Case Study: Lahey Health achieves 99%+ IRR for its AFib Registry with Carta Healthcare’s Lighthouse

Lahey Health boosts AFib IRR to 99.09% with Carta Healthcare

Lahey Health, an experienced healthcare provider, faced a challenge in maintaining the high data quality required for its AFib registry. Despite the diligent efforts of a skilled abstractor, manual data abstraction from complex medical records resulted in an inter-rater reliability (IRR) score of 92.29%, which was below their target. This process was frustrating for staff and threatened the credibility of their registry reporting. To address this, they turned to Carta Healthcare and its Lighthouse platform.

Carta Healthcare implemented its AI-powered Lighthouse platform, which uses a Hybrid Intelligence model. The solution combined AI to scan and surface relevant data from medical records with human expertise for validation and clinical judgment. This partnership led to an immediate and dramatic improvement, with the abstractor's average IRR score jumping to 99.09%. For Lahey Health, Carta Healthcare's solution restored abstractor confidence and ensured higher, more consistent data quality for critical registry reporting.
