If it's part of an HMO, definitely. That's been the case in HMO since the 80's as business management practices pushed in after being bought.
If you have the option of PCP/PPO, they may still be rushed, but it's more because they're trying to see as many patients as they can, not because upper management is pushing them to meet statistics (only some PPO docs are part of a group that uses such management, independent docs don't have that pressure, unfortunately there's a lot of pressure against independent docs by both insurance and government these days).
Since the 80's I've chosen HMO and PCP options through the same insurance provider (in multiple states), and the difference is obvious. HMO GP's are clearly pressured to reduce office time, and only provide options that patients push for, while PCP docs will put options on the table and let you choose what route to go.
