This is a study which examines the effects of an educational program on Hispanic physicians' attitudes towards and knowledge of HIV/AIDS. The study also examines physicians' practice patterns related to the screening and testing of Hispanic patients at risk for the disease. A one on one educational program was taken to the physician's office at a time convenient to the physician. A pre- and post-test design is used with questionnaires developed for the study that assess self-reported data related to physicians' attitudes, knowledge and practice patterns. A convenient sample of physicians participated. This limited the generalizability of the results to other groups. However, it does point out that a training program can alter physicians' screening and testing practices as well as their attitudes towards clients with HIV/AIDS. This has implications for providers in remote rural areas or in medically underserved communities where access to formalized continuing education may be limited or offered at times not compatible with a busy practice. The study may suggest that one kind of training and education need to be planned and developed to facilitate provider participation. Perhaps, on line courses or programs might be most effective of providing this one on one approach.
