A home visit may be conducted by a health care professional other than your doctor (i.e., a nurse or nurse practitioner, a physician assistant, or healthcare technician). You could take a telemedicine (telehealth) call from your study doctor at home using a desktop or tablet computer or a smartphone. Again, this will depend on the study. Some studies may have you interact with the study doctor from your home, via a telemedicine (telehealth) visit over your computer or mobile device. Other studies may monitor you at home with a wearable sensor. Others may ask you to complete surveys or track certain symptoms using a mobile app on your phone. Still others might include a combination of these, along with visits to the study doctor at a clinic or hospital. While there are many ways to participate in a clinical trial at home, the clinical trial program conducting the study will identify the appropriate and available communication and measurement methods for your specific study.
