Updating a Healthcare System-wide Clinical Pathway for Managing Chest Pain and Acute Coronary Syndromes.

Clinical pathways are useful tools for conveying and reinforcing best practices to standardize care and optimize patient outcomes across myriad conditions. The NewYork-Presbyterian Healthcare System has utilized a clinical chest pain pathway for more than 20 years to facilitate the timely recognition and management of patients presenting with chest pain syndromes and acute coronary syndromes. This chest pain pathway is regularly updated by an expanding group of key stakeholders, which has extended from the Columbia University Irving Medical Center to encompass the entire regional healthcare system, which includes 8 hospitals. In this 2023 update of the NewYork-Presbyterian clinical chest pain pathway, we present the key changes to the healthcare system-wide clinical chest pain pathway.

Computed Tomography Utilization for Patients Presenting with Chest Pain.

INTRODUCTION: Computed tomography (CT) is routinely used in the emergency department (ED) due to its ease of access and its ability to rapidly rule in or out many serious conditions. Freestanding emergency departments (FSEDs) have become increasingly used as an alternative to hospital-based emergency departments (HBEDs). The objective of this study was to investigate if the utilization rate of CT differs between FSEDs and HBEDs for chest pain. METHODS: A retrospective evaluation of patients presenting to 17 EDs within a large integrated healthcare system between May 1, 2019 - April 30, 2021 with a chief complaint chest pain. Categorical variables are presented as frequencies and percentages. Continuous variables are presented as mean and standard deviation. Multiple logistic regression was used to assess the effect of facility on CT utilization for chest pain. RESULTS: There were 67,084 patient encounters included in the study. Patients were predominately female (55%), white (61%), and insured through Medicare/Medicaid (59%). After controlling for predictive variables which included Charlson Comorbidity Index, ESI, age, sex, and race, patients who presented to FSEDs with chest pain were less likely to have a CT than those who presented to a HBED (AOR = 0.85, CI (0.81-0.90). CONCLUSION: CT scans of the chest are utilized less frequently at FSEDs compared to HBEDs for patient presenting with chest pain.

A Real-World Experience: Retrospective Review of Point-of-Care Ultrasound Utilization and Quality in Community Emergency Departments.

INTRODUCTION: Point-of-care ultrasound (POCUS) is commonly used in the emergency department (ED) as a rapid diagnostic tool. Emergency medicine (EM) has been an early adopter of POCUS with indications expanding over the last 10 years. While the literature describes widespread use among academic sites, there is little data on clinical POCUS utilization at non-academic EDs. We sought to describe community emergency physician (EP) use of POCUS by quantifying the number and type of studies performed, characteristics of the performing physician, and quality metrics. METHODS: Prior to the study period, all EPs underwent a standardized training and credentialing program. A retrospective review of all POCUS studies across 11 non-academic EDs from October 1, 2018-September 30, 2020 was performed by fellowship-trained physicians, who identified physician, exam type, and residency graduation year. The studies were then cross-referenced with quality review reports that assessed image acquisition, image interpretation, and image labeling. We performed descriptive statistics. RESULTS: During the study period, 5,099 POCUS studies were performed by 170 EPs. Exams most frequently performed were cardiac (24%), focused assessment of sonography in trauma (21.7%), and pregnancy (16.2%). Recent EM residency graduates (<10 years) were higher utilizers of POCUS with a group mean of 1.3 exams per 100 patients. Of the studies done, 86% had no quality issues. CONCLUSION: Community POCUS demonstrates a heavy focus on core exams performed by recent EM residency graduates with minimal quality issues after a standardized training program. This study is the first to quantify actual community POCUS use in multiple EDs and may impact credentialing and skills maintenance requirements.

Universal suicide screening in emergency departments across a large healthcare system.

