Talking EVS Productivity:
Three Bad, Better, Best Charts Shape the Conversation
STANDARD THINKING MAY OVERLOOK KEY EVS REALITIES
INTRODUCTION:
Getting the most out of your human resources, as close to 100% productivity as possible.
When it comes to hospital Environmental Services departments, one of the most important and frequent topics is staffing levels and productivity. Calling the topic “challenging” is an understatement.
Productivity is often considered mostly a function of patient census. Patient-census staffing models may be well suited to clinical functions, where the work is patient-centric. However, those models overlook other EVS realities in your facility. The total amount of cleanable space in a hospital that needs to be cleaned, sterilized, and kept safe isn’t based solely on the number of patients in beds. Because, while patients may come and go, the facility does not.
There’s the best way to answer questions about EVS productivity.
While calculating productivity may not be the responsibility of the EVS department head, it’s a certainty that they will be asked to maximize it. EVS managers are asked two questions frequently:
- How do you adjust staffing amid fluctuations in the census?
- How do you effectively cover high-census days AND maintain productivity on low-census days?
Below are three charts that shape the conversation and illustrate how EVS managers maximize productivity. One of the charts is a standard, quick misperception that is easy to slip into, especially for those asking the questions from outside the department. One chart is better. And the last chart shows the best way to view productivity.
CHART #1 — Census Centric
Not the best way to look at the entire facility (a Bad model, even).
The Issue: The chart overlooks important realities of Environmental Services management, namely, cleaning not driven by census. These are spaces or activities in healthcare facilities where cleaning requirements do not fluctuate with the daily census. Examples include:
•Emergency • OR • Radiology • Labor & Delivery
• Lock-in Positions • Trash & Linen Disruption
CHART #2 — Add Cleaning Not Driven By Census
A Better model for staffing.

A better model for staffing, the chart illustrates the constant need for cleaning not driven by census. This model, not solely driven by daily patient census, shows a more accurate depiction of staffing requirements, though it still shows daily variation.
This chart adds cleaning not driven by census as a constant need. This addition increases accuracy, because EVS staffing levels are not based solely on patient census.
A Remaining Issue: While required staffing levels are more accurately illustrated in the chart, the daily demand still fluctuates. The reality of fluctuating daily staffing schedules is a detrimental effect on staff morale. Consistent work schedules provide better opportunities for EVS technicians to support their families and build loyalty for the employer. If an employer can’t provide consistency, many employees feel obliged to seek stable work schedules elsewhere.
CHART #3 — Add Cleaning Not Driven By Census and Periodic (Project) Work
The Best model for staffing.
While charts #1 and #2 take into account patient census and cleaning not driven by census, they do not consider a third important EVS need: periodic (project) work.

The best model for staffing productivity shows all three factors that make up staffing demand. By flexing to meet daily patient census and periodic (project) work, the department can maintain the greatest productivity while providing consistent daily hours for staff.
A Natural Solution: It’s likely your EVS department is already flexing project work schedules to make the best use of staff for covering periodic work, or project work.
Chart #3 paints the picture of how periodic work fits into daily staffing to fill the extra time that’s left when census and cleaning not driven by census are lighter. Rather than send staff home, periodic work (which is less time sensitive, yet equally important) can be assigned to fill the extra time capacity.
Consistent daily total cleaning requirements maintain cleaning productivity levels while providing a more consistent work schedule for EVS staff.
