Cost-Effectiveness of Hypoglossal Nerve Stimulation for Pediatric Severe Obstructive Sleep Apnea in Down Syndrome Patients.

To examine the cost-effectiveness of hypoglossal nerve stimulation (HGNS) implantation at an early age in simulated pediatric cohorts with Down Syndrome (DS) and severe obstructive sleep apnea (OSA). Cost-utility analysis. Hypothetical cohort. A Markov model simulated 3 pediatric cohorts with DS and OSA beginning at age 4 years until 21 years. Cohorts received HGNS implants in early childhood, late childhood, or adulthood at age 4, 13 (current FDA-approved age), or 18 years, respectively. Input model parameters were obtained from the literature and our institution. Outcomes were measured with an incremental cost-effectiveness ratio (ICER), measured in dollars per quality-adjusted life-year (QALY). Deterministic 1-way sensitivity analyses were conducted to evaluate the effects of parameter uncertainty. Results (total costs; total QALYs) across the time horizon were determined for each cohort: early implantation ($83,300.35; 15.79), late ($48,319.09; 14.98), and adult ($38,721.07; 14.55). ICERs were $48,892.47 per QALY for early vs late implantation, $43,471.15 per QALY for early vs adult implantation, and $30,959.58 per QALY for late vs adult implantation. All ICERs were below a willingness-to-pay threshold of $50,000 per QALY. Varying the discount rate and utility expectedly varied the ICERs and cost-effectiveness. Threshold analysis showed early implantation to be cost-effective for a HGNS implantation cost up to $62,230 compared to late implantation. The current study suggests HGNS is a cost-effective treatment strategy for pediatric patients with DS and severe OSA. Our findings also suggest cost-effectiveness at ages younger than 13, the current age of FDA approval.

An early economic evaluation of WireSafe™ to prevent guidewire retention in central venous catheter procedures

Background Guidewire retention (GWR) poses a patient safety risk during Central Venous Catheter (CVC) insertions and is listed as a ‘Never Event’ by the National Health Service England (NHSE). WireSafe™ is an intervention to prevent GWR, but its cost-effectiveness is uncertain. This study is an early economic evaluation comparing WireSafe™ to standard care from a UK healthcare perspective. Methods We conducted (i) a primary analysis of GWR related NHSE Never Events data in England between 2016 and 2020; and (ii) a cost-utility analysis, including healthcare costs and quality-adjusted life years (QALYS) for populations receiving CVC-insertions. We applied a cost-effectiveness threshold of £30,000 per QALY and considered three WireSafe™ costing scenarios (£18.50, £4.50, and £2.50). Results NHSE Never Events data showed 61 GWR cases, averaging 1 per month. Most incidents (92%) were identified during hospital stays, with one serious adverse outcome reported (peri-arrest). In a population of 200,000, we estimate WireSafe™ would prevent 59.92 wire retentions, 5.61 procedural adverse events, 0.3 cardiac adverse events, and 0.19 deaths, improving QALYs by 4.87. In the base case analysis WireSafe™ was not cost-effective and had an economically justifiable price of £2.44. There were high levels of uncertainty in the lowest cost-scenario (ICER 95% credible interval: Dominant; £793,398). Conclusions The health benefits of WireSafe™ are limited due to low GWR rates and high identification rates, making WireSafe™ viable only at low costs. Future research should prioritise obtaining more precise estimates of these parameter values which are key determinants of cost-effectiveness.

Cost-Utility Analysis of Low-Dose Pioglitazone in a Population With Prediabetes and a History of Stroke or Transient Ischemic Attack.

