Association Between Emergency Medical Services Intervention Volume and Out-of-Hospital Cardiac Arrest Survival: A Propensity Score Matching Analysis.
Out of hospital cardiac arrest (OHCA) survival rates are very low. An association between institutional OHCA case volume and patient outcomes has been documented. However, whether this applies to prehospital emergency medicine services (EMS) is unknown. ⋯ 2,014 adult patients (69% male, median age 68 [57-79] years) were analyzed, 50.5% (n = 1,017) were managed by low-volume MICU and 49.5% (n = 997) by high-volume MICU. Survival on day 30 was 3.6% in the low-volume group compared to 5.1% in the high-volume group. There was no significant association between MICU volume of intervention and survival on day 30 (OR = 0.92, 95%CI [0.55;1.53]), prehospital ROSC (OR = 1.01[0.78;1.3]), ROSC at hospital admission (OR = 0.92 [0.69;1.21]), or favorable neurologic prognosis on day 30 (OR = 0.92 [0.53;1.62]).

Delayed intracranial hemorrhage (ICH) after head injury in older patients taking anticoagulants has been reported to be as high as 7.2%. Other studies suggest much lower rates. Its incidence and clinical management are controversial, with some recommending observation and repeat head imaging at 24 h. ⋯ The incidence of delayed ICH is very low in older ED head trauma patients on prescribed pre-injury anticoagulants. Our data have important clinical implications for the management of blunt head trauma among older ED patients on anticoagulants.

A paucity of literature exists dedicated to the identification of anoxic brain injury in patients that survive non-fatal intimate partner strangulation (NF-IPS). While some individuals report experiencing symptoms of brain hypoxia followed by a loss of consciousness, other individuals report symptoms of brain hypoxia prior to amnesia, rendering some unable to recall loss of consciousness (LOC). ⋯ Within our sample, 49% of patients with amnesia did not recall losing consciousness, demonstrating that LOC is an imperfect measure of anoxia for patients following NF-IPS. Healthcare providers examining NF-IPS patients should inquire about additional symptoms of hypoxia and amnesia, which can be captured on the SHASTA tool.

Emergency departments (EDs) are often patients' first point of contact with the health care system. Race, ethnicity, and language all influence factors leading up to ED visits and patient experiences within the ED. There is limited evidence showing how race, ethnicity, and language interact to shape ED experiences, particularly during the COVID-19 pandemic when EDs were extremely strained. ⋯ Findings suggest multiple mechanisms influence hospital admissions for patients who are racially and ethnically minoritized and speak Spanish. Providers may have admitted patients as a precaution rather than because of more advanced illness. Evaluating race, ethnicity, and language concurrently can reveal how intersectional factors shape patient experiences in the ED.

Quantitative and qualitative human chorionic gonadotropin (hCG) tests are obtained in the emergency department (ED) to determine if a female of child-bearing age is pregnant. A positive hCG result is commonly assumed to indicate an intrauterine or other form of pregnancy. However, elevated hCG levels can also result from various other conditions, such as ovarian tumors, pituitary tumors, and thyroid disorders. Intracranial germ cell tumors, rare central nervous system tumors capable of secreting hCG, primarily affect adolescent and young adult females. ⋯ A 16-year-old female student without significant past medical history presented to our ED with a complaint of intermittent bilateral frontal headache for two days. Last menstrual period started two days prior to presentation. The headache was associated with phonophobia, photophobia, nausea, and vomiting. Serum quantitative hCG was elevated. She denied history of sexual activity or sexual assault. Transabdominal ultrasound was negative for intrauterine pregnancy. Obstetrics and gynecology as well as pediatric oncology were consulted. Subsequent investigations, including brain imaging, revealed a 3.5 cm mass in the right caudate nucleus and corpus callosum. The patient was diagnosed with an intracranial nongerminomatous germ cell tumor, necessitating hospitalization and prompt initiation of chemotherapy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: An elevated quantitative hCG is not always indicative of pregnancy, especially in a young patient without sexual history. In the case of a nonrevealing transabdominal ultrasound, obstetrics and gynecology should be consulted for discussion of further testing and imaging. Emergency physicians should include malignancy high on their differential since prompt initiation of chemotherapy, evaluation by surgical services, and family planning will be required.
