초록
목적: 본 연구는 30일 이상 90일 미만의 발열이 있는 영아에서 경험적 항생제 사용에 미치는 요소를 조사하였다. 방법: 2010년 1월부터 2016년 12월까지 부산대학교 어린이병원에 발열이 있는 이전에 건강했던 영아를 대상으로 임상양상, 검사소견, 항생제 사용에 대해 의무기록을 후향적으로 분석하였다. 호흡기 바이러스는 다중 역전사 중합 연쇄반응검사로 검출하여 1–3일 후 보고되었고, enterovirus는 중합 연쇄반응검사로 검출하여 수시간 만에 보고되었다. 결과: 366명의 대상자 중 129명은 경험적 항생제를 사용하였고 237명은 경험적 항생제를 사용하지 않았다. 입원 전 발열기간이 긴 경우와 호흡기 증상이 있을 때, 아파보일 때, CRP 상승 시 경험적 항생제 사용이 많았다. 경험적 항생제를 사용하지 않은 환자의 재입원율이 낮았다. Enterovirus polymerase chain reaction (PCR)이 검출된 대부분의 환자는 경험적 항생제를 사용하지 않았다. Respiratory virus multiplex reverse transcriptase (RT)-PCR 결과는 경험적 항생제 사용에 차이를 보이지 않았다. 결론: 본 연구에서 respiratory virus multiplex RT-PCR은 항생제 처방에 영향을 주지 않았고 enterovirus PCR은 항생제 처방에 영향을 주었다. Respiratory virus multiplex RT-PCR 결과가 신속하게 보고된다면 항생제 사용에 영향을 줄 것이다.
Abstract
Purpose: This study investigated the factors affecting the use of empirical antibiotics in febrile infants from 1 month to less than 3 months. Methods: We retrospectively reviewed the medical records of hospitalized previously healthy infants with fever in Pusan National University Children's Hospital from January 2010 to December 2016. Clinical features, laboratory findings and antibiotic therapy were analyzed. Respiratory viruses were identified by multiplex reverse transcriptase polymerase chain reaction (RT-PCR) and were reported after 1–3 days. Enterovirus were identified by real time polymerase chain reaction (PCR) and were reported in several hours. Results: The 129 of 366 subjects used empirical antibiotics and 237 patients didn't used empirical antibiotics. Empirical antibiotics were used more frequently when the fever was longer before admission, respiratory symptoms and ill being appearances were present and C-reactive protein was elevated. The rate of readmission was low in the group not used empirical antibiotics. Most of the patients detected by enterovirus PCR in cerebrospinal fluid didn't used empirical antibiotics. The results of respiratory virus multiplex RT-PCR showed no difference in the use of empirical antibiotics. Conclusions: In our study, empirical antibiotic prescriptions were affected not respiratory virus multiplex RT-PCR but enterovirus PCR. If multiplex RT-PCR were reported more rapid turn around time, it will affect antibiotic use.
