“…In contrast, participants who had undergone surgery in the Netherlands assigned less value to a totally effective analgesic or anti-emetic, with average willingness to pay values of $USD 35 and $USD 17 respectively. Other studies have elicited rankings of the importance of common postoperative side effects (Look, Mok, Tay, & Rizal, 2017;Wagner, Yap, Bradley, & Voepel-Lewis, 2007). In these studies, shivering was ranked as less important to avoid than both pain and nausea and vomiting (Look et al, 2017;Wagner et al, 2007).…”

Forced air warming could be considered cost-effective for procedures performed with sedation in a cardiac catheterisation laboratory if the extra cost of an incremental gain in thermal comfort is less than the decision maker's willingness to pay for it. Therefore, those responsible for decision-making regarding use of FAW in the cardiac catheterisation laboratory can use results of our model to decide if it represents good value for their organisation.

“…The female gender is also the strongest patient-specific predictor for the occurrence of nausea and vomiting associated with anesthesia in human patients (19) and has been shown to have a positive correlation between the respondent and WTP (26). Women in Singapore rank avoidance of nausea as more important compared to men, however, this did not translate into a difference in terms of the patient's WTP (27).…”

“…Human anesthesiologists rank pain, nausea and vomiting as the top low morbidity clinical anesthesia outcomes they believe to be important to avoid (24). Likewise, surveys of human patients consistently rank pain, vomiting and nausea as the top three most undesirable post-operative outcomes (22, 25–27). The desire to avoid nausea and vomiting associated with anesthesia is a universal inclination amongst human beings.…”

“…The desire to avoid nausea and vomiting associated with anesthesia is a universal inclination amongst human beings. Regardless of differences in culture, socioeconomics or healthcare structure, patients in the USA, Europe, Singapore and Turkey all endeavor to avoid nausea and vomiting as a side effect of anesthesia (21, 27, 28). Considering the degree to which humans desire to avoid experiencing nausea and vomiting associated with anesthesia, the authors anticipated that dog owners would have at least some concern regarding their pet experiencing these side effects.…”

“…Patients who had experienced nausea and/or vomiting post-operatively were willing to pay larger amounts; 127.79 USD in Germany and 131.78 USD in Turkey, respectively (as of May 2019 3 , 4 ) (28). Like patients in the US and Europe, patients from Singapore ranked vomiting and nausea, along with pain as the top 3 adverse outcomes and allotted an equal portion of a hypothetical 100 USD to avoid vomiting and nausea as they would to avoid pain (50 USD each) (27).…”

Objective: The objective of this study was to assess dog owners' concern regarding peri-operative nausea and vomiting, and their willingness to pay for treatment. Design: Descriptive survey. Sample: A survey was administered to 104 dog owning clients with non-emergent surgical (52) or non-surgical (52) appointments at a University teaching hospital. Procedure: Descriptive statistics were calculated. A Mann-Whitney U test was used to detect differences between clients expecting their pet to undergo elective general anesthesia and those that did not. A Spearman's Rank Co-efficient was used to correlate predictive data. Results: Ninety-seven (93%) dog owners had at least some worry regarding their dog experiencing nausea associated with opioid analgesics and anesthesia, with 39/104 (37.5%) moderately to very worried. Forty-one owners (39%) would definitely and 59/104 (56.7%) would likely choose treatment to decrease or prevent signs of nausea. Ninety-four owners (90.4%) had at least some worry regarding vomiting, and 48/104 (46%) indicated they were moderately to very worried. Fifty-three owners (51.4%) would definitely and 49/103 (47.6%) would likely choose treatment to prevent vomiting. The median and mean amount owners were willing to pay was 50 and 76.47 USD, respectively. Ninety-five (91.3%) were likely or very likely to opt for treatment if required to arrive 1 h earlier for their appointment. There was no correlation between age, income, or owner's PONV experience with likelihood of choosing treatment but there was a significant positive correlation with the owner's level of education. Conclusion: Canine owners are concerned with their pets experiencing nausea and vomiting in relation to opioid analgesics and anesthesia and are willing to pay and stay the required time for effective treatment.

Transforming the perioperative medicine care model: The Singapore experience

Anaesth Intensive Care

More than 300 million surgeries are performed worldwide annually. Established perioperative centres in the UK, USA and Australia have demonstrated the impact of improving perioperative care in reducing costs, increasing patient satisfaction and improving population health. Likewise, the surgical burden of care in Asia is increasing, but with sociocultural, economic and epigenetic differences compared to the west. As Singapore’s largest hospital, the Singapore General Hospital pre-admission perioperative clinic sees about 20,000 patients annually. We aim to illustrate Singapore General Hospital’s perioperative model of care to contribute to the paucity of literature describing perioperative programme implementation within Asia, and to encourage the cross-sharing of perioperative practices internationally. Our perioperative framework navigates risk assessment, risk counselling, and mitigation of health, medical and functional risks to better patients’ perioperative outcomes and population health. We have implemented evidence-based pathways for common conditions such as anaemia and malnutrition, including a multidisciplinary programme for the elderly to tackle frailty and reduce length of stay. We describe how we have enhanced local risk profiling with the Combined Assessment of Risk Encountered in Surgery surgical risk calculator derived locally using a gradient boosting machine learning model. Finally, we report clinical outcomes of these interventions and discuss further challenges and new initiatives at each tier of our perioperative model. Our perioperative care model provides a framework that other centres can adopt to promote value-driven care, while catering for differences in the Asian population, thereby promoting evidence-based improvements in the area of perioperative medicine.
