Dialog, a Thomson business and provider of online-based information services and integrated information solutions, has added three files of epidemiological data to its collection of medical information available through its Dialog online service. Dialog is used by medical researchers, biotech and pharmaceutical companies, government healthcare agencies, insurance forecasters, medical equipment manufacturers, consultants and others to conduct research and track trends on a range of health-related topics.
The three new files now available exclusively through the Dialog services are Hospital Inpatient Profiles (File 462), Hospital Outpatient Profiles (File 463), and Emergency Room (File 454). Each is composed of data compiled in the United States. The databases are provided by Timely Data Resources (www.tdrdata.com), based in Capitola, California, which also supplies Dialog with its Incidence and Prevalence database (File 465), also available exclusively through Dialog.
The Hospital Inpatient Profiles file provides data on more than 7,000 diseases afflicting U.S. hospital inpatients. It also includes data on procedures, related illnesses, payment source, discharge status, and more. The data originates from the annual National Hospital Discharge Survey, covering approximately 270,000 inpatient records from about 500 hospitals.
The Hospital Outpatient Profiles file provides data on more than 2,400 diseases inflicting outpatients surveyed as part of the annual National Hospital Ambulatory Medical Care Survey (NHAMCS), a national probability sample of hospital visits. The research is conducted by the National Center for Health Statistics, part of the U.S. federal government's Centers for Disease Control (CDC). Information available includes drugs prescribed, diagnostics provided, visit characteristics, payment source, disposition, and related data.
The Emergency Room file, also based on the CDC's NHAMCS research, covers 2,600 diseases. Data available includes the characteristics of patients arriving in emergency rooms (such as gender, ethnicity breakouts, and expected payment sources); characteristics of visits (such as urgency of care required, level of pain, and place of injury); and diagnostics, screening, medications and procedures provided.
