A lost time injury (LTI) refers to any injury sustained on the job by an employee which results in that employee being absent from at least a full day of work. The time off does not include the day of the injury. If the employee has the following day off, then the injury is classified as a lost time injury.
A medical treatment case (MTC) or medical treatment injury (MTI), on the other hand, is any injury sustained on the job that requires medical treatment from a professional physician or qualified paramedic. It does not include on-the-job first aid treatment. A medical treatment case does not necessitate time off work beyond the date of the injury to be classified as such.
So, to summarize:
- An o
ccupational injury qualifies as an LTI if it results in the injured employee needing at least one full day off from work
- An occupational injury qualifies as an MTC if it results in the injured employee needing professional medical treatment
