General Surgery Residents Improve Efficiency but Not Hospital Length of Stay in Trauma Care.

Background Good Samaritan University Hospital (GSUH) has been preliminary approved to become a Level I Trauma Center. The American College of Surgeons (ACS) requires Level I Trauma Centers to have senior surgery residents on the trauma service. To fulfill this requirement, GSUH has established an affiliation with Stony Brook University Hospital, a tertiary care hospital with an Accreditation Council for Graduate Medical Education-approved five-year postgraduate training program in General Surgery, to have senior surgery residents from their training program rotate and provide care to trauma patients beginning in July of 2021. Numerous studies over the past few decades have shown conflicting results on patient outcomes with resident involvement. A majority of the studies published only evaluated residents who were native to the respective hospitals. Our study evaluated the impact of surgery residents visiting from an outside hospital on hospital length of stay (LOS) in admitted trauma patients. As increased hospital LOS is strongly associated with increased hospital-acquired complications, increased healthcare costs, and poor patient experience, we used this to evaluate the efficiency of our trauma team with the addition of visiting surgery residents. Methodology A retrospective study was conducted utilizing the hospital's trauma registry. Patients were divided into two groups: the first two years before the addition of surgery residents from July 1st, 2019, to June 30th, 2021, and the second two years after the addition of surgery residents from July 1st, 2021, to June 30th, 2023. The primary outcome measured the hospital LOS between the two groups. Pearson's chi-square test was used to analyze all categorical data, and a t-test was used to compare differences in means. Results From July 1st, 2019, to June 30th, 2023, a total of 7,081 patients were admitted to the trauma service: 3,411 in the group with no surgery residents, and 3,670 patients in the group with residents (p = 0.052). The primary outcome, hospital LOS, was not significantly affected by the addition of surgery residents to the trauma service. Hospital LOS before surgery residents was 4.40 days compared to with residents at 4.41 days (p = 0.944). Mortality was significantly decreased with resident involvement at 1.9% compared to no residents at 2.7% (p = 0.017). Interestingly, the Emergency Department LOS was significantly longer in the group with residents, 268.82 minutes vs. 232.19 minutes (p = 0.004). The average New Injury Severity Score was 9.02 in the group with no residents and 9.04 in the group with surgery residents (p = 0.927). The majority of traumas in both groups were blunt trauma 96.5% with no residents vs. 97.1% with residents (p = 0.192). Conclusions The addition of visiting surgery residents to the trauma team did not significantly increase hospital LOS. Ultimately, having visiting residents on the trauma service may enhance resident education without compromising hospital LOS. Training at different hospitals can allow residents to experience different patient populations and different hospital protocols, making them adaptable and more prepared to work in different hospital settings, whether academic or community. Hospitals without their own residency programs could potentially form affiliations with residency programs to meet the ACS requirements, which can bring more patients to their hospitals.

Resource Deployment in Response to Trauma Patients.

Background Variance in the deployment of the trauma team to the emergency department (ED) can result in patient treatment delays and excess burden on ED personnel. Characteristics of trauma patients, including mechanism of injury, injury type, and age, have been associated with differences in trauma resource deployment. Therefore, this retrospective, single-site study aimed to examine the deployment patterns of trauma resources, the characteristics of the trauma patients associated with levels of trauma resource deployment, and the deployment impact on ED workforce utilization and non-trauma ED patients. Methodology This was an investigator-initiated, single-institution, retrospective cohort study of all patients designated as a trauma response and admitted to a community hospital's ED from July 01, 2019, through July 01, 2022. Results Resource deployment for trauma patients varied by mechanism of injury (p < 0.001), injury type (p < 0.001), and patient age groups (p < 0.001). Specifically, there was a lower average trauma activation for geriatric trauma patients with a fall as a mechanism of injury compared to all younger patient groups with any mechanism of injury (F(5) = 234.49, p < 0.001). In the subsample, there was an average of 3.35 ED registered nurses (RNs) allocated to each trauma patient. Additionally, the ED RNs were temporarily reallocated from an average of 4.09 non-trauma patients to respond to trauma patients, despite over a third of the trauma patients in the subsample being the trauma patients being discharged home from the ED. Conclusions Trauma activation responses need to be standardized with a specific plan for geriatric fall patients to ensure efficient use of trauma and ED personnel resources.

