Databases: Accuracy and readiness for use

Abstract Decisions for improving health care rely on data often contained in databases. A database is a compilation of information, often a group of variables, that is stored electronically in a computerized system. It can be specific to one organization, a group of several facilities, or a nationwide effort. Databases comprise elements specific to the endeavour. Types of databases include clinical, administrative, research, or combinations of these. The purpose of electronic storage of specific data and the uses for the results of database analyses need consideration regarding accuracy, validity, and reliability. All databases are accurate to the extent that each element and each point of data collection and entry are valid and reliable. The purposes of this paper are to explore methods for determining accuracy of the data in a database, reliability and validity of database elements, and to determine when a database is ready for use.
