RESUMO

Background. Fecal microbial transplantation (FMT) is the delivery of fecal microbiome, isolated from healthy donors, into a patient's gastrointestinal tract. FMT is a safe and efficient treatment for recurrent Clostridioides difficile infection. Donors undergo strict screening to avoid disease transmission. This consists of several blood and stool tests, which are performed in a multistage, costly process. We performed a cost-minimizing analysis to find the optimal order in which the tests should be performed. Methods. An algorithm to optimize the order of tests in terms of cost was defined. Performance analysis for disqualifying a potential healthy donor was carried out on data sets based on either the published literature or our real-life data. For both data sets, we calculated the total cost to qualify a single donor according to the optimal order of tests, suggested by the algorithm. Results. Applying the algorithm to the published literature revealed potential savings of 94.2% of the cost of screening a potential donor and 7.05% of the cost to qualify a single donor. In our cohort of 87 volunteers, 53 were not eligible for donation. Of 34 potential donors, 10 were disqualified due to abnormal lab tests. Applying our algorithm to optimize the order of tests, the average cost for screening a potential donor resulted in potential savings of 49.9% and a 21.3% savings in the cost to qualify a single donor. Conclusions. Improving the order and timing of the screening tests of potential FMT stool donors can decrease the costs by about 50% per subject. Highlights: What is known:Fecal microbial transplantation (FMT) is the transfer of microbiome from healthy donors to patients.Fecal donors undergo multiple strict screening tests to exclude any transmissible disease.Screening tests of potential fecal donors is expensive and time consuming.FMT is the most efficient treatment for recurrent C difficile infection.What is new here:An algorithm to optimize the order of donors' screening tests in terms of cost was defined.Optimizing the order tests can save nearly 50% in costs of screening a potential donor.

RESUMO

BACKGROUND: National second-trimester scanning of cervical length was introduced in Israel in 2010, and in the decade thereafter, a significant systematic reduction in preterm birth and in the delivery of low birthweight babies was found among singletons. OBJECTIVE: In this study, we sought to estimate the cost-effectiveness of a national policy mandating second-trimester cervical length screening by ultrasound, followed by vaginal progesterone treatment for short cervical length in comparison with no screening strategy. STUDY DESIGN: We constructed a decision model comparing 2 strategies, namely (1) universal cervical length screening, and (2) no screening strategy. This study used the national delivery registry of Israel's Ministry of Health. All women diagnosed with a second-trimester cervical length <25 mm were treated with vaginal progesterone and were monitored with a bimonthly ultrasound scan for cervical dynamics and threat of early delivery. Preterm birth prevalence associated with short cervical length, the efficacy of progesterone in preterm birth prevention, and the accuracy of cervical length measurements were derived from previous studies. The cost of progesterone and bimonthly sonographic surveillance, low birthweight delivery, newborn admission to intensive care units, the first-year costs of managing preterm birth and low birthweight, and instances of handicaps and the cost of their follow-up were extracted from the publicly posted registry of Israel's Ministry of Health and Israel Social Securities data. Monte Carlo simulations decision tree mode, Tornado diagrams, and 1- and 2-way sensitivity analyses were implemented and the base case and sensitivity to parameters that were predicted to influence cost-effectiveness were calculated. RESULTS: Without cervical length screening, the discounted quality-adjusted life years were 30.179, and with universal cervical length screening, it increased to 30.198 (difference of 0.018 quality-adjusted life years). The average cost of no screening for cervical length strategy was $1047, and for universal cervical length screening, it was reduced to $998. The calculated incremental cost-effectiveness ratio was -$2676 per quality-adjusted life year (dividing the difference in costs by the difference in quality-adjusted life years). Monte Carlo simulation of cervical length screening of 170,000 singleton newborns (rounded large number close to the number of singleton newborns in Israel) showed that 95.17% of all babies were delivered at gestational week ≥37 in comparison with 94.46% of babies with the no screening strategy. Given 170,000 singleton births, the national savings of screening for short cervical length when compared with no cervical length screening amounted to $8.31M annually, equating to $48.84 for a base case, and the incremental cost-effectiveness ratio for each case of low birthweight or very low birthweight avoided was -$14,718. A cervical length <25 mm was measured for 30,090 women, and of those, 24,650 were false positives. The major parameters that affected the incremental cost-effectiveness ratio were the incidence of preterm birth, the specificity of cervical length measurements, and the efficacy of progesterone treatment. At a preterm birth incidence of <3%, universal screening does not lead to a cost saving. CONCLUSION: National universal cervical length screening should be incorporated into the routine anomaly scan in the second trimester, because it leads to a drop in the incidence of preterm birth and low birthweight babies in singleton pregnancies, thereby saving costs related to the newborn and gaining quality-adjusted life years.

