¹ Analysis of medication orders for vancomycin and aminoglycosides.

^∗ Variance F test used to detect a difference between standard deviations.

^† Renal insufficiency defined as creatinine clearance ²⁹ less than 40 milliliters/minute/1.73 m² (n = 32 for study, n = 18 for control) and adjustment made for total daily dose of aminoglycoside or vancomycin.
