Factors associated with preoperative anxiety levels of Turkish surgical patients: from a single center in Ankara

BACKGROUND Preoperative anxiety and stress are undoubtedly a difficult experience in patients undergoing elective surgery. These unpleasant sensations depend on several factors. The objective of this study was to evaluate the preoperative anxiety levels in a sample of Turkish population, as well as the underlying causes using the Spielberger State-Trait Anxiety Inventory (STAI anxiety) scale. METHODS The study was conducted according to the Declaration of Helsinki and was approved by the local ethical committee. All participants gave written informed consent upon having received detailed information on the study. Upon entry in the study, state and trait anxiety questionnaires were completed by 186 patients scheduled for elective surgery. The influencing factors in regard to age, sex, educational status and others were also reported. RESULTS There was a statistically significant positive correlation between state and trait anxiety scores in this Turkish population. While the most important predictive factors that affected state-STAI scores were age, sex and duration of sleep the night before surgery; educational status and age were the best predictors for determining the variation in trait-STAI scores. CONCLUSION The factors affecting anxiety levels in different populations might vary among different countries. Interestingly, in this sample of Turkish population, the trait anxiety levels were found to be higher from state-anxiety levels, especially in women and less educated people. Thus, doubts about operation and anesthesia are overlooked. This could be attributed to the low to intermediate life standards of people admitted to our hospital.
