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

Nutritional Management in Children and Adolescents with Severe Neurological Impairment-Who Cares? A Web-Based Survey Among Pediatric Specialists in Germany

BACKGROUND

Nutritional management of children and adolescents with severe neurological impairment (SNI) is challenging. A web-based survey was distributed to identify the present situation and the knowledge of the involved medical professionals in Germany.

METHODS

The survey was created with LimeSurvey, and access data were distributed by several medical societies. Eighty-three questions covered four topics: "general information," "gastro- and jejunostomy procedure," "handling of gastrostomies and feeding tubes," and "nutritional management and follow-up of children and adolescents with SNI." A descriptive analysis was performed with Microsoft Excel.

RESULTS

A total of 156 participated (65 completed and 91 partially), 27% being pediatric gastroenterologists, 23% pediatric neurologists, and 10% pediatric surgeons. The most common indications for gastrostomy and tube feeding were oropharyngeal dysfunction and failure to thrive. Many patients were still underweight after some months of enteral feeding. The procedure of gastrostomy and handling recommendations varied broadly. Frequently, standard operating procedures (SOPs) and written local guidelines did not exist, and there was a considerable request for training. Only 53% of participants were aware of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition position paper published in 2017, even fewer (38%) followed the guidelines. The recommended measures to assess a nutritional status were often not respected.

CONCLUSION

Nutritional management of children and adolescents with SNI in Germany is still strongly deficient. Despite the international guideline of 2017, few colleagues are aware of and adhere to the recommendations. This could be improved by interdisciplinary teaching and evaluation of the reasons for noncompliance. The procedure of gastrostomy and the patients' follow-up vary widely. Therefore, modified SOPs should be developed.

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.

Effectiveness of an intensive care telehealth programme to improve process quality (ERIC): a multicentre stepped wedge cluster randomised controlled trial

PURPOSE

Supporting the provision of intensive care medicine through telehealth potentially improves process quality. This may improve patient recovery and long-term outcomes. We investigated the effectiveness of a multifaceted telemedical programme on the adherence to German quality indicators (QIs) in a regional network of intensive care units (ICUs) in Germany.

METHODS

We conducted an investigator-initiated, large-scale, open-label, stepped-wedge cluster randomised controlled trial enrolling adult ICU patients with an expected ICU stay of ≥ 24 h. Twelve ICU clusters in Berlin and Brandenburg were randomly assigned to three sequence groups to transition from control (standard care) to the intervention condition (telemedicine). The quality improvement intervention consisted of daily telemedical rounds guided by eight German acute ICU care QIs and expert consultations. Co-primary effectiveness outcomes were patient-specific daily adherence (fulfilled yes/no) to QIs, assessed by a central end point adjudication committee. Analyses used mixed-effects logistic modelling adjusted for time. This study is completed and registered with ClinicalTrials.gov (NCT03671447).

RESULTS

Between September 4, 2018, and March 31, 2020, 1463 patients (414 treated on control, 1049 on intervention condition) were enrolled at ten clusters, resulting in 14,783 evaluated days. Two randomised clusters recruited no patients (one withdrew informed consent; one dropped out). The intervention, as implemented, significantly increased QI performance for "sedation, analgesia and delirium" (adjusted odds ratio (99.375% confidence interval [CI]) 5.328, 3.395-8.358), "ventilation" (OR 2.248, 1.198-4.217), "weaning from ventilation" (OR 9.049, 2.707-30.247), "infection management" (OR 4.397, 1.482-13.037), "enteral nutrition" (OR 1.579, 1.032-2.416), "patient and family communication" (OR 6.787, 3.976-11.589), and "early mobilisation" (OR 3.161, 2.160-4.624). No evidence for a difference in adherence to "daily multi-professional and interdisciplinary clinical visits" between both conditions was found (OR 1.606, 0.780-3.309). Temporal trends related and unrelated to the intervention were detected. 149 patients died during their index ICU stay (45 treated on control, 104 on intervention condition).

CONCLUSION

A telemedical quality improvement program increased adherence to seven evidence-based German performance indicators in acute ICU care. These results need further confirmation in a broader setting of regional, non-academic community hospitals and other healthcare systems.

Does adherence to a quality indicator regarding early weaning from invasive ventilation improve economic outcome? A single-centre retrospective study

OBJECTIVES

To measure and assess the economic impact of adherence to a single quality indicator (QI) regarding weaning from invasive ventilation.

DESIGN

Retrospective observational single-centre study, based on electronic medical and administrative records.

SETTING

Intensive care unit (ICU) of a German university hospital, reference centre for acute respiratory distress syndrome.

PARTICIPANTS

Records of 3063 consecutive mechanically ventilated patients admitted to the ICU between 2012 and 2017 were extracted, of whom 583 were eligible adults for further analysis. Patients' weaning protocols were evaluated for daily adherence to quality standards until ICU discharge. Patients with <65% compliance were assigned to the low adherence group (LAG), patients with ≥65% to the high adherence group (HAG).

PRIMARY AND SECONDARY OUTCOME MEASURES

Economic healthcare costs, clinical outcomes and patients' characteristics.

RESULTS

The LAG consisted of 378 patients with a median negative economic results of -€3969, HAG of 205 (-€1030), respectively (p<0.001). Median duration of ventilation was 476 (248; 769) hours in the LAG and 389 (247; 608) hours in the HAG (p<0.001). Length of stay (LOS) in the LAG on ICU was 21 (12; 35) days and 16 (11; 25) days in the HAG (p<0.001). LOS in the hospital was 36 (22; 61) days in the LAG, and within the HAG, respectively, 26 (18; 48) days (p=0.001).

CONCLUSIONS

High adherence to this single QI is associated with better clinical outcome and improved economic returns. Therefore, the results support the adherence to QI. However, the examined QI does not influence economic outcome as the decisive factor.

Impact on antimicrobial consumption of procalcitonin-guided antibiotic therapy for pneumonia/pneumonitis associated with aspiration in comatose mechanically ventilated patients: a multicenter, randomized controlled study

Background

In comatose patients receiving oro-tracheal intubation for mechanical ventilation (MV), the risk of aspiration is increased. Aspiration can lead to chemical pneumonitis (inflammatory reaction to the gastric contents), or aspiration pneumonia (infection caused by inhalation of microorganisms). Distinguishing between the two types is challenging. We tested the interest of using a decisional algorithm based on procalcitonin (PCT) values to guide initiation and discontinuation of antibiotic therapies in intubated patients.

Methods

The PROPASPI (PROcalcitonin Pneumonia/pneumonitis Associated with ASPIration) trial is a multicenter, prospective, randomized, controlled, single-blind, superiority study comparing two strategies: (1) an intervention group where threshold PCT values were used to guide initiation and discontinuation of antibiotics (PCT group); and (2) a control group, where antibiotic therapy was managed at the physician’s discretion. Patients aged 18 years or over, intubated for coma (Glasgow score ≤ 8), with MV initiated within 48 h after admission, were eligible. The primary endpoint was the duration of antibiotic treatment during the first 15 days after admission to the ICU.

