Specification

Apiary

Purpose

This WS is designed to create Request fo Medication request

There are two types of medication request:

  • plan - The request represents an intention to ensure something occurs without providing an authorization for others to act. Medication request with type plan can't be dispensed and only provide the instruction to administer the medicine. 

  • order - The request represents a request/demand and authorization for action. Medication request with type order can be dispensed

Authorize

  1. Verify the validity of access token

  2. Check user scope (scope = 'medication_request_request:write') in order to perform this action

    1. In case error - generate 401 response

Validate request (JSON schema)

Validate request using JSON schema. 

  1. in case of error return 422 error with msg ("required property %{property} was not present")

Validate employee

Purpose validation: Validation of an employee for the possibility of creating a medication request.

  1. Invoke employee_id from request

  2. Validate employee

    1. Validate that exists

      1. in case invalid return 422 error with msg ("Employee not found")

    3. Validate that $.employees.legal_entity_id == client_id from token

      1. in case invalid return 422 error with msg ("Employee does not belong to legal entity from token")

    4. Validate that $.employees.employee_type == <employee_type>

      1. in case medical_program_id present in request validate medical_program_settings.skip_employee_validation == false (or absent)

        1. validate <employee_type>

          1. get $.medical_programs.medical_program_setting by medical_program_id from request

                1. get $.declarations by employee_id, person_id, status=ACTIVE or check MEDICATION_REQUEST_DECLARATION_VERIFY param (which allow to create medication request for any doctor from LE where person have declaration)

                  1. if not found - return 422 error  (message: "Employee must have an active declaration with the patient to create medication request!")

              3. in case employee_type = SPECIALIST

                1. get $.employees.speciality.speciality(speciality_officio == true)

Validate multiplicity & medication request allowed for participants

Purpose validation:  Request quantity must have multiplicity package_min_qty for linked medications.  Result (Mod or % operator) must = 0 . 
Also if present Medical_program - must exists medications with `medication_request_allowed`== TRUE for participants.

  1. If `$.medical_program_id` present in payload (non null) - Check exist (IF EXIST()) medication & participant 

    1. if not exist - return 404 error (message: "Not found any medications allowed for create medication request for this medical program!")

      SELECT *
FROM medications MI											-- 2nd level: Medication - type = INNM_DOSAGE
	INNER JOIN ingredients I
		ON I.medication_child_id = MI.id
			AND I.is_primary =TRUE
    INNER JOIN medications MED                              -- 3rd level: Medication - type = BRAND

			AND MED.is_active == TRUE
WHERE MI.id == $.medication_id
	AND MI.type == INNM_DOSAGE
	AND MI.is_active == TRUE

    3. Vaildate multiplicity (Mod == 0) for all elements in result (`$.medication_qty` Mod `MED.package_min_qty` == 0)

      1. if all result of Mod operator  - NOT 0 - return 409 eror (message: "The amount of medications in medication request must be divisible to package minimum quantity") 

Generate number & verification_code for Medication request

  • Generate human readable number for receipt (See specs)

    Structure number XXXX-1234-5678-9012-345-C , where:
- XXXX - series: numbers + only some letters (A, E, H, K, M, P, T, X)
- 1234-5678-9012-345 - randomly generated numbers
- C - checksum: Should be calculated using the Damn algorithm or Verhoeff algorithm
After new Request number was generated we should check that it is unique in the DB (entity: medication_request + medication_request_request

    • Generate verification_code for MPI.person_authentication_methods == OTP or OFFLINE

      Structure code 1234, where:
- 1234 - randomly generated numbers 

Create Medication request Request

  1. set:

    1. dispense_valid_from = created_at

    2. dispensed_valid_to = dispensed_valid_from + dispense_period

  2. Fill 'data' structure for Response & save in IL.medication_request_requests

Generate content for response

  • Generate data structure with Responce WS structure

    • Set IL.medication_request_requests this structure

  • in case if response is VALID enrich response with urgent_data:

    • get authetification_method by person_id and return masked number (in case if any)

"urgent": {
    "authentication_method_current": {
      "type": "OTP",
      "number": "+38093*****85"
    }
  }