Measuring Emergency Department Staff Perceptions of Causes and Management of Violence.

BACKGROUND: Half of all reported violent incidents in health care settings occur in the emergency department (ED) placing all staff members at risk. However, research typically does not include all ED work groups or validated measures beyond nurses and physicians. OBJECTIVE: The aims of this study were to (a) validate an established instrument measuring perceptions of causes of violence and attitudes toward managing violence within an inclusive workforce sample; and (b) explore variation in perceptions, attitudes, and incidence of violence and safety to inform a violence prevention program. METHODS: This is an investigator-initiated single-site cross-sectional survey design assessing the psychometric properties of the Management of Aggression and Violence Attitude Scale (MAVAS) within a convenience sample (n = 134). Construct validity was assessed using exploratory factor analysis and reliability was evaluated by the Cronbach's α estimation. Descriptive, correlational, and inferential estimates explored differences in perceptions, attitudes, and incidence of violence and safety. RESULTS: Exploratory factor analysis indicated validity of the MAVAS with a seven-factor model. Its internal consistency was satisfactory overall (Cronbach's α= 0.87) and across all subscales (Cronbach's α values = 0.52-0.80). Significant variation in incidence of physical assault, perceptions of safety, and causes of violence was found between work groups. CONCLUSIONS: The MAVAS is a valid and reliable tool to measure ED staff members' perceptions of causes of violence and attitudes toward managing violence. In addition, it can inform training according to differences in work group learner needs.

Peer recovery coaches and emergency department utilization in patients with substance use disorders.

BACKGROUND: Although Emergency Departments (ED) frequently provide care for patients with substance use disorders (SUD), there are many barriers to connecting them with appropriate long-term treatment. One approach to subside risk in this population is the Peer Recovery Coach (PRC). PRCs are individuals with a lived experience of the rehabilitation process and are a powerful resource to bridge this gap in care by engaging patients and their families and providing system navigation, self-empowerment for behavior change, and harm reduction strategies. The purpose of this project is to describe an ED-based PRC program, evaluating its feasibility and efficacy. METHODS: This was a retrospective quality improvement project conducted at 3 suburban hospitals. All patients arriving to the ED were screened with a brief questionnaire in triage and patients identified as a high-risk had referral placed to a PRC if the patient consented. The PRC met with the patient at the ED bedside if possible. The PRC program members collected prospective data on patient engagement with the PRC at 30, 60, and 90 days post ED encounter. Using the EMR we identified the number of subsequent ED visits at 30, 60, and 90 days (for both medical and substance use disorder-related visits) from the index PRC visit. RESULTS: There were 448 individuals identified and included in this analysis between January 1, 2019 and June 30, 2020, of which 292 (66%) were male and the mean age was 44 (range 18-80). Most patients identified alcohol as the primary substance they used (289, 65%), followed by heroin/opiates (20%). At 30, 60, and 90 days, there were 110 (25%), 79 (18%), and 71 (16%) patients who were still actively engaged in the program, respectively. Among all patients in the cohort, there was essentially no decrease in mean visits before versus after the PRC engagement visit. However, among patients who had at least one prior ED visit, there were significant differences in mean visits across all visit-types: for patients with 1 prior ED visit, 90 day mean decrease in visits = 1.0 visits (95% CI 0.7-1.2), for patients with 5+ prior ED visits, 90 day mean decrease in visits = 3.6 visits (95% CI 2.4-4.8). CONCLUSION: We describe the implementation of an ED-based PRC program for patients with substance use disorders. While we demonstrated that it is feasible for the PRC to engage the patient while in the ED, there was poor follow-up with the program outpatient. For patients with at least one previous SUD visit to the ED, there was a statistically significant reduction in ED utilization after engaging with a PRC while in the ED, suggesting this may be a population that could be targeted to link patients to long term care and decrease repeated ED utilization.

Posterior Globe Depth for Optic Nerve Sheath Diameter Measurement in Ocular Ultrasound in Healthy Volunteers.

