Patient Monitoring Alarms in an Intensive Care Unit: Observational Study With Do-It-Yourself Instructions.

BACKGROUND: As one of the most essential technical components of the intensive care unit (ICU), continuous monitoring of patients' vital parameters has significantly improved patient safety by alerting staff through an alarm when a parameter deviates from the normal range. However, the vast number of alarms regularly overwhelms staff and may induce alarm fatigue, a condition recently exacerbated by COVID-19 and potentially endangering patients. OBJECTIVE: This study focused on providing a complete and repeatable analysis of the alarm data of an ICU's patient monitoring system. We aimed to develop do-it-yourself (DIY) instructions for technically versed ICU staff to analyze their monitoring data themselves, which is an essential element for developing efficient and effective alarm optimization strategies. METHODS: This observational study was conducted using alarm log data extracted from the patient monitoring system of a 21-bed surgical ICU in 2019. DIY instructions were iteratively developed in informal interdisciplinary team meetings. The data analysis was grounded in a framework consisting of 5 dimensions, each with specific metrics: alarm load (eg, alarms per bed per day, alarm flood conditions, alarm per device and per criticality), avoidable alarms, (eg, the number of technical alarms), responsiveness and alarm handling (eg alarm duration), sensing (eg, usage of the alarm pause function), and exposure (eg, alarms per room type). Results were visualized using the R package ggplot2 to provide detailed insights into the ICU's alarm situation. RESULTS: We developed 6 DIY instructions that should be followed iteratively step by step. Alarm load metrics should be (re)defined before alarm log data are collected and analyzed. Intuitive visualizations of the alarm metrics should be created next and presented to staff in order to help identify patterns in the alarm data for designing and implementing effective alarm management interventions. We provide the script we used for the data preparation and an R-Markdown file to create comprehensive alarm reports. The alarm load in the respective ICU was quantified by 152.5 (SD 42.2) alarms per bed per day on average and alarm flood conditions with, on average, 69.55 (SD 31.12) per day that both occurred mostly in the morning shifts. Most alarms were issued by the ventilator, invasive blood pressure device, and electrocardiogram (ie, high and low blood pressure, high respiratory rate, low heart rate). The exposure to alarms per bed per day was higher in single rooms (26%, mean 172.9/137.2 alarms per day per bed). CONCLUSIONS: Analyzing ICU alarm log data provides valuable insights into the current alarm situation. Our results call for alarm management interventions that effectively reduce the number of alarms in order to ensure patient safety and ICU staff's work satisfaction. We hope our DIY instructions encourage others to follow suit in analyzing and publishing their ICU alarm data.

Transition from in-hospital ventilation to home ventilation: process description and quality indicators.

The current demographic development of our society results in an increasing number of elderly patients with chronic diseases being treated in the intensive care unit. A possible long-term consequence of such a treatment is that patients remain dependent on certain invasive organ support systems, such as long-term ventilator dependency. The main goal of this project is to define the transition process between in-hospital and out of hospital (ambulatory) ventilator support. A further goal is to identify evidence-based quality indicators to help define and describe this process. This project describes an ideal sequence of processes (process chain), based on the current evidence from the literature. Besides the process chain, key data and quality indicators were described in detail. Due to the limited project timeline, these indicators were not extensively tested in the clinical environment. The results of this project may serve as a solid basis for proof of feasibility and proof of concept investigations, optimize the transition process of ventilator-dependent patients from a clinical to an ambulatory setting, as well as reduce the rate of emergency re-admissions.

A Perceval Valve in Active Infective Bioprosthetic Valve Endocarditis: Case Report.

