RESUMO
Purpose: A retrospective analysis of real-world data was performed to assess the epidemiology and economic burden of multiple sclerosis (MS), relapsing-remitting MS (RRMS), and secondary-progressive MS (SPMS) in Italy. Patients and Methods: An observational study on administrative databases from a sample of Italian entities was carried-out. Between 01/2010-12/2017, patients with ≥1 MS diagnosis code (ICD-9-CM:340 and/or exemption code:046) and/or ≥1 disease-modifying therapies (DMTs) prescription, were included. Among MS-cohort, SPMS patients were identified by ≥2 hospitalizations or by ≥2 drug prescriptions related to MS progression. MS patients not fulfilling SPMS criteria were included as RRMS. Mean annual healthcare costs were reported during follow-up and stratified by DMT treatment/untreatment. Results: Overall, 9543 MS patients were included; 8397 with RRMS and 1146 with SPMS. Estimated prevalence of MS was 141.6/100,000 inhabitants (RRMS 124.4/100,000 and SPMS 17.2/100,000). Mean annual cost for untreated and treated patient was respectively: 3638 and 11796 (MS-cohort), 3183 and 11486 (RRMS-cohort), 6317 and 15511 (SPMS-cohort). The first-line DMT treatment duration averaged 27.4 ± 22.8 months; the mean cost was 19004 for the whole period. The second-line DMT treatment lasted on average 31.1 ± 24.5 months; the mean cost was 47293 for the whole period. Conclusion: This study provided insights into the MS epidemiology in Italy and its economic burden. Healthcare costs associated with MS management were mainly driven by DMTs expenditure. A trend of higher healthcare-resource consumption was observed among SPMS-cohort.
RESUMO
This Italian retrospective study aimed to analyze the pharmaco-utilization of anti-VEGF drugs and health care costs among patients with wet age-related macular degeneration (wAMD) or other ocular diseases. A retrospective analysis was performed on administrative databases of Italian entities covering approximately six million individuals. Across January 2010-December 2017, patients aged ≥50 years with a prescription of intravitreal anti-VEGFs were included as "wAMD" patients [by wAMD hospitalization or intravitreal injections] or as "other ocular diseases" patients [by hospitalization for other ocular disorders or intravitreal injections, with concomitant diabetes diagnosis or dexamethasone treatment]. The date of first matching of inclusion criteria was index-date. wAMD-cohort. Overall, 3879 patients were included; at index-date, 82.2% were treated with Ranibizumab, 15.8% with Aflibercept, and 2% with Pegaptanib. During the follow-up, the mean/annual anti-VEGF prescription [3.6 (first-year)-0.8 (third-year)] and the total expenditure [5799.84 (first-year)-3212.84 (third-year)] decreased. Other ocular diseases-cohort. Overall, 2646 patients were enclosed; 85.9% were treated with Ranibizumab, 13.5% with Aflibercept, and 0.6% with Pegaptanib. During the follow-up, the mean/annual anti-VEGF prescription [3.3 (first-year)-0.5 (third-year)] and the total cost [7196.83 (first-year)-5162.68 (third-year)] decreased. This observational study highlighted a decline in anti-VEGF prescriptions over time in both cohorts, suggesting a trend of under-treatment that could worsen the patients' clinical outcomes and increase health care resource consumption.
