We don't have one at the moment but if you highlight which columns have codes you are interested in we can ask the right people and add it to the documentation.

Thanks for your reply. Here are some of the columns I have questions on:

• In the ApachePredVar Table: the columns admitsource, dischargelocation, and amilocation
• In the Hospital Table: the column teachingstatus
  I also have a question regarding how identification numbers are used. I understand how they are used for the column patientUnitStayid but in other columns it isn't as clear. For instance, for the column “diagnosisid” is one ID number given for a specific diagnosis so that if you were looking for patients with “x” diagnosis you could search the database for that specific diagnosisid?

The table "id" columns are just used to ensure uniqueness of rows. They have no meaning. You'll find diagnosisid is unique to every row. I'll get back to you on the others.

You can generate the mapping for admitsource values by linking the apachepredvar table to the patient table:

select distinct a.admitsource, p.unitadmitsource
from `physionet-data.eicu_crd_demo.apachepredvar` a 
left join `physionet-data.eicu_crd_demo.patient` p
on a.patientunitstayid = p.patientunitstayid
order by admitsource;

Row    admitsource    unitadmitsource     
1    -1         
2    1    Operating Room     
3    2    Recovery Room     
4    4    Floor     
5    4    Step-Down Unit (SDU)     
6    4    ICU to SDU     
7    5    Other ICU     
8    6    Other Hospital     
9    7    Direct Admit     
10    8    Emergency Department

I also have the same question on what are the numbers contained in "admitsource" under ApachePredVar represents. These are so important that can change the model completely.
Thanks in advance.

And it seems to me that the number of patients in each group mapped to the patient table does not make much sense, esp. there is no.3 in admitsource that is not correlated to any group. in unitadmitsource.
