Global Rating Assessment of Skills in Intraocular Surgery (GRASIS)

Objective: The American Board of Ophthalmology in conjunction with the Accreditation Council for Graduate Medical Education has mandated the systematic assessment of surgical competence of ophthalmology residents at all residency programs. We present a tool complementary to the Objective Assessment of Skills in Intraocular Surgery (OASIS) to assess residents' surgical competence. Participants: Twenty experts in resident education, including the chiefs of all ophthalmology services and the chief resident at the Harvard Medical School Department of Ophthalmology. Methods: A 1-page subjective evaluation form was developed in conjunction with the Objective Assessment of Skills in Intraocular Surgery evaluation form to assess the surgical skills of residents. A panel of surgeons at the Harvard Medical School Department of Ophthalmology at the Massachusetts Eye and Ear Infirmary reviewed the form and provided constructive feedback. Results: Experts' comments were incorporated, establishing face and content validity. Conclusions: The Global Rating Assessment of Skills in Intraocular Surgery (GRASIS) has face and content validity. It can be used to assess a resident's surgical care of patients as well as a resident's surgical knowledge, preparedness, and interpersonal skills. Reliability and predictive validity will be determined at our institution. We believe the GRASIS evaluation form will be a valuable tool in conjunction with the OASIS evaluation form for assessing ophthalmology residents' surgical skills at other residency programs as well.
