Existing evidence suggests a link between ABO blood type and severe outcomes in coronavirus disease 2019 (COVID‐19). We aimed to assess the relationship between blood type and severe outcomes across variant strains throughout the pandemic. This was a multicenter retrospective observational cohort analysis from a large health system in southeastern Michigan using electronic medical records to evaluate emergency encounters, hospitalization, and severe outcomes in COVID‐19 based on ABO blood type. Consecutive adult patients presenting to the emergency department with a primary diagnosis of COVID‐19 (U07.1) from March 1, 2020 through December 31, 2022 were assessed. Patients who presented during three distinct time intervals that coincided with Alpha, Delta, and Omicron variant predominance were included in the analysis. Exclusions included no record of ABO blood type, positive PCR COVID‐19 test within the preceding 28 days, and if transferred from out of the health system. Severe outcomes were inclusive of intensive care unit admission, mechanical ventilation, or death, which, as a composite, represented our primary outcome. Secondary outcomes were hospital admission and length of stay. A logistic regression model was employed to test the association between ABO blood type and severe outcome, adjusting for age, sex, race, vaccination status, Elixhauser comorbidity indices, and the dominant variant time period in which the encounter occurred. Of the 33,796 COVID‐19 encounters, 9416 met inclusion criteria; 4071 (43.2%) were type O, 3417 (36.3%) were type A, 459 (4.9%) were type AB, and 1469 (15.6%) were type B blood. Note that 66.4% of the cohort was female (p = 0.18). The proportion of composite severe disease among the four blood types was similar and ranged between 8.6% and 8.9% (p = 0.98). Note that 53.0% of type A blood patients required hospital admission, compared to 51.9%, 50.4%, and 48.1% of type AB, B, and O blood, respectively (p < 0.001). Compared to patients with O blood type (43.2%), non‐O blood type (58.8%; composite of A, AB, and B) exhibited no statistically significant difference in the proportion of composite severe disease (8.8% vs. 8.7%; p = 0.81) Multivariable regression analyses exhibited no significant difference regarding the presence of severe outcomes among the four blood types or O versus non‐O blood types during T1, T2, and T3. ABO blood type was not associated with COVID‐19 severe outcomes across the Delta, Alpha, and Omicron dominant COVID waves across a large health system in southeastern Michigan. Further research is needed to better understand if ABO blood type is a risk factor for severe disease among evolving COVID‐19 variants and other viral upper respiratory infections.

Intranasal medications have been proposed as adjuncts to out‐of‐hospital cardiac arrest (OHCA) care. We sought to quantify the effects of intranasal medication administration (INMA) in OHCA workflows. We conducted separate randomized OHCA simulation trials with lay rescuers (LRs) and first responders (FRs). Participants were randomized to groups performing hands‐only cardiopulmonary resuscitation (CPR)/automated external defibrillator with or without INMA during the second analysis phase. Time to compression following the second shock (CPR2) was the primary outcome and compression quality (chest compression rate (CCR) and fraction (CCF)) was the secondary outcome. We fit linear regression models adjusted for CPR training in the LR group and service years in the FR group. Among LRs, INMA was associated with a significant increase in CPR2 (mean diff. 44.1 s, 95% CI: 14.9, 73.3), which persisted after adjustment (p = 0.005). We observed a significant decrease in CCR (INMA 95.1 compressions per min (cpm) vs control 104.2 cpm, mean diff. −9.1 cpm, 95% CI −16.6, −1.6) and CCF (INMA 62.4% vs control 69.8%, mean diff. −7.5%, 95% CI −12.0, −2.9). Among FRs, we found no significant CPR2 delays (mean diff. −2.1 s, 95% CI −15.9, 11.7), which persisted after adjustment (p = 0.704), or difference in quality (CCR INMA 115.5 cpm vs control 120.8 cpm, mean diff. −5.3 cpm, 95% CI −12.6, 2.0; CCF INMA 79.6% vs control 81.2% mean diff. −1.6%, 95% CI −7.4, 4.3%) INMA in LR resuscitation was associated with diminished resuscitation performance. INMA by FR did not impede key times or quality.

