Abstract
INTRODUCTION Willingness to pay (WTP) studies examine the maximum amount of money an individual is willing to pay for a specified health intervention, and can be used to inform coverage and reimbursement decisions. Our objectives were to assess how people value cancer-related interventions, identify differences in the methodologies used, and review the trends in studies' publication. AREAS COVERED We extracted PubMed and EconLit articles published in 1997-2020 that reported WTP for cancer-related interventions, characterized the methodological differences and summarized each intervention's mean and median WTP values. We reviewed 1,331 abstracts and identified 103 relevant WTP studies, of which 37 (36%) focused on treatment followed by screening (26), prevention (21), diagnosis (7) and other interventions (12). The methods used to determine WTP values were primarily discrete-choice questions (n = 54, 52%), bidding games (15), payment cards (12) and open-ended questions (12). We found a wide variation in WTP reported values ranged from below $100 to over $20,000. EXPERT OPINION The WTP literature on oncology interventions has grown rapidly. There is considerable heterogeneity with respect to the type of interventions and diseases assessed, the respondents' characteristics, and the study methodologies. This points to the need to establish international guidelines for best practices in this field.

Vásquez WF, Trudeau JM. Will Americans Get Vaccinated? Predicting COVID-19 Vaccine Uptake Rates Under Contingent Scenarios. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2021; 24:1543-1550. [PMID: 34711354 PMCID: PMC8339597 DOI: 10.1016/j.jval.2021.05.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Revised: 05/10/2021] [Accepted: 05/23/2021] [Indexed: 06/02/2023]
Abstract
OBJECTIVES Amid a pandemic, vaccines represent a promising solution for mitigating public health and economic crises, and an improved understanding of individuals' vaccination intentions is crucial to design optimal immunization campaigns. This study predicts uptake rates for different COVID-19 vaccine specifications and identifies personal characteristics that moderate an individual's responsiveness to vaccine attributes. METHODS We developed an online survey with contingent specifications of a COVID-19 vaccine, varying in effectiveness, risks of side effects, duration of immunity, and out-of-pocket cost. Using population-averaged logit models, we estimated vaccine uptake rates that account for uncertainty, heterogeneity across respondents, and interactions between vaccine and personal characteristics. RESULTS We obtained 3047 completed surveys. The highest uptake rate for an annual vaccine, 62%, is predicted when vaccine effectiveness is 80% to 90%, side effects are minimal, and the vaccine is provided at zero cost, with decreases seen in the uptake rate for less effective vaccines, for example, 50% for 50% to 60% effectiveness. Moreover, we found that Americans' response to vaccine effectiveness depends on their self-reported concern, that is, concerned respondents report a higher willingness to get vaccinated. Our findings also indicate that COVID-19 vaccine uptake rates decrease with vaccine cost and that responsiveness to vaccine cost is moderated by income. CONCLUSIONS Although providing the COVID-19 vaccine at zero cost will motivate many individuals to get vaccinated, a policy focused exclusively on vaccine cost may not be enough to reach herd immunity thresholds. Although those concerned with COVID-19 will participate, further evidence is needed on how to incentivize participation among the unconcerned (43%) to prevent further pandemic spread.

Abstract
OBJECTIVES To systematically review studies eliciting monetary value of a statistical life (VSL) estimates within, and across, different sectors and other contexts; compare the reported estimates; and critically review the elicitation methods used. METHODS In June 2019, we searched the following databases to identify methodological and empirical studies: Cochrane Library, Compendex, Embase, Environment Complete, Informit, ProQuest, PubMed, Scopus, and Web of Science. We used the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines for reporting and a modified Consolidated Health Economic Evaluation Reporting Standards checklist to assess the quality of included studies. RESULTS We identified 1455 studies, of which we included 120 in the systematic review. A stated-preference approach was used in 76 articles, with 51%, 41%, and 8% being contingent valuation studies, discrete-choice experiments, or both, respectively. A revealed-preference approach was used in 43 articles, of which 74% were based on compensating-wage differentials. The human capital approach was used in only 1 article. We assessed most publications (87%) as being of high quality. Estimates for VSL varied substantially by context (sector, developed/developing country, socio-economic status, etc), with the median of midpoint purchasing power parity-adjusted estimates of 2019 US$5.7 million ($6.8 million, $8.7 million, and $5.3 million for health, labor market, and transportation safety sectors, respectively). CONCLUSIONS The large variation observed in published VSLs depends mainly on the context rather than the method used. We found higher median values for labor markets and developed countries. It is important that health economists and policymakers use context-specific VSL estimates. Methodological innovation and standardization are needed to maximize comparability of VSL estimates within, and across, sectors and methods.

