An electronic thesaurus of Evidence Based Laboratory Medicine hematological and biochemical diagnostic tests

Summary The adoption of Evidence Based Laboratory Medicine (EBLM) has been hampered until today by the lack of effective tools. The SIMeL EBLM e‐Thesaurus (on‐line Repertoire of the diagnostic effectiveness of the laboratory, radiology and cardiology test) provides a useful support to clinical laboratory professionals and to clinicians for the interpretation of the diagnostic tests. The e‐Thesaurus is an application developed using Microsoft® Active Server Pages technology and carried out with Web Server Microsoft® Internet Information Server and is available at the SIMeL website using a browser running JavaScript® scripts (Internet Explorer® is recommended). It contains a database (in Italian, English and Spanish) of the sensitivity and specificity (including the 95% confidence interval), the positive and negative likelihood ratios, the Diagnostic Odds Ratio and the Number Needed to Diagnose of more than 2000 diagnostic (most laboratory but also cardiology and radiology) tests. The e‐Thesaurus improves the previous SIMeL paper and CD Thesaurus; its main features are a three languages search and a continuous and an easy updating capability.
