Analysis of Performance

Note: This historical data of this metric changes in subsequent time periods because injury data is tied to the date of injury regardless of when treatment occurs or the case changes from recordable to time away restricted, or transferred. For example, if an employee has an injury in March but he does not seek medical treatment until June, it will be captured on March's OSHA log and it will not show up on the June log. National benchmark data for any year is only available in September of the following year. There is an approximate 18 month lag time in current available national benchmark data from the Bureau of Labor Statistics.

The Data for Q1 is year to date rate calculation.

The DART rate is an OSHA calculation for the number of recordable incidents (per 100 full-time employees) that results in:

  • One or more days away from work
  • One or more days of restricted work or job transfer

It is calculated by taking the total number of DART incidents and multiply by 200,000. Because this is a factor per 100 full-time employees, 200,000 is used because that represents 100 employees working 40 hours a week for a 50 week calendar year. Then, divide this number by the total number of hours worked by all employees.

Many of our injuries requiring lost time or job transfer resulted from slips/trips and falls on ice and snow. 

Proactive measures were in place to improve department availability to winter traction aids however supply shortages and delays were a limiting factor. 

Metric Definition
The Days Away Restricted or Transferred (DART) rate calculation is based upon the number of work related injuries and illnesses severe enough to cause an employee to be temporarily reassigned or miss work completely in relation to the total number of employee hours worked. This is a nationally recognized standard safety metric. Current-year benchmarks are not available as they are published by the Bureau of Labor Statistics and have an approximate 18 month lag time.
Why Is This Important?
DART rate is important because it is a nationally benchmarkeable measure widely accepted as representative of injury severity in the workplace.  It is important for the City to provide a safe workplace for all employees and the only way to achieve that is by driving a culture of proactive safety built on continuous improvement.  As safety efforts drive down injuries and injury severity, the costs associated with workers' compensation claims can be driven down as well.  The reduction of days away, restricted or transferred is directly related to reduction in lost productivity as well as lost efficiency because only workgroups that are whole can operate at optimal performance.
City Organization Impact on Performance

High – Reducing the DART rate requires the City to reduce the number of injuries that result in days away, restricted or transferred. Getting employees back to work quickly and efficiently following injuries enables to the City to spend less money on benefits used to keep employees who are off or on modified duty whole. Many studies have led to the well accepted fact that employees who return to work quickly following an injury rehab faster, better, and more completely than those who do not.  Driving down injuries that impact the DART rate requires workgroups to be engaged and to actively interact with injured workers to get them back to work as efficiently as medically possible.  This engagement in conjuction with other ongoing proactive safety efforts has concrete and continuous impact on improving the City's safety culture.

Benchmark Information
This metric contains General Industry and Public Entities benchmark data. The General Industry benchmark gives overall context to the City's performance, while the Public Entities benchmark allows for a closer comparison that accounts for the unique challenges that face local governments.
