The Effect of Early Severe Hyperoxia in Adults Intubated in the Prehosptial Setting or Emergency Department: A Scoping Review.

BACKGROUND: The detrimental effects of hyperoxia exposure have been well-described in patients admitted to intensive care units. However, data evaluating the effects of short-term, early hyperoxia exposure in patients intubated in the prehospital setting or emergency department (ED) have not been systematically reviewed. OBJECTIVE: Our aim was to quantify and describe the existing literature examining the clinical outcomes in ED patients exposed to hyperoxia within the first 24 h of mechanical ventilation. METHODS: This review was performed in concordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for scoping reviews. Two rounds of review using Rayyan QCRI software were performed for title and abstract screening and full-text search. Of the 2739 articles, 27 articles were retrieved after initial screening, of which 5 articles were excluded during the full-text screening, leaving 22 articles for final review and data extraction. RESULTS: Of 22 selected publications, 9 described patients with traumatic brain injury, 6 with cardiac arrest, 3 with multisystem trauma, 1 with stroke, 2 with septic shock, and 1 was heterogeneous. Three studies were randomized controlled trials. The available data have widely heterogeneous definitions of hyperoxia exposure, outcomes, and included populations, limiting conclusions. CONCLUSIONS: There is a paucity of data that examined the effects of severe hyperoxia exposure in the acute, post-intubation phase of the prehospital and ED settings. Further research with standardized definitions is needed to provide more detailed guidance regarding early oxygen titration in intubated patients.

Impact of COVID-19 Pandemic on Food Insecurity in an Urban Emergency Department Patient Population.

INTRODUCTION: Food insecurity (FI) has been associated with adverse health outcomes and increased healthcare expenditures. Many families experienced reduced access to food during the coronavirus disease 2019 (COVID-19) pandemic. A 2019 study revealed that the pre-pandemic prevalence of FI at an urban, tertiary care hospital's emergency department (ED) was 35.3%. We sought to evaluate whether the prevalence of FI in the same ED patient population increased during the COVID-19 pandemic. METHODS: We performed a single-center, observational, survey-based study. Surveys assessing for FI were administered to clinically stable patients presenting to the ED over 25 consecutive weekdays from November-December 2020. RESULTS: Of 777 eligible patients, 379 (48.8%) were enrolled; 158 (41.7%) screened positive for FI. During the pandemic, there was a 18.1% relative increase (or 6.4% absolute increase) in the prevalence of FI in this population (P=0.040; OR=1.309, 95% CI 1.012-1.693). The majority (52.9%) of food-insecure subjects reported reduced access to food due to the pandemic. The most common perceived barriers to access to food were reduced food availability at grocery stores (31%), social distancing guidelines (26.5%), and reduced income (19.6%). CONCLUSION: Our findings suggest that nearly half of the clinically stable patients who presented to our urban ED during the pandemic experienced food insecurity. The prevalence of FI in our hospital's ED patient population increased by 6.4% during the pandemic. Emergency physicians should be aware of rising FI in their patient population so that they may better support patients who must choose between purchasing food and purchasing prescribed medications.

External Validation of the COVID-NoLab and COVID-SimpleLab Prognostic Tools.

Our objective was to externally validate 2 simple risk scores for mortality among a mostly inpatient population with COVID-19 in Canada (588 patients for COVID-NoLab and 479 patients for COVID-SimpleLab). The mortality rates in the low-, moderate-, and high-risk groups for COVID-NoLab were 1.1%, 9.6%, and 21.2%, respectively. The mortality rates for COVID-SimpleLab were 0.0%, 9.8%, and 20.0%, respectively. These values were similar to those in the original derivation cohort. The 2 simple risk scores, now successfully externally validated, offer clinicians a reliable way to quickly identify low-risk inpatients who could potentially be managed as outpatients in the event of a bed shortage. Both are available online (https://ebell-projects.shinyapps.io/covid_nolab/ and https://ebell-projects.shinyapps.io/COVID-SimpleLab/).

The Survival of the Surviving Sepsis Campaign.

