What is CAM?

• Complementary and alternative medicine (CAM) includes a range of therapies not considered standard to Western (US) medicine.

• Complementary: use of these techniques in combination with conventional approaches

• Alternative: use of these techniques in lieu of conventional approaches

• Many treatments considered to be CAM in the US are considered conventional approaches in other parts of the world (e.g., acupuncture)

• Line between CAM and conventional changes over time– Example: relaxation training (including CAM techniques) is a standard component of

many conventional PTSD therapies

– Example: biofeedback commonly used to treat pain management skills

• Meditation• Mindfulness-Based Stress Reduction• Neuro-linguistic programming• Progressive relaxation• Qigong/tai chi• Reiki energy healing• Spinal manipulation• Traditional Chinese Medicine• Yoga• More…

State of the Evidence

• Current evidence base is very limited (but growing)• 2011 evidence review included 7 randomized controlled trials, most of

poor/fair quality:– 1 acupuncture (1 good quality)– 3 relaxation (3 poor quality)– 2 meditation (1 fair, 1 poor quality)– 1 massage (1 poor quality)

• Insufficient evidence to draw strong conclusions about the efficacy

• Insufficient evidence to describe other important components of treatment decision-making: safety, cost effectiveness, dosing, indications and contraindications, mechanisms of action, etc.

• Retention rates, when reported, similar to evidence-based approaches

VETERANS HEALTH ADMINISTRATION

State of the Evidence

• Highest quality evidence exists for acupuncture• Acupuncture > wait list control

• Acupuncture active treatment (group CBT vs individual CBT?)≐

• Strong conclusions cannot be reliably drawn on the basis of a single RCT (further study needed)

• Greatest breadth of evidence exists for relaxation• Findings mixed: some studies show modest effect, others show no effect relative to

active comparators

• Most studies small with significant design flaws that limit interpretability

8

VETERANS HEALTH ADMINISTRATION

State of the Evidence

• Evidence in support of meditation as adjunctive treatment generally positive

• Meditation > control (usual care)

• Usual care + meditation > usual care alone

• Meditation vs. active treatment ?

• Different types of meditation with different hypothesized mechanisms of action (further study needed)

VETERANS HEALTH ADMINISTRATION

Summary and Conclusions

• The umbrella of CAM approaches includes a broad range of approaches, not all of which may hold the same level of promise for PTSD

• Preliminary findings are mixed, but suggest that CAM therapies merit consideration and further research

• Current evidence does not support the use of CAM interventions as alternatives to current empirically-supported PTSD approaches or as 1st line approaches

• Current evidence points to possible use of CAM interventions as adjunctive interventions
