Impact of physician asthma care education on patient outcomes.

OBJECTIVE. We evaluated the effectiveness of a continuing medical education program, Physician Asthma Care Education, in improving pediatricians’ asthma therapeutic and communication skills and patients’ health care utilization for asthma. METHODS. We conducted a randomized trial in 10 regions in the United States. Primary care providers were recruited and randomly assigned by site to receive the program provided by local faculty. The program included 2 interactive seminar sessions (2.5 hours each) that reviewed national asthma guidelines, communication skills, and key educational messages. Format included short lectures, case discussions, and a video modeling communication techniques. We collected information on parent perceptions of physicians’ communication, the child’s asthma symptoms, and patients’ asthma health care utilization. We used multivariate regression models to determine differences between control and intervention groups. RESULTS. A total of 101 primary care providers and a random sample of 870 of their asthma patients participated. After 1 year, we completed follow-up telephone interviews with the parents of 731 of the 870 patients. Compared to control subjects, parents reported that physicians in the intervention group were more likely to inquire about patients’ concerns about asthma, encourage patients to be physically active, and set goals for successful treatment. Patients of physicians that attended the program had a greater decrease in days limited by asthma symptoms (8.5 vs 15.6 days), as well as decreased emergency department asthma visits (0.30 vs 0.55 visits per year). CONCLUSIONS. The Physician Asthma Care Education program was used in a range of locations and was effective in improving parent-reported provider communication skills, the number of days affected by asthma symptoms, and asthma health care use. Patients with more frequent asthma symptoms and higher health care utilization at baseline were more likely to benefit from their physician’s participation in the program.

Issues in identifying asthma and estimating prevalence in an urban school population

UNLABELLED This article first presents salient issues related to identifying children in urban schools who might benefit from asthma services. It discusses a brief questionnaire for identifying cases and problems in estimating asthma prevalence. Subsequently, results of case detection in 14 urban schools are presented and discussed in light of these issues. The questionnaire was employed with parents of 4,653 African-American children in Detroit. Results suggest that determining number, type, and frequency of symptoms may be necessary to ascertain prevalence of asthma. Using only number and type produced a rate of asthma of 25%. Adding frequency provided a more conservative estimate of 19%. About 9% of children exhibiting symptoms of asthma had no physician diagnosis. Only 25% with symptoms reflecting mild persistent, 35% with moderate persistent, and 26% with severe persistent disease had prescriptions for anti-inflammatory medicine. Further, 23% of children with asthma-like symptoms had no prescription for asthma medicine of any type. CONCLUSIONS (1) low-cost procedures can be used in schools to identify children with suspected undiagnosed and undertreated asthma; (2) prevalence estimates for asthma in the group of urban school children studied are among the highest in the United States; and (3) asthma is undertreated in this sample.

Asthma and the unified airway

Inflammatory processes of the upper and lower airway commonly co-exist. Patients with upper respiratory illnesses such as allergic rhinitis and acute and chronic rhinosinusitis often present to both otolaryngologists and primary care physicians for treatment of their symptoms of nasal and sinus disease. These patients often have concurrent lower respiratory illnesses such as asthma that may be contributing to their overall symptoms and quality of life. Unfortunately, asthma frequently remains undiagnosed in this population. It was the objective of this paper to examine the relationship between upper respiratory illnesses such as rhinitis and rhinosinusitis and lower respiratory illnesses such as asthma, and to provide a framework for primary care and specialty physicians to approach these illnesses as a spectrum of inflammatory disease. The present manuscript was developed by a multidisciplinary workgroup sponsored by the American Academy of Otolaryngic Allergy. Health care providers in various specialties contributed to the manuscript through preparation of written materials and through participation in a panel discussion held in August 2006. Each author was tasked with reviewing a specific content area and preparing a written summary for inclusion in this final document. Respiratory inflammation commonly affects both the upper and lower respiratory tracts, often concurrently. Physicians who are treating patients with symptoms of allergic rhinitis and rhinosinusitis must be vigilant to the presence of asthma among these patients. Appropriate diagnostic methods should be used to identify individuals with concurrent respiratory illnesses, and comprehensive treatment should be instituted to reduce symptoms and improve quality of life.

