Impact of skilled nursing facility (SNF) 3-day hospitalization requirement waiver during the COVID-19 pandemic on emergency department and inpatient SNF discharges in California.

Objective: We sought to study the impact of the Centers for Medicare & Medicaid services (CMS) waiver of the 3-day hospitalization requirement for skilled nursing facility (SNF) care implemented as part of the Federal COVID-19 response on emergency department (ED) and inpatient hospital SNF discharges. Methods: We conducted a multicenter retrospective cohort study of hospital ED and inpatient visits in California during 18 months before (prewaiver, September 2018-February 2020) and 18 months after (waiver, March 2020-August 2021) waiver implementation. Data were collected from all adult ED and admitted patients utilizing California Department of Health Care Access and Information datasets from all acute care hospitals licensed in the state. Prewaiver and waiver periods were compared for SNF discharge/disposition rates stratified by patient demographic and hospital data with differences in the proportion and 95% confidence interval [CI] reported (SPSS). Results: SNF discharges decreased from the prewaiver to waiver periods from the ED (-7.4% [CI -8.1%, -6.6%]), along with larger declines occurring from the inpatient hospital setting (-18.1% [CI -18.4%, -17.9%]). For Medicare beneficiaries, there was a smaller decrease in ED SNF rates (-3.8% [CI -4.7%, -2.9%]), and there was no significant change for SNF discharge rates for inpatient admissions with a length of stay (LOS) <3 days (+1.0% [CI 0.0%, 2.1%]). Conclusion: In California, the CMS waiver did not result in an increase, but an actual decrease rate of SNF discharges from the ED and inpatient setting, though with smaller declines for the ED, Medicare patients, and those with a LOS <3 days.

Impact of Implementation of a New Weapons Screening at an Urban Emergency Department.

BACKGROUND: Violence in the emergency department (ED) setting is well documented in medical literature. Weapons can be used to cause significant injury or mortality, although there is a paucity of literature on weapons and weapons screening in the ED. OBJECTIVES: The purpose of this study was to assess the impact of initiating a weapons screening process on the identification and removal of weapons. METHODS: Multiple aspects of a weapons screening program were evaluated at 2 and 6 months prior to and after a weapons screening protocol was initiated at an urban ED. In the Pre-Screen periods, only patients primarily seeking care for mental health were screened prior to entry. In the Post-Screen periods, all patients and visitors were screened with walk-through magnetometers or wand metal detectors, and additional screening checks were initiated. The number of individuals screened and numbers of weapons found were measured. Descriptive statistics comparing Pre- and Post-Screen periods were performed. RESULTS: Prior to the new screening process, 511 and 1701 patients primarily seeking care for mental health were screened, with 15 and 103 weapons confiscated at 2 and 6 months, respectively. After the screening process was initiated, 13,149 and 43,321 ED patients and visitors were screened, with 194 and 567 weapons confiscated at 2 and 6 months, respectively. Persons screened increased by 25-fold at both 2 and 6 months after implementing the screening process. Weapons confiscated increased approximately 13-fold and sixfold at the respective 2- and 6-month Pre- and Post-Screen periods, respectively. CONCLUSION: Implementation of weapons screening significantly increased the number of weapons identified and confiscated prior to entry in the ED by patients and visitors.

Clinical and financial outcome impacts of comprehensive geriatric assessment in a level 1 geriatric emergency department.

