Clinicians can ‘chat’ with medical records through new AI software, ChatEHR

In a lot the identical method individuals can “chat” with giant language fashions like GPT-4, Stanford Well being Care clinicians can now work together with a affected person’s medical information by means of an AI-backed software program referred to as ChatEHR.

The expertise, at present in a pilot stage, allows them to ask questions on a affected person’s medical historical past, mechanically summarize charts and carry out different duties. ChatEHR makes use of data from a person’s well being information to offer its response.

“AI can increase the apply of physicians and different well being care suppliers, however it’s not useful except it is embedded of their workflow and the data the algorithm is utilizing is in a medical context,” stated Nigam Shah, MBBS, Ph.D., chief knowledge science officer at Stanford Well being Care, who led the crew in growing the expertise. “ChatEHR is safe; it is pulling straight from related medical knowledge; and it is constructed into the digital medical document system, making it straightforward and correct for medical use.”

The software program has been in growth since 2023, when a crew of Stanford Medication researchers led by Shah; Anurang Revri, vp and chief enterprise architect for Stanford Well being Care’s Know-how and Digital Providers; and others acknowledged the potential of enormous language fashions and have been impressed to create one thing helpful for clinicians.

“ChatEHR opens up a brand new method for clinicians to work together with digital well being information in a extra streamlined and environment friendly method, whether or not that is asking for a abstract of all the chart or retrieving particular knowledge factors related to the affected person’s care,” stated Michael Pfeffer, MD, chief data and digital officer for Stanford Well being Care and the College of Medication, who helped lead the event and integration of the software program.

“It is a distinctive occasion of integrating LLM capabilities straight into clinicians’ apply and workflow. We’re thrilled to convey this to the workforce at Stanford Well being Care.”

Quicker search, abstract and knowledge gathering

At present, the software program is accessible solely to a small cohort of people at Stanford Hospital—33 physicians, nurses, doctor’s assistants and nurse practitioners—who’re monitoring its efficiency, refining its accuracy and enhancing its utility.

“Making the digital medical document extra user-friendly means physicians can spend much less time scouring each nook and cranny of it for the data they want,” stated Sneha Jain, MD, a medical assistant professor of drugs who has been an early person of the expertise. “ChatEHR can assist them get that data up entrance to allow them to spend time on what issues—speaking to sufferers and determining what is going on on.”

When clinicians entry the device, they’re greeted with: “Hello, 👋 I am ChatEHR! Right here that will help you securely chat with the affected person’s medical document.”

At that time, they will kind in a slew of questions concerning the affected person: Does this particular person have any allergic reactions? What does their newest ldl cholesterol take a look at present? Have they’d a colonoscopy? Had been the outcomes regular?

ChatEHR will not be meant for medical recommendation, Shah stated. The software program is an information-gathering device that may expedite the method and, ideally, save time. All choices keep in well being care specialists’ arms.

Past a single search, ChatEHR can speed up lots of the time-consuming duties which can be a part of a health care provider’s on a regular basis workload. Jonathan Chen, MD, Ph.D., a hospital doctor and an assistant professor of drugs and of biomedical knowledge sciences, famous that when a affected person involves the emergency room, the admitting physician has to shortly work out the way to assist them.

“It isn’t simply the chest ache they’re having in that second that issues—it is their complete story, what led as much as this second. All their prior historical past is related. What drugs have been they on, what uncomfortable side effects did they’ve, what surgical procedures happened and the way did that have an effect on them?” he stated. “It is a ton of labor to return and discover all of that data throughout a time-sensitive case, so rushing up that course of can be an enormous assist.”

He added that ChatEHR might be useful in some switch circumstances. Sufferers who’re transferred to Stanford Hospital for extra superior care usually arrive with a big packet of data, typically lots of of pages lengthy.

“All of that medical historical past is essential, however entering into chilly and sifting by means of that may be a big raise,” Chen stated. “Having ChatEHR boil that down right into a related abstract would make that course of smoother.” And, he stated, it isn’t simply high-level summaries that ChatEHR offers—the doctor also can ask probing follow-up questions to raised perceive the affected person’s historical past.

The crew can also be constructing out one thing they name “automations,” or evaluative duties based mostly on a affected person’s historical past and document. For instance, the crew has created an automation that may decide whether or not it is acceptable to switch a affected person to the Stanford Medication-affiliated Sequoia Hospital affected person care unit, which provides extra affected person rooms.

“That automated analysis saves us the executive burden of sifting by means of affected person data and helps us shortly decide if a affected person will be transferred, opening entry to care right here at Stanford Hospital,” Shah stated. He and others are engaged on different automations, which might decide eligibility for hospice care, for instance, or advocate further consideration post-surgery.

Persevering with the rollout

Shah and the crew will proceed evaluating ChatEHR’s use circumstances utilizing MedHELM, an open-source, versatile and cost-effective framework for real-world LLM analysis in medication. There are additionally different accuracy-ensuring options which can be in growth, comparable to citations that present clinicians the place bits of data got here from inside the medical document.

Because the expertise develops, the aim is to open ChatEHR to all clinicians who have a look at affected person charts. “We’re rolling this out in accordance with our accountable AI pointers, not solely making certain accuracy and efficiency, however ensuring we now have the tutorial sources and technical help accessible to make ChatEHR usable and helpful to our workforce,” Shah stated.
