Cost-Effectiveness of Laparoscopic Sleeve Gastrectomy for Chinese Patients.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most popular bariatric surgery procedure in China. However, its cost-effectiveness in Chinese patients is currently unknown. OBJECTIVES: This study aims to assess the cost-effectiveness of LSG vs no surgery in Chinese patients with severe and complex obesity, taking into account both healthcare expenses and the potential improvement in health-related quality of life (HRQoL). METHODS: A retrospective cohort study was conducted, encompassing 135 Chinese patients who underwent LSG between January 3, 2022 and December 29, 2022, at a major bariatric center. The study evaluated the cost-effectiveness from a healthcare service perspective, employing the incremental cost-effectiveness ratio (ICER) for quality-adjusted life years (QALYs) gained. The analyses compared LSG with the alternative of not undergoing surgery over a 1-year period, using actual data, and extended to a lifetime horizon by projecting costs and utilities at an annual discount rate of 3.0%. Subgroup analyses were undertaken to explore cost-effectiveness variations across different sex, age and BMI categories, and diabetes status, employing a one-way analysis of variance (ANOVA). To ensure the reliability of the findings, one-way and probabilistic sensitivity analyses were executed. RESULTS: The results indicated that 1-year post-LSG, patients achieved an average total weight loss (TWL) of (32.7 ± 7.3)% and an excess weight loss (EWL) of (97.8 ± 23.1)%. The ICER for LSG compared to no surgery over a lifetime was $4,327/QALY, significantly below the willingness-to-pay (WTP) threshold for Chinese patients with severe and complex obesity. From a lifetime perspective, LSG proved to be cost-effective for all sex and age groups, across all BMI categories, and for both patients with and without diabetes. Notably, it was more cost-effective for younger patients, patients with higher BMI, and patients with diabetes. CONCLUSIONS: LSG is a highly cost-effective intervention for managing obesity in Chinese patients, delivering substantial benefits in terms of HRQoL improvement at a low cost. Its cost-effectiveness is particularly pronounced among younger individuals, those with higher BMI, and patients with diabetes.

The role and impact of health economics in the optimization of patient care in osteoarthritis: insights from a practical example.

Osteoarthritis (OA) is a degenerative joint disease with a substantial global burden, causing chronic pain and reduced quality of life. Managing OA efficiently while maximizing healthcare resources is crucial. Health economics and health technology assessment (HTA) are central tools providing a framework to evaluate the clinical, economic, and ethical aspects of healthcare technologies and interventions. This article presents some insights into the role of health economics and the HTA process in OA management. It also illustrates an example of cost-effectiveness analysis in a specific healthcare context, on the basis of a recent clinical trial involving hyaluronic acid treatment for knee OA. While HTA offers valuable insights, it faces challenges like data availability and resource constraints. Integrating health economics into decision-making can enhance patient care and allocate resources effectively in OA and other healthcare domains.

The trade-off between COVID-19 and mental diseases burden during a lockdown: Mathematical modeling of control measures.

Background: During the COVID-19 pandemic, many countries used lockdowns as a containment measure. While lockdowns successfully contributed to slowing down the contagion, the related mobility restrictions were reportedly associated with an increased risk of major depressive and anxiety disorders. We aimed to quantify the trade-off between the quality-adjusted life years (QALY) gain due to lower COVID-19 incidence as a result of a lockdown and QALY loss due to lockdown-induced mental disorders. Methods: We developed an agent-based model of COVID-19 epidemic and coupled mental disorder development in the population of a large city. We used data sources on the places of living, studying and working, public health and census surveys. Modeling of mental disorders was based on diathesis-stress concept. We quantified mental and physical health burden in terms of QALY taking into account major depressive and anxiety disorder episodes, lethal and non-lethal cases of COVID-19, and immunization. Findings: We evaluated the dynamics of new major depressive disorder (MDD) and anxiety disorder (AD) cases during the period between September 2020 and December 2021 in Moscow, Russia. We found that lockdown imposition increases the daily chances of getting MDD or ADD by a vulnerable person by 16.79% (95% CI [12.36%, 21.23%]). The QALY loss associated with COVID-19-induced and lockdown-induced mental disorders was estimated to be 18.93% (95% CI [16.94%, 19.73%]) of the total QALY loss caused by COVID-19, immunization, and all kinds of mental disorders. For a synthetic "strong" lockdown, it had been shown that QALY loss is minimized when about 70% of the population are isolated. Interpretation: The burden associated with mental disorders amounts to a considerable part of COVID-19-related losses. Our findings demonstrate that cost-benefit analysis of mobility restriction should include a forecast of mental disorder development in the population.

