목적: 국내에서 소아를 대상으로 시행하는 혈액배양의 적응증과 방법, 정도 관리 현황을 파악하고자 하였다. 방법: 종합병원에 근무하는 소아감염분과 전문의(소아감염)와 신생아집중치료센터를 운영하는 병원에근무하는 신생아분과 전문의(신생아)를 대상으로 온라인 설문조사를 하였다. 결과: 소아감염의 81.1% (30/37)와 신생아의 72.2% (52/72)가 설문에 응하였다. 적응증과 무관하게정규 검사로 혈액배양을 실시하는 경우는 소아감염의 33.3%, 신생아의 59.6%였다. 소아감염의 40% 와 신생아의 65.4%가 균혈증 의심 환자에서 혈액배양을 1회 시행한다고 했다. 가장 많이 사용되는 피부 소독제는 포비돈-아이오딘이었고, 여러 피부 소독제를 사용하는 경우 그 순서는 기관마다 다양하였다. 배양 양성률 및 오염률을 모니터링하는 기관은 전체의 2/3 정도였으나 결과를 채혈자에게 피드백하는 곳은 적었다. 채혈 담당자에게 정기적인 교육을 하는 곳은 전체의 1/2 이하였다. 결론: 기관별로 혈액배양의 적응증과 방법이 다양하였으며 정도 관리를 적극적으로 시행하는 병원은적었다. 소아에서 실시되는 혈액배양의 질 향상을 위해 표준 지침의 정립이 필요하며 정도 관리를 위한기관들의 노력이 요구된다.
Abstract
Purpose: Blood culture is an essential diagnostic tool and requires clear indications, proper techniques, and quality control. We aimed to investigate whether blood cultures in children are appropriate for indications, are performed correctly, and receive proper quality control. Methods: We conducted an online survey targeting pediatric infectious diseases (ID) specialists working in general hospitals and neonatologists (Neo) working at hospitals operating a neonatal intensive care unit in Korea. Results: Approximately 81.1% (30/37) of pediatric ID specialists and 72.2% (52/72) of Neo responded to the survey. Some of the respondents (33.3% of ID and 59.6% of Neo) performed blood culture as a regular test irrespective of the indication. Approximately 40% of ID and 65.4% of Neo ordered only one set of blood culture in patients suspected with bacteremia. The most commonly used disinfectant for skin preparation was povidone-iodine, while the skin preparation method varied by institution. Approximately two-thirds of the institutions were monitoring the blood culture contamination rate, whereas relatively few provided staff with feedback on that rate. In addition, less than half of the institutions were providing regular staff training on blood culture (40% of ID and 28.8% of Neo). Conclusions: The indication and methods of blood culture for children varied according to institution, and few hospitals exert effort in improving the quality of blood culture. Institutions have to strive constantly toward improvement of blood culture quality and evidence-based recommendations for pediatric blood cultures should be standardized.
