In-State versus Out-of-State Ophthalmic Telemedicine Utilization during the COVID-19 Pandemic

Abstract

Purpose :
During the COVID-19 pandemic, regulatory changes in the United States allowed physicians to practice telemedicine across state lines. Data on the use of interstate ophthalmic telemedicine during the pandemic are limited. We aimed to evaluate the geographic characteristics and interstate utilization of telemedical care as compared to in-person care at a tertiary eye care center during the pandemic.

Methods :
In this single-center, retrospective, cross-sectional study at Massachusetts Eye and Ear (MEE) from January 1 to December 31, 2020, clinical encounters were reviewed to extract patient and visit characteristics. In-person versus telemedical visit types were identified based on institutional categories and billing codes. Residential zip codes were used to estimate geographic characteristics of patients including distance from MEE and in-state versus out-of-state status. Pearson chi-squared tests were used to compare telemedical and in-person care groups.

Results :
A total of 1911 telemedical patients (2262 encounters) and 65763 in-person patients (147211 encounters) were included. The median (interquartile range; IQR) age of telemedicine patients was 61 (43-72) years, 62% of which were female. The median (IQR) age of in-person patients was 63 (49-72) years, 58% of which were female. Telemedicine patients included 14.7% (n=281) out-of-state patients, as compared to 12.0% (n=7876) out-of-state in-person patients (p<0.001). Regarding distance, 42.5% of telemedicine patients and 47.5% of in-person patients lived <10 miles (p<0.001), 41.9% and 41.3% lived 10-50 miles (p=0.611), 8.8% and 7.0% lived 51-100 miles (p=0.002), 3.9% and 2.5% lived 101-250 miles (p<0.001), and 3.0% and 1.8% lived >250 miles (p<0.001) away from MEE, respectively.

Conclusions :
A significantly greater proportion of telemedical care, as compared to in-person care, was provided to out-of-state patients at a large eye care center during the pandemic. Moreover, a significantly greater proportion of telemedical care was utilized by patients living further away from the eye center. Proposals to revert to pre-pandemic policies requiring in-state telemedicine could set back forward progress made during the pandemic, including negative impacts on access to care and continuity of care for established patients. Expanded telemedicine licensure and scope could help advance the efficiency and deployment gains seen during the pandemic.
