Telematic Educational Intervention in Patients With Heart Failure.

Background: Heart Failure (HF) is one of the most prevalent pathologies in Western countries, representing a significant percentage of their healthcare expenditure. Much of the success of specialised programmes for the control and treatment of this pathology is achieved within Heart Failure Units. These programmes are based on enhancing patients' capacity to perform effective self-care. Self-care in heart failure involves several aspects: maintaining healthy lifestyle habits, monitoring signs and symptoms of decompensation, controlling blood pressure, heart rate, and body weight, and the ability to manage potential decompensations either autonomously or by seeking available healthcare services. Heart failure units carry out structured therapeutic education for these patients through individualized, face-to-face educational interventions upon admission to the unit, placing special emphasis on training patients and their caregivers in effective self-care. However, studies show that the level of self-care among HF patients remains low. Furthermore, the new healthcare reality following the pandemic situation necessitates the search for strategies that facilitate better time management while improving the self-care capacity of HF patients. Within this clinical context, it is necessary to seek alternatives that allow for the provision of adequate quality of care while overcoming the obstacles imposed by the current situation. Objective: The objective of the study is to evaluate the effectiveness of a telematics-based educational intervention, in addition to the standard standardised educational intervention, in self-care in patients in the Heart Failure Unit six months after admission. Methodology: A randomised clinical trial design with parallel groups (intervention and control) will be applied. The study sample, consisting of 50 patients in each group, will be recruited from patients treated in the Heart Failure Unit of the University Hospital. All patients and their
