Examples of How LOINC Fails Nursing

The way LOINC encodes medical data does not support nursing well. The two mental models are only partially compatible.

In particular, patient assessments are something nurses do many times on every shift. The data that is thus generated needs to be captured in the EHR. To store a nurse's observation in an EHR, the observation must be encoded. Often, there is no appropriate encoding mechanism in LOINC. Here are some examples.

What can be done to solve these problems? What must we do to make EHRs more nursing-supportive? I do have some ideas about this and look forward to discussions with interested parties, especially the Regenstrief folks who are the keepers of the LOINC standard.
