Productivity and Medical Costs of Diabetes in a Large Employer Population

Abstract

OBJECTIVE -The purpose of this study was to assess the economic burden of diabetes from an employer's perspective. We analyzed the costs of diabetes, using claims data for an employed population and the prevalence of selected comorbid conditions. RESEARCH DESIGN AND METHODS -The data source is a claims database from a national Fortune 100 manufacturer. It includes medical, pharmacy, and disability claims for all beneficiaries (n Ͼ100,000). Both medical and work productivity costs of diabetes patients are compared by age with those of matched control subjects from the overall beneficiary population. Out-of-pocket and intangible costs are excluded.RESULTS -In 1998, the employer's mean annual per capita costs were higher for all diabetes beneficiaries than for control subjects ($7,778 Ϯ 16,176 vs. $3,367 Ϯ 8,783; P Ͻ 0.0001), yielding an incremental cost of $4,410 Ϯ 18,407 associated with diabetes. The medical and productivity costs for employees with diabetes were significantly (P Ͻ 0.0008) higher than for control subjects. The incremental cost of diabetes among employees ranged from $4,671 (aged 18 -35 years) to $4,369 (aged 56 -64 years).CONCLUSIONS -Diabetes imposes a significant economic burden on employers, particularly when including productivity costs. Employers should select health plans that provide enriched benefits to diabetes patients, including ready access to medical and pharmacy services as well as aggressive diabetes management programs.

The cost burden of diabetes mellitus: the evidence from Germany—the CoDiM Study

“…Until now, few cost-of-diabetes studies have stratified per-patient costs according to age [1,9,22,23] and type of therapy [4,23,24]. Indeed, these characteristics have typically been assessed by univariate analysis.…”

Examining the economic costs related to lifestyle and pharmacological interventions in youth with Type 2 diabetes

“…One illustration of this phenomenon is the finding that diabetes patients consume a disproportionately high percentage of all medical expenditures [2]. Per capita, healthcare expenditures for patients with diabetes are two-to five-times that of similar patients without diabetes [3][4][5][6].…”

Capsule Commentary on Bishu et al., Quantifying the Incremental and Aggregate Cost of Missed Workdays in Adults with Diabetes

“…For example, Ramsey et al 3 estimated the costs associated with work loss due to diabetes using 1998 administrative claims data where work loss costs were determined based on productivity costs and measured by "medically related absences"; this is more accurate than just using missed workdays. Because claims data provide information on actual dates of medical care and disability, including only missed workdays, this likely reflects a more accurate measure of productivity costs due to diabetes.…”