RESUMO

BACKGROUND: Colorectal cancer (CRC) incidence at ages <50 years is increasing worldwide. Screening initiation was lowered to 45 years in the United States. The cost-effectiveness of initiating CRC screening at 45 years in Israel was assessed with the aim of informing national policy and addressing internationally relevant questions. METHODS: A validated CRC screening model was calibrated to Israeli data and examined annual fecal immunochemical testing (FIT) or colonoscopy every 10 years from 45 to 74 years (FIT45-74 or Colo45-74) versus from 50 to 74 years (FIT50-74 or Colo50-74). The addition of a fourth colonoscopy at 75 years was explored, subanalyses were performed by sex/ethnicity, and resource demands were estimated. RESULTS: FIT50-74 and Colo50-74 reduced CRC incidence by 57% and 70% and mortality by 70% and 77%, respectively, versus no screening, with greater absolute impact in Jews/Other versus Arabs but comparable relative impact. FIT45-74 further reduced CRC incidence and mortality by an absolute 3% and 2%, respectively. With Colo45-74 versus Colo50-74, CRC cases and deaths increased slightly as three colonoscopies per lifetime shifted to 5 years earlier but mean quality-adjusted life-years gained (QALYGs) per person increased. FIT45-74 and Colo45-74 cost 23,800-53,900 new Israeli shekels (NIS)/QALYG and 110,600-162,700 NIS/QALYG, with the lowest and highest values among Jewish/Other men and Arab women, respectively. A fourth lifetime colonoscopy cost 48,700 NIS/QALYG. Lowering FIT initiation to 45 years with modest participation required 19,300 additional colonoscopies in the first 3 years. CONCLUSIONS: Beginning CRC screening at 45 years in Israel is projected to yield modest clinical benefits at acceptable costs per QALYG. Despite different estimates by sex/ethnicity, a uniform national policy is favored. These findings can inform Israeli guidelines and serve as a case study internationally.

RESUMO

OBJECTIVE: To determine the best timing for surgical intervention for adults with recurrent tonsillitis (RT). METHODS: A Markov model was constructed using variables and ranges based upon a literature review. A 1-way sensitivity analysis was performed to evaluate the number of yearly bouts at which each algorithm (antibiotics or tonsillectomy) would be favored. A Monte-Carlo probabilistic sensitivity analysis was calculated for gains and cost. Model outcomes were measured with quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICER) for tonsillectomy versus repeat antibiotic treatment. RESULTS: Patients expected to sustain a single annual tonsillitis event will have a negative QALY of 0.02 if treated with surgery and those with 2 annual events will have a QALY gain from undergoing tonsillectomy of 0.01, 3 events = 0.03, 4 events = 0.05, 5 events = 0.07, 6 events = 0.09, 7 events = 0.1, and 8 events = 0.11. These gains became meaningful only after 2 years of recurrent bouts. The average cost of tonsillectomy was 3,238 USD, and the overall average cost of RT was 7,069 USD (an incremental cost of 3,831 USD). The ICER of tonsillectomy over antibiotic treatment for 1 QALY gain was 44,741 USD. CONCLUSION: Adult patients who sustain more than 3 annual bouts of tonsillitis over a period of at least 2 years will gain QALY after tonsillectomy. These gains increase proportionally to the number of yearly events and perennial episodes. The incremental costs of tonsillectomy fail to meet the NICE guidelines but are within other acceptable reference ranges. LEVEL OF EVIDENCE: NA Laryngoscope, 134:2153-2161, 2024.

