The patient was admitted to the ICU with orders for new blood cultures, urine cultures, T2Bacteria Panel, and was started on empiric antibiotics, IV fluids, and vasopressors.
Patient Selection Criteria
A patient suspected of sepsis with other microbiological evidence of infection
Evaluation and Treatment Decision
Septic Shock (unknown origin of infection)
Ampicillin/sulbactam and tedizolid
Positive for P. aeruginosa
Blood Culture Result
Decision making based on T2Bacteria Result
A rapid T2Bacteria result allowed for the identification of the P. aeruginosa bacteremia in a patient with septic shock and blood culture-negative infection. This result prompted the prescriber to escalate therapy to ceftolozane/tazobactam and amikacin.
