(Press-News.org) In the face of the alarming number of opioid-related deaths in the U.S., there have been national efforts to increase emergency clinician prescribing of buprenorphine, a medication used to treat opioid use disorder. In a new study published in JAMA, UCLA Health researchers report on the extent and success rate of such efforts in California.
Opioid-related emergency department (ED) visits, hospitalizations, and deaths have increased markedly since 1999, and the growing number of cases was declared a public health emergency in 2024. Combined psychotherapy and medication, either methadone, buprenorphine, or naltrexone, is the standard treatment for this condition. Buprenorphine works by binding to the opioid receptors on the cell’s surface in the brain; it reduces cravings and withdrawal symptoms but does not produce the euphoric feeling that other opioid drugs induce. BRIDGE, an organization dedicated to improving access to substance use disorder treatment, started a California-wide initiative in 2019 for EDs to begin prescribing buprenorphine for opioid use disorder with linkage to addiction treatment.
“For a lot of people who use opioids, the emergency department might be the only touch point they have with the healthcare system, so it’s a huge window of opportunity to make a difference,” said Dr. Annette Dekker, an assistant professor in the Department of Emergency Medicine at UCLA and first author of the study. “We start these patients on buprenorphine, but we have no way of knowing if they continue on that medication or not, so the study was driven from an interest in understanding patients’ trajectories after initiation in the ED.”
To conduct the study, the researchers analyzed data on buprenorphine prescriptions in the California Controlled Substance Utilization Review and Evaluation System from 2017-2022.
The study found that the number of emergency medicine clinicians who prescribed buprenorphine rose from 2% to 16% of all California buprenorphine prescribers and buprenorphine initiation prescriptions from the ED increased from 0.1% to 5%. “We're seeing this huge shift of prescriptions over a five-year period -- the efforts are working,” Dekker said. The study also found that at least one in three patients is filling a second buprenorphine prescription within 40 days of the ED initiation prescription and one in nine patients is receiving continuous buprenorphine prescriptions within a year of an ED initiation prescription.
“I’m very encouraged by the results,” Dekker said. “Nevertheless, the percentage of patients linked to continuous treatment is going down, which suggests to me that we need to keep investing in these connections to outpatient care from the emergency department, such as BRIDGE, and outpatient treatment capacity which can provide continuous treatment.”

New sensor can take any gas and tell you what’s in it
2025-02-19
Expert sommeliers can take a whiff of a glass of wine and tell you a lot about what’s in your pinot noir or cabernet sauvignon.
A team of physicists at CU Boulder and the National Institute of Standards and Technology (NIST) have achieved a similar feat of sensing, only for a much wider range of substances.
The group has developed a new laser-based device that can take any sample of gas and identify a huge variety of the molecules within it. It is sensitive enough to detect those molecules at minute concentrations all the way down to parts per trillion. ...
How the brain balances risk and reward in making decisions
2025-02-19
At a glance:
Study in mice offers insights into the brain circuitry underlying certain types of reward-based choices.
Researchers identified distinct groups of brain cells activated when animals anticipate a reward to be above average or below average for a choice.
The findings enhance understanding of human decision-making and how the brain balances risk and reward.
Every day, our brain makes thousands of decisions, big and small. Any of these decisions — from the least consequential such as picking ...
Jumbled proteins paint a bold target on the backs of brain tumors
2025-02-19
Immune therapy has transformed how cancer is treated, but many tumors continue to evade these treatments, thanks to their resemblance to healthy tissue.
Now, researchers at UC San Francisco have found that some cancers, like deadly brain cancer (glioma), make unique, jumbled proteins that make them stand out. These newly recognized cancer-specific proteins, or antigens, could speed the development of potent immunotherapies that recognize and attack hard-to-treat tumors.
The study, which was supported through grants from the National Institutes of Health, appears in Nature on ...
Liver injury in immune Stevens-Johnson Syndrome and toxic epidermal necrolysis: Five new classification types
2025-02-19
Introduction
First identified by Stevens and Johnson in 1922, SJS and TEN are now recognized as disorders with a continuum of severity, from milder forms (SJS) to the most severe (TEN). SJS/TEN is associated with multiple etiological factors, most notably drug-induced liver injury (DILI), making the identification of the responsible agent crucial for patient management. However, previous studies have lacked uniformity in diagnostic approaches, limiting the ability to draw clear conclusions about causality.
Epidemiology
The incidence of SJS/TEN varies across regions, with notable differences between studies. For instance, ...
MSU study: Socioeconomic factors, unpredictability complicate diagnosis of episodic disabilities, like epilepsy
2025-02-19
Any patient suffering from new or worsening medical symptoms hopes for a relatively quick and accurate diagnosis.
However, for many people with episodic disabilities — periodic or intermittent conditions like migraines, lupus, Crohn’s disease and epilepsy, in which the presence and severity of symptoms fluctuate — a swift diagnosis is not guaranteed.
New research from Michigan State University focuses on diagnostic delays experienced by people with one such condition: epilepsy, a neurological disorder characterized by unpredictable seizures that affects over 3 million people in the United States and 50 million worldwide.

Improving quality of life and end-of-life care: Standardizing goals of care notes in EHRs
2025-02-19
INDIANAPOLIS – It is important that a healthcare team is aware of and understands a patient’s goals of care, both medical and personal. But that information, if documented, typically is not placed in a standardized location and is difficult to find within a patient’s voluminous electronic health record (EHR).
A new study by researchers from Regenstrief Institute, the Indiana University School of Medicine and Indiana University Health presents the standardized goals of care note they developed, deployed and evaluated as a quality improvement initiative at ...