Pioglitazone significantly reduces the risk of stroke in people with diabetes, and in those with prediabetes, it markedly reduces the risk of stroke/myocardial infarction and new-onset diabetes. Low-dose pioglitazone provides most of the clinical benefits of high-dose pioglitazone, with fewer adverse effects. We report an economic evaluation of the cost-effectiveness of low-dose pioglitazone versus placebo from a Canadian public payer perspective in 2023 Canadian dollars. A Markov model was developed at a lifetime horizon with an annual cycle length and 5 health states (event-free, myocardial infarction, stroke, new-onset diabetes, and death). Transition probabilities were extracted from the IRIS (Insulin Resistance Intervention in Stroke) trial. Health state costs and utilities were based on public sources. Annual discount rates of 1.5% were applied in the reference-case analysis. Probabilistic analyses were conducted to deal with parameter uncertainty through 5000 simulations. The costs were estimated as $24 887 (interquartile range [IQR], $14 632-$41507) for low-dose pioglitazone and $57 301 (IQR, $48 730-$67368) for placebo, resulting in a cost saving of -$30 287 (IQR, -$43 374 to -$14 587) in favor of low-dose pioglitazone. Quality-adjusted life years were estimated as 25.99 (IQR, 24.56-26.81) for the low-dose pioglitazone and 19.44 (IQR, 18.68-20.13) for placebo, resulting in a difference of 6.37 (IQR, 5.07-7.36) in favor of low-dose pioglitazone. Consistent findings were observed from scenario analyses and 1-way probability sensitivity analyses. Holding across a wide range of values in modeling parameters, low-dose pioglitazone is found as the dominant strategy versus a placebo.

Cost-utility analysis of adapted problem adaptation therapy for depression in mild-to-moderate dementia caused by Alzheimer's disease: PATHFINDER randomised controlled trial.

Depression is common in people with dementia, and negatively affects quality of life. This paper aims to evaluate the cost-effectiveness of an intervention for depression in mild and moderate dementia caused by Alzheimer's disease over 12 months (PATHFINDER trial), from both the health and social care and societal perspectives. A total of 336 participants were randomised to receive the adapted PATH intervention in addition to treatment as usual (TAU) (n = 168) or TAU alone (n = 168). Health and social care resource use were collected with the Client Service Receipt Inventory and health-related quality-of-life data with the EQ-5D-5L instrument at baseline and 3-, 6- and 12-month follow-up points. Principal analysis comprised quality-adjusted life-years (QALYs) calculated from the participant responses to the EQ-5D-5L instrument. The mean cost of the adapted PATH intervention was estimated at £1141 per PATHFINDER participant. From a health and social care perspective, the mean difference in costs between the adapted PATH and control arm at 12 months was -£74 (95% CI -£1942 to £1793), and from the societal perspective was -£671 (95% CI -£9144 to £7801). The mean difference in QALYs was 0.027 (95% CI -0.004 to 0.059). At £20 000 per QALY gained threshold, there were 74 and 68% probabilities of adapted PATH being cost-effective from the health and social care and societal perspective, respectively. The addition of the adapted PATH intervention to TAU for people with dementia and depression generated cost savings alongside a higher quality of life compared with TAU alone; however, the improvements in costs and QALYs were not statistically significant.

Transcatheter aortic valve implantation with SAPIEN 3 versus surgical aortic valve replacement in patients with symptomatic severe aortic stenosis at low risk of surgical mortality: a cost-utility analysis for Switzerland.

The 2021 European Society of Cardiology Guidelines on valvular heart disease recommend transcatheter aortic valve implantation (TAVI) for patients with symptomatic severe aortic stenosis at low surgical risk and age ≥75 years who are suitable for a transfemoral approach (recommendation class IA) based on two large randomised controlled trials (PARTNER 3 and Evolut Low Risk) comparing transcatheter aortic valve implantation with surgical aortic valve replacement (SAVR). Whether such an approach is cost-effective in Switzerland remains unclear. The aim of this cost-utility analysis was to compare transcatheter aortic valve implantation with SAPIEN 3 versus surgical aortic valve replacement in symptomatic severe aortic stenosis patients at low risk of surgical mortality from the perspective of Swiss compulsory health insurance using data from the PARTNER 3 trial (reflecting specifically the safety and efficacy of the SAPIEN 3 TAVI device). A previously published two-stage Markov-based model that captured clinical outcomes from the PARTNER 3 trial was adapted from the perspective of the Swiss compulsory health insurance system, using local or geographically close general population mortality and utility data, unit costs and medical resource use from publicly available sources and based on expert opinion. The model had a lifetime horizon with a 3% yearly discounting factor. The cost-utility analysis estimated changes in both direct healthcare costs and health-related quality-adjusted life years for transcatheter aortic valve implantation compared with surgical aortic valve replacement in patients with symptomatic severe aortic stenosis at low risk of surgical mortality. Overall, transcatheter aortic valve implantation with SAPIEN 3 resulted in lifetime costs per patient of CHF 79,534 and quality-adjusted life years per patient of 9.64, compared with surgical aortic valve replacement lifetime costs and quality-adjusted life years per patient of CHF 76,891 and 8.96, respectively. Compared with surgical aortic valve replacement, transcatheter aortic valve implantation was estimated to offer an incremental improvement of +0.68 quality-adjusted life years per patient at an increased cost of +CHF 2643 per patient over a lifetime horizon. The incremental cost-effectiveness ratio was CHF 3866 per quality-adjusted life year gained and remained below CHF 50,000 per quality-adjusted life year gained across several sensitivity analyses. This analysis suggests that transcatheter aortic valve implantation using the SAPIEN 3 device is likely to be a highly cost-effective alternative for symptomatic severe aortic stenosis patients at a low risk of surgical mortality, treated in the contemporary Swiss setting. These findings may help to inform a holistic approach when making policy decisions for the management of this patient group.

