Preoperative stress and anxiety in day-care patients and inpatients undergoing fast-track surgery.

BACKGROUND

To investigate preoperative levels of stress and anxiety in day-care patients and inpatients undergoing surgical interventions.

METHODS

Before induction of anaesthesia, the degree of stress and anxiety was assessed in 135 patients using stress and anxiety questionnaires, bio-feedback, physiological measures, and serum levels for stress variables. Questionnaire responses and physiological measures such as arterial pressure, heart rate, skin conductance, cortisol, and catecholamine levels were compared for day-care patients and inpatients.

RESULTS

Significant preoperative anxiety was reported by 34 (45.3%) inpatients and 23 (38.3%) day-care patients. Personal responses in stress and anxiety questionnaires and mean values of arterial pressure and heart rate did not differ significantly in day-care patients when compared with inpatients. Correlation between deviations in plasma cortisol concentrations from normal diurnal distribution and anxiety scores and stress scores was also similar, and the relative increase in preoperative stress variables and measures observed in day-care patients and inpatients was also comparable. Bio-feedback measurements revealed significantly higher preoperative skin conductance (P<0.001) in day-care patients than in inpatients, indicating increased vegetative stress responses.

CONCLUSIONS

Preoperative anxiety and stress are common in surgical patients. Questionnaires and bio-feedback measurements may help to assess the degree of patients' burdens. Surgeons should be aware of the personal anxiety of patients and consider patient preferences when deciding who should undergo fast-track surgery in day-care.
