A rigorous evaluation process of diagnostic tests before introduction into clinical practice could:
• Reduce the number of unwanted clinical consequences related to misleading estimates of test accuracy [1] • Limit health care costs by preventing unnecessary testing [1] [1] (Bossuyt PM, Reitsma JB, Bruns DE, Gatsonis CA, Glasziou PP, Irwig LM, Lijmer JG, Moher D, Rennie D, de Vet HC:

accuracy
refers to the amount of agreement between the information from the test under evaluation and the reference standard.
[1] • Diagnostic accuracy can be estimated in several ways: sensitivity, specificity, receiver operating characteristic curves (ROC), positive and negative predictive values, likelihood ratios, and diagnostic odd ratios.
[2] • Several meta-analysis studies have emphasized the poor quality of research reports.

Aim
• Evaluate the quality of reporting of all diagnostic studies in infectious diseases literature between 1999 and 2005 using the Standards for Reporting of Diagnostic Accuracy (STARD) initiative parameters.
• Compare the studies of diagnostic accuracy in infectious diseases literature based on STARD statement (2003)" Nov 23, 2006 1st presentation 6

STARD
• To improve the quality of reporting of diagnostic accuracy studies the Standards for Reporting of Diagnostic Accuracy (STARD) was published. [1] • The STARD project group developed a checklist of 25 items and a prototypical flow chart to represent the design of the study and the flow of patients through the study.

Research Strategy
Bibliographic data base: MEDLINE
Journal selection based on
: • A table regarding the “Top 50 Journals That Frequently Publish Articles on Diagnostic Accuracy – 8 journals [4] • The impact factor of journals on infectious diseases retrieved “ISI Web of Knowledge” (2005) – 5 journals
13 journals
with impact factor greater than 5 were selected • [4] (Smidt N, Rutjes AWS, Van der Windt AWM, Ostelo RWJG, Reitsma JB, Bossuyt PM, Bouter LM, De Vet HCW:
