Abstract [en]

Background: After medical center implementation of 2009 ASHP/IDSA guidelines, we evaluated the appropriateness of vancomycin dosing and TDM.

Objective: Our primary objectives were to assess short term effects on (1) appropriateness of initial vancomycin dosing, (2) appropriateness of sampling of plasma levels, before and after implementation of guidelines.

Method: The study was conducted in two phases, pre-guideline and post-guideline implementation. The interventions included (1) Nurses and phlebotomist education regarding the appropriate timing of vancomycin sampling, (2) A nomogram for appropriate initial dosing that was distributed to medical staff. Patient demographics, dosing and timing of sampling were collected in eligible patients and assessed for appropriateness.

Results: The appropriateness of the prescribed dose increased from 51% (128/253) of patients during the pre period to 78% (155/200) (p < 0.0001) during the post period. Similarly, overall appropriateness of sampling of vancomycin troughs at steady state improved from 36% (63/173) pre to 55% (106/191) (p < 0.03) post. Specifically, the appropriate timing of troughs (within 30 min of the next dose) increased from 37% (64/173) during the pre period to 78% (149/191) during the post period (p < 0.0001).

Conclusion: Adoption of the guidelines with associated training resulted in significant short term improvement in vancomycin dosing and TDM.
