The study utilized a cross-sectional design. Data was retrieved from the American Academy of Family Physicians fellowship training directory, including program names, areas of focus, program length, and program descriptions. The collected data was categorized and analyzed based on areas of focus and training duration. The program descriptions were also analyzed qualitatively using Nvivo12 software. A total of 532 programs were included in the study:295 programs (55.5%) were ACGME-certified, while 237 programs (44.5%) were not. The majority of programs, 468 (87.9%), were clinically oriented, while 64 programs (12.1%) were non-clinical. Among ACGME-certified programs, the largest number of programs were in sports medicine (121 programs), followed by geriatrics (52 programs). Among non-certified programs, the largest number of programs was in obstetrics (66 programs), accounting for 27.8% of all non-certified programs. Qualitative research found that fellowship programs were diverse, reflecting the societal demands of healthcare service. Moreover, a significant emphasis was placed on empowering teaching and research abilities.The family medicine fellowship programs in the United States cover a wide range of disciplines and meet both the professional interests of doctors and the needs of patients. As China continues to implement its tiered medical system, it can learn from the experience of the United States and develop general practice subspecialty training programs, thereby improving the service capacity of general practitioners and improve the quality of healthcare.
