The image of a doctor hunched over a keyboard, diligently documenting a patient encounter, may soon be a relic of the past. At Stanford Health Care, a growing number of physicians are leveraging artificial intelligence to streamline administrative tasks, allowing them to dedicate more time and attention to direct patient care. This shift isn’t about replacing doctors, but rather empowering them with tools that alleviate the burden of paperwork and enhance the quality of interactions.

For Christopher Sharp, MD, chief medical information officer at Stanford University Medical Center, the goal is simple: technology should facilitate, not hinder, the doctor-patient relationship. He believes AI offers a powerful opportunity to unlock valuable data within patient records and support clinicians in making informed decisions. The implementation of AI scribes and advanced data analysis tools represents a significant step towards realizing this vision, potentially reshaping how healthcare is delivered.

Stanford Health Care has been an early adopter of AI-powered solutions designed to transcribe and analyze medical histories, reducing the administrative load on physicians. One key tool summarizes key activities described in clinician notes, providing a concise overview of a patient’s care journey across different specialties. “It helps us say, ‘The medicine doctor has been treating them for diagnosis A and B, the urologist has seen them for diagnosis C, the neurologist seeing them for diagnosis E’—without having to go into each area of the chart manually,” explained Dr. Sharp. This summary includes citations, allowing for easy validation and deeper exploration of the data. Scientific American detailed these advancements in a recent report.

Beyond summarization, Stanford is also experimenting with “ChatEHR,” an open platform that allows clinicians to engage with patient data through a conversational interface. This allows doctors to quickly access specific information and delve deeper into a patient’s history with greater efficiency. For example, ChatEHR was used to rapidly screen patient charts to identify individuals eligible for a specific care pathway, a process that previously required extensive manual review. The AI-powered tool reduced the time required for this task from hours to minutes.

Ambient AI Scribes and Reduced Burnout

Perhaps the most impactful implementation has been the rollout of ambient AI scribe software. This technology listens to patient appointments and automatically generates medical summaries within a minute of the interaction’s completion. The AI scribe is designed to focus solely on clinically relevant information, filtering out extraneous details like conversations about hobbies. According to Dr. Sharp, the adoption of this tool has been “one of our biggest successes,” with clinicians reporting a significant reduction in cognitive load and improved overall wellness.

While initial expectations focused on increased efficiency – doctors potentially seeing more patients or leaving work earlier – the primary benefit has been a decrease in mental fatigue. Clinicians still spend time reviewing and editing the AI-generated documentation, but the burden of initial summarization has been lifted. This shift allows them to focus more on the nuances of patient care and less on the mechanics of documentation.

AI-Assisted Communication and Future Directions

The use of AI extends beyond documentation to patient communication. Stanford Health Care saw a 200 percent increase in patient messaging during the COVID-19 pandemic, creating a challenge for clinicians to manage the influx of inquiries. To address this, the organization implemented AI-generated draft responses, which clinicians then review and personalize to ensure accuracy and maintain their individual voice. This approach reduces the time spent crafting responses from scratch, allowing for more efficient and empathetic communication.

Looking ahead, Dr. Sharp envisions a future where AI technologies become even more integrated into the healthcare ecosystem, potentially extending their benefits directly to patients. He anticipates a scenario where patients can question questions and receive answers through AI-powered interfaces, bypassing the need to navigate complex patient portals. Further development includes experimenting with suggested orders – for example, an AI suggesting a chest x-ray based on a doctor’s verbal assessment – for review and approval.

The ultimate goal, Dr. Sharp emphasizes, is to improve patient outcomes. While definitive studies are still needed, he believes that reducing the cognitive burden on doctors could lead to more consistent and higher-quality care. He points to research suggesting that the time of day can influence care, with patients seen later in the day potentially receiving less attention to preventive care reminders due to physician fatigue. AI tools, he hopes, can help mitigate these variations.

