National study of antibiotic use in emergency department visits for pneumonia, 1993 through 2008.

ABSTRACT: The Infectious Disease Society of America (IDSA) and American Thoracic Society (ATS) developed guidelines for the management of community-acquired pneumonia (CAP); however, there are sparse data on actual rates of antibiotic use in the emergency department (ED) setting.Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS) for ED visits during 1993 through 2008 for adults with a diagnosis of pneumonia.During the study period there were an estimated 23,252,000 pneumonia visits, representing 1.8% of all ED visits. The visit rate for pneumonia during this 16-year period may have increased (p trend = 0.055). Overall, 66% of adult patients with a primary diagnosis of pneumonia had documentation of an antibiotic administered while in the ED. There was an increase in antibiotic administration for adults with pneumonia from 1993 through 2008 (49% to 80%; p trend < 0.001). Specifically, there was an increase in use of macrolides from 1993 to 2006 (20% to 30%, p trend < 0.001) and a marked increase in use of quinolones from 0% to 39% from 1993 through 2008 (p trend < 0.001). Penicillin and cephalosporin use remained stable. Use of an antibiotic consistent with 2007 IDSA/ATS guidelines increased from 22% (95% confidence interval [CI] = 16% to 27%) of cases in 1993-1994 to 68% (95% CI = 63% to 73%) of cases in 2007-2008 (p trend < 0.001).ED visit rates for pneumonia increased slightly from 1993 through 2008. Although antibiotic administration in the ED has increased for adults with CAP, guideline-concordant antibiotics may not be consistently administered.

Project description:BackgroundDetailed, nationally representative data describing high-risk populations and circumstances involved in antibiotic adverse events (AEs) can inform approaches to prevention.ObjectiveDescribe US burden, rates, and characteristics of emergency department (ED) visits by adults for antibiotic AEs.DesignNationally representative, public health surveillance of adverse drug events (National Electronic Injury Surveillance System-Cooperative Adverse Drug Event Surveillance [NEISS-CADES]) and a nationally projected database of dispensed prescriptions (QuintilesIMS), 2011-2015.PatientsAntibiotic-treated adults (≥ 20 years) seeking ED care.Main measuresEstimated annual numbers and rates of ED visits for antibiotic AEs among outpatients treated with systemically administered antibiotics.Key resultsBased on 10,225 cases, US adults aged ≥ 20 years made an estimated 145,490 (95% confidence interval, 115,279-175,701) ED visits for antibiotic AEs each year in 2011-2015. Antibiotics were implicated in 13.7% (12.3-15.2%) of all estimated adult ED visits for adverse drug events. Most (56.6%; 54.8-58.4%) antibiotic AE visits involved adults aged < 50 years, and 71.8% (70.4-73.1%) involved females. Accounting for prescriptions dispensed from retail and long-term care pharmacies, adults aged 20-34 years had twice the estimated rate of ED visits for oral antibiotic AEs compared with those aged ≥ 65 years (9.7 [7.6-11.8] versus 4.6 [3.6-5.7] visits per 10,000 dispensed prescriptions, respectively). Allergic reactions accounted for three quarters (74.3%; 70.0-78.6%) of estimated ED visits for antibiotic AEs. The three most frequently implicated antibiotic classes in ED visits for antibiotic AEs were oral sulfonamides (23.2%; 20.6-25.8%), penicillins (20.8%; 19.3-22.4%), and quinolones (15.7%; 14.2-17.1%). Per-prescription rates declined with increasing age group.ConclusionsAntibiotics are a common cause of ED visits by adults for adverse drug events and represent an important safety issue. Quantifying risks of AEs from specific antibiotics for specific patient populations, such as younger adults, provides additional information to help clinicians assess risks versus benefits when making the decision to prescribe or not prescribe an antibiotic. AE rates may also facilitate communication with patients about antibiotic risks.

