The Impact

Food production is a major contributor to environmental damage. More environmentally sustainable foods could incur higher costs for consumers. In this review, we explore whether consumers are willing to pay (WTP) more for foods with environmental sustainability labels (‘ecolabels’). Six electronic databases were searched for experiments on consumers’ willingness to pay for ecolabelled food. Monetary values were converted to Purchasing Power Parity dollars and adjusted for country-specific inflation. Studies were meta-analysed and effect sizes with confidence intervals were calculated for the whole sample and for pre-specified subgroups defined as meat-dairy, seafood, and fruits-vegetables-nuts. Meta-regressions tested the role of label attributes and demographic characteristics on participants’ WTP. Forty-three discrete choice experiments (DCEs) with 41,777 participants were eligible for inclusion. Thirty-five DCEs (n = 35,725) had usable data for the meta-analysis. Participants were willing to pay a premium of 3.79 PPP$/kg (95%CI 2.7, 4.89, p ≤ 0.001) for ecolabelled foods. WTP was higher for organic labels compared to other labels. Women and people with lower levels of education expressed higher WTP. Ecolabels may increase consumers’ willingness to pay more for environmentally sustainable products and could be part of a strategy to encourage a transition to more sustainable diets.

ObjectiveTo determine the cost-effectiveness of selective digestive decontamination (SDD) as compared to selective oropharyngeal decontamination (SOD) in intensive care units (ICUs) with low levels of antimicrobial resistance.DesignPost-hoc analysis of a previously performed individual patient data meta-analysis of two cluster-randomised cross-over trials.Setting24 ICUs in the Netherlands.Participants12 952 ICU patients who were treated with ≥1 dose of SDD (n=6720) or SOD (n=6232).InterventionsSDD versus SOD.Primary and secondary outcome measuresThe incremental cost-effectiveness ratio (ICER; ie, costs to prevent one in-hospital death) was calculated by comparing differences in direct healthcare costs and in-hospital mortality of patients treated with SDD versus SOD. A willingness-to-pay curve was plotted to reflect the probability of cost-effectiveness of SDD for a range of different values of maximum costs per prevented in-hospital death.ResultsThe ICER resulting from the fixed-effect meta-analysis, adjusted for clustering and differences in baseline characteristics, showed that SDD significantly reduced in-hospital mortality (adjusted absolute risk reduction 0.0195, 95% CI 0.0050 to 0.0338) with no difference in costs (adjusted cost difference €62 in favour of SDD, 95% CI –€1079 to €935). Thus, SDD yielded significantly lower in-hospital mortality and comparable costs as compared with SOD. At a willingness-to-pay value of €33 633 per one prevented in-hospital death, SDD had a probability of 90.0% to be cost-effective as compared with SOD.ConclusionIn Dutch ICUs, SDD has a very high probability of cost-effectiveness as compared to SOD. These data support the implementation of SDD in settings with low levels of antimicrobial resistance.

Data Synthesis

This article outlines a protocol for a meta-analysis into willingness-to-pay (WTP) for farm animal welfare. The analysis seeks to establish the public's WTP for farm animal welfare and whether there is evidence to support niche markets for products produced to designated and usually higher welfare standards. A number of secondary objectives will also be explored in relation to the heterogeneity within the data relating to a number of variables known to vary within existing data including; animal species, welfare measures, socio-demographic and socio-economic characteristics. The protocol outlines the rationale, objectives, inclusion criteria, search strategy and screening processes for the meta-analysis, and the plans for data extraction, risk of bias and data synthesis.

Background: Insulin treatment is necessary for all patients with type 1 diabetes and a subset of patients with type 2 diabetes. However, lifetime insulin treatment is relatively costly that has put a heavy financial burden on insulin-dependent diabetics. Several studies thus have been conducted widely to estimate diabetes patients' willingness to pay (WTP) for insulin therapies worldwide. This study aimed to derive the diabetes patients' WTP for insulin therapy from the results of previous research studies. Methods: A systematic review and meta-analysis of diabetes patients’ WTP for insulin was conducted. All studies were searched and derived from PubMed combined with MeSH, Cochrane library combined with MeSH, ScienceDirect, and Springer Nature. The WTP values were estimated for three different types of insulin, including short-acting, rapid-acting insulin; long-acting, slow-acting insulin, and mixed insulin. Review Manager 5.1.4 software was used to conduct the meta-analysis. Results: Twelve studies were identified by the systematic review, in which eight studies were eligible for a meta-analysis. Most studies were conducted in high-income countries (83.3%), mainly in America (41.7%) and Europe (33.3%). The insulin formulation with the highest mean WTP value was Humalog Mix25 insulin, which was recorded at 410.42 USD per month in the UK and more than 120 USD per month in France, Italy, Spain, and Germany; while most of the other insulin formulations had mean WTP values less than 120 USD per month. Compared to diabetes patients, general populations were willing to pay less for insulin, which was observed in the case of Humalog Mix25 insulin (mean 95.77 USD per month vs 205.89 USD per month) and inhaled insulin (mean 50.43 USD per month compared to more than 120 USD per month). The meta-analysis showed the WTP value for insulin was 74.15 USD per month (95% CI; 55.82 - 92.48). Conclusion: This study showed a comparison of WTP values for different insulin formulations worldwide. The mean WTP value for insulin derived from all previous research may provide an initial understanding of the individuals' preference and WTP. This information could contribute to the effort of managing diabetes and reducing the financial burden of this chronic disease.
