Uniform basic data sets for health statistical systems

The United States approach to coordinating health statistics involves introduction of multipurpose basic data sets describing health status and the health care system. Standard reporting procedures have been used for many years for vital statistics. Recently designated data sets cover health manpower, inpatient facilities, short-stay hospital discharges, and use of ambulatory care services. A data set for long-term health care is in the design stage. Advantages of this approach in the United States and internationally are: basic comparisons can be made between health care settings are geographic areas while maintaining the variety and flexibility of existing public and private information systems; shared local, regional, and national data systems can be set up; and better coordination can be achieved between government-sponsored general-purpose and administrative data systems. Problem areas are: avoiding undue proliferation, e.g. of disease-specific data sets; adhering to the principle of minimal requirements; linking data sets and coordinating them with census and other social indicators; promoting widespread use; assuring data quality; establishing mechanisms for review and revision; and extending the concept internationally.
