Abstract
Background: Older adults with cancer use the emergency department (ED) for acute concerns. Objectives: Characterize the palliative care needs and clinical outcomes of advanced cancer patients in the ED. Design: A planned secondary data analysis of the Comprehensive Oncologic Emergencies Research Network (CONCERN) data. Settings/Subjects: Cancer patients who presented to the 18 CONCERN affiliated EDs in the United States. Measurements: Survey included demographics, cancer type, functional status, symptom burden, palliative and hospice care enrollment, and advance directive code status. Results: Of the total (674/1075, 62.3%) patients had advanced cancer and most were White (78.6%) and female (50.3%); median age was 64 (interquartile range 54-71) years. A small proportion of them were receiving palliative (6.5% [95% confidence interval; CI 3.0-7.6]; p = 0.005) and hospice (1.3% [95% CI 1.0-3.2]; p = 0.52) care and had a higher 30-day mortality rate (8.3%, [95% CI 6.2-10.4]). Conclusions: Patients with advanced cancer continue to present to the ED despite recommendations for early delivery of palliative care.

Prospective Validation of a Rapid Host Gene Expression Test to Discriminate Bacterial From Viral Respiratory Infection. JAMA Netw Open 2022; 5:e227299. [PMID: 35420659 PMCID: PMC9011121 DOI: 10.1001/jamanetworkopen.2022.7299] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Accepted: 02/24/2022] [Indexed: 12/24/2022] Open
Abstract
Importance Bacterial and viral causes of acute respiratory illness (ARI) are difficult to clinically distinguish, resulting in the inappropriate use of antibacterial therapy. The use of a host gene expression-based test that is able to discriminate bacterial from viral infection in less than 1 hour may improve care and antimicrobial stewardship. Objective To validate the host response bacterial/viral (HR-B/V) test and assess its ability to accurately differentiate bacterial from viral infection among patients with ARI. Design, Setting, and Participants This prospective multicenter diagnostic study enrolled 755 children and adults with febrile ARI of 7 or fewer days' duration from 10 US emergency departments. Participants were enrolled from October 3, 2014, to September 1, 2019, followed by additional enrollment of patients with COVID-19 from March 20 to December 3, 2020. Clinical adjudication of enrolled participants identified 616 individuals as having bacterial or viral infection. The primary analysis cohort included 334 participants with high-confidence reference adjudications (based on adjudicator concordance and the presence of an identified pathogen confirmed by microbiological testing). A secondary analysis of the entire cohort of 616 participants included cases with low-confidence reference adjudications (based on adjudicator discordance or the absence of an identified pathogen in microbiological testing). Thirty-three participants with COVID-19 were included post hoc. Interventions The HR-B/V test quantified the expression of 45 host messenger RNAs in approximately 45 minutes to derive a probability of bacterial infection. Main Outcomes and Measures Performance characteristics for the HR-B/V test compared with clinical adjudication were reported as either bacterial or viral infection or categorized into 4 likelihood groups (viral very likely [probability score <0.19], viral likely [probability score of 0.19-0.40], bacterial likely [probability score of 0.41-0.73], and bacterial very likely [probability score >0.73]) and compared with procalcitonin measurement. Results Among 755 enrolled participants, the median age was 26 years (IQR, 16-52 years); 360 participants (47.7%) were female, and 395 (52.3%) were male. A total of 13 participants (1.7%) were American Indian, 13 (1.7%) were Asian, 368 (48.7%) were Black, 131 (17.4%) were Hispanic, 3 (0.4%) were Native Hawaiian or Pacific Islander, 297 (39.3%) were White, and 60 (7.9%) were of unspecified race and/or ethnicity. In the primary analysis involving 334 participants, the HR-B/V test had sensitivity of 89.8% (95% CI, 77.8%-96.2%), specificity of 82.1% (95% CI, 77.4%-86.6%), and a negative predictive value (NPV) of 97.9% (95% CI, 95.3%-99.1%) for bacterial infection. In comparison, the sensitivity of procalcitonin measurement was 28.6% (95% CI, 16.2%-40.9%; P < .001), the specificity was 87.0% (95% CI, 82.7%-90.7%; P = .006), and the NPV was 87.6% (95% CI, 85.5%-89.5%; P < .001). When stratified into likelihood groups, the HR-B/V test had an NPV of 98.9% (95% CI, 96.1%-100%) for bacterial infection in the viral very likely group and a positive predictive value of 63.4% (95% CI, 47.2%-77.9%) for bacterial infection in the bacterial very likely group. The HR-B/V test correctly identified 30 of 33 participants (90.9%) with acute COVID-19 as having a viral infection. Conclusions and Relevance In this study, the HR-B/V test accurately discriminated bacterial from viral infection among patients with febrile ARI and was superior to procalcitonin measurement. The findings suggest that an accurate point-of-need host response test with high NPV may offer an opportunity to improve antibiotic stewardship and patient outcomes.

Observation unit use among patients with cancer following emergency department visits: Results of a multicenter prospective cohort from CONCERN. Acad Emerg Med 2021; 29:174-183. [PMID: 34811858 PMCID: PMC10359998 DOI: 10.1111/acem.14392] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 09/08/2021] [Accepted: 09/19/2021] [Indexed: 11/26/2022]
Abstract
PURPOSE Emergency department (ED) visits by patients with cancer frequently end in hospitalization. As concerns about ED and hospital crowding increase, observation unit care may be an important strategy to deliver safe and efficient treatment for eligible patients. In this investigation, we compared the prevalence and clinical characteristics of cancer patients who received observation unit care with those who were admitted to the hospital from the ED. METHODS We performed a multicenter prospective cohort study of patients with cancer presenting to an ED affiliated with one of 18 hospitals of the Comprehensive Oncologic Emergency Research Network (CONCERN) between March 1, 2016 and January 30, 2017. We compared patient characteristics with the prevalence of observation unit care usage, hospital admission, and length of stay. RESULTS Of 1051 enrolled patients, 596 (56.7%) were admitted as inpatients, and 72 (6.9%) were placed in an observation unit. For patients admitted as inpatients, 23.7% had a length of stay ≤2 days. The conversion rate from observation to inpatient was 17.1% (95% CI 14.6-19.4) among those receiving care in an observation unit. The average observation unit length of stay was 14.7 h. Patient factors associated ED disposition to observation unit care were female gender and low Charlson Comorbidity Index. CONCLUSION In this multicenter prospective cohort study, the discrepancy between observation unit care use and short inpatient hospitalization may represent underutilization of this resource and a target for process change.

Determining variable costs in the acute urolithiasis cycle of care through time-driven activity-based costing. Urology 2021; 157:107-113. [PMID: 34391774 DOI: 10.1016/j.urology.2021.05.102] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 05/03/2021] [Accepted: 05/12/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To characterize full cycle of care costs for managing an acute ureteral stone using time-driven activity-based costing. METHODS We defined all phases of care for patients presenting with an acute ureteral stone and built an overarching process map. Maps for sub-processes were constructed through interviews with providers and direct observation of clinical spaces. This facilitated calculation of cost per minute for all aspects of care delivery, which were multiplied by associated process times. These were added to consumable costs to determine cost for each specific step and later aggregated to determine total cost for each sub-process. We compared costs of eight common clinical pathways for acute stone management, defining total cycle of care cost as the sum of all sub-processes that comprised each pathway. RESULTS Cost per sub-process included $920 for emergency department (ED) care, $1665 for operative stent placement, $2368 for percutaneous nephrostomy tube placement, $106 for urology clinic consultation, $238 for preoperative center visit, $4057 for ureteroscopy with laser lithotripsy (URS), $2923 for extracorporeal shock wave lithotripsy, $169 for clinic stent removal, $197 for abdominal x-ray, and $166 for ultrasound. The lowest cost pathway ($1388) was for medical expulsive therapy, whereas the most expensive pathway ($8002) entailed a repeat ED visit prompting temporizing stent placement and interval URS. CONCLUSION We found a high degree of cost variation between care pathways common to management of acute ureteral stone episodes. Reliable cost accounting data and an understanding of variability in clinical pathway costs can inform value-based care redesign as payors move away from pure fee-for-service reimbursement.

