• So we also have “medically unexplained syndromes”

Q

do MUS persist for a long time

A 
Dutch primary care study (n=254) of patients with unexplained fatigue, abdominal or musculoskeletal complaints. 
• 43% still had unexplained symptoms 1
year later (Koch et al, 2009)
• People with lots of persistent MUS tend to consult the doctor a lot – “frequent attenders”

Q

what is the problem of MUS

A

it violates the biomedical model which conflates disease and illness

If (according to the biomedical model) illness is a sign of disease and a person is ill without a disease, what can be going on?

Q

• What does it mean for “psychological distress” to “come out” as bodily symptoms?

A

• There is scant evidence that having lots of bodily symptoms is related to denying emotional problems – in fact the opposite is true

21
Q

is distress common in people with MUS

A

MUS are often accompanied by psychological symptoms or distress
• Study of co-occurrence of MUS and psychiatric symptoms in large community
sample
• More MUS, greater likelihood of anxiety and depression symptoms. (Simon &
Vonkorff, 1991)

22
Q

More symptoms you have the more likely you are to also present with psychological symptoms

A

true

23
Q

why is medically unexplained unsatisfactory

A

“Somaizaion” is unsaisfactory
• “Medically unexplained” is unsaisfactory – Diagnosis by exclusion. Coninued concern ‘have we missed something?’; indicates failure of medical system. Paients can feel dismissed.

  • Symptoms are real. They are not imaginary, they are not made up.
  • Alternaive approaches try to explain theexperience of symptoms in terms of interacting biological, psychological and (to a lesserextent) social factors, and help people to manage them.
24
Q

what is a symptom

A

What is a symptom?
– Bodily sensaions (e.g. Dizziness, pain)
– Bodily signs (e.g. Raised temperature)
which are atributed to illness

25
Q

what is perception of bodily sensations

A

noticing sensations
attending to sensations
experiencing sensations

26
Q

what is the interpretation of sensations

A

Interpretaion of sensaions
– Context important
– Beliefs and personal models of illness, illness prototypes
– May use heurisics – e.g. stress, age - rule of thumb
– Interpretations afected by emotional factors - personal experiences- illness in the family - makes you think a certain way

27
Q

how does emotion interact with cognition

A

In the community, emoion is posiively correlated with physical symptoms e.g. faigue (Pawlikowska et al, 1994)

higher distress higher fatigue
bidirectional

28
Q

what are the ways emotion interacts with cognition

A

• Fear of being ill – more vigilant to bodily sensations
• Physical sensations of anxiety
– Sweating, shaking, dry throat, dizzy, nausea, stomach cramps, buterlies
• Physical sensations of depression
– Weight/appeite change, sleeplessness, early waking
– Tiredness, aches and pains

29
Q

is emotion positively correlated with physical symptoms

A

yes

30
Q

do MUS challenge the biomedical model

A

yes

31
Q

what is involved with the maintenance of symptoms

A

Cogniive and emoional processes are involved in the maintenance of symptoms

32
Q

are MUS common

A

Yes
Medically unexplained symptoms are a common reason to present to health care services • They can be long-lasing, disabling and very distressing to live with

33
Q

how are MUS managed in clinical practice

A

Many doctors don’t know what to do, so they
try
– ‘Reassurance’ (efecive for approx 24 hours; Lucock et al, 1997)

– Referral to secondary care departments
• 30-70% no physical pathology

– Physical investigaion
• e.g. blood tests, scans/x-rays, endoscopy, laparoscopy

– Symptomatic treatment
• e.g. analgesia, anibioics, anidepressants

  • Surgery
  • e.g. proporion of appendectomies have normal histology
34
Q

how do doctors explain MUS to patients - 3 ways

A
  1. rejecting
  2. colluding
  3. empowering
35
Q

what does rejecting explanations consist of and its implications

A

denies realits of symptom
implies imaginary disorder

unresolved axplanatory conflict
gp is distrusted with future symptoms

36
Q

what does colluding explanations consist of and its implications

A

gp sanction patients own explanation - ‘ i think your right i agree’

questioning gps openness and competence

37
Q

what does empowering explanations consist of and its implications

A

tangible mechanisms
excuplation
opportunity for self-management

Implicaions are:
– Legitimises paient’s sufering and removes blame from paient
– Allies GP and patient
– Allows for discussion of psychological features
– Empowering

38
Q

Consequences of current medical approach

A

• Excessive investigation and treatment
• Iatrogenesis* – e.g. unnecessary treatment - harm caused by healthcare
• Heightened awareness of symptoms
• The lack of an explanation causes distress
– Paient feels disbelieved
– ‘heartsink’ paients (O’Dowd, 1988)
• Breakdown of therapeuic relaionship

39
Q

what is the psychological approach to MUS

A

Based on the idea that beliefs (cognitions),emotions, and behaviour interact with the body to maintain symptoms

40
Q

what happens

A

bodily sensation
interpreted as symptom
rest - seek treatment - continued checking
worry
preoccupation- hypervigilance - bodily changes- sleep disturbance
bodily sensation

41
Q

what does CBT do

A

identifies paients’ interpretations of sensations and beliefs about symptoms (their explanatory models)

Helps patients to develop alternative models
– e.g. This pain is not indicative of disease
– I can manage it
– It is normal so I can live a normal life

Promotes behavioural changes (increasing acivity, reducing checking, help seeking) Behavioural changes improve symptoms
Symptom improvement feeds back into beliefs

42
Q

CBT change to model

A

normalised
reduction in worry
sleep better - less preoccupied- less diabled - fitter

43
Q

does CBT work

A

Systemaic review of 31 controlled trials (29 Randomised controlled trials) of cognitive behavioural therapy (CBT) for MUS

• 12 month improvement compared with treatment as usual (TAU) in:
– Physical symptoms
– Funcional status
– Emoional distress

44
Q

what are the issues in engaging patients in psychological therapy

A

• Disenchanted with medical care
• Suspicious of mental health services
• Beliefs that symptoms are caused by disease
• Feel symptoms are not believed
• It is important to be able to explain the rationale for treatment convincingly
- limited CBT trained therapists

45
Q

adaption of CBT to primary care - reattribution therapy

what are the 4 stages

A

Stages of Reatribuion Therapy
1. Feeling understood – Explore illness belief, respond to emotional cues

  1. Broadening the agenda – Exploraion of emotional factors
  2. Making the link e.g. Stress response, muscle tensions - physical and emotional relationships
  3. Collaboraing on a treatment or management approach
46
Q

does reattribution therapy work

A

improvement in patient satisfaction
decrease in somatizing beliefs
no benefit of reduction in healthcare use
less likely to believe the cause of symptom was purely physical

47
Q

trained GPS

A

improved GP communication behaviour

48
Q

what is reattribution therapy

A

‘simpliied’ cogniive behavioural intervention (Reattribuion) can be delivered by non-
psychology trained health professionals in a way that is feasible and acceptable to patients and NHS
 But no studies have yet compared the full cost effeciveness compared with CBT.
 Unlikely to be as effective as full CBT for some patients with complex presentaions (Gask, 2011)

49
Q

does CBT have a strong evidence base

A

yes

50
Q

who is reattribution therapy delivered by

A

non-psychologist health professionals