The case is presented of a 72-year-old male patient suffering from active infective aortic prosthetic endocarditis two months after emergency surgery with aortic valve implantation, and who underwent aortic arch reconstruction using a Dacron patch, due to the spontaneous post-procedural migration of a transcatheter-implanted aortic valve. The heart team considered transcatheter valve implantation (TAVI) due to the increased operative risk demonstrated by a EuroSCORE II of 10.9%, including chronic obstructive pulmonary disease (GOLD 3), cirrhosis (Child-B), esophageal varicose stage 2, chronic renal failure stage 3, and reduced left ventricular ejection fraction. Subsequently, the EuroSCORE II was extremely high (76%) due to active infective prosthetic endocarditis and the aortic arch reoperation. A sutureless aortic valve was implanted and a pericardial patch repair of the aortic ascending and arch completed. Sternal re-stabilization was required postoperatively. The patient was discharged home after 42 days, and no recurrent endocarditis was diagnosed during follow up.

Surgery for prosthetic valve endocarditis: associations between morbidity, mortality and costs.

OBJECTIVES: Surgery for prosthetic valve endocarditis (PVE) is associated with significant morbidity and mortality as well as with increased resource utilization and costs. For risk and cost reduction, an understanding of contributing factors and interrelations is essential. METHODS: Out of 1080 heart valve procedures performed between January 2010 and December 2012, 41 patients underwent surgery for PVE. Complete economic data were available for 30 of them (study cohort). The patients' mean age was 64 ± 12 years (range 37-79 years), and 73% were men. The clinical course was reviewed and morbidity, mortality and costs as well as associations between them were analysed. The cost matrix for each individual patient was obtained from the Institute for the Hospital Remuneration System (InEK GmbH, Germany). The median follow-up was 2.6 years [interquartile range (IQR) 3.7 years; 100% complete]. RESULTS: Preoperative status was critical (EuroSCORE II >20%) in 43% of patients. Staphylococci were the most common infecting micro-organisms (27%). The operative mortality rate (≤30 days) was 17%. At 1 year, the overall survival rate was 71 ± 9%. At least one disease- or surgery-related complication affected 21 patients (early morbidity 70%), >1 complication affected 12 patients (40%). There was neither a recurrence of endocarditis, nor was a reoperation required. The mean total hospital costs were 42.6 ± 37.4 Thousand Euro (T€), median 25.7 T€, IQR 28.4 T€ and >100 T€ in 10% of cases. Intensive care unit/intermediate care (ICU/IMC) and operation accounted for 40.4 ± 18.6 and 25.7 ± 12.1% of costs, respectively. There was a significant correlation (Pearson's sample correlation coefficient) between total costs and duration of hospital stay (r = 0.83, P < 0.001) and between ICU/IMC costs and duration of ICU/IMC stay (r = 0.97, P < 0.001). The median daily hospital costs were 1.8 T€/day, but >2.4 T€/day in 25% of patients (upper quartile). The following pattern of associations was identified (P < 0.05). Early mortality was related to preoperative morbidity and postoperative renal failure. Early morbidity was associated with preoperative morbidity and urgency. Total costs were mainly explained by preoperative morbidity, postoperative morbidity and urgency. High EuroSCORE II, complex surgery, need for mechanical circulatory support as well as postoperative mortality and morbidity increased daily costs. CONCLUSIONS: The timely diagnosis and treatment of these patients must be a priority, as preoperative morbidity is the major contributor towards mortality, morbidity and costs after surgery for PVE.

Early deep sedation is associated with decreased in-hospital and two-year follow-up survival.

INTRODUCTION: There is increasing evidence that deep sedation is detrimental to critically ill patients. The aim of this study was to examine effects of deep sedation during the early period after ICU admission on short- and long-term survival. METHODS: In this observational, matched-pair analysis, patients receiving mechanical ventilation that were admitted to ICUs of a tertiary university hospital in six consecutive years were grouped as either lightly or deeply sedated within the first 48 hours after ICU admission. The Richmond Agitation-Sedation Score (RASS) was used to assess sedation depth (light sedation: -2 to 0; deep: -3 or below). Multivariate Cox regression was conducted to investigate the impact of early deep sedation within the first 48 hours of admission on in-hospital and two-year follow-up survival. RESULTS: In total, 1,884 patients met inclusion criteria out of which 27.2% (n = 513) were deeply sedated. Deeply sedated patients had longer ventilation times, increased length of stay and higher rates of mortality. Early deep sedation was associated with a hazard ratio of 1.661 (95% CI: 1.074 to 2.567; P = 0.022) for in-hospital survival and 1.866 (95% CI: 1.351 to 2.576; P < 0.001) for two-year follow-up survival. CONCLUSIONS: Early deep sedation during the first 48 hours of intensive care treatment was associated with decreased in-hospital and two-year follow-up survival. Since early deep sedation is a modifiable risk factor, this data shows an urgent need for prospective clinical trials focusing on light sedation in the early phase of ICU treatment.

