Treatment costs associated with hospital-based intravenous immunoglobulin therapy compared to home-based subcutaneous immunoglobulin therapy in a cohort of paediatric patients with primary immunodeficiency

Methods This is a retrospective study on a cohort of patients with PID. Annual costs associated with IVg therapy were assessed for each patient for the year prior to commencing home-based subcutaneous SCIg therapy and the year after for the costs associated with the SCIg therapy. Demographic and clinical information were collected from patient’s chart. Economic data were captured from administrative databases, patients, families, and healthcare providers. Paired t-tests and non-parametric Wilcoxon tests were used to assess the difference in costs.
