period, the number of tests ordered has increased dramatically. As a result, the cost of clinical laboratory testing has increased considerably [1]. This has prompted the introduction of research and initiatives aimed at controlling clinical laboratory utilization without affecting the continued improvement of the quality of patient care. The solutions that have been attempted with limited succ...

A number of techniques have been developed to effectively extract and generalize planning knowledge based on expert demonstration. In this paper we consider a complementary approach to learning in which we may execute experiments designed to test hypothesized planning knowledge. In particular, we describe an algorithm that automatically generates experiments to test assertions about plan-step o...

Visualization of multidimensional dataset is a challenging task due to non-uniformity of the data. It requires new ways to display data for better analysis and interpretation. Parallel coordinate is one of the popular techniques for visualization of multi dimensional dataset. Parallel coordinate technique emphasis various types of patterns present in the dataset. Here, pattern is shown by a pol...

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 orderin...

DNA microarrays technology can be used to discover the expression of thousands of genes and the regulatory relationship between them. This article presents an ordering method to analyze gene expression dynamics, and find the ordering relationship, such as the upstream or downstream between these genes. Our ordering method has two components: we use an ordering index (OI) combined with standard ...

Policy-based incentives for health care providers to adopt health information technology are predicated on the assumption that, among other things, electronic access to patient test results and medical records will reduce diagnostic testing and save money. To test the generalizability of findings that support this assumption, we analyzed the records of 28,741 patient visits to a nationally repr...

OBJECTIVES To evaluate the effectiveness of behaviour changing interventions targeting ordering of thyroid function tests. DESIGN Systematic review. DATA SOURCES MEDLINE, EMBASE and the Cochrane Database up to May 2015. ELIGIBILITY CRITERIA FOR SELECTING STUDIES We included studies evaluating the effectiveness of behaviour change interventions aiming to reduce ordering of thyroid function...