Abstract
BACKGROUND Keratinocyte carcinoma (KC) treatment accounts for approximately $5 billion in spending per year, yet no studies have evaluated the US general public's willingness to pay (WTP) for these procedures. OBJECTIVE To determine the monetary value of surgical KC treatments, as perceived by society, as a measure of preference. PARTICIPANTS, METHODS AND MATERIALS We performed an internet-based age-, sex-, and race-stratified cross-sectional survey of 425 subjects representative of the US general population. Stated WTP and desirability of electrodesiccation and curettage (EDC), excision, and Mohs micrographic surgery (MMS) for facial and extrafacial basal cell carcinoma (BCC) were assessed. A discrete choice experiment was performed using maximum likelihood estimation, and a secondary analysis was performed to determine the influence of framing MMS as the best treatment option. RESULTS A total of 425 subjects finished their questionnaires, yielding a completion rate of 97%. Median (interquartile range) stated WTP for EDC, excision, and MMS were $1,000 (421-2,079), $1,503 (562-3,062), and $3,006 (1,250-5,084), respectively, when MMS was framed in a standard fashion. Stated WTP for MMS increased to $3,989 (2,015-5,801) when it was framed as the best option. For BCC on the back, WTP for MMS dropped by 12%. CONCLUSION There is markedly higher societal WTP for MMS on both the face and trunk, regardless of whether MMS is framed as the best option. Gold-standard bias may affect WTP and desirability in medical decision-making under uncertainty, inflating the WTP of options framed as the best while decreasing the desirability of alternatives.

Abstract
Background: The Willingness to pay (WTP) for and acceptance of cervical cancer prevention (CCP) methods have an important role in the control of this type of cancer. Therefore, the aim of this study was to estimate the WTP and acceptance of CCP methods with the contingent valuation method (CVM). Methods: In this systematic review and meta-analysis study, the required information was collected by searching relevant keywords in PubMed, Scopus, Embase, Web of Knowledge, and their Persian equivalent in the Scientific Information Database (SID) and Elmnet databases during January 1, 2000 to June 30, 2020. All studies that reported the WTP and CCP methods with the CVM in English or Persian were included. The reporting quality of studies was assessed by strengthening the Reporting of Observational Studies in Epidemiology (STROBE). Comprehensive meta-analysis (CMA: 2) software was used to conduct the meta-analysis. The content analysis method was used for qualitative data analysis. Results: Finally, 28 articles (with 49610 people) were included in the study. Most of the participants were women (35.7%). The HPV vaccine was the most common method of prevention (75%). The overall acceptance rate was 64% and the overall positive WTP rate was 66%. The average WTP was US$30.44, which accounts for about 0.84% of GDP per capita. The most significant effective factors included income, age, education, high-risk sexual behaviors, and awareness of cervical cancer, belief in the risk of cervical cancer, and belief about the effectiveness of prevention methods. The cost was the most important reason for the unwillingness to pay and accept. Conclusion: Results show that the WTP and acceptance rate of CCP methods are relatively high. It is recommended to reduce the cost of prevention methods, especially the HPV vaccine, and to increase awareness and improve the attitude of people. Also, it is recommended to consider other methods of estimation of WTP and other cancers in future studies.

Abstract
Background: The objective of this study is to determine the influence of dental students’ knowledge and attitude
regarding human papillomavirus infection of cervical cancer on willingness to pay for vaccination. Basic research
design: A convenience sampling method was used. The minimal sample size of 136 was calculated using the Raosoft
calculator with a 5 % margin of error and 95% confidence level. Participants: The study population were all final
year dental students from the School of Dentistry. Methods: A self-administered questionnaire was used to measure
knowledge levels and attitudes regarding human papillomavirus vaccination. Contingent valuation was conducted
for willingness to pay for vaccination. Main outcome measures: The Center for Disease Control and Prevention has
stated that human papillomavirus are associated with oropharynx cancer and the American Dental Association insist on
expanding public awareness of the oncogenic potential of some HPV infections. Thus, as future dental practitioners,
dental students should be aware of human papillomavirus and their links with cancer and the benefits of vaccination.
Results: Knowledge on HPV and cervical cancer did not impact on attitudes towards vaccines. However, significant
correlation existed between knowledge and willingness to pay for vaccination. Conclusions: Dental students’ knowledge
on HPV and cervical cancer has no influence on their attitude towards HPV vaccines. However, their willingness to
pay for HPV vaccination is influenced by their knowledge of cervical cancer and HPV vaccination.

Abstract
In Taiwan, cervical cancer is ranked sixth among all causes of death in women. With the goal of reducing the incidence of cervical cancer, the Kinmen County Health Bureau planned to implement a pilot human papillomavirus (HPV) vaccination program in 2007. The Bureau established a committee to promote public awareness, coordinate with the schools, arrange for the administration of the vaccine, establish a vaccination registry, and develop a plan for follow-up and assessment. Vaccination for female residents aged 16-18 began through a school-based program in 2008. A total of 1633 girls completed the vaccination protocol within 3 years, and vaccine uptake rates of over 90% were achieved by 2010. No serious adverse events were reported among those who were vaccinated. The experience gained from the Kinmen County HPV vaccination program has helped and will continue to help establish an operational model for similar programs throughout the country.

Abstract
Governments constantly face the challenge of determining how much they should spend to prevent premature deaths and suffering in their populations. In this article we explore the benefits of expanding the delivery of life-saving vaccines in seventy-two low- and middle-income countries, which we estimate would prevent the deaths of 6.4 million children between 2011 and 2020. We present the economic benefits of vaccines by using a "value of statistical life" approach, which is based on individuals' perceptions regarding the trade-off between income and increased risk of mortality. Our analysis shows that the vaccine expansion described above corresponds to $231 billion (uncertainty range: $116-$614 billion) in the value of statistical lives saved. This analysis complements results from analyses based on other techniques and is the first of its kind for immunizations in the world's poorest countries. It highlights the major economic benefits made possible by improving vaccine coverage.
