I'm sure to get reamed for this post, but if so, it will only prove my point unless those doing the reaming are both accurate and precise.
I've been watching the growing eterna-thread* about the proper way to record allergies, intollerances and adverse reactions over on the HL7 Patient Care list for the past few weeks. It simply raises up the same old issues, and I think we are still no closer to having a better model for recording allergies than CCD used more than six years ago.
The issues that keep coming up have to do with the "correct" way of doing things. Which as far as I can tell, no two professionals completely agree. As far as I can tell, I am actually one step ahead of many, since I don't claim to know much, whereas others who know much more disagree quite robustly.
precision and accuracy. Current models for reporting allergies and intolerances are accurate, they just lack precision. And because they lack precision, and because healthcare professionals understand that they lack precision, the data about allergies is used appropriately.
Because we can be more precise, there is a great deal of desire to do so. Being more precise gives physicians more treatment options. It enables better use of available resources. It avoids overstatement. It allows for a more precise assessment.
But, in so doing, it requires others to act with a greater degree of precision as well. I'm not so happy about providing physicians with a very precise statement of my allergies and intolerances if it means that they become paralyzed trying to understand it, or are unable to make use of it with the degree of precision and accuracy necessary.
Where we are now enables us to make a generalized statement about allergy and intolerances, and invites further exploration by the healthcare provider when greater precision is necessary. This seems to be the safest path forward. But what do I know? I'm not an expert. I just have to implement what they tell me. Once they all agree on what that is...
