Introduction Direct thrombin inhibitors (DTI) reduce bleeding and are cost-saving in patients (pts) undergoing PCI when compared to unfractionated heparin (UFH) plus routine glycoprotein IIb/IIIa inhibition (GPI). Little is known about the cost-effectiveness of DTI alone vs. UFH alone, however. Methods We combined data on patient-level bleeding risk with several external data sources to estimate the economic impact of substituting DTI for UFH among unselected PCI patients. We used a validated model to predict the risk of major bleeding for 81,628 NCDR® CathPCI Registry® patients who received UFH only in 2004-06. DTI costs were estimated based on current FDA dosing guidelines and acquisition costs. The cost of major bleeding ($8722) was estimated based on data from the Mid America Heart Institute. The benefit of DTI vs. UFH alone was based on bleeding risk reduction from ISAR-REACT 3. A Markov model based on published data was used to estimate the loss in life expectancy associated with major bleeding. Results The overall rate of major bleeding in the reference population was 2.2%, the estimated cost of a major bleed was $8722, projected DTI costs were $641/pt and heparin costs were negligible ($4). Assuming that DTI use reduces the risk of bleeding by 33%, use of DTI for all patients was estimated to increase costs by $573/patient and was cost saving only for patients with a predicted risk of major bleeding >20% (0.16% of the overall population). When life years lost due to bleeding were included, at willingness-to-pay thresholds of $50K and $100K per life year gained, DTI was cost effective for patients with a bleeding risk ≥8% (2.5% patients) and ≥5% (7.9% of patients), respectively. Conclusions For patients undergoing PCI, substitution of DTI for UFH monotherapy is projected to increase costs for virtually all patients, but may be reasonably cost-effective for patients with a high predicted risk (≥5%) of bleeding.

ABSTRACT Background Adults with short bowel syndrome have a high mortality and significant morbidity due to unsuccessful attempts at rehabilitation that necessitate chronic use of parenteral nutrition (PN). Teduglutide is a novel therapy that promotes intestinal adaptation to improve rehabilitation but with a price >$400,000/y. Objective The current study evaluated the cost-effectiveness of using teduglutide in US adult patients with short bowel syndrome. Methods A Markov model evaluated the costs (in US dollars) and effectiveness (in quality-adjusted life years, or QALYs) of treatment compared with no teduglutide use, with a presumed starting age of 40 y. Parameters were obtained from published data or estimation. The primary effect modeled was the increased likelihood of reduced PN days per week when using teduglutide, leading to greater quality of life and lower PN costs. Sensitivity analyses were performed on all model parameters. Results In the base scenario, teduglutide cost $949,910/QALY gained. In 1-way sensitivity analyses, only reducing teduglutide cost decreased the cost/QALY gained to below the typical threshold of $100,000/QALY gained. Specifically, teduglutide cost would need to be reduced by >65% for it to reach the threshold value. Probabilistic sensitivity analysis favored no teduglutide use in 80% of iterations at a $100,000/QALY threshold. However, teduglutide therapy was cost-saving in 13% of model iterations. Conclusions Teduglutide does not meet a traditional cost-effectiveness threshold as treatment for PN reduction in adult patients with short bowel syndrome compared with standard intestinal rehabilitation. Subpopulations that demonstrate maximum benefit could be cost-saving, and complete nonuse could lead to financial loss. Teduglutide becomes economically reasonable only if its cost is substantially reduced.

