Healthcare Systems and Artificial Intelligence: Focus on Challenges and the International Regulatory Framework.

BACKGROUND: Nowadays, healthcare systems are coping with the challenge of countering the exponential growth of healthcare costs worldwide, to support sustainability and to guarantee access to treatment for all patients. METHODS: Artificial Intelligence (AI) is the technology able to perform human cognitive functions through the creation of algorithms. The value of AI in healthcare and its ability to address healthcare delivery issues has been a subject of discussion within the scientific community for several years. RESULTS: The aim of this work is to provide an overview of the primary uses of AI in the healthcare system, to discuss its desirable future uses while shedding light on the major issues related to implications within international regulatory processes. In this manuscript, it will be described the main applications of AI in various aspects of health care, from clinical studies to ethical implications, focusing on the international regulatory framework in countries in which AI is used, to discuss and compare strengthens and weaknesses. CONCLUSIONS: The challenges in regulatory processes to facilitate the integration of AI in healthcare are significant. However, overcoming them is essential to ensure that AI-based technologies are adopted safely and effectively.

Sex affects immune response capacity against COVID-19 infection.

The genetic variability of each individual may lead to the identification of completely different genetic polymorphisms which are associated with a different sensitivity to infectious diseases in humans. Such genetic variability allows the immune system to respond differently to viral agents, therefore only a fraction of humans develop severe symptoms, as happened with SARS-CoV-2. Such knowledge is critical to enable the development of appropriate pharmacological solutions to prevent the consequences of insufficient immunity in dealing with serious viral diseases such as SARS-CoV-2. For instance, global epidemiological data show that male sex is a risk factor for the severe evolution of SARS-CoV-2 disease. Men, due to higher production of Testosterone (TLT), are more vulnerable than females. Women, due to greater expression of the TLR7 gene found on the X chromosome, a key innate immunity gene that encodes Toll-like proteins, are able to synthesise more antiviral proteins and interferons in dendritic cells, resulting in a more robust immune system capable of preventing severe SARS-CoV-2 viral disease. This manuscript highlights how human genetic variability can lead to severe infectious symptoms in some individuals who must take appropriate prophylactic actions, such as vaccination, to prevent this.

Atopic dermatitis: treatment and innovations in immunotherapy.

Atopic dermatitis (AD) is a common inflammatory skin disease characterized by itching and skin barrier dysfunction. Moderate to severe AD is often refractory to first-line topical treatments, and systemic immunosuppressants have been shown to be effective but have significant adverse effects. The paucity of basic treatments has contributed to the development of targeted topical and systemic immunotherapies based on the use of small molecules and biologic drugs which can directly interact with AD pathogenetic pathways. They represent a new era of therapeutic innovation. Additional new treatments are desirable since AD is a heterogeneous disease marked by different immunological phenotypes. This manuscript will review the mechanism of action, safety profile, and efficacy of promising new systemic immunological treatments for AD. Since moderate to severe AD can result in poor quality of life, the development of targeted and well-tolerated immunomodulators is a crucial purpose. The introduction of new pharmacological agents may offer new therapeutic options. However, there is the need to evaluate how "narrow-acting" agents, such as individual interleukin inhibitors, will perform under the safety and efficacy profiles compared with "broad-acting" agents, such as JAK inhibitors.

Antibacterial agents and the fight against antibiotic resistance: A real-world evidence analysis of consumption and spending by an Italian healthcare company.

INTRODUCTION: The escalating bacterial resistance stands as an increasingly pertinent concern, particularly in the post-pandemic era where the use of antibiotics appears to be relentlessly surging, giving rise to profound apprehensions. The substantial utilization of last-generation penicillins and cephalosporins is anticipated to imminently result in the emergence of superbugs for which therapeutic solutions will be scarce. METHODS: An analysis of antibiotic consumption in the hospital setting has been conducted in an Italian healthcare organization. Querying the internal management system facilitated the calculation of indicators and assessment of prescription trends. RESULTS: A comparison has been made between the first half of 2023 and the first half of 2022, to highlight the exponential growth in the consumption of beta-lactam antibiotics, with consumption doubling compared to the previous year's semester. Overall, considering the prescription averages, there is a prescribing growth of +29% concerning hospitalization and +28% concerning hospital discharge. However, it should be noted that the consumption of certain antibiotics such as sulphonamides and trimethoprim (-103.00%), tetracyclines (-54.00%), macrolides, lincosamides and streptogramins (-50.00%) and colistin (-13.00%) decreased. CONCLUSION: This real-world evidence analysis aimed to support the justified and comprehensible global concerns regarding bacterial resistance. The extensive consumption of antibiotics will inevitably lead to the development of increasingly drug-resistant bacteria for which no antibiotic may be efficacious. National programs addressing antibiotic resistance and the awareness of all healthcare personnel must be accorded the utmost priority to enhance consumption data and, consequently, safeguard future human survival.