Results

From 24/2/2015 to 28/8/2019, 1712 patients were intubated for coma in the 5 participating centers, of whom 166 were included in the study. Data from 159 were available for intention-to-treat analysis: 81 in the PCT group, and 78 in the control group. Overall, 67 patients (43%) received antibiotics in the intensive care unit (ICU); there was no significant difference between groups (37 (46%) vs 30 (40%) for PCT vs control, p = 0.432). The mean duration of antibiotic treatment during the first 15 days in the ICU was 2.7 ± 3.8 days; there was no significant difference between groups (3.0 ± 4.1 days vs 2.3 ± 3.4 days for PCT vs control, p = 0.311). The mean number of days under MV was significantly higher in the PCT group (3.7 ± 3.6 days) than in controls (2.7 ± 2.5 days, p = 0.033). The duration of ICU stay was also significantly longer in the PCT group: 6.4 ± 6.5 days vs 4.6 ± 3.5 days in the control group (p = 0.043). After adjustment for SAPS II score, the difference in length of stay and duration of mechanical ventilation between groups was no longer significant.

Conclusion

The use of PCT values to guide therapy, in comparison to the use of clinical, biological (apart from PCT) and radiological criteria, does not modify exposure to antibiotics in patients intubated for coma.

The future development of intensive care quality indicators - a methods paper

Introduction: Medical quality indicators (QI) are important tools in the evaluation of medical quality. Their development is subject to specific methodological requirements, which include practical applicability. This is especially true for intensive care medicine with its complex processes and their interactions. This methods paper presents the status quo and shows necessary methodological developments for intensive care QI. For this purpose, a cooperation with the Association of the Scientific Medical Societies' Institute for Medical Knowledge Management (AWMF-IMWi) was established. Methodology: Review of published German manuals for QI development from guidelines and narrative review of quality indicators with a focus on evidence and consensus-based guideline recommendations. Future methodological adaptations of indicator development for improved operationalization, measurability and pilot testing are presented, and a development process is proposed. Results: The development of intensive care quality indicators in Germany is based on an established process. In the future, additional evaluation criteria (QUALIFY criteria) will be applied to assess the evidence base. In addition, a continuous exchange between the national steering committee of the DIVI responsible for QI development and guideline development groups involved in intensive care medicine is planned. Conclusion: Intensive care quality indicators will have to meet improved methodological requirements in the future by means of an improved development process. Future QI development is intended to improve the structure of the development process, with a focus on scientific evidence and a link to guideline projects. This is intended to achieve the goal of a broad application of QI and to further evaluate its relevance for patient outcome and performance of institutions.

Enhanced Recovery after Intensive Care (ERIC): study protocol for a German stepped wedge cluster randomised controlled trial to evaluate the effectiveness of a critical care telehealth program on process quality and functional outcomes

INTRODUCTION

Survival after critical illness has noticeably improved over the last decades due to advances in critical care medicine. Besides, there is an increasing number of elderly patients with chronic diseases being treated in the intensive care unit (ICU). More than half of the survivors of critical illness suffer from medium-term or long-term cognitive, psychological and/or physical impairments after ICU discharge, which is recognised as post-intensive care syndrome (PICS). There are evidence-based and consensus-based quality indicators (QIs) in intensive care medicine, which have a positive influence on patients' long-term outcomes if adhered to.

METHODS AND ANALYSIS

The protocol of a multicentre, pragmatic, stepped wedge cluster randomised controlled, quality improvement trial is presented. During 3 predefined steps, 12 academic hospitals in Berlin and Brandenburg, Germany, are randomly selected to move in a one-way crossover from the control to the intervention condition. After a multifactorial training programme on QIs and clinical outcomes for site personnel, ICUs will receive an adapted, interprofessional protocol for a complex telehealth intervention comprising of daily telemedical rounds at ICU. The targeted sample size is 1431 patients. The primary objective of this trial is to evaluate the effectiveness of the intervention on the adherence to eight QIs daily measured during the patient's ICU stay, compared with standard of care. Furthermore, the impact on long-term recovery such as PICS-related, patient-centred outcomes including health-related quality of life, mental health, clinical assessments of cognition and physical function, all-cause mortality and cost-effectiveness 3 and 6 months after ICU discharge will be evaluated.

ETHICS AND DISSEMINATION

This protocol was approved by the ethics committee of the Charité-Universitätsmedizin, Berlin, Germany (EA1/006/18). The results will be published in a peer-reviewed scientific journal and presented at international conferences. Study findings will also be disseminated via the website (www.eric-projekt.net).

Effects of pain, sedation and delirium monitoring on clinical and economic outcome: A retrospective study

BACKGROUND

Significant improvements in clinical outcome can be achieved by implementing effective strategies to optimise pain management, reduce sedative exposure, and prevent and treat delirium in ICU patients. One important strategy is the monitoring of pain, agitation and delirium (PAD bundle). We hypothesised that there is no sufficient financial benefit to implement a monitoring strategy in a Diagnosis Related Group (DRG)-based reimbursement system, therefore we expected better clinical and decreased economic outcome for monitored patients.

METHODS

This is a retrospective observational study using routinely collected data. We used univariate and multiple linear analysis, machine-learning analysis and a novel correlation statistic (maximal information coefficient) to explore the association between monitoring adherence and resulting clinical and economic outcome. For univariate analysis we split patients in an adherence achieved and an adherence non-achieved group.

RESULTS

In total 1,323 adult patients from two campuses of a German tertiary medical centre, who spent at least one day in the ICU between admission and discharge between 1. January 2016 and 31. December 2016. Adherence to PAD monitoring was associated with shorter hospital LoS (e.g. pain monitoring 13 vs. 10 days; p<0.001), ICU LoS, duration of mechanical ventilation shown by univariate analysis. Despite the improved clinical outcome, adherence to PAD elements was associated with a decreased case mix per day and profit per day shown by univariate analysis. Multiple linear analysis did not confirm these results. PAD monitoring is important for clinical as well as economic outcome and predicted case mix better than severity of illness shown by machine learning analysis.

CONCLUSION

Adherence to PAD bundles is also important for clinical as well as economic outcome. It is associated with improved clinical and worse economic outcome in comparison to non-adherence in univariate analysis but not confirmed by multiple linear analysis.

Clinical decision-making on spinal cord injury-associated pneumonia: a nationwide survey in Germany

STUDY DESIGN

Survey study.

OBJECTIVES

Spinal cord injury (SCI)-associated pneumonia (SCI-AP) is associated with poor functional recovery and a major cause of death after SCI. Better tackling SCI-AP requires a common understanding on how SCI-AP is defined. This survey examines clinical algorithms relevant for diagnosis and treatment of SCI-AP.

SETTING

All departments for SCI-care in Germany.

METHODS

The clinical decision-making on SCI-AP and the utility of the Centers for Disease Control and Prevention (CDC) criteria for diagnosis of 'clinically defined pneumonia' were assessed by means of a standardized questionnaire including eight case vignettes of suspected SCI-AP. The diagnostic decisions based on the case information were analysed using classification and regression trees (CART).

