Multicenter StudyBedside glucose monitoring quality control practices. A College of American Pathologists Q-Probes study of program quality control documentation, program characteristics, and accuracy performance in 544 institutions.
To investigate the adequacy of bedside glucose monitoring (BGM) quality control documentation and monitoring, characterize program structure and organization, and identify characteristics associated with the ability to produce accurate results. ⋯ There is a need for improving compliance with QC documentation, improving appropriate corrective action follow-through, decreasing the frequency of inappropriate patient testing, and improving BGM accuracy performance. We provide recommendations for improvement.

Histologic, microbiologic, and clinical correlates of the diagnosis of sarcoidosis by transbronchial biopsy.
To determine the frequency of positive microbiologic cultures in patients with epithelioid granulomas and negative histochemical stains for microorganisms in transbronchial biopsy specimens. Secondary objectives were to compare the histologic features of sarcoidosis with those of infectious granulomas and to assess the reliability of histology in establishing the diagnosis of sarcoidosis. ⋯ Numerous granulomas, Schaumann bodies, and a high clinical probability of sarcoidosis are significantly associated with that diagnosis. Necrosis does not exclude sarcoidosis. Clinicopathologic assessment of transbronchial biopsy specimens is useful in predicting the final diagnosis of sarcoidosis but does not obviate the need for microbiologic cultures, which were positive in 10.9% of patients in this study.
