The importance of monitoring is in knowing how many injuries
occur, when they occur, and to whom they occur! Injury
monitoring or injury surveillance is very important, because it
identifies the relative importance of injuries as a problem and
lays the foundation for efforts to reduce injuries in the future.
All of the injury control measures that quickly come to mind,
e.g. seat belts, airbags, helmets, were implemented after it
became apparent that injuries were occurring in relatively high
numbers and we needed to do something about it.
