Evaluation of the effectiveness of a nursing intervention aiming at facilitating the hospital to home transition within a cardiologic Emergency Room (ER) [Évaluation de l’efficacité d’un modèle d’interventions infirmières de soutien à la transition hôpital-domicile dans une urgence cardiologique]

'Return to ER: the occurrence of any visits to the cardiologic ER in the month following randomisation. This will be measured using the hospital patient's registry.

The secondary outcomes will be measured at baseline and one month following randomisation by a telephone interview and are as followed:
1. Health care continuity using the Heart Continuity of Care Questionnaire (HCCQ), a 41-item questionnaire using a 5 points Likert scale (score 1 to 5, 1 = strongly disagree, 5 = strongly agree) measuring the patients' perception of continuity of care in regard to eight different dimensions. A higher score indicate a better continuity of care process according to the patient.
2. Patient's self-care management using the Therapeutic Self-Care Tool (TSCT), a 12-item questionnaire using a 5 points Likert scale (score 0 to 5, 0 = not at all, 5 = very much so) measuring the patients' ability to initiate and perform activities aiming at maintaining health, managing health problems and restoring functioning. A higher score indicate better self-care capacities in the patient.
3. Medication adherence scale using the Self-Reported Medication-Taking Scale (SR-MTS), a 4-item questionnaire using a dichotomous (yes or no) scale measuring patients' adherence to prescribed medication. A higher score indicate a poorer adherence to medication.
4. Patients' perception of control over the disease and of its consequences using three subscales of the Illness Perception Questionnaire - Revised (IPQ-R), a 38-item questionnaire using a 5 points Likert scale (score 1 to 5, 1 = totally agree, 5 = totally disagree) measuring the patients' perception of his disease. The three subscales used are:
4.1. Consequences (6 items)
4.2. Personal control (6 items)
4.3. Treatment control (5 items)
Higher scores on the consequences subscale represent strongly held beliefs about the negative consequences of the disease. Higher scores on the control subscales represent positive beliefs about the controllability of the illness.
5. Anxiety and depressing feelings using the Hospital Anxiety and Depression Scale (HADS), a 14-item questionnaire using a 4 points ordinal rating scale and composed of two subscales (anxiety and depression - each score from 0 to 21). A higher score to each of the subscales indicate a higher degree of symptoms (anxiety or depression).
6. Health services utilisation using the medicare provincial registry (Régie de l’assurance maladie du Québec). The occurence of ER visits, hospitalisation or medical consultations by the patient within the province of Québec will be collected at 1, 3, 6 and 12 months following discharge.
