Interventions to Improve Hand Hygiene Compliance in the ICU: A Systematic Review
Lydon, S et al
Critical Care Medicine: November 2017 - Volume 45 - Issue 11 - p e1165–e1172
Objectives: To synthesize the literature describing interventions to improve hand hygiene in ICUs, to evaluate the quality of the extant research, and to outline the type, and efficacy, of interventions described.
Data Sources: Systematic searches were conducted in November 2016 using five electronic databases: Medline, CINAHL, PsycInfo, Embase, and Web of Science. Additionally, the reference lists of included studies and existing review papers were screened.
Study Selection: English language, peer-reviewed studies that evaluated an intervention to improve hand hygiene in an adult ICU setting, and reported hand hygiene compliance rates collected via observation, were included.
Data Extraction: Data were extracted on the setting, participant characteristics, experimental design, hand hygiene measurement, intervention characteristics, and outcomes. Interventional components were categorized using the Behavior Change Wheel. Methodological quality was examined using the Downs and Black Checklist.
Data Synthesis: Thirty-eight studies were included. The methodological quality of studies was poor, with studies scoring a mean of 8.6 of 24 (SD= 2.7). Over 90% of studies implemented a bundled intervention. The most frequently employed interventional strategies were education (78.9%), enablement (71.1%), training (68.4%), environmental restructuring (65.8%), and persuasion (65.8%). Intervention outcomes were variable, with a mean relative percentage change of 94.7% (SD= 195.7; range, 4.3–1155.4%) from pre to post intervention.
Conclusions: This review demonstrates that best practice for improving hand hygiene in ICUs remains unestablished. Future research employing rigorous experimental designs, careful statistical analysis, and clearly described interventions is important.

Advanced Percutaneous Mechanical Circulatory Support Devices for Cardiogenic Shock
Advanced Percutaneous Mechanical Circulatory Support Devices for Cardiogenic Shock
Miller, P. et al
Critical Care Medicine: November 2017 - Volume 45 - Issue 11 - p 1922–1929
To review temporary percutaneous mechanical circulatory support devices for the treatment of cardiogenic shock, including current evidence, contraindications, complications, and future directions. Data Sources: A MEDLINE search was conducted with MeSH terms: cardiogenic shock, percutaneous mechanical circulatory support, extracorporeal membrane oxygenation, Impella, and TandemHeart.
Study Selection: Selected publications included randomized controlled trial data and observational studies describing experience with percutaneous mechanical circulatory support in cardiogenic shock.
Data Extraction: Studies were chosen based on strength of association with and relevance to cardiogenic shock.
Data Synthesis: Until recently, there were few options if cardiogenic shock was refractory to vasopressors or intra-aortic balloon pump counterpulsation. Now, several percutaneous mechanical circulatory support devices, including Impella (Abiomed, Danvers, MA), TandemHeart (CardiacAssist, Pittsburgh, PA), and extracorporeal membrane oxygenation, are more accessible. Compared with intra-aortic balloon pump, Impella provides greater hemodynamic support but no reduction in mortality. Similarly, TandemHeart improves hemodynamic variables but not survival. Comparative studies have been underpowered for mortality because of small sample size. Veno-arterial extracorporeal membrane oxygenation offers the advantage of biventricular circulatory support and oxygenation, but there are significant vascular complications. Comparative studies with extracorporeal membrane oxygenation have not been completed. Despite lack of randomized controlled data, there has been a substantial increase in use of percutaneous mechanical circulatory support. Several ongoing prospective studies with larger sample sizes may provide answers, and newer devices may become smaller, easier to insert, and more effective. Conclusions: Mortality from cardiogenic shock remains unacceptably high despite early coronary revascularization or other therapies. Although evidence is lacking and complications rates are high, improvements and experience with percutaneous mechanical circulatory support may offer the prospect of better outcomes.

Brain Oxygen Optimization in Severe Traumatic Brain Injury Phase-II: A Phase II Randomized Trial
Brain Oxygen Optimization in Severe Traumatic Brain Injury Phase-II: A Phase II Randomized Trial
Okonkwo, D et al
Critical Care Medicine: November 2017 - Volume 45 - Issue 11 - p 1907–1914
Objectives: A relationship between reduced brain tissue oxygenation and poor outcome following severe traumatic brain injury has been reported in observational studies. We designed a Phase II trial to assess whether a neurocritical care management protocol could improve brain tissue oxygenation levels in patients with severe traumatic brain injury and the feasibility of a Phase III efficacy study. Design: Randomized prospective clinical trial. Setting: Ten ICUs in the United States. Patients: One hundred nineteen severe traumatic brain injury patients. Interventions: Patients were randomized to treatment protocol based on intracranial pressure plus brain tissue oxygenation monitoring versus intracranial pressure monitoring alone. Brain tissue oxygenation data were recorded in the intracranial pressure –only group in blinded fashion. Tiered interventions in each arm were specified and impact on intracranial pressure and brain tissue oxygenation measured. Monitors were removed if values were normal for 48 hours consecutively, or after 5 days. Outcome was measured at 6 months using the Glasgow Outcome Scale–Extended.

