A comprehensive geriatric assessment was performed during the first admission in all patients. Patients were randomly allocated to a nursing intervention group or a usual care group. In patients from the intervention group, a nursing intervention programme was performed 3 months after admission, based on education, support and patient monitoring to improve therapeutic adherence and a 6 month phone call. The main outcome measured was therapeutic adherence at 12 months, as defined by a combination of adherence measurement tools (Morisky-Green and Hayness-Sacket scales, attendance at visits and withdrawal of medication from the pharmacy). Therapeutic adherence was assessed by nurses blinded to the assignment group.
The objective of this study was to assess the impact of a nursing intervention on therapeutic adherence in elderly patients after acute myocardial infarction compared to a control group
