[The care pathway of patients with diffuse large B-cell lymphoma described through Italian administrative healthcare data.] / Il percorso di cura dei pazienti con linfoma diffuso a grandi cellule B descritto attraverso i dati amministrativi.

INTRODUCTION: The diffuse large B-cell lymphoma (Dlbcl) is the most common non-Hodgkin lymphoma and at highest incidence among the elderly. Despite the improved outcomes of patients treated with the first-line (1L) standard of care until the end of 2022, composed by rituximab and polychemotherapy (R-Chop), during the last 20 years, the rate of relapsed and refractory Dlbcl (rrDlbcl) remains elevated. This study has identified and analyzed patients newly diagnosed with Dlbcl and treated with 1L, from the perspective of the Italian National Health Service (Ssn). METHODS: From the administrative database of Fondazione Ricerca e Salute (ReS) including ~5.5 million inhabitants/year in Italy, adults with a new in-hospital Dlbcl diagnosis (index date) and treated with 1L in 2018, 2019, 2020 and 2021 were identified and characterized in terms of demographics and comorbidities during a period (from 4 to 8 years) preceding index date. From 1 to 4 years following index date (follow-up), overall survival (Kaplan-Meier curves), percentage distribution of patients by line of therapy including dispensation/administration of chemo-immunotherapy, hemopoietic stem cell transplantation (Hsct), and direct healthcare costs charge to the Ssn, were evaluated. RESULTS: Overall, from the ReS database, 206 patients newly diagnosed with Dlbcl and treated with 1L from 2018 to 2021 in Italy (incidence from 0.9 to 1.7 x100,000 adult inhabitants) were identified. They were mainly older (median age 68 [56; 75] years), males (56%) and affected by ≥2 comorbidities (52%), mostly cardiometabolic. During 4 years of follow-up, 56% of cases in 2018 survived. During the first follow-up year: 73%, 80%, 100% and 35% of cases in 2018, 2019, 2020 and 2021, respectively, received a 2L; 42% and 64% of cases in 2018 and 2020, respectively, received a 3L. At least one Hsct was found as a 2L among cases in 2018, 2020 and 2021. On average, each patient newly diagnosed with Dlbcl and treated with 1L from 2018 to 2021 caused a total expenditure directly charged to the Ssn ranging from € 20,000 to € 30,000 during the first follow-up year (chemo-immunotherapy accounted for 40-53%), which reduced with time in favor of other drugs and Hsct. CONCLUSIONS: This analysis confirms the high rate of rrDlbcl and the high economic impact charged to the SSN to support first the chemo-immunotherapy, then the chronic care and the absence of standardized further lines of therapy for patients with rrDlbcl.

[The population affected by neovascular age-related macular degeneration and treated with anti-Vegf through Italian administrative healthcare data.] / La popolazione con degenerazione maculare neovascolare correlata all'età trattata con anti-Vegf attraverso i dati amministrativi sanitari.

INTRODUCTION: The neo-vascular age-related macular degeneration (nAmd) is a frequent cause of vision loss, although the intravitreal (Ivt) injections of anti-Vegf (vascular endothelial growth factor) have improved functional outcomes. This study has assessed the healthcare and economic burden on the Italian national health service (Inhs) for patients with nAmd and new users of anti-Vegf. METHODS: From the database of Fondazione Ricerca e Salute (ReS), people aged ≥55 and with an in-hospital diagnosis of nAmd and/or an injection of anti-Vegf (aflibercept, ranibizumab, pegaptanib; index date) in 2018 are selected. Those with other conditions treated with anti-Vegf and with an Ivt injection before 2018 are excluded. New users of anti-Vegf are analyzed by sex, age, comorbidities, Ivt administrations, switch of anti-Vegf, local outpatient specialist services (with some focuses) and direct healthcare costs charged to the Inhs Results. In 2018, of 8125 inhabitants aged ≥55 with nAmd (4.6x1000 inhab.; mean age 76±9; F: 50%), 1513 (19%) are new users of Ivt anti-Vegf (mean age 74±9), whose incidence (0.9x1000) increased with age until 84 years old. A proportion of 60.7% had ≥2 comorbidities (mainly hypertension, dyslipidemia and diabetes). Within the 2nd follow-up year, only 598 patients are still treated (60% were lost). On average, 4.8 Ivt injections in the first and 3.1 in the second year are registered. On average, the total cost charged to the Inhs per new user of anti-Vegf was € 6726 (Ivt anti-Vegf accounted for the 76%) and € 3282 (hospitalizations for causes different from nAmd accounted for the 47%), during the first and the second year, respectively. CONCLUSIONS: This analysis suggests that in Italy people with nAmd and new users of anti-Vegf are elderly, affected by many comorbidities, treated with Ivt anti-VEGF less than what is required and authorized to achieve a benefit, undergo very few follow-up outpatient specialist visits and tests and, within the 2nd year, their hospitalizations for causes different from nAmd mainly weighs on the total expenditure charged to the Inhs.

