Figure 2. Counts Within Quintiles for 12 Low-Value Services in 4 Identified Hospital Clusters.

Figure 2.

A, Cluster profiles for hospitals with capacity for 7 or more services (cohort A, N = 2415 hospitals) in reference to the following procedures: knee arthroscopy, vertebroplasty, IVC filter, renal stent, hysterectomy, CEA, coronary stent, and spinal fusion. B, Cluster profiles for hospitals with capacity for 7 or more services in reference to the following diagnostic tests and imaging: electroencephalogram (EEG) (syncope), EEG (headache), carotid artery imaging (syncope), and head imaging (syncope). Bars show the counts of quintiles of the normalized overuse hospital rates for each service across the 4 clusters. CEA indicates carotid endarterectomy; IVC, inferior vena cava.
