Translation squared: improving asthma care for high-disparity populations through a safety net practice-based...

Area of Science:

• Public Health
• Primary Care Medicine
• Health Disparities Research

Background:

• Asthma care guideline adherence is crucial for managing the condition, especially in high-disparity populations.
• Safety net health centers face challenges in implementing evidence-based practices.
• Previous efforts focused on guideline dissemination alone have shown limited success.

Purpose of the Study:

• To evaluate an intervention aimed at increasing adherence to national asthma care guidelines.
• To assess the intervention's effectiveness in primary care safety net health centers serving high-disparity populations.

Main Methods:

• A group-randomized controlled trial was conducted across federally funded community health centers in eight southeastern states.
• The intervention included asthma care resources, staff training, and practice-level system change tools.
• Control sites received only national asthma guidelines; chart reviews assessed practitioner compliance.

Main Results:

• Clinicians in intervention sites demonstrated significantly greater improvement in guideline compliance compared to control sites (p < 0.01).
• Despite improvements, post-intervention compliance with asthma care guidelines remained suboptimal.
• The multifaceted intervention proved effective even in resource-limited safety net settings.

Conclusions:

• Guideline dissemination alone is insufficient for improving asthma care.
• A comprehensive approach combining resources, training, and practice change tools enhances guideline adherence.
• This intervention model shows promise for improving care in underserved populations within safety net health centers.
