A roadmap for developing an emergency department based critical care consultation service: Building the early intervention team (EIT).

Emergency Department (ED) crowding and boarding impact safe and effective health care delivery. ED clinicians must balance caring for new arrivals who require stabilization and resuscitation as well as those who need longitudinal care and re-evaluation. These challenges are magnified in the setting of critically ill patients boarding for the intensive care unit. Boarding is a complex issue that has multiple solutions based on resources at individual institutions. Several different models have been described for delivery of critical care in the ED. Here, we describe the development of an ED based critical care consultation service, the early intervention team, at an urban academic ED.

Incidence of Heparin-Induced Thrombocytopenia in Patients With Newly Implanted Mechanical Circulatory Support Devices.

BACKGROUND: Heparin exposure and device-related thrombocytopenia complicate the diagnosis of heparin-induced thrombocytopenia (HIT) in patients receiving mechanical circulatory support (MCS). To improve anticoagulation management for patients with newly implanted MCS devices, incidence of confirmed HIT needs to be further characterized. OBJECTIVES: The purpose of this study is to describe the incidence of HIT and clinical utility of the 4Ts score in patients with newly implanted MCS devices. METHODS: This is a retrospective analysis of MCS patients receiving unfractionated heparin from 2014 to 2017. The primary end point was incidence of laboratory-confirmed HIT. Strong positive, likely positive, low probability, and negative HIT categories were established based on heparin-induced platelet antibody (HIPA) and serotonin release assay (SRA). Secondary end points include characterization of platelet trends, argatroban use, incidence of HIT among each of the MCS devices, and utility of 4Ts score. RESULTS: A total of 342 patient encounters met inclusion criteria, of which 68 HIPA tests and 25 SRAs were ordered. The incidence of HIT was 0.88% (3/342) and 4.4% (3/68) in patients with suspected HIT. Of the 68 HIPA tests, 3 (4.4%) were considered strong positive and 3 of the 25 SRAs were positive. Median 4Ts score was 4 [2.5-4] and optical density 0.19 [0.11-0.54]. The positive predictive value for the 4Ts score was 0.15 (CI = 0.03-0.46) and negative predictive value, 0.93 (CI = 0.82-0.98). CONCLUSION AND RELEVANCE: HIT occurs infrequently with newly implanted MCS devices. The 4Ts score appears to have a high negative predictive value for ruling out HIT.

Critical Care Delivery Solutions in the Emergency Department: Evolving Models in Caring for ICU Boarders.

The National Academy of Medicine has identified emergency department (ED) crowding as a health care delivery problem. Because the ED is a portal of entry to the hospital, 25% of all ED encounters are related to critical illness. Crowding at both an ED and hospital level can thus lead to boarding of a number of critically ill patients in the ED. EDs are required to not only deliver immediate resuscitative and stabilizing care to critically ill patients on presentation but also provide longitudinal care while boarding for the ICU. Crowding and boarding are multifactorial and complex issues, for which different models for delivery of critical care in the ED have been described. Herein, we provide a narrative review of different models of delivery of critical care reported in the literature and highlight aspects for consideration for successful local implementation.

The GENESIS project (GENeralized Early Sepsis Intervention Strategies): a multicenter quality improvement collaborative.

BACKGROUND: Improved outcomes for severe sepsis and septic shock have been consistently observed with implementation of early best practice intervention strategies or the 6-hour resuscitation bundle (RB) in single-center studies. This multicenter study examines the in-hospital mortality effect of GENeralized Early Sepsis Intervention Strategies (GENESIS) when utilized in community and tertiary care settings. METHODS: This study was comprised of 2 strategies to assess treatment. The first was a prospective before-and-after observational comparison of historical controls to patients receiving the RB after implementation of GENESIS in 4 community and 4 tertiary hospitals. The second was a concurrent examination comparing patients not achieving all components of the RB to those achieving all components of the RB in 1 community and 2 tertiary care hospitals after implementation of GENESIS. These 4 subgroups merged to comprise a control (historical controls treated before GENESIS and RB not achieved after GENESIS) group and treatment (patients treated after GENESIS and RB achieved after GENESIS) group for comparison. RESULTS: The control group comprised 1554 patients not receiving the RB (952 before GENESIS and 602 RB not achieved after GENESIS). The treatment group comprised 4801 patients receiving the RB (4109 after GENESIS and 692 RB achieved after GENESIS). Patients receiving the RB (treatment group) experienced an in-hospital mortality reduction of 14% (42.8%-28.8%, P < .001) and a 5.1 day decrease in hospital length of stay (20.7 vs 15.6, P < .001) compared to those not receiving the RB (control group). Similar mortality reductions were seen in the before-and-after (43% vs 29%, P < .001) or concurrent RB not achieved versus achieved (42.5% vs 27.2%, P < .001) subgroup comparisons. CONCLUSIONS: Patients with severe sepsis and septic shock receiving the RB in community and tertiary hospitals experience similar and significant reductions in mortality and hospital length of stay. These findings remained consistent when examined in both before-and-after and concurrent analyses. Early sepsis intervention strategies are associated with 1 life being saved for every 7 treated.

