Turnaround time for the BioFire FilmArray Pneumonia panel plus versus standard microbiological methods.
| Diagnostic method | Patients (n) | Turnaround time | Time differencea | p-valuea |
|---|---|---|---|---|
| FAP plus | 96 | 2.6 (2.2–3.4) | N.A | N.A |
| In-house PCR | 87 | 24.1 (19.6–27.8) | 21.0 (16.3–24.7) | < 0.001 |
| Sputum culture | 96 | 57.5 (26.9–94.4) | 48.6 (24.0–91.5) | < 0.001 |
| Pneumococcal antigen | 62 | 1.3 (0.9–1.8) | − 1.2 (− 2.0 to (− 0.5)) | < 0.001 |

Comparison of the turnaround time for different microbiological diagnostic methods used in this study. Numbers presented are median hours with IQR if not otherwise specified. P-values are calculated with Student’s paired t-test on logarithm-transformed times.
FAP plus, Biomérieux BioFire FilmArray Pneumonia panel plus; PCR, polymerase chain reaction; POC, point of care; N.A., not applicable; IQR, inter-quartile range.
aCompared to the FAP plus.
bTurnaround time was not recorded for the POC Influenza test (ID NOW). It was directly available in the ED, with an analysis time of approximately 15 min.
