Key Element

Latent Failures

Active Failures

 

warn that drug can be administered IM only.

  • Conflicting information about IV use of milky-white substances.

  • Lack of FDA requirement for “black box” or other vivid warning regarding IV administration of penicillin G benzathine in drug monographs.

 

Competency

  • Hospital had an unclear definition of prescriptive authority for nonphysicians.

  • Nurse practitioner assumed authority to change route of administration based on national protocol and current practice in hospital.

Labeling, Packing, and Nomenclature

  • Manufacturer’s warning for “IM use only” not prominently placed on syringe: syringe had to be rotated 180 degrees away from drug name to view the warning; plunger obscured the view after syringe prepared; “1,200,000” used instead of “1.2 million” units (errors occur when comma is misread).

  • Warning on syringe for “IM use only” not seen.

  • Ten-fold overdose not recognized.

  • Penicillin G benzathine administered intravenously.
