Real-world assessment of myelodysplastic syndrome: Japanese claims data analysis

Aim: To describe the treatment landscape and associated economic burden for myelodysplastic syndrome in Japan. Methods: We studied nationwide retrospective claims data from 2008 to 2019. The study cohort was categorized into patients receiving transfusion, erythropoiesis-stimulating agent, erythropoiesis-stimulating agent + transfusion, azacitidine, azacitidine + transfusion and others. Results: Our study found that the azacitidine + transfusion group had the highest medical cost and severity of disease compared with the other groups. In those patients, healthcare resource utilization and the costs of transfusions, including iron chelation therapy, increased medical costs. Conclusion: Our retrospective analysis provides a current snapshot of real-world treatment patterns and associated incremental economic costs of iron chelation therapy with the presence of transfusions that drive an increase in total costs.

Spinal cord stimulation: a real-world data analysis on outcomes and differences between rechargeable and non-rechargeable implantable pulse generators

Objective In this analysis, we examined differences between rechargeable and non-rechargeable spinal cord stimulation (SCS) devices in patients with pain. Methods We conducted a retrospective, longitudinal claims data analysis using a German research database comprising 5 million statutory insured patients (2012–2017). Outcomes of demographics, patient pathways, and health care resource utilization (HCRU) in patients with initial SCS were collected. Results Of 150 patients in the database, 73 (49%) received a rechargeable device and 77 (51%) a non-rechargeable device. The average age was 62.5 years (51% female and 49% male patients). A significant decrease over a 3-year follow-up was observed in analgesic prescriptions (−18%), number of patient visits to a physician, and number of patients who were hospitalized. HCRU-related figures for patients with non-rechargeable neurostimulators increased in the last follow-up year whereas the group receiving rechargeable neurostimulators showed a steady decrease. Conclusions SCS seems to be an effective way for patients with chronic pain to decrease pain and improve quality of life. Rechargeable devices seem to be superior to non-rechargeable devices owing to greater longevity and were found to be associated with continuous reduction of pain diagnoses, hospitalization, physician visits, and use of pain medication in our study.
