Healthcare’s Knowledge Problem

Healthcare is becoming a real test of how we sustain knowledge. The challenge is no longer just storing information, but keeping it usable, accurate, and current, while also cutting down the time clinicians spend reviewing charts and writing notes. 

One of the clearest near-term benefits of AI is clinical summarization. Instead of digging through scattered notes, lab results, medication lists, imaging, and visit transcripts, clinicians can get a clear, unified picture of the patient. This is where tools from OpenAI and Anthropic are heading. OpenAI is positioning its healthcare offerings around patient-facing summaries and enterprise systems designed to meet privacy and compliance needs. Anthropic is developing similar healthcare-focused tools and infrastructure, especially for clinical and life-science workflows.

But research shows there is a catch. A recent study on AI-assisted report writing for chronic disease care found that the AI produced high-quality drafts with very few edits and no safety problems. Even so, clinicians spent about the same amount of time reviewing these drafts as they did writing reports by hand. The reason is professional responsibility. In medicine, clinicians feel obligated to check everything carefully, even when the AI is usually right. This creates what researchers describe as an accountability paradox: accuracy alone does not reduce workload if full verification is still required.

Because of this, the real challenge is shifting from asking whether AI can write well to asking how systems can support selective verification. The goal is to let clinicians quickly see what matters, what changed, and what evidence supports each statement, without forcing them to recheck everything from scratch.

Another important development is the push toward better medical memory. Patient information is often scattered across systems, making it hard to trust summaries or recommendations. Efforts to unify labs, medications, visit notes, and recordings into a single, traceable context aim to reduce this fragmentation. When data is well connected and clearly sourced, AI can organize and summarize it without guessing.

Open models are also entering the picture. Google’s medical models, including MedGemma and MedASR from Google, are notable because they support an open, developer-friendly ecosystem. This approach appeals to organizations that want strong medical AI capabilities while keeping local control over data and governance.

Taken together, the pattern is becoming clear. AI that simply drafts text is helpful, but AI that drafts and clearly shows where every claim comes from is far more sustainable. The most promising systems ground their outputs in linked evidence, make data sources and versions easy to audit, and reduce repeated work by improving search, organization, and de-duplication. In healthcare, the most sustainable knowledge is the knowledge clinicians do not have to recreate again and again.

Accelerating Knowledge Innovation: Systematic Review of Reviews on ChatGPT

In the beginning was the Word. It was used in the creation of all other things - from thoughts to stories and histories. However, as the amount of information available grew overwhelming, it became challenging to process and make sense of it all. Early academic reformers introduced the idea of reviews and digests to help navigate this sea of information. But it wasn't until the 1970s that systematic reviews gained popularity, starting in the field of medical research.

Reviews play a crucial role in consolidating a vast array of studies and publications, allowing researchers to weave together the threads of evidence and create a cohesive and informative narrative. However, traditional review processes often require substantial time and the collaboration of multiple researchers to reach a consensus. With the rise of generative AI based on large language models, the power of words can be harnessed to streamline the systematic review process, unlocking new possibilities for learning and knowledge acquisition. By leveraging the capabilities of ChatGPT, researchers can potentially accelerate the production of high-quality reviews, facilitating the dissemination of insights and advancements in various fields of study.

The use of ChatGPT in conducting a systematic review of reviews on ChatGPT itself demonstrates the potential for accelerating the production of high-quality reviews in a timely manner. 

While systematic reviews are considered to be the gold standard in knowledge synthesis, they usually require between 6 months and 2 years to complete and often have a narrow focus. While the methodological shortcuts allow rapid reviews (first mentioned in the literature in 1997) to be conducted in less time and with fewer resources, they also increase the likelihood of introducing bias into the review process and missing important information from grey literature (i.e., preprint servers). 

In 2020, full systematic review was completed by a team of 6 in 2 weeks using automation tools. The most time-consuming tasks were data extraction, write-up, abstract screening, full-text screening, and risk of bias. 4 out of the 6 people on the team were experienced systematic reviewers with complementary skills (three experts in two domains required for the review and one information specialist). 

In 2023, ChatGPT and I were able to complete the review of reviews in one week. We screened 7 large resources of papers, including grey literature and reviewed primary studies in Chinese, German, Indonesian, Norwegian, Portuguese, Russian, and Spanish, in addition to English. 

ChatGPT helped me to filter relevant literature in all languages, extract key information, summarize findings, and even assisted with the synthesis of the overall review, enabling a more efficient and comprehensive analysis.

Our paper illustrates that ChatGPT is expanding into different domains and highlights the need to continually refine and expand the training datasets, ensuring that they are diverse and accurate. Another area of improvement involves developing customized integrations, designing specialized prompt instructions and involvement of domain-specific expert trainers, factual correctness evaluation, and investigation of societal impact.  

Word by word, paper by paper, and review by review, ChatGPT is paving the way for a future where knowledge creation is accelerated, insights are amplified, and breakthroughs are within closer reach.

Organizing the World's information

"My guess is (it will be) about 300 years until computers are as good as, say, your local reference library in doing search,"says Google's first employee and director of technology Craig Silverstein. "But we can make slow and steady progress, and maybe one day we'll get there." (Inside the Wide World of Google CBS News, March 28, 2004). According to CEO Eric Schmidt, people care a lot about information and the possibilities of the unfolding revolution in technology are greater than many of them even realize: “Imagine the scale of the kinds of questions you could ask that you could not ask before.”

The figure is a great compilation of key Google Facts by PingDom. Among the key technical facts not shown here are far-reaching inventions such as Programmable Search Engine (PSE, see patent application) based on the BigTable database (See Research Publication about it in PDF format) and other systems that could help it become more semantic.

The distributed storage system for managing structured data called Bigtable resembles a database sharing implementation strategies with parallel and main-memory databases. Instead of a full relational data model it uses a simple data model with data indexed using row and column names that can be arbitrary strings. A Bigtable is a sparse, distributed, persistent multidimensional sorted map. The map is indexed by a row key, column key, and a timestamp; each value in the map is an uninterpreted array of bytes, although clients often serialize various forms of structured and semi-structured data into these strings, controlling it through careful choices in their schemas.

PSE and other integration technologies may be providing a higher level of semantic analysis.
These techniques could figure out the meaning of content and “fill in the blanks” when an item of information is ambiguous or missing. The idea is to enrich an information object with additional tags so that queries about lineage (where something came from) and likelihood of accuracy (the “correctness” of an information element) can be used to generate a result.

Another new concept is a probabilistic mediated schema automatically created from the data sources. Semantic mappings between the schemas of the data sources are mediated by schemas with probabilities attached to each - to model uncertainty at its core. A deterministic mediated schema created from the probabilistic ones will be exposed to the user who could use the terminology of this mediated schema to interact with the system.

The Semantic Web is emerging to help us get the most out of the world's information. Many interesting applications are already here. Some of them already acquired by major search players - Bing, for example, is based on semantic technology from Powerset that Microsoft purchased in 2008. This blog article is only about one of the players organizing the world's information. Stay tuned for more.

Building dynamic Web 3.0 databases

This world is too complex to be described by rigid tables. The 40-year old relational technology may be here to stay, but not to rule.

A few new data storage technologies are currently getting attention, in particular graph databases such as AllegroGraph and Neo4j that allow to “structure on the fly” by using a multi-relational graph data model.
