This is a study to see whether participation in the Edmond J. Safra Interdisciplinary Home
Visit Program for Advanced Parkinson's (HVP) increases the rate of age-appropriate
vaccinations in people with advanced Parkinson's Disease (PD) and related disorders. This
study will evaluate the impact of the HVP on the rate of common illnesses such as flu and
pneumonia in patients with advanced PD and related disorders over the course of one year.
As there is currently no data available on the baseline rate of vaccinations in either
homebound or less disabled PD populations, investigators will seek to establish the baseline
rate of vaccinations, barriers to getting vaccinated, and baseline healthcare utilization in
these populations by piloting (Phase 1) and then implementing (Phase 2) a survey via
telephone interviews. Investigators will then test feasibility of offering influenza and
pneumococcal vaccinations, as appropriate, to the homebound individuals in our HVP cohort
(Phase 3), and will compare their pre- and post-intervention rates of both outpatient and
acute healthcare utilization and self-reported illness.
