Willingness and ability to pay for breast cancer treatment among patients from Addis Ababa, Ethiopia: A cross-sectional study. PLoS One 2024; 19:e0300631. [PMID: 38547108 PMCID: PMC10977721 DOI: 10.1371/journal.pone.0300631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 03/02/2024] [Indexed: 04/02/2024] Open
Abstract
INTRODUCTION Breast cancer (BC) is the most common malignant neoplasm among women in Addis Ababa, Ethiopia. The willingness and ability to pay (WATP) for treatment is a contributing factor in the utilization of health care services. The World Health Organization Breast Cancer Initiative calls for 80% of patients to complete multimodality treatment and indicates payment as central factor to improve BC outcome. The objectives of this study are to identify how much female BC patients paid in Addis Ababa for BC treatment, their WATP for BC treatment, and the factors that affect WATP. METHODS The researchers collected data from 204 randomly selected BC patients who were treated in one of four different health facilities (one public and three private) between September 2018 and May 2019. A structured questionnaire was used to assess their WATP for BC treatment and multivariable regression to investigate factors associated with patients' WATP. RESULTS Of interviewed patients, 146 (72%) were at reproductive age. Patients' median expenditure for all BC treatment services was 336 US dollars (USD) in a public cancer center and 926 USD in privately owned health facilities. These amounts are in contrast with a reported WATP of 50 USD and 149 USD. WATP increased with increasing expenditure (OR 1.43; 95% CI 1.09 to 1.89 per 100 US), educational level (OR 1.37; 95% CI 1.02 to 1.85) and service quality (OR 1.34; 95% CI 1.04 to 1.72). In contrast, a monthly income increase by 100 USD corresponds to a 17% decrease of WATP (OR 0.83; 95% CI 0.70 to 0.99). CONCLUSIONS We demonstrated that BC treatment was very expensive for patients, and the cost was much higher than their WATP. Thus, we suggest that BC should be included in both social and community-based health insurance plans and treatment fees should consider patients' WATP.

Abstract
BACKGROUND Empirical support for the appropriate cost-effectiveness threshold (CET) in China remains sparse. OBJECTIVE This study aimed to estimate the willingness to pay (WTP) for cancer prevention and treatment from the perspective of healthcare policy-makers (i.e. supply side) and to investigate whether there is a difference between the estimated WTP in two scenarios. METHODS We conducted a web-based survey from May to July 2022 among experts who offering consultation to the government. We surveyed 79 experts from a national think-tank (84.81% response rate) using contingent valuation method, a method for estimating the monetary value that individuals place on a non-market service. RESULTS The mean WTP for two scenarios were estimated at 1.29 times of per capita Gross Domestic Product (GDP) of China and 1.90 times of per capita GDP, respectively. There was a difference between the WTP in the two scenarios and the WTP for treatment was significantly higher than prevention. CONCLUSION The findings suggest that though there is a smaller gap between the two scenarios in China as compared to other countries, the WTP may vary under different scenarios. So there's a need to further refine the development of CET by adding parameters like prevention instead of defining one universal threshold.

Abstract
INTRODUCTION This study investigates Iranian men's willingness to pay (WTP) for prostate cancer (PCa) screening and influencing factor, along with the impact of information. METHOD We assessed preferences for prostate cancer screening in 771 Iranian men aged 40 and above using an internet-based questionnaire survey. Participants received basic and complementary information, and their willingness to pay was determined through a payment card approach. A Wilcoxon test assessed the impact of information. We also analyzed prostate cancer screening demand and employed Heckman's two-step model to evaluate factors influencing the willingness to pay. Additionally, reasons for unwillingness to pay were explored. RESULTS Willingness to pay significantly decreased with complementary information relative to basic information (16.3$ vs 17.8$). Heckman model, using WTP based on basic information shows age, education, and monthly household expenditure positively influenced the decision to pay. In contrast, health status, expectations of remaining life and prostate problems history positively affect amount of WTP for PCa screening, and insurance coverage has a negative impact on it. Majority of respondents (91%) supported PCa screening, with 82% expressing a willingness to pay. Common reasons for not paying include seeing screening as a public good (43%), financial constraints (35%), and having insurance (20%). The screening demand is price-sensitive. CONCLUSION The basic mindset of Iranian men exaggerates the risk of prostate cancer. Reduced willingness to pay after receiving information reassures the reliability of their financial expectation. Taking into account the factors that influence PCa screening is essential for accurate planning and the successful implementation of this program.

