Early imaging (e.g., X-ray, MRI) for acute low back pain without red flags is low-value. Why: Acute low back pain is typically self-limiting; early imaging does not improve outcomes and may lead to unnecessary interventions.
Unindicated imaging (e.g., USG abdomen, X-ray, MRI) for non-specific complaints is low-value. Why: Imaging should be guided by clinical indications; routine use for non-specific symptoms increases cost and radiation exposure without improving outcomes.
Ultrasound abdomen/pelvis ordered without a specific clinical indication is low-value. Why: Unindicated abdominal and pelvic ultrasounds are a recurring finding.
Imaging (X-ray, CT, MRI, or ultrasound) ordered without a clear clinical indication is low-value. Why: The imaging category is dominated by findings of unindicated imaging orders.
Ordering a screening ultrasound of the abdomen and/or pelvis without specific signs or symptoms pointing to abdominopelvic pathology is low-value care. Why: Unindicated screening ultrasounds can lead to incidental findings, patient anxiety, and a cascade of further unnecessary tests.
