Purpose

This WS allows to create Specimen entity by employees without submitting Encounter Data Package.

Key points

1. Only authenticated and authorized employee with appropriate scope can create a Specimen.

2. Request should be signed with DS.

3. The specimen is created asynchronously

4. The specimen can be created both for persons and for prepersons.

Specification

Apiary

Authorization

• Verify the validity of access token

  • in case of error - return 401 (“Invalid access token”) in case of validation fails

• Verify that token is not expired

  • in case of error - return 401 (“Invalid access token”)

• Check user and client scopes in order to perform this action (scope = 'specimen:write')

  • return 403 (“Your scope does not allow to access this resource. Missing allowances: specimen:write”) in case of invalid scope(s)

• If BLOCK_UNVERIFIED_PARTY_USERS is true, then check party's data match following condition: verification_status != NOT_VERIFIED or (verification_status = NOT_VERIFIED and updated_at > current_date - UNVERIFIED_PARTY_PERIOD_DAYS_ALLOWED):

• If BLOCK_DECEASED_PARTY_USERS is true, check that party is not deceased (party_verification record does not equal to: dracs_death_verification_status = VERIFIED and dracs_death_verification_reason = MANUAL_CONFIRMED):

  • in case of error - return 403 ("Access denied. Party is deceased")

Validate legal entity

• Extract client_id from token

Service logic

1. Save signed content to media storage, in the bucket pointed in MEDIA_STORAGE_SPECIMEN_BUCKET chart parameter

2. Generate accession_identifier number:

   1. Generate requisition number (see Human readable requisition number) based on the specimen id. Note: requisition number should be unique for each specimen and should not match with number of another entities. So, if generated number match to existing in DB - it should be regenerated

   2. Encode and set it into $.accession_identifier attribute

3. Set display_value for:

   1. registered_by attribute

   2. managing_organization attribute

   3. collection.collector attribute, only if type is employee (not patient)

4. Set context, received_time, status_reason, collection.procedure to null

5. Set subject with hashed mpi identifier

6. Save data to specimens collection in DB according to https://e-health-ua.atlassian.net/wiki/spaces/SPECIMEN/pages/17548214286

7. Save link from media storage to the $.signed_content_links field in specimens collection

8. Create job and return it’s id.
