Quality indicators in intensive care medicine for Germany - fourth edition 2022.

The measurement of quality indicators supports quality improvement initiatives. The German Interdisciplinary Society of Intensive Care Medicine (DIVI) has published quality indicators for intensive care medicine for the fourth time now. After a scheduled evaluation after three years, changes in several indicators were made. Other indicators were not changed or only minimally. The focus remained strongly on relevant treatment processes like management of analgesia and sedation, mechanical ventilation and weaning, and infections in the ICU. Another focus was communication inside the ICU. The number of 10 indicators remained the same. The development method was more structured and transparency was increased by adding new features like evidence levels or author contribution and potential conflicts of interest. These quality indicators should be used in the peer review in intensive care, a method endorsed by the DIVI. Other forms of measurement and evaluation are also reasonable, for example in quality management. This fourth edition of the quality indicators will be updated in the future to reflect the recently published recommendations on the structure of intensive care units by the DIVI.

Quality indicators in intensive care medicine for Germany - third edition 2017.

Quality improvement in medicine is depending on measurement of relevant quality indicators. The quality indicators for intensive care medicine of the German Interdisciplinary Society of Intensive Care Medicine (DIVI) from the year 2013 underwent a scheduled evaluation after three years. There were major changes in several indicators but also some indicators were changed only minimally. The focus on treatment processes like ward rounds, management of analgesia and sedation, mechanical ventilation and weaning, as well as the number of 10 indicators were not changed. Most topics remained except for early mobilization which was introduced instead of hypothermia following resuscitation. Infection prevention was added as an outcome indicator. These quality indicators are used in the peer review in intensive care, a method endorsed by the DIVI. A validity period of three years is planned for the quality indicators.

End-of-life decisions in intensive care medicine-shared decision-making and intensive care unit length of stay.

BACKGROUND: Most deaths on the intensive care unit (ICU) occur after end-of-life decisions (EOLD) have been made. During the decision-making process, responsibility is often shared within the caregiver team and with the patients' surrogates. The intensive care unit length of stay (ICU-LOS) of surgical ICU-patients depends on the primary illness as well as on the past medical history. Whether an increasing ICU-LOS affects the process of EOLD making is unknown. METHODS: A retrospective analysis was conducted on all deceased patients (n = 303) in a 22-bed surgical ICU of a German university medical center. Patient characteristics were compared between surgical patients with an ICU-LOS up to 1 week and those with an ICU-LOS of more than 7 days. RESULTS: Deceased patients with a long ICU-LOS received more often an EOLD (83.2% vs. 63.6%, p = 0.001). Groups did not differ in urgency of admission. Attending intensivists participated in every EOLD. Participation of surgeons was significantly higher in patients with a short ICU-LOS (24.1%, p = 0.003), whereas nurses and the patients' surrogates were involved more frequently in patients with a long ICU-LOS (18.8%, p = 0.021 and 18.9%, p = 0.018, respectively). CONCLUSION: EOLDs of surgical ICU-patients are associated with the ICU-LOS. Reversal of the primary illness leads the early ICU course, while in prolonged ICU-LOS, the patients' predicted will and the expected post-ICU-quality of life gain interest. Nurses and the patients' surrogates participate more frequently in EOLDs with prolonged ICU-LOS. To improve EOLD making on surgical ICUs, the ICU-LOS associated participation of the different decision makers needs further prospective analysis.

Voluntary peer review as innovative tool for quality improvement in the intensive care unit--a retrospective descriptive cohort study in German intensive care units.

INTRODUCTION: Quality improvement and safety in intensive care are rapidly evolving topics. However, there is no gold standard for assessing quality improvement in intensive care medicine yet. In 2007 a pilot project in German intensive care units (ICUs) started using voluntary peer reviews as an innovative tool for quality assessment and improvement. We describe the method of voluntary peer review and assessed its feasibility by evaluating anonymized peer review reports and analysed the thematic clusters highlighted in these reports. METHODS: Retrospective data analysis from 22 anonymous reports of peer reviews. All ICUs - representing over 300 patient beds - had undergone voluntary peer review. Data were retrieved from reports of peers of the review teams and representatives of visited ICUs. Data were analysed with regard to number of topics addressed and results of assessment questionnaires. Reports of strengths, weaknesses, opportunities and threats (SWOT reports) of these ICUs are presented. RESULTS: External assessment of structure, process and outcome indicators revealed high percentages of adherence to predefined quality goals. In the SWOT reports 11 main thematic clusters were identified representative for common ICUs. 58.1% of mentioned topics covered personnel issues, team and communication issues as well as organisation and treatment standards. The most mentioned weaknesses were observed in the issues documentation/reporting, hygiene and ethics. We identified several unique patterns regarding quality in the ICU of which long-term personnel problems und lack of good reporting methods were most interesting Conclusion: Voluntary peer review could be established as a feasible and valuable tool for quality improvement. Peer reports addressed common areas of interest in intensive care medicine in more detail compared to other methods like measurement of quality indicators.

