Feasibility of a Two-Step Palliative Screening Utilizing Existing Emergency Department Resources.

BACKGROUND: Although the Emergency Department (ED) offers a unique setting to provide early palliative care, staffing limitations curtail hospitals from establishing ED-palliative partnerships. MEASURES: Feasibility of a two-step ED-palliative screening protocol was defined by two criteria: a ≥ 50% increase in palliative consults originating from the ED and a ≥ 50% consultation completion rate for patients who screened positive for unmet palliative needs. INTERVENTION: A clinical decision support tool identified patients with treatment/code status limitations and prompted a care coordination referral. Care coordinators screened patients for unmet palliative needs using a content-validated screening tool and consulted palliative care for positive screens. OUTCOME: Palliative care consultations originating from the ED increased by 110% from 32 to 67 consultations, and 57% (40/70) of patients who screened positive for unmet palliative needs received a consultation. CONCLUSIONS/LESSONS LEARNED: Our project demonstrated feasibility of a two-step ED-palliative protocol by increasing palliative care consultation without necessitating additional staff.

Racial and Socioeconomic Disparities Evident in Inappropriate Antibiotic Prescribing in the Emergency Department.

STUDY OBJECTIVE: Inappropriate antibiotic prescribing for acute respiratory tract infections is a common source of low-value care in the emergency department (ED). Racial and socioeconomic disparities have been noted in episodes of low-value care, particularly in children. We evaluated whether prescribing rates for acute respiratory tract infections when antibiotics would be inappropriate by guidelines differed by race and socioeconomics. METHODS: A retrospective cross-sectional analysis of adult and pediatric patient encounters in the emergency department (ED) between 2015 and 2023 at 5 hospitals for acute respiratory tract infections that did not require antibiotics by guidelines. Multivariable regression was used to calculate the risk ratio between race, ethnicity, and area deprivation index and inappropriate antibiotic prescribing, controlling for patient age, sex, and relevant comorbidities. RESULTS: A total of 147,401 ED encounters (55% pediatric, 45% adult) were included. At arrival, 4% patients identified as Asian, 50% as Black, 5% as Hispanic, and 23% as White. Inappropriate prescribing was noted in 7.6% of overall encounters, 8% for Asian patients, 6% for Black patients, 5% for Hispanic patients, and 12% for White patients. After adjusting for age, sex, comorbidities, and area deprivation index, White patients had a 1.32 (95% confidence interval, 1.26 to 1.38) higher likelihood of receiving a prescription compared with Black patients. Patients residing in areas of greater socioeconomic deprivation, regardless of race and ethnicity, had a 0.74 (95% confidence interval, 0.70 to 0.78) lower likelihood of receiving a prescription. CONCLUSION: Our results suggest that although overall inappropriate prescribing was relatively low, White patients and patients from wealthier areas were more likely to receive an inappropriate antibiotic prescription.

Implementation Facilitation to Promote Emergency Department-Initiated Buprenorphine for Opioid Use Disorder.

