15 Stigma and Barriers to Care

16 From the 2010 National Survey on Drug Use and Health

17 Stigma Kessler RC. J Clin Psychiatry. 2000;61(suppl 5):4-12. Lack of perceived need Perceived lack of effectiveness Fear of forced hospitalization Agree or Strongly Agree, % Men Women Want to solve on own Stigma Unsure where to go 49 40

Arch Gen Psychiatry. 2005;62: Major Depression Bipolar Disorder GADPTSD 65% 94% 86% 95% Patients Making Treatment Contact, % % 90% 7% contact within year of PTSD onset and 12-year median delay to first treatment contact

20 Psychotherapy

21 Psychotherapies SRSUBSTANTIALSOMEWHATUNKNOWN A Trauma-focused psychotherapy that includes components of exposure and/or cognitive restructuring; OR Stress inoculation training C Patient Education Imagery Rehearsal Therapy Psychodynamic Therapy Hypnosis Relaxation Techniques Group Therapy I Family therapy Web-Based CBT Dialectical Behavior Therapy Acceptance & Commitment Therapy From VA/DoD Clinical Practice Guideline for The Management of Post-Traumatic Stress (2010)

22 Level A Psychotherapy Choices Patients should be offered one of the evidence-based trauma- focused psychotherapeutic interventions that include components of exposure and/or cognitive restructuring; OR stress inoculation training. Choice should be based on symptom severity, clinician expertise, and patient preference, and may include: Exposure therapy (e.g., Prolonged Exposure) Cognitive therapy (e.g., Cognitive Processing Therapy) Stress management therapy (e.g., SIT) or Eye Movement Desensitization & Reprocessing (EMDR)

23 VA/DoD Guideline: Therapy Selection 1. Explain the range of available and effective therapeutic options for PTSD to all patients with PTSD 2. Patient education is recommended as an element of treatment of PTSD for all patients and family members 3. Patient and provider preferences should drive the selection of evidence-based psychotherapy and/or evidence-based pharmacotherapy as 1 st line treatment 4. Psychotherapies should be provided by practitioners who have been trained in that particular method 5. A collaborative care approach to therapy administration, with care management, may be considered

37 Complementary and Alternative Medicine

38 What is CAM? A group of diverse medical and health care systems, practices, and products that are not generally considered part of conventional medical. NCCAM website: nccam.nih.gov Natural Products Herbal medicines, dietary supplements, probiotics Mind and Body Medicine Meditation, Acupuncture, Yoga, Progressive Relaxation Manipulative and Body-Based Practices Massage therapy, Spinal Manipulation National Center for Complementary and Alternative Medicine

39 Other ways to Organize CAM Based on validity of proposed mechanism: 1) Consistent with current medical perspectives and understanding of pathophysiology 2) Unsure of mechanism for perceived benefit 3) Violates basic laws of physics/chemistry/biology Or Based on Modality Type: 1) Interventions (e.g. Acupuncture) 2) Care Delivery Method (e.g. Computer Based Therapy) 3) Personal Activities (e.g. Recreational Therapy)

40 Why is CAM Research so complicated? 1. Hypothesis development Design believable studies 2. Definition and Validation of Diagnosis Define PTSD using validated instruments Establish Chronicity of symptoms 3. Treatment Design Standardize the intervention 4. Measuring outcome Use established assessment tools to evaluate Include follow-up assessments 5. Interpreting Results Identify primary and secondary outcome measures prior to the trial
