The National Practitioner Data Bank's Public Use Data File is now updated to contain information from disclosable reports received from September 1, 1990 through December 31, 2007. The data file does not include information identifying individual practitioners or reporting entities and is designed for statistical analysis. It does includes selected variables from adverse actions against physicians, dentists, and other licensed health care professionals. Those required to report this data include malpractice payers, state licensing agencies, hospitals, other entities (including federal governmental), and professional societies.
