Efeitos de um treinamento em ventilação mecânica para enfermeiros, fundamentado no método de ensino da instrução programada

Abstract

The objective of the present dissertation was to evaluate the effectiveness of training in mechanical ventilation, based on the principles of programmed instruction, for nurses who work in the sectors of a university regional hospital in southern Brazil. This is a quasi-experimental research, with a pre and postintervention assessment of a single group, carried out with nurses at a Regional University Hospital in the Northwest of the state of Paraná, from June to September 2022. Data collection took place in three moments, called pre-test, immediate post-test and late post-test, the latter occurring three months after the initial training. The Statistical Package for Social Science (SPSS) for Windows was used for analysis, with application of the paired t-test and Friedman test with significance < 0.05, and Post-hoc Durbin-Conover test. For analysis of the questionnaire, Cronbach's alpha coefficient was used. The study was approved by the permanent committee for ethics in research with human beings, with opinion nº 5,156,142. In the pre-test, 51 nurses participated, 45 nurses in the immediate post-test and 30 nurses in the late post-test. The average age of the participants was 42 years old and approximately half of the sample (45%) had a dual employment relationship. Regarding experience in previous trainings related to the theme, 64% had never participated. It was evidenced that from the first to the second stage, the average of correct answers in the training increased, as well as from the second to the third stage of the training carried out after three months of practical application. The pre-test averaged 8.73 correct answers with a standard deviation of 2.21; the immediate post-test had an average of 12.4 correct answers with a standard deviation of 1.87 and the delayed post-test had an average of 10.7 correct answers with a standard deviation of 2.21. Friedman's test resulted in a p-value <0.01 and Cronbach's alpha showed that the questionnaire was more reliable in the late post-test. The training was effective, but it was not enough to achieve a retention of knowledge that lasted longer, a fact that justifies the need for periodic theoretical and practical training on the subject.
