Emergency care of asthma.

Children with asthma frequently receive care in the emergency department (ED). The factors associated with presentation to the ED are complex and must be considered when developing a treatment plan and disposition. The diagnosis and assessment must be rapid and focused, and treatment must be initiated promptly. Objective measures should be used where possible to assess the response to therapy and determine readiness for discharge. This Article reviews the essential components of diagnosis, assessment, and treatment of pediatric asthma in the ED, and it reviews the key elements of discharge planning.

A comparison of New York City playground hazards in high- and low-income areas.

OBJECTIVE: To compare playground hazards in high- and low-income neighborhoods. DESIGN: Forty-five playgrounds were randomly selected from the 9 New York City community districts that met our study criteria and were divided into high-and low-income groups based on comparison to the median of the median incomes ($24452 per year) of the 9 districts. Playgrounds are maintained by the City of New York Parks and Recreation Department and were assessed by one of us (S.A.S.) using a standardized on-site survey based on the US Consumer Product Safety Commission's guidelines for public playground safety. MAIN OUTCOME MEASURES: Total hazards per play area were subdivided into 3 categories: park design hazards, equipment maintenance hazards, and equipment hazards relating to fall injuries. A play area was defined as an individual set of equipment. RESULTS: Twenty-five (56%) of the parks were located in low-median-income districts and contained 98 (53%) of the total play areas. High- and low-income playgrounds did not differ significantly in the amount or type of equipment, mean fall injury hazards per play area, or mean park design hazards per play area. Low-income districts had a significantly higher mean total hazards per play area (6.1 vs. 4.2; P = .02) and mean equipment maintenance hazards per play area (2.1 vs. 1.0; P = .02). CONCLUSION: Significantly more hazards per play area were identified in the low-income group compared with the high-income group.

Pediatric asthma care in the emergency department: measuring the quality of history-taking and discharge planning.

The National Asthma Education and Prevention Program NAEPP Guidelines include recommendations for history-taking and discharge planning during an asthma visit, but there are no tools to measure performance. The objectives of this study were to define and operationalize key elements of history-taking and discharge planning, to develop a tool for measuring these elements, and to evaluate the quality of history-taking and discharge planning in the emergency department (ED) during visits for asthma using the new tool. Expert opinion and extensive literature review were used to develop a 13-item checklist containing items that should be documented during history-taking and provided during discharge planning for an ED visit for an acute asthma exacerbation by children. A convenience sample of 90 pediatric emergency medicine physicians and allergists rated each item in the checklist. The checklist was used to score audiotapes of asthma visits in the ED. Subjects were 154 parents of asthmatic children aged 4-9 years seeking care in nine inner-city EDs affiliated with asthma centers participating in the National Cooperative Inner-City Asthma Study and the physician/providers who delivered care. Seven of the 13 items on the checklist were rated as required to be performed by more than 90% of the allergist/pediatric emergency medicine physicians. Only 10% of the 154 visits included all seven of the highly rated items, whereas 19% of the visits included three or fewer. Only 7 of the 13 items (54%) were performed in more than 50% of the visits, and 4 items were performed in fewer than 25% of visits. Based on expert ratings, the checklist for measuring elements of history-taking and discharge planning during asthma visits appears to have considerable face validity. In the visits studied, the overall performance of these elements was low. Interventions to improve performance on the checklist might lead to improved care for children with asthma who frequent the ED.

Reported difficulties in access to quality care for children with asthma in the inner city.

