Objective: To measure the economic burden of diabetes in Argentina by age, gender and region for the year 2005, in disability-adjusted life years (DALYs)., Methods: DALYs were estimated by the sum of years of life lost due to premature death (YLL) and years of life lived with disability (YLD)., Results: In the population studied (20 to 85 years), the burden of diabetes without complications was 1.3 million DALYs, 85% of which were caused by disabilities. Whereas mortality rates (YLL) increased as a function of age, YLD showed the opposite relationship. Women had higher burden of disease values, represented by 51 and 61% of YLL and YLD, respectively, independently of age., Conclusions: Our results demonstrate that disabilities are a key component of diabetes burden; its regular and systematic estimation would allow to design effective prevention strategies, to assess the impact of their implementation and to optimize resource allocation based on objective evidence.

Background: Diabetes is an expensive disease in Argentina as well as worldwide, and its prevalence is continuously rising affecting the quality of life of people with the disease and their life expectancy. It also imposes a heavy burden to the national health care budget and on the economy in the form of productivity losses., Aims: To review and discuss a) the reported evidence on diabetes prevalence, the degree of control, the cost of care and outcomes, b) available strategies to decrease the health and economic disease burden, and c) how the disease fits in the Argentinian health care system and policy. Finally, to propose evidence-based policy options to reduce the burden of diabetes, both from an epidemiological as well as an economic perspective, on the Argentinian society. The evidence presented is expected to help the local authorities to develop and implement effective diabetes care programmes., Methodology: A comprehensive literature review was performed using databases such as MEDLINE, EMBASE and LILACS (Latin American and Caribbean Health Sciences). Literature published from 1980 to 2011 was included. This information was complemented with grey literature, including data from national and provincial official sources, personal communications and contacts with health authorities and diabetes experts in Argentina., Results: Overall diabetes prevalence increased from 8.4% in 2005 to 9.6% 2009 at national level. In 2009, diabetes was the seventh leading cause of death with a mortality rate of 19.2 per 100,000 inhabitants, and it accounted for 1,328,802 DALYs lost in the adult population, mainly affecting women aged over fifty. The per capita hospitalisation cost for people with diabetes was significantly higher than for people without the disease, US$ 1,628 vs. US$ 833 in 2004. Evidence shows that implementation of combined educative interventions improved quality of care and outcomes, decreased treatment costs and optimised the use of economic resources., Conclusions: Based on the evidence reviewed, we believe that the implementation of structured health care programmes including diabetes education at every level, could improve quality of care as well as its clinical, metabolic and economic outcomes. If implemented across the country, these programmes could decrease the disease burden and optimise the use of human and economic resources.

Objectives: To estimate the cost-consequence of interventions to prevent hospitalizations for heart failure (HF) in people with type 2 diabetes., Methods: In HF events (63) from type 2 diabetes-related hospitalizations (N = 462) recorded in an Argentine hospital (March 2004-April 2005), we verified 1) the presence of one metabolic HF predictor (glycosylated hemoglobin [HbA1c] value) before hospitalization; and 2) in a simulation model, the resources needed for its prevention controlling such predictor during 6 months before and after the event. Sensitivity analysis of HF risk reduction, hospitalization cost, and cost of different treatments to achieve HbA1c 7% or less was performed with a Monte Carlo simulation (10,000 iterations)., Results: HF represented 14% of hospitalizations, with a 44% rehospitalization rate for the same cause. Due to the total estimated cost for an HF hospitalization event was $437.31, the prevention attained using our simulated treatment was $2326.51. The number needed to treat to prevent an HF event under any of the proposed alternatives to reduce HbA1c would be 3.57 (95% confidence interval 2.00-16.67). The additional cost of the simulated treatment versus the real one oscillates between $6423.91 and $8455.68., Conclusions: HbA1c control to reduce the number of HF events would be economically beneficial for health care payers., (Copyright © 2011 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Objective: To estimate individual and household economic impact of cardiovascular disease (CVD) in selected low- and middle-income countries (LMIC)., Background: Empirical evidence on the microeconomic consequences of CVD in LMIC is scarce., Methods and Findings: We surveyed 1,657 recently hospitalized CVD patients (66% male; mean age 55.8 years) from Argentina, China, India, and Tanzania to evaluate the microeconomic and functional/productivity impact of CVD hospitalization. Respondents were stratified into three income groups. Median out-of-pocket expenditures for CVD treatment over 15 month follow-up ranged from 354 international dollars (2007 INT$, Tanzania, low-income) to INT$2,917 (India, high-income). Catastrophic health spending (CHS) was present in >50% of respondents in China, India, and Tanzania. Distress financing (DF) and lost income were more common in low-income respondents. After adjustment, lack of health insurance was associated with CHS in Argentina (OR 4.73 [2.56, 8.76], India (OR 3.93 [2.23, 6.90], and Tanzania (OR 3.68 [1.86, 7.26] with a marginal association in China (OR 2.05 [0.82, 5.11]). These economic effects were accompanied by substantial decreases in individual functional health and productivity., Conclusions: Individuals in selected LMIC bear significant financial burdens following CVD hospitalization, yet with substantial variation across and within countries. Lack of insurance may drive much of the financial stress of CVD in LMIC patients and their families.

