“…EQA programs were first introduced in the United States in 1935 when the U.S. Department of Public Health offered a program for syphilis testing. 2 The College of American Pathologists offered the first U.S. program addressing coagulation in 1960 and reported in 1963. 3 The development of that program is detailed in another article in this issue.…”

External Quality Assurance in Thrombosis and Hemostasis (EQATH) was organized in 2005 as an international collaboration of external quality assurance (EQA) programs and organizations with a common interest in improving the quality of hemostasis testing. The goals include exchanging of information regarding program operations; exchanging split specimens among programs to determine if there are differences in practice; participating in value setting of standards; and providing outreach programs to locations in the world without EQA support of hemostasis testing in laboratories. The organization currently includes 11 EQA programs from 10 countries. A survey of program structure and function revealed variation in the size and structure among the programs. In general, the staffing levels paralleled the size and complexity of the program. The number of laboratory participants in the EQA programs ranged from 58 to 1700. The presentation of testing covered in the program (modules) ranged from a program with a single module of a single test, to programs with single modules of many different types of tests, to a program with 13 modules, each of which contains a limited scope of related tests. Participating laboratories were graded (pass/fail or out with consensus) by six of the EQA programs, whereas five programs report the results to the laboratory for self-evaluation. Of the 11 programs responding, seven have deemed status from an accrediting or licensing agency, and successful participation satisfied requirements for accreditation for the participating laboratory. This type of benchmarking activity and cooperative activity among EQA programs will lead to improvement of the programs.

“…In the 1930s, 9 the need for interlaboratory standardization for public health programs led to early efforts at EQA. The concept of an unknown specimen being sent from a central EQA agency to the laboratory for testing with the results sent back to the agency for evaluation added an important new level of assurance for the quality of analysis.…”

So", you might ask, "What is quality, anyway?" The word quality repeatedly infi ltrates our discussions and interactions as we work to produce or choose a product. The Oxford English Dictionary devotes more that 3000 words in its effort to defi ne the many variations on the use of this word. We may all have diffi culty with a defi nition, but we do know what we mean. The customer of the product or service defi nes many aspects of its quality while those who are producing defi ne many others. Stated in its simplest terms, quality is the condition or state of a person, thing or process.Elements of quality management systems began with a publication by Shewhart in 1931 1 providing a footing for quality processes based on a scientifi c and/or statistical footing. He stated: "A phenomenon will be said to be controlled when, through the use of past experience, we can predict, at least within limits, how the phenomenon may be expected to vary in the future. Here it is understood that prediction means that we can state, at least approximately, the probability that the observed phenomenon will fall within given limits." 1 The evolution of quality management systems were infl uenced by experiences in World War II. During the war, individuals involved in the production of reliable devices (weapons and other implements to support a war effort) for the consumer (soldier) to do their job effectively tied the entire system from raw

“…Evaluation studies of serologic tests for syphilis have been conducted in the United States by the Public Health Service since 1935. The first Public Health Service evaluation study (1) was made to determine the reliability of several serologic tests for syphilis then in use in this country. All authors of tests or those who had modi¬ fied preexisting procedures were invited to par¬ ticipate.…”
