A CMS Inpatient_Claims data record has a ADMTNG_ICD9_DGNS_CD field and also ICD9_DGNS_CD_1 – ICD9_DGNS_CD_10, ICD9_PRCDR_CD_1 – ICD9_PRCDR_CD_6.
A concept in the vocabulary exists for Primary Diagnosic: 38000199òInpatient header - primaryò1òCondition Occurrence Type but it is not used in the ETL. All inpatient records are hardcoded to a CONDITION_TYPE_CONCEPT_ID of 38000200 which is Inpatient header - 1st position and similar 38000230 for outpatient. This happens also in the procedure_occurrence OMOP table.
I believe it means that data is lost in the translation since there are 17 possible codes coming from the Medicare data but the data is mapped into only 4.
In my case, I am trying to replicate a study called Surgeon Scorecard against an OMOP data format that used the Medicare CMS ADMTNG_ICD9_DGNS_CD field as a way to find particular surgeries and calculate a Surgeon complication rate.
Here are the counts of the concept_id's in the converted SynPuf data.
CONDITION_TYPE_CONCEPT_ID,COUNT,DESCRIPTION
38000230,280864910,Outpatient header - 1st position
38000200,8317475,Inpatient header - 1st position
PROCEDURE_TYPE_CONCEPT_ID,COUNT,DESCRIPTION
38000269,275176949,Outpatient header - 1st position
38000251,3592580,Inpatient header - 1st position
Suggest to slowly fix things to follow pep8 conventions as we slowly go spelunking.
We can worry about variable names being in all caps until we have the unit tests from #12 all created.
visit_occurrences aren't yet generated by the ETL.
This is the most complicated table to ETL. Employees of @outcomesinsights (@claire-oi, @marc-outins, @jenniferduryea) are standing by to answer questions about this part of the ETL should you have any.
I run script from unm-improvements branch and found error
Script requires ".csv.srt" files. What is it? I disabled it in this row.
Hello,
I download the synpuf dataset and noticed that there is something off with the care_site table records so I'd like to verify ( ftp://ftp.ohdsi.org/synpuf/care_site.csv.gz).
Is it expected that location_id is null for all care_site records?
Is there a way to associate each of the care_site records to specific location_id(s)?
Thanks,
Laurence
On the CMS website, the 2010 Beneficiary Summary file of sample 1 has an incorrect name. It is called DE1_0_2010_Beneficiary_Summary_File_Sample_20.zip
, but the Python script expects it to be called DE1_0_2010_Beneficiary_Summary_File_Sample_1.zip
(which would make more sense since it is sample number 1, not 20).
Because of this, the Python script throws an error when trying to download the first sample.
A simple workaround is:
It would be nice if the script was modified to deal with this, but I suspect not many people will be working on this repo anymore.

Also, tried to register and get licensed on UMLS (by following this). But even I provided the username and password, I still have the same issue.
Any idea of what's going on? How to solve the issue?
This doesn't support RIF, does it? Is there a repository nearby that does? I don't see one.
context: I'm working on CMS RIF to i2b2 (https://github.com/kumc-bmi/grouse) and considering going via OMOP.
The .env.example files are missing the required entry for BASE_ETL_CONTROL_DIRECTORY. This causes the etl to fail until it has been added
The original author suggested that we should add some unit tests to the ETL. Assuming that we don't find #11 to be an efficient/sufficient means of testing the ETL, I agree we should have some unit tests.
I run script from unm-improvements branch and found error

'issue' posted as new topic in the forum with reference to this git issue
The ETL is generating observation periods, but according to the original author, they seem to be incorrect. I have no further details.
I wrote an R script for upload the Synpuf data into CDM v5.2.2. There are some new conventions for CDMs that the ETL script doesn't yet follow. My script fixes those, but it would be nicer if they were moved into the ETL script. These are the issues I found:
DATE
fields should also get a DATE_TIME
field, by just copying the date, and setting time to midnightDRUG_EXPOSURE_END_DATE
field must be populated. This can simply be done by adding the DAYS_SUPPLY
to the DRUG_EXPOSURE_START_DATE
.I guess 1 is harder, but 2 and 3 are pretty trivial.
For even newer versions I think we need to start using the new TYPE_CONCEPT_ID
and STATUS_CONCEPT_ID
codes and fields.
Hello!
Where I can find omop_vocab_xref_0723.txt?. Here is a refenrence
The command CMS_SynPuf_ETL_CDM_v5.py was CMS_SynPUF_ETL_CDM_v5.py in the python-etl README file which caused some confusion when trying to cut and paste commands from it.
According to the original author, this is an issue that needs to be addressed in the ETL. I have no further details.
In 2015, Medicare switched over to using icd10 coding though a new SynPUF has not been provided. Is there value in having a data set that uses icd10 codes instead of icd9?
With some code I have written, I could pretty easily convert the omop Synpuf data from icd9 to icd10 and then shift the dates. icd9 to icd10 can be one to many so the code could select a random icd10 code from the group.
Would there be interest in this?
I can see the need for 3 datasets:
-icd9 code dataset for pre 2015 data (direct convertion of SynPUF)
-icd10 code dataset for post 2015 data
-data the includes mixed icd9 and icd10 data based on the years the Medicare switched.
Goal is to allow researchers to test their code prior to getting the real data.
The original author used print statements to log the progress of the ETL and is hoping that someone else can replace that approach with whatever Python uses as a standard for generating logs.
Inside CMS VRDC, we are not able to run Python. We initiated a project that ports this ETL to pure SQL that can run in SAS (SAS SQL flavor :-( )
measurements aren't yet generated by the ETL.
Hi,
I tried to download the processed data from your FTP link and the Google drive but neither of them are working. Is there any other option to get the data ?
Thanks.
Paul L
I think I see a copy of the SynPUF out on Postgres Public. If this is truly a build then the CDM_SOURCE.VOCABULARY_VERSION would be more informative if you pulled this information off the Vocab you ran off of:
SELECT VOCABULARY_VERSION
FROM vocabulary
WHERE VOCABULARY_ID = 'None';
This way you know exactly which Vocab was used in the build.
README.md says "The processed data can be retrieved from ftp://ftp.ohdsi.org/synpuf"
It appears ftp://ftp.ohdsi.org/synpuf is inaccessible; Is the FTP server down?
In CMS synthetic data, the Beneficiary ID, 'DESYNPUF_ID', is of type String (technically hexadecimal).
When using Spark or other big data engines, it is generally easier to use this existing unique ID than to compute our own incremental ID, as that would require computing all IDs on a single node in the cluster (each id needs the value of the previous one). That would not allow parallelization of the processing.
Is there any particular reason for making IDs integer, instead of string?
Thanks!
Hi All,
I am executing the step 5 python ETL script and getting the below error.
when I tested the script with test data, it executed successfully but when I am running this on cSynpuf claims data I am having this issue.
I am running this on Intel i7-6600U CPU 2.81 GHz processor and 12 GB RAM. additionally, i have more than 150 GB space free on the drive.
Please let me know if someone has come across this issue while their implementation process and steps to resolve this.
Thanks in advance for your help.
Thanks,
Ratan
I am trying to download the downloadable OMOP CDMv5.2 version; however, the file seems not available to the public. Please modify the permissions to allow for public access

