Modifications to the NEATS instrument for more appropriate and reproducible assessment of guidelines trustworthiness

Abstract

Rational

The National Guideline Clearinghouse Extent of Adherence to Trustworthy Standards (NEATS) instrument measures the adherence of clinical practice guidelines to the trustworthiness standards proposed by the Institute of Medicine. However, rather than trustworthiness or methodological quality, the NEATS instrument evaluates the quality of reporting in addressing the management of conflict of interest of guideline development group members, systematic review process and assessment of the certainty of the evidence, rating the strength of recommendations, and updating plans. Furthermore, the NEATS instrument instructions on rating items are sufficiently limited that they may compromise the reproducibility of the instrument.

Methods (Modifications to the NEATS Instrument)

In the context of a specific methodological research project, we developed modifications to the NEATS instrument that include modifying the wording of items to capture trustworthiness rather than reporting quality and creating an algorithm for all items that maps responses to a series of prompting questions and guides the user in arriving at a rating from 1 to 5 or yes, no, or unknown, as applicable.

Implications

Modifications to the NEATS instrument present a structured and practical framework to assess the degree to which clinical practice guidelines are trustworthy, and they ensure that items evaluate trustworthiness and improve the reproducibility of assessments across a range of raters' level of expertise in guideline methodology.
