Purpose: To analyze the feasibility of eye‐tracking (ET) devices as a communicative approach to the basic needs (BN) of intensive care unit (ICU) and invasively ventilated nonverbal patients. Methods: Prospective, monocentric, and observational study including all patients without delirium, with an endotracheal tube or tracheostomy tube, with a history of invasive ventilation for more than 48 h, and inadequate nonverbal communication skills. The investigation was performed with commercially available ET devices (Tobii Dynavox I‐15+) to express BN of ICU patients following a standardized 30‐item yes‐or‐no questionnaire. Results: A total of 64 patients with a mean age of 58.6 years were included. The main diagnoses for ICU admission were major trauma (43.6%), sepsis (21.8%), and acute abdomen (15.6%). Pain during repositioning (69%), thirst (69%), sleep disorders (66%), fatigue (64%), and anxiety regarding the lifelong need for assistance (64%) were the main problems reported by the patients. However, most of the patients described expectations of health improvement (78%), good family support (66%), and an improvement in quality of life due to the use of ET devices (67%). Conclusion: The use of ET in selected ICU patients with impaired communication is feasible, allowing them to express their BN. Apart from knowing the patients' individual BN, the results of our BN questionnaire may provide guidance for improvement measures in the care of patients in the ICU who are unable to speak. We believe that ET is useful for inquiring about and expressing BN and, therefore, may be capable of improving patient‐medical team interactions and patient satisfaction. [ABSTRACT FROM AUTHOR]

ABO blood group has a profound influence on hemostasis as it is a major determinant of plasma levels of von Willebrand Factor. In vitro studies suggest that blood group O is a risk factor for increased severe bleeding while blood group non-O is a risk factor for thromboembolic events. Yet, the impact of ABO blood group outcome after multiple trauma is unknown. Retrospective multicenter case-control study from three level-1 trauma centers in Germany from 2012-2015. Inclusion criteria were severe trauma with an Injury severity score =9 and admission to an intensive care unit. 1281 patients (69.5% male) were included. Mean Injury Severity Score (ISS) was 21.1±12.4; mean age was 50.2±22.4 years. Distribution of blood groups was: O: 37.4%; A: 44%, B: 12.7 and AB: 5.8%. Hospital mortality depending on blood group was 9.7 (A), 10.4 (B), 6.8 (AB) and 12.7 (O) %. Multivariant logistic regression for mortality revealed an Odds ratio of 0.79 (A), 0.60 (B) and 0.54 (AB) without statistical significance (P=0.35 (A), 0.17 (B), 0.33 (AB)). Thromboembolic events (blood group O vs. others) occurred in 2.8 (O) vs. 3.3 (others) %, P=0.619. In this retrospective study on 1281 multiple injured patients, no relevant influence of ABO blood group on hemorrhage, thromboembolic events and mortality could be found. [ABSTRACT FROM AUTHOR]

Background: Ankylosing spondylitis (AS) is a common disease with an incidence of approximately 0.5% in Europe, causing severe limitations of axial spine mobility and cervical kyphosis. Deformities of the cervical spine and the temporomandibular joints could increase the risk of complications while performing an intubation or tracheostomy. The percutaneous dilatational tracheostomy (PDT) is a standard procedure in intensive care medicine. However, the combination of cervical kyphosis and osteoporosis makes patient positioning challenging. Therefore, one could conclude that patients with AS are not candidates for PDT, but neither studies nor case reports yet reported about feasibility of this procedure in AS. Methods: Retrospective analysis at a level 1 trauma center of patient records from 2002 to 2016, assessing all patients with AS and PDT. Results: A total of 31 patients with AS have been subjected to PDT. All PDTs were performed using the modified Ciaglia single-step dilatational technique. Neither cardiopulmonary nor surgical complications occurred during the procedure. One patient received a change of the existing airway prior to the procedure; a small nasal tube was changed for a laryngeal mask. Conclusion: Although head positioning may be challenging, PDT should be taken into consideration for patients with AS. In the hands of an experienced doctor, it is safe and feasible.

