Abstract
BACKGROUND: Hospitalization in Parkinson's disease (PD) is associated with reduced quality of life, caregiver burden and high costs. However, no large-scale studies of rate and causes of hospitalizations in patients with PD have been published. OBJECTIVE: To investigate the rate and reasons for hospitalization and factors associated with hospitalization among people with PD compared to the general population. METHODS: We examined rate and causes of admission in PD patients and matched controls in The Health Improvement Network from 2006 to 2016. Multivariable Poisson regression was used to explore the effects of age, gender, social deprivation, urbanicity and practice geographic location on hospitalization. RESULTS: In longitudinal data from 9,998 newly diagnosed individuals with PD and 55,554 controls without PD aged≥50years, 39%of PD patients and 28%of controls were hospitalised over a median follow-up 5.1years. The adjusted incidence rate ratio(IRR) of hospitalization in PD compared to controls was 1.33(95%CI:1.29-1.37) and rose with increased follow-up duration. Hospitalization rate was overall higher in the older age groups, but the adjusted IRR of hospitalization compared to controls was highest in the youngest age group. PD patients were more often admitted with falls/fractures, infections, gastrointestinal complications, PD, dementia, psychosis/hallucinations, postural hypotension, electrolyte disturbances, stroke and surgical procedures and slightly less often due to hypertension. CONCLUSION: People with PD have an increased hospitalization rate compared to controls, particularly in the younger age groups, and it increases with longer disease duration. The complications of motor and non-motor features of PD are amongst the main reasons for admission, some of which could be managed preventatively to avoid admissions.
