Applied at large hospital for Unknown

I had a great first round interview with a large hospital in NYC, and they quickly moved me to an on-site interview where I met with about 8-9 different people. Everything seemed to go well, and I felt positive about my performance. However, it's now been 9 days since the on-site, and I'm starting to feel anxious. I followed up after 7 days but haven't received a response yet. The HR team was very prompt in their communications before, which adds to my concern. I know that 9 days isn't a long time in the hiring process, but I'm starting to wonder when I should really start worrying about the lack of communication.
