Evaluating a new model of nurse-led emergency department mental health care in Australia; perspectives of key informants.

BACKGROUND: Mental health nurse services have existed in Emergency Departments (ED) for many years. However, there is considerable variation in the way these services operate, and no standardised model of care has been articulated.

AIM: To evaluate an extended hours nurse practitioner-led mental health liaison nurse (MHLN) service based in an ED in Sydney Australia.

METHODS: As part of a larger mixed-methods study, semi-structured interviews were conducted with a sample of ED patients and nursing, medical and psychiatry staff (N = 46). Newly recruited MHLNs were interviewed at the commencement and conclusion of the study period. This paper presents the qualitative component from the evaluation.

RESULTS: The new service was met with high levels of approval by patients and staff. MHLN team members were challenged by their new role but considered the service reduced waiting times, provided therapeutic benefits, and enhanced communication and support for emergency staff.

CONCLUSION: A nurse practitioner-led extended hours MHLN service embedded within the ED team structure provides prompt and effective access to specialised mental health care for people with 'undifferentiated health problems' and removes a significant workload from nursing and medical staff.
