LTIFR (lost time injury frequency rate) is the number of lost time injuries occurring in a workplace per 1 million hours worked. An LTIFR of 7, for example, shows that 7 lost time injuries occur on a jobsite every 1 million hours worked. The formula gives a picture of how safe a workplace is for its workers.
A 1991 study showed that in confined spaces the relationship was significantly different: 1.2 minor injuries for each serious injury or death. [7] A broad study of UK accident data in the mid-1990s showed a relationship of 1 fatality to 207 major injuries, to 1,402 injuries causing three or more days lost time injuries, to 2,754 minor injuries.

The DALY relies on an acceptance that the most appropriate measure of the effects of chronic illness is time, both time lost due to premature death and time spent disabled by disease. One DALY, therefore, is equal to one year of healthy life lost. How much a medical condition affects a person is called the disability weight (DW). This is ...

[2] [8] Continuous exercise or movement of a musculoskeletal injury can result in chronic inflammation with progression to permanent damage or disability. [9] In many cases, during the healing period after a musculoskeletal injury, a period in which the healing area will be completely immobile, a cast-induced muscle atrophy can occur.
The total time taken for all waiting drivers to react and accelerate is the start-up lost time. Clearance lost time is the time lost to stopping a line of vehicles at the end of a green phase. Lost time is always measured in seconds. Start-up lost time can be calculated as the sum of the differences between the headways for the first cars in ...
Sentinel events include "unexpected occurrences involving death or serious physical or psychological injury, or the risk thereof". [1] They also include the following, even if death or major loss of function did not occur: Infant abduction; Release of an infant to an incorrect family; Unexpected death of an infant not born prematurely
There are factors for a near miss related to the operator, and factors related to the context. Fatigue is an example for the former. The risk of a car crash after a more than 24h shift for physicians has been observed to increase by 168%, and the risk of near miss by 460%. [4]