Importance: Emergency department (ED)-initiated buprenorphine for the treatment of opioid use disorder (OUD) is underused. Objective: To evaluate whether provision of ED-initiated buprenorphine with referral for OUD increased after implementation facilitation (IF), an educational and implementation strategy. Design, Setting, and Participants: This multisite hybrid type 3 effectiveness-implementation nonrandomized trial compared grand rounds with IF, with pre-post 12-month baseline and IF evaluation periods, at 4 academic EDs. The study was conducted from April 1, 2017, to November 30, 2020. Participants were ED and community clinicians treating patients with OUD and observational cohorts of ED patients with untreated OUD. Data were analyzed from July 16, 2021, to July 14, 2022. Exposure: A 60-minute in-person grand rounds was compared with IF, a multicomponent facilitation strategy that engaged local champions, developed protocols, and provided learning collaboratives and performance feedback. Main Outcomes and Measures: The primary outcomes were the rate of patients in the observational cohorts who received ED-initiated buprenorphine with referral for OUD treatment (primary implementation outcome) and the rate of patients engaged in OUD treatment at 30 days after enrollment (effectiveness outcome). Additional implementation outcomes included the numbers of ED clinicians with an X-waiver to prescribe buprenorphine and ED visits with buprenorphine administered or prescribed and naloxone dispensed or prescribed. Results: A total of 394 patients were enrolled during the baseline evaluation period and 362 patients were enrolled during the IF evaluation period across all sites, for a total of 756 patients (540 [71.4%] male; mean [SD] age, 39.3 [11.7] years), with 223 Black patients (29.5%) and 394 White patients (52.1%). The cohort included 420 patients (55.6%) who were unemployed, and 431 patients (57.0%) reported unstable housing. Two patients (0.5%) received ED-initiated buprenorphine during the baseline period, compared with 53 patients (14.6%) during the IF evaluation period (P < .001). Forty patients (10.2%) were engaged with OUD treatment during the baseline period, compared with 59 patients (16.3%) during the IF evaluation period (P = .01). Patients in the IF evaluation period who received ED-initiated buprenorphine were more likely to be in treatment at 30 days (19 of 53 patients [35.8%]) than those who did not 40 of 309 patients (12.9%; P < .001). Additionally, there were increases in the numbers of ED clinicians with an X-waiver (from 11 to 196 clinicians) and ED visits with provision of buprenorphine (from 259 to 1256 visits) and naloxone (from 535 to 1091 visits). Conclusions and Relevance: In this multicenter effectiveness-implementation nonrandomized trial, rates of ED-initiated buprenorphine and engagement in OUD treatment were higher in the IF period, especially among patients who received ED-initiated buprenorphine.

Column adsorption of biological oxygen demand, chemical oxygen demand and total organic carbon from wastewater by magnetite nanoparticles-zeolite A composite.

Herein, magnetite nanoparticles (NPs), zeolite A and magnetite-zeolite A (MAGZA) composite was developed by green methods. The produced nanomaterials were characterized and the effect of process parameters such as flow rate, adsorbent bed height and adsorbate inlet concentration was evaluated for the removal of biological oxygen demand (BOD), chemical oxygen demand (COD) and total organic carbon (TOC) in a column. The characterization results demonstrated the successful synthesis of magnetite NPs, zeolite A and MAGZA composite. The performance of the MAGZA composite in the fixed-bed column was superior to zeolite A and magnetite NPs. The parametric influence indicates that an increase in bed height and a decrease in the flow rate and inlet adsorbate concentration improved the performance of the adsorption column. The adsorption column demonstrated maximum performance at a flow rate (4 mL/min), bed height (5 cm) and inlet adsorbate concentration (10 mg/L). Under these conditions, the highest percent removal of BOD, COD and TOC were 99.96, 99.88 and 99.87%. Thomas and Yoon-Nelson's model suitably fitted the breakthrough curves. After five reusability cycles, the MAGZA composite demonstrated removal percent of BOD (76.5%), COD (55.5%) and TOC (64.2%). The produced MAGZA composite effectively removed BOD, COD and TOC from textile wastewater in a continuous operating mode.

Evaluation of a pilot emergency department linkage to care program for patients previously diagnosed with Hepatitis C.

There is a significant number of Emergency Department (ED) patients with known chronic hepatitis C virus (HCV) infection who have not been treated with directly acting antivirals. We implemented a pilot ED-based linkage-to-care program to address this need and evaluated the impact of the program using the HCV Care Continuum metrics. Between March 2015 and May 2016, dedicated patient care navigators identified HCV RNA-positive patients in an urban ED and offered expedited appointments with the on-site viral hepatitis clinic. Patient demographics and care continuum outcomes were abstracted from the EMR and analysed to determine significant factors influencing linkage-to-care (LTC) and treatment initiation rates. The ED linkage-to-care program achieved a 43% linkage-to-care rate (165/384), 22% treatment rate (84/384) and 16% sustained virologic response rate (63/384). Significant associations were found between linkage-to-care and increasing age (OR = 1.03), Medicare insurance (OR = 2.21) and having a primary care physician (PCP) (OR = 4.03). For patients who were linked, the odds of initiating treatment were also positively significantly associated with increasing age (OR = 1.04) and having a PCP (OR = 2.77). For patients who initiated treatment, the odds of sustained virologic response were marginally associated with having a PCP (OR = 4.92).Our ED linkage-to-care program utilized care coordination to successfully link nearly half of approached HCV RNA-positive patients to care. This design can be feasibly replicated by other EDs given limited non-clinical training required for linkage-to-care staff. Adoption of similar programs in other EDs may improve the rates of LTC and treatment initiation for previously diagnosed HCV patients.