BACKGROUND: Point-of-care ultrasound (POCUS) is a readily available imaging modality in many emergency departments and health care facilities globally. Optic nerve sheath diameter (ONSD) measurement via ocular ultrasound has been shown to accurately predict increased intracranial pressure. Classically, the preferred technique for sonographic measurement of ONSD has specified measurement at an optimal position of 3 mm posterior to the globe. This study aims to validate an alternative approach of depth measurement (between 3 and 8 mm), with the hypothesis that ONSD should not change in size as the distance posterior to the globe increases. METHODS: Healthy volunteers aged > 18 years were studied. A point 3 mm posterior to the optic disc was located. This was repeated at a point 5 mm as well as 8 mm posterior to the globe. RESULTS: We enrolled 10 healthy participants. When evaluating variability in ONSD measurements at each of the three distances, we found that the difference in the measurements at each distance was statistically significant. In investigating pairwise comparisons, there was no difference between 3 and 5 mm, but there were differences in ONSD measurements at 3 and 8 mm, as well as at 5 and 8 mm. CONCLUSION: POCUS is readily available in many emergency departments and health care facilities across the world. The classically preferred technique for sonographic measurement of ONSD has specified measurement at an optimal position of 3 mm posterior to the globe. Our results identified that ONSD can be measured between 3 and 5 mm with no significant changes.

Comparison of outcomes between pulseless electrical activity by electrocardiography and pulseless myocardial activity by echocardiography in out-of-hospital cardiac arrest; secondary analysis from a large, prospective study.

OBJECTIVE: To measure prevalence of discordance between electrical activity recorded by electrocardiography (ECG) and myocardial activity visualized by echocardiography (echo) in patients presenting after cardiac arrest and to compare survival outcomes in cohorts defined by ECG and echo. METHODS: This is a secondary analysis of a previously published prospective study at twenty hospitals. Patients presenting after out-of-hospital arrest were included. The cardiac electrical activity was defined by ECG and contemporaneous myocardial activity was defined by bedside echo. Myocardial activity by echo was classified as myocardial asystole--the absence of myocardial movement, pulseless myocardial activity (PMA)--visible myocardial movement but no pulse, and myocardial fibrillation--visualized fibrillation. Primary outcome was the prevalence of discordance between electrical activity and myocardial activity. RESULTS: 793 patients and 1943 pauses in CPR were included. 28.6% of CPR pauses demonstrated a difference in electrical activity (ECG) and myocardial activity (echo), 5.0% with asystole (ECG) and PMA (echo), and 22.1% with PEA (ECG) and myocardial asystole (echo). Twenty-five percent of the 32 pauses in CPR with a shockable rhythm by echo demonstrated a non-shockable rhythm by ECG and were not defibrillated. Survival for patients with PMA (echo) was 29.1% (95%CI-23.9-34.9) compared to those with PEA (ECG) (21.4%, 95%CI-17.7-25.6). CONCLUSION: Patients in cardiac arrest commonly demonstrate different electrical (ECG) and myocardial activity (echo). Further research is needed to better define cardiac activity during cardiac arrest and to explore outcome between groups defined by electrical and myocardial activity.

Credentialing Pediatric Emergency Medicine Faculty in Point-of-Care Ultrasound: Expert Guidelines.

ABSTRACT: As point-of-care ultrasound (POCUS) becomes standard practice in pediatric emergency medicine (PEM), it is important to have benchmarks in place for credentialing PEM faculty in POCUS. Faculty must be systematically trained and assessed for competency in order to be credentialed in POCUS and granted privileges by an individual institution. Recommendations on credentialing PEM faculty are needed to ensure appropriate, consistent, and responsible use of this diagnostic and procedural tool. It is our intention that these guidelines will serve as a framework for credentialing faculty in PEM POCUS.

Emergency department sepsis huddles: Achieving excellence for sepsis benchmarks in New York State.