Identification of gaps in the diagnosis and treatment of childhood asthma using a community-based participatory research approach

The goal of this investigation was to use a community-based participatory research approach to develop, pilot test, and administer an asthma screening questionnaire to identify children with asthma and asthma symptoms in a community setting. This study was conducted as the recruitment effort for Community Action Against Asthma, a randomized trial of a household intervention to reduce exposure to environmental triggers of asthma and was not designed as a classic prevalence study. An asthma screening questionnaire was mailed and/or hand delivered to parents of 9,627 children, aged 5 to 11 years, in two geographic areas of Detroit, Michigan, with predominantly African American and Hispanic populations. Additional questionnaires were distributed via community networking. Measurements included parent report of their childs frequency of respiratory symptoms, presence of physician diagnosis of asthma, and frequency of doctor-prescribed asthma medication usage. Among the 3,067 completed questionnaires, 1,570 (51.2% of returned surveys, 16.3% of eligible population) were consistent with asthma of any severity and 398 (12.9% of returned surveys, 4.1% of eligible population) met criteria, for moderate-to-severe asthma. Among those meeting criteria for moderate-to-severe asthma, over 30% had not been diagnosed by a physician, over one half were not taking daily asthma medication, and one quarter had not taken any physician-prescribed asthma medication in the past year. Screening surveys conducted within the context of a community-based participatory research partnership can identify large numbers of children with undiagnosed and/or undertreated moderate-to-severe asthma. These children are likely to benefit from interventions to reduce morbidity and improve quality of life.

Executive Summary: Asthma and the Unified Airway

Asthma is a common comorbid disorder that will be seen by otolaryngologists in their treatment of patients with rhinitis, rhinosinusitis, and otitis media. Among otolaryngologists, however, a diagnosis of asthma is infrequently considered in this patient population. Otolaryngologists, however, may be in an important position to recognize this potential diagnosis and provide treatment or appropriate referral. To further develop this relationship among upper and lower airway inflammation, and to provide important information to otolaryngologists regarding this relationship, a multidisciplinary workgroup was impaneled by the American Academy of Otolaryngic Allergy in August 2006. The full report of this meeting is published separately as a Supplement to Otolaryngology-Head and Neck Surgery. This Executive Summary provides a brief synopsis of that document, with a focus on comorbid respiratory inflammation for otolaryngologists. In the treatment of their patients with allergic rhinitis and rhinosinusitis, otolaryngologists must be aware of the possible presence of asthma so that appropriate treatment and/or referral can be initiated. The impact of this practice will allow more comprehensive treatment of patients with upper and lower airway disease, and will improve patient symptoms, function, and quality of life.

Treatment of Anorexia and Weight Loss With Megestrol Acetate in Patients With Cystic Fibrosis

Four patients with severe cystic fibrosis lung disease, anorexia and weight loss, received Megestrol Acetate (MA), as an appetite stimulant. The initial dose was 400–800 mg daily and was continued for 6–15 months. Appetite was improved, with significant weight gain in all patients and an increase in their weight for age percentile from <5% at the start of the study to approximately the 25th percentile after 6 months of use and improvement in quality of life. One patient discontinued MA after 6 months, and subsequently appetite and weight were depressed. Pediatr Pulmonol. 1999; 28:380–382.

Schools' Capacity to Help Low-Income, Minority Children to Manage Asthma.

This article describes the challenges and strengths of asthma management in 14 low-income, predominantly African American urban elementary schools serving more than 5,000 students. Asthma prevalence was 24.5%. Teachers, school principals, parents, and children described how asthma was managed at school. Data from classmates of students with asthma showed that they had moderate to high levels of information about the disease. Data from teachers indicated the great need for practical instruction on how they might effectively support a child with asthma in the classroom and on the playground. Principals raised concerns about expectations for the functioning of school staff and implementation of school policies especially related to asthma emergencies. Parents reported a range of problems their children face at school. Data from children with asthma showed that 75% believed asthma affected their schoolwork. Findings from this study should be useful to school personnel, health providers, and others who assist children and their families to manage asthma at school. Data suggest that making school nursing services available is warranted, given the impact of asthma on the school community.