Prospective, multi-site study of patient outcomes after implementation of the TREWS machine learning-based early warning system for sepsis.

Early recognition and treatment of sepsis are linked to improved patient outcomes. Machine learning-based early warning systems may reduce the time to recognition, but few systems have undergone clinical evaluation. In this prospective, multi-site cohort study, we examined the association between patient outcomes and provider interaction with a deployed sepsis alert system called the Targeted Real-time Early Warning System (TREWS). During the study, 590,736 patients were monitored by TREWS across five hospitals. We focused our analysis on 6,877 patients with sepsis who were identified by the alert before initiation of antibiotic therapy. Adjusting for patient presentation and severity, patients in this group whose alert was confirmed by a provider within 3 h of the alert had a reduced in-hospital mortality rate (3.3%, confidence interval (CI) 1.7, 5.1%, adjusted absolute reduction, and 18.7%, CI 9.4, 27.0%, adjusted relative reduction), organ failure and length of stay compared with patients whose alert was not confirmed by a provider within 3 h. Improvements in mortality rate (4.5%, CI 0.8, 8.3%, adjusted absolute reduction) and organ failure were larger among those patients who were additionally flagged as high risk. Our findings indicate that early warning systems have the potential to identify sepsis patients early and improve patient outcomes and that sepsis patients who would benefit the most from early treatment can be identified and prioritized at the time of the alert.

Factors driving provider adoption of the TREWS machine learning-based early warning system and its effects on sepsis treatment timing.

Machine learning-based clinical decision support tools for sepsis create opportunities to identify at-risk patients and initiate treatments at early time points, which is critical for improving sepsis outcomes. In view of the increasing use of such systems, better understanding of how they are adopted and used by healthcare providers is needed. Here, we analyzed provider interactions with a sepsis early detection tool (Targeted Real-time Early Warning System), which was deployed at five hospitals over a 2-year period. Among 9,805 retrospectively identified sepsis cases, the early detection tool achieved high sensitivity (82% of sepsis cases were identified) and a high rate of adoption: 89% of all alerts by the system were evaluated by a physician or advanced practice provider and 38% of evaluated alerts were confirmed by a provider. Adjusting for patient presentation and severity, patients with sepsis whose alert was confirmed by a provider within 3 h had a 1.85-h (95% CI 1.66-2.00) reduction in median time to first antibiotic order compared to patients with sepsis whose alert was either dismissed, confirmed more than 3 h after the alert or never addressed in the system. Finally, we found that emergency department providers and providers who had previous interactions with an alert were more likely to interact with alerts, as well as to confirm alerts on retrospectively identified patients with sepsis. Beyond efforts to improve the performance of early warning systems, efforts to improve adoption are essential to their clinical impact and should focus on understanding providers' knowledge of, experience with and attitudes toward such systems.

Models for Implementing Emergency Department-Initiated Buprenorphine With Referral for Ongoing Medication Treatment at Emergency Department Discharge in Diverse Academic Centers.

There has been a substantial rise in the number of publications and training opportunities on the care and treatment of emergency department (ED) patients with opioid use disorder over the past several years. The American College of Emergency Physicians recently published recommendations for providing buprenorphine to patients with opioid use disorder, but barriers to implementing this clinical practice remain. We describe the models for implementing ED-initiated buprenorphine at 4 diverse urban, academic medical centers across the country as part of a federally funded effort termed "Project ED Health." These 4 sites successfully implemented unique ED-initiated buprenorphine programs as part of a comparison of implementation facilitation to traditional educational dissemination on the uptake of ED-initiated buprenorphine. Each site describes the elements central to the ED process, including screening, treatment initiation, referral, and follow-up, while harnessing organizational characteristics, including ED culture. Finally, we discuss common facilitators to program success, including information technology and electronic medical record integration, hospital-level support, strong connections with outpatient partners, and quality improvement processes.

Comparison of HIV Screening Strategies in the Emergency Department: A Randomized Clinical Trial.

