INTRODUCTION: Postoperative nausea and vomiting (PONV), and postoperative pain are common during the early postoperative period. In addition to these problems, elderly patients risk developing postoperative confusion. This study aimed to identify the risk factors associated with these problems, and the extent of these problems, in a Singapore inpatient surgical population. METHODS: Over a period of six weeks, we surveyed 707 elective surgical inpatients aged ≥ 18 years who received general anaesthesia and/or regional anaesthesia. RESULTS: The incidence of PONV was 31.8% (95% confidence interval [CI] 34.8-41.9). The incidence increased with increasing Apfel score (p < 0.001) and were higher in female patients (odds ratio [OR] 1.74, 95% CI 1.28-2.36), non-smokers (OR 1.72, 95% CI 1.04-2.88), patients with a history of PONV and/or motion sickness (OR 3.45, 95% CI 2.38-5.24), patients who received opioids (OR 1.39, 95% CI 1.03-1.88), and patients who received general anaesthesia (OR 1.76, 95% CI 1.11-2.79). Moderate to severe pain at rest and with movement were reported in 19.9% and 52.5% of patients, respectively. Among the patients who were predicted to experience mild pain, 29.5% reported moderate pain and 8.1% reported severe pain. The prevalence of postoperative confusion was 3.9% in the geriatric population. CONCLUSION: Higher Apfel scores were associated with a higher risk of PONV and multimodal treatment for postoperative pain management was found to be insufficient. The incidence of postoperative confusion was low in this study.
