Estimated Direct Costs of Renal Cancer by Stage of Disease at Diagnosis and Phase of Its Management: A Whole-Disease Model.

BACKGROUND: Renal cell carcinoma (RCC) is the seventh most common neoplasm in high-income countries. New clinical pathways have been developed to deal with this tumor, which includes costly drugs that pose an economic threat to the sustainability of healthcare services. This study provides an estimate of the direct costs of care for patients with RCC by stage of disease (early vs. advanced) at diagnosis, and disease management phase along the pathway recommended by local and international guidelines. MATERIALS AND METHODS: Considering the clinical pathway for RCC adopted in the Veneto region (north-east Italy) and the latest guidelines, we developed a very detailed "whole-disease" model that covers the probabilities of all potentially necessary diagnostic and therapeutic actions involved in the management of RCC. Based on the cost of each procedure according to the Veneto Regional Authority's official reimbursement tariffs, we estimated the total and average per-patient costs by stage of disease (early or advanced) and phase of its management. RESULTS: In the first year after diagnosis, the mean expected cost of a patient with RCC is €12,991 if it is localized or locally-advanced and reaches €40,586 if it is advanced. For early disease, the main cost is incurred by surgery, whereas medical therapy (first and second line) and supportive care become increasingly important for metastatic disease. CONCLUSION: It is crucially important to examine the direct costs of care for RCC, and to predict the burden on healthcare services of new oncological therapies and treatments, as the findings could be useful for policy-makers planning the allocation of resources.

Cost-effectiveness analysis of the new oncological drug durvalumab in Italian patients with stage III non-small cell lung cancer.

BACKGROUND: The monoclonal antibody durvalumab, an immune-checkpoint inhibitor (ICI) antiprogrammed death ligand 1 (PD-L1), is available for unresectable stage III NSCLC patients as consolidation therapy following induction chemoradiotherapy, with very promising overall survival (OS) and progression-free survial (PFS) results in registration trials. The purpose of this study was to provide policymakers with an estimate of the cost-effectiveness of durvalumab in the treatment of non-small cell lung cancer (NSCLC). METHODS: The study developed a Markov model covering a 5-year period to compare costs and outcomes of treating PD-L1 positive patients with or without durvalumab. We conducted a series of sensitivity analyses (Tornado analysis and Monte Carlo simulation) by varying some parameters to assess the robustness of our model and identify the parameters with the greatest impact on cost-effectiveness. RESULTS: Prior to the release of durvalumab, the management of NSCLC over a 5-year period cost €33 317 per patient, with an average life expectancy of 2.01 years. After the introduction of the drug, this increased to €37 317 per patient, with an average life expectancy of 2.13 years. Treatment with durvalumab led to an incremental cost-effectiveness ratio (ICER) of €35 526 per year. OS is the variable that contributes the most to the variability of the ICER. CONCLUSIONS: The study observed that durvalumab is a cost-effective treatment option for patients with unresectable stage III NSCLC.

Exploring Anatomo-Morphometric Characteristics of Infrapatellar, Suprapatellar Fat Pad, and Knee Ligaments in Osteoarthritis Compared to Post-Traumatic Lesions.