The German quality indicators in intensive care medicine 2013--second edition.

Quality indicators are key elements of quality management. The quality indicators for intensive care medicine of the German Interdisciplinary Society of Intensive Care Medicine (DIVI) from the year 2010 were recently evaluated when their validity time expired after two years. Overall one indicator was replaced and further three were in part changed. The former indicator I "elevation of head of bed" was replaced by the indicator "Daily multi-professional ward rounds with the documentation of daily therapy goals" and added to the indicator IV "Weaning and other measures to prevent ventilator associated pneumonias (short: Weaning/VAP Bundle)" (VAP = ventilator-associated pneumonia) which aims at the reduction of VAP incidence. The indicator VIII "Documentation of structured relative-/next-of-kin communication" was refined. The indicator X "Direction of the ICU by a specially trained certified intensivist with no other clinical duties in a department" was also updated according to recent study results. These updated quality indicators are part of the Peer Review in intensive care medicine. The next update of the quality indicators is due in 2016.

Managing end-of-life decision making in intensive care medicine--a perspective from Charité Hospital, Germany.

INTRODUCTION: End-of-life-decisions (EOLD) have become an important part of modern intensive care medicine. With increasing therapeutic possibilities on the one hand and many ICU-patients lacking decision making capacity or an advance directive on the other the decision making process is a major challenge on the intensive care unit (ICU). Currently, data are poor on factors associated with EOLD in Germany. In 2009, a new law on advance directives binding physicians and the patient's surrogate decision makers was enacted in Germany. So far it is unknown if this law influenced proceedings of EOLD making on the ICU. METHODS: A retrospective analysis was conducted on all deceased patients (n = 224) in a 22-bed surgical ICU of a German university medical center from 08/2008 to 09/2010. Patient characteristics were compared between patients with an EOLD and those without an EOLD. Patients with an EOLD admitted before and after change of legislation were compared with respect to frequencies of EOLD performance as well as advance directive rates. RESULTS: In total, 166 (74.1%) of deaths occurred after an EOLD. Compared to patients without an EOLD, comorbidities, ICU severity scores, and organ replacement technology did not differ significantly. EOLDs were shared within the caregiverteam and with the patient's surrogate decision makers. After law enacting, no differences in EOLD performance or frequency of advance directives (8.9% vs. 9.9%; p = 0.807) were observed except an increase of documentation efforts associated with EOLDs (18.7% vs. 43.6%; p<0.001). CONCLUSIONS: In our ICU EOLD proceedings were performed patient-individually. But EOLDs follow a standard of shared decision making within the caregiverteam and the patient's surrogate decision makers. Enacting a law on advance directives has not affected the decision making-process in EOLDs nor has it affected population's advance care planning habits. However, it has led to increased EOLD-associated documentation on the ICU. TRIAL REGISTRATION: [corrected] ClinicalTrials.gov NCT01294189.

[Peer review in ICU]. / Peer Reviews in der Intensivmedizin.

Peer reviewing in intensive care medicine is an evaluation process that promotes a professional understanding of quality and the exchange of experience in intensive care. It will help integrate evidence-based knowledge into the treatment process at an earlier stage and thus improve the quality of intensive care and intensive nursing care. The process is a learning experience for all involved and is highly satisfying to the participants. The exchange of experience is an essential part of quality control.

Gastrointestinal function in intensive care patients: terminology, definitions and management. Recommendations of the ESICM Working Group on Abdominal Problems.

