UNASSIGNED: To quantify the economic burden associated with tobacco smoking among smokers aged 30-69 years, and second-hand smokers (SHS) aged 15-69 years in Jordan.
UNASSIGNED: A prevalence-based analysis was conducted in alignment with the Economics of Tobacco Toolkit developed by the WHO. The time-horizon of the analysis was one year (2019). Direct and indirect costs were estimated using data from the 2019 Global Burden of Diseases study. The analysis targeted the Jordanian population of smokers aged 30-69 years, and SHS aged 15-69 years. Adjustments were applied for age, gender, and smoking-related diseases. Direct costs were estimated using the smoking-attributable fraction (SAF) and national health expenditures. Indirect costs were divided into morbidity and mortality components. A discount rate of 3.0% and an annual productivity growth rate of 1.0% were assumed in modelling future economic losses. A sensitivity analysis was conducted on the lower and upper estimates of data used in this study.
UNASSIGNED: The cost of tobacco smoking and SHS exposure was estimated at US$2,108 million (95% confidence interval [CI] = US$2,003 million-US$2,245 million). This represents 4.7% (95%CI = 4.5%-5.0%) of national gross domestic product (GDP). Direct costs accounted for 3.1% of national GDP. Tobacco smoking accounted for 85.0% of total cost and SHS exposure accounted for 15.0% of total cost. Direct costs accounted for 67.0% of total cost, while indirect morbidity and mortality costs accounted for 9.0% and 24.0% of total cost, respectively. Non-communicable diseases accounted for 96.0% of total direct costs compared to communicable diseases (4.0% of total direct costs).
UNASSIGNED: Smoking cessation interventions such as raising taxes on cigarettes, protecting people from tobacco smoke, warning labels, plain packaging, and bans on advertising, are crucial for controlling national expenditures for treating smoking-related diseases and for averting future economic losses.
In this work, we aimed to calculate the annual economic impact of tobacco smoking in Jordan in 2019. We used the World Health Organization toolkit methodology to estimate both the direct and indirect costs associated with smoking nationally. Our focus was on Jordanian smokers aged 30-69 years and people exposed to second-hand smoke aged 15–69 years. Direct costs were calculated using epidemiological data on the proportion of health expenditures attributable to smoking and the national health expenditures. Indirect costs were divided into two components: morbidity and mortality. We also projected future economic losses, assuming a 3.0% discount rate and a 1.0% annual growth rate of productivity. Our study estimated that the cost of smoking and exposure to second-hand smoke was US$2,108 million (US$2,003 million-US$2,245 million), which accounted for 4.7% (4.5%-5.0) of Jordan’s gross domestic product. The majority of the cost (85.0%) was due to direct smoking, while 15.0% was due to exposure to second-hand smoke. Direct costs made up 67.0% of the total cost, while the costs related to morbidity and mortality accounted for 9.0% and 24.0% of the total cost, respectively. In conclusion, our study emphasized that tobacco smoking has a significant economic impact on Jordan. Therefore, it is crucial to implement effective smoking cessation programs, such as enforcing existing anti-tobacco policies and raising taxes. These measures can help control national expenditures for treating smoking-related diseases and prevent future economic losses.

UNASSIGNED: Human papillomavirus (HPV) causes several cancers such as cervical cancer and some head and neck (oral cavity, pharynx, and larynx), vulval, vaginal, anal, and penile cancers. As HPV vaccination is available, there is potential to prevent these cancers attributed to HPV and consequently the burden associated with them. The aim of this analysis was to estimate the number of HPV-related cancer deaths and the productivity costs due to years of life lost (YLL) in the United Kingdom (UK).
UNASSIGNED: A model was developed utilizing UK 2019 mortality data sourced from country-specific databases for England, Scotland, Wales, and Northern Ireland for the following HPV-related cancers: head and neck (ICD-10 C00-14 and C32), cervix uteri (C53), vaginal (C51), vulval (C52), anal (C21), and penile (C60). The proportion of deaths and years of life lost (YLL) due to HPV were estimated using HPV attributable fractions for each anatomic location from the published literature. Labor force participation, retirement ages, and mean annual earnings, discounted at 3.5% annually, were applied to YLL to calculate the present value of future lost productivity (PVFLP).
