From Risk Prediction Models to Risk Assessment Service: A Formulation of Development Paradigm.

Risk assessment services fulfil the task of generating a risk report from personal information and are developed for purposes like disease prognosis, resource utilization prioritization, and informing clinical interventions. A major component of a risk assessment service is a risk prediction model. For a model to be easily integrated into risk assessment services, efforts are needed to design a detailed development roadmap for the intended service at the time of model development. However, methodology for such design is less described. We thus reviewed existing literature and formulated a six-stage risk assessment service development paradigm, from requirements analysis, service development, model validation, pilot study, to iterative service deployment and assessment and refinement. The study aims at providing a prototypic development roadmap with checkpoints for the design of risk assessment services.
