Choosing wisely in emergency medicine: Early results and insights from the ACEP emergency quality network (E-QUAL).

PURPOSE

To characterize performance among ED sites participating in the Emergency Quality Network (E-QUAL) Avoidable Imaging Initiative for clinical targets on the American College of Emergency Physicians Choosing Wisely list.

METHODS

This was an observational study of quality improvement (QI) data collected from hospital-based ED sites in 2017-2018. Participating EDs reported imaging utilization rates (UR) and common QI practices for three Choosing Wisely targets: Atraumatic Low Back Pain, Syncope, or Minor Head Injury.

RESULTS

305 ED sites participated in the initiative. Among all ED sites, the mean imaging UR for Atraumatic Low Back Pain was 34.7% (IQR 26.3%-42.6%) for XR, 19.1% (IQR 11.4%-24.9%) for CT, and 0.09% (IQR 0%-0.9%) for MRI. The mean CT UR for Syncope was 50.0% (IQR 38.0%-61.4%). The mean CT UR for Minor Head Injury was 72.6% (IQR 65.6%-81.7%). ED sites with sustained participation showed significant decreases in CT UR in 2017 compared to 2018 for Syncope (56.4% vs 48.0%; 95% CI: -12.7%, -4.1%) and Minor Head Injury (76.3% vs 72.1%; 95% CI: -7.3%, -1.1%). There was no significant change in imaging UR for Atraumatic Back Pain for XR (36.0% vs 33.3%; 95% CI: -5.9%, -0;5%), CT (20.1% vs 17.7%; 95% CI: -5.1%, -0.4%) or MRI (0.8% vs 0.7%, 95% CI: -0.4%, -0.3%).

CONCLUSIONS

Early data from the E-QUAL Avoidable Imaging Initiative suggests QI interventions could potentially improve imaging stewardship and reduce low-value care. Further efforts to translate the Choosing Wisely recommendations into practice should promote data-driven benchmarking and learning collaboratives to achieve sustained practice improvement.
