Q

What does the GMC say about age discrimination?

A

“You must not unfairly discriminate against patients or colleagues by allowing your personal viewsto affect your professional relationships or the treatment you provide or arrange…
This includes your views about a patient’s or colleague’s lifestyle, culture or their social or economic status, as well as the characteristics protected bylegislation: age, disability, gender reassignment, race, marriage and civil partnership, pregnancy or maternity, religion or belief, sex and sexual orientation.”

Q

What is a QALY and how do we calculate them?

A

QALY-based assessments involve assigning a utility value (between zero and one) to a state of health and then multiplying that value by the number of years expected to be lived in that state.
e.g. Smith: 5 (yrs) x 0.5 QALY points = 2.5 QALYs
Jones: 5 (yrs) x 0.8 QALY points = 4.0 QALYs
The total value helps determine resource distribution.

Q

What are some objections to QALY based assessments?

A

Difficulties relating to measurement and bias “pharmaceutical company funded studies were eight times less likely to reach unfavourable qualitative conclusions about drugs under investigation than comparable non-profit-funded studies”

Some object QALY-based assessments are unjust
Double-jeopardy objection
Does end of life care lose out??
Favours life years over individual lives

Q

What is the case for QALY based assessments?

A

Addresses primary purpose of healthcare, which is about maximising welfare (=combination of quality and quantity of life).
Also might seem to be motivated at the individual patient level
QALY-based assessments are already utilised widely, including by NICE

Q

What are the problems with insurance models?

A

Adverse selection- Private health insurance tends to be more expensive the more likely you are to need healthcare.

Moral hazard- A process whereby ‘insulating’ consumers from consequences of their actions increases demand.

Consumer moral hazard: taking extra risks as don’t pay for the consequence

Provider moral hazard: carry out un-needed work as will be paid anyway

21
Q

What are some reasons for market failure?

A

Don’t provide the efficiency we hoped for
Information asymmetry-supplier-induced demand
Monopolies and limited market entrants
Transaction costs- the costs of ‘doing business’
Externalities
Also can fail as markets may not provide fair allocations- as seen with Wales health care differences with England

22
Q

What are some responses the the reasons behind market failure?

A

Information asymmetry- Try and ‘empower’ and inform the consumer -Regulate
Monopolies and limited market entrants - ‘Any willing provider’ - Subsidise new entrants
Transaction costs - try to minimise complexity
Externalities

23
Q

What is economic evaluation?

A

Deals with inputs and outputs (costs and consequences)

Concerned with choices – resources are scarce so decisions have to be made

Evaluations aim to make these
choices explicit

24
Q

What are the basic steps of economic evaluation?

A

Identify
Measure
Value
Compare

25
Q

What is involved in an evidence based approach?

A

Question formulation
Literature search
Appraisal of evidence
Clinical decision

26
Q

What are some examples of decision and diagnostic support systems?

A

Reminder systems
Decision systems
Prescribing support
Condition Management

27
Q

What are some examples of reminder systems?

A 
Screening
Vaccination
Testing
Medication use
To ID risky behaviour
28
Q

How do diagnostic systems work?

A

Model individual patients against epidemiological data
Can match patient signs and symptoms to database
Can provide hypotheses or estimates of probability of different diagnoses
E.g. Ottawa ankle rules
E.g. Decision support for VTE

29
Q

What may hinder the use of computerised support systems?

A

Earlier negative experience of IT
Potential harm to doctor- patient relationship
Obscured responsibilities
Reminders increase workload

30
Q

What may help the use of computerised support systems in practice?

A

Self control of the system

If the clinician notices it helps during their practice

31
Q

What is the link between 5 a day advice and cancer?

A

Found increased cancer risk if eat less than 200g of fruit or veg per day, but no extra cancer protection after 400g per day. So based on a portion of 80g that gives 5 portions a day

32
Q

What are some problems with trying to measure diet?

A

Random error as peoples diets vary
Bias
Confounding
Homogeneity of exposure

33
Q

What is weird about beta carotene?