Even well-intentioned policies have great potential to cause harm. This statement is vividly illustrated by the influential, yet controversial, Surviving Sepsis Campaign guidelines and subsequent CMS benchmarks. Despite low-quality evidence, tendentious industry ties, and rebuke from the Infectious Disease Society of America (IDSA), these benchmarks continue to eschew therapy driven by clinician expertise and individual patient needs in favor of mandating an arbitrary, one-size-fits-all approach that suspends clinical judgment and promotes indiscriminate use of treatments that have the potential to cause great harm.

Advanced Triage Protocol: The Role of an Automated Lactate Order in Expediting Rapid Identification of Patients at Risk of Sepsis in the Emergency Department.

We undertook a process improvement initiative to expedite rapid identification of potential sepsis patients based on triage chief complaint, vital signs, and initial lactate level. DESIGN: Prospective cohort study. SETTING: Seven hundred-bed tertiary care hospital with ≅65,000 patient visits/yr. PATIENTS: Patients presenting to emergency department (ED) triage who met the following criteria: greater than or equal to two of the three systemic inflammatory response syndrome criteria assessable in triage, a chief complaint suggestive of infection, emergency severity index 2 or 3, and ambulatory to ED. INTERVENTIONS: A computer-generated lactate order was created, staff education and resources increased, and point-of-care lactate testing was introduced. MEASUREMENTS AND MAIN RESULTS: Primary endpoints include the following: percent of patients having a lactate level drawn, percent of lactate samples resulting before room placement, and time intervals from triage to lactate blood draw and to lactate result. Secondary endpoints were percentage of patients admitted to the hospital, percentage admitted to the ICU, and in-hospital mortality. Six thousand nine hundred six patients were included: 226 historic controls (HCs) and 6,680 intervention group patients. The mean serum lactate level was 1.77 ± 1.18 mmol/L. The percentage of patients having a lactate resulted increased from 27.4% in the HC period to 79.6%. The percentage of these lactate results available while the patient was still in the waiting room increased from 0.4% during the HC period to 33.7% during Phase 5 (p < 0.0001). In the intervention period, time from triage to lactate result decreased (78.1-63.4 min; p < 0.0001) and time to treatment room decreased (59.3-39.6 min; p < 0.0001). CONCLUSIONS: Implementation of a computerized lactate order using readily available data obtained during ED triage, combined with point-of-care lactate testing, improves time to lactate blood draw and lactate result in patients at risk for severe sepsis. Initial lactate levels correlated with admission to the hospital, admission to the ICU, and in-hospital mortality.

Development and Validation of a Two-Step Predictive Risk Stratification Model for Coronavirus Disease 2019 In-hospital Mortality: A Multicenter Retrospective Cohort Study.

Objectives: An accurate prognostic score to predict mortality for adults with COVID-19 infection is needed to understand who would benefit most from hospitalizations and more intensive support and care. We aimed to develop and validate a two-step score system for patient triage, and to identify patients at a relatively low level of mortality risk using easy-to-collect individual information. Design: Multicenter retrospective observational cohort study. Setting: Four health centers from Virginia Commonwealth University, Georgetown University, the University of Florida, and the University of California, Los Angeles. Patients: Coronavirus Disease 2019-confirmed and hospitalized adult patients. Measurements and Main Results: We included 1,673 participants from Virginia Commonwealth University (VCU) as the derivation cohort. Risk factors for in-hospital death were identified using a multivariable logistic model with variable selection procedures after repeated missing data imputation. A two-step risk score was developed to identify patients at lower, moderate, and higher mortality risk. The first step selected increasing age, more than one pre-existing comorbidities, heart rate >100 beats/min, respiratory rate ≥30 breaths/min, and SpO2 <93% into the predictive model. Besides age and SpO2, the second step used blood urea nitrogen, absolute neutrophil count, C-reactive protein, platelet count, and neutrophil-to-lymphocyte ratio as predictors. C-statistics reflected very good discrimination with internal validation at VCU (0.83, 95% CI 0.79-0.88) and external validation at the other three health systems (range, 0.79-0.85). A one-step model was also derived for comparison. Overall, the two-step risk score had better performance than the one-step score. Conclusions: The two-step scoring system used widely available, point-of-care data for triage of COVID-19 patients and is a potentially time- and cost-saving tool in practice.

