Predictive Value of the Oakland Score in Emergency LGIB Cases
2025
A recent publication from CREST, summarized by Physician's Weekly.
The Oakland Score, designed to predict 30-day adverse events (AEs) in patients hospitalized with lower gastrointestinal bleeding (LGIB) and potentially identify candidates for safe discharge, had not yet been evaluated in the emergency department (ED) setting. Investigators concluded that the Oakland Score demonstrated strong predictive accuracy for patients with LGIB in the ED, but further prospective study was needed to determine its impact on clinical decisions, patient outcomes, and resource allocation.

The researchers did find some explanations for why unfractionated heparin is still so widely used for PE, despite no longer being the recommended option for most patients. Driving factors included “agnosticism regarding choice of anticoagulant, the inertia of learned practice, and therapeutic momentum after anticoagulation initiation,” the authors reported in study results published by JAMA Network Open on Jan. 3.
What's With All the UFH Infusions for Acute Pulmonary Embolism?
2025
Despite guidelines recommending other anticoagulants for people hospitalized with acute pulmonary embolism (PE), old habits and misconceptions have kept unfractionated heparin (UFH) the initial choice for many physicians in the U.S., according to one report.
"Addressing these misconceptions and changing clinical practice will require a multifaceted approach, including pragmatic trials of anticoagulation effectiveness and safety in clinical settings, targeted educational programs from professional societies, and adoption of evidence-based policies by institutional quality committees. Ongoing emergency care research using implementation science frameworks should be conducted to modernize anticoagulation choices and improve outcomes for patients with PE," the editorialists wrote.

2024
"In this pragmatic, stepped-wedge cluster randomized clinical trial conducted in a US community-based integrated healthcare system, a multipronged intervention including physician education, facility-specific audit and feedback, and CDSS access was not associated with a statistically significant change in OAC initiation on or within 30 days of ED discharge among patients with primary AFF," the authors wrote.
The study was led by David R. Vinson, MD, Department of Emergency Medicine, Kaiser Permanente Roseville Medical Center, Roseville, California, and was published online on November 6, 2024, in JAMA Network Open.
How Common Is Pediatric Emergency Mistriage?
2024
Only one third of pediatric patients were correctly triaged at emergency departments (EDs) in a northern California health care system, according to a multicenter retrospective study published in JAMA Pediatrics. Researchers also identified gender, age, race, ethnicity, and comorbidity disparities in those who were undertriaged.
“The ESI had poor sensitivity in identifying a critically ill pediatric patient, and undertriage occurred in 1 in 14 children,” wrote Dana R. Sax, MD, a senior emergency physician at The Permanente Medical Group in northern California, and her colleagues.
Can Electronic Decision Support Improve Acute Heart Failure Care in EDs?2024

Machine Learning to Improve Patient Triage in the Emergency Department
2024
The use of an emergency department triage tool informed by machine learning has the potential to improve predictions around patient health severity, leading to safer, higher quality, and more equitable care.
“We have rich data available in our EHR that can be used, in combination with presenting complaint and vital signs, to assist nurses with predicting patient acuity and resources needs in the emergency department. We can use these data to build and test prediction models targeting key outcomes, such as critical illness or hospital admission. Once refined and built into the EHR, these triage prediction models can be used in real time to help inform accurate sorting of patients on arrival. Carefully designed decision support that integrates risk estimates has the potential to improve the quality, safety, and equity of the care that we provide in the emergency department.”— Dr. Dana Sax

Outpatient Management of Acute PE Remains Underused
2024
Most patients treated in US emergency departments, even those considered low risk, continue to be admitted to the hospital.
"If I had a low-risk PE, I would appreciate avoiding the risks, costs, and inconveniences of an unnecessary hospitalization. Many diverse healthcare systems have implemented successful outpatient PE pathways. Common components include physician education, tools to help identify low-risk patients, and systems to facilitate patient access to anticoagulation and timely follow-up."

Data-Driven Approach Yields New Approach for Emergency Department Triage
2023
Dana Sax, MD, MPH of the CREST Network embraces a more objective and data-driven approach to ED triage
Emergency medicine involves a density of decision-making that exceeds that of any other medical specialty. Emergency physicians face high-stakes decisions related to diagnosis, treatment, and disposition with limited information and under intense time pressure during every shift. However, the first critical decision in the emergency department (ED) is often not made by physicians, but by emergency nurses. Within minutes of a patient’s arrival, these frontline clinicians are tasked with assigning triage acuity levels that dictate the course of care for individuals and shape the operational efficiency of the entire department.

Structured Surveillance Rarely Used for Patients with Subsegmental Pulmonary Embolism Despite Recommendations
2023
In addition to the low use of structured surveillance overall, modified CHEST criteria only identified a small portion of patients with subsegmental pulmonary embolism eligible to receive structural surveillance.
Despite guidelines from the American College of Chest Physicians (CHEST), the use of structured surveillance without anticoagulation for patients with subsegmental pulmonary embolism (PE) was low among the small proportion of patients who were eligible, according to the results of a study published in the Journal of the American Medical Association.