Preference heterogeneity in health valuation: a latent class analysis of the Peru EQ-5D-5L values.

BACKGROUND: Preference heterogeneity in health valuation has become a topic of greater discussion among health technology assessment agencies. To better understand heterogeneity within a national population, valuation studies may identify latent groups that place different absolute and relative importance (i.e., scale and taste parameters) on the attributes of health profiles. OBJECTIVE: Using discrete choice responses from a Peruvian valuation study, we estimated EQ-5D-5L values on a quality-adjusted life-year (QALY) scale accounting for latent heterogeneity in scale and taste, as well as controlling heteroskedasticity at task level variation. METHOD: We conducted a series of latent class analyses, each including the 20 main effects of the EQ-5D-5L and a power function that relaxes the constant proportionality assumption (i.e., discounting) between value and lifespan. Taste class membership was conditional on respondent-specific characteristics and their experience with the composite time trade-off (cTTO) tasks. Scale class membership was conditional on behavioral characteristics such as survey duration and self-stated difficulty level in understanding tasks. Each analysis allowed the scale factor to vary by task type and completion time (i.e., heteroskedasticity). RESULTS: The results indicated three taste classes: a quality-of-life oriented class (33.35%) that placed the highest value on levels of severity, a length-of-life oriented class (26.72%) that placed the highest value on lifespan, and a middle class (39.71%) with health attribute effects lower than the quality class and lifespan effect lower than the length-of-life oriented class. The EQ-5D-5L values ranged from - 2.11 to 0.86 (quality-of-life oriented class), from - 0.38 to 1.02 (middle class), and from 0.36 to 1.01 (length-of-life oriented class). The likelihood of being a member of the quality-of-life class was highly dependent on whether the respondent completed the cTTO tasks (p-value < 0.001), which indicated that the cTTO tasks might cause the Peru respondents to inflate the burden of health problems on a QALY scale compared to those who did not complete the cTTO tasks. The results also showed two scale classes as well as heteroskedasticity within each scale class. CONCLUSION: Accounting for taste and scale classes simultaneously improveds understanding of preference heterogeneity in health valuation. Future studies may confirm the differences in taste between classes in terms of the effect of quality of life and lifespan attributes. Furthermore, confirmatory evidence is needed on how behavioral variables captured within a study protocol may enhance analyses of preference heterogeneity.

Quality-adjusted life years in macular oedema due to age-related macular degeneration, diabetes and central retinal vein occlusion: the impact of anti-VEGF agents in a tertiary centre in Greece.

INTRODUCTION: Neovascular age-related macular degeneration (nAMD), diabetic macular oedema (DME), and macular oedema due to central retinal vein occlusion (CRVO) are leading causes of vision loss, currently managed with anti-vascular endothelial growth factor injections (anti-VEGF). The aim of this study was to calculate QALYs in patients with nAMD, DME, and CRVO treated with anti-VEGF agents (QALYs+) in a Greek tertiary hospital setting and compare them to theoretical QALYs that the patients would have without treatment (QALYs-). MATERIAL AND METHODS: The study included 143 treatment-naive patients with macular oedema due to nAMD (n = 79), DME (n = 57), and CRVO (n = 7), who received anti-VEGF injections as monotherapy according to the Treat-and-Extend (T&E) protocol. The anti-VEGF agents were ranibizumab and aflibercept in equivalent fractions. QALYs where calculated by the formula QALY = Utility Value × Time, where "Time" refers to the follow-up period of the study. For QALYs-, we assumed that visual acuity remained unchanged during this period. RESULTS: Mean follow-up time was 1.3 ± 1.2 years in the nAMD group, 1 ± 1.3 years in the DME group, and 0.5 ± 1 years in the CRVO group. There was no statistically significant difference between QALYs- and QALYs+ in all three ocular pathologies for the study period (p > 0.05 for each of the three statistical tests performed). DISCUSSION/CONCLUSION: Possible explanations for the lack of significant difference between QALYs - and QALYs + in nAMD, DME, and CRVO groups, may be the short time horizon used in this analysis, the inclusion of data from the better-seeing eye (BSE) and the specific socio-economic, geographical and health care characteristics of this rural Greek area.