RESUMO

We aimed to investigate the cost-effectiveness of open surgery, compared to minimally invasive radical hysterectomy for early-stage cervical cancer, using updated survival data. Costs and utilities of each surgical approach were compared using a Markovian decision analysis model. Survival data stratified by surgical approach and surgery costs were received from recently published data. Average costs were discounted at 3%. The value of health benefits for each strategy was calculated using quality-adjusted life years (QALYs). Incremental cost-effectiveness ratio, calculated using the formula (average cost minimal invasive surgery-average cost open surgery)/(average QALY minimal invasive surgery-average QALY open surgery), was used for cost-effectiveness analysis. One-way sensitivity analysis was conducted for all variables. Open radical hysterectomy was found to be cost-saving compared to minimally invasive surgery with an incremental cost-effectiveness ratio of USD -66 and USD -373 for laparoscopic and robotic surgery, respectively. The most influential parameters in the model were surgery costs, followed by the disutility involved with open surgery. Until further data are generated regarding the survival of patients with early-stage cervical cancer treated by minimally invasive surgery, at current pricing, open radical hysterectomy is cost-saving compared to minimally invasive radical hysterectomy, both laparoscopic and robotic.

RESUMO

Molecular testing for thyroid nodules has been rapidly developed in recent years, aiming to predict the presence of malignancy and aggressive features. While commonly utilized to predict malignancy, its role in guiding the management approach is still developing. The high cost of genetic tests and long-term sequences of thyroid cancer is limiting to real-life studies. Objective: To evaluate the cost effectiveness of molecular testing for low-risk differentiated thyroid cancer (lrDTC). Methods: We developed a Markovian decision tree model of a simulated lrDTC cohort, comparing two management strategies: (I) Conducting genetic tests (GT)-patients are stratified into three risk groups for distant metastasis by the identified molecular markers: low-, intermediate- and high-risk molecular profile; followed by management accordingly: patients with low-risk will undergo hemithyroidectomy (HT), patients with intermediate-risk will undergo total thyroidectomy (TT), and high-risk patients will undergo TT with central neck dissection; (II) Without genetic tests (wGT)-all patients will undergo HT according to the ATA recommendations for lrDTC. Outcomes were measured as quality-adjusted life years (QALYs) and costs of each strategy. Results: GT was found as cost effective, leading to a gain of 1.7 QALYs with an additional cost of $327 per patient compared to wGT strategy. This yielded an incremental cost-effectiveness ratio of $190 per QALY. Sensitivity analysis demonstrated robust results across the variables' ranges. The most impactful variable was the benefit from performing TT rather than HT for intermediate to high-risk patients. Conclusions: Our model found that molecular testing for lrDTC is cost-effective, allowing tailored management according to the patient's personal risk level reflected in the genetic profile, hence improving outcomes.

RESUMO

BACKGROUND: The safe consumption of foods depends on their allergen content in relation to patients' lowest observed adverse effect level (LOAEL) and no observed adverse effect level (NOAEL), as well as other factors. In the case of milk, data on LOAEL and NOAEL are limited and conflicting. OBJECTIVE: To determine the threshold dose distribution and the lowest individual eliciting dose (ED) for milk in a large group of milk-allergic patients METHODS: Individuals with confirmed cow's milk allergy who underwent a diagnostic or pre-oral immunotherapy open milk oral food challenge at the Institute of Allergy, Immunology, and Pediatric Pulmonology at Shamir Medical Center between 2010 and 2015 were included. A subgroup of patients with severe milk allergy underwent a modified challenge with a 90- to 120-minute interval after a starting dose of 0.3 mg cow's milk protein. RESULTS: A total of 866 participants (193 with diagnostic challenges and 673 with pre-oral immunotherapy challenges) were included in the study. The discrete ED01 and ED05, or values derived in which 1% or 5% of the respective allergic population would be predicted to experience an allergic reaction, were 1.1 to 1.9 and 4.7 to 5.6 mg milk protein, respectively, and values for cumulative doses for ED01 and ED05 were 0.9 to 1.8 and 5.2 to 6.2 mg milk protein, respectively. No patients, including the most severely milk-allergic individuals who underwent the modified challenge, reacted to the first 0.3 mg protein dose. CONCLUSION: This report provides valuable information about milk NOAELs, LOAELs, and EDs that might assist regulators in decisions about food labeling in general, and milk in particular.

