This report describes ambulatory care visits to hospital emergency departments (EDs) in the United States in 2004. Statistics are presented on selected hospital, patient, and visit characteristics. Selected trends in ED utilization from 1994 through 2004 are also presented.
The data presented in this report were collected in the 2004 National Hospital Ambulatory Medical Care Survey (NHAMCS), a national probability sample survey of visits to emergency and outpatient departments of non-Federal, short-stay, and general hospitals in the United States. Sample data are weighted to produce annual national estimates.
During 2004, an estimated 110.2 million visits were made to hospital EDs, about 38.2 visits per 100 persons. Visit rates have shown an increasing trend since 1994 for persons aged 22-49 years, 50-64 years, and 65 years and over. In 2004, more than 16 million patients arrived by ambulance (15.1 percent). At approximately 3 percent of visits, the patient had been seen in the ED within the last 72 hours. Abdominal pain, chest pain, fever, and back symptoms were the leading patient complaints, accounting for nearly one-fifth of all visits. Abdominal pain was the leading illness-related diagnosis at ED visits. There were an estimated 41.4 million injury-related visits or 14.4 visits per 100 persons. Diagnostic and screening services were provided at 89.9 percent of ED visits. Procedures were performed at 47.7 percent, and medications were prescribed at 78.4 percent of ED visits. Approximately 13 percent of ED visits resulted in hospital admission. On average, patients spent 3.3 hours in the ED, of which 47.4 minutes were spent waiting to see a physician.

    ABSTRACT: Introduction: Acute chest pain is an important and frequently occurring symptom in patients. Chest pain is often a sign of ischemic heart disease. Associated findings of electrocardiograph (ECG) are rather heterogeneous, and traditional cardiac biomarkers such as Creatine Kinase-MB (CK-MB) suffer from low cardiac specificity and sensitivity. In this study cost effectiveness of cardiac biomarkers single quantitative measurement was examined. Methods: The present descriptive-analytic study conducted on patients who were asked for troponin I and CK-MB. All patients who referred to Emergency unit of Tabriz Imam Reza educational-medical center during January 2012 to July the 2013 were included in study. All patients included in the study were documented in terms of age, sex, working shift of referring, main complaint of patient, symptoms in referring, ECG findings, and results of troponin I and CK-MB tests. Results: In this study, 2900 patients were studied including 1440 (49.7%) males and 1460 (50.3%) females. Mean age of patients was 62.91 (SD=14.36). Of all patients 1880 (64.8%) of patients referred during 8 a.m. to 8 p.m. and 1020 (35.2%) patients were referred during 8 p.m. to 8 a.m. The sensitivity of cardiac biomarkers’ test in diagnosing Acute Coronary Syndrome (ACS) disease was calculated as 44.8% and its specificity was 86.6%. For diagnosing Acute Myocardial Infarction (AMI), sensitivity of cardiac biomarkers’ test was 72.2% and its specificity was 86%. None of patients who were finally underwent unstable angina diagnosis showed increase in cardiac enzymes. Conclusion: In conclusion, cardiac biomarkers can be used for screening acute chest pains, also cost effectiveness of cardiac biomarkers, appropriate specificity and sensitivity can guarantee their usefulness in emergency room.

    ABSTRACT: Migraine is under diagnosed and suboptimally treated in the majority of patients, and also associated with decreased productivity in employees. The objective of this retrospective study is to assess the antimigraine medication use and associated resource utilization in employed patients. Patients with primary diagnosis of migraine or receiving antimigraine prescription drugs were identified from an employer-sponsored health insurance plan in 2010. Medical utilization and health care costs were determined for the year of 2010. Generalized linear regression was applied to evaluate the association between health care costs and the use of antimigraine medications by controlling covariates. Of 465 patients meeting the study criteria, nearly 30% that had migraine diagnosis were prescribed antimigraine medications, and 20% that had migraine diagnosis were not prescribed antimigraine medications. The remaining 50% were prescribed antimigraine medications but did not have migraine diagnosis. Patients with antimigraine medication prescriptions showed lower frequency of emergency department visits than those without antimigraine medication prescriptions. Regression models indicated an increase in migraine-related health care costs by 86% but decreases in all-cause medical costs and total health care costs by 42 and 26%, respectively, in the antimigraine medication use group after adjusting for covariates. Employed patients experienced inadequate pharmacotherapy for migraine treatment. After controlling for covariates, antimigraine prescription drug use was associated with lower total medical utilization and health care costs. Further studies should investigate patient self-reported care and needs to manage headache and develop effective intervention to improve patient quality of life and productivity.

    ABSTRACT: ABSTRACT: Abdominal pain is a common complaint among emergency department patients, making it essential to identify those with life-threatening etiologies. We report on the rare finding of atraumatic transvaginal bowel evisceration in a patient presenting to the emergency department with the primary complaint of abdominal pain. A 63-year-old female presented ambulatory to the emergency department with abdominal pain and foreign body sensation in her vagina after coughing. Physical exam demonstrated evisceration of her small bowel through her vagina. During her clinical course, she rapidly deteriorated from appearing well without abdominal tenderness to hypotensive with frank peritonitis. This case demonstrates the need to perform a thorough physical exam on all patients with abdominal pain and details the management of vaginal evisceration. This case also highlights the difficulty of appropriate triage for patients with complaints not easily assessed in triage. In an era of emergency department crowding, emergency physicians should reevaluate nursing education on triaging abdominal pain to prevent delays in caring for well-appearing patients who have underlying life-threatening illnesses.
