8. Why is Patient Matching Such a Challenge?
• Technical
– Heterogeneous technologies and vendors
– Data exchange latency (e.g. timeouts, lack of consent/authorization)
• Data
– Data quality, completeness, consistency
– Different default values (“John Doe”)
• Policy and legal
– Different legal jurisdictions and requirements (such as for minors)
– Different patient matching rules
– Consent, security, sensitive data sharing
• Process
– Different QA and human and system workflows (latency, variations, definitions, etc.)
– Organizational size, resource allocation, project timelines, commitment, skill levels
– Change management
• The result:
– Match rates ACROSS organizations are frequently unacceptable
– 10% to 30% in several cases
