UNASSIGNED: This systematic literature review (SLR) consolidated economic and healthcare resource utilization (HCRU) evidence for positron emission tomography (PET) and single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) to inform future economic evaluations.
UNASSIGNED: An electronic search was conducted in MEDLINE, Embase, and Cochrane databases from 2012-2022. Economic and HCRU studies in adults who underwent PET- or SPECT-MPI for coronary artery disease (CAD) diagnosis were eligible. A qualitative methodological assessment of existing economic evaluations, HCRU, and downstream cardiac outcomes was completed. Exploratory meta-analyses of clinical outcomes were performed.
UNASSIGNED: The search yielded 13,439 results, with 71 records included. Economic evaluations and comparative clinical trials were limited in number and outcome types (HCRU, downstream cardiac outcomes, and diagnostic performance) assessed. No studies included all outcome types and only one economic evaluation linked diagnostic performance to HCRU. The meta-analyses of comparative studies demonstrated significantly higher rates of early- and late-invasive coronary angiography and revascularization for PET- compared to SPECT-MPI; however, the rate of repeat testing was lower with PET-MPI. The rate of acute myocardial infarction was lower, albeit non-significant with PET- vs. SPECT-MPI.
UNASSIGNED: This SLR identified economic and HCRU evaluations following PET- and SPECT-MPI for CAD diagnosis and determined that existing studies do not capture all pertinent outcome parameters or link diagnostic performance to downstream HCRU and cardiac outcomes, thus, resulting in simplified assessments of CAD burden. A limitation of this work relates to heterogeneity in study designs, patient populations, and follow-up times of existing studies. Resultingly, it was challenging to pool data in meta-analyses. Overall, this work provides a foundation for the development of comprehensive economic models for PET- and SPECT-MPI in CAD diagnosis, which should link diagnostic outcomes to HCRU and downstream cardiac events to capture the full CAD scope.

UNASSIGNED: to provide insights into the recent Ebola virus disease (EVD) outbreaks on different aspects of daily life in the Democratic Republic of the Congo and propose possible solutions.
UNASSIGNED: We collected information regarding the effects of EVD outbreaks on existing systems in the eastern part of the Democratic Republic of the Congo (DRC). We searched the PubMed database using the terms \"impact effect Ebola outbreak system\", \"Management Ebola Poor Resources Settings\", \"Health Economic Challenges Ebola\" and \"Economic impact Ebola systems.\" Only studies focusing on epidemiology, diagnostics, sequencing, vaccination, therapeutics, ecology, work force, governance, healthcare provision and health system, and social, political, and economic aspects were considered. The search included the electronic archives of EVD outbreak reports from government and partners.
UNASSIGNED: EVD outbreaks negatively impacts the functions of countries. The disruption in activities is proportional to the magnitude of the epidemic and slows down the transport of goods, decreases the region\'s tourist appeal, and increases \'brain drain\'. Most low- and medium-income countries, such as the DRC, do not have a long-term holistic emergency plan for unexpected situations or sufficient resources to adequately implement countermeasures against EVD outbreaks. Although the DRC has acquired sufficient expertise in diagnostics, genomic sequencing, administration of vaccines and therapeutics, clinical trials, and research activities, deployment, operation, and maintenance of these expertise and associated tools remains a concern.
UNASSIGNED: Despite the data search extension, additional reports addressing issues related to social aspects of EVD outbreaks in DRC were not retrieved.
UNASSIGNED: National leadership has not yet taken the lead in strategic, operational, or financial aspects. Therefore, national leaders should double their efforts and awareness to encourage local fundraising, sufficient budget al.location, infrastructure construction, equipment provision, and staff training, to effectively support a holistic approach in response to outbreaks, providing effective results, and all types of research activities.

