While telemedicine can grow dramatically over the next decade and help healthcare professionals, it still offers specific technical and practical challenges. For a long time, telemedicine has been centered on technology.
Furthermore, combining various technologies may result in massive data flows that are neither useful nor easy to manage (e.g., continuous monitoring of temperature and blood pressure) Certain constraints may impede the adoption, deployment, and scaling up of telemedicine and related technologies. It will take considerable training to guarantee that patients are comfortable with video teleconsultations and the usage of assistive technologies. Additionally, physicians require subspecialty-specific technological, clinical, and communication training. Moreover, access to broadband and Internet facilities is a significant barrier to telemedicine deployment in rural and under-resourced settings.

Telehealth requires stable broadband access, which is not always feasible for remote clinics and patients. When telemedicine technology is used, legal limits and a lack of clarity about what is permissible are possible, and these restrictions encourage telemedicine providers to exercise prudence. Certain conditions are not covered under health system legislation.

When adopting technologies and procedures to close gaps in the healthcare system, it is critical to question whether the gaps exist and establish the standards and goals of care and iterate toward these standards and ideals. Telemedical consultations fall short of the fidelity that an in-person physical exam provides in physical examinations, body language, verbal intonation, and scents. The commitment of the technology used in telemedical consultations must be constantly improved to achieve the same level of fidelity and information as an in-person visit.