RESULTS

The majority of responding departments were aware of the CDC-criteria (88%). In the clinical vignettes, 38-81% of the departments diagnosed SCI-AP in accordance with the CDC-criteria and 7-41% diagnosed SCI-AP in deviation from the CDC-criteria. The diagnostic agreement was not associated with the availability of standard operating procedures for SCI-AP management in the departments. CART analysis identified radiological findings, fever, and worsened gas exchange as most important for the decision on SCI-AP. Frequently requested supplementary diagnostics were microbiological analyses, C-reactive protein, and procalcitonin. For empirical antibiotic therapy, the departments used (acyl-)aminopenicillins/β-lactamase inhibitors, cephalosporins, or combinations of (acyl-)aminopenicillins/β-lactamase inhibitors with fluoroquinolones or carbapenems.

CONCLUSIONS

This survey reveals a diagnostic ambiguity regarding SCI-AP despite the awareness of CDC-criteria and established SOPs. Heterogeneous clinical practice is encouraging the development of disease-specific guidelines for diagnosis and management of SCI-AP.

Combination of National Quality Assurance Data Collection With a Standard Operating Procedure in Community-Acquired Pneumonia: A Win-Win Strategy?

PURPOSE

The primary contact for German physicians with national quality assurance in community-acquired pneumonia (CAP) is frequently experienced as time-consuming obligatory documentation. Since the regular feedback loop stretches up to 18 months, the immediate impact on quality is perceived as rather low. Ultimately, a method leading to increase in the quality of data collection, clarification on expected clinical treatment standards, and improvement in the acceptance and feedback mechanism is needed.

METHODS

We developed a form merging data collection for quality indicators with a standard operating procedure (SOP) in CAP and implemented it in the daily routine of a university's department for internal medicine. Fulfillment of quality indicators before and after the implementation of the new form was measured.

RESULTS

Critical parameters such as the documentation of breathing rate and clinical parameters at discharge strongly improved after implementation of the intervention. Uncritical parameters showed slight improvement or stable results at a high level.

CONCLUSION

The combination of collection of quality data with a clinical SOP and context information may improve the impact of quality measures by increasing acceptance, quality of data capture, short-loop feedback, and possibly quality of care.

Existence and role of standard operating procedures in the emergency department : A national online survey

BACKGROUND

In recent years, increases in the number of patients in emergency departments (ED) have led to continuous work intensification. To handle this problem, the treatment effectiveness has to be maximized. One strategy that may help to optimize workflow is the use of standard operating procedures (SOPs). We investigated the existence of SOPs and subjective effects on treatment in German EDs.

METHODS

We performed an online survey from February 2015 until June 2016. We collected data regarding the existence of SOPs, health care level, medical field, work experience, and education. All professional groups participating in the treatment of patients were requested to take part in the survey.

RESULTS

Seventy-five percent of the 589 participants in the survey confirmed the existence of SOPs in their EDs. SOPs were more frequently available in hospitals with higher health care levels. Participants working in EDs without SOPs felt less confident regarding treatment of patients. More than 85% of these participants were in favor of having SOPs. The absence of SOPs was associated with a subjective delay in patient treatment.

CONCLUSION

Most of the EDs had available SOPs. In departments without SOPs, most physicians wanted them to be implemented. SOPs seemed adequate in terms of supporting workflow and satisfaction with patients' treatment.

Implementation and Evaluation of a Web-Based Distribution System For Anesthesia Department Guidelines and Standard Operating Procedures: Qualitative Study and Content Analysis

BACKGROUND

Digitization is spreading exponentially in medical care, with improved availability of electronic devices. Guidelines and standard operating procedures (SOPs) form an important part of daily clinical routine, and adherence is associated with improved outcomes.

OBJECTIVE

This study aimed to evaluate a digital solution for the maintenance and distribution of SOPs and guidelines in 2 different anesthesiology departments in Switzerland.

METHODS

A content management system (CMS), WordPress, was set up in 2 tertiary-level hospitals within 1 year: the Department of Anesthesiology and Pain Medicine at the Kantonsspital Lucerne in Lucerne, Switzerland, as an open-access system, followed by a similar system for internal usage in the Department of Anaesthesiology and Pain Medicine of the Inselspital, Bern University Hospital, in Bern, Switzerland. We analyzed the requirements and implementation processes needed to successfully set up these systems, and we evaluated the systems' impact by analyzing content and usage.

RESULTS

The systems' generated exportable metadata, such as traffic and content. Analysis of the exported metadata showed that the Lucerne website had 269 pages managed by 44 users, with 88,124 visits per month (worldwide access possible), and the Bern website had 341 pages managed by 35 users, with 1765 visits per month (access only possible from within the institution). Creation of an open-access system resulted in third-party interest in the published guidelines and SOPs. The implementation process can be performed over the course of 1 year and setup and maintenance costs are low.

CONCLUSIONS

A CMS, such as WordPress, is a suitable solution for distributing and managing guidelines and SOPs. Content is easily accessible and is accessed frequently. Metadata from the system allow live monitoring of usage and suggest that the system be accepted and appreciated by the users. In the future, Web-based solutions could be an important tool to handle guidelines and SOPs, but further studies are needed to assess the effect of these systems.

Mortality attributable to hospital acquired infections with multidrug-resistant bacteria in a large group of German hospitals

BACKGROUND

According to extrapolations, around 35,000 patients in Germany develop hospital acquired infections (HAI) with a multidrug-resistant organism (MDRO) every year, and about 1500 of them die. Previous estimations were based on laboratory data and prevalence studies. Aim of this study was to establish the incidences of hospital acquired MDRO infections and the resulting deaths by expert review.

METHODS

Data on patients suffering from a hospital acquired MDRO infection were collected from 32 hospitals from all care levels. Records of patients with MDRO infection who died in the year 2016 underwent an onsite review by two experts to determine the impact of the infection, if any, on the cause of death.

RESULTS

A total of 714,108 in-patients were treated in 32 hospitals participating in the study. Of these patients, 1136 suffered a hospital acquired MDRO infection (1.59 per 1000 patients). 215 patients with an MDRO infection died [0.301 per 1000, (95% CI 0,261-0,341)], but only in 78 cases this was estimated as the cause of death [0.109 per 1000 patients (95% CI 0.085-0.133)].

CONCLUSION

By putting the above rates in relation to the total number of in-patients in Germany, it can be rated that around 31,052 patients per year suffer a hospital acquired MDRO infection, and 2132 patients die from it. These results from our reviewer investigation confirm earlier extrapolations.

Health Care-Associated Infections after Subarachnoid Hemorrhage

OBJECTIVE

Health care-associated infections (HAIs) after subarachnoid hemorrhage (SAH) are prevalent; however, data describing epidemiology of infection are limited. This study reports incidence rates, risk factors, and the resulting SAH patient-related outcomes.

METHODS

We studied the incidence of HAIs acquired in the intensive care unit (ICU) over a 6-year period. We used Bayesian Model Averaging to identify risk factors associated with an increased risk of HAIs, particularly urinary tract infections (UTI), pneumonia, and ventriculostomy-associated infections (VAI). We also examined the impact of HAIs on risk of vasospasm, ICU and hospital length of stay, and discharge disposition and adjusted for other risk factors.

