Abstract
PURPOSE Anchor institutions ("anchors") are large employers, rooted in a community by reason of mission, capital, or relationships. Many anchors have encouraged coronavirus vaccination for employees and their families. Our objective was to determine whether the presence of an anchor was associated with a higher county-level vaccination rate. METHODS A cross-sectional study focused on 745 small- and mid-sized US counties. We used data from the Centers for Disease Control and Prevention, Reference USA's US Business Database, Economic Innovation Group's Distressed Communities Index database, 2021 County Health Ratings and Rankings, 2020 US Presidential Election popular vote data, and National Center for Health Statistics urban-rural classification data. We constructed 3 explanatory variables of interest: a binary variable indicating whether the county had an anchor; a continuous variable representing the number of anchors within a county; and the percent of all workers in the county who were employed by an anchor. Multivariable linear regression models were adjusted for race/ethnicity, political party allegiance, rurality, economic distress, and prevalence of smoking and adult obesity. FINDINGS Counties with an anchor had vaccination rates 2.31 (P<.01) percentage points higher than those without an anchor. The number of anchors in a county was also significantly associated with higher vaccination rates. CONCLUSIONS Efforts by anchors to encourage vaccination may have been successful, and that anchors may be well positioned to amplify public health messages. However, the influence and efforts of anchors to increase vaccination did not fully mitigate disparities in vaccination rates by race, ethnicity, and political party allegiance.

Abstract
OBJECTIVE To estimate productivity losses and costs and medical costs due to type 2 diabetes (T2D) among employees aged 18-64 years. RESEARCH DESIGN AND METHODS Using 2018-2019 MarketScan databases, we identified employees with T2D or no diabetes among those with records on workplace absences, short-term disability (STD), and long-term disability (LTD). We estimated per capita mean annual time loss attributable to T2D and its associated costs, calculated by multiplying time loss by average hourly wage. We estimated direct medical costs of T2D in total and by service type (inpatient, outpatient, and prescription drugs). We used two-part models (productivity losses and costs and inpatient and drug costs) and generalized linear models (total and outpatient costs) for overall and subgroup analyses by age and sex. All costs were in 2019 U.S. dollars. RESULTS Employees with T2D had 4.2 excess days lost (20.8 vs. 20.3 absences, 6.4 vs. 3.3 STD days, and 1.0 vs. 0.4 LTD days) than those without diabetes. Productivity costs were 13.3% ($680) higher and medical costs were double (total $11,354 vs. $5,101; outpatient $4,558 vs. $2,687, inpatient $3,085 vs. $1,349, prescription drugs $4,182 vs. $1,189) for employees with T2D. Employees aged 18-34 years had higher STD days and outpatient costs. Women had more absences and STD days and higher outpatient costs than men. CONCLUSIONS T2D contributes nearly $7,000 higher annual per capita costs, mostly due to excess medical costs. Our estimates may assist employers to assess potential financial gains from efforts to help workers prevent or better manage T2D.

Abstract
Sugar-sweetened beverages (SSBs) increase chronic disease risk. We estimated the impact on employee health and health care spending of banning SSB sales in California-based health care organizations. We used survey data from a large, multisite health care organization in California, sampling 2,276 employees three months before and twelve months after a workplace SSB sales ban was imposed. We incorporated the survey data into a simulation model to estimate chronic disease incidence and costs. We estimated that an SSB ban as effective as the one observed would save about $300,000 per 10,000 people over ten years among similar employers, as a result of averted health care and productivity spending—after both SSB sales losses and non-SSB beverage sales gains were accounted for. Sales bans would typically need to reduce SSB consumption by 2.2 ounces per person per day for lost revenue to be fully offset if there were no increase in non-SSB beverage sales.

Abstract
Diabetes is a costly chronic condition in the United States. The incremental increase in costs of the disease can begin and accelerate prior to first diagnosis. This study conducts a retrospective analysis of claims data from Truven Health MarketScan® Commercial Claims Database to track per capita annual medical expenditures among a single panel of commercially insured patients for 5 years preceding a new diabetes diagnosis. Case subjects, defined as individuals newly diagnosed with diabetes in 2014, are compared to control subjects, defined as individuals who do not have a diabetes diagnosis. Arithmetic means, compound annual growth rates, and propensity score matching models are used to track the differential in expenditures across health care sectors. This analysis finds that the incremental rise in costs of diabetes are shown to begin at least 5 years before diagnosis of the disease and accelerate immediately after diagnosis. Results of the matching model suggest that the newly diagnosed case subjects spent $8941 more than control subjects not diagnosed with diabetes over the span of 5 years, with approximately $4828 in the year of diagnosis. The compounded annual growth rate in per capita annual medical expenditures between 2010–2014 was almost 9% higher among case subjects at 14.3% in the matched models. Results show that the rise in medical spending associated with diabetes begins well in advance of the first diabetes diagnosis and support the need to encourage physicians to implement timely identification and prevention efforts to reduce the economic burden of the disease.

Abstract
ObjectiveTo evaluate how clinically measured glucose metabolism categories predict registered participation in working life.MethodsIn the 46-year follow-up of Northern Finland Birth Cohort 1966 (n=5328, 2342 men and 2986 women), we used oral glucose tolerance tests, surveys and glycated haemoglobin to determine glucose metabolism categorised as normal, pre-diabetes, screen-detected and previous type 2 diabetes (T2D). Consequent participation in working life during the 2-year follow-up period was measured as registered disability, unemployment and employment days, for which incidence rate ratios (IRRs) with 95% CIs were calculated using Poisson regression, adjusted for baseline employment and socioeconomic, health-related and behavioural factors.ResultsIn comparison to normal glucose, all categories of impaired glucose metabolism were associated with poorer participation in working life in the unadjusted models. After adjustments, the risks (IRR (95% CI)) of disability days remained heightened by both screen-detected and previous T2D among men (1.3 (1.3 to 1.4) and 1.5 (1.4 to 1.5), respectively), whereas among women the risks were lowered (0.9 (0.8 to 0.9) and 0.9 (0.9 to 1.0), respectively). The risks of unemployment were consistently higher in all categories of impaired glucose metabolism, and were the highest among women with previous T2D (1.6 (1.5 to 1.6)). Correspondingly, the rates of total employment days were lower in relation to screen-detected T2D among men and women (5% and 6%, respectively), and previous T2D (6% and 3%).ConclusionsOverall, impaired glucose metabolism associated with deteriorated working life participation already in middle age. The high prevalence of impaired glucose metabolism emphasises the need for actions to support sustainable working careers.