Development and Validation of the COVID-NoLab and COVID-SimpleLab Risk Scores for Prognosis in 6 US Health Systems.

PURPOSE: Develop and validate simple risk scores based on initial clinical data and no or minimal laboratory testing to predict mortality in hospitalized adults with COVID-19. METHODS: We gathered clinical and initial laboratory variables on consecutive inpatients with COVID-19 who had either died or been discharged alive at 6 US health centers. Logistic regression was used to develop a predictive model using no laboratory values (COVID-NoLab) and one adding tests available in many outpatient settings (COVID-SimpleLab). The models were converted to point scores and their accuracy evaluated in an internal validation group. RESULTS: We identified 1340 adult inpatients with complete data for nonlaboratory parameters and 741 with complete data for white blood cell (WBC) count, differential, c-reactive protein (CRP), and serum creatinine. The COVID-NoLab risk score includes age, respiratory rate, and oxygen saturation and identified risk groups with 0.8%, 11.4%, and 40.4% mortality in the validation group (AUROCC = 0.803). The COVID-SimpleLab score includes age, respiratory rate, oxygen saturation, WBC, CRP, serum creatinine, and comorbid asthma and identified risk groups with 1.0%, 9.1%, and 29.3% mortality in the validation group (AUROCC = 0.833). CONCLUSIONS: Because they use simple, readily available predictors, developed risk scores have potential applicability in the outpatient setting but require prospective validation before use.

The Impact of a Comprehensive Simulation-Based Training and Certification Program on Resident Central Venous Catheter Complication Rates.

INTRODUCTION: Millions of central venous catheters (CVCs) are placed annually in the United States, many by resident physicians. Simulation training has been proposed as a means to increase resident physician competence with CVC placement and decrease the incidence of line-associated mechanical complications. We aimed to evaluate the impact of a novel simulation-based CVC training program for resident physicians on CVC-associated mechanical complication rates. We hypothesized that the CVC-related mechanical complication rates would be lower among simulation-trained residents (STRs) compared with nonsimulation, traditionally trained residents (TTRs). METHODS: A retrospective chart review was performed of patients with a CVC placed by a resident physician between October 2014 and January 2017 at MedStar Georgetown University Hospital in Washington, DC. Incidence of CVC mechanical complications, including pneumothorax, hemothorax, arterial injury, or retained guidewire, were extracted from the electronic medical record and compared between STR and TTR cohorts. In contrast to TTRs who were trained to place CVCs in a supervised clinical setting, STRs underwent a CVC training program using online modules, a hands-on simulation training and testing checklist, and a series of successful supervised insertions before being credentialed to place lines independently. RESULTS: Nine hundred twenty-four CVCs placed by resident physicians during the study period were analyzed. There was no statistically significant difference in total mechanical complication rates between the STRs and TTRs in this study period (2.4% vs. 2.2%, P = 1). Simulation-trained residents were more likely to use ultrasound guidance when indicated during CVC insertion compared with TTRs (94.8% vs. 70.5%, P < 0.001). CONCLUSIONS: Mechanical complication rates associated with CVC insertion were similar between the simulation and TTRs and were consistent with previously published literature. These findings suggest that residents who underwent simulation training and certification demonstrated performance on par with more experienced TTRs. In addition, they were more likely to use best practices including ultrasound guidance in line placement.

Multi-center implementation of automated age-adjusted D-dimer results reduces unnecessary PE imaging.

