Abstract
Purpose: The purpose of this study was to determine if intravenous push (IVP) administration of piperacillin-tazobactam reduced the time to antibiotic administration compared to intravenous piggyback (IVPB) in emergency department (ED) patients who present with sepsis. Methods: This was a retrospective cohort study of patients with sepsis who received piperacillin-tazobactam before and after implementation of an IVPB to IVP conversion protocol. Results: A total of 486 charts were reviewed and the final analysis included 127 patients in each group. The mean time to administration of piperacillin-tazobactam was 67 (+/- 48) minutes and 58 (+/- 36) minutes in the IVPB and IVP cohorts, respectively (P = NS). The time to administration of secondary antibiotics was reduced by 38 minutes in patients who received piperacillin-tazobactam by IVP (105 min +/- 69 vs 67 min +/- 37; P < .001). Nurse administration time was reduced by 11 min for piperacillin-tazobactam (54 min +/- 46 vs 43 min +/- 33; P = .034) and 40 min for secondary antibiotics (90 min +/- 67 vs 50 min +/- 32; P = < .001) in the IVP group. There was no difference in hypersensitivity reactions, hospital length of stay, or mortality. Conclusion: Conversion from piperacillin-tazobactam IVPB to IVP was associated with a reduction in time to piperacillin-tazobactam and secondary antibiotic administration in emergency department patients with sepsis. Further prospective research is needed to evaluate clinical outcomes associated with IVP administration.