RESUMO

Enhanced recovery protocols and robotic approaches to radical cystectomy are known to reduce perioperative complications; however, the most cost-effective strategy is unknown. We aim to assess the cost effectiveness of radical cystectomy with different surgical techniques and perioperative treatment protocols. We performed a meta-analysis of studies comparing open radical cystectomy (ORC), robotic assisted radical cystectomy (RARC) using extracorporeal (ECUD) or intracorporeal urinary diversion (ICUD) and enhanced recovery after surgery (ERAS) protocols. Operative time, transfusion, complication, Ileus, length of stay and re-admission rates were extracted. US costs for surgery, treatment, hospitalization and complications were obtained from the literature. Israeli costs were obtained from hospital administrative data. Two cost effectiveness models (US and Israel) were developed. The two most cost-effective strategies in both models were ORC with ERAS and RARC with ICUD and ERAS. RARC with ERAS produced the two most effective strategies with ICUD being dominant over ECUD. All strategies implementing the ERAS protocol were more effective than their parallel non-ERAS strategies. RARC with ICUD and ERAS is cost effective compared to ORC. ERAS protocol improves treatment effectiveness and lowers overall costs. ICUD was shown to be more effective and less costly in comparison to ECUD.

RESUMO

BACKGROUND: Gynecologic oncologists should be aware of the option of conception through IVF/PGT-M for families with high BRCA related morbidity or mortality. Our objective was to investigate the cost-effectiveness of preimplantation genetic testing for selection and transfer of BRCA negative embryo in BRCA mutation carriers compared to natural conception. METHODS: Cost-effectiveness of two strategies, conception through IVF/PGT-M and BRCA negative embryo transfer versus natural conception with a 50% chance of BRCA positive newborn for BRCA mutation carriers was compared using a Markovian process decision analysis model. Costs of the two strategies were compared using quality adjusted life years (QALYs'). All costs were discounted at 3%. Incremental cost effectiveness ratio (ICER) compared to willingness to pay threshold was used for cost-effectiveness analysis. RESULTS: IVF/ PGT-M is cost-effective with an ICER of 150,219 new Israeli Shekels, per QALY gained (equivalent to 44,480 USD), at a 3% discount rate. CONCLUSIONS: IVF/ PGT-M and BRCA negative embryo transfer compared to natural conception among BRCA positive parents is cost effective and may be offered for selected couples with high BRCA mutation related morbidity or mortality. Our results could impact decisions regarding conception among BRCA positive couples and health care providers.

RESUMO

AIMS: Bicuspid aortic valve (BAV) is the commonest congenital heart valve malformation, and is associated with life-threatening complications. Given the high heritability index of BAV, many experts recommend echocardiography screening for first-degree relatives (FDRs) of an index case. Here, we aim to evaluate the cost-effectiveness of such cascade screening for BAV. METHODS AND RESULTS: Using a decision-analytic model, we performed a cost-effectiveness analysis of echocardiographic screening for FDRs of a BAV index case. Data on BAV probabilities and complications among FDRs were derived from our institution's BAV familial cohort and from the literature on population-based BAV cohorts with long-term follow-up. Health gain was measured as quality-adjusted life years (QALYs). Cost inputs were based on list prices and literature data. One-way and probabilistic sensitivity analyses were performed to account for uncertainty in the model's variables. Screening of FDRs was found to be the dominant strategy, being more effective and less costly than no screening, with savings of €644 and gains of 0.3 QALY. Results were sensitive throughout the range of the main model's variables, including the full range of reported BAV rates among FDRs across the literature. A gradual decrease of the incremental effect was found with the increase in screening age. CONCLUSION: This economic evaluation model found that echocardiographic screening of FDRs of a BAV index case is not only clinically important but also cost-effective and cost-saving. Sensitivity analysis supported the model's robustness, suggesting its generalization.

