This treatment guideline is intended to assist clinicians in the Behavioral Health department in treatment planning and service delivery for patients with Post Traumatic Stress Disorder (PTSD). It may also assist clinicians treating patients who have some of the signs and symptoms of PTSD but who do not meet the full criteria of PTSD. The treatment guideline is not intended to cover every aspect of clinical practice, but to focus specifically on the treatment models and modalities that clinicians in our outpatient treatment setting could provide. These guidelines were developed through a process of literature review and discussion amongst clinicians in the Behavioral Health department and represent a consensus recommendation for service provision for this disorder. The guideline is intended to inform both clinical and administrative practices with the explicit goals of outlining treatment that is: effective, efficient, culturally relevant and acceptable to clinicians, program managers, and patients.
