Estimating cost-effectiveness thresholds under a managed healthcare system: experiences from Colombia.

Like most of the world, low- and middle-income countries have faced a growing demand for new health technologies and higher budget constraints. It is necessary to have technical instruments to make decisions based on real-world evidence that allows maximization of the population's health with a limited budget. We estimated the supply-based cost-effectiveness elasticity, which was then used to determine the cost-effectiveness threshold for the healthcare system of Colombia, a middle-income country where multiple insurers, paid under capitation rules, manage the compulsory contributions of the citizens and government subsidies. Using administrative data, we explored the variation of health expenditures and outcomes at the insurer, geographical region, diagnosis group and year levels. To deal with endogeneity in a two-way fixed-effects model, we instrumented health expenditures using characteristics of the health system such as drug-price regulation. We estimated the threshold to be US$4487.5 per years of life lost avoided [14.7 million Colombian pesos (COP) at 2019 prices] and US$5180.8 per quality-adjusted life-years gained (17 million COP at 2019 prices), around one times the gross domestic product GDP per capita. To the best of our knowledge, this is the first estimation of the cost-effectiveness threshold elasticity supply-based in a middle-income country with a managed healthcare system.

Cost of Patients With Hemophilia A and High-Titer Inhibitors in Colombia.

BACKGROUND: In Colombia, hemophilia is considered a high-cost disease, and hemophilia A with high-titer inhibitors may be responsible for a significant economic pressure on the Colombian health system. OBJECTIVES: To estimate the direct cost of care for patients with hemophilia A with high-titer inhibitors in Colombia, from the perspective of the health system. METHODS: A cost-of-illness study was carried out using standard case methodology, which was designed based on literature review and validation by expert consensus. Scenarios were established for adults and children, including cases of prophylaxis, immune tolerance induction, bleeding, and surgery. The frequencies were taken from the official report for Colombia, issued by the High-Cost Account 2017 (reported 2018). The prices were obtained from the list of regulated medicines in the country. The cost estimate is presented with a range of values by weight (between 10 kg and 90 kg). RESULTS: The total estimated cost per year for Colombia was US $44 905 252 (between US $32 260 497 and US $58 202 393). The average cost per year calculated for a patient was US $498 947 (between US $358 450 and US $646 693). A total of 99.8% of the estimated cost was directly related to the cost of the coagulation factors and bypassing agents. CONCLUSIONS: Hemophilia A with high-titer inhibitors is a disease that generates significant pressure on the Colombian health system, mainly linked to the cost of factors and bypassing agents.

Evaluación de la calidad de estudios farmacoeconómicos del uso de los inhibidores de la bomba de protones en enfermedad ácido péptica / Quality assessment of pharmacoeconomic studies of the use of proton pump inhibitors in peptic ulcer disease

Los inhibidores de la bomba de protones (IBP) son un grupo de fármacos que reducen la secreción de ácido en el estómago, por lo que son ampliamente utilizados en el tratamiento de la úlcera péptica. La notable prevalencia e incidencia de esta patología sugiere que los recursos económicos y humanos dedicados a su tratamiento son considerables y, por tanto, es necesario identificar fuentes fiables de información relacionadas con los costos y los beneficios de estos agentes terapéuticos que permitan valorarlos en términos de eficiencia para mejorar su prescripción racional. Este trabajo realizó una revisión de los estudios farmacoeconómicos correspondientes al uso de los ibp en la prevención y tratamiento de la enfermedad ácido péptica y se presenta una evaluación pareada de la calidad metodológica de la bibliografía basada en el instrumento qhes (Ofman et al., [10]). De los diez artículos revisados, cuatro son de costo-efectividad, dos de costo-utilidad, tres de descripción de costos y uno de minimización de costos. El puntaje global promedio obtenido por los estudios evaluados fue de 66,6 sobre 100. Cuatro de ellos puntuaron por debajo de 60, haciendo evidente deficiencias en la calidad de los estudios de acuerdo con el instrumento usado, además pone de manifiesto que se necesitan evaluaciones farmacoeconómicas en relación con el uso de los ibp para la prevención y el tratamiento de la úlcera péptica, especialmente estudios de costo-efectividad, que cumplan con los estándares de calidad metodológica.

Proton pump inhibitors (PPI) are a group of drugs that reduce gastric acid secretion and therefore are widely used in the treatment of peptic ulcer. The remarkable prevalence and incidence of this disease suggests that economic and human resources devoted to treatment are considerable and therefore it is necessary to identify reliable sources of information related to the costs and benefits of these therapeutic agents to appraise in terms of efficiency to improve rational prescribing. This paper conducted a review of pharmacoeconomic studies pertaining to the use of ppi in the prevention and treatment of peptic acid disease, as it presents a paired assessment of methodological quality of the literature instrument based on qhes (Ofman et al., [10]). Of the ten articles reviewed, four were cost-effectiveness, two cost-utility, three description of cost, and one of cost minimization. The average overall scored 66.6 out of 100. Four of them scored below 60.0, making it a clear need for pharmacoeconomic evaluations in connection with the use of ppi for prevention and treatment of peptic ulcer, especially cost-effectiveness studies that meet standards of methodological quality.