A

As a substance of its own it increases cancer risk but if consumed in a vegetable then the protective benefit of the vegetable outweighs the risk of that

34
Q

What are some health promotion messages relevant to cancer?

A 
Increase level of exercise
Dont gain weight in adulthood
Aim for healthy BMI
Maintain safe alcohol intake
Eat at least 400g of fruit and veg per day
Limit intake or red or processed meat
35
Q

What are some explanations for the higher alcohol mortality amongst lower socio-economic groups even though they consume less alcohol?

A

Lower resilience or confounding factors
Possibly more binge drinking
Difference in drinking histories
Differential access to health services

36
Q

How can alcohol harm others?

A 
Physically threatened
Kept awake due to noise
Emotionally hurt
Serious argument
Looking after someone harmed by alcohol
37
Q

What are some policy ideas to reduce alcohol related harm?

A

Reduce affordability of alcohol
Marketing regulations
Reducing hours alcohol is available

38
Q

Why are brief interventions regarding peoples alcohol use not really done much in primary care?

A 
Time
Attitudes
Impact on patient relationship
Skills and training
Links to community support services
39
Q

What is an outbreak defined as?

A

An incident where 2 or more people thought to have a common exposure experience a similar illness or proven infection

40
Q

The public health act allows exclusions from work of people who pose increased risk of GI infection spread, who does this refer to?

A

People with doubtful personal hygiene
People who work in food preparation
Health care workers who work with vulnerable people
Children in nursery or pre school

41
Q

The food safety act refers to what?

A

A place selling any food substance, even if have no dietary value e.g. chewing gum

42
Q

What is hazard analysis critical control point- HACCP?

A

Compulsory procedure within GMP covering all aspects of food production, distribution and storage. It looks at areas where possible food hazards could occur and implementing effective control procedures at each place to ensure food safety.

43
Q

What are some types of economic evaluation?

A

Cost effectiveness- benefit in natural units- life years
Cost utility- benefit in utility values- QALYs
Cost benefit- benefit in monetary values

44
Q

What does cost minimisation analysis involve?

A

Not a full form of economic evaluation
Know (or assume) health effects to be equal

Two possibilities:
Evidence suggests there is no difference in outcomes
Prior view that health effects are equal
Then we choose the least cost option

45
Q

What is cost effectiveness analysis?

A

Effects are measured in terms of the most appropriate
uni-dimensional natural unit.

Cost per unit effect

Examples:
Renal failure - cost per life saved
Screening for Down’s syndrome - cost per Down’s syndrome foetus detected

Straight forward to carry out. But hard to compare different things.

46
Q

What is cost utility analysis?

A

Effects are multi-dimensional

Combines life years gained with some judgment (or value or preferences) on the quality of those life years

Most popular measure:
quality adjusted life years (QALYs)CUA enables comparison of interventions that would be measured using different clinical outcomes

Enables a global health budget to be allocated more efficiently across different clinical areas
BUT
Is heavily reliant on the Quality Adjusted Life Year

47
Q

What is cost benefit analysis?

A

CBA the most comprehensive form of evaluation
Takes a societal perspective
All costs and outcomes are included
All costs and outcomes are measured in monetary units
Controversial – how do we assign money values to health outcomes?
How much is a life or outcome worth?
Needs a uniform value across all options for efficient allocation of resources
Results presented as an overall + or - £ or $ etc
Allows comparison across programmes with different health outcomes
Allows comparisons with non-health care interventions, so can be used to allocate a global budget

48
Q

What are some problems with cost benefit analysis?

A

How do we value a life?
How do we value a health outcome?
How do we value other societal costs e.g. time?
Difficulties mean very few CBAs are undertaken

49
Q

What type of food poisoning is caused by a gram -ve bacteria with a transmission period of 12-72 hours?

A

Salmonella

50
Q

What bacteria causes symptoms within 2-2 hours after eating and produces a toxin that is acid and heat stable?

A
