BACKGROUND: Myasthenia gravis (MG) is a rare autoimmune disorder with significant clinical implications, including life-threatening myasthenic crises and exacerbations. Understanding real-world treatment patterns, especially associated direct medical costs, is essential for the effective management of healthcare delivery. METHODS: We conducted a descriptive cohort study using health administrative claims data from the Czech Republic covering more than 1,500 prevalent MG patients. Data were analysed for healthcare resource utilization, medication costs, and hospitalization rates related to MG and its complications. RESULTS: Acetylcholine inhibitors and corticosteroids were widely prescribed, with 91.1% and 75.2% of patients receiving them at least once, respectively. Immunosuppressive therapy was given to 45.2% of patients. Myasthenic crises occurred in 2% of patients, with a mean hospitalization cost of 21,020 EUR, while exacerbations occurred in 9.2% of patients, with lower costs (5,951 EUR per hospitalization). Outpatient intravenous immunoglobulin and plasma exchange therapies incurred additional costs of 20,700 EUR and 18,206 EUR per person-year, respectively. The mean total cost per patient-year was 1,271 EUR, with significant cost differences among patients with different treatment patterns. CONCLUSION: This study offers real-world insights into the treatment patterns and associated direct medical costs of MG in the Czech Republic. Myasthenic crises and exacerbations pose considerable cost burdens, while outpatient therapies and common pharmacotherapies are less costly. These findings are vital for healthcare planning, economic evaluation, and resource allocation, potentially leading to enhanced patient care and outcomes.

BACKGROUND: Part of the current stereotactic arrythmia radioablation (STAR) workflow is transfer of findings from the electroanatomic mapping (EAM) to computed tomography (CT). Here, we analyzed inter- and intraobserver variation in a modified EAM-CT registration using automatic registration algorithms designed to yield higher robustness. MATERIALS AND METHODS: This work is based on data of 10 patients who had previously undergone STAR. Two observers participated in this study: (1) an electrophysiologist technician (cardiology) with substatial experience in EAM-CT merge, and (2) a clinical engineer (radiotherapy) with minimum experience with EAM-CT merge. EAM-CT merge consists of 3 main steps: segmentation of left ventricle from CT (CT LV), registration of the CT LV and EAM, clinical target volume (CTV) delineation from EAM specific points. Mean Hausdorff distance (MHD), Dice Similarity Coefficient (DSC) and absolute difference in Center of Gravity (CoG) were used to assess intra/interobserver variability. RESULTS: Intraobserver variability: The mean DSC and MHD for 3 CT LVs altogether was 0.92 ± 0.01 and 1.49 ± 0.23 mm. The mean DSC and MHD for 3 CTVs altogether was 0,82 ± 0,06 and 0,71 ± 0,22 mm. Interobserver variability: Segmented CT LVs showed great similarity (mean DSC of 0,91 ± 0,01, MHD of 1,86 ± 0,47 mm). The mean DSC comparing CTVs from both observers was 0,81 ± 0,11 and MHD was 0,87 ± 0,45 mm. CONCLUSIONS: The high interobserver similarity of segmented LVs and delineated CTVs confirmed the robustness of the proposed method. Even an inexperienced user can perform a precise EAM-CT merge following workflow instructions.

BACKGROUND: Obstructive sleep apnea (OSA) is a risk factor for several diseases and is correlated with other non-medical consequences that increase the disease's clinical and economic burden. However, OSA's impact is highly underestimated, also due to substantial diagnosis gaps. OBJECTIVE: This study aims at assessing the economic burden of OSA in the adult population in Italy by performing a cost-of-illness analysis with a societal perspective. In particular, we aimed at estimating the magnitude of the burden caused by conditions for which OSA is a proven risk factor. METHODS: A systematic literature review on systematic reviews and meta-analyses, integrated by expert opinion, was performed to identify all clinical and non-clinical conditions significantly influenced by OSA. Using the Population Attributable Fraction methodology, a portion of their prevalence and costs was attributed to OSA. The total economic burden of OSA for the society was estimated by summing the costs of each condition influenced by the disease, the costs due to OSA's diagnosis and treatment and the economic value of quality of life lost due to OSA's undertreatment. RESULTS: Twenty-six clinical (e.g., diabetes) and non-clinical (e.g., car accidents) conditions were found to be significantly influenced by OSA, contributing to an economic burden ranging from €10.7 to €32.0 billion/year in Italy. The cost of impaired quality of life due to OSA undertreatment is between €2.8 and €9.0 billion/year. These costs are substantially higher than those currently borne to diagnose and treat OSA (€234 million/year). CONCLUSIONS: This study demonstrates that the economic burden due to OSA is substantial, also due to low diagnosis and treatment rates. Providing reliable estimates of the economic impact of OSA at a societal level may increase awareness of the disease burden and help to guide evidence-based policies and prioritisation for healthcare, ultimately ensuring appropriate diagnostic and therapeutic pathways for patients.

PURPOSE: The aim of the present study was to assess, by using a cost-benefit analysis, the net monetary benefit (NMB) of bariatric surgery compared with diet (including physical exercise) for obese patients, from both an Italian payer perspective and the broader societal perspective. METHODS: The study considered the following groups of patients: (1) patients with a body mass index (BMI) ≥40 kg/m2 without complications + patients with BMI ≥35 kg/m2 with complications; (2) patients with BMI ≥35 kg/m2 and diabetes; and (3) patients with BMI ranging from 30 to 35 kg/m2 and diabetes. A Markov model was developed to project the lifetime health outcomes (life years and quality-adjusted life years [QALYs]) and costs associated with bariatric surgery and diet for the considered groups of patients. The clinical effectiveness of each strategy was based on the likelihood of experiencing cardiovascular events or events related to the presence of diabetes. Data on clinical effectiveness, quality of life, productivity losses, and out-of-pocket costs were mainly derived from the literature; direct costs were obtained from official tariffs or the literature. Different scenarios were considered for the analyses in addition to the base case. According to both perspectives considered, the NMB was calculated by first assuming a willingness-to-pay threshold (30,000€ per QALY), then converting health benefits (QALYs) into the common monetary metric (ie, the euro). NMB was calculated as follows: (incremental benefit × willingness-to-pay - incremental cost). FINDINGS: For all the scenarios and groups of patients considered, the NMB of bariatric surgery versus diet, on a lifetime horizon, from the payer perspective was positive and ranged from 54,647€ to 122,960€; it varied between 141,192€ and 380,286€ from the societal perspective. In the former case, the NMB turns positive after 3-4 years, indicating that bariatric surgery may be a worthy investment also in the short run for the National Health Service; in the latter case, for a time horizon longer than 2-3 years, the surgical option begins to show advantages for the whole society. IMPLICATIONS: Despite its defined cost-effectiveness, bariatric surgery is under-diffused because the initial investment for the technology is often considered a barrier. The cost-benefit analysis showed that bariatric surgery, compared with diet, may be a worthwhile technology for obese patients in Italy from both a payer perspective and the broader societal perspective.
