What does an epidemiological approach to a health needs assessment involve?

A

Define problem

Look at the size of the problem – incidence/prevalence

Services available – prevention/treatment/care

Evidence base – effectiveness and cost-effectiveness
Models of care – including quality and outcome measures

Existing services – unmet need; services not needed
Recommendations

23
Q

Which factor of the health beliefs model has been shown to be the most important?

A

Perceived barriers

This is all about the patient having poor self-efficacy (i.e. not being able to stick to a behaviour change they have made)

24
Q

What are some criticism for the health belief model?

A

Doesn’t consider the influence of emotions and behaviour

Does not differentiate between first time and repeat behaviour

Cues to action are often missing

25
Q

What are some examples of cues to action which may influence behaviour change?

A

Cues can be internal or external

Internal = increase in pain, decrease in ADLs

External = reminders in the post, reminders for GP apts, pressure from families etc.

26
Q

What are some factors for poor compliance to medication? (3)

A

Side effects (warn them)
Comorbidities (esp. mental health/dementia)
Polypharmacy
Complex drug regimes
Poor understanding of disease state
Social factors – i.e. they have dependants/act as carers for someone else so they don’t prioritise their own health

27
Q

What is a cohort study? One limitation?

A

Prospective
Population free from disease initially
Follow up on exposed and non-exposed group and see what the outcome is

Limitation = very expensive

28
Q

What is the theory of planned behaviour?

A

Proposes that the best predictor of behaviour is INTENTION i.e. “I intend to give up smoking”

29
Q

According to theory of planned behaviour, what are the 3 factors that influence our intentions and give an example of each with reference to smoking cessation? (6 marks)

A

A persons attitude - e.g. I do not think smoking is a good thing

Subjective norms (the perceived social pressure to undertake the behaviour) – e.g. people who are important to me want me to give up smoking

Perceived behavioural control (a persons appraisal of their ability to perform the behaviour) – e.g. I CAN give up smoking

30
Q

What are some criticisms of the theory of planned behaviour?

A

Doesn’t take into account emotions

Relies on self-reported behaviour (i.e. people may lie)

Lack of temporal element (there is no timescale on it)

Assumes that attitudes, subjective norms and perceived behavioural control can be measured

31
Q

How would you help people acting on their intentions for the theory of planned behaviour?

A

Perceived control
Anticipated regret
Preparatory actions
Implementation intentions
Relevance to self

32
Q

What are the 6 stages of the stages of change model (aka Transtheoretical model)? Give an example for each

A

Pre-contemplation – haven’t thought about stopping smoking

Contemplation – thinking about stopping smoking

Preparation – goes to the doctor/pharmacy, gets a prescription for NRT/Champix to prepare them for stopping. Sets a stop date. Throws away cigarettes

Action – stops smoking on quit date, uses medications to help them

Maintenance – continues with abstaining from smoking by going for regular reviews, picking up more medication etc.

(relapse) – potential for relapse after a “trigger” type event

33
Q

What are some advantages of the stages of change model (aka TTM)?

A

Acknowledges individual stages of readiness

Accounts for relapse/allows patient to move backwards in the stages

Gives an idea of time-frame/progression (albeit arbitrary)

34
Q

What are some criticisms of the stages of change model (aka TTM)?

A

Not all people move through every stage

Change might operate on a continuum rather than through discreet changes

Doesn’t take into account values, habits, culture, social and economic factors

35
Q

What impact does social norms theory have on health behaviours?
Note - you can get a 6 marker on this question

A

Social norms = behaviours and attitudes that are most common in a group
One of the most important factors influencing behaviour
Sometimes belief or norms is different to actual norms – allows people who want to do high risk behaviours to think they’re just doing what everyone else is doing (but is often not the case)
Providing the truth about social norms could decrease high risk behaviours – e.g. only 20% of people smoke
However – DOESN’T work when the risky behaviour is the social norm (drinking alcohol, obesity)

36
Q

Why do patients continue high risk behaviours despite knowing the risks?

A

Unrealistic optimism**

Justifies behaviour with other things
Doesn’t have the willpower to stop

37
Q

What is meant by unrealistic optimism?

A

Theory for why patients engage in risky behaviours

Individuals continue to practice health damaging behaviours due to inaccurate perceptions of risk and susceptibility

i.e. they are aware of the risks but “don’t think it would happen to them”

38
Q

What are the factors of unrealistic optimism that influence people’s perception of risk?

A

Lack of personal experience with the problem

Belief that it’s preventable by personal action

Belief that if not happened by now, it’s not likely to

Belief that the problem is infrequent

39
Q

Give examples of how health promoting interventions can be applied at a population, community and individual level

A

Population level – cigarette and alcohol tax

Community level – introducing more cycle paths to make cycling safer, having to pay a fee for bringing a car into an area (London), building an outdoor gym in a particular town

Individual level – patient centred approach to care. The care responds to their individual needs

40
Q

What is the definition of domestic abuse?

A

Controlling, coercive, threatening behaviour, violence of abuse between those aged 16 or over who are or have been intimate partners or family members

Includes – psychological, physical, sexual, financial and emotional abuse

41
Q

Which tool can be used to assess domestic abuse?

A

DASH tool (Domestic abuse and Sexual Harassment tool)

42
Q

What do you do if you think someone is at medium/standard risk of domestic abuse?

A

In these cases it’s their CHOICE what they do

Give them contact details for domestic abuse services and let them decide what to do

43
Q

What do you do if you believe someone is high risk for domestic abuse?

A

Refer to MARAC/IDVAS wherever possible with consent

In HIGH RISK – you can break confidentiality if you don’t get their consent, but always try and get consent first

44
Q

What is HARK

A

The four HARK questions were developed as a framework for helping identify people who have suffered domestic abuse, and found to be a sensitive tool. This stands for:
Humiliation
Afraid
Rape
Kick

45
Q

How are most opioids excreted from the body?

A

Renal excretion

46
Q

Which opioid do 10% of the population don’t have the enzyme to metabolise it?

A

Codeine

47
Q

Which opioid do 10% of the population metabolise very quickly?

A

Codeine

48
Q

Which people in the population are codeine not prescribed to? What is the SE for taking it?

A

Infants
Pregnant women

SE - Resp depression

49
Q

Allodynia meaning

A

A pain response from a non-painful stimulant i.e. soft feather touch causing pain

50
Q

Central sensitisation meaning

A

A state in which the central nervous system amplifies sensory input across many organ systems i.e. when a hug or a pat on the back hurts someone

51
Q

What is the antidote to opioid toxicity?

A

Naloxone - give it slowly

52
Q

Define malnutrition

A

54
Q

What are the 3 core principles of the NHS?

A
  1. That it meets the needs of everyone
  2. That it is free at the point of delivery
  3. That it is based on clinical need, not ability to pay
55
Q

What is Health inequality?

A

The preventable, unfair differences in health status between individuals that arise from the unequal distribution of social, environmental and economic conditions within societies, which determine the risk of people getting ill.

56
Q

What is the inverse care law?

A

The principle that the availability of good medical or social care tends to vary inversely with the need of the population served.

i.e. The more you need health care, the less there is available
