2016 Fibromyalgia Diagnostic Criteria: Clinical Guide

Overview

Assesses the 2016 fibromyalgia criteria using widespread pain, symptom severity and generalised pain.

Clinical Significance

Criteria are met when generalised pain is present in at least 4 of 5 regions, symptoms persist for at least 3 months, and the WPI/SSS combination reaches the specified threshold.

When to Use

• Use as structured clinical decision support when the required data are available and reliable.

How It Is Calculated

• The displayed variables are combined using the published equation or weighted point system.

Interpretation

• Criteria are met when generalised pain is present in at least 4 of 5 regions, symptoms persist for at least 3 months, and the WPI/SSS combination reaches the specified threshold.

Worked Example

Enter verified patient data in the displayed units; MedicalC applies the published equation or point system.

Limitations

• Classification and prognostic tools can be misapplied outside their validated population.
• Missing, estimated or non-contemporaneous data may materially change the result.

Clinical Pearls

• Document the input values, units, date and clinical setting with the result.
• Use serial scores only when the same instrument and measurement method are used consistently.

Common Mistakes

• Using the tool without confirming entry criteria.
• Selecting overlapping findings that should be represented by the highest-scoring item only.
• Treating a classification threshold as a standalone diagnosis.