BACKGROUND: Suicidal ideation is a common complaint in Emergency Departments (EDs) across the United States (US) and is an important preventable cause of death. Consequently, current Joint Commission guidelines require screening high-risk patients and those with behavioral health needs for suicide. Accordingly, we implemented universal suicide screening for all patients presenting to EDs in our healthcare system and sought to describe the characteristics of the identified "high-risk" patients. We also sought to determine whether universal suicide screening was feasible and what its impact was on ED length of stay (LOS). METHODS: All ED encounters in the healthcare system were assessed. Data were collected from February 1, 2020, through June 30, 2022. All patients aged 18 and over were screened using the Columbia Suicide Severity Rating Scale (C-SSRS) and categorized as no risk, low risk, moderate risk, and high risk. Encounters were then grouped into 'high risk" and "not high risk," defined as no, low, and moderate risk patients. Data collected included gender, discharge disposition, LOS, and insurance status. RESULTS: A total of 1,058,735 patient encounter records were analyzed. The "high risk" group (n = 11,359; 10.7%) was found to have a higher proportion of male patients (50.9 vs 43.7%) and government payors (71.6 vs. 67.1%) and a higher ED LOS [medians 380 min vs. 198 min] than the not high-risk group (p ≤0.001). Those with suicidal ideation comprised 0.73-1.58% of ED encounters in a given month. A secondary analysis of 2,255,616 ED encounter records from January 2019 - June 30, 2022, revealed that 40,854 (1.81%) encounters required 1:1 observation. The proportion of 1:1 observations in 2019, the year before implementation, was 1.91%. Using a non-inferiority margin of 25%, we found that the proportion of 1:1 patients in 2020, the year following implementation, was non-inferior to (no worse than) the previous year at 2.09% and decreased from 2021 to 2022 (1.69% and 1.57% respectively). CONCLUSION: Implementing universal suicide screening in all EDs within a healthcare system is feasible. The percentage of patients who screened high risk was under 5% of the overall ED population. While the median LOS was longer for "high-risk" patients than for the general ED population, it was not excessively so. Adequate staffing to properly maintain the safety of these patients is paramount.

Agitation Management in the Emergency Department with Physical Restraints: Where Do These Patients End Up?

INTRODUCTION: Agitation is frequently encountered in the emergency department (ED) and can range from psychomotor restlessness to overt aggression and violent behavior. Among all ED patients, 2.6% present with agitation or become agitated during their ED visit. We aimed to determine ED disposition for patients requiring agitation management with physical restraints. METHODS: This was a retrospective cohort of all adult patients who presented to one of 19 EDs in a large integrated healthcare system and received agitation management with physical restraints between January 1, 2018-December 31, 2020. Categorical variables are presented as frequency and percentages, and continuous variables are presented as medians and interquartile range. RESULTS: There were 3,539 patients who had agitation management with physical restraints included in this study. In total 2,076 (58.8%) were admitted to the hospital (95% CI [confidence interval] 0.572-0.605), and of those 81.4% were admitted to a primary medical floor and 18.6% were medically cleared and admitted to a psychiatric unit. Overall, 41.2% were able to be medically cleared and discharged from the ED. Mean age was 40.9 years, 2,140 were male (59.1%), 1,736 were White (50.3%), and 1,527 (43%) were Black. We found 26% had abnormal ethanol, (95% CI 0.245-0.274) and 54.6% had an abnormal toxicology screen (95% CI 0.529-0.562). A significant number were administered a benzodiazepine or antipsychotic in the ED (88.44%) (95% CI 0.874-0.895). CONCLUSION: The majority of patients who had agitation management with physical restraints were admitted to the hospital; of those patients, 81.4% were admitted to a primary medical floor and 18.6% were admitted to a psychiatric unit.

Post-intubation analgesia and sedation following succinylcholine vs. rocuronium in the emergency department.

