Summary

The revised gentamicin dosing guideline successfully improved therapeutic peak levels in newborns. This new guideline ensures safe and effective gentamicin use without routinely monitoring peak levels.

Area of Science:

  • Neonatal pharmacology
  • Antibiotic stewardship
  • Clinical auditing

Background:

  • Gentamicin is a critical antibiotic for neonatal infections.
  • Concerns existed regarding sub-therapeutic peak gentamicin levels with the previous guideline.
  • Optimizing gentamicin dosing is essential for efficacy and safety.

Purpose of the Study:

  • To audit existing gentamicin usage guidelines.
  • To develop and implement a new gentamicin dosing protocol.
  • To re-audit gentamicin levels following the guideline change.

Main Methods:

  • Prospective audit of gentamicin levels (trough and peak) under the old regime.
  • Implementation of a new gentamicin dosing regime.
  • Re-audit of trough levels and a subset of peak levels under the new regime.

Main Results:

  • The old regime had 92% sub-therapeutic peak levels.
  • The new regime achieved satisfactory trough levels in 96.6% of neonates.
  • 80% of peak levels were satisfactory under the new regime, with routine monitoring potentially reduced.

Conclusions:

  • The new gentamicin guideline effectively achieves therapeutic peak levels.
  • The revised protocol does not increase the risk of toxic trough levels.
  • Routine peak level monitoring may not be necessary for all neonates on the new regimen.
