Documenting resident procedure and diagnostic experience: simplifying the process.

BACKGROUND AND OBJECTIVES: The Residency Review Committee (RRC) requires documentation of family practice residents' procedural and diagnostic experiences. Further, hospital privileging is frequently based on documentation of prior clinical experience. Residency programs need a user-friendly (ie, resident-friendly) mechanism for collecting data and generating reports to document these experiences. This paper outlines a simplified, user-friendly method of documenting resident procedural and diagnostic experiences. METHODS: We developed a pocket-sized, optically scannable card for data input. This is coupled with a computerized database with report generation capability. The system is based on diagnostic clusters to further simplify the data input process. RESULTS: The system's setup costs are about $10,000. Annual maintenance and operational fees are about $5,000. After instituting the system, the number of residents submitting documentation information increased substantially. CONCLUSIONS: This system meets both RRC and potential clinical privileging requirements and provides a useful tool for guiding resident evaluation and developing appropriate training opportunities during the latter half of the residency. Simplified, accurate documentation may allow for comparisons among residents at various levels--program, state, and national.

The formation of a stable complex between dissociated proteoglycan and hyaluronic acid in the absence of a link protein.

A proteoglycan fraction prepared from bovine articular cartilage under dissociative conditions was shown to interact with three purified hyaluronic acid preparations to form stable complexes in the analytical ultracentrifuge. It is concluded from these experiments that, although link proteins are associated with hyaluronic acid and proteoglycans in complexes between these macromolecular constituents.

Scanning transmission electron microscope studies of deep-frozen unfixed muscle correlated with spatial localization of intracellular elements by fluorescent x-ray analysis.

Thin sections of deep-frozen unfixed muscle were studied in a scanning electron microscope modified for transmission imaging and equipped with a "cryostage" for vacuum compatibility of hydrated tissue. With an energy-dispersive x-ray analysis system, intracellular atomic species in the scan beam path were identified by their fluorescent x-rays and spatially localized in correlation with the electron optical image of the microstructure. Marked differences are noted between the ultrastructure of deep-frozen hydrated muscle and that of fixed dehydrated muscle. In frozen muscle, myofibrils appear to be composed of previously undescribed longitudinal structures between 400-1000 A wide ("macromyofilaments"). The usual myofilaments, mitochondria, and sarcoplasmic reticulum were not seen unless the tissue was "fixed" before examination. Fluorescent x-ray analysis of the spatial location of constituent elements clearly identified all elements heavier than Na. Intracellular Cl was relatively higher than expected.