Universal Health Coverage of Opioid Agonist Treatment in Norway: An Equity-Adjusted Economic Evaluation.

Detailed information on the efficiency of health services targeting opioid use disorder (OUD) and treatment with opioid agonist treatment (OAT) is sparse. Many countries, including Norway, are still falling short of universal health coverage (UHC) of OAT. This study aims to evaluate the incremental lifetime costs and effects of treating OUD with OAT as compared to no OAT in Norway and scaling up the treatment to a universal coverage level using equity-adjusted health economic evaluations. We conducted cost-utility and budget impact analyses and constructed a two-state Markov model to compare the lifetime costs and outcomes among patients with OUD with and without OAT. Model inputs were derived from routine health information systems and the literature, with costs reported in 2023 Norwegian Kroner (NOK). The analyses were conducted from a Norwegian extended health-service and societal perspectives, with a lifetime time horizon. Quality-adjusted life years (QALYs) was the metric of health benefits. Outcomes were reported as incremental cost-effectiveness ratios (ICERs). The willingness-to-pay (WTP) threshold was equity-adjusted according to the future prognostic healthy life year loss method in Norway (severity of disease criterion), which is sensitive to the size of future undiscounted healthy life year loss due to the affected conditions. The WTP threshold is NOK 825,000 per QALY gained in Norwegian policy for conditions with undiscounted future QALY loss > 20. Uncertainty in the parameters and robustness of the results were assessed with one-way and probabilistic sensitivity analyses and scenario analyses. The mean results from probabilistic sensitivity analysis estimated that OAT was associated with 3.03 additional discounted QALYs gain and incremental lifetime discounted cost of NOK 1.45 million, leading to an ICER of NOK 479,099 per QALY gained when compared with not providing OAT, with the extended health-service perspective. From a societal perspective, OAT was cost-saving, i.e. OAT produced greater health benefits while resulting in lower overall societal costs compared to no OAT. The mean undiscounted future health loss was estimated to be 21.34 QALYs for the Norwegian patient group with OUD. A total 5-year budget increase of NOK 1.208 billion was estimated if OAT was going to be scaled up from the current coverage level of 70% to UHC. Compared with the current coverage, 100% coverage of OAT was associated with an additional lifetime cost of NOK 4.332 billion but also an additional 6760 QALYs gained. Our analysis suggests that OAT is cost-effective in Norway and has the potential to be cost-saving from a societal perspective. Therefore, Norwegian policy should consider scaling up treatment to extend the coverage of OAT.

A cost-utility analysis of single maintenance and reliever (SMART) therapy as compared to step 3 fixed-dose therapy in patients aged 12 years or more with uncontrolled asthma.

A significant percentage of patients with asthma appear to benefit from the addition of long-acting β2-agonists (LABAs) to ICS to achieve better control of their disease. The aim of the present study was to determine the cost-utility of single inhaler combination inhaled ICS/LABAs as both maintenance and reliever (SMART) versus remaining at the same treatment step with fixed-dose ICS-LABA maintenance with a short-acting β2-agonist (SABA) as reliever in patients aged 12 years or more with uncontrolled asthma. A Markov-type model was developed to estimate the costs and health outcomes of a simulated cohort of patients aged 12 years or more with uncontrolled asthma treated for 12 months. The effectiveness data and transition probabilities were obtained from a recent meta-analysis. Cost data were obtained from official databases provided by the Colombian Ministry of Health. The main outcome was the variable "quality-adjusted life-years" (QALYs). The base-case analysis showed that compared with remaining at the same GINA treatment step with ICS/LABA maintenance plus SABA reliever, ICS/LABAs as SMART was associated with lower costs, US$2,906.92 versus $4,462.02 average cost per patient, and the greatest gain in QALYs, 0.8540 versus 0.8258 QALYs on average per patient, thus leading to dominance. Compared with remaining at the same GINA treatment step with ICS/LABA maintenance plus SABA reliever, ICS/LABAs as SMART is more cost-effective in patients aged 12 years or more with uncontrolled asthma. This is because ICS/LABAs as SMART showed a greater gain in QALYs at lower total treatment costs.

