The TUG test is recommended as a quick, routine falls-screening modality for older patients [15,31,32]. It is easy to perform, has demonstrated high intra-tester

and inter-rater reliability [14], has shown construct validity [14,16,33], does not require Selleck 5FU specialized personnel, and is recommended by current guidelines [15]. Inhibitors,research,lifescience,medical In this ED study, TUG test results were related neither to balance plate testing nor to patient self-reported history of falls. In the regression models, the only near-significant relationship was between TUG testing and falls within the past 6 months. AUC for patient report falls was generally poor and with wide confidence intervals. The AUC was greatest for falls within the past month, 6 months, or year. For these time periods, TUG cutoffs could also be identified with a negative likelihood ratio sufficient to provide a small to Inhibitors,research,lifescience,medical moderate decrease in posttest likelihood of fall. The optimum TUG cutoffs of 12-15 seconds we found are consistent with those of other studies in community-dwelling elders [20]. Again, however, the results of the regression analysis and the wide CIs of the ROC curves indicate that there is generally Inhibitors,research,lifescience,medical poor agreement between TUG and patient reported falls history. In a study conducted among ED patients, Walker et al found that the TUG test was poorly predictive of ED Inhibitors,research,lifescience,medical revisit or admission, further supporting

its lack of a proven role in ED patients [34]. The lack of association between TUG and falls history in the ED is different than previous reports in community-dwelling elders where TUG was able to discriminate between those with a history of falls and non-fallers, correctly classifying approximately 70% of patients [35]. In another study, TUG had a high Inhibitors,research,lifescience,medical sensitivity and specificity of 87% in predicting past falls [20]. It may be that in the acutely-ill ED setting, the TUG test has different test characteristics

than in other community-dwelling elder populations. Based on out results and the results of Walker et al [34], the TUG test should not be adopted for ED use without validation in this specific population either alone or as part of a multifactorial risk assessment model. Our study was limited by the fact that, although eligible, no patients presenting with a fall were included only in the study cohort. Most previous studies of balance assessment have occurred in such patients, and this high-risk group is the recommended target for balance assessment [15]. ED patients who present with a fall have been shown to have worse performance on dynamic and static balance testing than non-fallers [7]. It may be that studying these modalities in elders presenting to the ED with a fall will improve the test characteristics. We did not classify falls and did not focus on patients with known risk factors for falling.