PURPOSE: Acute gastrointestinal (GI) dysfunction and failure have been increasingly recognized in critically ill patients. The variety of definitions proposed in the past has led to confusion and difficulty in comparing one study to another. An international working group convened to standardize the definitions for acute GI failure and GI symptoms and to review the therapeutic options. METHODS: The Working Group on Abdominal Problems (WGAP) of the European Society of Intensive Care Medicine (ESICM) developed the definitions for GI dysfunction in intensive care patients on the basis of the available evidence and current understanding of the pathophysiology. RESULTS: Definitions for acute gastrointestinal injury (AGI) with its four grades of severity, as well as for feeding intolerance syndrome and GI symptoms (e.g. vomiting, diarrhoea, paralysis, high gastric residual volumes) are proposed. AGI is a malfunctioning of the GI tract in intensive care patients due to their acute illness. AGI grade I = increased risk of developing GI dysfunction or failure (a self-limiting condition); AGI grade II = GI dysfunction (a condition that requires interventions); AGI grade III = GI failure (GI function cannot be restored with interventions); AGI grade IV = dramatically manifesting GI failure (a condition that is immediately life-threatening). Current evidence and expert opinions regarding treatment of acute GI dysfunction are provided. CONCLUSIONS: State-of-the-art definitions for GI dysfunction with gradation as well as management recommendations are proposed on the basis of current medical evidence and expert opinion. The WGAP recommends using these definitions for clinical and research purposes.

Quality indicators in intensive care medicine: why? Use or burden for the intensivist.

In order to improve quality (of therapy), one has to know, evaluate and make transparent, one's own daily processes. This process of reflection can be supported by the presentation of key data or indicators, in which the real as-is state can be represented. Quality indicators are required in order to depict the as-is state.Quality indicators reflect adherence to specific quality measures. Continuing registration of an indicator is useless once it becomes irrelevant or adherence is 100%. In the field of intensive care medicine, studies of quality indicators have been performed in some countries. Quality indicators relevant for medical quality and outcome in critically ill patients have been identified by following standardized approaches.Different German societies of intensive care medicine have finally agreed on 10 core quality indicators that will be valid for two years and are currently recommended in German intensive care units (ICUs).

Peer reviewing critical care: a pragmatic approach to quality management.

Critical care medicine frequently involves decisions and measures that may result in significant consequences for patients. In particular, mistakes may directly or indirectly derive from daily routine processes. In addition, consequences may result from the broader pharmaceutical and technological treatment options, which frequently involve multidimensional aspects. The increasing complexity of pharmaceutical and technological properties must be monitored and taken into account. Besides the presence of various disciplines involved, the provision of 24-hour care requires multiple handovers of significant information each day. Immediate expert action that is well coordinated is just as important as a professional handling of medicine's limitations.Intensivists are increasingly facing professional quality management within the ICU (Intensive Care Unit). This article depicts a practical and effective approach to this complex topic and describes external evaluation of critical care according to peer reviewing processes, which have been successfully implemented in Germany and are likely to gain in significance.

Levosimendan may improve survival in patients requiring mechanical assist devices for post-cardiotomy heart failure.

INTRODUCTION: Most case series suggest that less than half of the patients receiving a mechanical cardiac assist device as a bridge to recovery due to severe post-cardiotomy heart failure survive to hospital discharge. Levosimendan is the only inotropic substance known to improve medium term survival in patients suffering from severe heart failure. METHODS: This retrospective analysis covers our single centre experience. Between July 2000 and December 2004, 41 consecutive patients were treated for this complication. Of these, 38 patients are included in this retrospective analysis as 3 patients died in the operating room. Levosimendan was added to the treatment protocol for the last nine patients. RESULTS: Of 29 patients treated without levosimendan, 20 could be weaned off the device, 9 survived to intensive care unit discharge, 7 left hospital alive and 3 survived 180 days. All 9 patients treated with levosimendan could be weaned, 8 were discharged alive from ICU and hospital, and 7 lived 180 days after surgery (p < 0.002 for 180 day survival). Plasma lactate after explantation of the device was significantly lower (p = 0.002), as were epinephrine doses. Time spent on renal replacement therapy was significantly shorter (p = 0.023). CONCLUSION: Levosimendan seems to improve medium term survival in patients failing to wean off cardiopulmonary bypass and requiring cardiac assist devices as a bridge to recovery. This retrospective analysis justifies prospective randomised investigations of levosimendan in this group of patients.

Small-dose epoprostenol decreases systemic oxygen consumption and splanchnic oxygen extraction during normothermic cardiopulmonary bypass.

