Patients’ Cognitive Status and Its Related Factors Before Coronary Artery Bypasses Grafting

Cognitive status of patients before Coronary Artery Bypass Grafting (CABG) affects their activities of daily living. Evaluation of cognition status and its related factors can help caregivers to plan suitable care programs.

This study aimed to evaluate the patient’s cognition status and its related factors before CABG.

This cross-sectional study was done in 2016 on 139 patients before CABG who were selected by convenience sampling method. The study data were collected by Cognition Failure Questionnaire (CFQ), Hospital Anxiety and Depression Scale (HADS), and a sociodemographic questionnaire. CFQ scores range from 0-100, and higher score shows the weaker status of cognition. The obtained data were analyzed by descriptive and inferential statistics of the Man-Whitney U test, the Chi-squared test, and logistic regression.

The Mean±SD score of cognitive status of the samples was 12.92±12.73. The findings showed significant relationship between cognitive status and age (P=0.002) and anxiety (P<0.05). The results of logistic regression showed that age (P=0.020, OR =1.070, 95%CI=1.011-1.133), moderate anxiety (P=0.007, OR =6.067, 95%CI=1.62-22.60), and case of anxiety (P=0.001, OR=14.331, 95%CI=2.82-72.72) are the patients’ cognitive status predictors before CABG.

Based on the findings, age and preoperative anxiety are related to the cognitive status before CABG. These variables should be emphasized in preoperative nursing care in cardiac surgery wards.