The sepsis order set at our institution was created with the intent to facilitate the prompt initiation of appropriate sepsis care. Once clinical features meeting criteria for systemic inflammatory response syndrome (SIRS) are identified and an infectious source is considered, a "sepsis huddle" is concomitantly initiated. The sepsis huddle was implemented in March of 2016 in order to increase compliance with the sepsis bundles. The sepsis huddle is called via overhead paging system in the emergency department (ED) to notify all staff that there is a patient present who meets SIRS criteria with concern for sepsis requiring immediate attention. The sepsis order set is utilized for these patients and includes laboratory testing, treatment, and monitoring items to meet sepsis "bundle" compliance. In addition, it suggests antibiotic options to be administered based on the presumed source of infection. Each team member responding to a sepsis huddle has a pre-established role outlined to facilitate timely treatment. The Centers for Medicare & Medicaid Services, (CMS), is part of the Department of Health and Human Services (HHS). CMS sepsis guidelines call for periodic patient reassessment, including repeat vital signs, pertinent physical examination findings, and timed lactic acid measurement to determine a patient's response to resuscitation efforts. Our established order set has automated some of these reassessment features to facilitate compliance. Sepsis huddle initiation also triggers a department staff member to track the timing and completion of serial blood draws. Utilizing and adhering to the guidelines of this methodology in the management of these patients has enabled our hospital to improve benchmarking compliance from previously underperforming at the 31st and 49th percentiles in 2015, prior to initiation of the huddle, to a peak compliance at the 81st and 91st percentiles in 2016 and 65th and 83rd percentiles in 2017 for the 3-hour and 6-hour bundles respectively.

The diagnostic accuracy of a point-of-care ultrasound protocol for shock etiology: A systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to perform a systematic review and meta-analysis of the diagnostic accuracy of a point-of-care ultrasound exam for undifferentiated shock in patients presenting to the emergency department. METHODS: Ovid MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, and research meeting abstracts were searched from 1966 to June 2018 for relevant studies. QUADAS-2 was used to assess study quality, and meta-analysis was conducted to pool performance data of individual categories of shock. RESULTS: A total of 5,097 non-duplicated studies were identified, of which 58 underwent full-text review; 4 were included for analysis. Study quality by QUADAS-2 was considered overall a low risk of bias. Pooled positive likelihood ratio values ranged from 8.25 (95% CI 3.29 to 20.69) for hypovolemic shock to 40.54 (95% CI 12.06 to 136.28) for obstructive shock. Pooled negative likelihood ratio values ranged from 0.13 (95% CI 0.04 to 0.48) for obstructive shock to 0.32 (95% CI 0.16 to 0.62) for mixed-etiology shock. CONCLUSION: The rapid ultrasound for shock and hypotension (RUSH) exam performs better when used to rule in causes of shock, rather than to definitively exclude specific etiologies. The negative likelihood ratios of the exam by subtype suggest that it most accurately rules out obstructive shock.

Comparative efficiency of exercise stress testing with and without stress-only myocardial perfusion imaging in patients with low-risk chest pain.

OBJECTIVES: To compare major adverse cardiac event (MACE), downstream resource utilization, and direct cost of care for low-risk chest pain patients observed in the clinical decision unit (CDU) with exercise treadmill testing (ETT) and with stress-only myocardial perfusion imaging (sMPI). BACKGROUND: CDUs are poised to increase efficiency and resource utilization. However, the optimal testing strategy that would assure favorable outcomes while decreasing cost is not defined. METHODS: 1016 subjects from 2 locations were propensity score-matched (PSM) by age, gender, pre-test likelihood, Duke treadmill score, and test results. Outcomes were length of stay >24 hours, MACE (acute coronary syndrome, revascularization, cardiac death), downstream resource use (admission for chest pain, repeat testing, angiography), and mean direct cost per patient. RESULTS: PSM yielded 680 patients (340 matches). 98% of all tests were normal. 96.6% of patients were discharged from the CDU within 24 hours but twice as many exceeded 24 hours in the sMPI group. There were no cardiac deaths. MACE rate was 1.47% at 72 hours and 1% at 1 year. Downstream resource use was 4.82% at 72 hours, and 7.69% at 1 year. The sMPI group was event-free longer than the ETT group reflecting less repeat testing. The mean direct cost was 30% higher for sMPI ($3168.70) vs. ETT ($2226.96). CONCLUSION: Low-risk chest pain patients in the observation unit had low MACE rate, not different for ETT vs. sMPI. The majority of ETT and sMPI tests were normal. The sMPI reduced additional testing, but resulted in greater expense and longer stay.