Accelerated Critical Therapy Now in the Emergency Department Using an Early Intervention Team: The Impact of Early Critical Care Consultation for ICU Boarders.

Evaluate the impact of an emergency department (ED)-based critical care consultation service, hypothesizing early consultation results in shorter hospital length of stay (LOS). DESIGN: Retrospective observational study from February 2018 to 2020. SETTING: An urban academic quaternary referral center. PATIENTS: Adult patients greater than or equal to 18 years admitted to the ICU from the ED. Exclusion criteria included age less than 18 years, do not resuscitate/do not intubate documented prior to arrival, advanced directives outlining limitations of care, and inability to calculate baseline modified Sequential Organ Failure Assessment (mSOFA) score. INTERVENTIONS: ED-based critical care consultation by an early intervention team (EIT) initiated by the primary emergency medicine physician compared with usual practice. MEASUREMENTS: The primary outcome was hospital LOS, and secondary outcomes were hospital mortality, ICU LOS, ventilator-free days, and change in the mSOFA. MAIN RESULTS: A total 1,764 patients met inclusion criteria, of which 492 (27.9%) were evaluated by EIT. Final analysis, excluding those without baseline mSOFA score, limited to 1,699 patients, 476 in EIT consultation group, and 1,223 in usual care group. Baseline mSOFA scores (±sd) were higher in the EIT consultation group at 3.6 (±2.4) versus 2.6 (±2.0) in the usual care group. After propensity score matching, there was no difference in the primary outcome: EIT consultation group had a median (interquartile range [IQR]) LOS of 7.0 days (4.0-13.0 d) compared with the usual care group median (IQR) LOS of 7.0 days (4.0-13.0 d), p = 0.64. The median (IQR) boarding time was twice as long subjects in the EIT consultation group at 8.0 (5.0-15.0) compared with 4.0 (3.0-7.0) usual care, p < 0.001. CONCLUSIONS: An ED-based critical care consultation model did not impact hospital LOS. This model was used in the ED and the EIT cared for critically ill patients with higher severity of illness and longer ED boarding times.

Lung Transplantation for the Treatment of Vaping-Induced, Irreversible, End-Stage Lung Injury.

Recently, there has been a rise in the incidence of E-cigarette/Vaping-Associated Lung Injury (EVALI) in the United States, mostly involving tetrahydrocannabinol. Current treatment strategies for EVALI are aimed at controlling the inflammatory and infectious causes, in addition to supportive care. Although most patients improve with supportive measures, the long-term pulmonary effects of this illness are still not well defined. This report describes a case of EVALI resulting in progressive, irreversible destruction of the lung parenchyma that was treated with double lung transplantation.

Sonographic Assessment of Intravascular Fluid Estimate (SAFE) Score by Using Bedside Ultrasound in the Intensive Care Unit.