BACKGROUND: The aging population has led to an increase in emergency department (ED) visits by older adults who have complex medical conditions and high social needs. The purpose of this study was to assess if comprehensive geriatric evaluation and management impacted service utilization and cost by older adults admitted to the ED. METHODS: This is a retrospective matched case-control study at a level 1 geriatric ED (GED) from January 1, 2018-March 31, 2020. Geriatric nurse specialists (GENIEs) provided comprehensive evaluations and management for GED patients. Propensity score matching was used to match patients receiving GENIE consultations to ED patients who did not receive a GENIE consult. Regression was used to assess the impact of the GENIE services on inpatient admissions, ED revisits and cost of inpatient and ED care from the payor perspective. RESULTS: GENIE consults were associated with a 13.0% reduction in absolute risk of admission through the ED at index (95% confidence interval [CI] -17.0%, -9.0%, p < 0.001) and a reduction in risk for total admissions at 30 and 90-days post discharge (-11.3%, 95% CI -15.6%, -7.1%, p-value < 0.001; and -10.0, 95% CI -13.8%, -6.0%; p < 0.001 respectively), both driven by reduced risk of admission at the index visit. GENIE consults were associated with a 4% increase in absolute risk of revisits to the ED within 30 days (95% CI 0.6%, 7.3%; p = 0.001). GENIE consults were associated with a decrease in cost of inpatient and ED care, with savings of $2344 within 30 days (95% CI $2247, $2441, p < 0.001) and savings of $2004 USD within 90 days (95% CI $1895, $2114, p < 0.001), driven by reduced costs at the index visit. CONCLUSIONS: GENIE consults were associated with decreased inpatient admissions through the ED, modestly increased ED revisits, and decreased cost of inpatient and ED care. The results of this study can be useful for EDs considering approaches to better serve older adults. They can also be of interest to payers as an area of potential cost savings.

Ransomware Attack Associated With Disruptions at Adjacent Emergency Departments in the US.

Importance: Cyberattacks on health care delivery organizations are increasing in frequency and sophistication. Ransomware infections have been associated with significant operational disruption, but data describing regional associations of these cyberattacks with neighboring hospitals have not been previously reported, to our knowledge. Objective: To examine an institution's emergency department (ED) patient volume and stroke care metrics during a month-long ransomware attack on a geographically proximal but separate health care delivery organization. Design, Setting, and Participants: This before and after cohort study compares adult and pediatric patient volume and stroke care metrics of 2 US urban academic EDs in the 4 weeks prior to the ransomware attack on May 1, 2021 (April 3-30, 2021), as well as during the attack and recovery (May 1-28, 2021) and 4 weeks after the attack and recovery (May 29 to June 25, 2021). The 2 EDs had a combined mean annual census of more than 70 000 care encounters and 11% of San Diego County's total acute inpatient discharges. The health care delivery organization targeted by the ransomware constitutes approximately 25% of the regional inpatient discharges. Exposure: A month-long ransomware cyberattack on 4 adjacent hospitals. Main Outcomes and Measures: Emergency department encounter volumes (census), temporal throughput, regional diversion of emergency medical services (EMS), and stroke care metrics. Results: This study evaluated 19 857 ED visits at the unaffected ED: 6114 (mean [SD] age, 49.6 [19.3] years; 2931 [47.9%] female patients; 1663 [27.2%] Hispanic, 677 [11.1%] non-Hispanic Black, and 2678 [43.8%] non-Hispanic White patients) in the preattack phase, 7039 (mean [SD] age, 49.8 [19.5] years; 3377 [48.0%] female patients; 1840 [26.1%] Hispanic, 778 [11.1%] non-Hispanic Black, and 3168 [45.0%] non-Hispanic White patients) in the attack and recovery phase, and 6704 (mean [SD] age, 48.8 [19.6] years; 3326 [49.5%] female patients; 1753 [26.1%] Hispanic, 725 [10.8%] non-Hispanic Black, and 3012 [44.9%] non-Hispanic White patients) in the postattack phase. Compared with the preattack phase, during the attack phase, there were significant associated increases in the daily mean (SD) ED census (218.4 [18.9] vs 251.4 [35.2]; P < .001), EMS arrivals (1741 [28.8] vs 2354 [33.7]; P < .001), admissions (1614 [26.4] vs 1722 [24.5]; P = .01), patients leaving without being seen (158 [2.6] vs 360 [5.1]; P < .001), and patients leaving against medical advice (107 [1.8] vs 161 [2.3]; P = .03). There were also significant associated increases during the attack phase compared with the preattack phase in median waiting room times (21 minutes [IQR, 7-62 minutes] vs 31 minutes [IQR, 9-89 minutes]; P < .001) and total ED length of stay for admitted patients (614 minutes [IQR, 424-1093 minutes] vs 822 minutes [IQR, 497-1524 minutes]; P < .001). There was also a significant increase in stroke code activations during the attack phase compared with the preattack phase (59 vs 102; P = .01) as well as confirmed strokes (22 vs 47; P = .02). Conclusions and Relevance: This study found that hospitals adjacent to health care delivery organizations affected by ransomware attacks may see increases in patient census and may experience resource constraints affecting time-sensitive care for conditions such as acute stroke. These findings suggest that targeted hospital cyberattacks may be associated with disruptions of health care delivery at nontargeted hospitals within a community and should be considered a regional disaster.

