Properties of a REST API method document

Purpose

This method is designed to create Medication dispense. The medication dispense is the result of a pharmacy system responding to a medication order.

Key points

1. Only authenticated and authorized users of legal entity can create Medication dispense.

2. Can be used both for creating and processing Medication dispense (depending on the requirements of the program).

   1. In order to process dispense payment_id (optional) and payment_amount should be added.

3. Invoke Qualify Medication request by ID for receiving information about program participants.

4. Dispense of medication is possible only under Medication request and during the period specified in Medication request.

5. Several medications from different manufacturers with the same substance can be dispensed at a time.

   1. The total of medication_qty should be less or equal to the medication quantity specified in the Medication request.

Logic

1. Get skip_medication_dispense_sign from medical program settings.

2. If skip_medication_dispense_sign = false or absent:

          2.1. Check payment_id, payment_amount is absent in the request.

in case if present - return 422 with path: $.<field_name>  and message "schema does not allow additional properties"

          2.2. Add record to medication_dispenses table:

          2.3. Add records to medication_dispense_details table:

          2.4. Add records to medication_2d_codes table (for each 2d code object in array):

1. If skip_medication_dispense_sign =

true:

             3.1. Check if payment_amount in the request.

• in case is absent - return 422 with path: $.payment_amount and message "required property payment_amount was not present"

             3.1. Call Process Medication Dispense by Pharmacy User process, but without validation of the previously created (NEW) medication dispense, digital sign and storage signed content to the bucket.

             3.2. Add records as described on steps 2.2-2.4, but with following differences: 

             medication_dispenses table

Preconditions

1. Medication Request should be Сreated by MSP

2. Medication Request should be found and qualified by pharmacist

         • in case of error - return 422 ('For Medical program with funding_source = "%{funding_source}" medication dispense dispensed_at must be equal to or less than current date')

Validate Medication quantity

1. Get multi_medication_dispense_allowed parameter from medical program settings:

   1. if it is true - check that requested medication quantity less or equal to available medication quantity in Medication Request (the way how to calculate available medication quantity is following:
      available_qty = medication_request.medication_qty - used_qty,
      where used_qty is the sum of medication_qty from medication_dispenses with medication_request_id = $.medication_request_id)

      1. medication_qty <= available_qty

         1. in case of error - return 422 ('Dispensed medication quantity must be lower or equal to medication quantity in Medication Request. Available quantity is #{available_qty}')

   2. if it is false (absent) - check that requested medication quantity equal to medication quantity in Medication Request

      1. medication_qty = medication_request.medication_qty

         1. in case of error - return 422 ('Dispensed medication quantity must be equal to medication quantity in Medication Request')

Validate Program medication

In case medications are dispensed to patient under specific medical program, program medication id must be provided provided by client or calculated by the system

In case program medication id exists in request:

1. Check that this program medication id relates to provided medical program and relates to provided medication

   1. in case of error - return 422 ('Invalid program medication id')

Calculate program medication id if it is absent in request:

1. Get last program_medication_id related to medical program and medication

   1. in case of error - return 422 ('There are no active program medications for this program and medication')

Validate Medication multiplicity

This validation must be done only in case when medication dispensed to patient as brand. In case of extemporaneous medications this validation must be skipped

1. Check that requested medication quantity in dispense for all medications is multiplier of package_min_qty for this medications.id

   1.  Mod($medication_qty, medications.package_min_qty) = 0

      1. in case of error (if at least one of medication don't pass verification) - return 422 error ('Requested medication brand quantity is not a multiplier of package minimal quantity')

Validate Medication discount amount

1. Define reimbursement_type (get from program_medications by program_medication_id).

2. Validate percentage discount price.
   Check if reimbursement_type == percentage and percentage_reimbursement_amount = 0
   (the way how to calculate percentage_reimbursement_amount is following:
   percentage_reimbursement_amount = sell_price (from request) * percentage_discount (from program_medications) /100)

   • In case if discount_amount != 0 - return 422 ('Requested discount price must be equal to 0')

   • Else (if discount_amount = 0)  - finish validation (do not validate 3, 4)

3. Validate allowed reimbursement amount.
   Check that requested discount price is less or equal to allowed reimbursement amount for the requested medication quantity
   (the way how to calculate allowed reimbursement amount is below.
   for type == percentage use percentage_reimbursement_amount, for fixed = use reimbursement_amount from program_medications):
     There are two different formulas depending on medication type to be dispensed

   1. If medication.type = ‘BRAND’:

      1. discount_amount <= reimbursement_amount * (medication_qty/package_qty)

   2. If medication.type = ‘INNM_DOSAGE’:

      1. discount_amount <= reimbursement_amount * medication_qty

4. Validate the ratio of discount price to reimbursement amount.
   Check that the ratio of requested discount price to allowed reimbursement amount is more or equal to allowed rule (including deviation) for the requested medication quantity
   (the way how to calculate allowed reimbursement amount is below.
   for type = percentage use percentage_reimbursement_amount, for fixed - use reimbursement_amount from program_medications):
         There are two different formulas depending on medication type to be dispensed

   1. If medication.type = ‘BRAND’:

      1. discount_amount/ (reimbursement_amount * (medication_qty/package_qty)) >= 1 - deviation

   2. If medication.type = ‘INNM_DOSAGE’:

      1. discount_amount/ (reimbursement_amount * medication_qty) >= 1 - deviation

5. In case of error - return 422 ('The ratio of requested discount price to allowed reimbursement amount must be greater or equal to <1 - deviation>')

Validate 2d codes

• Check that medication_2d_codes array contains at least one element (array is not empty)

  • in case of error - return 422 ('Expected a minimum of %{min} items but got %{actual}')

• For all objects in array check that string 'medication_2d_code' is not null or empty

  • in case of error - return 422 ('Not allowed to save empty 2d code')
