Existing Wording: In observations, SFCU is used to describe the specific contexts used in the observation. For example, the computation of glomerular filtration rate (GFR) based on blood chemistry uses formulas that are different for “male” and “female”. The SFCU for the GFR report can indicate which formula was used in the computation of that result. The expectation is that the patient level SFCU is the default value used in all observations in a report and have an individual SFCU for individual observations when that observation was performed using a different SFCU. The Gender Harmony model does not cover the description of individual observations, but the SFCU attribute can be used. New Wording: The SPCU, when used for a specific observation, describes a context that clarifies the settings or reference ranges for the observation. For example, the computation of glomerular filtration rate (GFR) based on blood chemistry may use formulas that are different for “male” and “female”. The SPCU for the GFR report can indicate which formula should be used in the computation of that result. In cases where there is a patient level SPCU, the patient level value can be used as a default (any specific use) value unless a specific SPCU for that observation has been specified, in which case, the specified SPCU should apply. The Gender Harmony model does not cover the description of the use of SPCU in type of observation, but the approach for each is the same.
