Background. When selecting predictive tools, clinicians and healthcare professionals are challenged with an overwhelming number of tools, most of which have never been evaluated for comparative effectiveness. To overcome this challenge, the authors developed and validated an evidence-based framework for grading and assessment of predictive tools (GRASP), based on the critical appraisal of published evidence. Methods. To examine GRASP impact on professionals decisions, a controlled experiment was conducted through an online survey. Randomising two groups of tools and two scenarios; participants were asked to select the best tools; most validated or implemented, with and without GRASP. A wide group of international participants were invited. Task completion time, rate of correct decisions, rate of objective vs subjective decisions, and level of decisional conflict were measured. Results. Valid responses received were 194. Compared to not using the framework, GRASP significantly increased correct decisions by 64 objective decision making by 32 decision making; based on guessing and based on prior knowledge or experience by 20 significantly decreased decisional conflict; increasing confidence and satisfaction of participants with their decisions by 11 13 (T=-0.87, p=0.384). The average system usability scale of GRASP was very good; 72.5 Using GRASP has positively supported and significantly improved evidence-based decision making and increased accuracy and efficiency of selecting predictive tools.