UNASSIGNED: To identify and synthesize evidence regarding how coronavirus disease 2019 (COVID-19) interventions, including vaccines and outpatient treatments, have impacted healthcare resource use (HCRU) and costs in the United States (US) during the Omicron era.
UNASSIGNED: A systematic literature review (SLR) was performed to identify articles published between 1 January 2021 and 10 March 2023 that assessed the impact of vaccination and outpatient treatment on costs and HCRU outcomes associated with COVID-19. Screening was performed by two independent researchers using predefined inclusion/exclusion criteria.
UNASSIGNED: Fifty-eight unique studies were included in the SLR, of which all reported HCRU outcomes, and one reported costs. Overall, there was a significant reduction in the risk of COVID-19-related hospitalization for patients who received an original monovalent primary series vaccine plus booster dose vs. no vaccination. Moreover, receipt of a booster vaccine was associated with a lower risk of hospitalization vs. primary series vaccination. Evidence also indicated a significantly reduced risk of hospitalizations among recipients of nirmatrelvir/ritonavir (NMV/r), remdesivir, sotrovimab, and molnupiravir compared to non-recipients. Treated and/or vaccinated patients also experienced reductions in intensive care unit (ICU) admissions, length of stay, and emergency department (ED)/urgent care clinic encounters.
UNASSIGNED: The identified studies may not represent unique patient populations as many utilized the same regional/national data sources. Synthesis of the evidence was also limited by differences in populations, outcome definitions, and varying duration of follow-up across studies. Additionally, significant gaps, including HCRU associated with long COVID and various high-risk populations and cost data, were observed.
UNASSIGNED: Despite evidence gaps, findings from the SLR highlight the significant positive impact that vaccination and outpatient treatment have had on HCRU in the US, including periods of Omicron predominance. Continued research is needed to inform clinical and policy decision-making in the US as COVID-19 continues to evolve as an endemic disease.

UNASSIGNED: Schizophrenia has the highest median societal cost per patient of all mental disorders. This review summarizes the different costs/cost drivers (cost components) associated with schizophrenia in 10 countries, including all cost types and stakeholder perspectives, and highlights aspects of disease associated with greatest costs.
UNASSIGNED: Targeted literature review based on a search of published research from 2006 to 2021 in the United States (US), United Kingdom (UK), France, Germany, Italy, Spain, Canada, Japan, Brazil, and China.
UNASSIGNED: Sixty-four published articles (primary studies and literature reviews) were included. Comprehensive data were available on costs in schizophrenia overall, with very limited data for individual countries except the US. Most data is related to direct and not indirect costs, with extremely scarce data for several key cost components (adverse events, suicide, long-term care). Total schizophrenia-related per person per year (PPPY) costs were $2,004-94,229, with considerable variability among countries. Indirect costs were the main cost driver (50-90% of all costs), ranging from $1,852 to $62,431 PPPY. However, indirect costs are not collected systematically or incorporated in health technology assessments. Total schizophrenia-related PPPY direct costs were $4,394-31,798, with inpatient cost as the main cost driver (∼20-99% of direct costs). Intangible costs were not reported. Despite limited evidence, total schizophrenia-related costs were higher in patients with than without negative symptoms, largely due to increased costs of medication and medical visits.
UNASSIGNED: As this was not a systematic review, prioritization of studies may have resulted in exclusion of potentially relevant data. All costs were converted to USD but not corrected for inflation or subjected to a gross domestic product deflator.
UNASSIGNED: Direct costs are most commonly reported in schizophrenia. The substantial underreporting of indirect and intangible costs undervalues the true economic burden of schizophrenia from a payer, patient, and societal perspective.
The true costs of diseases such as schizophrenia extend far beyond the obvious direct costs of hospital visits, outpatient appointments and medications to include indirect costs such as loss of productivity among patients and caregivers due to unemployment, early retirement and premature death. This review of literature published between 2006 and 2021 reveals that the indirect costs of schizophrenia actually account for between 50% and 90% of all costs, but are often not taken into account in healthcare planning. In addition, intangible costs, including the pain, suffering, stress, and anxiety experienced by patients and caregivers due to schizophrenia have not been reported in the literature. Costs were also higher for patients with negative symptoms of schizophrenia (where patients appear withdrawn and lacking in emotion, with few social relationships) compared with those with positive symptoms (including delusions or hallucinations). This is largely due to the greater costs for medications and medical visits among patients with negative symptoms. In summary, this review demonstrates that the true cost of schizophrenia, including direct, indirect, and intangible costs, is likely to be substantially higher than the values for the cost of disease currently reported.