Abstract
OBJECTIVE To evaluate the effectiveness of interventions aimed at the prevention of risk factors and incidence of type 2 diabetes in the workers population. METHODS Systematic review of interventions aimed at adult workers at risk of type 2 diabetes published in Medline, Embase, Web of Science, Central Cochrane Registry of Controlled Trials, and Lilacs. Randomized trials, quasi-experimental research and cohort studies were selected; in English, Spanish and Portuguese; published from 2000 to 2017. Intervention effectiveness was evaluated concerning the incidence of type 2 diabetes and a significant reduction in body weight, or another anthropometric or metabolic parameter. RESULTS 3,024 articles were generated, of which 2,825 that did not answer the research question were eliminated, as well as 130 that did not evaluate original interventions, 57 carried out outside the workplace and two reviews; so that 10 selected items remained. Interventions based on structured programs previously evaluated and integrated into the workplace had a favorable impact on the reduction of body weight and other risk factors. CONCLUSIONS The effectiveness of lifestyle interventions for the prevention of type 2 diabetes should be based on structured programs with proven effectiveness and adapted to the workplace, with employer participation in the provision of schedules and work environments.

Abstract
OBJECTIVE We assessed the relationship between diabetes mellitus (DM) and measures of worker productivity, direct health care costs, and costs associated with lost productivity (LP) among health care industry workers across two integrated health care systems. METHODS We used data from the Value Based Benefit Design Health and Wellness Study Phase II (VBD), a prospective study of employees surveyed across health systems. Survey and health care utilization data were linked to estimate LP and health care utilization costs. RESULTS Mean marginal lost productive time per week was 0.56 hours higher for respondents with DM. Mean adjusted monthly total health care utilization costs were $467 higher for respondents with DM. CONCLUSION The impact of DM is reflected in higher rates of LP and higher indirect costs for employers related to LP and higher health care resource use.

Abstract
BACKGROUND Limited data exist on real-world treatment patterns for diabetic macular edema (DME) in Korea. In this study, we investigated DME treatment patterns from 2009 to 2014 and the impact of baseline treatment on healthcare resource utilization and visual acuity (VA) outcomes. METHODS A retrospective cohort chart review of DME patients treated at 11 hospital ophthalmology clinics between January 1, 2012 and December 31, 2013 was conducted. We collected data on demographics, healthcare resource utilization (clinic visits, treatment visits, and visits for ocular investigations), distribution of DME treatments, and VA. RESULTS Overall, 522 DME patients (men, 55.2%; mean age, 59 years; mean HbA1c [n = 209], 8.4%) with 842 DME eyes were evaluated. For all treatments, healthcare resource utilization was significantly higher during the first 6 months versus months 7-12, year 2, or year 3 (P ≤ 0.001), but was highest for patients whose first treatment was an anti-vascular endothelial growth factor (VEGF) treatment (visits/quarter; anti-VEGF, 1.9; corticosteroids, 1.7; laser, 1.4). Use of macular laser therapy decreased (44% to 8%), whereas use of anti-VEGF injections increased (44% to 69%) during the study period. However, VA improvement was not commensurate with healthcare resource utilization of anti-VEGF treatment (mean VA gain, 2.7 letters). CONCLUSION A trend toward increasing use of intravitreal anti-VEGF injections for DME treatment was observed in Korea. However, the frequency of dosing and monitoring was lower in clinical practice versus major clinical trials, which may have led to the less-than-favorable improvements in visual outcomes.

Abstract
AIM This study aims to examine the humanistic and economic burden of cardiovascular disease (CVD)-related comorbidities and hypoglycaemia among respondents with type 2 diabetes (T2D) in Japan. METHODS This study used the Japan National Health and Wellness Survey 2016 database. Respondents who self-reported a physician-diagnosed T2D were included. Respondents with or without the condition of interest (CVD-related comorbidities or hypoglycaemia) were compared via generalized linear models in terms of the outcome variables: (1) health-related quality of life (HRQoL), (2) work productivity and activity impairment, (3) healthcare resource utilization and (4) economic costs. RESULTS A total of 1478 survey respondents reported a diagnosis of T2D (mean age 63.6 ± 10.6 years, mean HbA1c 6.91 ± 1.1%). Of whom, 804 subjects (54.4%) had at least one CVD related comorbidities, and 369 subjects (29.3%) reported experiences of hypoglycaemia episodes. Patients with CVD-related comorbidities or hypoglycaemia episodes had worse HRQoL, more work and activity impairment, increased health care visits, and higher costs. CONCLUSIONS CVD related comorbidities and hypoglycaemia remains a significant humanistic and economic burden in patients with T2D. The findings suggested that appropriate T2D management with proper medication choice are important to control CVD related comorbidities and hypoglycaemia among T2D patients to alleviate the burden.

Abstract
AbstractDiabetes is a metabolic syndrome increasing rapidly due to occupational stress, lack of physical activity, sedentary lifestyle and increasing occurrence of obesity, associated with rapidly growing urbanization and industrialization. Due to erroneous carbohydrate metabolism, diabetics are more prone to chronic complications like nephropathy, neuropathy, retinopathy, coronary artery disease and peripheral arterial disease resulting in tissue damage. Current treatment protocols to these problems produce more serious adverse effects and are costly too. Medicinal plants provide an alternative of safe, reliable and cost-effective pharmacological source to all these ailments. This review provides the compiled data of isolated active phytoconstituents of 22 potent antidiabetic plants with their plant-part used, which might be useful for drug development.

Abstract
The United States has 86 million adults with prediabetes. Individuals with prediabetes can prevent or delay the development of type 2 diabetes through lifestyle modifications such as participation in the National Diabetes Prevention Program (DPP), thereby mitigating the medical and economic burdens associated with diabetes. A cohort analysis of a commercially insured population was conducted using individual-level claims data from Truven Health MarketScan® Lab Database to identify adults with prediabetes, track whether they develop diabetes, and compare medical expenditures for those who are newly diagnosed with diabetes to those who are not. This study then illustrates how reducing the risk of developing diabetes by participation in an evidence-based lifestyle change program could yield both positive net savings on medical care expenditures and return on investment (ROI). Annual expenditures are found to be nearly one third higher for those who develop diabetes in subsequent years relative to those who do not transition from prediabetes to diabetes, with an average difference of $2671 per year. At that cost differential, the 3-year ROI for a National DPP is estimated to be as high as 42%. The results show the importance and economic benefits of participation in lifestyle intervention programs to prevent or delay the onset of type 2 diabetes.

