Heart failure (HF) is a complex, multifactorial syndrome resulting from impaired heart function. The estimated prevalence of heart failure (HF) in India is approximately 1% of the Population or about 810 million people and the estimated mortality from heart failure is about 0.10 to 0.16 million people per year. A randomised controlled trial is proposed to examine the nurse led mHealth and module-based educational intervention on self-care behaviour, clinical outcomes and quality of life among heart failure patients. The expected results of the nurse led mHealth and module-based educational intervention would help the heart failure patients to be knowledgeable about their disease, acquire skills needed to monitor and recognize their symptoms and perform adequate self-care. All study participants will receive usual care, which includes all medical, nursing, allied health, and follow-up services provided by the study hospital. After obtaining the participants informed consent the researcher will collect the baseline data. It will include the sociodemographic variables, clinical profile, clinical outcomes, Self-Care of heart failure index (SCHFI), Cardiac self-efficacy scale (CSES), Health related quality of life (HRQoL-Minnesota living with heart failure questionnaire), Symptoms status question heart failure (SSQHF), Medication adherence rating scale. The researcher will contact the participants and arrange appointments to collect post intervention data at 3 months from baseline (T1), and 6 months from baseline (T2). The collected data will be analyzed using descriptive and inferential statistics with software like SPSS 20 and Microsoft Excel, and the results will be presented in the form of tables, graphs, and figures. Findings of the study will be disseminated.