We totally agree with Deana and Colleagues that missing intermediate care 1) might be an explanation for unexpected unfavorable outcome and 2) strengthening of intermediate care has the potential to lower this high rate of unfavorable outcome after ICU discharge. Yes- mind the gap! [ABSTRACT FROM AUTHOR]

Background: Most trauma patients admitted to the hospital alive and die later on, decease during the initial care in the emergency department or the intensive care unit (ICU). However, a number of patients pass away after having been discharged from the ICU during the initial hospital stay. On first sight these cases could be seen as "failure to rescue" of potentially salvageable patients. A low rate of such patients might be a potential indicator of quality for trauma care on ICUs and surgical wards. Methods: Retrospective analysis of the TraumaRegister DGU® with data from 2015 to 2017. Patients that died during the initial ICU stay were compared to those who were discharged from the initial ICU stay for at least 24 h but died later on. Results: A total of 82,313 trauma patients were included in the TraumaRegister DGU®. In total, 6576 patients (8.0%) died during their hospital stay. Out of those, 5481 were admitted to the ICU alive and 972 patients (17.7%) were discharged from ICU and died later on. Those were older (mean age: 77 vs. 68 years), less severely injured (mean ISS: 23.1 vs. 30.0 points) and had a longer mean ICU length of stay (10 vs. 6 days). A limitation of life-sustaining therapy due to a documented living will was present in 46.1% of all patients who died during their initial ICU stay and in 59.9% of patients who died after discharge from their initial ICU stay. Conclusions: 17.7% of all non-surviving severely injured trauma patients died within the hospital after discharge from their initial ICU treatment. Their death can partially be explained by a limitation of therapy due to a living will. In conclusion, the rate of such late deaths may partially represent patients that died of potentially avoidable or treatable complications. [ABSTRACT FROM AUTHOR]

A scientific panel was created consisting of 23 interdisciplinary and interprofessional experts in intensive care medicine, physiotherapy, nursing care, surgery, rehabilitative medicine, and pneumology delegated from scientific societies together with a patient representative and a delegate from the Association of the Scientific Medical Societies who advised methodological implementation. The guideline was created according to the German Association of the Scientific Medical Societies (AWMF), based on The Appraisal of Guidelines for Research and Evaluation (AGREE) II. The topics of (early) mobilisation, neuromuscular electrical stimulation, assist devices for mobilisation, and positioning, including prone positioning, were identified as areas to be addressed and assigned to specialist expert groups, taking conflicts of interest into account. The panel formulated PICO questions (addressing the population, intervention, comparison or control group as well as the resulting outcomes), conducted a systematic literature review with abstract screening and full-text analysis and created summary tables. This was followed by grading the evidence according to the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence and a risk of bias assessment. The recommendations were finalized according to GRADE and voted using an online Delphi process followed by a final hybrid consensus conference. The German long version of the guideline was approved by the professional associations. For this English version an update of the systematic review was conducted until April 2024 and recommendation adapted based on new evidence in systematic reviews and randomized controlled trials. In total, 46 recommendations were developed and research gaps addressed. [ABSTRACT FROM AUTHOR]

