Knowledge and attitudes of health care workers about AIDS and HIV infection before and after distribution of an educational booklet.

Hospital workers (509) in a health authority were surveyed, and asked if they were in contact with HIV positive or AIDS patients; about their perception of risk; of their knowledge about and attitudes towards HIV and AIDS problems at work; and their desire for more information about AIDS and HIV. Overall scores for level of knowledge and attitudes were calculated; clinical workers scored better than non-clinical workers. Following the first survey, an information booklet was distributed to all health authority staff and after distribution, 232 staff were surveyed again. In this group (the follow-up group), there was a reduction in perceived risk, an improvement in the level of knowledge and in attitudes, and a reduction in the desire for further information. The group who initially had the least level of knowledge and most unfavourable attitudes (non-clinical workers) were the group who improved most.