OBJECTIVE: The objective of the study was to use an ultrasound-based numerical scoring system for assessment of intravascular fluid estimate (SAFE) and test its validity. METHODS: A prospective, observational study was carried out in the surgical intensive care unit (ICU) of an urban tertiary care teaching hospital. Patient's intravascular volume status was assessed using the standard methods of heart rate, blood pressure, central venous pressure, cardiac output, lactate and saturation of venous oxygen, and others. This was compared with assessment using bedside ultrasound evaluation of the cardiac function, inferior vena cava, lungs, and the internal jugular vein. Applying a numerical scoring system was evaluated by Fisher's exact testing and multinomial logistic model to predict the volume status based on ultrasound scores and the classification accuracy. RESULTS: 61 patients in the ICU were evaluated. 21 (34.4% of total) patients diagnosed with hypovolemia, and their ultrasound volume score was -4 in 14 (66.7%) patients, -3 in 5 (23.8%) patients, and 0 in 2 (9.5%) patients (p < 0.001). 18 (29.5% of total) patients diagnosed with euvolemia, and their ultrasound volume score was 0 in 11 (61.1%) patients, +1 in 4 (22.2%) patients, and -1 in 1 (5.6%) patient (p < 0.001). 18 (29.5% of total) patients diagnosed with euvolemia, and their ultrasound volume score was 0 in 11 (61.1%) patients, +1 in 4 (22.2%) patients, and -1 in 1 (5.6%) patient (p < 0.001). 18 (29.5% of total) patients diagnosed with euvolemia, and their ultrasound volume score was 0 in 11 (61.1%) patients, +1 in 4 (22.2%) patients, and -1 in 1 (5.6%) patient (p < 0.001). 18 (29.5% of total) patients diagnosed with euvolemia, and their ultrasound volume score was 0 in 11 (61.1%) patients, +1 in 4 (22.2%) patients, and -1 in 1 (5.6%) patient (. CONCLUSION: Using the SAFE scoring system to identify the IVV status in critically ill patients significantly correlates with the standard measures. A SAFE score of -4 to -2 more likely represents hypovolemia, -1 to +1 more likely represents euvolemia, and +2 to +4 more likely to be hypervolemia.

Argatroban dosing requirements in extracorporeal life support and other critically ill populations.

Argatroban is a parenteral direct thrombin inhibitor that requires close monitoring to ensure safety and efficacy. Limited data exist to describe its effect in critically ill patients. This was a retrospective, single-center, cohort study that aimed to compare argatroban dosing requirements in those receiving extracorporeal life support (ECLS), continuous renal replacement therapy (CRRT), or neither. Organ dysfunction was assessed using a modified version of the Sequential Organ Failure Assessment (modSOFA) that incorporated the use of extracorporeal support systems. Eighty patients were included in the study (n = 20, 20, 40 in the ECLS, CRRT, and support-free groups, respectively). The majority of patients were Child-Pugh classification B (73%). Median modSOFA scores were higher in the ECLS (16.5) and CRRT (15.5) groups than in the support-free group (7.5) (P < .001). There was no difference in the primary outcome of first therapeutic argatroban dose between the three groups (0.5 µg/kg/min for each; IQRs 0.25-0.50, 0.11-0.50, and 0.25-0.50, respectively; P = .455). The ECLS group had the lowest mean (0.39 µg/kg/min), minimum (0.20 µg/kg/min), and final (0.43 µg/kg/min) doses. ECLS patients had more supratherapeutic aPTTs and dose changes overall, supporting the need for more frequent anticoagulation monitoring or dose reductions in this population. Total modSOFA score demonstrated a moderate inverse correlation with first therapeutic dose (dose = 0.54 - (modSOFA score × 0.012); R = -0.342, P = .002). Overall, initial argatroban doses of 0.3-0.5 µg/kg/min appear to achieve therapeutic aPTT values in the studied populations.

Do the American College of Surgeons' "major resuscitation" trauma triage criteria predict emergency operative management?

