Abstract

Meningitis and encephalitis (ME) are important causes of morbidity and mortality worldwide. Patients suspected of having ME are often hospitalized and started on empiric antimicrobial treatment, because of the potential adverse consequences of delaying the diagnosis or treatment. Multiplexed polymerase chain reaction panels are one of several rapid diagnostic technologies that have the potential to overcome some of the limitations of conventional diagnostic methods for ME. The BioFire FilmArray Meningitis/Encephalitis Panel was the first Food and Drug Administration–cleared multiplex polymerase chain reaction for the evaluation of cerebrospinal fluid samples, able to identify 14 organisms in a single test reaction. This newer rapid diagnostic tool has an overall high sensitivity and specificity for the diagnosis of ME with a fast turnaround time and has the potential to improve resource utilization for patients presenting with suspicion of ME. However, further research is needed to determine its optimal use in the evaluation of patients with suspected ME.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In this study, with a relatively small sample size, the positive and negative percent agreements of QIA/ME and FA/ME were slightly better than the specificity and sensitivity values seen in previous studies evaluating FA/ME.

    “In this study, with a relatively small sample size, the positive and negative percent agreements of QIA/ME and FA/ME (Tables 3 to 5) were slightly better than the specificity and sensitivity values seen in previous studies evaluating FA/ME (17–24).”
  • Herpesviruses included in the ME panel (HSV-1, HSV-2, CMV, VZV, and HHV-6) can enter a latent state; positive results may reflect latent viral genomes carried by CSF leukocytes or peripheral blood contamination from a traumatic lumbar puncture instead of genuine CNS involvement.

    “The interpretive challenge is heightened by the inherent capacity of the herpesviruses included in the ME panel (HSV‐1, HSV‐2, CMV, VZV, and HHV‐6) to enter a latent state. As a result, positive results may reflect latent viral genomes carried by CSF leukocytes or peripheral blood contamination from a traumatic lumbar puncture instead of genuine CNS involvement [20].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