“Academic surgeon” describes a member of a medical school department of surgery, but this term does not fully define the important role of such physician-scientists in advancing surgical science through translational research and innovation. The curriculum vitae and self-descriptive vignettes of the records of achievement of seven surgeons possessing documented records of academic leadership, innovation, and dissemination of knowledge were reviewed. Out analysis yielded seven attributes of the archetypal academic surgeon: 1) identifies complex clinical problems ignored or thought unsolvable by others, 2) becomes an expert, 3) innovates to advance treatment, 4) observes outcomes to further improve and innovate, 5) disseminates knowledge and expertise, 6) asks important questions to further improve care, and 7) trains the next generation of surgeons and scientists. Although alternative pathways to innovation and academic contribution also exist, the academic surgeon typically devotes years of careful observation, analysis, and iterative investigation to identify and solve challenging or unexplored clinical problems, ideally leverages resources available in academic medical centers to support these endeavors.

The empiric usage of systemic thrombolysis for refractory out of hospital cardiac arrest (OHCA) is considered for pulmonary embolism (PE), but not for undifferentiated cardiac etiology [1, 2]. We report a case of successful resuscitation after protracted OHCA with suspected non-PE cardiac etiology, with favorable neurological outcome after empiric administration of systemic thrombolysis. A 47-year-old male presented to the emergency department (ED) after a witnessed OHCA with no bystander cardiopulmonary resuscitation (CPR). His initial rhythm was ventricular fibrillation (VF) which had degenerated into pulseless electrical activity (PEA) by ED arrival. Fifty-seven minutes into his arrest, we gave systemic thrombolysis which obtained return of spontaneous circulation (ROSC). He was transferred to the coronary care unit (CCU) and underwent therapeutic hypothermia. On hospital day (HD) 4 he began following commands and was extubated on HD 5. Subsequent percutaneous coronary intervention (PCI) revealed non-obstructive stenosis in distal LAD. He was discharged home directly from the hospital, with one-month cerebral performance category (CPC) score of one. He was back to work three months post-arrest. Emergency physicians (EP) should be aware of this topic since we are front-line health care professionals for OHCA. Thrombolytics have the advantage of being widely available in ED and therefore offer an option on a case-by-case basis when intra-arrest PCI and ECPR are not available. This case report adds to the existing literature on systemic thrombolysis as salvage therapy for cardiac arrest from an undifferentiated cardiac etiology. The time is now for this treatment to be reevaluated.

Operative hysteroscopy intravascular absorption syndrome is an iatrogenic syndrome caused by absorption of hypo-osmolar distension medium during hysteroscopy, which can lead to rapid hyponatremia with resulting cerebral and pulmonary edema. We present a case of a 47-year-old female who underwent hysteroscopic myomectomy at an outpatient ambulatory surgical center who was brought to the emergency department with dyspnea, hypoxia, and altered mental status. Workup showed hyponatremia with cerebral edema on computed tomography of the head and pulmonary edema on chest radiograph. The patient improved after resuscitation with intravenous saline and supplemental oxygen, and she was discharged home the next day.

The objective of the study is to determine if tamsulosin initiated in the emergency department (ED) decreases the time to ureteral stone passage at 1 week or time to pain resolution, compared to placebo. We performed a prospective, randomized, double-blinded, placebo-controlled trial of tamsulosin vs placebo in ED patients with ureterolithiasis on computed tomography. Patients were identified and enrolled between April 2007 and February 2009 and were randomized to either 0.4 mg of tamsulosin or placebo for 1 week. We contacted participants using a telephone survey on post-ED visit days 1, 2, 3, and 7. The primary outcome was time to stone passage, with secondary outcomes being maximum pain score and amount of pain medication required. Of the 127 patients enrolled during this study, 15 were lost to follow-up, and 12 required surgical interventions before the 7-day mark, leaving 100 patients for analysis. Of the 100 patients, 53 received tamsulosin and 47 received placebo. There was no difference between groups in percentage of male, mean age, initial serum creatinine, average stone size, stone location, and history of prior stone. The probability that the patient did not pass a stone at 7 days was not different between tamsulosin and placebo, 62.1% (95% confidence interval, 49.1%-75.1%) vs 54.4% (95% confidence interval, 40.3%-68.6%; P = .58). There was no significant difference in the high pain score (P = .12) or hydrocodone/acetaminophen intake (P = .76) between treatment groups at any of the time points. This study reveals no difference in the proportion of stone passage or high pain score and pain medication utilization at 7 days between tamsulosin and placebo.

