We want to discuss and come to an agreement about mapping rules for drugs, devices and procedures related to oxygen. It seems we don’t have a clear convention currently:
- some concepts being Devices or Procedures already have additional mapping to Drug oxygen ingredient;
- some other Procedures are mapped only to Oxygen therapy Procedure;
- and most Devices - not mapped at all.
It creates ambiguity. Let’s make a clear definition for the following group of concepts ETLer can meet in real-world data, including claims:
- Devices containing oxygen by itself: oxygen tank 1 L, oxygen container, oxygen cylinder, liquid oxygen reservoir, etc.
- Devices with obvious indication to oxygen support: oxygenator, oxygen enricher, oxygen tent, liquid oxygen cold evaporator, etc.
- Devices where oxygen usage is implied, but description allows another interpretation: oxygen mask/hose/adaptor, ventilator replacement parts.
- Procedures with obvious indication to oxygen support: ECMO, hyperbaric oxygenation, oxygen inhalation, oxygen therapy, etc.
- Procedures where oxygen use is only implied: artificial respiration, lung ventilation, assisted circulation.
- Observations: guidance for home oxygen therapy, home oxygen therapy education, oxygen therapy guidance management.
Materials from group 1 don’t seem to be supplied empty (without oxygen in there) and may get additional mapping to Drug oxygen ingredient. Maybe the same is true for group 2, while group 3 is tricky and doesn’t deserve mapping.
Observations from group 6 tend to be used for additional coding only and don’t need further mapping.
