Detailed Description

Asthma is one of major causes of morbidity and mortality due to chronic diseases worldwide with higher mortality and morbidity in adolescents. Interventions directed to adolescents and systematically developed within the school environment has been performed around the world. In spite of that, studies such Bruzzese (2004; 2011) have already shown that clinical interventions associated with educational activities in group composed of individuals with similar lifestyles and characteristics are able to modify the behavior of the individual as well as reduce emergency room visits and hospitalizations. Thus, it is necessary to develop this study.

This study is a controlled clinical trial. The intervention will be a curriculum intervention on asthma. This intervention will consist of theoretical - practical weekly workshops with a targeted content for asthma and involves aspects related to anatomy and physiology of the respiratory tract, conceptualization of asthma, prevention, treatment, maintenance and retrieval; recognition and actions in periods of exacerbations and use the action plan. These workshops are suitable for the course plan of disciplines sciences, biology, chemistry, physics, history , geography, portuguese and mathematics . Those are characterized as a mandatory curriculum component and they should be developed for all students in elementary and secondary education.

In parallel curriculum intervention, the investigators will identify the frequency of individuals with diagnosis/symptoms suggestive of asthma by applying the ISAAC questionnaire and verification of Forced Expiratory Volume in one second (FEV1) using the portable Vitalograph copd - 6. This assessment will identify students with suspected asthma, symptoms suggestive of asthma and asthma diagnosed.

The curriculum will be organized educational intervention with school staff to be applied to the intervention group (it includes all students from 10 to 19 years previously registered. The afternoon shift is defined as the intervention group and may participate asthmatic and non-asthmatic students). It is noteworthy that, subsequently, the same intervention will be performed with the control group (in which students participate in the morning shift and may participate in asthmatic and non-asthmatic students). The intervention group will receive a complementary intervention where questions directed reinforce attitudes in periods of exacerbation and use the action plan, while the control group will receive this same intervention after the study.

The study will be held at the College Presidente Emilio Garrastazu Medici (Currently its name is College Estadual do Stiep Carlos Marighella) which is a school unit with medium-sized and offers all series of the second segment of the Elementary School, Middle School and Professional Education. This school was chosen because of system of evaluation and teaching methodology as well defined in its political pedagogical project.

The investigators will identify the frequency of individuals with diagnosis/symptoms suggestive of asthma by applying the ISAAC questionnaire and verification of Forced Expiratory Volume in one second (FEV1) will monitor all individuals duly registered and allocated in the age group 10-19 years are enrolled in the 5th to 8th grades in this study.

A despite about data Collection Instrument, will be used: 1. Questionnaires ISAAC - International Study of Asthma and Allergies in Childhood; 2. Form to characterize the subjects and clinical outcomes and 3. Structured questionnaires for assessing knowledge (two different data collection instruments):

  1. Questionnaires ISAAC - International Study of Asthma and Allergies in Childhood:

    In the first phase of the study, standardized questionnaires developed by ISAAC will be applied. It aims to evaluate symptoms suggestive of asthma. The first part of the questionnaire consists of 8 questions which mainly use 3 questions to estimate the prevalence of asthma : 1 - " Did you ever in your life you (or your child ) had wheezing (wheezing )? " , 2 - "In the last twelve months you (or your child ) had wheezing ( wheezing )?" 3 - "Have you ( or your child ) had asthma?".

  2. Form to characterize the subjects and clinical outcomes:

    This form is composed of two parts: the first part consists of demographic and socio biological data and the second parts of issues related to clinical outcomes. The variables are emergency due to asthma in the past year, emergency due to asthma in past 30 days, emergency due to asthma past two weeks, prior oral intubation, hospitalization due to asthma in the last year, ICU admissions, nocturnal awakenings in the last year, nocturnal awakenings in the last 30 days, nighttime awakenings in the last two weeks, daytime last year awakenings, daytime awakenings in the last 30 days, daytime awakenings in the last two weeks, number of days missed at school in the last year, number of days missed at school last month, number of lost subjects (if already deprecated) in the last year, use of control medications, spirometric values. This form must be applied before and after implementation of the intervention.

  3. Form for assessing knowledge:

To assess knowledge about asthma and the exacerbation due to this disease, a structured questionnaire that contains 20 questions with three possible answers to all questions will be used: "Yes", "no" and " I do not know". This questionnaire is organized so that a number of questions covering a field but it is not built for the explicit subject in the research.

The areas are: knowledge of the pathology, triggers, treatment, management of crisis and myths/truths so that the researcher can analyze the performance counting the overall score and domains.The adjustments represent the knowledge level of the respondent. Up to 25 % of hits - Poor knowledge; 26 - 50% correct - satisfactory knowledge; 51-75 % accuracy - Good knowledge; 76-100 % correct - excellent knowledge.

Knowledge about learning about relief treatment and maintenance will be carried out through a questionnaire consists of 4 situations that mimic reality. It trys to observe the therapeutic knowledge of the individual in situations of imminent asthma attack , with the following options answer: "never", "rarely", "sometimes" , "often" ,"always".

The investigators will collect data and analyzed in the period from October 2011 to December 2014. Tools of data collection described above and after signing the Informed Consent and the Coordinator of School and after approval of the research by the Ethics Committee - Universidade Federal da Bahia. This protocol was submitted and approved.

The investigators will use the Statistical Programme Statistic Program for Social Sciences (SPSS) version 21.0 to process data. We will analyse data by descriptive statistics (proportions and measures of central tendency), Relative risk (RR) , absolute risk (AR) , odds ratios (OR) and logistic regression analysis to identify the measures of association will be used effect of systematic educational interventions independent of confounding variables. In all analyzes will be considered the significance level of 5 % .

The ethical aspects shall be based on Resolution 196/96 governing research involving human subjects, the resolution 466/2012 and the Code of Ethics for Professional Nursing. The research will respect the basic principles of bioethics: autonomy, non - maleficence, beneficence, and justice, and should be appropriate to scientific principles, rely on free and informed consent of the research subject and / or his legal representative, establish procedures to ensure confidentiality and privacy of the people involved indirectly. The Program will receive the return of the results obtained through research.
