8. Bacterial Growth Observation - Healthedata1/OO-on-FHIR-Micro-Profile GitHub Wiki

This Profile on Observation defines the subjective growth observations for a culture.

The degree of bacterial colony growth is often reported by laboratories. They may also Quantify the bacteria using some other method which would be covered by the [Count Observation Profile](9. Colony Count Observation).

Based on DAF-Core/US-Core plus additional USlab (LRI) and US-Core Micro Report constraints (in italics):

Each Observation must include:

  1. a status
  2. a category code of ‘laboratory’
  • micro category code as translation
  1. a LOINC code, which tells you what is being measured
  2. performing organization
  3. a patient
  4. a coded result value or a reason if there are no values

Each Gram stain Observation must include: must support:

(stuff from LRI OBX and OBR)

  1. an identifier (Filler/Placer) - Discuss whether this is a must support - not an LRI requirement
  2. a time indicating when the specimen was collected
  3. a time indicating when the measurement was reported
  4. the specimen
  5. a specimen rejection reason This is really a data absent reason and should go there instead of an extension on Obs - consider a DAR profile

(note: the LRI requirement for AOE vs results category is not needed for this profile since is implicitly a result profile)

Terminology considerations ( note need help from community to work these out)

This profile uses the same set of codes that are found in the microreport profile

For Observation.valueCodeableConcept - extensible binding to SNOMED CT qualifier codes for 'Heavy Growth', 'Moderate Growth' and 'Scanty Growth'.