OBJECTIVE: To characterize perceived access and barriers to quality health care for asthma among the caregivers of children in the inner city. DESIGN: Multicenter, cross-sectional survey. SETTING: Eight sites in 7 major metropolitan US inner cities. PARTICIPANTS: A systematic sample of children with asthma, aged 4 to 9 years, and their caregivers who resided in census tracts in which at least 30% of the households were below the 1990 federal poverty guidelines, recruited from 25 primary care clinics and 13 emergency departments (EDs) from November 1, 1992, through October 31, 1993. RESULTS: Of the 1528 children enrolled, 1376 had physician-diagnosed asthma and form the basis of this report. This group was further divided into 284 children (20.6%) who met all recruitment criteria for severe asthma and 207 (15.0%) with mild asthma who met none. Of parents in the total sample, 95.6% reported a usual place for short-term asthma care for their child; 75.4% used the ED. Children with severe asthma were significantly more likely to use the ED than those with mild asthma (84.3% vs 63.0%; P<.01). A usual place for follow-up asthma care was reported by 96.7% of subjects. There were no differences in access or type of facility used by asthma severity. More than half the study group reported difficulty in accessing care for acute asthma attacks and for follow-up care with no differences by asthma severity. Among those with severe asthma, 47.5% used inhaled steroids or cromolyn, 52.8% used a spacer device if they had been prescribed a metered dose inhaler, and 21.2% of children older than 6 years were prescribed a peak flowmeter. Patients with mild asthma were significantly less likely to report use of all 3 items (steroids or cromolyn, 1.4%; spacer device, 15.4%; and peak flowmeter, 3.1%, respectively; P<.01). CONCLUSION: Although access to asthma care among children in US inner cities appears adequate as determined by the traditional measure of reporting a regular source of care, barriers are frequently reported, as are deficiencies in the quality of medical care.

Burden of wheezing illness among U.S. children reported by parents not to have asthma.

We examined the 12-month prevalence of asthma and wheezing among U.S. children and compared the illness-related burden of children who wheezed with and without an asthma diagnosis. Data were obtained in a cross-sectional telephone survey that tested the performance of a health interview designed to identify children with chronic health conditions. Respondents were 712 primary caretakers of 1388 children under 18 years old in a national probability sample selected by random-digit dialing. Although 51 children identified with asthma and wheezing had more episodes, sleep disturbances, and attacks that limited speech, and received more medical treatment for wheezing than 69 children with wheezing alone, the "undiagnosed" children appeared to be only somewhat less affected by their wheezing. Repeat episodes and burden experienced by children with wheezing alone suggest that the asthma prevalence may be underestimated if based only on the diagnostic label.

Parental perceptions of access to care and quality of care for inner-city children with asthma.

The objective of this study was to describe perceptions of asthma care, morbidity, and health service utilization by parents of children with asthma presenting to an inner-city emergency department (ED). A cross-sectional survey was conducted in an urban pediatric ED, with a convenience sample of 466 parents of children receiving asthma treatment during a consecutive 6-week period in late fall 1995. Parents completed a 30-item survey including sociodemographic data, source of primary medical care and asthma care for their child, selected measures of access to care, and medications used by their child in the week prior to the ED visit. Perceived quality of asthma care was measured by six items (summary score = 0-6) reported to have been performed by the child's asthma doctor: discussion of home peak flow monitoring, child-specific triggers, dogs/cats, smoke, postexacerbation calling instructions, and provision of a written asthma management plan. Functional morbidity was measured by nights of poor sleep, days of cough, and school days missed due to asthma in the previous month. Among 325 patients with previously diagnosed asthma, 308 (97%) were reported to have a source of primary medical care. Of these, 126 respondents identified their primary care provider as the child's usual source of asthma care, while 158 identified the ED as the usual source. The groups did not differ by insurance status, ethnicity, or mean age of the child. Thirty-nine percent of children with the same provider for primary and asthma care compared with 15% of children reported to receive their asthma care predominantly in the ED had used inhaled steroids or cromolyn in the week prior to the ED visit (p < .0001). Children with the same provider for primary and asthma care had a higher mean quality score than children receiving asthma care in the ED (3.7 vs. 2.8, p < 0.0001), but there was no relationship between source of asthma care and functional morbidity. The ED remains the usual source of asthma care for many inner-city children. Among parents surveyed in the ED, there was a significant relationship between source of usual asthma care and quality of care, but a relationship between usual source of asthma care and functional morbidity could not be identified.

Predictors of recurrent febrile seizures. A prospective cohort study.