The QALY at 50: One story many voices.

Research on quality adjusted life year (QALY) has been underway for just over 50 years, which seems like a suitable milestone to review its history. The purpose of this study is to provide a historical overview of why the QALY was developed, the key theoretical work undertaken by Torrance, Bush and Fanshel and how two seminal papers shaped its subsequent development. Moving the QALY forward - there are several historical and reflective exercises. The historical interplay between politics, policy and the challenges facing the National Health Service (NHS) in formulating the QALY concept in the UK has been explored in some depth already, whilst the conceptualization and development of the methodological framework is relatively underexplored. We address this gap by viewing the QALY through the lens of the methodological debates, reflecting upon two key papers underpinning the QALY methodology and how these methods have been developed over time. In part the changes in technology e.g. Google Scholar, and the availability of tools to search for early uses of the QALY allow us to better understand the historical context in which the theoretical development of the QALY has taken place. Here we celebrate two seminal papers that shaped early QALY development. The first section provides a history of these papers, summaries their contributions and explores the uptake of these papers over time. The second section reviews the methodological debates that have surrounded the QALY over the last 50 years and looks at how the QALY has moved to address these challenges. The third section presents the voices of diverse commentators representing the field of health economics who have contributed to the subsequent development of the QALY in both theoretical and empirical capacities and captures their thoughts about future research and policy use of QALYS.

Preoperative comprehensive geriatric assessment and optimisation prior to elective arterial vascular surgery: a health economic analysis.

BACKGROUND: increasing numbers of older people are undergoing vascular surgery. Preoperative comprehensive geriatric assessment and optimisation (CGA) reduces postoperative complications and length of hospital stay. Establishing CGA-based perioperative services requires health economic evaluation prior to implementation. Through a modelling-based economic evaluation, using data from a single site clinical trial, this study evaluates whether CGA is a cost-effective alternative to standard preoperative assessment for older patients undergoing elective arterial surgery. METHODS: an economic evaluation, using decision-analytic modelling, comparing preoperative CGA and optimisation with standard preoperative care, was undertaken in older patients undergoing elective arterial surgery. The incremental net health benefit of CGA, expressed in terms of quality-adjusted life-years (QALYs), was used to evaluate cost-effectiveness. RESULTS: CGA is a cost-effective substitute for standard preoperative care in elective arterial surgery across a range of cost-effectiveness threshold values. An incremental net benefit of 0.58 QALYs at a cost-effectiveness threshold of £30k, 0.60 QALYs at a threshold of £20k and 0.63 QALYs at a threshold of £13k was observed. Mean total pre- and postoperative health care utilisation costs were estimated to be £1,165 lower for CGA patients largely accounted for by reduced postoperative bed day utilisation. CONCLUSION: this study demonstrates a likely health economic benefit in addition to the previously described clinical benefit of employing CGA methodology in the preoperative setting in older patients undergoing arterial surgery. Further evaluation should examine whether CGA-based perioperative services can be effectively implemented and achieve the same clinical and health economic outcomes at scale.

Cost-Utility Analysis of Wide-Field Imaging as an Auxiliary Technology for Retinopathy of Prematurity Care in Brazil.

