Another external response to concerns about MCOs has been an increased interest in measuring the quality of care they deliver [35]. This interest has resulted in the development of numerous quality indicators. One example, HEDIS (Health Plan Employer Data and Information Set), is a standardized set of performance indicators used to compare health plans. Developed by the National Committee for Quality Assurance, HEDIS measures allow employers and employees to evaluate different plans. Only a small number of HEDIS indicators are related to medication use, but more drug-related indicators are likely to be added in the future. The use of quality indicators likely will increase as the measures become more refined and tested.

Procedures should be organized and indexed in the form of manuals and must be written in compliance with National Committee for Clinical Laboratory Standards (NCCLS) GP2-A2 (3). Technical procedures designed for use at the bench should be complete, easy to follow, and readily available to testing personnel. These procedures must contain the following information for each assay performed ... 

The study was performed in patients exposed to ionizing radiation after Chernobyl accident. Comparison groups included patients and healthy individuals exposed to the natural radiation levels. Control group included healthy volunteers who resided in Kyiv since Chernobyl accident Distribution by diagnosis is presented at table 1. Investigated persons were at the age of 43-72 (mean+SD for the exposed group 52,3 + 10,1 yrs for control group- 46,3 + 11,3 yrs). All studied persons participated by informed consent. Peripheral blood and bone marrow samples were obtained by a standard procedure (National. Committee for Clinical Laboratory Standards, 1991). Flow...

Scientists at the National Laboratories of the National Committee for Nuclear Energy (C.N.E.N.) at Frascati, Italy pioneered the first electron-positron ring in 1959. Each beam of the machine was 0.25 GeV and yielded a center-of-mass energy of 0.5 GeV. This ring was lata moved to the Orsay laboratory outside Paris, France. The number of such rings grew quite rapidly.

The National Committee for Sugar Analysis, through the activities of its subcommittee on color evaluation, has recommended the above definitions of absorbancy and attenuancy. General adoption of these terms by the sugar industry would be a contribution to uniform reporting of their results. 

The degree of resistance of the mutant clones to the relevant PRP may be assayed by a number of methods. The broth microdiluition susceptibility test, a reference method for determination of the Minimum Inhibitory Concentration (MIC), may be performed according to the guidelines of the National Committee for Clinical Laboratory Standard (NCCLS) as described (20). An example of the increase in the MIC values for Bac7(l-35) in mutagenized HB101 is shown in Table 1. Another suitable and simple method, here described, is the count of bacterial viable cells after incubation with the peptide. 

Standardized methods for surveillance of antifungal drug susceptibility have been a recent development (Rex et al, 1993). The M27 protocol of the National Committee for Clinical Laboratory Standards (NCCLS) for testing of yeasts focused on laboratory to laboratory reproducibility and became an approved standard in 1997 (National Committee for Clinical Laboratory Standards, 1997). A modification of M27 for testing of molds has recently been proposed as NCCLS document M38-P (National Committee for Clinical Laboratory Standards, 1998). With these tools, collaborative studies to validate the predictive power of these results have been possible. Interpretive breakpoints for... 

The hierarchy established among the different methods and materials suggests an easy organization (Tietz, 1979). However, serious practical problems have hampered fast progress. In the United States and in Europe, the National Committee for Clinical Laboratory Standards (NCCLS) and the European Committee for Clinical Laboratory Standards (ECCLS) have been founded. These standardization organizations promote the development and the ultimate use of reference materials and methods. The National Bureau of Standards (NBS) and the Centers for Disease Control (CDC) in the United States (Bayse, 1982), and the European Community Bureau of Beference (BCR) in Europe, undertake projects oriented more toward the preparation of certified reference materials (BCR, 1982).

To resolve such confusion, several professional organizations have recommended water quality standards that are graduated according to classes of use. These specifications enable users to define their needs with more precision. Typical are those of the ASTM, the National Committee for Clinical Laboratory Standards (NCCLS), the College of American Pathologists (CAP), and the American Chemical Society (ACS). These specifications are summarized in Table 6-6. In general, laboratory water quality is defined in terms of its resistivity. The historical focus on resistivity as a measure of water quality presupposes that dissolved minerals are the main concern. Often it is true, but resistivity has been used as the major yardstick for water purity mainly because it has been the most easily measured. 

In the course of the integration of European states and the removal of trade barriers, national standardization loses importance considerably. The majority of electrical standards comes into existence by international cooperation with IEC, International Electrotechnical Commission, Geneva/Switzerland. On the basis of IEC Standards many European Standards have been developed in the past. This work has been done by CENELEC, Comite Europeen de Normalisation Electrotechnique, Brussels/Belgium. European Standards or Norms (EN) often deviate from their IEC origins in their technical content. To avoid double action and to ensure a more effective standardization procedure, IEC and CENELEC are now working in closer cooperation. CENELEC is a private organization and does not act as an institution of the European Union at all. This fact indicates that European Standards need a legal act to come into force. Members of CENELEC are the national committees for standardization of the member states (not identical with the European Union).
