Due to the relative lack of standardization in the fellowship application processes for musculoskeletal radiology, program websites are of paramount importance as application resources. This study evaluates the comprehensiveness of these websites and the potential effects of program ACGME accreditation, region, and size on website comprehensiveness. The websites of musculoskeletal fellowship programs listed on the Society of Skeletal Radiology website were assigned a validated comprehensiveness score based on the presence of 19 specific informative components pertaining to the program's characteristics. The correlations of comprehensiveness scores with program ACGME accreditation, region, and size were evaluated. A total of 90 musculoskeletal radiology fellowship program websites were reviewed, yielding a mean comprehensiveness score of 55.1% (10.5 out of 19 criteria). Only 3 of the 19 criteria-application information (88.9%), stand-alone webpage (87.8%), and affiliated hospital information (84.4%)-were present in more than 80% of all websites. Eleven criteria, most notably away rotation information (6.7% presence) and case log (0.0% presence), were absent from at least 50% of all websites. Program ACGME accreditation was correlated with significantly higher website comprehensiveness scores compared with non-accreditation (p = 0.087). There is lack of sufficient, useful information and standardization on the websites of MSK fellowship programs throughout the country. According to our review and analysis, addition of specific information regarding each fellowship program and implementing some type of standardization may optimize fellowship matching for both applicants and the programs.
