Enzymatic Debridement Compared To Surgical Debridement: A Cost Analysis in a Burn Unit in Spain. ANNALS OF BURNS AND FIRE DISASTERS 2024; 37:45-52. [PMID: 38680833 PMCID: PMC11041863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 03/16/2023] [Indexed: 05/01/2024]
Abstract
The standard care for burns is tangential surgical debridement and subsequent covering, but recently enzymatic debridement has appeared as an alternative. The objective of this study, using an individualised cost-per-patient information system, is to compare the cost per patient of these two alternatives and identify their main determining factors. A non-randomised, retrospective, observational study was carried out with 79 patients, 39 of whom were treated with surgical debridement. The average cost per patient for enzymatic debridement is lower, particularly due to a shorter length of stay of critical hospitalisation (13.7 vs. 18.9 days; €26,101 vs. €33,919), a decreased need for surgical procedures (0.45 vs. 1.28) and a shorter use of operating theatres (53 vs. 202 minutes; €904 vs. €3,000). Age, aetiology, evolution length and percentage TBSA are robust determinants of the cost of care for burn patients. The type of procedure does not appear to significantly affect the cost per patient.

Abstract
BACKGROUND Value-based healthcare (VBHC) is a conceptual framework to improve the value of healthcare by health, care-process and economic outcomes. Benchmarking should provide useful information to identify best practices and therefore a good instrument to improve quality across healthcare organizations. This paper aims to provide a proof-of-concept of the feasibility of an international VBHC benchmarking in breast cancer, with the ultimate aim of being used to share best practices with a data-driven approach among healthcare organizations from different health systems. METHODS In the VOICE community-a European healthcare centre cluster intending to address VBHC from theory to practice-information on patient-reported, clinical-related, care-process-related and economic-related outcomes were collected. Patient archetypes were identified using clustering techniques and an indicator set following a modified Delphi was defined. Benchmarking was performed using regression models controlling for patient archetypes and socio-demographic characteristics. RESULTS Six hundred and ninety patients from six healthcare centres were included. A set of 50 health, care-process and economic indicators was distilled for benchmarking. Statistically significant differences across sites have been found in most health outcomes, half of the care-process indicators, and all economic indicators, allowing for identifying the best and worst performers. CONCLUSIONS To the best of our knowledge, this is the first international experience providing evidence to be used with VBHC benchmarking intention. Differences in indicators across healthcare centres should be used to identify best practices and improve healthcare quality following further research. Applied methods might help to move forward with VBHC benchmarking in other medical conditions.

Assessment of the Effectiveness, Socio-Economic Impact and Implementation of a Digital Solution for Patients with Advanced Chronic Diseases: The ADLIFE Study Protocol. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:3152. [PMID: 36833849 PMCID: PMC9966680 DOI: 10.3390/ijerph20043152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 01/20/2023] [Accepted: 02/07/2023] [Indexed: 06/18/2023]
Abstract
Due to population ageing and medical advances, people with advanced chronic diseases (ACD) live longer. Such patients are even more likely to face either temporary or permanent reduced functional reserve, which typically further increases their healthcare resource use and the burden of care on their caregiver(s). Accordingly, these patients and their caregiver(s) may benefit from integrated supportive care provided via digitally supported interventions. This approach may either maintain or improve their quality of life, increase their independence, and optimize the healthcare resource use from early stages. ADLIFE is an EU-funded project, aiming to improve the quality of life of older people with ACD by providing integrated personalized care via a digitally enabled toolbox. Indeed, the ADLIFE toolbox is a digital solution which provides patients, caregivers, and health professionals with digitally enabled, integrated, and personalized care, supporting clinical decisions, and encouraging independence and self-management. Here we present the protocol of the ADLIFE study, which is designed to provide robust scientific evidence on the assessment of the effectiveness, socio-economic, implementation, and technology acceptance aspects of the ADLIFE intervention compared to the current standard of care (SoC) when applied in real-life settings of seven different pilot sites across six countries. A quasi-experimental trial following a multicenter, non-randomized, non-concurrent, unblinded, and controlled design will be implemented. Patients in the intervention group will receive the ADLIFE intervention, while patients in the control group will receive SoC. The assessment of the ADLIFE intervention will be conducted using a mixed-methods approach.

