Carga económica de la hipercolesterolemia en población con alto riesgo cardiovascular en México / Economic burden of hypercholesterolemia in high risk of cardiovascular disease population in Mexico

Resumen Objetivo: Se estimó la carga económica directa e indirecta de la hipercolesterolemia en población con alto riesgo de presentar un evento cardiovascular. Para ello se definieron específicamente cinco grupos de pacientes: 1) aquellos con hipercolesterolemia familiar; 2, 3 y 4) personas con hipercolesterolemia más el antecedente de diabetes, infarto o evento vascular cerebral; 5) pacientes con hipercolesterolemia más diabetes y antecedente de infarto agudo de miocardio (definidos como pacientes de muy alto riesgo cardiovascular). Los cálculos se hicieron desde la perspectiva de las instituciones de salud pública en México. Método: Para la estimación de los costos directos se incluyó la atención ambulatoria, el tratamiento farmacológico, la atención hospitalaria y las intervenciones quirúrgicas relacionadas con las enfermedades cardiovasculares. Para la carga económica indirecta, se consideraron las muertes reportadas específicamente por causa de hipercolesterolemia, en un momento anterior al final de la edad productiva (muerte prematura). Resultados: La carga económica directa de las cinco categorías de pacientes en riesgo consideradas es de MXN $39,601,464,154 (USD $1,987,526,432), mientras que la carga económica indirecta asciende a MXN $121,646,689 (USD $6,105,229). Conclusiones: El impacto económico de la hipercolesterolemia en población con alto riesgo cardiovascular correspondía a $39,723,110,843 en 2020 (equivalente a USD $1,993,631,661), equivalente al 0.16% del PIB nacional.

Abstract Objective: To estimate the direct and indirect economic burden of hypercholesterolemia in patients with high risk of a cardiovascular event, specifically there were defined 5 groups of patients: 1) familial hypercholesterolemia; 2, 3 and 4) patients with hypercholesterolemia and background of diabetes, myocardial infarction or stroke; 5) diabetes, myocardial infarction and hypercholesterolemia (very high-risk patients) from the Mexican public healthcare institutions. Methods: For the estimation of the direct costs the items included correspond to: outpatient care, pharmacological treatment, inpatient hospital care, and surgical procedures. For indirect economic burden, death certificates, before the end of the productive age due to hypercholesterolemia were calculated (premature mortality). Results: The direct economic burden for the 5 groups of patients at risk is MXN $39,601,464,154 (USD $1,987,526,432), while the indirect economic burden amounts to MXN $121,646,689 (USD $6,105,229). Conclusions: The economic impact of hypercholesterolemia in patients with high cardiovascular risk is $39,723,110,843 (equivalent to USD $1,993,631,661) and corresponds to the 0.16% of GDP.

Cost-effectiveness of a self-management and comprehensive training intervention in patients with type 2 diabetes up to 5 years of diagnosis in a specialized hospital in Mexico City.

INTRODUCTION: To assess the cost-effectiveness of a multidisciplinary and comprehensive innovative diabetes care program (CAIPaDi) versus usual treatment in public health institutions. RESEARCH DESIGN AND METHODS: Using a cost-effectiveness analysis, we compared the CAIPaDi program versus usual treatment given in Mexican public health institutions. The analysis was based on the IQVIA Core Diabetes Model, a validated simulation model used to estimate long-term clinical outcomes. Data were prospectively obtained from the CAIPaDi program and from public databases and published papers. Health outcomes were expressed in terms of life-years gained and quality-adjusted life years (QALYs). Health and economic outcomes were estimated from a public perspective and discounted at 5% per year over a 20-year horizon. Costs are reported in US dollars (US$) of 2019. A probabilistic sensitivity analysis was performed using life-years gained and QALYs. RESULTS: The CAIPaDi costs on average US$559 (95% CI: -$879 to -$239) less than the usual treatment (95% CI: -$879 to -$239) and produced a difference in mean life-years gained (0.48, 95% CI: 0.45 to 0.52) and mean QALYs (1.43, 95% CI: 1.40 to 1.46). The cost-effectiveness ratio resulted in a saving per life-year gained of -US$1155 (95% CI: -$1962 to -$460). Mean differences in QALYs resulted in a saving per QALY of -US$735 (95% CI: -$1193 to -$305). Probabilistic sensitivity analysis proved the results are robust on both life-years gained and QALYs. CONCLUSIONS: CAIPaDi has a better cost-effectiveness ratio than the usual therapy in Mexican public health institutions.

Cost-effectiveness of the use of the continuous subcutaneous insulin infusion pump versus daily multiple injections in type 1 diabetes adult patients at the Mexican Institute of Social Security.

