Abstract
INTRODUCTION: Homebound individuals with advanced Parkinson's disease (PD) are underrepresented in research and care. We tested the impact of interdisciplinary, telehealth-enhanced home visits (IN-HOME-PD) on patient quality of life (QoL) compared with usual care. METHODS: Nonrandomized controlled trial of quarterly, structured, telehealth-enhanced interdisciplinary home visits focused on symptom management, home safety, medication reconciliation, and psychosocial needs (ClinicalTrials.gov NCT03189459). We enrolled homebound participants with advanced PD (Hoehn & Yahr (HY) stage ≥3). Usual care participants had ≥2 visits in the Parkinson's Outcomes Project (POP) registry. We compared within- and between-group one-year change in QoL using the Parkinson's Disease Questionnaire. RESULTS: Sixty-five individuals enrolled in IN-HOME-PD (32.3% women; mean age 78.9 (SD 7.6) years; 74.6% white; 78.5% HY ≥ 4) compared with 319 POP controls, with differences in age, race, and PD severity (37.9% women; mean age 70.1 (7.8) years; 96.2% white; 15.1% HY ≥ 4). Longitudinally, the intervention group's QoL remained unchanged (within-group p = 0.74, Cohen's d = 0.05) while QoL decreased over time in POP controls (p < 0.001, Cohen's d = 0.27). The difference favored the intervention (between-group p = 0.04). POP participants declined in 7/8 dimensions while IN-HOME-PD participants' bodily discomfort improved and hospice use and death at home-markers of goal-concordant care-far exceeded national data. CONCLUSIONS: Telehealth-enhanced home visits can stabilize and may improve the predicted QoL decline in advanced PD via continuity of care and facilitating goal-concordant care, particularly among diverse populations. Extrapolating features of this model may improve continuity of care and outcomes in advanced PD.
