Review definitions, conceptual models, and error taxonomies. Overview study designs for diagnostic safety and quality research.


This section provides a listing of different definitions of errors and different ways to categorize the errors. We will also describe several of the types of studies that evaluate diagnostic error.

Conceptual Models & Definitions View

  • Conceptual models
  • Glossary of Definitions

Error Taxonomies View

To better understand and measure diagnostic errors, we must develop organized systems to collate and categorize them. Several error taxonomies have been suggested for this purpose and are briefly described below.

  • By outcome severity
  • By cause
  • By location in process
  • By clinical context

Overview of Data Sources View

  • Records of clinical encounters
  • Autopsies
  • Voluntary reports
  • Re-review of Source Data
  • Computerized screening algorithms
  • Surveys
  • Diagnostic testing audits
  • Standardized patients
  • Malpractice Claims, Risk Management and Safety Reports
