"ABSTRACT

PURPOSE In this study, we assessed whether multivariate models and clinical
decision rules can be used to reliably diagnose influenza.
METHODS We conducted a systematic review of MEDLINE, bibliographies of relevant
studies, and previous meta-analyses. We searched the literature (1962-2010)
for articles evaluating the accuracy of multivariate models, clinical decision rules, or simple heuristics for the diagnosis of infl uenza. Each author independently reviewed and abstracted data from each article; discrepancies were resolved by consensus discussion. Where possible, we calculated sensitivity, specifi city, predictive value, likelihood ratios, and areas under the receiver operating characteristic curve. RESULTS A total of 12 studies met our inclusion criteria. No study prospectively validated a multivariate model or clinical decision rule, and no study performed a split-sample or bootstrap validation of such a model. Simple heuristics such as the so-called fever and cough rule and the fever, cough, and acute onset rule were each evaluated by several studies in populations of adults and children.
The areas under the receiver operating characteristic curves were 0.70 and 0.79,
respectively. We could not calculate a single summary estimate, however, as the
diagnostic threshold varied among studies.
CONCLUSIONS The fever and cough, and the fever, cough, and acute onset heuristics
have modest accuracy, but summary estimates could not be calculated.
Further research is needed to develop and prospectively validate clinical decision
rules to identify patients requiring testing, empiric treatment, or neither."