Several studies have investigated cartilage degeneration and inflammatory subchondral bone and synovial membrane changes using magnetic resonance (MR) in osteoarthritis (OA) patients. Conversely, there is a paucity of data exploring the role of knee ligaments, infrapatellar fat pad (IFP), and suprapatellar fat pad (SFP) in knee OA compared to post-traumatic cohorts of patients. Therefore, the aim of this study was to analyze the volumetric and morphometric characteristics of the following joint tissues: IFP (volume, surface, depth, femoral and tibial arch lengths), SFP (volume, surface, oblique, antero−posterior, and cranio−caudal lengths), anterior (ACL) and posterior cruciate ligament (PCL) (volume, surface, and length), and patellar ligament (PL) (volume, surface, arc, depth, and length). Eighty-nine MR images were collected in the following three groups: (a) 32 patients with meniscal tears, (b) 29 patients with ACL rupture (ACLR), and (c) 28 patients affected by end-stage OA. Volume, surface, and length of both ACL and PCL were determined in groups a and c. A statistical decrease of IFP volume, surface, depth, femoral and tibial arch lengths was found in end-stage OA compared to patients with meniscal tear (p = 0.002, p = 0.008, p < 0.0001, p = 0.028 and p < 0.001, respectively) and patients with ACLR (p < 0.0001, p < 0.0001, p = 0.008 and p = 0.011, respectively). An increment of volume and surface SFP was observed in group b compared to both groups a and c, while no differences were found in oblique, antero−posterior, and cranio−caudal lengths of SFP among the groups. No statistical differences were highlighted comparing volume, surface, arc, and length of PL between the groups, while PL depth was observed to be decreased in end-OA patients compared with meniscal tear patients (p = 0.023). No statistical differences were observed comparing ACL and PCL lengths between patients undergoing meniscectomy and TKR. Our study confirms that IFP MR morphometric characteristics are different between controls and OA, supporting an important role of IFP in OA pathology and progression in accordance with previously published studies. In addition, PL depth changes seem to be associated with OA pathology. Multivariate analysis confirmed that OA patients had a smaller IFP compared to patients with meniscal tears, confirming its involvement in OA.

Do Synovial Inflammation and Meniscal Degeneration Impact Clinical Outcomes of Patients Undergoing Arthroscopic Partial Meniscectomy? A Histological Study.

The menisci exert a prominent role in joint stabilization and in the distribution of mechanical loading. Meniscal damage is associated with increased risk of knee OA. The aim of this study was to characterize the synovial membrane and meniscal tissues in patients undergoing arthroscopic partial meniscectomy for meniscal tear and to evaluate association with clinical outcomes. A total of 109 patients were recruited. Demographic and clinical data were collected. Visual Analogic Scale (VAS) measuring pain and Knee injury and Osteoarthritis Outcome Score (KOOS) were recorded at baseline and at 2-years follow-up. Histological and immunohistochemical characterizations were performed on synovial membranes and meniscal tissues. More than half of the patients demonstrated synovial mononuclear cell infiltration and hyperplasia. Synovial fibrosis was present in most of the patients; marked vascularity and CD68 positivity were observed. Inflammation had an impact on both pain and knee symptoms. Patients with synovial inflammation had higher values of pre-operative VAS and inflammation. Higher pre-operative pain was observed in patients with meniscal MMP-13 production. In conclusion, multivariate analysis showed that synovial inflammation was associated with pre-operative total KOOS scores, knee symptoms, and pain. Moreover, meniscal MMP-13 expression was found to be associated with pre-operative pain in multivariate analysis. Thus, targeting inflammation of the synovial membrane and meniscus might reduce clinical symptoms and dysfunction at the time of surgery.

Health and healthcare variables associated with Italy's excess mortality during the first wave of the COVID-19 pandemic: An ecological study.

BACKGROUND: Healthcare factors have strongly influenced the propagation of COVID-19. This study aims to examine whether excess mortality during the first phase of the COVID-19 outbreak in Italy was associated with health, healthcare, demographic, and socioeconomic, provincial-level indicators. METHODS: This ecological study concerns the raw number of deaths reported from February 1 to April 30, 2020 and the mean number of deaths occurred during the same months from 2015 to 2019, per province. Information on socioeconomic factors and healthcare settings was extracted from updated databases on the Italian National Institute of Statistics (ISTAT) website. A multivariate model and four multilevel models were constructed to test the association between excess mortality and the analysed indicators across 107 Italian provinces. RESULTS: The hospitalization rate in long-term care wards and the cardiovascular disease mortality rate correlate positively with excess mortality (p <0.05), while higher densities of licensed physicians and of general practitioners are associated with lower excess mortality (p <0.05). After controlling for the COVID-19 cumulative incidence in each province, only the density of licensed physicians remains negatively associated with excess mortality (p <0.01). CONCLUSION: Some health and healthcare variables (in particular, the density of physicians) are strongly associated with excess mortality during the first wave of the COVID-19 pandemic in Italy and should be targeted to increase the resilience of health systems.

Effectiveness of Repair of Aortic Coarctation in Neonates: A Long-Term experience.

