Physiological Date

@Burke
    Someplace on the wiki (order? obs?) I was reading something you wrote saying that for lab results, the obs date should be the "physiological date."  By that, do you mean the date of specimen collection (as opposed to the date the test was actually run by the lab)?

Re: Physiological Date

Roger,

I believe I mentioned physiologic time in a recent e-mail message.  There are many times that can be associated with an observation, especially an observation of a blood test – e.g., time order given, time order received, time blood drawn, time specimen arrived, time result calculated, time result reported, etc.  There are workflows that could justify using any of these times or adding new ones, but the most broadly & clinically useful time for an observation is the point in time that it was true for the patient, which is sometimes referred to as the physiologic time.  For a blood test, it would be the time the blood was drawn.  For a questionnaire, it would be the time that the question was answered.  In OpenMRS, our assumption is that the obs_datetime will be a close approximation to the physiologic time.
