Association between hospital-level diagnostic testing and admission percentage for patients with AGE at 34 US children’s hospitals. Association between hospital-level diagnostic testing and admission percentage for patients with AGE at 34 US children’s hospitals. The risk-adjusted mean testing count (open circles; right y axis) is strongly correlated with the risk-adjusted percentage admitted (bars; left y axis) (ρ = 0.74, P < .001). Each observation (bars and open circles) represents a single hospital and is adjusted for age, payor, and severity. Carrie H. Lind et al.