To evaluate early and long-term results of surgical treatment of aortic coarctation (CoAo) in neonates. This is a retrospective clinical review of neonates with CoAo, who underwent surgery between 1995 and 2019. Data were retrieved from our institutional database, to identify preoperative and postoperative characteristics. Statistical analysis was performed by means of relative risk ratio and Cox and logistic multivariate analysis. 218 consecutive neonates (M/F: 129/89, median age 11 days, IQR 7-17 days) were included; 202 (92.7%) had a left thoracotomy; 178 underwent extended end-to-end anastomosis (EEEA, 81.6%). Hypoplastic aortic arch (HAA) was present in 102 patients (46.8%); complex cardiac anomalies in 85 (39%). Significant postoperative complications occurred in 20 (9.2%). Thirty-day mortality was 2.3% (most in complex types). At a median follow-up of 10.4 years (IQR 5.6-15.0 years; FU completeness 95.9%), there were 8 late deaths (3.7%), all associated to complex CoAo. Among 196 survivors, 177 (93.2%) were in NYHA class I; re-interventions on aortic arch occurred in 9.2% (2.0% were surgical). Freedom from mortality and re-intervention on aorta at 10 years were 94.3% and 96.7%, respectively. Surgical repair of CoAo in newborns without CPB in our series was safe and low-risk, with excellent early and late outcomes.

Estimated direct costs of non-small cell lung cancer by stage at diagnosis and disease management phase: A whole-disease model.

BACKGROUND: Non-small cell lung cancer (NSCLC) is the first cause of cancer-related death among men and the second among women worldwide. It also poses an economic threat to the sustainability of healthcare services. This study estimated the direct costs of care for patients with NSCLC by stage at diagnosis, and management phase of pathway recommended in local and international guidelines. METHODS: Based on the most up-to-date guidelines, we developed a very detailed "whole-disease" model listing the probabilities of all potentially necessary diagnostic and therapeutic actions involved in the management of each stage of NSCLC. We assigned a cost to each procedure, and obtained an estimate of the total and average per-patient costs of each stage of the disease and phase of its management. RESULTS: The mean expected cost of a patient with NSCLC is 21,328 € (95% C.I. -20 897-22 322). This cost is 16 291 € in stage I, 19530 € in stage II, 21938 € in stage III, 22175 € in stage IV, and 28 711 € for a Pancoast tumor. In the early stages of the disease, the main cost is incurred by surgery, whereas in the more advanced stages radiotherapy, medical therapy, treatment for progressions, and supportive care become variously more important. CONCLUSIONS: An estimation of the direct costs of care for NSCLC is fundamental in order to predict the burden of new oncological therapies and treatments on healthcare services, and thus orient the decisions of policy-makers regarding the allocation of resources. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: The high costs of surgery make the early stages of the disease no less expensive than the advanced stages. WHAT THIS STUDY ADDS: An estimation of the direct costs of care is fundamental in order to orient the decisions of policy-makers regarding the allocation of resources.

Demographic and socio-economic factors, and healthcare resource indicators associated with the rapid spread of COVID-19 in Northern Italy: An ecological study.

BACKGROUND: COVID-19 rapidly escalated into a pandemic, threatening 213 countries, areas, and territories the world over. We aimed to identify potential province-level socioeconomic determinants of the virus's dissemination, and explain between-province differences in the speed of its spread, based on data from 36 provinces of Northern Italy. METHODS: This is an ecological study. We included all confirmed cases of SARS-CoV-2 reported between February 24th and March 30th, 2020. For each province, we calculated the trend of contagion as the relative increase in the number of individuals infected between two time endpoints, assuming an exponential growth. Pearson's test was used to correlate the trend of contagion with a set of healthcare-associated, economic, and demographic parameters by province. The virus's spread was input as a dependent variable in a stepwise OLS regression model to test the association between rate of spread and province-level indicators. RESULTS: Multivariate analysis showed that the spread of COVID-19 was correlated negatively with aging index (p-value = 0.003), and positively with public transportation per capita (p-value = 0.012), the % of private long-term care hospital beds and, to a lesser extent (p-value = 0.070), the % of private acute care hospital beds (p-value = 0.006). CONCLUSION: Demographic and socioeconomic factors, and healthcare organization variables were found associated with a significant difference in the rate of COVID-19 spread in 36 provinces of Northern Italy. An aging population seemed to naturally contain social contacts. The availability of healthcare resources and their coordination could play an important part in spreading infection.

