Interrater Agreement in PRISMA: What You Need to Know

If you work in the field of systematic reviews, chances are you are familiar with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). PRISMA is a widely recognized guideline for reporting systematic reviews and meta-analyses, and it provides a comprehensive checklist of items to be included in a systematic review.

One important aspect of conducting a systematic review is ensuring interrater agreement among the review team. Interrater agreement refers to the degree of consensus among two or more raters (or reviewers) who are independently assessing the same set of data. In the context of PRISMA, interrater agreement is important because it ensures that all relevant information is captured in the review and reported accurately.

To achieve high interrater agreement in a PRISMA review, it is important to establish clear criteria for inclusion and exclusion of studies, as well as clear guidelines for data extraction and synthesis. The review team should also agree on a process for resolving disagreements that may arise during the review process.

In order to assess interrater agreement, a common measure used in systematic reviews is the kappa statistic. The kappa statistic measures the degree of agreement between two or more raters, and takes into account the degree of agreement that would be expected by chance alone. A kappa value of 1 indicates perfect agreement, while a value of 0 indicates no agreement beyond chance.

It is generally recommended that a kappa value of at least 0.70 be achieved in a systematic review to ensure high interrater agreement. However, some experts suggest that a higher value of 0.80 or even 0.90 may be necessary in some cases, depending on the complexity of the review and the importance of the information being assessed.

To conclude, achieving high interrater agreement in a PRISMA review is crucial for ensuring that all relevant information is captured and reported accurately. Establishing clear criteria for inclusion and exclusion, clear guidelines for data extraction and synthesis, and a process for resolving disagreements are all essential for achieving high interrater agreement. Finally, assessing interrater agreement through the kappa statistic is an important measure for validating the results of a systematic review.