UNASSIGNED: Targeted germline testing is recommended for those with or at risk of breast, ovarian, or colorectal cancer. The affordability of genetic sequencing has improved over the past decade, therefore the cost-effectiveness of testing for these cancers is worthy of reassessment.
UNASSIGNED: To systematically review economic evaluations on cost-effectiveness of germline testing in breast, ovarian, or colorectal cancer.
UNASSIGNED: A search of PubMed and Embase databases for cost-effectiveness studies on germline testing in breast, ovarian, or colorectal cancer, published between 1999 and May 2022. Synthesis of methodology, cost-effectiveness, and reporting (CHEERS checklist) was performed.
UNASSIGNED: The incremental cost-effectiveness ratios (ICERs; in 2021-adjusted US$) for germline testing versus the standard care option in hereditary breast or ovarian cancer (HBOC) across target settings were as follows: (1) population-wide testing: 344-2.5 million/QALY; (2) women with high-risk: dominant = 78,118/QALY, 8,337-59,708/LYG; (3) existing breast or ovarian cancer: 3,012-72,566/QALY, 39,835/LYG; and (4) metastatic breast cancer: 158,630/QALY. Likewise, ICERs of germline testing for colorectal cancer across settings were: (1) population-wide testing: 132,200/QALY, 1.1 million/LYG; (2) people with high-risk: 32,322-76,750/QALY, dominant = 353/LYG; and (3) patients with existing colorectal cancer: dominant = 54,122/QALY, 98,790-6.3 million/LYG. Key areas of underreporting were the inclusion of a health economic analysis plan (100% of HBOC and colorectal studies), engagement of patients and stakeholders (95.4% of HBOC, 100% of colorectal studies) and measurement of outcomes (18.2% HBOC, 38.9% of colorectal studies).
UNASSIGNED: Germline testing for HBOC was likely to be cost-effective across most settings, except when used as a co-dependent technology with the PARP inhibitor, olaparib in metastatic breast cancer. In colorectal cancer studies, testing was cost-effective in those with high-risk, but inconclusive in other settings. Cost-effectiveness was sensitive to the prevalence of tested variants, cost of testing, uptake, and benefits of prophylactic measures. Policy advice on germline testing should emphasize the importance of these factors in their recommendations.
Breast, ovarian, prostate, and colorectal cancers are among the top causes of cancer related deaths. A substantial proportion of people with these cancers have inherited mutations. The identification of these gene abnormalities could provide people with opportunities to utilize preventive risk reduction surgeries or undertake frequent routine testing for these cancers. However, genetic testing requires healthcare resources and money. Previous reviews on the cost-effectiveness of genetic testing in familial cancers have concluded that targeted screening i.e., selective assessment of people at high-risk could justify the costs of testing. Our evaluation of economic studies in breast and ovarian cancer, however, suggests that genetic testing is cost-effective across a wide variety of situations starting from the screening of all healthy women above 30 years to the testing of women with existing breast or ovarian cancer. Testing in metastatic breast cancer to inform treatment with Olaparib, a drug known to selectively improve survival in people with genetic mutations, was the sole exception where testing was not cost-effective. Contrary to findings for breast or ovarian cancer, testing for colorectal cancer was cost-effective in people with high-risk i.e., family history but inconclusive in other situations. Evidence on the cost-effectiveness of testing in prostate cancer is lacking and as a result we were not able to provide advice in this cancer group.