Abstract
PURPOSE OF REVIEW This study aims to summarize the recent peer-reviewed literature on workplace interventions for prevention of type 2 diabetes mellitus (T2DM), including studies that translate the Diabetes Prevention Program (DPP) curriculum to workplace settings (n = 10) and those that use different intervention approaches to achieve the specific objective of T2DM prevention among employees (n = 3). RECENT FINDINGS Weight reduction was achieved through workplace interventions to prevent T2DM, though such interventions varied substantially in their effectiveness. The greatest weight loss was reported among intensive lifestyle interventions (i.e., at least 4 months in duration) that implemented the structured DPP curriculum (n = 3). Weight reduction was minimal among less intensive interventions, including those that substantially modified the DPP curriculum (n = 2) and those that used non-DPP intervention approaches to prevent T2DM (n = 3). Most studies (n = 12) reported increased levels of physical activity following the intervention. Implementation of the DPP in workplaces may be an effective strategy to prevent T2DM among employees.

Abstract
PURPOSE To examine the comorbidity profile and update estimates of health care resource utilization for commercially insured, working-age adults with diabetic macular edema (DME) relative to a matched comparison group of diabetic adults without DME. Additional comparisons were made in the subgroup of pseudophakic patients. PATIENTS AND METHODS A retrospective matched-cohort study of commercially insured diabetic adults aged 18-63 years was conducted using medical and outpatient pharmacy claims (July 1, 2008-June 30, 2013). Outcomes included diabetes-related and ocular comorbidities and health care resource utilization (any health care visit days, outpatient visit days, inpatient visit days, emergency room visits, eye care-related visit days, unique medications) in the 12-month post-index period. RESULTS All diabetes-related and ocular comorbidities were significantly more prevalent in DME cases versus non-DME controls (P<0.05). A significantly greater proportion of DME cases utilized eye care-related visits compared with non-DME controls (P<0.001). DME cases had almost twice the mean number of total health care visit days compared to non-DME controls (28.6 vs 16.9 days, P<0.001), with a minority of visit days being eye care-related (mean 5.1 vs 1.5 days, P<0.001). Similar trends were observed in pseudophakic cohorts. CONCLUSION This working-age DME population experienced a mean of 29 health care visit days per year. Eye care-related visit days were a minority of the overall visit burden (mean 5 days) emphasizing the trade-offs DME patients face between managing DME and their overall diabetic disease. Insights into the complex comorbidity profile and health care needs of diabetic patients with DME will better inform treatment decisions and help optimize disease management.

Abstract
OBJECTIVE To examine the impact of type 2 diabetes on direct and indirect costs and to describe the effect of relevant diabetes-related factors, such as type of treatment or glycaemic control on direct costs. DESIGN Bottom-up excess cost analysis from a societal perspective based on population-based survey data. PARTICIPANTS 9160 observations from 6803 individuals aged 31-96 years (9.6% with type 2 diabetes) from the population-based KORA (Cooperative Health Research in the Region of Augsburg) studies in Southern Germany. OUTCOME MEASURES Healthcare usage, productivity losses, and resulting direct and indirect costs. METHODS Information on diabetes status, biomedical/sociodemographic variables, medical history and on healthcare usage and productivity losses was assessed in standardised interviews and examinations. Healthcare usage and productivity losses were costed with reference to unit prices and excess costs of type 2 diabetes were calculated using generalised linear models. RESULTS Individuals with type 2 diabetes had 1.81 (95% CI 1.56 to 2.11) times higher direct (€3352 vs €1849) and 2.07 (1.51 to 2.84) times higher indirect (€4103 vs €1981) annual costs than those without diabetes. Cardiovascular complications, a long diabetes duration and treatment with insulin were significantly associated with increased direct costs; however, glycaemic control was only weakly insignificantly associated with costs. CONCLUSIONS This study illustrates the substantial direct and indirect societal cost burden of type 2 diabetes in Germany. Strong effort is needed to optimise care to avoid progression of the disease and costly complications.

Abstract
BACKGROUND AND OBJECTIVE Diabetic macular edema (DME) is a leading cause of blindness for non-elderly adults; however, health care-associated burden data from this population is lacking. The authors describe health care-associated burden in non-elderly patients with DME compared to those with diabetes and no DME. PATIENTS AND METHODS In this retrospective, large-cohort study examines enrollment and health care claims (2007 to 2011) from a national database of insured patients aged 18 to 63 years (mean: 51). Comorbidity and health care utilization differences between patients with DME (n = 24,326) and matched controls with diabetes but no DME (n = 122,710) were analyzed over 1 and 3 years. RESULTS DME patients had significantly more baseline comorbidities, and generally developed them at a higher rate over the study. Health care resource utilization rates were significantly higher in DME patients for every category analyzed. Patients with DME averaged more than 10 health care visits more than those with diabetes but no DME (25.5 vs 14.9; P < .001). CONCLUSION Working-age patients with DME exhibit a complicated comorbidity profile and high associated burden of health care consumption. Considering this burden is critical for managing this complex population.

Abstract
Using data from four waves of the National Health and Nutrition Examination Survey, we examine the difference between individuals with diagnosed and undiagnosed cases of type 2 diabetes and their labor supply decisions. We show that a diagnosis of type 2 diabetes is significantly associated with a reduction in both male and female employment probability by 11 and 19 percentage points, respectively. Additionally, hours worked by individuals with diagnosed type 2 diabetes are 7h lower per week for males and 8h lower per week for females. Further, individuals with undiagnosed type 2 diabetes experience a drop in labor supply somewhat smaller but similar to their diagnosed counterparts. This association may be driven by the similarities between undiagnosed and very recently diagnosed type 2 diabetes. In all estimations, we consistently find that type 1 diabetes has a different effect than either diagnosed or undiagnosed type 2 diabetes.

