Enter the total number of injuries over the time between 100 workers and the total hours worked into the Calculator. The calculator will evaluate the Medical Treatment Injury Frequency Rate. 

Medical Treatment Injury Frequency Rate Formula

MTI = I / HW  * 1,000,000

Variables:

  • MTI is the Medical Treatment Injury Frequency Rate (injuries per million hours)
  • I is the total number of injuries over the time between 100 workers
  • HW is the total hours worked

To calculate Medical Treatment Injury Frequency Rate, divide the number of injuries over the period between 100 works by the total hours worked, then multiply by 1,000,000.

How to Calculate Medical Treatment Injury Frequency Rate?

The following steps outline how to calculate the Medical Treatment Injury Frequency Rate.


  1. First, determine the total number of injuries over the time between 100 workers. 
  2. Next, determine the total hours worked. 
  3. Next, gather the formula from above = MTI = I / HW * 1,000,000.
  4. Finally, calculate the Medical Treatment Injury Frequency Rate.
  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 number of injuries over the time between 100 workers = 500

total hours worked = 30,000

FAQ

What is the significance of calculating the Medical Treatment Injury Frequency Rate?

Calculating the Medical Treatment Injury Frequency Rate (MTI) helps organizations understand the severity and frequency of injuries requiring medical treatment. It is crucial for assessing workplace safety, identifying areas for improvement, and implementing measures to reduce the risk of injuries.

How can organizations use the MTI to improve workplace safety?

Organizations can use the MTI as a benchmark to evaluate the effectiveness of their safety protocols and training programs. By tracking this rate over time, they can identify trends, determine the impact of safety initiatives, and make informed decisions to further reduce the frequency of injuries.

Are there any limitations to using the MTI as a safety indicator?

While the MTI is a valuable tool for measuring the frequency of injuries requiring medical treatment, it does not account for the severity of injuries or near misses. Therefore, it should be used in conjunction with other safety metrics for a comprehensive understanding of workplace safety.

Can the MTI calculation be applied to any industry?

Yes, the MTI calculation can be applied across various industries to measure the frequency of injuries requiring medical treatment. However, the benchmark rates may vary by industry, reflecting different levels of risk and safety standards. It’s important for each organization to consider its specific context when interpreting MTI values.
