Impact of Emergency Department Safety Planning on 30-Day Mental Health Service Use.

OBJECTIVE

The aim of this study was to examine the association between emergency department (ED) safety planning and subsequent use of mental health care among individuals treated in the ED for suicidal behavior and to determine whether subsequent use differed by patients' receipt of recent mental health care.

METHODS

Data from 130 hospitals, derived from a 2017-2018 national hospital survey, were paired with national health insurance data from 2,328 patients with suicidal behavior treated in the EDs of these hospitals. Rates of ED readmission, inpatient admission, and outpatient mental health follow-up care in the 30 days after discharge from the index ED visit were examined.

RESULTS

During the 30 days after discharge from the index visit, readmissions to the ED (18% vs. 22%) and inpatient admissions (12% vs. 15%) for suicidal behavior or other mental health issues were significantly lower among patients treated in the EDs that routinely implemented safety planning, compared with those that did not, respectively. Among patients who had not received mental health care within 30 days before the index visit, those treated in an ED implementing routine safety planning were about half as likely (adjusted risk ratio=0.60) as those treated in an ED without such planning to have an ED readmission.

CONCLUSIONS

Safety planning was associated with fewer subsequent ED and inpatient admissions among patients treated in the ED for suicidal behavior. The authors recommend that safety planning be universally implemented in EDs and included in routine outpatient care.
