United States' Emergency Department Visits for Fever by Young Children 2007-2017.

ABSTRACT: INTRODUCTION:Our goal in this study was to estimate rates of emergency department (ED) visits for fever by children <2 years of age, and evaluate frequencies of testing and treatment during these visits. METHODS:We performed a cross-sectional study of ED encounters from 2007-2017 using the National Hospital Ambulatory Medical Care Survey, a cross-sectional, multi-stage probability sample survey of visits to nonfederal United States EDs. We included encounters with a visit reason of "fever" or recorded fever in the ED. We report demographics and management strategies in two groups: infants ?90 days in age; and children 91 days to <2 years old. For patients 91 days to <2 years, we compared testing and treatment strategies between general and pediatric EDs using chi-squared tests. RESULTS:Of 1.5 billion encounters over 11 years, 2.1% (95% confidence interval [CI], 1.9-2.2%) were by children <2 years old with fever. Two million encounters (95% CI, 1.7-2.4 million) were by infants ?90 days, and 28.4 million (95% CI, 25.5-31.4 million) were by children 91 days to <2 years. Among infants ?90 days, 27.6% (95% CI, 21.1-34.1%) had blood and 21.3% (95% CI, 13.6-29.1%) had urine cultures; 26.8% (95% CI, 20.9-32.7%) were given antibiotics, and 21.1% (95% CI, 15.3-26.9%) were admitted or transferred. Among patients 91 days to <2 years in age, 6.8% (95% CI, 5.8-7.8%) had blood and 7.7% (95% CI 6.1-9.4%) had urine cultures; 40.5% (95% CI, 40.5-40.5%) were given antibiotics, and 4.4% (95% CI, 3.5-5.3%) were admitted or transferred. Patients 91 days to <2 years who were evaluated in general EDs had higher rates of radiography (27.1% vs 15.2%; P<0.01) and antibiotic utilization (42.3% vs 34.2%; P<0.01), but lower rates of urine culture testing (6.4% vs 11.6%, p = 0.03), compared with patients evaluated in pediatric EDs. CONCLUSION:Approximately 180,000 patients ?90 days old and 2.6 million patients 91 days to <2 years in age with fever present to US EDs annually. Given existing guidelines, blood and urine culture performance was low for infants ?90 days old. For children 91 days to <2 years, rates of radiography and antibiotic use were higher in general EDs compared to pediatric EDs. These findings suggest opportunities to improve care among febrile young children in the ED.

Project description:OBJECTIVES:The emergency department is an important venue for initial sepsis recognition and care. We sought to determine contemporary estimates of the epidemiology of U.S. emergency department visits for sepsis. DESIGN:Analysis of data from the National Hospital Ambulatory Medical Care Survey. SETTING:U.S. emergency department visits, 2009-2011. PATIENTS:Adult (age, ? 18 yr) emergency department sepsis patients. We defined serious infection as an emergency department diagnosis of a serious infection or a triage temperature greater than 38°C or less than 36°C. We defined three emergency department sepsis classifications: 1) original emergency department sepsis-serious infection plus emergency department diagnosis of organ dysfunction, endotracheal intubation, or systolic blood pressure less than or equal to 90?mm Hg or explicit sepsis emergency department diagnoses; 2) quick Sequential Organ Failure Assessment emergency department sepsis-serious infection plus presence of at least two "quick" Sequential Organ Failure Assessment criteria (Glasgow Coma Scale ? 14, respiratory rate ? 22 breaths/min, or systolic blood pressure ? 100?mm Hg); and 3) revised emergency department sepsis-original or quick Sequential Organ Failure Assessment emergency department sepsis. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:We used survey design and weighting variables to produce national estimates of annual adult emergency department visits using updated sepsis classifications. Over 2009-2011, there were 103,257,516 annual adult emergency department visits. The estimated number of emergency department sepsis visits were as follows: 1) original emergency department sepsis 665,319 (0.64%; 95% CI, 0.57-0.73); 2) quick Sequential Organ Failure Assessment emergency department sepsis 318,832 (0.31%; 95% CI, 0.26-0.37); and 3) revised emergency department sepsis 847,868 (0.82%; 95% CI, 0.74-0.91). CONCLUSIONS:Sepsis continues to present a major burden to U.S. emergency departments, affecting up to nearly 850,000 emergency department visits annually. Updated sepsis classifications may impact national estimates of emergency department sepsis epidemiology.

