Hospital Environmental Services FAQ

Below are the most frequently asked questions surrounding environmental services at hospitals and other healthcare facilities.

What is EVS?

EVS stands for environmental services and refers to the custodial department in a hospital or other healthcare setting.

What do EVS technicians in a hospital do?

EVS hospital technicians are responsible for the cleanliness of all areas of the facility. Their duties extend far beyond such basics as floor and restroom care. They are on the frontline of infection prevention throughout the medical facility. They play a major role in reducing healthcare acquired infections (HAIs), which the CDC estimates account for an estimated 1.7 million infections and 99,000 associated deaths each year. EVS technicians also are integral to the overall patient experience. A good EVS team can help increase HCAHPS scores, which account for 25% of a hospital’s Total Performance Score.

Why do HCAHPS scores matter?

HCAHPS scores are the result of patient satisfaction surveys regarding the care they received in a hospital. The Centers for Medicare & Medicaid Services (CMS) requires every U.S hospital to administer these surveys, and the scores are directly tied to CMS reimbursement. The government developed HCAHPS to help ensure that hospitals provide patients with a safe, comfortable healthcare experience.

  • Infection prevention and COVID-19 response
  • Floor care

What are some top challenges for EVS in a hospital?

The many challenges for EVS hospital technicians include:

Do EVS services differ from hospital to hospital?

EVS can differ depending on various factors, including size, geographic location, throughput, and specialty/scope of work. For example, EVS may have to replace linens and perform cleaning and disinfecting more frequently for a hospital with a busy emergency department or deal with more sharps in hospitals where people regularly receive COVID-19, flu, and other vaccinations. Similarly, EVS workers at a children’s hospital may encounter more food stains, while a hospital in a retirement area may experience lower throughput due to extended patient stays. However, basic infection-prevention procedures and other EVS protocols are virtually the same in all hospitals.
