Background: In an increasingly economically oriented healthcare system the analysis of disease-specific costs is becoming more and more relevant, especially in chronic diseases with long duration of hospitalization. As a frequent neurodegenerative disease idiopathic Parkinson's disease (IPD) causes high healthcare costs. The pathognomonic affection of mobility and equilibrium often leads to fall-related fractures in the course of the disease, which cause further costs through hospitalization and possibly surgical treatment.
Objective: The aim of the study was the calculation of inpatient treatment costs of fall-related fractures in IPD as well as the analysis of relevant cost-causing factors. In addition, an alternative calculation of the treatment costs was carried out with the question of potential remuneration problems in the current diagnosis-related groups (DRG) system.
Methods: The basis of this retrospective, single center analysis was the actual revenue of 95 patients treated between January 2011 and January 2018 at the University Hospital Frankfurt am Main. The proceeds were systematically reviewed for relevant demographic, healthcare and disease-related aspects and statistically analyzed for cost-related factors using univariate analysis. The alternative calculation of the treatment costs was carried out according to commonly used health economics methods.
Results: The median revenue per patient and injury was 9295 € (±8038 €, median 7148 €) with a mean length of stay of 13.5 days (±7.2 days, median 13 days). The alternative calculation of treatment costs per patient was an average of 9789 € (±6423 €, median 8906 €). High treatment costs were associated with age >75 years (p = 0.028), surgical treatment (p = 0.004), intensive care unit (ICU) stay (p = 0.004), limb fractures (p = 0.028) and an advanced stage of IPD (p = 0.028). Significant differences between actual revenue and calculated costs were found for hospital stays ≥14 days (p = 0.009) and advanced stages of disease (p = 0.036).
Conclusion: The costs of care in patients with IPD and fall-related fractures are high and relevant to health economics. In general, remuneration based on the DRG system seems to largely cover the costs; however, compensation problems arise especially for patients with a long duration of hospitalization or advanced IPD.