Protocol for a prospective randomized trial of surgical versus conservative management for unstable fractures of the distal radius in patients aged 65 years and older.

The primary aim of this study is to quantify and compare outcomes following a dorsally displaced fracture of the distal radius in elderly patients (aged ≥ 65 years) who are managed conservatively versus with surgical fixation (open reduction and internal fixation). Secondary aims are to assess and compare upper limb-specific function, health-related quality of life, wrist pain, complications, grip strength, range of motion, radiological parameters, healthcare resource use, and cost-effectiveness between the groups. A prospectively registered (ISRCTN95922938) randomized parallel group trial will be conducted. Elderly patients meeting the inclusion criteria with a dorsally displaced distal radius facture will be randomized (1:1 ratio) to either conservative management (cast without further manipulation) or surgery. Patients will be assessed at six, 12, 26 weeks, and 52 weeks post intervention. The primary outcome measure and endpoint will be the Patient-Rated Wrist Evaluation (PRWE) at 52 weeks. In addition, the abbreviated version of the Disabilities of Arm, Shoulder and Hand questionnaire (QuickDASH), EuroQol five-dimension questionnaire, pain score (visual analogue scale 1 to 10), complications, grip strength (dynamometer), range of motion (goniometer), and radiological assessments will be undertaken. A cost-utility analysis will be performed to assess the cost-effectiveness of surgery. We aim to recruit 89 subjects per arm (total sample size 178). The results of this study will help guide treatment of dorsally displaced distal radial fractures in the elderly and assess whether surgery offers functional benefit to patients. This is an important finding, as the number of elderly distal radial fractures is estimated to increase in the future due to the ageing population. Evidence-based management strategies are therefore required to ensure the best outcome for the patient and to optimize the use of increasingly scarce healthcare resources.

Cost-effectiveness analysis of valvular surgery in high- and low- to middle-income countries: A scoping review.

Global disparities in valvular surgery services exist. Cost-effectiveness analysis (CEA) and cost-utility analysis can be used to guide national investment decisions. This scoping review aims to synthesize economic evaluations for valvular surgery by income settings and provide recommendations. A systematic literature review identified primary CEAs or CUAs in English comparing surgical management strategies for valvular heart disease. MEDLINE, Embase, CINAHL, Web of Science, and Business Source Complete were searched using keywords "valvular surgery," "valve disease," "cost-effectiveness," and "cost-benefit analysis". Articles comparing outcomes or costs only were excluded. Search results were uploaded and screened on COVIDENCE. Variables from eligible articles were charted in a spreadsheet. Twenty articles were eligible, six from low- and middle-income countries (LMICs) and 14 from high-income countries (HICs). In HICs, the top conditions were degenerative aortic valve disease (7/14) and mitral valve disease (4/14) compared to congenital (2/6) and rheumatic heart diseases (2/6) in LMICs. HICs evaluated new technologies and techniques, whereas LMICs compared different valve types or surgery versus no intervention. Most articles used published studies (12/20) or databases (7/20) to conduct their CEA and quality-adjusted life years was the most common effectiveness measure (12/20). Comparator interventions were cost-effective in all LMIC articles and in 8/14 for HICs. Economic evaluations are mostly conducted in HICs and for adult conditions. More analyses in LMICs are needed. This can be facilitated by maintaining databases, documenting costs, and implementing quality of life assessments.

Cost-effectiveness and cost-utility of optimized mercaptopurine treatment versus placebo in ulcerative colitis patients: The randomized controlled OPTIC trial.

