Cutoffs of MRCI and Number of Medications for Unplanned Hospital Admission, Derived From Receiver Operating Characteristics Curve Analyses

	Cutoff	Sensitivity	Specificity	Youden Index	AUC ROC Curves
MRCI	14	0.46	0.75	0.20	0.641
Number of medications	5	0.53	0.70	0.23	0.644

Notes: AUC = area under the curve; MRCI = Medication Regimen Complexity Index; ROC = receiver operating characteristics.
