Telemedicine Call

PHILADELPHIA— A new study from researchers in the Perelman School of Medicine at the University of Pennsylvania and Independence Blue Cross shows that when patients’ primary care doctors were able to photograph areas of concern and share them with dermatologists, the response time for a consultation dropped from almost 84 days to under five hours. In addition, the study did not show any undue increases in utilization or cost that might be prohibitive to making the practice widespread. The findings were published today in Telemedicine and e-Health.

“Telemedicine offers the opportunity to accelerate health care access by getting around infrastructure barriers: namely, heavily booked dermatology practices,” said the study’s senior author, Jules Lipoff, MD, an assistant professor of Clinical Dermatology. “Our study provides evidence that more patients can be cared for with the same amount of resources we’re using now.”

Although this study’s data comes from before the emergence of COVID-19, telemedicine measures like these have taken on a particular importance since the outbreak because of its ability to accommodate social distancing.

“The COVID-19 pandemic has illustrated just how important it is to ensure patients have the ability to access to the care, education and support they need virtually,” said co-author Aaron Smith-McLallen, director of Health Informatics and Advanced Analytics at Independence Blue Cross. “We see a future where more and more of our members will be using digital tools to complement in-person care and are working with our provider partners to make that a reality.”

Lipoff, Smith-McLallen, and their fellow researchers, including lead author Neha Jariwala, MD, a resident in Dermatology, designed the study to implement a shared digital photography service (also known as “Store-and-Forward”) between providers. Previously, similar models had been tested in smaller patient groups – including in the inpatient setting as part of the Penn Medicine Center for Health Care Innovation’s accelerator program in 2013. In this larger study, five primary care practices trained their clinicians to take the photos received over a secure application to a rotation of eight dermatologists for consults. This workflow was used instead of the usual process of referring patients to the next available in-person dermatology appointment.

In the study’s process, once the dermatologists reviewed the pictures of the concerning areas, they then responded to the primary care physician with clinical recommendations, which included a triage determination of whether an in-person visit with a dermatologist was needed. The study’s dermatologists also did these consultations within the course of their regular clinical duties without needing additional dedicated time to the effort.

Overall, 167 patients took part in the study, with a retrospective control group of 1,962 patients for comparison who had followed the traditional consultation system of seeing their primary care doctor, receiving a referral, and then scheduling an in-person appointment with a dermatologist.

In addition to the dramatic reduction in time to consultation, the study also suggested that the difference in total medical costs did not significantly differ between the telemedicine patients and those in the non-telemedicine arm of the study.  Moreover, there was not a significant increase in consults when telemedicine was used compared to the previous process.

The study was conducted from June 2016 until May 2017, well before the COVID-19-related expansion of telemedicine, which was due, in large part, to the relaxation of rules for care reimbursement, traditionally the highest barrier for widespread telemedicine use. However, those changes have been mostly related to video calls with health care providers.

“Video-based telemedicine has been extremely helpful amid the social distancing precautions brought about by the COVID-19 outbreak,” Lipoff explained. “But we also need to look toward how we can expand other forms that may be more efficient in delivering care, such as ‘Store-and-Forward,’ since we’ve shown how effective they can be.”

It is unclear whether many of the changes in telemedicine brought about from the COVID-19 expansion will become permanent. But the researchers hope their study can serve as proof of the viability of photo-based telemedicine for dermatology ­– and other specialties, too.

This study was co-funded by Independence Blue Cross and an Innovation Grant from the Penn Medicine Center for Health Care Innovation.

Other authors include Shivan Mehta; Christopher Snider; Junko Takeshita; and Carrie Kovarik; all of Penn, as well as J. Kyle Armstrong, and Aaron Smith-McLallen, both of Independence Blue Cross.


Penn Medicine is one of the world’s leading academic medical centers, dedicated to the related missions of medical education, biomedical research, excellence in patient care, and community service. The organization consists of the University of Pennsylvania Health System and Penn’s Raymond and Ruth Perelman School of Medicine, founded in 1765 as the nation’s first medical school.

The Perelman School of Medicine is consistently among the nation's top recipients of funding from the National Institutes of Health, with $550 million awarded in the 2022 fiscal year. Home to a proud history of “firsts” in medicine, Penn Medicine teams have pioneered discoveries and innovations that have shaped modern medicine, including recent breakthroughs such as CAR T cell therapy for cancer and the mRNA technology used in COVID-19 vaccines.

The University of Pennsylvania Health System’s patient care facilities stretch from the Susquehanna River in Pennsylvania to the New Jersey shore. These include the Hospital of the University of Pennsylvania, Penn Presbyterian Medical Center, Chester County Hospital, Lancaster General Health, Penn Medicine Princeton Health, and Pennsylvania Hospital—the nation’s first hospital, founded in 1751. Additional facilities and enterprises include Good Shepherd Penn Partners, Penn Medicine at Home, Lancaster Behavioral Health Hospital, and Princeton House Behavioral Health, among others.

Penn Medicine is an $11.1 billion enterprise powered by more than 49,000 talented faculty and staff.
