During the last meeting of a San Mateo County committee looking into the issue of finding ways to provide affordable health care for uninsured adults, one member of that body provided a rather startling prediction. Robert Merwin, representing Mills-Peninsula Health Services, said it is estimated that the region will lose 120 primary care physicians within the next five years. Their patients would represent about one-third of the county’s total population. So one big concern is that, if those general practitioners are not replaced, both the insured and the uninsured would face a distinct lack of family doctors on the Peninsula no matter what solutions for the latter are found. Not a pleasant thought at all.
