Objective: The objective of this study was to determine the cost-effectiveness of zinc supplementation for the treatment of acute diarrhea (AD) in children younger than 5 years in Colombia. Methods: The cost-effectiveness analysis was performed from the perspective of the Colombian health system. The standard treatment with the addition of zinc was compared with the standard treatment without zinc in children younger than 5 years. The time horizon was 1 month. Effectiveness was extracted from a systematic review of literature. The specific data for Colombia were taken from local databases and observational studies. To determine the costs, a typical case was constructed by reviewing guidelines and medical records and validated by experts. To evaluate the resources consumed, Colombian tariff manuals were used. Costs were stated in Colombian pesos (COP) and US dollar (USD) for 2010. Deterministic sensitivity analysis was performed to evaluate the impact of changes in cost and effectiveness of the strategies on the results from the model. Results: The results from the model indicate that zinc supplementation is a dominant strategy; it is less costly and more effective than standard treatment without zinc (reduction of

15,210 COP [8.14 USD] per child). The results are sensitive to changes in the probability of hospitalization and of persistent diarrhea. Conclusions: Zinc for the treatment of AD is a highly cost-effective strategy and is recommended for inclusion in the benefit plan of the Colombian health system. This intervention is more cost-effective in children with a higher risk of persistent diarrhea and hospitalization.

INTRODUCTION Acute coronary syndrome is one of the most frequent medical emergencies in developing countries. OBJECTIVE To determine, from the perspective of the Colombian health system, the cost-effectiveness of ticagrelor compared to clopidogrel for the treatment of patients with acute coronary syndrome. MATERIALS AND METHODS We conducted a cost-effectiveness analysis from the perspective of the Colombian health system comparing ticagrelor and clopidogrel for the treatment of patients with acute coronary syndrome. To estimate the expected costs and outcomes, a Markov model was constructed in which patients could remain stable without experiencing new cardiovascular events, suffer from a new event, or die. For the baseline case, a 10-year time horizon and a discount ratio of 3% for costs and benefits were adopted. The transition probabilities were extracted from the PLATO (Platelet Inhibition and Patient Outcomes) clinical trial. Vital statistics were drawn from the Departmento Administrativo Nacional de Estadística (DANE) and additional information from Colombian patients included in the Access registry. To identify and measure resource use, a standard case was built by consulting guidelines and protocols. Unit costs were obtained from Colombian rate lists. A probabilistic sensitivity analysis was conducted in which costs were represented by a triangular distribution, and the effectiveness through a beta distribution. RESULTS In the base case, the additional cost per quality-adjusted life-year gained with ticagrelor was COP

28,411,503. The results were sensitive to changes in the time horizon and the unit cost of clopidogrel. For a willingness-to-pay equivalent to three times the Colombian per capita gross domestic product, the probability of ticagrelor being cost-effective was 75%. CONCLUSIONS Ticagrelor is a cost-effective strategy for the treatment of patients with acute coronary syndrome in Colombia.

OBJECTIVE To evaluate the costs of oral rehydration therapy (ORT) and nasogastric rehydration therapy (NRT) compared with intravenous rehydration therapy (IRT) to treat dehydration in children under 5 years of age with diarrhea. METHODOLOGY Cost-minimization analysis from the perspective of the Colombian Health System, comparing ORT, (followed by NRT when ORT fails), with IRT. The time horizon was the duration of rehydration. The effectiveness measure was obtained from a systematic review of the literature. To determine costs, a typical case was created based on current guidelines and medical records; this case was validated by experts. Unit costs were obtained from Colombian databases and were provided in Colombian pesos (COP) and US dollars (USD) for 2010. One- and two-way sensitivity analyzes were performed. RESULTS ORT and ERT are similarly effective to prevent hospitalization and to achieve rehydration. In the base case, the expected cost of ORT was

DISCUSSION Both interventions are similarly effective, but ORT, followed by NRT when ORT fails, is less costly than IRT. ORT is recommended as the first option to treat dehydration since it is effective and less expensive. Efforts should be continued to implement TRO and NRT in the health services of Colombia.
