Question 11

Describe a cohort study

Answer 11

*Participants are recruited to a study and followed up over time. Exposures and diseases are measured prospectively

Question 12

Describe a randomised control trial

Answer 12

*Participants are allocated by chance to different interventions and followed up and outcomes assessed.

*Considered the gold standard for effectiveness and efficacy when comparing one treatment to another

*Provide the strongest evidence on the effectiveness of treatments in clinical trials

Question 13

Describe a case report/series report

Answer 13

Description of the medical history of one or more patients

Question 14

Describe a cross sectional study

Answer 14

Observational study that analyses data collected from a population, or a representative subset, at a specific point in time

Question 15

Describe systematic review and meta analysis

Answer 15

All the evidence for RCTs looking at effectiveness of a particular treatment are synthesised

Question 16

Describe a case-control study

Answer 16

People with a disease are matched to those without it and earlier exposure to different factors are compared

Question 17

Describe what incidence is

Answer 17

*The number of new disease cases developing over a specific period of time in a defined population

*Incidence rate = number of new cases of a disease in a period/number of individuals in the population at risk

*Incidence estimates are obtained from longitudinal studies or derived from registers

Question 18

Describe what prevalence is

Answer 18

*The number of disease cases in a population at a given time

*prevalence = the number of affected individuals/total number of persons in a population

*prevalence estimates are obtained from cross-sectional studies or derived from registers that can relate to attributes or absence or presence of a disease

Question 19

What is the SIMD and what is it used for?

Answer 19

* Scotish Index of Multiple Deprivation which is an area based index which uses a range of data to decide which neighbourhoods are most deprived by ranking data zones in order of deprivation from 1 (most deprived) to 5/10 (least deprived)

Question 20

What are the seven factors of deprivation?

Answer 20

*Employment status

*Income

*Health and health care services

*Geographic access to services

*Crime

*Housing, living and working conditions

*Education, skills and training

Question 21

What are the three main type of study trials?

Answer 21

*Randomised control trial

*Cohort studies

*Case control studies

Question 22

What are convidence intervals?

Answer 22

*A confidence interval tells us the range of values that a true population treatment effect is likely to lie

*A CI that overlaps the value of no difference provides insufficient evidence

*A narrow CI is better as the larger the sample, the narrower the CI

Question 23

What are P values?

Answer 23

*Used in statistics to help determine the significance of the results

*P value less than 0.05 means you reject the null hypothesis and your results are statistically significant

Question 24

What is the highest level of evidence study?

Answer 24

Cochrane reviews which are systematic assessments of all the relevant RCTs which give the highest level of evidence

Question 25

What are the advantages of Cochrane reviews? (3)

Answer 25

*Randomisation reduces bias

*Gold standard for comparing the effectiveness of one treatment to another

*Control group comarability to no treatment

Question 26

How can you confirm if results are statistically significant with regards to confidence intervals and P values?

Answer 26

*When the confidence limit does not overlap 1 the results are statistically significant

*If the P value is less than 0.05 the results are statistically significant

Question 27

What is relative risk? (3)

Answer 27

*Relative risk is the ratio of incidence rate in exposed groups to incidence rates in non exposed groups

* It is the measurement of proportionate increase in disease rates in exposed groups

* It makes allowance for frequency of disease amongst people not exposed to supposed harmful agents

Question 28

Give four features of a randomised double blind control trial?

Answer 28

*Randomised double blind reducing bias of results which means the patients weren’t aware of the treatment they received and were randomly selected to a group

* Compares one treatement to a placebo or current treatment to investigate if there is any statistical significance to the results

* The randomisation of these studies facilitates statistical analysis

* follow up over two years which will give increased results for analysing

* Rely on a large number of volunteers
