Q

What are the key features of the medical model?

A
  1. Normality = State of health is the absence of disease
  2. Abnormality = Ill health is based upon pathological changes
  3. Ill health is caused by biological misfortunes that are identified by signs/ symptoms and the process of diagnosis
  4. Cure is to restore to a healthy (normal) state
  5. Medical knowledge is exclusionary (the job of expects)
  6. Model is disease orientated and concerned with pathology

Q

What are the criticisms of the medical model?

Q

What is a 95% confidence interval?

A

P = prevalence N = total population

Definition:

95% confidence interval is the range in which we expect 95% of the results to lie; 95% certain that the true value lies within that range.

Importance:

Important because it adds power and weighting to results; allows understanding of how significant the results are

Interpretation:

Results that occur outside of this range (i.e. outside of the null hypothesis) are considered statistically significant; results that are not in the range are described at significantly different.

Therefore, can reject the null hypothesis.

Q

How would you calculate a confidence interval?

A

First calculate p, then the SE (which is a given equation.)

then: CI = p ± (1.96*SE.)

Standard error is a representation of sampling error.

Q

What is a P value?

A

A number somewhere between 0 and 1.

It is the probability of the data falling within the range.

If it is, <5% then reject the null hypothesis (there is a statistical significant difference)

But if >5% then accept the null hypothesis

A

Death certificate is issued by a doctor

Death is registered by an informant (normally relative) within 5 days

All information is entered to the register for Births, Marriages and Deaths

This is then sent to the Office for National Statistics (Mortality statistics)

26
Q

What information is on a death certificate?

What potentially useful information is not?

On a death certificate

Certifies the fact of death, Age, Place of death, Information on cause of death

Not on death certificate

Live births/1000 women in population.

Of childbearing age. (Aged 15-44.)

29
Q

How would you work out the total fertility rate?

A

The number of live babies that would be born if every woman lived to menopause and gave birth in accordance with the current, age-specific fertility rate.

30
Q

What are population projections?

What are they used for?

A

Forecast future population size and structure

Based on assumptions about fertility/mortality/migration

Used for:

Planning services

Allocation of resources

In the past: to see what has happened to the population

The present: to make sense of present activity

In the future: to predict what is going to change

31
Q

What are population estimates used for?

How would you work out the population estimate?

A

Estimate the population size and structure between census

Applies what is known on birth/deaths/migration to present

Census baseline + births – deaths ± migration.

32
Q

What are the pros and cons of a population estimate?

A

Pros:

More up to date than the census

More accurate than projections

Cons:

Less reliable further away from the census

Migration info isn’t great

Says nothing about future trends

33
Q

What data from the UK census is used by healthcare workers?

A

Population size and structure (young, old, ethnic minorities)

Services

Base population

Measure of material deprivation

Identify and target inequalities

34
Q

What are the pros and cons of population projections?

A

Pros:

Can aid in planning, more long term.

Cons:

Less accurate the further forward you go.

Unforeseen changes can render invalid.

35
Q

Why are population pyramids useful?

A

Useful in planning resources

Because they allow the comparison of different groups over time.

36
Q

Mortality

Morbidity

Determinants of health

37
Q

What are the key concepts of Client Directed Care?

A

Patient is treated how they they wish to be treated

Care is tailored to them,

Shared in the decision making

Hollistic.

38
Q

What are the 3 main principles of person centred care?

A

Personalised

Seeing the whole person, putting their needs first, as they define them.

Coordinated

Continued across episodes, time, from childhood to adulthood

Enabling

They are part of the decision making and are taught to manage their own condition

39
Q

Why is person centred care important?

A

Evidence of positive outcomes for patients

Better care satisfaction

Less emergency visits

Social and political drivers

Concurs with the ethical principles underpinning the duties of a doctor

40
Q

What are the social and political drivers of policy and practice developments around person-centred care?

A

Patient dissatisfaction with the NHS – survey evidence

Wider society – less hierarchical relationships

patients want to get involved

Spiralling economic cost of NHS – better outcomes will control costs

Recent reports on appaling care standards

Essentially its just better more compassionalte care

41
Q

What organisational system oversees the cancer registration system?

A

ONS - office for national statistics

Cancer diagnosis leads to registry on 12 registers in the west midlands

42
Q

What are the uses of the cancer registration system?

A

Evaluation of screening programmes

Clinical and epidemiological research

Planning services for prevention and care

43
Q

What are the pros and cons of the cancer registration system?

A

Pros:

Detailed up to date information

Record linkage to cancer deaths

Cons:

Expensive, access is hard due to confidentiality

44
Q

Outline the process of notification of infectious diseases

A

31 Notifiable diseases

eg. Chlorea, Botulism, plague, mumps.

Doctor suspects case of notifiable disease

Notifies the Local Health Protection Unit

Which then notify the Health protection agency (PHE)

45
Q

What are the uses of notification of infectious diseases?

A

Action to prevent further infection

Identiy outbreaks

Surveillance to monitor trends

46
Q

What are the pros and cons of notification of infectious diseases?

A

Pros:

Linked to other data

Increase in accuracy,

Routine national data that is returned weekly to HPA

Cons:

Poor or variable completeness of some diseases

Accuracy can be questionable due to diagnostic uncertainty

47
Q

What is NHS activity data?

Give some examples

A

Large amounts of information about the NHS activity collect for administrative and clinical purposes

Person centred care:

Common terminology in nursing and social science literature

Refers to relationships over time

Considers episodes as part of a life course experiences with health

Concerned with the evolution of peoples experienced health problems as well as disease

Uses coding systems that allow for specification of peoples health concerns
