BACKGROUND The performance of rapid influenza diagnostic tests (RIDTs) in detecting influenza A(H1N1) 2009 has varied widely. Evaluations of RIDTs among infected individuals across all age groups have not been described in depth. OBJECTIVES Determine RIDT clinical sensitivity in comparison with influenza detection using real-time RT-PCR among patients infected with influenza A(H1N1) 2009 acro...

This paper presents a procedure designed to aid physicians and patients in the process of making medical decisions, and illustrates its implementation to aid pregnant women, who decided to undergo prenatal diagnostic test choose a physician to administer it. The procedure is based on a medical decision-making model of Karni (J Risk Uncertain 39: 1–16, 2009). This model accommodates the possibil...

We have constructed a Bayesian influence diagram and implemented an analytic framework to recommend strategies for selecting prenatal diagnostic tests and deciding whether to terminate a pregnancy based on their results. Our model is an improvement over previous applications of decision analysis to prenatal testing because it includes multiple diseases (Down’s syndrome, neural-tube defects, cys...

A prescriptive model approach in decision making could help achieve better diagnostic accuracy in clinical practice through methods that are less reliant on probabilistic assessments. Various prescriptive measures aimed at regulating factors that influence heuristics and clinical reasoning could support clinical decision-making process. Clinicians could avoid time-consuming decision-making meth...

OBJECTIVE To quantify non-compliance of diagnostic practice with recommendations in Diagnostic Imaging Pathways and the impact of interventions to reduce non-compliance. DESIGN Retrospective audits, followed by intervention and re-audits. SETTING Emergency department (ED) of Royal Perth Hospital. PARTICIPANTS Six hundred and thirty-eight patients (first audit) and 423 patients (second aud...

various scoring systems have been devised to aid diagnosis of acute appendicitis. the main objective of this study was finding the accuracy of modified alvarado score in prediction of acute appendicitis. the registries of cases with appendectomy, who had been admitted to a referral medical center in the capital of iran from february 2000 to march 2004, were studied. sensitivity and specificity ...

OBJECTIVE This study examines how characteristics of clinical cases and physician users relate to the users' perceptions of the usefulness of the Quick Medical Reference (QMR) and their confidence in their diagnoses when supported by the decision support system. METHODS A national sample (N = 108) of 67 internists, 35 family physicians, and 6 other U.S. physicians used QMR to assist in the di...

Introduction Intelligent Diagnostic Assistant can be used for complicated diagnosis of skin diseases, which are among the most common causes of disability. The aim of this study was to design and implement a computerized intelligent diagnostic assistant for complicated skin diseases through C5's Algorithm. Method An applied-developmental study was done in 2015. Knowledge base was developed ba...

OBJECTIVES To investigate the reliability of CT-angiography of the lower extremities (run-off CTA) to derive a treatment decision in patients with acute and chronic peripheral artery disease (PAD). MATERIALS AND METHODS 314 patients referred for run-off CTA were includ-ed in this retrospective study. First, diagnostic confidence of run-off CTA to derive a treat-ment decision was assessed in a...
