The workflow shouldn't live in one person's head.
When a seasoned MA leaves, the rooming knowledge goes with her: which questions to ask, which counts to run, when to hold an injection. The next hire relearns it from scratch, and your notes get thinner while they do. PainFlow holds the protocol so the person running it can change without the quality dropping.
Replacing a departed MA runs roughly $14,200, and medical assistants are the #1 turnover role in ambulatory practices.
