Overview

We maintain current observations for each patient in their #current_observation_set. CurrentObservationSet#values is a hash (stored as jsonb) where the OBX code is the key and the result value and observation date are themselves a hash. So values looks like this {

"HGB": {
  "result": 123,
  observed_at: "2017-12-12 12:12:12"
},
"CRE": {
  ...
}

} and always contains the very latest pathology result for any code. We store all incoming OBX codes, not just a restricted list. Legacy data might only contain a subset of codes, so #values should not be relied on to cover current observations for the patients entire history, just key ones. When displaying or using a patient’s current_observation_set the consuming code must filter out the codes it wants.
