Purpose
This WS is designed to Pre-qualify data of Device Request (post) - check whether it's possible to create Device request with specified parameters and within the particular Medical program.
...
Only authenticated and authorized users with appropriate scope can invoke Prequalify Device Request
This method simply returns the result of data validation within each submitted medical program, but not creates any entities in the system.
Each Medical program may have its unique conditions for the Device Request. It can be based on analysis of personal info, device definition list, terms, locations and combinations of them.
Any Medical program can have separate block of branching logic configured at medical program settings by NHS administrator.
Сompatibility is checked only for programs which are available in payload (array).
Successful invocation of the method returns decision for each program if it is valid or not to create Device request with submitted combination of parameters in the payload. If program is invalid, the reason must be returned in the response.
It is not allowed for prepersons, because dispense with program is forbidden for them
...
Extract user_id from token. Check that requester belongs to one of the user’s employee.
in case of error - return 422 ('User is not allowed to create device request for the requester')
Check requester is an active and approved employee.
in case of error - return 422 ('Invalid employee status')
Check requester relates to the legal entity (client_id from token).
in case of error - return 422 ('Employee <id> doesn't belong to your legal entity')

in case not found - return reject_reason = “No appropriate participants found for this medical program“
Make validation according to medical program settings:
If skip_employee_validation = false (null/absent), then $.requester should be validated:
If employee_types_to_create_request parameteris set, then check if it contains employee type of the requester
in case is not found - return reject_reason = “Employee type of the requester doesn't allow to create Device Request with the medical program”
In case employee type of the requester is SPECIALIST, then additional validations may be performed:
If speciality_types_allowed is set, then check if it contains speciality of the requester (speciality_officio=true):
in case is not found - return reject_reason = "Employee's specialty of the requester doesn't allow to create Device Request with the medical program"
In case employee type of the requester is DOCTOR, then additional validations may be performed:
if skip_request_employee_declaration_verify = false (null/absent), then get declaration by employee_id of the requester, person_id and status=ACTIVE
in case is not found - return reject_reason = "Only doctors with an active declaration with the patient can create Device Request with the medical program"

If skip_treatment_period = false (null/absent), then:
Get all active/completed Device Requests with $.code or $.code_reference (depending on attribute provided in request), $.medical_program_id, $person_id
If such was found, get the Device Request with the latest occurrence_period.end date and check:
its occurrence_period.end less then $.occurrence_period.start from the request
in case of error - return reject_reason = ”It can be only one active / completed Device Request for the same code and patient at the same period of time”
if its occurrence_period.end greater than or equal to current date, then in addition check:
If occurrence_period of found Device Request is greater than or equal to DEVICE_REQUEST_STANDARD_DURATION, then $.authored_on from the request should be greater then (occurrence_period.ended at - DEVICE_REQUEST_MAX_RENEW_DAYS) of the found Device Request
else $.authored_on from the request should be greater then (occurrence_period.ended at - DEVICE_REQUEST_MIN_RENEW_DAYS)
in case of error - return reject_reason = “It's to early to create new Device Request for such code and medical program”
If request_max_period_day is set, then check if it is not exceeded by the number of days in the $.occurrence_period of the request
if exceeded - return reject_reason = “Occurrence period length exceeds allowed value for the medical program“
if there is parameter device_request_allowed_code_types, then check values in the array:
if it includes
CLASSIFICATION_TYPE- it is allowed to pass $.code in the requestif it includes
DEVICE_DEFINITION- it is allowed to pass $.code_reference in the requestin case of a mismatch between the filled field and the config values - return 422 ("<Device definition/Device classification type> is not allowed to set for this medical program").
If care_plan_required = true, then:
Reference to activity in $.based_on is required
in case of error - return reject_reason = “Activity with the same program should be present in request”
...
11. Validate priority
Validate value in the field $.priority, string, optional.
Check that value is in allowed active values from
device_request_prioritydictionary.in case of error - return 422 ('value is not allowed in enum')
...
12. Validate supporting info
Validate values in the field $.supporting_info, array, optional. Validate each value with the following rules:
Validate that referenced resource is one of the following (diagnostic_report, observation, condition, procedure, encounter, episode, device, device_association)
in case of error - return 422 ("Referenced resource in supporting_info is not allowed")
Validate that entity is not in status "entered_in_error"
in case of error - return 422 ("Entity in status "entered_in_error" can not be referenced")
Check that resource belongs to the patient ($.subject)
in case of error - return 422 ('Referenced resource not found')
...
13. Validate performer

in case of error - return 422 ("Legal entity referenced as performer is in invalid status")
...
14. Validate parameter
Validate values in the field $.parameter, array, optional. Validate each value with the following rules:
Check that value from $.parameter.code is in allowed active values from
device_propertiesdictionary.in case of error - return 422 ('value is not allowed in enum')
Check $.parameter.value[x] is one of the following:
value_codeable_concept,value_quantity,value_boolean,value_range,value_stringin case of value[x] is missing - return 422 ('At least one of the parameters must be present')
in case of more than one value[x] provided - return 422 ('Only one of the parameters must be present')
in case of value[x] is provided with incorrect type - return 422 ('type mismatch. Expected [x] but got <type>')
Service logic
Generate structure for response
If general error found at Validate device request section, that doesn’t depend on medical program, then return corresponding error code with error message
If general validation passed, then collect array for all programs in payload with status for each (VALID or INVALID) and rejection_reason
Generate response according to specification
