  • a RPh, pharmacist; LOS, length of stay.

  • b For AKIN group, n = 26; for NT group, n = 17. Where not otherwise defined, parenthetical values are percentages. *, P value < 0.05, chi-square or Fisher's exact test; Y, P value < 0.05, Wilcoxon-Mann-Whitney test.

  • c NT patients met both AKIN and NT criteria.