BACKGROUND: Succinylcholine and rocuronium are the most commonly utilized neuromuscular blocker agents (NMBAs) for rapid sequence intubation (RSI) in the emergency department (ED). The duration of action of rocuronium is significantly longer (∼30 min) compared to succinylcholine (∼10 min) and previous studies have shown that patients receiving rocuronium are more likely to have longer time to sedation initiation following RSI. Furthermore, patients receiving rocuronium may be more likely to experience awareness with paralysis than those receiving succinylcholine. The primary goal for this study was to evaluate the association between NMBA use during RSI and post-intubation sedation and analgesia practices in the ED. METHODS: This was a retrospective, multicenter cohort study including patients 18 years and older that received succinylcholine or rocuronium during RSI in the ED between September 1, 2020 and August 31, 2021. Patients were excluded if they were intubated prior to ED arrival, experienced an out-of-hospital or in ED cardiac arrest, or received sugammadex within 60 min of rocuronium administration. Patients were screened in reverse chronological order until the targeted sample size was achieved and all data was abstracted from the electronic health record. The primary outcome was the time to initiation of analgesia or sedation. Secondary outcomes included dose of sedatives or analgesia administered at 30- and 60 min, and medications administered for post-intubation sedation or analgesia. FINDINGS: A total of 200 ED patients were included of which 100 received succinylcholine and 100 received rocuronium. There was no difference in the median time to initiation of analgesia or sedation between the succinylcholine and rocuronium groups (10 vs 8.5 min, p = 0.82) or in Kaplan-Meier cumulative probabilities (p = 0.17). At 60 min post-RSI, those receiving succinylcholine received significantly higher median doses of propofol (20 µg/kg/min vs. 10 µg/kg/min; p = 0.02) and fentanyl [100 µg vs. 84.2 µg; p = 0.02]. CONCLUSION: While no differences were observed in the time to initiation of post-intubation sedation or analgesia in ED patients receiving succinylcholine compared to rocuronium, differences in the intensity of post-intubation regimens was observed. Further investigation is needed to evaluate the adequacy of sedation following RSI in the ED.

Patients utilizing emergency medical services - Does facility type matter?

BACKGROUND: Emergency departments (EDs) play a critical role in the US healthcare system. As freestanding EDs (FSEDs) are integrated into the acute care landscape, local EMS providers are transporting to these facilities, which may be closer in proximity and provide faster turnaround times. We hypothesized that patients transported via EMS to a freestanding ED required fewer tests and are admitted less frequently than those transported to a HBED. Our objective was to compare testing frequency and admission rates between patients transported via EMS to a FSED vs. HBED. METHODS: This was a retrospective cohort study of all patients who presented within a large integrated hospital system via EMS to one of 10 HBEDs or one of 6 FSEDs between April 1, 2020 - May 1, 2021. Categorical variables are presented as frequencies and percentages and comparisons between groups were obtained using chi squared tests. Continuous variables are presented as mean and standard deviation and p-values comparing groups were obtained using t-tests. Multiple logistic regression was used to assess the effect of ED type on admission status, labs ordered, and testing performed. RESULTS: A total of 123,120 encounters were included in our study. Mean age at the FSEDs was 59.9 vs. 61.3 at the HBEDs. At the FSEDs 55.6% (n = 4675) were female vs. 53.0% (n = 60,809) at the HBEDs. At the FSEDs 82.0% (n = 6805) were White vs. 60.7% (n = 68,430) at the HBEDs. We found 50.0% (n = 3974) had Medicare at the FSEDs vs 50.9% (n = 55,372) at the FSEDs. At the FSEDs, 69.5% (n = 5846) had bloodwork vs. 82.4% (n = 94,512) at the HBEDs; 68.3% (n = 5745) had an x-ray at the FSEDs vs. 70.7% (n = 81,089) at the HBEDs; 40.1% (n = 3370) had a CT scan at the FSEDs vs. 44.9% (n = 51,503) at the HBEDs; and 40.6% (n = 3412) were admitted at the FSEDs vs. 56.1% (n = 64,355) at the HBEDs. After controlling for Charlson Comorbidity Index, acuity, age, gender, sex, insurance and race, patients in FSEDs were 35% less likely to be admitted as compared to HBEDs. CONCLUSION: Patients brought in via EMS to a FSED were less likely to have blood work, x-ray, or CT scan, and were less likely to be admitted to the hospital than those transported to a HBED.

White Paper: Best Practices in the Communication and Management of Actionable Incidental Findings in Emergency Department Imaging.

