Psychiatric Emergency Services (PES)

Type of Service

Crisis Intervention

Program Description

The Psychiatric Emergency Services (PES) is dedicated to providing quality, front line crisis intervention to individuals of all ages who are experiencing acute mental health problems that cannot be addressed by other services or informal support systems. People presenting to the ED with behavioural or mental health issues are seen in the PES. The team includes professionals from a number of disciplines including nursing, psychiatrists, social workers, psychiatric residents and learners from various disciplines. Clinical Services provided in the PES include: assessments of patients with acute crises; collection of collateral information; evaluation of patient's mental status to determine necessity and benefit of hospitalization; assessment of patients' risk to themselves and others; referral to inpatient and outpatient mental health services and community resources; interventions aimed at minimizing acute crises; crisis intervention and supportive psychotherapy; emergent and urgent pharmacotherapy; education regarding diagnosis, prognosis and treatment for patients, family members, and health professionals; if appropriate; rapid follow up visits for patients requiring close monitoring as outpatients. Model of service is clinical care, linking patients with needed services, focusing on educational activities based on best practice guidelines, as well as developing research activities using our extensive clinical database.

Access Information

A physician may refer a person to the Psychiatric Emergency Services (PES) in order to receive an assessment. To do this, a physician will have determined that the patient is in an acute crisis situation and would benefit from a psychiatric assessment. Patients who are initially seen and referred by their family physician can access the PES directly and generally do not require ED medical clearance. Patients presenting to the ED in acute crisis (without a physician's referral) are seen by the ED physician who then determines the necessity of a referral to the PES. Prior to initiating a referral to the PES, it is the referring physician's responsibility to ensure that the patient has received a medical assessment and acute medical problems have been ruled out.
