ABSTRACT

AIM: This study evaluated real-world healthcare resource utilization (HCRU), direct costs, and overall survival (OS) of patients who were Medicare beneficiaries and were newly diagnosed with myelofibrosis (MF) who filled ≥1 prescription of ruxolitinib versus those who did not. PATIENTS AND METHODS: This was a study of the US Medicare fee-for-service database. Beneficiaries were aged ≥65 years with an MF diagnosis (index) between January 1, 2012 - December 31, 2017. Data were summarized descriptively. OS was estimated using Kaplan-Meier analysis. RESULTS: Patients with ≥1 prescription fill of ruxolitinib (n = 2,787) had lower mean rates (per patient per month [PPPM]) versus patients who did not fill a prescription for ruxolitinib (n = 7,262) for hospitalizations (0.16 vs 0.32), length of inpatient stay (0.16 vs 2.44 days), emergency department visits (0.10 vs 0.14), physician office visits (4.68 vs 6.25), skilled nursing facility stays (0.02 vs 0.12), home health/durable medical equipment services (0.32 vs 0.47), and hospice visits (0.30 vs 1.70). Monthly medical costs were numerically lower in patients who had ≥1 fill of ruxolitinib versus those who did not fill a prescription for ruxolitinib ($6,553 vs $12,929), largely driven by inpatient costs ($3,428 vs $6,689). Pharmacy costs were $10,065 and $987 in patients who filled versus did not fill ≥1 prescription for ruxolitinib, respectively; total PPPM all-cause healthcare costs were $16,618 and $13,916, respectively. The median OS was 37.5 and 18.7 months for the cohorts of patients who filled versus did not fill ≥1 prescription for ruxolitinib, respectively (hazard ratio = 0.63, 95% CI = 0.59 - 0.67). CONCLUSIONS: Ruxolitinib is associated with reduced HCRU and direct costs of medical care in addition to increased survival, suggesting it to be a cost-effective advance for patients with MF.


Myelofibrosis is a rare bone marrow cancer. People with this disease do not live as long as the general population. They have difficult symptoms, can tire easily, and may have a large spleen that can be uncomfortable. Ruxolitinib is a treatment for myelofibrosis that can improve symptoms and help patients live longer.This study asked how treating patients with ruxolitinib affected three things. (1) How often do they go to a healthcare provider? (2) How much do they spend on their healthcare? (3) How long do they live? The authors looked at Medicare records to answer these questions.The study found that treated patients visited hospitals, doctors' offices, and other services less often. When they did require hospital care, they stayed in the hospital for a shorter amount of time. As a result, treated patients spent about half as much on these services. However, patients treated with ruxolitinib spent more at the pharmacy. Finally, treated patients lived about twice as long as those who were never treated with ruxolitinib. These findings suggest that ruxolitinib is worthwhile for patients with myelofibrosis.

ABSTRACT

Purpose: To quantify the effects of moderate and/or severe chronic obstructive pulmonary disease (COPD) exacerbations on future exacerbations and healthcare costs in Medicare Fee-For-Service beneficiaries. Patients and Methods: A retrospective cohort study of patients ≥40 years of age, with continuous enrollment from 2015 to 2018, with an index COPD diagnosis defined as first hospitalization, emergency department visit, or first of two outpatient visits (≥30 days apart) in 2015 with a claim for chronic bronchitis, emphysema, or chronic airway obstruction. Patients were stratified by baseline exacerbation categories in year one (YR1) and subsequently evaluated in YR2 and YR3: (A) none; (B) 1 moderate; (C) ≥2 moderate; (D) 1 severe; and (E) ≥2, one being severe. Moderate exacerbations were defined as COPD-related outpatient/ED visits with a corticosteroid/antibiotic claim within ±7 days of the visit and severe exacerbations as hospitalizations with a primary COPD diagnosis. Total all-cause costs for Categories B-E were compared to reference Category A using generalized linear models and inflation adjusted to 2019 dollars. Results: A total of 1,492,108 patients met study criteria with a mean (±SD) age of 70.9±10.9. In YR1, nearly 40% of patients experienced ≥1 moderate and/or severe exacerbations. Patients having multiple exacerbations, regardless of severity were 2-4 times more likely to experience an exacerbation during YR2 and YR3. Adjusted costs ranged between $24,000 and $26,600 for all categories for YR2 and YR3. Adjusted YR2 costs for Category D and E were $1421 and $1548 higher than those without an exacerbation (Category A YR2 $25,084, YR3 $24,282; p<0.0001). The respective YR3 adjusted costs were $2062 and $2117 higher than those without an exacerbation (Category A; p<0.0001), representing an increase of 6-8% and 8-9% for YR2 and YR3. Conclusion: Medicare patients with recent moderate or severe exacerbations, or at least two exacerbations per year are at significant risk for future exacerbations and incur higher all-cause costs.