PURPOSE: Actionable incidental findings (AIFs) are common in radiologic imaging. Imaging is commonly performed in emergency department (ED) visits, and AIFs are frequently encountered, but the ED presents unique challenges for communication and follow-up of these findings. The authors formed a multidisciplinary panel to seek consensus regarding best practices in the reporting, communication, and follow-up of AIFs on ED imaging tests. METHODS: A 15-member panel was formed, nominated by the ACR and American College of Emergency Physicians, to represent radiologists, emergency physicians, patients, and those involved in health care systems and quality. A modified Delphi process was used to identify areas of best practice and seek consensus. The panel identified four areas: (1) report elements and structure, (2) communication of findings with patients, (3) communication of findings with clinicians, and (4) follow-up and tracking systems. A survey was constructed to seek consensus and was anonymously administered in two rounds, with a priori agreement requiring at least 80% consensus. Discussion occurred after the first round, with readministration of questions where consensus was not initially achieved. RESULTS: Consensus was reached in the four areas identified. There was particularly strong consensus that AIFs represent a system-level issue, with need for approaches that do not depend on individual clinicians or patients to ensure communication and completion of recommended follow-up. CONCLUSIONS: This multidisciplinary collaboration represents consensus results on best practices regarding the reporting and communication of AIFs in the ED setting.

Association between emergency department sepsis order set design and delay to second dose piperacillin-tazobactam administration.

BACKGROUND: Delay to first antibiotic dose in patients with sepsis has been associated with increased mortality. Second dose antibiotic delay has also been linked to worsened patient outcomes. Optimal methods to decrease second dose delay are currently unclear. The primary objective of this study was to evaluate the association between updating an emergency department (ED) sepsis order set design from one-time doses to scheduled antibiotic frequencies and delay to administration of second piperacillin-tazobactam dose. METHODS: This retrospective cohort study was conducted at eleven hospitals in a large, integrated health system and included adult patients treated in the ED with at least one dose of piperacillin-tazobactam ordered through an ED sepsis order set over a two year period. Patients were excluded if they received less than two doses of piperacillin-tazobactam. Midway through the study period, the enterprise-wide ED sepsis order set was updated to include scheduled antibiotic frequencies. Two patient cohorts receiving piperacillin-tazobactam were compared: those in the year before the order set update and those in the year post-update. The primary outcome was major delay, defined as an administration delay >25% of the recommended dosing interval, which was evaluated with multivariable logistic regression and interrupted time series analysis. RESULTS: 3219 patients were included: 1222 in the pre-update group and 1997 in the post-update group. The proportion of patients who experienced major second dose delay was significantly lower in the post-update group (32.7% vs 25.6%, p < 0.01; adjusted OR 0.64, 95% CI 0.52 to 0.78). No between-group difference was detected in the slope of monthly major delay frequency, but there was a significant level change (post-update change -10%, 95% CI -17.9% to -1.9%). CONCLUSIONS: Including scheduled antibiotic frequencies in ED sepsis order sets is a pragmatic mechanism to decrease delays in second antibiotic doses.

Multidisciplinary Approach to Improve Human Immunodeficiency Virus and Syphilis Testing Rates in Emergency Departments.

Background: Best practice guidelines recommend that patients at risk for sexually transmitted infections (STIs), such as gonorrhea (GC) and chlamydia, should also be tested for human immunodeficiency virus (HIV) and syphilis. This prospective quality assurance study aimed to increase HIV and syphilis testing rates in emergency departments (EDs) across the Cleveland Clinic Health System from January 1, 2020 through January 1, 2022. Methods: A multidisciplinary team of emergency medicine, infectious diseases, pharmacy, and microbiology personnel convened to identify barriers to HIV and syphilis testing during ED encounters at which GC/chlamydia were tested. The following interventions were implemented in response: rapid HIV testing with new a workflow for results follow-up, a standardized STI-screening order panel, and feedback to clinicians about ordering patterns. Results: There were 57 797 ED visits with GC/chlamydia testing completed during the study period. Human immunodeficiency virus testing was ordered at 5% of these encounters before the interventions were implemented and increased to 8%, 23%, and 36% after each successive intervention. Syphilis testing increased from 9% before the interventions to 12%, 28%, and 39% after each successive intervention. In multivariable analyses adjusted for age, gender, and location, the odds ratio for HIV and syphilis testing after all interventions was 11.72 (95% confidence interval [CI], 10.82-12.71; P ≤.001) and 6.79 (95% CI, 6.34-7.27; P ≤.001), respectively. Conclusions: The multidisciplinary intervention resulted in improved testing rates for HIV and syphilis.