Midshaft Clavicle Fractures Treated Nonoperatively Using Figure-of-Eight Bandage: Are Fracture Type, Shortening, and Displacement Radiographic Predictors of Failure?

As there are no clear and unique radiographic predictors of healing disturbances for acute midshaft clavicle fractures, their treatment is still controversial. The aim of the study was to evaluate in midshaft clavicle fractures treated nonoperatively if fracture type (FT), shortening, and displacement, assessed before and after figure-of-eight bandage (F8-B) application, could be considered prognostic factors of delayed union and nonunion. One hundred twenty-two adult patients presenting a closed displaced midshaft clavicle fracture, managed nonoperatively with an F8-B, were enrolled. FT, initial shortening (IS), and initial displacement (ID) were radiographically evaluated at diagnosis, and both residual shortening (RS) and displacement (RD) were measured after F8-B application. The patients were followed up 1, 3, 6, and 12 months post-injury. Multivariate statistical analysis was performed. RD should be considered as radiological predictor of sequelae. Further, an RD equal to 104% of clavicle width was identified as an optimal cut-off point to distinguish between healed and unhealed fractures, and 140% between delayed union and nonunion. Our data pointed out the effectiveness of the F8-B in reducing fracture fragments and restoring clavicular length. In midshaft clavicle fractures of adults, fracture comminution and clavicular shortening did not influence bone healing. On the contrary, RD has been shown as the most likely predictor of both delayed union and nonunion.

Infrapatellar Fat Pad Gene Expression and Protein Production in Patients with and without Osteoarthritis.

Osteoarthritis (OA) is one of the most common joint disorders. Evidence suggests that the infrapatellar fat pad (IFP) is directly involved in OA pathology. However, a comparison between OA versus non-OA IFP is still missing. Thus, the aim of this study was to compare IFP molecular, adipocytes and extracellular matrix characteristics of patients affected by OA, and patients undergoing anterior cruciate ligament (ACL) reconstruction. We hypothesized that not only inflammation but also changes in adipocytes and extracellular matrix (ECM) composition might be involved in OA pathogenesis. Fifty-three patients were enrolled. IFP biopsies were obtained, evaluating: (a) lymphocytic infiltration and vascularization; (b) adipocytes area and number; (c) adipo-cytokines and extracellular matrix gene expression levels; (d) IL-6 and VEGF protein production; (e) collagen fibers distribution. OA IFP was more inflamed and vascularized compared to ACL IFP. OA IFP adipocytes were larger and numerically lower (1.3-fold) than ACL IFP adipocytes. An increase of gene expression of typical white adipose tissue genes was observed in OA compared to ACL IFP. Collagen-types distribution was different in the OA IFP group compared to controls, possibly explaining the change of the biomechanical characteristics found in OA IFP. Statistical linear models revealed that the adipocyte area correlated with BMI in the OA group. In conclusion, inflammation and fibrotic changes of OA IFP could represent novel therapeutic targets to counteract OA.

Estimation of direct costs of melanoma in the Veneto Region: a budget assessment and cost-consequence analysis.

BACKGROUND: While many evidence-based pathways have been introduced to drive quality improvements in cancer care, most of these do not include evidence about their affordability. The main aim of this study was to provide an estimation of the overall budget to cover all the needs of melanoma patients in Veneto Region, managed according to the clinical pathway defined by the Rete Oncologica Veneta. A second objective is to conduct a cost-consequence analysis, comparing two different treatments. METHODS: A very detailed whole-disease model was developed describing the patient's pathway from diagnosis through the first year of follow-up. Each procedure involved in the model was associated with a likelihood measure and a cost. The model can be used to estimate the expected direct costs associated with melanoma. RESULTS: We can observe that 0 and I stage, despite accounting for a huge percentage of new melanoma cases are characterized by a small percentage of the total costs. Stage III can be considered as the most expensive stage accounting for 54% of the total costs with a 12% of patients. Finally, the stage IV patients, although very few accounts for almost the 7% of the total costs. Regarding the cost-consequence analysis, it was estimated that the therapies introduced in 2016 led to an approximately 14% increase in the total costs. CONCLUSIONS: Modeling a clinical pathway with a high level of detail enables to identify the main sources of spending. The consequent analysis can thus help policymakers to plan the future resources allocation.

