Background: Endoscopic therapies for Crohn’s disease (CD) strictures, including endoscopic balloon dilation (EBD) and endoscopic stricturotomy (ESt), are less invasive interventions compared to surgery. ESt is advantageous for strictures that are longer, more fibrotic, or adjacent to anatomic structures requiring precision, and it has shown a high rate of surgery-free survival. Methods: We designed a microsimulation state-transition model comparing ESt to surgical resection for CD strictures. We calculated quality-adjusted life years (QALYs) over a 10-year time horizon; secondary outcomes included costs (in 2022 USD) and incremental cost-effectiveness ratios (ICERs). We used a societal perspective to compare our strategies at a willingness-to-pay (WTP) threshold of 100,000 USD/QALY. Sensitivity analyses, both deterministic and probabilistic, were performed. Results: The surgery strategy cost more than 2.5 times the ESt strategy, but resulted in nine more QALYs per 100 persons. The ICER for the surgery strategy was 308,787 USD/QALY; thus, the ESt strategy was determined more cost-effective. One-way sensitivity analyses showed that quality of life after ESt as compared to that after surgery, the likelihood of repeat intervention, and surgical mortality and cost were the most influential parameters shifting cost-effectiveness. Probabilistic sensitivity analyses favored ESt in most (65.5%) iterations. Conclusions: Our study finds endoscopic stricturotomy to be a cost-effective strategy to manage primary or anastomotic Crohn’s disease strictures. Post-intervention quality of life and probabilities of requiring repeated interventions exert most influence on cost-effectiveness. The decision between ESt and surgery should be made considering patient and stricture characteristics, preferences, and cost-effectiveness. Full article

Background/Objectives: Reducing waiting times for elective surgeries remains a critical global healthcare challenge that negatively impacts patient outcomes and economic productivity. This study develops an adaptable cost-utility modeling framework for assessing the cost-effectiveness (CE) of reducing waiting time for elective surgeries in data-limited environments. Methods: We evaluated the economic and health impacts of Egypt’s recent initiative aimed at decreasing surgical waiting lists. The study conducts a CE analysis of the initiative by estimating incremental costs (expressed in Egyptian Pounds—EGP) and outcomes (expressed in quality-adjusted life years—QALYs) before and after its implementation, performs a benefit–cost analysis to quantify the initiative’s return on investment, and employs a budget share method to evaluate catastrophic health expenditure (CHE). The analysis included five elective surgical interventions: open-heart surgery, cardiac catheterization, cochlear implantation, ophthalmic surgery, and orthopedic (joint replacement) surgery. Results: The main research outcomes of the study are as follows. The initiative resulted in incremental cost-effectiveness ratios of EGP 46,795 (societal perspective) and EGP 56,094 (payer perspective) per QALY, both within acceptable CE thresholds. Most of the evaluated interventions demonstrated substantial returns on the investment. Without public funding, more than 90% of patients faced CHE, indicating considerable financial barriers to elective surgeries. Conclusions: Egypt’s initiative to reduce waiting times was deemed cost-effective. Our adaptable modeling framework could be practical for similar evaluations in low/middle-income countries, especially where data is limited. Scaling up the initiative to include additional curative and preventive services and integrating it with broader health system reforms in Egypt is strongly recommended. Full article

Spasticity is a persistent and debilitating consequence of stroke and effective rehabilitation is a healthcare priority. Botulinum neurotoxin A (BoNT-A) with supportive therapy has increasingly been embedded within clinical practice for treatment of post-stroke spasticity. But the evidence for this approach has hitherto been limited to the findings of a limited number of small trials. The InTENSE trial was undertaken specifically to provide high-quality clinical trial evidence focusing on the effect of BoNT-A and adjunctive therapy on upper limb spasticity. While the clinical trial did not detect a significant impact upon clinical outcomes, there remains a need to evaluate any impact on the broader use of healthcare resources and overall cost-effectiveness. A detailed cost–utility analysis of the InTENSE trial was undertaken. The costs over the 12-month follow-up period were compared with quality-adjusted life years (QALY) gained using utilities generated from the EQ-5D three level (EQ-5D-3L) instrument. There were no significant differences in QALY gained between the intervention and control groups identified, or in the majority of health and community care costs. The Incremental Cost-Effectiveness Ratio per QALY gained was estimated at AU $63,947.11 (Australian dollars), which is well above accepted thresholds for cost-effectiveness in Australia. The study was unable to identify evidence for the cost-effectiveness of treatment approaches combining BoNT-A with adjunctive therapy. Full article

