I have some concerns:
1. AIC: The updated description referring to foreign keys of various tables is inappropriate. The current description is better.

2. AIGc: The updated description should read: “Codes for a particular grouping of active ingredients. This is the 5 characters of the active ingredient code group number starting at position 3 and ending at position 7…”

3. AIGn: The updated description should read: “The AIG number is a 10 digit number that identifies products that have the same active ingredient(s) and ingredient strength(s). The AIGn is comprised of three portions:…”

4. NPN: The updated description refers to a DIN-HM. Are NPN and DIN-HM considered to be part of the same code system (2.16.840.1.113883.5.1107)? If yes, heading should be updated to NPN/DIN-HM (2.16.840.1.113883.5.1107).

I also want to point out that several years ago (back in the SCWG days), the AIGc and AIGn were rejected as pan-Canadian standards mainly due to the fact that they are (were?) auto-generated numbers with no human review. This may have changed or may no longer be relevant, but I wanted to point it out. We want to ensure that these code systems are managed/governed as code systems should be as much as possible.

We met with Daniel Buijs from Health Canada yesterday to review all of the Health Canada Code Systems - (CCDD, DIN, NPN, AIGn, AIGc, AIC). In the course of that conversation, we received updated information for the Code Systems - mainly updated email addresses, updated descriptions, and links for more information.

On Nov 13, we plan to update the metadata in the OID Registry for these code systems as follows:

The AIG number is a 10 digit number that identifies products that have the same active ingredient(s) and ingredient strength(s). The AIG is comprised of three portions:

A Drug Identification Number (DIN) is a number assigned by Health Canada to a drug product prior to being marketed in Canada. It consists of eight digits (numbers) generated by a computer system in the Submission and Information Policy Division. http://www.hc-sc.gc.ca/dhp-mps/prodpharma/databasdon/index_e.html

Updated description:
A Drug Identification Number (DIN) is a computer-generated eight digit number assigned by Health Canada to a drug product prior to being marketed in Canada. It uniquely identifies all drug products sold in a dosage form in Canada and is located on the label of prescription and over-the-counter drug products that have been evaluated and authorized for sale in Canada.

A DIN uniquely identifies the following product characteristics:
manufacturer;
product name;
active ingredient(s);
strength(s) of active ingredient(s);
pharmaceutical form; and
route of administration.

Note: The number has a leading zero