BACKGROUND: Several previous studies have investigated the clinical utility of age-adjusted D-dimer cutoffs for diagnosing pulmonary embolism (PE). OBJECTIVES: We performed a pre/post implementation study, using data from a mid-Atlantic healthcare system comprising 6 hospitals and 400,000 ED visits to determine whether implementing age adjusted D-dimer cutoffs reduced the number of imaging tests performed. METHODS: Retrospective study of all patients who had a D-dimer performed during ED visits between September 2015 to September 2018. On March 21, 2017, the D-dimer upper limit of normal system-wide was increased for patients over 50 to: Age (years) x 0.01µg/mL. D-dimer results were displayed as normal or high based on automated age adjustment. EHR Chart review was performed 1.5 years prior to implementation of age-adjusted D-dimer cutoffs, as well as 1.5 years after to evaluate mortality and test accuracy characteristics such as false negative rates. Comparisons were made using chi-square testing. RESULTS: 22,302 D-dimers were performed pre-implementation of which 10,837 (48.6%) were positive resulting in 7218 (32.3%) imaging studies. After implementation of age-adjusted d-dimer, 25,082 were performed of which 10,851 (43.2%) were positive resulting in 7017 (28.0%) imaging studies. (pre: 48.6%, post: 43.2%; p < 0.01). A significantly lower proportion of patients had a positive d-dimer (pre: 48.6%, post: 43.2%; p < 0.01) and underwent imaging post-implementation (pre: 32.3%, post: 28.0%; p < 0.05) a relative risk reduction of 13.3. This absolute risk reduction of 4.4% is associated with 1104 less scans in the post-implementation group while still increasing test accuracy from 53.7% to 59.2% (p < 0.05). CONCLUSION: Implementation of an automated age-adjusted D-dimer positive reference value reduced CT and V/Q imaging in this population by 4.4% while increasing test accuracy in a regional, heterogeneous six-hospital system.

Accuracy of Hemolyzed Potassium Levels in the Emergency Department.

INTRODUCTION: In the emergency department (ED), pseudohyperkalemia from hemolysis may indirectly harm patients by exposing them to increased length of stay, cost, and repeat blood draws. The need to repeat hemolyzed potassium specimens in low-risk patients has not been well studied. Our objective was to determine the rate of true hyperkalemia among low-risk, adult ED patients with hemolyzed potassium specimens. METHODS: We conducted this prospective observational study at two large (129,000 annual visits) academic EDs in the mid-Atlantic. Data were collected from June 2017-November 2017 as baseline data for planned departmental quality improvement and again from June 2018-November 2018. Inclusion criteria were an initial basic metabolic panel in the ED with a hemolyzed potassium level > 5.1 milliequivalents per liter that was repeated within 12 hours, age (≥18, and bicarbonate (HCO3) > 20. Exclusion criteria were age > 65, glomerular filtration rate (GFR) < 60, creatine phosphokinase > 500, hematologic malignancy, taking potassium-sparing or angiotensin-acting agents, or treatment with potassium-lowering agents (albuterol, insulin, HCO3, sodium polystyrene sulfonate, or potassium-excreting diuretic) prior to the repeat lab draw. RESULTS: Of 399 encounters with a hemolyzed, elevated potassium level in patients with GFR ≥ 60 and age > 18 that were repeated, we excluded 333 patients for age > 64, lab repeat > 12 hours, invalid identifiers, potassium-elevating or lowering medicines or hematologic malignancies.This left 66 encounters for review. There were no instances of hyperkalemia on the repeated, non-hemolyzed potassium levels, correlating to a true positive rate of 0% (95% confidence interval 0-6%). Median patient age was 46 (interquartile range [IQR] 34 - 56) years. Median hemolyzed potassium level was 5.8 (IQR 5.6 - 6.15) millimoles per liter (mmol/L), and median repeated potassium level was 3.9 (IQR 3.6 - 4.3) mmol/L. Median time between lab draws was 145 (IQR 87 - 262) minutes. CONCLUSION: Of 66 patients who met our criteria, all had repeat non-hemolyzed potassiums within normal limits. The median of 145 minutes between lab draws suggests an opportunity to decrease the length of stay for these patients. Our results suggest that in adult patients < 65 with normal renal function, no hematologic malignancy, and not on a potassium-elevating medication, there is little to no risk of true hyperkalemia. Further studies should be done with a larger patient population and multicenter trials.

The sensitivity of qSOFA calculated at triage and during emergency department treatment to rapidly identify sepsis patients.

