Abstract

Inappropriate antibiotic usage can contribute to the promotion of resistant bacteria. In an effort to reduce antibiotic length of therapy (LOT), we initiated a performance improvement project utilizing pneumonia polymerase chain reaction (PCR) testing in ventilated pediatric intensive care unit (PICU) patients suspected of tracheitis or pneumonia. This was a single-center cohort intervention study that compared pre- and postimplementation patients. The intervention was the use of a pneumonia PCR panel on all PICU patients undergoing an evaluation for acute tracheitis or pneumonia during the postimplementation period. The inclusion criteria were either acute or acute on chronic respiratory failure. After an 8-month period, the charts were reviewed from both cohorts and baseline data, and outcome data were compared by statistical analysis. A total of 41 preimplementation and 30 postimplementation patients were compared, and no baseline differences were found except postimplementation patients being slightly older (133 vs. 56 months, p-value = 0.040). Analysis of the primary outcome measures found that the time to identification of organism (5 vs. 67 hours) and LOT (5 vs. 9 days, p < 0.001) were shorter in postimplementation patients compared with preimplementation patients. Antibiotics were changed based on the results of the pneumonia PCR on 18 of 30 patients (60%). There was no difference in ventilator-free days, PICU length of stay, or mortality. In conclusion, pneumonia PCR panel testing leads to more rapid results and was associated with reduced antibiotic LOT.