Do more targets allow more cancer treatments, or not?

The three current oncology models (histological, agnostic and mutational) mainly differ in clinical, technological and organisational aspects, leading to different regulatory procedures and implications in antineoplastic therapy access by patients. Within the histological and agnostic models, Regulatory Agencies authorise target therapies and define their price, reimbursement, prescription and access based on results from clinical trials including patients affected by the same tumour (histological) or subjects with specific genetic mutations regardless of the tumour site or the histology (agnostic). The mutational model has been developed to identify specific actionable molecular alterations found by next-generation sequencing test-based large platforms on solid and liquid biopsies. Nevertheless, due to the highly uncertain efficacy and possible toxicity of drugs tested within this model, regulatory procedures based on histological or agnostic oncology cannot be followed. Multidisciplinary skills are required (e.g. the molecular tumour board's (MTB) representatives) to identify the best association between the genomic profile and the drug planned to be used, but quality requirements, practices and procedures of these discussions still need to be standardised. Real-world evidence from clinical practice (i.e. genomic findings, clinical data and MTBs' choices) lacks, therefore, it is urgently needed as opposed to limited findings from clinical trials. A potential solution for an appropriate access to the therapy chosen by the mutational model can be the indication-value-based sub iudice procedure of authorisation. The access to therapies suggested by extensive molecular profiling could be easily implementable within the Italian national health system, thanks to the existing regulatory procedures, i.e. the managed-entry agreements and the antineoplastic drug monitoring registries, alongside those granted by conventional studies (phase I, II, III, IV) conducted according to the histological and agnostic models.

Acute myeloid leukemia: Incidence, transplantation and survival through Italian administrative healthcare data.

OBJECTIVE: To identify newly diagnosed patients with acute myeloid leukemia in 2017 treated with intensive chemotherapy or unfit for intensive chemotherapy, and to assess their probability of receiving allogeneic stem cell transplantation and survival, from the Italian National Health Service perspective. PATIENTS AND METHODS: From the Ricerca e Salute database, adults with an in-hospital diagnosis of acute myeloid leukemia (International Classification of Disease-9th version-Clinical Modification code 205.0x) in 2017 (index date), without any identifying acute myeloid leukemia criteria within the preceding year, were selected. Among them, subjects treated with intensive chemotherapy (chemotherapy during an overnight hospitalization) within one year after index date were identified. The remaining were considered unfit for intensive chemotherapy. Gender, age and comorbidities were described. Within the follow-up period, probabilities of in-hospital allogeneic stem cell transplantation and overall survival were assessed through Kaplan Meier analyses. RESULTS: From 4,840,063 beneficiaries of the Italian National Health Service, 368 newly acute myeloid leukemia diagnosed adults (9.0 *100,000) were selected. Males comprised 57%. Mean age was 68±15. There were 197 patients treated with intensive chemotherapy. The remaining 171 unfit for intensive chemotherapy were older (72±14) and with more comorbidities (e.g. hypertension, chronic lung diseases and chronic kidney disease). Only patients treated with intensive chemotherapy underwent an allogeneic stem cell transplantation (41; 33%) during the one year after the index date. Within the first and second follow-up year, respectively: 41.1% and 26.9% of subjects treated with intensive chemotherapy (144) survived (median survival time: 7.8 months); 25.7% and 18.7% of those unfit for intensive chemotherapy (139) survived (1.2 months). Difference was significant (p<0.0001). Within one and two years after transplantation (41 patients), 73.5% and 67.3% of subjects survived, respectively. CONCLUSION: This study, by showing the incidence of acute myeloid leukemia in Italy in 2017, the proportion of patients treated with intensive chemotherapy from the new diagnosis, the use of allogeneic stem cell transplantation and two-year survival, integrated evidence on large and unselected populations and may help to improve treatment strategies of older acute myeloid leukemia patients.

