Area under Receiver operating characteristic curve and prognostic values of brief geriatric assessment items and their combinations* for prolonged length of hospital stay† (n = 1254).

ROC: Receiver operating characteristic curve; PPV: Positive predictive value; NPV: Negative predictive value; LR+: Likelihood ration of positive test; LR-: Likelihood ration of negative test; TP: True positive; FP: False positive; TN: True negative; FN: False negative;*: Only three best models (i.e., highest value of ROC) by level (i.e., Low, intermediate and high risk) are shown;†: Defined being in the highest tertile of length of hospital saty (i.e.,>13 days);‡: Defined by a number of drugs taken per day above 4;§: Living alone without using any formal or informal home services and social help;¶: during the past 6 months;#: Inability to give the month and/or year;**: Only combination involving at least 10 participants were considered;††: Combinations described in previous published study (Beauchet et al. J Emerg Med. 2013; 45: 739–45).Area under Receiver operating characteristic curve and prognostic values of brief geriatric assessment items and their combinations* for prolonged length of hospital stay† (n = 1254).
