Q

Wilson and young screening criteria

A
Important disease
Understand cause
Recognisable early or latent phase
Simple, safe, precise and validated test
Acceptable to the population
Effective treatment with early detection, with better outcomes than late detection
Policy of who should be treated
30
Q

What can cause association

A
Bias
Chance
Confounding
Reverse causality
True causation
31
Q

Define bias

A

Systematic error which results in a deviation from the true effect of an exposure on an outcome

32
Q

Selection bias

A

Non response of certain groups, allocation bias.

Bias in which participants are selected

33
Q

Information bias

A

Measurement bias, observation bias, recall bias, reporting bias

34
Q

Publication bias

A

Trials with negative results less likely to be published

35
Q

Lead time vis length time bias

A

Lead time bias- looks like longer life expectancy because screening has found them earlier (ahead)
Length time bias- Less likely to see people with longer diseases (longer)

36
Q

Define confounding

A

Apparent association between exposure and disease. Independently associated with both disease and exposure.

37
Q

Bradford hill criteria for causation

A
Temporality (exposure before disease)
Reverse causality
Dose response
Strength of association
Reversibility
Consistency
38
Q

Planning cycle for health services

A

Needs assessment
Planning
Implementation
Evaluation

39
Q

Define health

A

A state of complete biomedical, social, physical, spiritual wellbeing and not merely the absence of disease

40
Q

Bradshaws needs

A

Felt need
Expressed need
Normative need
Comparative need

41
Q

Felt need

A

What the patient thinks they need

42
Q

Expressed need

A

What the patient tells you they need

43
Q

Normative need

A

What we say they need

44
Q

Comparative need

A

Differences in health services available to two populations

45
Q

Demanded and supplied but not needed

A

Antibiotics for viral

46
Q

Needed and supplied but not demanded

A

Smoking cessation

47
Q

Three approaches to a health needs assessment

A

Epidemiological approach
Comparative approach
Corporate approach

48
Q

Epidemiological approach

A

Use prevalence and incidence data

Doesnt take into account felt need

49
Q

Corporate approach

A

Takes into account stake holders
Takes felt needs into account
Blur need and demand
Influenced more by big dogs

50
Q

Comparative approach

A

Compares health access of two populations. Based on comparative need.

51
Q

Donabedian approach to evaluation

A

Structure
Process
Outcome

52
Q

Structure (in evaluation)

A

Building, staff, equipment

/1000 population

53
Q

Process (in evaluation)

A

What is done, how many seen or done

/1000 population

54
Q

Outcome (in evaluation)

A

Morbidity, mortality, disability, dissatisfaction

/1000 population

55
Q

Evaluation

A

Process which seeks to assess how a service systematically achieves its objectives

56
Q

Maxmells dimensions of quality

A

Effectiveness, efficiency, equity

Acceptability, accessibility, appropriateness

57
Q

Models of behaviour change

A

Health belief model
Theory of planned behaviour
Stages of change
(Nudging, financial incentives, motivational interviewing)

58
Q

Health belief model

A
Influencing patient perception to increase health promoting behaviour.
Susceptibility to ill health
Severity of ill health
Benefits of behaviour change
Barriers to taking action
59
Q

Theory of planned behaviour

A

Attitudes, subjective norm and percieved behaviour control influence intention. And then they will definitely change behaviour

60
Q

Transtheoretical/ stages of change

A

Precontemplation, contemplation, preparation, action, maintenance, relapse
Doesnt take into account personal

66
Q

Define suspected outbreak