[Occurrence of cardiovascular events within a large population of patients affected by rheumatoid arthritis with or without diabetes.] / Sviluppo di eventi cardiovascolari in un'ampia popolazione di pazienti affetti da artrite reumatoide con o senza diabete.

INTRODUCTION: Rheumatoid arthritis (Ra) and diabetes are often associated with chronic multimorbidity and share the high risk of development of major cardiovascular events (Mace). This study aimed to identify and analyse patients with only Ra, Ra + diabetes, and only diabetes, in terms of comorbidities and new occurrence of Cv events, from the perspective of the Italian national health service (Inhs). METHODS: Starting from the Fondazione ricerca e salute (ReS)'s database, through the record linkage of administrative healthcare data, cohorts with only Ra, Ra + diabetes and only diabetes have been selected, characterized (age and sex), and analysed by comorbidity (depression, dyslipidemia, hypertension, hemorrhagic stroke and ischemic stroke/transient ischemic attack - Tia, coronary artery disease - Cad, heart failure - Hf, chronic liver disease, periphery artery disease - Pad, chronic kidney disease, asthma/chronic obstructive pulmonary disease - Copd, neoplasia) and by new Cv events (Hf, Cad and ischemic stroke/Tia) within two follow-up years (Kaplan-Meier curves). A logistic regression model defined contribution and type of association of some variables on new Cv events. RESULTS: In 2018, from 5.375.531 Inhs beneficiaries in the ReS database, 13.698 (0.25%) were affected by only Ra, 1728 (0.03%) by Ra + diabetes, 347,659 (6.8%) by only diabetes. The only Ra cohort was composed by more females, younger and with less comorbidities patients. Proportions of 79.3%, 70.8% and 38.5% of patients with Ra + diabetes, only diabetes and only Ra were affected by 2 to ≥4 comorbidities: among patients with Ra + diabetes, comorbidities showed the highest frequencies, mainly hypertension, dyslipidemia and asthma/Copd. Within two follow-up years, about 8% of patients with diabetes with/without Ra developed a new Cv event (vs 3% with only Ra). The presence of Ra/diabetes or Ra + diabetes, male sex, older age and comorbidities of interest resulted significantly (p<0.01) associated with a higher Cv risk. CONCLUSIONS: Comorbidities and the co-presence of diabetes in patients with Ra determine a complicated framework with high risk of Cv events. It is worthy include more complex patients in clinical trials, in order to generate evidence useful for even more multidisciplinary medical teams.

How many and who are patients with heart failure eligible to SGLT2 inhibitors? Responses from the combination of administrative healthcare and primary care databases.

BACKGROUND: Recent successful findings (i.e. DAPA-HF trial) in patients with heart failure (HF) with/without diabetes treated with sodium-glucose co-transporter inhibitors (SGLT2-I) have fostered real-world data analyses. Fondazione Ricerca e Salute's (ReSD) administrative and Health Search's (HSD) primary healthcare databases were combined in the ReS-HS DB Consortium, to identify and characterize HF-patients eligible to SGLT2-I, and assess their costs charged to the Italian National Health Service (INHS). METHODS AND RESULTS: Eligibility to SGLT2-I was HF diagnosis, age ≥ 18 years, reduced (≤40%) ejection fraction (HFrEF) and glomerular filtration rate (GFR) ≥30 ml/min. The HSD, including 13,313 HF-patients (1.5% of the total HSD population) was used to develop and test the algorithms for imputing HFrEF and GFR ≥ 30 ml/min, based on a set of covariates, to the ReSD, including 67,369 (1.5% of the total ReSD population). Subjects eligible to SGLT2-I were 2187 in HSD (61.1% of HFrEF); after the imputation, 15,145 in ReSD (58.8% of HFrEF). Prevalence of eligibility to SGLT2-I was higher in males then in females and increased with age; diabetic patients were 44.3% and 33.4% of HSD and ReSD populations eligible to SGLT2-I, respectively. Estimated from ReSD, the mean annual cost charged to the INHS per patient with HF eligible to SGLT2-I was €7122 (68% due to hospitalizations). CONCLUSIONS: Approximately 20% of patients with HF was eligible to SGLT2-I. Real-world data can identify, quantify and characterize patients eligible to SGLT2-Is and assess related costs for the health care system, thus providing useful information to Regulatory Decision makers.