Background/Objectives: CKD-associated pruritus (CKD-aP) is a serious systemic comorbidity occurring in patients with CKD. Despite the burden of CKD-aP, there are limited efficacious treatments available for its management; difelikefalin is the only approved treatment based on its efficacy and safety demonstrated in two clinical studies, namely KALM-1 and KALM-2. This study aimed to evaluate the cost-effectiveness of difelikefalin plus best supportive care (BSC) versus BSC alone when treating moderate-to-severe CKD-aP in patients receiving in-centre haemodialysis, from the perspective of the UK healthcare system. Methods: A de novo lifetime Markov health economic model was built to assess the cost-effectiveness of difelikefalin. The modelled efficacy of difelikefalin was based on data from KALM-1 and KALM-2 pooled at the patient level. The main efficacy driver was the total 5-D Itch scale score. Per-cycle probabilities of changing health states defined by CKD-aP severity were used to derive transition matrices; the model also estimated time-dependent annual probabilities of death and transplant for people on haemodialysis. An increased risk of mortality for modelled patients with very severe, severe, or moderate CKD-aP was applied. Health state utilities and management costs were based on published evidence. Results: Modelled patients treated with difelikefalin were estimated to have a reduced severity of CKD-aP. Consequently, difelikefalin plus BSC was associated with an increased life expectancy of 0.11 years per person and improved HRQoL compared with BSC alone. This translated to higher quality-adjusted life years, at 0.26 per person gained compared to BSC alone. Improved patient outcomes were achieved at an incremental cost of £7814 per person. Conclusions: Overall, at a price of £31.90/vial, difelikefalin was estimated to be a cost-effective treatment for moderate-to-severe CKD-aP at a willingness-to-pay threshold of £30,000/QALY, with conclusions robust to sensitivity analysis.

This study aimed to evaluate the therapeutic adherence to antiretroviral therapy (ART) and the cost of care for people living with HIV (PLwHIV) in the Condesa Specialized Clinics (CSCs). A cross-sectional observational study was conducted using the Adherence Follow-Up Questionnaire developed by The AIDS Clinical Trials Group (ACTG) to measure adherence in 261 PLwHIV. An economic Markov model was developed to simulate clinical outcomes, health costs, and quality-adjusted life years (QALYs) over a 5-year horizon from the CSC perspective. The mean adherence index was 89.97, and 59% of the surveyed PLwHIV were non-adherent, but more than 95% of the population had an undetectable viral load, suggesting that ART remains effective in achieving clinical goals, even under suboptimal adherence conditions. More than half of the surveyed PLwHIV (60.54%) stated that they had stopped taking their ART at some point, and the three most frequent causes were forgetting (49.37%), being away from home (45.57%), and having a change in their daily routine (25.95%). The economic model showed a cumulative cost per PLwHIV of USD 8432 and 3.80 QALYs (USD 2218/QALYs), which is below the threshold of willingness to pay in Mexico (USD 13,790/QALY). These findings provide valuable information to guide public health decisions and resource allocation in HIV management in Mexico. Full article

