* Julie has found inconsistencies between PCs for consecutive admissions. We know that PCs that come in from Cognos are often found to change in EMR during the admission, and (some? all?) collectors change them to the final PC as found in EMR. We need to decide how we want to define PCs with regard to those changes to make sure we provide data that is consistent ''and'' defined in the way that is most useful for our reporting purposes.
We could define Postal Code as "on admission" or "on discharge". That would depend how we plan to use it. Do we care where someone came from, or do we use this with regard to discharge difficulties? If someone comes from Ashern, is in hospital for 3 months, and moves their home address to a care home in Winnipeg before discharge… what do we want to have in our DB? The original Cognos PC would be easiest and most consistent. But then we may not be able to use the PC for discharge based concepts. Or maybe we can, since the number of affected records might be small. I wonder if we should do a short term project where collectors enter when a PC changes from original Cognos import before discharge. A count would tell us how common this situation is, and help us decide how to proceed. It could be just documenting that we use initial PC and have found that a percentage of ??? changes during the hospital stay. Or it could be a change in definition. 
For discussion at task meeting, but please add observations here if you have any. [[User:Ttenbergen|Ttenbergen]] 10:05, 2023 November 5 (CST)
* My thoughts - we can revise our Postal Code definition as 'on admission' onwards and if the user who asks it does not agree with ours, then the user can choose to get it from somewhere else.  This data is very seldom asked so let us not add more work on it.  Let us just standardize it or  make it consistent  by using one source of data and decide which source to use  COGNOS or EMR? --[[User:JMojica|JMojica]] 09:35, 2023 November 6 (CST)

The patient's postal code.

  • SMW

Legacy implementation right in the table

  • Cargo


  • Categories
  • Forms


The Postal_Code field can be edited in the Dispo tab. A postal code is collected for all patients admitted to a hospital within the WRHA. The postal code collected is from the address that a person permanently resides in any Province in Canada.


Collection Instruction

Enter the Postal code

  • no space
  • upper case letters
  • example only: X0X0X0

When the postal code is not available (e.g. John or Jane Doe patient or chart doesn't have postal code) enter "N/A" or click the "N/A" button to enter it for you.

Don't trust Postal Codes from Cognos

Don't trust the postal codes that come from Cognos2, we know that the codes in the data dump can be wrong anc change from day to day, and have been unable get a fix from Decision Support Services. Confirm Postal Codes in EPR and enter the code from EPR if different from Cognos.

Special Cases

Homeless with proxy address

If you have a homeless person admitted who lists their address as Siloam Mission or the Salvation Army/Booth's Place, do NOT use that place's postal code as provided, use N/A for postal code

Code "couch surfers" as "N/A".

Institutionalized patients

For institutionalized patients (e.g. Prison / Jail / Correctional Institution inmates, care homes), use the institution's postal code.

Out-of-Country patients

Our cross checks would flag the format of out-of-country postal codes, so enter "N/A" for these.

International Students

If they have an address in the Province, enter it, otherwise treat them as #Out-of-Country patients.

Relationship between Province, PHIN and Postal code

When collecting Postal Code, PHIN number and Province, think about the relationship of this information when you are collecting it.

  • if patient has a MB PHIN number, then Province code should be MB and the postal code should be for MB (MB postal codes start with an "R").
  • if Province code is not MB then the postal code should not be a MB postal code. Enter "not applicable" or the out of province postal code if available, and also, there should not be a PHIN number.

Data Use

Postal Codes are used group patients geographically for purposes such as:

  • distribution of patients by MB RHAs outside of Winnipeg
  • linking to Stats Canada for socioeconomic stratification of population by geographic area
  • cross-checking our data's Province field for out-of-province patients

table Postal_Code_Master

This is the table that postal codes get checked again. It includes the MB RHA that a postal code is affiliated with. For the MB component we imported a version provided by Marc Silva to p:Julie Mojica 2016-09-08. The country-wide component was based on an older table I think we go it from Stats Can.