Long-term safety and asthma control measures with a budesonide/formoterol pressurized metered-dose inhaler in African American asthmatic patients: A randomized controlled trial

BACKGROUND Information surrounding the long-term safety of combination inhaled corticosteroid/long-acting β(2)-adrenergic agonist medications in African American asthmatic patients is limited. OBJECTIVE We sought to assess safety and asthma control with a budesonide/formoterol pressurized metered-dose inhaler (pMDI) versus budesonide over 1 year in African American patients. METHODS This 52-week, randomized, double-blind, parallel-group, multicenter, phase 3B safety study (NCT00419952) was conducted in 742 self-reported African American patients 12 years or older with moderate-to-severe asthma previously receiving medium- to high-dose inhaled corticosteroids. After 2 weeks using a 320 μg twice-daily budesonide pMDI, patients were randomized 1:1 to 320/9 μg twice-daily budesonide/formoterol pMDI or 320 μg twice-daily budesonide pMDI. RESULTS Both treatments were well tolerated. Asthma exacerbation incidence and rate (per patient-treatment year) were lower with budesonide/formoterol versus budesonide (incidence, 7.7% vs 14.0% [P= .006]; rate ratio, 0.615 [P= .002]). Time to first asthma exacerbation was longer (P= .018) with budesonide/formoterol versus budesonide. The most common adverse events, regardless of study drug relationship, were headache (9.5% and 7.7%), nasopharyngitis (6.9% and 8.0%), sinusitis (4.0% and 6.3%), and viral upper respiratory tract infection (5.8% and 4.4%) for budesonide/formoterol and budesonide, respectively. Serious adverse events occurred in 12 and 15 patients, respectively; none were considered drug related. No substantial or unexpected patterns of abnormalities were observed in laboratory, electrocardiographic, or Holter monitoring assessments. Hospitalization caused by asthma exacerbation occurred in 0 and 4 patients in the budesonide/formoterol and budesonide groups, respectively. Pulmonary function and asthma control measures generally favored budesonide/formoterol. CONCLUSIONS In this population budesonide/formoterol pMDI was well tolerated over 12 months, with a safety profile similar to that of budesonide; the asthma exacerbation rate was reduced by 38.5% versus budesonide.

Asthma outcomes in children and adolescents with multiple morbidities: Findings from the National Health Interview Survey.

BACKGROUND More Americans are managing multiple chronic conditions (MCCs), and trends are particularly alarming in youth. OBJECTIVE The purpose of this study was to examine the prevalence and distribution of 9 chronic conditions in children and adolescents with and without asthma, and adverse asthma outcomes associated with having MCCs. METHODS Cross-sectional interview data from the National Health Interview Survey were analyzed (N = 66,790) between 2007 and 2012 in youth 0 to 17 years of age. Bivariate analysis methods and multivariate generalized linear regression were used to examine associations. RESULTS Five percent of children with asthma had 1 or more coexisting health conditions. The prevalence of 1 or more comorbidities was greater among those with asthma than those without (5.07% [95% CI: 4.5-5.6] vs. 2.73% [95% CI: 2.6-2.9]). Those with asthma were twice as likely to have co-occurring hypertension (prevalence ratio [PR] = 2.2 [95% CI: 1.5-3.2]) and arthritis (PR = 2.7 [95% CI: 1.8-4.0]) compared with those without asthma. Every additional chronic condition with asthma was associated with a greater likelihood of an asthma attack (PR = 1.1 [95% CI: 1.0-1.2]), all-cause emergency department visits (PR = 1.3 [95% CI: 1.1-1.5]), and missed school days (PR = 2.3 [95% CI: 1.7-3.2]). CONCLUSIONS Children and adolescents with asthma in the US who suffer from MCCs have increased asthma symptoms, missed school days, and all-cause emergency department visits. Further research on optimal management strategies for this group is needed.