We assessed the cost-effectiveness and cost-utility of therapeutic drug monitoring (TDM)-guided mercaptopurine treatment compared with placebo in ulcerative colitis (UC) patients failing 5-aminosalicylates. Data were gathered alongside the randomized controlled OPTIC trial (EudraCT: 2015-005260-41). The evaluation was performed from a health care and societal perspective as cost-effectiveness and cost-utility analyses with a time horizon of one year. Volumes and costs of in-hospital care, out-of-hospital care, out-of-pocket expenses and productivity loss were assessed. The main outcomes were the extra costs per additional patient who achieved clinical remission and endoscopic improvement at 52weeks (responders) and extra costs per quality-adjusted life-year (QALY) gained. In total, 59 patients were randomized to the intervention (n=29) and control (n=30) group. Non-significant differences in costs were €63 (-€1267 to €1434; P=0.93) in favour of placebo from a health care perspective and -€742 (-€3683 to €2016; P=0.64) in favour of mercaptopurine from a societal perspective. The higher proportion of responders and a non-significant QALY difference of 0.0475 (-0.024-0.117) (P=0.184) favouring patients on mercaptopurine treatment resulted in €165 extra costs per additional responder and €1326 extra costs per QALY gained from a health care perspective. From a societal perspective, dominance over placebo was observed with cost savings of €1937 per additional responder and €15,621 per QALY gained. The probability of optimised mercaptopurine treatment being cost-effective was 0.80 at a willingness to pay per additional QALY of €20,000. TDM-based mercaptopurine treatment in UC patients failing 5-aminosalicylates is a cost-effective strategy from a societal perspective.

Cost-Utility Analysis of PCSK9 Inhibitors and Quality of Life: A Two-Year Multicenter Non-Randomized Study.

The primary objective of this study was to conduct a cost-utility analysis of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in real-world, comparing their use with standard care for managing cardiovascular disease. A multicenter prospective study was conducted across 12 Spanish hospitals from May 2020 to April 2022, involving 158 patients with hypercholesterolemia or atherosclerotic cardiovascular disease. This study assessed health-related quality of life (QoL) using the EQ-5D-3L questionnaire. The cost-utility analysis evaluated the economic impact of PCSK9 inhibitors when used with standard care compared to standard care alone, calculating the incremental cost-effectiveness ratio (ICER). This study included 158 patients with an average age of 61 years, male (66.5%). For patients initiating PCSK9 inhibitors, the treatment cost was EUR 13,633.39, while standard therapy cost EUR 3638.25 over two years. QoL for PCSK9 inhibitors stood at 1.6489 over two years, compared to 1.4548 for standard therapy. The results revealed favorable cost-utility outcomes, with an ICER of EUR 51,427.72. Significant improvements were observed in the domains of mobility, self-care, daily activities, pain/discomfort, and anxiety/depression (p < 0.001). This study presents the first real-world cost-utility analysis of PCSK9 inhibitors, supporting their economic rationale and highlighting their benefits in clinical practice. Healthcare decision-makers can use these results to inform their decisions and reimbursement policies concerning PCSK9 inhibitors. Trial Registration clinicaltrials.gov Identifier: NCT04319081.

Cost-utility analysis of duloxetine in osteoarthritis: from Chinese healthcare perspective

ABSTRACT Objectives To estimate the cost-utility of duloxetine compared with that of a placebo, common traditional nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors for the treatment of osteoarthritis (OA) from a Chinese healthcare perspective. Methods A Markov model was constructed. The costs and utility inputs were obtained from the database and published literature. Incremental cost-effectiveness ratio (ICER) was the main model outputs. Subgroup analyses were also conducted for patients at high risk of gastrointestinal (GI) or cardiovascular (CV) AEs. Deterministic and probabilistic sensitivity analyses were performed. Results The model estimated an ICER of $3409.21/QALY for duloxetine compared with etoricoxib, with duloxetine dominating other active treatment strategies in patients at a low risk of GI and CV AEs. The ICER for duloxetine over etoricoxib was $322.21/QALY in patients at high risk of GI and CV AEs. These results were consistent with the sensitivity analyses; 53.64% and 53.93% of the patients were willing to use duloxetine comparing with etoricoxib, for which the thresholds were 1.0 and 3.0 per capita gross domestic product (GDP), respectively. Conclusions Duloxetine is a valuable option for patients with OA; however, uncertainties exist in the model, and these suggestions can be adopted with caution.

