Indsamling af data om global sundhed var en mangelfuld videnskab: Arbejdere vandrede gennem landsbyer for at banke på døre og stille spørgsmål. De skrev svarene ned på papirskemaer for siden at taste dem ind - og fra denne mangelfulde data ville lande tage enorme beslutninger. Datanørd Joel Selanikio taler os igennem den strøm af forandringer, som er sket inden for indsamling af sundhedsdata det sidste årti - først med Palm Pilot og Hotmail, og nu på vej ud i skybaserede løsninger.

Kimen til en big-data revolution inden for sundhedsvæsenet

For decades, global health relied on paper forms and manual data entry, leaving critical questions about disease, medicine, and even child mortality largely unanswered. In many countries, knowing how many children have been vaccinated requires months or years of door-to-door surveys, with stacks of forms often never processed. By harnessing cloud technology and simple mobile phones, data collection now happens in real time, empowering health workers to make informed decisions instantly. This shift shrinks timelines from years to minutes, turning scattered guesses into actionable knowledge.
