Abstract

In a study of 429 elderly patients, mean preoperative perceived stress was 12.77 ± 5.41 and increased to 13.39 ± 5.26 postoperatively.

Higher levels of neuroticism, depression, and body mass index (BMI) were significant predictors of preoperative perceived stress.
Preoperative perceived stress was the only factor significantly associated with postoperative perceived stress.
Preoperative perceived stress was linked to an increased risk of postoperative delirium in the recovery room (odds ratio = 1.181).
Cognitive function, assessed by the Montreal Cognitive Assessment (MoCA), was identified as a predictor of overall postoperative delirium (odds ratio = 0.864).
Assessing and addressing preoperative perceived stress may help reduce the risk of postoperative delirium.

This study examined levels of perceived stress (PS), postoperative delirium (POD) and associated factors among Thai elderly patients undergoing elective noncardiac surgery.Preoperative PS and change after operation have not been widely studied. Moreover, psychological factors associated with PS and POD has been poorly investigated.In total, 429 elderly patients were recruited at a university hospital. The preoperative evaluation included sociodemographic data, health behaviors at risk, Perceived Stress Scale (PSS-10), Neuroticism Inventory (NI), Mental State Examination T10 (MSET10), Montreal Cognitive Assessment (MoCA) and Geriatric Depression Scale (GDS-15). Three-day postoperative evaluation included PSS-10 and Confusion Assessment Method Algorithm (CAM) or CAM-ICU for Delirium. Multiple regression and logistic regression analysis were performed to determine potential predictors.Females were 58.97%, and the mean age was 69.93 ± 6.87 years. Mean pre- and postoperative PS were 12.77 ± 5.41 and 13.39 ± 5.26, respectively (< 0.05). Multiple regression revealed that neuroticism, depression, and BMI predicted PS significantly. None of the independent variables was found to predict postoperative PS except for preoperative PS (<.001). POD at the recovery room was predicted by preoperative PS (odds ratio = 1.181, 95% CI = 1.019-1.369), whereas overall POD was predicted by MoCA (odds ratio = .864, 95% CI = .771 -.968).Preoperative PS was significant in that it was associated with postoperative PS and POD. A careful assessment of preoperative PS as well as providing brief interventions for patients with high levels of this condition may reduce the risk of POD.