RESULTS

Of 419 patients with SAH, 66 (15.8%) developed 79 HAI episodes. Mean HAI incidence rates (per 1000 ICU-days) were UTI, 7.1; pneumonia, 4.3; and VAI, 2.4. The admission characteristic associated with increased risk of overall HAI, UTI, and VAI was diabetes mellitus. Hunt and Hess grades III-V were associated with increased risk of overall HAI and VAI. Male gender, intraventricular hemorrhage, and blood glucose level (>10) were associated with increased risk of pneumonia, whereas the incidence was lower in the presence of steroids. HAI was associated with increased length of stay of 10 ICU-days and 22 hospital-days, but not vasospasm or poor discharge disposition.

CONCLUSIONS

HAIs are serious complications after SAH associated with prolonged ICU and hospital length of stay. Additional rigorous infection control measures aimed at patients with identifiable risk factors should trigger prevention, and early detection of nosocomial infections is warranted to further reduce the prevalence of HAIs.

[Risk management in anesthesia and critical care medicine]

Throughout its history, anesthesia and critical care medicine has experienced vast improvements to increase patient safety. Consequently, anesthesia has never been performed on such a high level as it is being performed today. As a result, we do not always fully perceive the risks involved in our daily activity. A survey performed in Swiss hospitals identified a total of 169 hot spots which endanger patient safety. It turned out that there is a complex variety of possible errors that can only be tackled through consistent implementation of a safety culture. The key elements to reduce complications are continuing staff education, algorithms and standard operating procedures (SOP), working according to the principles of crisis resource management (CRM) and last but not least the continuous work-up of mistakes identified by critical incident reporting systems.

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.

[Advantages and disadvantages of different methods for the implementation and the support of standard operating procedures: From PDF files to an app- and webbased SOP management system]

BACKGROUND

The quality assurance of care and patient safety, with increasing cost pressure and performance levels is of major importance in the high-risk and high cost area of the operating room (OR). Standard operating procedures (SOP) are an established tool for structuring and standardization of the clinical treatment pathways and show multiple benefits for quality assurance and process optimization.

OBJECTIVES

An internal project was initiated in the department of anesthesiology and a continuous improvement process was carried out to build up a comprehensive SOP library.

MATERIAL AND METHODS

In the first step the spectrum of procedures in anesthesiology was transferred to PDF-based SOPs. The further development to an app-based SOP library (Aesculapp) was due to the high resource expenditure for the administration and maintenance of the large PDF-based SOP collection and to deficits in the mobile availability. The next developmental stage, the SOP healthcare information assistant (SOPHIA) included a simplified and advanced update feature, an archive feature previously missing and notably the possibility to share the SOP library with other departments including the option to adapt each SOP to the individual situation. A survey of the personnel showed that the app-based allocation of SOPs (Aesculapp, SOPHIA) had a higher acceptance than the PDF-based developmental stage SOP form.

CONCLUSION

The SOP management system SOPHIA combines the benefits of the forerunner version Aesculapp with improved options for intradepartmental maintenance and administration of the SOPs and the possibility of an export and editing function for interinstitutional exchange of SOPs.

[Errors in medicine. Causes, impact and improvement measures to improve patient safety]

The guarantee of quality of care and patient safety is of major importance in hospitals even though increased economic pressure and work intensification are ubiquitously present. Nevertheless, adverse events still occur in 3-4 % of hospital stays and of these 25-50 % are estimated to be avoidable. The identification of possible causes of error and the development of measures for the prevention of medical errors are essential for patient safety. The implementation and continuous development of a constructive culture of error tolerance are fundamental.The origins of errors can be differentiated into systemic latent and individual active causes and components of both categories are typically involved when an error occurs. Systemic causes are, for example out of date structural environments, lack of clinical standards and low personnel density. These causes arise far away from the patient, e.g. management decisions and can remain unrecognized for a long time. Individual causes involve, e.g. confirmation bias, error of fixation and prospective memory failure. These causes have a direct impact on patient care and can result in immediate injury to patients. Stress, unclear information, complex systems and a lack of professional experience can promote individual causes. Awareness of possible causes of error is a fundamental precondition to establishing appropriate countermeasures.Error prevention should include actions directly affecting the causes of error and includes checklists and standard operating procedures (SOP) to avoid fixation and prospective memory failure and team resource management to improve communication and the generation of collective mental models. Critical incident reporting systems (CIRS) provide the opportunity to learn from previous incidents without resulting in injury to patients. Information technology (IT) support systems, such as the computerized physician order entry system, assist in the prevention of medication errors by providing information on dosage, pharmacological interactions, side effects and contraindications of medications.The major challenges for quality and risk management, for the heads of departments and the executive board is the implementation and support of the described actions and a sustained guidance of the staff involved in the modification management process. The global trigger tool is suitable for improving transparency and objectifying the frequency of medical errors.

Effect of blood-sugar limitation on intensive care mortality: Intragroup evaluation

OBJECTIVE

To evaluate the safety profile of blood sugar limits in intensive care unit (ICU) patients.

METHODS

Adult patients with ICU stay >36 h, more than two blood sugar measurements and antibiotic therapy concordant with locally adapted guidelines were included. For analyses, one study cohort was defined in two ways: as a narrow group, euglycaemic patients' blood sugar levels 80-150 mg/dl; as a moderate group, euglycaemic patients' blood sugar levels 80-180 mg/dl. Dysglycaemia was defined as blood sugar levels <80 mg/dl for >5% of measurements, and >150 mg/dl or >180 mg/dl (narrow or moderate groups, respectively) for >10% of measurements. The primary endpoint was ICU mortality (euglycaemia versus dysglycaemia).

RESULTS

The study comprised 668 patients. When defined as a narrow group, ICU mortality was 3% (four of 135) euglycaemic versus 10% (54/533) dysglycaemic patients (odds ratio [OR] 3.692, 95% confidence interval [CI] 1.313, 10.382). When defined as a moderate group, ICU mortality was 6% (21/351) euglycaemic versus 12% (37/317) dysglycaemic patients (OR 2.077, 95% CI 1.188, 3.630). Frequency of severe hypoglycaemia (blood sugar <40 mg/dl) was not different between the narrow and moderate euglycaemic ranges.

CONCLUSIONS

Euglycaemia was associated with lower ICU mortality than dysglycaemia, and incidence of hypoglycaemia was low overall in this study. Based on current published evidence, therapeutic targets should be defined according to individual patient characteristics.

Observational clinical study on the effects of different dosing regimens on vancomycin target levels in critically ill patients: Continuous versus intermittent application

Different dosing regimens for vancomycin are in clinical use: intermittent infusion and continuous administration. The intention of using these different dosing regimens is to reduce toxicity, to achieve target levels faster and to avoid treatment failure. The aim of this phase IV study was to compare safety and effectiveness in both administration regimens. The study was conducted in 2010 and 2011 in three postoperative intensive care units (ICUs) in a tertiary care university hospital in Berlin, Germany. Adult patients with vancomycin therapy and therapeutic drug monitoring were included. Out of 675 patients screened, 125 received vancomycin therapy, 39% with intermittent and 61% with continuous administration. Patients with continuous administration achieved target serum levels significantly earlier (median day 3 versus 4, p=0.022) and showed fewer sub-therapeutic serum levels (41% versus 11%, p<0.001). ICU mortality rate, duration of ICU stay and duration of ventilation did not differ between groups. Acute renal failure during the ICU stay occurred in 35% of patients with intermittent infusion versus 26% of patients with continuous application (p=0.324). In conclusion, continuous administration of vancomycin allowed more rapid achievement of targeted drug levels with fewer sub-therapeutic vancomycin levels observed. This might indicate that patients with more severe infections or higher variability in renal function could benefit from this form of administration.