[A view of care pathways approved by Italian Regions, to face the challenge of the community-based healthcare: a quali-quantitative analysis of the Pdta Net database.] / Conoscere i percorsi diagnostico-terapeutici assistenziali (Pdta) regionali approvati in Italia per affrontare il cambiamento della assistenza di prossimità: analisi quali-quantitativa del database Pdta Net.

INTRODUCTION: The adoption of a Care Pathway (CP) allows the healthcare management of patients suffering from high-epidemiological impact chronic diseases. The continuity of care of these patients is one of the main purposes of the community-based healthcare reform, foreseen in the 6th Mission of the National recovery and resilience plan. Fondazio-ne Ricerca e Salute (ReS) collects and analyses regional CPs approved in Italy, through the Pdta Net database. METHODS: Fondazione ReS has retrieved all the CPs approved by Italian Regions and Autonomous provinces until 12/31/2021 within institutional websites, through specific keywords. The quali- and quantitative analysis of CPs was based on the approving Region, the publication year, the disease (distinguishing between high-epidemiological impact chronic diseases and rare conditions) and clinical area. Following the 5-year experience gained by Fondazione ReS in terms of CPs' aims and organization for the full realization of an evidence-based healthcare of chronic patients, all data collected until 12/31/2021 underwent an in-depth double-blinded quality control. This control was aimed to make the Pdta Net database as representative as possible of the existing documents closest to a real CP. RESULTS: From 2005 to 2021, 729 regional CPs have been approved: 404 on high-impact chronic diseases and 220 on rare conditions. The CPs of chronic diseases, mostly edited by Piemonte (45 CPs), Campania (34) and Toscana (33) Regions, mainly concern on diabetes (19), chronic obstructive pulmonary disease (15), heart failure (13), stroke, multiple sclerosis and colorectal neoplasms (12 each one), breast cancer (11), dementia and chronic kidney disease (10 each one). Most of the CPs on rare diseases have been edited by Regions with an established Rare Disease Network, i.e., Lombardia (125 CPs), Lazio (74) and Toscana (40): neurology (61) and oncology (52) were the most represented clinical areas. CONCLUSIONS: The high number of CPs approved in Italy confirms an increasing interest of the healthcare institutions. The collected CPs show an extreme variety of titles, text structures and disease choices. Given the absence of an institutional observatory and of devotees of shared and harmonized CPs, annually Pdta Net makes available an updated and complete overview of these governance tools, which are essential for the upcoming changes of the Italian national health service.

[Mutational oncology of lung cancer: molecular markers, drugs, negotiation conditions and experiences in national reference centers.] / L'oncologia mutazionale del carcinoma polmonare: marcatori molecolari, farmaci, condizioni negoziali ed esperienze in centri di riferimento nazionale.

The gradual availability of genomic profiling tests and the "agnostic approvals" from FDA and EMA have opened the oncology mutational model phase, which complements and integrates the traditional hystological approach. The non-small-cell lung cancer (NSCLC) is characterized by many molecular alterations and represents the need of a change from the traditional diagnostic, therapeutic and organisational paradigms to the "mutational" ones. From the Italian National Healthcare System point of view, access and reimbursement of drugs based on the hystological model were managed thorugh the Italian Medicines Agency's (AIFA) monitoring registries and the managed entry agreements: risk-sharing, cost-sharing and payment by results. The Italian reference oncological centres, which contributed to this report with their experiences, have shown the heterogenous approach to the molecular diagnostics (included next generation system tests). Facing the high complexity of the mutational model, outcomes handling and genomic profiling tests access inevitably result different among centres. The activation of multidisciplinary groups for the government of clinical processes, appropriateness and economic sustainability are essential. The Molecular Tumor Board (MTB) allows the management of such complexity, the interpretation of genomic profiling outcomes and the choice of drugs that are alrealdy authorized by AIFA, off-label or still under investigation. Moreover, in order to guarantee the uniformity, the data traceability and the transparency of assessment reports, a network of MTB must be validated by AIFA through specific criteria. To date, the oncological centres presented by this report are undergoing the experimental phase of the national genomic operating system implementation and represent the starting point of the deep organisational changement to the mutational approach and of its real and appropriate integration into the daily clinical practice.

