BACKGROUND: Patients with obstructive hypertrophic cardiomyopathy (oHCM) have a substantial humanistic, clinical, and economic burden due to the array of symptoms and complications associated with the disease. The objective of this review was to identify key evidence gaps related to oHCM, specifically in Europe, North America, and Japan.
METHODS: A targeted literature review was conducted using PubMed to identify English-language studies published between 2012 and 2022 assessing patients with HCM/oHCM in France, Germany, Italy, Spain, the United Kingdom (UK), the United States (US), Canada, and Japan. Outcomes of interest were epidemiology, natural history, pathophysiology, management, and clinical, economic, and humanistic burden. Identified studies were assessed qualitatively to characterize evidence gaps.
RESULTS: Among 2,262 abstracts and 531 full-text articles screened, 178 articles were included from PubMed searches. An additional 16 unique studies were identified via a supplemental Google Scholar search initially conducted in January 2023 and updated in July 2024. Disease natural history, pathophysiology, and management were well documented globally. Significant evidence gaps were noted for the epidemiology, treatment, and burden of oHCM. Although multiple US studies were identified on the clinical, economic, and humanistic burden of oHCM, and one clinical burden study was found for Japan, there was a lack of evidence for France, Germany, Italy, Spain, the UK, and Canada.
CONCLUSIONS: Major evidentiary gaps exist for the epidemiology, treatment, and burden of oHCM. Future research should address these gaps, with a specific focus on generating real-world evidence for Canada and European countries that will support the evaluation of emerging therapies in these regions.

OBJECTIVE: To review the economic burden assessment of cervical cancer in low- and middle-income countries (LMICs) and use the findings to develop a pragmatic, standardized framework for such assessment.
METHODS: We first systematically reviewed articles indexed in scientific databases reporting the methodology for collecting and calculating costs related to the cervical cancer burden in LMICs. Data on study design, costing approach, cost perspective, costing period, and cost type (direct medical costs [DMC], direct nonmedical costs [DNMC], and indirect costs [IC]) were extracted. Finally, we summarized the reported limitations in the methodology and used the solutions to inform our framework.
RESULTS: Cervical cancer treatment costs across LMICs vary greatly and can be extremely expensive, up to 70,968 International US dollars. Economic and financial assessment methods also vary greatly across countries. Of the 28 reviewed articles, 25 studies reported DMC for cervical cancer treatment by extracting cost information from billing or insurance databases (eight studies), conducting surveys (five), and estimating the costs (12). Only 11 studies-mainly through surveys-reported DNMC and IC. The economic burden assessment framework includes health care/payer and societal perspectives (DMC, DNMC, IC, and human capital loss) across the cervical cancer screening and treatment continuum. To assess health care/payer costs, we recommend combining the predefined treatment standards with actual local treatment practices, multiplied by unit costs. To assess societal costs, we recommend conducting a cost survey in line with a standardized yet adaptable protocol.
CONCLUSIONS: Our standardized, pragmatic framework allows assessment of economic and financial burden of cervical cancer in LMICs despite the different levels of available resources across countries. This framework will facilitate global comparisons and monitoring and may also be applied to other cancers.

OBJECTIVE: To identify the articles in the existing literature that analyse healthcare costs according to the socioeconomic position (pre- or post-injury) for traumatic brain injury survivors. Secondary aims were to describe the types of costs and socioeconomic characteristics and to determine whether socioeconomic characteristics affect the risk of traumatic brain injury or whether the consequences of trauma alter living conditions post-injury.
METHODS: This scoping review followed the methods proposed by Arksey and O\'Malley. The literature search was performed in 5 databases.
RESULTS: Twenty-two articles were included, published between 1988 and 2023. Only 2 articles (9%) followed the guidelines for economic evaluation of healthcare programmes and 2 articles (9%) evaluated socioeconomic position \"completely\" with 3 main individual measures of socioeconomic characteristics (i.e., education, income, and occupation). The relationship between costs and socioeconomic characteristics could vary in 2 ways in traumatic brain injury: socioeconomic disadvantage was mostly associated with higher healthcare costs, and the cost of healthcare reduced the survivors\' living conditions.
CONCLUSIONS: This work highlights the need for a detailed and methodologically sound assessment of the relationship between socioeconomic characteristics and the costs associated with trauma. Modelling the care pathways of traumatic brain injury would make it possible to identify populations at risk of poor recovery or deterioration following a TBI, and to develop specific care pathways. The aim is to build more appropriate, effective, and equitable care programmes.

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.

