ObjectiveTo establish the efficacy of an algorithm based on the biomarker procalcitonin (PCT) to reduce antibiotic exposure in pediatric patients with lower respiratory tract infection (LRTI).Materials And MethodsThe clinical data of 357 patients (<14 years of age) who were discharged home with LRTI from January 1, 2010 to July 31, 2016 were analyzed. Antibiotic exposure, antibiotic prescription rate, length of hospital stay, and antibiotic-associated adverse effects were compared between the PCT group (n = 183) and the standard group (n = 174) using SAS 9.1.3 software.ResultsThe overall adverse effect rates were similar in both the PCT and standard groups: 42 (22.95%) and 51 (29.31%), respectively. The length of hospital stay was not significantly different between the PCT (9.96 ± 5.81 days) and standard groups (10.58 ± 4.24 days) (difference: -0.62%; 95% CI: -1.68 to 0.43). Antibiotic prescribing rates were significantly different in the PCT group compared to the standard group: 54.64% versus 83.91% (difference: -29.26%; 95% CI: -38.31, -20.22; p = 0.23). Mean duration of antibiotic exposure in the PCT group (3.98 ± 2.17 days) was lower than the standard groups (6.66 ± 5.59 days) (difference: -2.68%; 95% CI: -3.21 to -2.16).ConclusionThis study showed that PCT guidance of antibiotic treatment in children and adolescents with LRTI reduced the duration of antibiotic exposure and antibiotic prescribing rates, but did not affect the adverse effect rate and length of hospital stay.© 2017 S.