Purpose: To evaluate the cost-utility of wide-field imaging (WFI) as a complementary technology for retinopathy of prematurity (ROP) screening from the Brazilian Unified Health System's perspective. Introduction: ROP is one of the leading causes of avoidable childhood blindness worldwide, especially in middle-income countries. The current ROP screening involves indirect binocular ophthalmoscopy (IBO) by ROP expert ophthalmologists. However, there is still insufficient ROP screening coverage. An alternative screening strategy is the combination of WFI with IBO. Methods: A cost-utility analysis was performed using a deterministic decision-tree simulation model to estimate incremental cost-utility for ROP care. Two screening strategies were compared: (1) IBO and (2) combination of WFI of all eligible preterm infants and IBO for type 2 ROP or worse and for non-readable images. Eligible population included preterm infants <32 weeks of gestational age or birth weight equal to or <1,500 g. The temporal horizon was lifetime. Visual outcome data was converted to utility, and the health benefits were estimated on quality-adjusted life-years (QALY). Incremental cost per QALY gained was calculated from the health system perspective. Costs were estimated considering equipment, maintenance, consumables, and staff. A micro-costing approach was used for WFI. Two technician nurses were trained for imaging execution and had their time evaluated. Two ROP expert ophthalmologists had their time evaluated for imaging reading. One-way sensitivity analysis and probabilistic sensitivity analysis were performed. Results: Combined screening strategy resulted in a cost-effective program considering 90% ROP screening coverage. Costs per examination: (1) screening with IBO: US dollar (US $) 34.36; (2) screening with combination: US $58.20; (3) laser treatment: US $642.09; (4) long-term follow-up: ranged from US $69.33 to 286.91, based on the infant's visual function. Incremental cost per QALY gained was US $1,746.99/QALY per infant screened with the combination strategy. One-way sensitivity analysis resulted in cost-effectiveness for all parameters. Probabilistic sensitivity analyses yielded a 100% probability of combination being cost-effective in a willingness-to-pay threshold of US $1,800/QALY. Conclusion: The combined strategy for ROP screening was cost-effective. It enhances access for appropriate ROP care in middle-income countries and dminishes opportunity costs for ophthalmologists.

Problematic cost-utility analysis of interventions for behavior problems in children and adolescents.

Cost-utility analyses are slowly becoming part of randomized control trials evaluating physical and mental health treatments and (preventive) interventions in child and adolescent development. The British National Institute of Health and Care Excellence, for example, insists on the use of gains in Quality Adjusted Life Years (QALYs) to compute the "value for money" of interventions. But what counts as a gain in quality of life? For one of the most widely used instruments, the EuroQol 5 Dimensions scale (EQ-5D), QALYs are estimated by healthy individuals who provide utility scores for specific health states, assuming that the best life is a life without self-experienced problems in five domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The worst imaginable outcome is defined as "a lot of problems" in each of these five domains. The impact of the individual's problems on the social network is not weighted, and important social-developmental domains (externalizing problems, social competence) are missing. Current cost-utility computations based on EQ-5D favor physical health over mental health, and they rely on adult weights for child and adolescent quality of life. Thus, a level playing field is absent, and developmental expertise is sorely missing.

The integrated care pathway for managing post stroke patients (iCaPPS©) in public primary care Healthcentres in Malaysia: impact on quality adjusted life years (QALYs) and cost effectiveness analysis.

