Sedein — Healthcare Platform.

Context

Sedein supports a community of cancer patients in Colombia. The team — doctors, social workers, and administrators — was tracking patient activity, treatments and follow-ups across spreadsheets and paper. Patients were falling through the cracks: missed appointments, incomplete treatment cycles, no early warning signal for adherence drops.

The platform's job was to make the work of the medical team faster, not glamorous. If the system felt like extra paperwork, no one would use it.

Constraints

Doctors had no time for training. Data was sensitive (regulated). Several workflows had to integrate with existing hospital systems that exposed only legacy APIs. The pilot had to run in real clinical hours without disrupting patient care.

Approach

I sat with the medical and admin teams during real shifts to map the actual flow — not the flow they described in meetings. The gap was significant: most of their time was spent reconciling data between three systems, not on patient care.

Hypothesis: if we shortened the reconciliation work, adherence would improve as a side effect (more time for follow-up calls).

Solution

A Big Data pipeline aggregated treatment events to surface adherence risks early. Social workers received a weekly worklist — patients ranked by risk of falling out of treatment.

Outcome

Treatment adherence reached 97% after the first year. Administrative time per patient dropped 40%. Adoption inside the team grew 80% as the platform replaced the reconciliation spreadsheets entirely.

Reflection

The lesson I keep using from this project: in regulated environments, the UX you design must compete with paper and spreadsheets, not with consumer apps. If your platform is heavier than the workaround, no one will use it.

I wish I had pushed harder for offline support. Some clinics had unstable connectivity and a small number of records still got entered after-the-fact in paper.