Abstract
BACKGROUND There has been a widely documented and recognized increase in diabetes prevalence, not only in high-income countries (HICs) but also in low- and middle-income countries (LMICs), over recent decades. The economic burden associated with diabetes, especially in LMICs, is less clear. OBJECTIVE We provide a systematic review of the global evidence on the costs of type 2 diabetes. Our review seeks to update and considerably expand the previous major review of the costs of diabetes by capturing the evidence on overall, direct and indirect costs of type 2 diabetes worldwide that has been published since 2001. In addition, we include a body of economic evidence that has hitherto been distinct from the cost-of-illness (COI) work, i.e. studies on the labour market impact of diabetes. METHODS We searched PubMed, EMBASE, EconLit and IBSS (without language restrictions) for studies assessing the economic burden of type 2 diabetes published from January 2001 to October 2014. Costs reported in the included studies were converted to international dollars ($) adjusted for 2011 values. Alongside the narrative synthesis and methodological review of the studies, we conduct an exploratory linear regression analysis, examining the factors behind the considerable heterogeneity in existing cost estimates between and within countries. RESULTS We identified 86 COI and 23 labour market studies. COI studies varied considerably both in methods and in cost estimates, with most studies not using a control group, though the use of either regression analysis or matching has increased. Direct costs were generally found to be higher than indirect costs. Direct costs ranged from $242 for a study on out-of-pocket expenditures in Mexico to $11,917 for a study on the cost of diabetes in the USA, while indirect costs ranged from $45 for Pakistan to $16,914 for the Bahamas. In LMICs-in stark contrast to HICs-a substantial part of the cost burden was attributed to patients via out-of-pocket treatment costs. Our regression analysis revealed that direct diabetes costs are closely and positively associated with a country's gross domestic product (GDP) per capita, and that the USA stood out as having particularly high costs, even after controlling for GDP per capita. Studies on the labour market impact of diabetes were almost exclusively confined to HICs and found strong adverse effects, particularly for male employment chances. Many of these studies also took into account the possible endogeneity of diabetes, which was not the case for COI studies. CONCLUSIONS The reviewed studies indicate a large economic burden of diabetes, most directly affecting patients in LMICs. The magnitude of the cost estimates differs considerably between and within countries, calling for the contextualization of the study results. Scope remains large for adding to the evidence base on labour market effects of diabetes in LMICs. Further, there is a need for future COI studies to incorporate more advanced statistical methods in their analysis to account for possible biases in the estimated costs.

Abstract
The economic burden of diabetes and the effects of the disease on the labor force are of substantial importance to policy makers. We examined the impact of diabetes on leaving the labor force across sixteen countries, using data about 66,542 participants in the Survey of Health, Ageing and Retirement in Europe; the US Health and Retirement Survey; or the English Longitudinal Study of Ageing. After matching people with diabetes to those without the disease in terms of age, sex, and years of education, we used Cox proportional hazards analyses to estimate the effect of diabetes on time of leaving the labor force. Across the sixteen countries, people diagnosed with diabetes had a 30 percent increase in the rate of labor-force exit, compared to people without the disease. The costs associated with earlier labor-force exit are likely to be substantial. These findings further support the value of greater public- and private-sector investment in preventing and managing diabetes.

Abstract
AIMS To contribute to the research on diabetes and social inequality by presenting national data on incident diabetes mellitus, stratified according to socio-economic status. METHODS National registers were combined, linking socio-economic status with incident diabetes over a 10-year period (2001-2010). The study population comprised employees in Denmark aged 20-59 years at baseline. Poisson regression analysis was used to estimate socio-economic rate ratios. Excess fraction analysis was used to determine the proportion of cases that would not have occurred if morbidity rates in each socio-economic group had been as low as those in the reference group. Monte Carlo simulation was used to calculate 95% CIs for excess fraction estimates RESULTS A total of 1 005 572 men and 951 039 women were included in the analysis. The follow-up yielded 43 439 cases in 9 533 199 person-years at risk among men and 29 266 cases in 9 163 405 person-years at risk among women. Using 'professionals' as a reference group, higher levels of relative risk were observed among every other socio-occupational group. The excess fraction was, 0.342 (95% CI 0.329-0.354) among men and 0.359 (95% CI 0.349-0.369) among women. CONCLUSIONS Excess fraction analysis suggests that more than a third of cases of diabetes could be prevented if all employees were exposed to the same working conditions as the reference population. Acknowledging potential confounders, the observed levels of incident diabetes among the workforce highlight the potential gains to be had by better use of the workplace as an arena for prevention. Greater integration of occupational health and general healthcare is required to achieve this.

Abstract
Objectives The rise in prevalence of diabetes is alarming and research ascribes most of the increase to lifestyle. However, little knowledge exists about the influence of occupational factors on the risk for developing diabetes. This study estimates the importance of work and lifestyle as risk factors for developing diabetes mellitus among healthcare workers and explores the association of work factors and obesity, which is a risk factor for diabetes. Methods Questionnaire-based prospective cohort study among 7,305 health care workers followed for seven years in the Danish National Diabetes Register. We used bivariate comparisons to give an unadjusted estimate of associations, followed by adjusted survival analysis and logistic regression models to estimate the influences of potential risk factors related to job, health and lifestyle on diabetes and obesity. Results During seven years of follow up, 3.5% of participants developed diabetes, associated with obesity (HR = 6.53; 95% CI 4.68–9.10), overweight (HR = 2.89; CI 2.11–3.96) age 50–69 y (HR = 2.27; 95% CI 1.57–3.43) and high quality of leadership (HR = 1.60; CI 1.19–2.16). Obesity at baseline was most common among the youngest employees, and was mainly associated with developing diabetes (OR = 3.84; CI 2.85–5.17), impaired physical capacity and physical inactivity. In the occupational setting, obesity was associated with shift work, severe musculoskeletal pain, low influence, but also by good management, fewer role conflicts and a positive work-life balance. Looking only at non-smokers, removed the influence of age and pain. However, non-smokers also had higher depression scores and more role conflicts. Conclusions Confirming obesity as the strongest risk factor for developing diabetes, the present study identified few occupational risk factors. However, obesity, the key risk factor for diabetes, had a more variable relation with work than did diabetes.

Abstract
Background To evaluate the cost of diabetes related micro- and macrovascular complications in Iranian people with type 2 diabetes mellitus. Methods In routine clinical practice, people with type 2 diabetes mellitus were assessed for 10 years at a diabetes care center. The type of medications and clinical data were extracted from patients’ documents. Mortality rate and the incidence of micro- and macrovascular complications recorded in patients’ documents were analyzed. Cost analysis was comprised of 1) para clinic costs as well as laboratory, medications, clinical visits and nonmedical costs 2) inpatient costs as well as hospital admission costs, disability, and mortality costs. Results From 1562 people with type 2 diabetes mellitus, a total of 1000 patients with mean duration disease of 11.2 years, who had completed information in their documents, were studied. All people were free from complications at baseline. Mean cumulative incidence of diabetes-related complications over 10 years were 10.9 ± 3.5%, 8.0 ± 3.1%, 4.6 ± 1.7%, 9.1 ± 3.6% and 2.3 ± 0.9% for peripheral neuropathy and diabetic foot ulcer, nephropathy, ophthalmic complications, cardiovascular disease and death, respectively. People with better glycemic control had less complication and also related expenditures. Average para clinic cost per patient was 393.6 ± 47.8 and average inpatient cost per patient was 1520.7 ± 104.5 USD. Conclusions Our findings demonstrate considerable incidence of diabetes chronic complications and also high health care expenditure for related complications among our patients. As the number of people with diabetes continues to rise, early detection of the disease and implementation of timely and appropriate therapeutic strategies could decrease the burden of diabetes chronic complications and also huge related expenditures.

