# Using AI to improve patient access to clinical trials Source: [https://openai.com/index/paradigm/](https://openai.com/index/paradigm/) Looking forward, Paradigm is excited about how they can leverage GPT‑4’s natural language understanding to further reduce the burden for clinicians\. Rather than needing to write code to analyze data, clinical teams could have a dialog with ChatGPT about a patient’s data, to understand their eligibility for trials, missing information, and next steps\. Paradigm is excited about how they can continue to increase the patient screening rate\. With GPT‑4, their platform can potentially evaluate**hundreds of patients per minute**\. Compare this to a typical nurse research coordinator, who can manually review around 50 patients*per day*\. These efficiency gains can lead to a world where patients have far better access to clinical trials, physicians and nurses can spend more time on patient care and less time on documentation, and new life\-saving therapies are brought to market sooner\.
