Interventions/Control_1

We recommend not to use antibiotics when all the followings are satisfied: 1) viral pathogen is proved by multiplex PCR, 2) patient is respiratory and circulatory stable, and 3) white blood cell count <13.0x103/mm3 and CRP <5.0mg/dL. However, initiation or selection of antibiotics are decided according to physicians' judgement.

Results

There were no differences in antibiotic use (84% vs 75%; p = 0.14), broad-spectrum antibiotic use (33% vs 34%; p = 0.91), or the duration of antibiotic use within 14 days of admission (6.0 vs 7.0 d; p = 0.45) between the pre- and postmultiplex polymerase chain reaction periods.

Baseline Characteristics

Ninety-six and 85 children were enrolled during the pre- and postmultiplex polymerase chain reaction periods, respectively. Rapid antigen tests identified pathogens in 22% of the children (n = 21) during the premultiplex polymerase chain reaction period, whereas rapid antigen tests and/or multiplex polymerase chain reaction testing identified pathogens in 67% of the children (n = 57) during the postmultiplex polymerase chain reaction period (p < 0.001).

Participant flow

Consecutive children with respiratory infections who were admitted to the PICU between December 2017 and November 2018 (premultiplex polymerase chain reaction period) and between March 2019 and February 2020 (postmultiplex polymerase chain reaction period).

Adverse events

Nothing

Outcome measures

The primary outcome was the pathogen identification rate during the pre- (RATs only) and post-mPCR (RATs and mPCR testing) periods. Conventional RATs were available for six pathogens. mPCR testing was performed using the FilmArray respiratory panel (BioFire Diagnostics, Salt Lake City, UT) (3), which included 17 viruses and three bacterial pathogens (Supplemental Digital Content 1, https://links.lww.com/PCC/B831).

The secondary outcome was the use and duration of antibiotics used within 14 days of admission to the PICU, before and after the implementation of mPCR testing. During the post-mPCR period, reduced antibiotic use was recommended for a stable patient depending on the virus species and laboratory test results (Supplemental Digital Content 1, https://links.lww.com/PCC/B831).
