Union of http://www.cdc.gov/nhsn/fhirportal/dqm/ig/StructureDefinition/ach-daily-observation and http://www.cdc.gov/nhsn/fhirportal/dqm/ig/StructureDefinition/ach-daily-observation

This is the set of resources that conform to either of the profiles ACH Daily Event Observation (http://www.cdc.gov/nhsn/fhirportal/dqm/ig/StructureDefinition/ach-daily-observation) and ACH Daily Event Observation (http://www.cdc.gov/nhsn/fhirportal/dqm/ig/StructureDefinition/ach-daily-observation). E.g. what you have to deal with if you get resources conforming to one of them