Physiological Effects of a Spit Restraint Device Saturated With Artificial Saliva.

BACKGROUND: Spit restraint devices, also referred to as spit hoods, spit masks, or spit socks, are used by law enforcement and medical personnel to minimize transmission of communicable disease from bodily fluids from agitated individuals. Several lawsuits have implicated spit restraint devices as contributing to the death of individuals who are physically restrained by means of asphyxiation due to saturation of the mesh restraint device with saliva. OBJECTIVES: This study aims to evaluate whether a saturated spit restraint device has any clinically significant effects on the ventilatory or circulatory parameters of healthy adult subjects. METHODS: Subjects wore a spit restraint device dampened with 0.5% carboxymethylcellulose, an artificial saliva. Baseline vitals were taken, and a wet spit restraint device was then placed over the subject's head, and repeat measurements were taken at 10, 20, 30, and 45 min. A second spit restraint device was placed 15 min after the first. Measurements at 10, 20, 30, and 45 min were compared with baseline using paired t-tests. RESULTS: The mean age of 10 subjects was 33.8 years, and 50% were female. There was no significant difference between baseline and while wearing the spit sock for 10, 20, 30, and 45 min for the measured parameters including heart rate, oxygen saturation, end-tidal CO2, respiratory rate, or blood pressure. No subject indicated respiratory distress or had to terminate the study. CONCLUSIONS: In healthy adult subjects, there were no statistically or clinically significant differences in ventilatory or circulatory parameters while wearing the saturated spit restraint.

Emergency Department-Initiated Buprenorphine Treatment in a Population with a High Rate of Homelessness: An Observational Study.

BACKGROUND: Buprenorphine is an effective treatment for opioid use disorders. A previous randomized trial comparing emergency department (ED)-initiated buprenorphine to standard care showed dramatic improvement in follow-up. This is encouraging, but must be replicated to understand the generalizability of buprenorphine treatment. OBJECTIVES: Evaluate the efficacy of an ED-initiated buprenorphine protocol similar to a previous randomized trial in a different population. METHODS: This ED-based descriptive study described the results of a project implementing an opioid use disorder treatment protocol that included buprenorphine. Patients with opioid use disorder were offered treatment with buprenorphine, a buprenorphine prescription whenever possible, and a follow-up visit to a clinic providing addiction treatment. The primary outcome was engagement in formal addiction treatment 30 days after the index visit. RESULTS: Of the 210 patients who accepted referral for outpatient medication-assisted treatment, 95 (45.2%) achieved the primary outcome. Two-thirds of these patients received a buprenorphine prescription at discharge; 40% were homeless. A regression analysis revealed one statistically significant predictor of the primary outcome: patients who were housed were 2.49 times more likely to engage in opioid use disorder treatment than patients who were homeless (p = 0.02). CONCLUSIONS: In this descriptive study of an ED-initiated buprenorphine protocol, follow-up was less than that reported in a previous randomized controlled trial. Two important differences between our study and the randomized trial are the high rate of homelessness and the fact that not every patient received a prescription for buprenorphine. The efficacy of ED-initiated treatment may depend on certain population characteristics.

Trends in emergency department visits associated with cannabis use among older adults in California, 2005-2019.