Importance: The National HIV Strategic Plan for the US recommends HIV screening in emergency departments (EDs). The most effective approach to ED-based HIV screening remains unknown. Objective: To compare strategies for HIV screening when integrated into usual ED practice. Design, Setting, and Participants: This randomized clinical trial included patients visiting EDs at 4 US urban hospitals between April 2014 and January 2016. Patients included were ages 16 years or older, not critically ill or mentally altered, not known to have an HIV positive status, and with an anticipated length of stay 30 minutes or longer. Data were analyzed through March 2021. Interventions: Consecutive patients underwent concealed randomization to either nontargeted screening, enhanced targeted screening using a quantitative HIV risk prediction tool, or traditional targeted screening as adapted from the Centers for Disease Control and Prevention. Screening was integrated into clinical practice using opt-out consent and fourth-generation antigen-antibody assays. Main Outcomes and Measures: New HIV diagnoses using intention-to-treat analysis, absolute differences, and risk ratios (RRs). Results: A total of 76 561 patient visits were randomized; median (interquartile range) age was 40 (28-54) years, 34 807 patients (51.2%) were women, and 26 776 (39.4%) were Black, 22 131 (32.6%) non-Hispanic White, and 14 542 (21.4%) Hispanic. A total of 25 469 were randomized to nontargeted screening; 25 453, enhanced targeted screening; and 25 639, traditional targeted screening. Of the nontargeted group, 6744 participants (26.5%) completed testing and 10 (0.15%) were newly diagnosed; of the enhanced targeted group, 13 883 participants (54.5%) met risk criteria, 4488 (32.3%) completed testing, and 7 (0.16%) were newly diagnosed; and of the traditional targeted group, 7099 participants (27.7%) met risk criteria, 3173 (44.7%) completed testing, and 7 (0.22%) were newly diagnosed. When compared with nontargeted screening, targeted strategies were not associated with a higher rate of new diagnoses (enhanced targeted and traditional targeted combined: difference, -0.01%; 95% CI, -0.04% to 0.02%; RR, 0.7; 95% CI, 0.30 to 1.56; P = .38; and enhanced targeted only: difference, -0.01%; 95% CI, -0.04% to 0.02%; RR, 0.70; 95% CI, 0.27 to 1.84; P = .47). Conclusions and Relevance: Targeted HIV screening was not superior to nontargeted HIV screening in the ED. Nontargeted screening resulted in significantly more tests performed, although all strategies identified relatively low numbers of new HIV diagnoses.

Treatment of Acute Pain in Adults With Sickle Cell Disease in an Infusion Center Versus the Emergency Department : A Multicenter Prospective Cohort Study.

BACKGROUND: Patients with sickle cell disease (SCD) have vaso-occlusive crises (VOCs). Infusion centers (ICs) are alternatives to emergency department (ED) care and may improve patient outcomes. OBJECTIVE: To assess whether care in ICs or EDs leads to better outcomes for the treatment of uncomplicated VOCs. DESIGN: Prospective cohort. (ClinicalTrials.gov: NCT02411396). SETTING: 4 U.S. sites, with recruitment between April 2015 and December 2016. PARTICIPANTS: Adults with SCD living within 60 miles of a study site. MEASUREMENTS: Participants were followed for 18 months after enrollment. Outcomes of interest were time to first dose of parenteral pain medication, whether pain reassessment was completed within 30 minutes after the first dose, and patient disposition on discharge from the acute care visit. Treatment effects for ICs versus EDs were estimated using a time-varying propensity score adjustment. RESULTS: Researchers enrolled 483 participants; the 269 who had acute care visits on weekdays are included in this report. With inverse probability of treatment-weighted adjustment, the mean time to first dose was 62 minutes in ICs and 132 minutes in EDs; the difference was 70 minutes (95% CI, 54 to 98 minutes; E-value, 2.8). The probability of pain reassessment within 30 minutes of the first dose of parenteral pain medication was 3.8 times greater (CI, 2.63 to 5.64 times greater; E-value, 4.7) in the IC than the ED. The probability that a participant's visit would end in admission to the hospital was smaller by a factor of 4 (0.25 [CI, 0.18 to 0.33]) with treatment in an IC versus an ED. LIMITATION: The study was restricted to participants with uncomplicated VOCs. CONCLUSION: In adults with SCD having a VOC, treatment in an IC is associated with substantially better outcomes than treatment in an ED.

