Health literacy is related to different health-related outcomes. However, the nature of the relationship between health literacy and health outcomes is not well understood. One pathway may lead from ...health literacy to health outcomes by means of access to healthcare. The goal of the current study is to explore the association between health literacy and the particular measure of access to healthcare-unmet medical need-for the first time in Croatia and, to the best of our knowledge, for the first time in the EU context. We use data obtained from face-to-face interviews in a large nationally representative sample of the Croatian population (
= 1000) to estimate the level of health literacy and self-reported access to care and investigate the association between health literacy and self-perceived barriers to access. Our study showed that limited and problematic health literacy is prevalent and associated with higher rates of unmet medical need. Unmet need is largely caused by long waiting lists. It is therefore essential to design health services fitting the needs of those who have limited and/or problematic health literacy as well as enhance health education with the potential of improving the access to care and health outcomes as well as design policies that reduce waiting times.
▶ The caregiving effect is the welfare effect of providing informal care, i.e., the effect of the burden of caregiving. The family effect is a direct influence of the health of a patient on others’ ...well-being, i.e., the effects of caring about other people. ▶ TThe caregiving effect can be present only in caregivers while the family effect in the broader group of significant other, regardless of their caregiving status. However, both effects are usually disregarded in economic evaluations which treat patients as isolated individuals. ▶ Using a sample of Dutch informal caregivers we found that both effects exist and may be comparable in size. Our results, while explorative, indicate that economic evaluations adopting a societal perspective should include both the family and the caregiving effects measured in the relevant individuals.
Besides patients’ health and well-being, healthcare interventions may affect the well-being of significant others. Such ‘spill over effects’ in significant others may be distinguished in two distinct effects: (i) the
caregiving effect and (ii)
the family effect. The first refers to the welfare effects of providing informal care, i.e., the effects of caring
for someone who is ill. The second refers to a direct influence of the health of a patient on others’ well-being, i.e., the effects of caring
about other people. Using a sample of Dutch informal caregivers we found that both effects exist and may be comparable in size. Our results, while explorative, indicate that economic evaluations adopting a societal perspective should include both the family and the caregiving effects measured in the relevant individuals.
One possible source of hypothetical bias in willingness to pay (WTP) estimates is response uncertainty, referring to subject's uncertainty about the value of the good under assessment. It has been ...argued that uncertainty can be measured using the post-valuation 'certainty question' that asks: 'How certain are you about your stated WTP?' and marks the degree of certainty on a quantitative or a qualitative scale. Research has shown that the self-reported certainty evaluations can help mitigate hypothetical bias and obtain increasingly accurate WTP estimates. These study reports present a simple test of reliability of post-valuation certainty assessment and then looks at the empirical evidence for clues regarding the general usefulness of certainty adjustment in mitigating hypothetical bias in WTP studies. We find that the post-estimation uncertainty scores are malleable, i.e., significantly correlated with entirely irrelevant information. We conclude that more robust evidence could justify the routine inclusion of certainty evaluation in WTP studies although in the meantime the interpretation of certaintyadjusted WTP values should be approached cautiously.
Abstract Objective The aim of this study was to elicit the individual willingness to pay (WTP) for a quality-adjusted life-year (QALY). Methods In a Web-based questionnaire containing contingent ...valuation exercises, respondents valued health changes in five scenarios. In each scenario, the respondents first valued two health states on a visual analog scale (VAS) and expressed their WTP for avoiding a decline in health from the better health state to the worse, using a payment scale followed by a bounded open contingent valuation question. Analysis WTP per QALY was calculated for QALY gains calculated using VAS valuations, as well as the Dutch EQ-5D tariffs, the two steps in the WTP estimations and each scenario. Heterogeneity in WTP per QALY ratios was examined from the perspective of: 1) household income; and 2) the level of certainty in WTP indicated by respondents. Theoretical validity was analyzed using clustered multivariate regressions. Results A total of 1091 respondents, representative of the Dutch population, participated in the survey. Mean WTP per QALY was €12,900 based on VAS valuations, and €24,500 based on the Dutch EuroQoL tariffs. WTP per QALY was strongly associated with income, varying from €5000 in the lowest to €75,400 in the highest income group. Respondents indicating higher certainty exhibited marginally higher WTP. Regression analyses confirmed expected relations between WTP per QALY, income, and other personal characteristics. Conclusion Individual WTP per QALY values elicited in this study are similar to those found in comparable studies. The use of individual valuations in social decision-making deserves attention, however.
