Author Information
Author(s): Gregory J. Locksmith, Patrick Duff
Primary Institution: University of Florida
Hypothesis
The study aimed to determine the usefulness of blood cultures in evaluating patients with chorioamnionitis treated with a specific antibiotic protocol.
Conclusion
Routine blood cultures rarely provide information that justifies a change in clinical management for patients with chorioamnionitis treated according to the outlined antibiotic protocol.
Supporting Evidence
- Only one patient had a blood culture result that definitively altered therapy.
- 39 out of 538 patients had positive blood cultures, indicating a 7.2% bacteremia rate.
- The mean duration of febrile morbidity was similar in bacteremic and nonbacteremic patients.
Takeaway
The study found that taking blood cultures for patients with chorioamnionitis usually doesn't help doctors make better treatment decisions.
Methodology
The study reviewed medical records of patients with chorioamnionitis who delivered at the facility over a three-year period, analyzing blood culture results and their impact on treatment.
Limitations
The study did not include immunocompromised patients or those with underlying cardiac disease, which may limit the generalizability of the findings.
Participant Demographics
Patients with chorioamnionitis who delivered at the facility from July 1, 1989, to June 30, 1992.