OBJECTIVES: To define the risk and identify predictors of single and multiple recurrent febrile seizures. METHODS: Children (n = 428) with first febrile seizures were prospectively identified and followed for 2 or more years. Parents were interviewed soon after their children's first febrile seizure and were called every 3 months to ascertain recurrent febrile seizures. Medical records of first and recurrent seizures were reviewed for additional information. RESULTS: A total of 136 children (31.8%) experienced recurrent seizures: 73 (17.1%) had only 1 recurrence, 38 (8.9%) had 2 recurrences, and 25 (5.8%) had 3 or more recurrences. Young age at onset, a history of febrile seizures in a first-degree relative, low degree of fever while in the emergency department, and a brief duration between the onset of fever and the initial seizure were strong independent predictors of recurrent febrile seizures. With these 4 factors combined, it is possible to define groups of children having very high and very low probabilities of having any recurrences (> 70% vs < 20%), having 2 or more recurrences (> 60% vs < 10%), and having 3 or more recurrence (12% vs about 0%). In children who had at least 1 recurrence, age at the time of the first recurrence and a family history of epilepsy were predictors of subsequent recurrences. CONCLUSIONS: In children who have had a first febrile seizure, recurrences are common. The risk for 1 or more recurrences can be meaningfully predicted at the time of the initial febrile seizure with a combination of the 4 factors identified in this study.

Metered-dose inhalers with spacers vs nebulizers for pediatric asthma.

OBJECTIVE: To determine whether the administration of beta-agonists by metered-dose inhaler (MDI) with a spacer device is as effective as the administration of beta-agonists by nebulizer for the treatment of acute asthma exacerbations in children. DESIGN: Randomized trial with two arms. SETTING: Urban pediatric emergency department (ED) in Bronx, NY. PATIENTS: Convenience sample of 152 children 2 years and older with a history of at least two episodes of wheezing presenting to the ED with an acute asthma exacerbation. INTERVENTIONS: Patients were randomly assigned to receive standard doses of a beta-agonist (albuterol) by an MDI with spacer or by a nebulizer. Dosing intervals and the use of other medications were determined by the treating physician. MEASUREMENTS/MAIN RESULTS: Baseline characteristics and asthma history were recorded. Asthma severity score, peak expiratory flow rate in children 5 years or older, and oxygen saturation were determined at presentation and before admission or discharge. The groups did not differ in age, sex, ethnicity, age of onset of asthma, or asthma severity score at presentation. There were no significant differences between the groups in outcomes, including mean changes in respiratory rate, asthma severity score, and peak expiratory flow rate, oxygen saturation, number of treatments given, administration of steroids in the ED, and admission rate. Patients given MDIs with spacers required shorter treatment times in the ED (66 minutes vs 103 minutes, P < .001). Fewer patients in the spacer group had episodes of vomiting in the ED (9% vs 20%, P < .04), and patients in the nebulizer group had a significantly greater mean percent increase in heart rate from baseline to final disposition (15% vs 5%, P < .001). CONCLUSIONS: These data suggest that MDIs with spacers may be an effective alternative to nebulizers for the treatment of children with acute asthma exacerbations in the ED.

Pediatric asthma care in US emergency departments. Current practice in the context of the National Institutes of Health guidelines.

