Epidemiological, Comparative, Corporate
13
Q

- Dominant personalities may have undue influence
16
Q

- Define problem
- Size of problem: incidence, prevalence and mortality.
- Services available
- Evidence base - DATA
- Models of care
- Existing services
- Recommendations
17
Q
How does the Comparative approach to Health Needs Assessment work?

Compares the services received by a population (or subgroup) with others (may examine: Health status, Service provision, Service utilisation, Health outcomes)
18
Q
How does the Corporate approach to Health Needs Assessment work?
A
Not to do with corporations. It is about obtaining the views a range of stakeholders (Commisioners/Providers/Professionals/Patients/Press/Politicians) (Some may give their views even when not sought or seek to influence health needs assessments)
19
Q
Give a definition of Evaluation of Health Services
A
Evaluation is the assessment of whether a service achieves its objectives
Alternative:
Evaluation attempts to determine the relevance, effectiveness and impact of activities in the light of their objectives, in a systematic and obective manner
20
Q

A
- Structure (what is there - buildings/staff/equipment)
- Process (what is done - eg. no of patients seen @ A&E)
- Outcome (e.g. mortality, morbidity, QoL, satisfaction) [5D’s: death, disease, discomfort [QoL], dissatisfaction, diability
21
Q

A
Incidence = New cases, Denominator (number of disease free people at the start of the study), Time
Prevalence = Existing cases, Denominator, Point in time (point prevalence)
25
What is person-time and when is it used?
**Person-time is a measure of time at risk i.e. time from entry to a study to:**
* (i) disease onset,
* (ii) loss to follow-up or
* (iii) end of study
*It is used to calculate incidence rate which uses person-time as the denominator*
26
No of persons who have become cases in a given time period DIVIDED BY Total person-time at risk during that period
Incidence rate
27
What are the usual headings used when describing the epidemiology of a disease?
Time, Place, Person
28
What is the difference between absolute and relative risk?
* Absolute risk refers to the actual probability of an outcome occurring in a specific group regardless of any other factors.
* Relative risk on the other hand, compares the risk of an outcome between exposed and unexposed groups.
Absolute risk – gives a feel for actual numbers involved i.e. has units
(e.g. 50 deaths / 1000 population)
Relative risk – risk in one category relative to another i.e. no units
29
What is the difference between attributable and relative risk?
* Attributable risk: The rate of disease in the exposed that may be attributed to the exposure (a type of absolute risk (absolute excess risk))
(i.e. *incidence in exposed minus incidence in unexposed*)
* Relative risk: *Ratio of risk of disease in the exposed:unexposed*
(i.e. incidence in exposed divided by incidence in unexposed)
30
What is bias?
A systematic deviation from the true estimation of the association between exposure and outcome
31
What are the 2 main groups of bias?
1. Selection bias
A systematic error in: selection of study participants / the allocation of participants to different study groups
2. Information (measurement) bias
A systematic error in the:
- measurement of exposure + outcome
- collection, recall, recording and handling of information in a study
32
What are three sources of information bias?
**observer** (e.g. observer bias),
**participant** (e.g. recall bias),
**instrument** (e.g. wrongly calibrated instrument)
33
What is confounding?
where a factor is associated with the exposure of interest and influences the outcome
(but does not lie on the causal pathway)
34
6 'criteria' for causality
- **Strength of association** (magnitude of relative risk)
- **Dose-response** (the higher the exposure, the higher the risk of disease)
- **Consistency** (similar results from different researchers and different populations - using various study designs)
- **Temporality** (does exposure precede the outcome?)
- **Reversibility** (removal of exposure reduces risk of disease)
- **Biological plausibility** (biological mechanisms explaining the link)

Confounding
43
Select the term that is most appropriate to the issue described in relation to causation:
An association between postmenopausal oestrogen use and endometrial cancer was reported in some studies. However, it was subsequently argued that this might be due to increased diagnostic attention received by women with uterine bleeding after oestrogen exposure
Bias
44
What are population and high risk approaches to prevention?
- The population approach is a preventative measure
delivered on a population wide basis and seeks to
shift the risk factor distribution curve (eg. dietary salt reduction through legislation)
- The high risk approach seeks to identify individuals above a chosen cut-off and treat them (e.g. screening for people with high blood pressure and treating them)
45
(Rose) - What is the prevention paradox?
A preventative measure which brings much benefit to the population often offers little to each participating individual
46

A = Acceptable to population - not too invasive
P = Policy on who to treat is agreed on.
48
What is sensitivity?

