Clinical meaning
Standard precautions are the minimum infection prevention practices applied to ALL patient care regardless of suspected or confirmed infection status. They are based on the principle that all blood, body fluids (except sweat), non-intact skin, and mucous membranes may contain transmissible infectious agents. Standard precautions include hand hygiene, use of personal protective equipment (PPE) based on anticipated exposure, respiratory hygiene/cough etiquette, safe injection practices, sterile instruments and devices, and clean and disinfected environmental surfaces. Standard precautions replaced the older concept of universal precautions by extending protection beyond bloodborne pathogens to all potentially infectious materials. Hand hygiene is performed using alcohol-based hand rub (ABHR) or soap and water, with soap and water required when hands are visibly soiled or after caring for patients with Clostridioides difficile or norovirus.
Exam relevance
Risk factors: - Non-compliance with hand hygiene protocols among healthcare workers - Inadequate PPE availability or improper donning/doffing technique - High patient-to-nurse ratios limiting time for infection control practices - Needlestick injuries from unsafe sharps handling - Contaminated environmental surfaces acting as fomite reservoirs