Early levosimendan administration is associated with decreased mortality after cardiac surgery.

PURPOSE: The aim of this study was to assess the effects on postoperative outcome of levosimendan with respect to timing of its administration in cardiac surgery patients. MATERIALS AND METHODS: Levosimendan administration was triggered by a severely reduced left ventricular systolic function (left ventricular ejection fraction, <35%) and/or signs of a low cardiac output syndrome. A total of 159 patients were retrospectively assigned depending on an early (perioperatively up to the first hour after intensive care unit [ICU] admission) vs late (later than the first hour after ICU admission) start of treatment. RESULTS: Patients receiving levosimendan after the first hour of ICU admission (n = 89) had a significantly increased inhospital (P = .004) and 1-year (P = .027) mortality. Duration of mechanical ventilation (P = .002), incidence of renal dysfunction (P = .002), and need of renal replacement therapy (P = .032) were significantly increased in the late start group. A late start of levosimendan treatment was associated with an odds ratio of 2.258 (95% confidence interval, 1.139-4.550; P = .021) for inhospital mortality and an adjusted hazard ratio of 1.827 (95% confidence interval, 1.155-2.890; P = .010) for 1-year survival. CONCLUSIONS: Findings of this retrospective analysis favor an "early," that is, intraoperatively up to the first hour after ICU admission, start of perioperative levosimendan treatment to maximize its ability to reduce mortality and morbidity.

Prone position during ECMO is safe and improves oxygenation.

PURPOSE: Combination of prone positioning (PrP) and extracorporeal membrane oxygenation (ECMO) might be beneficial in severe acute respiratory distress syndrome (ARDS), because both approaches are recommended. However, PrP during ECMO might be associated with complications such as dislocation of ECMO cannulae. We investigated complications and change of oxygenation effects of PrP during ECMO to identify "responders" and discuss our results considering different definitions of response in the literature.
 METHODS: Retrospective analysis of complications, gas exchange, and invasiveness of mechanical ventilation during first and second PrP on ECMO at specified time points (before, during, and after PrP). We used multivariate nonparametric analysis of longitudinal data (MANOVA) to compare changes of mechanical ventilation and hemodynamics associated with the first and second procedures.
 RESULTS: In 12 ECMO patients, 74 PrPs were performed (median ECMO duration: 10 days (IQR: 6.3-15.5 days)). No dislocations of intravascular catheters/cannulae, endotracheal tubes or chest tubes were observed. Two PrPs had to be interrupted (endotracheal tube obstruction, acute pulmonary embolism). PaO2/FiO2-ratio increased associated with the first and second PrP (p = 0.002) and lasted after PrP in 58% of these turning procedures ("responders") without changes in ECMO blood flow, respiratory pressures, minute ventilation, portion of spontaneously triggered breathing, and compliance. Hemodynamics did not change with exception of increased mean pulmonary arterial pressure during PrP and decrease after PrP (p<0.001), while norepinephrine dosage decreased (p = 0.03) (MANOVA).
 CONCLUSIONS: Prone position during ECMO is safe and improves oxygenation even after repositioning. This might ameliorate hypoxemia and reduce the harm from mechanical ventilation.

Computed tomography findings in septic patients with acute respiratory distress syndrome: correlation with survival and pulmonary versus extrapulmonary septic focus.

