Critical Appraisal of Research

 

 

Realtors rely on detailed property appraisals—conducted using appraisal tools—to assign market values to houses and other properties. These values are then presented to buyers and sellers to set prices and initiate offers.
Research appraisal is not that different. The critical appraisal process utilizes formal appraisal tools to assess the results of research to determine value to the context at hand. Evidence-based practitioners often present these findings to make the case for specific courses of action.

you will use an appraisal tool to conduct a critical appraisal of published research. You will then present the results of your efforts.

Guidance for Completing Your Appraisal

 

To ensure your presentation is thorough and professional, follow these steps when filling out your final table:

Level of Evidence: Assign a level of evidence (I-VI) based on a common hierarchy (e.g., Melnyk and Fineout-Overholt). RCTs are typically high (Level II), systematic reviews of RCTs are Level I (if included), and case reports are low (Level V or VI).

Bias/Threats: Identify specific threats to internal validity (e.g., confounding variables, blinding failure, sampling error) and external validity (e.g., non-representative sample).

Method Clarity: Focus on whether the study details are replicable. Were the tools (e.g., questionnaires) validated? Was the statistical plan sound?

Method Clarity: Focus on whether the study details are replicable. Were the tools (e.g., questionnaires) validated? Was the statistical plan sound?

Applicability: This is the critical step for evidence-based practice. Determine if the participants match your clinical population, if the outcomes are relevant to your practice goals, and if the intervention is feasible in your setting.
