Overview

Procedure can be registered in eHealth as a part of encounter pckg or just by itself with reference on Service Request. This WS is designed to create a new procedure separately from encounter pckg. 

Procedure should be registered in the system after it was performed for a patient.

Requirements

1. Реєстрація запису про проведену процедуру в ЦК

Specification

1. Apiary

Validations

Authorization

• Verify the validity of access token
  • Return (401, 'unauthorized') in case of validation fails
• Verify that token is not expired
  • in case of error - return (401, 'unauthorized')
• Check user scopes in order to perform this action (scope = 'procedure:write')
  1. Return (403, 'invalid scopes') in case of invalid scope(s)

Validate digital signature

Decode content that is encrypted in an electronic digital signature.
Use Digital signature WS. Method checks digital signature and returns result.
See service specification

1. Ensure that digital signature is valid

2. Validate that recorded_by of procedure is a current user

2.1. Get token metadata

• Extract user_id, client_id, client_type

2.2. Determine the party_id associated with this user_id

SELECT pu.party_id
FROM party_users pu
WHERE pu.user_id = :user_id;

SELECT e.id
FROM employees e
WHERE e.party_id = :party_id
AND e.legal_entity_id = :client_id;

3. Validate that DS belongs to recorded_by

3.1. Determine the party_id associated with recorded_by ($.recorded_by.identifier.value)

SELECT p.tax_id
FROM employees e, parties p
WHERE e.party_id = p.id
AND e.id = :recorded_by;

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