Covid-19 psychological distress: Analysis of antipsychotic drugs' use in an Italian population sample.

BACKGROUND: The current pandemic, in addition to putting a strain on healthcare systems and global economies, has exacerbated psychiatric problems and undermined the mental health of many individuals. In an Italian cohort, this phenomenon has been assessed through a retrospective study aimed at evaluating the consumption and costs of antipsychotic drugs between 2020 and 2022. METHODS: All dispensations made in local pharmacies accessible to the public have been extracted from a database called 'Sistema Tessera Sanitaria', which covers a population of approximately one million people residents in the ASL Napoli 3 Sud. Consumption data expressed in defined daily dose (DDD) and expenditure data expressed in Euro have been extrapolated. RESULTS: The results in the years 2020-2021 were relatively consistent, with consumption and expenditure decreasing slightly from 2020 to 2021. In 2022, the results showed a decrease in consumption and expenditure (2,706,951.07 DDD and €1,700,897.47) representing the reduced accessibility of patients to the healthcare facilities due to the pandemic. However, it should be noted that the antipsychotic drug aripiprazole showed an upward trend, registering an increase in consumption. CONCLUSION: Despite expectations of increased consumption of antipsychotic medications, real-world evidence indicated a different phenomenon, with the pandemic seemingly not affecting the consumption of these drugs. The difficulty in accessing care and medical appointments has probably influenced this data, masking the therapeutic needs of citizens. It will be necessary to assess in the coming years, as normal clinical activity resumes, whether there will be a growing consumption of these medications, which represent one of the main expenditure categories for the National Healthcare System.

Anti-CGRP mAbs for the Preventive Treatment of Migraine: An Overview Review and a Cost Saving Analysis in the Global Scenario.

Objectives: Migraine is a neurological disease with a high frequency of incidence. The new monoclonal antibodies selective for the calcitonin gene-related peptide and its ligand (anti-CGRP mAbs) have been marketed both in the USA and EU based on the positive efficacy results in the prevention of migraine. This search has been carried out with the aim of collecting real-world evidence on the effectiveness of anti-CGRP mAbs, performing a cost-savings analysis, and comparing performances among anti-CGRP mAbs medicines marketed in the American and European market. Methods: The literature review has been performed in PubMed database on 31 December 2022; the cost of the unitary dose of anti-CGRP mAbs has been extracted consulting an American national database. Results: The results confirm efficacy and good tolerability of anti-CGRP mAbs, determining a difference in the purchase price. In fact, all extracted studies showed a protective risk factor exposure in monthly migraine days reduction for all the anti-CGRP mAbs, whereas the cost analysis showed that using eptinezumab, in a quarter there is a cost saving of at least $425 per patient, compared with the other anti-CGRP mAbs. Conclusions: With equal efficacy and equal safety, anti-CGRP mAbs should be prescribed also regard to the cost established at the negotiation, making sure to guarantee the best treatment to the patients, but at the same time impacting as little as possible to the healthcare services resources.

What Do We Know About the Smallpox Virus? A Journey Between Clinic and Therapy.

PURPOSE: Modern research is increasingly focusing on the study of new viruses and the re-emergence of past microbes, such as Coronaviruses, particularly Sars-Cov2 that was responsible for the very recent pandemic. METHODS AND RESULTS: This infection manifested itself and still continues to manifest as a severe respiratory syndrome. The main discriminator of whether or not one succeeds in overcoming this infection may depend on a great many factors, but the main one is definitely determined by vaccination, which has minimized hospitalizations and more severe syndromes. CONCLUSION: Recently, a new virus, the monkeypox virus, which was previously confined to Central and West Africa but is now gradually spreading to more than 30 countries including the United States of America, where such an infection is not endemic, is coming forward again.

Omicron variant evolution on vaccines and monoclonal antibodies.