Cancer pain management in the emergency department: a multicenter prospective observational trial of the Comprehensive Oncologic Emergencies Research Network (CONCERN). Support Care Cancer 2021; 29:4543-4553. [PMID: 33483789 DOI: 10.1007/s00520-021-05987-3] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Accepted: 01/04/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE Many patients with cancer seek care for pain in the emergency department (ED). Prospective research on cancer pain in this setting has historically been insufficient. We conducted this study to describe the reported pain among cancer patients presenting to the ED, how pain is managed, and how pain may be associated with clinical outcomes. METHODS We conducted a multicenter cohort study on adult patients with active cancer presenting to 18 EDs in the USA. We reported pain scores, response to medication, and analgesic utilization. We estimated the associations between pain severity, medication utilization, and the following outcomes: 30-day mortality, 30-day hospital readmission, and ED disposition. RESULTS The study population included 1075 participants. Those who received an opioid in the ED were more likely to be admitted to the hospital and were more likely to be readmitted within 30 days (OR 1.4 (95% CI: 1.11, 1.88) and OR 1.56 (95% CI: 1.17, 2.07)), respectively. Severe pain at ED presentation was associated with increased 30-day mortality (OR 2.30, 95% CI: 1.05, 5.02), though this risk was attenuated when adjusting for clinical factors (most notably functional status). CONCLUSIONS Patients with severe pain had a higher risk of mortality, which was attenuated when correcting for clinical characteristics. Those patients who required opioid analgesics in the ED were more likely to require admission and were more at risk of 30-day hospital readmission. Future efforts should focus on these at-risk groups, who may benefit from additional services including palliative care, hospice, or home-health services.

Emergence of Extended-Spectrum β-Lactamase Urinary Tract Infections Among Hospitalized Emergency Department Patients in the United States. Ann Emerg Med 2020; 77:32-43. [PMID: 33131912 DOI: 10.1016/j.annemergmed.2020.08.022] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 08/07/2020] [Accepted: 08/11/2020] [Indexed: 02/06/2023]
Abstract
STUDY OBJECTIVE Enterobacteriaceae resistant to ceftriaxone, mediated through extended-spectrum β-lactamases (ESBLs), commonly cause urinary tract infections worldwide, but have been less prevalent in North America. Current US rates are unknown. We determine Enterobacteriaceae antimicrobial resistance rates among US emergency department (ED) patients hospitalized for urinary tract infection. METHODS We prospectively enrolled adults hospitalized for urinary tract infection from 11 geographically diverse university-affiliated hospital EDs during 2018 to 2019. Among participants with culture-confirmed infection, we evaluated prevalence of antimicrobial resistance, including that caused by ESBL-producing Enterobacteriaceae, resistance risk factors, and time to in vitro-active antibiotics. RESULTS Of 527 total participants, 444 (84%) had cultures that grew Enterobacteriaceae; 89 of 435 participants (20.5%; 95% confidence interval 16.9% to 24.5%; 4.6% to 45.4% by site) whose isolates had confirmatory testing had bacteria that were ESBL producing. The overall prevalence of ESBL-producing Enterobacteriaceae infection among all participants with urinary tract infection was 17.2% (95% confidence interval 14.0% to 20.7%). ESBL-producing Enterobacteriaceae infection risk factors were hospital, long-term care, antibiotic exposure within 90 days, and a fluoroquinolone- or ceftriaxone-resistant isolate within 1 year. Enterobacteriaceae resistance rates for other antimicrobials were fluoroquinolone 32.3%, gentamicin 13.7%, amikacin 1.3%, and meropenem 0.3%. Ceftriaxone was the most common empirical antibiotic. In vitro-active antibiotics were not administered within 12 hours of presentation to 48 participants (53.9%) with ESBL-producing Enterobacteriaceae infection, including 17 (58.6%) with sepsis. Compared with other Enterobacteriaceae infections, ESBL infections were associated with longer time to in vitro-active treatment (17.3 versus 3.5 hours). CONCLUSION Among adults hospitalized for urinary tract infection in many US locations, ESBL-producing Enterobacteriaceae have emerged as a common cause of infection that is often not initially treated with an in vitro-active antibiotic.

Video Versus Direct and Augmented Direct Laryngoscopy in Pediatric Tracheal Intubations. Acad Emerg Med 2020; 27:394-402. [PMID: 31617640 DOI: 10.1111/acem.13869] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Revised: 09/25/2019] [Accepted: 10/13/2019] [Indexed: 11/26/2022]
Abstract
OBJECTIVES With respect to first-attempt intubation success, the pediatric literature demonstrates either clinical equipoise or superiority of direct laryngoscopy (DL) when compared to video laryngoscopy (VL). Furthermore, it is unknown how VL compares to DL, when DL is "augmented" by maneuvers, such as optimal external laryngeal manipulation (OELM), upright or ramped positioning, or the use of the bougie. The objective of our study was to compare first-attempt success between VL and all DL, including "augmented DL" for pediatric intubations. METHODS We analyzed the National Emergency Airway Registry database of intubations of patients < 16 years. Variables collected included patient demographics, body habitus, impression of airway difficulty, intubating position, reduced neck mobility, airway characteristics, device, medications, and operator characteristics, adjusted for clustering by center. Primary outcome was the difference in first-attempt success for DL and augmented DL versus VL. Secondary outcomes included adverse events. In a planned sensitivity analysis, a propensity-adjusted analysis for first-attempt success and a subgroup analysis of children < 2 years was also performed. RESULTS Of 625 analyzable pediatric encounters, 294 (47.0%, 95% confidence interval [CI] = 25.1% to 69.0%) were DL; 332 (53.1%, 95% CI = 31.0% to 74.9%) were VL. Median age was 4 years (interquartile range = 1 to 10 years); 225 (36.0%, 95% CI = 30.8% to 41.2%) were < 2 years. Overall first-pass success was 79.6% (95% CI = 74.1% to 84.9%). VL first-pass success was 278/331 (84.0%) versus 219/294 for DL (74.5%), adjusted for clustering (odds ratio [OR] = 1.7, 95% CI = 1.3 to 2.5). Multivariable regression showed that VL yielded a higher odds of first-attempt success than DL augmented by OELM or use of a bougie (adjusted OR = 5.5, 95% CI = 1.7 to 18.1). Propensity-adjusted analyses supported the main results. Subgroup analysis of age < 2 years also demonstrated VL superiority (OR = 2.0, 95% CI = 1.1 to 3.3) compared with DL. Adverse events were comparable in both univariate and multivariable analysis. CONCLUSIONS When compared to DL, VL was associated with higher first-pass success in this pediatric population, even in the subgroup of patients < 2 years, as well as when DL was augmented. There were no differences in adverse effects between DL and VL.

Abstract
OBJECTIVE To determine whether continuous virtual monitoring, an intervention that facilitates patient observation through video technology, can be used to monitor suicide risk in the general hospital and emergency department (ED). METHOD This was a retrospective analysis of a protocol in which select patients on suicide precautions in the general hospital and ED received virtual monitoring between June 2017 and March 2018. The primary outcome was the number of adverse events among patients who received virtual monitoring for suicide risk. Secondary outcomes were the percentage of patients for whom virtual monitoring was discontinued for behavioral reasons and the preference for observation type among nurses. RESULTS 39 patients on suicide precautions received virtual monitoring. There were 0 adverse events (95% confidence interval (CI) = 0.000-0.090). Virtual monitoring was discontinued for behavioral reasons in 4/38 cases for which the reason for terminating was recorded (0.105, 95%CI = 0.029-0.248). We were unable to draw conclusions regarding preference for observation type among nurses due to a low response rate to our survey. CONCLUSIONS Suicide risk can feasibly be monitored virtually in the general hospital or ED when their providers carefully select patients for low impulsivity risk.

Validation of the Emergency Severity Index (Version 4) for the Triage of Adult Emergency Department Patients With Active Cancer. J Emerg Med 2019; 57:354-361. [PMID: 31353265 DOI: 10.1016/j.jemermed.2019.05.023] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Revised: 04/25/2019] [Accepted: 05/06/2019] [Indexed: 11/19/2022]
Abstract
BACKGROUND Patients with active cancer account for a growing percentage of all emergency department (ED) visits and have a unique set of risks related to their disease and its treatments. Effective triage for this population is fundamental to facilitating their emergency care. OBJECTIVES We evaluated the validity of the Emergency Severity Index (ESI; version 4) triage tool to predict ED-relevant outcomes among adult patients with active cancer. METHODS We conducted a prespecified analysis of the observational cohort established by the National Cancer Institute-supported Comprehensive Oncologic Emergencies Research Network's multicenter (18 sites) study of ED visits by patients with active cancer (N = 1075). We used a series of χ2 tests for independence to relate ESI scores with 1) disposition, 2) ED resource use, 3) hospital length of stay, and 4) 30-day mortality. RESULTS Among the 1008 subjects included in this analysis, the ESI distribution skewed heavily toward high acuity (>95% of subjects had an ESI level of 1, 2, or 3). ESI was significantly associated with patient disposition and ED resource use (p values < 0.05). No significant associations were observed between ESI and the non-ED based outcomes of hospital length of stay or 30-day mortality. CONCLUSION ESI scores among ED patients with active cancer indicate higher acuity than the general ED population and are predictive of disposition and ED resource use. These findings show that the ESI is a valid triage tool for use in this population for outcomes directly relevant to ED care.

