Key Points
Evaluate how early point-of-care ultrasound affects emergency department length of stay and patient safety for adults with abdominal pain.
39,443 adult patients with nontraumatic abdominal pain
PoCUS performed within 1 hour of ED arrival
Analyses of ED LOS, costs, CT use, and outpatient disposition
Early PoCUS reduced ED length of stay by 16%
Increased odds of outpatient discharge by 50%
ED costs slightly increased by 4%
CT use remained unchanged with an odds ratio of 0.98
Increased odds of admission after return visit by 25% but reduced admission costs by 33%

Implication
A propensity score–weighted analysis shows early PoCUS improves ED length of stay in adults with abdominal pain, suggesting better resource utilization.
