To physician Larry Shore of My Health Medical Group in San Francisco, it's no surprise that patients give doctors low marks for time and attention. A doctor's impatience, though, is often driven more by economics than ego. Reimbursement rates for a primary care visit are notoriously low, and Shore laments the need to hustle patients in and out. A new poll by NPR, the Robert Wood Johnson Foundation and Harvard School of Public Health found about 3 out of 5 patients think their doctors are rushing through exams. That's nearly the exact same number as three decades ago. NPR's survey asked people the same questions as another poll did back in 1983. When it comes to time, there is a stubborn feeling that doctors are in too big of a hurry.