OBJECTIVES: To determine whether US emergency department care for pediatric asthma conforms to the National Institutes of Health guidelines and whether the guidelines are likely to be adopted in clinical practice. DESIGN: Mail survey conducted from January to April 1992, and stratified by hospital type (children's, public and community). SETTINGS: Emergency departments of US hospitals. PARTICIPANTS: Simple stratified random sample of emergency department directors from 376 sampled hospitals. MEASUREMENTS: Self-reported data on emergency department pediatric asthma care, and knowledge and attitudes about the National Institutes of Health guidelines. Data are reported as mean (+/- SE). RESULTS: Sixty-eight percent of the surveyed emergency department directors responded. During 1991, there were an estimated 1.6 million visits for pediatric asthma care. Asthma accounted for 16.9% (+/- 9.0%) of all pediatric emergency department visits. Only 2.1% (+/- 1.0%) reported the use of written protocols or guidelines, with significant variation by hospital type. Sixty-seven percent (+/- 3.0%) reported the use of pulse oximetry. Eighty percent reported the use of beta-agonists by inhalation as the initial treatment. Only 44.7% (+/- 2.9%) reported the use of steroids if there was a poor response to the initial treatment. An estimated 45.5% (+/- 3.9%) of respondents had heard of the guidelines at the time of this survey; approximately 24% reported that they had read the guidelines. Most respondents reported that the guidelines were credible, clear and concise, and likely to be adopted in their emergency department. CONCLUSIONS: These data suggest that reported pediatric asthma care in US emergency departments differs substantially from the National Institutes of Health guidelines, with considerable variation by hospital type. The guidelines appear to provide an acceptable tool for emergency departments to use in assessing their pediatric asthma care. However, in light of the lack of evidence that the guidelines will improve outcomes, the impact of national guideline adoption remains unclear.

Risk factors for a first febrile seizure: a matched case-control study.

We conducted a matched case-control study to identify risk factors for first febrile seizures, with special emphasis on characteristics of the acute illness episode. Cases were identified through hospital emergency departments; controls were identified through outpatient clinics and emergency departments. Sixty-nine children with first febrile seizures and no history of previous unprovoked seizures were matched for age (+/- 6 months), site of routine pediatric care, and date of visit (+/- 2 weeks) with 1 or 2 febrile controls who had no history of previous febrile or unprovoked seizures. Medical records for the index visit were reviewed, and parents were interviewed by telephone. Illness characteristics examined included height of temperature, type of underlying illness, contact with a physician during the illness but before the index visit, and use of acetaminophen or decongestants. Family history of febrile and of unprovoked seizures, sociodemographic characteristics, daycare use, and selected pre- and perinatal variables were also studied. On multivariable analysis, significant independent risk factors were height of temperature, history of febrile seizures in a first- or in a higher degree relative. Gastroenteritis as the underlying illness had a significant inverse (i.e., protective) association with febrile seizures. Maternal smoking during pregnancy was a marginally significant predictor of febrile seizures.

Reduction of morbidity in asthmatic children given a spacer device.

STUDY OBJECTIVE: To evaluate whether providing a spacer device and a single, brief demonstration regarding its proper use would result in earlier resolution of asthma symptoms, improved school attendance, and decreased frequency of unscheduled medical visits for asthma among children receiving noncontinuous care in an urban emergency department (ED). DESIGN: Randomized controlled trial. SETTING: Urban hospital pediatric ED. PARTICIPANTS: Eighty-four children with the chief complaint of asthma. INTERVENTION: Children were enrolled in the ED at the time of an asthma attack and randomly assigned to one of two treatment groups. The spacer group received an inhaled beta-agonist at discharge from the ED with a spacer device. The control group received inhaled or oral beta-agonists without a spacer device. Both groups received other medications at the discretion of the evaluating physician who was not the interviewer in any case. A baseline questionnaire was completed and follow-up by telephone was done at 1 week, and 2, 4, and 6 months after enrollment. MEASUREMENTS AND RESULTS: The spacer group reported significantly earlier resolution of wheezing (0 days vs 2 days, p < 0.01) at the 2- and 4-month follow-up assessments. They reported significantly fewer days of cough after an asthma attack at 2 months (1 day vs 3 days, p < 0.01) and 4 months (0 days vs 3 days, p < 0.01). The spacer group missed significantly fewer days of school following an asthma attack at 2 and 4 months (0 days vs 2 days, p = 0.05). There was no difference between the two groups on any outcome measures at the 1-week and 6-month follow-up assessments. CONCLUSIONS: Introducing a spacer device to patients in a busy, inner-city pediatric ED is an effective and efficient intervention that improves the functioning of asthmatic children in terms of resolution of cough and wheeze and school absenteeism.