Objective: To test diabetes-related attitudes of health care team members (HCTMs) and people with diabetes in a developing country, in this case, Argentina., Methods: The third version of the Diabetes Attitudes Scale (DAS-3) was randomly administered, in person, to 252 HCTMs (nurses, nutritionists, physicians, podiatrists, and social workers) and 279 people with type 1 or type 2 diabetes mellitus in several provinces of Argentina in 2004. Data from 531 completed questionnaires were included in the study. The data were statistically analyzed using analysis of variance, covariance, chi-square, and t-tests., Results: Although few, the differences in attitudes of HCTMs and people with diabetes were significant. The two groups expressed only slight agreement on DAS-3 statements such as "seriousness of type 2 diabetes," "value of tight control," and "psychosocial impact of diabetes;" and disagreed completely on "patient autonomy." No significant differences were recorded between people with type 1 or type 2 diabetes regarding "seriousness of the disease," but from both groups, those individuals who had previously attended a diabetes education course assigned this statement a higher score (P<0.01)., Conclusions: The unfavorable trend among the participants, similar to that recorded in developed countries, would contribute to the poor treatment outcomes observed in people with type 2 diabetes. Changing these attitudes by means of education could contribute to improving the quality of care and of life for people with diabetes and to decreasing the cost of the disease.

Objective: To implement a controlled clinical trial (PRODIACOR) in a primary care setting designed 1) to improve type 2 diabetes care and 2) to collect cost data in order to be able to measure cost-effectiveness of three system interventions (checkbook of indicated procedures, patient/provider feedback and complete coverage of medications and supplies) and physician and/or patient education to improve psychological, clinical, metabolic and therapeutic indicators. All three Argentinean health subsectors (public health, social security and the private, prepaid system) are participants in the study. Patients of participating physicians were randomly selected and assigned to one of four groups: control, provider education, patient education, and provider/patient education; the system interventions were provided to all four groups., Baseline Results: Mean BMI was 29.8 kg/m(2); most subjects had blood pressure, fasting glucose and total cholesterol above targets recommended by international standards. Only 1% had had microalbuminuria measured, 57% performed glucose self-monitoring, 37% had had an eye examination and 31% a foot examination in the preceding year. Ten percent, 26% and 73% of people with hyperglycemia, hypertension and dyslipidemia, respectively, were not on medications. Most patients treated with either insulin or oral antidiabetic agents were on monotherapy as were those treated for hypertension and dyslipidemia. WHO-5 questionnaire scores indicated that 13% of the subjects needed psychological intervention., Conclusions: Baseline data show multiple deficiencies in the process and outcomes of care that could be targeted and improved by PRODIACOR intervention.

