Targeting Communities for Radiology Quality Improvement: Beyond Socioeconomic Strata Alone

Using a potential adherence improvement index (PAII) to target radiology quality interventions instead of deprivation alone captured communities with much lower adherence (41% vs 74%) and only 20% overlap, potentially improving equity and efficiency.

• Secondary analysis of recommendation for additional imaging (RAI) adherence from 545 communities at a large academic medical center (2019-2021).
• Highest PAII quintile communities had 41% adherence vs 74% in highest area deprivation index (ADI) quintile, with only 20% overlap; mean PAII was 1.53 vs 0.49 (p<0.001).
• Geospatial mapping and plots identified optimal target communities across resource thresholds, with higher ADI variance in the highest PAII quintile (F=2.12, p<0.001).
