Patient-reported perioperative anaesthesia-related anxiety is associated with impaired patient satisfaction: a secondary analysis from a prospective observational study in Switzerland.

Perioperative anxiety is common. The relationship between anxiety and patient satisfaction with anaesthesia is still under debate. We assessed the prevalence and different causes of anaesthesia-related fears leading to perioperative anxiety and its association with patient satisfaction. A multiple-time validated, psychometrically developed questionnaire assessing the presence of anxiety, causes of fear, and different dimensions of patient satisfaction was sent to patients after discharge. The clinical data were obtained from a previous study. The sample size was calculated to recruit a minimum of 300 completed questionnaires. Statistical analyses included multivariate logistic regression models. Complete data were available for 474 of the 600 patients recruited for the study (response rate: 79%). A total of 141 patients (30%) reported anxiety regarding anaesthesia before hospital admission. The prevalence of anxiety was significantly associated with patient age (< 54 years: n = 196, prevalence = 37%; > 54 years: n = 263, prevalence = 24%; p = 0.002), female sex (female: n = 242, prevalence 39%; male: n = 223, prevalence 20%; p < 0.001), and surgical speciality (gynaecology (n = 61, prevalence = 49%), otolaryngology (n = 56, prevalence = 46%); p < 0.001). Fear of not awakening from anaesthesia (n = 44, prevalence = 32%, SD 45.8) and developing postoperative nausea or vomiting (n = 42, prevalence = 30%, SD 46.0) were the most reported anaesthesia-related causes of fear. Anxiety was associated with impaired overall patient satisfaction (mean dissatisfaction score 15%, versus 23%, SD 16.3 in the anxious group, SD 16.3, p < 0.001), especially regarding the dimensions "information and involvement in decision-making" (14% of deficits stated in the non-anxious group compared to 23% in the anxious group, p < 0.001), "respect and trust" (2% vs 6.26%, p < 0.001) and "continuity of care" (50% vs 57%, p < 0.015). Patient-reported anaesthesia-related anxiety is common and may affect important outcome parameters such as patient satisfaction.