Abstract
The best treatment option for children with Type 2 diabetes has not yet been established. The Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study is currently testing the efficacy of three therapies: metformin, metformin plus rosiglitazone and metformin plus an intensive lifestyle intervention. The relative cost-effectiveness of these therapies is also being examined. This review discusses the rationale for the design and methods applied in the economic analysis. The design of the economic analysis in the TODAY study was influenced by the existing literature and two primary study parameters: the nature of the interventions and the participants' age. The lifestyle intervention is an intensive behavioral intervention comprising diet and physical activity. Since economic factors influence both diet and physical activity, the analytical plan includes measurement of food and exercise-related purchases. Due to the young age of the participants, the impact of the intervention on adult caregivers is also included in the analysis. This analysis focuses on the time spent by the caregivers in both medical treatment and nutrition- and activity-related activities, and the value of this time relative to usual activities. Important methodological questions include how and when to collect information, not only on medical costs, but also on the impact of caregiver time, travel, food and equipment purchases. In the TODAY study, these latter resources are being measured by regularly administered surveys completed by the caregivers. The approach to the cost-effectiveness assessment undertaken by the TODAY study is one of the first in diabetes research to focus on youth and to include a societal perspective, regular and prospective assessment of clinician and caregiver time, and a comprehensive assessment of the costs associated with lifestyle behaviors. It can serve as a model for future studies of diabetes treatments.

Abstract
Using data from the National Longitudinal Survey of Youth 1979, the current study examines the effect of type I and type II diabetes on employment status and wages. The results suggest that both the probability of employment and wages are negatively related to the number of years since the initial diagnosis of diabetes. Moreover, the effect of diabetes duration on the probability of employment appears to be nonlinear, peaking around 16 years for females and 10 years for males. A similar negative effect on wages is found only in male diabetics. Finally, the results suggest that failure to distinguish between type I and type II diabetics may lead to some counterintuitive results.

Abstract
This study evaluated the relationships between compliance with oral hypoglycemic agents and health care/short-term disability costs in a large manufacturing company. The retrospective analysis used an observational cohort drawn from active employees of Ford Motor Company. The study population consisted of 4978 individuals who were continuously eligible for 3 years (between 2001-2007) and who received a prescription for an oral hypoglycemic agent during that time. Medical, pharmacy, and short-term disability claims data were obtained from the University of Michigan Health Management Research Center data warehouse. Pharmacy claims/refill data were used to calculate the proportion of days covered (PDC); an individual was classified as compliant if his/her PDC was ≥80%. Model covariates included age, sex, work type, and Charlson comorbidity scores. The impact of compliance on disability and health care costs was measured by comparing the costs of the compliant with those of the noncompliant during a 1-year follow-up. Among these employees, compliant patients had lower medical, higher pharmacy, and lower short-term disability costs than did the noncompliant. After adjusting for demographics and comorbidity, noncompliance was associated with statistically higher short-term disability costs ($1840 vs. $1161, P<0.0001), longer short-term disability duration, and an increase in short-term disability incidence (21.5% of the noncompliant had a claim compared to 16.0% of the compliant, P<0.0001). These results suggest that medication compliance may be important in curtailing the rise of health care/disability costs in the workplace. Employers concerned with the total costs associated with diabetes should not overlook the impact of compliance on short-term disability.

Abstract
BACKGROUND Allergic rhinitis (AR) is a highly prevalent allergic disease and also counts among the 10 most frequent reasons for medical consultation. Its impact on quality of life (QoL) and work productivity has been established but comparisons with other diseases are rare in the literature. The aim of this study was to evaluate the impact of AR in health-related QoL (HRQoL) and work productivity in primary care patients, compared with other prevalent diseases such as hypertension, diabetes mellitus (DM) type II, and symptomatic depression. METHODS Six hundred sixteen patients were included in a multicenter cross-sectional observational study. A generic HRQoL questionnaire, 36-item Short Form, and a specific questionnaire, "Work Productivity and Activity Impairment" were handed out to measure QoL and work productivity impact of the diseases. To assess clinical severity with a comparable scale between diseases Clinical Global Impression (CGI) had been used. RESULTS Symptomatic depression was found to produce the greatest impairment on work productivity with a decrease of 59.5%, with significant differences compared with AR, hypertension, and DM type II (p < 0.05). Symptomatic depression was found to produce the highest negative impact on daily activities with a statistically significant reduction of 59.4% (p < 0.05) compared with AR (26.6% decrease), hypertension (8.8% decrease), and DM (16.7% decrease) patients. Differences between AR and DM or hypertension were also significant (p < 0.05). Restriction on daily activities for AR was 27.8%, which is significantly higher (p < 0.05) than hypertension (19.8% decrease) but not DM (25.7% decrease). Depression had the highest impairment on daily activities (59.4%), compared with the remaining three groups (p < 0.05). CONCLUSION AR impairs work productivity in a greater magnitude than hypertension and DM type II.

Abstract
Value-based insurance design (VBID) initiatives have been associated with modest improvements in adherence based on evaluations of administrative claims data. The objective of this prospective cohort study was to report the patient-centered outcomes of a VBID program that eliminated co-payments for diabetes-related medications and supplies for employees and dependents with diabetes at a large health system. The authors compared self-reported values of medication adherence, cost-related nonadherence, health status, and out-of-pocket health care costs for patients before and 1 year after program implementation. Clinical metrics and satisfaction with the program also are reported. In all, 188 patients completed the follow-up evaluation. Overall, patients reported a significant reduction in monthly out-of-pocket costs (P<0.001), which corresponded to a significant reduction in cost-related nonadherence from 41% to 17.5% (P<0.001). Self-reported medication adherence increased for hyperglycemic medications (P=0.011), but there were no apparent changes in glycemic control. Overall, 89% of participants agreed that the program helped them take better care of their diabetes. The authors found that a VBID program for employees and dependents with diabetes was associated with self-reported reductions in cost-related nonadherence and improvements in medication adherence. Importantly, the program was associated with high levels of satisfaction among participants and strongly perceived by participants to facilitate medication utilization and self-management for diabetes. These findings suggest that VBID programs can accomplish the anticipated goals for medication utilization and are highly regarded by participants. Patient-centered outcomes should be included in VBID evaluations to allow decision makers to determine the true impact of VBID programs on participants.