Background/Objectives: As life expectancy rises and the epidemiological landscape of chronic diseases evolves, the necessity to assess and improve the overall health status of the population becomes increasingly fundamental. Therefore, evaluating health gains is a crucial challenge for modern health systems, particularly in the context of limited resources and increasing demand for services. The aim of this study is to assess health gains and their costs, with data provided by a private Italian clinic. Methods: We conducted a retrospective study on 129 patients admitted between June 2020 and August 2023 in a solvent ward for short-term planned hospitalization. The patients completed the EQ-5D-5L questionnaire at both admission and discharge. Quality-Adjusted Life Years (QALYs) were estimated based on the difference in EQ-5D-5L scores between discharge and admission, assuming that health gains persist up to two years post-discharge. Through QALYs value and hospitalization cost, a cost–utility analysis was performed. Descriptive and statistical analyses were carried out using STATA SE/14.0 software. Results: Of the studied sample, 55% was female, the median age was 81 [11] years old, and the median length of stay (LoS) was 16 [16] days. The patients gained, in median, 0.33 [0.38] in QALY, which was higher for males (0.35 [0.34]) than females (0.29 [0.45]). The QALY gained was greater for the non-geriatric patients (0.41 [0.42]) than geriatric ones (0.32 [0.38]) (p > 0.05). Those with a longer LoS showed a higher gain in QALY (0.35 [0.42]) than those with a shorter one (0.23 [0.29]) (p < 0.05). The cost per QALY gained was, in median, EUR 14,337, which was lower in males (EUR 13,803), in non-geriatric patients (EUR 13,743), and in patients with a shorter LoS (EUR 10,670) (p > 0.05). Conclusions: Although QALY gains differed among the groups, the median cost per QALY remained consistent. These results highlight the need for targeted interventions to optimize resource allocation, both by integrating data into allocation strategies and by employing a multidisciplinary approach to tailor interventions.

Background: The aim of this study was to assess the cost effectiveness of a screening and treatment intervention approach for chronic HCV infection in Zimbabwe. Methods: Using a decision tree and a validated Markov model, we estimated the lifetime costs and health effects of screening for and treating HCV infections from a healthcare perspective. We evaluated three screening strategies, namely the following: i. no screening; ii. screening among the general population; and iii. screening among high-risk groups. Incremental cost effectiveness ratios were calculated for the strategies that were not dominated. We used deterministic and probabilistic sensitivity analyses to explore the impacts of parameter uncertainty on cost effectiveness outcomes. Results: The strategy of screening among high-risk groups and treating with sofosbuvir/velpatasvir had an incremental cost of USD 1201 and incremental quality-adjusted life years (QALY) of 2.01, yielding an incremental cost effectiveness ratio (ICER) of USD 604 per QALY gained as compared to no screening. The ICER was below the 0.5 times the gross domestic product per capita parameter (USD 796), making the intervention potentially cost effective. The strategy to screen among the general population was dominated, because it costed more and resulted in fewer QALYs than its comparators. Conclusions: Screening for HCV among high-risk populations followed by treatment using sofosbuvir/velpatasvir is cost effective under the assumptions made in this study. Full article

Background: Thrombopoietin receptor agonists—romiplostim, eltrombopag and avatrombopag—are commonly used as second-line treatments for immune thrombocytopenia (ITP). Methods: A Markov model was developed to estimate the cost effectiveness of the three TPO-RAs in adults with insufficient response to previous treatment from the perspective of the UK National Health Service (NHS). The model considered the effects of bleeding events, concomitant ITP medications, rescue therapies and treatment related adverse events over a lifetime horizon. Model inputs for effectiveness were based on a network meta-analysis and other published literature on ITP management. Other model inputs included costs (e.g., drug acquisition and administration) and healthcare resource utilisation. Results: Avatrombopag was associated with higher quality-adjusted life-years (QALYs) (10.979) than romiplostim (10.628) and eltrombopag (10.085), producing incremental QALYs of −0.351 and −0.894, respectively. Avatrombopag was associated with lower total costs (GBP £319,334) compared with romiplostim (GBP 406,361 [cost saving of GBP 87,027]) and higher total costs compared with eltrombopag (GBP 313,987 [incremental cost of GBP 5347]). Avatrombopag therefore dominated romiplostim (more effective and less expensive) and was cost-effective versus eltrombopag (incremental cost-effectiveness ratio of GBP 5982 per QALY). Conclusions: Avatrombopag is a cost-effective treatment compared with romiplostim and eltrombopag for the second-line treatment of adults with ITP from the perspective of the UK NHS. Full article