The severe acute respiratory syndrome coronavirus (SARS-CoV)-2 responsible for the global COVID-19 pandemic has caused almost 760 million confirmed cases and 7 million deaths worldwide, as of end-February 2023. Since the beginning of the first COVID-19 case, several virus variants have emerged: Alpha (B1.1.7), Beta (B135.1), Gamma (P.1), Delta (B.1.617.2) and then Omicron (B.1.1.529) and its sublineages. All variants have diversified in transmissibility, virulence, and pathogenicity. All the newly emerging SARS-CoV-2 variants appear to contain some similar mutations associated with greater "evasiveness" of the virus to immune defences. From early 2022 onward, several Omicron subvariants named BA.1, BA.2, BA.3, BA.4, and BA.5, with comparable mutation forms, have followed. After the wave of contagions caused by Omicron BA.5, a new Indian variant named Centaurus BA.2.75 and its new subvariant BA.2.75.2, a second-generation evolution of the Omicron variant BA.2, have recently been identified. From early evidence, it appears that this new variant has higher affinity for the cell entry receptor ACE-2, making it potentially able to spread very fast. According to the latest studies, the BA.2.75.2 variant may be able to evade more antibodies in the bloodstream generated by vaccination or previous infection, and it may be more resistant to antiviral and monoclonal antibody drug treatments. In this manuscript, the authors highlight and describe the latest evidences and critical issues have emerged on the new SARS-CoV-2 variants.

Pharmacological Agents with Antiviral Activity against Monkeypox Infection.

Monkeypox infection is caused by a virus of the genus Orthopoxvirus, a member of the Poxviridae family. Monkeypox virus is transmitted from individual to individual through contact with lesions, body fluids, and respiratory droplets. The infection caused by monkeypox is usually a self-limited disease with mild symptoms lasting 2 to 4 weeks. Monkeypox typically presents with fever, rash, and enlarged lymph nodes. New vaccines have recently been authorized for the prevention of monkeypox infection, whereas there are no specific pharmacological antiviral treatments for monkeypox infection. However, because the viruses which cause adult smallpox and monkeypox are similar, antiviral drugs developed in the past have also shown efficacy against monkeypox. In this review, we highlight the in vitro and clinical evidence found in the literature on the efficacy and safety of pharmacological agents with antiviral activity against monkeypox infection and the different regulatory aspects of countries.

Recovery of suspended reimbursements of high-cost drugs subjected to monitoring registries and negotiated agreements (MEAs): a tool for governance and clinical appropriateness in the Italian reality.

The Monitoring Registries and negotiated agreements (MEAs) established by the Italian Medicines Agency (AIFA) exemplify a pinnacle of excellence in Italian healthcare governance, playing a pivotal role in achieving economic sustainability and ensuring judicious allocation of financial resources. Within a local territorial health company catering to a populace of around 1 million individuals in Italy, an assessment of the meticulous implementation of all negotiation procedures was carried out by scrutinizing the monitoring records. This examination served to pinpoint and address potential issues in the platform management executed by healthcare professionals, including physicians and pharmacists. Such issues had the potential to result in economic setbacks owing to the non-reimbursement from pharmaceutical companies. Through diligent verification undertaken by the pharmacists, a financial recovery amounting to approximately €579,443.4 for the fiscal year 2022 was achieved. The essence of this analysis is to underscore how collaborative, multidisciplinary efforts between physicians and pharmacists yield tangible economic advantages. This collaborative approach ensures a streamlined healthcare system characterized by efficiency, devoid of unnecessary expenditures, and marked by the highest standards of care appropriateness, ultimately serving the best interests of the citizens.

The use of the biosimilar drug can lead to large health care savings that can be reinvested for continued innovation: Analysis of consumption of an Italian health care company.

BACKGROUND: Biosimilar drugs offer an opportunity for all global healthcare systems because they provide significant cost savings while ensuring equal efficacy and safety in the treatment of chronic diseases. These savings can be allocated to support ongoing innovation. METHODS: An analysis of the usage of major biosimilar drugs across various therapeutic areas has been conducted within an Italian healthcare company serving a population of over one million. Data on consumption, expenditure, and the number of treated patients has been extracted from the company's databases. Finally, a comparison with the year 2021 has been performed to determine if biosimilar drug usage increased in 2022. RESULTS: In 2022, the data reveals that a substantial portion of the analysed active ingredients are being used as biosimilar drugs, except in a few residual cases. However, among the most consumed drugs, resistance still exists in the case of Adalimumab and Etanercept, for which expenditure on originator drugs exceeds 2 million euros. CONCLUSION: The 2022-2021 comparison highlights the increasing use of biosimilar drugs. This data is encouraging and suggests that in the coming months, we may achieve total utilization, which would be to the benefit of the National Health System (NHS) and the citizens who can rely on an efficient and sustainable healthcare policy that is continually improving.

