ABSTRACT
BACKGROUND: Patients living with life-limiting illnesses other than cancer constitute the majority of patients in need of palliative care globally, yet most previous systematic reviews of the cost impact of palliative care have not exclusively focused on this population. Reviews that tangentially looked at non-cancer patients found inconclusive evidence. Randomised controlled trials (RCTs) are the gold standard for treatment efficacy, while total health care costs offer a comprehensive measure of resource use. In the sole review of RCTs for non-cancer patients, palliative care reduced hospitalisations and emergency department visits but its effect on total health care costs was not assessed. The aim of this study is to review RCTs to determine the difference in costs between a palliative care approach and usual care in adult non-cancer patients with a life-limiting illness. METHODS: A systematic review using a narrative synthesis approach. The protocol was registered with PROSPERO prospectively (no. CRD42020191082). Eight databases were searched: Medline, CINAHL, EconLit, EMBASE, TRIP database, NHS Evidence, Cochrane Library, and Web of Science from inception to January 2023. Inclusion criteria were: English or German; randomised controlled trials (RCTs); adult non-cancer patients (> 18 years); palliative care provision; a comparator group of standard or usual care. Quality of studies was assessed using Drummond's checklist for assessing economic evaluations. RESULTS: Seven RCTs were included and examined the following diseases: neurological (3), heart failure (2), AIDS (1) and mixed (1). The majority (6/7) were home-based interventions. All studies were either cost-saving (3/7) or cost-neutral (4/7); and four had improved outcomes for patients or carers and three no change in outcomes. CONCLUSIONS: In a non-cancer population, this is the first systematic review of RCTs that has demonstrated a palliative care approach is cost-saving or at least cost-neutral. Cost savings are achieved without worsening outcomes for patients and carers. These findings lend support to calls to increase palliative care provision globally.

BACKGROUND: Orthogeriatric co-management (OGCM) addresses the special needs of geriatric fracture patients. Most of the research on OGCM focused on hip fractures while results concerning other severe fractures are rare. We conducted a health-economic evaluation of OGCM for pelvic and vertebral fractures. METHODS: In this retrospective cohort study, we used German health and long-term care insurance claims data and included cases of geriatric patients aged 80 years or older treated in an OGCM (OGCM group) or a non-OGCM hospital (non-OGCM group) due to pelvic or vertebral fractures in 2014-2018. We analyzed life years gained, fracture-free life years gained, healthcare costs, and cost-effectiveness within 1 year. We applied entropy balancing, weighted gamma and two-part models. We calculated incremental cost-effectiveness ratios and cost-effectiveness acceptability curves. RESULTS: We included 21,036 cases with pelvic (71.2% in the OGCM, 28.8% in the non-OGCM group) and 33,827 with vertebral fractures (72.8% OGCM, 27.2% non-OGCM group). 4.5-5.9% of the pelvic and 31.8-33.8% of the vertebral fracture cases were treated surgically. Total healthcare costs were significantly higher after treatment in OGCM compared to non-OGCM hospitals for both fracture cohorts. For both fracture cohorts, a 95% probability of cost-effectiveness was not exceeded for a willingness-to-pay of up to 150,000 per life year or 150,000 per fracture-free life year gained. CONCLUSION: We did not obtain distinct benefits of treatment in an OGCM hospital. Assigning cases to OGCM or non-OGCM group on hospital level might have underestimated the effect of OGCM as not all patients in the OGCM group have received OGCM.

Cellular agriculture aims to meet the growing demand for animal products. However, current production technologies result in low yields, leading to economic projections that prohibit cultivated meat scalability. Here we use tangential flow filtration for continuous manufacturing of cultivated meat to produce biomass of up to 130 × 106 cells per ml, corresponding to yields of 43% w/v and multiple harvests for over 20 days. Continuous manufacturing was carried out in an animal-component-free culture medium for US$0.63 l-1 that supports the long-term, high density culture of chicken cells. Using this empirical data, we conducted a techno-economic analysis for a theoretical production facility of 50,000 l, showing that the cost of cultivated chicken can drop to within the range of organic chicken at US$6.2 lb-1 by using perfusion technology. Whereas other variables would also affect actual market prices, continuous manufacturing can offer cost reductions for scaling up cultivated meat production.