UNASSIGNED: Various methods exist for the induction of labor (IOL), and there is limited consensus as to optimal methods. Off-label misoprostol is recommended by the World Health Organization (WHO) for IOL but preparing it into doses suitable for IOL lacks precision, with potential adverse outcomes if dosing is inaccurate. This study explores potential outcomes and costs associated with increased uptake of a low-dose (25 µg) oral misoprostol formulation (Angusta; Norgine BV, Amsterdam) approved for IOL, in France, Belgium, and the Netherlands.
UNASSIGNED: A literature review was undertaken to derive probabilities of delivery outcomes (vaginal, instrumental, and cesarean sections) for IOL methods, from published meta-analyses. Outcomes for oral misoprostol tablets (25 µg) were unavailable in the meta-analyses, so were estimated using data from two published retrospective cohort studies. A model was developed to predict the frequency of IOL outcomes and associated costs at the national level, across multiple scenarios. Scenarios were tested using a moderate, medium, and high increase in oral misoprostol tablet (25 µg) uptake. Market shares, costs, and induction rates were defined for each country using multiple data sources.
UNASSIGNED: Increased uptake of oral misoprostol tablets (25 µg) was estimated to be associated with a slightly increased rate of routine vaginal deliveries, and concurrent decreases in instrumental vaginal deliveries and cesarean sections. Since routine vaginal deliveries are less costly than other delivery outcomes, increased uptake of oral misoprostol tablets (25 µg) within the IOL market has the potential to be cost-saving. These trends were predicted using 25 µg oral misoprostol tablet outcomes informed by both retrospective studies.
UNASSIGNED: Preliminary outcomes suggest that oral misoprostol tablets at 25 µg per dose may improve outcomes in IOL and be cost-saving. Further study is required to validate these findings and assess the comparative efficacy of IOL methods, including oral misoprostol tablets (25 µg).

UNASSIGNED: To estimate the migraine-related healthcare resource utilization (HRU) and costs among patients with improved vs. worsened/stable migraine.
UNASSIGNED: This was a follow-up to a retrospective, panel-based chart review conducted in France, Germany, Italy, and Spain among a panel of physicians (neurologists, headache specialists, and pain specialists) who agreed to participate in patient studies and had treated ≥10 migraine patients in 2017. Eligible physicians extracted data for up to five adults with ≥4 monthly migraine days (MMDs) who initiated a preventive treatment on or after 1 January 2013 and received physician care for ≥6 months after the date of the most recent preventive treatment initiation (index date). Based on the trajectory of migraine severity from the 1-month pre-index period to the 6-month post-index period, cohorts were classified as improved (converting from chronic to episodic or from chronic/episodic to <4 MMDs) or stable/worsened (remaining chronic/episodic or transforming from episodic to chronic) migraine. Migraine-related HRU and costs (2017 €) during the 6-month post-index period were compared between patients with improved vs. stable/worsened migraine.
UNASSIGNED: Overall, 470 patient charts were analyzed, with 339 classified as improved migraine and 131 classified as stable/worsened migraine. After adjusting for within-physician correlation, country, sex, and presence of comorbidities before the index date, the improved migraine cohort had significantly fewer migraine-related physician office visits (-0.81; p < .001), emergency room/accident & emergency (ER/A&E) visits (-0.67; p < .001), and hospitalizations (-0.12; p < .001) in the 6-month post-index period vs. the stable/worsened migraine cohort. Consistent with HRU patterns, the adjusted migraine-related costs for physician office visits (-€42.23; p < .05), hospitalizations (-€215.56; p < .05), and total costs (-€396.81; p < .01) in the 6-month post-index period were significantly reduced for the improved migraine cohort vs. the stable/worsened migraine cohort.
UNASSIGNED: Over a 6-month period following initiation of preventive migraine treatment, patients with improved migraine had significantly lower migraine-related HRU and costs than those with stable/worsened migraine.