Characterization and impact of COVID-19-tested and infected patients: Experience of The Johns Hopkins Health System Regional Emergency Departments.

BACKGROUND: There is limited understanding of the characteristics and operational burden of persons under investigation (PUIs) and those testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) presenting to emergency departments (EDs). METHODS: We reviewed all adult ED visits to 5 Johns Hopkins Health System hospitals in the Maryland/District of Columbia (DC) region during the initial coronavirus disease 2019 (COVID-19) surge, analyzing SARS-CoV-2 polymerase chain reaction test eligibility, results, demographics, acuity, clinical conditions, and dispositions. RESULTS: Of 27,335 visits, 11,402 (41.7%) were tested and 2484 (21.8%) were SARS-CoV-2 positive. Test-positive rates among Hispanics, Asians, African Americans/Blacks, and Whites were 51.6%, 23.7%, 19.8%, and 12.7% respectively. African American/Blacks infection rates (25.5%-33.8%) were approximately double those of Whites (11.1%-21.1%) in the 3 southern Maryland/DC EDs. Conditions with high test-positive rates were fever (41.9%), constitutional (36.4%), upper respiratory (36.9%), and lower respiratory (31.2%) symptoms. Test-positive rates were similar in all age groups (19.9% to 25.8%), although rates of hospitalization increased successively with age. Almost half, 1103 (44.4%), of test-positive patients required admission, of which 206 (18.7%) were to an ICU. CONCLUSION: The initial surge of SARS-CoV-2 test-positive patients experienced in a regional hospital system had ≈ 42% of patients meeting testing criteria and nearly one-fifth of those testing positive. The operational burden on ED practice, including intense adherence to infection control precautions, cannot be understated. Disproportionately high rates of infection among underrepresented minorities underscores the vulnerability in this population. The high rate of infection among self-identified Asians was unexpected.

Emergency Department-Based Human Immunodeficiency Virus Preexposure Prophylaxis Referral Program-Using Emergency Departments as a Portal for Preexposure Prophylaxis Services.

ABSTRACT: A pilot program was implemented to assess the feasibility of emergency department (ED) preexposure prophylaxis (PrEP) referral. Of 119 eligible patients approached and assessed, 39 (33%) expressed interest and were referred to peer navigators. Of these, 16 (41%) scheduled for appointments; four (10%) initiated PrEP, which demonstrated ED-based PrEP referral was feasible.

Reduction in Emergency Department Presentations in a Regional Health System during the Covid-19 Pandemic.

INTRODUCTION: Nationally, there has been more than a 40% decrease in Emergency Department (ED) patient volume during the coronavirus disease 2019 (Covid-19) crisis, with reports of decreases in presentations of time-sensitive acute illnesses. We analyzed ED clinical presentations in a Maryland/District of Columbia regional hospital system while health mitigation measures were instituted. METHODS: We conducted a retrospective observational cohort study of all adult ED patients presenting to five Johns Hopkins Health System (JHHS) hospitals comparing visits from March 16 through May 15, in 2019 and 2020. We analyzed de-identified demographic information, clinical conditions, and ICD-10 diagnosis codes for year-over-year comparisons. RESULTS: There were 36.7% fewer JHHS ED visits in 2020 compared to 2019 (43,088 vs. 27,293, P<.001). Patients 75+ had the greatest decline in visits (-44.00%, P<.001). Both genders had significant decreases in volume (-41.9%, P<.001 females vs -30.6%, P<.001 males). Influenza like illness (ILI) symptoms increased year-over-year including fever (640 to 1253, 95.8%, P<.001) and shortness of breath (2504 to 2726, 8.9%, P=.002). ICD-10 diagnoses for a number of time-sensitive illnesses decreased including deep vein thrombosis (101 to 39, -61%, P<.001), acute myocardial infarction (157 to 105, -33%, P=.002), gastrointestinal bleeding (290 to 179, -38.3%, P<.001), and strokes (284 to 234, -17.6%, P=0.03). CONCLUSION: ED visits declined significantly among JHHS hospitals despite offsetting increases in ILI complaints. Decreases in presentations of time-sensitive illnesses were of particular concern. Efforts should be taken to inform patients that EDs are safe, otherwise preventable morbidity and mortality will remain a problem.

