3. RESULTS
A total of 173 patients with a
mean age of 47.6 ± 16.4 years were included in the study. Of the
patients, 57.8% (n=100) were male and 49.2% (n=73) were female. The
demographic and clinical characteristics of the patients are given in
Table 1. The source of infection was detected in the thoracic and
abdominal CT scans of 31.2% (n=54) of the patients. Gender, diastolic
blood pressure, respiratory rate, and body temperature did not
statistically significantly differ between the patients with and without
an infection source detected on CT. There was also no significant
difference between these two groups in relation to the white blood cell
(WBC) and C-reactive protein (CRP) levels (Table 2). Of the patients,
41% (n=71) had one or more comorbidities. In the single logistic
regression analysis, age, systolic blood pressure, heart rate,
procalcitonin (PCT), and presence of comorbidity were evaluated as risk
factors for the presence of infection in the thoracic and abdominal CT
scans. According to the multiple logistic regression analysis, age ≥ 65
years [odds ratio (OR):2.72, 95% confidence interval (CI):1.15-4.35,
p<0.001), presence of comorbidity (OR:2.37, 95% CI:1.08-4.14,
p=0.033), and PCT positivity (OR:2.54, 95% CI:1.29-4.95, p=0.006) were
determined as risk factors for the presence of infection in CT (Table
3).