Cost-effectiveness of a melanoma screening programme using whole disease modelling.

OBJECTIVE: To assess the potential impact of a melanoma screening programme, compared with usual care, on direct costs and life expectancy in the era of targeted drugs and cancer immunotherapy. METHODS: Using a Whole Disease Model approach, a Markov simulation model with a time horizon of 25 years was devised to analyse the cost-effectiveness of a one-time, general practitioner-based melanoma screening strategy in the population aged over 20, compared with no screening. The study considered the most up-to-date drug therapy and was conducted from the perspective of the Veneto regional healthcare system within the Italian National Health Service. Only direct costs were considered. Sensitivity analyses, both one-way and probabilistic, were performed to identify the parameters with the greatest impact on cost-effectiveness, and to assess the robustness of our model. RESULTS: Over a 25-year time horizon, the screening intervention dominated usual care. The probabilistic sensitivity analyses confirmed the robustness of these findings. The key drivers of the model were the proportion of melanomas detected by the screening procedure and the adherence of the target population to the screening programme. CONCLUSIONS: The screening programme proved to be a dominant option compared with usual care. These findings should prompt serious consideration of the design and implementation of a regional or national melanoma screening strategy within a National Health Service.

Estimation of Direct Melanoma-related Costs by Disease Stage and by Phase of Diagnosis and Treatment According to Clinical Guidelines.

Cutaneous melanoma is a major concern in terms of healthcare systems and economics. The aim of this study was to estimate the direct costs of melanoma by disease stage, phase of diagnosis, and treatment according to the pre-set clinical guidelines drafted by the AIOM (Italian Medical Oncological Association). Based on the AIOM guidelines for malignant cutaneous melanoma, a highly detailed decision-making model was developed describing the patient's pathway from diagnosis through the subsequent phases of disease staging, surgical and medical treatment, and follow-up. The model associates each phase potentially involving medical procedures with a likelihood measure and a cost, thus enabling an estimation of the expected costs by disease stage and clinical phase of melanoma diagnosis and treatment according to the clinical guidelines. The mean per-patient cost of the whole melanoma pathway (including one year of follow-up) ranged from €149 for stage 0 disease to €66,950 for stage IV disease. The costs relating to each phase of the disease's diagnosis and treatment depended on disease stage. It is essential to calculate the direct costs of managing malignant cutaneous melanoma according to clinical guidelines in order to estimate the economic burden of this disease and to enable policy-makers to allocate appropriate resources.

SOGS-RA gambling scores and substance use in adolescents.

Background and aims There is a well-established association between pathological gambling and substance use disorders in adolescents. The aim of this study was to shed light on the association between adolescents' different levels of involvement in gambling activities and substance use (smoking tobacco and cannabis and drinking alcoholic beverages), based on a large sample. Methods A survey was conducted in 2013 on 34,746 students attending 619 secondary schools, who formed a representative sample of the Italian 15- to 19-year-old population. The prevalence of different categories of gamblers was estimated by age group and gender. A multiple correspondence analysis (CA) was conducted to explain the multivariate associations between substance use and gambling. Results The prevalence of problem gambling was 2.7% among the 15- to 17-year-olds, and rose to 3.6% among the 18- and 19-year-olds. Multiple CA revealed that, even when it does not reach risk-related or problem levels, gambling is associated with the use of alcohol and tobacco. In particular, the analysis showed that non-problem gambling levels were associated with alcohol and tobacco use at least once in the previous month, and that higher-risk gambling levels related to the use of cannabis and episodes of drunkenness at least once in the previous month. Conclusion This study found that any gambling behavior, even below risk-related or problem levels, was associated with some degree of substance use by youths, and that adolescents' levels of gambling lay along a continuum of the categories of substance use.