UNASSIGNED: A total of 1817 deaths due to HPV-related cancers were reported in the UK in 2019 resulting in 31,804 YLL. Restricting to only YLL that occurred prior to retirement age yielded a total YPLL of 11,765 and a total PVFLP of £187,764,978.
UNASSIGNED: There is a high disease burden in the UK for HPV-related cancers, with a large economic impact on the wider economy due to productivity losses. Implementing and reinforcing public health measures to maintain high HPV vaccination coverage in both males and females may further facilitate reduction of this burden.

UNASSIGNED: To compare the cost, healthcare utilization, and outcomes between skin and serum-specific IgE (sIgE) allergy testing.
UNASSIGNED: This retrospective cohort study used IBM® MarketScan claims data, from which commercially insured individuals who initiated allergy testing between January 1 and December 31, 2018 with at least 12 months of enrollment data before and after index testing date were included. Cost of allergy testing per patient was estimated by testing pattern: skin only, sIgE only, or both. Multivariable linear regression was used to compare healthcare utilization and outcomes, including office visits, allergy and asthma-related prescriptions, and emergency department (ED) and urgent care (UC) visits between skin and sIgE testing at 1-year post testing (α = 0.05).
UNASSIGNED: The cohort included 168,862 patients, with a mean (SD) age of 30.8 (19.5) years; 100,666 (59.7%) were female. Over half of patients (56.4%, n = 95,179) had skin only testing, followed by 57,291 patients with sIgE only testing and 16,212 patients with both testing. The average cost of allergy testing per person in the first year was $430 (95% CI $426-433) in patients with skin only testing, $187 (95% CI $183-190) in patients with sIgE only testing, and $532 (95% CI $522-542) in patients with both testing. At 1-year follow-up post testing, there were slight increases in allergy and asthma-related prescriptions, and notable decreases in ED visits by 17.0-17.4% and in UC visits by 10.9-12.6% for all groups (all p < 0.01). Patients with sIgE-only testing had 3.2 fewer allergist/immunologist visits than patients with skin-only testing at 1-year follow-up (p < 0.001). Their healthcare utilization and outcomes were otherwise comparable.
UNASSIGNED: Allergy testing, regardless of the testing method used, is associated with decreases in ED and UC visits at 1-year follow-up. sIgE allergy testing is associated with lower testing cost and fewer allergist/immunologist visits, compared to skin testing.

UNASSIGNED: Asthma presents a global health challenge. The main pharmacotherapy is synthetic chemicals and biological-based drugs that are costly, and have significant side effects. In contrast, use of natural products, such as onion (Allium cepa L., Amaryllidaceae) in the treatment of airway diseases has increased world-wide because of their perceived efficacy and little safety concerns. However, their pharmacological actions remain largely uncharacterized.
UNASSIGNED: We investigated whether onion bulb extract (OBE) can (1) reverse established asthma phenotype (therapeutic treatment) and/or (2) prevent the development of the asthma phenotype, if given before the immunization process (preventative treatment).
UNASSIGNED: Six groups of male Balb/c mice were established for the therapeutic (21 days) and five groups for the preventative (19 days) treatment protocols; including PBS and house dust mite (HDM)-challenged mice treated with vehicle or OBE (30, 60, and 100 mg/kg/i.p.). Airways inflammation was determined using cytology, histology, immunofluorescence, Western blot, and serum IgE.
UNASSIGNED: Therapeutic (60 mg/kg/i.p.) and preventative (100 mg/kg/i.p.) OBE treatment resulted in down-regulation of HDM-induced airway cellular influx, histopathological changes and the increase in expression of pro-inflammatory signaling pathway EGFR, ERK1/2, AKT, pro-inflammatory cytokines and serum IgE.