RESUMO

OBJECTIVES: While highly effective in preventing SARS-CoV-2 spread, national lockdowns come with an enormous economic price. Few countries have adopted an alternative "testing, tracing, and isolation" approach to selectively isolate people at high exposure risk, thereby minimizing the economic impact. To assist policy makers, we performed a cost-effectiveness analysis of these 2 strategies. METHODS: A modified Susceptible, Exposed, Infectious, Recovered, and Deceased (SEIRD) model was employed to assess the situation in Israel, a small country with ∼9 million people. The incremental cost-effectiveness ratio (ICER) of these strategies as well as the expected number of infected individuals and deaths were calculated. RESULTS: A nationwide lockdown is expected to save, on average, 274 (median 124, interquartile range: 71-221) lives compared to the "testing, tracing, and isolation" approach. However, the ICER will be, on average, $45 104 156 (median $49.6 million, interquartile range: 22.7-220.1) to prevent 1 case of death. CONCLUSION: A national lockdown has a moderate advantage in saving lives with tremendous costs and possible overwhelming economic effects. These findings should assist decision makers dealing with additional waves of this pandemic.

RESUMO

PURPOSE: The value of parotidectomy in older patients is unclear. This study presents a decision model to help resolve this question. MATERIALS & METHODS: A Markov model with Monte Carlo simulation was used to compare outcomes in patients of different ages with pleomorphic adenoma of the parotid gland treated by surgery or surveillance. RESULTS: In 30-year-old patients, surgery conferred a 3.5-year gain in life expectancy whereas in 75-year-olds, it was only 0.74 months. The expected rate of malignant transformation at age 30 years was 6.5% after surgery and 26.5% after surveillance; at age 65, corresponding rates were 0.8% and 10.7%. Sensitivity analysis showed that age was the only parameter that significantly contributed to life expectancy. The benefit of surgery was restricted in older patients. CONCLUSION: Our Markov decision-analysis model suggests that patients older than 65 years with pleomorphic adenoma have a limited survival advantage with surgery compared to surveillance.

RESUMO

With the growing technical ease and reduction in genetic screening costs, whole population BRCA screening may be a feasible option. Our objective was to investigate the cost effectiveness of whole population screening for BRCA mutations in Israel, for varying degrees of BRCA carrier state. Lifetime costs of whole female population screening for BRCA mutation carrier state versus nonscreening were compared using a Markovian process decision analysis model. Model parameters including ovarian and breast cancer risks were obtained from previously published data. Screening and other treatment-related costs were received from the Israeli Ministry of Health pricing list according to specified codes. Quality-adjusted life years were used for cost-effectiveness analysis. Sensitivity analysis was conducted to evaluate model uncertainties, specifically varying degrees of BRCA prevalence. Results show that whole population BRCA screening in Israel is cost effective across a wide range of BRCA prevalence rates with an incremental cost-effectiveness ratio of 81,493 new Israeli Shekels for a BRCA prevalence of 2.5%, increasing to 250,000 new Israeli Shekels for a 0.75% prevalence rate, per quality-adjusted life year gained. Discount rate and population BRCA prevalence and rate of risk reduction salpingo-oophorectomy are the most influential parameters in the model. Whole population screening for BRCA mutations should be offered as part of general health screening strategies by national medical insurance providers, even for non-Ashkenazi Jews. Our algorithm can be applied for other countries, adjusting local costs of screening and treatment. PREVENTION RELEVANCE: Whole population BRCA mutation screening in Israel is cost effective across a wide prevalence rate and should be offered as part of general health screening strategies by national medical insurance providers for cancer prevention.