Evaluating the benefits of emicizumab prophylaxis for haemophilia A with inhibitors: A cost-effectiveness and budget impact analysis in Thailand's upper-middle income setting.

In Thailand, an upper-middle-income country, managing haemophilia A (HA) with inhibitors poses significant challenges, often necessitating bypassing agents (BPAs) for bleeding control. This study evaluates the cost-effectiveness and budget impact of emicizumab, a novel prophylactic agent, as an alternative to both episodic and prophylactic BPA treatments from a societal perspective. A Markov model was employed to estimate the lifetime societal costs and outcomes of emicizumab prophylaxis for HA patients with inhibitors. Treatment efficacy, cost, and epidemiological data were obtained through a comprehensive literature review and incorporated into the model. A 5-year budget impact analysis complemented the cost-utility analysis, with a 3% annual discount rate applied to future costs and outcomes. In the base-case scenario, emicizumab prophylaxis in HA patients aged 2 years and above demonstrated superior cost-effectiveness, yielding 18.1 quality-adjusted life years (QALYs) per patient over a lifetime and resulting in cost savings of 138 million Thai Baht (THB) compared to BPA prophylaxis. Compared to episodic BPA treatment, emicizumab yielded 30.5 QALYs and saved 25 million THB per patient. The 5-year budget impact was projected at 1775 million THB. Emicizumab offers a cost-saving approach for HA treatment with inhibitors in Thailand, promising significant health benefits and budgetary savings. This supports its potential inclusion in Thailand's National List of Essential Medicines to enhance haemophilia care access. Managing haemophilia A (HA) with inhibitors in Thailand, an upper-middle-income country, faces challenges due to limited access to effective treatments or newer drugs for bleeding management. Emicizumab prophylaxis found to as a cost-effective and viable alternative to traditional treatments, effectively preventing bleeding in Thai HA patients over 2 years old with inhibitors. Demonstrating improved clinical outcomes and reduced costs, emicizumab prophylaxis outperforms episodic BPA treatments, positioning it as a superior treatment option for HA patients with inhibitors in Thailand.

A Nationwide Physical Activity Intervention for 654,500 Adults in Singapore: Cost-Utility Analysis.

Increasing physical inactivity is a primary risk factor for diabetes and hypertension, contributing to rising health care expenditure and productivity losses. As Singapore's aging population grows, there is an increased disease burden on Singapore's health systems. Large-scale physical activity interventions could potentially reduce the disease burden but face challenges with the uncertainty of long-term health impact and high implementation costs, hindering their adoption. We examined the cost-effectiveness of the Singapore National Steps Challenge (NSC), an annual nationwide mobile health (mHealth) intervention to increase physical activity, from both the health care provider perspective, which only considers the direct costs, and the societal perspective, which considers both the direct and indirect costs. We used a Markov model to assess the long-term impact of increased physical activity from the NSC on adults aged 17 years and older. A Monte Carlo simulation with 1000 samples was conducted to compare two situations: the NSC conducted yearly for 10 years against a no-intervention situation with no NSC. The model projected inpatient and outpatient costs and mortality arising from diabetes and hypertension, as well as their complications. Health outcomes were expressed in terms of the quality-adjusted life-years (QALYs) gained. All future costs and QALYs were discounted at 3% per annum. Sensitivity analyses were done to test the robustness of our model results. We estimated that conducting the NSC yearly for 10 years with a mean cohort size of 654,500 participants was projected to prevent 6200 diabetes cases (95% credible interval 3700 to 9100), 10,500 hypertension cases (95% credible interval 6550 to 15,200), and 4930 deaths (95% credible interval 3260 to 6930). This led to a reduction in health care costs of SGD (Singapore dollar) 448 million (95% credible interval SGD 132 million to SGD 1.09 billion; SGD 1=US $0.73 for the year 2019). There would be 78,800 (95% credible interval 55,700 to 102,000) QALYs gained. Using a willingness-to-pay threshold of SGD 10,000 per QALY gained, the NSC would be cost-saving. When indirect costs were included, the NSC was estimated to reduce societal costs by SGD 1.41 billion (95% credible interval SGD 353 million to SGD 3.80 billion). The model was most sensitive to changes in the inpatient cost of treatment for diabetes complications, time horizon, and program compliance. In this modeling study, increasing physical activity by conducting a yearly nationwide physical activity intervention was cost-saving, preventing diabetes and hypertension and reducing mortality from these diseases. Our results provide important information for decision-making in countries that may consider introducing similar large-scale physical activity programs.