Nurses are uniquely positioned to significantly impact organizational and system improvement through improving quality and reducing costs. Using an evidenced based tool to identify costs and the financial benefit involved in any quality improvement project is invaluable in developing and evaluating proposals and allocation of resources to support the organization's financial health and viability. The return on investment analysis is an essential accounting tool that will provide nurse leaders with critical information quantifying costs and benefits of both financial and nonfinancial metrics to identify the feasibility, efficacy, risk or efficiency of a proposed project.

BACKGROUND: Behaviour change interventions can result in lasting improvements in physical activity (PA). A broad implementation of behaviour change interventions are likely to be associated with considerable additional costs, and the evidence is unclear whether they represent good value for money. The aim of this study was to investigate costs and cost-effectiveness of behaviour change interventions to increase PA in community-dwelling adults. METHODS: A search for trial-based economic evaluations investigating behaviour change interventions versus usual care or alternative intervention for adults living in the community was conducted (September 2023). Studies that reported intervention costs and incremental cost-effectiveness ratios (ICERs) for PA or quality-adjusted life years (QALYs) were included. Methodological quality was assessed using the Consensus Health Economic Criteria (CHEC-list). A Grading of Recommendations Assessment, Development and Evaluation style approach was used to assess the certainty of evidence (low, moderate or high certainty). RESULTS: Sixteen studies were included using a variety of economic perspectives. The behaviour change interventions were heterogeneous with 62% of interventions being informed by a theoretical framework. The median CHEC-list score was 15 (range 11 to 19). Median intervention cost was US$313 per person (range US$83 to US$1,298). In 75% of studies the interventions were reported as cost-effective for changes in PA (moderate certainty of evidence). For cost per QALY/gained, 45% of the interventions were found to be cost-effective (moderate certainty of evidence). No specific type of behaviour change intervention was found to be more effective. CONCLUSIONS: There is moderate certainty that behaviour change interventions are cost-effective approaches for increasing PA. The heterogeneity in economic perspectives, intervention costs and measurement should be considered when interpreting results. There is a need for increased clarity when reporting the functional components of behaviour change interventions, as well as the costs to implement them.

BACKGROUND: There is increasing interest in the capacity of adaptive designs to improve the efficiency of clinical trials. However, relatively little work has investigated how economic considerations - including the costs of the trial - might inform the design and conduct of adaptive clinical trials. METHODS: We apply a recently published Bayesian model of a value-based sequential clinical trial to data from the 'Hydroxychloroquine Effectiveness in Reducing symptoms of hand Osteoarthritis' (HERO) trial. Using parameters estimated from the trial data, including the cost of running the trial, and using multiple imputation to estimate the accumulating cost-effectiveness signal in the presence of missing data, we assess when the trial would have stopped had the value-based model been used. We used re-sampling methods to compare the design's operating characteristics with those of a conventional fixed length design. RESULTS: In contrast to the findings of the only other published retrospective application of this model, the equivocal nature of the cost-effectiveness signal from the HERO trial means that the design would have stopped the trial close to, or at, its maximum planned sample size, with limited additional value delivered via savings in research expenditure. CONCLUSION: Evidence from the two retrospective applications of this design suggests that, when the cost-effectiveness signal in a clinical trial is unambiguous, the Bayesian value-adaptive design can stop the trial before it reaches its maximum sample size, potentially saving research costs when compared with the alternative fixed sample size design. However, when the cost-effectiveness signal is equivocal, the design is expected to run to, or close to, the maximum sample size and deliver limited savings in research costs.

