Is psychological assessment necessary for SCS patients? YES - 1998 Consensus statement Task Force of the European Federation of IASP Chapters (EFIC) - Gybels et al. (1998)‏ YES – 2004 Pain Society Guidelines “ data from the literature shows that a careful psychological screening leads to a significantly better outcome for SCS procedures”

“ data from the literature shows that a careful psychological screening leads to a significantly better outcome for SCS procedures”

Psychological Assessment of Candidates for Spinal Cord Stimulation for Chronic Pain Management. Expert Panel Report 2004 ( Beltrutti … North, Turk, Melzack & others) Pain Practice vol. 4 Sept. 2004 ) Found Personality per se is not predictive of outcome evidence supports psychological assessment, but it’s based on single centre studies, with different methodologies and small numbers therefore meta-analyses difficult recommend a brief battery with clinical interview

Why Assess ? Mental health problems common in Chronic Pain Chronic Pain and anxiety 15% to 50% (McCracken et al. 1999) Chronic Pain & depression 30% to 100% (Fishbain et al. 1997)‏ Chronic Pain and somatoform disorder ? (Bankier et al. 2000)‏

Chronic Pain and anxiety 15% to 50% (McCracken et al. 1999)

Chronic Pain & depression 30% to 100% (Fishbain et al. 1997)‏

Chronic Pain and somatoform disorder ?

(Bankier et al. 2000)‏

Psychological factors are associated with poor outcome Depression Catastrophising Anxiety are strongest predictors of disability at 2 yr follow-up Significantly better than pain or current level of disability (Sullivan 2001)‏

State vs. Trait factors Potential for clinicians to: overstate dispositional factors (neuroticism) and underplay situational factors Watch for psychopathologising a miserable situation Poor outcome could be reflection of poor management – not the patient’s fault !

Facilitate patient risk assessment Anxious people may lousy statisticians Do they understand the odds? How is the information framed ? Get them to contemplate their own possible response to various outcomes black & white or graded ?

Manage distress Work on their distress related or unrelated to pain, which if left untreated could interfere with SCS outcome Look for strengths in the patient as well as risk but watch out for Excessive stoicism

Breakdown of all MDT Recommendations

Result of SCS Trial: MDT vs No MDT (success => 50% pain relief)‏

Permanent implants - 6 month follow-up 90% reported ≥ 50% pain relief for both MDA and No-MDA pts MDA greatest impact on trial selection and allowing more complex patients who may previously have been declined, to be considered for SCS Some non-MDA patients have required PMP etc later (observed trend)‏
