Percent Distributionof Inpatient Discharges by Intent of Injury,
ArizonaResidents, 2013
In 2013, injury was indicated as the
principal diagnosis on 61,709 inpatient
discharge records (
Table 4A-1).
However,
the E-codes for external
causes of injury were provided on a
substantially greater number of
inpatient discharges (
Figure 4D-1
,
Table 4D-1
).
Complications of medical
care and adverse effects of medical
treatment
(including adverse drug
reactions and complications from
surgical and medical procedures)
accounted for the absolute majority of
inpatient hospitalizations by the intent
of injury (57.1 percent).
Unintentional
injuries in accidents
accounted for 36.9
percent of all inpatient discharges by
intent of injury.
Self-inflicted injuries in
suicide
resulted in 4,374 inpatient
hospitalizations (3.0 percent).
Assault
accounted
for
2,830
inpatient
hospitalizations (1.9 percent of all
hospital discharges with known intent
of injury).

Percent Distributionof EmergencyRoomVisits by Intent of
Injury, ArizonaResidents, 2013
In 2013, there were 482,502
emergency room visits with known
intent of injury among Arizona
residents, 3 times as many as inpatient
discharges.
Unintentional injuries or
accidents
accounted for nine out of ten
(421,363 or 87.3 percent) of all injury-
related emergency room visits (
Figure
4D-3, Table 4D-2
). The external
cause of injury was classified as
assault
for 19,239 emergency room visits:
these were the injuries purposely
inflicted
by
another
person.
Complications of care
and
adverse
effects of medical treatment
accounted
for a greater number of emergency
room visits than
self-inflicted injuries in
suicide
(6.5 percent vs. 1.6 percent,
respectively,
Figure 4D-3, Table 4D-
2
).
