ICD-9-CM diagnostic codes 300.4 and 311.
In 2013, the ICD-9-CM diagnostic codes
300.4 and 311 for depression were used
on 2,568 inpatient discharge and 6,885
emergency room records as the first-
listed diagnosis (for a total of 9,453
hospital encounters;
Figure 4A-5, Table
4A-1, Table7C-1
).
The extent to which the first-listed
diagnosis is the principal reason for
hospitalization ought not to be
overestimated. More often than not, the
first-listed diagnosis is the immediate, but
not necessarily the underlying cause of
hospitalization.
However, when we count all entries of
this code within the nine diagnostic fields,
depression was mentioned on 100,979
inpatient discharge and emergency room
records. In fact, the depression diagnosis
was substantially more frequently present
as 2
nd
? 7
th
listed on the medical record
than it was first-listed (
Figure4A-5
).
When hospital data is used to estimate
the prevalence of depression, it makes
sense to include all mentions of this
disorder in all diagnostic fields, not just
the first one.

Inpatient HospitalizationRates for Enterocolitis due to
Clostridiumdifficile
ByAgeGroup, ArizonaResidents, 2013
In 2013, 2,701 Arizonans were
hospitalized with the diagnosis of
enterocolitis due to
Clostridium difficile
, a
bacterial inflammation of the intestines
(
Table 4A-1
). The disease is of growing
public health concern because it is often
acquired in hospitals and other health
care institutions with long-term patients
as residents.
The inpatient hospitalization rates
associated with enterocolitis due to
Clostridium difficile
tend to increase with
age. The rate for the elderly 65 years or
older (16.0/10,000) was 3.8 times
greater than the rate of middle-aged
adults (
Figure4A-6
).
In 2013, 189 Arizonans died from
enterocolitis due to
Clostridium difficile.
Elderly 65 years or older accounted for
87.3 percent of these deaths (
Table 2C-
27
).