Long-term effect of computer-assisted decision support for antibiotic treatment in critically ill patients: a prospective 'before/after' cohort study

OBJECTIVES

Antibiotic resistance has risen dramatically over the past years. For individual patients, adequate initial antibiotic therapy is essential for clinical outcome. Computer-assisted decision support systems (CDSSs) are advocated to support implementation of rational anti-infective treatment strategies based on guidelines. The aim of this study was to evaluate long-term effects after implementation of a CDSS.

DESIGN

This prospective 'before/after' cohort study was conducted over four observation periods within 5 years. One preinterventional period (pre) was compared with three postinterventional periods: directly after intensive implementation efforts (post1), 2 years (post2) and 3 years (post3) after implementation.

SETTING

Five anaesthesiological-managed intensive care units (ICU) (one cardiosurgical, one neurosurgical, two interdisciplinary and one intermediate care) at a university hospital.

PARTICIPANTS

Adult patients with an ICU stay of >48 h were included in the analysis. 1316 patients were included in the analysis for a total of 12,965 ICU days.

INTERVENTION

Implementation of a CDSS.

OUTCOME MEASURES

The primary end point was percentage of days with guideline adherence during ICU treatment. Secondary end points were antibiotic-free days and all-cause mortality compared for patients with low versus high guideline adherence.

MAIN RESULTS

Adherence to guidelines increased from 61% prior to implementation to 92% in post1, decreased in post2 to 76% and remained significantly higher compared with baseline in post3, with 71% (p=0.178). Additionally, antibiotic-free days increased over study periods. At all time periods, mortality for patients with low guideline adherence was higher with 12.3% versus 8% (p=0.014) and an adjusted OR of 1.56 (95% CI 1.05 to 2.31).

CONCLUSIONS

Implementation of computerised regional adapted guidelines for antibiotic therapy is paralleled with improved adherence. Even without further measures, adherence stayed high for a longer period and was paralleled by reduced antibiotic exposure. Improved guideline adherence was associated with reduced ICU mortality.

Standard operating procedures for antibiotic therapy and the occurrence of acute kidney injury: a prospective, clinical, non-interventional, observational study

Introduction

Acute kidney injury (AKI) occurs in 7% of hospitalized and 66% of Intensive Care Unit (ICU) patients. It increases mortality, hospital length of stay, and costs. The aim of this study was to investigate, whether there is an association between adherence to guidelines (standard operating procedures (SOP)) for potentially nephrotoxic antibiotics and the occurrence of AKI.

Methods

This study was carried out as a prospective, clinical, non-interventional, observational study. Data collection was performed over a total of 170 days in three ICUs at Charité – Universitaetsmedizin Berlin. A total of 675 patients were included; 163 of these had therapy with vancomycin, gentamicin, or tobramycin; were >18 years; and treated in the ICU for >24 hours. Patients with an adherence to SOP >70% were classified into the high adherence group (HAG) and patients with an adherence of <70% into the low adherence group (LAG). AKI was defined according to RIFLE criteria. Adherence to SOPs was evaluated by retrospective expert audit. Development of AKI was compared between groups with exact Chi²-test and multivariate logistic regression analysis (two-sided P <0.05).

Results

LAG consisted of 75 patients (46%) versus 88 HAG patients (54%). AKI occurred significantly more often in LAG with 36% versus 21% in HAG (P = 0.035). Basic characteristics were comparable, except an increased rate of soft tissue infections in LAG. Multivariate analysis revealed an odds ratio of 2.5-fold for LAG to develop AKI compared with HAG (95% confidence interval 1.195 to 5.124, P = 0.039).

Conclusion

Low adherence to SOPs for potentially nephrotoxic antibiotics was associated with a higher occurrence of AKI.

[Perioperative conflicts between anaesthesiologists and surgeons: ethics and professionalism]

In the perioperative period, several potential conflicts between anaesthetists/intensive care specialists and surgeons may exist. They are detrimental to the quality of patient care and to the well-being of the teams. They are a source of medical errors and contribute to burn-out. Patients can become the victims of such conflicts, which deserve ethical reflection. Their resolution through analysis and shared solutions is necessary. This article seeks to analyse these conflicts, taking into account their specificities and constraints. In order to understand this context, it is important to consider the specificities of each group involved and the records of such situations. Several factors can prevent these conflicts, first and foremost the patients themselves and the quality of the care that is provided. Medical deontology aims mainly at preventing and resolving these conflicts. Generally speaking, the quality approach which is increasingly applied in health care institutions (involving declarations of adverse events, morbidity/mortality reviews, benchmarking, analysis and improvement of practices, etc.) also contributes to the prevention and resolution of disagreements. The teaching of communication techniques that begins with the initial training, the evaluation of team behaviours (through simulation training for example), the respect of others' constraints, particularly when it comes to learning, as well as transparency regarding conflicts of interests, are all additional elements of conflict prevention. Lastly, conflicts may at times be caused by deviant behaviours, which must be met with a clear and uncompromising collective and institutional approach. This article concludes by offering a standardised approach for conflict resolution.

Value of American Thoracic Society guidelines in predicting infection or colonization with multidrug-resistant organisms in critically ill patients

Background

The incidence rate of infection by multidrug-resistant organisms (MDROs) can affect the accuracy of etiological diagnosis when using American Thoracic Society (ATS) guidelines. We determined the accuracy of the ATS guidelines in predicting infection or colonization by MDROs over 18 months at a single ICU in eastern China.

Methods

This prospective observational study examined consecutive patients who were admitted to an intensive care unit (ICU) in Nanjing, China. MDROs were defined as bacteria that were resistant to at least three antimicrobial classes, such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), Pseudomonas aeruginosa, Acinetobacter baumannii. Screening for MDROs was performed at ICU admission and discharge. Risk factors for infection or colonization with MDROs were recorded, and the accuracy of the ATS guidelines in predicting infection or colonization with MDROs was documented.

Results

There were 610 patients, 225 (37%) of whom were colonized or infected with MDROs at ICU admission, and this increased to 311 (51%) at discharge. At admission, the sensitivity (70.0%), specificity (31.6%), positive predictive value (38.2%), and negative predictive value (63.5%), all based on ATS guidelines for infection or colonization with MDROs were low. The negative predictive value was greater in patients from departments with MDRO infection rates of 31–40% than in patients from departments with MDRO infection rates of 30% or less and from departments with MDRO infection rates more than 40%.

Conclusion

ATS criteria were not reliable in predicting infection or colonization with MDROs in our ICU. The negative predictive value was greater in patients from departments with intermediate rates of MDRO infection than in patients from departments with low or high rates of MDRO infection.

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.

Immediate outcome indicators in perioperative care: a controlled intervention study on quality improvement in hospitals in Tanzania

Introduction

Outcome assessment is the standard for evaluating the quality of health services worldwide. In this study, outcome has been divided into immediate and final outcome. Aim was to compare an intervention hospital with a Continuous Quality Improvement approach to a control group using benchmark assessments of immediate outcome indicators in surgical care. Results were compared to final outcome indicators.