STUDY OBJECTIVE: We wish to assess whether individual or collective American College of Surgeons' "major resuscitation" criteria accurately identify injured patients who receive emergency operative treatment. METHODS: In this observational secondary registry analysis of 8,289 consecutive trauma team activations during a 7.5-year period, we evaluated the test performance of 5 American College of Surgeons' major criteria in predicting emergency (within 1 hour) operative management by general (for adults) or pediatric (for children) surgeons. RESULTS: In adults, the individual major resuscitation criteria each predicted emergency operative management as follows (sorted from highest to lowest test performance): gunshot wounds to the neck or torso (likelihood ratio positive [LR+] 7.5; 95% confidence interval [CI] 6.2 to 9.1); confirmed hypotension (LR+ 5.3; 95% CI 4.0 to 7.1); interhospital transfers requiring blood transfusions (LR+ 4.6; 95% CI 2.6 to 8.2); respiratory compromise (LR+ 2.9; 95% CI 2.2 to 3.7), and Glasgow Coma Scale score less than 8 (LR+ 2.1; 95% CI 1.6 to 2.7). The collective strategy of using any of these 5 criteria exhibited a LR+ of 3.5 (95% CI 3.2 to 3.8), sensitivity 82% (95% CI 75% to 87%), and specificity 76% (95% CI 75% to 77%). Our findings in children were similar, but their precision was limited by the low baseline prevalence of emergency operative intervention. CONCLUSION: These 5 American College of Surgeons-mandated major resuscitation criteria vary several-fold in their individual ability to predict emergency operative management and collectively exhibit modest test characteristics for this purpose. Selective use of these criteria or revisions thereof could result in more efficient secondary trauma triage. Our results do not support the existing obligatory use of these criteria to maintain American College of Surgeons trauma center certification.

Clinical decision rules for secondary trauma triage: predictors of emergency operative management.

STUDY OBJECTIVE: Most injured patients taken by ambulance to hospital emergency departments do not require emergency surgery, yet most US trauma centers require a surgeon to be present on their arrival. If a clinical decision rule could be developed to accurately identify which injured patients require emergency operative intervention, then such "secondary triage" criteria could permit a trauma center to more efficiently use their surgeons' time. METHODS: We analyzed 7.5 years of data (8,289 consecutive trauma activations) in our prospectively maintained Level I trauma center registry. We used classification and regression tree analyses to generate clinical decision rules using standard out-of-hospital variables to identify emergency operative intervention (within 1 hour) by a general surgeon (for adults) or a pediatric surgeon (if < or =14 years). RESULTS: Emergency operative intervention occurred in 3.0% of adults and 0.35% of children. For adults, summoning a surgeon for any one of 3 criteria (penetrating mechanism, systolic blood pressure <96 mm Hg, pulse rate >104 beats/min) could reduce surgeon calls by 51.2% while failing to identify emergency operative intervention in only 0.08% (rule sensitivity 97.2% and specificity 48.6%). For children, no rule at all (ie, never automatically summoning a surgeon) would fail to identify emergency operative intervention in only 0.35% of patients, and use of a single criterion (penetrating mechanism) would reduce surgeon calls by 96.2% while failing to identify emergency operative intervention in only 0.09% (rule sensitivity 75.0% and specificity 96.5%). CONCLUSION: We have derived simple decision rules for trauma centers that, if validated, could substantially reduce the need for routine surgeon presence on trauma patient arrival. These rules demonstrate low false-negative rates.

Inferior vena cava collapsibility loses correlation with internal jugular vein collapsibility during increased thoracic or intra-abdominal pressure.

PURPOSE: Point-of-care ultrasound evaluates inferior vena cava (IVC) and internal jugular vein (IJV) measurements to estimate intravascular volume status. The reliability of the IVC and IJV collapsibility index during increased thoracic or intra-abdominal pressure remains unclear. METHODS: Three phases of sonographic scanning were performed: spontaneous breathing phase, increased thoracic pressure phase via positive pressure ventilation (PPV) phase, and increased intra-abdominal pressure (IAP) phase via laparoscopic insufflation to 15 mmHg. IVC measurements were done at 1-2 cm below the diaphragm and IJV measurements were done at the level of the cricoid cartilage during a complete respiratory cycle. Collapsibility index was calculated by (max diameter - min diameter)/max diameter × 100 %. Chi square, t test, correlation procedure (CORR) and Fisher's exact analyses were completed. RESULTS: A total of 144 scans of the IVC and IJV were completed in 16 patients who underwent laparoscopic surgery. Mean age was 46 ± 15 years, with 75 % female and 69 % African-American. IVC and IJV collapsibility correlated in the setting of spontaneous breathing (r (2) = 0.86, p < 0.01). IVC collapsibility had no correlation with the IJV in the setting of PPV (r (2) = 0.21, p = 0.52) or IAP (r (2) = 0.26, p = 0.42). Maximal IVC diameter was significantly smaller during increased IAP (16.5 mm ± 4.9) compared to spontaneous breathing (20.6 mm ± 4.8, p = 0.04) and PPV (21.8 mm ± 5.6, p = 0.01). CONCLUSION: IJV and IVC collapsibility correlated during spontaneous breathing but there was no statistically significant correlation during increased thoracic or intra-abdominal pressure. Increased intra-abdominal pressure was associated with a significant smaller maximal IVC diameter and cautions the reliability of IVC diameter in clinical settings that are associated with intra-abdominal hypertension or abdominal compartment syndrome.

