I used to be an ACLS instructor. I wanted to be an instructor so I'd never have to go through the course again!
I hated it when they "dumbed down" the standards. Not that I wanted to make people sweat or stress, but they knew they were going to pass, so they didn't bother to be prepared. ICU nurses who didn't know the difference between adenosine and verapamil. It was a joke having them identify the rhythm, because they knew which algorithm I was teaching and which rhythm went with it. Mega-code was too much, but this was not enough.
Then the people running the course were so anxious to have the entire program done before lunch, they would stick their head in every five minutes to ask if I was done with my group. No time to teach, no time to evaluate whether anyone understood the algorithms. I don't think you can check off twenty people in fifteen minutes, and teach the algorithm with any degree of competence. I was told I was too slow and I should be like another instructor. Except that I found out that instructor was so disgusted with being told to hurry up that she would just sign everyone's sheet that they passed and send them out the door. ACLS isn't meant to be completed in three hours.
I wanted to teach through another facility, but the first facility wouldn't issue my card (showing I was current in my teaching requirements), and the second facility wouldn't accept me without the card. I don't teach ACLS any more, so maybe things have changed. I understand the standards were once again revised.
