“…157 The Home, Education, Activities and Peers, Drugs and Alcohol, Suicidality, Emotions and Behaviors, Discharge Resources (HEADS-ED) was found to be reliable and accurate, with good concurrent and predictive validity for future psychiatric evaluation and hospitalization. 158 Horowitz et al 149,151,159 have performed several studies on ED suicide screening, most recently by using multiple logistic regression modeling to determine which suicide screening questions best screen for and identify occult suicidal youth. 150 A 4-question model was found to optimize sensitivity (97%; 95% CI, 91%-99%), specificity (88%; 95% CI, 84%-91%), and negative predictive value (99%, 95% CI, 98%-99%) for ED patients presenting with both psychiatric and nonpsychiatric conditions.…”
