Re: [gpc-informatics] #551: next-D labs for cohort selection: fasting glucose, HbA1c

I agree with Phillip. Clinically, the date/time reported for a lab test is always when the patient had blood drawn or gave the sample. THAT is when the patient was 'tested'. Nebraska records all lab test observation_facts with START_DATE as date/time specimen was taken. We record order time

Re: [gpc-informatics] #551: next-D labs for cohort selection: fasting glucose, HbA1c

*Dan:* It is important to be clear what each site use under "start_date". Especially for cases when ORDER_DATE is different from SPECIMEN_TAKEN_DATE. I appreciate, Dan if you could gather this info. It is important to be on the same terms when collecting data to the table 1. *Phillip:* I agree that

Re: [gpc-informatics] #551: next-D labs for cohort selection: fasting glucose, HbA1c

I'd recommend using the SPECIMEN_TAKEN_DATE/TIME for the start_date of a lab. I believe it is the more clinically correct time as the results of labs can sometimes take days to return. We use the specimen time, followed by the result time, I believe. For the PCORI CDM, I plan on putting all

RE: [gpc-informatics] #551: next-D labs for cohort selection: fasting glucose, HbA1c

Reviewing the HERON ETL code, I see it does populate the i2b2 start_date for labs from Epic's result_time, which looks more like RESULT_DATE. I see that our code to build the PCORNet LAB_RESULT_CM.LAB_ORDER_DATE (PCORNetLoader_ora.sql#L1407

Re: [gpc-informatics] #551: next-D labs for cohort selection: fasting glucose, HbA1c

Dan, great job! Meanwhile, could you please clarify actual meaning of "start_date" in i2b2? Is it more like "LAB_OERDER_DATE" (when lab was ordered), "SPECIMEN_DATE" (when specimen was taken), "RESULT_DATE" (when results became available)? Alona. On Tue, Jan 24, 2017 at 4:06 PM, GPC Informatics
