Methods and apparatus for visually creating complex expressions that inform a rules-based system of clinical decision support

摘要

A method of constructing a Boolean expression in a clinical setting, including identifying at least a first and a second data assertion to add to the Boolean expression, adding at least one Boolean logical operator to the Boolean expression, determining an order of evaluation for the first and second data assertions, and visually depicting the first and second data assertions and the Boolean logical operator in a hierarchal display.
