Kudos for the Informatics Professor - 2023 Update
Informatics Professor

1M ago
Periodically in this blog, lately once a year, I review all of my professional accomplishments, including honors, talks given, papers published, and more for the past year. Last year was a transitional year for me professionally, as I stepped down from two leadership positions as Chair of the Oregon Health & Science University (OHSU) Department of Medical Informatics & Clinical Epidemiology (DMICE) and from being Director of the OHSU Biomedical Informatics Graduate Program. As seen in this post, however, my productivity did not miss a beat in 2023, and in fact I am enjoying my work as ..read more

Translational AI: A Necessity and Opportunity for Biomedical Informatics and Data Science
Informatics Professor
by William Hersh, MD
1M ago
How much of the hype for artificial intelligence (AI) that will truly impact health, healthcare, and research is an unknown. The potential benefits are unequivocal, from assistant patients pursue actions to improve their health to giving guidance to clinicians in diagnosis and treatment to helping researchers find information and devise new ideas to advance their research. I have published an invited post in the National Library of Medicine (NLM) Musings from the Mezzanine Blog, the blog of the Director of the NLM. I chose to update some of my past writings posted in this blog with a new ..read more

Whither Search? A New Perspective on the Impact of Generative AI on Information Retrieval (IR)
Informatics Professor
by William Hersh, MD
2M ago
When I was putting the finishing touches on the 4th edition of my textbook on information retrieval (IR, also known as search) in the domain on biomedicine and health in 2020, I wondered whether the major problems in the field of IR were mostly solved. Retrieval systems such as Google for general Web searching and PubMed for the biomedical literature were robust and mature. One literally had the world’s written knowledge at their fingertips for general and biomedical topics from these systems respectively (even if paywalls did not always allow immediate access to the content). There were certa ..read more

Annual Reflections at the End of 2023
Informatics Professor
by William Hersh, MD
3M ago
Keeping with my tradition for this blog, I am ending this calendar year with my retrospective on the past year and some musings looking forward. The number of postings I make to this blog continues to decline each year. It is not that I do not have a lot to say, but rather I do not seem to have as much time to say it. One thought has been to move to a different medium, such as a podcast. While I do listen to a fair number of podcasts, I still myself seem to prefer my words to be written. If nothing else, text seems more accessible. Another option would be to switch to something like a Substack ..read more

More Evidence That We Need More Evidence for AI Interventions
Informatics Professor
by William Hersh, MD
7M ago
In my previous post, I related the case of an excellent model that predicted hospital readmission yet when used in the context of real-world effort to reduce admissions was not able to lower the rate. Some new studies highlight this scenario again of excellent models and systems that, when studied, do not show real-world benefit. A couple papers in Annals of Internal Medicine find a similar scenario for one of the earliest uses of artificial intelligence (AI) to demonstrate success, which is computer-aided detection (CADe) of polyps during colonoscopy results. A systematic review of previous c ..read more

Lessons About Clinical AI From a Randomized Controlled Trial of Hospital Readmissions
Informatics Professor
by William Hersh, MD
9M ago
Our news ands science feeds are so filled these days with everything artificial intelligence (AI), from large language models to their impacts on society, that we may miss important studies on other informatics topics, some of which may have lessons for AI. This is the case for a recent randomized controlled trial (RCT) on a hospital readmissions initiative (Donzé, 2023) and an accompanying editorial putting it in larger perspective.(Wachter, 2023) Some may remember about a decade ago, when “data analytics” was the rage, and health insurance payors were noting with alarm the growing rate of ho ..read more

Please Share Your Slides When You Start Your Talk
Informatics Professor
by William Hersh, MD
10M ago
I know that some people lament death by Powerpoint, but I find a speaker's slides generally valuable as both a listener and a speaker. Yes, many people (including me!) could do better with slides, but I find them useful. As a speaker, they help me keep track of everything I want to say, and drive home some points with visuals or reference lists. As a listener, I can keep track of what is being talked about, pursue any references I might be interested in further, and view graphics that often bring home points that words (especially spoken-only)  do not. My general practice when giving ..read more

Reports of My Retirement Are Greatly Exaggerated
Informatics Professor
by William Hersh, MD
10M ago
As most of my world knows, I stepped down as Chair of the Department of Medical Informatics & Clinical Epidemiology (DMICE) at Oregon Health & Science University (OHSU) at the end of last year. In addition to announcements made by OHSU, I let my world know with postings in this blog, on social media, and via some email lists. I was gratified by the many nice accolades that I received but one thing was unsettling. This was those who wrote to congratulate me on my retirement. It was unsettling because I wanted to make explicit that I was not retiring, and instead was passing on the ..read more

It's All Informatics to Me: Data Analytics, Data Science, Digital Health, AI, and Whatever is Next
Informatics Professor
by William Hersh, MD
11M ago
In the last decade or so, a number of new names have emerged for the kinds of activities historically studied, disseminated, and taught by those who work in biomedical and health informatics. Each of these areas has emerged as a "hot topic" in biomedicine and healthcare, with resulting academic funding opportunities, new courses or degree programs, and even academic centers or institutes bearing their names. I suppose I have some skin in this game because I have spent my life's work among those developing the field that I consider to go by the over-arching term of this all, biomedical and heal ..read more

Learning Data Science and Machine Learning with Orange
Informatics Professor
by William Hersh, MD
1y ago
I have written over the years that understanding data science (DS), machine learning (ML), artificial intelligence (AI), and related topics is essential for anyone who works in a profession where tools using them might be employed. This is certainly the case in biomedicine, both in clinical practice and research. In the same sense that all physicians should have basic knowledge of pharmacology, radiology, and other topics, even if they are not experts in the science and methods of those diverse disciplines, all in healthcare should be ready for ML and AI tools coming to their work. Of course ..read more
