What emergency medicine is researching now
The topics gaining the most ground, ranked by the PubDaily Trend Score: new research, stronger evidence, new trials and new guidelines. 291 topics in 22 specialties, updated 18 Oct 2026.
Monthly reportThe fastest-rising topics in medicine: October 2026Read →AI for ED triage
Machine learning and language models used to support triage in the emergency department.
Point-of-care ultrasound in the ED
Bedside ultrasound performed by emergency clinicians for diagnosis and procedures.
Key point: Focused transesophageal echocardiography should only be performed during advanced cardiopulmonary resuscitation or unclear shock when focused transthoracic echocardiography cannot clarify the issue.
High-sensitivity troponin pathways
Rapid rule-in and rule-out algorithms for myocardial infarction using high-sensitivity troponin.
Key point: The ESC 0/1-hour pathway did not increase 4-hour discharge versus 0/3-hour testing but was noninferior for discharge safety.
ED boarding and crowding
Patients held in the emergency department while waiting for an inpatient bed, and its effects.
Whole blood in trauma resuscitation
Transfusing whole blood instead of separate components in bleeding trauma patients.
Tranexamic acid in bleeding
Tranexamic acid in trauma and other acute haemorrhage.
Key point: Tranexamic acid does not affect all-cause mortality, functional outcomes, neurological impairment, or hematoma expansion in spontaneous intracerebral hemorrhage, despite reducing hematoma volume.

How the Trend Score works
Four signals
Growth in new papers (35%), growth in randomised trials, meta-analyses and systematic reviews (25%), new clinical trials registered (20%), and new guidelines and consensus statements (20%), each over the last 12 months against the 12 before.
A score out of 100
Each signal is ranked against every topic we follow, so a score of 90 means the topic is ahead of about 90% of them. Rising fast: 80 and above. Rising: 55 to 79. Emerging: fewer than 100 papers the year before, too few to rank.
What it does not tell you
More research on a topic is not evidence that a treatment works. Open a topic to read the papers and guidelines themselves. Counts come from PubMed and ClinicalTrials.gov.