BACKGROUND: The delivery of post stroke care is fragmented even in advanced public healthcare systems, globally. Primary care teams are entrusted to provide longer term care for stroke survivors in most developing countries. The integrated Care Pathway for Post Stroke patients (iCaPPS©) was designed to guide primary care teams to incorporate further rehabilitation and regular screening for post stroke complications among patients residing at home in communities, using the shared-care approach, especially in areas with limited access to specialist stroke care services. The iCaPPS© addressed coordination of rehabilitation and screening for post stroke complications which were absent in the current conventional care of patients managed at public primary care healthcentres. This study aimed to evaluate the cost effectiveness and impact of iCaPPS© on quality-adjusted- life-years (QALY) compared with current conventional monitoring at public primary care healthcentres. METHODS: A pragmatic healthcentre-based cluster randomised controlled trial-within trial on 151 post stroke patients from 10 public primary care facilities in Peninsular Malaysia was conducted to evaluate QALY of patients managed with iCaPPS© (n = 86) vs conventional care (n = 65) for 6 months. Costs from societal perspective were calculated, using combination of top down and activity-based costing methods. The 5-level EQ5D (EQ-5D-5 L) was used to calculate health state utility scores. Cost per QALY and incremental cost effectiveness ratio (ICER) were determined. Differences within groups were determined using Mann-Whitney tests. RESULTS: Total costs for 6 months treatment with iCaPPS© was MYR790.34, while conventional care cost MYR527.22. Median QALY for iCaPPS© was 0.55 (0,1.65) compared to conventional care 0.32 (0, 0.73) (z = - 0.21, p = 0.84). Cost per QALY for iCaPPS© was MYR1436.98, conventional care was MYR1647.56. The ICER was MYR1144.00, equivalent to 3.7% of per capita GDP (2012 prices). CONCLUSIONS: Management of post stroke patients in the community using iCaPPS© costs less per QALY compared to current conventional care and is very cost effective.

Cost-Utility of Laparoscopic Roux-en-Y Gastric Bypass in Chinese Patients with Type 2 Diabetes and Obesity with a BMI ≥ 27.5 kg/m2: a Multi-Center Study with a 4-Year Follow-Up of Surgical Cohort.

OBJECTIVES: To find whether Laparoscopic Roux-en-Y gastric bypass (RYGB) surgery was cost effective compared to conventional medical management (CMM) in Chinese patients with type 2 Diabetes(T2D) and obesity with a body mass index (BMI) ≥27.5 kg/m2 in four years. METHODS: A total of 106 obese T2D individuals who underwent RYGB and 106 T2D patients treated with CMM were enrolled from three academic medical centers. Total health related costs, Glycated Hemoglobin A1c (A1C) and BMI was recorded. Cost-Utility Analysis (CUA) was used. Utility values according to results of A1c were obtained from published studies. RESULTS: Improvements were observed in A1C (8.6% at baseline to 6.2% in the first year, p < 0.001) and BMI (30.7 kg/m2 at baseline to 24.3 kg/m2 in the first year, p < 0.001), and the effect lasted for 4 years after RYGB. In the CMM group, A1C fluctuated in four years. The health utility for RYGB group scores 3.756, whereas CMM group scores 3.594 in four years. The total healthcare costs decreased sharply from the second year after RYGB ($8,483 [¥52,596] in the first year to $672[¥4,164] in the second year, p < 0.001) and maintained for 3 years. In the CMM group, the total healthcare costs changed without significance. RYGB costs US$19,359 (¥125,836) per quality-adjusted life years (QALY) gained (incremental cost-utility ratio [ICUR]) compared to CMM, which was lower than a willingness-to-pay (WTP) of $20,277/QALY. CONCLUSIONS: Compared to CMM, RYGB is cost-effective for Chinese patients with type 2 diabetes and obesity 4 years after operation.

Exploring the potential cost-effectiveness of a vocational rehabilitation program for individuals with schizophrenia in a high-income welfare society.

BACKGROUND: Over the past decades research has shown that employment has a positive impact on quality of life, global functioning and recovery in individuals with schizophrenia. However, access to vocational rehabilitation services for this group is limited and unemployment rates remain high. In this study we explore the potential cost-effectiveness of a novel vocational rehabilitation program (The Job Management Program - JUMP) earmarked for individuals with schizophrenia in Norway. METHODS: The JUMP study was a vocational rehabilitation program augmented with either cognitive behaviour therapy or cognitive remediation. In addition to the JUMP protocol, we extracted treatment cost data from comprehensive and mandatory health and welfare registers. The costs over a two-year follow-up period were compared with the costs over the two-year period prior to inclusion in the study. We also compared the cost-effectiveness of JUMP with a treatment as usual group (TAU). RESULTS: We identified significant reductions in inpatient services in the JUMP group, both for those who obtained employment and those who did not. Significant reductions were also found in the TAU group, but adjusted for baseline differences the total cost for JUMP participants were € 10,621 lower than in the TAU group during the follow-up period. CONCLUSION: In addition to supporting individuals with schizophrenia obtain employment, JUMP appears to have reduced the reliance on mental health services, which should be of interest to stakeholders.

