Study Notes
Defining Key Questions
- Key questions should be important, specific, and reflect an area of uncertainty in clinical knowledge or literature.
- A well-defined key question should provide the following information:
- Type of population being studied
- Type of exposure or intervention
- Comparator
- Outcomes that will be addressed
Framework for Key Questions: PICOTs
- PICOTs stands for Population, Intervention, Comparator, Outcomes, and Timing
- Population:
- Includes both nature of the condition being studied and underlying characteristics of the population (age, sex, etc.)
- Intervention:
- Drug
- Medical procedure
- Other healthcare intervention being assessed
- Must consider DDFI (dose, duration, frequency, intensity)
- Comparator:
- Placebo
- Active comparator
- Added to an existing treatment
- Must consider DDFI
- Outcomes:
- Endpoint measurements
- Clinical endpoints preferred over surrogate ones
- Timing:
- When the outcome will be measured
- How long the measurement will continue
- Setting:
- Provides information on how the healthcare was delivered (e.g., at clinic, teaching hospital, pharmacy, etc.)
Searching the Literature
- Review titles and abstracts to assess whether articles may be useful to the systematic review
- Review full-text articles to determine if they meet the eligibility criteria
- Hand search reference lists and grey literature
- Grey literature: any literature that isn’t published in journals (e.g., white papers, posters, clinicaltrials.gov, etc.)
