Abstract
Aim. The purpose of this study was to review the patient– and family-centered care studies in coronary artery bypass graft surgery.
Background. Nowadays, the length of hospital stay after cardiac surgery is reduced, and the most of the patients recover at home with their families without usual nursing and medical care. It is necessary to provide the care based on the same needs.
Methods. This is a comprehensive review of literature published between 1990-2018 about patient- and family-centered care interventions and patient/family important outcomes in adult ICUs that was conducted through searching out databases and search engines Medline, Ovid, Science Direct, PubMed and Google scholar, including English and Persian papers. In total, 73 English papers and 46 Persian papers were found, out of which 25 papers were included in this review.
Findings. Engaging families in patient care can profoundly influence clinical decision making and patient outcomes. Yet in many hospitals and health care systems, outdated visiting policies separate families and other loved ones during hospital stays.
Conclusion. Patient– and family-centered care is associated with better clinical outcomes. The clinical benefits that have been identified through a family partnership approach in these settings include decreased mortality, increased satisfaction, improved adherence to treatment regimens, and decreased readmission rates. Although high-quality interventional studies are needed to further evaluate the effectiveness of patient- and family-centered care in coronary artery bypass surgery, it is obvious this movement in healthcare is making a huge impact on family satisfaction and patient outcomes.

Abstract
Aim. This study aimed to examine the effects of preoperative preparation of patients and family caregivers on outcomes after coronary artery bypass graft surgery (CABG).
Background. Preoperative preparation can improve patients’ experience of surgery and hospitalization. However, there is limited data about how preoperative preparation affects postoperative outcomes following CABG.
Method. This non-randomized clinical trial was conducted on ninety pairs of patient/ caregiver in the time period from July to November 2018. The participants were purposively selected and non-randomly allocated to either control or experimental group. The intervention was performed one day after admission and the day before CABG in the form of an educational video, an intensive care unit tour, and an educational booklet. In both groups, on the third day after surgery, patients' delirium was assessed in the ICU and family caregivers were asked to complete a family satisfaction questionnaire. Patients and their family caregivers in both groups completed a hospital anxiety and depression questionnaire (HADS) on the first and seventh days after surgery and before discharge. Data were analyzed in SPSS version 16.0 using descriptive and inferential statistics. 
Findings. After intervention, the mean score of patients’ anxiety and depression in the intervention group was significantly less than the control group (P=0.03). After intervention, the mean score of anxiety and depression among family caregivers in the control and experimental groups were not significantly different (P=0.11). Family caregivers’ satisfaction of experimental group was significantly higher than the control group in both healthcare providers’ performance dimension (P=0.01) and comfort dimension (P=0.027). Moreover, the groups did not significantly differ from each other regarding delirium incidence (P=0.6) and length of stay in the intensive care unit (P=0.21).
Conclusion. Considering that the preparation of the patient and family caregiver on the day before CABG can reduce patients' anxiety and depression and increase the satisfaction of the family caregiver, it is recommended to use this intervention for patients and family caregivers before CABG.