BACKGROUND: The economic assessment of health care models in palliative care promotes their global development. The purpose of the study is to assess the cost-effectiveness of a palliative care program (named Contigo) with that of conventional care from the perspective of a health benefit plan administrator company, Sanitas, in Colombia. METHODS: The incremental cost-utility ratio (ICUR) and the incremental net monetary benefit (INMB) were estimated using micro-costing in a retrospective, analytical cross-sectional study on the care of terminally ill patients enrolled in a palliative care program. A 6-month time horizon prior to death was used. The EQ-5D-3 L questionnaire (EQ-5D-3 L) and the McGill Quality of Life Questionnaire (MQOL) were used to measure the quality of life. RESULTS: The study included 43 patients managed within the program and 16 patients who received conventional medical management. The program was less expensive than the conventional practice (difference of 1,924.35 US dollars (USD), P = 0.18). When compared to the last 15 days, there is a higher perception of quality of life, which yielded 0.25 in the EQ-5D-3 L (p < 0.01) and 1.55 in the MQOL (P < 0.01). The ICUR was negative and the INMB was positive. CONCLUSION: Because the Contigo program reduces costs while improving quality of life, it is considered to be net cost-saving and a model with value in health care. Greater availability of palliative care programs, such as Contigo, in Colombia can help reduce existing gaps in access to universal palliative care health coverage, resulting in more cost-effective care.

BACKGROUND: Despite ongoing efforts, perinatal morbidity and mortality persist across all settings, imposing a dual burden of clinical and economic strain. Besides, the fragmented nature of economic evidence on perinatal health interventions hinders the formulation of effective health policies. Our review aims to comprehensively and critically assess the economic evidence for such interventions in high-income countries, where the balance of health outcomes and fiscal prudence is paramount. METHODS AND ANALYSIS: We will conduct a comprehensive search for studies using databases including EconLit (EBSCO), Cost Effectiveness Analysis (CEA) Registry, Medline (Ovid), Embase (Ovid), CINAHL Ultimate (EBSCO), Global Health (Ovid), and PubMed. Furthermore, we will broaden our search to include Google Scholar and conduct snowballing from the final articles included. The search terms will encompass economic evaluation, perinatal health interventions, morbidity and mortality, and high-income countries. We will include full economic evaluations focusing on cost-effectiveness, cost-benefit, cost-utility, and cost-minimisation analyses. We will exclude partial economic evaluations, reports, qualitative studies, conference papers, editorials, and systematic reviews. Date restrictions will limit the review to studies published after 2010 and those in English during the study selection process. We will use the modified Drummond checklist to evaluate the quality of each included study. Our findings will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 statement. A summary will include estimated costs, effectiveness, benefits, and the incremental cost-effectiveness ratio (ICER). We also plan to conduct a subgroup analysis. To aid comparability, we will standardise all costs to the United States Dollar, adjusting them to their 2022 value using country-specific consumer price index and purchasing power parity. ETHICS AND DISSEMINATION: This systematic review will not involve human participants and requires no ethical approval. We will publish the results in a peer-reviewed journal. TRIAL REGISTRATION: We registered our record on PROSPERO (registration #: CRD42023432232).

BACKGROUND: Chronic migraine (CM) is the most severe and burdensome subtype of migraine. Fremanezumab is a monoclonal antibody that targets the calcitonin gene-related peptide pathway as a migraine preventive therapy. This study aimed to conduct a cost-effectiveness analysis of fremanezumab from a societal perspective in the Netherlands, using a Markov cohort simulation model. METHODS: The base-case cost-effectiveness analysis adhered to the Netherlands Authority guidelines. Fremanezumab was compared with best supportive care (BSC; acute migraine treatment only) in patients with CM and an inadequate response to topiramate or valproate and onabotulinumtoxinA (Dutch patient group [DPG]). A supportive analysis was conducted in the broader group of CM patients with prior inadequate response to 2-4 different classes of migraine preventive treatments. One-way sensitivity, probabilistic sensitivity, and scenario analyses were conducted. RESULTS: Over a lifetime horizon, fremanezumab is cost saving compared with BSC in the DPG (saving of 2514 per patient) and led to an increase of 1.45 quality-adjusted life-years (QALYs). In the broader supportive analysis, fremanezumab was cost effective compared with BSC, with an incremental cost-effectiveness ratio of 2547/QALY gained. Fremanezumab remained cost effective in all sensitivity and scenario analyses. CONCLUSION: In comparison to BSC, fremanezumab is cost saving in the DPG and cost effective in the broader population.