WtsWrng Interim Comparative Effectiveness Evaluation and Description of the Challenges to Develop, Assess, and Introduce This Novel Digital Application in a Traditional Health System. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13873. [PMID: 36360756 PMCID: PMC9654177 DOI: 10.3390/ijerph192113873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 10/21/2022] [Accepted: 10/22/2022] [Indexed: 06/16/2023]
Abstract
Science and technology have evolved quickly during the two decades of the 21st century, but healthcare systems are grounded in last century's structure and processes. Changes in the way health care is provided are demanded; digital transformation is a key driver making healthcare systems more accessible, agile, efficient, and citizen-centered. Nevertheless, the way healthcare systems function challenges the development (Innovation + Development and regulatory requirements), assessment (methodological guidance weaknesses), and adoption of digital applications (DAs). WtsWrng (WW), an innovative DA which uses images to interact with citizens for symptom triage and monitoring, is used as an example to show the challenges faced in its development and clinical validation and how these are being overcome. To prove WW's value from inception, novel approaches for evidence generation that allows for an agile and patient-centered development have been applied. Early scientific advice from NICE (UK) was sought for study design, an iterative development and interim analysis was performed, and different statistical parameters (Kappa, B statistic) were explored to face development and assessment challenges. WW triage accuracy at cutoff time ranged from 0.62 to 0.94 for the most frequent symptoms attending the Emergency Department (ED), with the observed concordance for the 12 most frequent diagnostics at hospital discharge fluctuating between 0.4 to 0.97; 8 of the diagnostics had a concordance greater than 0.8. This experience should provoke reflective thinking for DA developers, digital health scientists, regulators, health technology assessors, and payers.

Abstract
There is growing interest in cost-effectiveness thresholds as a tool to inform resource allocation decisions in health care. Studies from several countries have sought to estimate health system opportunity costs, which supply-side cost-effectiveness thresholds are intended to represent. In this paper, we consider the role of empirical estimates of supply-side thresholds in policy-making. Recent studies estimate the cost per unit of health based on average displacement or outcome elasticity. We distinguish the types of point estimates reported in empirical work, including marginal productivity, average displacement, and outcome elasticity. Using this classification, we summarise the limitations of current approaches to threshold estimation in terms of theory, methods, and data. We highlight the questions that arise from alternative interpretations of thresholds and provide recommendations to policymakers seeking to use a supply-side threshold where the evidence base is emerging or incomplete. We recommend that: (1) policymakers must clearly define the scope of the application of a threshold, and the theoretical basis for empirical estimates should be consistent with that scope; (2) a process for the assessment of new evidence and for determining changes in the threshold to be applied in policy-making should be created; (3) decision-making processes should retain flexibility in the application of a threshold; and (4) policymakers should provide support for decision-makers relating to the use of thresholds and the implementation of decisions stemming from their application.

Abstract
OBJECTIVE The aim of this study was to investigate the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in women with pelvic inflammatory disease (PID) and the usefulness and cost-effectiveness of a rapid molecular test for the diagnosis and clinical management of PID. METHODS This observational study included 75 patients with mild-to-moderate PID (n=33), severe PID (n=29) and non-specific lower abdominal pain (NSAP) (n=13). CT/NG infections were analyzed using a standard and a rapid test. A cost analysis was carried out. RESULTS Samples of 19 patients (25.3%) were CT/NG positive. Concordance between rapid and standard tests was 100%. No significant differences were observed in the incidence of CT/NG in mild-to-moderate compared to severe PID. Costs differed according only to disease severity. CONCLUSIONS Rapid molecular tests could help with the diagnosis of PID in sexually active women in clinical settings in which a standard technique is not available.

