Background: There have been many studies on the cost of multiple sclerosis in countries with high prevalence, whereas in Latin America such analyses are few. Taking into consideration the burden of this disease and the high financial impact of treatment on the health care system, it is necessary to know the behavior of cost of illness. Objectives: To describe the direct costs associated with health care in patients with multiple sclerosis affiliated with a health insurer in Colombia. Methods: An analysis of direct costs of disease was performed from the perspective of the third-party payer. A direct measurement from the technical costing "top-down" approach was used. Data were adjusted for inflation and expressed in 2014 US dollars. Results: The average annual cost per patient for the country

AimTo evaluate the quality of oral fluorescein angiography (FA) in relation to food intake.MethodsThis is an observational, case-crossover study. We collected information from patients undergoing routine oral FA for retinal disease at the Shiley Eye Institute. Eighty patients (160 eyes) were analysed. Fasting and non-fasting images of the same patient were recorded, compared and analysed for different image quality parameters and clinical relevance by experienced retina specialists.ResultsWhen analysing the images, intergrader agreement was moderate to good with a Kappa averaging 0.60 (0.5–0.85). When patients were fasting pre-imaging, better angiography quality scores were achieved when compared with images taken when patients were non-fasting (mean 0.84 vs 0.72, p<0.001). Multivariate analysis showed that non-fasting patients with higher body mass index had the worst scores. Other clinical parameters, such as staining of drusen, staining of disciform scars or central and peripapillary atrophy, were also significantly better during the pre-fasting exam (p<0.001). Oral FA was approximately 22% faster (time to fluorescein dye appearance) under fasting conditions than non-fasting (mean±SD, minutes, 18.7±6.9 vs 25.14±8.1, p<0.001).ConclusionFasting oral FA provided significantly better quality images as well as faster optimal imaging times when compared with non-fasting oral FA. By improving its overall quality, oral FA could be a useful adjunctive examination to optical coherence tomography (OCT) and OCT angiography in patients who require FA studies but who have difficult access or refuse an invasive procedure.

Objective. To compare three antidepressant drugs from different classes used in treating moderate-to-severe major depressive disorder (MDD) in Colombian adults. Methods. Based on expert input, a decision-tree model was adapted for ABSTRACTDepression is a major health problem worldwide, ranking fourth globally as a health problem (1, 2). Latin America is no exception, and the problem may be even worse in that part of

HCP A is a very cost-effective option considering a threshold of 1 time the per-capita gross domestic product.

In Latin America, social security and public sectors represent the largest financiers and providers of health care. Many countries in the region have compulsory packages of basic health care benefits. As part of an effort to improve quality of care and access, several health technology assessment agencies, both governmental and academia, among a number of Latin American countries have been formally established in the past few years. Several Latin American countries have recently developed and published methodological guidelines in economic evaluation, indicating that there is a growing interest in evaluating health-related products, drugs, and technologies used by the population. Presentations on the health care system and the role of health technology assessment, pharmacoeconomics, and risk sharing policies, from the public sector perspective, in the Latin American countries Argentina, Brazil, Colombia, and Mexico were made at the 3rd Latin American ISPOR Conference held in Mexico City in 2011 and are discussed in this article. In conclusion, there is a clear need for Latin American countries to evaluate the value of new technologies that are being incorporated into their health care system. In addition, health technology assessment guidelines are important for their local needs in terms of regulation along with common country unions. In the future, the Latin American region needs to increase drug access along with implementing cost-containment measures to improve quality and health outcomes.

This analysis led to identifying medications whose formulation frequency did not correlate with an epidemiologic profile as immunomudulator and growth-hormone (somatotropin) agents. There were differences in the frequency and quantity of DDD medications authorised by type of affiliation which could thus be providing evidence of obstacles to the population having access to drugs/medicaments.
