This review of residency and fellowship programs across several health professions includes the development of residency programs and the implications these developments have on occupational therapy. The analysis across health professions includes medicine, pharmacy, physical therapy, speech-language pathology, and occupational therapy. This thorough analysis can help guide the development of occupational therapy fellowships. This background provides a foundation to focus on the implications for emerging fellowships within occupational therapy. The findings can be utilized to assist in the development of new successful fellowship programs.
