Patterns of rescue and maintenance therapy claims surrounding a clinical encounter for an asthma exacerbation.

BACKGROUND: A "window of opportunity" has been proposed where anti-inflammatory therapy administration in response to symptoms could prevent exacerbation. OBJECTIVE: To evaluate rescue and maintenance therapy claims surrounding a severe asthma exacerbation serious enough to require a face-to-face clinical encounter. METHODS: Merative MarketScan research databases (US administrative claims 2011 to 2017) were analyzed for patients aged ≥4 years, with an asthma diagnosis code, who filled short-acting ß2-agonist (SABA) and Global Initiative for Asthma Steps 3 to 5 maintenance therapies. Patients were indexed on a random SABA claim and had 12 months' continuous health plan eligibility pre- and post-index. Serious exacerbations were severe exacerbations requiring systemic corticosteroids prescribed from an outpatient clinic, urgent care or emergency department, or hospitalization for asthma. SABA and maintenance claims 30 days pre- and post-event were analyzed. RESULTS: Of 319,342 patients (30% children 4 to 11 years; 70% adults or adolescents ≥12 years), 27.2% of children and 16.8% of adolescents or adults experienced ≥ 1 serious exacerbation (unadjusted odds ratio [OR], 1.85 [95% confidence interval, 1.81-1.88]). In the 30 days pre-event, 42.6% filled ≥1 SABA (children: 44.3%; adolescents or adults: 41.5%; OR, 1.12 [1.09-1.16]) and 57.4% filled maintenance (children: 59.0%; adolescents or adults: 56.3%; OR, 1.12 [1.08-1.15]). In the 30 days post-event, 61.4% filled SABA (children: 69.7%; adolescents or adults: 55.6%; OR, 1.84 [1.78-1.90]) and 94.8% filled maintenance (children: 98.6%; adolescents or adults: 92.2%; OR, 6.09 [5.45-6.81]). CONCLUSION: Many patients treated as having moderate-to-severe asthma escalate SABA claims before a serious exacerbation, but approximately 40% have no anti-inflammatory maintenance fill, highlighting a "window of opportunity" to prevent exacerbations using inhaled corticosteroids concomitantly with SABA as rescue.

Demographics, Treatment Patterns, and Morbidity in Patients with Exercise-Induced Bronchoconstriction: An Administrative Claims Data Analysis.

PURPOSE: Exercise-induced bronchoconstriction (EIB) is generally treated with short-acting ß2-agonists (SABA) before exercising, to prevent symptoms. Real-world data on treatments and outcomes for patients with EIB alone (EIBalone), or with asthma (EIBasthma), in the USA are limited. This study compared demographics, treatment patterns, morbidity, and costs of treating EIB between these two groups of patients. PATIENTS AND METHODS: Administrative claims from US IBM® MarketScan® Research databases were analyzed retrospectively. Patients aged ≥4 years filling a SABA claim between 1/1/2011 and 12/31/2016 were evaluated. Patients were indexed on a random SABA claim and required to have 12 months' continuous eligibility pre- and post-index, ≥1 maintenance medication and/or SABA fill post-index, and were designated EIBalone or EIBasthma according to diagnostic codes (EIB only or EIB plus asthma, respectively). Descriptive statistics were used. RESULTS: In total, 13,480 patients had EIBalone and 14,862 had EIBasthma. Compared with EIBasthma, the EIBalone group was older (mean[SD] 20.4[13.6] vs 17.8[13.6] years), had more females (60.7% vs 54.7%), and filled fewer SABA claims (1.9[1.4] vs 2.5[2.2]) (all p<0.001). A smaller proportion of patients in the EIBalone than EIBasthma group had maintenance therapy claims (79.9% vs 90.6%, p<0.001). The EIBalone group also had a lower proportion of patients with oral or injectable corticosteroid claims (29.4% vs 32.0%) and asthma and/or EIB-related emergency department (1.0% vs 13.0%) or outpatient visits (65.1% vs 72.3%; all p<0.0001). Annual days' supply of oral corticosteroids was similar between groups (mean[SD] EIBalone: 20.7[30.8] vs EIBasthma: 19.8[28] days). CONCLUSION: Individuals with EIBalone or EIBasthma demonstrate considerable morbidity. New treatment paradigms may be needed to optimize outcomes for both patient groups.

The urban and community health pathway: preparing socially responsive physicians through community-engaged learning.

One of five options for the new required Medical College of Wisconsin Pathways program, the Urban and Community Health Pathway (UCHP), links training with community needs and assets to prepare students with the knowledge, skills, and attitudes to provide effective care in urban, underserved settings; promote community health; and reduce health disparities. Students spend at least 10 hours per month on pathway activities: 4 hours of core material delivered through readings, didactics, case discussions, and site visits; and at least 6 hours of experiential noncore activities applying core competencies, guided by an Individualized Learning Plan and faculty advisor. Noncore activities include community-engaged research, service-learning activities or other relevant experiences, and submission of a synthesis paper addressing pathway competencies. The first cohort of students began their pathways in January 2010. Of 560 participating students, 95 (of which 48 were first-year, 21 second-year, and 26 third-year students) selected UCHP. Core sessions focused on public health, social determinants, cultural humility, poverty, the local healthcare system, and safety net. During noncore time, students engaged in projects addressing homelessness, obesity, advocacy, Hmong and Latino health, HIV, asthma, and violence prevention. Students enjoyed working with peers across classes and favored interactive, community-based sessions over didactics in the classroom. Students' papers reflected a range of service and scholarly activities and a deepened appreciation of social and economic influences on health. The UCHP enriches the traditional curriculum with individualized, community-based experiences to build knowledge about health determinants and skills in partnering with communities to improve health.