This Systematic Review assesses the economic impact of Respiratory Syncytial Virus (RSV) in Latin America and the Caribbean (LAC) in relation to healthcare resource utilization and associated costs. We searched online databases from January 2012 to November 2022 to identify eligible publications. We identified 12 publications that reported direct costs, indirect costs, and resources associated with RSV and its complications. The primary direct medical resources reported were medical services, diagnostics tests and procedures, and length of stay (LOS). Direct total costs per patient ranged widely from $563 to $19,076. Direct costs are, on average, 98% higher than indirect costs. Brazil reported a higher total cost per patient than Colombia, El Salvador, México, Panamá, and Puerto Rico, while for indirect costs per patient, El Salvador and Panamá had higher costs than Brazil, Colombia, and Mexico. The mean LOS in the general ward due to RSV was 6.9 days (range 4 to 20 days) and the mean Intensive Care Unit LOS was 9.1 days (range 4 to 16 days). In many countries of the LAC region, RSV represents a considerable economic burden on health systems, but significant evidence gaps were identified in the region. More rigorous health economic studies are essential to better understand this burden and to promote effective healthcare through an informed decision-making process. Vaccination against RSV plays a critical role in mitigating this burden and should be a priority in public health strategies.

BACKGROUND: Dizziness/vertigo is one of the most common symptoms for which people seek healthcare. However, the healthcare expenditure attributable to dizziness/vertigo in South Korea remains poorly understood. We investigated the healthcare costs due to six major disorders causing dizziness/vertigo using claims data.
METHODS: The healthcare costs were evaluated using all the claims data submitted to the Health Insurance Review and Assessment Service from January 1 to December 31, 2022. The six major vestibular disorders included for analysis were benign paroxysmal positional vertigo (BPPV), psychogenic/persistent postural perceptual dizziness (PPPD), vascular vertigo/dizziness (VVD), vestibular migraine (VM), Meniere\'s disease (MD), and vestibular neuritis (VN).
RESULTS: During the 1-year study period, 4.1% of adults aged 20 or older visited hospitals due to dizziness/vertigo in South Korea. Compared to the general population, the patients with dizziness/vertigo were more often elderly, female, and residents of small towns. The total healthcare cost for the six major vestibular disorders was ₩547.8 billion (approximately $406.5 million). BPPV incurred the highest annual healthcare cost (₩183.5 billion, 33.5%), followed by VVD (₩158.8 billion, 29.0%), MD (₩82.2 billion, 15.0%), psychogenic/PPPD (₩60.3 billion, 11.0%), VN (₩32.9 billion, 6.0%), and VM (₩30.1 billion, 5.5%). The mean healthcare cost per hospital visit due to dizziness/vertigo was ₩96,524 (95% confidence interval, ₩96,194-₩96,855), 30% higher than the average (₩73,948) of the overall healthcare cost per hospital visit over the same period.
CONCLUSIONS: Owing to higher healthcare costs for dizziness/vertigo and increased prevalence of dizziness/vertigo in the aged population, healthcare costs due to dizziness/vertigo will increase rapidly in South Korea. Thus, a guideline for cost-effective management of dizziness/vertigo should be established to reduce the healthcare costs due to these common symptoms.

Idiopathic inflammatory myopathies (IIMs) are rare disorders characterized by inflammation of skeletal muscle, which can result in fatty replacement of muscle, muscle atrophy, and subsequent weakness. Therapeutic advancements have improved clinical outcomes but impose an economic impact on healthcare systems. We aimed to summarize the direct and indirect costs associated with IIMs in a systematic review (PROSPERO Registration #CRD42023443143). Electronic databases (MEDLINE, Embase, CINAHL, and Scopus) were systematically searched for full-length articles (excluding case reports) reporting costs specific to patients diagnosed with an IIM, published between database inception and April 19, 2023. Direct cost categories included inpatient, outpatient, medication, home/long-term care, and durable medical equipment such as mobility and respiratory aids. Indirect costs included lost productivity. Eligibility criteria were met by 21 of the 3,193 unique titles identified. Costs are expressed in 2023 United States of America dollars, with adjustments for differences in purchasing power applied to currency conversions. As no study reported on all cost categories, annualized cost of IIM per patient was estimated by calculating the mean cost per category, and then adding the means of the different cost categories. By this method, IIM was estimated to cost $52,210 per patient per year. Proportional contributions by category were lost productivity (0.278), outpatient care (0.214), medications (0.171), inpatient care (0.161), home/long-term care (0.122), and durable medical equipment (0.053). Newer findings with intravenous immunoglobulin considered first line therapy for IIM demonstrated markedly higher annual medication costs per patient, upwards of $33,900 compared to an average of $3,908 ± $1,042 in older studies. Future cost-effectiveness studies require updated cost-of-illness studies reflecting the evolving sub-classification and treatment options for IIM, and should consider the impact of IIM on patients and their families.

