Intervention can improve medication adherence during intervention period (MD 10.9; 95%CI 5.0 to 16.7). The benefit probably requires constant intervention because the effect dissipated in the postintervention period (MD 3.9; 95%CI -2.8 to 10.7). The intervention can reduce the number of all-cause readmission to the hospital or emergency department and slightly reduces mortality. |
