Publication date: September 2016 Source:Journal of Clinical Neuroscience, Volume 31 Author(s): Abhimanyu Mahajan, Poojitha Balakrishnan, Achint Patel, Ioannis Konstantinidis, Dominic Nistal, Narender Annapureddy, Priti Poojary, Girish N. Nadkarni, Christos Sidiropoulos The total number of people living with Parkinson’s disease (PD) worldwide is expected to double by 2030. The risk factors for emergency department visits in PD patients have been described before, however, there is limited data on inpatient hospitalizations of PD patients. We derived our study cohort from the Nationwide Inpatient Sample (NIS) database from 2002–2011. The NIS is a stratified 20% sample of discharges from all U.S. hospitals. We extracted causes of hospitalization using International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM) codes and calculated inpatient mortality, length of stay and cost. Further, the significance of trends over 10 years was assessed. A total of 3,015,645 (weighted) admissions of PD patients were documented from 2002–2011. Pneumonia, urinary tract infection (UTI), septicemia and aspiration pneumonitis were the most common causes of admission, of which incidence of sepsis and UTI was trending up. Of all causes, 3.9% of the admissions resulted in inpatient mortality. Inpatient mortality for PD patients decreased from 4.9% in 2002 to 3.3% in 2011 (p<0.001). The median length of stay has also steadily declined from ...
