Abstract

A method for automated assessment of aseptic techniques for compounding in a compounding hood includes collecting data capable of determining the position, orientation, and movement of objects used in the aseptic compounding task using sensors positioned in or around the compounding hood. The method further includes providing the data to an automated aseptic techniques evaluator. The method further includes identifying stages of the aseptic compounding task from the data using the automated aseptic techniques evaluator. The method further includes automatically detecting, by the automated aseptic techniques evaluator, errors occurring during at least some of the stages. The method further includes generating and displaying, by the automated aseptic techniques evaluator, an output indicative of the errors.
