Introduction: Congestive Heart Failure (CHF) significantly affects healthcare use and life quality. Patients need to manage CHF well to maintain a satisfactory quality of life. Self-efficacy (SE) may significantly influence this aspect. CHF is a prevalent cardiovascular problem in both industrialized and developing nations, characterized as a chronic, progressive, and severe condition. This is a prominent behavior change theory that emphasizes the significance of people's SE in their capabilities. SE is the paramount element in Bandura's social cognitive theory, denoting people's belief in their capacity to execute a specific job. Education and training are significantly correlated with an individual's preparedness for the economic transition. This compels several educational stakeholders,including the government, to take action in cultivating talented, knowledgeable, and competitive graduates. Aim of the study: This study sought to estimate the impact of a competency-based learning program on SE in patients with CHF. The purpose was accomplished by the subsequent aims: 1. Evaluate patients' understanding and behaviors related to CHF. 2. Evaluate SE in patients with CHF. 3. Develop and execute a competency based learning program focused on SE for patients with CHF. 4. Assess the impact of a competency based learning program on SE in patients with CHF. Hypothesis This study achieved the following hypothesis: H1: The average knowledge scores of patients after the program application surpass those recorded before to program application. H2: The average practice scores of patients after implementing the program are superior to their results prior to use. H3: Beneficial impact of the implemented program on enhancing patients' SE. Research Design: A quasi-experimental research design was utilized to conduct the study with a pre-posttest was implemented. Study setting: The present study was conducted The outpatient cardiology facilities of Zagazig University Hospitals, located on the first floor, were the site of the investigation. Two classrooms and a waiting area are among the facilities, which also include a stress ECG clinic, a hypertension clinic, a heart rhythm disorder clinic, an ECG clinic, a cardiac disorder clinic, and a cardiothoracic surgery clinic. 1 Study Sample: A purposive sample of 70 patients admitted to outpatient cardiac clinics across six months, diagnosed with any kind of congestive heart failure, who were aware and capable of communication. Patients with severe illnesses, such as cancer and end-stage chronic conditions, as well as those who experienced cardiac arrest, were excluded. Tools for data collection: Three Tools were used for data collection, pertinent to this study as follows: I- The patient interviewing assessment questionnaire II- An observational checklist. III- Chronic Disease Self-Efficacy Scale Tool I: Patient Interviewing Assessment Questionnaire. This tool was composed in straightforward Arabic to prevent misinterpretation; The questionnaire covered three parts as the following: Part I: Socio-demographic questions: A total of 12 queries Through the previous data, the researcher estimated the following: A. Body Mass Index B. Crowding Index= Count of co-residents Part II: patients and Family Past Health History Assessment: This pertains to the evaluation of previous patients and familial medical history. It comprised eight questions as follows: Four closed-ended questions regarding past health history, including the occurrence of congestive heart failure (CHF), its onset, diagnosis, and its correlation with other chronic diseases, as well as four yes-or-no questions concerning smoking, exercise, family history of cardiac disease, and the degree of familial relationship. Part III: Patient’s Knowledge Assessment Regarding CHF: Focused on evaluating patients' understanding of CHF by preand post-tests for the research participants. Tool II: Observational Checklist: It was adjusted by the researcher from an original work by Ahmed et al. (2016) so that it could compare patients' pre- and post-program practices of the most crucial abilities. Tool III: Chronic Disease SE Scale To gauge patients' self-assurance in carrying out certain tasks, the Stanford chronic illness self-management research was created and administered. The evaluation is divided into ten parts and contains 29 items. Pilot study: A pilot study was conducted to evaluate the clarity, comprehensibility, feasibility, applicability, and time efficiency of the tools. Seven patients (10%) from the whole sample population were randomly selected from cardiac units to participate in the tool testing. The patients were incorporated into the trial. No alterations were made to the tools. Field work The study was conducted over six months, commencing in December 2023 and concluding in May 2024, during which the researchers was present 3 days a week from 9 AM to 1 PM. Assessment phase: The researcher started to recruit participants after reviewing their eligibility. Separate interviews were conducted using the data collection form with individuals who gave their consent. 1 Planning phase: The researcher developed a learning program to educate patients on CHF to improve their knowledge, self-management skills, and evaluation results. Implementation phase: The researcher conducted individual meetings with the patients and implemented the foundational learning program across three ten-session intervals, with each session lasting 30 to 45 minutes. Evaluation phase: Every participant in the research had 2 evaluations utilizing identical data-gathering tools. This was conducted at the time of recruiting (pre-test) and after 3 months of instructional learning as a post-test. Results: indicated that most of the investigated patients were male, with 84.2% aged between 53 and 63 years, and 62.8% presenting with comorbidities, mostly hypertension and diabetes mellitus. Statistically substantial enhancements were observed in patients' knowledge, practices, and SE following the intervention period. Conclusion: In light of the current study results, there was a considerable enhancement in patients' knowledge, behaviors, and self-efficacy (SE) following the implementation of the applied learning program compared to the preintervention period. It can be stated that applied based learning positively influenced the increase of SE among patients with CHF by enhancing their knowledge and behaviors. A statistically significant relationship existed between patients' SE and their total scores in knowledge and practice. The current study revealed that fostering personal drive and SE is beneficial. This underscores the significance of a comprehensive patient understanding of their condition. Recommendation: The Based-on findings, the study recommended: -Educational media, including booklets, handouts, movies, posters, and CDs, must be accessible to all patients at all times. -Self-efficacy in patients with CHF should be assessed and included in the treatment plan by a competent nurse. -Consistent monitoring of all individuals with CHF to assess their health status and identify problems promptly.
