About patients urine output data

Prerequisites

Hi, we are looking for urine output data from OUTPUTEVENTS table of MIMIC III, especially output volumn (mL or ml/kg/hr).
We figure out that some patients has double data in the same CHARTTIME.
For example, equal SUBJECT_ID, equal HADM_ID, equal ICUSTAYS, equal CHARTTIME and equal LABEL(This is name of ITEMID) has different value and CGID in the following figure. What happen in this data?

Please describe these kind of data are loaded in the table.

• Put an X between the brackets on this line if you have done all of the following:
  • Checked the online documentation: https://mimic.mit.edu/
  • Checked that your issue isn't already addressed: https://github.com/MIT-LCP/mimic-code/issues?utf8=%E2%9C%93&q=

Description

Description of the issue, including:

• what you have tried
• references to similar issues
• queries demonstrating your question (if applicable)

Start with the OUTPUTEVENTS table and the MIMIC documentation linked in the issue. Investigate why rows sharing SUBJECT_ID, HADM_ID, ICUSTAY_ID, CHARTTIME, and LABEL can have different VALUE and CGID fields; done means documenting the meaning of these duplicate-looking records and their urine-output units.