Improving antimicrobial prescribing for upper respiratory infections in the emergency department: Implementation of peer comparison with behavioral feedback.

Objective: To reduce inappropriate antibiotic prescribing for acute respiratory infections (ARIs) by employing peer comparison with behavioral feedback in the emergency department (ED). Design: A controlled before-and-after study. Setting: The study was conducted in 5 adult EDs at teaching and community hospitals in a health system. Patients: Adults presenting to the ED with a respiratory condition diagnosis code. Hospitalized patients and those with a diagnosis code for a non-respiratory condition for which antibiotics are or may be warranted were excluded. Interventions: After a baseline period from January 2016 to March 2018, 3 EDs implemented a feedback intervention with peer comparison between April 2018 and December 2019 for attending physicians. Also, 2 EDs in the health system served as controls. Using interrupted time series analysis, the inappropriate ARI prescribing rate was calculated as the proportion of antibiotic-inappropriate ARI encounters with a prescription. Prescribing rates were also evaluated for all ARIs. Attending physicians at intervention sites received biannual e-mails with their inappropriate prescribing rate and had access to a dashboard that was updated daily showing their performance relative to their peers. Results: Among 28,544 ARI encounters, the inappropriate prescribing rate remained stable at the control EDs between the 2 periods (23.0% and 23.8%). At the intervention sites, the inappropriate prescribing rate decreased significantly from 22.0% to 15.2%. Between periods, the overall ARI prescribing rate was 38.1% and 40.6% in the control group and 35.9% and 30.6% in the intervention group. Conclusions: Behavioral feedback with peer comparison can be implemented effectively in the ED to reduce inappropriate prescribing for ARIs.

Emergency Department Ergonomic Redesign Improves Team Satisfaction in Cardiopulmonary Resuscitation Delivery: A Simulation-Based Quality Improvement Approach.

BACKGROUND: Delivering high-quality cardiopulmonary resuscitation (CPR) requires teams to administer highly choreographed care. The American Heart Association recommends audiovisual feedback for real-time optimization of CPR performance. In our Emergency Department (ED) resuscitation bays, ZOLL cardiac resuscitation device visibility was limited. OBJECTIVE: To optimize the physical layout of our resuscitation rooms to improve cardiac resuscitation device visibility for real-time CPR feedback. METHODS: A simulated case of cardiac arrest with iterative ergonomic modifications was performed four times. Variables included the locations of the cardiac resuscitation device and of team members. Participants completed individual surveys and provided qualitative comments in a group debriefing. The primary outcome of interest was participants' perception of cardiac resuscitation device visibility. RESULTS: The highest scoring layout placed the cardiac resuscitation device directly across from the compressor and mirrored the device screen to a television mounted at the head of the bed. Comparing this configuration to our standard configuration on a five-point Likert scale, cardiac resuscitation device visibility increased 46.7% for all team members, 150% for the team leader, and 179% for team members performing chest compressions. CONCLUSION: An iterative, multidisciplinary, simulation-based approach can improve team satisfaction with important clinical care factors when caring for patients suffering cardiac arrest in the ED.

Safety Trial of Low-Intensity Monitoring After Thrombolysis: Optimal Post Tpa-Iv Monitoring in Ischemic STroke (OPTIMIST).

BACKGROUND AND PURPOSE: At present, stroke patients receiving intravenous thrombolysis (IVT) undergo monitoring of their neurological status and vital signs every 15 minutes for the first 2 hours, every 30 minutes for the next 6 hours, and every hour thereafter up to 24 hours post-IVT. The present study sought to prospectively evaluate whether post-IVT stroke patients with low risk for complications may safely be cared for utilizing a novel low-intensity monitoring protocol. METHODS: In this pragmatic, prospective, single-center, open-label, single-arm safety study, we enrolled 35 post-IVT stroke patients. Adult patients were eligible if their NIH Stroke Scale (NIHSS) was less than 10 at the time of presentation, and if they had no critical care needs by the end of the IVT infusion. Patients underwent a low-intensity monitoring protocol during the first 24 hours after IVT. The primary outcome was need for a critical care intervention in the first 24 hours after IVT. RESULTS: The median age was 54 years (range: 32-79), and the median pre-IVT NIHSS was 3 (interquartile range [IQR]: 1-6). None of the 35 patients required transfer to the intensive care unit or a critical care intervention in the first 24 hours after IVT. The median NIHSS at 24 hours after IVT was 1 (IQR: 0-3). Four (11.4%) patients were stroke mimics, and the vast majority was discharged to home (82.9%). At 90 days, the median NIHSS was 0 (IQR: 0-1), and the median modified Rankin Scale was 0 (range: 0-6). CONCLUSION: Post-IVT stroke patients may be safely monitored in the setting of a low-intensity protocol.