The quick sequential organ failure assessment (qSOFA) score has been proposed as a means to rapidly identify adult patients with suspected infection, in pre-hospital, Emergency Department (ED), or general hospital ward locations, who are in a high-risk category with increased likelihood of "poor outcomes:" a greater than 10% chance of dying or an increased likelihood of spending 3 or more days in the ICU. This score is intended to replace the use of systemic inflammatory response syndrome (SIRS) criteria as a screening tool; however, its role in ED screening and identification has yet to be fully elucidated. In this retrospective observational study, we explored the performance of triage qSOFA (tqSOFA), maximum qSOFA, and first initial serum lactate (> 3 mmol/L) at predicting in-hospital mortality and compared these results to those for the initial SIRS criteria obtained in triage. A total of 2859 sepsis cases were included and the in-hospital mortality rate was 14.4%. The sensitivity of tqSOFA ≥ 2 and maximum qSOFA ≥ 2 to predict in-hospital mortality were 33% and 69%, respectively. For comparison, the triage SIRS criteria and the initial lactate > 3 mmol/L had sensitivities of 82% and 65%, respectively. These results demonstrate that in a large ED sepsis database the earliest measurement of end organ impairment, tqSOFA, performed poorly at identifying patients at increased risk of mortality and maximum qSOFA did not significantly outperform initial serum lactate levels.

Food Insecurity and Insulin Use in Hyperglycemic Patients Presenting to the Emergency Department.

INTRODUCTION: The prevalence of food insecurity (FI) and insulin rationing among patients with diabetes who present to the emergency department (ED) is unclear. We examined the prevalence of food insecurity and subtherapeutic insulin use among patients who presented to the ED with a blood glucose level of greater than 250 milligrams per deciliter. METHODS: This was a single-center, cross-sectional survey of clinically stable, hyperglycemic adults in the ED for food insecurity using the Hunger Vital Sign screening tool. Patients who were insulin dependent were asked about insulin usage and rationing. RESULTS: Of the 85 eligible patients, 76 (89.4%) were enrolled; 35 (46%) screened positive for food insecurity. Food insecure patients were 1.9 times more likely to be hospitalized than non-food insecure patients (relative risk = 1.90 [1.21-2.99], p<.01). Food insecure patients were younger than non-food insecure patients (50.4 vs 57.5 p<.02), and had significantly higher hemoglobin A1c (HgbA1c) levels (11.2% vs 9.9% p = 0.04). Of the 49 patients prescribed insulin, 17 (34.6%) stated they had used less insulin during the prior week than had been prescribed, and 21 (42.9%) stated they had used less insulin during the prior year than had been prescribed. Food insecure patients were more likely to have used less insulin than prescribed in the prior year (odds ratio = 3.60 [1.09-11.9], p = 0.04). CONCLUSION: Our exploratory findings suggest almost half of clinically stable adults presenting to our inner-city ED with hyperglycemia experience food insecurity. More than one-third of those prescribed insulin used less than their prescribed amount in the prior year.

Anatomic Site-Specific Complication Rates for Central Venous Catheter Insertions.

BACKGROUND: Central venous catheter (CVC) complication rates reflecting the application of modern insertion techniques to a clinically heterogeneous patient populations are needed to better understand procedural risk attributable to the 3 common anatomic insertion sites: internal jugular, subclavian, and femoral veins. We sought to define site-specific mechanical and duration-associated CVC complication rates across all hospital inpatients. METHODS: A retrospective chart review was conducted over 9 months at Georgetown University Hospital and Washington Hospital Center. Peripherally inserted central catheters and tunneled or fluoroscopically placed CVC's were excluded. Mechanical complications (retained guidewire, arterial injury, and pneumothorax) and duration-associated complications (deep vein thrombosis or pulmonary embolism, and central line-associated bloodstream infections) were identified. RESULTS: In all, 1179 CVC insertions in 801 adult patients were analyzed. Approximately 32% of patients had multiple lines placed. Of 1179 CVCs, 73 total complications were recorded, giving a total rate of one or more complications occurring per CVC of 5.9%. There was no statistically significant difference between site-specific complications. A total of 19 mechanical complications were documented, with a 1.5% complication rate of one or more mechanical complications occurring. A total of 54 delayed complications were documented, with a 4.4% complication rate of 1 or more delayed complications occurring. There were no statistically significant differences between anatomic sites for either total mechanical or total delayed complications. CONCLUSIONS: These results suggest that site-specific CVC complication rates may be less common than previously reported. These data further inform on the safety of modern CVC insertion techniques across all patient populations and clinical settings.