RESUMO

OBJECTIVE: To formulate a decision analysis model based on recently published data that addresses the dilemma, whether improvement in quality of life rationalises continued proton pump inhibitors (PPI) use despite the risk of gastric cancer (GC) in patients with functional dyspepsia (FD). DESIGN: A Markov model consisting of an initial decision regarding treatment with PPI (denoting it by PPI strategy) or any other treatment without PPI (denoting it by placebo strategy) was designed. DATA SOURCES: Data from prospective cross-sectional studies indicating risk stratification for GC after the use of PPI, combined with a Markov model that comprised the following states: Live, GC stages 1-4, Death. OUTCOME MEASURES: The primary outputs included quality-adjusted life years (QALYs) and life expectancy (LE). The improvement in utility in FD without PPI as compared with PPI use was tested (PPI vs placebo strategies). Sensitivity analyses were performed to evaluate the robustness of the model and address uncertainty in the estimation of model parameters. SETTING: We considered only patients whose symptoms were relieved with PPIs and thus, had a better quality of life compared with patients who did not receive PPIs. RESULTS: The base case model showed that PPIs compared with placebo decreased LE by 58.4 days with a gain of 2.1 QALY. If utility (quality of life of patients with FD using PPI compared with patients with FD without PPI) improved by more than 0.8%, PPI use is considered better than placebo. Older patients benefited less from PPI treatment than did younger patients. CONCLUSION: To bridge the gap between evidence and decision making, we found that even a small improvement in the QALY justified continuing PPI treatment.

RESUMO

BACKGROUND: Surgery is the preferred option for patients with symptomatic localized fibrostenotic ileocecal Crohn's disease (CD) but not for those with predominantly active inflammation without obstruction. The benefit of early surgery in patients with a limited nonstricturing ileocecal CD over biologic treatment is still a debate. OBJECTIVE: Our objective is to formulate a decision analysis model based on recently published data to explore whether early surgery in patients with limited nonstricturing CD is preferred over biologic treatment. METHODS: We constructed a Markov model comparing 2 strategies of treatment: (1) early surgery vs (2) biologic treatment. To estimate the quality-adjusted life years (QALYs) and the costs in each strategy, we simulated 10,000 virtual patients with the Markov model using a Monte Carlo simulation 100 times. Sensitivity analyses were performed to evaluate the robustness of the model and address uncertainties in the estimation of model parameters. RESULTS: The costs were $29,457 ± $407 and $50,382 ± $525 (mean ± SD) for early surgery strategy and biologic treatment strategy, respectively. The QALY was 6.24 ± 0.01 and 5.81 ± 0.01 for early surgery strategy and biologic treatment strategy, respectively. CONCLUSION: The strategy of early surgery dominates (higher QALY value [efficacy] and less cost) compared with the strategy of biologic treatment in patients with limited ileocecal CD.

RESUMO

BACKGROUND AND AIMS: The multi-kinase inhibitor sorafenib is a first-line drug for patients with advanced hepatocellular carcinoma (HCC). Treatment options for patients whose disease has progressed on sorafenib are limited. In a recent randomized controlled trial (CELESTIAL trial), patients with advanced HCC who had failed prior systemic therapy had moderate progression-free survival and overall survival advantages when treated with the multi-kinase inhibitor cabozantinib. However, since this treatment is costly and is accompanied by significant adverse events in a large proportion of patients, its cost-effectiveness in these patients should be determined. METHODS: We developed a Markov model incorporating health outcomes, measured by life-years and quality-adjusted life-years (QALYs) to evaluate the cost-effectiveness of cabozantinib compared with placebo in patients who have failed prior systemic therapy. RESULTS: Treatment with cabozantinib results in a mean gain of 11.6 weeks of life (0.22 life-years) as compared with placebo. When quality of life was incorporated, treatment with cabozantinib produced a gain of 0.16 QALYs. The total mean incremental cost of cabozantinib was US$76,406 per patient. The incremental cost-effectiveness ratio for cabozantinib compared with best supportive care was US$469,374/QALY using the recommended dose of 60 mg cabozantinib daily. CONCLUSION: Our results suggest that the use of cabozantinib in patients with advanced HCC who have progressed on prior treatment, results in a modest incremental benefit with high incremental costs, suggesting that it is not cost-effective at conventional willingness to pay thresholds.