Feasibility of common carotid artery point of care ultrasound in cardiac output measurements compared to invasive methods.

BACKGROUND: Cardiac output (CO) measurement in the intensive care unit (ICU) requires invasive devices such as the pulmonary artery (PA) catheter or arterial waveform pulse contour analysis (PCA). This study tests the accuracy and feasibility of point of care ultrasound (POCUS) of the common carotid artery to estimate the CO non-invasively and compare it to existing invasive CO measurement modalities. METHODS: Patients admitted to the surgical and cardiothoracic ICU in a tertiary university-affiliated academic center during a 4-month period, with invasive hemodynamic monitoring devices for management, were included in this cohort study. Common carotid artery POCUS was performed to measure the CO and the results were compared to an invasive device. RESULTS: Intensivists and ICU fellows, using ultrasound of the common carotid artery, obtained the CO measurements. Images of the Doppler flow and volume were obtained at the level of the thyroid gland. Concurrent CO measured via invasive devices was recorded. The patient cohort comprised 36 patients; 52 % were females. The average age was 59 ± 13 years, and 66 % were monitored via PCA device and 33 % via PA catheter. Intraclass correlation coefficient (ICC) analysis demonstrated almost perfect correlation (0.8152) between measurements of CO via ultrasound vs. invasive modalities. The ICC between POCUS and the invasive measurement via PCA was 0.84 and via PA catheter 0.74, showing substantial agreement between the ultrasound and both invasive modalities. CONCLUSIONS: Common carotid artery POCUS offers a non-invasive method of measuring the CO in the critically ill population.

Point of care ultrasound (POCUS) telemedicine project in rural Nicaragua and its impact on patient management.

BACKGROUND: Point of care ultrasound (POCUS) is a useful diagnostic tool in medicine. POCUS provides an easy and reproducible method of diagnosis where conventional radiologic studies are unavailable. Telemedicine is also a great means of communication between educators and students throughout the world. HYPOTHESIS: Implementing POCUS with didactics and hands-on training, using portable ultrasound devices followed by telecommunication training, will impact the differential diagnosis and patient management in a rural community outside the United States. MATERIALS AND METHODS: This is an observational prospective study implementing POCUS in Las Salinas, a small village in rural western Nicaragua. Ultrasound was used to confirm a diagnosis based on clinical exam, or uncover a new, previously unknown diagnosis. The primary endpoint was a change in patient management. International sonographic instructors conducted didactic and practical training of local practitioners in POCUS, subsequently followed by remote guidance and telecommunication for 3 months. RESULTS: A total of 132 patients underwent ultrasound examination. The most common presentation was for a prenatal exam (23.5 %), followed by abdominal pain (17 %). Of the 132 patients, 69 (52 %) were found to have a new diagnosis. Excluding pregnancy, 67 patients of 101 (66 %) were found to have a new diagnosis. A change in management occurred in a total of 64 (48 %) patients, and 62 (61 %) after excluding pregnancy. CONCLUSION: Implementing POCUS in rural Nicaragua led to a change in management in about half of the patients examined. With the appropriate training of clinicians, POCUS combined with telemedicine can positively impact patient care.

Model Point-of-Care Ultrasound Curriculum in an Intensive Care Unit Fellowship Program and Its Impact on Patient Management.