Are Estimates of the Health Opportunity Cost Being Used to Draw Conclusions in Published Cost-Effectiveness Analyses? A Scoping Review in Four Countries. APPLIED HEALTH ECONOMICS AND HEALTH POLICY 2022; 20:337-349. [PMID: 34964092 PMCID: PMC9021093 DOI: 10.1007/s40258-021-00707-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 11/23/2021] [Indexed: 05/19/2023]
Abstract
BACKGROUND When healthcare budgets are exogenous, cost-effectiveness thresholds (CETs) used to inform funding decisions should represent the health opportunity cost (HOC) of such funding decisions, but HOC-based CET estimates have not been available until recently. In recent years, empirical HOC-based CETs for multiple countries have been published, but the use of these CETs in the cost-effectiveness analysis (CEA) literature has not been investigated. Analysis of the use of HOC-based CETs by researchers undertaking CEAs in countries with different decision-making contexts will provide valuable insights to further understand barriers and facilitators to the acceptance and use of HOC-based CETs. OBJECTIVES We aimed to identify the CET values used to interpret the results of CEAs published in the scientific literature before and after the publication of jurisdiction-specific empirical HOC-based CETs in four countries. METHODS We undertook a scoping review of CEAs published in Spain, Australia, the Netherlands and South Africa between 2016 (2014 in Spain) and 2020. CETs used before and after publication of HOC estimates were recorded. We conducted logit regressions exploring factors explaining the use of HOC values in identified studies and linear models exploring the association of the reported CET value with study characteristics and results. RESULTS 1171 studies were included in this review (870 CEAs and 301 study protocols). HOC values were cited in 28% of CEAs in Spain and in 11% of studies conducted in Australia, but they were not referred to in CEAs undertaken in the Netherlands and South Africa. Regression analyses on Spanish and Australian studies indicate that more recent studies, studies without a conflict of interest and studies estimating an incremental cost-effectiveness ratio (ICER) below the HOC value were more likely to use the HOC as a threshold reference. In addition, we found a small but significant impact indicating that for every dollar increase in the estimated ICER, the reported CET increased by US$0.015. Based on the findings of our review, we discuss the potential factors that might explain the lack of adoption of HOC-based CETs in the empirical CEA literature. CONCLUSIONS The adoption of HOC-based CETs by identified published CEAs has been uneven across the four analysed countries, most likely due to underlying differences in their decision-making processes. Our results also reinforce a previous finding indicating that CETs might be endogenously selected to fit authors' conclusions.

Abstract
PURPOSE The occurrence of adverse events (AE) in hospitalized patients substancially increases the risk of disability or death, having a major negative clinical and economic impact on public health. For early identification of patients at risk and to establish preventive measures, different healthcare systems have implemented rapid response systems (RRS). The aim of this study was to carry out a cost-effectiveness analysis of implementing a RRS in a tertiary-care hospital. METHODS We included all the patients admitted to Hospital Clínic de Barcelona from 1 to 2016 to 31 December 2016. The cost-effectiveness analysis was summarized as the incremental cost-effectiveness ratio (incremental cost divided by the incremental effectiveness of the two alternatives, RRS versus non-RRS). The effectiveness of the RRS, defined as improvements in health outcomes (AE, cardiopulmonary arrest and mortality), was obtained from the literature and applied to the included patient cohort. A budget impact analysis on the implementation of the RRS from a hospital perspective was performed over a 5-year time horizon. RESULTS 42,409 patients were included, and 448 (1.05%) had severe AE requiring ICU admission. The cost-effectiveness analysis showed an incremental cost (savings) of EUR - 1,471,101 of RRS versus the non-RRS. The budgetary impact showed a cost reduction of EUR 896,762.00 in the first year and EUR 1,588,579.00 from the second to the fifth year. CONCLUSIONS The present analysis shows the RRS as a dominant, less costly and more effective structure compared to the non-RRS.

Abstract
Background Water quality monitoring at the dialysis units (DU) is essential to ensure an appropriate dialysis fluid quality and guarantee an optimal and safe dialysis treatment to patients. This paper aims to evaluate the effectiveness, economic and organizational impact of automation, digitalization and remote water quality monitoring, through a New Water Technology (NWT) at a hospital DU to produce dialysis water, compared to a Conventional Water Technology (CWT). Methods A before-and-after study was carried out at the Hospital Clínic Barcelona. Data on CWT was collected during 1-year (control) and 7-month for the NWT (case). Data on water quality, resource use and unit cost were retrospective and prospectively collected. A comparative effectiveness analysis on the compliance rate of quality water parameters with the international guidelines between the NWT and the CWT was conducted. This was followed by a cost-minimization analysis and an organizational impact from the hospital perspective. An extensive deterministic sensitivity analysis was also performed. Results The NWT compared to the CWT showed no differences on effectiveness measured as the compliance rate on international requirements on water quality (100% vs. 100%), but the NWT yielded savings of 3,599 EUR/year compared to the CWT. The NWT offered more data accuracy (daily measures: 6 vs. 1 and missing data: 0 vs. 20 days/year), optimization of the DU employees’ workload (attendance to DU: 4 vs. 19 days/month) and workflow, through the remote and continuous monitoring, reliability of data and process regarding audits for quality control. Conclusions While the compliance of international recommendations on continuous monitoring was performed with the CWT, the NWT was efficient compared to the CWT, mainly due to the travel time needed by the technical operator to attend the DU. These results were scalable to other economic contexts. Nonetheless, they should be taken with caution either when the NWT equipment/maintenance cost are largely increased, or the workforce involvement is diminished.