Abstract
BACKGROUND The need for an approach to measuring health results that incorporates patients' and payers' perspectives has generated a wide range of health care outcomes (HCOs), but it is yet unknown whether these HCOs are appropriate or valid for the health care decision-making process. OBJECTIVE The goal of this study was to assess HCOs, patient-reported outcomes (PROs), and economic outcomes in terms of validity and appropriateness to health care decision making in type 2 diabetes mellitus (T2DM). METHODS This systematic review of studies published between January 1, 1996, and November 1, 2010, comprised an electronic literature search of MEDLINE and Centre for Reviews and Dissemination databases. Studies included were clinical trials, observational studies, economic analyses, and studies on the development and validation of HCOs in T2DM in the adult population. HCOs were assessed and classified according to their relevance for decision makers in terms of feasibility for routine use, validity, sensitivity, reliability, understanding, and scope. RESULTS Two independent reviewers screened 4497 citations. Of these, 281 potentially eligible full articles were retrieved, and 185 met the inclusion criteria. A total of 121 HCOs in T2DM were identified: 80 (66.1%) PROs and 41 (33.9%) economic outcomes. Only 44.6% of the outcomes assessed were appropriate and valid for health care decision making. Greater deficiencies in evidence were found for PROs (61.3%), followed by economic outcomes (43.9%). CONCLUSIONS A large number of HCOs are being used in the health care decision-making process, but a significant proportion of these new outcomes have not been properly validated. Despite the fact that appropriate measures will depend on the specific needs of the decision makers, researchers need to use HCOs for which evidence of quality and appropriateness is available.

Abstract
This paper estimates the effect of diabetes on labor-force participation, hours worked, days-out-of-work due to illness, and earnings using data from the National Health Interview Survey. Findings indicate that diabetes, estimated wholly, is significantly detrimental to most labor market outcomes. However, separation of type I and II diabetes shows that much of the negative effect is due to type II diabetes. On average a female with type II diabetes can experience a wage penalty of almost 50% relative to a healthy individual. Additionally, estimates of specifically type II diabetes may be subject to endogeneity bias. To account for this, I utilize whether an individual's biological mother has been diagnosed with diabetes as an instrumental variable. This instrument provides both theoretical and statistical explanatory power to separate the causal effect of type II diabetes on labor-force decisions.

Abstract
The purpose of this study was to evaluate the relationships between diabetes and medical and dental care costs from a 5-yr prospective observation of Japanese workers. The data were derived from health and dental examinations and health insurance claims of 4,086 workers aged 40-54 yr. At baseline, the subjects were assigned to four categories: known diabetes; undiagnosed diabetes; impaired fasting glucose (IFG); and non-diabetic. The differences in health care costs among the non-diabetics, IFG and undiagnosed diabetes groups were not seen at baseline, but the costs incurred by the subjects with undiagnosed diabetes substantially increased thereafter. Over 5 yr of the study period, compared with the non-diabetic group, subjects with known diabetes incurred 3.9- and 2.9-fold higher annual inpatient and outpatient costs, respectively, while subjects in the undiagnosed diabetes group incurred 3.0- and 1.6-fold higher costs, respectively. There were no significant associations between annual dental care costs and diabetic status. The excess costs of medical care among subjects with diabetes were attributable to diabetes itself, heart disease and cerebrovascular disease, but not cancer. Among middle-aged workers, diabetics incurred significantly greater medical care costs than non-diabetics, whereas IFG was not associated with higher costs.

Abstract
OBJECTIVE To assess the incremental economic burden of privately insured patients with type 2 diabetes (T2DM) in 2000 and 2005 in the United States. METHODS Adults with T2DM and 24 months of continuous health plan enrollment were identified in the MarketScan databases (2000 and 2005). Control groups of persons without diabetes were selected for comparison using propensity score matching. Total adjusted health care costs were estimated using generalized linear modeling. RESULTS Adjusted health care costs of patients with T2DM in 2005 were 136% higher than those of the matched controls ($12,733 vs $5406, P < 0.001). Similarly, costs of patients with T2DM in 2000 were 146% higher than those of the matched controls ($12,423 vs $5058, P < 0.001). Expenditures were similar for individuals with T2DM in 2000 and 2005. CONCLUSIONS T2DM continues to impose a substantial economic burden to self-insured employers.

Abstract
AIMS To compare total costs and risk of hypoglycemia in patients with type 2 diabetes (T2D) initiated on NPH insulin versus glargine in a real-world setting. METHODS This study used claims data (10/2001 to 06/2005) from a privately insured U.S. population of adult T2D patients who were initiated on NPH or glargine following a 6-month insulin-free period. A sample of 1698 glargine-treated and 400 NPH-treated patients met the inclusion criteria. Total and diabetes-related costs (inflation-adjusted to 2006) were calculated for 6-month pre- and post-index periods and compared between 400 patient pairs matched by a propensity score method. RESULTS In the post-index 6-month period, glargine patients incurred higher diabetes-related drug costs than NPH patients ($785 versus $632, p<0.0001) but there were no significant differences in diabetes-related medical or total costs, or all other total cost categories. Compared to the pre-index period, glargine patient costs declined by $2420 (p=0.058) whereas NPH patient costs declined by $4200 (p=0.046), with no statistically significant group differences (p=0.469). Among patients with hypoglycemia-related claims (0.75% in both groups), mean hypoglycemia-related costs were $85 and $202 for NPH and glargine patients, respectively (p=0.564). CONCLUSION Initiation of either NPH or glargine was associated with major cost reductions and infrequent hypoglycemia-related claims.

Abstract
OBJECTIVES We predicted the future economic burden attributable to high rates of current adolescent overweight. METHODS We constructed models to simulate the costs of excess obesity and associated diabetes and coronary heart disease (CHD) among adults aged 35-64 years in the US population in 2020 to 2050. RESULTS Current adolescent overweight is projected to result in 161 million life-years complicated by obesity, diabetes, or CHD and 1.5 million life-years lost. The cumulative excess attributable total costs are estimated at $254 billion: $208 billion because of lost productivity from earlier death or morbidity and $46 billion from direct medical costs. Currently available therapies for hypertension, hyperlipidemia, and diabetes, used according to guidelines, if applied in the future, would result in modest reductions in excess mortality (decreased to 1.1 million life-years lost) but increase total excess costs by another $7 billion (increased to $261 billion total). CONCLUSIONS Current adolescent overweight will likely lead to large future economic and health burdens, especially lost productivity from premature death and disability. Application of currently available medical treatments will not greatly reduce these future burdens of increased adult obesity.

Abstract
OBJECTIVE To conduct the seventh periodic review and analysis of the clinical and cost-effectiveness research conducted in worksite/corporate environments between 2004 and 2008. METHODS A literature search of US-based research was conducted using a multistage process including MEDLINE, ADI, EDGAR, CARL, Inform, Lexis-Nexis, as well as direct inquiries to key researchers in this area of expertise. RESULTS From 2004 to 2008, there were 16 new studies that met the Inclusion/Exclusion criteria. These studies are critiqued and entered into a data table consisting of 13 variables and citations of the 16 new studies. CONCLUSIONS Clinical and cost-effectiveness research in the worksite/corporate environment continues to evolve although there was only one randomized clinical trial conducted during the most recent interval. There are innovations in pilot studies, quasi-experimental methodologies, and econometric modeling as indicative of future trends.