Prevention of Exposure Keratopathy in Critically Ill Patients: A Single-Center, Randomized, Pilot Trial Comparing Ocular Lubrication With Bandage Contact Lenses and Punctal Plugs
Bendavid, I et al
Critical Care Medicine: November 2017 - Volume 45 - Issue 11 - p 1880–1886
To compare the effectiveness of bandage contact lenses and punctal plugs with ocular lubricants in preventing corneal damage in mechanically ventilated and sedated critically ill patients. Design: Single-center, prospective, randomized, pilot study. Setting: Sixteen-bed, general ICU at a tertiary academic medical center. Patients: Adults admitted to the ICU and anticipated to require mechanical ventilation and continuous sedation for greater than or equal to 4 days. Interventions: Patients were randomized to receive eye care with ocular lubricants (n = 38), bandage contact lenses (n = 33), or punctal plugs (n = 33). The bandage contact lenses were changed every 4 days, whereas the punctal plugs remained in situ for the entire study. Measurements and Main Results: The primary endpoint was the presence or absence of corneal damage as assessed by the grade of keratopathy. Patients were examined by an ophthalmologist blinded to the study group every 4 days and at the time of withdrawal from the study, due to cessation of sedation, discharge from the ICU, or death. The mean duration of the study was 8.6 ± 6.2 days. The grade of keratopathy in the ocular lubricant group increased significantly in both eyes (p = 0.01 for both eyes) while no worsening was noted in either the lens or punctal plugs groups. In a post hoc analysis of patients with an initially abnormal ophthalmic examination, significant healing of keratopathy was noted in the lens group (p = 0.02 and 0.018 for left and right eyes, respectively) and in the right eye of the plugs group (p = 0.005); no improvement was noted in the ocular lubricant group. Conclusions: Compared with ocular lubrication, bandage contact lenses and punctal plugs were more effective in limiting keratopathy, and their use, particularly of bandage contact lenses, was associate
with significant healing of existing lesions.

Investigating the Impact of Different Suspicion of Infection Criteria on the Accuracy of Quick Sepsis-Related Organ Failure Assessment, Systemic Inflammatory Response Syndrome, and Early Warning Scores
Investigating the Impact of Different Suspicion of Infection Criteria on the Accuracy of Quick Sepsis-Related Organ Failure Assessment, Systemic Inflammatory Response Syndrome, and Early Warning Scores
Churpek, M M et al
Critical Care Medicine: November 2017 - Volume 45 - Issue 11 - p 1805–1812
Abstract
Objective: Objective:Studies in sepsis are limited by heterogeneity regarding what constitutes suspicion of infection. We sought to compare potential suspicion criteria using antibiotic and culture order combinations in terms of patient characteristics and outcomes. We further sought to determine the impact of differing criteria on the accuracy of sepsis screening tools and early warning scores. Design: Design:Observational cohort study. Setting: Setting:Academic center from November 2008 to January 2016. Patients: Patients:Hospitalized patients outside the ICU. Interventions: Interventions:None. Measurements and Main Results: Measurements and Main Results:Six criteria were investigated: 1) any culture, 2) blood culture, 3) any culture plus IV antibiotics, 4) blood culture plus IV antibiotics, 5) any culture plus IV antibiotics for at least 4 of 7 days, and 6) blood culture plus IV antibiotics for at least 4 of 7 days. Accuracy of the quick Sepsis-related Organ Failure Assessment score, Sepsis-related Organ Failure Assessment score, systemic inflammatory response syndrome criteria, the National and Modified Early Warning Score, and the electronic Cardiac Arrest Risk Triage score were calculated for predicting ICU transfer or death within 48 hours of meeting suspicion criteria. A total of 53,849 patients met at least one infection criteria. Mortality increased from 3% for group 1 to 9% for group 6 and percentage meeting Angus sepsis criteria increased from 20% to 40%. Across all criteria, score discrimination was lowest for systemic inflammatory response syndrome (median area under the receiver operating characteristic curve, 0.60) and Sepsis-related Organ Failure Assessment score (median area under the receiver operating characteristic curve, 0.62), intermediate for quick Sepsis-related Organ Failure Assessment (median area under the receiver operating characteristic curve, 0.65) and Modified Early Warning Score (median area under the receiver operating characteristic curve 0.67), and highest for National Early Warning Score (median area under the receiver operating characteristic curve 0.71) and electronic Cardiac Arrest Risk Triage (median area under the receiver operating characteristic curve 0.73). Conclusions: Conclusions:The choice of criteria to define a potentially infected population significantly impacts prevalence of mortality but has little impact on accuracy. Systemic inflammatory response syndrome was the least predictive and electronic Cardiac Arrest Risk Triage the most predictive regardless of how infection was defined.

