One Size Fits All? Application of Susceptible-Dose-Dependent Breakpoints to Pediatric Patients and Laboratory Reporting.

The Clinical and Laboratory Standards Institute antimicrobial and antifungal standards define a susceptible-dose-dependent (SDD) category for certain organisms and drug combinations. Reporting MICs within the SDD category suggests that treatment success is likely with increased drug exposure. These breakpoints are based on pharmacokinetic, pharmacodynamic, and clinical outcome data from adults and not pediatric patients.

In Vitro Activity of Ceftolozane/Tazobactam vs Nonfermenting, Gram-Negative Cystic Fibrosis Isolates.

Ceftolozane/tazobactam (C/T) was tested and compared against 93 nonfermenting, Gram-negative clinical isolates from cystic fibrosis specimens. Based on current breakpoints for intra-abdominal and urinary tract infections (which may not be appropriate for pulmonary infections), C/T was found to be the most active agent against (95.7% susceptible), followed by piperacillin/tazobactam (89.

Accuracy of pharmacy benefit manager medication formularies in an electronic health record system and the Epocrates mobile application.

Background: Physicians commonly use formulary medication coverage information generated by electronic heath records (EHRs) and the Epocrates mobile drug database application when making medication selection decisions. Nonformulary selections may lead to higher out-of-pocket patient costs and nonadherence with prescribed regimens. Nonformulary selections also contribute to higher overall health plan spending.
