What about the 10% who cost us 90% - Another hedgehog maybe?
Return to Work After Lumbar Discectomy ( Schade et al 1999 ) Correlates with depression and workplace stress, not with indices of organicity.
Biopsychosocial consideration Parsons (1951) – The Sick Role Mechanic (1961) – Illness Behaviour Pilowsky (1969) - Abnormal Illness Behaviour Engel (1977) – “Biopsychosocial”
WHAT IS PAIN ? “An unpleasant sensory or emotional experience associated with actual or potential tissue damage, or described in terms of such damage.” (IASP 1979) Pain is always subjective Definition doesn’t tie pain to a stimulus Nociception is NOT equivalent to pain
The Multidisciplinary Approach (Presley and Cousins 1992) Holistic biopsychosocial assessment Rationalised organic treatment plan Psychological and social interventions A paradigm shift from traditional medical approach is required.
INTERACTIONS WITH ENVIRONMENT PAIN BEHAVIOURS SUFFERING COGNITIONS ATTITUDES BELIEFS PAIN PERCEPTION NOCICEPTION NEUROPATHY Fordyce and Loeser’s formulation
Yellow Flags Attitudes and Beliefs Belief that pain is harmful or disabling resulting in fear- avoidance behaviour Belief all pain must be abolished before return to work or normal activity Catastrophising, thinking the worst, misinterpreting bodily symptoms Behaviours Use of extended rest, disproportionate downtime Reduced activity, significant withdrawal from activities of daily living Report of extremely high intensity of pain on VAS Sleep quality reduced since onset of back pain https://www.cebp.nl/media/m24.pdf
Yellow Flags Compensation Issues Lack of financial incentive to return to work Delay in accessing income support and treatment cost, disputes over eligibility History of extended time off work due to injury or other pain problem Diagnosis and Treatment Experience of conflicting diagnoses or explanations for back pain Dramatisation of back pain by HP's, dependency on treatments, passive treatment Expectation of a techno-fix, eg, requests to treat as if body were a machine https://www.cebp.nl/media/m24.pdf
Yellow Flags Emotions Fear of increased pain with activity or work Depression (especially long-term low mood), loss of sense of enjoyment Anxiety about and heightened awareness of body sensations (includes sympathetic nervous system arousal) Feeling under stress and unable to maintain sense of control Family Over-protective or solicitous partner, emphasising fear of harm or catastrophising Socially punitive responses from spouse (eg ignoring, expressing frustration) Extent to which family members support any attempt to return to work Lack of support person to talk to about pr oblems https://www.cebp.nl/media/m24.pdf
Yellow Flags Work Frequent job changes, stress at work, job dissatisfaction, Poor relationships with peers or supervisors... Belief that work is harmful; that it will do damage or be dangerous Unsupportive or unhappy current work environment https://www.cebp.nl/media/m24.pdf
Yellow Flags Why would psychosocial variables influence pain and disability? Catastrophising directly influences pain intensity & pain-related disability (Turner, et al (2002) Pain; 98, 127-134) Psychological or social variables which function as threats, or are experienced as a loss of control, access standard sickness responses resulting in increased inflammation (Brydon, et al (2009)Brain, Behavior & Immunity 23; 217-224) Inflammatory proteins can have an exacerbatory role in pain (Wieseler-Frank, Maier, Watkins (2005) Neurosignals;14:166–174) Cycle - Cognitive & emotional responses during the experience of pain shaped pro-inflammatory immune system responses via interleukin-6 (Edwards, et al (2008) Pain; 140, 135-144)
Remaining at Work 20 public health workers at risk for developing chronic pain (taking sick days for pain probs) 10 TAU vs 10 CBT (4 x 1 hrs ACT) Dahl, Nilsson & Wilson, Behavior Therapy, 2004 Dahl, Nilsson & Wilson, Behavior Therapy, 2004
Case 1: TIM 44 y.o. software genius Referred by Rehabilitation Physician In context of escalating workplace pressue, gradual onset of neck, bilat. shoulder and arm (RSI-like) pain Pain began in context of escalating workplace stressors Workplace critical / unsupportive 20 months on WorkCover
Over prior 18 months he had been off work, receiving 1:1 physiotherapy input 1:1 exercise physiologist instruction 1:1 generalist psychology input
Investigations C. Spine MRI Brain MRI L Shoulder MRI Bilat nerve conductions Rheumatological screen Bone scan
Reason for referral: Failure to progress: Tolerances / capacities unchanged Rigid pain focus entrenched
Findings of Team Assessment Nil organic aetiology identified Marked physical deconditioning Exaggerated somatic preoccupation a/w ritualised safety behaviours High depression and anxiety scores Marked obsessionality Fear avoidance Poor self efficacy Oversolicitous partner Substances - 2 different benzos, 2 OTC analgesics, 2 types anti-inflammatory & EtOH
Recommendations from Team Assessment Reassurance Substance rationalisation Self-help text “Manage Your Pain” 1:1 psychology and physiotherapy – 3 sessions of each over 6 weeks
Progress Liked the book – he understood and felt inspired – but couldn’t progress Psychiatric assessment requested.
