Query NDC Bad Postal Code

We cross-check the postal codes we collect as part of Postal Code field collection against a list of known-good postal codes.

Template:CFE Data Integrity Checks Steps

Comparisons are done as part of vetting via NDC query NDC_Bad_Postal_Code in CFE. Steps will be:

• if the patient has Province = Manitoba:
  1. check the postal code in EPR, correct if different than ours
  2. if same as ours, check the address in EPR against Canada Post Postal Codes;
     • update patient's postal code if it was wrong or
     • make #update to Table Postal_Code_Master if postal code was correct and just not in our list
• if the patient is from any other province:
  • if the Postal Code's first letter is not for the province where the patient lives you need to check EPR or internet to put the correct Postal code
  • If the first letter is appropriate for province but triggers because it's not in the master list, then register the D_ID with Known data errors with query name "NDC_Bad_Postal_Code"
• if the patient has Province = (US or NK or OS) the query should not trigger at all

province = CF

• What if pt has Province=CF? ones should be tested as they would have postal codes, quite possibly MB ones, need to discuss

update to Table Postal_Code_Master

1. Open Table Postal_Code_Master
2. update/add code
   • you only need to fill in the fields PCode, rhaname, RHA_Acronym and town, we will eliminate the other fields.
