Research findings, engineering deep-dives, clinical insights, and lessons learned from building the platform that tracks sickle cell patients across Africa.
Internet connectivity in rural Nigerian health facilities averages just 34%. We built Tracka with offline-first architecture to ensure that field agents never lose a single patient record, even in the most remote communities.
Our data reveals significant variations in sickle cell genotype distribution across Nigerian states. SS genotype accounts for 65% of tracked patients, but the ratio shifts dramatically in the southeast where SC prevalence reaches 28%.
Analysis of 8,400+ sickle cell patients shows that consistent hydroxyurea adherence reduces crisis frequency by an average of 44%. But adherence rates vary dramatically by region, age group, and access to medication.
When a patient visits three different facilities across two states, how do you prevent three separate records? Our fingerprint hashing algorithm combines six data points to identify duplicates with 99.2% accuracy.
We launched the Tracka Data API to make anonymized, aggregated sickle cell data accessible to researchers worldwide. In the first three months, 47 research organizations have integrated our data into their studies.
Deploying technology in African health facilities is nothing like a typical SaaS rollout. Shared devices, intermittent power, varying digital literacy, and complex organizational hierarchies all demand a different approach.
