Critical Appraisal Systems for Scientific Evidence

Definition

Critical appraisal refers to the systematic evaluation of clinical research evidence to assess its validity, results, and relevance before applying it to decision-making in healthcare.


Joanna Briggs Institute (JBI) Critical Appraisal Tools

  • Purpose: Evaluate methodological quality across various study types (RCTs, cohort studies, case series, qualitative research, etc.).
  • Strengths: Detailed checklists tailored to each design; transparent criteria.
  • Limitations: Time-consuming; less commonly used in some medical specialties.

GRADE (Grading of Recommendations Assessment, Development and Evaluation)

  • Purpose: Rates certainty of evidence and strength of clinical recommendations.
  • Strengths: Widely endorsed by WHO, Cochrane, and others; integrates evidence with values/preferences.
  • Limitations: Complex for non-specialists; primarily designed for guideline development.

CASP (Critical Appraisal Skills Programme)

  • Purpose: Provides structured checklists for evaluating studies, especially qualitative and RCTs.
  • Strengths: Easy to use; ideal for teaching; widely adopted in nursing and public health.
  • Limitations: May oversimplify complex methodological issues.

AMSTAR (A MeaSurement Tool to Assess systematic Reviews)

  • Purpose: Assesses the quality of systematic reviews.
  • Strengths: Validated tool; helps distinguish high- from low-quality reviews.
  • Limitations: Not applicable to primary studies; requires familiarity with systematic review standards.

SIGN (Scottish Intercollegiate Guidelines Network) Checklists

  • Purpose: Appraise study quality for use in clinical guideline development.
  • Strengths: Emphasizes study design hierarchy and methodological rigor.
  • Limitations: More focused on clinical questions; less adaptable for broader research areas.