Estimating a Preference-Based Single Index Measuring the Quality-of-Life Impact of Self-Management for Diabetes.

OBJECTIVE: Self-management is becoming increasingly important in diabetes but is neglected in conventional preference-based measures. The objective of this paper was to generate health state utility values for a novel classification system measuring the quality-of-life impact of self-management for diabetes, which can be used to generate quality-adjusted life years (QALYs). METHODS: A large online survey was conducted using a discrete choice experiment (DCE), with duration as an additional attribute, on members of the UK general population ( n = 1,493) to elicit values for health (social limitations, mood, vitality, hypoglycaemia) and non-health (stress, hassle, control, support) aspects of self-management in diabetes. The data were modelled using a conditional fixed-effects logit model and utility estimates were anchored on the one to zero (full health to dead) scale. RESULTS: The model produced significant and consistent coefficients, with one logical inconsistency and 3 insignificant coefficients for the milder levels of some attributes. The anchored utilities ranged from 1 for the best state to -0.029 for the worst state (meaning worse than dead) defined by the classification system. CONCLUSION: The results presented here can potentially be used to generate utility values capturing the day to day impact of interventions in diabetes on both health and self-management. These utility values can potentially be used to generate QALYs for economic models of the cost-effectiveness of interventions in diabetes.

[Use of Highly Concentrated Polyunsaturated Fatty Acids for Prevention of Complications After Myocardial Infarction. Cost-Utility Analysis].

Use of highly concentrated ethyl esters of polyunsaturated fatty acids after myocardial infarction (MI) and in patients with heart failure was associated with lower mortality. The goal of this analysis was to perform cost-utility analysis of the use of highly concentrated ethyl esters of polyunsaturated fatty acids after MI (with help of a Markov model) and to find whether its use in some group of patients led to decrease in budget costs. As a result, we have shown that use of highly concentrated ethyl esters of polyunsaturated fatty acids after MI leads to increase in quality-adjusted life expectancy on 0.5 QALY, with incremental cost-effectiveness ratio of 105 thousand rubles per QALY, and net monetary benefit of 780.5 thousand rubles. In the patient subpopulation that receives highly concentrated ethyl esters of polyunsaturated fatty acids for arrhythmia prevention after coronary artery bypass the estimated decrease of budget cost varies between 6 and 50% depending on denominator used.

Therapeutic lumbar facet joint nerve blocks in the treatment of chronic low back pain: cost utility analysis based on a randomized controlled trial.

BACKGROUND: Related to escalating health care costs and the questionable effectiveness of multiple interventions including lumbar facet joint interventions, cost effectiveness or cost utility analysis has become the cornerstone of evidence-based medicine influencing coverage decisions. METHODS: Cost utility of therapeutic lumbar facet joint nerve blocks in managing chronic low back pain was performed utilizing data from a randomized, double-blind, controlled trial with a 2-year follow-up, with direct payment data from 2016. Based on the data from surgical interventions, utilizing the lowest proportion of direct procedural costs of 60%, total cost utility per quality adjusted life year (QALY) was determined by multiplying the derived direct cost at 1.67. RESULTS: Patients in this trial on average received 5.6 ± 2.6 procedures over a period of 2 years, with average relief over a period of 2 years of 82.8 ± 29.6 weeks with 19 ± 18.77 weeks of improvement per procedure. Procedural cost for one-year improvement in quality of life showed USD $2,654.08. Estimated total costs, including indirect costs and drugs with multiplication of direct costs at 1.67, showed a cost of USD $4,432 per QALY. CONCLUSIONS: The analysis of therapeutic lumbar facet joint nerve blocks in the treatment of chronic low back pain shows clinical effectiveness and cost utility at USD $2,654.08 for the direct costs of the procedures, and USD $4,432 for the estimated overall cost per one year of QALY, in chronic persistent low back pain non-responsive to conservative management.

Cost Utility Analysis of Cervical Therapeutic Medial Branch Blocks in Managing Chronic Neck Pain.

