UHCMC Adult IV Guidelines
Many resources available using the Internet
Should be utilized only if other databases or references fail to provide any valid information
Limitations include lack of quality control and imprecise searching that may lead to many undesired “ hits ”
Information found may not come from a verifiable source and potentially could be inaccurate, possibly leading to patient harm
If UHCMC has guidelines, protocols, or ordersets, use those developed by UHCMC staff
Variety of resources are available
Familiarize yourself with the on-line resources, databases, and textbook references in finding drug information
If all else fails, ask your pharmacist
