[Direct costs for Parkinson's treatment in private neurology practices in Berlin].

BACKGROUND

Aim of this study was to assess the direct costs of Parkinson's disease (PD) within a 3-month period (i.e. the accounting period for the German statutory health insurance) in 12 neurological outpatient practices in Berlin during 2006.

MATERIAL AND METHODS

A total of 425 patients (age 69.1+/-9.3 years, 185 females) were recruited, and sociodemographic and clinical data were obtained by a specific questionnaire. The distribution of costs was analyzed based on several clinical and patient parameters. The costs were calculated with different approaches: (1) prospectively, with the practices' accounting according to German uniform scales (GoA, EbM) and (2) retrospectively, with questionnaires for the Parkinson's patients. Costs were calculated according to current German guidelines of the statutory health insurance. Clinical parameters were assessed with a questionnaire for physicians.

RESULTS

The direct medical costs totaled 1,667 EUR (range 1,436-1,995 EUR, CI 95%) per patient per 3 months. Charges by physicians were 42 EUR (39-45 EUR, CI 95%) for patients with statutory health insurance and 135 EUR (106-177 EUR, CI 95%) for those with private insurance. Disease severity and disease duration correlated with higher direct medical costs. Motor fluctuations and depression also were major factors influencing cost.

CONCLUSION

Our study emphasizes the large economic burden caused mainly by PD medication and hospitalization. For the first time a direct comparison between costs and actual physicians' reimbursement was possible. In combination with further economic studies, this comparison will help to define shortcomings and excesses in PD health care services.
