PEER REVIEWED
A flow chart shows how the final sample was developed. Patients who died (n = 1,101), readmission encounters (n = 949), and patients with other exclusions (eg, oncology, nonclinical encounters) (n = 2,393) were subtracted from all patient encounters (n = 25,717) for a final sample of 21,274.
