Bacteremia is the "presence of viable bacteria circulating in the blood. Fever, chills, tachycardia, and tachypnea are common acute manifestations of bacteremia. The majority of cases are seen in already hospitalized patients, most of whom have underlying diseases or procedures which render their bloodstreams susceptible to invasion."[1]
Diagnosis
| Finding | Sensitivity |
|---|---|
| Abnormal body temperature (<36.1°C (97°F) or >38°C (100.4°C) |
67% |
| Abnormal leukocyte count < 4 K/μL or > 10 K/μL |
48% |
| Abnormal bandemia > 5% total bands |
82% |
| Abnormal body temperature or leukocyte count | 83% |
A clinical prediction rule aids in identifying patients who might have positive blood cultures.[3]
A clinical prediction rule aids in identifying patients with bacteremia from staphylococcus aureus who might develop bacterial endocarditis.[4]
Alternative methods of collecting blood cultures have been suggested.[5]