Cost-utility of sirolimus in the treatment of vascular malformations.

Sirolimus is being increasingly employed to manage specific vascular anomalies. We performed an exploratory cost-utility analysis to evaluate sirolimus as a treatment for vascular malformations from the Australian healthcare system perspective. Over a one-year time horizon, sirolimus treatment was associated with an increased expenditure of AU$2832.80 and a gain of 0.08 quality-adjusted life years (QALYs) when compared to supportive care, resulting in an incremental cost-effectiveness ratio of AU$35,410/QALY. By most metrics, sirolimus would be considered a cost-effective treatment for vascular malformations.

Vein bypass first vs. best endovascular treatment first revascularisation strategy for chronic limb-threatening ischaemia due to infra-popliteal disease: the BASIL-2 RCT.

Chronic limb-threatening ischaemia with ischaemic pain and/or tissue loss. To examine the clinical and cost-effectiveness of a vein bypass-first compared to a best endovascular treatment-first revascularisation strategy in preventing major amputation or death. Superiority, open, pragmatic, multicentre, phase III randomised trial. Thirty-nine vascular surgery units in the United Kingdom, and one each in Sweden and Denmark. Patients with chronic limb-threatening ischaemia due to atherosclerotic peripheral arterial disease who required an infra-popliteal revascularisation, with or without an additional more proximal infra-inguinal revascularisation procedure, to restore limb perfusion. A vein bypass-first or a best endovascular treatment-first infra-popliteal, with or without an additional more proximal infra-inguinal revascularisation strategy. The primary outcome was amputation-free survival. Secondary outcomes included overall survival, major amputation, further revascularisation interventions, major adverse limb event, health-related quality of life and serious adverse events. Participants were randomised to a vein bypass-first or a best endovascular treatment-first revascularisation strategy. The original sample size of 600 participants (247 events) was based on a hazard ratio of 0.66 with amputation-free survival rates of 0.72, 0.62, 0.53, 0.47 and 0.35 in years 1-5 in the best endovascular treatment-first group with 90% power and alpha at p = 0.05. The sample size was revised to an event-based approach as a result of increased follow-up time due to slower than anticipated recruitment rates. Participants were followed up for a minimum of 2 years. A cost-effectiveness analysis was employed to estimate differences in total hospital costs and amputation-free survival between the groups. Additionally, a cost-utility analysis was carried out and the total cost and quality-adjusted life-years, 2 and 3 years after randomisation were used. Between 22 July 2014 and 30 November 2020, 345 participants were randomised, 172 to vein bypass-first and 173 to best endovascular treatment-first. Non-amputation-free survival occurred in 108 (63%) of 172 patients in the vein bypass-first group and 92 (53%) of 173 patients in the best endovascular treatment-first group [adjusted hazard ratio 1.35 (95% confidence interval 1.02 to 1.80); p = 0.037]. Ninety-one (53%) of 172 patients in the vein bypass-first group and 77 (45%) of 173 patients in the best endovascular treatment-first group died [adjusted hazard ratio 1.37 (95% confidence interval 1.00 to 1.87)]. Over follow-up, the economic evaluation discounted results showed that best endovascular treatment-first was associated with £1690 less hospital costs compared to vein bypass-first. The cost utility analysis showed that compared to vein bypass-first, best endovascular treatment-first was associated with £224 and £2233 less discounted hospital costs and 0.016 and 0.085 discounted quality-adjusted life-year gain after 2 and 3 years from randomisation. Recruiting patients to the Bypass versus Angioplasty in Severe Ischaemia of the Leg Trial-2 trial was difficult and the target number of events was not achieved. A best endovascular treatment-first revascularisation strategy was associated with better amputation-free survival, which was largely driven by fewer deaths. Overall, the economic evaluation results suggest that best endovascular treatment-first dominates vein bypass-first in the cost-effectiveness analysis and cost-utility analysis as it was less costly and more effective than a vein bypass-first strategy. The Bypass versus Angioplasty in Severe Ischaemia of the Leg Trial-2 investigators have a data sharing agreement with the BEst Surgical Therapy in patients with Chronic Limb threatening Ischaemia investigators. One output of this collaboration will be an individual patient data meta-analysis. Current Controlled Trials ISRCTN27728689.

