Sepsis und Multiorganversagen – Blutkulturdiagnostik: Herausforderung oder Routine?

Zusammenfassung

Die Untersuchung von Blutkulturen gehört zu den wichtigsten Elementen der Sepsisdiagnostik. Dennoch weisen Daten aus verschiedenen Studien darauf hin, dass im Vergleich zu anderen Ländern die Abnahmefrequenz von Blutkulturen in deutschen Krankenhäusern relativ gering ist. Mögliche Gründe hierfür könnten in der Wahrnehmung der Kliniker liegen, dass die Ergebnisse einer Blutkulturdiagnostik zu spät vorliegen oder, dass hohe Kontaminationsraten deren Aussagekraft einschränken. In diesem Artikel werden deshalb die wichtigsten Aspekte zur Qualitätssicherung der Blutkulturdiagnostik zusammengefasst, sowie innovative Ansätze vorgestellt.

Abstract

Blood cultures are an essential diagnostic tool to investigate suspected cases of sepsis. However, several studies indicate that (compared with other countries) blood culture diagnostics is only rarely performed in German healthcare facilities. Reasons for this are unknown, but could include clinicians' perception that the turn-around time of results is delayed or that contamination rates are high. Therefore, this article aims to summarize important aspects involved in assuring quality of blood culture diagnostics as well as innovative approaches.