Near-universal hospitalization of US emergency department patients with cancer and febrile neutropenia. PLoS One 2019; 14:e0216835. [PMID: 31120893 PMCID: PMC6532959 DOI: 10.1371/journal.pone.0216835] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2019] [Accepted: 04/29/2019] [Indexed: 11/18/2022] Open
Abstract
Importance Febrile neutropenia (FN) is the most common oncologic emergency and is among the most deadly. Guidelines recommend risk stratification and outpatient management of both pediatric and adult FN patients deemed to be at low risk of complications or mortality, but our prior single-center research demonstrated that the vast majority (95%) are hospitalized. Objective From a nationwide perspective, to determine the proportion of cancer patients of all ages hospitalized after an emergency department (ED) visit for FN, and to analyze variability in hospitalization rates. Our a priori hypothesis was that >90% of US cancer-associated ED FN visits would end in hospitalization. Design Analysis of data from the Nationwide Emergency Department Sample, 2006–2014. Setting Stratified probability sample of all US ED visits. Participants Inclusion criteria were: (1) Clinical Classification Software code indicating cancer, (2) diagnostic code indicating fever, and (3) diagnostic code indicating neutropenia. We excluded visits ending in transfer. Exposure The hospital at which the visit took place. Main outcomes and measures Our main outcome is the proportion of ED FN visits ending in hospitalization, with an a priori hypothesis of >90%. Our secondary outcomes are: (a) hospitalization rates among subsets, and (b) proportion of variability in the hospitalization rate attributable to which hospital the patient visited, as measured by the intra-class correlation coefficient (ICC). Results Of 348,868 visits selected to be representative of all US ED visits, 94% ended in hospitalization (95% Confidence Interval [CI] 93–94%). Each additional decade of age conferred 1.23x increased odds of hospitalization. Those with private (92%), self-pay (92%), and other (93%) insurance were less likely to be hospitalized than those with public insurance (95%, odds ratios [OR] 0.74–0.76). Hospitalization was least likely at non-metropolitan hospitals (84%, OR 0.15 relative to metropolitan teaching hospitals), and was also less likely at metropolitan non-teaching hospitals (94%, OR 0.64 relative to metropolitan teaching hospitals). The ICC adjusted for hospital random effects and patient and hospital characteristics was 26% (95%CI 23–29%), indicating that 26% of the variability in hospitalization rate was attributable to which hospital the patient visited. Conclusions and relevance Nearly all cancer-associated ED FN visits in the US end in hospitalization. Inter-hospital variation in hospitalization practices explains 26% of the limited variability in hospitalization decisions. Simple, objective tools are needed to improve risk stratification for ED FN patients.

Abstract
BACKGROUND Andexanet alfa is a modified recombinant inactive form of human factor Xa developed for reversal of factor Xa inhibitors. METHODS We evaluated 352 patients who had acute major bleeding within 18 hours after administration of a factor Xa inhibitor. The patients received a bolus of andexanet, followed by a 2-hour infusion. The coprimary outcomes were the percent change in anti-factor Xa activity after andexanet treatment and the percentage of patients with excellent or good hemostatic efficacy at 12 hours after the end of the infusion, with hemostatic efficacy adjudicated on the basis of prespecified criteria. Efficacy was assessed in the subgroup of patients with confirmed major bleeding and baseline anti-factor Xa activity of at least 75 ng per milliliter (or ≥0.25 IU per milliliter for those receiving enoxaparin). RESULTS Patients had a mean age of 77 years, and most had substantial cardiovascular disease. Bleeding was predominantly intracranial (in 227 patients [64%]) or gastrointestinal (in 90 patients [26%]). In patients who had received apixaban, the median anti-factor Xa activity decreased from 149.7 ng per milliliter at baseline to 11.1 ng per milliliter after the andexanet bolus (92% reduction; 95% confidence interval [CI], 91 to 93); in patients who had received rivaroxaban, the median value decreased from 211.8 ng per milliliter to 14.2 ng per milliliter (92% reduction; 95% CI, 88 to 94). Excellent or good hemostasis occurred in 204 of 249 patients (82%) who could be evaluated. Within 30 days, death occurred in 49 patients (14%) and a thrombotic event in 34 (10%). Reduction in anti-factor Xa activity was not predictive of hemostatic efficacy overall but was modestly predictive in patients with intracranial hemorrhage. CONCLUSIONS In patients with acute major bleeding associated with the use of a factor Xa inhibitor, treatment with andexanet markedly reduced anti-factor Xa activity, and 82% of patients had excellent or good hemostatic efficacy at 12 hours, as adjudicated according to prespecified criteria.

The Impact of Video Laryngoscopy on the Clinical Learning Environment of Emergency Medicine Residents: A Report of 14,313 Intubations. AEM EDUCATION AND TRAINING 2019; 3:156-162. [PMID: 31008427 PMCID: PMC6457358 DOI: 10.1002/aet2.10316] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Revised: 11/05/2018] [Accepted: 11/27/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND The introduction of video laryngoscopy (VL) may impact emergency medicine (EM) residents' intubation practices. METHODS We analyzed 14,313 intubations from 11 EM training sites, July 1, 2002, to December 31, 2012, assessing the likelihood of first-attempt success and likelihood of having a second attempt, by rank and device. We determined whether direct laryngoscopy (DL) first-attempt success decreased as VL became more prevalent using a logistic regression model with proportion of encounters initiated with VL at that center in the prior 90 and 365 days as predictors of DL first-attempt success. RESULTS First-attempt success by PGY-1s was 71% (95% confidence interval [CI] = 63% to 78%); PGY-2s, 82% (95% CI = 78% to 86%); and PGY-3+, 89% (95% CI = 85% to 92%). Residents' first-attempt success rate was higher with the C-MAC video laryngoscope (C-MAC) versus DL, 92% versus 84% (risk difference [RD] = 8%, 95% CI = 4% to 11%), but there was no statistical difference between the GlideScope video laryngoscope (GVL) and DL, 80% versus 84% (RD = -4%, 95% CI = -10% to 1%). PGY-1s were more likely to have a second intubation attempt after first-attempt failure with VL versus DL: 32% versus 18% (RD = 14%, 95% CI = 5% to 23%). DL first-attempt success rates did not decrease as VL became more prevalent. CONCLUSIONS First-attempt success increases with training. Interns are more likely to have a second attempt when using VL. The C-MAC may be associated with increased first-attempt success for EM residents compared with DL or GVL. The increasing prevalence of VL is not accompanied by a decrease in DL success.

