Medical clinics expanding care to needy

Despite an increasing number of free medical clinics, treatment is hard for the needy to track down. That's especially true for the nation's top health problems--high blood pressure, diabetes and high cholesterol--that require ongoing care even when the person feels no symptoms if they're to avoid heart attacks, strokes, kidney failure and amputations. Clinics require a special trip, a long wait, perhaps a baby sitter, annoyances for the well-to-do but huge obstacles for someone who must take three buses to reach the doctor or who loses a day of pay for the time off.