OBJECTIVE: The objective of this study was to evaluate computed tomography (CT) findings in patients with sepsis with unknown inflammatory focus and acute respiratory distress syndrome. METHODS: Acute respiratory distress syndrome findings on CT of 36 patients with sepsis were graded on a 6-point scale, and the percentage of affected lung was estimated. Resulting CT scores were correlated to intensive care scores and survival. RESULTS: Forty-four percent of the patients died, revealing a significantly higher CT score than survivors (P = 0.01). Survivors showed larger areas of unaffected lung (P < 0.001), whereas patients with fatal outcome had more ground-glass opacities (P = 0.002; sensitivity, 73%; specificity, 57%) and traction bronchiectasis (P = 0.009; sensitivity, 54%; specificity, 68%). Pulmonary findings on CT did not allow discriminating between a pulmonary and extrapulmonary focus. No significant coherence between CT score and intensive care scores could be revealed. CONCLUSIONS: A CT scoring system based on pulmonary findings in patients with sepsis with acute respiratory distress syndrome comprises prognostic implications in terms of the patients' survival.

Predictive ability of the stability and workload index for transfer score to predict unplanned readmissions after ICU discharge.

OBJECTIVE: Unplanned readmission of hospitalized patients to an ICU is associated with an increased mortality and hospital length of stay. The ability to identify patients at risk, who would benefit from prolonged ICU treatment, is limited. The aim of this study is to validate a previously published numerical index named the Stability and Workload Index for Transfer in a heterogeneous group of ICU patients. DESIGN: In this retrospective data analysis, the Stability and Workload Index for Transfer score was calculated for all patients, and the ability of the score to predict readmission was compared with the original publication. SETTING: Four ICUs, one intermediate care unit, and one postanesthesia care unit of the department of anesthesia and intensive care of a university hospital. PATIENTS: All consecutive patients treated in one of the units. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Unplanned ICU readmissions or unexpected death within 7 days of ICU discharge. The data of 7,175 patients were included in the analysis. Five hundred ninety-six patients were readmitted or died within 7 days of discharge. The patients who are readmitted to the ICU are significantly older and have significantly higher scores that define the severity of disease at the time of admission and discharge of their first ICU stay. The source of admission for the initial ICU stay did not differ (p = 0.055), and the last Glasgow Coma Scale and the last PaO2/FIO2 ratio before discharge from the ICU were higher in patients who did not need a readmission to the ICU. The performance of the Stability and Workload Index for Transfer score is poor with an area under the receiver operator curve of 0.581 (95% CI, 0.556-0.605; p < 0.001). CONCLUSIONS: Based on the data from our patients, the proposed Stability and Workload Index for Transfer score by Gajic et al is not ideal in aiding the clinician in the decision, if a patient can be discharged safely from the ICU and further research is necessary to define the patients at risk for readmission.

Catecholamine dosing and survival in adult intensive care unit patients.

BACKGROUND: Volume management and vasopressor support remain the gold standard of critical care for patients with shock. However, prolonged therapy with catecholamines in high doses is associated with a negative patient outcome. The aim of the present study was to analyze the administered levels of catecholamines over time with respect to survival, and to identify a cut-off to allow a prediction of survival. METHODS: Consecutively, 9,108 adult patients during 22 months were evaluated. This group included 1,543 patients treated with epinephrine and/or norepinephrine with any dose at any time. Time and dosages of the applied drugs, the sequential organ failure assessment and acute and chronic health evaluation II scores on admission and daily, the length of intensive care unit stay, and the outcomes were recorded. RESULTS: The non-survivors received higher doses of norepinephrine and epinephrine than the survivors (p < 0.001). The receiver operator characteristic curve for the area under the curve with non-survival as the classifier revealed a cut-off level of 294.33 µg/kg for norepinephrine with a sensitivity of 74.73 % and a specificity of 70.48 % and a cut-off for epinephrine of 70.36 µg/kg with a sensitivity of 83.87 % and a specificity of 72.79 %. Dose-dependent time curves using these cut-off values were calculated. CONCLUSIONS: Survival of patients with prolonged therapy with norepinephrine and epinephrine above the evaluated thresholds is poor, whereas short-term application of high-dose catecholamines is not associated with poor outcome. Therefore, it remains for the individual clinician, patients, and their surrogates to decide whether the use of high doses of vasopressors is appropriate in view of the low probability of survival.

