Rural Ambulatory Access for Semi-Urgent Care and the Relationship of Distance to an Emergency Department.
BACKGROUND
Availability of timely access to ambulatory care for semi-urgent medical concerns in rural and suburban locales is unknown. Further distance to an emergency department (ED) may require rural clinics to serve as surrogate EDs in their region, and make it more likely for these clinics to offer timely appointments. We determined the availability of urgent (within 48 hours) access to ambulatory care for non-established visiting patients, and assessed the effect of insurance and ability to pay cash on a patient's success in scheduling an appointment in rural and suburban Eastern United States. We also assessed how proximity to EDs and urgent care (UC) facilities influenced access to semi-urgent ambulatory appointments at primary care facilities.


METHODS
The Appalachian Trail, which runs from Georgia to Maine, was used as a transect to select 190 rural and suburban primary care clinics located along its entire length. We calculated their location and distance to the nearest hospital-based ED or UC via Google Earth. A sham patient representing a non-established visiting patient called each clinic over a four-month period (2013), requesting an appointment in the next 48 hours for one of three scripted clinical vignettes representing common semi-urgent ambulatory concerns. We randomized the scenarios and insurance statuses (insured vs. uninsured). Each clinic was contacted twice, once with the caller representing an insured patient, once with the caller representing an uninsured patient. When the caller was representing an uninsured patient, any required upfront payment was requested from each clinic. One hundred dollars was used as a cutoff between the uninsured as a distinction between those able to afford substantial upfront sums and those who could not. To determine if proximity to other sources of care impacted a clinic's ability to grant an appointment, distance to the nearest ED or UC was modeled as a dichotomous variable using 30 miles as the divider.


RESULTS
Of 380 requests, 96 (25.3%) resulted in appointments within 48 hours. Insured patients and uninsured patients able to pay a substantial amount upfront (>$100) were more likely to book an appointment (p-value <0.001, OR 18, CI [5-154]). Of the 47 clinics that granted uninsured patients appointments 89.3% required some form of payment up front. Farther distances from an ED did not result in greater likelihood of an appointment (OR 1.7, CI [0.4-11.3]). Clinics located within 30 miles of an UC were more likely to grant an appointment (OR 2.45, CI [1.19-5.80]).


CONCLUSIONS
Almost 75% of rural clinics were unable to grant a new appointment for a semi-urgent health complaint. Lack of insurance and large upfront charges appear to be significant barriers to rural ambulatory care appointments. Greater distance from an ED does not improve a clinic's ability to see semi-urgent appointments. Clinics located near an UC were more likely to grant an appointment than clinics without close alternative outpatient healthcare options.