AbstractDual antiplatelet therapy (DAPT) with clopidogrel plus aspirin within 48 h of acute minor strokes and transient ischemic attacks (TIAs) has been indicated to effectively reduce the rate of recurrent strokes. However, the efficacy of clopidogrel has been shown to be affected by cytochrome P450 2C19 (CYP2C19) polymorphisms. Patients carrying loss-of-function alleles (LoFAs) at a low risk of recurrence (ESRS < 3) cannot benefit from clopidogrel plus aspirin at all and may have an increased bleeding risk. In order to optimize antiplatelet therapy for these patients and avoid the waste of medical resources, it is important to identify the subgroups that genuinely benefit from DAPT with clopidogrel plus aspirin through CYP2C19 genotyping. This study sought to assess the cost-effectiveness of CYP2C19 genotyping to guide drug therapy for acute minor strokes or high-risk TIAs in China. A decision tree and Markov model were constructed to evaluate the cost-effectiveness of CYP2C19 genotyping. We used a healthcare payer perspective, and the primary outcomes included quality-adjusted life years (QALYs), costs and the incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed to evaluate the robustness of the results. CYP2C19 genotyping resulted in a lifetime gain of 0.031 QALYs at an additional cost of CNY 420.13 (US$ 59.85), yielding an ICER of CNY 13,552.74 (US$ 1930.59) per QALY gained. Probabilistic sensitivity analysis showed that genetic testing was more cost-effective in 95.7% of the simulations at the willingness-to-pay threshold of CNY 72,100 (GDP per capita, US$ 10,300) per QALY. Therefore, CYP2C19 genotyping to guide antiplatelet therapy for acute minor strokes and high-risk TIAs is highly cost-effective in China.

Background: End-stage renal disease has been imposing a heavy economic burden on public health; however, few studies have been performed on the cost-effectiveness of dialysis modalities. We aim to estimate the cost-effectiveness of different dialysis modalities in China. Methods: Cost-effectiveness analyses were performed using Markov models based on published data of hemodialysis (HD) and peritoneal dialysis (PD) modalities in China. Sensitivity analyses were conducted to identify key variables influencing the results. Results: Over a 10-year time horizon, the base-case cost-effectiveness analysis indicated that PD-first absolutely dominated the HD-first option by gaining 0.13 more quality-adjusted life years (QALYs) and costing RMB ¥81,081 less. When using reported mortality of HD and PD from the United States, the PD-first option still dominated HD-first with higher QALYs and lower costs. Sensitivity analyses revealed that the results were more sensitive to the direct cost of HD, utility of HD, utility of PD, direct cost of PD, PD mortality, and HD mortality, while less sensitive to the indirect costs and transition probabilities. The HD utility needed to be at least 0.148 higher than PD utility for HD to be cost-effective. PD was about 72% likely to be considered cost-effective compared with HD, regardless of the willingness-to-pay for QALYs. Conclusion: PD appears to be more cost-effective than HD in China, and the major influential factors on the cost-effectiveness are the direct costs of HD, utility of HD, utility of PD, direct costs of PD, PD mortality, and HD mortality.

ObjectivesTransjugular intrahepatic portosystemic stent shunt (TIPSS) is clinically effective in variceal bleeding and refractory ascites; however, the cost-effectiveness of TIPSS has yet to be evaluated in the UK. This study aimed to establish the cost-effectiveness of (i) pre-emptive TIPSS versus endoscopic band ligation (EBL) in populations with variceal bleeding and (ii) TIPSS versus large volume paracentesis (LVP) in refractory ascites.MethodsA cost-utility analysis was conducted with the perspective including healthcare costs and quality-adjusted life years (QALYs). A Markov model was constructed with a 2-year time horizon, health states for mortality and survival and probabilities for the development of variceal bleeding, ascites and hepatic encephalopathy. A survival analysis was conducted to extrapolate 12-month to 24-month mortality for the refractory ascites indication. Uncertainty was analysed in deterministic and probabilistic sensitivity analyses.ResultsTIPSS was cost-effective (dominant) and cost saving for both indications. For variceal bleeding, pre-emptive TIPSS resulted in 0.209 additional QALYs, and saved £600 per patient compared with EBL. TIPSS had a very high probability of being cost-effective (95%) but was not cost saving in scenario analyses driven by rates of variceal rebleeding. For refractory ascites, TIPSS resulted in 0.526 additional QALYs and saved £17 983 per patient and had a 100% probability of being cost-effective and cost saving when compared with LVP.ConclusionsTIPSS is a cost-effective intervention for variceal bleeding and refractory ascites. TIPSS is highly cost-saving for refractory ascites. Robust randomised trial data are required to confirm whether pre-emptive TIPSS is cost saving for variceal bleeding.

