Surveys for assessing satisfaction with the distance learning courses of the Master’s Degree in Atherosclerosis Research

Introduction: COVID-19 caused the Ministry of Higher Education to indicate the interruption of face-to-face teaching activities. Subsequently, the master's degree in Atherosclerosis Research had to continue in the virtual modality. Objective: To validate survey design for assessing the satisfaction of master's degree students and professors with the virtual courses of the master's degree in Atherosclerosis Research. Methods: A qualitative research was conducted consisting of a review of the published literature to analyze the grounded theory in survey design and validation. Publications from 2017 were reviewed using the search, in which the following text chain was entered: design and validation of instruments to assess satisfaction with virtual courses. A documentary analysis was also conducted to analyze key concepts and ideas about the methods used for the development of this type of instrument, to consider problem situations and challenges of this design in other studies, as well as to learn about the different ways of approaching the research problem. For the design of the instruments, a pilot study was carried out with selected students and teachers. Results: The survey for the students consisted of twelve questions, while the professors had ten. The latter ones considered its quality as satisfactory. In the analysis of the results by authors and the overall assessment of both surveys carried out by the research group, two recommendations for improvement emerged, then included to make the final version of each instrument. Conclusions: Both surveys are easily adaptable for use in other virtual courses and in different virtual learning environments. Both instruments provide general data, information about the teacher, course content, bibliography and technological assurance. © 2022, Editorial Ciencias Medicas. All rights reserved.

Adverse reactions reported after the vaccine administration against covid-19 inworkers of aterciary hospital

Objectives: The COVID-19 disease is a public health emergency of international importance and vaccination is considered the best tool against it.

Making a description of the frequency, the presence in the technical sheet, the association with the history of infection by SARS-COV-2 and age. Methods: A retrospective descriptive study of the possible adverse reactions reported to the Occupational Risk Prevention Service of the hospital after the administration of the two doses of the vaccine for COVID-19 (Comirnaty®) was carried out in a sample of 8446 workers that received the first dose 1 and 8255 that received the second. A comparative analysis was performed by applying Pearson’s Chi-square test for qualitative variables and the Mann-Whitney test for quantitative variables. Results: The subjects who reported adverse reactions were 207 after dose 1 (2.45% of total vaccinated) and 397 after dose 2 (4.80% of total vaccinated). 76.8% were older than 55 years (dose 1) and 15.9% with dose 2. 57% had symptoms that were already described in the technical data sheet (dose 1) and 70.5% with dose 2. 50.7% had been previously diagnosed with COVID-19 (dose 1) and 30.5% with dose 2. Conclusions: The adverse reactions reported in our study have been mild or moderate, coinciding with the studies consulted. Adverse reactions were more frequent after the second dose. Among the workers who reported adverse reactions, there were more with a history of COVID-19, especially after the first dose. The reactions produced after vaccination and their causal relationship with it should continue to be studied. © 2021, Accion Medica S.A.. All rights reserved.