Quick Sequential Organ Failure Assessment and Systemic Inflammatory Response Syndrome Criteria as Predictors of Critical Care Intervention Among Patients With Suspected Infection
Quick Sequential Organ Failure Assessment and Systemic Inflammatory Response Syndrome Criteria as Predictors of Critical Care Intervention Among Patients With Suspected Infection
Moskowitz, A et al
Critical Care Medicine: November 2017 - Volume 45 - Issue 11 - p 1813–1819
Objectives: Objectives:The Sepsis III clinical criteria for the diagnosis of sepsis rely on scores derived to predict inhospital mortality. In this study, we introduce the novel outcome of “received critical care intervention” and investigate the related predictive performance of both the quick Sequential Organ Failure Assessment and the Systemic Inflammatory Response Syndrome criteria.
Design:This was a single-center, retrospective analysis of electronic health records. Setting: Setting:Tertiary care hospital in the United States. Patients: Patients:Patients with suspected infection who presented to the emergency department and were admitted to the hospital between January 2010 and December 2014. Interventions: Interventions:Systemic Inflammatory Response Syndrome and quick Sequential Organ Failure Assessment scores were calculated, and their relationships to the receipt of critical care intervention and inhospital mortality were determined.
Measurement and Main Results:A total of 24,164 patients were included of whom 6,693 (27.7%) were admitted to an ICU within 48 hours; 4,453 (66.5%) patients admitted to the ICU received a critical care intervention. Among those with quick Sequential Organ Failure Assessment less than 2, 13.4% received a critical care intervention and 3.5% died compared with 48.2% and 13.4%, respectively, for quick Sequential Organ Failure Assessment greater than or equal to 2. The area under the receiver operating characteristic was similar whether quick Sequential Organ Failure Assessment was used to predict receipt of critical care intervention or inhospital mortality (0.74 [95% CI, 0.73–0.74] vs 0.71 [0.69–0.72]). The area under the receiver operating characteristic of Systemic Inflammatory Response Syndrome for critical care intervention (0.69) and mortality (0.66) was lower than that for quick Sequential Organ Failure Assessment (p < 0.001 for both outcomes). The sensitivity of quick Sequential Organ Failure Assessment for predicting critical care intervention was 38%.
Conclusions: Emergency department patients with suspected infection and low quick Sequential Organ Failure Assessment scores frequently receive critical care interventions. The misclassification of these patients as “low risk,” in combination with the low sensitivity of quick Sequential Organ Failure Assessment greater than or equal to 2, may diminish the clinical utility of the quick Sequential Organ Failure Assessment score for patients with suspected infection in the emergency department.

Severe Respiratory Failure, Extracorporeal Membrane Oxygenation, and Intracranial Hemorrhage
Severe Respiratory Failure, Extracorporeal Membrane Oxygenation, and Intracranial Hemorrhage
Lockie, CJ et al
Critical Care Medicine: October 2017 - Volume 45 - Issue 10 - p 1642–1649
Objectives: For patients supported with veno-venous extracorporeal membrane oxygenation, the occurrence of intracranial hemorrhage is associated with a high mortality. It is unclear whether intracranial hemorrhage is a consequence of the extracorporeal intervention or of the underlying severe respiratory pathology. In a cohort of patients transferred to a regional severe respiratory failure center that routinely employs admission brain imaging, we sought 1) the prevalence of intracranial hemorrhage; 2) survival and neurologic outcomes; and 3) factors associated with intracranial hemorrhage.
Design: A single-center, retrospective, observational cohort study. Setting: Tertiary referral severe respiratory failure center, university teaching hospital. Patients: Patients admitted between December 2011 and February 2016. Intervention: None. Measurements and Main Results: Three hundred forty-two patients were identified: 250 managed with extracorporeal support and 92 managed using conventional ventilation. The prevalence of intracranial hemorrhage was 16.4% in extracorporeal membrane oxygenation patients and 7.6% in conventionally managed patients (p = 0.04). Multivariate analysis revealed factors independently associated with intracranial hemorrhage to be duration of ventilation (d) (odds ratio, 1.13 [95% CI, 1.03–1.23]; p = 0.011) and admission fibrinogen (g/L) (odds ratio, 0.73 [0.57–0.91]; p = 0.009); extracorporeal membrane oxygenation was not an independent risk factor (odds ratio, 3.29 [0.96–15.99]; p = 0.088). In patients who received veno-venous extracorporeal membrane oxygenation, there was no significant difference in 6-month survival between patients with and without intracranial hemorrhage (68.3% vs 76.0%; p = 0.350). Good neurologic function was observed in 92%. Conclusions: We report a higher prevalence of intracranial hemorrhage than has previously been described with high level of neurologically intact survival. Duration of mechanical ventilation and admission fibrinogen, but not exposure to extracorporeal support, are independently associated with intracranial hemorrhage.