Frequency of Advanced Cardiac Life Support Medication Use and Association With Survival During In-hospital Cardiac Arrest.

PURPOSE: Cardiopulmonary resuscitation is common in the United States, with >200,000 people experiencing an in-hospital cardiac arrest (IHCA) annually. Recent medication shortages have raised the question of the frequency and type of medication used during cardiac arrest resuscitation. We sought to determine the frequency and quantity of medications used during IHCA. METHODS: This retrospective, single-center, medical record review was performed at a large, urban teaching hospital. Adults ≥18 years old who had an IHCA with confirmed loss of pulse between January 2017 and March 2018 were identified. A standardized data collection tool was used to extract data from the electronic medical record. The primary outcome was the frequency and quantity of medications used during the IHCA. Secondary outcomes included median time to defibrillation and frequency of sodium bicarbonate use, including among patients with end-stage renal disease (ESRD). FINDINGS: Criteria were met for 181 IHCA events. Demographic characteristics were 71% black, 17% white, mean age of 65 years, and 46% women. Epinephrine was given in 86.7% of the arrests, with a mean cumulative dose of 4.2 mg. Sodium bicarbonate was given in 63.5% of the arrests, with a mean cumulative dose of 9.0 g (1.9 amps). Amiodarone was given in 30.9% of the arrests, with a mean cumulative dose of 311.8 mg. Median time to defibrillation was 2 min (interquartile range, 1-4 min). Preexisting ESRD was present in 24.8% of patients, of whom 71.1% received sodium bicarbonate. Sodium bicarbonate administration was associated with a lower likelihood of survival to discharge (odds ratio [OR] = 0.27; 95% CI, 0.11-0.66) as well as a lower rate of return to spontaneous circulation (ROSC) (OR = 0.35; 95% CI, 0.13-0.95). Magnesium administration was associated with a lower rate of ROSC (OR = 0.39; 95% CI, 0.15-0.98). Of note, in patients with preexisting ESRD, no medications were significantly associated with a change in likelihood of survival to discharge or rate of ROSC. In patients without preexisting ESRD, magnesium was associated with a lower rate of ROSC (OR = 0.23; 95% CI, 0.08-0.77). IMPLICATIONS: We found that in a hospital with established rapid response and code blue teams, numerous medications that are not recommended for routine use in cardiac arrest are still administered at significant frequencies. Furthermore, substantial amounts of drugs with known recent shortage are used in IHCA. Inc.

The ED-SED Study: A Multicenter, Prospective Cohort Study of Practice Patterns and Clinical Outcomes Associated With Emergency Department SEDation for Mechanically Ventilated Patients.

OBJECTIVES: To characterize emergency department sedation practices in mechanically ventilated patients, and test the hypothesis that deep sedation in the emergency department is associated with worse outcomes. DESIGN: Multicenter, prospective cohort study. SETTING: The emergency department and ICUs of 15 medical centers. PATIENTS: Mechanically ventilated adult emergency department patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All data involving sedation (medications, monitoring) were recorded. Deep sedation was defined as Richmond Agitation-Sedation Scale of -3 to -5 or Sedation-Agitation Scale of 2 or 1. A total of 324 patients were studied. Emergency department deep sedation was observed in 171 patients (52.8%), and was associated with a higher frequency of deep sedation in the ICU on day 1 (53.8% vs 20.3%; p < 0.001) and day 2 (33.3% vs 16.9%; p = 0.001), when compared to light sedation. Mean (SD) ventilator-free days were 18.1 (10.8) in the emergency department deep sedation group compared to 20.0 (9.8) in the light sedation group (mean difference, 1.9; 95% CI, -0.40 to 4.13). Similar results according to emergency department sedation depth existed for ICU-free days (mean difference, 1.6; 95% CI, -0.54 to 3.83) and hospital-free days (mean difference, 2.3; 95% CI, 0.26-4.32). Mortality was 21.1% in the deep sedation group and 17.0% in the light sedation group (between-group difference, 4.1%; odds ratio, 1.30; 0.74-2.28). The occurrence rate of acute brain dysfunction (delirium and coma) was 68.4% in the deep sedation group and 55.6% in the light sedation group (between-group difference, 12.8%; odds ratio, 1.73; 1.10-2.73). CONCLUSIONS: Early deep sedation in the emergency department is common, carries over into the ICU, and may be associated with worse outcomes. Sedation practice in the emergency department and its association with clinical outcomes is in need of further investigation.