UNASSIGNED: Our data show that OBE is an effective anti-inflammatory agent with both therapeutic and preventative anti-asthma effects. These findings imply that onion/OBE may be used as an adjunct therapeutic agent in established asthma and/or to prevent development of allergic asthma. However, further studies to identify the active constituents, and demonstrate proof-of-concept in humans are needed.

UNASSIGNED: Implantable cardioverter defibrillator (ICDs) for primary prevention (PP) of sudden cardiac arrest (SCA) is underutilized in developing countries. The Improve SCA study has identified a subset of 1.5 primary prevention (1.5PP) patients with a higher risk of SCA and a significant mortality benefit from ICD therapy. From the perspective of China\'s healthcare system, we evaluated the cost-effectiveness of ICD therapy vs. no ICD therapy among 1.5PP patients with a view to informing clinical and policy decisions.
UNASSIGNED: A published Markov model was adjusted and verified to simulate the course of the disease and describe different health states of 1.5PP patients. The patient characteristics, mortality, utility and complication estimates were obtained from the Improve SCA study and other literature. Cost inputs were sourced from government tender prices, medical service prices and clinical experts\' surveys in 9 Chinese public hospitals. For both ICD and no ICD therapy, the total medical costs and quality-adjusted life-years (QALYs) were modelled over a lifetime horizon and the incremental cost-effectiveness ratio (ICER) was calculated. Deterministic and probabilistic sensitivity analyses were performed to assess the uncertainty of the model parameters. We used the willingness-to-pay (WTP) threshold recommended by China Guidelines for Pharmacoeconomic Evaluations, one to three times China\'s GDP per capita (CNY85,698-CNY257,094) in 2022 Chinese Yuan.
UNASSIGNED: The incremental cost effectiveness ratio (ICER) of ICD therapy compared to no ICD therapy is 139,652 CNY/QALY, which is about 1-2 times China\'s GDP per capita. The probability that ICD therapy is cost effective was 92.1%. Results from sensitivity analysis supported the findings of the base case.
UNASSIGNED: ICD therapy compared to no ICD therapy is cost-effective for the 1.5PP patients in China.

UNASSIGNED: Patients with early-stage hormone receptor positive, human epidermal growth factor receptor-2 (HER2) negative invasive breast cancer with 1-3 positive lymph nodes (N1) often undergo surgical excisions followed by adjuvant chemotherapy (ACT). Many patients have no benefit from ACT and receive unnecessary, costly treatment often associated with short- and long-term adverse events (AEs). Gene expression profiling (GEP) assays, such as the 21-gene assay (i.e. the Oncotype DX assay), can identify patients at higher risk for recurrence who may benefit from ACT. However, the budgetary consequence of using the Oncotype DX assay versus no GEP testing in the Netherlands is unknown. Our study therefore assessed it using a cost-consequence model.
UNASSIGNED: A validated model was used to create the N1 model. The model compared the costs and consequences of using the Oncotype DX assay versus no GEP testing and MammaPrint, and subsequent ACT use with corresponding costs for chemotherapy, treatment of AEs, productivity losses, GEP testing, and treatment of recurrences, according to the Oncotype DX results. The model time horizon was 5 years.
UNASSIGNED: Costs for the total population amounted to €8.0 million (M), €16.2 M, and €9.5 M, and cost per patient amounted to €13,540, €27,455, and €16,154 for using the Oncotype DX assay, no GEP testing, and MammaPrint, respectively. Total cost savings of using the Oncotype DX assay amounted to €8.2 M versus no GEP testing and €1.5 M versus MammaPrint. Using the Oncotype DX assay would result in fewer patients receiving ACT and thus fewer AEs, sick days, and hospitalizations, leading to overall cost savings compared with no GEP testing and MammaPrint.
UNASSIGNED: Implementing Oncotype DX testing in this population can prevent unnecessary overtreatment, reducing clinical and economic burden on the patient and Dutch healthcare system.
