A

Might be long wait until you can xaminefor the effects of the exposure adhere might be a high number of drop outs so it can be expensive

40
Q

Describe retrospective cohort studies

A

Looks at historical information at evens of the past info immediately available

41
Q

What are he drawbacks of retrospective cohort studies ?

A

May be incomplete or unreliable

My be relying on peoples memories of distant events

42
Q

Data collected during a cohort study has sat done to it and why?

A

It must be manipulated to take into account the age ad sex distribution
It is then presented as standardised ratios

43
Q

Give an example of a cohort study?

A

Social class difference in ischaemic heart disease (IHD) in men

44
Q

Give some strengths of case controlled studies

A
  1. More suitable for rare diseases
  2. Can examine one effect but in several exposures
  3. Cheap and quick to conduct
45
Q

Give some disadvantages of case controlled studies

A
  1. Prone to bias in measuring exposure

2. may be difficult to elucidate cause and effect

46
Q

Give some advantages of cohort studies

A
  1. Suitable for rare exposures
  2. Can examine multiple effects of single exposure
  3. Can minimise bias in measuring exposure
  4. better at elucidation cause and effect
47
Q

Give some disadvantages of cohort studies

A
  1. Expensive and slow to conduct

2. Prone to drop out

48
Q

What do both cohort and can control have in common?

A

They both study test hypothesis about the possible causes and determinants of disease

49
Q

What are experimental epidemiological most appropriately used for?

A

They are the most appropriate mechanism through which casual relationship can be established

50
Q

What is experimental epidemiology based on?

A

Based on the principle of comparing outcomes between two groups which are identical in respects except that one grip is expose to a suspected casual agent or preventative treatment

51
Q

What is experimental epidemiology most useful in evaluating?

A

Most useful in evaluating new materials and drugs

52
Q

Give an example of an experimetnal epidemiology study

A

The vipeholm study which investigated how caries activity was influenced by inferring diets

53
Q

How is epidemiology used?

A

To help plan services part of oral health needs assessment

54
Q

What can epidemiology show us?

A
  1. The pattern and prevalence of disease by location over time

  3. Experiments to determine whether a risk or prevention is truly associated with a particular disease or with health
55
Q

What does epidemiology tell planers?

A

Tells planners and policy makers about the geographical distribution of disease and its pattern within the population itself

56
Q

What have surveys shown us regarding healthy care and equality

A

That there are many inequalities in health

57

A

They are conditions of daily living that determine a persons chance of maintaining good health

assessed the most effective evidence based strategies for reducing health inequalities in England.

62
Q

What did sir Micheal marmot review find

A
  1. There is a social gradient in health
  2. Health inequalities result from social inequalities
  3. To reduce the gradient actions must be universal, but proportionate to the level of disadvantage ‘proportionate universalism’

64

social determinants

65

demand

What was the key milestones in NHS dental care achieved in 2005

A

Choosing Better Oral Health

This describes a move away from a treatment focused dental service to a more preventive one

70
Q

What was the key milestones in NHS dental care achieved in 2006

A
  1. NHS dental contract

2. PCTs take over the statutory duty to monitor the oral health of their local populations

Q

What did NHS dental contracts aim to do

A

This aimed to focus dental services on prevention and give PCTs the flexibility to commission services appropriate to their populations’ needs and reduce inequalities in access.

72
Q

How did PCTs taking over the statutory duty to monitor the oral health of their local populations benefit dental care

A

informs the evidence-based commissioning of new services, and facilitates the best use of resources in improving dental health and reducing inequalities through oral health promotion programmes and wider public health measures.

73
Q

What was the key milestones in NHS dental care achieved in 2009

A

Delivering Better Oral Health advises population approach with advice and actions for all patients with additional interventions aimed at those patients at risk

74
Q

What was the key milestones in NHS dental care achieved in 2010