Background: The prevalence of chronic conditions that increase the risk of influenza complications is high among individuals aged ≥50 years, and evidence suggests age-related changes in immune responses to vaccines begin to decline at this age. Persons aged 50–59 years have high rates of influenza infections and are also the most likely age group to be employed. Thus, the burden of influenza is high in this age group. Methods: We investigated the cost-effectiveness of vaccination with an adjuvanted quadrivalent influenza vaccine (aQIV) in a Spanish population aged ≥50 years at high risk of influenza complications. Using a static decision-tree model specifically designed to analyze Spanish data, we calculated incremental cost-effectiveness ratios (ICERs) for aQIV vs. egg-based QIV (QIVe; indicated for any age) and aQIV vs. high-dose QIV (HD-QIV; indicated for persons aged ≥60 years) from payer and societal perspectives. We compared ICERs against a willingness-to-pay threshold of EUR 25,000 per quality-adjusted life year (QALY) gained. The impact of input uncertainty on ICER was evaluated through a probabilistic sensitivity analysis (PSA) and a one-way deterministic sensitivity analysis (DSA). Results: The total incremental cost of vaccination with aQIV was EUR –86,591,967.67, which was associated with gains of 241.02 in QALY (EUR –359,268.05 per QALY gained) and 318.04 in life years (EUR −272,271.37 per life year gain). Compared with the willingness-to-pay threshold of EUR 25,000 per QALY gained, aQIV was the most cost-effective influenza vaccine relative to the combination of QIVe or HD-QIV. These findings were supported by PSA and DSA analyses. Conclusions: In the model, aQIV dominated QIVe and HD-QIV, demonstrating that aQIV use would be cost-saving for persons aged ≥50 years who are at high risk of influenza complications. Full article

Background/Objectives: This study was conducted to assess the cost-effectiveness of chlorhexidine-coated (AGBA) peripheral insertion central catheters (PICCs) versus standard PICCs for managing catheter-related complications among patients with hematologic disease. Methods: A decision tree health economic model was developed, incorporating quality-adjusted life years (QALYs) derived from the literature, as well as complication rates and per-patient costs from a randomized controlled trial. The base case incremental cost-effectiveness ratio (ICER) was assessed against established willingness to pay (WTP) thresholds. One-way sensitivity analyses were conducted to address assumptions and uncertainties. Results: The mean healthcare cost per patient of standard PICCs was RMB 21,987.32 (USD 3242.82, at an average exchange rate of RMB 678.03 = USD 100), affecting 0.68 QALYs in 90 days. The mean healthcare cost per patient of AGBA PICCs was RMB 19,696.23 (USD 2904.92), affecting 0.73 QALYs in 90 days, thus resulting in a saving of RMB 2291.10 (USD 428.44). After the model simulation, standard PICCs resulted in a reduction of 0.05 QALYs. The ICER for AGBA PICCs compared with standard PICCs was consistently centered at RMB 4271.31 (USD 629.96). Conclusions: one-way sensitivity analyses of cost-effectiveness versus WTP confirmed the robustness of the model across various parameter changes, indicating that AGBA PICCs could provide significant healthcare savings over a 1-year period when adopted in routine chemotherapy treatment for patients with hematologic disease.

