Sounds like a great opportunity for a digital checklist with a computer vision, audio analysis component and deep learning backend that could quantify, and eventually automate the adherence to such checklists.
I wonder how many people would actually follow the checklist if they knew their compliance was being continually monitored and audited?
I think that misses one of the lessons of the study: people need to be invested in the checklist for it to help. In other words, they need to want to go through the process. The checklist itself is not magical. When it's effective, it's because it formalizes everyone's desire to adhere to agreed-upon protocols that everyone agrees are beneficial.
Even though it seems clear that the checklist itself has to be well designed, I don't think it's a bad idea to ensure they are followed. Strategies like the one the OP proposed are independent from checklist quality.
Well, you actually just need an Alexa there reciting the checklist and waiting from a yes before moving to the next item.
Since it is intended to be in a hospital, that's a $40K Alexa that must be created by somebody with the right connections. But all that you need is an Alexa.