Blood thinners still often used to treat patients with small lung blood clots
2023
Kaiser Permanente study finds few patients qualify for surveillance and few physicians recommend it
When a patient arrives in the emergency department with a blood clot in their lungs, blood thinners are typically the first line of treatment. But over the years, questions have been raised about whether the risks associated with blood thinners outweigh the benefits of giving these drugs to patients who have a very small blood clot in a narrow lung artery.

Emergency physicians correctly identify patients with lung blood clots who should be hospitalized
2023
Kaiser Permanente study finds doctors use factors beyond risk stratification tools to determine if a patient can safely be treated at home.
Most patients who develop a blood clot in their lungs — an acute pulmonary embolism — are seen in the emergency department, where a physician must determine if they should be hospitalized or can be safely managed at home. A new Kaiser Permanente study found that patients who have a high heart rate or blood clots involving both lungs are more likely to be seen as high risk and subsequently hospitalized, even if they are categorized as low risk on a commonly used risk assessment tool.

AAP Guidelines Help Detect Invasive Bacterial Infections in Febrile Infants
2022
The American Academy of Pediatrics (AAP) clinical practice guideline (CPG) for management of well-appearing, febrile infants can help detect invasive bacterial infections (IBI) without using C-reactive protein (CRP) and procalcitonin (PCT) with high sensitivity but low specificity, according to a study published online Dec. 9 in Pediatrics.
Tran H. P. Nguyen, M.D., from Kaiser Permanente Northern California in Roseville, and colleagues conducted a retrospective cohort study of infants aged 8 to 60 days presenting at emergency departments between 2010 and 2019 with temperatures ≥38 degrees Celsius who met the inclusion criteria for the AAP CPG. The infants underwent complete blood counts, blood cultures, and urinalysis.

Opinion: I almost died last year from a medical problem that was entirely preventable
2022
"It started one weekend in November 2021 with stomach cramping, a low fever, chills and vomiting. Soon it became clear I needed to go to the emergency room. By the time I got there, I had low blood pressure, an elevated heart rate, intense abdominal pain and a high white blood cell count.... With guidance from my pediatrician, my parents told the doctors to check for appendicitis. But since I was tender all over my abdomen — not just on my right side — the doctors ruled it out.... In the middle of the night, I was rushed to get an ultrasound that revealed I had a perforated appendix that was leaking a poisonous stream of bacteria throughout my internal organs.
Anupam Kharbanda, pediatric emergency medicine doctor at Children’s Minnesota, came up with what’s called the pARC (pediatric Appendicitis Risk Calculator) score to help assess a child’s probability of appendicitis, using variables such as sex, age, duration of pain, pain migration, white blood cell count and more.... The pARC score could be an important piece of changing diagnostic practices and saving lives."

Seeking the best tests for babies with fever
2022
Kaiser Permanente research suggests less invasive options for checking infants for infection. When a parent brings a young baby to the emergency department with a fever, the result is often a challenging medical balancing act. The doctors want to rule out a dangerous bacterial infection but without too many invasive tests that can be harrowing for both infant and parent. New Kaiser Permanente research offers insight into that balancing act, suggesting a national clinical guideline may not be ideal in all health care settings.
The study, published December 7 in Pediatrics, examined a 2021 clinical guideline issued by the American Academy of Pediatrics (AAP) for the evaluation of infants 8-60 days old with fever. The study finds that other protocols may actually work better in certain circumstances by requiring fewer infants undergo extensive further evaluation such as invasive lumbar punctures of the spine and treatments such as intravenous antibiotics and hospitalization.

Not all heart failure patients require hospitalization
2022
Kaiser Permanente researchers develop risk calculator to guide hospital admissions from the emergency department. A new risk calculator could help emergency department physicians determine which patients with acute heart failure should be hospitalized and which can safely be discharged and return home, new Kaiser Permanente research suggests.
The retrospective study, published in JACEP Open, included all 26,189 patients who had been treated in a Kaiser Permanente Northern California emergency department for acute heart failure between January 2017 and December 2018. This study suggests that hospitalization may not offer a survival benefit for low-risk patients.

Decision-support tool tied to increased outpatient management of PE
2022
A peer champion-led decision support intervention to increase outpatient management of pulmonary embolism (PE) was sustainable 4 years after implementation, a cohort analysis shows. The researchers suggest that their model could improve sustainability of practice change for other conditions and warrants further study.
As reported in JAMA Network Open, the study was conducted in emergency departments at 21 U.S. community hospitals that had previously participated in the original decision-support intervention trial 4 years earlier: 10 were intervention sites, 11 were controls. In that trial, decision support with champion promotion resulted in significantly higher outpatient management at intervention sites, compared with controls.

A decision support tool implemented in Kaiser Permanente Northern California emergency departments in 2016 has continued to help physicians safely discharge patients with an acute pulmonary embolism to their homes without harmful effects, a new Kaiser Permanente study shows. An acute pulmonary embolism is a blood clot that blocks blood flow to the lungs.
The study was published May 16 in JAMA Network Open. Researchers in Kaiser Permanente’s Clinical Research on Emergency Services and Treatments (CREST) Network developed and then initially evaluated the implementation of an online support tool, called RISTRA (RIsk STRAtification), in 2016. Their research showing the tool could be successfully implemented was published in 2018 in Annals of Internal Medicine.