Abstract
Object Low-field intraoperative magnetic resonance (LF-iMR) has demonstrated a slight increase in the extent of resection of intra-axial tumors while preserving patient`s neurological outcomes. However, whether this improvement is cost-effective or not is still matter of controversy. In this clinical investigation we sought to evaluate the cost-effectiveness of the implementation of a LF-iMR in glioma surgery. Methods Patients undergoing LF-iMR guided glioma surgery with gross total resection (GTR) intention were prospectively collected and compared to an historical cohort operated without this technology. Socio-demographic and clinical variables (pre and postoperative KPS; histopathological classification; Extent of resection; postoperative complications; need of re-intervention within the first year and 1-year postoperative survival) were collected and analyzed. Effectiveness variables were assessed in both groups: Postoperative Karnofsky performance status scale (pKPS); overall survival (OS); Progression-free survival (PFS); and a variable accounting for the number of patients with a greater than subtotal resection and same or higher postoperative KPS (R-KPS). All preoperative, procedural and postoperative costs linked to the treatment were considered for the cost-effectiveness analysis (diagnostic procedures, prosthesis, operating time, hospitalization, consumables, LF-iMR device, etc). Deterministic and probabilistic simulations were conducted to evaluate the consistency of our analysis. Results 50 patients were operated with LF-iMR assistance, while 146 belonged to the control group. GTR rate, pKPS, R-KPS, PFS, and 1-year OS were respectively 13,8% (not significative), 7 points (p < 0.05), 17% (p < 0.05), 38 days (p < 0.05), and 3.7% (not significative) higher in the intervention group. Cost-effectiveness analysis showed a mean incremental cost per patient of 789 € in the intervention group. Incremental cost-effectiveness ratios were 111 € per additional point of pKPS, 21 € per additional day free of progression, and 46 € per additional percentage point of R-KPS. Conclusion Glioma patients operated under LF-iMR guidance experience a better functional outcome, higher resection rates, less complications, better PFS rates but similar life expectancy compared to conventional techniques. In terms of efficiency, LF-iMR is very close to be a dominant technology in terms of R-KPS, PFS and pKPS.

Abstract
OBJECTIVE To evaluate preventive interventions on alcohol consumption has been long recommended in Spain. The impact evaluation of structured programs and specific actions for the prevention and treatment of alcohol consumption (PAPTCA) would allow making better informed decisions on public health financing based on the efficiency criteria. To the best of our knowledge, there is no scientific document that illustrates the situation of the PAPTCAs' evaluation in Spain. This paper aims to classify and describe PAPTCAs in Spain, focused on their impact evaluation and information on financing for accountability to society. METHODS A systematic literature review of the PAPTCAs implemented in Spain, from 2000 till 2017, at regional (autonomous communities) and local level was carried out, and a descriptive analysis of the PAPTCA database obtained from the literature review was carried out. RESULTS 145 structured programs and 45 specific actions were identified. Only 25% of structured programs provided an impact evaluation, besides, only 15% presented some information about their financing. Regarding the specific actions, the numbers were less encouraging where 10% provided an impact evaluation while a similar figure of PAPTCAs showed financing information. CONCLUSIONS There is a need to systematize the information of the PAPTCA that serves as an instrument to conduct impact evaluations in Spain. This should ease the scarce presence of evaluative culture in this area and promote the accountability of resources spent on public health to society.

Abstract
BACKGROUND The measurement and valuation of health-related quality of life for and by young people are increasingly important, yet research on the impact of study perspective and validity of preferences obtained from young populations remains limited. OBJECTIVE The objective of this study was to evaluate the feasibility and validity of collecting EQ-5D Youth version (EQ-5D-Y) preferences from adolescents, adults, and adults from a child perspective. METHODS A profile case best-worst scaling (BWS) online survey was administered to representative Australian and Spanish adult (age ≥ 18 years) and child (age 11-17 years) samples. Adults were told to either answer from their own perspective or for a hypothetical 10-year-old child. Marginal best- and worst-choice frequencies, analysis of dominant choices, self-reported difficulty completing the tasks, and time to complete tasks were used to determine the validity of responses. RESULTS In Australia, 2134 adults and 1010 adolescents completed the survey. In Spain, 2007 adults and 1000 adolescents completed it. Analysis of marginal choice frequencies and dominant choices indicated that the pattern of responses between adolescents and adults was similar. For Australian respondents, having no mobility problems was rated as best by adolescents, while adults rated having no pain and discomfort as 'best'. In Spain, both adults and adolescents rated no pain or discomfort as 'best'. Australian adolescents rated very worried, sad or unhappy as 'worst', while Spanish adolescents, Spanish adults and Australian adults rated a lot of pain and discomfort as 'worst'. CONCLUSIONS Results suggest preferences from adolescents using direct BWS are valid. Our descriptive analysis also suggest that there are age-related and country-specific differences in elicitation values for the EQ-5D-Y.

