[Cost analysis in Italy of various strategies for the treatment of Parkinson disease in the advanced phase]

Abstract

Objective: To perform a comparative economic evaluation of therapies--L-dopa drugs, subcutaneous infusion of apomorphine and surgical intervention of Deep Brain Stimulation (DBS)--for the treatment of advanced Parkinson's disease (APD) and to verify the level of assistance guaranteed in Italy to patients affected by APD.

Methods: Literature review and Delphi Panel to collect data about the efficacy of the therapies for the treatment of APD and the use of healthcare resources for such therapies. Field survey to investigate financing mechanisms of the therapeutical alternatives in the Italian regions; cost-analysis over five years (NHS perspective); cost-analysis (hospital perspective) for the initial administration of therapeutic alternatives.

Results: Literature review shows that the reduction of the "off-periods" is 62% for Apomorphine and 80-90% for DBS compared to traditional therapy. The 5-years economic analysis from the NHS perspective shows that the cost of a patients with APD is [symbol: see text] 58.065 if treated with traditional therapy, [symbol: see text] 36.423 (including infusional pump and the drug) with subcutaneous apomorphine and respectively [symbol: see text] 56.489 and [symbol: see text] 41.379 (depending on reimbursement of electrodes and neurostimulator on top of the DRG tariff) with DBS. The field survey, highlighted that Regions which currently reimburse the infusion pump for apomorphine and the electrodes and neurostimulator for DBS--on top of the DRG tariff--are a very limited number.

Conclusions: Apomorphine and DBS in the treatment of APD show higher efficacy and lower costs compared to traditional therapy.
