PlanDefinition: CXCA.D18.S — Recall Scheduling

Official URL: http://smart.who.int/cxca/PlanDefinition/CXCAD18SRecallScheduling Version: 0.0.1
Draft as of 2026-05-14 Computable Name: CXCAD18SRecallScheduling

Decision support for recall and re-call per Mongolia MOH Order A/641 (2020) section 2.3. Evaluates seven timeout triggers (HPV sample timeout, positive-result follow-up timeout, biopsy timeout, treatment-after-biopsy timeout, cytology unread timeout, second-reminder, missed scheduled exam) and instantiates a CommunicationRequest reminder for each fired trigger. The 187 LTFU women from the April 2026 Khan-Uul pilot represent the empirical case for why this layer matters — DE39 (positive-result follow-up timeout, 4 weeks) is the trigger that should fire for each of them.

Libraries:

Actions:
Recall — HPV sample result missing more than 3 weeks: An HPV sample was dispatched more than 3 weeks ago and no result has been entered. Issue a reminder to follow up with the lab.
If: Applicability: (Recall — HPV sample result timeout)
Then: Definition: CXCAD18 — Recall Reminder CommunicationRequest
Recall — positive screening result without follow-up exam after 4 weeks: A positive screening result was entered more than 4 weeks ago and no follow-up examination has been recorded. Issue a reminder to the patient and the clinician. THIS IS THE LTFU-PREVENTION TRIGGER — the 187 women lost to follow-up in the April 2026 Khan-Uul pilot would each have had this trigger fire.
If: Applicability: (Recall — positive result follow-up timeout)
Then: Definition: CXCAD18 — Recall Reminder CommunicationRequest
Recall — biopsy result missing more than 4 weeks: A biopsy sample was received at the lab more than 4 weeks ago and no histopathology result has been entered. Follow up with the lab.
If: Applicability: (Recall — biopsy result timeout)
Then: Definition: CXCAD18 — Recall Reminder CommunicationRequest
Recall — no treatment record more than 4 weeks after positive biopsy: A positive biopsy result has been entered for more than 4 weeks and no treatment record exists. Issue a reminder to schedule treatment.
If: Applicability: (Recall — treatment after positive biopsy timeout)
Then: Definition: CXCAD18 — Recall Reminder CommunicationRequest
Recall — cytology slide unread more than 2 weeks at lab: A cytology slide was received more than 2 weeks ago and no cytologist conclusion has been entered. Follow up with the lab.
If: Applicability: (Recall — cytology slide unread timeout)
Then: Definition: CXCAD18 — Recall Reminder CommunicationRequest
Recall — second reminder needed (first sent more than 4 weeks ago): A first reminder was sent more than 4 weeks ago and the underlying gap remains unresolved. Issue a second reminder.
If: Applicability: (Recall — second reminder needed)
Then: Definition: CXCAD18 — Recall Reminder CommunicationRequest
Recall — missed scheduled examination: Patient missed a scheduled examination. Immediate reminder — no timeout wait.
If: Applicability: (Recall — missed scheduled examination)
Then: Definition: CXCAD18 — Recall Reminder CommunicationRequest
