How Does Med-PaLM Compare to Competitors?

vs GPT-4

Med-PaLM 2 is better than GPT-4 at many of the established medical benchmarks (Med QA = 86.5% vs 81.4%) and is less likely to cause adverse effects and does not exhibit demographic bias.

Use Med-PaLM 2 when you need medical precision and use GPT-4 for general healthcare AI applications.

vs MedGemma

Although both are developed from Google Health, Med-Gemma uses multimodal (radiology and dermatology) while Med-LM is used to train clinical reasoning.

Use Med-LM when you want to perform clinical workflows based on text and Med-Gemma when you want to analyze medical images.

vs Claude/Anthropic

Claude is stronger in the area of safety and alignment but is not trained using the same type of data as Med PaLM 2 was. Med-PaLM 2 was built for the purpose of being a medical model, and it has been evaluated by physicians for its accuracy and reliability across 9 different clinical areas.

Use Med-PaLM 2 if you need to deploy the program in a regulated healthcare environment, and use Claude for general purposes that require you to be safe conscious.

vs Llama 3.1 Healthcare variants

Although the open-source versions of these programs would be less expensive to implement than Med-PaLM 2, there is no equivalent level of evidence that supports their use for the deployment of validated medical information, nor is there an equal amount of support for deploying them into an enterprise healthcare environment.

Use Med-LM when you need to deploy the program into a production healthcare environment, and use Llama when you need to experiment or test your ideas.

What Are Common Questions About Med-PaLM?

Med-PaLM 2 is a large language model that was fine-tuned by Google for healthcare. This large language model was fine-tuned specifically to provide physicians and other health care providers with diagnostic suggestions, treatment recommendations and patient outcome predictions while assisting them with their decision-making processes and avoiding the need to replace the provider's own professional judgment

Med-PaLM 2 achieves 85.4% accuracy on USMLE-style questions, similar to what an expert test-taker would score, and 72.3% on Indian AIIMS/NEET style medical exams. The original Med-PaLM achieved 67.6% accuracy and represents a 18% increase over the original Med-PaLM model

A primary function of MedLM will be to assist in clinical decision support and provide for the creation of an electronic medical record of doctor-patient interactions that will be generated automatically by MedLM.

The initial adopters of MedLM include HCA Healthcare which is testing the model with 75 physicians in four emergency rooms, Mayo Clinic, Meditech (the EHR vendor), Augmedix, Accenture, and Deloitte.

Currently, MedLM is only accessible by Google Cloud users who have a presence in either the healthcare or life sciences industry.

MedLM is a family of foundational models based upon Med-PaLM 2, and were released in December of 2023. The models include both large and medium-sized models that are designed to fit the requirements of the specific use case and are available via Google Cloud's Vertex AI platform; the availability of these models is wider than the original Med-PaLM 2.

HCA Healthcare's use of MedLM in its clinical setting utilizes HIPAA compliant platforms (Augmedix), and therefore the processing of the medical records and doctor/patient conversations will occur within a secure environment and in accordance with all applicable laws and regulations related to the healthcare industry.

Several key limitations exist for MedLM, including the possibility of error occurring when a high degree of accuracy has been achieved, there are no regulatory guidelines governing the use of artificial intelligence in healthcare, there may be complexities involved in addressing the nuances of medical questions asked by patients and clinicians, and MedLM is not intended to act as a replacement to physician-based decision making, but rather as a tool to aid in such decisions.

Access to MedLM is available through Google Cloud's Vertex AI platform and is available to allow listed Google Cloud customers in the healthcare and life sciences industries. Customers in the healthcare and life sciences industries should contact their Google Cloud account teams to obtain access to MedLM.

The Med-PaLM 2 model was specifically fine-tuned using large amounts of medical data and achieves expert level results on medical exams. In contrast, general language models do not possess the same degree of domain specialization and medical knowledge base as Med-PaLM 2, and as such are less reliable for clinical use cases. HCA Healthcare successfully tested automated medical note generation in emergency department settings to free up physician time. Mayo Clinic and several other healthcare systems are testing MedLM in a variety of clinical applications, with plans to expand usage as the technology continues to improve.

Is Med-PaLM Worth It?

Med-PaLM 2 demonstrates how AI can be applied in a meaningful way to help address some of the most pressing challenges in the healthcare industry; Med-PaLM 2 has achieved an expert level of performance in medical exams, and has demonstrated real-world value in clinical documentation and decision support. Med-PaLM 2 is specifically designed to meet the unique challenges that are inherent in the healthcare industry, and it leverages the vast amount of research-based experience of Google in this area. However, at present, Med-PaLM 2 is still in the early access preview mode with limited availability; there are still many unanswered questions regarding how errors will be handled in high-stakes settings; and the overall regulatory framework surrounding AI in the broader healthcare market is still undefined.
