Sex-related differences in homebound advanced Parkinson’s disease patients

BACKGROUND: Women with Parkinson’s disease (PD) are more likely to be older, have greater disease severity and comorbidities, and yet are less likely to receive care from a neurologist, as compared with men with PD. Within the PD population, homebound individuals are a particularly vulnerable group facing significant barriers to care, yet within this understudied population, sex-related differences have not been reported. PURPOSE: To identify and describe differences in homebound men and women with advanced PD and related disorders, participating in an interdisciplinary home visit program. PATIENTS AND METHODS: This was an exploratory analysis of homebound patients seen between February 2014 and July 2016 using data collected via in-person interviews and chart review. RESULTS: We enrolled 85 patients, of whom 52% were women. PD was the most common diagnosis (79%), followed by dementia with Lewy bodies (5%), and other atypical parkinsonism (16%). Men were more likely to have a PD dementia diagnosis than women (17.1% vs 2.3%, p=0.03). Women were more likely to live alone (18.1% of women had no caregiver vs 2.4% of men, p=0.05). CONCLUSION: The role of the caregiver in facilitating safe aging-in-place is crucial. Among homebound individuals with advanced PD, women were far more likely to live alone. The absence of a spouse or care partner may be due in part to variable sex-based life expectancies. Our findings suggest that homebound women with advanced PD may face greater barriers to accessing support.