A prospective feasibility trial of a novel intravascular catheter system with retractable coiled tip guidewire placed in difficult intravascular access (DIVA) patients in the Emergency Department.

The primary study objective was to evaluate insertion success rates. Secondary objectives included patient satisfaction, procedure time, complication rates, completion of therapy and dwell time of the novel AccuCath® 2.25″ Blood Control (BC) Catheter System (FDA approved) placed in difficult-access patients. This was a single-arm feasibility trial evaluating the AccuCath® 2.25″ BC Catheter System in a convenience sample of DIVA patients defined as at least two failed initial attempts or a history of difficult access plus the inability to directly visualize or palpate a target vein. All enrolled patients were 18 years of age or older. A total of 120 patients were enrolled. These patients had an average of 3.7 and median of 3 prior attempts at vascular access prior to AccuCath placement. Successful access was gained in 100% of the patients, 77% on the first attempt and all within three attempts; 88.5% of patients completed therapy, with the remaining 12.5% experiencing minor complications that required discontinuation of the catheter. The average patient satisfaction score on a 5-point Likert scale was highly positive at 4.6. Preliminary results show that the AccuCath® 2.25″ BC Catheter System has excellent success rates in gaining vascular access in an extremely difficult patient population. The device did not lead to any significant complications. Patients were also very satisfied with the procedure.

A retrospective study of pulseless electrical activity, bedside ultrasound identifies interventions during resuscitation associated with improved survival to hospital admission. A REASON Study.

OBJECTIVE: Our objective was to determine whether organized or disorganized cardiac activity is associated with increased survival in patients who present in pulseless electrical activity (PEA) treated with either 1) standard advanced cardiac life support (ACLS) medications or 2) other interventions. METHODS: This was a secondary analysis of a prospective, multi-center observational study utilizing ultrasound in out-of-hospital or inemergency department PEA arrest. Bedside ultrasound was performed as ACLS protocol started and during pulse checks. Only cases with visible cardiac activity on ultrasound were included in the present analysis. Cardiac activity was categorized as disorganized (agonal twitching) or organized (contractions with changes in ventricular dimensions). Patients were categorized as receiving either standard bolus ACLS medications or alternative medications during the resuscitation (continuous adrenergic agents, thrombolytics, others). The primary outcome was survival to hospital admission. The secondary outcome was return of spontaneous circulation (ROSC). Multivariate modeling was performed to assess association between survival to hospital admission in patients with intravenous adrenergic agents and cardiac activity. RESULTS: In our cohort of 225 patients in PEA cardiac arrest with cardiac activity on ultrasound, the overall survival rate was higher in patients with organized cardiac activity than with disorganized cardiac activity. PEA cardiac arrest patients with organized cardiac activity treated with standard ACLS interventions demonstrated improved survival to hospital admission compared to those with disorganized activity (37.7% (95%CI 24.8-50.2%) versus 17.9% (95%CI 10.9-28%). PEA cardiac arrest patients with organized cardiac activity who received continuous adrenergic agents during the resuscitation and prior to ROSC demonstrated higher survival to hospital admission 45.5% (95%CI 26.9-65.4%) and ROSC 90.9% (95%CI 71.0-98.7%) compared to those with disorganized cardiac activity who received continuous adrenergic agents during the resuscitation 0% (95%CI 0-23.0%) and 47.1% (95%CI 26-69%). Regression analysis demonstrates an association between increased survival in patients receiving intravenous adrenergic agents and organized cardiac activity. CONCLUSION: Survival in patients following PEA arrest is higher in patients with organized cardiac activity. The initiation of continuous adrenergic agents during PEA was associated with improved survival to hospital admission in patients with organized cardiac activity on bedside ultrasound, but this improvement was not seen in patients in PEA with disorganized cardiac activity. Bedside ultrasound may identify a subset of patients that respond differently to ACLS interventions.

Emergency department point-of-care ultrasound in out-of-hospital and in-ED cardiac arrest.

