Rapid Review
A rapid review is a form of systematic review that uses streamlined methods to produce evidence quickly and efficiently, often for time-sensitive decision-making in healthcare or policy.
Rapid reviews balance speed and rigor, trading some methodological depth for timely results.
Key Characteristics
- Shorter timelines (weeks to a few months)
- May restrict:
- Number of databases searched
- Language or publication date
- Study types included
- Often skips dual screening or full quality appraisal
- Transparent about methodological limitations
When to Use
- Public health emergencies (e.g., COVID-19)
- Clinical guidelines needing quick updates
- Health technology assessments (HTA)
- Policy or regulatory decisions
Limitations
- Higher risk of bias due to abbreviated methods
- May miss relevant studies or nuances
- Less reproducible than full systematic reviews

|---|---|---|---|
| Systematic Review | Months to >1 year | Very High | Definitive evidence synthesis |
| Rapid Review | 1–3 months | Moderate | Urgent decision-making |
| Scoping Review | Variable | Moderate | Exploratory mapping |
| Narrative Review | Flexible | Low to moderate | Broad expert-based overview |
