Key inclusion criteria

Gram positive bacteremia or Gram negative bacteremia detected by BacT/Alert 3D system (Sysmex bioMerieux Co., Ltd, Tokyo, Japan)

Key exclusion criteria

1)If only one set of blood cultures is positive among two sets of blood cultures incubated, and Staphylococcus spp. or Gram-positive rods are suspected by Gram stain examination.
2)If one set of blood culture is positive with Staphylococcus spp. suspected by Gram stain examination and contamination is clinically considered.
3)If blood cultures are positive and Gram-positive rods are suspected in nosocomial bacteremia patients.
4)If differentiation between Gram-positive and Gram-negative bacteria is difficult by Gram stain examination.
5)If more than two species of bacteria are suspected by Gram stain examination.
6)If more than 24 hours have passed after positive blood culture alarm by BacT/Alert 3D system.
7)If Gram stain examination of positive blood culture indicates the same bacteria as previous positive blood culture obtained within the past week.
8)If patients have already been referred or transferred to other hospitals.
9)If patients are not hospitalized in Tsukuba Medical Center Hospital.
10)If palliative care is performed without treatment for infections.