RESUMO

BACKGROUND: In Israel, coronary heart disease mortality rates are significantly higher among the Arab population than the Jewish population. Dyslipidemia prevention should begin in childhood. OBJECTIVES: To identify sociodemographic disparities in the preventive health measurement of lipid profile testing and lipoprotein levels among Israeli children and adolescents. METHODS: A cross-sectional analysis of 1.2 million children and adolescents insured by Clalit Health Services between 2007 and 2011 was conducted using sociodemographic data and serum lipid concentrations. RESULTS: Overall, 10.1% individuals had undergone lipid testing. Those with male sex (odds ratio [OR] = 0.813, 95% confidence interval [95%CI] 0.809-0.816), Arab ethnicity (OR = 0.952, 95%CI 0.941-0.963), and low socioeconomic status (SES) (OR = 0.740, 95%CI 0.728-0.752) were less likely to be tested. By 2010, differences among economic sectors narrowed and Arab children were more likely to be tested (OR = 1.039, 95%CI 1.035-1.044). Girls had higher total cholesterol, triglyceride, low-density lipoprotein-cholesterol, and non-high-density lipoprotein-cholesterol levels compared to boys (P < 0.001). Jewish children had higher cholesterol and low-density and high-density lipoprotein-cholesterol, as well as lower triglyceride levels than Arabs (P < 0.001). Children with low SES had lower cholesterol, low-density and high-density lipoprotein-cholesterol, and non-high-density lipoprotein-cholesterol levels (P < 0.001). CONCLUSIONS: We found that boys, Arab children, and those with low SES were less likely to be tested. Over time there was a gradual reduction in these disparities. Publicly sponsored healthcare services can diminish disparities in the provision of preventive health among diverse socioeconomic groups that comprise the national population.

RESUMO

BACKGROUND: The treatment paradigm of advanced renal cell carcinoma (RCC) has changed rapidly in recent years. In first-line treatment of intermediate- to poor-risk patients, the CheckMate 214 study demonstrated a significant survival advantage for nivolumab and ipilimumab versus sunitinib. The high cost of combined immune-modulating agents warrants an understanding of the combination's value by considering both efficacy and cost. The objective of this study was to estimate the cost-effectiveness of nivolumab and ipilimumab compared with sunitinib for first-line treatment of intermediate- to poor-risk advanced RCC from the U.S. payer perspective. MATERIALS AND METHODS: A Markov model was developed to compare the costs and effectiveness of nivolumab and ipilimumab with those of sunitinib in the first-line treatment of intermediate- to poor-risk advanced RCC. Health outcomes were measured in life-years and quality-adjusted life-years (QALYs). Drug costs were based on Medicare reimbursement rates in 2017. We extrapolated survival beyond the trial closure using Weibull distribution. Model robustness was addressed in univariable and probabilistic sensitivity analyses. RESULTS: The total mean cost per-patient of nivolumab and ipilimumab versus sunitinib was $292,308 and $169,287, respectfully. Nivolumab and ipilimumab generated a gain of 0.978 QALYs over sunitinib. The incremental cost-effectiveness ratio (ICER) for nivolumab and ipilimumab was $125,739/QALY versus sunitinib. CONCLUSION: Our analysis established that the base case ICER in the model for nivolumab and ipilimumab versus sunitinib is below what some would consider the upper limit of the theoretical willingness-to-pay threshold in the U.S. ($150,000/QALY) and is thus estimated to be cost-effective. IMPLICATIONS FOR PRACTICE: This article assessed the cost-effectiveness of nivolumab and ipilimumab versus sunitinib for treatment of patients with intermediate- to poor-risk metastatic kidney cancer, from the U.S. payer perspective. It would cost $125,739 to gain 1 quality-adjusted life-year with nivolumab and ipilimumab versus sunitinib in these patients.

