Who We Are

AMDA – The Society for Post-Acute and Long-Term Care Medicine is the only medical specialty society representing the community of medical directors, physicians, nurse practitioners, physician assistants, and other practitioners working in the various post-acute and long-term care (PALTC) settings. The Society’s members work in skilled nursing facilities, long-term care and assisted living communities, CCRCs, home care, hospice, PACE programs, and other settings.

The Society has two affiliate organizations. The American Board of Post-Acute and Long-Term Care Medicine runs a certification program for medical directors in PALTC, credentialing Certified Medical Directors (CMDs). The Foundation for Post-Acute and Long-Term Care Medicine oversees awards, community outreach, education, and research with the mission to advance the quality of life for persons in PALTC through inspiring, educating, and recognizing future and current health care professionals.


A world in which all post-acute and long-term care patients and residents receive the highest-quality, compassionate care for optimum health, function, and quality of life.


We promote and enhance the development of skilled, compassionate, and committed medical practitioners, clinicians, and leaders to provide person-centered, goal-concordant care across all post-acute and long-term care settings.

Dedicated to defining and improving quality, we advance our mission through timely interprofessional development, evidence-based clinical guidance, and steadfast advocacy on behalf of members, patients and residents, families, and staff. 


The American Medical Directors Association (AMDA), was officially chartered in June, 1977, when Dr. James Pattee (as the AMA's representative) and Mr. Herman Gruber (of the AMA Aging Committee staff) went to Hilton Head, South Carolina, to swear in Dr. William Dodd as founding president of the organization.

Dr. Dodd, a family practitioner based in Macon, Georgia, recognized the need to organize and educate physicians who would fulfill the role of the physician medical director created by federal mandate in 1975.

The association stayed in Georgia until 1988, when it moved to the Washington, DC area, where it could better influence the momentous changes in nursing home reform ushered in by the passage of OBRA '87. Indeed, AMDA commented on virtually every regulation stemming from the OBRA '87 legislation. This increased activity in national public policy began a period of membership building that attracted younger primary-care physicians who were becoming increasingly involved in long-term care.

Building on this early history, the association has grown to become a recognized source of expertise on clinical practice and physician leadership in PALTC. The Society's Clinical Practice Guidelines (CPGs), for example, are referenced in the CMS State Operations Manual, and AMDA’s 22 evidence-based CPGs are considered the standard processes of care in the nursing home setting.

In 2014, the Society House of Delegates voted to change the organization’s name to AMDA – The Society for Post-Acute and Long-Term Care Medicine. This was done (a) to better reflect how the PALTC field has expanded to include all settings across PALTC from skilled nursing to home care and hospice; (b) to recognize that, while the Society's historical focus has been on nursing home medical direction, the society has always represented the full interprofessional practice team in PALTC, including attending physicians, nurse practitioners, physician assistants, and others. Along with the name change, the House voted to expand general (i.e., voting) membership to include nurse practitioners and physician assistants.
