Large Language Model-based Chatbot as a Source of Advice on First Aid in Heart Attack

The ability of the cutting-edge large language model-powered chatbots to generate human-like answers to user questions hypothetically could be utilized for providing real-time advice on first aid for witnesses of cardiovascular emergencies. This study aimed to evaluate quality of the chatbot responses to inquiries on help in heart attack. The study simulated interrogation of the new Bing chatbot (Microsoft Corporation, USA) with the "heart attack what to do" prompt coming from 3 countries, the Gambia, India and the USA. The chatbot responses (20 per country) were evaluated for congruence with the International First Aid, Resuscitation, and Education Guidelines 2020 using a checklist. For all user inquiries, the chatbot provided answers containing some guidance on first aid. However, the responses commonly left out some potentially life-saving instructions, for instance to encourage the person to stop physical activity, to take antianginal medication, or to start cardiopulmonary resuscitation for unresponsive abnormally breathing person. Mean percentage of the responses having full congruence with the checklist criteria varied from 7.3 for India to 16.8 for the USA. A quarter of responses for the Gambia and the USA, and 45.0% for India contained superfluous guidelines-inconsistent directives. The chatbot advice on help in heart attack has omissions, inaccuracies and misleading instructions, and therefore the chatbot cannot be recommended as a credible source of information on first aid. Active research and organizational efforts are needed to mitigate the risk of uncontrolled misinformation and establish measures for guaranteeing trustworthiness of the chatbot-mediated counseling.
