Topic: Use of Observation.category

I'm puzzled by the values in Observation Category.
Some codes are about the type of information : e.g. social-history and vital-signs, others are about the method of observation: e.g. imaging and laboratory.
Richard Townley-O'Neill (Mar 03 2022 at 05:41):
1/ There is no category for calculated observations, such as Apgar score and BMI. ( BMI is also a vital sign.) Is calculation not an interesting feature of observation, so Apgar and BMI are both of category exam?
Richard Townley-O'Neill (Mar 03 2022 at 05:42):
2/ The name 'survey' suggests it is primarily for info from things like questionnaires, such as those completed by a patient, e.g. last menstrual period, parity. Is it? If so the examples are wrong. If not, the code and display are misleading. Maybe call it something like 'formal-assessment'.
Richard Townley-O'Neill (Mar 03 2022 at 05:42):
3/ I suggest that we add a category for obstetric history - observations about a patient's previous and current pregnancies, including the childbirth and postpartum periods.
Richard Townley-O'Neill (Mar 03 2022 at 05:42):
4/ How would estimated gestational age be categorised. It can be calculated from LMP (maybe an exam?), derived from comparing ultrasound observations to a table of normal values (imaging?), assessed from an observation of the abdomen etc. (exam?), and others. What is the category when the value is produced by a clinician assessing and reconciling estimates made using different methods?

What is the intended scope of the category 'survey'. Its name suggests it is primarily for info from things like questionnaires, such as those completed by a patient, e.g. last menstrual period, parity. Is it?
If so the examples seem wrong.
If not, the code and display are misleading. Maybe call it something like 'formal-assessment'.

the definition is here: https://www.hl7.org/fhir/codesystem-observation-category.html#observation-category-survey
Eric Haas (Mar 17 2022 at 23:50):
e.g. survey, form, questionnaire, assessment.
Eric Haas (Mar 17 2022 at 23:51):
Although it is clear to me ( I wrote it :-)) instead of changing the name how about suggesting a clearer definition.

@Eric Haas
So the intended scope includes all of
- assessment tools (e.g. Apgar Scores, Montreal Cognitive Assessment (MoCA),
- questionnaires and surveys (e.g. patient experience survey),
- forms (e.g. patient medical history on first visit to a clinical practice)
Richard Townley-O'Neill (Apr 05 2022 at 07:02):
maybe change
| Survey | Assessment tool/survey instrument observations (e.g., Apgar Scores, Montreal Cognitive Assessment (MoCA)). |
to
| Survey | Observations from survey instruments (e.g. patient experience surveys), questionnaires, forms (e.g. patient admission forms) and assessment tools (e.g. Apgar Scores, Montreal Cognitive Assessment (MoCA)). |
