I've done Lean work for hospital new patient intake centers. When it comes to triaging patients in extremely homogenous centers, the real training period is a few months long (formally it's one month, but that's really just to learn your way around the computer systems). In disease centers where the patients are calling with heterogenous complaints, the formal training period is also a month, but everyone agrees the real training period is just about two years plus weekly meetings with docs to learn about how to triage that week's oddball/edge cases. I suspect 911 calls are no less complex than scheduling people for a doctor's appointment.
