Service logic

1. Save signed content to media storage

2. Update Medication dispense data in OPS DB:

   1. set status  =  ‘PROCESSED’

   2. updated_by = user_id

   3. updated_at = now()

3. Update related Medication request data in OPS DB:

   1. set status  =  ‘COMPLETED’

   2. updated_by = user_id

   3. updated_at = now()

4. Write changes to event manager (Medication dispense and Medication request)

5. 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):

   1. Set activity status to in_progress if previous activity status was scheduled 

   2. Check the MD identifier in outcome_reference attribute of the activity:

      1. if not found:

         1. Add reference on the medication dispense resource to the outcome_reference attribute .

         2. If quantity in the activity was set then calculate and set remaining quantity:

            1. select all MD in status PROCESSED related to MR which based on care plan and current activity

            2. calculate dispensed quantity in the current activity as sum of medication_qty in the filtered MD list

            3. calculate remaining quantity by subtracting dispensed quantity from activity quantity

            4. update remaining_quantity value in the activity with calculated value

      2. If found, then skip updating activity (it means that activity has been already updated by event from current MD processing).
