Description
This concept set contains a single code pertaining to gestational age. There was an interest in examining the effect of gestational age/pre-term birth across a number of PRESERVE sub-studies or manuscripts. However, data quality analyses indicated high missingness for this clinical concept. This was not a high priority variable for PRESERVE. Given these considerations, gestational age is not included in final analyses. This LOINC code was selected by the PRESERVE Coordinating Center as the code that PRESERVE sites should use to represent gestational age in their PRESERVE PCORnet CDM submissions. PRESERVE sites were instructed to represent gestational age information with this code in the obs_gen table (obsgen_type = ‘LC’, obsgen_code = ''18185-9", obsgen_result_unit = ‘wk’, obsgen_result_num = weeks and fraction of week). Representing gestational age exclusively with this LOINC code is specific to the PRESERVE study. It is anticipated that the main PEDSnet and PCORnet databases use a greater range of codes.
Note: This concept set should not be used in non-PRESERVE studies without substantial updates.
