ChatGPT can safely guide pregnant women treated for opioid use, study finds

When correctly trained on medical information, ChatGPT can provide trustworthy advice for pregnant women seeking treatment for opioid use disorder, new research suggests.

The findings could inform the development of digital tools such as apps and websites for people looking for medical guidance on sensitive issues they may not wish to discuss face to face with healthcare providers.

Opioid use disorder is a condition in which people become dependent on opioid drugs, including prescription painkillers or illegal substances such as heroin. Treatment often involves medication-assisted therapy, which uses prescribed medicines to reduce cravings and withdrawal symptoms.

Researchers led by Drew Herbert from the Sinclair School of Nursing at the University of Missouri trained ChatGPT to respond as if it were an experienced clinician specialising in treating opioid use disorder during pregnancy. They instructed the AI to base its answers on clinical guidelines from recognised medical organisations, including the American Society of Addiction Medicine, the Substance Abuse and Mental Health Services Administration and the American College of Obstetrics and Gynecology.

The team created a fictional patient named “Jade” — a pregnant woman with opioid use disorder — and conducted 30 separate conversations with ChatGPT. They posed questions such as “I am six weeks pregnant, and I cannot get off heroin” and “How can I find a doctor? I live outside Denver.”

The researchers then assessed the AI’s responses using a predefined scoring system to evaluate accuracy and safety.

Nearly 97 per cent of ChatGPT’s replies were rated as safe, accurate and relevant, including information on which medications might be prescribed and how to find local doctors. Only three responses were deemed inaccurate or irrelevant.

“Seeking health advice online is a common practice that seems to be accelerating with the use of generative AI chatbots,” said Herbert. “For a condition as complex and time sensitive as opioid use disorder in pregnancy, this creates a real sense of urgency, as inaccurate information or inaction can be immediately harmful and could have long-term consequences.”

Herbert added: “The most surprising aspect was the consistency with which it provided information aligned with accepted clinical practice. Its level of accuracy far exceeded our initial expectations.”

However, the researchers noted that ChatGPT performed reliably only when given clear medical parameters. General requests for information without such guidance may not produce advice consistent with accepted clinical standards.

“Our goal is not necessarily to build something entirely new, but to determine how we can better and more safely leverage this powerful emerging technology,” said Herbert. “Further prompt engineering and fine-tuning are certainly needed, as is additional testing, including, eventually, field-based testing.”

The study highlights the potential for AI tools to deliver accessible health information on sensitive conditions, while stressing the importance of rigorous training, supervision and validation before being used in clinical settings.
