“Pull” technology is used in scenarios where an HIO provides a record locator service (RLS) that requires a centralized index of all patients (Enterprise Master Person Index or EMPI) collected from HIO participants and a cross-reference to each participating organization’s medical record number (MRN) is assembled using advanced demographic matching techniques and is stored in the EMPI.
A provider searches the HIO EMPI using either the patient’s demographic information or the provider’s previously assigned patient identifier.
Government-issued identification should be the standard. There is a lack of data standards addressing accurate and complete data capture and data matching for patient identification.
And the standards that do exist are limited in scope and adherence is suboptimal.

Data trading partnerships between providers may dictate the content and format of the HL7 message.
This incompatibility compromises healthcare’s ability to achieve truly successful interoperability.
Exchange relies entirely upon demographic information contained in the individual person’s record to initially match their clinical information amongst multiple provider organizations.
However these protocols and standards are not routinely adopted or consistently implemented by vendors, enterprises, or HIOs.
Organizations rely instead on data being captured in compliance with older HL7 standards.
It urges industry stakeholders to recognize that now is a critical time to address accuracy in patient identification systems.
