[Sepsis incidence in Germany and worldwide : Current knowledge and limitations of research using health claims data]
Abstract
Sepsis is the life-threatening organ dysfunction caused by a dysregulated host response to infection. With an estimated 48.9 million patients being affected by sepsis every year, sepsis is one of the most common diseases worldwide. Approximately 20% of global deaths are considered as sepsis-related. In Germany, a study based on nationwide hospital discharge data of almost all German hospitals found a sepsis incidence of 158 per 100,000 inhabitants. Estimates based on clinical patient data from other industrialized countries were 780/100,000 (Sweden) and 517/100,000 (USA). However, the comparability of incidence rates is limited due to the different data sources and sepsis case identification strategies used. In all, 41.7% of sepsis patients died in hospital, and 17.9% of intensive care unit patients are affected by sepsis. Case identification of sepsis in health claims data has a low sensitivity; therefore, it is likely that sepsis incidence is underestimated using these data, as many sepsis cases are not coded as such. For the purpose of epidemiological surveillance, health claims data should be complemented by other data sources such as registries or electronic health records.
Sepsis ist die lebensbedrohliche Organdysfunktion aufgrund einer inadäquaten Wirtsantwort auf Infektionen. Jährlich erkranken geschätzte 48,9 Mio. Patienten an einer Sepsis, sie ist damit eine der häufigsten Erkrankungen weltweit. Etwa 20 % aller Todesfälle gelten als mit Sepsis assoziiert. In Deutschland wurde eine Inzidenz der Sepsis basierend auf einer Auswertung der Abrechnungsdaten nahezu aller deutschen Krankenzhäuser von 158/100.000 Einwohner ermittelt. Schätzungen auf Basis klinischer Patientenakten aus anderen Industrienationen liegen bei 780/100.000 (Schweden) und 517/100.000 Einwohner (USA), allerdings sind die Inzidenzraten aufgrund der unterschiedlichen Datenquellen und Art der Sepsisfallidentifikation nur eingeschränkt vergleichbar. Von den mit Sepsis behandelten Patienten verstarben 41,7 % im Krankenhaus. Auf der Intensivstation sind 17,9 % der Patienten von einer Sepsis betroffen. Die Identifikation von Sepsisfällen in Routinedaten weist eine geringe Sensitivität auf, es ist daher von einer deutlichen Unterschätzung der Sepsisfälle in Routinedaten auszugehen, da viele Sepsisfälle nicht als solche kodiert werden. Zur epidemiologischen Überwachung der Sepsisfallzahlen sollten daher neben Routinedaten auch weitere Datenquellen, wie Register oder elektronische Krankenakten, genutzt werden.