Real-world Prescription Pattern, Discontinuation and Costs of Ibrutinib-Naïve Patients with Chronic Lymphocytic Leukemia: An Italian Healthcare Administrative Database Analysis.

BACKGROUND AND OBJECTIVE: In order to integrate the existing and inconsistent information from clinical trials and real-world practice on chronic lymphocytic leukemia (CLL) treated with ibrutinib, this analysis aimed to describe the prescription pattern of new users of ibrutinib affected by CLL, focusing on discontinuation, severe adverse events (AEs) and change of treatment, and to assess the integrated healthcare expenditure from the Italian National Health System (INHS) perspective. METHODS: Starting from the ReS database, adults with at least a supply of ibrutinib (ATC code L01XE27) were selected from 01/01/2016 to 12/31/2017. Those without any ibrutinib supply in the year before the index prescription were considered new users. Out of them, only patients with at least a primary or secondary in-hospital diagnosis of CLL (ICD-9-CM code 204.1*) from 01/01/2013 to 12/31/2018 were further broken down according to the ibrutinib's line treatment (first line-FL; second or later line-SLL) and analysed. They were characterized by sex and age in the selection period. Mean annual consumption (defined daily doses [DDD]), treatment discontinuation, changes of therapy, interruptions and healthcare costs in charge of the INHS were assessed during two follow-up years. RESULTS: Out of more than 5 million inhabitants of the ReS database, 69 new ibrutinib users and diagnosed with CLL in 2016 (incidence: 1.6 × 100,000) and 41 in 2017 (incidence: 0.9 × 100,000) were selected. Of these, 21 (19.1%) were FL ibrutinib users and 89 (80.9%) were SLL ones, mostly males and with mean ages (±SD) of 65 ± 14 and 70 ± 10, respectively. The mean annual consumption among FL users decreased from 222.2 DDD per patient treated to 216.0 DDD, while increased among SLL patients from 238.6 DDD to 260.1 DDD, in the first and second follow-up year, respectively. The discontinuation rate was about 40% in the first year, similarly among FL and SLL users. SLL patients discontinued more frequently (52.8% vs 20.0%) in the second year. Very few AEs were recorded. The 62.5% of FL and 55.6% of SLL users discontinuing ibrutinib in 1-year follow-up, while one SLL patient (5.3%) in the second year changed therapy. The 20.0% and 15.9% of all new users in first and second year interrupted ibrutinib. The total integrated cost of FL patients was €55,732 reducing by about €15,000, while it was €58,716 for SLL ones decreasing by €6,000, respectively, in the first and in the second year. Pharmaceuticals were the key cost driver (ibrutinib accounted for more than 77%). CONCLUSIONS: This analysis on Italian administrative data provided results about prescription patterns of ibrutinib FL and SLL new users with CLL, focusing on discontinuation, treatment change and healthcare costs over 2-year follow-up, and contributed to improve the knowledge on this hard-to-treat disease.

[Real-world analysis of obstructive respiratory tract disorders: characterization, health care and costs.] / Analisi real-world dei disturbi ostruttivi delle vie respiratorie: caratterizzazione, assistenza sanitaria e costi.

