The use of telemedicine, such as logging on to a health care provider’s online service to seek treatment for a sinus infection, grew nearly 7-fold in Minnesota between 2010 and 2015 according to a new University of Minnesota School of Public Health study.
“Telemedicine has the potential to expand access to timely care and reduce costs relative to in-person care. However, little has been known about who is using telemedicine,” said lead author and PhD student Ms. Jiani Yu. “In our new study, we found rapid growth of telemedicine use in Minnesota between 2010 and 2015 and rates varied extensively by health insurance coverage type and rurality.”
There are three main types of telemedicine services being used in Minnesota:
The researchers discovered the patterns of telemedicine use in the state by analyzing patient information from the Minnesota All Payer Claims Database. The study included data from urban and rural patients of all ages using most sources of health insurance coverage, including public health insurance.
Overall, the study showed telemedicine consultations with patients or other providers increased from 11,113 to 86,238 between 2010 and 2015.
The study also found:
Ms. Yu said the rural-urban differences in the way telemedicine is being used are probably primarily due to the specific benefits provided by the major type of insurance used by people in those areas and not driven by clinical need.
“Our results suggest that coverage policies and provider reimbursement are important factors determining which patients receive telemedicine and the types of telemedicine provided,” said Ms. Yu.
Ms. Yu also said the findings may suggest the most beneficial aspects of telemedicine vary depending on the type of telemedicine visit. Patient-initiated online visits, which occur primarily in metropolitan areas, may be used to avoid the inconvenience of visiting brick-and-mortar clinics. Real-time telemedicine services, which occur primarily in rural areas, may help publicly insured patients to remotely seek treatment from specialists practicing in distant locations.
“Telemedicine is an important innovation in care delivery,” said Dr. Abraham. “This study provides us with a comprehensive understanding about volume trends, the types of patients obtaining telemedicine services, and the types of providers delivering them. This work provides a valuable foundation for additional research to understand how telemedicine use affects cost, quality and access to care for Minnesotans. ”
The research team is continuing to analyze telemedicine data in the Minnesota All Payer Claims Database, and is studying the impact of telemedicine visits on follow-up costs, utilization, and quality of care.
