Improving Knowledge in Heart Failure Inpatient With Therapeutic Education

Beliefs about medicines will be measured via the specific Beliefs about Medicines Questionnaire (BMQs) score at baseline time (at the inclusion time)(pretest) and at 1 month after hospital discharge (post-test) in both groups.

Scores range from 5 to 25 points for both subscales. The higher the score for the specific need, the more it means that the patient has a strong perception that he needs the drugs to be healthy and live. For specific concerns, the higher the score, the more the patient is concerned about a potential negative effect of taking the medication. A third score can be calculated by subtracting specific concerns from specific needs. This gives a score of -20 to +20. A positive value means that the need for the treatment exceeds the concerns of taking it.

Adherence will be assessed with the Three Item Self Report Scale at baseline time (at the inclusion time) (pre-test) and at 1 month after hospital discharge (post-test) in both groups.

This questionnaire consists of 3 questions; one which evaluates the number of days of forgetting to take medication over the last month, one which evaluates the frequency of taking medication according to medical prescription and the third which makes it possible to measure the level of competence in the correct taking of medication that takes ownership of the patient. Responses are converted on a scale of 0 to 100 (0 is the lowest adherence and 100 the highest). An average of the three answers is used to assign the adhesion score. Higher the score is, better the adherence is.

Patient satisfaction will be assessed using a 13-questions questionnaire specifically developed for this project, after the education interview to assess the usefulness and quality of the teaching intervention. There is no score related to the questionnaire.

This qualitative assessment will allow us to determine whether this new intervention should be continued and to identify its strengths and weaknesses.

The rate of rehospitalization or emergency room visits will be evaluated during the telephone call made by a research assistant at D30 post hospital discharge. The cause of hospitalization will be determined by means of the computerized hospital patient file if he is rehospitalized at the university hospital of Geneva (HUG) or directly to the patient (or his attending physician depending) if he is hospitalized in another hospital. It is interesting to assess whether the patient consumed unplanned care and whether it was related to instability of his heart failure.

The mortality rate will be assessed in both groups. This information can be collected from the participants' computerized patient records if mentioned or from the participants' relatives or attending physician.

The patient's experience and feelings upon returning home will be assessed during a telephone call between D3 and D7 after the patient's discharge from the hospital with open questions (no validated questionnaire is used). The objective will be to identify the patient's needs, their feelings about going home, what they liked, what they missed to readjust the counseling to the patient.

Use and usability of the mobile smartphone application (CardioMeds® ) will be explored by the research assistant during the telephone call at D30 post hospital discharge using a validated standardized questionnaire (System Usability Scale = SUS).

SUS gives a single score representing a measure composite of the general user-friendliness of the studied service.

The score ranges from 0 to 100.It is generally considered that a score is "good" from 75, fair or fair between 50 and 75. A score below 50 reveals major problems in terms of customer satisfaction.

Self-care skills of patients using CardioMeds® will be explored using a validated score, the Self-Care of Heart Failure Index composed of 22 questions to measure the effect of this application on patients' level of empowerment in their care. The scale is subdivided in three measurement : maintenance score, management score and self-care confidence score. Each scale score is standardized to a 0 to 100 range. A score of ≥70 can be used as the cut-point to judge self-care adequacy,

This second satisfaction questionnaire consisting of 8 questions specifically developed for this project, will be sent at 1 month after hospital discharge to assess the patient's overall satisfaction with the pharmaceutical care follow-up provided. There is no score related to the questionnaire.

This qualitative assessment will allow us to determine whether the hospital pharmaceutical care
