7. How accurately can HEARTSMAP predict psychiatric admission?

During our HEARTSMAP pilot implementation at BC Children’s Hospital, we prospectively enrolled 62 patients presenting with mental health concerns to determine whether the tool could correctly predict which patients required a psychiatric admission. During the pilot implementation, users were asked to user HEARTSMAP to guide their assessment; however, the patient’s ultimate disposition was at the ED clinician’s discretion. The results are summarized below:

HEARTSMAP had 100% sensitivity, correctly identifying all 13 patients that required a psychiatric admission. HEARTSMAP’s specificity was 32%, recommending discharge for 16 of the 49 patients that were ultimately sent home. Nevertheless, our initial results at BC Children’s demonstrated a trend toward reducing wait times and the odds of requesting a psychiatric consult as a result of implementing HEARTSMAP.
