In other cases, they may be able to provide initial advice remotely but still want to see the patient. For a patient with severe acne, “I may be able to tell the referring doctor: ‘Please start the patient on these three medicines. It will take 2 months for those medicines to start working and then we will plan to have an in-person dermatology visit.’ ” In this case, telemedicine essentially replaces one in-person visit.
If photographs are poor, the differential diagnosis is broad, a procedure is required, the doctor needs to touch the lesion, or more involved history taking or counseling are required, the patient may need to go into the office.
Beyond its public health advantages during a pandemic, telemedicine can improve access for patients who live far away, lack transportation, or are unable to take time off from work. It also can decrease patient wait times. “Once we started doing some telemedicine work … we went from having a 5-month wait time for patients to see us in person to a 72-hour wait time for providing some care for patients if they had good photos as part of their referral,” Dr. Venkatesan said.
Telemedicine has been used in inpatient and outpatient dermatology settings. Primary care providers who consult with dermatologists using a store-and-forward telemedicine system may improve their dermatology knowledge and feel more confident in their ability to diagnose and manage dermatologic conditions, research indicates .
In obstetrics and gynecology, telemedicine may play a role in preconception, contraception, and medical abortion care, prenatal visits, well-woman exams, mental health, and pre- and postoperative counseling, a recent review suggests.
Image quality is key
“Quality of the image is so critical for being able to provide good care, especially in such a visual exam field as dermatology,” Dr. Venkatesan said.
To that end, doctors have offered recommendations on how to photograph skin conditions. A guide shared by the mobile telehealth system company ClickMedix suggests focusing on the area of importance, capturing the extent of involvement, and including involved and uninvolved areas.
Good lighting and checking the image resolution can help, Dr. Venkatesan offered. Nevertheless, patients may have difficulty photographing themselves. If a patient is with their primary care doctor, “we are much more likely to be able to get good quality photos,” she said.
Dr. Venkatesan is a paid consultant for DirectDerm, a store-and-forward teledermatology company. Dr. Mauskar had no relevant disclosures.
