Importance
While poorer populations have more eye problems, it is not known if they face greater difficulty obtaining eye care appointments.
Objective
To compare rates of obtaining eye care appointments and appointment wait times for those with Medicaid and private insurance.
Design
In this prospective observational study, researchers telephoned a randomly selected sample of vision care providers in Michigan and Maryland stratified by neighborhood (urban vs. rural) and provider type (ophthalmologist vs. optometrist) to request the first available appointment. Appointments were sought for an adult needing a diabetic eye exam and a child requesting a routine eye exam for a failed vision screening. Researchers called each practice twice, approximately 2–7 days apart, once requesting an appointment for a patient with Medicaid, and the other for a patient with BlueCross BlueShield (BCBS), and asked if 1) the insurance was accepted, and if so, 2) when the earliest available appointment was.
Setting
Eye clinics throughout Maryland and Michigan.
Participants
Random sample of 330 ophthalmology and optometry practices.
Main Outcomes and Measures
Rate of successfully made appointments and mean wait time for the first available appointment.
Results
A total of 330 eye care providers were contacted. The sample consisted of ophthalmologists (50%) and optometrists (50%) located in Maryland (53%) and Michigan (47%). The rates of successfully obtaining appointments among callers said to have Medicaid and BCBS were 62% [56%,67%] and 79% [75%,84%] (p<0.001), respectively, for adults, and 45% [40%,51%] and 63% [57%,68%] (p<0.001), respectively, for children. Mean wait time did not vary significantly between BCBS and Medicaid for both adult and child. Factors associated with decreased odds of obtaining an appointment for adults and children included Medicaid insurance, appointment with an ophthalmologist and practice location in Maryland.
Conclusions and Relevance
Callers were less successful in trying to obtain eye care appointments with Medicaid than with BCBS, suggesting a disparity in access to eye care based on insurance status, though confounding factors may have also contributed to this finding. Improving access to eye care professionals for those with Medicaid may improve health outcomes and decrease healthcare spending in the long term.