BACKGROUND: The use of cannabis among older adults is increasing in the United States. While cannabis use has been suggested to help alleviate chronic symptoms experienced by older adults, its potential adverse effects may lead to unintended consequences, including increased acute healthcare utilization related to its use. The objective of this study was to examine trends in cannabis-related emergency department (ED) visits in California. METHODS: Using data from the Department of Healthcare Access and Information, we conducted a trend analysis of cannabis-related ED visits from all acute care hospitals in California from 2005 to 2019. For each calendar year, we determined the cannabis-related ED visit rate per 100,000 ED visits for adults aged ≥65 utilizing primary or secondary diagnosis codes. We estimated the absolute and relative changes in overall cannabis-related visit rates during the study period and by subgroup, including age (65-74, 75-84, ≥85), race/ethnicity, sex, payer/insurance, Charlson comorbidity index score, and cannabis-related diagnosis code. RESULTS: The cannabis-related ED visit rate increased significantly for adults aged ≥65 and all subgroups (p < 0.001). The overall rate increased from 20.7 per 100,000 visits in 2005 to 395.0 per 100,000 ED visits in 2019, a 1804% relative increase. By race/ethnicity, older Black adults had the highest ED visit rate in 2019 and the largest absolute increase while older males had a higher ED visit rate in 2019 and a greater absolute increase than older women. Older adults with a higher Charlson score had a higher ED visit rate in 2019 and a larger absolute increase during the study period. CONCLUSION: Cannabis-related ED visits are increasing among older adults in California and are an adverse effect of cannabis use. Asking about cannabis use and providing education about its use should be a part of routine medical care for older adults.

A retrospective review of antibiotic use for acute respiratory infections in urgent-care patients.

Objective: We examined the use of antibiotics for acute respiratory infections in an urgent-care setting. Design: Retrospective database review. Setting: The study was conducted in 2 urgent-care clinics staffed by academic emergency physicians in San Diego, California. Patients: Visits for acute respiratory infections were identified based on presenting complaints. Methods: The primary outcome was a discharge prescription for an antibiotic. The patient and provider characteristics that predicted this outcome were analyzed using logistic regression. The variation in antibiotic prescriptions between providers was also analyzed. Results: In total, 15,160 visits were analyzed. The patient characteristics were not predictive of antibiotic treatment. Physicians were more likely than advanced practice practitioners to prescribe antibiotics (1.31; 95% confidence interval [CI], 1.21-1.42). For every year of seniority, a provider was 1.03 (95% CI, 1.02-1.03) more likely to prescribe an antibiotic. Although the providers saw similar patients, we detected significant variation in the antibiotic prescription rate between providers: the mean antibiotic prescription rate within the top quartile was 54.3% and the mean rate in the bottom quartile was 21.7%. Conclusions: The patient and provider characteristics we examined were either not predictive or were only weakly predictive of receiving an antibiotic prescription for acute respiratory infection. However, we detected a marked variation between providers in the rate of antibiotic prescription. Provider differences, not patient differences, drive variations in antibiotic prescriptions. Stewardship efforts may be more effective if directed at providers rather than patients.

Geriatric Falls: Patient Characteristics Associated with Emergency Department Revisits.