Bacillus Calmette–Guerin (BCG), the only available vaccine for tuberculosis (TB), has been applied for decades. The Indonesian government recently introduced a national TB disease control programme that includes several action plans, notably enhanced vaccination coverage, which can be strengthened through underpinning its favourable cost-effectiveness. We designed a Markov model to assess the cost-effectiveness of Indonesia’s current BCG vaccination programme. Incremental cost-effectiveness ratios (ICERs) were evaluated from the perspectives of both society and healthcare. The robustness of the analysis was confirmed through univariate and probabilistic sensitivity analysis (PSA). Using epidemiological data compiled for Indonesia, BCG vaccination at a price US$14 was estimated to be a cost-effective strategy in controlling TB disease. From societal and healthcare perspectives, ICERs were US$104 and US$112 per quality-adjusted life years (QALYs), respectively. The results were robust for variations of most variables in the univariate analysis. Notably, the vaccine’s effectiveness regarding disease protection, vaccination costs, and case detection rates were key drivers for cost-effectiveness. The PSA results indicated that vaccination was cost-effective even at US$175 threshold in 95% of cases, approximating the monthly GDP per capita. Our findings suggest that this strategy was highly cost-effective and merits prioritization and extension within the national TB programme. Our results may be relevant for other high endemic low- and middle-income countries.

Objective To compare the cost-effectiveness of sialendoscopy with gland excision for the management of submandibular gland sialolithiasis. Study Design Cost-effectiveness analysis. Setting Outpatient surgery centers. Methods A Markov decision model compared the cost-effectiveness of sialendoscopy versus gland excision for managing submandibular gland sialolithiasis. Surgical outcome probabilities were found in the primary literature. The quality of life of patients was represented by health utilities, and costs were estimated from a third-party payer’s perspective. The effectiveness of each intervention was measured in quality-adjusted life-years (QALYs). The incremental costs and effectiveness of each intervention were compared, and a willingness-to-pay ratio of $150,000 per QALY was considered cost-effective. One-way, multivariate, and probabilistic sensitivity analyses were performed to challenge model conclusions. Results Over 10 years, sialendoscopy yielded 9.00 QALYs at an average cost of $8306, while gland excision produced 8.94 QALYs at an average cost of $6103. The ICER for sialendoscopy was $36,717 per QALY gained, making sialendoscopy cost-effective by our best estimates. The model was sensitive to the probability of success and the cost of sialendoscopy. Sialendoscopy must meet a probability-of-success threshold of 0.61 (61%) and cost ≤$11,996 to remain cost-effective. A Monte Carlo simulation revealed sialendoscopy to be cost-effective 60% of the time. Conclusion Sialendoscopy appears to be a cost-effective management strategy for sialolithiasis of the submandibular gland when certain thresholds are maintained. Further studies elucidating the clinical factors that determine successful sialendoscopy may be aided by these thresholds as well as future comparisons of novel technology.

Background: Cladribine tablets are the foremost oral immune-reconstitution therapy for high disease activity relapsing multiple sclerosis (HDA-RMS). We aimed to assess the cost-effectiveness of cladribine tablets compared to natalizumab in patients with HDA-RMS in Iran. Methods: A 5-year cohort-based Markov model was developed with 11 expanded disability status score (EDSS) health states, including patients with HDA-RMS as on and off-treatment. All costs were identified from the literature and expert opinion and were measured in Iranian Rial rates, changed to the 2020 USD rate and were discounted by 7.2%. Quality adjusted life years (QALY), discounted by 3.5%, and life years gained (LYG) were adopted to measure efficacy. The final results were presented as incremental cost-effectiveness ratio that was compared to a national willingness to pay (WTP) threshold of 1 to 3 gross domestic product (GDP) per capita. Deterministic and probabilistic sensitivity analyses (D/PSA) were employed to evaluate uncertainty. Results: Cladribine tablets dominated natalizumab and yielded 6,607 USD cost-saving and 0.003 additional QALYs per patient. LYG was comparable. The main cost component was drug acquisition cost in both arms. DSA indicated the sensitivity of the results to the cost discount rates and also the patients’ body weight; while they were less sensitive to the main clinical variables. PSA indicated that cladribine tablets were cost-effective in Iran, with a probability of 57.5% and 58.6% at lower and higher limits of threshold, respectively. Conclusion: Cladribine tablets yielded higher QALYs and lower costs compared to natalizumab, in patients with HDA-RMS in Iran.