Background: Oxygen (O2) is a drug with specific biochemical and physiological properties, a range of effective doses and may have side effects. In 2015, 14% of over 55,000 hospital patients in the UK were using oxygen. 42% of patients received this supplemental oxygen without a valid prescription. Health care professionals are frequently uncertain about the relevance of hypoxemia and have low awareness about the risks of hyperoxemia. Numerous randomized controlled trials about targets of oxygen therapy have been published in recent years. A national guideline is urgently needed. Methods: A national S3 guideline was developed and published within the Program for National Disease Management Guidelines (AWMF) with participation of 10 medical associations. A literature search was performed until February 1, 2021, to answer 10 key questions. The Oxford Centre for Evidence-Based Medicine (CEBM) System ("The Oxford 2011 Levels of Evidence") was used to classify types of studies in terms of validity. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) was used for assessing the quality of evidence and for grading guideline recommendation, and a formal consensus-building process was performed. Results: The guideline includes 34 evidence-based recommendations about indications, prescription, monitoring and discontinuation of oxygen therapy in acute care. The main indication for O2 therapy is hypoxemia. In acute care both hypoxemia and hyperoxemia should be avoided. Hyperoxemia also seems to be associated with increased mortality, especially in patients with hypercapnia. The guideline provides recommended target oxygen saturation for acute medicine without differentiating between diagnoses. Target ranges for oxygen saturation are based depending on ventilation status risk for hypercapnia. The guideline provides an overview of available oxygen delivery systems and includes recommendations for their selection based on patient safety and comfort. Conclusion: This is the first national guideline on the use of oxygen in acute care. It addresses health care professionals using oxygen in acute out-of-hospital and in-hospital settings.

Background: The evaluation of pain in patients, unable of oral communication, often relies on behavioral assessment. However, some critically ill patients, while non-verbal, are awake and have some potential for self-reporting. The objective was to compare the results of a behavioral pain assessment with self-reporting in awake, non-verbal, critically ill patients unable to use low-tech augmentative and alternative communication tools. Methods: Prospective cohort study of intubated or tracheotomized adult, ventilated patients with a RASS (Richmond Agitation Sedation Scale) of -1 to + 1 and inadequate non-verbal communication skills in a surgical intensive care unit of a tertiary care university hospital. For pain assessment, the Behavioral Pain Scale (BPS) was used. Self-reporting of pain was achieved by using an eye tracking device to evaluate the Numeric Rating Scale (NRS) and the pain/discomfort item of the EuroQol EQ-5D-5 L (EQ-Pain). All measurements were taken at rest. Results: Data was collected from 75 patients. Neither the NRS nor the EQ-Pain (r <.15) correlated with the BPS. However, NRS and EQ-Pain were significantly correlated (r =.78, p = < 0.001), indicating the reliability of the self-reporting by these patients. Neither the duration of intubation/tracheostomy, nor cause for ICU treatment, nor BPS subcategories had an influence on these results. Conclusions: Behavioral pain assessment tools in non-verbal patients who are awake and not in delirium appear unreliable in estimating pain during rest. Before a behavioral assessment tool such as the BPS is used, the application of high-tech AACs should be strongly considered.

Eye-tracking (ET) may be a novel tool for communication with intubated and mechanically ventilated critically ill patients. We hypothesized that ET could be learned fast and be used successfully by intensive care unit (ICU) and intermediate care (IMC) patients with artificial airways for communication. Including all patients with mechanical ventilation via oral intubation or tracheostomy, who were at least 18 years of age with a score of −1 to +1 points on the Richmond agitation-sedation scale and a history of ventilation for more than 48 h. A commercially available ET was used. The investigations were performed by a physician with the support of a psychologist following a standardized study protocol. During a 4-week period a total of 11 patients completed all of the five steps of our study protocol. The time to complete our study protocol was 64 ± 23.8 min (range 43–125 min) with a mean of 1.5 ± 0.9 sessions (range 1–4 sessions). Seven patients (63.6 %) could run through all of the five steps within their first session. All patients (100%) preferred the gaze fixation technique to control the ET to the wink control. Mechanically ventilated ICU and IMC patients are able to use ET in a very short time for communication to indicate their basic needs, answer rating scales and pain scores as well as questionnaires about quality of life and self-esteem. COMFORT - The novel communication device improves the patients' ability to communicate with the attending physicians, physiotherapists and nurses in order to provide a tailored rehabilitation approach. COMPLIANCE - The use of the eye-tracking technology enables the patients to communicate special needs and fears during the course of the rehabilitation. COMPLICATIONS - The eye-tracking technology enables the attending rehabilitation team to earlier detect complications (e.g. pain, depression) during the course of the rehabilitation.

