Testing the Accuracy of Administrative Case Definitions to Identify Thalassemia

Key Points

• Accurately identifying transfusion-dependent thalassemia is feasible using administrative claims data.
• Nontransfusion-dependent thalassemia cases are difficult to define with precision according to the study.
• Extending the method to other health care databases may yield a national prevalence estimate for thalassemia.
• Finding effective case definitions can enhance identification and treatment pathways for thalassemia patients.
