Arch Pathol Lab Med 129:1252-61. 2005..These databases include the CAP's Q-Probes and Q-Tracks programs, which provide information on error rates from more than 130 interlaboratory studies...- Audit of transfusion procedures in 660 hospitals. A College of American Pathologists Q-Probes study of patient identification and vital sign monitoring frequencies in 16494 transfusionsDavid A Novis
Department of Pathology, Wentworth Douglass Hospital, Dover, NH 03820, USA
Arch Pathol Lab Med 127:541-8. 2003..Hemolytic transfusion reactions are often the result of failure to follow established identification and monitoring procedures... - Q-tracks: a College of American Pathologists program of continuous laboratory monitoring and longitudinal trackingRichard J Zarbo

Arch Pathol Lab Med 126:809-15. 2002..Identification of patients is one of the first steps in ensuring the accuracy of laboratory results. In the United States, hospitalized patients wear wristbands to aid in their identification, but wristbands errors are frequently found... - Continuous monitoring of stat and routine outlier turnaround times: two College of American Pathologists Q-Tracks monitors in 291 hospitalsDavid A Novis
Department of Pathology, Wentworth Douglas Hospital, Dover, NH 03820, USA
Arch Pathol Lab Med 128:621-6. 2004..The laboratory test turnaround times (TATs) that exceed the expectations of clinicians who order those tests, the so-called outlier test reporting rates, may be responsible for perceptions of inadequate laboratory service... - Comparative analytical costs of central laboratory glucose and bedside glucose testing: a College of American Pathologists Q-Probes studyPeter J Howanitz
Department of Pathology, State University of New York, Downstate Medical Center, Brooklyn 11203 2098, USA
Arch Pathol Lab Med 128:739-45. 2004..Although fully automated central laboratory glucose testing and semiautomated bedside glucose testing (BGT) are performed at most institutions, rigorous determinations of interinstitutional comparative costs have not been performed... - Evaluation of total serum calcium critical valuesJoan H Howanitz
Department of Pathology, University Hospital of Brooklyn, Brooklyn, NY, USA
Arch Pathol Lab Med 130:828-30. 2006..Total serum calcium commonly is included in critical results lists; however, a wide range of values are used and there is scant outcome data justifying inclusion of this analyte in these lists... - Blood transfusions leading to apparent hemoglobin C, S, and O-Arab hemoglobinopathiesTzvetan B Kozarski
Department of Pathology, Box 25, State University of New York, Downstate Medical Center, 450 Clarkson Ave, Brooklyn, NY 11203, USA

Dept of Pathology, SUNY Downstate, New York, NY, USA
Am J Clin Pathol 127:56-9. 2007..The mortality rates of hyponatremic and hypernatremic inpatients were 19% and 48%, respectively. Disease severity as measured by length of stay and mortality indicated these critical limits should not be broadened... - Resident training in point-of-care testingSheldon Campbell
Department of Laboratory Medicine, Yale University School of Medicine, New Haven, CT 06520, USA
Clin Lab Med 27:397-410; abstract viii. 2007..Although the essential elements of quality testing are the same for laboratory-based and POCT, the enormous variety of settings, technologies, and workers involved present unique challenges...
