Many studies have documented nurses' attitudes and concerns regarding AIDS/HIV, but little is known about Taiwanese nurses. We documented attitudes, concerns, gloving practices and practical AIDS/HIV knowledge of 1090 nurses from one metropolitan hospital in Changhua City, Taiwan. The response rate was 80.9%. Both HIV and hepatitis contraction in the workplace was nurses' main concern. Two hundred and ten nurses (19.3%) were seriously considering leaving nursing because of fear of contracting AIDS/HIV. Virtually all nurses considered it their right to be informed of the presence of HIV-positive patients in their direct work area and many believed that HIV testing of patients should be mandatory. Practical AIDS/HIV knowledge was deficient. These Taiwanese nurses have concerns and fears that might be related to deficiencies in practical AIDS/HIV knowledge. Continuous educational programmes are recommended to alleviate these nurses' attitudes and concerns regarding AIDS/HIV.
