Detection of Chronic Patients
Vital due to increased risk of iatrogenic harm
Potential chronic patients could be identified by:
1. Size of paper records
2. Attendance records
Frequency
Regularity
Concordance
3. Hospital referral rates
4. Observation by staff
Medical
Nursing
Clerical staff – pattern spotting software
Linking Emotions with Physical Symptoms
“The good physician treats the
disease, but the great physician
treats the person.”
William Osler
Assessment of Chronic Patients
Once suspected of CMFSS…..
Identify 1 practitioner as the patient’s principle carer
Systematic assessment: case notes reviewed
patient seen for 1 or more extended consultations
Case notes:
often extensive
useful information within
compile a summary of case notes
evaluate accuracy of previously listed complaints
evaluate accuracy of previous diagnoses
include key investigations,personal & family circumstances
Appointment:
current problems & history explored
encouraged to talk about symptoms, associations, concerns
and state
patient & practitioner to finally agree a problem list
Non-Specific Symptoms
Often missed in assessment

Professional Meddling
On Psychiatry . . . Winston Churchill
“I am sure it would be sensible to restrict as much as
possible the work of these gentlemen, who are capable
of doing an immense amount of harm with what may
very easily degenerate into charlatanry. The tightest
hand should be kept over them, and they should not
be allowed to quarter themselves in large numbers
among Fighting Services at the public expense.“
On psychiatrists, in a letter to John Anderson,
Lord President of the Council (December 1942)
Common Chronic Ill-Health Complaints
• Low Back Pain
• Carpal Tunnel Syndrome
• Cumulative Trauma Disorders
• Tendonytis
• Repetitive Strain Injury
• Fibromyalgia
• Irritable Bowel Syndrome
• Chronic Fatigue
FORMS OF
CHRONIC PAIN
& FATIGUE
Those with heightened symptoms choose attributions to match concepts of
what is currently acceptable in medicine
External cause for illness preferred - patient becomes a helpless victim
Chronic Patient’s Attributions of Ill-Health
• Work
• Environment
Chemicals
Stress
Toxins
Virus
Allergies
• Traumatic injury
• Anatomy / Ergonomic

Somatization and Fashionable Diagnoses
Somatoform Disorders (DSM III category) “Somatization disorder”
Psychiatric diagnosis
Somatization
1. Rationalisation for psychosocial problems
2. Coping mechanism
3. Becomes a way of life

Dysautonomia Reactive Hypoglycemia

Chronic Fatigue Syndrome
Vague subjective multisystem complaints
Lack of objective lab findings e.g no organic cause
Semi-scientific explanations e.g “post-viral syndrome”
Symptoms consistent with Depression, Anxiety or general unhappiness
Linking Emotions with Physical Symptoms
• Patients with physical symptoms arising from psychological distress
• Some may not have made the link themselves
“Anxiety causes muscle tension. Muscle tension causes headaches”
• Don’t rush patient to understand
Start from their perspective
What do they think is causing physical problems (clues)
• Broaden agenda to where problems can be physical and psychological
Linking Emotions with Physical Symptoms
Which causes which?
Modern-Day Patients
Patients more involved in their own care than even before
The term “consultation” is disappearing
Mistrust of Medicine e.g. Shipman, Allit, Meadows cases
Less Mysterious and Powerful
Change in what is expected from practitioners…
…Has changed how practitioners view patients
Emphasis on
(1) risk reduction
(2) public health
(3) preventative behaviour
“Do you know about statistics?”
Some (older patients) still prefer to be told what the treatment will be
Skill is in achieving the correct balance for each patient
Terminology of Chronic Patients
Invokes many emotions in practitioners: despair
frustration
anger
“Heartsinkers”
“Difficult”
“Fat folders”
“Chronic complainers”
“G.O.M.E.R”
Inadvisable terms
Lose faith
Offensive
Complaints
“CMFSS”
Irritable Bowel Syndrome
Common digestive disorder
Functional syndrome
Traumatic life events, Personality
disorders, Stress, Anxiety, Depression
Somatization
Not a psychological disorder
Night-workers & Loners
Psychology important in how symptoms are perceived and reacted to
Can poor QoL Become a predictor of who will suffer in advance?
Chronic Fatigue Syndrome
• Non-specific subjective symptom
• Overlap with psychiatric diagnoses (66%)
• Chronic long-term inability and tiredness
• Both Physical and Psychological fatigue
• Most prevalent in white, middle class thirtysomething females
• Fatigue dominates activities and life