BACKGROUND: Point-of-care ultrasound has been suggested to improve outcomes from advanced cardiac life support (ACLS), but no large studies have explored how it should be incorporated into ACLS. Our aim was to determine whether cardiac activity on ultrasound during ACLS is associated with improved survival. METHODS: We conducted a non-randomized, prospective, protocol-driven observational study at 20 hospitals across United States and Canada. Patients presenting with out-of-hospital arrest or in-ED arrest with pulseless electrical activity or asystole were included. An ultrasound was performed at the beginning and end of ACLS. The primary outcome was survival to hospital admission. Secondary outcomes included survival to hospital discharge and return of spontaneous circulation. FINDINGS: 793 patients were enrolled, 208 (26.2%) survived the initial resuscitation, 114 (14.4%) survived to hospital admission, and 13 (1.6%) survived to hospital discharge. Cardiac activity on US was the variable most associated with survival at all time points. On multivariate regression modeling, cardiac activity was associated with increased survival to hospital admission (OR 3.6, 2.2-5.9) and hospital discharge (OR 5.7, 1.5-21.9). No cardiac activity on US was associated with non-survival, but 0.6% (95% CI 0.3-2.3) survived to discharge. Ultrasound identified findings that responded to non-ACLS interventions. Patients with pericardial effusion and pericardiocentesis demonstrated higher survival rates (15.4%) compared to all others (1.3%). CONCLUSION: Cardiac activity on ultrasound was the variable most associated with survival following cardiac arrest. Ultrasound during cardiac arrest identifies interventions outside of the standard ACLS algorithm.

Use of Point-of-Care Ultrasound in the Emergency Department: Insights From the 2012 Medicare National Payment Data Set.

OBJECTIVES: Point-of-care ultrasound is a valuable tool with potential to expedite diagnoses and improve patient outcomes in the emergency department. However, little is known about national patterns of adoption. This study examined nationwide point-of-care ultrasound reimbursement among emergency medicine (EM) practitioners and examined regional and practitioner level variations. METHODS: Data from the 2012 Center for Medicare and Medicaid Services Fee-for-Service Provider Utilization and Payment Data include all practitioners who received more than 10 Medicare Part B fee-for-service reimbursements for any Healthcare Common Procedure Coding System code in 2012. Odds ratios (ORs) and descriptive statistics were calculated to assess relationships between ultrasound reimbursement and practice location, nearby presence of an EM residency, and time elapsed since practitioner graduation. RESULTS: Of 52,928 unique EM practitioners, 391 (0.7%) received limited ultrasound reimbursements for a total of 16,389 scans in 2012. Urban counties had an OR of 5.4 (95% confidence interval, 3.8-7.8) for receiving point-of-care ultrasound reimbursements compared to rural counties. Counties with an EM residency had an OR of 84.7 (95% confidence interval, 42.6-178.8) for reimbursement compared to counties without. The OR for receiving reimbursement was independent of medical school graduation year (P = .83); however, recent graduates performed more scans (P = .02). CONCLUSIONS: A small minority of EM practitioners received reimbursements for point-of-care ultrasound from Medicare beneficiaries. These practitioners were more likely to reside in urban and academic settings. Future efforts should assess the degree to which our findings reflect either low point-of-care ultrasound use or low rates of billing for ultrasound examinations that are performed.

Goal-directed Focused Ultrasound Milestones Revised: A Multiorganizational Consensus.

In 2012 the Accreditation Council for Graduate Medical Education and the American Board of Emergency Medicine released the emergency medicine milestones. The Patient Care 12 (PC12) subcompetency delineates staged and progressive accomplishment in emergency ultrasound. While valuable as an initial framework for ultrasound resident education, there are limitations to PC12. This consensus paper provides a revised description of criteria to define the subcompetency. A multiorganizational task force was formed between the American College of Emergency Physicians Ultrasound Section, the Council of Emergency Medicine Residency Directors, and the Academy of Emergency Ultrasound of the Society for Academic Emergency Medicine. Representatives from each organization created this consensus document and revision.

Seldinger Technique for Placement of "Peripheral" Internal Jugular Line: Novel Approach for Emergent Vascular Access.

This is a case report describing the ultrasound-guided placement of a peripheral intravenous catheter into the internal jugular vein of a patient with difficult vascular access. Although this technique has been described in the past, this case is novel in that the Seldinger technique was used to place the catheter. This allows for safer placement of a longer catheter (2.25″) without the need for venous dilation, which is potentially hazardous.