Clinical effects of reported synthetic cannabinoid exposure in patients admitted to the intensive care unit.

OBJECTIVE: To characterize the clinical presentation and hospital course of patients with reported synthetic cannabinoid (SC) exposure requiring Intensive Care Unit (ICU) admission. DESIGN: Retrospective case series of patients admitted to medical or cardiac ICU. SETTING: Urban tertiary care center. PARTICIPANTS: Adults ≥18 years old admitted from the emergency department (ED) in 2015. MEASUREMENTS: Demographics, Sequential Organ Failure Assessment (SOFA) scores, and clinical parameters documenting the effects and hospital course. RESULTS: 23 patients met inclusion criteria. Median age was 47 years (interquartile range [IQR], 32-54); 83% male; 78% black. Patients were generally tachycardic (HR > 100), (65%) and hypertensive (SBP > 140), (65%) on admission. The initial chest X-ray and ECG were abnormal in 43% and 68% of patients, respectively. Pulmonary edema and tachycardia were the most common findings. Head CT imaging was abnormal in 5% of patients. Troponin was elevated >1.0 ng/ml in 3 of 19 patients (16%). Other exposures detected on admission were marijuana (30%), alcohol (30%), and benzodiazepines (26%). The median SOFA score was 6 on admission and decreased over the next 3 days. SOFA scores were primarily driven by altered neurologic status and respiratory failure. 91% required mechanical ventilation, 30% had seizures as a part of presentation, 18% required vasopressors, and 5% needed dialysis. Median hospital and ICU lengths of stay were 2.6 (IQR 1.4-3.5) and 1.6 (IQR 0.9-2.5) days, respectively. The median hospital charge was $37,008. All patients survived the index hospitalization. CONCLUSIONS: Patients admitted to ICU after SC exposure exhibit significant organ dysfunction, particularly neurologic and respiratory. Prognosis is good with supportive care.

Sleep Medicine: Parasomnias.

Parasomnias are abnormal and undesirable behaviors during sleep and are thought to be due to the sleep state instability. Some of them are benign, while some of them point to a possible underlying neurodegenerative process. This article briefly discusses the clinical characteristics, demographics, and pathophysiology of major parasomnias and associated disorders. The classification outlined in this article conforms to the current version of International Classification of Sleep disorders.

U.S. drug shortages for medications used in adult critical care (2001-2016).

PURPOSE: We describe trends in U.S. shortages impacting critical care drugs from 2001 to 2016. MATERIALS AND METHODS: Shortages within the scope of critical care were identified using data from the University of Utah Drug Information Services. Shortage characteristics were described using standard descriptive statistics and regression analysis. RESULTS: Of 1969 shortages reported, 1004 (51%) were for drugs used in critical care. New shortages fell from 2001 to 2004, then increased, peaking in 2011 (116). For critical care shortages, 247 (24.6%) involved drugs used for high acuity conditions. The majority of drugs on shortage were parenteral, (720; 71.7%) and 393 (39.1%) were single source drugs. Alternatives were available for 887 (88.3%) drugs, although 250 (24.9%) alternatives were impacted by shortages. Infectious disease drugs were the most common drugs on shortage, with 200 (19.9%) shortages, with a median duration of 7.7months (IQR=2.8-17.3). By the end of the study, 896 (89.2%) shortages were resolved and 108 (10.8%) remained active. The median duration for active shortages was 13.6months (IQR=5.8-58.4) while the duration for resolved shortages was 7.2months (IQR=2.8-17.3). CONCLUSIONS: Although the number of new shortages peaked in 2011 and is now declining, there remain a substantial number of active shortages impacting critical care drugs.
