Hospital-related costs were compared based on time to initiation of fluconazole therapy and empirical fluconazole dose. Resource utilisation increased with inadequate fluconazole dosing in therapy.Total costs were lowest for patients started on fluconazole on the culture day with adequate doses ($35,45925,988) compared with all other patients ($52,15853,492) (P = 0.0088).Garey KW et al.Int J Antimicrob Agents. 2007;29(5):557-62.
