Analysis of search in an online clinical laboratory manual.

Online laboratory manuals have developed into an important gateway to the laboratory. Clinicians increasingly expect up-to-date laboratory test information to be readily available online. During the past decade, sophisticated Internet search technology has developed, permitting rapid and accurate retrieval of a wide variety of content. We studied the role of search in an online laboratory manual. We surveyed the utilization of search technology in publicly available online manuals and examined how users interact with the search feature of a laboratory handbook. We show how a laboratory can improve its online handbook through insights gained by collecting information about each user's activity. We also discuss future applications for search-related technologies and the potential role of the online laboratory manual as the primary laboratory information portal.

Analysis of laboratory critical value reporting at a large academic medical center.

Reporting of laboratory critical values has become an issue of national attention as illustrated by recent guidelines described in the National Patient Safety Goals of the Joint Commission on Accreditation of Healthcare Organizations. Herein, we report the results of an analysis of 37,503 consecutive laboratory critical values at our institution, a large urban academic medical center. We evaluated critical value reporting by test, laboratory specialty, patient type, clinical care area, time of day, and critical value limits. Factors leading to delays in critical value reporting are identified, and we describe approaches to improving this important operational and patient safety issue.

High-resolution reference ranges for estradiol, luteinizing hormone, and follicle-stimulating hormone in men and women using the AxSYM assay system.

OBJECTIVES: High-resolution reference ranges are essential for reproductive hormones due to the significant day-to-day variation seen with these analytes. DESIGN AND METHODS: The performance of AxSYM assays for estradiol, luteinizing hormone (LH), and follicle-stimulating hormone was evaluated. RESULTS: These studies validate the performance of each assay, permitting high-resolution reference ranges to be established. CONCLUSIONS: The high-resolution reference range data provided herein for both normally cycling females and males should be applicable to a wide variety of clinical situations.

Physician survey of a laboratory medicine interpretive service and evaluation of the influence of interpretations on laboratory test ordering.

CONTEXT: Complex coagulation test panels ordered by clinicians are typically reported to clinicians without a patient-specific interpretive paragraph. OBJECTIVES: To survey clinicians regarding pathologist-generated interpretations of complex laboratory testing panels and to assess the ability of the interpretations to educate test orderers. DESIGN: Surveys were conducted of physicians ordering complex coagulation laboratory testing that included narrative interpretation. Evaluation of order requisitions was performed to assess the interpretation's influence on ordering practices. SETTING: Physicians ordering coagulation testing at a large academic medical center hospital in Boston, Mass, and physicians from outside hospitals using the academic medical center as a reference laboratory for coagulation testing. OUTCOME MEASURES: Physician surveys and evaluation of laboratory requisition slips. RESULTS: In nearly 80% of responses, the ordering clinicians perceived that the interpretive comments saved them time and improved the diagnostic process. Moreover, the interpretations were perceived by ordering clinicians to help prevent a misdiagnosis or otherwise impact the differential diagnosis in approximately 70% of responses. In addition, interpretations appeared to be able to train the ordering clinicians as to the standard ordering practices. CONCLUSIONS: The results demonstrate physician satisfaction with an innovative information delivery approach that provides laboratory diagnostic interpretation and test-ordering education to clinicians in the context of their daily workflow.

Laboratory testing for viral hepatitis.

Worldwide, infection with hepatitis viruses remains a major clinical and public heath concern. The laboratory is an integral part of the diagnosis of these infections since many of the manifestations are nonspecific, and the various hepatitis viruses show overlapping symptomatology. In this article, we discuss the laboratory diagnosis of viral hepatitis with special attention to the diagnostic approach for each of the major entities.
