COVID-19 Patient Management in Outpatient Setting: A Population-Based Study from Southern Italy.

Evidence on treatments for early-stage COVID-19 in outpatient setting is sparse. We explored the pattern of use of drugs prescribed for COVID-19 outpatients' management in Southern Italy in the period February 2020-January 2021. This population-based cohort study was conducted using COVID-19 surveillance registry from Caserta Local Health Unit, which was linked to claims databases from the same catchment area. The date of SARS-CoV-2 infection diagnosis was the index date (ID). We evaluated demographic and clinical characteristics of the study drug users and the pattern of use of drugs prescribed for outpatient COVID-19 management. Overall, 40,030 patients were included in the analyses, with a median (IQR) age of 44 (27-58) years. More than half of the included patients were asymptomatic at the ID. Overall, during the study period, 720 (1.8%) patients died due to COVID-19. Azithromycin and glucocorticoids were the most frequently prescribed drugs, while oxygen was the less frequently prescribed therapy. The cumulative rate of recovery from COVID-19 was 84.2% at 30 days from ID and it was lower among older patients. In this study we documented that the drug prescribing patterns for COVID-19 treatment in an outpatient setting from Southern Italy was not supported from current evidence on beneficial therapies for early treatment of COVID-19, thus highlighting the need to implement strategies for improving appropriate drug prescribing in general practice.

How did the Introduction of Biosimilar Filgrastim Influence the Prescribing Pattern of Granulocyte Colony-Stimulating Factors? Results from a Multicentre, Population-Based Study, from Five Italian Centres in the Years 2009-2014.

BACKGROUND: Granulocyte colony-stimulating factors (G-CSFs) are biological products for which the main indication of use is chemotherapy-induced neutropenia. Biosimilars of G-CSFs have been available in Europe since 2007. OBJECTIVE: The objective of this study was to investigate the prescribing pattern of G-CSFs in five Italian centres using different healthcare policy interventions to promote the use of biosimilars in routine care. METHODS: This retrospective, population-based drug utilization study was conducted during the years 2009-2014 using the administrative databases of the Caserta, Treviso and Palermo Local Health Units (LHUs) and the Tuscany and Umbria regions. G-CSF users were characterized and the prevalence of use, proportion of biosimilar users and switching pattern of different G-CSFs were evaluated over time and across centres. RESULTS: Overall, 30,247 patients were treated with G-CSFs in the years 2009-2014, of which 29,083 (96.2 %) were naïve users. The overall prevalence of G-CSF use increased from 0.8 per 1000 inhabitants in 2009 to 1.1 per 1000 in 2014. An increase in the proportion of the use of the biosimilar filgrastim by the total G-CSF users was observed in all centres: from 0.2 % (2009) to 66.2 % (2014). However, heterogeneity across different centres was reported, with the largest increase in Treviso LHU (from 0 to 89.1 % from 2009 to 2014). During the first year of treatment, switching between different G-CSFs was frequent (20.3 %). CONCLUSIONS: Heterogeneity in the use of G-CSF and, in particular, biosimilar filgrastim across different Italian centres was observed, probably due to different regional healthcare policy interventions. During the first year of treatment, switching between different G-CSFs was frequent. Considering the impact of biological drugs on pharmaceutical expenses, it is necessary to harmonize healthcare policies promoting the use of biological drugs with the lowest cost.

[Evaluation of therapeutical appropriateness in psychiatric treatment of schizophrenia, by integrating computer data records with clinical audit results]. / Valutazione dell'appropriatezza prescrittiva in psichiatria: un progetto di clinical audit nella ASL di Caserta.

AIM: The aim is to evaluate prescriptive patterns of atypical antipsychotic drugs for the treatment of schizophrenia in the LHU Caserta in 2011-2013, and to indicate potentially inappropriate therapy; to plan or schedule corrective/preventive activities to support the continuous improvement of health services. METHODS: Retrospective cohort study, based on integration of health records and clinical audit. The study was performed in the following steps: data retrieval and analysis; comparison of data with international literature; editing of the Diagnostic-Therapeutic Path. The analysis was performed by using the administrative database of drug prescriptions and treatment plans in the SANIARP portal, a web platform available to specialist facilities and private and public pharmacies of LHU Caserta. The subject of our analysis was to gain information about the diagnosis and treatment of users of atypical antipsychotics in the LHU of Caserta in the years 2011-2013. RESULTS: We identified 2,768 patients with at least one prescription of atypical antipsychotics and diagnosis coded in the study period. Schizophrenia is the most frequent diagnosis (31.1%) and the most common drug in use is olanzapine (29.1%). About 70% of schizophrenics were on monotherapy with no change in drug, 23.6% were under polytherapy and 7.9% made a switch. DISCUSSION AND CONCLUSION: Our findings were a starting point for editing Diagnostic and Therapeutic Paths aimed at raising the awareness of the scientific community about the appropriateness of diagnosis and treatment in schizophrenia. Pharmacological treatment of schizophrenia should be focused on improving the overall quality of life aimed at remission and possible recovery, although difficult.