Trend analysis of proton pump inhibitor consumption and expenditure: The real-world evidence.

INTRODUCTION: Proton pump inhibitors (PPIs) constitute a widely utilized pharmaceutical class, frequently associated with notable instances of therapeutic inappropriateness. Such patterns of misuse not only contribute to elevated healthcare expenditure, but may also exacerbate clinical conditions in certain patients. METHODS: A comprehensive analysis was conducted between 2019 and 2023 to assess all prescriptions dispensed using the Anatomical, Therapeutic and Chemical (ATC) classification system, which allowed trends among primary PPIs to be visualized. This was achieved by calculating the defined daily dose (DDD) and then defining the total expenditure incurred on these drugs. RESULTS: With regard to the prescription of PPIs, an upward trend in consumption was observed with a decreasing expenditure, due to the phenomena of drug generics and increased competition between pharmaceutical companies, ranging from €9,512,481.22 in the first six months of 2019 to €8,509,820.80 in the first six months of 2023. From 2019 to 2023, consumption increased by approximately 3 million DDDs for a total ranging from 18,483,167.59 DDDs to 21,480,871.00 DDDs. Pantoprazole and esomeprazole, the most expensive drugs compared to omeprazole, rabeprazole and lansoprazole, accounted for 61.4% of therapies in the first six months of 2023, up from 2019, where these two drugs were prescribed 54.9%. CONCLUSION: Within this analysis, we provide an illustrative representation of the prescribing trends for PPIs within a European context. Omeprazole, rabeprazole and lansoprazole appear to be the cheapest drugs compared to pantoprazole and esomeprazole. However, the results show that the most widely used PPIs, despite their therapeutic equivalence, are precisely the high-cost ones, thus generating higher expenditure for central governments.

The Impact of Antimicrobial Resistance in Cystic Fibrosis.

The phenomenon of antimicrobial resistance (AMR) is a critical global health challenge, with prospects indicating its potential to become the leading cause of death worldwide in the coming years. Individuals with pre-existing conditions, such as neoplastic disease undergoing chemotherapy, those on immunosuppressive therapy, and individuals with rare diseases like cystic fibrosis (CF), face heightened challenges due to AMR. CF is a rare disease caused by a deficiency in the synthesis of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) channel protein, resulting in multi-organ clinical symptoms, particularly in the respiratory system. PwCF experience recurrent pulmonary exacerbations triggered by bacterial or viral infections, making them particularly vulnerable to the impact of AMR. This review delves into the complex relationship between AMR and climate dynamics, focusing on the unique challenges faced by individuals with CF. It discusses the methods employed to measure AMR, its global impact on antibiotic resistance, and the specific microbial communities present in the CF airway. The review also explores the intricacies of antimicrobial resistance within the context of cystic fibrosis, emphasizing the urgent need for research in this field.

Comparison and Analysis of Antibiotic Consumption in Two Italian Hospital Settings in Relation to the Fight of Antimicrobial Resistance.

Introduction: The emergence and spread of drug-resistant pathogens due to the improper use of antibiotics have become increasingly apparent in recent years. Objective: This retrospective comparative analysis aimed to assess and compare antibiotic prescription trends in Italy across two different regions based on geographic area and healthcare structure. One region represents a large hospital institution, while the other represents a populous local Italian health agency. The study also examined the impact of documented antibiotic stewardship programs and efforts to promote responsible antibiotic use at all levels, in alignment with international goals. Antibiotic consumption data were collected from the Umberto I Polyclinic Hospital and the ASL Napoli 3 South Local Health Agency. Methods: To compare consumption between regions, a standardized comparison using the Defined Daily Dose (DDD) was employed. The internal management system of each healthcare facility records all prescriptions and drug dispensations, and these data were extrapolated for this retrospective study. Results: A comparative assessment between the first half of 2022 and 2023 (January-June) highlighted a significant increase in beta-lactam antibiotic consumption, showing a twofold rise compared to the previous year's term. Regarding prescription averages, there was a noticeable increase of +29.00% in hospitalizations and +28.00% in hospital discharges within the ASL Napoli 3 South. Conversely, at Policlinico Umberto I, there was a marginal increase of +1.60% in hospitalizations and a decrease of -7.40% in hospital discharges. Conclusions: The study offers valuable insights into expenditure patterns and antibiotic consumption, underscoring the need for enhanced prescribing practices and awareness campaigns to address the issue of antibiotic resistance. The findings stress the importance of implementing international guidelines to combat the growing threat of antibiotic resistance and ensure the effective management of infectious diseases.

