Real world evidence: patients with alopecia areata in Italy.

BACKGROUND: This real-world analysis aimed at characterizing patients hospitalized for alopecia areata (AA) in Italy, focusing on comorbidities, treatment patterns and the economic burden for disease management. METHODS: Administrative databases of healthcare entities covering 8.9 million residents were retrospectively browsed to include patients of all ages with hospitalization discharge diagnosis for AA from 2010 to 2020. The population was characterized during the year before the first AA-related hospitalization (index-date) and followed-up for all the available successive period. AA drug prescriptions and treatment discontinuation were analyzed during follow-up. Healthcare costs were also examined. RESULTS: Among 252 patients with AA (mean age 32.1 years, 40.9% males), the most common comorbidities were thyroid disease (22.2%) and hypertension (21.8%), consistent with literature; only 44.4% (112/252) received therapy for AA, more frequently with prednisone, triamcinolone and clobetasol. Treatment discontinuation (no prescriptions during the last trimester) was observed in 86% and 88% of patients, respectively at 12 and 24-month after therapy initiation. Overall healthcare costs were 1715€ per patient (rising to 2143€ in the presence of comorbidities), mostly driven by hospitalization and drugs expenses. CONCLUSIONS: This first real-world description of hospitalized AA patients in Italy confirmed the youth and female predominance of this population, in line with international data. The large use of corticosteroids over other systemic therapies followed the Italian guidelines, but the high discontinuation rates suggest an unmet need for further treatment options. Lastly, the analysis of healthcare expenses indicated that hospitalizations and drugs were the most impactive cost items.

Evaluation of the Impact of Catheter Ablation Procedure on Outcomes and Economic Burden in Patients with Atrial Fibrillation: Real-World Data from Italian Administrative Databases.

A real-world analysis among the Italian population has been carried out to estimate the number of atrial fibrillation (AF) patients undergoing catheter ablation and to evaluate their clinical outcome and economic burden. A retrospective analysis on administrative Italian databases has been performed. Between January 2011 and December 2019, all patients diagnosed with AF were considered and those undergoing catheter ablation were identified. Overall, 3084 (3.54%) of AF patients with at least one catheter ablation were included (mean age 63.2, 67.3% males). A significant decrease in the use of AF-related medications and in hospitalizations, mainly related to AF and heart failure, was observed during the 3-year post-ablation period. The average total cost per patient during the 1-year before ablation period was significantly higher compared to the 1-year post-ablation cost (EUR 5248 vs. 4008, respectively; p < 0.001). After propensity score matching, the overall mortality of patients who underwent ablation was significantly lower compared to that assessed in patients not treated with the procedure (9.386/1000 vs. 23.032/1000 person-year, respectively; p < 0.001). Moreover, the mean total costs were significantly higher in patients who did not undergo ablation compared to those who received ablation (EUR 5516 vs. 4008, respectively; p < 0.001). This real-world data analysis shows that in Italy, although catheter ablation is performed in a minority of AF patients, it is associated with significantly better post-procedure clinical outcomes and a significant reduction in healthcare-related costs.