BACKGROUND: Recent years have seen a growing interest in the use of digital tools for delivering person-centred mental health care. Experience Sampling Methodology (ESM), a structured diary technique for capturing moment-to-moment variation in experience and behaviour in service users' daily life, reflects a particularly promising avenue for implementing a person-centred approach. While there is evidence on the effectiveness of ESM-based monitoring, uptake in routine mental health care remains limited. The overarching aim of this hybrid effectiveness-implementation study is to investigate, in detail, reach, effectiveness, adoption, implementation, and maintenance as well as contextual factors, processes, and costs of implementing ESM-based monitoring, reporting, and feedback into routine mental health care in four European countries (i.e., Belgium, Germany, Scotland, Slovakia). METHODS: In this hybrid effectiveness-implementation study, a parallel-group, assessor-blind, multi-centre cluster randomized controlled trial (cRCT) will be conducted, combined with a process and economic evaluation. In the cRCT, 24 clinical units (as the cluster and unit of randomization) at eight sites in four European countries will be randomly allocated using an unbalanced 2:1 ratio to one of two conditions: (a) the experimental condition, in which participants receive a Digital Mobile Mental Health intervention (DMMH) and other implementation strategies in addition to treatment as usual (TAU) or (b) the control condition, in which service users are provided with TAU. Outcome data in service users and clinicians will be collected at four time points: at baseline (t0), 2-month post-baseline (t1), 6-month post-baseline (t2), and 12-month post-baseline (t3). The primary outcome will be patient-reported service engagement assessed with the service attachment questionnaire at 2-month post-baseline. The process and economic evaluation will provide in-depth insights into in-vivo context-mechanism-outcome configurations and economic costs of the DMMH and other implementation strategies in routine care, respectively. DISCUSSION: If this trial provides evidence on reach, effectiveness, adoption, implementation and maintenance of implementing ESM-based monitoring, reporting, and feedback, it will form the basis for establishing its public health impact and has significant potential to bridge the research-to-practice gap and contribute to swifter ecological translation of digital innovations to real-world delivery in routine mental health care.

OBJECTIVES: Cost-effectiveness analyses are increasingly used to inform subvention decisions for moderately life extending treatments but apply several simplifying assumptions that may be inconsistent with public preferences. Contrary to standard assumptions, we hypothesize that societal willingness to allocate public funding toward these treatments is (1) diminishing for incremental improvements in survival and quality of life (QoL) and (2) greater for subvention policies that exclude the oldest old (>80 years). METHODS: We tested these hypotheses using a web-based discrete choice experiment (n = 425) in Singapore. In each of 5 questions, respondents were shown 2 hypothetical treatments targeting patients with an expected prognosis of 2 months at very poor QoL and asked which treatment they wanted the government to subsidize, if any. Treatments were defined by 4 attributes: cost to the government, age of beneficiaries, expected gain in survival (2-12 months), and QoL (poor, fair, and good). RESULTS: Latent class models were used to analyze results. Results revealed 2 classes. In the majority class (69.7% of sample), respondents value incremental gains in survival and QoL at a diminishing rate. Their willingness to allocate public funding estimates (Singapore dollars 16 825-91 027 per patient per month) were much higher than traditional cost-effectiveness thresholds. In the second class, respondents were unwilling to subsidize treatments offering less than 2 months of life extension or poor QoL. Neither class preferred subvention policies that exclude the oldest old. CONCLUSIONS: These findings suggest that the Singapore government should consider cost-effectiveness thresholds that rise with increases in life extension. Age-based restrictions should not be imposed.

OBJECTIVES: Criteria for antiviral treatment initiation in Thailand were complex and difficult to implement. This study determined the cost-effectiveness of 2 simplified antiviral treatment initiation criteria among patients with chronic hepatitis B in Thailand. METHODS: A hybrid model of the decision tree and Markov model was developed. Two simplified antiviral treatment initiation criteria were the expanded criteria, treating patients with hepatitis B surface antigen positive and viral load (hepatitis B virus deoxyribonucleic acid) >2000 IU/mL or cirrhosis by tenofovir alafenamide (TAF), and the test-and-treat criteria, treating patients with hepatitis B surface antigen positive and viral load >10 IU/mL or cirrhosis by TAF. PubMed was searched from its inception to July 2023 to identify input parameters. Best supportive care was chosen for patients who were ineligible for TAF. Incremental cost-effectiveness ratio per quality-adjusted life-year (QALY) was calculated. RESULTS: The expanded criteria and the test-and-treat could reduce the occurrence of patients progressing to hepatocellular carcinoma. In particular, both criteria could reduce 4846 new cases of hepatocellular carcinoma per 100 000 patients. The incremental cost-effectiveness ratios for the expanded criteria and the test-and-treat criteria were 24 838 Thai baht (THB)/QALY and 163 060 THB/QALY, respectively. CONCLUSIONS: At the current willingness to pay of 160 000 THB/QALY, the expanded criteria were cost-effective, but the test-and-treat criteria were not cost-effective to be the simplified antiviral treatment initiation criteria for patients with chronic hepatitis B in Thailand.