Abstract
IMPORTANCE Better understanding of the emergency care needs of patients with cancer will inform outpatient and emergency department (ED) management. OBJECTIVE To provide a benchmark description of patients who present to the ED with active cancer. DESIGN, SETTING, AND PARTICIPANTS This multicenter prospective cohort study included 18 EDs affiliated with the Comprehensive Oncologic Emergencies Research Network (CONCERN). Of 1564 eligible patients, 1075 adults with active cancer were included from February 1, 2016, through January 30, 2017. Data were analyzed from February 1 through August 1, 2018. MAIN OUTCOMES AND MEASURES The proportion of patients reporting symptoms (eg, pain, nausea) before and during the ED visit, ED and outpatient medications, most common diagnoses, and suspected infection as indicated by ED antibiotic administration. The proportions observed, admitted, and with a hospital length of stay (LOS) of no more than 2 days were identified. RESULTS Of 1075 participants, mean (SD) age was 62 (14) years, and 51.8% were female. Seven hundred ninety-four participants (73.9%; 95% CI, 71.1%-76.5%) had undergone cancer treatment in the preceding 30 days; 674 (62.7%; 95% CI, 59.7%-65.6%) had advanced or metastatic cancer; and 505 (47.0%; 95% CI, 43.9%-50.0%) were 65 years or older. The 5 most common ED diagnoses were symptom related. Of all participants, 82 (7.6%; 95% CI, 6.1%-9.4%) were placed in observation and 615 (57.2%; 95% CI, 54.2%-60.2%) were admitted; 154 of 615 admissions (25.0%; 95% CI, 21.7%-28.7%) had an LOS of 2 days or less (median, 3 days; interquartile range, 2-6 days). Pain during the ED visit was present in 668 patients (62.1%; 95% CI, 59.2%-65.0%; mean [SD] pain score, 6.4 [2.6] of 10.0) and in 776 (72.2%) during the prior week. Opioids were administered in the ED to 228 of 386 patients (59.1%; 95% CI, 18.8%-23.8%) with moderate to severe ED pain. Outpatient opioids were prescribed to 368 patients (47.4%; 95% CI, 3.14%-37.2%) of those with pre-ED pain, including 244 of 428 (57.0%; 95% CI, 52.2%-61.8%) who reported quite a bit or very much pain. Nausea in the ED was present in 336 (31.3%; 95% CI, 28.5%-34.1%); of these, 160 (47.6%; 95% CI, 12.8%-17.1%) received antiemetics in the ED. Antibiotics were administered in the ED to 285 patients (26.5%; 95% CI, 23.9%-29.2%). Of these, 209 patients (73.3%; 95% CI, 17.1%-21.9%) were admitted compared with 427 of 790 (54.1%; 95% CI, 50.5%-57.6%) not receiving antibiotics. CONCLUSIONS AND RELEVANCE This initial prospective, multicenter study profiling patients with cancer who were treated in the ED identifies common characteristics in this patient population and suggests opportunities to optimize care before, during, and after the ED visit. Improvement requires collaboration between specialists and emergency physicians optimizing ED use, improving symptom control, avoiding unnecessary hospitalizations, and appropriately stratifying risk to ensure safe ED treatment and disposition of patients with cancer.

Nonspecific Symptoms Lack Diagnostic Accuracy for Infection in Older Patients in the Emergency Department. J Am Geriatr Soc 2018; 67:484-492.

Abstract
OBJECTIVES To determine if nonspecific symptoms and fever affect the posttest probability of acute bacterial infection in older patients in the emergency department (ED). DESIGN Preplanned, secondary analysis of a prospective observational study. SETTING Tertiary care, academic ED. PARTICIPANTS A total of 424 patients in the ED, 65 years or older, including all chief complaints. MEASUREMENTS We identified presence of altered mental status, malaise/lethargy, and fever, as reported by the patient, as documented in the chart, or both. Bacterial infection was adjudicated by agreement among two or more of three expert reviewers. Odds ratios were calculated using univariable logistic regression. Positive and negative likelihood ratios (PLR and NLR, respectively) were used to determine each symptom's effect on posttest probability of infection. RESULTS Of 424 subjects, 77 (18%) had bacterial infection. Accounting for different reporting methods, presence of altered mental status (PLR range, 1.40-2.53) or malaise/lethargy (PLR range, 1.25-1.34) only slightly increased posttest probability of infection. Their absence did not assist with ruling out infection (NLR, greater than 0.50 for both). Fever of 38°C or higher either before or during the ED visit had moderate to large increases in probability of infection (PLR, 5.15-18.10), with initial fever in the ED perfectly predictive, but absence of fever did not rule out infection (NLR, 0.79-0.92). Results were similar when analyzing lower respiratory, gastrointestinal, and urinary tract infections (UTIs) individually. Of older adults diagnosed as having UTIs, 47% did not complain of UTI symptoms. CONCLUSIONS The presence of either altered mental status or malaise/lethargy does not substantially increase the probability of bacterial infection in older adults in the ED and should not be used alone to indicate infection in this population. Fever of 38°C or higher is associated with increased probability of infection. J Am Geriatr Soc 67:484-492, 2019.

Emergency Department Adult Fiberoptic Intubations: Incidence, Indications, and Implications for Training. Acad Emerg Med 2018; 25:1263-1267. [PMID: 29701889 DOI: 10.1111/acem.13440] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2018] [Revised: 04/02/2018] [Accepted: 04/12/2018] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The objective was to describe the frequency, indications, and outcomes of flexible fiberoptic intubations (FFI) performed in the emergency department (ED). METHODS From the National Emergency Airway Registry (NEAR), we identified all encounters from July 1, 2002, through December 31, 2012, with the use of FFI. We determined patient, provider, and intubation characteristics; success and failure rates; and modes of intubation rescue. RESULTS Among 17,910 intubations of patients > 15 years old at 13 EDs, FFI was used in 204 cases (1.1%, 95% confidence interval [CI] = 0.26%-2.0%). FFI was the first method chosen (primary FFI) in 180 encounters (1%, 95% CI = 0.2%-1.8%). The most common indication for FFI was airway obstruction (36.1%, 95% CI = 24.6%-47.7%). For primary FFI, first-attempt intubation success was 51.1% (95% CI = 43.6%-58.6%), and overall intubation success with FFI was 74.3% (95% CI = 65.7%-82.9%). FFI was used as a rescue airway strategy in 24 cases (0.1% of all encounters) and was successful in 17 of those (70.8%, 95% CI = 65.4%-85.2%). CONCLUSIONS Emergency department FFI is uncommon and typically used as a nonsurgical alternative for airway obstruction. First-attempt ED FFI is successful in half of cases and in two-thirds of rescue attempts. These data provide an important baseline to help better characterize the nature of FFI as a rare critical procedure in the ED and offer an empiric basis for ongoing discussions on the optimal role of FFI in ED training and practice.

Immune-related Adverse Events in Cancer Patients. Acad Emerg Med 2018; 25:819-827. [PMID: 29729100 DOI: 10.1111/acem.13443] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2018] [Revised: 03/28/2018] [Accepted: 04/23/2018] [Indexed: 12/17/2022]
Abstract
The U.S. Food and Drug Administration has approved immune checkpoint inhibitors and chimeric antigen receptor T cells (CAR-T cells) as immunotherapy strategies for cancer. These therapies cause a wide variety of adverse events, which mimic other disease states and may emerge months after completion of treatment. This is important because ascertaining a past medical history of cancer treatment within the past year becomes necessary for many presentations. This narrative review summarizes the biology, pathophysiology, and adverse events associated with checkpoint inhibitors and CAR-T cells and provides a rational approach to management. Proper treatment begins with heightened awareness, rapid diagnosis, and discussion with the patient's oncologist. Treatment of these adverse effects requires only corticosteroids, infliximab, tocilizumab, or fluids or vasopressors when clinically indicated.

Integrative omics to detect bacteremia in patients with febrile neutropenia. PLoS One 2018; 13:e0197049.

Abstract
BACKGROUND Cancer chemotherapy-associated febrile neutropenia (FN) is a common condition that is deadly when bacteremia is present. Detection of bacteremia depends on culture, which takes days, and no accurate predictive tools applicable to the initial evaluation are available. We utilized metabolomics and transcriptomics to develop multivariable predictors of bacteremia among FN patients. METHODS We classified emergency department patients with FN and no apparent infection at presentation as bacteremic (cases) or not (controls), according to blood culture results. We assessed relative metabolite abundance in plasma, and relative expression of 2,560 immunology and cancer-related genes in whole blood. We used logistic regression to identify multivariable predictors of bacteremia, and report test characteristics of the derived predictors. RESULTS For metabolomics, 14 bacteremic cases and 25 non-bacteremic controls were available for analysis; for transcriptomics we had 7 and 22 respectively. A 5-predictor metabolomic model had an area under the receiver operating characteristic curve of 0.991 (95%CI: 0.972,1.000), 100% sensitivity, and 96% specificity for identifying bacteremia. Pregnenolone steroids were more abundant in cases and carnitine metabolites were more abundant in controls. A 3-predictor gene expression model had corresponding results of 0.961 (95%CI: 0.896,1.000), 100%, and 86%. Genes involved in innate immunity were differentially expressed. CONCLUSIONS Classifiers derived from metabolomic and gene expression data hold promise as objective and accurate predictors of bacteremia among FN patients without apparent infection at presentation, and can provide insights into the underlying biology. Our findings should be considered illustrative, but may lay the groundwork for future biomarker development.

