Evidence-based medicine is often inadequately implemented in intensive care units (ICU); the aim of this study was to improve its implementation via a technical feedback system, using key performance indicators (KPI). The study evaluated 205 patients treated in a cardiac surgical ICU over a 6-month period (3 months before and 3 months after implementation of the feedback system). KPI adherence rates for sedation, delirium and pain monitoring, and completion of a weaning protocol before and after the implementation of the feedback system, were compared. Adherence rates for pain and delirium monitoring, and implementation of the weaning protocol, were significantly increased by the intervention. Adherence to KPIs for sedation, which were high at baseline, could not be further improved. Daily display of KPI implementation had a positive effect on adherence to standard operating procedures. Adherence to guidelines may be improved by using this feedback system as part of the clinical routine.

72We studied the influence of sequential involvement of the gastrointestinal (GI) tract on the development of multiple organ dysfunction (MOD) after cardiopulmonary bypass (CPB). One hundred and forty-six patients undergoing elective cardiac surgery were included in this prospective observational study. Standardized oral inert-sugar tests (sucrose, lactulose, mannitol, sucralose) were performed before and after CPB in different patients. Enzyme-linked immunosorbent assay of plasma levels of endotoxin core antibodies (EndoCAb) were performed peri-operatively. The functional mucosal surface was calculated from the amount of mannitol absorbed from the GI tract. Lower urine concentrations of absorbed mannitol were observed preoperatively in patients developing MOD. In binary logistic regression this was an independent parameter. Decreased plasma concentrations of EndoCAb after surgery were seen in every patient, but were more significant in patients developing MOD. A reduced pre-operative functional mucosal surface may predict the early occurrence of MOD after surgery.

In areas requiring maximum safety like intensive care units or operating room departments, modern quality management and risk management are essential. Treatment of critically ill patients is associated with high risk and, therefore, demands risk management and quality management. External quality assessment in intensive care medicine has been developed based on a core data set and quality indicators. A peer review procedure has been established. In addition, regional networks of intensive care physicians result in improved local networking. In intensive care medicine, this innovative modular system of quality management and risk management is pursued more consequently than in any other specialty.

Levosimendan is a recently developed drug which is not yet approved for clinical routine use in Germany. The clinical use is limited to a few selected cases and it has been used as a salvage therapy in patients with severe heart insufficiency. As a potent inodilator it has been given to patients with severe heart failure, when all other therapeutic options have failed. However, in some European countries levosimendan is used in clinical routine situations and the European Society of Cardiologists has included the drug in their guidelines for treatment of acute heart failure. The following article describes the main pharmacological characteristics of levosimendan and summarises the indications for this new drug for physicians working in the field of anaesthesia or intensive care.
