The effect of a family-based participatory care program on anxiety in patients with acute coronary syndrome in coronary care units: A randomised controlled clinical trial.

BACKGROUND: Admission to the coronary care units (CCUs) and the patient's reduced interaction with family are regarded as important sources of anxiety. Family participation in care programs is pivotal to patient outcomes.

OBJECTIVES: The present study was conducted to determine the effect of a care program based on family participation on anxiety in patients with acute coronary syndrome.

METHODS: This randomised controlled trial was conducted on 90 patients in CCUs and their families. The patients were randomly assigned to one of the following three groups: routine care, control, and intervention. Routine care measures were provided to the routine care group, increased participation of the family was ensured in the control group, and a family-based participatory care program was implemented in the intervention group with the interaction of the nurse, patient, and family based on five principles, including presence, determination of needs, communication, participation in decision-making, and cooperation in care. The patients' anxiety was measured in the three groups on day 1 and 3 days after the admission to the CCU using the Spielberger State-Trait Anxiety Inventory.

RESULTS: The patients' mean state anxiety score before the intervention was 44.4 ± 12.7, 46.6 ± 12.4, and 45.5 ± 12.1 in the routine care, control, and intervention groups, respectively, with no significant differences between them (P = 0.81). After adjusting for anxiety before the intervention and study hospital, the mean (before-after) changes in anxiety score in the three groups showed that anxiety was significantly lower in the intervention group than in the other groups (P < 0.05).

CONCLUSION: Increased family presence alone has no effect on the patients' anxiety, but the family's participation and interaction with the care team can affect anxiety levels in cardiac patients in CCUs and improve the care processes.