This cost-effectiveness study analyses the expected impacts of activities proposed by the Croatian National Plan Against Cancer (NPAC) on cancer incidence and survival rates, as related to their ...respective costs. We evaluated the impact of the NPAC on two main outcomes, namely, reduced incidence and the improved survival of cancer patients, expressed as life years gained (LYGs), which enabled the calculation of incremental cost-effectiveness ratios (ICERs) in the form of cost per LYG. In the analysis of costs, we considered both the direct costs of NPAC activities as well as the wider indirect societal costs of cancer, thus permitting the calculation of the ICER both from the narrower national health insurer’s perspective (accounting only for the direct costs) and the wider societal perspective (accounting both for the direct and indirect costs). We estimated that on average, for all patients benefiting from the implementation of the NPAC in Croatia, an additional LYG would be yielded at the additional cost of €1.021 (societal perspective). The NPAC can, for some sites, even be considered a dominant intervention due to the negative cost/LYG ratio, meaning that it generates additional LYGs while at the same time, reducing total societal costs. Taking a narrower health insurer’s perspective (i.e., accounting only for the direct costs), the NPAC produces an additional LYG at an additional cost of €1.408. Both cost per LYG estimates can be considered cost-effective investment options.
The paper aims to identify and measure the costs and savings associated with the delivery of Comprehensive Medication Management (CMM) services in Croatia in patients diagnosed with hypertension ...accompanied by at least one additional established cardiovascular disease (CVD) and/or type 2 diabetes mellitus (DMT2) who use five or more medicines daily. The budget impact analysis (BIA) employed in this study compares the total costs of CMM to the cost reductions expected from CMM. The cost reductions (or savings) are based on the reduced incidence of unwanted clinical events and healthcare service utilisation rates due to CMM. The BIA model is populated by data on medication therapy costs, labour, and training from the pilot CMM intervention introduced in Zagreb's main Health Centre, while relevant international published sources were used to estimate the utilisation, incidence, and unwanted clinical events rates. Total direct costs, including pharmacists' labour and training (EUR 2,667,098) and the increase in the cost of prescribed medication (EUR 5,182,864) amounted to EUR 7,849,962 for 3 years, rendering the cost per treated patient per year EUR 57. CMM is expected to reduce the utilisation rates of healthcare services and the incidence of unwanted clinical events, leading to a total 3-year reduction in healthcare costs of EUR 7,787,765. Given the total CMM costs of EUR 7,849,962, CMM's 3-year budget impact equals EUR 92,869, rendering per treated patient an incremental cost of CMM EUR 0.67. Hence, CMM appears to be an affordable intervention for addressing medication mismanagement and irrational drug use.
Estimates of WTP per QALY can be taken as an indication of the monetary value of health gains, which may carry information regarding the appropriate height of the cost-effectiveness threshold. Given ...the far-reaching consequences choosing a particular threshold, and thus the potential relevance of WTP per QALY estimates, it is important to address the validity of these estimates. This study addresses this issue. Our findings offer little support to the validity of WTP per QALY estimates obtained in this study. Implications for general WTP per QALY estimates and further research are discussed.
We estimate the first monetary value of a health gain in Croatia to inform the debate about the appropriate "demand-side" cost-effectiveness thresholds in Croatia but also Central and Eastern Europe, ...where such debates are still uncommon. We test the empirical support for two equity considerations: age and severity operationalized as proportional shortfall (PS), and propose a pragmatic framework for combining equity considerations with the monetary value of health into a single threshold.
