As a nurse, Danielle Hatfield knows her way around the health care system. Living with diabetes and arthritis, she also frequently uses the system as a patient. Lately, she’s run into hurdles finding doctors. Endocrinologists have placed her on long waitlists, some running two years. Rheumatologists haven’t had appointments available for months. Then her young stepdaughter, with her own complex health needs, had her long-time primary care provider leave the practice, forcing them to search for a new doctor.