Background: The aim of this survey was to describe, on a patient basis, the current practice of sedation, pharmacologic and non-pharmacologic measures to promote sleep and facilitation of communication in critically ill patients oro-tracheally intubated or tracheostomized. Methods: Cross-sectional online-survey evaluating sedation, sleep management and communication in oro-tracheally intubated (IP) or tracheostomized (TP) patients in intensive care units on a single point. Results: Eighty-one intensive care units including 447 patients (IP: n = 320, TP: n = 127) participated. A score of ≤ -2 on the Richmond Agitation Sedation Scale (RASS) was prevalent in 58.2% (IP 70.7% vs. TP 26.8%). RASS -1/0 was present in 32.2% (IP 25.9% vs. TP 55.1%) of subjects. Propofol and alpha-2-agonist were the predominant sedatives used while benzodiazepines were applied in only 12.1% of patients. For sleep management, ear plugs and sleeping masks were rarely used (< 7%). In half of the participating intensive care units a technique for phonation was used in the tracheostomized patients. Conclusions: The overall rate of moderate and deep sedation appears high, particularly in oro-tracheally intubated patients. There is no uniform sleep management and ear plugs and sleeping masks are only rarely applied. The application of phonation techniques in tracheostomized patients during assisted breathing is low. More efforts should be directed towards improved guideline implementation. The enhancement of sleep promotion and communication techniques in non-verbal critically ill patients may be a focus of future guideline development. [ABSTRACT FROM AUTHOR]

Background: Although the use of vasopressors to maintain haemodynamic goals after acute spinal cord injury (SCI) is still recommended, evidence regarding the target values and possible risks of this practice is limited, and data on haemodynamic parameters unaffected by catecholamines are rare. In this pilot study, we show the haemodynamic profile of patients with acute SCI mainly unaffected by vasopressor use and other factors that influence the cardiovascular system. Methods: From March 2018 to March 2020, we conducted a prospective, single-centre pilot study of 30 patients with acute SCI. Factors that could affect the cardiocirculatory system other than SCI (sepsis, pre-existing heart disease or multiple trauma) led to exclusion. A total of 417 measurements were performed using the PiCCO™ system. Results: The mean systemic vascular resistance index (SVRI, 1447.23 ± 324.71 dyn*s*cm−5*m2), mean central venous pressure (CVP, 10.69 ± 3.16) and mean global end-diastolic volume index (GEDVI, 801.79 ± 158.95 ml/m2) deviated from the reference range, while the mean cardiac index (CI), mean stroke volume index (SVI), mean arterial pressure (MAP), and mean heart rate (HR) were within the reference range, as indicated in the literature. A mixed model analysis showed a significant negative relationship between norepinephrine treatment and MAP (83.97 vs. 73.69 mmHg, p < 0.001), SVRI (1463.40 vs. 1332.14 dyn*s*cm−5*m2, p = 0.001) and GEDVI (808.89 vs. 759.39 ml/m2, p = 0.001). Conclusion: These findings could lead to an adaptation of the target range for SVRI and MAP in patients with acute SCI and therefore reduce the use of vasopressors. [ABSTRACT FROM AUTHOR]