OBJECTIVES: Healthcare research and development have accelerated at an unprecedented rate creating a challenge even for high-income countries to finance all new technologies. Health technology assessment (HTA) aims to maximize health gains out of available resources. Our study aimed to provide tailor-made recommendations for HTA implementation in the United Arab Emirates (UAE). METHODS: We conducted a policy survey to explore the gap between the current and preferred future environment of HTA implementation in the UAE. The survey was distributed in 2 workshops discussing the importance of HTA implementation, and results were further aggregated to yield a list of draft recommendations. Recommendations were then assessed for their feasibility in a round table discussion with experts in the field to generate actions for HTA implementation. RESULTS: Survey results and round table discussion indicated the need to leverage HTA for value-based decision making. Experts confirmed the unmet need for broader coverage of graduate and postgraduate HTA training with the aim of specific PhD programs in the UAE. Public funding for HTA appraisals and expanding the scope of HTA to nonpharmaceuticals was recommended. Furthermore, experts recommended that several HTA bodies should be coordinated centrally and highlighted the importance of having an explicit soft cost-effectiveness threshold for common technologies and a higher threshold for orphan drugs. CONCLUSIONS: Although HTA in the UAE is still in its early stages, strong initiatives are being taken for its implementation. Our survey results served as a step in developing a detailed action plan for HTA implementation that will enhance the sustainability of the healthcare system.

OBJECTIVES: To assess the cost-effectiveness of maintenance pemetrexed plus best supportive care (BSC) in non-small cell lung cancer patients from a Jordanian healthcare system perspective. METHODS: A Markov model with 4 health states was developed to estimate life years, quality-adjusted life-years (QALY), costs, and the incremental cost-utility ratio of pemetrexed plus BSC versus BSC. A lifelong time horizon was used in the base-case analysis. The transition probabilities were estimated from the PARAMOUNT trial, the utility weights were taken from published literature, and costs were based on data and unit costs at King Hussein Cancer Center and the Jordan Food and Drug Administration. Both costs and outcomes were discounted using a 3%. The parameter uncertainty was tested using deterministic and probabilistic sensitivity analyses. RESULTS: The base-case analysis showed that pemetrexed plus BSC increased QALYs and cost compared with BSC. Pemetrexed plus BSC leads to incremental 0.255 QALYs and incremental costs of US $30 826, resulting in an incremental cost-utility ratio of US $120 886/QALY. The results were sensitive to changes in the utility estimates during the progression-free health state, the progression health state, and the cost of postprogression medications The probabilistic sensitivity analysis showed that the probability of pemetrexed plus BSC being a cost-effective option compared with BSC is 0 at a threshold of $56 000. CONCLUSIONS: Maintenance pemetrexed for non-small cell lung cancer is not a cost-effective option compared with BSC from a healthcare system perspective based on the listed price at a threshold of $56 000/QALY.

Nanomaterials excel in mimicking the structure and function of natural enzymes while being far more interesting in terms of structural stability, functional versatility, recyclability, and large-scale preparation. Herein, the story assembles hemin, histidine analogs, and G-quadruplex DNA in a catalytically competent supramolecular assembly referred to as assembly-activated hemin enzyme (AA-heminzyme). The catalytic properties of AA-heminzyme are investigated both in silico (by molecular docking and quantum chemical calculations) and in vitro (notably through a systematic comparison with its natural counterpart horseradish peroxidase, HRP). It is found that this artificial system is not only as efficient as HRP to oxidize various substrates (with a turnover number kcat of 115 s-1) but also more practically convenient (displaying better thermal stability, recoverability, and editability) and more economically viable, with a catalytic cost amounting to <10% of that of HRP. The strategic interest of AA-heminzyme is further demonstrated for both industrial wastewater remediation and biomarker detection (notably glutathione, for which the cost is decreased by 98% as compared to commercial kits).

