Prior researches have suggested that home-based subcutaneous immunoglobulin (SCIG) is equally effective and can be less expensive than hospital-based intravenous immunoglobulin (IVIG) in treating chronic inflammatory demyelinating polyneuropathy (CIDP) patients. This economic evaluation aims at comparing costs of SCIG vs IVIG for CIDP patients in Italy. A 1-year model-based cost-minimization analysis basically populated via neurologists' opinion was undertaken from a societal perspective. Health care resources included immunoglobulin; drugs for premedication and complications (rash, headache, and hypertension) management; time of various health care professionals; pump for SCIG self-administration; infusion disposables. Non-health care resources encompassed transport and parking; losses of working and leisure time for patients and caregivers. Unit or yearly costs for resources valuation were mainly obtained from published sources. Costs were expressed in Euro (<euro>) 2013. An extensive one-way sensitivity analysis (OWSA) and a scenario SA tested the robustness of the base case findings. Overall costs per patient amount to <euro>49,534.75 (SCIG) and <euro>50,895.73 (IVIG); saving in favour of SCIG reaches <euro>1360.98. For both SCIG and IVIG, the cost driver was immunoglobulin (94.06 vs 86.06 % of the overall costs, respectively). Sensitivity analyses confirmed the consistency of the baseline results. SCIG may be a cost-saving therapy for Italian CIDP patients.