Background:The rising trend in the prevalence of obesity has during the past decades become a major public health concern in many countries, as obesity may lead to comorbidities and death. A frequent used marker for obesity is the Body Mass Index (BMI). The cost of treatment for obesity related diseases has become a heavy burden on national health care budget in many countries. While diet and exercise are the cornerstones of weight management, pharmaco­therapy is often needed to achieve and maintain desired weight loss.  In some cases of extreme obesity, bariatric surgery may be recommended. It is expected to increase by 50% in Sweden.Objective: The overall objective was to develop a cost-effectiveness model using the best available evidence to assess the cost-effectiveness of gastric bypass (GBP) surgical treatments for obesity in adult patients, in comparison with conventional treatment (CT), in Sweden from a healthcare perspective. With the model we also seeked to identify the lower cut-off point using BMI criteria, for the surgical intervention to be cost-effective. Methods:A micro-simulation model with an underlying Markov methodology was developed, that simulates individual patients. It simulates the outcomes of the patients in terms of treatment costs, life years, and quality adjusted life years (QALY) over his/her remaining lifetime. The costs are presented in SEK in the year 2006 price level (1 SEK ≈ 0.11 EUR ≈ 0.14 USD).Results: We estimated that the incremental cost per QALY gained will not exceed SEK 33,000 per QALY in patients with BMI < 35. In patients with BMI > 35 kg/m2, gastric bypass surgery has lower costs compared to conventional treatment. Conclusion: Gastric bypass surgery is a cost-effective intervention compared to conventional treatment consisting of watchful waiting, diet and exercise.

Abstract Drowning is the leading cause of death among children 12-59 months old in rural Bangladesh. This study evaluated the cost-effectiveness of a large-scale crèche intervention in preventing child drowning. Estimates of the effectiveness of the crèches was based on prior studies and the program cost was assessed using monthly program expenditures captured prospectively throughout the study period from two different implementing agencies. The study evaluated the cost-effectiveness from both a program and societal perspective. Results showed that from the program perspective the annual operating cost of a crèche was $416.35 (95%C.I.: $222 to $576), the annual cost per child was $16 (95%C.I.: $9 to $22) and the incremental-cost-effectiveness ratio (ICER) per life saved with the crèches was $17,803 (95%C.I.: $9,051 to $27,625). From the societal perspective (including parents time valued) the ICER per life saved was -$176,62 (95%C.I.: -$347,091 to -$67,684)—meaning crèches generated net economic benefits per child enrolled. Based on the ICER per disability-adjusted-life years averted from the societal perspective (excluding parents time), $2,020, the crèche intervention was cost-effective even when the societal economic benefits were ignored. Based on the evidence, the creche intervention has great potential for reducing child drowning at a cost that is reasonable.

Purpose. Five years of bisphosphonate treatment have proven efficacy in reducing fractures. Concerns exist that long-term bisphosphonate treatment may actually result in an increased number of fractures. This study evaluates, in the context of England and Wales, whether it is cost-effective to conduct a randomized controlled trial (RCT) and what sample size may be optimal to estimate the efficacy of bisphosphonates in fracture prevention beyond 5 years. Method. An osteoporosis model was constructed to evaluate the cost-effectiveness of extending bisphosphonate treatment from 5 years to 10 years. Two scenarios were run. The 1st uses long-term efficacy data from published literature, and the 2nd uses distributions elicited from clinical experts. Results of a proposed RCT were simulated. The expected value of sample information technique was applied to calculate the expected net benefit of sampling from conducting such an RCT at varying levels of participants per arm and to compare this with proposed trial costs. Results. Without further information, the better duration of bisphosphonate treatment was estimated to be 5 years using the published data but 10 years using the elicited expert opinions, although in both cases uncertainty was substantial. The net benefit of sampling was consistently high when between 2000 and 5000 participants per arm were recruited. Conclusions. An RCT to evaluate the long-term efficacy of bisphosphonates in fracture prevention appears to be cost-effective for informing decision making in England and Wales.
