Objective: to evaluate the efficacy of an mHealth intervention, with respect to routine clinical practice, to improve health literacy and self-management of the multiple pathological patient with heart failure and complex health needs.~Hypothesis: the proposed mHealth intervention is more effective than usual clinical practice, favoring health literacy and self-management of multiple pathological patients with heart failure and complex health needs, so its use would be relevant as part of the assistance process.~Methodology: randomized, controlled, multicenter clinical trial for the evaluation of the efficacy of an mHealth intervention with two groups: a control group (routine clinical practice) and an experimental group (routine clinical practice together with ad hoc designed mHealth intervention).~In this project, the design and content validation of the mHealth tool will be carried out, evaluating its relevance and suitability.
Multipathological patients with complex health needs are responsible for the majority number of avoidable hospital admissions.~The expansion of mHealth interventions in the field of communication with the patient, the reduction of health inequalities, the improvement in access to health resources, the adherence to treatments and self-care of chronic diseases lead to an optimistic horizon . However, there are few applications that demonstrate its effectiveness in these patients, which is diminished when they are not based on evidence, nor are designed by and for users with different levels of health literacy.
