Subject and scope: The aim of this paper was to analyze aldehyde content, specifically malonaldehyde, present in deep-frying oils used in food preparation in Universidad Santiago de Cali, its health effects during 2016-2017 and the transgression of the right to a healthy environment. Characteristics: An observational, descriptive, and cross-sectional study. Univariate and bivariate analysis was conducted. An Epi Info version 7.0 spreadsheet was used. The personnel working in the cafeterias of a higher education institution were interviewed and the constitutional norms were studied.Findings: The study found that there is a slight tendency to obtain higher values ​​in the pH measurements in the case of the new oils used in each of the establishments, but in the measurements of the reused oils, the pH were lower. Also, it is important to note that in any case the pH measurements for new oils were lower than the values ​​for used oils. When conducting the bivariate analysis between the sample mean value and the tba test, it was found that the higher the mean values, the tba test values ​​increased, with a Spearman correlation coefficient of 1 (perfect correlation).Conclusion: The evaluated parameters of pH, color, temperature and tba formation allowed to confirm the change in the qualities of the analyzed oils and the presence of malonaldehyde in the samples collected in the cafeterias and, also, in the replicas obtained in the laboratory, which generates expectations regarding the health of the population and requires decision-making by the institution.

Decision makers at the national and local level of health systems require evidence of effectiveness, safety and costs of health technologies for resource allocation. In this sense Health Technology Assessment (HTA) is a favorable tool considering it is a multidisciplinary process to evaluate the benefits as well as the social, economic, organizational and ethical issues of a health technology. The aim of this study was to review the literature in order to identify the attributes used in the process of technology acquisition. It was analyzed the attributes of HTA with the purpose of classifying them, to see which are the most recommended for acquisition in hospitals. The identified literature indicated that not only the clinical and economic attributes were considered, but also attributes related to the context of the hospital such as the effect of technology on other hospital services and others associated with the organization