Acute transverse myelitis progressing to permanent quadriplegia following COVID-19 infection.

As of January 2022, there have been over 350 million confirmed cases of COVID-19 in the world. The most common symptoms in those infected are fever, cough, malaise, and myalgia, however pulmonary, hematologic, gastrointestinal, renal, and neurologic complications have also been reported. Acute transverse myelitis (ATM) is an uncommon neurological syndrome characterized by acute or subacute spinal cord dysfunction that can lead to paresthesias, sensory and autonomic impairment, and even paralysis. Etiologies are often unclear; however, potential causes include infection, neoplastic, drug or toxin induced, autoimmune, and acquired. Treatment for ATM primarily consists of steroids and plasmapheresis, which often reverses any neurologic symptoms. ATM has rarely been reported as a complication of COVID-19 infections. A 43-year-old female presented to the emergency department for evaluation of progressive numbness and tingling in her legs ten days after developing upper respiratory symptoms from a COVID-19 infection. Physical examination and magnetic resonance imaging confirmed a diagnosis of ATM. During her hospital course, she experienced rapid progression of her paresthesias and developed complete loss of motor function in her upper and lower extremities. Within 48 hours after emergency department arrival, she required intubation due to worsening diaphragmatic and chest wall paralysis. Her treatment included a long-term steroid regimen and plasmapheresis, and unfortunately, she did not have any neurologic recovery. We present a very rare case of ATM progressing to complete quadriplegia following COVID-19 infection.

Reduced mortality and faster treatment in sepsis seen at freestanding vs. hospital-based emergency departments.

INTRODUCTION: Freestanding Emergency Departments (FEDs) have grown in number and understanding their impact on the healthcare system is important. Sepsis causes significant morbidity and mortality and identifying how FEDs impact sepsis morbidity and mortality has not been studied. The objective of this study was to determine if there is a difference in in-hospital mortality for sepsis patients who present initially to FEDs compared to a hospital-based ED. METHODS: This was a retrospective cohort of adult patients seen at a hospital-based ED or one of three FEDs within a large hospital system from 1/1/2018-10/31/2020. We included those who were diagnosed with sepsis, severe sepsis or septic shock and evaluated ED throughput measures, in-hospital mortality, and hospital length of stay. Categorical variables are presented as frequencies and percentages. Continuous variables are presented as mean and standard deviations or median and quartiles depending on distribution. Multiple logistic regression was fit to compare in-hospital mortality rates between the two groups. Variables controlled for included Charlson Comorbidity Index, race, gender, insurance, and sepsis severity. Wilcoxon rank sum tests were used to compare the time metrics. RESULTS: There were 1955 patients included in the study. Mean age of participants was 61.9 at the FEDs vs 63.7 at the HBED. Majority of the participants were white; 88.2% at the FED vs. 77.3% at the HBED; and male 49.0% at the FED vs. 51.1% at the HBED. Most patients had Medicare; 45.4% at the FED vs. 58.3% at the HBED. In-patient mortality rate was significantly lower for patients that presented to FEDs compared to HBED (95%CI 0.13-0.46) adjusted odds ratio 0.24. Time to IV fluids, time to lactate, time to blood cultures, time to ED disposition, ED LOS, time to arrival on the inpatient unit were all significantly lower for FEDs vs HBED (p < 0.05). CONCLUSION: Patients presenting to FEDs for sepsis, severe sepsis and septic shock had lower inpatient mortality, quicker treatment times, and were transferred and admitted to the hospital faster than patients seen at a HBED.