Background/Objectives: The omental fat-augmented free flap (O-FAFF) is a novel technique for autologous breast reconstruction in patients who cannot use or who elect not to use more traditional donor sites. While the clinical outcomes of O-FAFF have been well studied, associated costs and resource utilization have not yet been investigated. The O-FAFF technique involves the use of an acellular dermal matrix and a two-team approach for laparoscopic harvest of the omentum, thereby increasing surgical and materials costs. This study compares the longitudinal cost-effectiveness study of O-FAFF breast reconstruction compared to reconstruction using implants or abdominal donor sites (deep inferior epigastric artery flap or transverse rectus abdominis myocutaneous flap). Methods: This cost-effectiveness analysis compared O-FAFF to abdominal free flap and implant-based reconstruction in adults. Markov cohort modeling was used to study cost-effectiveness from the payer perspective. Results: Compared to implant-based reconstruction, the incremental cost of O-FAFF reconstruction was USD 9227 and the incremental gain in breast quality-adjusted life-year (B-QALY) was 0.95, resulting in an incremental cost-effectiveness ratio of USD 9712.64/B-QALY gained, which is well under the acceptable cost-effectiveness threshold of USD 50,000 per B-QALY. Compared to abdominal flap reconstruction, O-FAFF reconstruction was associated with an incremental decrease in direct costs of USD 1410.10 and an incremental gain in B-QALYs of 0.36 and was thus the dominant strategy. Conclusions: The O-FAFF breast reconstruction technique is a cost-effective alternative to more traditional methods of breast reconstruction, including abdominal free flap techniques and implant-based reconstruction. As such, the O-FAFF technique represents an important novel modality for primary autologous reconstruction. Full article

Background/Objectives: Vaccination against SARS-CoV-2 remains a key measure to control COVID-19. Nuvaxovid, a recombinant Matrix-M–adjuvanted protein-based vaccine, showed similar efficacy to mRNA vaccines in clinical trials and real-world studies, with lower rates of reactogenicity. Methods: To support decision making on UK vaccine selection, a population-based compartmental dynamic transmission model with a cost-utility component was developed to evaluate the cost-effectiveness of Nuvaxovid compared with mRNA vaccines from a UK National Health Service perspective. The model was calibrated to official epidemiology statistics for mortality, incidence, and hospitalisation. Scenario and sensitivity analyses were conducted. Results: In the probabilistic base case, a Nuvaxovid-only strategy provided total incremental cost savings of GBP 1,338,323 and 1558 additional quality-adjusted life years (QALYs) compared with an mRNA-only vaccination strategy. Cost savings were driven by reduced cold chain-related operational costs and vaccine wastage, while QALY gains were driven by potential differences in vaccine tolerability. Probabilistic sensitivity analysis indicated an approximately 70% probability of cost-effectiveness with Nuvaxovid-only versus mRNA-only vaccination across most cost-effectiveness thresholds (up to GBP 300,000/QALY gained). Conclusions: Nuvaxovid remained dominant over mRNA vaccines in scenario analyses assessing vaccine efficacy waning, Nuvaxovid market shares, and the vaccinated population. Full article

Objective: This study aimed to measure changes in preferences regarding health-related quality of life associated with COVID-19 and RSV illness in children and adults from 2021 (during the COVID-19 pandemic) to 2023 (post-pandemic). Methods: A stated-preference survey elicited time trade-off (TTO) values from US adults in spring 2021 (n = 1014) and summer 2023 (n = 1186). Respondents were asked to indicate how much time they would hypothetically be willing to trade from the end of their life to avoid the effects of varying severities of COVID-19 and RSV illness for: (1) children; (2) parents of an ill child (family spillover); and (3) adults. Attitudes relating to COVID-19 vaccination and data on experience with COVID-19 or RSV illness were also collected. The primary outcome measure was the loss in quality-adjusted life years (QALYs). Changes in preferences over the time period from 2021 to 2023 were evaluated using regression analysis. Results: QALY losses increased with disease severity and were highest for Long COVID. Across all COVID-19 and RSV health states, QALY losses associated with child health states were higher than family spillover or adult health states. In the regression analysis, QALY losses reported in the 2023 survey were significantly lower than 2021 QALY losses for COVID-19, but not RSV. Conclusions: Preferences may change over time in a pandemic context and therefore, economic analyses of pandemic interventions should consider the timeframe of health preference data collection to determine whether they are suitable to include in an economic evaluation. Even with the impacts on health-related quality of life attenuated over time, childhood illnesses still had a measurable impact on caregivers’ quality of life. Full article