INTRODUCTION: This analysis has described the burden of patients with asthma, chronic obstructive pulmonary disease (COPD), asthma/COPD mixed conditions or undefined obstructive diseases (UODs), from the Italian National Health System point of view. METHODS: In the accrual period (2015), starting from the ReS database, a record linkage among demographic, pharmaceuticals, hospitalizations and outpatient specialist services databases has identified patients affected by only asthma, only COPD, asthma/COPD and UODs. From the less recent date of identification, each patient was analyzed in one previous year and in two years of follow-up (at most up to 12/31/2017). In the accrual period, in the previous one and in 2-year follow-up sinus polyps was researched. One-year free filled respiratory (ATC code R03) and concomitant prescriptions, outpatient specialist services, hospitalizations were described. Two-year costs were assessed annually. RESULTS: In 2015, 110,453 subjects with asthma (16.6 x1000 ≥12 years old), 229,747 with COPD, 8828 with asthma/COPD (55.5 x1000 and 2.1 x1000 ≥40 years, respectively) and 75,072 with UODs (27.2 x1000 subjects aged 40 to 65) were selected. Sinus polyps was found in 753 patients with asthma, 181 with COPD and 122 with asthma/COPD. A very high use of inhaled corticosteroids - ICS (R03AB) as monotherapy and as fixed association ICS/LABA and of cardiovascular drugs was highlighted among patients with COPD and asthma/COPD. The spirometry test was used in 21.4% patients with asthma/COPD, in 9.2% with asthma, in 8.6% with COPD and in 5.8% with UODs. Subjects with COPD and asthma/COPD were the most frequently hospitalized, mainly due to respiratory and cardiovascular causes, and those with the longest in-hospital stay. On average, the mean overall one-year expenditure per COPD or asthma/COPD patient was three times higher than per asthma or UOD one (€3508/€3613 vs €942/€1394, respectively). CONCLUSIONS: Concomitant drugs and hospitalizations due to other causes than respiratory ones accounted for the highest expenses. In general, comorbidities and cardiopulmonary complications played a key role in obstructive airway disease managing and controlling, by determining unsustainable socio-economic impacts.

HR+/HER2- Metastatic Breast Cancer: Epidemiology, Prescription Patterns, Healthcare Resource Utilisation and Costs from a Large Italian Real-World Database.

BACKGROUND AND OBJECTIVE: Breast cancer is the second leading cause of cancer death worldwide. The economic burden of breast cancer is crucial for the sustainability of healthcare systems. The objective of this study was to estimate the burden of HR+/HER2- metastatic breast cancer (MBC) in Italy, in terms of incidence, prescription patterns, healthcare resource utilisation and costs for the National Health System (NHS). METHODS: A cohort study based on healthcare administrative data (ReS database), covering > 10 million Italians, was performed. Incident cases of HR+/HER2- MBC were identified among adult women in 2013. The cohort was followed-up for 2 years to describe healthcare utilisation and integrated costs (pharmaceuticals, hospitalisations and outpatient services) for NHS. Prescription patterns were described as first-line choice and therapeutic changes. Specific therapeutic changes were used as proxies of disease progression. A survival analysis was performed to estimate the time from diagnosis to first disease progression. RESULTS: Of 5174,723 women, 355 cases of de novo HR+/HER2- MBC were selected (incidence: 6.9 per 100,000). During the 1st follow-up year, they generated an average cost of €7543, whereas €4834 in the 2nd year. The 85.9% received a monotherapy, while the 14.1% received a combination therapy. The most used monotherapy was nonsteroidal-aromatase-inhibitors (45.9%), while the most prescribed combination was tamoxifen + luteinizing hormone releasing hormone (LHRH) analogues (6.2%). Therapeutic changes occurred in 45.4% of patients, especially from chemotherapy to nonsteroidal-aromatase-inhibitors, after an average of 276.8 days from the first treatment. Disease progression was identified in 22.5% of patients occurring after a mean 13 ± 6 months from diagnosis. CONCLUSIONS: This detailed picture of HR+/HER2- MBC, based on real-world data, could be helpful in health technology assessment and expenditure forecasts of future therapeutic strategies for this condition in Italy.

[Facts and figures of clinical pathways in Italy: results from the PDTA Net project.] / I numeri dei percorsi diagnostico-terapeutici assistenziali (PDTA) in Italia: risultati dal progetto PDTA Net.