Improved hospital mortality rates after the implementation of emergency department sepsis teams.

INTRODUCTION: Sepsis is a leading cause of mortality with more than 700,000 hospitalizations and 200,000 deaths annually in the United States. Early recognition of sepsis is critical for timely initiation of treatment and improved outcomes. We sought to evaluate. in-hospital mortality rates of patients diagnosed with sepsis before and after implementation of emergency department (ED) sepsis teams. METHODS: This was a retrospective study of adult patients seen at a tertiary care ED diagnosed with sepsis and severe sepsis. Pre-implementation study time frame was 5/1/2018-4/30/2019 and post-implementation was 11/1/2019-9/30/2020. A six-month washout period was utilized after implementation of ED-based sepsis teams. Indications for sepsis team activation were: two systemic inflammatory response syndrome (SIRS) criteria with suspected infection or two SIRS with confirmed infection during workup. Categorical variables are presented as frequencies and percentages. Continuous variables are presented as mean and standard deviation or median and quartiles depending on distribution. Multiple logistic regression compared mortality rates pre- and post-implementation while controlling for Charlson comorbidity index. Secondary objectives included comparing time metrics pre- and post-implementation. Student t-tests compared normally distributed variables and Wilcoxon rank sum tests compared non-normally distributed variables. RESULTS: There were 1188 participants included in the study; 553 before implementation of sepsis teams and 635 after implementation. Mean age of participants was 64 years. Patients were 74.7% white and 22.6% black. Medicare was the most common health insurance (59%). Mortality rates were significantly lower post-implementation of sepsis teams compared to pre-implementation with an adjusted odds ratio of 0.472, (95%CI, 0.352-0.632). ED LOS (95%CI (-67.2--11.3), hospital LOS (95%CI, -1.0--0.002) and time to lactic acid (95%CI, -10.0- -3.0) and antibiotics (95%CI, -29.0--11.0) were all significantly lower after implementation. CONCLUSION: Implementation of ED sepsis teams decreased inpatient hospital mortality rates, ED length of stay and hospital length of stay.

The use of a pediatric appendicitis pathway in a large integrated health system reduced computed tomography imaging in the ED.

BACKGROUND: Appendicitis is the most common cause of an acute surgical abdomen in children. Diagnosis is often challenging as few pediatric patients present with classic symptoms. Clinicians are thus dependent on imaging to reach an accurate diagnosis. Although computerized tomography (CT) has high sensitivity and specificity, it has the disadvantage of imparting ionizing radiation. Ultrasound (US) is readily available and has comparable accuracy to CT when performed by experienced sonographers. We sought to examine the impact of a system-wide process improvement plan on CT use and other metrics in pediatric patients who presented to the Emergency Department (ED) with suspected appendicitis. METHODS: This is a retrospective study of the impact of a Pediatric Appendicitis Pathway (PAP) within a large integrated hospital system with 12 EDs including 3 designated hub EDs. Patients were placed in an initial risk category utilizing the Pediatric Appendicitis Score (PAS), and received US of the appendix at a hub ED if indicated by the PAS. Patients presenting to community EDs who required US appendix were transferred to hub EDs for imaging. Patients presenting in the 6-month pre-implementation period were compared to patients presenting in a 14-month post-implementation period on CT and US utilization, negative and missed appendectomy rates, and ED length of stay (LOS). RESULTS: 1874 patients (401 pre-PAP and 1473 post-PAP) were included in the study. At the hub EDs the rate of CT imaging for suspected appendicitis was reduced from 31% to 17% with a resultant increase in US utilization from 83% (333/401) to 90% (1331/1473) (p < 0.001). At community general EDs (404 pre-PAP and 449 post-PAP), the rate of CT was decreased from 45% (181/404) to 32%(144/449) (p < 0.001)) There was no significant change in the negative appendectomy rate pre-PAP (1/59 = 1.7%) and post-PAP (4/168 = 2.4%) (p = 0.99) at the hub EDs. There were no missed appendicitis cases after PAP implementation compared to 1 case in the pre-PAP period. Overall LOS was similar pre and post-PAP, however LOS was longer in patients that required transfer from community general EDs to hub EDs (median 264 vs 342 min, p < 0.001). CONCLUSIONS: A PAP that stratified patients into risk groups using the PAS and encouraged the use of US as a first line imaging modality, reduced the number of CT performed in a large integrated health system without significant changes to clinical outcomes. Furthermore, transferring select patients for an US as opposed to obtaining an initial CT in community general EDs was feasible and reduced CT use in the pediatric population.