Background/Objectives: Respiratory syncytial virus (RSV) is a leading cause of respiratory infections in children. A novel RSVpreF vaccine for use among pregnant women for the prevention of RSV in infants is expected to be licensed in Mexico. Hence, the clinical and economic burden of RSV among infants in Mexico, with and without a year-round RSVpreF maternal vaccination program, was estimated. Methods: A cohort model was developed to project clinical and economic outcomes of RSV from birth to 1 year of age for maternal vaccination and no intervention. Incremental cost-effectiveness ratios were calculated from direct cost outcomes, life years, and quality-adjusted life years (QALYs). The value per dose of the RSVpreF for which the program would be cost-effective was explored. Analyses were conducted from the healthcare system perspective, with direct costs (2024 Mexican Pesos [MXN]) and outcomes discounted at 5% annually; scenario and sensitivity analyses tested the robustness of model settings and inputs. Results: Compared to no intervention, a year-round RSVpreF vaccine administered to 1891 M pregnant women would prevent 15,768 hospitalizations, 5505 emergency department cases, and 5505 physician office visits annually, averting MXN 1754 M in direct medical costs with an increase of 3402 life years or 3666 QALYs. The RSVpreF vaccine would be cost-saving up to MXN 1301/dose and cost-effective up to MXN 2105–MXN 3715/dose under an assumed cost-effectiveness threshold range of 1–3× the gross domestic product (GDP) per capita (MXN 247,310) per QALY gained. Conclusions: Year-round RSVpreF maternal vaccination would substantially reduce RSV’s clinical and economic burden among infants in Mexico and likely be a cost-effective program. Full article

Background/Objectives: Functional dyspepsia is associated with abdominal pain and nausea, which leads to reduced quality of life, loss of productivity, and economic loss for patients. Itopride hydrochloride (itopride) stimulates the gastrointestinal smooth muscles, thereby promoting gastric emptying. It has been shown to significantly improve symptoms in patients with functional dyspepsia without severe side effects. Itopride has been available in Vietnam for many years; however, the cost-effectiveness of the drug has not been established. The aim of this study is to estimate the cost-effectiveness of itopride for the treatment of functional dyspepsia in Vietnam. Methods: A 3-stage Markov model with the following health states—controlled functional dyspepsia, uncontrolled functional dyspepsia, and dead—was developed. Functional dyspepsia was used to assess itopride over 10 years using 8-week cycles. A broader Vietnamese societal perspective was assumed for the analysis. Input was retrieved from the literature and through local clinical input from physicians in Vietnam. Output was reported as an incremental cost-effectiveness ratio (ICER) per quality-adjusted life years (QALY). A GDP/capita threshold (very cost-effective: 1 × GDP = Vietnamese Dong (VND) 64.1 M, cost-effective: 3 × GDP = VND 192.2 M) was used as recommended by the WHO in Vietnam. One-way and probabilistic sensitivity analyses were performed. Results: Itopride use resulted in an additional 0.28 QALYs at an extra cost of VND 11.2 M. This resulted in an ICER of VND 39.7 M per QALY, which is lower than the threshold of VND 192.2 M. One-way sensitivity analyses showed that the ICER was sensitive to varying the efficacy VND 31.8 M to VND 88.3 M), cost of itopride (ICER: VND 43.1 M to VND 56.5 M), and the health utility values (ICER: VND 45.2 M to VND 55.3 M). More than 80% of the simulations in the probabilistic sensitivity analysis were cost-effective at the 1 × GDP (VND 64.1 M) threshold, and 91.3% were cost-effective at the 3 × GDP (VND 192.2 M) threshold. Conclusion: This study shows that itopride hydrochloride is a very cost-effective treatment for functional dyspepsia in Vietnam, with the ICER (VND 39.7 M/QALY) being even lower than the 1 × GDP (VND 64.1 M) threshold.