Background and Study Aims Patients with large intracerebral hematomas (ICH) may demonstrate different demographics and underlying brain and systemic diseases, as well as different radiologic courses and distinct outcomes. It remains unclear whether their different behavior attributes to a different biology of the ICH or to the asymmetric characteristics of the two populations. To analyze and adjust for potential sources of selection and treatment bias, our study compared age-matched patients with traumatic and nontraumatic ICH in a single cohort diagnosed and treated in the same surgical department. Material and Methods We analyzed 135 consecutive patients with traumatic (n = 90) or spontaneous ICH (n = 45) undergoing treatment at a surgical intensive care unit of an urban university hospital. We documented their differences before and after adjustment for age in terms of demographics, the therapies applied, their radiologic (i.e., volume and rate of ICH expansion [HE]) and clinical (patients' outcome at 30 days) course, the length of hospital and ICU stay, as well as the hospital costs. Results Patients with traumatic ICH demonstrated more favorable clinical and radiologic characteristics at admission, that is, higher Glasgow Coma Scale score (p < 0.001), less frequently dilated pupil (p = 0.028), lower Charlson Comorbidity Index (p < 0.001), smaller ICH volume (p < 0.001), noneloquent (p < 0.001) or nonintraventricular (p = 0.003) ICH locations, as well as underwent fewer neurosurgical interventions (p < 0.001) and showed a better outcome (p = 0.041), defined as Glasgow Outcome Scale 4 and 5. After adjustment for age, no different outcomes were observed. Of note, elderly patients on novel oral anticoagulants (NOACs) were more likely to develop an HE compared with those on vitamin K antagonists (VKAs, p = 0.05) after traumatic brain injury (TBI) but not after spontaneous ICH. Conclusion Our data reveal a significant heterogeneity within the traumatic series. Whereas younger patients show an excellent outcome, the elderly population of the traumatic cases demonstrates a poor outcome similar to that of the nontraumatic cohort. HE under NOACs rather than under VKAs is more likely in the elderly after TBI. Larger prospective trials are warranted to elucidate the potential individual underlying molecular mechanisms for the development of an ICH and HE in these diseases. [ABSTRACT FROM AUTHOR]

Introduction: Prosthetic joint infection (PJI) is a severe complication after total joint replacement surgery. The current study analyzes the outcome and mortality of patients admitted to an intensive care unit following PJI. Methods: Retrospective analysis of all patients treated between 2012 and 2016 due to PJI in the surgical intensive care unit of a university hospital. Results: A total of 124 patients were included. The mean age was 75 ± 11 years. Of those 124 patients, 85 patients (68.5%) suffered a prosthetic infection of the hip, 33 patients (27.3%) of the knee, six patients (4.8%) of hip and knee. 52 patients were male (40.9%). The assessed mean Simplified Acute Physiology Score II (SAPSII) was 29.6 ± 5.9. The mortality rate was 21% (26/124). Of surviving patients, 53.1% were discharged home, 25.5% were transferred to a nursing home, and 21.4% were transferred to a geriatric rehabilitation center. Comparing survivors to non-survivors, the non-survivor group showed a higher incidence of renal replacement therapy (46.1 vs 3.0%; p < 0.01), higher SAPSII on admission (35.7 vs. 29.0; p = 0.01) and higher Charlson Comorbidity Indices (CCI) (5.5 vs. 2.82; p < 0.01). The multivariate regression identified CCI (odds ratio 1.49; p < 0.01) and renal replacement therapy (odds ratio 12.4; p < 0.01) as independent risk factors for increased mortality. Conclusions: Admission to an intensive care unit was associated with a mortality rate of 21%. Factors associated with poor outcomes included renal replacement therapy, higher admission SAPII scores, and higher admission Charlson comorbidity index. These factors could be used for individual risk assessment on admission to the ICU. [ABSTRACT FROM AUTHOR]

Little is known about patients with Periprosthetic Joint Infection (PJI) admitted to the Intensive Care Unit (ICU). The purpose of this study was threefold: i) To report the microbiological findings of ICUpatients with PJI. ii) To compare the clinical data between Difficult-To-Treat (DTT) and non-DTT PJI. iii) To identify risk factors for mortality. This is a retrospective study from a tertiary healthcare center in Germany from 2012-2016. A total of 124 patients with 169 pathogens were included. The most common bacteria were Staphyloccous aureus (26.6%), Staphyloccus epidermidis (12.4%), Enterococci ssp. and Escherichia coli (respectively 9.4%). DTT PJI was diagnosed in 28 patients (22.6%). The main pathogens of DTT PJI were Staphylococus epidermidis (14.5%), Escherichia coli (12.7%), Staphylococcus aureus and Candida spp. (respectively 9.1%). Polymicrobial PJI, number of pathogens, ICU stay and mortality were significantly differrent between DTT PJI and non-DTT PJI (p=0.05). Multivariate logistic regression identified prolonged ICU stay and DTT PJI as risk factors for mortality. In conclusion, we suggest, that the term of DTT pathogens is useful for the intensivist to assess the clinical outcome in ICU-patients with PJI. [ABSTRACT FROM AUTHOR]