Outcomes of Patient- and Family-Centered Care Interventions in the ICU: A Systematic Review and Meta-Analysis
Goldfarb, M J et al
Critical Care Medicine: October 2017 - Volume 45 - Issue 10 - p 1751–1761
Objective: To determine whether patient- and family-centered care interventions in the ICU improve outcomes. Data Sources: We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library databases from inception until December 1, 2016. Study Selection: We included articles involving patient- and family-centered care interventions and quantitative, patient- and family-important outcomes in adult ICUs. Data Extraction: We extracted the author, year of publication, study design, population, setting, primary domain investigated, intervention, and outcomes.
Data Synthesis: There were 46 studies (35 observational pre/post, 11 randomized) included in the analysis. Seventy-eight percent of studies (n = 36) reported one or more positive outcome measures, whereas 22% of studies (n = 10) reported no significant changes in outcome measures. Random-effects meta-analysis of the highest quality randomized studies showed no significant difference in mortality (n = 5 studies; odds ratio = 1.07; 95% CI, 0.95–1.21; p = 0.27; I2 = 0%), but there was a mean decrease in ICU length of stay by 1.21 days (n = 3 studies; 95% CI, –2.25 to –0.16; p = 0.02; I2 = 26%). Improvements in ICU costs, family satisfaction, patient experience, medical goal achievement, and patient and family mental health outcomes were also observed with intervention; however, reported outcomes were heterogeneous precluding formal meta-analysis.
Conclusions: Patient- and family-centered care–focused interventions resulted in decreased ICU length of stay but not mortality. A wide range of interventions were also associated with improvements in many patient- and family-important outcomes. Additional high-quality interventional studies are needed to further evaluate the effectiveness of patient- and family-centered care in the intensive care setting.

Reading between the lines, the key to successfully implementing early rehabilitation in critical care
Reading between the lines, the key to successfully implementing early rehabilitation in critical care
McWilliams DJ
Intensive and Critical Care Nursing , October 2017 Volume 42, Pages 5–7
The number of critically ill individuals, complexity of illness, and cost of critical care has continued to increase over time (Bauman and Hyzy, 2014). Although this represents an older critical care population than previously seen, presenting with a variety of pre-existing comorbidities, improvements in intensive care services and delivery have meant survival rates have improved in recent years (Esteban et al., 2013; Kaukonen et al., 2014). When considering successful outcomes from critical illness, it is now acknowledged that it is no longer sufficient or appropriate to consider survival alone (Desai et al., 2011).