correctly excluded by the screening test
- If you don’t have the disease, what is the chances the test will tell you you don’t?
50
What is positive predicted value?
the proportion of people with a positive test
result who actually have the disease.
51
What is negative predicted value?
the proportion of people with a negative
test result who do not have the disease

- Provides data on disease incidence/mortality/morbidity etc
- Can evaluate services by trends over time Quality of data variable
Disadvantages
- Data collected may not be the data required
- Does not consider the felt needs or opinions/experiences of the people affected
69
Advantages vs disadvantages of comparative approach to health needs assessment?
Compares the services received by a population (or subgroup) with others (may examine: Health status, Service provision, Service utilisation, Health outcomes)
Advantages
- Quick and cheap if data available
- Indicates whether health or services provision is better/worse than comparable areas (gives a measure of relative performance)
Disadvantages
- May be difficult to find comparable population
- Data may not be available/high quality
- May not yield what the most appropriate level (e.g. of provision or utilisation) should be
70
Advantages vs disadvantages of corporate approach to health needs assessment?
Advantages
- Based on the felt and expressed needs of the population in question
- Recognises the detailed knowledge and experience of those working with the population
- Takes into account wide range of views
Disadvantages
- Difficult to distinguish ‘need’ from ‘demand’
- Groups may have vested interests
- May be influenced by political agendas
71
What is lead time bias?
When screening identifies an outcome earlier than it would otherwise have been identified this results in an apparent increase in survival time, even if screening has no effect on outcome.
72
What is length time bias?
Type of bias resulting from an overestimation of survival duration due to the relative excess of cases detected that are asymptomatically slowly progressing, while fast progressing cases are detected after giving symptoms
OR
Because more aggressive diseases are asymptomatic for a shorter period, screening is more likely to detect slower progressing diseases, such as slow-growing tumours, which have a better prognosis, including longer survival
e.g.
pancreatic cancer vs breast cancer
73
Name a type of observational study [descriptive / analytical] and a type of experimental/interventional study?
Observational
- Descriptive (Case report / Ecological study)
- Descriptive and analytical (Cross-sectional)
- Analytical (Case-control / Cohort)
Experimental/Interventional study
- RCT
- Non-act
74
What is a cross-sectional study + Advantages vs Disadvantages?
Collects data at a single point in time to assess prevalence of RFs and disease iteself
Divides population into those without the disease and those with the disease and collects data on them once at a defined time to find associations at that point in time. They are used to generate hypotheses but are prone to bias and have no time reference.
Advantages
- Relatively quick and cheap
- Provide data on prevalence at a single point in time
- Large sample size
- Good for surveillance and public health planning
Disdvantages
- Risk of reverse causality (don’t know whether outcome or exposure came first)
- Cannot measure incidence
- Risk recall bias and non-response
75
What is a case-control study + Advantages vs Disadvantages?
These are retrospective studies that take people with a disease and match them to people without the disease for age/sex/habitat/class etc and study previous exposure to the agent in question. It is quick and inexpensive, but the retrospective nature shows only an association and data may not be reliable due to problems with patient’s memories.
Advantages
- Good for rare outcomes (e.g. cancer)
- Quicker than cohort or intervention studies (as the outcome has already happened)
- Can investigate multiple exposures
Disadvantages
- Difficulties finding controls to match with cases
- Prone to selection and information bias
76
What is a cohort study + Advantages vs Disadvantages?
These studies start with a population without the disease in question and study them over time to see if they are exposed to the agent in question and if they develop the disease in question or not. The advantage is that it is possible to distinguish preceding causes from concurrent associated factors. There is a lower chance of bias and absolute, relative and attributable risks can be determined. Requires controls to establish causation. It is prospective which can show causation where retrospective studies cannot.
Advantages
- Can follow-up a group with a rare exposure (e.g. a natural disaster)
- Good for common and multiple outcomes
- Less risk of selection and recall bias
Disadvantages
- Takes a long time
- Loss to follow up (people drop out)
- Need a large sample size
77
What is an RCT + Advantages vs Disadvantages?
patients are randomised into groups, one group is given an intervention, the other is given a control and the outcome is measured. Randomisation allows confounding features to be equally distributed. Confounding and biases are minimalized. They tend to be large and expensive and show volunteer bias. Ethical issues – is it ethical to withhold a treatment that is strongly suspected to be effective?
Advantages
- Low risk of bias and confounding
- Can infer causality (gold standard)
Disadvantages
- Time consuming
- Expensive
- Specific inclusion/exclusion criteria may mean the study population is different from typical patients (e.g. excluding very elderly people)
78
What is odds vs odds ratio + how to calculate?
Odds = the probability of an occurrence compared to the probability of a non-occurrence.
Odds = probability/(1-probability)
Odds ratio = ratio of odds for exposed group to the odds for the not exposed groups.
OR = {Pexposed/ (1 – Pexposed)}
{Punexposed/ (1 – Punexposed)}
OR can be interpreted as a relative risk when the event is rare
79
Incidence vs Prevalence vs Person time
Incidence – new cases, denominator, time
Prevalence – existing cases, denominator, point in time
Person time - measure of time at risk, i.e. time from entry to a study to (i) disease onset, (ii) loss to follow-up or (iii) end of study. Used to calculate incidence rate which uses person time as the denominator
80
What is incidence rate?
(No.of persons who have become cases in a given time period)/(Total person-time at risk during that period)
81
What is absolute risk?
gives a feel for actual numbers involved i.e. has units (e.g. 50 deaths / 1000 population)
82
What is attributable risk?
The rate of disease in the exposed that may be attributed to the exposure, i.e. incidence in exposed minus incidence in unexposed. Attributable risk is a type of absolute risk (absolute excess risk)
83
What is relative risk?
Ratio of risk of disease in the exposed to the risk in the unexposed, i.e. incidence in exposed divided by incidence in unexposed. Tells us about the strength of association between a risk factor and a disease
(ie RR is how many times more likely it is that an event will occur in the intervention group relevant to the control group)
84
Types of bias
Selection bias: a systematic error in:
- the selection of study participants
- the allocation of participants to different study groups eg. Non-response, loss to follow up, those in the intervention group (or cases) different in some way from the controls other than the exposure in question?
Information (measurement) bias: a systematic error in the measurement of classification of exposure or outcome
Sources of information bias:
- Observer (eg. observer bias)
- Participant (eg. recall bias, reporting bias)
- Instrument (eg. wrongly calibrated instrument)
Publication bias
85
What is reverse causality?
This refers to the situation when an association between an exposure and an outcome could be due to the outcome causing the exposure rather than the exposure causing the outcome
86
Criteria for causality (Bradford-Hill criteria)
• Analogy – similarity with other established cause-effect relationships
• Biological plausibility - biological mechanisms explaining the link.
• Coherence – logical consistency with other information
• Consistency – similar results from difference researchers using various study designs
• Dose-response - the higher the exposure, the higher the risk of disease
• Reversibility (experiment) – removal of exposure reduces risk of disease
• Specificity – relationship specific to outcome of interest
• Strength of association – the magnitude of the relative risk
• Temporality – does exposure precede the outcome
87

