Background: It is widely recognized that patients have increased anxiety before elective surgery, however, previous research investigating the effect of preassessment clinics (PACs) on anxiety levels has been limited specifically to patient information literature or multimedia use, rather than the consultation process itself. The aim was to investigate the effect attendance at PAC had on patients' anxiety levels, associated with their subsequent surgery and anesthetic.
Materials and Methods: This survey consisted of a cross-sectional, questionnaire-based, quantitative study investigating patients' anxiety levels before and after attendance at the PAC. The questionnaire consisted of a series of statements concerning the surgery and anesthetic and rated using a Likert-type scale. All adult patients who attended an appointment at the PAC were eligible to participate in the study. Those unable to read and understand the questionnaire were excluded.
Results: Overall 121 participants were included in the study. Participants felt less anxious about their subsequent surgery and anesthetic following consultation at the PAC (P < 0.001). This was true for both gender subgroups (P < 0.05) Concerns about intraoperative complications generated the most anxiety. Postoperatively, male participants were most anxious about pain and females about nausea and vomiting. Participants also reported high satisfaction rates for the service at the PAC.
Conclusions: This study contributes to a greater understanding of preoperative anxiety and has important implications for PACs. This clinical survey has been able to demonstrate that consultation at the PAC has a statistically significant positive effect on alleviating patients' anxieties in regards to their surgery and anesthetic.