Abstract
Importance Many inflammatory skin dermatoses mimic cellulitis (pseudocellulitis) and are treated with antibiotics and/or hospitalization, leading to unnecessary patient morbidity and substantial health care spending. Objective To evaluate the impact of early dermatology consultation on clinical and economic outcomes associated with misdiagnosed cellulitis. Design, Setting, and Participants This prospective cohort study enrolled patients with presumed diagnosis of cellulitis in the emergency department, in the emergency department observation unit, or within 24 hours of admission to an inpatient unit of a large urban teaching hospital between February and September 2017. Patients were provided with telephone and clinic follow-up during the 30-day postdischarge period. We screened 165 patients with the primary concern of cellulitis. Of these, we excluded 44 who required antibiotics for cutaneous, soft-tissue, and deeper-tissue and/or bone infections irrespective of cellulitis status, and 5 who were scheduled to be discharged by the emergency department. Interventions Early dermatology consultation for presumed cellulitis. Main Outcomes and Measures Primary outcomes were patient disposition and rates of antibiotic use. Results Of 116 patients (63 [54.3%] women; 91 [78.4%] non-Hispanic white; mean [SD] age, 58.4 [19.1] years), 39 (33.6%) were diagnosed with pseudocellulitis by dermatologists. Of these, 34 (87.2%) had started using antibiotics for presumed cellulitis as prescribed by the primary team at the time of enrollment. The dermatology team recommended antibiotic discontinuation in 28 of 34 patients (82.4%), and antibiotics were stopped in 26 of 28 cases (92.9%). The dermatologists also recommended discharge from planned observation or inpatient admission in 20 of 39 patients with pseudocellulitis (51.3%), and the primary team acted on this recommendation in 17 of 20 cases (85.0%). No patients diagnosed with pseudocellulitis experienced worsening condition after discharge based on phone and clinic follow-up (30 of 39 [76.9%] follow-up rate). Extrapolating the impact of dermatology consultation for presumed cellulitis nationally, we estimate 97 000 to 256 000 avoided hospitalization days, 34 000 to 91 000 patients avoiding unnecessary antibiotic exposure, and $80 million to $210 million in net cost savings annually. Conclusions and Relevance Early consultation by dermatologists for patients with presumed cellulitis represents a cost-effective intervention to improve health-related outcomes through the reduction of inappropriate antibiotic use and hospitalization.

Comparing Ran-Out Status of Inhaled Short-Acting Beta-Agonists in Emergency Department Patients with Acute Asthma: 1996-1998 versus 2015-2017. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2018; 6:1999-2005.e3. [PMID: 29653218 DOI: 10.1016/j.jaip.2018.04.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 03/27/2018] [Accepted: 04/02/2018] [Indexed: 12/25/2022]
Abstract
BACKGROUND Medication nonadherence, including running out of inhaled asthma medications, is an important problem. OBJECTIVE The objective of this study was to examine the changes in the proportion of adults with acute asthma who ran out of their short-acting beta-agonist (SABA) inhalers before presenting to the emergency department (ED) between 1996--1998 and 2015-2017. METHODS We analyzed data from prospective multicenter observational cohort studies of ED adult patients (aged 18-54 years) with acute asthma. Within the same 3 EDs, we performed a structured interview during 2 time periods: 1996-1998 and 2015-2017. We fitted multivariable models to compare ran-out status between the 2 periods, adjusting for the baseline patient demographics, socioeconomic status, chronic asthma factors, and health care utilization factors. We further adjusted for the presence of a written action plan-an intervenable factor. RESULTS The analytic cohort comprised 353 patients (150 from the 1996-1998 studies and 203 from the 2015-2017 study). Over the approximately 20-year period, the proportion of patients who ran out of SABA inhalers increased (18% in 1996-1998 vs 26% in 2015-2017). In the multivariable model, compared with patients in 1996-1998, those in 2015-2017 had a significantly higher risk of running out of their SABA inhalers (adjusted odds ratio [OR] 2.01; 95% confidence interval [CI] 1.06-3.81; P = .03). With further adjustment for the presence of a written action plan, this difference attenuated (adjusted OR 1.66; 95% CI 0.75-3.68; P = .21). CONCLUSIONS Between 1996 and 2017, the proportion of ED patients with asthma who ran out of SABA inhalers significantly increased. The increase was explained, at least partially, by a lack of a written action plan.

Abstract
OBJECTIVES To inform the shared decision-making process between clinicians and older adults and their surrogates regarding emergency intubation. DESIGN Retrospective cohort study. SETTING Multicenter, emergency department (ED)-based cohort. PARTICIPANTS Adults aged 65 and older intubated in the ED from 2008 to 2015 from 262 hospitals across the United States (>95% of U.S. nonprofit academic medical centers). MEASUREMENTS Our primary outcome was age-specific in-hospital mortality. Secondary outcomes were age-specific odds of death after adjusting for race, comorbid conditions, admission diagnosis, hospital disposition, and geographic region. RESULTS We identified 41,463 ED intubation encounters and included 35,036 in the final analysis. Sixty-four percent were in non-Hispanic whites and 54% in women. Overall in-hospital mortality was 33% (95% confidence interval (CI)=34-35%). Twenty-four percent (95% CI=24-25%) of subjects were discharged to home, and 41% (95% CI=40-42%) were discharged to a location other than home. Mortality was 29% (95% CI=28-29%) for individuals aged 65 to 74, 34% (95% CI=33-35%) for those aged 75 to 79, 40% (95% CI=39-41%) for those aged 80 to 84, 43% (95% CI=41-44%) for those aged 85 to 89, and 50% (95% CI=48-51%) for those aged 90 and older. CONCLUSION After emergency intubation, 33% percent of older adults die during the index hospitalization. Only 24% of survivors are discharged to home. Simple, graphic representations of this information, in combination with an experienced clinician's overall clinical assessment, will support shared decision-making regarding unplanned intubation.

Clinical Severity Alone Does Not Determine Disposition Decisions for Patients in the Emergency Department with Suicide Risk. PSYCHOSOMATICS 2017; 59:388-393.

Abstract
BACKGROUND Boarding of patients with suicide risk in emergency departments (EDs) negatively affects both patients and society. Factors other than clinical severity may frequently preclude safe outpatient dispositions among suicidal patients boarding for psychiatric admission in the ED. OBJECTIVE To determine the extent to which nonclinical factors preclude safe outpatient discharge from the ED among patients boarding for psychiatric admission based on suicide risk. METHODS A survey regarding the importance of 13 clinical and 19 nonclinical barriers to safe outpatient disposition was administered in the ED to 40 adults who were determined by psychiatrists to require inpatient level of psychiatric care due to suicide risk. A second survey regarding whether addressing the nonclinical factors would have enabled a safe outpatient disposition in each case was administered to the psychiatrists who evaluated each patient participant. RESULTS Out of 40 patient participants, 39 cited at least one nonclinical factor that could have enabled a safe outpatient disposition had it been correctable in the ED. According to the psychiatrists who made the decision to hospitalize, 10 (25%) of the patient participants could have been discharged had social support become available. CONCLUSION Both clinical and nonclinical factors affect disposition from the ED after an evaluation for suicide risk. Attention to nonclinical factors should be considered in programmatic efforts to reduce ED boarding of patients with suicide risk.

Abstract
BACKGROUND Fever is common among intensive care unit (ICU) patients. Clinicians may use microbiological cultures to differentiate infectious and aseptic fever. However, their utility depends on the prevalence of infection; and false-positive results might adversely affect patient care. We sought to quantify the cost and utility of microbiological cultures in a cohort of ICU patients with spontaneous intracerebral hemorrhage (ICH). METHODS We performed a secondary analysis of a cohort with spontaneous ICH requiring mechanical ventilation. We collected baseline data, measures of systemic inflammation, microbiological culture results for the first 48 h, and daily antibiotic usage. Two physicians adjudicated true-positive and false-positive culture results using standard criteria. We calculated the cost per true-positive result and used logistic regression to test the association between false-positive results with subsequent antibiotic exposure. RESULTS Overall, 697 subjects were included. A total of 233 subjects had 432 blood cultures obtained, with one true-positive (diagnostic yield 0.1 %, $22,200 per true-positive) and 11 false-positives. True-positive urine cultures (5 %) and sputum cultures (13 %) were more common but so were false-positives (6 and 17 %, respectively). In adjusted analysis, false-positive blood and sputum results were associated with increased antibiotic exposure. CONCLUSIONS The yield of blood cultures early after spontaneous ICH was very low. False-positive results significantly increased the odds of antibiotic exposure. Our results support limiting the use of blood cultures in the first two days after ICU admission for spontaneous ICH.