BACKGROUND: Governments around the world are considering regulating access to nicotine e-cigarettes to prevent uptake among youth however people that smoke tobacco may use them to assist with smoking cessation. The health and cost implications of regulating e-cigarette use among populations are unknown but have been explored in modelling studies. We reviewed health economic evaluation and simulation modelling studies that assessed long-term consequences and interpret their potential usefulness for decision-makers.
METHODS: A systematic review with a narrative synthesis was undertaken. Six databases were searched for modelling studies evaluating population-level e-cigarette control policies or interventions restricting e-cigarette use versus more liberalized use. Studies were required to report the outcomes of life years, quality-adjusted life years (QALYs) and/or healthcare costs. The quality of the studies was assessed using two quality assessment tools.
RESULTS: In total, 15 studies were included with nine for the United States and one each for the United Kingdom, Italy, Australia, Singapore, Canada, and New Zealand. Three studies included cost-utility analyses. Most studies involved health state transition (or Markov) closed cohort models. Many studies had limitations with their model structures, data input quality and transparency, and insufficient analyses handling model uncertainty. Findings were mixed with 11 studies concluding that policies permitting e-cigarette use lead to net benefits and 4 studies concluding net losses in life-years or QALYs and/or healthcare costs.Five studies had industry conflicts of interest.
CONCLUSIONS: While authors did conclude net benefit than net harm in more of the studies so far conducted, the significant limitations that we identified with many of the studies in this review, make it uncertain whether or not countries can expect net population harms or benefits of restrictive versus unrestrictive e-cigarette policies. The generalizability of the findings is limited for decision-makers. In light of the deep uncertainty around the health and economic outcomes of e-cigarettes, simulation modelling methods and uncertainty analyses should be strengthened.

BACKGROUND: Breast cancer is currently the leading cause of global cancer incidence. Breast cancer has negative consequences for society and economies internationally due to the high burden of disease which includes adverse epidemiological and economic implications. Our aim is to systematically review the estimated economic burden of breast cancer in the United States (US), Canada, Australia, and Western Europe (United Kingdom, France, Germany, Spain, Italy, Norway, Sweden, Denmark, Netherlands, and Switzerland), with an objective of discussing the policy and practice implications of our results.
METHODS: We included English-language published studies with cost as a focal point using a primary data source to inform resource usage of women with breast cancer. We focussed on studies published since 2017, but with reported costs since 2012. A systematic search conducted on 25 January 2023 identified studies relating to the economic burden of breast cancer in the countries of interest. MEDLINE, Embase, and EconLit databases were searched via Ovid. Study quality was assessed based on three aspects: (1) validity of cost findings; (2) completeness of direct cost findings; and (3) completeness of indirect cost findings. We grouped costs based on country, cancer stage (early compared to metastatic), and four resource categories: healthcare/medical, pharmaceutical drugs, diagnosis, and indirect costs. Costs were standardized to the year 2022 in US (US$2022) and International (Int$2022) dollars.
RESULTS: Fifty-three studies were included. Studies in the US (n = 19) and Canada (n = 9) were the majority (53%), followed by Western European countries (42%). Healthcare/medical costs were the focus for the majority (89%), followed by pharmaceutical drugs (25%), then diagnosis (17%) and indirect (17%) costs. Thirty-six (68%) included early-stage cancer costs, 17 (32%) included metastatic cancer costs, with 23% reporting costs across these cancer stages. No identified study explicitly compared costs across countries. Across cost categories, cost ranges tended to be higher in the US than any other country. Metastatic breast cancer was associated with higher costs than earlier-stage cancer. When indirect costs were accounted for, particularly in terms of productivity loss, they tended to be higher than any other estimated direct cost (e.g., diagnosis, drug, and other medical costs).
CONCLUSIONS: There was substantial heterogeneity both within and across countries for the identified studies\' designs and estimated costs. Despite this, current empirical literature suggests that costs associated with early initiation of treatment could be offset against potentially avoiding or reducing the overall economic burden of later-stage and more severe breast cancer. Larger scale, national, economic burden studies are needed, to be updated regularly to ensure there is an ongoing and evolving perspective of the economic burden of conditions such as breast cancer to inform policy and practice.

Alopecia areata (AA) is managed with prolonged medical treatments and cosmetic therapies, whose cost can be burdensome. We sought to identify the costs of AA treatment and consolidate the available data for the practicing dermatologist by performing a PubMed search of articles indexed for MEDLINE. Ten studies including approximately 16,000 patients with AA across a range of Oxford Centre for Evidence-Based Medicine Levels of Evidence were included. Studies showed that despite the limited efficacy of many AA therapies, patients incurred substantial expenses to manage their AA.