We used the contingent valuation method to elicit the willingness to pay per Quality-Adjusted Life Year (QALY) in Croatia, using a representative sample of the population (N = 1,500, online survey). 29 EQ-5D health states were valued using payment scales and open-ended question as payment vehicles. To test the hypotheses, we used both parametric tests and non-parametric tests. Multilinear regression was employed to test the theoretical validity of the results.
The monetary value of a health gain in Croatia is equivalent to 1.15 of GDP per capita (equaling €17,000). Age of patients seems to be an important equity-related characteristic. The WTP per QALY in the age-neutral risk group (€11,900) was nearly equivalent to the WTP per QALY in the adult (neutral) risk group (€11,700) but lower by 16% compared to the WTP per QALY estimated in children (€14,200; p = 0.00). WTP estimates are theoretically valid and to, a small degree, scale sensitive. There is a positive association between the level of proportional shortfall and willingness to pay. To increase the usefulness of our results for the policy-makers, we combine the elicited preferences into a single decision-making framework and construct several cost-effectiveness thresholds based on willingness to pay and equity-related preferences. Based on empirical results, cost-effectiveness thresholds could range up to €20,308 for the most severe health conditions in children or could be lowered to €16,777 for less severe health conditions.
In Central and Eastern Europe, in spite of a growing understanding of the importance of further developing value-based assessment frameworks there has been very little empirical research to guide, inform and promote this development. Countries in this region use mainly GDP-based thresholds without empirical evidence to support such important decisions. This may lead to thresholds that are too high, with detrimental consequence for the pricing and reimbursement systems.
We explored the monetary value of the end-of-life (EoL) health gains, that is, the value of a life-year (VOLY) gained at the end of a patient's life in Croatia. We tested whether the nature of the ...illness under valuation (cancer and/or rare disease) is a factor in the valuation of EoL-VOLYs. The aim was for our results to contribute to the health and longevity valuation literature and more particularly to the debate on the appropriate cost-effectiveness threshold for EoL treatments as well as to provide input into the debate on the justifiability of a cancer and/or a rare disease premium when evaluating therapies.
A contingent valuation was conducted in an online survey using a representative sample of the Croatian population (n = 1500) to calculate the willingness to pay for gains in the remaining life expectancy at the EoL, from the social-inclusive-individual perspective, using payment scales and an open-ended payment vehicle. Our approach mimics the actual decision-making problem of deciding whether to reimburse therapies targeting EoL conditions such as metastatic cancer whose main purpose is to extend life (and not add quality to life).
Average EoL-VOLY across all scenarios was estimated at €67,000 (median €40,000). In scenarios that offered respondents 1 full year of life extension, EoL-VOLY was estimated at €33,000 (median €22,000). Our results show that the type of illness is irrelevant for EoL-VOLY evaluations.
The pressure to reimburse expensive therapies targeting EoL conditions will continue to increase. Delivering "value for money" in healthcare, both in countries with relatively higher and lower budget restrictions, requires the valuation of different types of health gains, which should, in turn, affect our ability to evaluate their cost effectiveness.
The questionnaire format applied in a CV study represents the way in which the WTP estimates are obtained. Payment scales are often used in CV studies as the questionnaire format of choice. The study ...summarized here analyzes the impact of the design of two payment scales (PS) on the monetary value of QALY gains. The scales differed in terms of their end-points, mid points, and coarseness. We judged the performance of the two PS against several indicators: the average WTP per QALY estimates, post-estimation uncertainty levels, the existence of mid-point concentration, and the dependency on endpoints. Our results show that PS design influences respondents' WTP values. The results also suggest that a more detailed scale with a more realistic range may help respondents to elicit values closer to their "true" WTP values, hence produce higher-quality outcomes. Further research and pretesting strategies are suggested to explore and minimize the effects of PS design on WTP estimates, which may ultimately increase the quality of WTP estimates.