Method

Surgical care quality in six hospitals in Tanzania was assessed from 2006–2011, using the Hospital Performance Assessment Tool. Independent observers assessed structural, process and outcome quality using checklists based on evidence-based guidelines. The number of surgical key procedures over the benchmark of 80% was compared between the intervention hospital and the control group. Results were compared to Case Fatality Rates.

Results

In the intervention hospital, in 2006, two of nine key procedures reached the benchmark, one in 2009, and four in 2011. In the control group, one of nine key procedures reached the benchmark in 2006, one in 2009, and none in 2011. Case Fatality Rate for all in-patients in the intervention hospital was 5.5% (n = 12,530) in 2006, 3.5% (n = 21,114) in 2009 and 4.6% (n = 18,840) in 2011. In the control group it was 3.1% (n = 17,827) in 2006, 4.2% (n = 13,632) in 2009 and 3.8% (n = 17,059) in 2011.

Discussion

Results demonstrated that quality assurance improved performance levels in both groups. After the introduction of Continuous Quality Improvement, performance levels improved further in the intervention hospital while quality in the district hospital did not. Immediate outcome indicators appeared to be a better steering tool for quality improvement compared to final outcome indicators. Immediate outcome indicators revealed a need for improvement in pre- and postoperative care.

Conclusion

Quality assurance programs based on immediate outcome indicators can be effective if embedded in Continuous Quality Improvement. Nevertheless, final outcome indicators cannot be neglected.

[Patient safety in anesthesiology and intensive care medicine. Measures for improvement]

Technical improvements as well as various strategies for error detection and error prevention have made intensive care medicine and anesthesiology a safe medical specialty. Due to the introduction of "Patient safety in the ICU: the Vienna declaration" of the European Society of Intensive Care Medicine (ESICM) from October 2009 and the "Helsinki declaration on patient safety" of the European Society of Anaesthesiology (ESA) and the European Board of Anaesthesiology (EBA) from June 2010, there are now specific recommendations for all hospitals in Europe concerning the safety measures that are considered to be of essential importance. Many of today's well-known safety strategies have been originally developed in non-medical environments, as for instance civil aviation. Such high reliability organizations may serve as examples in the medical domain. Critical incident reporting systems, crisis resource management and checklists, e.g. the World Health Organization (WHO) checklist, are safety approaches of this kind. In addition to these, standardized drug labelling, hand disinfection, techniques for patient handover and simulation-based training have been exemplarily selected for this article as measures that can increase patient safety.

Early-onset ventilator-associated pneumonia in adults randomized clinical trial: comparison of 8 versus 15 days of antibiotic treatment

PURPOSE

The optimal treatment duration for ventilator-associated pneumonia is based on one study dealing with late-onset of the condition. Shortening the length of antibiotic treatment remains a major prevention factor for the emergence of multiresistant bacteria.

OBJECTIVE

To demonstrate that 2 different antibiotic treatment durations (8 versus 15 days) are equivalent in terms of clinical cure for early-onset ventilator-associated pneumonia.

METHODS

Randomized, prospective, open, multicenter trial carried out from 1998 to 2002.

MEASUREMENTS

The primary endpoint was the clinical cure rate at day 21. The mortality rate was evaluated on days 21 and 90.

RESULTS

225 patients were included in 13 centers. 191 (84.9%) patients were cured: 92 out of 109 (84.4%) in the 15 day cohort and 99 out of 116 (85.3%) in the 8 day cohort (difference = 0.9%, odds ratio = 0.929). 95% two-sided confidence intervals for difference and odds ratio were [-8.4% to 10.3%] and [0.448 to 1.928] respectively. Taking into account the limits of equivalence (10% for difference and 2.25 for odds ratio), the objective of demonstrative equivalence between the 2 treatment durations was fulfilled. Although the rate of secondary infection was greater in the 8 day than the 15 day cohort, the number of days of antibiotic treatment remained lower in the 8 day cohort. There was no difference in mortality rate between the 2 groups on days 21 and 90.

CONCLUSION

Our results suggest that an 8-day course of antibiotic therapy is safe for early-onset ventilator-associated pneumonia in intubated patients.

Association between hospital volume and network membership and an analgesia, sedation and delirium order set quality score: a cohort study

Introduction

Protocols for the delivery of analgesia, sedation and delirium care of the critically ill, mechanically ventilated patient have been shown to improve outcomes but are not uniformly used. The extent to which elements of analgesia, sedation and delirium guidelines are incorporated into order sets at hospitals across a geographic area is not known. We hypothesized that both greater hospital volume and membership in a hospital network are associated with greater adherence of order sets to sedation guidelines.

Methods

Sedation order sets from all nonfederal hospitals without pediatric designation in Washington State that provided ongoing care to mechanically ventilated patients were collected and their content systematically abstracted. Hospital data were collected from Washington State sources and interviews with ICU leadership in each hospital. An expert-validated score of order set quality was created based on the 2002 four-society guidelines. Clustered multivariable linear regression was used to assess the relationship between hospital characteristics and the order set quality score.

Results

Fifty-one Washington State hospitals met the inclusion criteria and all provided order sets. Based on expert consensus, 21 elements were included in the analgesia, sedation and delirium order set quality score. Each element was equally weighted and contributed one point to the score. Hospital order set quality scores ranged from 0 to 19 (median = 8, interquartile range 6 to 14). In multivariable analysis, a greater number of acute care days (P = 0.01) and membership in a larger hospital network (P = 0.01) were independently associated with a greater quality score.

Conclusions

Hospital volume and membership in a larger hospital network were independently associated with a higher quality score for ICU analgesia, sedation and delirium order sets. Further research is needed to determine whether greater order-set quality is associated with improved outcomes in the critically ill. The development of critical care networks might be one strategy to improve order set quality scores.

An audit of inpatient management of community-acquired pneumonia in Oman: a comparison with regional clinical guidelines

OBJECTIVE

Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality worldwide. Herein, we present the findings from an audit of CAP management at a tertiary hospital in Oman. The main objective was to evaluate the quality of care given to patients and compare it with the standards in the Gulf Cooperation Council (GCC) CAP guidelines.

METHODS

A retrospective case study of all patients admitted with CAP from June 2006 to September 2008 examined the adherence to standards for the diagnosis, investigation, and management of CAP, including the documentation of illness severity.

RESULTS

The case notes of 342 patients were reviewed. Of these, 170 patients were excluded from the study, and 172 patients met the diagnostic criteria for inclusion. A CURB-65 severity score was documented for only 4 (2.3%) patients, and a smoking history was documented for 56 (32.6%) patients. Although 17 different antibiotic regimens were used, 115 (67%) patients received co-amoxiclav and clarithromycin, which is the standard of care. Additionally, 139 (81%) patients received their first dose of antibiotics within four hours of hospital admission. There was no documentation of offering influenza or pneumococcal vaccine to high risk patients.

CONCLUSION

The clinical coding of CAP diagnosis was poor. There was very poor adherence to the CAP severity assessment and the provision of preventive measures upon hospital discharge. The development and implementation of a local hospital-based integrated care pathway may lead to more successful implementation of the guidelines.

