Telemedicine in health surveillance: possibilities and limits

Telemedicine uses communication technologies to provide certain healthcare activities remotely. Its potential use in health surveillance requires professional judgement, an authorised organisation and suitability for the risks. A video call or questionnaire does not automatically replace a health examination or its necessary tests.

In brief

Remote care can facilitate contact where appropriate, but requires professional selection, privacy and continuity. In health surveillance, it does not remove tests, examinations or legal requirements. Limits and an in-person pathway must be defined when circumstances require them.

Start with the healthcare need

WHO presents telemedicine as a service requiring planning, implementation and maintenance. Technology should be chosen to meet a care need, rather than become the programme’s objective.

In the workplace context, identify the problem to be addressed: difficulty accessing care, follow-up or communicating information. Healthcare professionals must then assess which activity can be performed remotely. There is no universal equivalence between remote consultation and in-person examination for every exposure or individual.

Maintain the health surveillance framework

Spain’s Prevention Services Regulations require surveillance to be linked to work risks and provide for an occupational medical history, examination and investigations according to those risks. Royal Decree 843/2011 regulates the resources and organisation of healthcare activity.

Changing the channel does not remove those requirements. Knowledge of the job, professional competence and the health programme must be maintained. A tool that only collects answers does not assume responsibility for interpreting results or deciding whether further action is needed.

Recognise when the channel is insufficient

Remote care has limits when it cannot obtain the necessary information, perform an examination or ensure suitable communication conditions. Those limits must be defined before the service is offered.

As a design criterion, provide for in-person referral, connection interruptions and situations requiring a different response. Explain how the person can request help and what happens if the professional considers the consultation insufficient. Do not present the system as an emergency channel if it is not organised for that purpose.

Protect identity, privacy and documentation

The AEPD notes that access to health information must be justified by professional functions. The same requirement applies to video calls, messaging and remote documentation.

Verify identity, avoid spaces where others can listen and use channels with appropriate safeguards. Do not record consultations by default without assessing necessity and the legal basis. Document the activity in the relevant record, including significant limitations of the channel. The employer does not need access to the clinical conversation to demonstrate that an activity took place.

Evaluate quality and actual access

Implementation requires checking results and difficulties, not just travel savings. Review failed connections, referrals, understanding and continuity. Offer alternatives when accessibility, language or digital skills hinder care.

Agreeing a pathway also means defining who reviews messages and under what conditions. An unassigned inbox can create care expectations the service cannot meet. Reduced administrative time must not be confused with evidence that the entire healthcare activity retains its quality.

Hypothetical example: follow-up with an in-person option

A service considers conducting a follow-up contact remotely, having first been selected by the professional. The person receives access and privacy instructions. During the conversation, information emerges that requires an in-person examination.

The professional arranges that care and records the limitation of the remote activity. No conclusion is issued on insufficient information. The digital channel facilitates initial contact, while the clinical decision maintains the scope and quality the situation requires.