OBJECTIVES: To estimate the expected value of undertaking a future randomized controlled trial of thresholds used to initiate invasive ventilation compared with usual care in hypoxemic respiratory failure. PERSPECTIVE: Publicly funded healthcare payer. SETTING: Critical care units capable of providing invasive ventilation and unconstrained by resource limitations during usual (nonpandemic) practice. METHODS: We performed a model-based cost-utility estimation with individual-level simulation and value-of-information analysis focused on adults, admitted to critical care, receiving noninvasive oxygen. In the primary scenario, we compared hypothetical threshold A to usual care, where threshold A resulted in increased use of invasive ventilation and improved survival compared with usual care. In the secondary scenario, we compared hypothetical threshold B to usual care, where threshold B resulted in decreased use of invasive ventilation and similar survival compared with usual care. We assumed a willingness-to-pay of 100,000 Canadian dollars (CADs) per quality-adjusted life year. RESULTS: In the primary scenario, threshold A was cost-effective compared with usual care due to improved hospital survival (78.1% vs. 75.1%), despite more use of invasive ventilation (62% vs. 30%) and higher lifetime costs (86,900 vs. 75,500 CAD). In the secondary scenario, threshold B was cost-effective compared with usual care due to similar survival (74.5% vs. 74.6%) with less use of invasive ventilation (20.2% vs. 27.6%) and lower lifetime costs (71,700 vs. 74,700 CAD). Value-of-information analysis showed that the expected value to Canadian society over 10 years of a 400-person randomized trial comparing a threshold for invasive ventilation to usual care in hypoxemic respiratory failure was 1.35 billion CAD or more in both scenarios. CONCLUSIONS: It would be highly valuable to society to identify thresholds that, in comparison to usual care, either increase survival or reduce invasive ventilation without reducing survival.

There has been an increasingly prevalent message that data regarding costs must be included in conservation planning activities to make cost-efficient decisions. Despite the growing acceptance that socioeconomic context is critical to conservation success, the approaches to embedded economic and financial considerations into planning have not significantly evolved. Inappropriate cost data is frequently included in decisions, with the potential of compromising biodiversity and social outcomes. For each conservation planning step, this essay details common mistakes made when considering costs, proposing solutions to enable conservation managers to know when and how to include costs. Appropriate use of high-quality cost data obtained at the right scale will improve decision-making and ultimately avoid costly mistakes.

OBJECTIVES: This study aimed to assess direct costs of percutaneous coronary intervention (PCI) without hospital admission versus PCI with hospital admission longer than 24 hours in a private hospital-institutional perspective in the Dominican Republic in 2022. METHODS: This study has a comparative approach based on a prospective cross-sectional partial-cost analysis. We evaluated the direct costs of 10 patients from PCI without hospital admission approach and 10 patients from a hospital admission longer than 24 hours as a control group. We used a "first-come-first-served" approach from December 2021 to March 2022. The analysis used the electronic invoice generated for each patient. RESULTS: PCI without hospital admission approach represents $472.56 in patient savings, equivalent to a cost reduction of 12.5%. The subcosts analysis showed the pharmacy section as the main driver of the overall cost difference. CONCLUSIONS: PCI without hospital admission was economically cost-saving compared with the control approach in direct costs in the Dominican perspective. The economic benefit is substantial and compliments the ease of use. This analysis may lead to improvements in institutional management of resources and can potentially be adapted to other health systems in the region.

In recent years, newer drugs, such as ibrutinib, have shown promising improvements in the survival of patients with chronic lymphocytic leukemia (CLL). Despite their effectiveness, concerns about their cost have arisen, prompting the need for an evaluation of their cost-effectiveness. However, recent assessments of ibrutinib's cost-effectiveness for treating CLL in India reveal divergent conclusions. The discord centers on divergent cost-effectiveness thresholds, comparator regimens, cost calculations, and outcome valuation approaches. Such discrepancies affect public health decisions and patient care. The recommendation calls for adherence to methodological guidelines by future studies, fostering consistent findings to empower policy makers and clinicians in leveraging economic evidence for informed decision making in CLL treatment strategies.
