Purpose
This WS is designed to create Request for 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
Specification
Key points
Only authenticated and authorized users with appropriate scope can Create Medication Request Request (MRR)
Patient should be stored in hashed form according to security requirements.
Authorize
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_request_request:write')
return 403 (“Your scope does not allow to access this resource. Missing allowances: medication_request_request: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):
in case not match - return 403 ("Access denied. Party is not verified")
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")
Validations
Validate container_dosage field
$.container_dosage
- volume of a medication’s primary container, which is requested by a doctor or issuer of a medication request, to be dispensed to patient.
Validate $.container_dosage field by schemata
$.container_dosage.code and $.container_dosage.value should be both filled
in case of error return 422 error ("required property %{property} was not present")
$.container_dosage.system should be “MEDICATION_UNIT”
in case of error return 422 error ("value is not allowed in enum")
Check if there is at list one record of Brand with requested primary container volume
a. if not exist - return 404 error (message: "Not found any appropriate medication with such container parameters")
Validate priority
Check by schemata if $.priority is filled with the value of MEDICATION_REQUEST_PRIORITY dictionary
in case of error return 422 error ("value is not allowed in enum")
Validate prior_prescription
Check that $.prior_prescription is UUID, exists and belongs to this person:
is_active = true, and the same person.

in case invalid return 422 error with msg ("Employee does not belong to legal entity from token")
If medical program is present and has medical_program_settings with skip_employee_validation == false (or absent), then validate <employee_type>:
validate if employee_type is present in medical_program_settings employee_types_to_create_request variable
in case invalid return 422 error with msg ("Employee type can't create medication request with medical program from request")
in case employee_type = DOCTOR
if variable skip_request_employee_declaration_verify = false or null/absent

if not found - return 422 error "Only doctors with an active declaration with the patient can create medication request with medical program from request!"
else skip declaration verification on employee level (if true)
if variable skip_request_legal_entity_declaration_verify = false or null/absent
then: get $.declarations by employee's legal_entity_id, person_id, status=ACTIVE
if not found - return 422 error "Only legal entity with an active declaration with the patient can create medication request with medical program from request!"
else skip declaration verification on legal entity level (if true)
else if both are true - skip declaration verification at all
in case employee_type = SPECIALIST
get $.employees.speciality.speciality(speciality_officio == true)

inserted_at - date when Medication request was registered in E-Health
started_at/ended_at - Treatment period. Cannot be less than MR expiration period. Defined by doctor.
dispense_valid_from - Used for dispense validation. As for now equals Created at.
dispense_valid_to - Implements dispense expiration period. If MR has medical program setting with not empty parameter dispense_period_day, then dispense_valid_from + dispense_period_day, else Dispense valid from + medication_dispense_period global parameter value.
Purpose validation: Must be: ended_at >= started_at >= created_at

skip validating frequency of receiving drugs
Validate period length (ended_at - started_at):
If medical program has been submitted:
validate request according to logic: PreQualify Medication request: 7. Validate period
else:
Check that medication request period less than or equal to request_max_period_day parameter from charts
in case of error - return 409 “Period length exceeds default maximum value“

Service Logic
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
set:
dispense_valid_from = created_at
dispensed_valid_to = dispensed_valid_from + dispense_period
Fill 'data' structure for Response & save in IL.medication_request_requests
If encounter is present in the request context then based on it - fill the IL.medication_request_requests.context_episode_id
Fill separately
data_employee_id,
data_intent,
data_based_on_care_plan_id,
data_based_on_activity_id,
data_context_id,
data_patient_id,
data_legal_entity_id,
data_authorize_with
If the medication request request is based on activity with quantity - set remaining_quantity for the activity which was calculated at validation Create Medication Request: Validate based_on (6. Check Care plan and Activity, p. 2.d.1 )
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:
if authorize_with is submitted - get authentication_method details and return masked number (in case if any)
else if authorize_with is not submitted - get default authentication_method by person_id and return masked number (in case if any)
