Infection Control · single question
Switching from in-person dental visits to virtual (telehealth) consultations where clinically appropriate is generally classified under which tier of the hierarchy of controls, according to CDC/NIOSH-adapted infection-control guidance?
Show answer and explanation
Correct answer: B. Substitution / Administrative controls (different authoritative sources classify virtual visits slightly differently — most infection-control-specific adaptations place it as an administrative or substitution-level control rather than true elimination, since the underlying hazard/pathogen itself is not removed from existence)
This is a genuinely debated classification point: some general hierarchy-of-controls discussions treat remote/virtual interaction as approaching 'elimination' of exposure for that specific encounter, while CDC/NIOSH-adapted infection-control-specific guidance more often places telehealth/virtual consultation under substitution (replacing an in-person, higher-risk encounter with a lower-risk virtual alternative) or administrative controls (a policy-level change in how care is delivered) — because the underlying infectious hazard itself isn't eliminated from the world, just avoided for that specific encounter.
