Who provided primary health care in rural areas beginning in 1925?

Mary Breckenridge is recognized for her significant contributions to providing primary health care in rural areas, particularly through the establishment of the Frontier Nursing Service in 1925. She was a pioneer in delivering maternal and child health care to underserved populations in the Appalachian region of Kentucky. Breckenridge's work was pivotal in addressing the considerable health disparities present in rural areas during that time.

Her focus on midwifery and family nursing not only improved access to care but also set the foundation for the role of nurse practitioners in primary care settings. By establishing a system that combined nursing care with community health education, she effectively increased the quality of health services available to these rural communities. This initiative was groundbreaking and has had a lasting impact on rural healthcare delivery models.

In contrast, the other individuals mentioned played important roles in healthcare and nursing, but their primary focus and contributions did not center specifically on rural primary health care services starting in 1925.