Objective: To analyze and compare the ambulatory care expenditures for persons with diabetes during prehospitalization and posthospitalization periods with those of diabetics who were not hospitalized for diabetes-related illnesses during the same period., Methods: We determined the hospitalization and ambulatory care expenses incurred by an Argentine health insurer for the hospitalization of diabetic clients during the study period, and compared these expenses to the expenses of insured diabetics who were not hospitalized during that period., Results: We identified 2,760 persons with diabetes (2.4% of the total number of persons covered by the insurance company). Of those, 1,683 (59%) were on medication for diabetes and its associated cardiovascular risk factors. Diabetes was associated with either one (41%) or two (24%) cardiovascular risk factors. Of those 1 683 persons, 102 (6%) were hospitalized for diabetes-related reasons during the study period. The frequency of hospitalization increased significantly in cases where diabetes was associated with arterial hypertension and dyslipidemia. Cardiovascular illness was the cause of 43.1% of the hospitalizations, with a significantly higher per capita cost than any of the other causes identified (mean +/- standard error of the mean: US 1,673 dollars +/- US 296.8 dollars; P < 0.05). The total annual per capita cost for health care for the diabetics who had been hospitalized was greater than for those who had not (US 2,907.8 dollars +/- US 262.5 dollars compared to US 473.4 dollars +/- US 9.8 dollars, respectively; P < 0.01). While the total posthospitalization ambulatory care expenditures were 12% higher than the prehospitalization costs (US 903.6 dollars +/- US 108.6 dollars vs. US 797.6 dollars +/- US 14.9 dollars), the difference was not significant., Conclusion: Ambulatory care expenditures increase significantly in the prehospitalization and posthospitalization periods. The results suggest that intensive treatment of hyperglycemia and its associated cardiovascular risk factors may prevent hospitalization and is a more cost-effective option than hospitalization and posthospitalization ambulatory care.

Objective: In PROPAT we implemented an integrated approach to diabetes care designed to improve the quality and reduce the cost of care., Study Design and Methods: PROPAT was a case-control study matching patients by age and gender (diabetes:control ratio 1:2) within IOMA, a public employment-based health maintenance organization (HMO) of the Province of Buenos Aires, Argentina. Costs were evaluated using prevalence data from an HMO perspective. We currently report clinical and biochemical data and costs from the first 297 patients enrolled who completed 1 year in PROPAT, and compare them with those derived from control patients., Results: All recommended practices recorded as care provided at baseline increased significantly 1 year after implementing PROPAT, with a parallel significant improvement in several clinical and biochemical parameters, and markedly lower total annual per capita costs., Conclusions: These results demonstrate that the implementation of a comprehensive diabetes care program can simultaneously improve quality while reducing costs.

Objective: To examine the prevalence, characteristics, and costs of hospitalization and re-hospitalization of diabetic and non-diabetic patients in La Plata, Argentina, and to compare the data with those of developed countries., Research Design and Methods: We studied all in-hospital registries of diabetic patients enrolled in a health maintenance organization of the Province of Buenos Aires (IOMA, November 1996). For each diabetic patient (127 persons), the characteristics of two other hospitalized non-diabetic patients matched by age and gender were simultaneously recorded., Results: Of the 2200 recorded hospitalizations, 5.8% were for diabetic patients, accounting for 10.5% of the hospitalization cost. Cardiovascular diseases were the major cause of hospitalization in both groups. The per capita hospitalization cost of diabetic patients was significantly higher: 1628.5+/-1754.0 US dollars versus 833+/-842 US dollars; P=0.00002. Percent re-hospitalizations were five and a half times higher in diabetic patients (P=0.0001), and significantly associated with history of severe episodes of acute (odds ratio: 3.61; 95% CI: 1.11-11.70; P=0.03) and chronic (odds ratio: 4.26; 95% CI: 1.60-11.29; P=0.004) complications., Conclusions: The combination of higher and longer hospitalization rates and frequent re-hospitalizations resulted in increased costs for our diabetic population. Implementation of care programs based on education (for physicians and patients) could effectively decrease current and future costs of the disease.
