Background: The growth of managed health care in the United States has been accompanied by controls on access to specialty physician services. We examined the relationship of physician specialty to treatment and outcomes of patients with asthma in managed care plans., Methods: We conducted a mail survey of adult asthma patients who were enrolled in 12 managed care organizations and had at least 2 contacts for asthma (International Classification of Diseases, Ninth Revision, Clinical Modification code 493.x) during the previous 24 months; we also surveyed their treating physicians. This report concerns 1954 patients and their 1078 corresponding physicians. Treatment indicators included use of corticosteroid inhalers, use of peak flow meters, allergy evaluation, discussion of triggers, and patient self-management knowledge. Outcome measures included canceled activities, hospitalization or emergency department visits, asthma attacks, workdays lost, asthma symptoms, physical and mental health, overall satisfaction with asthma care, and satisfaction with communication with physicians and nurses., Results: Significant differences were noted for patients of specialists and experienced generalists compared with those of generalist physicians. Peak flow meter possession was reported by 41.9% of patients of generalists, 51.7% of patients of experienced generalists, and 53.8% of patients of pulmonologists or allergists. Compared with patients of generalists, outcomes were significantly better for patients of allergists with regard to canceled activities, hospitalizations and emergency department visits for asthma, quality of care ratings, and physical functioning. Patients of pulmonologists were more likely to rate improvement in symptoms as very good or excellent., Conclusions: In a managed health care setting, physicians' specialty training and self-reported expertise in treating asthma were related to better patient-reported care and outcomes.

Objective: To determine whether care for children was more consistent with national asthma guidelines when a specialist rather than a generalist was the usual source of asthma care., Design: Cross-sectional survey., Setting: Two large managed care organizations in the United States., Participants: A total of 260 parents of children with asthma., Interventions: None., Main Outcome Measures: Parent reports of the physician primarily responsible for asthma care (specialist, generalist, or both equally) and whom they would call (specialist or generalist) for questions about asthma care were used to define usual source of care. We assessed consistency of care with 1997 National Asthma Education and Prevention Program guidelines using 11 indicators in 4 domains of asthma care: patient education, control of factors contributing to asthma symptoms, periodic physiologic assessment and monitoring, and proper use of medications., Results: In all 4 domains, care was more likely to be consistent with guidelines when specialists were the usual source of care. These differences remained after adjustment for symptom severity, recent care encounters, and parent demographics. Greatest differences for specialist versus generalist management were for use of controller medications (odds ratio [OR] 6.7; 95% confidence interval [CI]: 1.5-30.4), ever having a pulmonary function test (OR 6.5; 95% CI: 2.4-18.1), and having been told about asthma triggers and how to avoid them (OR 5.9; 95% CI: 1.3-26.2)., Conclusions: In these managed care organizations, asthma care in children was more likely to be consistent with national guidelines when a specialist was the primary provider. Greater use of specialists or altering generalist physicians' care may improve the degree to which the care of children with asthma is consistent with national guidelines.

Background: In the United States, morbidity from asthma disproportionately affects African Americans and women. Although inadequate care contributes to overall asthma morbidity, less is known about differences in asthma care by race and sex., Subjects and Methods: To examine the relationships of race and sex with asthma care, we analyzed responses to questionnaires administered to adults enrolled in 16 managed care organizations participating in the Outcomes Management System Asthma Study between September and December 1993. Indicators of care consistent with National Asthma Education and Prevention Program (1991) recommendations were assessed. Of a random sample of 8640 patients asked to participate, 6612 (77%) completed the survey. This study focused on 5062 (14% African American, 72% women) patients with at least moderate asthma symptom severity., Results: Fewer African Americans than whites reported care consistent with recommendations for medication use (eg, daily inhaled corticosteroid use, 34.9% vs 54.4%; P =.001), self-management education (eg, action plan, 42.0% vs 53.8%; P =.001), avoiding triggers (37.6% vs 53.6%; P =.001), and specialist care (28.3% vs 41.0%; P =.001). Differences in asthma care by sex were smaller and tended to favor women except for daily inhaled corticosteroid use (women vs men: 49.6% vs 58.3%; P =.001) and having specialist care (37.7% vs 43.1%; P =.001). Similar race and sex differences were observed after adjusting for age, education, employment, and symptom frequency., Conclusions: Even among patients with health insurance, disparities in asthma care for African Americans compared with whites exist and may contribute to race disparities in outcomes. Women generally reported better asthma care but may benefit from greater use of inhaled corticosteroids.

Objective: To evaluate the consistency of pediatric asthma care with the National Asthma Education and Prevention Program Guidelines., Design: Cross-sectional survey at 2 managed care organizations in the United States (winter 1997-1998). The participants were parents of children (n = 318) age 5 to 17 years with asthma. There were no interventions. The outcome measures were indicators of care in 4 domains: (1) periodic physiologic assessment, (2) proper use of medications, (3) patient education, and (4) control of factors contributing to asthma severity., Results: Of 533 eligible patients with asthma, 318 (60%) parents responded; 59% of children were male, 76% were white, and 60% were aged 5 to 10 years. Deficiencies in care were identified in all care domains including, for patients with moderate and severe persistent symptoms, only 55% used long-term control medication daily, 49% had written instructions for handling asthma attacks, 44% had instructions for adjustment of medication before exposures, 56% had undergone allergy testing, and 54% had undergone pulmonary function testing., Conclusions: There are significant opportunities to improve the quality of care for children with asthma enrolled in managed care. A comprehensive approach to improving care may be necessary to address multiple aspects of care where opportunities exist.
