Guideline for Systematic Reviews of Outcome Measurement Instruments
A 10-step procedure to help you prepare, select, evaluate, interpret and report on studies in your systematic review of patient-reported outcome measures (PROMs).
Systematic reviews of outcome measurement instruments are important tools for selecting the most suitable instrument to measure a construct of interest in a specific study population. High quality systematic reviews can provide a comprehensive overview of the quality (i.e. measurement properties) of instruments and supports evidence-based recommendations for the selection of the most suitable instrument for a given purpose (i.e. research or clinical practice; or discriminative, evaluative or predictive applications).
The COSMIN methodology is developed specifically for PROMs. It can also be used systematic reviews of other types of outcome measurement instruments, such as clinician-reported outcome measures and performance-based outcome measures, but it may need to be adapted for these purposes.
10-step procedure for conducting a systematic review
We developed a consecutive ten-step procedure for conducting a systematic review specifically for patient-reported outcome measures. Steps 1-4 concern preparing and performing the literature search, and selecting relevant studies. Steps 5-8 concern the evaluation of the quality of the eligible studies, the measurement properties, and the interpretability and feasibility aspects. Steps 9 and 10 concern formulating recommendations and reporting the systematic review.
To help you conducting a systematic review of PROMs, we developed several tools for you to use
A comprehensive user manual is written on how to conduct these ten steps in a systematic review of PROMs. In step 5 the content validity of an PROM is determined. As this is a very important and complex step to take, we wrote a separate user manual for assessing content validity of PROMs.
