Procedures most often planned to be added by respondents included flexible sigmoidoscopy (59%), colposcopy (30%), endometrial biopsy (23%), pulmonary function test (18%), smoking cessation groups (16%), exercise tolerance test (14%), and fine-needle aspiration biopsy (14%). Forty-two percent of respondents volunteered to teach these procedures to their colleagues., Conclusions: Family practice includes a wide variety of procedures used in diagnosis, screening, and prevention.