RESUMO

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer related deaths. Patients with advanced HCC are treated with sorafenib. A recent randomized controlled trial demonstrated a survival benefit for regorafenib treatment in patients with advanced HCC who had progressed on sorafenib. We aimed to evaluate the cost-effectiveness of this approach. METHODS: To evaluate the cost effectiveness of regorafenib, we used a Markov model that incorporates health outcomes, measured by life-years and quality-adjusted life-years (QALYs). Drug costs were based on 2017 discounted prices. Model robustness was validated by probabilistic sensitivity analyses using Monte Carlo simulations. RESULTS: The use of regorafenib results in a gain of 19.76 weeks of life (0.38 Life Years) as compared to placebo. When adjusted for quality of life, using regorafenib produced a gain of 0.25 quality adjusted life years (QALYs). The incremental cost-effectiveness ratio for regorafenib compared with best supportive care was between $201,797 and $268,506 per QALY. CONCLUSION: The modest incremental benefit at a relatively high incremental cost of regorafenib treatment suggests that it is not cost-effective at commonly accepted willingness to pay thresholds.

RESUMO

BACKGROUND: Immune-modulating drugs have recently been introduced to the second-line setting of advanced bladder cancer. Pembrolizumab increases overall survival and is associated with less toxicity compared with chemotherapy in this setting based on the Keynote 045 study. The high cost of immunotherapy necessitates an assessment of its value by considering both efficacy and cost. OBJECTIVE: To estimate the cost-effectiveness of pembrolizumab for the second-line treatment of advanced bladder cancer from the perspective of payers in multiple countries. DESIGN, SETTING, AND PARTICIPANTS: We developed a Markov model to compare the cost and effectiveness of pembrolizumab with those of chemotherapy in the second-line treatment of advanced bladder cancer based on the Keynote 045 study. Drug costs were acquired for the United States (US), United Kingdom (UK), Canada, and Australia. All costs were converted from local currency to US dollars at the exchange rates in September 2017. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Health outcomes were measured in quality-adjusted life-years (QALYs). RESULTS AND LIMITATIONS: Pembrolizumab generated a gain of 0.36-0.37 QALYs compared with chemotherapy. Our analysis established the following incremental cost-effectiveness ratios (ICERs) for pembrolizumab versus chemotherapy in second-line advanced bladder cancer treatment: US $122 557/QALY; UK $91 995/QALY; Canada $90 099/QALY; and Australia $99 966/QALY. The willingness-to-pay (WTP) thresholds per QALY are considered to be around 100 000-150 000 US dollars for the US, 20 000-50 000 pounds for the UK (US$25 000-65 000), 20 000-100 000 CAD for Canada (US$16 000-80 000), and 40 000-75 000 AUD for Australia (US$32 000-60 000). CONCLUSIONS: Cost-effectiveness and WTP thresholds vary between countries. Compared with the other countries examined, US drug prices were found to be the highest, leading to the highest ICER. With standard WTP thresholds, pembrolizumab may be considered cost-effective in the US but not in the other countries examined. PATIENT SUMMARY: This article assessed the cost-effectiveness of pembrolizumab for the treatment of patients with metastatic bladder cancer who had previously failed one treatment regimen. It would cost $122 557 in the United States, $91 995 in the United Kingdom, $90 099 in Canada, and $99 966 in Australia to gain one quality-adjusted life-year with pembrolizumab versus chemotherapy in these patients, which may be considered cost-effective only in the United States because of the differences in willingness-to-pay thresholds.