What next? Education re integrated activity of limbic and other brain centres with pain circuitry Discussion re neuroplastic exacerbatory processes Discouraged benzos Offered SNRI - declined Pregabalin commenced
Case 2 : Somatisation Long history of complaints High utilisers of health services Biomedical focus Excessive illness behaviour c.f. pathology Outcome issues - poor prognosis
Is chronic pain associated with somatization/hypochondriasis Is chronic pain associated with somatization/hypochondriasis. An evidence-based structured review (57 studies) Somatisation and hypochondriasis were both consistently associated with chronic pain Study evidence indicated a correlation between pain intensity and presence of somatisation and hypochondriasis Pain treatment improved somatisation and hypochondriasis Fishbain et al. Pain Pract. 2009 Nov-Dec;9(6):449-67
Case 2 : Pam 62 yo Referred by Pain Specialist Multiple morbidities including OA in hips, hands, neck and low back, haemochromatosis, osteoporosis (with compression fractures x2), macular degeneration, chronic constipation, stress incontinence, hypertension. Slim and frail-looking
Morphine sulphate SR 20 mg bd “Digesic” Diazepam 2.5 – 5 mg up to qid Aperients Nutritional supplements Procedures / “blocks” every 6-12 weeks
Reason for referral: Assistance sought with her distress - as demonstrated through her seeking of advice and reassurance via frequent phone calls (2-3 per week)
Background Younger of two daughters from wealthy family Sickly child – multiple hospitalisations for asthma Father was caring but busy Mother was just busy Teen years: Sister strong, successful and popular. Pam polite, unassertive, “a worrier”
Lots to worry about : Three adult offspring – 2 unwell (1 Alcoholic) 1 son-in-law unwell (Colitis) Seven grandchildren Very aging mother Fit but aging husband ….and of course herself too!
Case 3 : Brian 48 yo Surveyor Previously fit, very active professional man Actively involved with church Perfect family Perfectionist MBA 3 years ago Multiple orthopaedic (and visceral) injuries 6 weeks in hospital and 5 operations 8 weeks inpatient rehabilitation
Inpatient treatment Decompression/fusion L2/3 ORIF R. tibia/fibula ORIF R. humerus ORIF L. radius (distal) Repair hepatic laceration and bladder/ureter damage
Complaints Pain distracts him – can’t stop ruminating about pain and the idiot who caused it Cranky Impaired workplace function Exacerbation of (premorbid trait of) relative inflexibility. Had become intolerant Always tired Memory impaired
Reason for Referral Referred due to persistent pain (and his responses to it) causing disruption to interpersonal and workplace function – fear of losing job.
Not happy to take medication, fearing further compromise. Unable to obtain benefit from 1:1 CBT - Couldn’t focus -Too busy ruminating / distracting -Too sleepy -Neither time nor energy for behavioural tasks
Progress Brain MRI NAD ; neuropsych testing equivocal for ABI. Agreed to trial Nortriptilline 10 mg – unable to tolerate – sleep better BUT daytime compromise and exacerbated hesitancy Not making progress after 6 sessions Clin. Psych plus physio. instruction
Problems inherent with a big C approach to CBT Don't give more verbal rules to perfectionists!