A survey of standardised drug syringe label use in European anaesthesiology departments.

CONTEXT: Standardised drug syringe labelling may reduce drug errors, but data on drug syringe labelling use in European anaesthesiology departments are lacking. OBJECTIVES: Survey investigating if standardised drug syringe labelling is used, and if there are geographical, demographic and professional differences in hospitals with and without use of drug syringe labelling. DESIGN: Structured, web-based anonymised questionnaire. SETTING: European anaesthesia departments. PARTICIPANTS: Members of the European Society of Anaesthesiology. INTERVENTION: Online survey from 2 February to 12 April 2011. MAIN OUTCOME MEASURE: Standardised drug syringe labelling use and, if yes, drug syringe labelling for insulin and norepinephrine. METHODS: Descriptive and comparative analyses of users and nonusers of standardised drug syringe labelling. RESULTS: One thousand and sixty-four of 4163 members (25.6%) from 72 countries participated, among whom 660 (62.0%) used standardised drug syringe labelling; in Northern and Western Europe, there were 428 users of drug syringe labelling and 112 nonusers, and in Southern and Eastern Europe, there were 184 users and 255 nonusers (P < 0.001). Three hundred and ninety-four (37%) respondents used standardised drug syringe labelling hospital-wide; 202 (30.1%) used International Organisation of Standardisation-based standardised drug syringe labelling, 101 (15.1%) used similar systems, 278 (41.5%) used other systems and 89 (13.3%) used labels supplied by drug manufacturers. The label colour for insulin was reported as white or 'none' in 519 (76.7%) answers and another colour in 158 (23.3%). The label colour for norepinephrine was reported as violet in 206 (30.4%) answers, white or 'none' in 226 (33.3%), red in 114 (16.8%) and another colour in 132 (19.5%). A standardised drug syringe labelling system supplied by the pharmaceutical industry was supported by 819 (76.9%) respondents, and not supported by 227 (21.3%). CONCLUSION: A majority of European anaesthesiology departments used standardised drug syringe labelling, with regional differences and mostly without following an international standard. Thus, there are options for quality improvement in drug syringe labelling.

Effects of intensivist coverage in a post-anaesthesia care unit on surgical patients' case mix and characteristics of the intensive care unit.

INTRODUCTION: There is an increasing demand for intensive care in hospitals, which can lead to capacity limitations in the intensive care unit (ICU). Due to postponement of elective surgery or delayed admission of emergency patients, outcome may be negatively influenced. To optimize the admission process to intensive care, the post-anaesthesia care unit (PACU) was staffed with intensivist coverage around the clock. The aim of this study is to demonstrate the impact of the PACU on the structure of ICU-patients and the contribution to overall hospital profit in terms of changes in the case mix index for all surgical patients. METHODS: The administrative data of all surgical patients (n = 51,040) 20 months prior and 20 months after the introduction of a round-the-clock intensivist staffing of the PACU were evaluated and compared. RESULTS: The relative number of patients with longer length of stay (LOS) (more than seven days) in the ICU increased after the introduction of the PACU. The average monthly number of treatment days of patients staying less than 24 hours in the ICU decreased by about 50% (138.95 vs. 68.19 treatment days, P <0.005). The mean LOS in the PACU was 0.45 (± 0.41) days, compared to 0.27 (± 0.2) days prior to the implementation. The preoperative times in the hospital decreased significantly for all patients. The case mix index (CMI) per hospital day for all surgical patients was significantly higher after the introduction of a PACU: 0.286 (± 0.234) vs. 0.309 (± 0.272) P <0.001 CMI/hospital day. CONCLUSIONS: The introduction of a PACU and the staffing with intensive care staff might shorten the hospital LOS for surgical patients. The revenues for the hospital, as determined by the case mix index of the patients per hospital day, increased after the implementation of a PACU and more patients can be treated in the same time, due to a better use of resources.

