Purpose

1. This WS is designed to create approval on entity, which aggregate other entities (episode_of_care, diagnostic_report, care_plan), OR forbidden group OR diagnoses group, OR on service_request including it’s permitted_resources OR on cancel for encounter and procedure OR patient.

2. Approvals are processed in the async way

3. Only authenticated and authorized employees with appropriate scope can create approval.

4. Approvals with “write” access give “read” access by default. Employee with verified not expired approval with “write” access will be able to read data of specified in approval medical_event (if is possible according to ABAC-rules)

Validate access_level

1. Validate that access_level correspond to granted_resources:

   1. In case error return 422 ("Resource types [\"$.granted_resources[].code\"] not allowed to use write access_level")

Validate authorize_with

The patient can pass the id of his auth_method which he wants to confirm the approval. The necessary auth method can be found by making Get person's auth methods

1. validate auth_method.id is UUID

   1. in case error return 422

2. search auth method in MPI.person_authentication_method

   1. in case error return 422, "such authentication method doesn't exist"

3. search auth method of this patient where  MPI.person_authentication_method.person_id = $.patient.id

   1. in case error return 422, "such authentication method does not belong to this person"

4. validate if auth_method.type = NA

   1. error return 422, "Сannot be confirmed by a method with type= NA. Use a different method."

5. validate that this method is active ( authentication_method.ended_at > now() and is_active = true)

This field is optional and set in new field authorize_with and save type and phone_number in approvals.urgent.authentication_method_current.

If approval doesn't have this field, then choose that method which is returned from mpi as person's default method.

Processing

Service logic

1. Set is_verified = false

2. All the approvals where is_verified = false should be deleted 12 hours after creation - env. configuration parameter

3. All approvals depends on value of granted_resources has its own expires_at config parameter - env. configuration parameter

4. Approvals with child_resources will be created ON entity which is context of this child_resources

5. For approvals on child_resource with resource and on service_request:

   1. set child resource to block reason

   2. set service_request to block reason

6. Check type of authentication_method for patient:

   1. If type = 'OTP' send SMS type of granted_to & type of entity in granted_resources:
