ChatGPT has lots of potential for use in public health, but how well does it actually perform? Public Health On Call intern Caroline Wang and Lindsay Smith Rogers discuss three potential uses—seeking personal medical advice, public health research for students, and as a practical resource for practitioners. They go over some specific prompts and analyze what the chatbot does well and where it’s limited. Caroline is a Masters of Health Science student at the Johns Hopkins Bloomberg School of Public Health studying clinical epidemiology and has been an intern for the podcast since March 2020.
