Objective. To detect and explain changing trends in incidence, case fa
tality rates, and mortality for unintentional injuries in the Netherla
nds for the years 1950 through 1995. Methods. Using national registry
data, the authors analyzed trends in traffic injuries, occupational in
juries, and home and leisure injuries, Results. Between 1950 and 1970,
mortality from unintentional injuries rose, reflecting an increasing
incidence of injuries. This was followed by a sharp decline in mortali
ty due to a decreasing incidence combined with a rapidly falling case
fatality rate. Starting in the second half of the 1980s, the decline i
n mortality leveled off as the incidence of several injury subclasses
once again rose. The observed trends reflect several background factor
s, including economic fluctuations (influencing exposure), preventive
measures (reducing injury risk and injury severity), and improvements
in trauma care (lowering the severity-adjusted case fatality rate). Co
nclusions. injury mortality can be reduced through measures that lower
injury risk, injury severity, or severity-adjusted case fatality rate
s. Beginning in the mid-1980s, such compensatory mechanisms have falle
n short in the Netherlands. New policies are needed despite the impres
sive reductions in mortality already reached.
