Store-and-Forward Diagnostic Edge Assurance Director

The mandate

Clinics use compact edge systems to acquire images, run bounded diagnostic support and forward cases when connectivity permits. A recent quality review found packages whose consent state, model version, image transformation, local interpretation and later specialist amendment could not be reconstructed as one history. The defined problem is to specify reliable offline evidence and reconciliation without making remote care depend on continuous cloud access.

The named deliverable is a Store-and-Forward Diagnostic Edge Assurance Design and Clinic Conformance Kit. It must define case identity, provenance, signed model and policy state, offline decision limits, queue integrity, prioritised synchronisation, conflict resolution, amendment rules, data minimisation, operator evidence, monitoring and executable conformance scenarios for three representative clinic configurations.

Three milestones span three months: by day fifteen, agree the clinical journey, risk classes and evidence inventory; by week eight, deliver the assurance design and run failure scenarios in two clinic environments; and by week thirteen, submit the conformance kit, validated reference flow, rollout gates and unresolved clinical-policy register. Each milestone invoice follows panel acceptance.

The diagnostic safety panel and quality lead will accept the work only when every result traces to the correct patient, consent, acquisition, transformation, model, reference data and human amendment; conflicting offline and central histories resolve by explicit clinical rules; delayed or duplicate packages fail safely; four clinic staff can execute the conformance scenarios; and bandwidth assumptions are measured in low-connectivity operation.

The client will provide de-identified case packages, clinic devices, model and policy versions, consent flows, connectivity traces, field incidents, central interfaces, clinical reviewers and approved test locations. The consultant will not validate diagnostic efficacy, provide patient care, change clinical policy, procure devices, operate production queues or redesign unrelated health records; conclusions will identify where clinical evidence remains required.

Why this is external work

Clinical, platform and field teams each own part of the case journey, but none has authority to independently test the complete offline evidence chain they collectively designed. Existing audits begin after data reaches the centre and therefore miss loss or ambiguity created at the clinic edge. External assurance is required to unite distributed-systems failure analysis with clinical traceability under real connectivity constraints.

What you will own

• Map case identity, consent, acquisition, preprocessing, local inference, human interpretation, queueing, transmission, specialist review and amendment evidence.
• Define signed provenance and version rules that remain inspectable when time, identity, policy or reference services are temporarily unavailable.
• Specify offline limits for diagnostic support, expiry, escalation, result display, human override and cases that must wait for connectivity.
• Design queue integrity, prioritisation, retry, duplicate detection, partial-transfer recovery and bandwidth-aware synchronisation controls.
• Establish conflict rules for local and central amendments without erasing chronology or presenting stale conclusions as current.
• Run conformance scenarios covering long disconnection, clock error, interrupted upload, duplicate case, changed consent, model rollback and device replacement.
• Deliver the assurance design, clinic kit, evidence examples, adoption gates, training needs and open clinical-policy decisions.

Candidate qualifications

• Designed store-and-forward or offline-first clinical systems where delayed synchronisation affected diagnostic or treatment evidence.
• Built end-to-end provenance across device acquisition, model execution, transformation, consent and human interpretation.
• Resolved duplicate, partial, stale or conflicting case histories under intermittent connectivity without relying on central timestamps alone.
• Worked inside medical quality, privacy and safety governance while distinguishing platform assurance from clinical efficacy validation.
• Conducted field tests with constrained bandwidth, power, skills and equipment rather than laboratory connectivity assumptions.
• Delivered conformance material that clinic and engineering teams could execute without ongoing consultant interpretation.

Non-negotiables

• Can complete four East African clinic visits and all panel reviews within the fixed three-month engagement.
• Will handle clinical material only through approved de-identification and controlled-access arrangements.
• Brings deployed offline diagnostic or comparably safety-critical edge evidence; generic mobile synchronisation alone is insufficient.
• Accepts clinic-executed conformance scenarios and traceable case histories as final acceptance requirements.
