Uncovering burden disparity: A comparative analysis of the impact of moderate-to-severe psoriasis and hidradenitis suppurativa.

BACKGROUND: Psoriasis and hidradenitis suppurativa (HS) exhibit distinct clinical features, but no studies have directly compared the health-related quality of life (HRQoL) in patients with moderate-to-severe manifestations of these conditions. OBJECTIVE: To determine which disease is associated with more severe HRQoL impairment. METHODS: Weighted averages of each of the following baseline HRQoL measures were determined and compared between HS and psoriasis populations from 5 clinical trials: Visual Analog Scale (VAS) for pain, Total Work Productivity Impairment, Dermatology Life Quality Index; EuroQOL 5D VAS, and Short Form-36 Health Survey. RESULTS: Compared with patients with psoriasis, patients with HS reported higher scores for VAS-pain (54.3 vs 36.1 [P < .0001]), Dermatology Life Quality Index (15.3 vs 11.3 [P < .0001]), EuroQOL 5D VAS (58.8 vs 50.8 [P < .0002]), and Total Work Productivity Impairment (35.4 vs 18.2). Patients with HS had lower Short Form-36 Health Survey scores than did patients with psoriasis (physical, 39.6 vs 49.0; mental, 41.5 vs 47.5 [both P < .0001]). LIMITATIONS: This analysis was performed using published summary data rather than patient-level data, and weighted pooled averages were compared. CONCLUSIONS: Patients with HS have a higher HRQoL burden than patients with psoriasis. This study clearly documents the needs of patients with HS and the potential impact of medical, scientific, and societal consensus for the development of more effective HS treatments.

Patterns of treatment and costs associated with transfusion burden in patients with myelodysplastic syndromes.

Transfusion dependence (TD) among myelodysplastic syndromes (MDS) patients negatively impacts survival and health-related quality of life. We evaluated cost patterns of MDS care during TD and transfusion independence (TI). MDS patients were identified from a US claims database (2008-2013). TD was defined as ≥2 consecutive 8-week periods with ≥1 claim during each, and no interim 56-day period without transfusion; TI as 8 subsequent transfusion-free weeks; and transfusion frequency as the mean interval between transfusions during the TD period. 13,741 patients were included; 19% were TD and 70% had a mean interval between transfusions of ≤28 days. During a 2-year period, TD patients incurred a mean total cost of $17,815/patient-month; 53% higher for those with ≤28 days ($19,498) vs. >28 days ($12,717) between transfusions. Among patients who achieved TI, mean total cost was $7874/patient-month. For TD-MDS patients, cost increases are proportional to transfusion frequency and achieving TI yields economic benefits.