Real-World Effectiveness of Calcitonin Gene-Related Peptide-Binding Monoclonal Antibodies for Migraine Prevention: A Systematic Review.

Background: Migraine is a neurological disease with a high incidence. The new anti-calcitonin gene-related peptide monoclonal antibodies (anti-CGRP mAbs) have demonstrated effectiveness in preventing episodic and chronic migraine. Objective: To collect evidence of the real-world effectiveness of anti-CGRP mAbs by assessing outcomes such as reduction in monthly migraine days (MMDs), reduction in monthly headache days (MHDs), and percentage of patients having a 50% reduction in MMDs. Data Sources: The PubMed database was searched for the period from inception to October 20, 2021. Study Selection and Data Extraction: Of interest for this review were studies that evaluated the real-world effectiveness of anti-CGRP mAbs in terms of MMDs and reduction in MHDs. The search terms included "migraine", "monthly migraine days", and various drug names. The data are reported in terms of patients' baseline characteristics and treatment effectiveness. Data Synthesis: A total of 46 studies were evaluated, of which 30 (enrolling a total of 4273 patients across 10 countries) were included in the systematic review. The greatest absolute reduction in MMD was from 20.4 at baseline to 10.7 after 3 months of treatment. After 6 months, the greatest absolute difference was 10, relative to baseline. The largest absolute reduction in MHD at 3 months was from 22 to 8, whereas at 6 months, the greatest absolute reduction in MHD was 13. The treatment could be considered clinically effective (≥ 50% reduction in MMDs) for 41% of patients at 3 months and about 44% of patients at 6 months. Conclusions: Despite substantial variability in baseline values, this review confirmed the effectiveness of anti-CGRP mAbs, which yielded important clinical reductions in both MMDs and MHDs.

Contexte: La migraine est une maladie neurologique à incidence élevée. Le nouvel anticorps monoclonal qui se lie au peptide lié au gène de la calcitonine (AcM anti-CGRP) a démontré son efficacité pour prévenir les migraines épisodiques et chroniques. Objectif: Recueillir des éléments probants concernant l'efficacité réelle des AcM anti-CGRP en évaluant des résultats comme la réduction du nombre de jours de migraine par mois (JMM), la réduction du nombre de jours de céphalées par mois (JCM) ainsi que le pourcentage de patients ayant une réduction de 50 % du nombre de JMM. Sources des données: La base de données PubMed a été utilisée pour mener une recherche pour la période allant du début jusqu'au 20 octobre 2021. Sélection des études et extraction des données: Les auteurs de la revue se sont intéressés aux études qui avaient évalué l'efficacité réelle des AcM anti-CGRP en termes de réduction du nombre de JMM et du nombre de JCM. Les termes de recherche comprenaient « migraine ¼, « jours de migraine par mois ¼ et divers noms de médicaments. Les données sont rapportées en termes de caractéristiques de base des patients et d'efficacité du traitement. Synthèse des données: Au total, 30 des 46 études répondant aux critères d'inclusion (comprenant un total de 4273 patients dans 10 pays) ont été retenues pour la revue systématique. La réduction absolue de JJM la plus importante était de 20,4 (la base de référence) à 10,7 après 3 mois de traitement. Après 6 mois, la différence absolue la plus importante était de 10 par rapport à la base de référence. La réduction absolue de JCM la plus importante à trois mois était de 22 à 8, alors qu'à 6 mois, la réduction absolue de JCM la plus importante était de 13. Le traitement pouvait être considéré comme cliniquement efficace (≥50 % de réduction de JMM) pour 41 % des patients à 3 mois et environ 44 % des patients à 6 mois. Conclusions: Malgré la variabilité importante des valeurs de la base de référence, cet examen confirme l'efficacité des AcM anti-CGRP, qui ont donné lieu à une réduction importante d'un point de vue clinique du nombre de JMM et de JCM.

