The Association of Preinfection Daily Oral Anticoagulation Use and All-Cause in Hospital Mortality From Novel Coronavirus 2019 at 21 Days: A Retrospective Cohort Study.

OBJECTIVES: Practices regarding anticoagulation use in coronavirus disease 2019 focus primarily on its efficacy in the critically ill without a clear understanding of when to begin anticoagulation. We sought to understand the association of preinfection daily oral anticoagulation use and the short-term mortality of patients hospitalized with coronavirus disease 2019. DESIGN: Retrospective chart review. SETTING: Large health system with high coronavirus disease 2019 prevalence. PATIENTS: Patients 60 years or older admitted to the hospital with positive coronavirus disease 2019 polymerase chain reaction test. INTERVENTIONS: We compared both those on warfarin and those on a direct oral anticoagulant prior to admission and throughout disease course with those who were never exposed to an oral anticoagulant. RESULTS: Our primary outcome was inhospital mortality at 21 days from the first coronavirus disease 2019 test ordered. Patients in the direct oral anticoagulant group (n = 104) were found to have significantly lower 21-day all-cause in hospital mortality than patients in the control group (n = 894) both prior to adjustment (14.4% vs 23.8%; odds ratio, 0.57 [0.29-0.92]; p = 0.03) and after controlling for age, gender, and comorbidities (odds ratio, 0.44 [0.20-0.90]; p = 0.033). Patients on warfarin (n = 28) were found to have an elevated unadjusted mortality rate of 32% versus 23.8% in the control group (odds ratio, 1.51 [0.64-3.31]; p = 0.31). After adjustment, a reduction in mortality was observed but not found to be statistically significant (odds ratio, 0.29 [0.02-1.62]; p = 0.24). There was no statistical difference noted in the number of bleeding events in each group. CONCLUSIONS: In this retrospective cohort study evaluating oral anticoagulant use among patients with coronavirus disease 2019, we found that patients who are on daily oral anticoagulation at the time of infection and throughout their disease course had significantly lower risk of all-cause mortality at 21 days. Validation of these findings should be performed on population-based levels. While research regarding anticoagulation algorithms is ongoing, we believe these results support future randomized control trials to understand the efficacy and risk of the use of early oral anticoagulation.

Development of a statewide hospital plan for radiologic emergencies.

Although general guidelines have been developed for triage of victims in the field and for hospitals to plan for a radiologic event, specific information for clinicians and administrators is not available for guidance in efficient management of radiation victims during their early encounter in the hospital. A consensus document was developed by staff members of four Connecticut hospitals, two institutions of higher learning, and the State of Connecticut Department of Environmental Protection and Office of Emergency Preparedness, with assistance of the American Society for Therapeutic Radiology and Oncology. The objective was to write a practical manual for clinicians (including radiation oncologists, emergency room physicians, and nursing staff), hospital administrators, radiation safety officers, and other individuals knowledgeable in radiation monitoring that would be useful for evaluation and management of radiation injury. The rationale for and process by which the radiation response plan was developed and implemented in the State of Connecticut are reviewed. Hospital admission pathways are described, based on classification of victims as exposed, contaminated, and/or physically injured. This manual will be of value to those involved in planning the health care response to a radiologic event.

Late postpartum eclampsia as an obstetric complication seen in the ED.

Preeclampsia is a complication of pregnancy associated with hypertension and proteinuria. Preeclampsia may be associated with grand mal seizures and is termed eclampsia. Historically, eclampsia occurring more than 48 hours after delivery, known as late postpartum eclampsia, was thought to be uncommon; however, recent evidence suggests that its incidence is increasing. In addition, the presentation of late postpartum preeclampsia-eclampsia may differ from that occurring during the pregnancy. This contributes to difficulty in diagnosing late postpartum preeclampsia-eclampsia in an emergency department setting. We report 2 cases of late postpartum eclampsia presenting 8 days after delivery, which highlight the unique features of this disorder and discuss some of the difficulties in managing these patients. Greater awareness and knowledge of this disorder by ED physicians should improve outcomes in these potentially life-threatening cases.

Effectiveness of a multidisciplinary quality improvement initiative in reducing door-to-balloon times in primary angioplasty.

Primary angioplasty (PA) for acute myocardial infarction (AMI) has emerged as the standard of care in hospitals with cardiac interventional facilities. The benefits from the PA are time dependent, but recent data raise concerns regarding the timeliness of delivery of care in AMI and the level of benefit achieved by current standards. We assessed the effectiveness of an extensive multidisciplinary quality improvement initiative in reducing door-to-balloon (DTB) times in PA. The PA process was divided into six separate time periods, which were assessed individually. Subsequent quality initiatives resulted in a dramatic reduction in the mean DTB time (141.3 minutes preintervention compared to 95.1 minutes postintervention; P < 0.001).

Value of a single troponin T at the time of presentation as compared to serial CK-MB determinations in patients with suspected myocardial ischemia.

BACKGROUND: Prior studies with cardiac markers have focused predominantly on subjects presenting to the emergency department with chest pain or unstable angina, and have relied on serial markers for the diagnosis of acute myocardial infarction. We evaluated the diagnostic utility of a single cardiac troponin T (cTnT) determination at the time of presentation as compared to serial creatine kinase (CK) MB determinations in a broad spectrum of patients with suspected myocardial ischemia. METHODS: A total of 267 consecutive patients presenting to the emergency department with suspected myocardial ischemia had a single, blinded cTnT determination drawn at the time of presentation to the emergency department in addition to routine serial electrocardiographic and CK-MB determinations. RESULTS: The specificity (93.7% vs. 87.1%; p<0.05) and positive predictive value (80.0% vs. 69.4%; p<0.05) of a single cTnT determination were superior to that of serial CK-MB determinations without compromising sensitivity. Forty-six percent of patients with confirmed myocardial infarction and an abnormal cTnT at presentation had a normal initial CK-MB determination. Conversely, 20% of patients without acute coronary syndromes had an abnormal CK-MB determination in the setting of a normal cTnT. The initial cTnT was abnormal in all patients with confirmed myocardial infarction and a symptom duration of at least 3.5 h. CONCLUSIONS: In a heterogeneous population of patients with suspected myocardial ischemia, the initial cTnT determination drawn at the time of presentation is a powerful diagnostic tool that, when used in context with symptom duration, allows for more rapid and accurate triage of patients than serial CK-MB determinations.