Analysis of event logs from syringe pumps: a retrospective pilot study to assess possible effects of syringe pumps on safety in a university hospital critical care unit in Germany.

BACKGROUND: Medication errors occur in approximately one out of five doses in a typical hospital setting. Patients in the intensive care unit (ICU) are particularly susceptible to errors during the application of intravenous drugs as they receive numerous potent drugs applied by syringe pumps. OBJECTIVE: The aim of this study was to analyse the effects on potential harmful medication errors and to address factors that have potential for improving medication safety after the introduction of a standardized drug library into syringe pumps with integrated decision support systems. METHODS: A team of physicians and nurses developed a dataset that defined standardized drug concentrations, application rates and alert limits to prevent accidental overdosing of intravenous medications. This dataset was implemented in 100 syringe pumps with the ability to log programming errors, alerts, reprogramming events and overrides ('smart pumps'). In this retrospective pilot study, all pump-related transaction data were obtained from the pump logs, by downloading the data from the pumps, covering 20 months of use between 1 April 2008 and 30 November 2009. Patient data were gathered from the electronic patient charts. The study was performed in a cardiothoracic ICU of the Charité University Hospital, Berlin, Germany. RESULTS: A total of 7884 patient treatment days and 133,601 infusion starts were evaluated. The drug library with the features of the dose rate was used in 92.8% of the syringe pump starts, in 1.5% of the starts a manual dosing mode without the use of the drug library was used and in 5.7% of the starts the mode 'mL/h', without any calculation features, was used. The most frequently used drugs were vasoactive drugs, followed by sedation medication. The user was alerted for a potentially harmful overdosing in 717 cases and in 66 cases the pumps were reprogrammed after the alert. During the early morning hours a higher rate of alarms was generated by the pumps, compared with the rest of the day. CONCLUSIONS: Syringe pumps with integrated safety features have the capacity to intercept medication errors. The structured evaluation of the bedside programming history in log recordings is an important benefit of smart pumps, as this enables the users to obtain an objective measurement of infusion practice, which can be used to provide team feedback and to optimize the programming of the pumps. Further research will show if the combination of these data with physiological data from ICU patients can improve the safety of pump-driven intravenous medication.

Standardised drug labelling in intensive care: results of an international survey among ESICM members.

PURPOSE: Standardised coloured drug labels may increase patient safety in the intensive care unit (ICU). The rates of adherence to standardised drug syringe labelling (DSL) in European and non-European ICUs, and the standards applied are not known. The aim of this survey among ESICM members was to assess if and what standardised drug syringe labelling is used, if the standards for drug syringe labelling are similar internationally and if intensivists expect that standardised DSL should be delivered by the pharmaceutical industry. METHODS: A structured, web-based, anonymised survey on standardised DSL, performed among ESICM members (March-May 2011; Clinicaltrials.gov NCT01232088). Descriptive data analysis was performed and Fisher's exact test was applied where applicable. RESULTS: Four hundred eighty-two submissions were analysed (20 % non-European). Thirty-five percent of the respondents reported that standardised drug labelling was used hospital-wide, and 39 % reported that standardised DSL was used in their ICU (Europe: Northern 53 %, Western 52 %, Eastern 17 %, Southern 22 %). The International Organization of Standardization (ISO) 26825 norm in its original form was used by 30 %, an adapted version by 19 % and local versions by 45 %; 6 % used labels that were included in the drug's packaging. Eighty percent wished that the pharmaceutical industry supplied ISO 26825 norm labelling together with the drugs. CONCLUSIONS: Standardised DSL is not widely applied in European and non-European ICUs and mostly does not adhere strictly to the ISO norm. The frequency and quality of DSL differs to a great extent among European regions. This leaves much room for improvement.

