I am doing research to predict frailty using all covariate data.
So I have to create all covariate data(condition occurrence, drug, …) using FeatureExtraction package.
And I want to remove chief complaint condition concept id.
I refered to the vignette ‘Creating custom covariate builders’ on FeatureExtraction package github to remove condition chief complaint concept id.
However I had to create all covariate data, but only condition occurrence covariate data.
And I added a conditional sentence ‘where condition_type_concept_id != 42894222(chief complaint concept id)’ to ‘FeatureExtraction/sql/sql_serverDomainConcept.sql’.
However ‘java.lang.nullpointerexception’ error arised.
How to remove the chief complaint from condition occurrence covariate data?
And can I apply the solution to procedure covariate data?