The approval of clinical pathways (CPWs) represents a key step to focus the care management on the patient. The PDTA Net project, by ReS Foundation and CINECA, aims to create a reference tool to study how the local organizational models influence healthcare and clinical outcomes. The article shows the analysis of all CPWs approved by Italian Regions and Autonomous Provinces until 31/12/2018. The search for documents was performed on the institutional websites through specific keywords. CPWs were filled into a database, according to the Region, publication year, disease of interest (distinguishing between chronic diseases with high epidemiological impact and rare diseases) and relevant clinical area. All documents were analyzed by geographical and temporal distribution, the latter also according to ministerial measures. From 2005 to 2018, 536 Regional CPWs were approved (316 for chronic diseases with a high epidemiological impact and 220 for rare diseases). The Regions with the highest number of CPWs of chronic diseases were Umbria (34 CPWs) and Piemonte (33). The most addressed clinical areas were: oncology (72), neurology (60), cardiology (34) and metabolic disorders (22). The most issued diseases were: diabetes (17), trauma/polytrauma (15), chronic obstructive pulmonary disease and multiple sclerosis (12 each), stroke (11), rheumatoid arthritis, breast cancer and colorectal neoplasms (10 each). The publication of the documents was affected by ministerial measures (Balduzzi Law, National Chronicity Plan, Diabetic Disease Plan and National Dementia Plan). The majority of CPWs on rare diseases was retrieved in Regions with activated Rare Disease Networks: Lombardia (110 CPWs), Lazio (64) and Toscana (17). This study showed that, to date, in Italy there are several CPWs published at Regional level, nevertheless their structure and application are heterogeneous and strongly influenced by the National Plans. All analyzed documents are available through the web platform of the project https://fondazioneres.it/pdta/. This project could be useful for health system stakeholders, in order to encourage the transition to new health governance and making CPWs effective governance tools.

The use of antiplatelet agents after an acute coronary syndrome in a large community Italian setting of more than 12 million subjects.

BACKGROUND: Antiplatelet agents are the cornerstone of medical treatment in acute coronary syndromes. The aim of this study was to evaluate the clinical epidemiology of patients after an acute coronary syndrome treated with different antiplatelet agent regimens in a large real community setting. METHODS: The ARCO database, including more than 12 million inhabitants, was evaluated. Antiplatelet agent prescriptions were analysed as follows: aspirin, clopidogrel, other antiplatelet agents used alone; the free and fixed combination of clopidogrel and aspirin; the free combination of aspirin with other antiplatelet agents. Healthcare costs included drug prescriptions (prices reimbursed by the Italian National Health System), outpatient specialist services and hospitalisations (Italian national tariffs). RESULTS: From 1 January to 31 December 2014, 26,834 patients were discharged after an acute coronary syndrome. Of these, 19,333 (77%) were prescribed with an antiplatelet agent. Among patients undergoing a revascularisation procedure either percutaneous or surgical (47% of the total population), antiplatelet agents were prescribed in 90% of cases. Dual antiplatelet agent therapy was prescribed in 49.6% of the total population and in 68.5% of those treated invasively. Prescription continuity was observed in just 75% of patients. The highest adherence was observed for the fixed combination of aspirin/clopidogrel (81.5%). Throughout one year of follow-up re-hospitalisation occurred in 47.9% of the patients and the direct cost per patient treated with an antiplatelet agent was €13,297 versus €16,647 in patients not treated with antiplatelet agents. CONCLUSIONS: This study highlights that antiplatelet agent prescriptions, specifically dual antiplatelet agent therapy, are at least suboptimal as well as in prescription continuity. Hospitalisations were frequent and were the main driver of the costs, accounting for 84% of the total costs for the Italian National Health System.

Target Population of Non-deferrable Surgery and Uncontrolled Severe Bleeding Related to Dabigatran.

PURPOSE: This observational study was aimed to identify patients who experienced non-deferrable surgery and/or uncontrolled severe bleeding following dabigatran administration and then are potentially eligible to the use of the specific antidote idarucizumab in a real-world setting. METHODS: From the big Italian real-world database ARCO, a cohort of adult patients treated with dabigatran and hospitalized due to diagnoses attributable to urgent interventions and/or major bleeding was selected in 2014. Baseline characteristics and all-cause hospitalizations, specialist/diagnostic outpatient services, and healthcare costs over the 1-year follow-up were described. RESULTS: Out of 16,756,843 Italian citizens, 271,540 (1.9%) were prescribed with oral anticoagulants, and specifically, 17,450 with dabigatran. Patients identified to be hospitalized for non-deferrable surgery (n = 106) and/or uncontrolled severe bleeding (n = 190) following dabigatran use were 289 (1.7%) [mean age (± SD) 79 ± 7, 50% of female sex]. On average, patients stayed in hospital 13.7 and 17.0 days, respectively. The per patient and per year cost to the Italian National Health System was on average 19,708€ (specifically 1487€ for drugs, of which 311€ for dabigatran, 17,353€ for all-cause hospitalizations, and 869€ for outpatient care), about four times more than the mean healthcare integrated cost of a single patient treated with dabigatran (4775€). CONCLUSIONS: This analysis of the ARCO database reliably describes the population potentially eligible to the dabigatran reversal agent, idarucizumab. These data may be useful for Healthcare Decision Makers to organize, define, and improve present and future emergency healthcare, mainly as starting point for cost-effectiveness analyses of new reversal agents.