Normothermic, nonpulsatile cardiopulmonary bypass (CPB) impairs systemic and splanchnic oxygen transport and increases gastrointestinal permeability. It is an important therapeutic goal to avoid splanchnic dysoxia during CPB. Small-dose prostacyclin therapy improves splanchnic oxygen transport and microcirculation in septic patients. In this study, we sought to determine if during cardiac surgery, the prostacyclin analog epoprostenol improves the balance of systemic and splanchnic oxygen transport. Eighteen patients undergoing cardiac valve replacement were randomized to receive either epoprostenol (3 ng x kg(-1) x min(-1)) or placebo during, and for 1 hour after, surgery. Systemic and splanchnic oxygen delivery, consumption, and extraction and arterial, mixed venous, and hepato-venous lactate concentrations were measured before, during, and after CPB. Gastrointestinal permeability was measured 1 day before and 1 day after surgery using the triple sugar permeability test. During CPB, the epoprostenol group had decreased systemic oxygen consumption and splanchnic oxygen extraction (P = 0.024). These effects were not present 1 hour after the end of epoprostenol infusion. The study was not adequately powered to determine whether epoprostenol altered the trend towards increased lactate metabolism and increased postoperative gastrointestinal permeability, nor could we demonstrate any differences between groups in clinically relevant end-points. In conclusion, these findings suggest that during normothermic CPB, small-dose epoprostenol therapy may reduce systemic oxygen consumption and splanchnic oxygen extraction.

Arterio-venous gradients of free energy change for assessment of systemic and splanchnic perfusion in cardiac surgery patients.

OBJECTIVE: Adequacy of organ perfusion depends on sufficient oxygen supply in relation to the metabolic needs. The aim of this study was to evaluate the relationship between gradients of free energy change, and the more commonly used parameter for the evaluation of the adequacy of organ perfusion, such as oxygen-extraction in patients undergoing valve replacement surgery using normothermic cardiopulmonary bypass (CPB). METHODS: In 43 cardiac patients, arterial, mixed venous, and hepato-venous blood samples were taken synchronously after induction of anaesthesia (preCPB), during CPB, and 2 and 7 h after admission to the intensive care unit (ICU+2, ICU+7). Blood gas analysis, cardiac output, and hepato-splanchnic blood flow were measured. Free energy change gradients between mixed venous and arterial (-deltadeltaG(v - a)) and hepato-venous and arterial (-deltadeltaG(hv - a)) compartments were calculated. MEASUREMENTS AND RESULTS: Cardiac index (CI) increased from 1.9 (0.7) to 2.8 (1.3) L/min/m (median, inter-quartile range) (p = 0.001), and hepato-splanchnic blood flow index (HBFI) from 0.6 (0.22) to 0.8 (0.53) L/min/m (p = 0.001). Despite increasing flow, systemic oxygen extraction increased after CPB from 24 (10)% to 35 (10)% at ICU+2 (p = 0.002), and splanchnic oxygen extraction increased during CPB from 37 (19)% to 52 (14)% (p = 0.001), and remained high thereafter. After CPB, high splanchnic and systemic gradients of free energy change gradients were associated with high splanchnic and systemic oxygen extraction, respectively (p = 0.001, 0.033, respectively). CONCLUSION: Gradients of free energy change may be helpful in characterising adequacy of perfusion in cardiac surgery patients independently from measurements or calculations of data from oxygen transport.

Treatment of severe pulmonary hemorrhage after cardiopulmonary bypass by selective, temporary balloon occlusion.

Severe pulmonary bleeding causes frequent mortality, particularly if this event occurs during separation from extracorporeal circulation during cardiac surgery. We present a new approach to treat this life-threatening complication: temporary balloon occlusion of the pulmonary artery feeding the involved lobe. On attempting to wean a 71-yr-old female patient from cardiopulmonary bypass after aortic valve replacement, she lost more than 2 L of blood through her trachea over approximately 15 min and severe gas embolism into the left atrium was visualized on transesophageal echocardiography. As the bleeding was too vigorous to be localized by fiberoptic bronchoscopy, an interventional cardiologist was consulted. After localizing the affected lobe using fluoroscopy, he inflated a balloon dilating catheter in the lower lobe artery. This effectively stopped the bleeding. Separation from extracorporeal circulation was uneventful using one-lung ventilation to prevent further gas embolism. Sixteen hours after the end of surgery the catheter could be deflated and removed without any further intervention. The patient made an excellent recovery.

Treatment of acute heart failure in an infant after cardiac surgery using levosimendan.

An infant, 2 months old, underwent cardiac surgery because of congenital heart defects and pulmonary hypertension. Surgery was performed in hypothermia and cardiac standstill. On the second day after surgery the infant had to be resuscitated due to a combination of acute left-ventricular failure, pulmonary vascular hypertension and a slight right-to-left-shunt. A breakthrough in the treatment was achieved by using levosimendan to improve left-ventricular function and to decrease vascular resistance.