Screening for acute myocardial infarction (AMI) in patients with ventricular pacemakers (VP) is a diagnostic challenge. We report a case where application of the Modified Sgarbossa criteria (mSC) would have immediately identified AMI in a patient with a VP and merited strong advocacy for emergent cardiac catheterization. A 94-year-old male with VP presented to the emergency department (ED) after he had burning sensation in his chest. Initial ECG demonstrated >5 mm of discordant ST elevation in leads III and aVF which gave him 2 points per original Sgarbossa Criteria (oSC) and not meeting criteria for activation for cardiac catheterization. An ECG at three and a half hours after arrival demonstrated a dynamic change with new V2 concordant depression. At this point, the concordant depression (3 points) and excessive discordance (2 points) gave him a total of 5 points, which then met the oSC for activation of cardiac catheterization (≥ 3 points). Troponin I value (ng/mL) at 0/2/4 h after ED arrival are 0.02, 0.08 and 4.33 respectively. Pain never recurred after single nitroglycerine (NTG) tablet upon arrival. He was urgently taken for catheterization and had acute right coronary artery (RCA) culprit lesion and discharged on hospital day 4. This case report highlighted the benefits of applying mSC to patients with VP, which to authors knowledge remains unvalidated. A significant benefit of mSC is that they are unweighted, thus any positive criteria is suggestive of AMI. While the first EKG yielded an oSC score <3, applying the unweighted mSC to the EKG revealed ≤−0.25 ST/S ratio discordant changes in leads III, aVF, I and aVL would have merited strong advocacy for emergent cardiac catherization.

We present a case of bilateral posterior native hip dislocations after a fall from standing. This exceedingly rare diagnosis is classically associated with younger patients whose bones are strong enough to dislocate rather than fracture in the setting of a high-momentum collision. We present an unusual case of an 88-year-old male with native hips who sustained a low-energy collision after falling from standing and was found to have bilateral posterior hip dislocations without associated pelvis or femur fractures.

The management of cardiac arrest patients receiving cardiopulmonary resuscitation (CPR) is an essential aspect of emergency medicine (EM) training. At our institution, we have a 1-month Resuscitation Rotation designed to augment resident training in managing critical patients. The objective of this study is to compare 30-day mortality between cardiac arrest patients with resuscitation resident (RR) involvement versus patients without. Our secondary outcome is to determine if RR involvement altered rates of initiating targeted temperature management (TTM). This study was conducted at a single site tertiary care Level-1 trauma center with an Emergency Department (ED) census of nearly 130,000 visits per year. Data was collected from 01/01/2015 to 01/01/2018 using electronic medical records via query. Patients admitted with cardiac arrest were separated into two groups, one with RR involvement and one without. Initial rhythm of ventricular fibrillation/tachycardia (VFIB/VTACH), 30-day mortality, history of coronary artery disease (CAD), and initiation of TTM were compared. Statistical analysis was performed. Out of 885 patient encounters, 91 (10.28%) had RR participation. There was no statistical difference in 30-day mortality between patients with RR involvement compared to those without (71.42% vs 66.36%; P = 0.3613). However, TTM was initiated more in the RR group (20.70% vs 8.86%; P = 0.0025). Patients who received TTM also had a lower 30-day mortality compared to those without TTM (52.94% vs 70.87%; P = 0.0020). Patients who were older and had no history of CAD were also noted to have a statistically significant higher 30-day mortality. All other variables were not statistically significant. Resuscitation resident involvement with the care of cardiac arrest patients had no impact in 30-day mortality. However, the involvement of RR was associated with a statistically significant increase in the initiation of TTM. One limitation is that RR participated in 10.28% of the cases analyzed herein, thus the two arms are unbalanced in size. Future work may investigate if the increase in TTM in the RR involved cases may portend improved rates of neurologically intact survival or more rapid achievement of goal temperatures. •Patients' 30-day mortality was no different with Resuscitation Resident involvement.•Resuscitation Resident involvement was associated with increased provision of TTM.•Patients who received TTM had a lower 30-day mortality compared to those without.•The resuscitation rotation is curriculum demonstrating clinical benefit to patients.
