligible patients from existing health records.

The current study further validates RECTIFIER’s robustness and effectiveness in an active clinical setting. These advancements position AI as a valuable asset in streamlining complex healthcare processes.

The researchers see significant potential in scaling up the use of RECTIFIER beyond Mass General Brigham. By customizing the eligibility questions, the tool can be adapted for a wide range of treatments, including those for cancer, diabetes, and other chronic conditions.

“Our next objective is to see this AI tool employed in clinical trials nationwide,” clarified Dr. Blood, a cardiologist at Brigham and Women’s Hospital and associate director of the Accelerator for Clinical Transformation at Mass General Brigham.

Impact on Patient Access to Treatment

The accelerated screening and enrollment process facilitated by AI could mean that patients gain access to proven and effective treatments much sooner. This is particularly important for conditions like heart failure, which require timely interventions.

By reducing the burden on human researchers and increasing the speed and accuracy of patient screening, AI has the potential to transform not only the clinical trials landscape but also clinical care as a whole.

Conclusion and Future Prospects

The study represents a pivotal step towards integrating AI in clinical research, demonstrating its ability to enhance efficiency and accuracy. As methodologies continue to evolve, the integration of AI in healthcare trials could lead to groundbreaking advancements in patient care.

Looking ahead, the team plans to explore further applications of RECTIFIER in various clinical trial settings. Their ultimate goal is to make AI-assisted screening a staple in healthcare research, benefiting both patients and researchers.

“The future of clinical trials is here and it’s powered by AI,” added Dr. Blood, emphasizing the transformative potential of the technology.

As we move towards a more digital and efficient healthcare system, tools like RECTIFIER are set to play a crucial role in ensuring that patients can benefit from cutting-edge treatments more quickly.
