RESULTS
Of 370 patients who were eligible, 26 had UTI on
admission and were excluded from analysis, so 344
patients were analysed. Background characteristics of
patients are illustrated in Table 1.
The mean age of analysed cases was 65·16 ±
20·85 years and the median was 71 years. As far as
the reasons for catheterization are concerned, only
33·3% of them were fully justifiable.
Incidence of CAUTI in 344 patients studied was
21·8% (32·7/1000 catheter–days). Incidence of CAUTI
by type of organism is demonstrated in Table 2. Gramnegative
bacilli other than pseudomonas were the
cause in 39·2% of CAUTI episodes, and Gram-positive
cocci other than enterococci were seen in 20·2% of
cases.
Pyuria was detected in 64·8 and 33·6% of the
patients with and without UTI, respectively (P = 0·00).
The mean age of those infected versus non-infected
was 67 vs. 64·2 years (P = O·4). The incidence of
CAUTI by risk factors is shown in Table 3. Age greater
than 65 years old, duration of catheterization longer
than 7 d, and length of hospital stay longer than 8 d were associated with higher rate of infection
and receiving antimicrobial while catheter in situ was protective. Table 4 presents the impact of each risk factor
on acquiring UTIs after backward logistic regression
showing that from three risk factors maintained in the
model, only duration of catheterization longer than 7
d was important in acquiring infection and receiving
antimicrobial was protective. Device utilization rate
was 0·84.
