Abstract
A novel and reusable software architecture was developed for productionizing a hospital
trauma team activation model built in MATLAB. Previously, models were prototyped in
MATLAB, then reimplemented, retrained, and retuned in Python and revalidated for
deployment. This new architecture directly deploys the MATLAB model, expediting the release
timeline and reducing cost. The roadblock preventing direct deployment of MATLAB models up
to this point has been MATLAB’s incompatibility with mobile ARM CPUs found in
smartphones and tablets. This new architecture uses a server with an x86-64 CPU to conduct all
model computations in a MATLAB instance running on the server, rather than attempting to
transplant the MATLAB model to mobile devices. It leverages a RESTful API on the server to
accept prediction requests containing validated and formatted patient data, and the Java Engine
API to interact with the MATLAB Engine in which the model is run on the patient data. Three
frontends, two apps and a website, accept patient data in a form containing number fields and
selectable options, send prediction requests to the RESTful API upon form completion, and
display the model output and corresponding activation recommendation to the user.