Abstract
OBJECTIVES To compare the accuracy of the Loeb criteria, emergency department (ED) physicians' diagnoses, and Centers for Disease Control and Prevention (CDC) guidelines for acute bacterial infection in older adults with a criterion standard expert review. DESIGN Prospective, observational study. SETTING Urban, tertiary-care ED. PARTICIPANTS Individuals aged 65 and older in the ED, excluding those who were incarcerated, underwent a trauma, did not speak English, or were unable to consent. MEASUREMENTS Two physician experts identified bacterial infections using clinical judgement, participant surveys, and medical records; a third adjudicated in cases of disagreement. Agreement and test characteristics were measured for ED physician diagnosis, Loeb criteria, and CDC surveillance guidelines. RESULTS Criterion-standard review identified bacterial infection in 77 of 424 participants (18%) (18 (4.2%) lower respiratory, 19 (4.5%) urinary tract (UTI), 22 (5.2%) gastrointestinal, 15 (3.5%) skin and soft tissue). ED physicians diagnosed infection in 71 (17%), but there were 33 with under- and 27 with overdiagnosis. Physician agreement with the criterion standard was moderate for infection overall and each infection type (κ = 0.48-0.59), but sensitivity was low (<67%), and the negative likelihood ratio (LR(-)) was greater than 0.30 for all infections. The Loeb criteria had poor sensitivity, agreement, and LR(-) for lower respiratory (50%, κ = 0.55; 0.51) and urinary tract infection (26%, κ = 0.34; 0.74), but 87% sensitivity (κ = 0.78; LR(-) 0.14) for skin and soft tissue infections. CDC guidelines had moderate agreement but poor sensitivity and LR(-). CONCLUSION Emergency physicians often under- and overdiagnose infections in older adults. The Loeb criteria are useful only for diagnosing skin and soft tissue infections. CDC guidelines are inadequate in the ED. New criteria are needed to aid ED physicians in accurately diagnosing infection in older adults.

Index to Predict In-hospital Mortality in Older Adults after Non-traumatic Emergency Department Intubations. West J Emerg Med 2017; 18:690-697. [PMID: 28611890 PMCID: PMC5468075 DOI: 10.5811/westjem.2017.2.33325] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2016] [Revised: 02/10/2017] [Accepted: 02/15/2017] [Indexed: 02/06/2023] Open
Abstract
INTRODUCTION Our goal was to develop and validate an index to predict in-hospital mortality in older adults after non-traumatic emergency department (ED) intubations. METHODS We used Vizient administrative data from hospitalizations of 22,374 adults ≥75 years who underwent non-traumatic ED intubation from 2008-2015 at nearly 300 U.S. hospitals to develop and validate an index to predict in-hospital mortality. We randomly selected one half of participants for the development cohort and one half for the validation cohort. Considering 25 potential predictors, we developed a multivariable logistic regression model using least absolute shrinkage and selection operator method to determine factors associated with in-hospital mortality. We calculated risk scores using points derived from the final model's beta coefficients. To evaluate calibration and discrimination of the final model, we used Hosmer-Lemeshow chi-square test and receiver-operating characteristic analysis and compared mortality by risk groups in the development and validation cohorts. RESULTS Death during the index hospitalization occurred in 40% of cases. The final model included six variables: history of myocardial infarction, history of cerebrovascular disease, history of metastatic cancer, age, admission diagnosis of sepsis, and admission diagnosis of stroke/ intracranial hemorrhage. Those with low-risk scores (<6) had 31% risk of in-hospital mortality while those with high-risk scores (>10) had 58% risk of in-hospital mortality. The Hosmer-Lemeshow chi-square of the model was 6.47 (p=0.09), and the c-statistic was 0.62 in the validation cohort. CONCLUSION The model may be useful in identifying older adults at high risk of death after ED intubation.

Management of Major Bleeding Events in Patients Treated With Dabigatran for Nonvalvular Atrial Fibrillation: A Retrospective, Multicenter Review. Ann Emerg Med 2017; 69:531-540. [PMID: 28196608 PMCID: PMC5568766 DOI: 10.1016/j.annemergmed.2016.11.040] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2016] [Revised: 11/20/2016] [Accepted: 11/23/2016] [Indexed: 01/14/2023]
Abstract
Study objective There are limited data on the clinical presentations and management of dabigatran-associated major bleeding outside the clinical trial setting. The aim of this study is to describe clinical characteristics, interventions, and outcomes in patients with dabigatran-associated major bleeding who present to the emergency department (ED). Methods We performed a retrospective observational chart review study of dabigatran-treated patients with nonvalvular atrial fibrillation who presented with acute major bleeding to the ED. We searched electronic medical record databases cross-referencing medication lists and hemorrhage International Classification of Diseases, Ninth Revision (ICD-9) and ICD-10 codes. We studied the resulting charts to yield confirmed nonvalvular atrial fibrillation in patients with an index event of major bleeding and at least 1 dose of dabigatran in the 5 preceding days. Results The electronic search yielded 284 cases, and we assessed 93 as ineligible, leaving 191 in the final cohort. Of these, 118 patients (62%) had gastrointestinal hemorrhage; 36 (19%) had intracranial hemorrhage, 8 (4%) of which were nontraumatic cases and 28 (15%) traumatic. Thirty-six (19%) of the index events were in “other” locations and 1 (0.5%) “unknown.” There were 12 deaths (6%): 8 from patients presenting with gastrointestinal bleeding events, 2 from intracranial hemorrhage (both nontraumatic), and 2 from other. Although RBC and plasma transfusions were common, only 11 patients (6%) received purified coagulation factors. Conclusion Despite rare use of reversal strategies, mortality was low and outcomes were favorable, similar to reported outcomes from clinical trials, in this sample of patients with major bleeding while receiving dabigatran.

Emergency Department Management of Patients With Febrile Neutropenia: Guideline Concordant or Overly Aggressive? Acad Emerg Med 2017; 24:83-91. [PMID: 27611638 DOI: 10.1111/acem.13079] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2016] [Revised: 08/08/2016] [Accepted: 08/15/2016] [Indexed: 12/23/2022]
Abstract
OBJECTIVES The Infectious Diseases Society of America and the American Society of Clinical Oncology recommend risk stratification of patients with febrile neutropenia (FN) and discharge with oral antibiotics for low-risk patients. We studied guideline concordance and clinical outcomes of FN management in our emergency department (ED). METHODS Our urban, tertiary care teaching hospital provides all emergency and inpatient services to a large comprehensive cancer center. We performed a structured chart review of all FN patients seen in our ED from January 2010 to December 2014. Using electronic medical records, we identified all visits by patients with fever and an absolute neutrophil count of <1000 cells/mm3 and then included only patients without a clear source of infection. Following national guidelines, we classified patients as low or high risk and assessed guideline concordance in disposition and parenteral versus oral antibiotic therapy by risk category as our main outcome measure. RESULTS Of 173 qualifying visits, we classified 44 (25%) as low risk and 129 (75%) as high risk. Management was guideline concordant in 121 (70%, 95% confidence interval [CI] = 63% to 77%). Management was guideline discordant in 43 (98%, 95% CI = 88% to 100%) of low-risk patients versus 9 (7%, 95% CI = 3% to 13%) of high-risk patients (relative risk [RR] = 14, 95% CI = 7.5 to 26). Of 52 guideline-discordant cases, 36 (83%, 95% CI = 72% to 93%) involved low-risk cases with treatment that was more aggressive than recommended. CONCLUSIONS Guideline concordance was low among low-risk patients, with management tending to be more aggressive than recommended. Unless data emerge that undermine the guidelines, we believe that many of these hospitalizations and parenteral antibiotic regimens can be avoided, decreasing the risks associated with hospitalization, while improving antibiotic stewardship and patient comfort.

Toward an Objective Diagnostic Test for Bacterial Cellulitis. PLoS One 2016; 11:e0162947. [PMID: 27656884 PMCID: PMC5033594 DOI: 10.1371/journal.pone.0162947] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2016] [Accepted: 08/31/2016] [Indexed: 11/24/2022] Open
Abstract
Background Prior studies repeatedly showed that cultures of skin lesions diagnosed as "cellulitis" are usually negative. However, lack of a gold standard for diagnosis (against which culture might be judged) and failure to assess the human immune response are important limitations of prior work. In this pilot study, we aimed to develop a criterion standard for research on bacterial cellulitis, to evaluate the sensitivity of procalcitonin for bacterial cellulitis, and to use gene expression analysis to find other candidate diagnostic markers. Methods We classified lesions via biopsies, 16s rRNA gene detection, culture, and histopathology. We quantified procalcitonin expression in blood. We also used Nanostring technology to quantify transcription of immunomodulators that may distinguish cases from inflamed controls. Results Of 28 participants, 15 had a clinical diagnosis of cellulitis, six had a diagnosis of non-infectious dermatitis, and seven were normal volunteers. Of the “cellulitis” patients, three (20%) had pathogens isolated, and were designated confirmed cases. Procalcitonin was undetectable in all three. HLA-DQA1 was expressed 34-fold more in confirmed cases vs. controls (fold change of geometric mean). Heat maps depicting multiplex gene expression analysis revealed a distinct profile of gene expression in confirmed cases relative to comparators. Conclusions Most “cellulitis” patients had microbiologically-negative biopsies. Procalcitonin was undetectable, and HLA-DQA1 elevated, in confirmed bacterial cases. Multivariable transcriptomic profiling results supported our algorithm’s ability to identify patients with true bacterial cellulitis. A larger sample may allow discovery of an immunological signature capable of distinguishing bacterial cellulitis from its mimics in clinical practice.

