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:
| Patient Disposition | ||
| HEARTSMAP Recommendations | Admitted (n=13) | Discharged (n=49) |
| Admit | 13 | 33 |
| Discharge | 0 | 16 |
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.
