To evaluate the association between gout and fractures, focusing on the impact of medication adherence measured by the medication possession ratio (MPR).
Approach:
Data Sources: Utilized the National Health Insurance Service-National Health Screening Cohort (NHIS-HEALS) from 2002 to 2019, providing comprehensive longitudinal data.
Study Population: Included 4,107 newly diagnosed gout patients on allopurinol, matched with a control group of 12,321 non-gout individuals based on age, sex, and comorbidity.
Key Variables: Calculated MPR for allopurinol and assessed fracture incidence as a composite of vertebral, hip, and distal radius fractures.
Key Findings:
Gout incidence and prevalence have increased significantly in Korea over the last decade.
Conflicting evidence exists regarding the relationship between gout, serum uric acid levels, and fracture risk.
Medication adherence among gout patients is typically poor.
Interpretation:
The study aims to clarify the relationship between gout and fracture risk, particularly how adherence to urate-lowering therapy affects this association.
Limitations:
The study is observational and may be subject to confounding factors.
Data is limited to a specific population in South Korea, which may affect generalizability.
Conclusion:
The study seeks to provide insights into the fracture risk among gout patients and the role of medication adherence.