Adherence, persistence and treatment switching in psoriasis.

Aim: This study aims to investigate drug utilization patterns in the treatment of psoriasis (PsO) from 1 to 5 years in a real-life setting with Adalimumab (Ada), Etanercept (Eta), Ustekinumab (Ust), Golimumab (Gol), Ixekizumab (Ixe), Secukinumab (Sec) and Apremilast (Apr). Materials & methods: Data from an observational study were used to calculate adherence using the Proportion of Days Covered (PDC) method and persistence. Results & conclusion: Treatment adherence was found to be good for all the drugs studied across all years of analysis, while persistence was suboptimal, showing a marked decrease from the third year of study onward. In the treatment of PsO, greater attention needs to be paid to treatment persistence.

This summary explains that when a patient follows their doctor's medication instructions and continues using the same medication over time to treat a condition like psoriasis, they can expect safer and more effective outcomes. This study examined these aspects to assess how different medications perform over the long term and to explore ways to improve their prescription. The findings highlight that the main issue is not so much in following instructions but in continuing to use the same medication throughout the treatment duration. Raising awareness among healthcare professionals about these issues is crucial to help patients maintain consistent therapy over time and improve their care pathway.

The stimulation of dendritic cells by amyloid beta 1-42 reduces BDNF production in Alzheimer's disease patients.

Dendritic cells (DCs), the main actors of immune responses and inflammation, may play a role in Alzheimer's disease (AD). Recent studies demonstrate that monocyte-derived DCs (MDDCs), generated in vitro in the presence of amyloid ß1-42 peptide (Aß1-42), show a functional alteration and an increased production of inflammatory molecules. Accordingly, MDDCs from AD patients show a more pronounced pro-inflammatory profile than DCs obtained from control subjects. In this study, we aimed at further investigating DC role in AD. Thus, we analyzed the in vitro effect of Aß1-42 treatment on already differentiated DCs from AD patients, as compared to control subjects. We found that Aß1-42 significantly decreases the expression of brain-derived neurotrophic factor (BDNF) in DCs derived from AD patients but not from control subjects. Thus, possibly due to their Aß-induced reduction of neurotrophic support to neurons, DCs from AD patients might contribute to brain damage by playing a part in Aß-dependent neuronal toxicity.

Great Sustainability Results From Appropriate Antihypertensive Therapy.

Cardiovascular diseases are emerging as a major cause of death and hospitalization in the Western world. For many years, a number of medicines have been placed on the market, in well-established and safe use for antihypertensive therapy. The various classes of antihypertensives in established use include, ACE inhibitors, as monotherapy or in combination with diuretics or calcium antagonists, sartans, calcium antagonists, beta blockers, and diuretics. Among these medicines classes there are differences in mechanism of action, efficacy in reducing blood pression, tolerability, and cost. In fact, there are wide differences in the monthly cost of therapy within each class and among the classes themselves. In this analysis we describe an example about the prescribing trends of antihypertensive drugs at a European sample represented by an Italian health care company of about 1 million inhabitants. Aspects of pharmacoeconomics, pharmacoutilization, and pharmacological differences are described.

The diabetic patient between sustainability and effectiveness of new treatments.

Objectives: The increased issuance and distribution of new agents for type 2 diabetes mellitus, due to relaxed prescribing rules, has resulted not only in a greater proximity of treatments to the patient, as envisioned by post-Covidio 19 European policies, but also in an unexpected increase in healthcare spending. Methods: An analysis of a database called "Health Card" was performed in order to evaluate all prescriptions for the new classes of medications used for type 2 diabetes. Results: New legislation called "note 100" was introduced in early 2022, outlining the eligibility of certain categories of drugs used for the treatment of type 2 diabetes mellitus for direct prescription by primary care physicians in Italy. This investigation therefore delves into an examination of the prescribing patterns related to these drugs, contrasting the year 2021, prior to the implementation of Note 100, with the year 2022, following the incorporation of the new legislation. The result resulted in an exponential increase in prescriptions and consumption (+ 38%) and increased healthcare spending of more than three million euros for these drug categories. Conclusion: This analysis highlights how regulation on the one hand leads to facilitating prescribing to meet a population need that is not fully satisfied, but on the other hand leads to increased prescribing and increased health care expenditures that may likely mask phenomena of prescribing inappropriateness.