A randomized controlled trial of online symptom searching to inform patient generated differential diagnoses.

Patient online health searching is now commonplace, however, the accuracy of patient generated differentials for new symptoms and potential for patient anxiety are concerns. We aimed primarily to determine the accuracy of patient generated differentials for new symptoms with and without online searching, and secondarily, to evaluate the impact of searching on anxiety levels. In the waiting room prior to seeing a clinician, 300 patients with new symptoms were randomly assigned 1:1:1 to Google searching with health related features including a symptom search tool vs Google searching with health related features disabled vs no searching. Participants were 18 years or older and presenting to the emergency department of an urban academic medical center with new low-acuity symptoms that were not due to exacerbation of a chronic condition. Search groups received access on a tablet/smartphone to Google searching with or without health related features. Both search groups could access any websites; health related features led the patient to common diagnoses and physician-validated information. The primary outcome was accuracy of the patient generated differential assessed by matching at least two of the top three diagnoses on the clinician's differential. A secondary outcome was anxiety by a visual analogue scale. Patients were a median of 33.1 (IQI 26.2-45.9) years old, 60% women, 63% black, 82% had a high school education or less, and 45.7% reported having performed an online search prior to presentation. Search group patients spent a median of 3.82 (2.53-5.72) minutes searching online. Similar proportions of patients in each group matched at least two of three clinician diagnoses: 27.0% and 28.3% for Google searching with and without health related features vs 23.8% in the no search group. Patients in the search groups had a similar odds of matching ≥2/3 diagnoses as the no search group [OR (95% CI): 1.23 (0.70-2.13), p = 0.47]. Anxiety was unchanged with online searching. In conclusion, brief online searching in the waiting room did not improve accuracy of patient generated differential diagnoses for new symptoms. The absence of an increase in patient anxiety provides reassurance for subsequent work to refine and investigate online symptom search tools.

Advanced liver fibrosis and care continuum in emergency department patients with chronic hepatitis C.

BACKGROUND: FIB-4, a non-invasive serum fibrosis index (which includes age, ALT, AST, and platelet count), is frequently available during ED visits. Our objective was to define 1-year HCV-related care outcomes of ED patients with known HCV, for the overall group, and both those with and without advanced fibrosis. METHODS: As part of an ongoing HCV linkage-to-care (LTC) program, HCV-infected ED patients were identified retrospectively via medical record review. Components of FIB-4 were abstracted, and patients with an FIB-4 > 3.25 were classified with advanced fibrosis and characterized with regards to downstream HCV care continuum outcomes at one-year after enrollment. RESULTS: Of the 113 patients with known HCV, 38 (33.6%) had advanced fibrosis. One-year outcomes along the HCV care continuum after ED encounter for 'all' 113, 75 'without advanced fibrosis', and 38 'advanced fibrosis' patients, respectively, were as follows: agreeing to be linked to care [106 (93.8%), 72 (96.0%), 34 (89.5%)]; LTC [38 (33.6%), 21 (28.0%), 17 (44.7%)]; treatment initiation among those linked [16 (42.1%), 9 (42.9%), 7 (41.2%)]; sustained virologic response 4 weeks post-treatment among those treated [15 (93.8%), 9 (100.0%), 6 (85.7%)]; documented all-cause mortality [10 (8.8%), 3 (4.0%), 7 (18.4%)]. Notably, 70% of those who died had advanced fibrosis. For those with advanced liver fibrosis, all-cause mortality was significantly higher, than those without (18.4% versus 4.0%, p = 0.030). CONCLUSIONS: Over one-third of HCV-infected ED patients have advanced liver fibrosis, incomplete LTC, and higher mortality, suggesting this readily-available FIB-4 might be used to prioritize LTC services for those with advanced fibrosis.