Objectives: The objectives of this study were to 1) assess patterns of early crystalloid resuscitation provided to sepsis and septic shock patients at initial presentation and 2) determine the association between time to initial crystalloid resuscitation with hospital mortality, mechanical ventilation, ICU utilization, and length of stay.
Design: Consecutive-sample observational cohort. Setting: Nine tertiary and community hospitals over 1.5 years. Patients: Adult sepsis and septic shock patients captured in a prospective quality improvement database inclusion criteria: suspected or confirmed infection, greater than or equal to two systemic inflammatory response criteria, greater than or equal to one organ-dysfunction criteria. Interventions: The primary exposure was crystalloid initiation within 30 minutes or lesser, 31–120 minutes, or more than 120 minutes from sepsis identification. Measurements and Main Results: We identified 11,182 patients. Crystalloid initiation was faster for emergency department patients (β, –141 min; CI, –159 to –125; p < 0.001), baseline hypotension (β, –39 min; CI, –48 to –32; p < 0.001), fever, urinary or skin/soft-tissue source of infection. Initiation was slower with heart failure (β, 20 min; CI, 14–25; p < 0.001), and renal failure (β, 16 min; CI, 10–22; p < 0.001). Five thousand three hundred thirty-six patients (48%) had crystalloid initiated in 30 minutes or lesser versus 2,388 (21%) in 31–120 minutes, and 3,458 (31%) in more than 120 minutes. The patients receiving fluids within 30 minutes had lowest mortality (949 [17.8%]) versus 31–120 minutes (446 [18.7%]) and more than 120 minutes (846 [24.5%]). Compared with more than 120 minutes, the adjusted odds ratio for mortality was 0.76 (CI, 0.64–0.90; p = 0.002) for 30 minutes or lesser and 0.76 (CI, 0.62–0.92; p = 0.004) for 31–120 minutes. When assessed continuously, mortality odds increased by 1.09 with each hour to initiation (CI, 1.03–1.16; p = 0.002). We observed similar patterns for mechanical ventilation, ICU utilization, and length of stay. We did not observe significant interaction for mortality risk between initiation time and baseline heart failure, renal failure, hypotension, acute kidney injury, altered gas exchange, or emergency department (vs inpatient) presentation.
Conclusions: Crystalloid was initiated significantly later with comorbid heart failure and renal failure, with absence of fever or hypotension, and in inpatient-presenting sepsis. Earlier crystalloid initiation was associated with decreased mortality. Comorbidities and severity did not modify this effect.

Objectives: Hyponatremic encephalopathy, symptomatic cerebral edema due to a low osmolar state, is a medical emergency and often encountered in the ICU setting. This article provides a critical appraisal and review of the literature on identification of high-risk patients and the treatment of this life-threatening disorder. Data Sources, Study Selection, and Data Extraction: Online search of the PubMed database and manual review of articles involving risk factors for hyponatremic encephalopathy and treatment of hyponatremic encephalopathy in critical illness. Data Synthesis: Hyponatremic encephalopathy is a frequently encountered problem in the ICU. Prompt recognition of hyponatremic encephalopathy and early treatment with hypertonic saline are critical for successful outcomes. Manifestations are varied, depending on the extent of CNS’s adaptation to the hypoosmolar state. The absolute change in serum sodium alone is a poor predictor of clinical symptoms. However, certain patient specific risks factors are predictive of a poor outcome and are important to identify. Gender (premenopausal and postmenopausal females), age (prepubertal children), and the presence of hypoxia are the three main clinical risk factors and are more predictive of poor outcomes than the rate of development of hyponatremia or the absolute decrease in the serum sodium.
Conclusions: In patients with hyponatremic encephalopathy exhibiting neurologic manifestations, a bolus of 100 mL of 3% saline, given over 10 minutes, should be promptly administered. The goal of this initial bolus is to quickly treat cerebral edema. If signs persist, the bolus should be repeated in order to achieve clinical remission. However, the total change in serum sodium should not exceed 5 mEq/L in the initial 1–2 hours and 15–20 mEq/L in the first 48 hours of treatment. It has recently been demonstrated in a prospective fashion that 500 mL of 3% saline at an infusion rate of 100 mL per hour can be given safely. It is critical to recognize the early signs of cerebral edema (nausea, vomiting, and headache) and intervene with IV 3% sodium chloride as this is the time to intervene rather than waiting until more severe symptoms develop. Cerebral demyelination is a rare complication of overly rapid correction of hyponatremia. The principal risk factors for cerebral demyelination are correction of the serum sodium more than 25 mEq/L in the first 48 hours of therapy, correction past the point of 140 mEq/L, chronic liver disease, and hypoxic/anoxic episode.

In the Intensive Care Unit (ICU), central venous line associated bloodstream infections (CLABSIs) represent an important component of healthcare-associated infections and are linked to increased morbidity, mortality and overall hospital-associated cost (Warren et al., 2006; Stevens et al., 2014). CLABSIs are considered a preventable cause of healthcare-associated patient’s adverse events. Despite major scientific advances in pathogenesis, surveillance methods and treatment approach, the most appropriate interventions to prevent and control CLABSIs remain debatable.

Delirium is a common syndrome that has both short and long-term negative outcomes for critically ill patients. Many studies over several years have found a knowledge gap and lack of evidence-based practice from critical care personnel, but there has been little exploration of the reasons for this.

Intensive and Critical Care Nursing Article in Press
Traditionally, nursing has been a female-dominated profession. Men employed as registered nurses have been in the minority and little is known about the experiences of this demographic. The purpose of this descriptive, quantitative study was to understand the relationship between the variables of demographics and causes of role strain among male nurses in critical care settings. The Sherrod Role Strain Scale assesses role strain within the context of role conflict, role overload, role ambiguity and role incongruity.
