The FilmArray Meningitis/Encephalitis (FA/ME) panel has acceptable-to-high sensitivities and high specificities for identifying bacteria, especially Streptococcus pneumoniae, and viruses, especially herpes simplex virus-2 (HSV-2) and enteroviruses, in patients with suspected central nervous system infection.
Background The FilmArray Meningitis/Encephalitis(FA/ME) panel brings benefits in clinical practice, but its diagnostic test accuracy (DTA) remains unclear. We aimed to determine the DTA of FA/ME for the aetiological diagnostic in patients with suspected central nervous system(CNS) infection. Methods We performed a systematic review with DTA meta-analysis (PROSPERO: CRD42020139285). We searched Embase, Medline (Ovid), and Web of Science from inception until September 1st, 2021. We assessed the study-level risk of bias with the QUADAS-2 tool and applied the GRADE approach to assess the certainty of the synthesised evidence. We included studies that simultaneously measured the reference test (CSF/blood culture for bacteria, and specific polymerase chain reaction for viruses) and the FA/ME in patients with suspected CNS infection. We performed random-effects bivariate meta-analysis models of combined sensitivity and specificity using CSF/blood cultures (reference test 1) and a final diagnosis adjudication based on clinical/laboratory criteria (reference test 2). Findings We included 19 studies (11,351 participants). For all bacteria with reference test 1 (16 studies/6183 patients) sensitivity was estimated at 89.5% (95%CI 81.1-94.4), and specificity at 97.4% (95%CI 94-98.9). With reference test 2 (15 studies/5,524 patients), sensitivity was estimated at 92.1%(95%CI 86.8-95.3) and specificity at 99.2 (95%CI 98.3-99.6) For herpes simplex virus-2(HSV-2), enteroviruses, and Varicella-Zoster virus (VZV), we obtained sensitivities between 75.5 and 93.8%, and specificities above 99% (reference test 1). Certainty of the evidence was low. Interpretation FA/ME may have acceptable-to-high sensitivities and high specificities for identifying bacteria, especially for S.pneumoniae, and viruses, especially for HSV-2, and enteroviruses. Sensitivities for L.monocytogenes, H. influenzae, E.coli, and HSV-1 were suboptimal. Copyright (C) 2022 Published by Elsevier Ltd.
