Enter the total time (hrs) and the patient care time (hrs) into the Calculator. The calculator will evaluate the Fallow Time. 

Fallow Time Formula

FT = TT - PCT

Variables:

  • FT is the Fallow Time (hrs)
  • TT is the total time (hrs)
  • PCT is the patient care time (hrs)

To calculate Fallow Time, subtract the patient care time from the total time.

How to Calculate Fallow Time?

The following steps outline how to calculate the Fallow Time.


  1. First, determine the total time (hrs). 
  2. Next, determine the patient care time (hrs). 
  3. Next, gather the formula from above = FT = TT – PCT.
  4. Finally, calculate the Fallow Time.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total time (hrs) = 20

patient care time (hrs) = 15

FAQs

What is Fallow Time?

Fallow Time refers to the period between the end of patient care and when the space can be safely used again. In the context of healthcare, it’s the time allowed for potential contaminants to settle or be removed, ensuring a safe environment for the next patient.

Why is calculating Fallow Time important in healthcare settings?

Calculating Fallow Time is crucial for infection control and maintaining a safe environment for both patients and healthcare workers. It helps in scheduling and ensuring that rooms are adequately cleaned and ventilated before being reused.

Can Fallow Time vary between different healthcare settings?

Yes, Fallow Time can vary significantly depending on the type of care provided, the layout of the facility, ventilation systems, and the specific protocols of a healthcare setting. Different procedures may also require different Fallow Times due to varying risks of aerosol generation.

Are there any tools or technology that can help reduce Fallow Time?

Yes, advancements in cleaning and air filtration technologies can help reduce Fallow Time. For example, the use of UV-C light for disinfection or HEPA air filtration systems can improve the turnover rate of treatment rooms by reducing the time needed to safely remove contaminants.
