Clinical Decision Support in Under-Resourced Health Systems

In a clinic seeing two hundred patients a day with two clinical officers, the costliest error is not misdiagnosis, it is queue order. A child with early sepsis waiting four hours behind routine consultations is the failure mode that kills. Structured triage support, driven by vitals and a short symptom set captured at intake, changes outcomes without asking a clinician to defer to a model on treatment.

Framing it this way also resolves the professional objection. Nobody is being told what to prescribe. The system is being asked to make sure the sickest person in the room is identified faster than an overloaded human can manage alone.

Any deployment that requires continuous connectivity will fail in a regional clinic. The design has to assume intermittent power, a single shared device, and hours of offline operation, with local inference and deferred synchronisation. If the tool stops working during a grid outage, staff abandon it permanently, not because it failed once, but because they cannot rely on it during exactly the shifts where they need it most.

Device choice follows from the same logic. Shared tablets get dropped, borrowed, and locked. Session design must assume a nurse picks up a device mid-encounter with no idea what the previous user was doing.

Clinicians do not evaluate these systems on aggregate accuracy statistics. They evaluate them on whether the recommendations matched their judgement in the first fifty patients they saw together. A tool that is subtly wrong on routine presentations loses credibility permanently, even if it would have caught a rare emergency.

That argues for conservative thresholds early, visible reasoning, and an explicit uncertainty state. A system that says 'insufficient information, escalate' is trusted. A system that always produces a confident answer is not.

Patient records leaving the facility without a lawful basis is not a compliance abstraction; it is a direct threat to the willingness of patients to disclose symptoms honestly. In-country hosting, minimal collection, and clear retention limits are part of the clinical design, not a legal annex added afterwards.

The practical rule we apply: if a field cannot be justified by a decision the clinician will make in the next twenty minutes, it does not get collected.
