Addition of point-of-care test reduces antibiotic prescription in hospitalised children with suspected respiratory tract infection: A pre-test-post-test study

Aim: Prompt and accurate aetiological diagnostics are needed if physicians are to improve and target antibiotic treatment. We aimed to investigate whether antibiotic-prescribing decisions are improved with availability of point-of-care polymerase chain reaction (POC-PCR) diagnostic testing of children with suspected respiratory tract infection, and if it had an impact on referral for additional medical procedures.

Methods: This was a single-centre one-group pre-test-post-test study. Children visiting our paediatric department with respiratory tract infection symptoms were included if the treating paediatrician was considering an antibiotic prescription. Throat swabs were analysed for pathogens using POC-PCR. The paediatrician registered treatment decisions, referrals for additional procedures and decisions about hospitalisation into a questionnaire before and after receiving the POC-PCR results.

Results: We included 95 children. The availability of results from POC-PCR analysis significantly changed the prescribed antibiotic treatment to non-antibiotic treatment in 46% (36%-56%) of the children and the reverse in 2% (1%-8%). Paediatricians referred significantly fewer patients to additional medical procedures with availability of POC-PCR.

Conclusion: POC-PCR significantly reduced the odds of antibiotic prescription and referral for additional medical procedures. Thus, POC-PCR presents an opportunity to improve antibiotic-prescribing practices if it is combined with standard clinical evaluation.
