Telediagnosis

Telediagnosis is the medical diagnosis issued by a clinician who is geographically remote from the patient, enabled by telecommunications and information technologies that transmit clinical data for assessment. It is a core component of telemedicine and can involve diagnoses based on patient history, remotely collected examination findings, medical images, and physiological or sensor data.

Common methods include store-and-forward transmission of data such as digital photographs, radiographs, pathology slides, or ECG traces, and real-time videoconferencing where clinicians review information during a live consultation. Telediagnostic applications span specialties such as radiology (teleradiology), pathology, dermatology, ophthalmology, and cardiology.

Data used in telediagnosis include clinical history, digital images, video, audio, laboratory results, and data from wearable devices or home monitoring systems. Advanced systems may integrate electronic health records and decision-support tools to aid interpretation, sometimes with artificial intelligence assistance.

Potential benefits include expanded access to expertise, faster triage and diagnosis, reduced patient travel, and more efficient resource use. Challenges include ensuring data privacy and security, maintaining data quality, interoperability, and navigating regulatory and reimbursement frameworks. Limitations arise when a physical examination, auscultation, or hands-on assessment is essential, or when data are incomplete or of poor quality.

Telediagnosis has developed alongside telemedicine, with early forms in teleradiology and telepathology dating to the late 20th century. Its adoption depends on infrastructure, interoperability, training, and clear guidelines to safeguard patient safety and data protection.