Abstract
There is an extensive body of empirical research that focuses on the societal monetary value of a quality-adjusted life year (MVQALY). Many of these studies have found the estimates to be inversely associated with the size of the health gain, and thus not conforming to the linearity assumption imposed in the QALY model. In this study, we explore the extent to which the MVQALY varies when it is associated with different types and magnitudes of quality of life (QoL) improvements. To allow for a comprehensive assessment, we derive the MVQALY corresponding to the full spectrum of health gains defined by the EQ-5D-3L instrument. The analysis was based on a large and representative sample of the population in Spain. A discrete choice experiment and a time trade-off exercise were used to derive a value set for utilities, followed by a willingness to pay questionnaire. The data were jointly analysed using regression analyses and bootstrapping techniques. Our findings indicate that societal values for a QALY corresponding to different EQ-5D-3L health gains vary approximately between 10,000€ and 30,000€. MVQALY associated with larger improvements on QoL was found to be lower than that associated with moderate QoL gains. The potential sources of the observed non-constant MVQALY are discussed.

Abstract
Introduction: Knowledge about residual deficiencies and their consequences on daily life activities among stroke patients living at home 1-year after the initial event managed in stroke units is poor. This multi-dimensional study assessed the types of deficiencies, their frequency and the consequences that the specific stroke had upon the daily life of patients. Methods: A cross-sectional survey, assessing, using standardized scales, 1 year post-stroke disabilities, limitations of activities, participation and quality of life, was carried out by telephone interview and by mail in a sample of stroke patients who returned home after having been initially managed in a stroke unit. Results: A total of 161 patients were included (142 able to answer the interview on their own; 19 needing a care-giver). Amongst a sub-group of the patients interviewed, 55.4% (95% Confidence Interval [47.1–63.7]) complained about pain and 60.0% (95% CI [51.4–68.6]) complained of fatigue; about 25% presented neuropsychological or neuropsychiatric disability. Whilst 87.3% (95% CI [81.7–92.9]) were independent for daily life activities, participation in every domains and quality of life scores, mainly in daily activity, pain, and anxiety subscales, were low. Conclusion: Despite a good 1-year post-stroke functional outcome, non-motor disabling symptoms are frequent amongst patients returned home and able to be interviewed, contributing to a low level of participation and a poor quality of life. Rehabilitation strategies focused on participation should be developed to break the vicious circle of social isolation and improve quality of life.

Cost-effectiveness analysis of real-time continuous monitoring glucose compared to self-monitoring of blood glucose for diabetes mellitus in Spain. J Eval Clin Pract 2018; 24:772-781. [PMID: 29971893 DOI: 10.1111/jep.12987] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Revised: 06/11/2018] [Accepted: 06/13/2018] [Indexed: 12/13/2022]
Abstract
RATIONALE, AIMS AND OBJECTIVES Self-monitoring of blood glucose (SMBG) is recommended to monitor glycaemic levels. The recent development of real-time continuous glucose monitoring (RT-CGM) enables continuous display of glucose concentration alerting patients in the event of relevant glucose fluctuations, potentially avoiding hypoglycaemic events and reducing long-term complications related to glycosylated haemoglobin (HbA1c) levels. This paper aims to evaluate the cost-effectiveness of RT-CGM compared to SMBG in patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) which should support decision-making on public funding of RT-CGM in Spain. METHODS We performed a systematic review and meta-analyses on the effectiveness of RT-CGM in the reduction of HbA1c levels and severe hypoglycaemic events. A cost-effectiveness analysis was conducted using a Markov model which simulates the costs and health outcomes of individuals treated under these alternatives for a lifetime horizon from the perspective of the Spanish Health Service. The effectiveness measure was quality-adjusted life years (QALYs). We ran extensive sensitivity analyses, including a probabilistic sensitivity analysis. RESULTS Real-time continuous glucose monitoring provides a significant reduction of HbA1c for T1DM (13 studies; weighted mean difference (WMD) = -0.23%, 95% CI: -0.35, -0.11) and T2DM (5 studies; WMD = -0.48%, 95% CI: -0.79, -0.17). There were no statistically significant differences in the rate of severe hypoglycaemic events in T1DM (9 studies; OR = 1.16, 95% CI: 0.78, 1.72) or T2DM (no severe hypoglycaemic events were reported in any study). In the base case analysis, RT-CGM led to higher QALYs and health care costs with an estimated incremental cost-effectiveness ratio of €2 554 723 and €180 553 per QALY for T1DM and T2DM patients respectively. Sensitivity analyses revealed that the study results were robust. CONCLUSIONS Real-time continuous glucose monitoring is not a cost-effective technology when compared to SMBG in Spain.