Project description:Pneumonia hospitalization rates are frequently reported as a measure of pneumonia disease burden in the United States. However, a detailed understanding of pneumonia burden in all health care settings, including the emergency department (ED), is essential for measuring the full effect of this disease on the population and planning and evaluating interventions to reduce pneumonia-related morbidity. The aim of this study was to quantify pneumonia-attributable ED visits in the United States among children and adults during the 3-year period July 2006 through June 2009.Rates of pneumonia ED visits were calculated using the Nationwide Emergency Department Sample (NEDS), the largest source of U.S. ED data. Pneumonia ED visits were identified using International Classification of Diseases (ICD) codes within NEDS. A pneumonia ED visit was defined by a primary (first-listed) pneumonia discharge diagnosis or a secondary pneumonia diagnosis with an accompanying primary diagnosis of respiratory failure, shock, septicemia, a sign or symptom consistent with pneumonia, another acute respiratory infection, or an acute exacerbation of a chronic pulmonary disease. Population-based annual rates of pneumonia ED visits stratified by age group and geographic region from July 2006 through June 2009 were calculated. The percentages of pneumonia ED visits resulting in treat-and-release outpatient ED visits were also calculated within each age stratum.During the study period, 6,917,025 ED visits for pneumonia were identified, representing 2.2% of all U.S. ED visits. During the 3 study years, defined as July through June of 2006-2007, 2007-2008, and 2008-2009, pneumonia ED visit rates per 1,000 person-years were 7.4 (95% confidence interval [CI] = 7.0 to 7.8), 7.8 (95% CI = 7.3 to 8.2), and 7.6 (95% CI = 7.1 to 8.0), respectively. Annual rates were stable over the 3 years within each age group and geographic region. Overall, 39.3% of pneumonia ED visits, including 74.5% of pediatric and 28.1% of adult visits, were managed as treat-and-release outpatient visits.Pneumonia accounts for 2.2% of ED visits in the United States and results in approximately seven to eight ED visits per 1000 persons per year. A substantial proportion of pneumonia cases diagnosed in the ED are managed in treat-and-release ED outpatient visits, highlighting that enumeration of ED visit rates provides important complementary information to hospitalization rates for the assessment of pneumonia burden.

Project description:BackgroundEmergency department (ED) crowding is associated with negative health outcomes, patient dissatisfaction, and longer length of stay (LOS). The addition of advanced diagnostic imaging (ADI), namely CT, ultrasound (U/S), and MRI to ED encounter work up is a predictor of longer length of stay. Earlier and improved prediction of patients' need for advanced imaging may improve overall ED efficiency. The aim of the study was to detect the association between ADI utilization and the structured and unstructured information immediately available during ED triage, and to develop and validate models to predict utilization of ADI during an ED encounter.MethodsWe used the United States National Hospital Ambulatory Medical Care Survey data from 2009 to 2014 to examine which sociodemographic and clinical factors immediately available at ED triage were associated with the utilization of CT, U/S, MRI, and multiple ADI during a patient's ED stay. We used natural language processing (NLP) topic modeling to incorporate free-text reason for visit data available at time of ED triage in addition to other structured patient data to predict the use of ADI using multivariable logistic regression models.ResultsAmong the 139,150 adult ED visits from a national probability sample of hospitals across the U.S, 21.9% resulted in ADI use, including 16.8% who had a CT, 3.6% who had an ultrasound, 0.4% who had an MRI, and 1.2% of the population who had multiple types of ADI. The c-statistic of the predictive models was greater than or equal to 0.78 for all imaging outcomes, and the addition of text-based reason for visit information improved the accuracy of all predictive models.ConclusionsPatient information immediately available during ED triage can accurately predict the eventual use of advanced diagnostic imaging during an ED visit. Such models have the potential to be incorporated into the ED triage workflow in order to more rapidly identify patients who may require advanced imaging during their ED stay and assist with medical decision-making.

Project description:BackgroundAlcohol consumption may interfere with absorption, distribution, metabolism, and excretion of medications and increase risk of adverse drug reactions (ADR). Studies report increasing prescription medication use over time, with many U.S. drinkers using alcohol-interactive medication. This study identified trends in incidence of U.S. emergency department (ED) visits for ADR with alcohol involvement (ADR-A), compared characteristics and disposition between ADR-A visits and ADR visits without alcohol involvement (ADR-NA), and examined frequency of implicated medications in such visits for 2005 to 2011.MethodsADR visits were identified through the Drug Abuse Warning Network, a national surveillance system monitoring drug-related ED visits. Analysis accounted for sampling design effects and sampling weights. Estimates are presented for totals (ages 12+), age group, and/or sex. Trends were assessed by joinpoint log-linear regression. Differences between ADR-A and ADR-NA visits were compared using two-tailed Rao-Scott chi-square tests.ResultsFrom 2005 to 2011, incidence of ADR-A visits increased for males and females ages 21 to 34 and females ages 55+. An average of 25,303 ADR-A visits ages 12+ occurred annually. Compared with ADR-NA visits, ADR-A visits were more likely to involve males, patients ages 21 to 54, and 2+ implicated drugs. Alcohol involvement increased odds of more serious outcomes from ADR visits. Central nervous system (CNS) agents were the most common medications in ADR-A visits (59.1%), with nearly half being analgesics (mainly opioid). About 13.8% of ADR-A visits involved psychotherapeutic agents, including antidepressants. Besides CNS and psychotherapeutic agents, ADR-A visits involved a higher percentage of genitourinary-tract agents (mainly for impotence) than ADR-NA visits. Sex and age variations were observed with certain implicated medications.ConclusionsED visits for alcohol-drug interactions can be prevented by avoiding alcohol when taking alcohol-interactive medications. Our results underscore the need for healthcare professionals to routinely ask patients about alcohol consumption and warn of ADR risks before prescribing and dispensing alcohol-interactive medications.
