A randomized parallel single-center clinical trial, blinded for the evaluation of the outcomes and statistical analysis. The current hypothesis is that PEAC-IC will improve self-care behavior, knowledge about heart failure, health-related quality of life, and the number of hospitalizations and searches for emergency services in the participants with heart failure.
Heart failure (HF) is an insidious chronic syndrome that impacts the quality of life of people affected by it. One of the ways of controlling the progression of the syndrome is self-care, which involves behaviors to maintain health and to monitor and manage the symptoms of the disease. Several studies have shown that when the person with HF has adequate self-care, there is a reduction in the rate of morbidity and mortality, hospital readmissions, and an improvement in the quality of life. Despite the benefits of self-care, it is still deficient among people with HF in Brazil and worldwide. To improve self-care, educational interventions for the development of skills and behaviors must be performed by nurses, due to their role concerning health education. The Programa Educativo para o Autocuidado na Insuficiência Cardíaca - PEAC-IC is an intervention created to promote the achievement of positive results for people with HF. In a pilot study, PEAC-IC was assessed for acceptability and feasibility, with satisfactory preliminary results. Main objective: To compare the effect of the PEAC-IC with the usual care on self-care behavior, on knowledge about heart failure, on health-related quality of life, and on the number of hospitalizations and searches for emergency services due to HF. Method: This is a randomized parallel single-center clinical trial, blinded for the evaluation of the outcomes and statistical analysis. Participants (1. adults and elderly hospitalized for HF, adults and elderly with HF follow in outpatient care) who meet the participation criteria will be randomized in a simple random way between the intervention and control groups. The intervention group will receive the usual care and the PEAC-IC, offered in one face-to-face session and five structured telephone contacts. The control group will receive only the usual care, which consists of guidance during hospital discharge and delivery of a discharge planning form and outpatient follow-up with medical and nursing consultations and exams when indicated. Both groups will have the outcome variables assessed at baseline, in the seventh week, in the third and sixth months after allocation in the trial. This study will be carried out at the Clinical Cardiological Unit with 42 active beds and a cardiomyopathy outpatient clinic that offer a multidisciplinary health care of approximately 70 clinically stable patients with HF of the Instituto Dante Pazzanese de Cardiologia (IDPC), a public teaching hospital specializing in cardiovascular care. The research will be appreciated by the Research Ethics Committee and will only start after a favorable opinion at the University of São Paulo School of Nursing and the hospital.

Change in Self-care behavior
Self-care behavior will be assessed by the Brazilian version of the Self-Care of Heart Failure Index v.6.2 (SCHFI), the Self-Care Scale for Patients with Heart Failure, adapted and validated for use in Brazil. This scale consists of 22 items divided into three subscales. The scores for each subscale can range from 0 to 100 points, and scores equal to or greater than 70, in any subscale, reflect adequate self-care.
Time frame: Self-Care of Heart Failure Index v.6.2 will be assessed at the - T1: research participant allocation, T2: seven weeks after allocation, 3 months after T2 and 6 months after T2.
Change in Knowledge on Heart Failure
The "Disease Knowledge Questionnaire will assess knowledge on Heart failure for Patients with Heart Failure", created and validated for use in Brazil. It consists of 19 items: the HF pathophysiology contents, its concept, diagnosis, risk factors, symptoms, lifestyle habits, treatment, medications used, self-care, and physical exercise. For each item, there are four alternatives: one is the correct answer; one is incomplete; one is incorrect and one is "I don't know". According to the total score obtained, can be categorized as excellent (51 to 57 points); good (40 to 50 points); acceptable (29 to 39 points); little knowledge (17 to 28 points) and insufficient knowledge (\< 17 points).
Time frame: Disease Knowledge Questionnaire will be assessed at the - T1: research participant allocation, T2: seven weeks after allocation, 3 months after T2 and 6 months after T2.
Change in quality of Life
Quality of Life will be asses using the Minnesota Living with Heart Failure Questionnaire, the validated Portuguese version. The instrument consists of 21 items that assess the participants' perception regarding how much the signs and symptoms of HF made it impossible/limited the daily activities or the activities that the participants would like to perform/perform. These items refer to the physical, emotional and socioeconomic aspects that the presence of HF can impact and the answers range from zero to five points (0: nothing; 1: very little to 5: too much). The final score is obtained through the sum of the answers of the 21 items and can range from zero to 105 points, the higher the score, the worse the quality of life and the lower the score, the better quality of life.

Time frame: Health-related Quality of Life will be assessed at the - T1: research participant allocation, T2: seven weeks after allocation, 3 months after T2 and 6 months after T2.
Change in search for emergency medical care due to clinical decompensation of Heart Failure
Number of times reported by the participant or family member/caregiver of fearch for emergency medical care due to clinical decompensation of Heart Failure
Time frame: Will be assessed at the - T1: research participant allocation (number of times during the last 12 months), T2: seven weeks after allocation, 3 months after T2 and 6 months after T2.
Change in hospitalization due to clinical decompensation of Heart Failure
Number of times reported by the participant or family member/caregiver of hospitalization due to clinical decompensation of Heart Failure
Time frame: Will be assessed at the - T1: research participant allocation (number of times during the last 12 months), T2: seven weeks after allocation, 3 months after T2 and 6 months after T2.
Change in feeling of Powerlessness
The feeling of powerlessness will be assessed by the Powerlessness assessment tool, created and validated in adults in the process of hospitalization. It consists of 12 items divided into three domains: the ability to perform a behavior, perception of the ability to make decisions and emotional response to control situations. The possibilities of answering the 12 items range from 'never to 'always' scored from 1 to 5. A cutoff score is not provided for interpreting the results. However, the higher the score, the more intense the feeling of impotence. The score obtained through this instrument will be treated as a continuous quantitative variable, for further categorization under the guidance of a statistician.
Time frame: Will be assessed at the - T1: research participant allocation (number of times during the last 12 months), T2: seven weeks after allocation, 3 months after T2 and 6 months after T2.
Change in Depressive symptoms
The Depressive symptoms will be assessed by the Depression Scale CES-D (Center for Epidemiologic Studies Depression Scale) which aims to identify depressive mood and a possible vulnerability to depression. This instrument was created by the NIMH - National Institute of Mental Health and consists of 20 items that measure the occurrence of depressive symptoms, such as mood, somatic symptoms, interactions with other people, and motor functioning, from the frequency of symptoms in the last week to interview. The score for the 20 items can range from 0 to 3 and the response options range from rarely or never, a few times, sometimes, almost always, or always. Thus, the total score varies between zero and sixty points. The occurrence of depressive symptoms is considered from a score of ≥ 16 points
Time frame: Will be assessed at the - T1: research participant allocation (number of times during the last 12 months), T2: seven weeks after allocation, 3 months after T2 and 6 months after T2.