Compensation Neurosis
Pending litigation
Treatment results often poor
Some overt malingering
Exaggerated illness due to:
suggestion
+
somatization
rationalization +
distorted sense of justice
victim status
+
entitlement
Adverse legal / admin. systems
Harden patient’s convictions
With time, care-eliciting behaviour may remain permanent
Bellamy, 1997
Compensation Neurosis
Improvement in health.....
...may result in loss of status
Patient compelled to guard against getting better
Financial reward for illness is a powerful nocebo
Exacerbates illness
In a litigious society, will compensation neurosis become more widespread?
Accident Neurosis
• Failure to improve with treatment until compensation issue settled
• Accident must occur in circumstances with potential for compensation
payment
• Inverse relationship to severity of injury - Accident neurosis rare in cases of
severe injury
• Low socio-economic status favors accident neurosis
• Complete recovery common following settlement of compensation issue

What is the Motivation?
• Desire for attention
• Punish spouse / others

sex with spouse
work
military duty

Abnormal Illness Behaviour (Care Eliciting Behaviour)
• Disability disproportionate to detectable illness
• Constant search for disease validation
• Relentless pursuit of “enlightened doctors”
• Appeals to doctor’s responsibility
• Attitude of personal vulnerability and entitlement to care by others
• Avoidance of health roles due to lack of skills and fear of failure
• Adoption of sick role due to rewards from family, friends, physicians
• Behaviours which sustain the sick role - complaints, demands, threats

Psychological Consequences of Chronic Illness
Back Pain
• Distress
Money worries - Disablement
• Reduced Quality of Life
• Delay in seeking help
Fear
Denial
• Depressed / Anxious
• Increased somatic complaints
Pain
Fatigue
Breathlessness
Begins bad habit of seeking help too readily
Adjustment Disorder – commonest psychiatric diagnosis
Increased risk of suicide in early stages (of some conditions)
Behavioural Yellow Flags of Chronic Ill-Health
Indicative of long term chronicity and disability
Back Pain
•
Negative attitude – back pain is harmful and disabling
•
Fear avoidance – stops trying things – disability mindset
•
Reduced activity
•
Expects passive treatment to be better than active treatment
•
Tendency to low morale, depression and social withdrawal
•
Social / Financial problems
Somatization & Sick Role
The process by which psychological needs are expressed in physical
symptoms: e.g., the expression or conversion into physical symptoms of
anxiety, or a wish for material gain associated with a legal action.
1. Auxiliary social support
2. Rationalisation for failure
3. Gratification of nurturance
4. Manipulate interpersonal relations
5. Articulate distress: cry for help
6. Misinterpretation of anxiety / depression symptoms
7. Over-vigilance for significant symptoms
8. Avoids stigma with a physical cause
9. Over-attention reflects learned behaviour
10. Amplification and Negative Affectivity
11. Primary, Secondary and Tertiary gains
12. Unexplained physical symptoms in trauma victims (e.g. abuse)
Conclusion
• Somatization influenced by numerous factors
• Sick role resolves intrapsychic, interpersonal or social problems
• Fashionable diagnoses have considerable overlap
• Occupational and Environmental syndromes
• Non specific and subjective complaints
• Underlying depression, anxiety, and history of unexplained complaints
• Mass communication + support groups = fashionable way to solve distress
• Behavioural aspects of chronic patients – blame, refusal, over-reporting etc.
