    Abstract:
    The prehospital environment has not been studied for point-of-care testing. Therefore, the authors' helicopter program evaluated the performance of the i-STAT Portable Clinical Analyzer, a rapid point-of-care, hand-held instrument. The primary aim of the study was to determine if the i-STAT Portable Clinical Analyzer could be used in the field to assess patient status in flight, and to allow the flight crew to intervene immediately, thus delivering a more stable patient to the emergency room. Imprecision and initial split-sample comparative studies with the Portable Clinical Analyzer were completed in the hospital satellite laboratory and clinical chemistry laboratory. Comparison studies were performed on patient samples drawn and analyzed in the helicopter and subsequently analyzed in the satellite and clinical chemistry laboratories. The only significant differences observed were with glucose. The glucose discrepancies were probably due to the time delay between collection of the specimen in the helicopter and subsequent analysis in the laboratory. Following this initial validation, the i-STAT Portable Clinical Analyzer was used on 81 patients transported by the flight crew. The tests performed in the helicopter include sodium, potassium, glucose, and hematocrit/hemoglobin concentrations. Fifteen (18.5%) of the patients were treated with transfusions, glucose, or insulin based on the Portable Clinical Analyzer results. Other identified needs include blood gas analysis (in process) and use of point-of-care testing in the fixed-wing environment.