Objectives. This study was designed to assess the clinical applicability of a Point-of-Care (POC) ultrasound curriculum into an intensive care unit (ICU) fellowship program and its impact on patient care. Methods. A POC ultrasound curriculum for the surgical ICU (SICU) fellowship was designed and implemented in an urban, academic tertiary care center. It included 30 hours of didactics and hands-on training on models. Minimum requirement for each ICU fellow was to perform 25-50 exams on respective systems or organs for a total not less than 125 studies on ICU. The ICU fellows implemented the POC ultrasound curriculum into their daily practice in managing ICU patients, under supervision from ICU staff physicians, who were instructors in POC ultrasound. Impact on patient care including finding a new diagnosis or change in patient management was reviewed over a period of one academic year. Results. 873 POC ultrasound studies in 203 patients admitted to the surgical ICU were reviewed for analysis. All studies included were done through the POC ultrasound curriculum training. The most common exams performed were 379 lung/pleural exams, 239 focused echocardiography and hemodynamic exams, and 237 abdominal exams. New diagnosis was found in 65.52% of cases (95% CI 0.590, 0.720). Changes in patient management were found in 36.95% of cases (95% CI 0.303, 0.435). Conclusions. Implementation of POC ultrasound in the ICU with a structured fellowship curriculum was associated with an increase in new diagnosis in about 2/3 and change in management in over 1/3 of ICU patients studied.

The incidence and significance of bacteremia in out of hospital cardiac arrest.

BACKGROUND: The most common etiology of cardiac arrest is presumed of myocardial origin. Recent retrospective studies indicate that preexisting pneumonia, a form of sepsis, is frequent in patients who decompensate with abrupt cardiac arrest without preceding signs of septic shock, respiratory failure or severe metabolic disorders shortly after hospitalization. The contribution of pre-existing infection on pre and post cardiac arrest events remains unknown and has not been studied in a prospective fashion. We sought to examine the incidence of pre-existing infection in out-of hospital cardiac arrest (OHCA) and assess characteristics associated with bacteremia, the goal standard for presence of infection. METHODS AND RESULTS: We prospectively observed 250 OHCA adult patients who presented to the Emergency Department (ED) between 2007 and 2009 to an urban academic teaching institution. Bacteremia was defined as one positive blood culture with non-skin flora bacteria or two positive blood cultures with skin flora bacteria. 77 met pre-defined exclusion criteria. Of the 173 OHCA adults, 65 (38%) were found to be bacteremic with asystole and PEA as the most common presenting rhythms. Mortality in the ED was significantly higher in bacteremic OHCA (75.4%) compared to non-bacteremic OHCA (60.2%, p<0.05). After adjustment for potential confounders, predictive factors associated with bacteremic OHCA were lower initial arterial pH, higher lactate, WBC, BUN and creatinine. CONCLUSIONS: Over one-third of OHCA adults were bacteremic upon presentation. These patients have greater hemodynamic instability and significantly increased short-term mortality. Further studies are warranted to address the epidemiology of infection as possible cause of cardiac arrest.

Racial differences in vasopressor requirements for septic shock.

OBJECTIVE: The objective of this study was to compare vasopressor requirements between African American (AA) patients and white patients in septic shock. METHODS: This was a retrospective cohort review conducted over a 2-year period measuring total and mean dosage of various vasopressors used between two racial groups during the treatment of patients admitted with septic shock. The study included patients admitted to the intensive care unit with septic shock at an 805-bed tertiary, academic center. All septic shock patients were managed with vasopressors. Vasopressor selection, dosage, and duration were at the discretion of the treating physician. Total, mean, and duration of vasopressor dosing requirements were obtained for study participants. Comorbidities, prehospitalization antihypertensive medication requirements, intravenous fluids given during the septic shock phase, and source of infection were analyzed. RESULTS: One hundred fifty-nine patients with septic shock were analyzed, of which 96 (60.4%) were AAs (P < 0.059). African Americans had higher rates of end-stage renal disease and hypertension compared with whites, 85.7% vs. 14.3% (P < 0.011; odds ratio [OR], 15.684) and 68.3% vs. 31.7% (P < 0.007; OR, 3.357), respectively. Norepinephrine (NE) was administered to 150 patients, 57.2% of which were AAs (P < 0.509). Thirteen patients received dopamine (5% AAs, P < 0.588), 40 patients received phenylephrine (15.7% AAs, P < 0.451), and five patients received epinephrine (1.9% AAs, P < 0.660). Comparing vasopressors between races, only NE showed statistical significance via logistic regression modeling for the AA race in terms of total dosage (AAs 736.8 [SD, 897.3] µg vs. whites 370 [SD, 554.2] µg, P < 0.003), duration of vasopressor used (AAs 38.38 [SD, 34.75] h vs. whites 29.09 [SD, 27.11] h, P < 0.037), and mean dosage (AAs 21.08 [SD, 22.23] µg/h vs. whites 12.37 [SD, 13.86] µg/h, P < 0.01). Mortality between groups was not significant. Logistic regression identified discrepancy of the mean dose NE in AAs compared with whites, with OR of 1.043 (P = 0.01). CONCLUSIONS: African American patients with septic shock were treated with higher doses of NE and required longer duration of NE administration compared with white patients.