Early-stage invasive breast cancer patients often undergo surgery followed by adjuvant chemotherapy. However, many of these patients have no benefit from adjuvant chemotherapy and thus receive unnecessary and costly treatment often associated with side-effects. Patients who may benefit from adjuvant chemotherapy can be identified by analyzing the genomic profile of the patients’ tumors using a molecular diagnostic test called the 21-gene assay (also known as Oncotype DX assay). However, the budgetary consequences of using Oncotype DX for this purpose in the Netherlands are currently unknown and, therefore, assessed using a health-economic model. The model compared the costs and consequences of using the Oncotype DX assay versus no molecular diagnostic testing and an alternative molecular diagnostic test called MammaPrint. The three diagnostic testing strategies resulted in different costs in terms of several different costing categories and were compared with one another. The total costs were lowest for the diagnostic strategy using the Oncotype DX assay, as it would result in fewer patients receiving adjuvant chemotherapy compared with no molecular diagnostic testing and MammaPrint. Implementing the Oncotype DX assay as a molecular diagnostic test can identify the right patient who benefits from chemotherapy (prevent over- and undertreatment) and lead to cost-savings, reducing the clinical and economic burden on the patient and Dutch healthcare system.

UNASSIGNED: To evaluate the cost-effectiveness of dapagliflozin added to standard of care (SoC) versus SoC in heart failure with reduced ejection fraction (HFrEF) and without type 2 diabetes mellitus (T2DM) patients from the Qatari healthcare perspective.
UNASSIGNED: A lifetime Markov model was developed to evaluate the cost-effectiveness of adding dapagliflozin to SoC based on the findings of Petrie et al. 2020, which were based on the DAPA-HF trial. The model was constructed based on four health states: \"alive with no event\", \"urgent visit for heart failure\", \"hospitalization for heart failure\", and \"dead\". The model considered 1,000 hypothetical HFrEF and without T2DM patients using 3-month cycles over a lifetime horizon. The outcome of interest was the incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year gained (QALY) and years of life lived (YLL). Utility and cost data were obtained from published sources. A scenario analysis was performed to replace the transition probabilities of events in people without T2DM with the transition probabilities of events irrespective of T2DM status, based on findings of the DAPA-HF trial. Sensitivity analyses were conducted to confirm the robustness of the conclusion.
UNASSIGNED: Adding dapagliflozin to SoC was estimated to dominate SoC alone, resulting in 0.6 QALY and 0.8 YLL, at a cost saving of QAR771 (USD211) per person compared with SoC alone, with total healthcare costs of QAR42,413 (USD 11,620) versus 43,184 (USD11,831) per person, respectively. When replacing the transition probabilities of events in people without T2DM with the transition probabilities of events in people irrespective of T2DM status, dapagliflozin was cost-effective at ICER of QAR5,212 (USD1,428) per QALY gained and QAR3,880 (USD1,063) per YLL. In the probabilistic sensitivity analysis, dapagliflozin combined with SoC was cost saving in over 49% of the cases and cost-effective in over 43% of the simulated cases against QALYs gained and YLL.
UNASSIGNED: Data from clinical trials were used instead of local data, which may limit the local relevance. However, evidence from the local Qatari population is lacking. Also, indirect costs were not included due to a paucity of available data.
UNASSIGNED: Adding dapagliflozin to SoC is likely to be a cost-saving therapy for patients with HFrEF and without T2DM in Qatar.
Heart failure with reduced ejection fraction is a type of heart failure characterized by left ventricular ejection fraction of 40% or less. Dapagliflozin is a novel therapy for this condition, which was initially designed to treat type 2 diabetes mellitus. It is unclear whether dapagliflozin is a cost-effective option for patients with heart failure with reduced ejection fraction and without type 2 diabetes. A lifetime Markov model was developed to evaluate the cost-effectiveness of adding dapagliflozin to standard of care from the Qatari healthcare perspective. Model results suggest that adding dapagliflozin to standard of care dominated standard of care alone, resulting in a gain of 0.8 years of life lived, a gain of 0.6 quality-adjusted life-years, and a cost saving of 211 United States dollars per person.