I'm working on setting up a local copy of the OMOP SynPUF for testing and noticed that the MD5s show on the readme at https://github.com/OHDSI/ETL-CMS/blob/master/python_etl/README.md don't match the md5 of the files. This file on the ftp site matches what I get locally:
ftp://ftp.ohdsi.org/synpuf/1.0.1/md5sums.txt
The specific mismatches are (shown with what appears to be the correct md5 hash):
da0e310e7313e7b4894d1b1a15aee674 synpuf_1.zip
c1529ea8b4e4e092d0cdd2600ea61c75 visit_occurrence.csv.gz
The readme appears to have the old md5sums from ftp://ftp.ohdsi.org/synpuf/1.0.0/md5sums.txt for those two files.
I run script from unm-improvements branch and found error
Condition_occurrence table has int condition_source_concept_id field. But script generates string value in this position (value has letters) of result csv-file. Source csv-file has no letters in condition_source_concept_id position
The original ETL was written with a few lines of code that only run under Python 2.x (mostly print statements that should be eliminated in #8).
In my mind, the ETL should be running under Python 3.x, seeing as 3.x has gained relatively widespread adoption at this point and I don't believe there are any library-dependencies that require us to stick with 2.x
We should gather a handful of rows from each source file and hand-convert those rows into CDMv5, then feed those rows through our ETL and verify it generates the exact same rows. This will serve to test that our ETL process is properly functioning.
As we hit odd rows in the raw data, we can add them to our set of test rows and verify that we're covering all the weird edge-cases we discover during the implementation of the ETL.
Hey folks,
First off, thank you for this resource connecting the synthetic dataset to OMOP, this is very helpful for me to evaluate how OMOP can benefit my work. This has saved me a ton of time.
Below is some unsolicited feedback after using the unm-improvements
branch to generate sample patient data for my local OMOP CDM instance. I was referred to here from this discussion.
get_synpuf_files.py
utility was confusing. The README was correct, so doing python output 4 20
worked, but the feedback from the tool was telling me otherwise: output
was the INPUT_DIRECTORY
, 4
was the OUTPUT_DIRECTORY
, and 20
was the SAMPLE_RANGE
.get_synpuf_files.py
is written in python3, but CMS_SynPuf_ETL_CDM_v5.py
is python2. It seems like you folks are thinking about which to use, but to me, consistency within a single repo is the most important trait.omop_vocab_xref_0723.txt
, so I ended up commenting out the section that builds the mapping xref.I'm sure there's lots of internal discussion over on your end, but I would suggest possibly the following to make this really useful to the general public:
Thanks again! Super helpful.

CDM 6.x has introduced some key changes to the omop CDM, that will require updating the ETL logic. New changes includes changes to cost table, payer_plan_period, visit_detail, location, location_history.
It would be nice to work together to create a new version of the ETL logic

observations aren't yet generated by the ETL.
According to the original author, the condition/procedure_type_concept_ids are not correctly generated by the ETL.
The Inpatient visit type is applied to all visit occurrences (9201). Dropping this here as a reminder to myself or anyone else to make the quick fix. Should also update the pre-compiled data files based on the fix.

Importing drug_era fails: ERROR: invalid input syntax for integer: "2008-02-27"

Hi,
I followed the steps in documentations to load data in postgres. but in part e of step 7, when I wanna load data using the sql file, I see the following error:
psql:load_CDMv5_vocabulary.sql:26: ERROR: extra data after last expected column
CONTEXT: COPY drug_strength, line 2: "42478670 913782 2 8576 2
0150817 20991231
I got vocabularies from OMOP Vocabulary Web Site and did not change it. I couldn't find the problem. can any one tell me what I am doing wrong.
As part of the documentation we generate for the ETL, we should include some hardware requirements (if we hit any limits) along with approximate benchmarks for several of the hardware setups we run the ETL on.
File to update : https://github.com/OHDSI/ETL-CMS/blob/master/python_etl/README.md#3-download-cdmv5-vocabulary-files
Currently command to append CPT4 is:
java -jar cpt4.jar
It should be:

Hi,
I download the SynPUF data in CMS.
However, I can't download the file [DE1.0 Sample 1 2010 Beneficiary Summary File (ZIP)].
This file is linked to sample 20 not sample 1.
