Purpose

The service is designed to uploading new medication registry. The process uses the jabba service. Upon execution of the request, a job is created, on the basis of which tasks are created. Each task is one request to create entity from registry.

Key points

1. NHS admin user download file with fields according to its structure.

2. File should be in .csv format.

3. Full medication registry input data for GraphQL mutatiuon should be in .csv format and with escaped symbols (i.e. quotes, new lines - " as \"; new line replaced as \r\n ). Please note that UI of NHS Admin panel converts csv file to appropriate GraphQL input.

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 scopes in order to perform this action (scope = 'medication_registry:write')

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

Validate request

1. Validate request

   1. Check that request using schema

      1. Return 422 with the list of validation errors in case validation fails.

   2. Check that registerType = 'FULL_MEDICATIONS_REGISTRY'

      1. Return 422 with the list of validation errors in case validation fails.

   3. Check csv_data input according to file structure

      1. Return 422 with the list of validation errors in case validation fails

   4. Check csv_data input file size - csv file with max 30000 lines is allowed.

      1. Return 422 The number of tasks for the job with a sequential execution strategy is limited to 30,000 in case validation fails

   File example:

*Note. Fields innms.sctid, innms.name, innms.name_original, innm_dosage_ingredients.is_primary, innm_dosage_ingredients.dosage.numerator_value, innm_dosage_ingredients.dosage.numerator_unit, innm_dosage_ingredients.dosage.denumerator_value, innm_dosage_ingredients.dosage.denumerator_unit, brand.code_atc can exist as an array. Values should be separated as | (respectively).

Service logic

1. Validate input according to schema

2. Create job with type create_medication_registry

3. For each line of input file create separate task of job

4. Each task must validate existing and create new entities of medications registry:

   1. Extract and search medications with type = INNM_DOSAGE, is_active = TRUE, innm_dosage.name, innm_dosage.form and innm_dosage.ingredients.dosage, innm_dosage.ingredients.is_primary:

      1. in case more than one medication with type = INNM_DOSAGE ,is_active = TRUE, innm_dosage.name, innm_dosage.form is found - return FAILED task status with error ('More than one INNM_DOSAGE with such name and form exist in medications table')

      2. in case more than one ingredient is found - return FAILED task status with error ('More than one INNM_DOSAGE ingredient with such fields exist in ingredients table')

      3. in case single medication with type = INNM_DOSAGE is found then check ingredients, in case ingredients of INNM_DOSAGE in DB are not equal to ingredients in uploaded register - return FAILED task status with error ('INNM_DOSAGE has different INNMS in ingredients table')

      4. in case medication with type = INNM_DOSAGE is not found - insert it according to Create full medication registry | medications (type = INNM_DOSAGE), its ingredients according to Create full medication registry | ingredients (for INNM_DOSAGE), brand according to Create full medication registry | medications (type = BRAND), its ingredient according to Create full medication registry | ingredients (for BRAND) and program medication with brand according to Create full medication registry | program_medications

         1. check existence of INNMs by innms.name_original

            1. in case innm is not found - insert it according to Create full medication registry | innms

            2. in case innm is found - skip innm creation.

            3. in case more than one innm is found - return FAILED task status with error ('More than one INNM with such name_original exist in innms table')

      5. in case medication with type = INNM_DOSAGE is found - proceed to brand.

   2. Extract and search connected medications with type = BRAND, is_active = TRUE, brand.name, brand.form, brand.package_qty, brand.package_min_qty, brand.certificate, brand.container, brand.manufacturer.name, brand.manufacturer.country, brand.certificate_expired_at and brand.ingredients.dosage, brand.ingredients.is_primary, brand.drlz_sku_id:

      1. in case more than one medication with such params is found - return FAILED task status with error ('More than one BRAND with such fields exist in medications table')

      2. in case single medication with type = BRAND is found then check ingredients, in case ingredient of BRAND in DB is not equal to ingredient of a brand in uploaded register - return FAILED task status with error ('Invalid BRAND ingredients in ingredients table')

      3. in case medication with type = BRAND is not found - insert brand according to Create full medication registry | medications (type = BRAND), its ingredient according to Create full medication registry | ingredients (for BRAND) and program medication with brand according to Create full medication registry | program_medications

      4. in case medication with type = BRAND is found - proceed to program medication.

   3. Extract and search connected program medication by:
      In case registry_number = NULL then search by medication_id (with type = BRAND) and program_medications.medical_program_id and program_medication.registry_number IS NULL;
      In case registry_number has id then search by medication_id (with type = BRAND) and program_medications.medical_program_id and program_medication.registry_number;

      1. in case more than one program medication with such params is found - return FAILED task status with error ('More than one PROGRAM_MEDICATION with such fields exist in program_medications table')

      2. in case program medication is not found - insert program medication with brand according to Create full medication registry | program_medication

      3. in case program medication is found - return FAILED task status with error ('Such medication already exist')

5. Return job identifier with result.
