Description:

Decision support recommendation for cervical cancer screening eligibility (CXCA.D2). Evaluates the rules from Mongolia MOH Order A/641 (2020) section 2.2 via the CXCAD2DTScreeningEligibilityLogic CQL library; when the client is due, recommends instantiating the CXCAD2HPVScreeningServiceRequest ActivityDefinition.
Libraries:

Actions:
Recommend HPV high-risk DNA screening (client is due): Client is at the binding target age (35 or 45 per A/641 section 2.2), has not had a hysterectomy, and has not been screened in the current cycle. Create a proposed ServiceRequest for HPV high-risk DNA testing.
If: Applicability: (Client is due for HPV screening (legal binding))
Then: Definition: CXCAD2 — HPV Screening Service Request
Defer screening — client already screened in current cycle: Client is at a binding target age but has had a recent valid HPV screening result. Per A/641 section 2.2 they are not due for re-screening at this encounter. Inform the client of their next due date.
If: Applicability: (Client not due — already screened in current cycle (legal binding))
Defer screening — client outside binding target age range: Client is not at a binding target age (35 or 45 per A/641 section 2.2 for HPV-test-capable facilities). Note: cytology-only facilities follow a different age cycle (30, 33, 36, ..., 60 every 3 years per A/641 section 2.2 cytology pathway) — see the separate cytology-pathway PlanDefinition (deferred to a future Phase 5 chunk).
If: Applicability: (Client excluded — outside target age range (legal binding))
Exclude from screening — prior hysterectomy: Client has had a hysterectomy. Per A/641 section 2.2, women who have had a hysterectomy for non-cervical-cancer indication and who have a documented negative post-operative vaginal-smear cytology are exempt from cervical cancer screening. Verify the indication and the post-operative cytology status before fully excluding.
If: Applicability: (Client excluded — prior hysterectomy (legal binding))