Selective Neurogenic Blockade and Perioperative Immune Reactivity in Patients Undergoing Lung Resection

OBJECTIVE: This double-blind, prospective, randomized, controlled trial examined the effects of thoracic epidural block and intravenous clonidine and opioid treatment on the postoperative Th1/Th2 cytokine ratio after lung surgery. The primary endpoint was the interferon γ (IFN-γ; Th1 cytokine)/interleukin 4 (IL-4; Th2 cytokine) ratio. Secondary endpoints were reductions in pain and incidence of pneumonia. METHODS: Sixty patients were randomized into three groups to receive remifentanil intravenously (remifentanil group, n = 20), remifentanil and clonidine intravenously (clonidine group, n = 20), or ropivacaine epidurally (ropivacaine group, n = 20). Pain was assessed using a numerical rating scale (NRS). Cytokines were measured using a cytometric bead array. RESULTS: Patients in the ropivacaine group (thoracic epidural block) had a significantly lower IFN-γ/IL-4 ratio at the end of surgery than those in the remifentanil group and clonidine group. There were no significant between-group differences in the IFN-γ/IL-4 ratio at other time-points. There were no differences in NRS scores at any time-point. No patient developed pneumonia. CONCLUSION: Intraoperative thoracic epidural block decreased the IFN-γ/IL-4 ratio immediately after lung surgery, indicating less inflammatory stimulation during surgery.

Gender-related outcome difference is related to course of sepsis on mixed ICUs: a prospective, observational clinical study

INTRODUCTION

Impact of gender on severe infections is in highly controversial discussion with natural survival advantage of females described in animal studies but contradictory to those described human data. This study aims to describe the impact of gender on outcome in mixed intensive care units (ICUs) with a special focus on sepsis.

METHODS

We performed a prospective, observational, clinical trial at Charité University Hospital in Berlin, Germany. Over a period of 180 days, patients were screened, undergoing care in three mainly surgical ICUs. In total, 709 adults were included in the analysis, comprising the main population ([female] n = 309, [male] n = 400) including 327 as the sepsis subgroup ([female] n = 130, [male] n = 197).

RESULTS

Basic characteristics differed between genders in terms of age, lifestyle factors, comorbidities, and SOFA-score (Sequential Organ Failure Assessment). Quality and quantity of antibiotic therapy in means of antibiotic-free days, daily antibiotic use, daily costs of antibiotics, time to antibiotics, and guideline adherence did not differ between genders. ICU mortality was comparable in the main population ([female] 10.7% versus [male] 9.0%; P = 0.523), but differed significantly in sepsis patients with [female] 23.1% versus [male] 13.7% (P = 0.037). This was confirmed in multivariate regression analysis with OR = 1.966 (95% CI, 1.045 to 3.701; P = 0.036) for females compared with males.

CONCLUSIONS

No differences in patients' outcome were noted related to gender aspects in mainly surgical ICUs. However, for patients with sepsis, an increase of mortality is related to the female sex.

Overview of antimicrobial therapy in intensive care units

In the management of a patient with severe sepsis, it is important to suspect the infection early, to collect samples immediately after diagnosis and to promptly initiate a broad-spectrum antibiotic treatment. The choice of this empirical antimicrobial therapy should be based on host characteristics, site of infection, local ecology and pharmacokinetics/pharmacodynamics of antibiotics. In severe infection, guidelines recommend the use of a combination of antibiotics. After results of cultures are obtained, treatment should be re-evaluated to either de-escalate or escalate the antibiotic prescription. This is associated with optimal costs, decreased incidence of superinfection and minimal development of antimicrobial resistance. All these steps should rely on written protocols, and the compliance to these protocols should be continuously monitored in order to detect violations and implement corrective procedures.

Computer-assisted decision support for changing practice in severe sepsis and septic shock

Computer-assisted decision support systems (CDSS) are designed to improve infection management. The aim of this prospective, clinical pre- and post-intervention study was to investigate the influence of CDSS on infection management of severe sepsis and septic shock in intensive care units (ICUs). Data were collected for a total of 180 days during two study periods in 2006 and 2007. Of the 186 patients with severe sepsis or septic shock, 62 were stratified into a low adherence to infection management standards group (LAG) and 124 were stratified into a high adherence group (HAG). ICU mortality was significantly increased in LAG versus HAG patients (Kaplan-Meier analysis). Following CDSS implementation, adherence to standards increased significantly by 35%, paralleled with improved diagnostics, more antibiotic-free days and a shortened time until antibiotics were administered. In conclusion, adherence to infection standards is beneficial for patients with severe sepsis or septic shock and CDSS is a useful tool to aid adherence.

Delayed treatment of delirium increases mortality rate in intensive care unit patients

Delirium in the intensive care unit (ICU) is a serious complication associated with a poor outcome in critically ill patients. In this prospective observational study of the effect of a delay in delirium therapy on mortality rate, 418 ICU patients were regularly assessed using the Delirium Detection Score (DDS). The departmental standard required that if delirium was diagnosed (DDS >7), therapy should be started within 24 h. In total, 204 patients (48.8%) were delirious during their ICU stay. In 184 of the delirious patients (90.2%), therapy was started within 24 h; in 20 patients (9.8%), therapy was delayed. During their ICU stay, patients whose delirium treatment was delayed were more frequently mechanically ventilated, had more nosocomial infections (including pneumonia) and had a higher mortality rate than patients whose treatment was not delayed. Thus, it would appear that a delay in initiating delirium therapy in ICU patients was associated with increased mortality.

Surgical intensive care unit - essential for good outcome in major abdominal surgery?

PURPOSE

Surgical intensive care units (ICU) play a pivotal role in perioperative care of patients undergoing major abdominal surgery. Differences in quality of care provided by medical staff in ICUs may be linked to improved outcome. This review aims to elucidate the relationship between quality of care at various ICUs and patient outcome, with the ultimate aim of identifying key measures for achieving optimal outcome.

METHODS

We reviewed the literature in PubMed to identify current ICU structural and process concepts and variations before evaluating their respective impact on quality of care and outcome in major abdominal surgery.

RESULTS

ICU leadership, nurse and physician staffing, and provision of an intermediate care unit are important structural components that impact on patients' outcome. A "mixed ICU" model, with intensivists primarily caring for the patients in close cooperation with the primary physician, seems to be the most effective ICU model. Surgeons' involvement in intensive care is essential, and a close cooperation between surgeons and anesthesiologists is vital for good outcome. Current general process concepts include early mobilization, enteral feeding, and optimal perioperative fluid management. To decrease failure-to-rescue rates, procedure-specific intensive care processes are particularly focused on the early detection, assessment, and timely and consistent treatment of complications.

CONCLUSIONS

Several structures and processes in the ICU have an impact on outcome in major abdominal surgery. ICU structures and care processes connected with optimal outcome could be transmitted to other centers to improve outcome, independent of procedure volume.

Current challenges in the management of the infected patient

PURPOSE OF REVIEW

Management of hospital-associated infections (HAIs) has been made more challenging by the increasing proportion of immunocompromised or otherwise severely ill patients and increasing prevalence of antibiotic-resistant pathogens in this environment. This review examines strategies to optimize clinical outcomes and lower healthcare costs for patients with HAIs by focusing on patient-related, pathogen-related, and drug-related factors.

