Mobile health care operations and return on investment in predominantly underserved children with asthma: the breathmobile program.

Underserved populations have limited access to care. Improved access to effective asthma care potentially improves quality of life and reduces costs associated with emergency department (ED) visits. The purpose of this study is to examine return on investment (ROI) for the Breathmobile Program in terms of improved patient quality-adjusted life years saved and reduced costs attributed to preventable ED visits for 2010, with extrapolation to previous years of operation. It also examines cost-benefit related to reduced morbidity (ED visits, hospitalizations, and school absenteeism) for new patients to the Breathmobile Program during 2008-2009 who engaged in care (≥3 visits). This is a retrospective analysis of data for 15,986 pediatric patients, covering 88,865 visits, participating in 4 Southern California Breathmobile Programs (November 16, 1995-December 31, 2010). The ROI calculation expressed the cost-benefit ratio as the net benefits (ED costs avoided+relative value of quality-adjusted life years saved) over the per annum program costs (∼$500,000 per mobile). The ROI across the 4 California programs in 2010 was $6.73 per dollar invested. Annual estimated emergency costs avoided in the 4 regions were $2,541,639. The relative value of quality-adjusted life years saved was $24,381,000. For patients new to the Breathmobile Program during 2008-2009 who engaged in care (≥3 visits), total annual morbidity costs avoided per patient were $1395. This study suggests that mobile health care is a cost-effective strategy to deliver medical care to underserved populations, consistent with the Triple Aims of Therapy.

Achieving and maintaining asthma control in inner-city children.

BACKGROUND: Despite guidelines-defined care, inner-city children of low socioeconomic status have poor asthma control. OBJECTIVE: This study evaluated time to achieve control, maintenance of control, and factors associated with well controlled asthma for pediatric patients receiving specialty-based asthma care in mobile asthma clinics designed to reduce barriers to delivering effective asthma care (the Breathmobile Program). METHODS: Existing clinical data collected from January 1998 to June 2008 for 7822 pediatric patients with asthma (34,339 visits) enrolled in similarly structured mobile asthma programs across the United States evaluated the effect of asthma control on the reduction of asthma-related morbidity, time to achieve asthma control, maintenance of asthma control, and factors associated with well controlled asthma. RESULTS: Comparison of pre and post year data for subjects enrolled in the program for at least 1 year revealed reductions in the percentage of patients reporting emergency department visits (mean, 66%), hospitalizations (mean, 84%), and missed school days ≥5/year (mean, 78%). Well controlled asthma was achieved by visit 3 for an estimated 80% of patients. Factors contributing to well controlled asthma include non-African American race, visit interval <90 days, and adherence to prescribed therapy. CONCLUSION: This study demonstrates the ability to achieve and maintain asthma control in high-risk populations in association with intensive, accessible, guidelines-defined care with close follow-up.
