NCAHD was established in 2007 in partnership with the Edward Via College of Osteopathic Medicine (VCOM) as a national research center with the mission to create national healthcare workforce datasets that was a quantifiably and quantitatively the highest quality data for the nation.

Other commonly used healthcare workforce data sources are either voluntarily updated (e.g. provider membership association data) or incomplete because they were never intended for use in healthcare workforce research (e.g. the National Provider Identifier)1-2 Therefore, we chose state licensure data as the base of our Enhanced State Licensure (ESL) data to which we integrate these and other data sources annually for the following providers:

  • Physicians: Allopathic and Osteopathic
  • Nurses: Advanced Practice Registered Nurses, Certified Registered Nurse Anesthetists, Certified Nurse Midwives, Certified Nurse Specialists
  • Dental: Dentists and Dental Hygienists
  • Other Specialists: Physician Assistants, Physical Therapists, Psychologists, Podiatrists, Optometrists, Pharmacists, Audiologists, Speech Language Pathologists, and Chiropractors

NCAHD’s mission is to provide data mapping and spatial analysis of either your data and/or our data warehouse of the nation’s most complete collection of physician and non-physician data, along with other demographic, socio-economic, and political data in support of your advocacy, healthcare education planning/expansion, research, and other healthcare workforce planning.