Failure of antibiotics in cellulitis trials: a systematic review and meta-analysis. Am J Emerg Med 2016; 34:1645-52. [PMID: 27344098 DOI: 10.1016/j.ajem.2016.05.064] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Accepted: 05/21/2016] [Indexed: 12/20/2022] Open
Abstract
OBJECTIVES The objectives of the study are to quantify trial-to-trial variability in antibiotic failure rates, in randomized clinical trials of cellulitis treatment and to provide a point estimate for the treatment failure rate across trials. METHODS We conducted a structured search for clinical trials evaluating antibiotic treatment of cellulitis, indexed in PubMed by August 2015. We included studies published in English and excluded studies conducted wholly outside of developed countries because the pathophysiology of cellulitis is likely to be different in such settings. Two authors reviewed all abstracts identified for possible inclusion. Of studies identified initially, 5% met the selection criteria. Two reviewers extracted data independently, and data were pooled using the Freeman-Tukey transformation under a random-effects model. Our primary outcome was the summary estimate of treatment failure across intent-to-treat and clinically evaluable participants. RESULTS We included 19 articles reporting data from 20 studies, for a total of 3935 patients. Treatment failure was reported in 6% to 37% of participants in the 9 trials reporting intent-to-treat results, with a summary point estimate of 18% failing treatment (95% confidence interval, 15%-21%). In the 15 articles evaluating clinically evaluable participants, treatment failure rates ranged from 3% to 42%, and overall, 12% (95% confidence interval, 10%-14%) were designated treatment failures. CONCLUSIONS Treatment failure rates vary widely across cellulitis trials, from 6% to 37%. This may be due to confusion of cellulitis with its mimics and perhaps problems with construct validity of the diagnosis of cellulitis. Such factors bias trials toward equivalence and, in routine clinical care, impair quality and antibiotic stewardship. Objective diagnostic tools are needed.

Abstract
Contact precautions policies in US emergency departments have not been studied. We surveyed a structured random sample and found wide variation; for example, 45% required contact precautions for stool incontinence or diarrhea, 84% for suspected Clostridium difficile, and 79% for suspected methicillin-resistant Staphylococcus aureus infection. Emergency medicine departments and organizations should enact policies.

Abstract
Introduction Nothing has been published to describe the practices of medical societies in choosing abstracts for presentations at their annual meetings. We surveyed medical societies to determine their practices, and also present a theoretical analysis of the topic. Methods We contacted a convenience sample of large U.S. medical conferences, and determined their approach to choosing abstracts. We obtained information from web sites, telephone, and email. Our theoretical analysis compares values-based and empirical approaches for scoring system development. Results We contacted 32 societies and obtained data on 28 (response rate 88%). We excluded one upon learning that research was not presented at its annual meeting, leaving 27 for analysis. Only 2 (7%) made their abstract scoring process available to submitters. Reviews were blinded in most societies (21;78%), and all but one asked reviewers to recuse themselves for conflict of interest (96%). All required ≥3 reviewers. Of the 24 providing information on how scores were generated, 21 (88%) reported using a single gestalt score, and three used a combined score created from pooled domain-specific sub-scores. We present a framework for societies to use in choosing abstracts, and demonstrate its application in the development of a new scoring system. Conclusions Most medical societies use subjective, gestalt methods to select research for presentation at their annual meetings and do not disclose to submitters the details of how abstracts are chosen. We present a new scoring system that is transparent to submitters and reviewers alike with an accompanying statement of values and ground rules. We discuss the challenges faced in selecting abstracts for a large scientific meeting and share the values and practical considerations that undergird the new system.

Abstract
BACKGROUND Comprehensive data that address current HIV nonoccupational postexposure prophylaxis (nPEP) practices in the emergency care of sexual assault patients are limited. The U.S. Centers for Disease Control and Prevention released HIV nPEP guidelines in 2005 and updated guidelines for Sexually Transmitted Disease Treatment in 2006 and 2010, each of which support providing nPEP to sexual assault patients. This study examined the offer, acceptance, and adherence rates of nPEP among sexual assault patients treated at an emergency department (ED). METHODS We conducted a retrospective review between January 1, 2008, and December 31, 2011, of women, aged 16 years and older, treated for sexual assault in an academic ED that participates in the sexual assault nurse examiner program. FINDINGS One hundred seventy-one female patients were treated in the ED for 179 sexual assault events. nPEP was not indicated in 19 cases and was offered to all 138 of patients for whom nPEP was appropriate. Five patient cases that exceeded the 72-hour exposure window were offered nPEP. Of the 143 patient cases offered nPEP, 124 (86.7%) initiated nPEP. Of the 124 who accepted PEP, 34 (27.4%) had documented completion of the 28-day course. CONCLUSIONS nPEP was offered in all 138 cases where patients were eligible for treatment. Of patients who accepted nPEP, a minority are documented to have completed a course of treatment. Systems to improve postassault follow-up care should be considered.

Abstract
The US Food and Drug Administration has scrutinized clinical trial methodology in cellulitis, partly because the definition and timing of cure are debatable. We analysed the validity of telephone self-report as a proxy for in-person follow up in a cellulitis treatment trial comparing cephalexin alone with cephalexin-plus-trimethoprim/sulfamethoxazole. Our results demonstrate poor agreement between these two methods of outcome determination and have implications for future cellulitis clinical trial design and clinical management.

Abstract
Background Photographs are important tools to record, track, and communicate clinical findings. Mobile devices with high-resolution cameras are now ubiquitous, giving clinicians the opportunity to capture and share images from the bedside. However, secure and efficient ways to manage and share digital images are lacking. Objective The aim of this study is to describe the implementation of a secure application for capturing and storing clinical images in the electronic health record (EHR), and to describe initial user experiences. Methods We developed CliniCam, a secure Apple iOS (iPhone, iPad) application that allows for user authentication, patient selection, image capture, image annotation, and storage of images as a Portable Document Format (PDF) file in the EHR. We leveraged our organization’s enterprise service-oriented architecture to transmit the image file from CliniCam to our enterprise clinical data repository. There is no permanent storage of protected health information on the mobile device. CliniCam also required connection to our organization’s secure WiFi network. Resident physicians from emergency medicine, internal medicine, and dermatology used CliniCam in clinical practice for one month. They were then asked to complete a survey on their experience. We analyzed the survey results using descriptive statistics. Results Twenty-eight physicians participated and 19/28 (68%) completed the survey. Of the respondents who used CliniCam, 89% found it useful or very useful for clinical practice and easy to use, and wanted to continue using the app. Respondents provided constructive feedback on location of the photos in the EHR, preferring to have photos embedded in (or linked to) clinical notes instead of storing them as separate PDFs within the EHR. Some users experienced difficulty with WiFi connectivity which was addressed by enhancing CliniCam to check for connectivity on launch. Conclusions CliniCam was implemented successfully and found to be easy to use and useful for clinical practice. CliniCam is now available to all clinical users in our hospital, providing a secure and efficient way to capture clinical images and to insert them into the EHR. Future clinical image apps should more closely link clinical images and clinical documentation and consider enabling secure transmission over public WiFi or cellular networks.

