The primary care workforce shortage will be magnified by the growing elderly population and expanded coverage as a result of health care reform initiatives. The pharmacist workforce consists of community-based health care professionals who are well trained and highly accessible, yet underutilized. Some health care professionals have advocated that primary care teams should include pharmacists with complementary skills to those of the physician to achieve quality improvement goals and enhance primary care practice efficiencies. New primary care delivery models such as medical homes, health neighborhoods, and accountable care organizations provide opportunities for pharmacists to become integral members of primary care interdisciplinary teams.
