Temporal trends in emergency department visits for bronchiolitis in the United States, 2006 to 2010.

ABSTRACT: To examine temporal trends in emergency departments (EDs) visits for bronchiolitis among US children between 2006 and 2010.Serial, cross-sectional analysis of the Nationwide Emergency Department Sample, a nationally representative sample of ED patients. We used International Classification of Diseases, Ninth Revision, Clinical Modification code 466.1 to identify children <2 years of age with bronchiolitis. Primary outcome measures were rate of bronchiolitis ED visits, hospital admission rate and ED charges.Between 2006 and 2010, weighted national discharge data included 1,435,110 ED visits with bronchiolitis. There was a modest increase in the rate of bronchiolitis ED visits, from 35.6 to 36.3 per 1000 person-years (2% increase; Ptrend = 0.008), due to increases in the ED visit rate among children from 12 months to 23 months (24% increase;Ptrend < 0.001). By contrast, there was a significant decline in the ED visit rate among infants (4% decrease; Ptrend < 0.001). Although unadjusted admission rate did not change between 2006 and 2010 (26% in both years), admission rate declined significantly after adjusting for potential patient- and ED-level confounders (adjusted odds ratio for comparison of 2010 with 2006, 0.84; 95% confidence interval: 0.76-0.93; P < 0.001). Nationwide ED charges for bronchiolitis increased from $337 million to $389 million (16% increase; Ptrend < 0.001), adjusted for inflation. This increase was driven by a rise in geometric mean of ED charges per case from $887 to $1059 (19% increase; Ptrend < 0.001).Between 2006 and 2010, we found a divergent temporal trend in the rate of bronchiolitis ED visits by age group. Despite a significant increase in associated ED charges, ED-associated hospital admission rates for bronchiolitis significantly decreased over this same period.

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:ObjectiveThe aim of this study was to examine differences between general and pediatric emergency departments (PEDs) in adherence to the American Academy of Pediatrics bronchiolitis management guidelines.MethodsWe conducted a nationally representative study of ED visits by infants younger than 24 months with bronchiolitis from 2002 to 2011 using the National Hospital Ambulatory Medical Care Survey. Diagnostic testing (complete blood counts, radiographs) and medication use (albuterol, corticosteroids, antibiotics and intravenous fluids) in general emergency departments (GEDs) were compared with those in PEDs before and after 2006 American Academy of Pediatrics guideline publication. Weighted percentages were compared, and logistic regression evaluated the association between ED type and resource use.ResultsOf more than 2.5 million ED visits for bronchiolitis from 2002 to 2011, 77.3% occurred in GEDs. General emergency departments were more likely to use radiography (62.7% vs 42.1%; adjusted odds ratio [aOR], 2.4; 95% confidence interval [CI], 1.4-4.1), antibiotics (41.3% vs 18.8%; aOR, 2.8; 95% CI, 1.5-5.2), and corticosteroids (24.3% vs 12.5%; aOR, 2.1; 95% CI, 1.0-4.5) compared with PEDs. Compared with preguideline, after guideline publication PEDs had a greater decrease in radiography use (-19.7%; 95% CI, -39.3% to -0.03%) compared with GEDs (-12.2%; 95% CI, -22.3% to -2.1%), and PEDs showed a significant decline in corticosteroid use (-12.4%; 95% CI, -22.1% to -2.8%), whereas GEDs showed no significant decline (-4.6%; 95% CI, -13.5% to 4.3%).ConclusionsThe majority of ED visits for bronchiolitis in the United States occurred in GEDs, yet GEDs had increased use of radiography, corticosteroids, and antibiotics and did not show substantial declines with national guideline publication. Given that national guidelines discourage the use of such tests and treatments in the management of bronchiolitis, efforts are required to decrease ED use of these resources in infants with bronchiolitis, particularly in GEDs.

Project description:IntroductionOur 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.MethodsWe 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.ResultsOf 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.ConclusionApproximately 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: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.
