Q

What is an adverse event?

A

An injury caused by medical management rather than underlying disease

May be unavoidable (eg px being prescribed a drug for first time and having a reaction)
Or may be preventable (eg administering wrong dosage, operating in wrong part of body)

Q

In James Reasons Framework of Error, what are active failures and latent conditions?

A
  • active failures are acts that lead directly to the patient being harmed
  • latent conditions are predisposing conditions that make active failures more likely

Q

What is the Swiss cheese model?

A

Some holes are due to active failures and some holes are latent conditions. The holes are hazards and if they line up something can slip through and lead to a loss. The more layers of cheese (ie more safe guarding, defences and barriers) = less chance of hazards lining up

Q

What is the national tariff?

A

Scheme so that for each HRG, a set fee is paid from commissioners to providers.
The tariffs are based on typical costs, so efficient trusts can make a surplus but inefficient trusts can make a loss.
Never-events receive no payment.

Q

What are some critiques of evidence based practice?

A
  • RCTs not always possible (ethical grounds)
  • impossible to collate and maintain so much data
  • creates ‘followers’ out of clinicians when it may be more appropriate for them to use their initiative
  • requires good faith of pharmaceutical companies (publication bias, rare to see negative studies)
  • may be challenging and expensive to implement findings
  • inhibits autonomy of clinicians

Q

What is the the behavioural cultural explanation?

A

The idea that ill health is due to people’s decisions, knowledge and goals

(Ie people from disadvantaged backgrounds tend to engage in more health-damaging behaviours and vice versa)

But… Too simplistic, not everyone has ‘choices’ when there’s a lack of resources, behaviour is due to social processes and not simply individual choice

Enacted stigma is real experience of prejudice or discrimination
Felt stigma is the fear of enacted stigma

58
Q

What is the difference between the medical and social model of disability?

A

Medical model sees disability as a result of physical impairment to the patients body

Social model sees disability as the way that society is organised

59
Q

How can health be measured?

A

Mortality, morbidity and patient based outcomes (PROMs)

60
Q

What are PROMs and what can they be used for?

A

Patient reported outcome measures
Currently covers hip replacements, knee replacements, groin hernia and abdominal pain

Collected by all providers of NHS care and made publicly available
Assess health directly from the patients point of view, unlike morbidity and mortality
Can be used to improve clinical management of patients
Can compare between providers

61
Q

What is health related quality of life?

A

The functional effect of an illness, as perceived by the patient

62
Q

How can HRQoL be measured?

A

Either by quantitative or qualitative measures

Qualitative methods are useful but resource demanding and difficult to evaluate

Quantitative methods involve the use of instruments/ scales and can be generic (cover the whole population) or specific (to a certain disease/ site)

63
Q

What are some examples of specific and generic measure of HRQoL?

A

General: SF36, EuroQoL 5D

Specific: to site eg Oxford hip score, to disease eg asthma QoL questionnaire, to dimension eg Beck depression inventory

64
Q

What are some positives and negatives of specific instruments to measure HRQoL?

A

✅ relevant and sensitive

❌ limited comparison, can’t use on people who don’t have the disease

65
Q

What is SF-36?

A

Generic instrument to measure HRQoL
Short form 36-item questionnaire
Uses a 4 week recall period to score in 8 dimensions, then gives a score for each dimension (but cannot add up dimensions to give an overall score)

✅quick, easy to evaluate, population comparable
❌doesn’t produce a single index value

66
Q

What is EuroQoL 5D?

A

Generates a single index value for health status (unlike SF-36)
Full health is assigned a value of 1
Death is assigned a value of 0
Measures 5 dimensions, with 3 levels per dimension and the patient ticks the most appropriate box for each dimension

✅ very quick, reliable, valid, good population date

67
Q

What is screening?

A

Attempt to detect an unrecognised condition to distinguish between apparently well people who probably have a disease and those who probably do not.

68
Q

What are the 5 areas of criteria for screening?

A
  1. Condition (well understood, all cost effective primary prevention interventions implemented)
  2. Test (simple, safe, validated, accepted cut off, agreed policy on those who test +ve)
  3. Intervention (must be evidence intervention at pre-symptomatic stage leads to better outcomes than at symptomatic stage)
  4. Screening programme (proven reduction in morbidity and mortality, benefit outweigh harms, economically balanced)
  5. Implementation (adequate staffing and facilities, scientifically justifiable to public, quality assurance, informed choice for public)
69
Q

What types of bias could screening lead to?

A

Lead time bias
Length time bias
Selection bias

70
Q

What is lead time bias?

A

When early diagnosis falsely appears to prolong survival, when in fact px just knows they have disease for longer

71
Q

What is length time bias?

A

That screening is better at picking up slow growing cases rather than fast growing ones
These diseases detected are more likely to have a favourable prognosis and may never have caused a problem

72
Q

What is selection bias in screening?

A

The idea that screening studies are skewed by a “healthy volunteer” effect, because those who attend screening are more likely to follow health promoting behaviours eg good diet, exercise.

73
Q

What are some sociological critiques of screening?

A
  • nanny state idea that has to much focus on surveillance
  • victim blaming
  • feminism arguments (screening mostly aimed at women’s bodies so creates the impression that a woman’s body is inferior)
  • moral obligation (people have reported HCPs treating them as deviant if they refuse screening)
74
Q

What is sensitivity of a screening method looking at?

A

The proportion of people with the disease who test positive aka the detection rate
(The probability that a case will test positive)

75
Q

How can the sensitivity of a screening method be calculated?