INTRODUCTION: Falls are the leading cause of traumatic injury among elderly adults in the United States, which represents a significant source of morbidity and leads to exorbitant healthcare costs. The purpose of this study was to characterize elderly fall patients and identify risk factors associated with seven-day emergency department (ED) revisits. METHODS: This was a multicenter, retrospective, longitudinal cohort study using non-public data from 321 licensed, nonfederal, general, and acute care hospitals in California obtained from the Department of Healthcare Access and Information from January 1-December 31, 2017. Included were patients 65 and older who had a fall-related ED visit identified by International Classification of Diseases codes W00x to W19x. Primary outcome was a return visit to the ED within a seven-day window following the index encounter. Demographics collected included age, gender, ethnicity/race, patient payer status, Charlson Comorbidity Index (CCI), psychiatric diagnoses, and alcohol/substance use disorder diagnoses. We performed multivariate logistic regression to identify characteristics associated with seven-day ED revisit. RESULTS: We identified a total of 2,758,295 ED visits during the study period with 347,233 (12.6%) visits corresponding to fall-related injuries. After applying exclusion criteria, 242,572 index ED visits were identified, representing 206,612 patients. Of these, 24,114 (11.7%) patients returned to an ED within seven days (revisit). Within this revisit population, 6,161 (22.6%) presented to a facility that was distinct from their index visit, and 4,970 (18.2%) were ultimately discharged with the same primary diagnosis as their index visit. Characteristics with the largest independent associations with a seven-day ED revisit were presence of a psychiatric diagnosis (odds ratio [OR] 1.75; 95% confidence interval [CI] 1.69 to 1.80), presence of an alcohol or substance use disorder (OR 1.70; 95% CI 1.64 to 1.78), and CCI ≥ 3 (OR 2.79; 95% CI 2.68 to 2.90). CONCLUSION: In this study we identified 24,114 elderly fall patients who experienced a seven-day ED revisit. Patients with multiple comorbidities, a substance use disorder, or a psychiatric diagnosis exhibited increased odds of experiencing a return visit to the ED within seven days of a fall-related index visit. These findings will help target at-risk elderly fall patients who may benefit from preventative multidisciplinary intervention during index ED visits to reduce ED revisits.

Urine testing is associated with inappropriate antibiotic use and increased length of stay in emergency department patients.

Background: Exposing patients with a low probability of disease to diagnostic testing with poor test characteristics leads to false positive results. Providers often act on these false results, which can cause unnecessary evaluation and treatment. The treatment of asymptomatic bacteriuria is discouraged, but it still frequently occurs in the inpatient setting; it is less studied in the Emergency Department (ED). In this study, we examine associations between urine testing, inappropriate antibiotic use, and length of stay in discharged ED patients at risk of urinary tract infection (UTI) misdiagnosis. Methods: A cohort of discharged ED patients at risk of UTI misdiagnosis was created by pulling visit information for patients presenting with abdominal pain, chest pain, headache, vaginal bleeding in pregnancy, and elderly females with weakness or confusion. Predictors of urine testing, and urinary tract infection treatment were determined with logistic regression analysis. A chart review of a representative sample of this cohort was then completed screening for the presence of urinary tract symptoms and urine culture results. Linear regression analysis was then used to generate an adjusted mean difference in length of stay between patients who had urine testing compared to those who did not. Results: About a quarter of chest pain and headache patients had urine testing, while approximately 75% of abdominal pain patients, vaginal bleeding in pregnancy, and elderly females with weakness or confusion did. Except for chest pain patients, the UTI treatment rate was more than double the positive culture rate, indicating overtreatment. A diagnosis of UTI is based on a combination of UTI symptoms and positive urine cultures, yet only about 15% of patients treated for UTI met these criteria. Lastly, in all chief complaint groups, the length of stay was significantly longer-30 min or more-for those who had urine testing compared to matched controls. Conclusions: In this observational study of patients at risk of UTI misdiagnosis, urine testing was associated with inappropriate antibiotic use and delayed discharge. There is pressure on providers to perform diagnostic testing, but in patients without specific UTI symptoms, urine testing might cause more harm than benefit.

Procalcitonin as a Predictive Tool for Death and ICU Admission among Febrile Neutropenic Patients Visiting the Emergency Department.

Background and Objectives: Risk stratification tools for febrile neutropenia exist but are infrequently utilized by emergency physicians. Procalcitonin may provide emergency physicians with a more objective tool to identify patients at risk of decompensation. Materials and Methods: We conducted a retrospective cohort study evaluating the use of procalcitonin in cases of febrile neutropenia among adult patients presenting to the Emergency Department compared to a non-neutropenic, febrile control group. Our primary outcome measure was in-hospital mortality with a secondary outcome of ICU admission. Results: Among febrile neutropenic patients, a positive initial procalcitonin value was associated with significantly increased odds of inpatient mortality after adjusting for age, sex, race, and ethnicity (AOR 9.912, p < 0.001), which was similar, though greater than, our non-neutropenic cohort (AOR 2.18, p < 0.001). All febrile neutropenic patients with a positive procalcitonin were admitted to the ICU. Procalcitonin had a higher sensitivity and negative predictive value (NPV) in regard to mortality and ICU admission for our neutropenic group versus our non-neutropenic control. Conclusions: Procalcitonin appears to be a valuable tool when attempting to risk stratify patients with febrile neutropenia presenting to the emergency department. Procalcitonin performed better in the prediction of death and ICU admission among patients with febrile neutropenia than a similar febrile, non-neutropenic control group.