Abstract
OBJECTIVE To examine the effect of obesity and cardiometabolic risk factors on medical expenditures and missed work days. METHODS AND PROCEDURES The 2000 and 2002 Medical Expenditure Panel Survey (MEPS), a nationally representative survey of the US population, was used to estimate the marginal effect of obesity (BMI > or = 30) on annual per-person medical expenditures and missed work days for patients with diabetes, dyslipidemia, or hypertension using multivariate regression methods controlling for age, sex, race, ethnicity, education, income, insurance, and smoking status. Maximum Likelihood Heckman Selection with Smearing retransformation was used to assess medical expenditures, and Negative Binomial regression was used for missed work days. RESULTS Normal weight individuals with diabetes, dyslipidemia, or hypertension had significantly greater medical expenditures than those without the respective condition ($6,006 (5,124-6,887), $4,760 (4,102-5,417), $3,911 (3,345-4,476)) and obesity significantly exacerbated this effect ($7,986 (7,397-8,574), $7,636 (7,072-8,200), $6,197 (5,745-6,649); $2007; all P < 0.05). In addition, diabetes, dyslipidemia, and hypertension resulted in greater missed work days (3.1 (0.94-6.21), 3.2 (0.42-7.91), 1.4 (0.0-3.52)) (all P < 0.05 except hypertension), which resulted in greater lost productivity ($433, $451, $199) and obesity significantly exacerbated the deleterious effect on work days (8.7 (4.44-15.2), 5.5 (2.18-10.5), 4.5 (2.92-6.34)) and lost productivity ($1,217, $763, $622) (all P < 0.05). In addition, medical expenditures increased for increasing weight category and increasing number of risk factors. DISCUSSION Obesity significantly exacerbates the deleterious effect of diabetes, dyslipidemia, and hypertension on medical expenditures and productivity loss in the United States. Obesity is preventable and public health efforts need to be undertaken to prevent its alarming increase in order to reduce the incidence and effect of cardiometabolic risk factors.

Abstract
OBJECTIVE To examine, from the employer perspective, the direct (healthcare) and indirect (workloss) costs of employees with diabetic retinopathy (DR) compared to control non-DR employees with diabetes, and within DR subgroups. METHODS Compared annual costs using claims data from 17 large companies (1999-2004). 'DR employees' (n = 2098) had >or= 1 DR (International Classification of Disease, 9th Revision [ICD-9]) diagnosis; DR subgroups included employees with diabetic macular edema (DME), proliferative DR (PDR), and employees receiving photocoagulation or vitrectomy procedures. Descriptive and multivariate tests were performed. RESULTS DR employee annual direct costs were $18,218 (indirect = $3548) compared to $11,898 (indirect = $2374) for controls (Delta = $2032 (adjusted); p < 0.0001). Costs differences were larger across DR employee subgroups: DME/non-DME ($28,606/$16,363); PDR/non-PDR ($30,135/$13,445; p < 0.0001); DR with/without photocoagulation ($34,539/$16,041; p < 0.0001); and DR with/without vitrectomy ($63,933/$17,239; p < 0.0001). LIMITATIONS This study examined the incremental costs of treating DR employees, which may be higher than the incremental costs of DR itself. Some measures of diabetes severity (e.g., duration of diabetes) were not available in the claims data, and were therefore not included in the multivariate models. The cost of photocoagulation and vitrectomy procedures pertain to individuals who underwent these procedures, and not the cost of the procedures themselves. CONCLUSION DR employees had significantly higher costs than controls, and larger differences existed within DR subgroups. Indirect costs accounted for about 20% of total cost.

Abstract
OBJECTIVE Cardiometabolic risk factors such as overweight/obesity, hyperlipidemia, diabetes, and hypertension are prone to cluster together in the same individual and result in an elevated risk of cardiovascular disease and mortality. The purpose of this study was to examine and quantify the impact of cardiometabolic risk factor clusters independent of heart disease on productivity in a nationally representative sample of US adults. METHODS The current study estimated the impact of cardiometabolic risk factor clusters on missed work days and bed days, controlling for sociodemographic characteristics, comorbidity, and smoking status in a nationally representative, pooled 2000 and 2002 Medical Expenditure Panel Survey sample. Cardiometabolic risk factor clusters included BMI >or= 25 and two of the following three: diabetes, hyperlipidemia, and/or hypertension. All estimates were expressedin $US 2005. Sensitivity analyses were conducted to examine the impact of varying assumptions on the results. RESULTS After controlling for differences in sociodemographics, smoking and comorbidity, individuals with cardiometabolic risk factor clusters missed 179% more work days and spent 147% more days in bed (in addition to lost work days) than those without. Lost work days and bed days resulted in $17.3 billion annually in lost productivity attributable to cardiometabolic risk factor clusters in the United States. Sensitivity analyses resulted in a range of annual lost productivity costs from $3.2 to $23.1 billion. CONCLUSIONS Common cardiometabolic risk factor clusters have a significant deleterious impact on the US economy, resulting in $17.3 billion in lost productivity.