Resuscitation bundle compliance in severe sepsis and septic shock: improves survival, is better late than never.

UNLABELLED: While clinicians' management of severe sepsis and septic shock has been positively influenced by a number of clinical research studies in the last decade, challenges remain regarding early hemodynamic optimization as envisioned in the Surviving Sepsis Campaign's (SSC) resuscitation bundle (RB). We examined the impact of a hospital-wide continuous quality improvement (CQI) initiative on patients presenting with severe sepsis and septic shock, and the impact of the sepsis RB on patient outcomes when completed beyond the 6-hour recommendation period. The study was an 18-month, prospective cohort study enrolling patients who met the definition of severe sepsis or septic shock. Compliance with the hemodynamic components of the sepsis RB was defined as achieving goal mean arterial pressure (MAP) ≥ 65 mm Hg, central venous pressure (CVP) ≥ 8 mm Hg, and central venous oxygen saturation (ScvO2) ≥ 70%. Compliance was assessed at 6 hours and 18 hours after diagnosis of severe sepsis or septic shock. In all, 498 patients with severe sepsis and/or septic shock were evaluated to determine the upper limit of the range of hours that compliance with the RB would still improve outcomes. Using 18 hours as a marker, Compliers at 18 hrs and Non-Compliers at 18 hrs were compared. There were 202 patients who had the RB completed in less than or equal to 18 hours. There were 296 patients who did not complete the RB at 18 hours. The Compliers at 18 hrs had a significant 10.2% lower hospital mortality 37.1% (22% relative reduction) compared to the Non-Compliers at 18 hrs hospital mortality of 47.3% (P < .03). When the two groups were adjusted for differences in baseline illness severity, the Compliers at 18 hrs had a greater reduction in predicted mortality of 26.8% versus 9.4%, P < 0.01. CONCLUSIONS: Initiating the sepsis RB for patients with severe sepsis and/or septic shock decreased mortality. A CQI initiative that monitored the implementation in real-time allowed for improvement in compliance and efficacy of the bundle on outcomes. Multiple studies have shown that compliance to the RB within 6 hours lowers hospital mortality. This study uniquely shows that when bundle completion is extended to 18 hours, the mortality reduction remains significant.

Standardized order sets for the treatment of severe sepsis and septic shock.

Evaluation of: Thiel SW, Asghar MF, Micek ST, Reichley RM, Doherty JA, Kollef MH. Hospital-wide impact of standardized order set for the management of bacteremic severe sepsis. Crit. Care Med. 37(3), 819-824 (2009). Aggressive standardized diagnostic and therapeutic approaches to acute diseases such as acute myocardial infarction, trauma and stroke have led to improved patient survival. A standardized order set for severe sepsis and septic shock represents a similar approach. In 2001, Rivers et al., using a standardized operating procedure to treat severe sepsis and septic shock, showed a relative risk reduction of 0.34 and absolute risk reduction of 16%, with a decrease in healthcare resource consumption for patients presenting to the emergency department. Since then, similar studies have shown similar or better results. This study in particular highlights a hospital-wide initiative that further confirms that standardized order sets and operating procedures for severe sepsis and septic shock result in a significant reduction in morbidity, mortality and healthcare resource consumption. With these robust findings, future emphasis should be placed on overcoming logistical, institutional and professional barriers to the implementation of standardized order sets, which can save the life of one out of every five to six patients presenting with severe sepsis and septic shock.
