Q

blood alcohol concentration

A

will peak 1hr after drinking on an empty stomach and will be removed at a rate of 15mg/100ml/hr
women have smaller blood volume & lower alcohol dehydrogenase in their stomach so more alcohol is absorbed before it is metabolised

Q

A

helps determine frequency of a disease within certain risk factors and can assess people’s risk of disease
can be used to evaluate effects of any interventions that have been used and will help with evidence based approaches to health measures

Q

incidence

A

number of new cases of a certain disease that are currently occurring

33
Q

methods used for sampling (4)

A
  1. simple random sample
  2. systemic sample - individuals selected at regular intervals from a population list
  3. stratified sample - ensures small sub groups are adequately represented in a sample
  4. cluster sample - use of groups as sampling units
34
Q

requirements of an ideal index

A
  • clear, unambiguous, non-subjective
  • correspond with clinically important stages of disease
  • indicate tx needed
  • within examiner’s ability
  • reproducible
  • not time consuming
  • acceptable to ptx
  • amenable to statistical analysis
  • allow comparison with other studies
    indices used to measure disease
35
Q

eg of index

A

DMFT - decayed, missing & filled teeth

36
Q

limitations of DMFT

A
  • if teeth XLA for reasons other than caries this is a misrepresentation
  • can be difficult to visualise interproximal areas
  • can be difficult differentiating fissure sealant from restorations
  • can be influenced by past disease activity
  • cannot be used for root caries
37
Q

what is a risk factor

A

an environmental, behavioural or biological factor confirmed by temporal sequence usually increasing probability of disease occurring
if absent or removed it reduces probability
both causes & determinants are considered risk factors for disease development

38
Q

cause

A

external agent which results in disease in susceptible individuals

39
Q

determinant

A

attribute or circumstance which affects liability of an individual to be exposed, when they will be exposed and to develop the disease e.g. socio-economic status

40
Q

confounding variable

A

particular type of extraneous variable which for some reason has been left uncontrolled. the result is that on looking at findings of an experimental study, rather than only one possible variable exerting influence on outcome, there are found to be others, which are said to be confounding the results

41
Q

3 common indices of risk

A
  1. absolute
  2. attributable
  3. relative
42
Q

absolute risk

A

most basic measure which gives incidence rates of a disease amongst people exposed to an agent, however it assumes no risk is incurred by those not exposed to the agent

43
Q

attributable risk

A

this is the difference between the incidence rates of both exposed and non exposed groups; this represents the risks attributable to a factor being investigated

44
Q

risk ratio

A

is a ratio of the incidence rate in the exposed group to the incidence rate in the non exposed group; this will measure the proportion of increase (or decrease) of disease in the exposed group while making allowances for the frequency of the disease amongst those not exposed to the harmful agent

45
Q

cohort study

A

a prospective study where a group of people who have not yet got the disease are recruited for a
study and their risk factors are assessed. They will be observed over a period of time to measure the
frequency of occurrence of disease among those exposed to a risk factor and those not exposed
frequency of occurrence of disease

46
Q

case control study

A

restrospective study in which people with a disease are compared to those free from disease and their histories traced to find out any exposure to suspect harmful agents
may be less robust that cohort studies as it depends on patient remember their risk factors
could be used for preliminary investigation of a hypothesis before being followed by cohort study if possible
risk ratio cannot be found so instead an odds ratio is found

47
Q

main study providing risk factors for dental caries

A

vipeholm study

48
Q

evidence levels for different types of studies in order from best to worst

A
  1. systematic cochrane review & RCT
  2. cohort
  3. case control
  4. case report / series
  5. narrative review, editorial
49
Q

case report / series

A

this is a report on a single patient or series of patients with an outcome of interest however there is no control group involved
they should be used for identifying a new disease outcome & hypothesis generation but they cannot be used to demonstrate valid statistical associations due to their lack of control group

50
Q

cross sectional study

A

observation of a defined population at a single point in time or time interval
this is where the exposure & outcome are determined at the same time
can be use for estimating prevalence of disease & investigating potential risk factors
disadv are that the causality may be vague & these factors can be easily confused with confounding factors; likely to be recall bias

51
Q

case control study

A

study of people with a disease and a suitable control group without the disease; they will then be asked if they had a particular risk factor to see whether it played any part in their disease - useful when looking at potential causes of a disease
causes can be easily confused with confounding variables, there may be recall & selection bias and selection of controls may not be suitable, may be incorrect time relationships between the two so exposure may not have occurred before the disease

52
Q

cohort study

A

group of individuals established then their exposure measured
they are followed up over a period of time & those that develop the disease are identified
useful for estimating incidence of a disease, investigating causes of disease, determining prognosis, timing & direction of events of disease

53
Q

issues with cohort study (5)

A
  1. controls often difficult to identify
  2. confounding variables likely to interfere
  3. blinding is difficult
  4. large samples are needed for rarer diseases
  5. very expensive & time consuming
54
Q

4 key design elements of RCT

A
  1. specification of participants (so the inclusion / exclusion criteria)
  2. comparison (control group)
  3. randomisation
  4. blinding
55
Q

specification of participants

A

must be unambiguous i.e. not open to interpretation e.g. ptx age / severity of disease

56
Q

comparison

A

RCT must have control group which gets the placebo

57
Q

randomisation

A

describes how subjects are allocated to treatments - researcher & participant must not be the ones to do the allocation as there would be bias involved
this means any participant has an equal chance of being in the placebo group as being in the drug group - this should be done via computer

58
Q

blinding

A

RCT should be double blinded - this means participant & researcher must not be aware of treatment given to patients; if they were aware this may influence the results

59
Q

risk ratio

A

aka relative risk
can be devised once RCT undertaken & will describe whether there is a change between the placebo group or not, and by how much of a change there is
e.g. drug group was 63% but placebo was 18% so 63/18 means risk ratio = 3.42

60
Q

confidence intervals

A

95% confidence interval used
if the final confidence interval contains 1 then there is insufficient evidence of a difference but if it doesn’t there is sufficient evidence there is a difference between the two
e.g. if risk ratio was 3.42 and confidence interval was 1.52-7.73 there was sufficient evidence the drug was effective

61
Q

systematic review

A

different RCTs pooled together to realise the risks or benefits of a particular treatment
explicit search strategy to include all papers without prejudice then removing those with a low quality of evidence
highlights where more evidence is needed & when enough has been produced
will also identify flawed studies

62
Q

meta analysis

A

optional part of systematic review; it combines the statistical results of studies for a pooled estimate of treatment effect across the studies

63
Q

6 dimensions of quality in healthcare

A
  1. person centred
  2. safe
  3. efficient
  4. effective
  5. equitable
  6. timely
64