Computed tomography findings from patients with ARDS due to Influenza A (H1N1) virus-associated pneumonia.

PURPOSE: The purpose of this study was to retrospectively evaluate whether computed tomography (CT) findings have prognostic value for the prediction of mortality and severity of the clinical course in patients presenting with early stage of acute respiratory distress syndrome (ARDS) due to swine-origin influenza A (S-OIV). MATERIALS AND METHODS: Chest CT (16-/64-row multidetector CT) of 23 patients (of whom 9 patients died) were retrospectively reviewed by three independent blinded observers. The CT findings were graded on a 3-point scale (1: normal attenuation, 2: ground-glass attenuation, 3: consolidation). The extent of each abnormality was determined by visually estimating the percentage (to the nearest 10%) of the affected lung parenchyma in each zone and multiplied by the CT-score described above. RESULTS: All patients presented with a mixture of bilateral patchy consolidations and ground glass opacities. Spearman rank correlation in evaluation of the presence and extent of lung abnormalities by the three different observers was good (correlation coefficient, 0.876-0.922; p < 0.001). The overall CT-score in survivors (mean, 96.0 (± 26.2); range, 53-158) was significantly lower than that in non-survivors (mean, 116.2 (± 14.0); range, 101-139). ROC analysis revealed an area under curve of 0.79 (p = 0.021) for the CT score with an optimal cutoff value of a CT-score of 100 for prediction of survival, with a sensitivity of 100% and a specificity of 64% (accuracy, 78%). For this optimal cutoff, Kaplan-Meier estimator showed a significant difference for the survival ratio (p = 0.011). CONCLUSION: In patients with severe ARDS due to S-OIV-infection, the CT-score has a prognostic value in the prediction of mortality.

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.

Impact of adherence to standard operating procedures for pneumonia on outcome of intensive care unit patients.

BACKGROUND: Pneumonia accounts for almost half of intensive care unit (ICU) infections and nearly 60% of deaths from nosocomial infections. It increases hospital stay by 7-9 days, crude mortality by 70% and attributable mortality by 30%. OBJECTIVE: Our purpose was to assess the impact of standard operating procedures adapted to the local resistance rates in the initial empirical treatment for pneumonia on duration of first pneumonia episode, duration of mechanical ventilation, and length of ICU stay. DESIGN: Prospective observational cohort study with retrospective expert audit. SETTING: Five anesthesiologically managed ICUs at University hospital (one cardio-surgical, one neurosurgical, two interdisciplinary, and one intermediate care). PATIENTS: Of 524 consecutive patients with > or = 36 hr ICU treatment 131 patients with pneumonia on ICU were identified. Their first pneumonia episode was evaluated daily for adherence to standard operating procedures. Pneumonia was diagnosed according to the American Thoracic Society guidelines. Patients with > 70% compliance were assigned to high adherence group (HAG), patients with < or = 70% to low adherence group (LAG). MEASUREMENTS AND RESULTS: HAG consisted of 45 (49 first episode) patients, LAG of 86 (82 first episode) patients, respectively. Mean duration of treatment of the first pneumonia episode was 10.11 +/- 7.95 days in the LAG and 6.22 +/- 3.27 days in the HAG (p = 0.001). Duration of mechanical ventilation was 317.59 +/- 336.18 hrs in the LAG and 178.07 +/- 191.33 hrs in the HAG (p = 0.017). Length of ICU stay was 20.24 +/- 16.59 days in the LAG and 12.04 +/- 10.42 days in the HAG (p = 0.001). LIMITATIONS: Barriers in compliance need further evaluation. CONCLUSION: Adherence to standard operating procedure is associated with a shorter duration of treatment of first pneumonia episode, a shorter duration of mechanical ventilation, and a shorter ICU stay.