Cost Analysis of Scleral Buckle and Pars Plana Vitrectomy for Retinal Detachment Surgery.

To compare the cost and utility of scleral buckle (SB) and pars plana vitrectomy (PPV) techniques for repairing moderately complex rhegmatogenous retinal detachment (RRD). A cost-utility analysis was conducted using data from the Primary Retinal Detachment Outcomes Study (PRO) and a study conducted by the author. Total costs, patient utility over a lifetime, and cost per quality-adjusted life year (QALY) were calculated for each surgical procedure. The cost of scleral buckle surgery was €287.93, with an estimated lifetime QALY of 7.49. Costs per QALY were €38.44. According to the PRO study and Belin et al, total costs were $5975, with a lifetime QALY of 5.4 and costs per QALY of $1106. The cost of pars plana vitrectomy (PPV) was €1468.26, with an estimated lifetime QALY of 6.84 and costs per QALY of €214.65. Based on the PRO study and Belin et al, total costs were $8125, with a lifetime QALY of 4.7 and costs per QALY of $2196. Repairing moderately complex RRD presents a highly cost-effective profile for both SB and PPV techniques, well below recommended QALY thresholds. SB demonstrated a slightly more favorable profile compared to PPV.

Pharmacoeconomic Aspects of Diabetes Mellitus: Outcomes and Analysis of Health Benefits Approach.

Pharmacoeconomics is an important tool for investigating and restructuring healthcare policies. In India, recent statistical studies have shown that the number of diabetic patients is rapidly increasing in the rural, middle and upper-class settings. The aim of this review is to call attention towards the need to carry out pharmacoeconomic studies for diabetes mellitus and highlight the outcome of these studies on healthcare. A well-structured literature search from PubMed, Embase, Springer, ScienceDirect, and Cochrane was done. Studies that evaluated the cost-effectiveness of various anti-diabetic agents for type 2 diabetes were eligible for inclusion in the analysis and review. Two independent reviewers sequentially assessed the titles, abstracts, and full articles to select studies that met the predetermined inclusion and exclusion criteria for data abstraction. Any discrepancies between the reviewers were resolved through consensus. By employing search terms such as pharmacoeconomics, diabetes mellitus, cost-effective analysis, cost minimization analysis, cost-utility analysis, and cost-benefit analysis, a total of 194 papers were gathered. Out of these, 110 papers were selected as they aligned with the defined search criteria and underwent the removal of duplicate entries. This review outlined four basic pharmacoeconomic studies carried out on diabetes mellitus. It gave a direction that early detection, patient counseling, personalized medication, appropriate screening intervals, and early start of pharmacotherapy proved to be a cost-effective as well as health benefits approach.

A Cost–Utility Analysis of the Use of −125 mm Hg Closed-incision Negative Pressure Therapy in Oncoplastic Breast Surgery

Background: Closed-incision negative pressure therapy (ciNPT) decreases the rate of wound complications in oncoplastic breast surgery (OBS) but at a fiscal cost. Our aim was to examine the cost-utility of ciNPT in OBS. Methods: A literature review was performed to obtain the probabilities and outcomes for the treatment of unilateral breast cancer with OBS with ciNPT versus without. Reported utility scores in the literature were used to calculate quality-adjusted life years (QALYs) for each health state. A decision analysis tree was constructed with rollback analysis to determine the more cost-effective strategy. An incremental cost–utility ratio was calculated. Sensitivity analyses were performed. Results: OBS with ciNPT is associated with a higher clinical effectiveness (QALY) of 33.43 compared to without (33.42), and relative cost increase of $667.89. The resulting incremental cost-utility ratio of $57432.93/QALY favored ciNPT. In one-way sensitivity analysis, ciNPT was the more cost-effective strategy if the cost of ciNPT was less than $1347.02 or if the probability of wound dehiscence without was greater than 8.2%. Monte Carlo analysis showed a confidence of 75.39% that surgery with ciNPT is more cost effective. Conclusion: Despite the added cost, surgery with ciNPT is cost-effective. This finding is a direct result of decreased overall wound complications with ciNPT.
