Query Health: standards-based, cross-platform population health surveillance
Check out Jeff Klann’s recent publication in JAMIA that describes Query Health, a government-led initiative to enable distributed, secure, standards-based population health measurement. The reference implementation uses two technologies also being used within PCORnet: the i2b2 clinical data analytics warehouse and the PopMedNet secure query distribution system.
This paper demonstrates a unique way to study health information across many sites while allowing individual organizations to process queries, disclose only the minimum necessary information to answer the query, and leverage their existing information technology investment through platform-independent queries.
