Here is the inside story on how @UpToDate does what it does. From my experience as an author/section editor for UpToDate for 20 years, here is how it works. It’s amazing! Every day a team of people @UpToDate scour the top medical journals (and major meeting abstracts) for articles of importance. In my case they pertain to myeloma and related disorders. Any article that is felt to be important is sent to a expert MD medical editor at UpToDate who reviews the paper. If the information is felt to be important, the relevant chapter is updated with this content, summarized in a few sentences in Word track and then sent to the author of the chapter who is a top expert in the field. As an author I have to review the update in detail and then make a decision whether to include the new information, and whether the way it has been incorporated is correct or needs to be edited. Once I make a decision, it is then reviewed by an expert section editor. For 15 years for me, the section editor was Dr. Robert Kyle! (Currently I’m the section editor and we have about 6 experts serve as authors on over 40 chapters pertaining to myeloma and related disorders). The section editor independently decides whether the author made the right call and either approves or we have a back and forth till we agree. The updated chapter is then reviewed again by the expert MD editor at UpToDate and then posted. For important phase III trials or FDA approvals we usually make the update within a week. Sometimes by the next day! With so many important papers, every week there are 2-3 updates pertaining to my chapters that go through the above process! It’s hard work but it keeps me ridiculously current. And more importantly it keeps the content accurate and current. This is not random addition of new information. It’s vetted information that’s added. Every UpToDate chapter is also peer reviewed annually. Each chapter also undergoes an annual author and editor review to make sure that the overall content and flow is good and to delete content that may be no longer important or accurate. The extraordinary process and rigor involved is why it’s such an invaluable irreplaceable resource. It is AMAZING and hard to replicate. UpToDate is easy to navigate. But the newly launched UpToDate Expert AI takes it to the next level! It makes the entire content available to query just like you query a top ranked LLM. But it’s not searching the random internet or a stack of published articles. It’s primarily trained and derives vetted and adjudicated UpToDate content. It will not randomly hallucinate. It will not list 10 options for treatment newly diagnosed myeloma but will give you what experts currently feel is the best option based on the latest evidence. All answers are referenced and pointing to specific content sections in UpToDate (which also has links to source material). So you can immediately get all the background information if you need more detail. Working with UpToDate has helped my career immensely. For the last 20 years it has been impossible for me to not know about every important study related to myeloma and related disorders as they get published! For 20 years, I have received a precise summary of every important article published in my field. More importantly I am forced to read them, review the source material, and make a judgment call. As a result I remember this stuff. A gift indeed!