Background: Even though surgical techniques and implants have evolved, periprosthetic joint infection (PJI) remains a serious complication leading to poor postoperative outcome and a high mortality. The literature is lacking in studies reporting the mortality of very elderly patients with periprosthetic joint infections, especially in cases when an intensive care unit (ICU) treatment was necessary. We therefore present the first study analyzing patients with an age 80 and higher suffering from a periprosthetic joint infection who had to be admitted to the ICU.Methods: All patients aged 80 and higher who suffered from a PJI (acute and chronic) after THR or TKR and who have been admitted to the ICU have been included in this retrospective, observational, single-center study.Results: A total of 57 patients met the inclusion criteria. The cohort consisted of 24 males and 33 females with a mean age of 84.49 (± 4.0) years. The mean SAPS II score was 27.05 (± 15.7), the mean CCI was 3.35 (± 2.28) and the most patient had an ASA score of 3 or higher. The PJI was located at the hip in 71.9% or at the knee in 24.6%. Two patients (3.5%) suffered from a PJI at both locations. Sixteen patients did not survive the ICU stay. Non-survivors showed significantly higher CCI (4.94 vs. 2.73; p = 0.02), higher SAPS II score (34.06 vs. 24.32; p = 0.03), significant more patients who underwent an invasive ventilation (132.7 vs. 28.1; p = 0.006) and significantly more patients who needed RRT (4.9% vs. 50%; p < 0.001). In multivariate analysis, RRT (odds ratio (OR) 15.4, CI 1.69-140.85; p = 0.015), invasive ventilation (OR 9.6, CI 1.28-71.9; p = 0.028) and CCI (OR 1.5, CI 1.004-2.12; p = 0.048) were independent risk factors for mortality.Conclusion: Very elderly patients with PJI who needs to be admitted to the ICU are at risk to suffer from a poor outcome. Several risk factors including a chronic infection, high SAPS II Score, high CCI, invasive ventilation and RRT might be associated with a poor outcome. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the functional outcome after lumbopelvic fixation (LPF) using the SMFA (short musculoskeletal functional assessment) score and discuss the results in the context of the existing literature. The last consecutive 50 patients who underwent a LPF from January 1st 2011 to December 31st 2014 were identified and administered the SMFA-questionnaire. Inclusion criteria were: (1) patient underwent LPF at our institution, (2) complete medical records, (3) minimum follow-up of 12 months. Out of the 50 recipients, 22 questionnaires were returned. Five questionnaires were incomplete and therefore seventeen were included for analysis. The mean age was 60.3 years (32–86 years; 9m/8f) and the follow-up averaged 26.9 months (14–48 months). Six patients (35.3%) suffered from a low-energy trauma and 11 patients (64.7%) suffered a high-energy trauma. Patients in the low-energy group were significantly older compared to patients in the high-energy group (72.2 vs. 53.8 years; p = 0.030). Five patients (29.4%) suffered from multiple injuries. Compared to patients with low-energy trauma, patients suffering from high-energy trauma showed significantly lower scores in "daily activities" (89.6 vs. 57.1; p = 0.031), "mobility" (84.7 vs. 45.5; p = 0.015) and "function" (74.9 vs. 43.4; p = 0.020). Our results suggest that patients with older age and those with concomitant injuries show a greater impairment according to the SMFA score. Even though mostly favorable functional outcomes were reported throughout the literature, patients still show some level of impairment and do not reach normative data at final follow-up.