Abstract
BACKGROUND Obesity is highly prevalent among patients with type 2 diabetes. Unfortunately, weight gain may also be a consequence of some antidiabetic medications. Although clinical benefits of weight loss have been established, the economic consequence of weight change among patients with type 2 diabetes is unclear. OBJECTIVES The objective was to measure 1-year total and diabetes-related health care costs associated with weight change during the preceding 6-month period among type 2 diabetic patients on antidiabetic therapy. METHODS Administrative claims, electronic laboratory data and medical chart information were abstracted for continuously enrolled adults with type 2 diabetes from an health maintenance organization (HMO) for the period from July 1, 1997 through October 31, 2005. To assess the economic impact of weight change, three regression models were applied to estimate the following: (1) the effect of weight change in general (one-slope model); (2) the different effects of weight gain and no weight gain (two-slope model); and (3) the different effects of weight gain and no weight gain (i.e., no change or weight loss) among obese and non-obese patients (four-slope model). Patients included in the study had a baseline weight measurement and a second weight measurement approximately 6 months later. They were also required to be on at least one antidiabetic drug therapy within 1 month around the baseline weight measurement date (index date). Based on the measured weight change, patients were classified into two groups--weight gainers and non-weight gainer. Total health care cost and diabetes-related cost were measured during the 1-year period following the second weight measurement and were adjusted to 2004 dollars by the medical component of the Consumer Price Index (CPI). Generalized linear models with log link function and gamma distribution were applied to assess the impacts of weight change on the 1-year total health care cost as well as 1-year diabetes-related cost. All models controlled for patients' baseline demographics, comorbidities, body mass index (BMI), glycosylated hemoglobin (HbA1c), and prior resource utilization. RESULTS The study included 458 patients, of whom 224 (48.9%) experienced minimum weight gain of 1 pound between the two weight measurements. The average 1-year total health care cost following the second weight measure was $6382 and the diabetes-related cost was $2002. The mean total health care cost was $7260 for the weight-gainers and $5541 for the non-weight gainers (p = 0.046), and the mean diabetes-related cost, respectively, was $2141 and $1869 (p = 0.006). Results from the models showed that one percentage point of weight change was positively associated with a 3.1% ($213, p < 0.01) change in total health care cost. When weight gain and no gain were modeled separately, one percentage point of weight loss was associated with a 3.6% ($256, p < 0.05) decrease in total health care cost and a 5.8% ($131, p < 0.01) decrease in diabetes-related cost. However, one percentage point of weight gain was not associated with significant increase in either total health care or diabetes-related cost. Further, results from the model with interactions between weight change and obesity status revealed that the economic benefit of weight loss was more pronounced in the obese group (BMI > or = 30). Log likelihood ratio tests showed that the one-slope model for total health care cost and the two-slope model for diabetes-related cost are the appropriate models of choice. CONCLUSIONS Weight loss significantly reduced diabetes-related costs. Controlling for baseline factors in the regression model, the 1-year total health care cost following 1% weight loss (or gain) was $213 cost decrease (or increase). Diabetes-related cost did not appear to be associated with weight gain. Economic benefit of weight loss was evident among type 2 diabetic patients on antidiabetic therapy, especially among obese patients.

Abstract
OBJECTIVE Estimate the impact of diabetes and neuropathic pain on the US workforce. METHODS Data on lost productive time (LPT) was collected by telephone interview in a random sample of the US population (N=36,634). Of 19,075 occupation-eligible working adults included in the analysis, 1003 reported a physician diagnosis of diabetes; 38% of these reported numbness or tingling in feet or hands due to diabetes (symptom group). We compared diabetes respondents with and without symptoms to other respondents for LPT and related cost. RESULTS Health-related LPT was 18% higher in the symptom (P<0.05) and 5% higher in the non-symptom (P<0.05) groups versus for those without diabetes. The symptom group lost 1.4 hours of work per week more than the non-symptom group (P<0.05). CONCLUSIONS Workers who have diabetes with neuropathic symptoms lose the equivalent of $3.65 billion/yr in health-related LPT.

Abstract
OBJECTIVES This study estimates the costs to society of prescription opioid analgesic (RxO) abuse in the United States. METHODS Costs associated with RxO abuse were grouped into healthcare, criminal justice, and workplace categories. Costs were estimated by either (1) a quantity method that multiplies the number of RxO abusers derived from various national surveys by the estimated per abuser cost, or (2) an apportionment method that starts with overall (ie, prescription and nonprescription) drug abuse costs for a cost component (eg, police protection) and apportions the share of costs based on the prevalence of RxO abuse relative to overall drug abuse. Medical costs in excess of those for otherwise similar nonabusers were based on an analysis of a large administrative claims database for an employed population using multivariate regression methods. RESULTS A lower bound estimate of the costs of RxO abuse in the United States was 8.6 billion dollars in 2001 (or 9.5 billion dollars in 2005 dollars). Of this amount, 2.6 billion dollarswere healthcare costs, 1.4 billion dollars were criminal justice costs, and 4.6 billion dollars were workplace costs. CONCLUSIONS The costs of RxO abuse represent a substantial economic burden. Rising trends of RxO abuse suggest an escalating economic and public health burden in coming years in the United States, and potentially, elsewhere.

Abstract
BACKGROUND Diabetes is often associated with complications and comorbidities. The purpose of this research is to compare medical resources used by patients with the following diagnoses: diabetes mellitus (DM), diabetic neuropathy (DN), and diabetes mellitus combined with comorbid depression (DD). METHODS Adult patients who were diagnosed with DM, DN, or DD were included in the study. There were 55,972 patients in the DM cohort, 2,146 in the DN, and 2,379 in the DD. P values for comparisons between the three mutually exclusive cohorts were conducted using the Tukey-Kramer method. Cost comparisons among the cohorts were conducted using a stepwise multivariate regression that controlled for patient characteristics and comorbid conditions. RESULTS Individuals in the DM or DN cohorts were generally more likely to use antidiabetic medications than patients in the DD group. Those diagnosed with DN or DD generally used more pain medications than individuals in the DM cohort. The DM cohort had significantly lower diabetes-related total medical costs ($1,297 v $5,125, p < 0.0001) and lower total medical costs ($4,819 v $24,765, p < 0.0001) than the DN cohort. The DM cohort also had significantly lower diabetes-related total medical costs ($1,297 v $3,264, p < 0.0001) as well as significantly lower total medical costs ($4,819 v $19,298, p < 0.0001) than the DD cohort. CONCLUSION Results from this study indicated significant differences in demographic characteristics, comorbidities, and medication use among individuals diagnosed with DM, DN, or DD. These differences translated into significant cost differences. Patients diagnosed with DN or DD had higher diabetes-related costs than patients diagnosed with DM.

Abstract
AIMS/HYPOTHESIS The aim of this study was to identify the health care costs of diabetic patients in Germany in 2001, focusing on the influence of age, sex, and type of treatment. SUBJECTS AND METHODS Annual direct costs of medical care and indirect costs of inability to work and early retirement in diabetic subjects were compared with costs of age- and sex-matched non-diabetic control subjects. The analysis was based on routine health care data from a random sample (18.75%) taken from a database of 1.9 million insured persons. Incremental differences in medical and national expenditure between subjects with and without diabetes were calculated. RESULTS Annual direct mean costs per diabetic patient were 5,262 Euro, and indirect costs were 5,019 Euro. In the control group, mean direct and indirect costs were 2,755 Euro and 3,691 Euro, respectively. Analysis of cost components revealed that the high costs associated with the care of diabetic patients could be largely attributed to inpatient care and overall medication costs. Hypoglycaemic drugs amounted to only one-quarter of the medication costs. The total health care costs were correlated with the type of treatment. Direct excess costs increased with increasing age in insulin-treated patients, but were unaffected by age in patients receiving other types of treatment. CONCLUSIONS/INTERPRETATION The Costs of Diabetes Mellitus (CoDiM) study is the first comprehensive study to provide estimates of costs associated with diabetes care in Germany. Direct costs of diabetic patients account for 14.2% of total health care costs, which includes the proportion that specifically accounts for diabetes-related costs (6.8%).