ABSTRACT

Patients with polycythemia vera (PV) and essential thrombocythemia (ET) have increased thrombotic risk. This retrospective, real-world analysis of Medicare patients (age ≥ 65 years) newly diagnosed with high-risk PV or intermediate-/high-risk ET compared mortality risk among those with versus without thrombotic events during the study period. Patients diagnosed with PV or ET with ≥ 1 inpatient or ≥ 2 outpatient claims (January 1, 2010-December 31, 2017; index was date of first qualifying claim) were included. The study included 50,405 Medicare beneficiaries with PV and 124,569 with ET. During follow-up (median [range]: PV, 34.5 [0-97.3] months; ET, 25.5 [0-97.4] months), 14,334 patients (28.4%) with PV and 30,478 (24.5%) with ET experienced thrombotic events (most commonly ischemic stroke [PV, 46.0%; ET, 42.5%]. Mortality risk was increased for patients with versus without post-index thrombosis for both PV (adjusted hazard ratio [aHR; 95% CI], 18.6 [16.1-21.6]; P < 0.001) and ET (aHR [95% CI], 25.2 [23.1-27.5]; P < 0.001). Median survival was shorter for patients who experienced a thrombotic event ≤ 1 year post-index versus those who did not (PV, 5.1 years vs not reached; ET, 3.7 vs 6.7 years; both P < 0.001). These findings highlight the importance of thrombosis risk mitigation in PV and ET management.

ABSTRACT

The Janus kinase inhibitor ruxolitinib is approved for the treatment of myelofibrosis (MF) and improved overall survival (OS) versus control therapy in the phase 3 COMFORT trials. The aim of this retrospective analysis was to examine the real-world impact of ruxolitinib on OS in patients with MF. The US Medicare Fee-for-Service claims database (parts A/B/D) was used to identify patients with ≥ 1 inpatient or ≥ 2 outpatient claims with an MF diagnosis (January 2010-December 2017). Eligible patients with MF were ≥ 65 years old (intermediate-1 or higher risk based on age). Patients were divided into 3 groups based on ruxolitinib approval status at diagnosis and ruxolitinib exposure: (1) preapproval, ruxolitinib-unexposed; (2) post-approval, ruxolitinib-unexposed; and (3) post-approval, ruxolitinib-exposed. In total, 1677 patients with MF were included (preapproval [all ruxolitinib-unexposed], n = 278; post-approval, n = 1399 [ruxolitinib-unexposed, n = 1127; ruxolitinib-exposed, n = 272]). Overall, median age was 78 years, and 39.8% were male. Among patients with valid death dates (preapproval, n = 119 [42.8%]; post-approval, ruxolitinib-unexposed, n = 382 [33.9%]; post-approval ruxolitinib-exposed, n = 54 [19.9%]), 1-year survival rates were 55.6%, 72.5%, and 82.3%, and median OS was 13.2 months, 44.4 months, and not reached, respectively. Risk of mortality was significantly lower post- versus preapproval regardless of exposure to ruxolitinib (ruxolitinib-unexposed: adjusted hazard ratio [HR], 0.67; ruxolitinib-exposed: adjusted HR, 0.36; P < 0.001 for both); post-approval, mortality risk was significantly lower in ruxolitinib-exposed versus ruxolitinib-unexposed patients (adjusted HR, 0.61; P = 0.002). Findings from this study complement clinical data of ruxolitinib in MF by demonstrating a survival benefit in a real-world setting.

ABSTRACT

BACKGROUND: Emerging trial data for treatment of COVID-19 suggest that in addition to improved clinical outcomes, these treatments reduce length of hospital stay (LOS). However, the economic value of a shortened LOS is unclear. OBJECTIVE: To estimate incremental costs per day of hospitalization for a patient with influenza or viral pneumonia, as a proxy for COVID-19; ICU costs associated with invasive mechanical ventilation (iMV) were also determined. METHODS: Retrospective analysis of claims-based data was conducted using the IBM MarketScan® Commercial Claims and Encounters and Medicare Supplemental and Coordination of Care and the Medicare Fee-for-Service claims databases for hospitalizations due to influenza/viral pneumonia between January 2018 and June 2019. Cases were stratified as uncomplicated hospitalizations or with ICU. Ordinary least squares regression, excluding LOS or costs exceeding the 99th percentile (base case), was used to estimate incremental costs per day; a sensitivity analysis included all qualified hospitalizations. Additional sensitivity analyses used weighting methodology. RESULTS: Among 6055 and 118,419 hospitalizations in the commercially insured and Medicare databases, respectively, 5958 and 116,552 hospitalizations, respectively, represented the base case. Estimated incremental base case costs per additional inpatient day were $2158 and $3900 in the commercial population for uncomplicated hospitalizations and hospitalizations with ICU, respectively, and $475 and $668, respectively in the Medicare population. Estimated incremental base case costs per additional ICU day were $5254 and $608 for Commercial and Medicare populations, respectively. Higher absolute costs were estimated in the sensitivity analysis on all qualified hospitalizations; the weighted sensitivity analyses generally showed that estimates were stable. Use of iMV increased costs by $35,482 and $13,101 in the commercial and Medicare populations, respectively. CONCLUSION: The incremental daily cost of a hospitalization is substantial for US patients with commercial insurance and for Medicare patients. These findings may help quantify the economic value of COVID-19 treatments that reduce LOS.
