Zusammenfassung
Obwohl die anästhesieassoziierte Sterblichkeit mit 0,00068–0,00082 % seit Jahrzehnten auf niedrigem Niveau ist, zeigen aktuelle Studien eine weiterhin hohe durchschnittliche postoperative Letalität von 0,8–4 %. Neben chirurgisch bedingten schweren Komplikationen beeinflusst v. a. die patienteneigene Komorbidität das Behandlungsergebnis negativ. Risikofaktoren prädisponieren einerseits für akut auftretende Zwischenfälle (z. B. Myokardinfarkt), andererseits entsteht ein Großteil der letalen Komplikationen mit einer langsamen Progredienz, v. a. Infektionen oder Folgen der systemischen Inflammation. Deshalb besteht ein Zeitfenster zur Erkennung und zur Therapie zahlreicher perioperativer Komplikationen, das oft nicht zur Verbesserung des Behandlungsergebnisses genutzt wird.
In diesem Zusammenhang wurde der Begriff „failure to rescue“ (FTR) als Indikator der perioperativen Patientenversorgung eingeführt, gemeint ist derjenige Anteil von Patienten, die eine schwere postoperative Komplikation erleiden und letztendlich an dieser Komplikation versterben. Failure to rescue scheint in der perioperativen Medizin eine bislang unterschätzte Rolle zu spielen, aber einen signifikanten Anteil der postoperativen Letalität zu verursachen bzw. zumindest an deren Entstehung beteiligt zu sein. Während die Häufigkeit von postoperativen Komplikationen zwischen verschiedenen Krankenhäusern erstaunlich wenig variiert, unterscheidet sich die Letalität nach Komplikationen z. T. erheblich, was auf ein erhebliches Verbesserungspotenzial hinweist. Bei ca. 14 Mio. Operationen in Deutschland mit einer postoperativen Sterblichkeit von ca. 1 % und einem vermeidbaren FTR-Anteil von 40 % wären dies geschätzte 60.000 vermeidbare Todesfälle. Eine wesentliche Aufgabe der Zukunft wird es daher sein, FTR zu vermeiden. Hierfür müssen 1) die Risikopatienten identifiziert, 2) die Entstehung von postoperativen Komplikationen durch geeignete perioperative adjunktive Therapiestrategien möglichst vermieden, 3) ein Überwachungssystem zur Früherkennung von Komplikationen etabliert sowie 4) auftretende Komplikationen suffizient und frühzeitig behandelt werden.
Abstract
Although anesthesia-associated mortality has been significantly reduced down to 0.00068–0.00082 % over the last decades, recent studies have revealed a high perioperative mortality of 0.8− 4 %. Apart from anesthesia and surgery-induced major complications, perioperative mortality is primarily negatively influenced by individual patient comorbidities. These risk factors predispose for acute critical incidents (e.g. myocardial infarction); however, the majority of fatal complications are a result of slowly progressing conditions, particularly infections or the sequelae of systemic inflammation. This implicates a broad window of opportunity for the detection and treatment of slow-onset complications to improve the perioperative outcome. The term “failure to rescue” (FTR), i.e. the proportion of patients who die from major complications compared to the number of all patients with complications, has been introduced as a valid indicator for the quality of perioperative care. Growing evidence has already shown that FTR is an underestimated factor in perioperative medicine accounting for or at least being involved in the development of postoperative mortality. While the incidence of severe postoperative complications amazingly does not show much variation between hospitals, FTR shows significant differences implying a major potential for improvement. With 14 million surgical procedures per year in Germany, a postoperative mortality of approximately 1 % and an avoidable FTR rate of 40 % mean that there are an estimated 60,000 preventable deaths per year. Hence, in the future it will be imperative to (1) identify patients at risk, (2) to prevent the development of postoperative complications with the use of adequate adjunctive therapeutic strategies, (3) to establish surveillance and monitoring systems for the early detection of postoperative complications and (4) to treat postoperative complications efficiently and in time when they arise.