Insuficiencia cardíaca en el mundo real. Un punto de vista italiano / Real world evidence of heart failure: an Italian point of view

Objetivos: las características de la población de pacientes con insuficiencia cardíaca (IC) en los estudios clínicos aleatorizados (ECA) son, generalmente, muy distintas a las de la práctica real debido a criterios específicos de elegibilidad. Estos pacientes no representan totalmente "el mundo real" de esta condición clínica. El análisis de una base de datos administrativa puede ser útil para describir mejor las características de los pacientes con IC en el mundo real. Métodos: los datos provienen del observatorio italiano ARNO, que incluye una población de aproximadamente 2.500.000 de personas registradas en el Servicio Sanitario Nacional Italiano (SSNI). Fueron seleccionados los egresos por IC (1 de enero de 2008 al 31 diciembre de 2012). Describimos las características clínicas, los tratamientos, la tasa y causas de rehospitalizaciones y los costos directos para el SSNI ocasionados durante un año de seguimiento. Resultados: de los 2.456.739 individuos incluidos en la base de datos, 54.059 (2,2%) fueron hospitalizados por IC, 41.413 fueron dados de alta con vida con un tratamiento prescripto para su IC. La edad media fue de 78±11 años, las mujeres fueron el 51,4%. Solo 26,6% fue manejado en un ámbito cardiológico. Las comorbilidades más frecuentes fueron diabetes (30,7%), enfermedad pulmonar obstructiva crónica (EPOC) (30,5%) y depresión (21%). Inhibidores de la enzima convertidora de angiotensina y antagonistas de receptores de angiotensina (IECA/ARAII), betabloqueantes (BB) y antagonistas de receptor de mineralocorticoides (ARM) fueron prescriptos en 65,8%, 49,7% y 42,1% respectivamente. Al menos una rehospitalización ocurrió en 56,6% de los pacientes en un año de seguimiento, el 49% de ellas fueron por causas no cardiovasculares. El costo directo por paciente fue de 11.867 euros por año, debido fundamentalmente a la hospitalización. Conclusiones: la evidencia del mundo real provee una descripción de las características de los pacientes y los patrones de tratamiento que son muy diferentes de aquellos reportados en los ECA. Los costos del SNISS son ocasionados principalmente por las hospitalizaciones, las cuales frecuentemente se deben a causas no cardiovasculares.

Aims: the population of patients with heart failure (HF) randomized in clinical trials is generally far from real practice because selected according to specific eligibility criteria. These patients do not fully represent the "real world" of this clinical condition. Analysis of an administrative database can be useful to better describe the characteristics of real world patients with HF. Methods: data came from the Italian ARNO Observatory including a population of nearly 2,500,000 inhabitants of the Italian National Health Service (INHS). Patients were selected when discharged for HF (January 1, 2008 - December 31, 2012). We described the clinical characteristics the pharmacological treatments, rate and type of re-hospitalizations and direct costs for the INHS occurring during 1 year follow-up (FU). Results: of the 2,456,739 subjects included in the database, 54,059 (2.2%) were hospitalized for HF: 41,413 were discharged alive and prescribed on HF treatments. Mean age was 78±11 years, females accounted for 51.4%. Just 26.6% were managed in a cardiology setting. The more frequent co-morbidities were diabetes (30.7%), COPD (30.5%) and depression (21%). ACE-inhibitors/Angiotensin Receptor Blockers, Betablockers and Aldosterone antagonists were prescribed in 65.8, 49.7 and 42.1% of patients. At least one re-hospitalization occurred during the 1-year follow-up in 56.6% of patients, 49% of them were due to non-cardiovascular causes. INHS's direct cost per patient per year was 11,867€ mainly driven by hospitalizations. Conclusions: real world evidence provides a description of patients' characteristics and treatment patterns that are very different from those reported by randomized clinical trials. Costs for the INHS are mainly driven by hospitalizations which are often due to non-cardiovascular reasons.
