An Easy and Reliable Way to Prevent Electrocardiographic Deteriorations of Patients Undergoing Off-Pump Coronary Artery Bypass Surgery: Preoperative Anxiolytic Treatment

The Effect of Health Literacy on Preoperative Anxiety Levels in Patients Undergoing Elective Surgery

Objective

This study aimed to determine preoperative anxiety levels, their associated factors, and the relationship between health literacy and preoperative anxiety in adult patients undergoing elective surgery.

Materials and Methods

This descriptive cross-sectional study was conducted in a tertiary hospital between December 21, 2021, and June 20, 2022, and included 466 adult patients. Participants were administered the demographic data and basic health status form, Health Literacy Scale (HLS), and Beck Anxiety Inventory (BAI). Statistical significance was set at p < 0.05.

Results

The participants' mean BAI score was low to moderate (9.28±10.85). The total HLS score was 105.89±24.42. For the BAI, a negative correlation was found between the access to information sub-dimensions of the HLS and BAI (p=0.043, r=-0.094). In addition, a negative correlation was detected between patients' age and HLS and its sub-dimensions (p<0.001, respectively [r=-0.188, r=-0.193, r=-0.205, r=-0.161]), and a positive correlation was observed among the HLS sub-dimensions (p<0.001, respectively [r=0.873, r=0.057, r=0.966, r=0.915]). Higher HLS and sub-dimension averages were observed in single, high school, university graduates, and civil servant participants. In addition, higher BAI averages were detected in females, homemakers, urban residents, participants living only with their children, and those with additional diseases (respectively, p<0.001, p<0.001, p=0.007, p=0.0034, p<0.01).

Conclusion

As the level of health literacy increased, preoperative anxiety levels decreased. Preoperative assessment and education are fundamental to perioperative patient care, particularly in the surgical setting.

Relationship between preoperative anxiety and onset of delirium after cardiovascular surgery in elderly patients: focus on personality and coping process

BACKGROUND

Postoperative delirium is associated with increased mortality. Therefore, it is important to manage delirium during the entire perioperative period. Preoperative anxiety is associated with poor prognosis in postoperative patients who have undergone cardiovascular surgery. This study aims to investigate the relationship between preoperative anxiety and onset of delirium after cardiovascular surgery in elderly patients (aged 65 years or older), considering the individual psychological characteristics, such as personality and stress coping skills in response to anxiety, as confounding factors.

METHODS

This prospective study included patients aged >65 years in a preoperative state before undergoing cardiovascular surgery. Subjects were divided into two groups based on whether they experienced postoperative delirium, or not. We compared clinical and demographic factors, preoperative psychiatric and psychological factors, and intraoperative and perioperative physical factors between the control and delirium groups. Multiple imputations were used to account for missing data.

RESULTS

Out of 168 subjects enrolled in this study, 26 (15.5%) developed postoperative delirium. Univariate analysis showed significant differences in age (P = 0.027), cognitive function (P = 0.007), agreeableness (P = 0.029), and the Acute Physiology and Chronic Health Evaluation-II (APACHE-II) score (P = 0.023) between the delirium and control groups. Multiple logistic regression analysis did not identify a significant association between preoperative anxiety and the onset of postoperative delirium. However, age (odds ratio (OR) = 1.114, P = 0.018), agreeableness (OR = 0.555, P = 0.008), and the APACHE-II score (OR = 1.227, P = 0.008) were identified as risk factors for postoperative delirium.

CONCLUSION

Agreeableness, one of the personality traits associated with preoperative anxiety, appears to be involved in the development of postoperative delirium as an independent psychological factor, regardless of age or physical factors.