A

= a / (a+c)

76
Q

What is the specificity of a screening method looking at?

A

The proportion of people without the disease who test negative (probability a non case tests negative)

77
Q

How is specificity of a screening method calculated?

A

= d /(b+d)

78
Q

If the same screening method is applied in the same way but in different populations, what effect will this have on its sensitivity and specificity?

A

They will not change (as they are characteristics of the test, not of the population)

79
Q

What is the positive predictive value (PPV)?

A

Probability of someone who tests positive actually having the disease

80
Q

What is positive predictive value strongly influenced by?

A

The prevalence of the disease

81
Q

What is the negative predictive value?

A

The proportion of people who are test negative who actually do not have the disease

82
Q

How is negative predictive value calculated?

A

=d / (c+d)

83
Q

What are the implications of a false positive result?

A
  • unecessary stress
  • may lead to lower uptake of screening programmes in future
  • unecessary use of invade diagnostic testing
84
Q

What are the implications of a false negative result?

A
  • falsely reassured

- not offered diagnostic testing that they would benefit from

85
Q

What are the three core principles of the NHS?

A
  • universal
  • free at the point of use
  • comprehensive
86
Q

What change did the 1983 griffiths report bring about for the NHS?

A

Gave an increasing role doe managers and gave the internal market (competition between hospitals)

87
Q

What does devolution mean?

A

That Scotland, Wales and Northern Ireland each have a differently organised NHS

88
Q

What is the current structure of the NHS, broadly?

A

Secretary of State -> department of health -> NHS England -> CCGs -> providers

89
Q

Who is responsible for most of the flow of the NHS budget?

A

CCGs

90
Q

How do NHS hospital trusts earn their income?

A

Through services that CCGs commission from them, and from the provision and undergrad and postgrad training

91
Q

What are clinical directorates?

A

Hospital trusts are organised into clinical directorates based on a speciality/ group of specialities eg radiology, women’s health
Each is led by a clinical doctor, as well as a lead nurse and non clinical doctor

92
Q

What is the role of clinical directorates?

A

To implement audits, protocols and manage medical education for their speciality

93
Q

What is a medical director?

A

Someone responsible for the quality of medical care, and communicates between the board and medical staff
Involved in approving job description, and carrying out disciplinary processes etc

94
Q

What is a profession?

A

An occupation able to make distinctive claims about its work practices and status
In healthcare, usually refers to occupations requiring registration

95
Q

What is socialisation?

A

The process by which professionals assume their professional identity during their education and training
Occurs during interaction with others (formal and informal curriculum)

96
Q

What is the self regulatory model?

A

Where a profession self regulates by determining who is to be admitted and who should remain licensed
Self regulation for doctors has now come to an end, GMC now controls registers

97
Q

What are the three elements of a profession?

A
  • can assert an exclusive claim over a body of knowledge/ expertise
  • establishing control over market and exclusion of competitors
  • establishing control over professional work practice
98
Q

What is explicit rationing?

A

Based on defined rules of entitlement

Circumstances of who gets treatment is widely expressed

99
Q

What is implicit rationing?

A

Allocation of clinical resources through individual decisions without the criteria for those decisions being explicit

100
Q

What are some drawbacks of implicit rationing?

A

Can lead to discrimination and inequalities
Doctors often unwilling to do it
Open to abuse

101
Q

What are some positives and negatives of explicit rationing?

A

✅ transparent, accountable, evidence based, equitable

❌ complex, assumes heterogeneity of patients and illnesses, impact on clinical freedom, patient distress, patient and professional hostility

102
Q

Which organisation provides guidance on whether treatments have be recommended and approved for use in that NHS?

A

NICE

Use evidence to assess clinical AND cost effectiveness

103
Q

What is meant by scarcity?

A

If demand outstrips resources, prioritisation is inevitable

104
Q

What is meant by efficiency?

A

Getting the most out of limited resources

105
Q

What is meant by equity?

A

Distribution of resources is fair

106
Q

The extent to which an intervention produces desired outcomes

107
Q

What is meant by utility?

A

The value an individual places on a health state

108
Q

What is meant by opportunity cost?

A

Once you have used resources is one way, you no longer have them available to use in another way

Measured in terms of benefits foregone (what would the same pot of money be able to buy, what are we now not able to buy)

109
Q

What is the difference between technical and allocative efficiency?

A

Technical: interested in the most efficient way of meeting a need

Allocative: choosing between one of the many needs to be met

110
Q

What is cost minimisation analysis?

A

When all outcomes are assumed to be equivalent, so focus is only on the costs (inputs)
Eg assume all hip prostheses improve mobility equally, so just choose the cheapest

Not often relevant as all outcomes are rarely equivalent

111
Q

What is cost effectiveness analysis?

A

To compare drugs/ interventions which have a common health outcome, measure in terms of cost per unit outcome eg cost per 5mm/Hg reduction in blood pressure

112
Q

What is cost benefit analysis?

A

All inputs and outputs are viewed in monetary terms
Can compare with interventions outside health care
But methodological difficulties eg how can you put a value on someone’s life

113
Q

What is cost utility analysis?

A

Focuses on the QUALITY of health outcomes produced/ foregone

Can compare interventions in QALY terms

114
Q

What is a QALY?

A

= quality adjusted life year

Uses a single index to incorporate both quality AND quantity of life

1 year of perfect health = 1 QALY, same as 10 years of 0.1 health

115
Q

How is quality of life methods for QALYs?

A

Uses EQ-5D (a generic instrument to measure HR-QoL

116
