Insights
Employees with gout have a higher prevalence of metabolic syndrome and related conditions, leading to increased annual medical services (AMS) costs. This highlights the need for proactive management and treatment of gout and its comorbidities.
Area of Science:
- Medical Research
- Epidemiology
- Health Economics
Background:
- Gout is a metabolic disorder associated with various comorbidities.
- Understanding the economic burden of gout-related conditions is crucial for healthcare management.
Purpose of the Study:
- To compare the prevalence of metabolic syndrome-associated disorders in employees with and without gout.
- To evaluate the differences in annual medical services (AMS) costs for treating these conditions.
Main Methods:
- A cohort study comparing employees with gout (identified via ICD-9 codes) to matched controls without gout.
- Propensity-score matching and t-tests were used to analyze prevalence and AMS data from the Human Capital Management Services Research Reference Database.
- Disorders were categorized using Agency for Healthcare and Research Quality (AHRQ) diagnostic categories.
Main Results:
- Employees with gout showed significantly higher prevalence ratios (approx. 2:1) for conditions like essential hypertension, hyperlipidemia, and diabetes mellitus without complications compared to controls (p < 0.05).
- These gout patients also incurred higher mean annual medical services (AMS) for these conditions (p < 0.0001).
- Study limitations included a small sample size, retrospective design, and potential for miscoding.
Conclusions:
- Individuals with gout face an elevated risk of metabolic syndrome and associated comorbidities.
- Awareness and proactive management by patients and clinicians are essential for prevention and treatment.
- The findings underscore the importance of addressing gout and its related health issues to mitigate long-term morbidity and healthcare costs.
Objective:
A cohort of employees with gout were compared to those without to evaluate the differences in prevalence of disorders associated with metabolic syndrome (both those considered underlying and those associated with end-stage morbidity and mortality) as well as the cost of annual medical services (AMS) required for treatment of these conditions.
Methods:
Employees with gout were identified by International Classification of Diseases-9 (ICD-9) code during the calendar years of 2001-2004 and compared to propensity-score matched employees without gout using the Human Capital Management Services Research Reference Database. T-tests were then used to compare prevalence and average AMS of comorbid disorders defined from Agency for Healthcare and Research Quality (AHRQ) diagnostic categories.
Results:
'Hyperlipidemia', 'essential hypertension', and 'diabetes mellitus without complications' ranked in the top 10 categories of mean number of AMS for employees with gout using AHRQ specific categories; the values were higher than found for those without gout (all p < 0.0001). 'Essential hypertension', 'hyperlipidemia', 'diabetes mellitus without complications', and 'coronary atherosclerosis' showed an approximate 2:1 prevalence ratio for employees with gout over those without (p < or = 0.05). Main study limitations include the small number of subjects with gout, retrospective study design, and possible miscoding and/or non-coding of individuals with the studied disorders.
Conclusion:
These results support the continued need for patients with gout and their clinicians to be aware of the possibility of the increased risk of associated metabolic syndrome and related comorbidities in these individuals, emphasizing the need for prevention when possible and treatment when necessary.
