In Depth

EVS teams handle room turnovers, terminal cleaning, waste management, and high-touch disinfection under healthcare-specific procedures. The term signals that cleaning in a clinical setting is an infection-control function, not just janitorial labor.

Why It Matters

EVS performance directly affects infection rates, patient safety, and hospital quality scores. It is a specialized, higher-skilled discipline that commands different staffing and pricing than office cleaning.
