If you plan to see a doctor anytime soon, here’s some advice: bring a good book.

According to a new report from healthcare consumer watchdog Vitals, the shortest average wait time to see a physician increased more than a full minute last year from 2011.

Alaska led all states in shortest average wait time in 2012 at 16 minutes, 28 seconds. That’s up from 2011, when Wisconsin set the pace the way with 15 minutes, 26 seconds.

Vitals came up with the list by looking at wait times from patients of over 870,000 doctors.
