[Comparative economic evaluation of renal replacement therapies in Argentina, Costa Rica, and UruguayAvaliação econômica comparativa de terapias de substituição renal na Argentina, na Costa Rica e no Uruguai]. / Evaluación económica comparativa sobre terapias de reemplazo renal en Argentina, Costa Rica y Uruguay.

OBJECTIVE: Evaluate differences in the cost and prevalence of renal replacement therapies (RRTs) such as transplants, peritoneal dialysis, and hemodialysis in Argentina, Costa Rica, and Uruguay, based on cost-effective dissemination strategies. METHODS: Costs and prevalence obtained from the main financers and providers in each country; analysis of cost-effectiveness using a Markov model with a five-year horizon, evaluating resource allocation strategies for their incremental cost-effectiveness ratio expressed as quality-adjusted years of life. RESULTS: There is observed dispersion among countries in terms of access to and beneficial value of RRTs, affecting their prevalence and monetary breakeven point. From the cost standpoint, it is more efficient to promote transplants and peritoneal dialysis, and to discourage hemodialysis, although the availability of each RRT in each country required a specific evaluation. CONCLUSIONS: Promoting transplants saves costs, but the variable breakeven points make it necessary to determine different cost-effectiveness thresholds for each country. In Argentina and Uruguay, RRTs would be more cost-effective with an increase in the number of patients in peritoneal dialysis and higher donation rates for transplants. In Costa Rica (where there is a high transplant rate and large budgetary margin), the use of dialysis is aligned with demand and with the incidence of patients with terminal chronic kidney disease.

OBJETIVO: Avaliar as diferenças de custos e prevalência das terapias de substituição renal (TSR) como o transplante, a diálise peritoneal e a hemodiálise na Argentina, na Costa Rica e no Uruguai, mediante estratégias de difusão custo-efetivas. MÉTODOS: Foram avaliados custos e prevalência dos principais financiadores e prestadores por país, e realizada análise de custo-efetividade mediante modelo de Markov para 5 anos, avaliando estratégias de alocação de recursos expressas pela razão de custo-efetividade incremental por ano de vida ajustado por qualidade. RESULTADOS: Foi observada, entre os países, dispersão no acesso e nos valores prestacionais de TSR, afetando sua prevalência e o ponto de equilíbrio monetário. Do ponto de vista dos custos, é mais eficiente promover a realização de transplantes e de diálise peritoneal e desestimular a indicação de hemodiálise, embora a disponibilidade de cada TSR por país tenha exigido avaliações específicas. CONCLUSÕES: Promover a realização de transplantes economiza custos, embora os pontos de equilíbrio variáveis requeiram a determinação de diferentes limiares de custo-efetividade por país. Na Argentina e no Uruguai, a administração de TSR melhoraria sua eficiência se a quantidade de pacientes em diálise peritoneal e as taxas de doação para transplantes aumentassem. Na Costa Rica (onde há taxas elevadas de transplantes e margem orçamentária), a incorporação de técnicas dialíticas é ajustada por demanda e incidência de pacientes com DRCT.

Evaluación económica comparativa sobre terapias de reemplazo renal en Argentina, Costa Rica y Uruguay

[RESUMEN]. Objetivo. Evaluar las diferencias de costos y prevalencia de las terapias de remplazo renal (TRR) como el trasplante, la diálisis peritoneal y la hemodiálisis en Argentina, Costa Rica y Uruguay, mediante estrategias costo-efectivas de difusión. Métodos. Costos y prevalencia de principales financiadores y prestadores por país, y análisis de costo- efectividad mediante modelo de Markov a 5 años, evaluando estrategias de asignación de recursos expresa-das por razón incremental de costo-efectividad en costo por año de vida ajustado por calidad. Resultados. Se observa dispersión entre los países en el acceso y los valores prestacionales de TRR, que afectan su prevalencia y el punto de equilibrio monetario. Desde el punto de vista de los costos, es más eficiente promover la realización de trasplantes y de diálisis peritoneal, y desalentar la indicación de hemodiálisis, aunque la disponibilidad de cada TRR por país requirió evaluaciones particulares. Conclusiones. Promover la realización de trasplantes ahorra costos, aunque los puntos de equilibrio variables requieren determinar diferentes umbrales de costo-efectividad por país. En Argentina y Uruguay, la administración de TRR mejoraría su eficiencia si se aumentan la cantidad de pacientes en diálisis peritoneal y las tasas de donación para trasplantes. En Costa Rica (donde hay tasas elevadas de trasplantes y margen presupuestario), la incorporación de técnicas dialíticas se ajusta por demanda e incidencia de pacientes con ERCT.

Epidemiology and control of hypertension and diabetes in Costa Rica.

Costa Rica is one of the countries that make up Central America, neighboring Nicaragua and Panama. Costa Rica shares with its neighbors the social and economic problems characteristic of developing countries; however, one difference is that Costa Rica can derive a great part of its budget and expense to health and education, as it had abolished the army in 1948. It is for this reason that Costa Rica shares diseases characteristic of their region like the Dengue, yet at the same time have a true explosion in the fields of hypertension (HTA), diabetes (DM), and cardiovascular disease. The health system of Costa Rica has nearly universal coverage, reaching 98% of the population with primary and secondary diverse levels of attention that give appropriate and satisfactory treatment to all hypertensive and diabetic patients. The HTA and the DM are true public health problems; however, before 2004, there weren't appropriate data on their prevalence and management. Small studies showed an increase in the prevalence of HTA from 9 to 24%, though no data on the prevalence of DM were available. In 2004, the Multinational Survey of Diabetes and Hypertension and Other Factors of Risk carried out in San José, Costa Rica, determined a prevalence of HTA of 25% and of DM of 8%. Likewise, the methodology of the survey allowed an evaluation of the quality of the attention of the HTA (Tracer of Arterial Hypertension) and, consequently, appropriate control of hypertensive patients in Costa Rica; through it, it was determined that greater effort was required for earlier detection and resource optimization to better handle hypertensive and diabetic patients and thus reduce cardiovascular morbidity-mortality and chronic renal disease.

Chronic kidney disease in Costa Rica.

Costa Rica is one of the Central American countries, located between Nicaragua to the north and Panama to the south. Like other Latin American countries, Costa Rica deals with social and economic problems associated with poverty, except for one significant difference-Costa Rica has not had an army since 1948, and so the people and government can spend more money on education and health. For this reason, Costa Rica is very different from other Latin American countries. We do not need weapons, and we have had a democratic tradition for 100 years. Despite our economic and social limitations, Costa Ricans have universal access to a health system that covers 98% of the inhabitants. Renal replacement therapy (RRT) is accessible to all who need it. In the last 5 years, Costa Rica has doubled the number of patients on hemodialysis, and has the highest number of kidney transplants per million population (pmp) in Latin America, with 20.63 transplants pmp in 2000, 27.25 transplants pmp in 2001, and 24.81 transplants pmp in 2002. However, the prevalence of all forms of RRT in Costa Rica is currently 193 pmp. This suggests that end-stage renal disease is underdiagnosed in Costa Rica as it is in many other Latin American countries. Greater research efforts are needed to determine the true extent of renal disease in Costa Rica and to optimize the use of health-sector resources to provide a better and more robust program of RRT for patients with end-stage renal disease.
