The impact of direct inoculation of ascites into blood culture bottles on ascites culture positivity

摘要: ObjectiveAssess whether direct inoculation of ascites into blood culture bottles would improve ascites culture yield.DesignPre-post-study.SettingThe study was performed at a quaternary academic medical center in Houston, Texas, including all inpatient and emergency department encounters.PatientsAscites cultures collected from November 2020 to December 2022 were reviewed and screened for spontaneous bacterial peritonitis. Patients were excluded if a prior ascites culture from the same patient was already included in the study or if there was evidence of secondary bacterial peritonitis.InterventionIn the pre-intervention period, ascites cultures were collected into a sterile container and inoculated onto/into solid and liquid media. In the post-intervention period, ascites cultures were instead directly inoculated into bioMérieux© blood culture bottles at the bedside.Results114 patients met inclusion and exclusion …
