Meaningful use (MU) is a set of standards that defines criteria for electronic health records (EHR) and their effective use through activities like clinical data exchange between providers. The document discusses how hospitals can meet MU standards to qualify for incentive payments and avoid penalties by using patient referral management systems that integrate with their EHRs. Such integrated systems allow secure sharing of patient data, tracking of referral timelines and statuses, managing referral workflows, and analytics on referral patterns.
