Clinical Burden and Healthcare Resource Utilization Associated With Managing Transfusion-dependent β-Thalassemia in...

Area of Science:

• Hematology
• Public Health
• Clinical Medicine

Background:

• Transfusion-dependent β-thalassemia (TDT) is characterized by reduced β-globin, ineffective erythropoiesis, and iron overload.
• Patients with TDT require regular red blood cell transfusions (RBCTs) and iron chelation therapy for management.
• Clinical and economic burden in TDT patients in England requires detailed description.

Purpose of the Study:

• To describe the clinical and economic burden in patients with TDT in England.
• To compare mortality rates, clinical complications, and healthcare resource utilization (HCRU) between TDT patients and matched controls.
• To identify age-related differences in outcomes for TDT patients.

Main Methods:

• A longitudinal, retrospective study linking the Clinical Practice Research Datalink (CPRD) with Hospital Episode Statistics.
• Identification of TDT patients based on diagnosis, RBCT frequency, and follow-up duration.
• Exact matching of TDT patients with up to 5 controls for comparison of outcomes.

Main Results:

• TDT patients (n=237) showed significantly higher mortality rates (7.17% vs 1.18%) compared to controls (n=1184).
• Prevalent complications included endocrine disorders and bone issues (osteoporosis, diabetes, hypopituitarism).
• TDT patients exhibited substantially higher HCRU, including prescriptions, outpatient visits, and inpatient hospitalizations.

Conclusions:

• Patients with TDT in England face elevated mortality, significant clinical complications, and high healthcare resource utilization.
• The findings underscore the critical need for innovative therapeutic strategies for TDT.
• Adult TDT patients demonstrated increased mortality, complications, and HCRU compared to pediatric patients.
