Collaborative Integration of Community Health Workers in Hospitals and Health Centers to Reduce Pediatric Asthma Disparities: A Quality Improvement Program Evaluation.

ABSTRACT

To address pediatric asthma disparities on the South Side of Chicago, a community health worker (CHW) home visiting intervention was implemented collaboratively by academic institutions and community based health centers. This evaluation assessed the effectiveness of this longitudinal quality improvement CHW intervention in reducing asthma morbidity and healthcare utilization. All patients aged 2-18 who met the high-risk clinical criteria in outpatient settings or those who visited the ED due to asthma were offered the program. A within-subject study design analyzed asthma morbidity and healthcare utilization at baseline and follow-up. Multivariable mixed-effects regression models, adjusted for baseline demographic and asthma characteristics, were used to assess changes over time. Among 123 patients, the average age was 8.8 (4.4) years, and 89.3% were non-Hispanic black. Significant reductions were observed in the average daytime symptoms days (baseline 4.1 days and follow-up 1.6 days), night-time symptoms days (3.0 days and 1.2 days), and days requiring rescue medication (4.1 days and 1.6 days) in the past two weeks (all p < 0.001). The average number of emergency department visits decreased from 0.92 one year before to 0.44 one year after program participation, a 52% reduction (p < 0.001). No significant difference was found in hospital admissions. These results support the use of a collaborative approach to implement the CHW home visiting program as part of standard care for pediatric asthma patients in urban settings. This approach has the potential to reduce asthma disparities and underscores the valuable role of CHWs within the clinical care team.
