A survey of nurses' knowledge, opinions, and reported uses of the Body Substance Isolation system.

The Body Substance Isolation (BSI) system was implemented at the University of California San Diego Medical Center in May 1987. About 2 years later, an evaluation was done of the long-term effects of BSI education and training on the knowledge, attitudes, and reported behaviors of nursing personnel. In June 1989, a questionnaire was sent to 600 nursing personnel, including all 100 nurses in the 20-bed surgical intensive care unit, all 66 charge nurses, and a random sample (434) of the remaining nursing staff (about 1000). Results from the 190 respondents (a response rate of 32%) indicated an understanding of the two purposes of BSI: (1) to reduce nosocomial infection risks to patients and (2) to reduce health care workers' risks of acquiring infections from patients. Over half of the respondents reported handling more than 11 needles per day and nearly half reported recapping contaminated needles two-handed "sometimes or often." Only 54% of the respondents reported they had received hepatitis B vaccine. Although more than two-thirds of the respondents had worked at the University of California San Diego Medical Center during the entire BSI system training, implementation, and follow-up period, there is still room for improvement in knowledge and use of the system, including issues related to the safe handling of sharps.
