Abstract

Background and Objectives There is a need to understand how different factors influence health care utilization for patients with Huntington disease (HD) to maximize benefits of primary and specialty care while minimizing need for costly emergency visits or hospitalizations. The primary objective of this study was to characterize how settings where patients with HD in Northern America receive care change throughout the disease course and determine whether the likelihood of different types of service utilization is influenced by clinical, sociodemographic, and caregiver characteristics. Methods Data from the Enroll-HD study and joinpoint regression were used to assess trends in neurology visits, general practitioner visits, emergency department visits, and inpatient stays over the disease course and as a function of total functional capacity. Generalized estimating equation models were then used to identify factors associated with use of these different services in the 6 months before their study visit. Results Visits from 1,631 participants in the Northern America region from the Enroll-HD study were included in this study. Trends in neurology, emergency, and inpatient visits remained constant over most of the disease duration. For the general practitioner visits, there was an increasing trend in use throughout the course of disease. Clinical factors, such as psychiatric symptoms, functional ability, and comorbidities, were associated with use of multiple types of health care services. Sociodemographic and caregiver factors, such as race or ethnicity, urban or rural residence, and caregiver employment status, were also associated with use of multiple health care services. Discussion Clinical, sociodemographic, and caregiver-related factors were all associated with outpatient, emergent, and inpatient care. This work identifies multiple avenues for future research on how to improve access to and quality of care for patients with HD, specifically relating to reducing the need for emergency visits and inpatient stays and promoting collaboration among primary and specialty clinicians.