RECENT FINDINGS

Factors have converged to increase the risk of infection with antibiotic-resistant pathogens in the current hospital environment, including the increasing prevalence of resistant species and number of hospitalized patients with conditions increasingly susceptible to infection with drug-resistant bacteria. Although the list of bacterial pathogens associated with HAIs has been fairly constant over time, the prevalence and resistance profile of these individual species continues to evolve. Periodic antibiograms should be utilized to access local patterns of resistance within the different hospital wards. Outcomes for patients with HAIs are optimized with early empiric treatment with an appropriate regimen, selected on the basis of patient characteristics and local resistance patterns. Dosing strategies should be utilized to ensure that the efficacy of an appropriate antibiotic is optimized, by achieving the pharmacodynamic target predictive of its efficacy. Using these strategies improves quality of care and is associated with lower overall healthcare costs.

SUMMARY

Bacterial resistance is an increasing problem in the hospital environment, and has been associated with poorer clinical outcomes and elevated healthcare costs. By using patient characteristics, local antibiograms, and dosing strategies to achieve an optimal pharmacodynamic profile, early appropriate empiric therapy can be utilized to improve clinical outcomes, minimize the development of resistance, and reduce healthcare costs.

Development and implementation of a performance improvement project in adult intensive care units: overview of the Improving Medicine Through Pathway Assessment of Critical Therapy in Hospital-Acquired Pneumonia (IMPACT-HAP) study

INTRODUCTION

In 2005 the American Thoracic Society and Infectious Diseases Society of America (ATS/IDSA) published guidelines for managing hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP), and healthcare-associated pneumonia (HCAP). Although recommendations were evidence based, collective guidelines had not been validated in clinical practice and did not provide specific tools for local implementation. We initiated a performance improvement project designated Improving Medicine Through Pathway Assessment of Critical Therapy in Hospital-Acquired Pneumonia (IMPACT-HAP) at four academic centers in the United States. Our objectives were to develop and implement the project, and to assess compliance with quality indicators in adults admitted to intensive care units (ICUs) with HAP, VAP, or HCAP.

METHODS

The project was conducted in three phases over 18 consecutive months beginning 1 February 2006: 1) a three-month planning period for literature review to create the consensus pathway for managing nosocomial pneumonia in these ICUs, a data collection form, quality performance indicators, and internet-based repository; 2) a six-month implementation period for customizing ATS/IDSA guidelines into center-specific guidelines via educational forums; and 3) a nine-month post-implementation period for continuing education and data collection. Data from the first two phases were combined (pre-implementation period) and compared with data from the post-implementation period.

RESULTS

We developed a consensus pathway based on ATS/IDSA guidelines and customized it at the local level to accommodate formulary and microbiologic considerations. We implemented multimodal educational activities to teach ICU staff about the guidelines and continued education throughout post-implementation. We registered 432 patients (pre- vs post-implementation, 274 vs 158). Diagnostic criteria for nosocomial pneumonia were more likely to be met during post-implementation (247/257 (96.1%) vs 150/151 (99.3%); P = 0.06). Similarly, empiric antibiotics were more likely to be compliant with ATS/IDSA guidelines during post-implementation (79/257 (30.7%) vs 66/151 (43.7%); P = 0.01), an effect that was sustained over quarterly intervals (P = 0.0008). Between-period differences in compliance with obtaining cultures and use of de-escalation were not statistically significant.

CONCLUSIONS

Developing a multi-center performance improvement project to operationalize ATS/IDSA guidelines for HAP, VAP, and HCAP is feasible with local consensus pathway directives for implementation and with quality indicators for monitoring compliance with guidelines.

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).

Managing antimicrobial resistance in intensive care units

The challenges in managing patients with infection in the intensive care unit are increased in an era where there are dwindling antimicrobial choices for multidrug-resistant pathogens. Clinicians in the intensive care unit must balance between choosing appropriate antimicrobial treatment for patients with suspected infection and utilizing antimicrobials in a judicious fashion. Improving antimicrobial utilization is a critical component to reducing antimicrobial resistance. Although providing effective antimicrobial therapy and improving antimicrobial utilization may seem to be competing goals, there are effective strategies to accomplish both. Antimicrobial stewardship programs provide an organized way to implement these strategies and can enhance the intensive care unit physician's success in improving patient outcomes and combating antimicrobial resistance in the intensive care unit.

Perioperative management of patients with alcohol, tobacco and drug dependency

PURPOSE OF REVIEW

One in five patients in the perioperative setting has a alcohol use disorder (AUD), one in three patients has a nicotine use disorder (NUD) and one in 10 patients has a drug use disorder (DUD) with a high risk of dependency. Patients with dependencies challenge physicians with various complications within the perioperative setting.

RECENT FINDINGS

Adequate treatment of alcohol, nicotine and drug dependency during the perioperative and intraoperative course requires established screening tools in order to evaluate patients' susceptibility to developing complications. Particularly in these patients, secondary prevention and early treatment is warranted.

SUMMARY

Alcohol, nicotine and drug dependency are very treatable. Numerous effective therapeutic options are available and should be offered to patients. Intensive care treatment can be shortened or even avoided by initiating preventive measures. A multimodal approach includes implementation of screening tools, motivational interviewing, preoperative abstinence, individual anaesthesiological treatment, stress reduction preventing delirium and postoperative infection, prevention and treatment of withdrawal syndrome, replacement therapies and provision of preoperative or postoperative detoxification. The implementation rate is very low and urgently requires strategies for improvement.

Severe hospital-acquired pneumonia: a review for clinicians

Hospital-acquired pneumonia (HAP) is one of the most commonly encountered nosocomial infections. Patients who develop severe HAP experience considerable morbidity and mortality, and the condition results in a substantial expenditure of health care resources. A large body of scientific literature about HAP now exists. This article summarizes the current state of knowledge concerning severe HAP with an emphasis on recent advances in its diagnosis, treatment, and prevention.

Do guidelines change outcomes in ventilator-associated pneumonia?

PURPOSE OF REVIEW

The purpose of the study is to summarize effects of implementation of current and past guidelines for management and treatment of ventilator-associated pneumonia (VAP) on outcome of intensive care patients, with particular focus on etiology of VAP, pathogens prediction, appropriate empiric antibiotic therapy and mortality.

RECENT FINDINGS

Several studies have shown that in patients with clinical suspicion of VAP, appropriate antibiotic therapy administered in a timely manner can improve survival. Guidelines for management and treatment of VAP have been developed to help physicians to achieve those goals. Implementation of guidelines into clinical practice is difficult to achieve and requires extensive education for healthcare personnel and translation of recommendations into local protocols. Studies have shown that guidelines implementation is associated with better outcome. However, extensive research needs to be undertaken in order to validate efficacy of guidelines in predicting etiology of pneumonia, in particular, to promptly identify multidrug-resistant pathogens. Only one recent report has validated the latest guidelines and called attention for further research to improve microbial prediction.

SUMMARY

Guidelines implementation can improve outcomes. To achieve this goal, guidelines should be adapted to local microbiology, accurately predict VAP pathogens and help physicians to administer the most appropriate empirical antimicrobial therapy.
