Parental impressions of the benefits (pros) and barriers (cons) of follow-up care after an acute emergency department visit for children with asthma.
OBJECTIVE: Asthma morbidity, with increasing emergency department (ED) visits, is prevalent among low-income, urban children. Follow-up care after ED visits is infrequent. We developed and evaluated an instrument that describes the parental benefits (pros) and barriers (cons) of obtaining follow-up care for interventions to promote follow-up. METHODS: We enrolled a convenience sample of low-income, urban parents who brought their children to the ED for treatment of asthma. These parents rated 41 items about the pros and cons of making a follow-up visit. Principal component analysis was used to identify the underlying structure of the instrument. RESULTS: One hundred forty-seven participants were interviewed in the ED. Principal component analysis retained 24 total items, which were identified by this sample as highly associated with deciding to take their child to a follow-up visit. Two types of pros were identified, informational and attitudinal, including "ask the doctor questions," and " children with asthma are healthier if they see their doctor regularly." Two types of cons were identified, practical and attitudinal, including "I have to find transportation," and "I don't need to see the doctor unless my child is sick." The mean total pro and con scores were 4.05 +/- 0.63 and 1.73 +/- 0.67, respectively. CONCLUSIONS: The pros and cons are not unidimensional. Even among those with infrequent follow-up, pros were endorsed more highly than cons. Programs that target these pros and cons may improve adherence to follow-up and regular care for low-income urban children.

Defining asthma in the preschool-aged child.
A physician faces many challenges in making a definitive diagnosis of asthma in young children. Although there are clinical and historical features consistent with asthma, identical features are present in many other diseases. Furthermore, there is no specific test for asthma. Other diseases must always be ruled out before a definitive diagnosis of asthma is made. Determining whether cough or wheeze is the primary symptom is important because asthma is primarily a wheezing disease. Sweat chloride testing, chest radiography, and allergy skin testing should be performed in children with persistent wheezing to rule out other causes and help support a diagnosis of asthma. Allergy skin testing provides particularly useful information for making a diagnosis of asthma in the preschool-aged child. A chart review of patients presenting consecutively to the Division of Allergy and Pulmonary Medicine provides insight and information on an approach to make an asthma diagnosis for this population.

Feasibility of a national fatal asthma registry: more evidence of IRB variation in evaluation of a standard protocol.
PURPOSE: Approximately 4,500 Americans die from asthma each year. Our objective was to determine the feasibility of creating a national fatal asthma registry to better understand this problem.Methods. Using a standard questionnaire, 18 state vital statistics departments and 22 medical examiners offices were contacted in 2001 to assess availability of fatal asthma data. Funding was obtained in 2002 to implement a fatal asthma registry. During 2003, the project was put on hold due to uncertainty about the impact of the Health Insurance Portability and Accountability Act (HIPAA). The project was revived in 2004 when a standard protocol was submitted to Institutional Review Boards (IRBs) in four different states. RESULTS: All vital statistics departments reported that they were able to identify the decedent's name and demographic characteristics. Contact information for a relative or doctor was available in all states. Demographic characteristics and autopsy findings were available from 100% of the medical examiners offices. However, IRBs at the four institutions required major protocol modifications, including language and approach for contacting next of kin. CONCLUSION: Availability of demographic and clinical data across states is consistent. The creation of a national fatal asthma registry appears feasible, but different IRB interpretations of what is permissible preclude a standard approach across states.

Socioeconomic status, stress, and immune markers in adolescents with asthma.
OBJECTIVE: Previous research has demonstrated links between low socioeconomic status (SES) and clinical asthma outcomes, as well as links between stress and asthma. The objective of this study was to test whether adolescents with asthma from different SES backgrounds differed in biological profiles relevant to asthma, including immune and cortisol measures. The second objective was to test whether psychological stress and control beliefs could explain these differences. MATERIALS AND METHODS: Adolescents with persistent asthma from either low (N= 18) or high (N= 12) SES neighborhoods were interviewed about their stress experiences (chronic stress, acute life events, interpretations of ambiguous life events) and control beliefs. Blood was drawn to assess immune (cytokines, eosinophils, IgE) and neuroendocrine (cortisol) markers associated with asthma. RESULTS: Adolescents in the low SES group had significantly higher levels of a stimulated cytokine associated with a Th-2 immune response (IL-5), higher levels of a stimulated cytokine associated with a Th-1 immune response (IFN-gamma), and marginally lower morning cortisol values compared with the high SES group. Low SES adolescents also had greater stress experiences and lower beliefs about control over their health. Statistical mediational analyses revealed that stress and control beliefs partially explained the relationship between SES and IL-5/IFN-gamma. CONCLUSION: Our finding that low SES was associated with elevations in certain immune responses (IL-5/IFN-gamma) in adolescents with asthma suggests the importance of further exploration into relationships between SES and Th-2/Th-1 responses in asthma. Our findings also suggest that psychological stress and control beliefs may provide one explanation for links between SES and immune responses in childhood asthma.
