Abstract

OBJECTIVE:

Validate primary care diagnosis of gout by the Mexico and Netherlands classification criteria.

METHODS:

Questionnaires on gout characteristics was sent to all individuals aged ≥18 with ≥1 ICD-10 diagnosis of gout at 12 primary care centers.

RESULTS:

Positive predictive values for gout diagnosis ranged from 71% for the Netherlands criteria to 80% for the Mexico criteria. Maximum inflammation within 24 hours was the most common reported symptom (86%).

CONCLUSION:

The vast majority of gout cases in primary care fulfill classification criteria and are valid for research purposes.