Abstract
OBJECTIVES The German Pharmaceutical Market Restructuring Act (AMNOG, 2011) is a two-stage process to regulate the price of new pharmaceuticals in which price negotiations are conducted based on evidence-based medical benefit assessments using data from prior clinical trials. Although the act does not explicitly set a willingness-to-pay (WTP) threshold, the process itself implicitly establishes a WTP for health improvement. We evaluated the implicit WTP for prescription pharmaceuticals post-AMNOG in the German healthcare system from the decision-maker/payer perspective. METHODS We extracted data on patient-group-specific annual treatment costs and endpoints from 2011 to 2021 from the dossiers assessed by the German Federal Joint Committee (FJC; Gemeinsamer Bundesausschuss). Using incremental cost-effectiveness ratios (ICERs), we calculated a WTP for the indications (I) diabetes, (II) cardiovascular disease, and (III) psoriasis weighted according to patient group size, first from the perspective of the decision-maker (approach A), and second from the perspective of the industry (approach B). To put clinical outcome measures into relation to one another, minimum clinically important differences (MCIDs) were derived from the literature and compared. RESULTS The annual treatment costs of newly authorized drugs were substantially higher (both pre- and post-negotiation) than that of their comparators (e.g., psoriasis, pre-negotiation: €20,601.59, post-negotiation: €16,763.57; comparators: €5178.00). However, although newly launched drugs were more expensive than their comparators, they brought greater medical benefits and were more aligned with value (r = 0.59, P < 0.001) than older drugs. We estimated WTP to vary widely by indication group [€33,814.08 per 1 percentage point hemoglobin A1c (HbA1c) reduction for diabetes, €10,970.83 per life year gained for cardiovascular disease, and €663.46 per 1% PASI decrease for psoriasis; approach A]. WTP was converted to MCID thresholds: diabetes: €16,907.04; cardiovascular drugs: no MCID existent to convert; and psoriasis: €33,173.00. WTP remained constant over time for diabetes and cardiovascular drugs but increased for psoriasis drugs. CONCLUSION This paper is one of the first to estimate the implicit WTP for prescription pharmaceuticals post-AMNOG and suggests that the WTP may vary between different therapeutic areas. Additionally, making different assumptions (approach A versus approach B) with regard to the assumed effectiveness in indication areas that had been declared as having no additional benefit by the FJC may explain the different perspectives of decision-makers and of the pharmaceutical industry on the value of a pharmaceutical.

Abstract
Purpose To identify older Canadians' perception of the importance of expert-generated elements of walking quality, and the contributors to and consequences of perceived walking quality. Method Cross-sectional survey of 649 adults was conducted through a commercial participant panel, Hosted in Canada Surveys. Results Of the 649 respondents, 75% were between 65 and 74 years old (25% ≥ 75) and 49% were women. The most important elements were foot, ankle, hip, and knee mobility with little difference in ranks across walking perception (Fr χ12 = 5.0, p > 0.05). People who were older by a decade were more likely to report poorer walking (POR: 1.4; 95% CI: 1.0, 1.7), as were women compared to men, and people who used a walking aid compared to none. Lung disease showed the highest association with a perception of not walking well (POR: 7.2; 95% CI: 3.7, 14.2). The odds of being willing to pay more for a technology to improve walking were always greater for those with a lower perception of their walking quality. Conclusions People who perceived their walking quality as poor were more likely to report poorer health and were willing to pay more for a technology to improve walking. This supports the opportunity of leveraging wearable technologies to improve walking.

