The National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) is a standardized system to quantify or grade the severity of adverse events (AE) that occur with drug treatment or from medical devices. A definition of mild (grade 1), moderate (2), severe (3), life-threatening (4) and death related to AE (5) events is provided for each AE term. The CTCAE v4.02 was published by NCI on October 6, 2009, and is used by many healthcare providers and researchers to characterize adverse events consistently. The Center for Biomedical Informatics (CBMi) at The Children's Hospital of Philadelphia has converted the 190+ pages of the CTCAE v4.02 document into an intuitive iPhone application. With this application, healthcare providers can reference the full CTCAE v4.02 with an iPhone or iPod Touch, allowing for bedside grading at the time of a visit and generally allowing the information to be accessed from anywhere at any time. The application contains all published grading standards for all 26 categories of adverse events as well as event definitions. The application also offers a variety of advantages over the flat file CTCAE v4.02, including: * Hierarchical navigation of adverse event categories * Ability to bookmark adverse events and categories to quickly access frequently graded events * Search for events across names, definitions and grades This application is one example of the many ways in which CBMi helps transform clinical care and research at our institution and across the industry.
