Real-world analysis of the economic and therapeutic burden in advanced breast cancer patients in Italy.

BACKGROUND: This real-world analysis evaluated drug utilization focusing on wastage and healthcare costs for treatment of patients with advanced breast cancer (aBC) hormone receptor-positive (HR+)/human epidermal growth factor receptor-2 negative (HER2-) in Italy. METHODS: A retrospective analysis was conducted on administrative data covering about 13.3 million health-assisted individuals. Across January/2017-June/2021, all patients with HR+/HER2-aBC were identified by ≥ 1 prescription for cyclin-dependent kinase 4/6 inhibitors (CDK 4/6i). Cost analysis was performed and updated referring to the prices of November 2021. RESULTS: Overall, 3,647 HR+/HER2-aBC patients were included (2,627 palbociclib treated, 729 ribociclib treated, and 291 abemaciclib treated). After 12 months of follow-up, 35% of palbociclib patients had a dose reduction (on average 8.9 wasted pills/patient), 44.7% of abemaciclib patients had a dose reduction (on average 6.7 wasted pills/patient), 22.1% of ribociclib patients had a dose reduction (no wasted pills). Therapy wastage added up to 528,716€ for palbociclib-treated patients (524€/patient) and 5,738€ in abemaciclib-treated patients (151€/patient). No wastage was attributed to ribociclib. CONCLUSIONS: Dose reduction was associated with drug wastage in palbociclib and abemaciclib-treated patients, but not in ribociclib-treated ones. These findings might be helpful to policy decision-makers who, for healthcare strategies implementation, among several variables should consider the possible restraining of drug wastage.

Iron deficiency anemia impacts disease progression and healthcare resource consumption in patients with inflammatory bowel disease: a real-world evidence study.

Background: Iron deficiency anemia (IDA) is a common extraintestinal manifestation of inflammatory bowel disease (IBD), affecting around one-third of patients. Objective: To compare IBD progression and healthcare resource utilization in patients with and without a co-diagnosis of IDA in a real-world setting. Design: A retrospective comparative study was conducted using Italian entities' administrative databases, covering 9.3 million health-assisted individuals. Methods: Adult IBD patients diagnosed with ulcerative colitis and/or Crohn's disease were enrolled between January 2010 and September 2017. Within 12 months from IBD diagnosis, IDA was identified by at least one prescription for iron and/or IDA hospitalization and/or blood transfusion (proxy of diagnosis). IBD population was divided according to the presence/absence of IDA. Given the nonrandom patients' allocation, propensity score matching (PSM) was applied to abate potential unbalances between the groups. Before and after PSM, IBD progression (in terms of IBD-related hospitalizations and surgeries), and healthcare resource costs were assessed. Results: Overall, 13,475 IBD patients were included, with an average age at diagnosis of 49.9 years, and a 53.9% percentage of male gender. Before PSM, 1753 (13%) patients were IBD-IDA, and 11,722 (87%) were IBD-non-IDA. Post-PSM, 1753 IBD-IDA patients were matched with 3506 IBD-non-IDA. Before PSM, IBD progression was significantly higher in IBD-IDA (12.8%) than in IBD-non-IDA (6.5%) (p < 0.001). After PSM, IBD progression and IBD-related hospitalizations were significantly (p < 0.001) more frequent in IBD-IDA patients (12.8% and 12.0%, respectively) compared to IBD-non-IDA (8.7% and 7.7%). Consistently, healthcare expenditures resulted significantly higher among IDA patients (p < 0.001), with an overall mean annual cost of €5317 compared to €2798 for patients without IDA. These results were confirmed after PSM matching, as the mean annual total cost/patient in IBD-IDA versus IBD-non-IDA were €3693 and €3046, respectively (p < 0.001). Conclusion: In a real-life setting, IDA co-diagnosis in IBD patients was associated with disease progression and higher related economic burden.

Economic burden of subsequent fracture in osteoporosis patients in South Korea.

OBJECTIVES: This study aimed to assess the economic burden of subsequent fracture in osteoporosis patients with incident fracture. METHODS: The authors conducted a retrospective cohort analysis of the South Korean national health insurance claims data. Study subjects included osteoporosis patients aged ≥50 with incident fracture (July 1, 2014-June 30, 2015). Fracture-related 1-year healthcare cost was evaluated after incident fracture for patients with and without subsequent fracture, defined as a fracture occurring within 2 years from incident fracture at a different site or at the same site after 6-months washout period. Per-patient-per-month (PPPM) cost was calculated by dividing each patient's cumulative healthcare cost until subsequent fracture with time-to-subsequent-fracture. For the patients without subsequent fracture, PPPM cost equaled 1-year monthly cost. A generalized linear model (GLM) was used to estimate the ratio of increase in healthcare cost to assess the economic impact of subsequent fracture. RESULTS: A total of 73,717 osteoporosis patients with incident fracture were identified, consisting of 52.1% vertebral, 1.9% hip, and 46.0% non-vertebral-non-hip fractures. Subsequent fracture occurred in 17.9% of patients with average time-to-subsequent-fracture of 256 days. Patients with subsequent fracture had significantly higher 1-year healthcare cost after incident fracture than those without subsequent fracture ($4,307 vs $1,721) and the difference was greater in PPPM cost ($930 vs $141). GLM analysis showed that having subsequent fracture increased both 1-year healthcare cost and PPPM cost by 1.91-fold (95% CI = 1.87-1.95) and 6.14-fold (95% CI = 5.99-6.28), respectively. CONCLUSIONS: Subsequent fracture imposes a substantial burden on osteoporosis patients and, therefore, more efforts are needed for preventing subsequent fracture among osteoporosis patients.