* A person's attitude to the behaviour
* The perceived social pressure to undertake the behaviour, or subjective norm
* A person's perceived behavioural control
Advantages: takes into account social influence
Useful for predicting intentions but not useful for actual behaviours
Example:
**Attitude** – I do not think smoking is a good thing
**Subjective Norm** – most people who are important to me want me to give up smoking
**Perceived Behavioural Control** – I believe I have the ability to give up smoking
**Behavioural Intention** – I intend to give up smoking

Give examples of types of error.
- Sloth = inaccurate documenting/not checking results for accuracy
- Lack of skill = not hving appropriate skills/training/practice
- Mistriage = over or under-estimating the severity of the situation
- Communication breakdown = unclear plan/not listening and explaining well
- Human factors: Bravado/timidity = working beyond competence/not having confidence to object
- Fixation/loss of perspective = focus on one diagnosis – confirmation bias
- Poor team working = some individuals out of depth and others underutilised
- Playing the odds = choosing the common and dismissing the rare
- Ignorance = lack of knowledge (can be conscious or unconscious incompetence)
- System error = environmental/technological/equipment failure\
116
Give TWO models used to describe situations leading to errors
- swiss cheese model
- Falling through the holes because there is failed or absent defences against error happening.
- These are called LATENT FAILURES.
- 3 bucket model
- SELF = Poor knowledge, fatigue, little experience/skill, feeling unwell
- CONTEXT = distraction, poor h andover, lack of team support, equipment
- TASK = errors, take complexity, new task, process

main purpose for each study type
A. Cross-sectional study - study of choice for prevalence
B. Case-control study - the study of choice for investigating RFs and the development of disease
C. Cohort study - study of choice for following exposure v non exposure over time
D. Randomized controlled trial - gold standard prospective study
E. Ecological study - observational and looks at population level findings
