We laud the authors of a recent CMAJ article for their usable framework for the development and adoption of machine-learned solutions1 and propose that this will be useful to guide the use of machine learning in paramedicine. Paramedic clinical decision-making is well positioned to benefit from machine learning, given the prevalence of large paramedic data repositories in Canada. These data repositories are not just large, but are rich in structured patient data features (i.e., clinical, nonclinical, administrative), such as primary complaint, medications, detailed physical assessments, vital signs (including cardiac monitoring), physiologic scores, paramedic interventions and time stamps to encode a sequence of events. These are ideal conditions to construct accurate prediction models. Given that paramedics need to make accurate clinical decisions when patient presentations are complex, machine learning algorithms could inform point-of-care treatment and more appropriate transport destinations besides emergency departments (EDs). To test the accuracy of machine learning algorithms in predicting future patient outcomes while in the prehospital field, the integration of paramedic and hospital ED data is required. Assembling and housing integrated data are barriers, but could be overcome if paramedic services partner with data scientists and data centres.
