A Texas Tech health podcast reviewed research on clinicians’ use of an AI information platform, a model designed to predict severe fetal compromise during labor, and a proposed method for allocating donor hearts. The findings describe platform use and model performance, but the supplied report does not establish that AI improves care or provide enough detail to assess the allocation proposal’s effect.
A weekly medical podcast from Texas Tech University Health Sciences Center reviewed research on clinicians’ use of an AI-enabled medical information platform, a model for estimating fetal risk during labor and a proposed approach to donor-heart allocation. The discussion highlights growing use of clinical AI and possible tools for risk assessment, while stressing that evidence about effects on patient care and the details of the heart-allocation approach remain limited in the report.
The AI study, discussed by host Rick Lange, examined clinician use of OpenEvidence from January 2024 through June 2026. It included just under one million clinicians, more than half of them physicians, with the remainder including physician assistants and nurse practitioners. Together, users submitted 271 million queries, according to the podcast discussion.
Monthly active users rose from 355 in January 2024 to 703,000 by the end of the study period. Average monthly queries per active user increased from about 18 to 40. The discussion said younger clinicians, residents and fellows were more likely to use the platform, as were clinicians in oncology and hematology, internal medicine, and family medicine. About 52% of queries concerned clinical decision-making, especially treatment and management; diagnostic questions were comparatively uncommon.
The second research topic was a prognostic model intended to estimate the risk of severe fetal compromise at birth. As described by host Elizabeth Tracey, researchers combined known clinical risk factors with the first 20 minutes of fetal heart-rate monitoring at labor onset. The study was retrospective and involved developing the model using one dataset, training and testing it with another, and externally validating it with a third. The podcast also discussed work on a more equitable method of distributing donor hearts, but the supplied transcript excerpt does not give the study’s methods or results in detail.
AI Use and Labor Risk Assessment
The figures show that a clinical information platform can reach a large number of medical professionals in a relatively short period. That scale makes the unanswered question of accuracy and clinical impact consequential: clinicians may consult these systems while making treatment decisions, but usage counts alone do not show whether the answers are correct or improve patient outcomes.
A labor-onset model could, if validated and shown to be useful in practice, help clinicians identify pregnancies at increased risk earlier. The podcast described the model as potentially identifying risk before a problem emerges, but prediction is not the same as preventing harm. Any clinical role would depend on how well it performs in real-world settings and whether acting on its estimates leads to better care.
Donor hearts are scarce, so allocation methods can affect which patients receive transplants. A change in how organs are distributed could have substantial consequences for patients and transplant teams. The report’s limited description does not establish what the proposed approach changes or whether it improves fairness or outcomes.

Three Studies in One Review
The podcast, TTHealthWatch, is a weekly review hosted by Elizabeth Tracey, director of electronic media for Johns Hopkins Medicine, and Rick Lange, president of Texas Tech Health El Paso. Its October 24, 2026, episode ranged across medical research, including coronary revascularization as well as the three topics covered here.
For the AI discussion, Lange said OpenEvidence has content partnerships with major medical publishers and described its information as more up to date than UpToDate, a clinical reference whose articles are written and periodically updated. That was a comparison made during the podcast, not evidence in the supplied material that the platform is more accurate or produces better clinical decisions.
The labor model uses cardiotocography, commonly called CTG, which records fetal heart rate during labor. The researchers’ reported approach combines those early monitoring data with clinical risk factors rather than relying on the monitoring alone. The supplied source does not include the full study results, performance measures or patient characteristics beyond the podcast’s description of the datasets.
“It doesn’t address the accuracy of the information that was provided. It doesn’t address whether it altered patient care and whether it improved care at all.”
— Rick Lange, president of Texas Tech Health El Paso, in the TTHealthWatch podcast
Evidence Gaps in Clinical Impact
The AI study documented use but, according to the podcast, did not evaluate the correctness of responses, changes to clinical decisions or effects on patient care. It is not clear from the supplied report whether clinicians’ use was independently verified or how the platform’s answers were assessed.
The transcript excerpt does not provide the labor model’s numerical performance results, thresholds, or enough information to judge how well it may apply across hospitals and patient groups. The suggestion that it could flag risk hours before a complication is discussed, but the excerpt does not provide findings that confirm that timing or show improved outcomes.
For donor-heart distribution, the report names a more equitable approach but does not describe its rules, comparison group or measured results. The available material therefore does not establish whether the method would alter allocation decisions or improve access for particular groups.
Clinical Validation and Allocation Details
For the AI platform, the next evidence needed is evaluation of answer accuracy and whether use changes decisions or improves patient outcomes, questions Lange said the study did not answer. The supplied report does not identify a timeline or a planned follow-up study.
The labor model would need its performance results and external validation details examined before its practical value can be assessed. The podcast discussion does not specify whether a clinical trial or implementation study is planned. For donor-heart allocation, readers would need the full research findings and a clear account of how the proposal compares with existing allocation practices. No decision or implementation date is provided in the source material.
Key Questions
What did the AI-use study measure?
It examined clinician use of OpenEvidence from January 2024 to June 2026, including user numbers and query patterns. The podcast said it did not test answer accuracy or whether the platform improved care.
How many clinicians were using OpenEvidence by the end of the study?
The podcast reported 703,000 monthly active users at the end of the study period. The figure describes monthly users, not the number of clinicians shown to have used the platform throughout the entire study.
What is the labor model designed to predict?
It aims to estimate the risk of severe fetal compromise at birth using clinical risk factors and the first 20 minutes of fetal heart-rate monitoring after labor begins.
Does the report show that the model or AI platform improves outcomes?
No. The podcast says the AI study did not measure accuracy or patient-care effects. The supplied report excerpt does not provide enough labor-model results to establish improved outcomes.
What is known about the donor-heart proposal?
The podcast described a study examining a potentially more equitable way to distribute donor hearts, but the supplied material does not provide its allocation rules or results.
