Definition

Infection control practices applied to all patients regardless of diagnosis, treating all blood and body fluids as potentially infectious.

MA: during phlebotomy, injections, specimen collection, EKG, wound care.

EMT/Paramedic: from scene size-up through patient contact.

Frequently Asked Questions

How do standard differ from transmission-based precautions?
Standard precautions are baseline for ALL patients. Transmission-based (contact, droplet, airborne) are added on top for specific infections.
Why did they replace universal precautions?
Universal precautions only addressed bloodborne pathogens. Standard precautions expanded to all body fluids except sweat.
Is sweat included?
No. Sweat is excluded because it has not been implicated in bloodborne pathogen transmission.
