Through and through th' inspir'd leaves,
Ye maggots, make your windings;
But O respect his lordship's taste,
And spare his golden bindings.

Relative Risks (RR) and Odds Ratios (OR)



Estimate of Relative Risks (RR) & Odds Ratios (OR) for Exposed & Unexposed Patients.

Relative risk = [a/(a+b)]/[c/(c+d)].

Odds ratio = (a/c)/(b/d).


Important Details:
  • Estimate of RR depends on having samples of exposed & unexposed patients, where the proportion of the patients with the outcome of interest can be determined.
  • The RR is not applicable to case-control studies in which the number of cases & controls, & hence proportion of people with the outcome, is chosen by the investigator.
  • For case-control studies a ratio of odds (OR) - the odds of a case patient being exposed divided by the odds of a control patient being exposed is used.
  • Using a simple 2x2 table, RRs & ORs can be represented as shown above.

GLIA (Guideline Implementability Appraisal) Tool For Assessing Guidelines

Elements of the GLIA (Guideline Implementability Appraisal) tool for assessing guidelines:
  • Decidability: precisely under what circumstances to do something
  • Executability: exactly what to do under the defined circumstances
  • Effect on process of care: the degree of impact of the recommendation on the usual workforce
  • Presentation and formatting: the degree to which the recommendation is recognizable and succinct
  • Measureable outcomes: the degree to which the guidelines identify markers or end-points for tracking the effect of implementation of the recommendation
  • Validity: the degree to which the recommendation reflects the intent of the developer and the strength of the evidence
  • Novelty and innovation: the degree to which the recommendation proposes behaviour considered unconventional by clinicians or patients
  • Flexibility: the degree to which the recommendation permits interpretation and allows for alternatives in its execution
  • Computability: the ease with which the recommendation can be operationalized in an electronic information system (only relevant if electronic implementation is planned).

Public Health 2.0 (Domain of Web 2.0)

"The scope of the Web today is hard to fathom. ... In fewer than 4000 days, we have encoded half a trillion versions of our collective story and put them in front of 1 billion people, or one-sixth of the world’s population. ... What we all failed to see was how much of this new world would be manufactured by users, not corporate interests." [1, from 2]

The rapidity of growth of the internet, and the amount of information produced by users for free, has been extraordinary. This freely distributed content and collaboration has been the powerful engine driving the second generation of Web services - Web 2.0.

There has also been a revolution in the use the internet for scientific research and dissemination of scientific knowledge. This is particularly noticeable in the area of Public Health.

This talk by Dr. Jennifer Gardy, who is co-leading the new genome research lab at the BC Centre for Disease Control (BCCDC, Canada), clearly shows the benefits of Public Health 2.0. She highlights the example of the recent pandemic of H1N1 Influenza A swine flu 2009. Dr Jennifer Gardy ends her talk by emphasizing how researchers & students should be willing to explore the benefits of Open Access publications, collaborative research, & emerging technologies.