Dr. Sharp recalls a particularly poignant moment that solidified his belief in the potential of this technology. During a conversation with a patient who had recently lost her sister, he focused on providing emotional support rather than taking notes. The AI scribe, however, captured the essential details of the patient’s family history, demonstrating the machine’s ability to perform tasks that complement, rather than replace, human interaction. “That was an example where the machine did what the machine does really well, and I did what a human does well,” he said.

As AI continues to evolve, its role in healthcare is poised to expand, offering the potential to transform the doctor-patient experience and improve the delivery of care. The ongoing research and implementation at Stanford Health Care provide valuable insights into the possibilities and challenges of integrating these technologies into clinical practice.

In a remarkable discovery that sheds light on ancient ecosystems, paleontologists have unearthed the oldest known fossilized vomit, or “regurgitalite,” dating back 290 million years. This specimen, found in a mountain valley of the supercontinent Pangaea, offers a rare glimpse into the dietary habits of early terrestrial predators.

The fossilized remains, which were published in January 2023 in the journal Scientific Reports, reveal that the predator consumed at least three distinct animals before regurgitating their bones. This finding not only highlights the predator’s feeding behavior but as well provides insights into the ecological dynamics of early land ecosystems.

Arnaud Rebillard, a paleontologist at the Museum für Naturkunde in Berlin, noted, “It’s kind of like a photograph of a moment in the past that is telling us about the animal that was living. Any data that we can discover about their behavior is extremely precious.”

Discovery and Analysis of the Fossil

The fossilized vomit, a lime-sized specimen, was discovered in 2021 at the Bromacker locality in central Germany. Researchers employed advanced scanning techniques to create 3-D models of the bones, which indicated they originated from the gut of a predator. A chemical analysis of the surrounding material revealed low phosphorus levels, confirming it was not fossilized fecal matter.

The analysis identified 41 bones within the regurgitalite, suggesting it came from a predator resembling modern monitor lizards, such as Komodo dragons. The two primary suspects are Dimetrodon teutonis, known for its distinct sail-like structure on its back, and Tambacarnifex unguifalcatus. Despite their reptilian appearance, both belong to a group called synapsids, which includes mammals and their extinct relatives.

Insights into Predator Behavior

Among the bones found, researchers identified two small lizard-like reptiles and a limb bone from a larger, herbivorous reptile. This variety in remains indicates that the predator was likely a generalist feeder, consuming whatever prey was available rather than specializing in a particular type.

Rebillard emphasized the significance of this discovery, stating, “We can literally say, for sure, that these three animals were living at exactly the same place and exactly the same time, maybe to the week or even to the day.” This level of specificity provides invaluable information for understanding the interactions within these ancient ecosystems.

Comparisons to Modern Predators

Today, many living predators, such as birds of prey and some reptiles, often regurgitate indigestible parts of their meals, including bones. While the exact reason for the ancient predator’s regurgitation remains unclear, it’s plausible that it either overate or needed to expel hard-to-digest material, similar to modern behaviors.

Fossils like this regurgitalite are crucial for piecing together the ecological puzzle of the past. Martin Qvarnström, a paleontologist at Uppsala University in Sweden, highlighted the importance of such findings: “We need fossils like this to really tie together how the ecosystem functioned and how the food webs were structured.”

Significance of the Bromacker Site

The Bromacker site is particularly valuable because it preserves a snapshot of early terrestrial ecosystems. During the Permian period, which this fossil dates back to, large herbivores began to dominate inland environments, leading to the emergence of new predators. Fossilized remains of dung and vomit are much rarer in these terrestrial settings compared to aquatic environments, making this discovery even more significant.

Rebillard reflected on the implications of this find, stating, “We’re talking about almost 300-million-year-old ecosystems. So to have such a temporal vision about this to the day they were living, in the same area and the same moment, is extremely fascinating.”

This discovery not only enriches our understanding of prehistoric life but also raises questions about the ecological interactions that shaped the evolution of terrestrial ecosystems.

Looking Ahead

As research continues, paleontologists hope to uncover more about the complex interactions within these ancient environments. This regurgitalite provides a rare opportunity to study the diets and behaviors of early predators, offering insights into the evolution of feeding strategies and ecological dynamics over millions of years.