UNASSIGNED: Long-acting (LA) recombinant FVIII (rFVIII) products with extended dosing intervals have been developed for the treatment of hemophilia A; however, no direct head-to-head trial has been conducted to compare the efficacy of these products.
UNASSIGNED: A systematic literature search was conducted to identify published Phase III clinical trials of prophylactic LA rFVIII treatment in previously treated patients aged ≥12 years, with moderate-to-severe hemophilia A (endogenous FVIII levels ≤2%). Studies that did not meet these criteria, or did not report the included outcomes, were excluded. Bleeding rates and consumption were extracted and summarized; only data for the dosing frequencies indicated in the US product labels (which are similar to those indicated in the European Medicines Agency labels) were included.
UNASSIGNED: Five articles met the inclusion criteria; these studies only included patients with severe hemophilia A. Treatment length, reported outcomes and dose (range: 20-65 IU/kg) varied between studies. Median annualized bleeding rate (ABR) (IQR) reported in the relevant studies was 1.14 (0.00-4.30), rVIII-SingleChain 2 or 3 times weekly; 1.6 (0.0-4.7), rFVIIIFc 2 times weekly followed by every 3-5 days; 1.9 (0.0-5.8), BAX855 2 times weekly; 1.18 (0.00-4.25), N8-GP every 4 days; 1.9 (0.0-5.2) and 4.1 (2.0-10.6), BAY 94-9027 2 times weekly for the cohort who experienced >1 or <1 bleed in the study run-in phase, respectively. Median spontaneous ABR was 0.0 across studies reporting relevant data. Reported consumption was comparable among all LA products.
UNASSIGNED: The primary limitation of this systematic review was the variation in study design and not all studies reported all desired outcomes, which limited the quantity of data available.
UNASSIGNED: This systematic review identified pivotal trial data for LA rFVIII products. Real-world evidence is needed to understand how these products perform in clinical practice.

Aims: The overall cost and health-related quality of life (HRQoL) associated with current treatments for chronic kidney disease (CKD)-related anemia are not well characterized. A systematic literature review (SLR) was conducted on the costs and HRQoL associated with current treatments for CKD-related anemia among dialysis-dependent (DD) patients. Materials and methods: The authors searched the Cochrane Library, MEDLINE, EMBASE, NHS EED, and NHS HTA for English-language publications. Original studies published between January 1, 2000 and March 17, 2017 meeting the following criteria were included: adult population; study focus was CKD-related anemia; included results on patients receiving iron supplementation, red blood cell transfusion, or erythropoiesis stimulating agents (ESAs); reported results on HRQoL and/or costs. Studies which included patients with DD-CKD, did not directly compare different treatments, and had designs relevant to the objective were retained. HRQoL and cost outcomes, including healthcare resource utilization (HRU), were extracted and summarized in a narrative synthesis. Results: A total of 1,625 publications were retrieved, 15 of which met all inclusion criteria. All identified studies included ESAs as a treatment of interest. Two randomized controlled trials reported that ESA treatment improves HRQoL relative to placebo. Across eight studies comparing HRQoL of patients achieving high vs low hemoglobin (Hb) targets, aiming for higher Hb targets with ESAs generally led to modest HRQoL improvements. Two studies reported that ESA-treated patients had lower costs and HRU compared to untreated patients. One study found that aiming for higher vs lower Hb targets led to reduced HRU, while two other reported that this led to a reduction in cost-effectiveness. Limitations: Heterogeneity of study designs and outcomes; a meta-analysis could not be performed. Conclusions: ESA-treated patients undergoing dialysis incurred lower costs, lower HRU, and had better HRQoL relative to ESA-untreated patients. However, treatment to higher Hb targets led to modest HRQoL improvements compared to lower Hb targets.

Aims: Non-adherence is associated with poor clinical outcomes among patients with asthma. While cost-effectiveness analysis (CEA) is increasingly used to inform value assessment of the interventions, most do not take into account adherence in the analyses. This study aims to: (1) Understand the extent of studies considering adherence as part of the economic analyses, and (2) summarize the methods of incorporating adherence in the economic models. Materials and methods: A literature search was performed from the inception to February 2018 using four databases: PubMed, EMBASE, NHS EED, and the Tufts CEA registry. Decision model-based CEA of asthma were identified. Outcomes of interest were the number of studies incorporating adherence in the economic models, and the incorporating methods. All data were extracted using a standardized data collection form. Results: From 1,587 articles, 23 studies were decision model-based CEA of asthma, of which four CEA (17.4%) incorporated adherence in the analyses. Only the method of incorporating adherence by adjusting treatment effectiveness according to adherence levels was demonstrated in this review. Two approaches were used to derive the associations between adherence and effectiveness. The first approach was to apply a mathematical formula, developed by an expert panel, and the second was to extrapolate the associations from previous published studies. The adherence-adjusted effectiveness was then incorporated in the economic models. Conclusions: A very low number of CEA of asthma incorporated adherence in the analyses. All the CEA adjusted treatment effectiveness according to adherence levels, applied to the economic models.
