Travel Cost Savings and Practicality for Low-Vision Telerehabilitation.

INTRODUCTION
Veterans with low vision who live in rural communities have limited access to low-vision rehabilitation services, unless they are able to travel several miles to a specialty low-vision clinic. A low-vision optometry telerehabilitation evaluation is a thorough assessment of patient's functional vision. Following each low-vision optometry telerehabilitation evaluation is a low-vision telerehabilitation initial assessment with a blind rehabilitation therapist. Our objective was to estimate the acceptance and practicality of low-vision telerehabilitation and investigate the travel cost and time savings.


METHODS
Utilizing Google Maps™, round-trip travel mileage and travel time can be estimated between the veteran's home and the Buffalo Veterans Affairs (VA) and compared with the round-trip mileage and travel time between the veteran's home and local community-based outpatient center (CBOC) or local VA for low-vision telerehabilitation services. The difference is the savings in travel miles and time. Cost saving can be calculated by multiplying difference in travel miles by cost per mile.


RESULTS
Veterans who chose not to schedule face-to-face low-vision rehabilitation at the Buffalo VA due to an average round-trip travel distance of 151 miles scheduled a low-vision telerehabilitation at a local CBOC or local VA with an average round-trip travel distance of 29 miles. Adding low-vision telerehabilitation services from fiscal year (FY) 13 to FY 17 resulted in a 24% increase in low-vision patient care. The median saving of travel miles for rural veterans was 122 miles per veteran, and the median saving of travel time was 2.09 h per veteran. Overall, the median saving of the travel cost was $65.29 per veteran.


CONCLUSIONS
This study shows and supports low-vision telerehabilitation as an accepted, practical, time-saving, and cost-saving alternative option to traditional face-to-face consultations with a low-vision optometrist and blind rehabilitation therapist.
