EVALUATING ON-DEMAND INTERPRETER AVAILABILITY AND ITS INFLUENCE ON ACCESS TO CARE IN RURAL PRIMARY CARE SETTINGS

Abstract

Limited English proficiency (LEP) remains a significant barrier to equitable access to healthcare in the United States, particularly in rural primary care settings where resource constraints and workforce shortages already limit service availability (U.S. Census Bureau, 2022; Probst et al., 2004). While professional interpreter services are known to improve communication, patient safety, and quality of care (Flores, 2005; Karliner et al., 2007), less is understood about how interpreter availability models influence operational access metrics. This quantitative capstone project evaluated whether on-demand interpreter services are associated with improved timeliness of care compared with scheduled interpreter-only models in rural primary care clinics. Using retrospective operational data, the study examined two key outcomes: time-toappointment and visit start-time delays among LEP patients. Findings demonstrated that clinics utilizing on-demand interpreter services experienced shorter intervals between appointment request and scheduled visit, as well as reduced delays in visit initiation. These results suggest that interpreter availability functions as a structural determinant of access to care, influencing both scheduling efficiency and clinic workflow. The findings support the integration of on demand interpreter modalities as an evidence-informed strategy to improve operational performance and advance health equity (Jacobs et al., 2004). Implications for healthcare administrators include the need for standardized language access protocols, investment in interpreter infrastructure, and alignment with federal language access requirements (U.S. Department of Health and Human Services [HHS], Office of Civil Rights, 2025). Further research is recommended to evaluate long-term clinical and financial outcomes associated with interpreter service models.