Heat Waves and Emergency Department Visits Among the Homeless, San Diego, 2012-2019.

Objectives. To determine the effect of heat waves on emergency department (ED) visits for individuals experiencing homelessness and explore vulnerability factors. Methods. We used a unique highly detailed data set on sociodemographics of ED visits in San Diego, California, 2012 to 2019. We applied a time-stratified case-crossover design to study the association between various heat wave definitions and ED visits. We compared associations with a similar population not experiencing homelessness using coarsened exact matching. Results. Of the 24 688 individuals identified as experiencing homelessness who visited an ED, most were younger than 65 years (94%) and of non-Hispanic ethnicity (84%), and 14% indicated the need for a psychiatric consultation. Results indicated a positive association, with the strongest risk of ED visits during daytime (e.g., 99th percentile, 2 days) heat waves (odds ratio = 1.29; 95% confidence interval = 1.02, 1.64). Patients experiencing homelessness who were younger or elderly and who required a psychiatric consultation were particularly vulnerable to heat waves. Odds of ED visits were higher for individuals experiencing homelessness after matching to nonhomeless individuals based on age, gender, and race/ethnicity. Conclusions. It is important to prioritize individuals experiencing homelessness in heat action plans and consider vulnerability factors to reduce their burden.

Emergency Department Management of Chest Pain With a High-Sensitivity Troponin-Enabled 0/1-Hour Rule-Out Algorithm.

OBJECTIVES: The analytical sensitivity of high-sensitivity cardiac troponin T (hsTnT) assays has enabled rapid myocardial infarction rule-out algorithms for emergency department (ED) presentations. Few studies have analyzed the real-world impact of hsTnT algorithms on outcomes and operations. METHODS: Comparison of ED length of stay (LOS) and 30-day outcomes (return to ED, inpatient admission, and mortality) for patients presenting with chest pain during 2 separate 208-day periods using a 0/1-hour hsTnT-enabled algorithm or fourth-generation TnT. RESULTS: Discharge, 30-day readmission, and 30-day mortality rates were not significantly different with fourth-generation TnT vs hsTnT. Thirty-day return rates were significantly decreased with hsTnT (17.4% vs 14.9%; P < .01). For encounters with TnT measured at least twice and resulting in discharge, median ED LOS decreased by 61 minutes with the use of hsTnT (488 vs 427 minutes; P < .0001). Median time between first and second TnT results decreased by 82 minutes with hsTnT (202 vs 120 minutes; P < .0001), suggesting that the 0/1-hour algorithm was incompletely adopted. CONCLUSIONS: Implementation of the hsTnT algorithm was associated with decreased 30-day return rates and decreased ED LOS for a subset of patients, despite incomplete adoption of the 0/1-hour algorithm.

Cancer-related Emergency Department Visits: Comparing Characteristics and Outcomes.

