The Nuanced Landscape of Telemedicine Services

Synchronous vs. Asynchronous Care

Telemedicine services work in two ways: synchronous (live video calls) and asynchronous (recorded exchanges). Synchronous care allows for real-time interaction. Asynchronous care lets patients send messages, test results, or photos for later review. This is useful for dermatology and prescriptions. Apps or services, like the popular app Nurx, make things easier. They provide medications based on your health information. This helps to reduce wait times, especially for specialized care, like oncology.

A recent JAMA study discusses virtual treatment in cancer care. It also shares important feedback about how doctors feel about remote consultations.

The Art of Virtual Bedside Manner

Telemedicine consultations should feel just as personal as an in-person one. Making eye contact with the camera helps create a real connection, even through a screen. A doctor who listens carefully, repeats key points, and asks follow-up questions shows they are paying attention to concerns.

Clear and simple explanations make it easier to understand diagnoses and treatment plans. A calm and friendly tone can help ease anxiety, and pausing for questions gives time to think and ask anything that isn’t clear. A focused doctor—one without distractions in the background—makes the visit feel more professional and reassuring. These small details help build trust and make virtual care a better experience.

Specialty Telemedicine

Telemed expands access to specialties focused on diagnosis and treatment rather than procedures, including behavioral health, infectious diseases, cardiology, and other cognitive fields.
