title: The economic impact of Parkinson's disease. An estimation based on a 3-month prospective analysis.
abstract: OBJECTIVE
  This study prospectively assesses the medical costs of Parkinson's disease (PD).
  
  
  METHODS
  Over a period of 3 months (from July to September 1995), patients with PD documented all items of healthcare provision. These data were then used to calculate medical costs for an individual patient as well as the costs of PD.
  
  
  METHODS
  We included 20 outpatients with idiopathic PD from the neurological outpatient clinic, Klinikum Grosshadern, Munich, and 20 patients from two office-based neurologists in South-West Germany.
  
  
  RESULTS
  The mean 3-month medical cost of PD in 1995 deutschmarks (DM) was 5210 ($US3390, 2240 Pounds) consisting of DM1410 ($US920, 610 Pounds) for care and nursing, DM1580 ($US1030, 680 Pounds) for drug therapy, DM1320 ($US860, 570 Pounds) for inpatient hospital care, DM40 ($US26, 17 Pounds) for outpatient care and DM860 for other expenses ($US560, 370 Pounds). The expenditure was related to the disease evolution. Patients complaining of one-sided symptoms [Hoehn and Yahr stage I; (HY I)] were less expensive to treat (DM1930, $US1250, 830 Pounds) than patients who were severely incapacitated (HY V) [DM9740, $US6330, 4200 Pounds; HY V]. After 3 to 5 years of levodopa treatment approximately 50% of patients start to experience fluctuations in motor ability and dyskinesias [Unified Parkinson's disease rating scale, part IV (UPDRS IV)]. This onset of motor complications parallels an increase in costs. For patients who experienced motor fluctuations, annual costs were DM6550 ($US4260, 2820 Pounds) compared with DM3030 ($US1960, 1300 Pounds) for patients lacking this problem. Indirect non-medical costs were not calculated due to the limited number of patients. The impact of the disease on work, however, is clearly apparent from the patients' history: 19 out of 34 patients who had already stopped working attributed this to the disease, and only 6 patients were still working at the time of the survey.
  
  
  CONCLUSIONS
  PD poses a major financial impact to society which is expected to increase in future years as the age distribution shifts to older age groups. On the basis of a prevalence of PD of 183 per 100,000, we calculated an annual expenditure of DM3.0 billion for the direct medical costs of PD in Germany.
