Purpose
This method is designed to process previously created Medication dispense
Key points
Only authenticated and authorized users of a legal entity who has created Medication dispense can process Medication dispense
Medication dispense can be processed only from ‘NEW' status.
The process should be signed with DS. So, all the Medication dispense data should be submitted.
Invoke Get Medication dispense details by Pharmacy User to obtain previously created Medication dispense. In order to process dispense payment_id (optional) and payment_amount (optional, if medical program has funding sourse != NHS) should be added.
Specification
Logic
Save signed content to media storage
Update Medication dispense data in OPS DB:
set status = ‘PROCESSED’
updated_by = user_id
updated_at = now()
Update related Medication request data in OPS DB:
set status = ‘COMPLETED’
updated_by = user_id
updated_at = now()
Write changes to event manager (Medication dispense and Medication request)
Change Care plan activity (If related medication request has reference on Care plan, then corresponding care plan activity should be changed in async way after Medication dispense processed. Update activity events invokes using ops.medication_dispense_process table):
Set activity status to in_progress if previous activity status was scheduled
Check the MD identifier in outcome_reference attribute of the activity:
if not found:
Add reference on the medication dispense resource to the outcome_reference attribute .
If quantity in the activity was set then calculate and set remaining quantity:
select all MD in status PROCESSED related to MR which based on care plan and current activity
calculate dispensed quantity in the current activity as sum of medication_qty in the filtered MD list
calculate remaining quantity by subtracting dispensed quantity from activity quantity
update remaining_quantity value in the activity with calculated value
If found, then skip updating activity (it means that activity has been already updated by event from current MD processing).
Preconditions
If skip_medication_dispense_sign=false, MD should be created

Return 404 ('not_found') in case of error
Check Medication dispense belongs to legal entity
Return 404 ('not_found') in case of error
Validate User
Extract user_id from token
Return 404 ('not_found') in case employee didn’t create medication dispense
Validate Care plan and Activity
It is needed to check if medication request with a program allowed to be created for specified care plan and activity.
If based_on submitted, check field has array with two values of Reference type: one is valid Care plan resource, another - Activity resource.
Verify Care plan:
It should belong to the same person as set in MRR
in case of error return 422 with msg ("Care plan not found")
It should be in active status
Verify submitted Activity:
It belongs to the Care plan.
in case of error return 422 with msg ("Activity not found")
It has activity.detail.kind=medication_request; activity.detail.product_reference=medication_id.
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 it hasquantitythen calculateremaining quantity:select all MRR in status NEW which based on current activityselect all MR in statuses ACTIVE, COMPLETED based on current activitycalculate reserved at the moment medication quantity as sum of medication_qty in the filtered MRR and MR list, including medication_qty from current MRRcalculate remaining quantity by subtracting reserved quantity from activity quantityCheckremaining quantityis greater then or equal to zeroin case of error return 409 "The total amount of the prescribed medication quantity exceeds quantity in care plan activity"
check that medical_program_id equal to $.activity[].program
in case of error return 422 with msg ("Medical program from activity should be equal to medical program from request")
Validate started_at/ended_at of Medication request Request:
if care plan activity has detail.scheduled_timing.repeat.bounds_period - validate started_at/ended_at within bounds_period
if care plan activity has detail.scheduled_period - validate started_at/ended_at within scheduled_period
else - validate started_at/ended_at within care_plan.period
in the case of started_at/ended_at is not within care_plan.period return 422 with msg ("Invalid care plan period")
Validate signed content
Check that signed content is equal to online generated dispense with ids in DB
Do not compare:
payment_amount field
payment_id field
medication_request/legal_entity object
medication_request/division object
medication_request/employee object
medication_request/person/id field
medication_request/rejected_at field
medication_request/rejected_by field
in case error return 422 ("Signed content does not match to previously created dispense")
Validate transition
Get status of Medication dispense by $.id in OPS DB. Check that Medication dispense is in status ‘NEW’
in case of error - return 409 ("Can't update medication dispense status from {status} to PROCESSED")
For more information look at Medication dispense status model
Validate payment_amount
In case if medical program has funding sourse == NHS check that payment_amount is submitted and greater or equal to 0
in case of error - return 422 ("expected the value to be >= 0")
Validate related Medication request
Medication request should be active in order to process medication dispense
is_active = true
status = 'ACTIVE'
In case error - return 409 ("Medication request is not active")
Medication request should not be blocked in order to process medication dispense
is_blocked <> true
In case error - return 409 ("Medication request is blocked")
Medication request should be active in order to process medication dispense
is_active = true
status = 'ACTIVE'
In case of error - return 409 ("Medication request is not active")
Medication request should be up to date
medication_request.dispense_valid_from ≤ now OR medication_request.dispense_valid_to ≥ now
In case of error - return 409 ("Invalid dispense period")
Checking the status of the legal entity where the medication request was issued
status in ('ACTIVE', 'CLOSED', 'REORGANIZED')
In case of error - return 422 ("value is not allowed in enum")
Check if related medication request has reference on the Care plan - based_on attribute filled. If it has, validate following:
Care plan is not in final status.
In case of error - return 409 error (Care plan is not active)
If end_date Care plan is present then it should be less than or equal than todays date
In case of error - return 409 ("Care plan expired")
Corresponding Care plan activity is not in final status.
In case of error - return 409 error (Care plan activity should be scheduled or in_progress)
Response structure
Example:
Processing
Save signed content to media storage
Update Medication dispense data in OPS DB:
set status = ‘PROCESSED’
updated_by = user_id
updated_at = now()
Update related Medication request data in OPS DB:
set status = ‘COMPLETED’
updated_by = user_id
updated_at = now()
Write changes to event manager (Medication dispense and Medication request)
Change Care plan activity (If related medication request has reference on Care plan, then corresponding care plan activity should be changed after Medication dispense processed):
Set activity status to in_progress if previous activity status was scheduled
Check the MD identifier in outcome_reference attribute of the activity:
if not found:
Add reference on the medication dispense resource to the outcome_reference attribute .
If quantity in the activity was set - validate $.activity.details.remaining_quantity_type:
if $.activity.details.remaining_quantity_type = for_request than:
select all MRR in status NEW which based on current activity
select all MR in statuses ACTIVE based on current activity
select all MD (medication dispenses) in status PROCESSED related to the Medication requests which are in status COMPLETE, REJECTED, EXPIRED
calculate:
reserved_qty as sum of medication_qty in the filtered MRR and MR list
dispensed_qty as sum of medication_qty in the filtered MD list
calculate and update remaining quantity by subtracting reserved_quantity and dispensed_qty from activity quantity
if $.activity.details.remaining_quantity_type = for_use than:
select all MD in status PROCESSED related to MR which based on care plan and current activity
calculate dispensed quantity in the current activity as sum of medication_qty in the filtered MD list
calculate remaining quantity by subtracting dispensed quantity from activity quantity
update remaining_quantity value in the activity with calculated value
If found, then skip updating activity (it means that activity has been already updated by event from current MD processing).
