Purpose

...

...

1. Only authenticated and authorized users with appropriate scope can invoke Prequalify Medication Request Request (MRR)

2. This method simply returns the result of data validation within each submitted medical program, but not creates any entities in the system

3. Each Medical program may have its unique conditions for the medication dispense. It can be based on analysis of personal info, medications list, terms, locations and combinations of them

4. Any Medical program can have separate block of branching logic configured at medical program settings by NHS administrator

5. Сompatibility is checked only for programs which are available in payload (array)

6. Successful invocation of the method returns decision for each program if it is valid or not to create Medication Request with submitted combination of parameters in the payload. If program status is invalid, the reason must be saved and returned in response.

Request data validation

Validate container_dosage field

$.container_dosage - volume of a medication’s primary container, which is requested by a doctor or issuer of a medication request, to be dispensed to patient.

1. Validate $.container_dosage field by schemata

   1. $.container_dosage.code and $.container_dosage.value should be both filled

      1. in case of error return 422 error ("required property %{property} was not present")

   2. $.container_dosage.system should be “MEDICATION_UNIT”

      1. in case of error return 422 error ("value is not allowed in enum")

   3. if $.container_dosage is filled then $.container_dosage.unit should be checked with the MEDICATION_UNIT dictionary by $.container_dosage.code as a key.

      1. in case of error return 422 error ("value is not allowed in enum")

2. Check if there is at list one record of Brand with requested primary container volume
   a. if not exist - return 404 error (message: "Not found any appropriate medication with such container parameters")

Validate priority

1. Check by schemata if $.priority is filled with the value of MEDICATION_REQUEST_PRIORITY dictionary

   1. in case of error return 422 error ("value is not allowed in enum")

Validate prior_prescription

1. Check that $.prior_prescription is UUID, exists and belongs to this person:

   1. is_active = true, and the same person. 

      1. in case of error - return 422 (message: "Prior prescription is not found")

Validate medication request type

...

1. Check compatibility of innm with medication list for the program

   1. if data is not found:

      1. add to response: status = INVALID

      2. add to response: rejection_reason = "Not found any medications allowed for create medication request for this medical program!Innm not on the list of approved innms for program {program_name}"

SELECT m0.id, m2.id, m2.package_qty, m2.package_min_qty, m3.id, m3.name
FROM medications AS m0
         INNER JOIN ingredients AS i1 ON i1.medication_child_id = {$.medication_id}
         INNER JOIN medications AS m2 ON i1.parent_id = m2.id
         INNER JOIN medical_programs AS m3 ON m3.id = {$.medical_program_id}
         INNER JOIN program_medications AS p4 ON (m3.id = p4.medical_program_id) AND (p4.medication_id = m2.id)
WHERE (i1.is_primary = TRUE)
  AND (m0.id = {$.medication_id})
  AND (m0.type = 'INNM_DOSAGE')
  AND (m0.is_active = TRUE)
  AND (m2.is_active = TRUE)
  AND (m3.medication_request_allowed = TRUE)
  AND (p4.is_active = TRUE)
  AND (p4.medication_request_allowed = TRUE)

2. Check if there is at list one record of Brand with requested primary container volume

a. if not exist - return 404 error (message: "Not found any appropriate medication with such container parametersInnm not on the list of approved innms for program {program_name}")

3. Check if there is at list one record medication_qty <= max_request_dosage or (max_request_dosage is null)

a. if not exist - return 404 error (message: "Not found any appropriate medication complying with max_request_dosage limit")

4. Check compliance of medication quantity: remainder of the division (medication_qty/package_min_qty) is equal to 0

...

Validate employee_id as described on Create Medication request Request. Except on Prequalify method a declaration has not checked for the employee.

6. Check Care plan and Activity

...

1. Validate "context" is an active (not entered-in-error) entity from corresponding dictionary, that belongs to the current patient

   1. Validate there is an entity in collection $.data.context.identifier.type.coding[0].code with id == $.data.context.identifier.value that belongs to the current patient

      1.  in case of error - return 200 with status = INVALID and rejection_reason = “Entity not found“

   2. encounter diagnosis is not empty in $.encounter.diagnosis

      1. in case of error return 422 ("Encounter without diagnosis can not be referenced")

   3. Validate context.identifier.type.coding[0].code = encounter

      1. in case of error return 422 ("value is not allowed in enum")

   4. encounter diagnosis is not empty in $.encounter.diagnosis

      1. in case of error return 422 ("Encounter without diagnosis can not be referenced")

9. Check person

It is needed to check if person has allowed verification status to get medication.

...

11. Check provision for a programs

It is needed to check if medical program can be provided by pharmacies.

1. If medical program has funding_source = LOCAL:

   1. Check there is exists any active medical program provision with msp_legal_entity_id equal to employee's legal entity

      1. in case of error - return 200 with status = INVALID and rejection_reason = "Medical program is not provided for legal entity specified in the medication request"
