After the hospital discharge, the intervention group will receive the telephone follow-up (five calls for six months: 1st call in one week and the others calls month by month until six months) and two face to face counseling (1st meeting in three months and the 2nd meeting in six months). The control group just receive the same face to face counseling (1st meeting in three months and the 2nd meeting in six months) after the hospital discharge.