Background: Controlled diagnostic studies have established the prevalence of cervical facet joint pain to range from 36% to 67% based on the criterion standard of ≥ 80% pain relief. Treatment of cervical facet joint pain has been described with Level II evidence of effectiveness for therapeutic facet joint nerve blocks and radiofrequency neurotomy and with no significant evidence for intraarticular injections. However, there have not been any cost effectiveness or cost utility analysis studies performed in managing chronic neck pain with or without headaches with cervical facet joint interventions. Study Design: Cost utility analysis based on the results of a double-blind, randomized, controlled trial of cervical therapeutic medial branch blocks in managing chronic neck pain. Objectives: To assess cost utility of therapeutic cervical medial branch blocks in managing chronic neck pain. Methods: A randomized trial was conducted in a specialty referral private practice interventional pain management center in the United States. This trial assessed the clinical effectiveness of therapeutic cervical medial branch blocks with or without steroids for an established diagnosis of cervical facet joint pain by means of controlled diagnostic blocks. Cost utility analysis was performed with direct payment data for the procedures for a total of 120 patients over a period of 2 years from this trial based on reimbursement rates of 2016. The payment data provided direct procedural costs without inclusion of drug treatments. An additional 40% was added to procedural costs with multiplication of a factor of 1.67 to provide estimated total costs including direct and indirect costs, based on highly regarded surgical literature. Outcome measures included significant improvement defined as at least a 50% improvement with reduction in pain and disability status with a combined 50% or more reduction in pain in Neck Disability Index (NDI) scores. Results: The results showed direct procedural costs per one-year improvement in quality adjusted life year (QALY) of United States Dollar (USD) of $2,552, and overall costs of USD $4,261. Overall, each patient on average received 5.7 ± 2.2 procedures over a period of 2 years. Average significant improvement per procedure was 15.6 ± 12.3 weeks and average significant improvement in 2 years per patient was 86.0 ± 24.6 weeks. Limitations: The limitations of this cost utility analysis are that data are based on a single center evaluation. Only costs of therapeutic interventional procedures and physician visits were included, with extrapolation of indirect costs. Conclusion: The cost utility analysis of therapeutic cervical medial branch blocks in the treatment of chronic neck pain non-responsive to conservative management demonstrated clinical effectiveness and cost utility at USD $4,261 per one year of QALY.

Is screening for pancreatic cancer in high-risk groups cost-effective? - Experience from a Danish national screening program.

OBJECTIVE: Pancreatic cancer (PC) is the fourth leading cause of cancer death worldwide, symptoms are few and diffuse, and when the diagnosis has been made only 10-15% would benefit from resection. Surgery is the only potentially curable treatment for pancreatic cancer, and the prognosis seems to improve with early detection. A hereditary component has been identified in 1-10% of the PC cases. To comply with this, screening for PC in high-risk groups with a genetic disposition for PC has been recommended in research settings. DESIGN: Between January 2006 and February 2014 31 patients with Hereditary pancreatitis or with a disposition of HP and 40 first-degree relatives of patients with Familial Pancreatic Cancer (FPC) were screened for development of Pancreatic Ductal Adenocarcinoma (PDAC) with yearly endoscopic ultrasound. The cost-effectiveness of screening in comparison with no-screening was assessed by the incremental cost-utility ratio (ICER). RESULTS: By screening the FPC group we identified 2 patients with PDAC who were treated by total pancreatectomy. One patient is still alive, while the other died after 7 months due to cardiac surgery complications. Stratified analysis of patients with HP and FPC provided ICERs of 47,156 US$ vs. 35,493 US$ per life-year and 58,647 US$ vs. 47,867 US$ per QALY. Including only PDAC related death changed the ICER to 31,722 US$ per life-year and 42,128 US$ per QALY. The ICER for patients with FPC was estimated at 28,834 US$ per life-year and 38,785 US$ per QALY. CONCLUSIONS: With a threshold value of 50,000 US$ per QALY this screening program appears to constitute a cost-effective intervention although screening of HP patients appears to be less cost-effective than FPC patients.