INTRODUCTION: There is increasing appreciation of the challenges of providing safe and appropriate care to cancer patients in the emergency department (ED). Our goal here was to assess which patient characteristics are associated with more frequent ED revisits. METHODS: This was a retrospective cohort study of all ED visits in California during the 2016 calendar year using data from the California Office of Statewide Health Planning and Development. We defined revisits as a return visit to an ED within seven days of the index visit. For both index and return visits, we assessed various patient characteristics, including age, cancer type, medical comorbidities, and ED disposition. RESULTS: Among 12.9 million ED visits, we identified 73,465 adult cancer patients comprising 103,523 visits that met our inclusion criteria. Cancer patients had a 7-day revisit rate of 17.9% vs 13.2% for non-cancer patients. Cancer patients had a higher rate of admission upon 7-day revisit (36.7% vs 15.6%). Patients with cancers of the small intestine, stomach, and pancreas had the highest rate of 7-day revisits (22-24%). Cancer patients younger than 65 had a higher 7-day revisit rate than the elderly (20.0% vs 16.2%). CONCLUSION: In a review of all cancer-related ED visits in the state of California, we found a variety of characteristics associated with a higher rate of 7-day ED revisits. Our goal in this study was to inform future research to identify interventions on the index visit that may improve patient outcomes.

Evaluation of the ventilatory effects on human subjects in prolonged hip-flexed/head-down restraint position.

BACKGROUND: The restraint chair is a tool used by law enforcement and correction personnel to control aggressive, agitated individuals. When initiating its use, subjects are often placed in a hip-flexed/head-down (HFHD) position to remove handcuffs. Usually, this period of time is less than two minutes but can become more prolonged in particularly agitated patients. Some have proposed this positioning limits ventilation and can result in asphyxia. The aim of this study is to evaluate if a prolonged HFHD restraint position causes significant ventilatory compromise. METHODS: Subjects exercised on a stationary bicycle until they reached 85% of their predicted maximal heart rate. They were then handcuffed with their hands behind their back and placed into a HFHD seated position for five minutes. The primary outcome measurement was maximal voluntary ventilation (MVV). This was measured at baseline, after initial placement into the HFHD position, and after five minutes of being in the position while still maintaining the HFHD position. Baseline measurements were compared with final measurements for statistically significant differences. RESULTS: We analyzed data for 15 subjects. Subjects had a mean MVV of 165.3 L/min at baseline, 157.8 L/min after initially being placed into the HFHD position, and a mean of 138.7 L/min after 5 min in the position. The mean baseline % predicted MVV was 115%; after 5 min in the HFHD position the mean was 96%. This 19% absolute difference was statistically significant (p = 0.001). CONCLUSIONS: In healthy seated male subjects with recent exertion, up to five minutes in a HFHD position results in a small decrease in MVV compared with baseline MVV levels. Even with this decrease, mean MVV levels were still 96% of predicted after five minutes. Though a measurable decrease was found, there was no clinically significant change that would support that this positioning would lead to asphyxia over a five-minute time period.

Active Cancer Patients Presenting to the Emergency Department with Acute Venous Thromboembolism: A Retrospective Cohort Study on Risks and Outcomes.

BACKGROUND: There is no prior study that has documented emergency department (ED) outcomes or stratified mortality risks of cancer patients presenting with an acute venous thromboembolism (VTE). OBJECTIVE: To evaluate ED treatment of these patients, to document their outcomes, and to identify risk factors associated with death. METHODS: A retrospective cohort study was performed on active cancer patients presenting with deep venous thrombosis or pulmonary embolism to two academic EDs between July 2012 and June 2016. Key outcomes included mortality, ED revisit, and admission within 30 days. The patient cohort was characterized; crosstabs and regression analysis were performed to assess relative risks (RRs) and mitigating factors associated with 30-day mortality. RESULTS: Of 355 patients, 9% died and 38% had one or more ED revisits or admissions. Recent immobility (RR 2.341, 95% CI 1.227-4.465), poor functional status (RR 2.090, 95% CI 1.028-4.248), recent admission (RR 2.441, 95% CI 1.276-4.669), and metastatic cancer (RR 4.669, 95% CI 1.456-14.979) were major risk factors for mortality. ED-provided anticoagulation reduced the overall mortality risk (RR 0.274, 95% CI 0.146-0.515) and mitigated the risk from recent immobility (RR 1.250, 95% CI 0.462-3.381), especially among patients with good or fair functional status. CONCLUSION: Immobility and cancer morbidity are key risk factors for mortality after an acute VTE, but ED-provided anticoagulation mitigates the risk of immobility among healthier patients. Eastern Cooperative Oncology Group performance status can help clinicians risk stratify these patients at presentation.