Estimating a cost-effectiveness threshold for the Spanish NHS. HEALTH ECONOMICS 2018; 27:746-761. [PMID: 29282798 DOI: 10.1002/hec.3633] [Citation(s) in RCA: 156] [Impact Index Per Article: 26.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2016] [Revised: 10/31/2017] [Accepted: 11/28/2017] [Indexed: 05/21/2023]
Abstract
The cost of generating a quality-adjusted life year (QALY) within a National Health Service provides an approximation of the average opportunity cost of funding decisions. This information can be used to inform a cost-effectiveness threshold. The aim of this paper is to estimate the cost per QALY at the Spanish National Health Service. We exploit variation across 17 regional health services and the exogenous changes in expenditure that took place as a consequence of the economic crisis over 5 years of data. We conduct fixed effect models and use an instrumental variable approach to test for potential remaining endogeneity. Our results show that health expenditure has a positive and significant effect on population health, with an average spending elasticity of 0.07. This translates into a cost per QALY of between 22,000€ and 25,000€. These values are below the cost-effectiveness threshold figure of 30,000€ commonly cited in Spain.

Abstract
To incorporate economic evaluation into decision-making, we need to know how much a health system is willing and able to invest in a quality-adjusted life year (QALY). In Spain, the figure of 30,000 per QALY as cost-effectiveness (CE) threshold has been widely cited. However, as in most health systems, no value has been formally adopted; mainly because of the arbitrariness, the lack of theoretical and scientific basis, and the controversy around its estimation and what the threshold should represent. Based on a systematic review of empirical studies on the estimation of the CE threshold undertaken by this research team, we conducted a critical appraisal of the state of the art, using a Delphi with the participation of 13 national experts. This paper contributes to assess the research progress on the CE threshold in Spain, to consider its utility in the decision making process supported by economic evaluation, and to propose further research to improve what has been achieved so far.

On the Estimation of the Cost-Effectiveness Threshold: Why, What, How? VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2016; 19:558-66. [PMID: 27565273 DOI: 10.1016/j.jval.2016.02.020] [Citation(s) in RCA: 108] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2015] [Revised: 02/02/2016] [Accepted: 02/28/2016] [Indexed: 05/19/2023]
Abstract
BACKGROUND Many health care systems claim to incorporate the cost-effectiveness criterion in their investment decisions. Information on the system's willingness to pay per effectiveness unit, normally measured as quality-adjusted life-years (QALYs), however, is not available in most countries. This is partly because of the controversy that remains around the use of a cost-effectiveness threshold, about what the threshold ought to represent, and about the appropriate methodology to arrive at a threshold value. OBJECTIVES The aim of this article was to identify and critically appraise the conceptual perspectives and methodologies used to date to estimate the cost-effectiveness threshold. METHODS We provided an in-depth discussion of different conceptual views and undertook a systematic review of empirical analyses. Identified studies were categorized into the two main conceptual perspectives that argue that the threshold should reflect 1) the value that society places on a QALY and 2) the opportunity cost of investment to the system given budget constraints. RESULTS These studies showed different underpinning assumptions, strengths, and limitations, which are highlighted and discussed. Furthermore, this review allowed us to compare the cost-effectiveness threshold estimates derived from different types of studies. We found that thresholds based on society's valuation of a QALY are generally larger than thresholds resulting from estimating the opportunity cost to the health care system. CONCLUSIONS This implies that some interventions with positive social net benefits, as informed by individuals' preferences, might not be an appropriate use of resources under fixed budget constraints.
