ABSTRACT
<p><b>INTRODUCTION</b>Knowing how patients value the quality of anaesthesia helps anaesthesiologists to customise their service. However, generalising findings from Western population-based willingness-to-pay studies across different cultures and societies might result in the oversight of some contextualised perspectives of the anaesthesia experience. This study aimed to capture the Singapore perspective of undesired post-anaesthesia outcomes.</p><p><b>METHODS</b>132 patients recruited in a pre-anaesthetic evaluation clinic were given questionnaires describing ten possible post-anaesthetic outcomes. Outcomes were ranked for undesirability and assigned relative value through the hypothetical proportioning of SGD 100 to avoid their occurrence. Data was analysed with reference to patients' background and anaesthetic history.</p><p><b>RESULTS</b>A response rate of 69.1% (n = 132/191) was achieved. Outcomes from the most to least undesirable were pain; vomiting; nausea; shivering; orodental trauma; sore throat; abrasions; somnolence; and thirst. Relative values allocated, in descending order, were pain; vomiting; nausea; orodental trauma; abrasions; sore throat; shivering; somnolence; and thirst.</p><p><b>CONCLUSION</b>Similar to previous studies in Western populations, pain, vomiting and nausea were the top three adverse outcomes that Singapore patients wished to avoid. However, discrepancies with Western patients were seen in spending attitudes, possibly accounted for by differences in healthcare socioeconomics. This study provided a better understanding of Singapore patients' perspectives on post-anaesthesia adverse outcomes and could help to improve treatment strategy and resource management.</p>
