OpenAI released ChatGPT about five months ago, and followed it up with GPT4 in March. Tech giants and startups have started exploring the potential for LLMs and generative AI tools in healthcare, medicine, clinical settings, and research.
The healthcare industry is increasingly integrating LLMs due to their ability to enhance patient experiences and automate various management tasks, leading to improved efficiency and productivity. These models can simplify interactions between patients and healthcare organisations, providing medical advice, answering health questions, and automating certain tasks such as collecting clinical data and assessing diagnoses. The use of such chatbots in healthcare is expected to continue to grow due to ongoing investments in artificial intelligence and the benefits they provide.
Here’s a list of LLMs in healthcare.
MedPaLM is a large medical language model created by Google Research and DeepMind to answer medical questions. It was introduced in December 2022 and was benchmarked on MultiMedQA, which evaluates its ability to answer a variety of medical questions. The model includes datasets for multiple-choice questions and longer responses for both medical professionals and non-professionals.
Additionally, a new dataset called HealthSearchQA was added to MultiMedQA. In March 2023, Google announced the latest version of MedPaLM at its annual event called “The Check-Up”. The model achieved an 85% score on USMLE MedQA, comparable to an expert doctor, and surpassed similar AI models such as GPT-4. The team also evaluated the model against 14 criteria, including scientific accuracy, exactness, conformity with medical consensus, logical thinking, partiality, and potential for harm.
Google identified significant disparities and pledged to work with researchers and healthcare professionals to narrow them and improve healthcare services. In addition to MedPaLM, Google launched the PaLM API, allowing developers to construct applications using Google’s large language model.
Doximity, a digital platform for medical professionals, has launched a beta version of a tool called DocsGPT.com that uses ChatGPT to help doctors with administrative tasks such as drafting and faxing pre-authorisation and appeal letters to insurers.
