Inpatient Mortality in Parkinson's Disease

Area of Science:

• Gerontology and Geriatric Medicine
• Neurology
• Palliative Care

Background:

• A significant percentage of Parkinson's disease (PD) patients die in acute care hospitals, contrary to the public's preference for dying at home.
• Identifying trends in clinical and demographic characteristics of PD patients experiencing in-hospital mortality is crucial for targeted interventions.

Purpose of the Study:

• To examine trends in clinical and demographic factors associated with in-hospital mortality among Parkinson's disease patients.
• To identify specific patient populations at higher risk for unwanted inpatient mortality.

Main Methods:

• Analysis of a large cohort (n = 710,013) of Parkinson's disease patients admitted to hospitals between 2002 and 2016 using the National Inpatient Sample.
• Logistic regression models were employed to assess the odds of in-hospital mortality based on clinical and demographic attributes and their temporal changes.
• Key variables included age, length of stay, race/ethnicity, sex, geographic region, severity of illness, and mortality risk.

Main Results:

• Increased age, higher severity of illness, and greater mortality risk were significantly associated with increased odds of in-hospital mortality.
• Factors such as shorter length of stay (≤5 days), white race/ethnicity, and male sex showed higher odds of inpatient mortality.
• While overall fitted probabilities of mortality declined over time, specific demographic and clinical factors continue to influence outcomes.

Conclusions:

• Significant variations exist among Parkinson's disease patient populations concerning the likelihood of in-hospital mortality, and these patterns are evolving.
• Identifying high-risk PD patients for inpatient mortality allows clinicians to proactively address end-of-life care needs more effectively.
• This research highlights the need for tailored strategies to reduce unwanted hospital deaths in the Parkinson's disease population.