Ethnic Disparities in COVID-19 Among Older Adults Presenting to the Geriatric Emergency Department.

BACKGROUND: There is a dearth of epidemiological data on ethnic disparities among older patients with COVID-19. The objective of this study was to characterize ethnic differences in clinical presentation and outcomes from COVID-19 among older U.S. adults. METHODS: This was a retrospective cohort study within two geriatric emergency departments (GEDs) at a large academic health system. One hundred patients 65 years or older who visited a GED between March 10, 2020 and August 9, 2020 and tested positive for COVID-19 were examined. Electronic medical records were used to determine presenting COVID-19-related symptoms, comorbidities, and clinical outcomes. Descriptive statistics are reported with associated 95% confidence intervals (CIs). RESULTS: In the overall sample, mean age was 75.9 years; 18% were 85 years or older; 50% were male; and 46.0% were Hispanic. Relative to non-Hispanic patients with COVID-19, Hispanic patients with COVID-19 had a higher percentage of shortness of breath (78.3% vs. 51.9%; difference: 26.4%; 95% CI 7.6-42.5%), pneumonia (82.6% vs. 50.0%; difference: 32.6%; 95% CI 14.1-47.9%), acute respiratory distress syndrome (13.0% vs. 1.9%; difference: 11.1%; 95% CI 0.7-23.9%), and acute kidney failure (41.3% vs. 22.2%; difference: 19.1%; 95% CI 0.9-36.0%). Rates of other poor outcomes, including hospitalization, intensive care unit (ICU) admission, return visits to the GED within 30 days of discharge, or death, did not significantly differ between Hispanic and non-Hispanic patients with COVID-19. CONCLUSIONS: These preliminary data show that older Hispanic patients relative to non-Hispanic patients with COVID-19 presenting to a GED did not experience worse outcomes, including hospitalization, ICU admission, 30-day return visits to the GED, or death.

Moving the needle on fall prevention: A Geriatric Emergency Care Applied Research (GEAR) Network scoping review and consensus statement.

BACKGROUND: Although falls are common, costly, and often preventable, emergency department (ED)-initiated fall screening and prevention efforts are rare. The Geriatric Emergency Medicine Applied Research Falls core (GEAR-Falls) was created to identify existing research gaps and to prioritize future fall research foci. METHODS: GEAR's 49 transdisciplinary stakeholders included patients, geriatricians, ED physicians, epidemiologists, health services researchers, and nursing scientists. We derived relevant clinical fall ED questions and summarized the applicable research evidence, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews. The highest-priority research foci were identified at the GEAR Consensus Conference. RESULTS: We identified two clinical questions for our review (1) fall prevention interventions (32 studies) and (2) risk stratification and falls care plan (19 studies). For (1) 21 of 32 (66%) of interventions were a falls risk screening assessment and 15 of 21 (71%) of these were combined with an exercise program or physical therapy. For (2) 11 fall screening tools were identified, but none were feasible and sufficiently accurate for ED patients. For both questions, the most frequently reported study outcome was recurrent falls, but various process and patient/clinician-centered outcomes were used. Outcome ascertainment relied on self-reported falls in 18 of 32 (56%) studies for (1) and nine of 19 (47%) studies for (2). CONCLUSION: Harmonizing definitions, research methods, and outcomes is needed for direct comparison of studies. The need to identify ED-appropriate fall risk assessment tools and role of emergency medical services (EMS) personnel persists. Multifactorial interventions, especially involving exercise, are more efficacious in reducing recurrent falls, but more studies are needed to compare appropriate bundle combinations. GEAR prioritizes five research priorities: (1) EMS role in improving fall-related outcomes, (2) identifying optimal ED fall assessment tools, (3) clarifying patient-prioritized fall interventions and outcomes, (4) standardizing uniform fall ascertainment and measured outcomes, and (5) exploring ideal intervention components.
