Use of community health workers with inner-city children who have asthma

Health outcomes among African American and Caucasian adults following a randomized trial of an asthma education program

OBJECTIVES

Re-analysis of a randomized trial of an asthma education program designed to assess the effects of the intervention on emergency department visits, limited days of activity and asthma knowledge and beliefs separately for African American and Caucasian adults with asthma.

DESIGN

Two hundred and forty-one respondents between the ages of 18 and 70 were evaluated in two emergency departments (one inner city and one suburban location) of a large, midwestern health care system and were randomized to an intervention or control group.

RESULTS

Regardless of race, members of the intervention group showed a decrease in the number of post-intervention emergency department visits (ANOVA interaction between race and group effect p value = 0.93). The greatest decrease occurred during the first four post-intervention months. No differential effect of the asthma education intervention by race was found on the change in asthma knowledge and beliefs over the study period (ANCOVA interaction between race and group effect p value = 0.60).

CONCLUSION

This study demonstrates that post-intervention, both African American and Caucasian study participants showed a decrease in emergency department visits and an increase in asthma self-management. This finding is especially important for African Americans, who face increasing asthma mortality and morbidity.

Enhancing the role of community-health workers in research

With recognition of the importance of meeting the needs of underserved communities and the shift to more primary care-community-health workers need to be part of health teams. Community-health workers, in voluntary and salaried positions, augment the roles of professionals through outreach and community-based work and serve as liaisons between communities and institutions. This article describes the rationale for inclusion of community-health workers in research; their roles and responsibilities; and issues in their selection, training, and supervision. Examples are given from the authors' experience with interventions by nurse and community teams. Inclusion of community-health workers enriches the comprehensiveness of a holistic scientific approach to understanding health in a community.

Organisation of asthma care: what difference does it make? A systematic review of the literature

OBJECTIVES

To evaluate the effectiveness of different forms of organisation (delivery) of asthma care.

METHODS

A systematic review of the published evidence of effectiveness organisational methods of asthma management. Searches on computerised databases including Medline, CINAHL, and HELMIS, and relevant citations and letters to experts were used to identify relevant studies.

RESULTS

27 studies were identified that evaluated different organisational methods of delivery across both primary and secondary sectors, such as shared care, general practice asthma clinics, outpatient programmes, inpatient admissions policies, and the use of specialists. Only one third of the studies used a randomised controlled trial and many had small sample sizes. No conclusive evidence was found to favour any particular organisational form, although limited evidence would suggest that specialist care is better than general care and that shared care can be as effective as hospital led care.

CONCLUSIONS

There is little good published research evaluating different ways of organising the delivery of asthma care. There is need for quality research on organisational methods of delivery of asthma care that could be used to inform policy makers, in particular examining whether patients treated by healthcare professional with expertise and interest in asthma will experience better outcomes.