An estimate of the prevalence of asthma and wheezing among inner-city children.

OBJECTIVE: To estimate the prevalence of asthma and wheezing unassociated with a diagnosis of asthma among inner-city children. DESIGN: Cross-sectional survey of a sample of Bronx households. METHODS: Random digit dialing telephone survey using parental report. SETTING: Bronx County, NY. PARTICIPANTS: 662 self-designated heads-of-household who reported for all children 0 through 17 years of age living in their households. MEASUREMENTS: Questions from the Child Health Supplement to the 1988 National Health Interview Survey and the International Union Against Tuberculosis and Lung Disease Bronchial Symptoms Questionnaire were used to estimate the prevalence of asthma and wheezing-related illness. RESULTS: Information was gathered on 1285 children. Of this sample, 184 (14.3%) were reported to have ever had asthma (cumulative prevalence) and 111 (8.6%) were reported to have asthma in the last 12 months (period prevalence). The asthma period prevalence rate among Bronx children was twice the United States rate (4.3%). Among children 0 through 11 years of age, the prevalence rate was similar for boys and girls, although among children 12 through 17 years of age, asthma was significantly more prevalent among boys. Fifty-four children (4.2%) were reported to have had wheezing in the past 12 months unassociated with a diagnosis of asthma (wheeze only). The cumulative, but not the period, prevalence rate of asthma differed significantly by income and race/ethnicity. The cumulative prevalence was significantly higher among Hispanics and children from the lowest income families. The prevalence of wheeze only (no reported history of asthma) was higher among whites (6.4%) and blacks (5.8%) than Hispanics (2.9%) (P < .1). The reported number of wheezing attacks and the average number of nights per week that sleep was disturbed by wheezing during the past year were similar for those with asthma and those with wheeze only, although severe attacks (wheezing severe enough to limit speech) were significantly more likely among those reported to have asthma (P < .001). The total asthma prevalence (period prevalence of asthma plus wheeze only) was 12.8% and was quite consistent across subgroups. CONCLUSIONS: These data suggest that the prevalence of asthma among inner-city children may be substantially higher than the rates for this group estimated from national survey data. Some proportion of the wheeze only group may represent undiagnosed, and thereby undertreated, asthma. Public health efforts directed at reducing asthma morbidity and mortality need to address the possibility that asthma prevalence is higher within inner cities and that a large number of children with asthma may be inadequately diagnosed and treated.

A prospective study of recurrent febrile seizures.

BACKGROUND: Febrile seizures occur in about 2 to 4 percent of all children, approximately one third of whom will have recurrent febrile seizures. Little is known about predictors of recurrence. METHODS: In this prospective study, we identified 347 children (1 month to 10 years of age) who presented with a first febrile seizure at one of four pediatric emergency departments. Information about these children was collected from medical records and interviews with the parents, and the children were followed for a median of 20 months to ascertain whether febrile seizures recurred. RESULTS: Recurrent febrile seizures occurred in 94 of the 347 children (27 percent) with a cumulative risk of 25 percent at one year and 30 percent at two years. The duration of fever before the initial seizure was associated with the risk of recurrence at one year: for fever lasting less than 1 hour, the risk of recurrence was 44 percent; for fever lasting 1 to 24 hours, 23 percent; and for fever lasting more than 24 hours, 13 percent (P less than 0.001). With each degree of increase in temperature (in degrees Fahrenheit), from 101 degrees F (38.3 degrees C) to greater than or equal to 105 degrees F (40.6 degrees C), the risk of recurrence at one year declined, from 35 percent to 30, 26, 20, and 13 percent (P for trend = 0.024). An age of less than 18 months and a family history of febrile seizures were also associated with an increased risk of recurrence. A family history of epilepsy, complex febrile seizures, and neurodevelopmental abnormalities did not increase the risk of recurrent febrile seizures. CONCLUSIONS: A shorter duration of fever before the initial febrile seizure and a lower temperature are associated with an increased risk of recurrence in children who have febrile seizures.
