Bacteremia is a common clinical condition with an incidence of approximately 140 to 160 per 100,000 person-years. Since sepsis is a time-critical diagnosis, identification of emergency department (ED) patients at risk of bacteremia is therefore a priority. The study objective was to validate a previously published clinical decision rule for predicting a positive blood culture in ED patients with suspected infection based on minor criteria, major criteria and a total score .
Minor criteria (1 point each)
Suspected endocarditis (3 points)
Age >65 years
Temperature >39.4°C (103.0°F) (3 points)
Temperature 38.3 to 39.3°C
Indwelling vascular catheter (2 points)
Hypotension (systolic blood pressure <90 mmHg)
White blood cell count >18,000 cells/mm3
Bands >5% (in our setting, immature cells >0.5%)
Platelets <150,000 cells/mm3
Creatinine >2.0 mg/dl (177 µl/l)
The clinical decision rule performed well in our ED setting and is likely to be a useful supplement to clinical judgment.