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.

Abstract
INTRODUCTION Stated preference studies are a valuable tool to elicit respondents' willingness to pay (WTP) for goods or services, especially in situations where no market valuation exists. Contingent valuation (CV) is a widely used approach among stated-preference techniques for eliciting WTP if prices do not exist or do not reflect actual costs, for example, when services are covered by insurance. This review aimed to provide an overview of relevant factors determining WTP for health services to support variable selection. METHODS A comprehensive systematic literature search and review of CV studies assessing determinants of WTP for health services was conducted, including 11 electronic databases. Two of the authors made independent decisions on the eligibility of studies. We extracted all determinants used and related p values for the effect sizes (e.g. reported in regression models with WTP for a health service as outcome variable). Determinants were summarised in systematic evidence tables and structured by thematic domains. RESULTS We identified 2082 publications, of which 202 full texts were checked for eligibility. We included 62 publications on 61 studies in the review. Across all studies, we identified 22 WTP determinants and other factors from 5 thematic domains: sociodemographic characteristics, perceived threat, perceived benefit, perceived barriers, and other information. CONCLUSION Our review provides evidence on 22 relevant determinants of WTP for health services, which may be used for variable selection and as guidance for planning CV surveys. Endogeneity should be carefully considered before interpreting these determinants as causal factors and potential intervention targets.

Abstract
Emerging evidence suggests that residential open space (ROS) is beneficial for multiple health outcomes for urban residents. However, the general public's understanding of and demand for the health benefits related to ROS have not been widely explored. This study aims to examine the impact of residents' socioeconomic status and perceptions of landscape health benefits on their willingness to pay (WTP) for ROS and to evaluate the perceived monetary value of different residential landscape elements. An online survey with 1348 respondents was conducted between August 2020 and October 2021 in China using a contingent valuation (CV) method. Respondents perceived the landscape benefits related to mental health to be higher than those related to physical and social health. The perception of landscape health benefits positively affected WTP and the WTP value of ROS. Residents' monthly income was a significant influencing factor for WTP and the latter's value. For individuals with positive WTP, the average annual WTP for ROS was CNY 68.98 (USD 10.81), while for all the respondents, the estimated mean annual WTP for ROS was CNY 91.75 (USD 14.38). Moreover, the estimated WTP for plants was the highest, whereas the WTP for activity spaces was estimated as the lowest. These findings may improve city planners' and community managers' understanding of the perceived value of residential landscapes among the public and help them make effective decisions to build healthy communities.

Abstract
BACKGROUND The coronavirus disease (COVID-19) pandemic has considerably affected the lives of people worldwide, impacting their health and economic welfare, and changing the behavior of our society significantly. This situation may lead to a strong incentive for people to buy a vaccine. Therefore, a relevant study to assess individuals' choices and the value of change in welfare from a COVID-19 vaccine is essential. OBJECTIVE This study aimed to estimate the willingness-to-pay (WTP) value for a vaccine for COVID-19. We also identify the variables that influence individual vaccination decisions, which could be used in the design of vaccination promotion strategies. METHODS We use the contingent valuation method in its double-bounded dichotomous choice format. The estimation coefficients are calculated according to the maximum likelihood method under the assumption of a probit distribution. The sample consisted of 531 individuals, mainly from middle- and high-income socioeconomic groups from Chile between enrolled between 10 July and 10 August 2020. RESULTS The results show a high WTP for the COVID-19 vaccine, with a value up to US$232. Income and education levels and having family members with COVID-19 increased the likelihood of persons paying for a vaccine. There is also a greater fear as the pandemic progresses that people will get sick from COVID-19. CONCLUSIONS The high WTP value creates an opportunity for formulating public health policy. The results of this study suggest that governments can provide the vaccine free to low-income groups and allow those with higher incomes to acquire the vaccine through the private sector by paying. This will be useful especially for countries with economic difficulties.