BACKGROUND: To estimate the incremental cost-effectiveness ratio (ICER) of the use of continuous subcutaneous insulin infusion (CSII) therapy versus multiple daily injections (MDI) therapy in adult patients with type 1 diabetes (T1D) at the Mexican Institute of Social Security (IMSS). METHODS: An analysis was developed using the internationally validated Core Diabetes Model (CDM) with which the incidence and progression of acute and chronic complications and the mortality of T1D was simulated throughout life. The baseline characteristics of the simulated cohorts were obtained from Mexican T1D adult patients aged ≥ 18 years that received care at two national IMSS medical centres in 2016. In the base case, the costs of the complications and treatment of the disease with both therapies were estimated in Mexican currency from the perspective of the institution, using Diagnosis Related Groups for outpatient and inpatient care. Utilities were taken from the international bibliography. In a secondary analysis, indirect costs were included using a human capital approach. The model used a lifetime time horizon, and a discount rate of 5% was applied for health outcomes and costs. A one-way sensitivity analysis was conducted on key variables and patient sub-groups; uncertainty was evaluated using a Cost-Effectiveness Acceptability Curve. RESULTS: The average age of the cohort was 32 years, with diabetes duration of 19 years, an average HbA1c of 9.2%; 29% were men. A gain of 0.614 Quality Adjusted Life Years (QALYs) was estimated with the use of CSII therapy. The estimated ICER was MXN$478,020 per QALY in the base case, and MXN$369,593 when indirect costs were considered. The sensitivity analysis showed that, in adult patients with HbA1c > 9.0%, the ICER was MXN$262,237. CONCLUSIONS: This is the first economic evaluation study that compares CSII therapy versus MDI therapy for T1D adult patients in Mexico. The insulin pump therapy can be considered cost-effective in the context of the IMSS when considering a threshold of three GDPs per capita with 43.9% probability. Results improve substantially when patients have an HbA1c above 9%.

[Economic impact of hemophilia type A and B in Mexico]. / Impacto económico de la hemofilia tipo A y B en México.

BACKGROUND: The treatment of hemophilia generates a disproportionally large economic impact relative to its prevalence. OBJECTIVE: To determine the economic impact of hemophilia A and B in Mexico in 2011 from the perspective of public health institutions. METHODS: Hemophilia was epidemiologically characterized in Mexico during the year of interest, direct costs (diagnosis, monitoring or follow-up, care of bleeding events, and consumption of hemostatic factors), as well as absenteeism associated with illness (indirect costs) were estimated. Records, surveys and official data were supplemented by expert opinion to assess costs. RESULTS: The investment in hemostatic factors is the primary source of cost: 68.6 and 74.3% of total investment in hemophilia A and B, respectively. Sensitivity analysis showed that the most decisive variable is the cost of acquisition of hemostatic factors, including bypass agents. The second most important source of cost is the attention to bleeding events, being significantly higher in patients receiving on-demand treatment compared with those receiving prophylaxis. CONCLUSION: In Mexico, hemophilia is a condition whose treatment requires a large amount of financial resources associated with the cost of hemostatic factors and care of hemorrhage, the latter being lower in patients on prophylaxis relative to on-demand.

[HIV/AIDS care and prevention expenditures in Mexico: trends and estimations 1997-2002]. / El gasto en la atención y la prevención del VIH/SIDA en Mexico: tendencias y estimaciones 1997-2002.

OBJECTIVE: This paper first presents the trend of HIV/AIDS expenditures in Mexico between 1997 and 2002. It then compares the allocation and magnitude of such expenditures within the international context and, in particular, how other countries in the region are allocating HIV/AIDS resources. MATERIAL AND METHODS: Since 1997, Mexico has developed and been utilizing a method for systematically and comprehensively analyze national resource and expenditure flows for HIV/AIDS prevention and care; an exhaustive study known as the National AIDS Account. Results. During this five year period, a systematic increase in real expenditures occurred (143% increase in total), most of which was allocated to the purchase of drugs for antiretroviral treatment. Nevertheless, compared with other countries in the region, Mexican expenditures for HIV/AIDS are less biased in their allocation between prevention and treatment. DISCUSSION: Mexico is committed to ensure universal coverage of AIDS treatment while maintaining and even increasing prevention efforts. These activities demand increasing amounts of resources. It is, therefore, important to track how efficiently such resources are being used in order to improve allocation and targeting of health resources.

El gasto en la atención y la prevención del VIH/SIDA en México: tendencias y estimaciones 1997-2002 / HIV/AIDS care and prevention expenditures in Mexico: trends and estimations 1997-2002

OBJETIVO: Presentar un análisis de la tendencia seguida por el gasto ejercido en el combate de la epidemia de VIH/SIDA en México durante el periodo 1997-2002, contrastando el gasto y la distribución actual con las proyecciones internacionales y la situación imperante en otros países de la región. MATERIAL Y MÉTODOS: A partir de 1997, y durante tres bienios consecutivos, se ha desarrollado el análisis contable, sistematizado y exhaustivo de los flujos de financiamiento y gasto orientados al suministro de bienes y servicios relacionados con la atención y la prevención del VIH/SIDA, ejercicio denominado Cuentas Nacionales de SIDA. RESULTADOS: Se observa un incremento real y sostenido en el gasto total destinado al combate de la epidemia, estimado en 143 por ciento y ejercido en diferentes rubros, pero particularmente en el gasto en medicamentos antirretrovirales. No obstante, comparado con otros países de la región, el gasto mexicano en VIH/SIDA tiene un menor sesgo en cuanto a la asignación entre prevención y tratamiento. DISCUSION: El gobierno mexicano se ha comprometido a garantizar el acceso universal al tratamiento antirretroviral para los pacientes con VIH/SIDA que lo necesiten y, al mismo tiempo, a mantener e incluso aumentar los esfuerzos en prevención. Estas actividades demandan incrementos en los recursos destinados para combatir la epidemia, por lo que es importante dar seguimiento a la eficiencia con que se estén utilizando los mismos, de forma que se pueda mejorar su asignación y focalización.
