Validate code is an existing service or service group that is allowed to be used in service_request
in case not found or is_active == false return 422 "Service(Service group) not found"
if request_allowed==false return 422 "Service request is not allowed for this service(service_group)"
in case based_on passed in request
If service_requests.code.identifier.value is service, validate $based_on[].activity.code.identifier.value = service_requests.code.identifier.value
in case error return 422, "Service in activity differs from service in service request"
If service_requests.code.identifier.value is service_group, validate $based_on[].activity.code.identifier.value = service_requests.code.identifier.value
in case error return 422, "Service group in care plan activity differ from service group in service request"
if service_requests.code.identifier.value is service/service group, validate $based_on[].activity.code.identifier.value is service/service group
in case error return 422, "Activity referes to '#{service/service group}' but service request refers to '#{service group/service}'"
Validate service category is equal to service request category in case service was defined as a code (not a service_group)
Select category from PRM.services where id = $.code.identifier.value
if PRM.services.category!=$.category OR PRM.services.category is not NULL return 422 "Service category does not match with service request category"
For each program validate it is an existing service program (type=service)
in case not found or is_active==false write result in Data collection according to apiary
in case type!= service write result in Data collection according to apiary - "Invalid program type"
check if medical_programs.medical_program_settings.care_plan_required == true then the request should contain a based_on with care plan and activity that contains the same medical program
in case of error return 422 with msg ("Care plan and activity with the same program should be present in request")
check that program equal to $.activity[].program
in case of error return 422 with msg ("Program from activity should be equal to program from request")
if program in SR is set check if $.activity[].program is not null
in case of error return error msg (“Program should not be present in request for this activity“)
For each program validate that service(or service_group) is an active member of the program
Select request_allowed, is_active from PRM.program_services where service_id(or group_id) == $.signed_content.code.identifier.value and program_id=$.program.identifier.value
if not found or is_active==false write result in Data collection according to apiary - "Service is not included in the program"
if request_allowed==false write result in Data collection according to apiary - "Service request is not allowed for this service(service_group) in this programm"
For each program validate that doctor is allowed to create service request with the program for the current patient
$.requester has an active declaration with the patient OR
$.requester works in the same MSP with doctor that has an active declaration with the patient AND doctors employee_type== DOCTOR
in case of error write result in Data collection according to apiary - "User is not allowed to create service request with the program for the patient"
Validate quantity
Check it is SimpleQuantity type, $.quantity.value is not empty, fractional and greater than zero
in case of error return 422 schema validation error
Check $.quantity.system is SERVICE_UNIT dictionary and $.quantity.code belongs to it
in case of error return 422 schema validation error
In case based_on passed in request and activity there has a quantity attribute:
Validate that system and code in activity's quantity isn’t null
in case of error return 422 (“A service request is not allowed to have a quantity attribute if the quantity in the related activity has no units”)
Validate that system and code in activity's quantity match to the system and code in the service request's quantity.
in case of error return 422 ("The quantity units must not differ from the quantity units in the activity")
Validate based_on
If submitted, check field has array with two values of Reference type: one is valid Care plan resource, another - Activity resource.
in case of error return 422 with msg ("expected a minimum of %{min} items but got %{actual}")
Verify Care plan:
It should belong to the same person as set in service request
in case of error return 422 with msg ("Care plan with such id is not found")
It should be in active status
in case of error return 422 with msg ("Care plan is not active")
Care plan's period end (if exist) should be greater than current date or equal.
Verify submitted Activity:
It belongs to the Care plan.
in case of error return 422 with msg ("Activity with such id is not found")
It has activity.detail.kind=service_request; activity.detail.product_reference=service_request.code[].value.
in case of error return 422 with msg ("Invalid activity kind")
It has scheduled, in_progress status
in case of error return 422 with msg ("Invalid activity status")
if quantity was set, then validate remaining_quantity greater then zero:
if quantity.code = PIECE:
select all active service requests based on current activity and calculate previously reserved quantity as sum of SR.quantity.value.
select all medical events based on not active service requests, that relates to current activity, and count their number as used quantity.
calculate reserved at the moment quantity as sum of previously reserved quantity and used quantity, including quantity from current SR
calculate remaining quantity by subtracting reserved at the moment quantity from activity's quantity
Check remaining quantity is greater then or equal to zero
in case of error return 422 "The number of available services according to the care plan activity has been exhausted"
if quantity.code = MINUTE:
select all active service requests based on current activity and calculate previously reserved quantity as sum of SR.quantity.value
select all procedures based on not active service requests, that based on current activity, and calculate used quantity as sum of procedure durations (calculates from performed_period attribute)
calculate reserved at the moment quantity as sum of previously reserved quantity and used quantity, including quantity from current SR
calculate remaining quantity by subtracting reserved at the moment quantity from activity's quantity
Check remaining quantity is greater then or equal to zero
in case of error return 422 "The number of available services according to the care plan activity has been exhausted"
if quantity.code is null:
select all medical events based on service requests, that are related to current activity, and count their number as used quantity.
calculate remaining quantity by subtracting used quantity from activity's quantity
Check remaining quantity is greater then zero
in case of error return 422 "The number of available services according to the care plan activity has been exhausted"
Verify activity period:
If it has scheduled_timing:
if bounds_period.end defined then check it greater than current date or equal.
If it has scheduled_period:
if scheduled_period.end defined then check it greater than current date or equal.
If patient is person - validate verification status:
If SR has based_on with valid activity, then skip this validation.
Else check patient's verification_status is not equal to NOT_VERIFIED.
in case NOT_VERIFIED - return error 409, "Patient is not verified"
Validate specimens, if submitted:
Check field has array with elements of Reference type on specimen resource
in case of error return 422 “not allowed in enum”
For each specimen check:
It exists in DB and belongs to the same patient as set in the service request:
in case of error return 422 "Specimen not found"
It has available status
in case of error return 422 "Invalid specimen status"
Service logic
For each program in array prepare response
If it is any or some errors from validations return “NOT VALID“ with error msg
