What this trial studies

This initiative evaluates the impact of a randomized Our Practice Advisory (OPA) intervention on physician ordering behavior for Hemoglobin A1c (A1c) and Thyroid-Stimulating Hormone (TSH) tests. The OPA alerts providers when these tests are ordered within 30 days of a prior result, encouraging them to reconsider unnecessary repeat testing. By focusing on optimizing resource use and aligning test orders with evidence-based guidelines, the study aims to improve patient outcomes and inform broader clinical decision support strategies. The results will help determine if the OPA should be implemented across all patients and potentially extended to other laboratory tests.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have had A1c or TSH tests ordered within the prior 30 days during their inpatient or observation stays at UCLA Health System hospitals.

Not a fit: Patients who have not had a result for A1c or TSH tests ordered in the prior 30 days will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could reduce unnecessary testing and improve patient care by ensuring more appropriate test ordering.

How similar studies have performed: Other studies have shown success with similar clinical decision support interventions, indicating potential for positive outcomes in optimizing test ordering.