Project description:BackgroundAcute healthcare utilization attributed to alcohol use disorders (AUD) and other substance use disorders (SUD) is rising.ObjectiveTo describe the prevalence and characteristics of emergency department (ED) visits and hospitalizations made by adults with AUD or SUD.Design, setting, and participantsObservational study with retrospective analysis of the National Hospital Ambulatory Medical Care Survey (2014 to 2018), a nationally representative survey of acute care visits with information on the presence of AUD or SUD abstracted from the medical chart.Main measuresOutcome measured as the presence of AUD or SUD.Key resultsFrom 2014 to 2018, the annual average prevalence of AUD or SUD was 9.4% of ED visits (9.3 million visits) and 11.9% hospitalizations (1.4 million hospitalizations). Both estimates increased over time (30% and 57% relative increase for ED visits and hospitalizations, respectively, from 2014 to 2018). ED visits and hospitalizations from individuals with AUD or SUD, compared to individuals with neither AUD nor SUD, had higher percentages of Medicaid insurance (ED visits: AUD: 33.1%, SUD: 35.0%, neither: 24.4%; hospitalizations: AUD: 30.7%, SUD: 36.3%, neither: 14.8%); homelessness (ED visits: AUD: 6.2%, SUD 4.4%, neither 0.4%; hospitalizations: AUD: 5.9%, SUD 7.3%, neither: 0.4%); coexisting depression (ED visits: AUD: 26.3%, SUD 24.7%, neither 10.5%; hospitalizations: AUD: 33.5%, SUD 35.3%, neither: 13.9%); and injury/trauma (ED visits: AUD: 51.3%, SUD 36.3%, neither: 26.4%; hospitalizations: AUD: 31.8%, SUD: 23.8%, neither: 15.0%).ConclusionsIn this nationally representative study, 1 in 11 ED visits and 1 in 9 hospitalizations were made by adults with AUD or SUD, and both increased over time. These estimates are higher or similar than previous national estimates using claims data. This highlights the importance of identifying opportunities to address AUD and SUD in acute care settings in tandem with other medical concerns, particularly among visits presenting with injury, trauma, or coexisting depression.

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: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:Background and objectivesIn 2011, there were approximately 131 million visits to an emergency department in the United States. Emergency department visits have increased over time, far outpacing growth of the general population. There is a paucity of data evaluating emergency department visits among kidney transplant recipients. We sought to evaluate the incidence and risk factors for emergency department visits after initial hospital discharge after transplantation in the United States.Design, setting, participants, & measurementsWe identified 10,533 kidney transplant recipients from California, New York, and Florida between 2009 and 2012 using the State Inpatient and Emergency Department Databases included in the Healthcare Cost and Utilization Project. We used multivariable Poisson and Cox proportional hazard models to evaluate adjusted incidence rates and time to emergency department visits after transplantation.ResultsThere were 17,575 emergency department visits over 13,845 follow-up years (overall rate =126.9/100 patient-years; 95% confidence interval, 125.1 to 128.8). The cumulative incidences of emergency department visits at 1, 12, and 24 months were 12%, 40%, and 57%, respectively, with median time =19 months; 48% of emergency department visits led to hospital admission. Risk factors for higher emergency department rates included younger age, women, black and Hispanic race/ethnicity, public insurance, depression, diabetes, peripheral vascular disease, and emergency department use before transplant. There was wide variation in emergency department visits by individual transplant center (10th percentile =70.0/100 patient-years; median =124.6/100 patient-years; and 90th percentile =187.4/100 patient-years).ConclusionsThe majority of kidney transplant recipients will visit an emergency department in the first 2 years post-transplantation, with significant variation by patient characteristics and individual centers. As such, coordination of care through the emergency department is a critical component of post-transplant management, and specific acumen of transplant-related care is needed among emergency department providers. Additional research assessing best processes of care for post-transplant management and health care expenditures and outcomes associated with emergency department visits for transplant recipients are warranted.