Study of Haloperidol for Abdominal Pain in the Emergency Department (SHAPE).

INTRODUCTION: Intravenous haloperidol has been shown to decrease milligram morphine equivalents (MME) of analgesia and reduce hospital admissions for diabetic gastroparesis. The objective of this study was to evaluate whether haloperidol decreases MME for the treatment of non-specific abdominal pain diagnoses in the emergency department (ED), including gastroparesis, cyclic vomiting, cannabinoid hyperemesis syndrome, and unspecified abdominal pain. The primary outcome compared the difference in MME between encounters. Secondary outcomes included admission rate, pain scores, length of stay, rescue therapy administration, and adverse effects. METHODS: This retrospective chart review included patients ≥ 18 years old who presented to the ED. Patients must have had ≥ 2 ED encounters for abdominal pain, one in which they received conventional therapy with opioids (C-encounter), and the other in which they received haloperidol (H-encounter). Agitated patients were excluded. Seventy-five patients were needed to detect a 3 MME difference with 80% power and two-sided alpha of 0.05. RESULTS: We analyzed 107 patients with self-matched encounters. The median dose of haloperidol administered was 5.0 milligrams (mg) (interquartile range [IQR] 2.0 - 5.0). C-encounters had significantly more MME administered than H-encounters (median 5.7 mg [IQR 4.0 - 8.0] vs 0.0 mg [IQR 0.0 - 2.5], P < 0.001). These results remained significant despite route of haloperidol administration. C-encounters had higher rates of rescue therapy administration than H-encounters, (56% vs 33.6%, P < 0.001). There were higher rates of ketorolac administration in the H-encounter (P = 0.02). CONCLUSION: Encounters in which patients received haloperidol and ketorolac for abdominal pain had a statistically significant reduction in MME administered and lower rates of rescue therapy administration than encounters in which patients were treated with opioids.

Emergency Department Patients Who Leave Before Treatment Is Complete.

INTRODUCTION: Emergency department (ED) patients who leave before treatment is complete (LBTC) represent medicolegal risk and lost revenue. We sought to examine LBTC return visits characteristics and potential revenue effects for a large healthcare system. METHODS: This retrospective, multicenter study examined all encounters from January 1-December 31, 2019 at 18 EDs. The LBTC patients were divided into left without being seen (LWBS), defined as leaving prior to completed medical screening exam (MSE), and left subsequent to being seen (LSBS), defined as leaving after MSE was complete but before disposition. We recorded 30-day returns by facility type including median return hours, admission rate, and return to index ED. Expected realization rate and potential charges were calculated for each patient visit. RESULTS: During the study period 626,548 ED visits occurred; 20,158 (3.2%) LBTC index encounters occurred, and 6745 (33.5%) returned within 30 days. The majority (41.7%) returned in <24 hours with 76.1% returning in 10 days and 66.4% returning to index ED. Median return time was 43.3 hours, and 23.2% were admitted. Urban community EDs had the highest 30-day return rate (37.8%, 95% confidence interval, 36.41-39.1). Patients categorized as LSBS had longer median return hours (66.0) and higher admission rates (29.8%) than the LWBS cohort. There was a net potential realization rate of $9.5 million to the healthcare system. CONCLUSION: In our system, LSBS patients had longer return times and higher admission rates than LWBS patients. There was significant potential financial impact for the system. Further studies should examine how healthcare systems can reduce risk and financial impacts of LBTC patients.