Abstract
STUDY OBJECTIVE Compare outcomes among emergency department (ED) patients with low-positive (0.01-0.02 ng/mL) vs negative troponin T. METHODS Retrospective cohort study of nonadmitted ED patients with troponin testing at a tertiary-care hospital. Trained research assistants used a structured tool to review charts from all nonadmitted ED patients with troponin testing, 12/1/2009 to 11/30/2010. Outcomes of death and coronary revascularization were assessed at 30 days and 6 months via medical record review, Social Security Death Index searches, and patient contact. RESULTS There were 57596 ED visits; with 33388 (58%) discharged immediately, 6410 (11%) assigned to the observation unit, and 17798 (31%) admitted or other. Troponin was measured in 2684 (6.7%) of the nonadmitted cases. Troponin was negative in 2523 (94.0%), low positive in 78 (2.9%), and positive (≥0.03 ng/mL) in 83 (3.1%). Of troponin-negative cases, 0.8% (95% CI, 0.4-1.1%) died or were revascularized by 30 days, vs 2.8% (95% CI, 0.0-6.7%) of low-positive cases (risk difference [RD], 2.0%; 95% CI, -1.8 to 5.9%). At 6 months, the rates were 1.7% (95% CI, 1.1-2.2%) and 12.9% (95% CI, 5.0-20.7%) (RD, 11%; 95% CI, 3.3-19.1%). Death alone at 30 days occurred in 0.4% (95% CI, 0.1-0.6%) vs 1.3% (95% CI, 0.0-3.8%) (RD, 0.9%; 95% CI, -1.6 to 3.4%). Death at 6 months occurred in 1.2% (95% CI, 0.8-1.6%) vs 11.7% (95% CI, 4.5-18.9%) (RD, 10%; 95% CI, 3.3-17.7%). CONCLUSION Among patients not initially admitted, rates of death and coronary revascularization differed insignificantly at 30 days but significantly at 6 months. Detailed inspection of our results reveals that the bulk of the added risk at 6 months was due to non-cardiac mortality.

Abstract
Background. Rapid urine tests for infection (urinalysis, dipstick) have low up-front costs. However, many false positives occur, with important downstream consequences, including unnecessary antibiotics. We studied indications, collection technique, and results of urinalyses in acute care. Methods. This research was a prospective observational study of a convenience sample of emergency department (ED) patients who had urinalysis performed between June 1, 2012 and February 15, 2013 at an urban teaching hospital. Analyses were conducted via t tests, χ2 tests, and multivariable logistic regression. Results. Of 195 cases included in the study, the median age was 56 and 70% of participants were female. There were specific symptoms or signs of urinary tract infection (UTI) in 74 cases (38%; 95% confidence interval [CI], 31%–45%), nonspecific symptoms or signs in 83 cases (43%; 95% CI, 36%–50%), and no symptoms or signs of UTI in 38 cases (19%; 95% CI, 14%–25%). The median age was 51 (specific symptoms), 58 (nonspecific symptoms), and 61 (no symptoms), respectively (P = .005). Of 137 patients who produced the specimen without assistance, 78 (57%; 95% CI, 48%–65%) received no instructions on urine collection. Correct midstream clean-catch technique was used in 8 of 137 cases (6%). Presence of symptoms or signs was not associated with a new antibiotic prescription, but positive urinalysis (OR, 4.9; 95% CI, 1.7–14) and positive urine culture (OR, 3.6; 95% CI, 1.1–12) were. Of 36 patients receiving antibiotics, 10 (28%; 95% CI, 13%–43%) had no symptoms or nonspecific symptoms. Conclusion. In this sample at an urban teaching hospital ED, urine testing was not driven by symptoms. Improving practice may lower costs, improve efficiency of care, decrease unnecessary data that can distract providers and impair patient safety, decrease misdiagnosis, and decrease unnecessary antibiotics.

Abstract
US inpatient capacity increased until the 1970s, then declined. The US Census Bureau expects the population aged ≥65 years to more than double by 2050. The implications for national inpatient capacity requirements have not been quantified. Our objective was to calculate the number of hospital admissions that will be necessitated by population aging, ceteris paribus. We estimated 2011 nationwide age-specific hospitalization rates using data from the Nationwide Inpatient Sample and Census data. We applied these rates to the population expected by the Census Bureau to exist through 2050. By 2050, the US population is expected to increase by 41%. Our analysis suggests that based on expected changes in the population age structure by then, the annual number of hospitalizations will increase by 67%. Thus, inpatient capacity would have to expand 18% more than population growth to meet demand. Total aggregate inpatient days is projected to increase 22% more than population growth. The total projected growth in required inpatient capacity is 72%, accounting for both number of admissions and length of stay. This analysis accounts only for changes in the population's age structure. Other factors could increase or decrease demand, as discussed in the article.

A prospective pilot study of predictors of acute stroke in emergency department patients with dizziness. Mayo Clin Proc 2014; 89:173-80. [PMID: 24393411 PMCID: PMC3928680 DOI: 10.1016/j.mayocp.2013.10.026] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2013] [Revised: 09/17/2013] [Accepted: 10/02/2013] [Indexed: 10/25/2022]
Abstract
OBJECTIVE To prospectively examine undifferentiated emergency department (ED) patients with dizziness to identify clinical features associated with acute stroke. PATIENTS AND METHODS We conducted a pilot study from November 1, 2009, through October 30, 2010, of adult patients with dizziness presenting to 3 urban academic EDs. Data collected included demographic characteristics, medical history, presenting symptoms, examination findings, clinician pretest probability of stroke, and neuroimaging results. Logistic regression was used to identify variables with a significant association with acute stroke (P<.05). RESULTS During the study period, we enrolled 473 patients (mean ± SD age, 56.7±19.3 years; 60% female; and 71% white). We found 30 acute, serious diagnoses (6.3%), including 14 ischemic strokes, 2 subarachnoid hemorrhages, 7 mass lesions, 2 demyelinating lesions, 2 severe vertebral artery stenoses, 2 acute coronary syndromes, and 1 case of hydrocephalus and meningitis). We identified 6 clinical variables associated with stroke: age (odds ratio [OR], 1.04; 95% CI, 1.0-1.07), hyperlipidemia (OR, 3.62; 95% CI, 1.24-10.6), hypertension (OR, 4.91; 95% CI, 1.46-16.5), coronary artery disease (OR, 3.33; 95% CI, 1.06-10.5), abnormal tandem gait test result (OR, 3.13; 95% CI, 1.10-8.89), and high or moderate physician pretest probability for acute stroke (OR, 18.8; 95% CI, 4.72-74.5). CONCLUSIONS Most ED patients with dizziness do not have a serious cause of their symptoms. Although the small number of outcomes precluded development of a multivariate model, we identified several individual high-risk variables associated with acute ischemic stroke. Further study will be needed to validate the findings of this pilot investigation.

Skin infections and antibiotic stewardship: analysis of emergency department prescribing practices, 2007-2010. West J Emerg Med 2014; 15:282-9. [PMID: 24868305 PMCID: PMC4025524 DOI: 10.5811/westjem.2013.8.18040] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2013] [Accepted: 08/26/2013] [Indexed: 02/08/2023] Open
Abstract
Introduction: National guidelines suggest that most skin abscesses do not require antibiotics, and that cellulitis antibiotics should target streptococci, not community-associated MRSA (CA-MRSA). The objective of this study is to describe antimicrobial treatment of skin infections in U.S. emergency departments (EDs) and analyze potential quality measures. Methods: The National Hospital Ambulatory Medical Care Survey (NHAMCS) is a 4-stage probability sample of all non-federal U.S. ED visits. In 2007 NHAMCS started recording whether incision and drainage was performed at ED visits. We conducted a retrospective analysis, pooling 2007–2010 data, identified skin infections using diagnostic codes, and identified abscesses by performance of incision and drainage. We generated national estimates and 95% confidence intervals using weighted analyses; quantified frequencies and proportions; and evaluated antibiotic prescribing practices. We evaluated 4 parameters that might serve as quality measures of antibiotic stewardship, and present 2 of them as potentially robust enough for implementation. Results: Of all ED visits, 3.2% (95% confidence interval 3.1–3.4%) were for skin infection, and 2.7% (2.6–2.9%) were first visits for skin infection, with no increase over time (p=0.80). However, anti-CA-MRSA antibiotic use increased, from 61% (56–66%) to 74% (71–78%) of antibiotic regimens (p<0.001). Twenty-two percent of visits were for abscess, with a non-significant increase (p=0.06). Potential quality measures: Among discharged abscess patients, 87% were prescribed antibiotics (84–90%, overuse). Among antibiotic regimens for abscess patients, 84% included anti-CA-MRSA agents (81–89%, underuse). Conclusion: From 2007–2010, use of anti-CA-MRSA agents for skin infections increased significantly, despite stable visit frequencies. Antibiotics were over-used for discharged abscess cases, and CA-MRSA-active antibiotics were underused among regimens when antibiotics were used for abscess. [West J Emerg Med. 2014;15(3):282–289.]
