Asthma Program Manager

Low-income adults with uncontrolled asthma saw both their asthma control and quality of life improve with the help of an in-home, self-management asthma support program delivered by community health workers (CHWs), according to a report published online by JAMA Internal Medicine.

Asthma affects 24.6 million American, including 17.5 million adults. Control of asthma is inadequate despite the availability of effective methods to manage it. Home-based self-management support to improve asthma control among children is well established. However, the effectiveness of home visits for adults has not been well studied.

James Krieger, M.D., M.P.H., of Public Health-Seattle and King County, Washington, and co-authors report on the Home-Based Asthma Support and Education trial (HomeBASE). The study enrolled 366 participants with uncontrolled asthma: 189 to usual care and 177 to the intervention, which included CHWs who provided education, support and service coordination during home visits. The CHWs provided an average of 4.9 home visits during a one-year period.

The intervention group had greater increases in the average number of symptom-free days over two weeks (2.02 days per two weeks more) and quality of life as measured on a questionnaire increased an average of 0.50 points. However, average urgent health care use episodes in the past 12 months decreased similarly in both groups from an average of 3.46 to 1.99 episodes in the intervention group and from an average of 3.30 to 1.96 episodes in the usual care group.

“We anticipate that this intervention could be readily replicated by health organizations serving diverse, low-income clients, suggesting that it could reduce asthma-related health inequities. Intervention protocols can be implemented without specialized training or resources. The cost per participant was approximately $1,300 (2013 U.S. dollars), substantially less than one year’s supply of an inhaled corticosteroid,” the study concludes.

Community health workers (CHWs) have shown, time and again, that they can improve health outcomes while reducing healthcare costs. Reductions in chronic illness, improved medication adherence, more patient involvement, and better community health have been accompanied by a return on investment of more than $2 for every dollar invested.

One approach states have explored to counteract these barriers is to develop some sort of CHW credentialing system. The goals of credentialing, as described by Carl Rush in 2012, are to achieve greater respect for CHWs among other healthcare professions, improved financial compensation and working conditions, increased job stability, and opportunities for more sustainable funding. The connection between insurance reimbursement and credentialing or standardized training is particularly significant, as both public and private insurance plans are likely to require some form of credentialing in order to pay for CHW services. At the same time, many CHWs are concerned that credentialing will create barriers to entry for the individuals best suited to the job (i.e., members of low-income communities who may not speak English as a first language), and/or take CHWs away from their community connections by focusing on credentialed ―skills‖ over community relationships.

This report by Harvard Law School's Center for Health Law & Policy Innovation is designed to review some of the major policies in different states and highlight some of the issues that arise in these programs. There is no single right approach. With sufficient stakeholder engagement, each state can develop policies tailored for its community.

Abstract:
Background –
Racial disparities in childhood asthma have been a long-standing target for intervention, especially disparities in hospitalization and mortality.

Objectives –
Describe trends in racial disparities in asthma outcomes using both traditional population-based rates and at-risk rates (based on the estimated number of children with asthma) to account for prevalence differences between race groups.

Methods –
Estimates of asthma prevalence and outcomes (emergency department [ED] visits, hospitalizations, and deaths) were calculated from national data for 2001 to 2010 for black and white children. Trends were calculated using weighted loglinear regression, and changes in racial disparities over time were assessed using Joinpoint.

Results –
Disparities in asthma prevalence between black and white children increased from 2001 to 2010; at the end of this period, black children were twice as likely as white children to have asthma. Population-based rates showed that disparities in asthma outcomes remained stable (ED visits and hospitalizations) or increased (asthma attack prevalence, deaths). In contrast, analysis with at-risk rates, which account for differences in asthma prevalence, showed that disparities in asthma outcomes remained stable (deaths), decreased (ED visits, hospitalizations), or did not exist (asthma attack prevalence).

Conclusions –
Using at-risk rates to assess racial disparities in asthma outcomes accounts for prevalence differences between black and white children, and adds another perspective to the population-based examination of asthma disparities. An at-risk rate analysis shows that among children with asthma, there is no disparity for asthma attack prevalence and that progress has been made in decreasing disparities in asthma ED visit and hospitalization rates.
