ObjectivesPresent evidence regarding the predictive
value of psychosocial evaluation in chronic pain patients undergoing interventional procedures
Define the role of diagnostic and therapeutic interventional pain management procedures in an interdisciplinary pain management paradigm

Psychosocial BackgroundBiopsychosocial complexity of chronic pain
cannot be underappreciated41% with Axis I disorder200-300% increased association with
depression and anxietyCost of chronic pain treatment annually
exceeds $600 Billion annually

Fusion Versus Nonoperative Care for Chronic Low Back Pain Systematic review of randomized controlled trials18 Studies met inclusion criteria for the period 1990-
2010Beck Depression Inventory, Fear Avoidance Belief
Questionaire, Zung Depression Scale, Spielberger Trait Anxiety Inventory, and Distress and Risk Assessment Method
Patients with a personality disorder appear to respond more favorably to conservative management and those without a personality disorder more favorably to fusion
