Mirex in the environment: its degradation to kepone and related compounds.

The chlorocarbon mirex undergoes slow, successive loss of chlorine in the field to a series of related compounds that had lost one or more chlorine atoms. Soil samples were recovered 12 years after treatment at 1 part per million (ppm), and ant bait was recovered 5 years after an aircraft crash. As much as 50 percent of the original mirex was recovered at levels of about 0.5 and 640 ppm, respectively. Kepone was present at levels of 0.02 ppm in soil and 10 ppm in the bait or up to 10 percent of the recovered mirex, as determined by combined techniques of chromatography and mass spectrometry. This constitutes the first observation of the degradation of mirex in nature, and demonstrates a pathway for its eventual disappearance from the environment.

Capital: the medical practice's life blood.

As physician organizations grow in size and stature, capital must be obtained for investment. One of the more common avenues is through either debt or equity. Some pros and cons of these sources are presented, along with some particular sources. In addition, examples of medical practices that have gone one route or the other are presented.

Point of care testing: regulation and accreditation.

OBJECTIVE: To provide an overview of point of care testing (POCT) regulatory and accrediting agencies and their requirements. DATA SOURCES: Current literature and the author's experience. DATA SYNTHESIS: To develop and successfully run a POCT program that meets the federally mandated standards evaluated by accrediting agencies with Health Care Financing Administration (HCFA) status, requires that participants are aware of CLIA '88 requirements. Joint Commission on Accreditation of Healthcare Organizations (JCAHO), College of American Pathologists (CAP) and Commission on Office Laboratory Accreditation (CQLA) are the 3 principal organizations currently inspecting and accrediting POCT programs. They have included all CLIA '88 requirements on their inspection checklists. This paper covers requirements of JCAHO and CAP. In order to successfully meet the accreditation requirements of HFCA and their deeming agencies, JCAHO and CAP, these issues must be addressed: direction and supervision of the program, procedures performed, proficiency testing, quality assurance, quality control, procedure manuals, specimen handling, results reporting, reagents, calibration and standards, instrument selection and maintenance, personnel training and competence, and safety. CONCLUSION: CLIA '88 states that all testing is site neutral, therefore the same regulations apply regardless of where the test is performed. All POCT programs must apply for a CLIA certificate and choose an appropriate accreditation agency for their needs. All accreditation agencies must follow the requirements listed in the federal register; some agencies are more stringent than others.
