Investigation of current cognition of occupational exposure to HIV in healthcare workers in Liuzhou, China

Abstract

To investigate the current cognition of occupational exposure to human immunodeficiency virus (HIV) and the personal occupational protection awareness in healthcare workers in Liuzhou, China. A total of 270 healthcare workers were selected from 10 hospitals in Liuzhou by stratified random sampling for a cross-sectional study. And a self-administered questionnaire of occupational exposure to HIV was designed to conduct a survey. The descriptive analysis of data was carried out by Excel. And a logistic regression analysis was done to analyze the effects of different factors on healthcare workers' cognition of occupational exposure to HIV using the statistical analysis software SPSS 19.0. A total of 260 usable questionnaires (96.3%) were returned. Among them, 220 healthcare workers (84.6%) had received the trainings on occupational exposure to HIV; 223 healthcare wofkers (85.8%) were aware of the rules and regulations on prevention of occupational exposure to HIV and the operation procedures in their hospitals. The healthcare workers who had not received the trainings or had not known the rules and regulations and the operation procedures were mainly from primary or secondary hospitals. A total of 106 healthcare workers (40.8%) had directly contacted patients' blood or body fluids; 154 healthcare workers (59.2%) were injured by sharp instruments, and most were hollow needle stick injuries (98/154, 63.6%). A total of 168 healthcare workers (68.08%) had better cognitive awareness of occupational exposure to HIV, and 76 healthcare workers (29.2%) had moderate cognitive awareness. Some healthcare workers had poor knowledge in the common sense of AIDS/HIV and occupational exposure to HIV, the personal protection awareness of occupational exposure, or the disposal measures after occupational exposure. The univariate analysis using chi-square test showed that occupation and professional title were significantly correlated with the cognition (P<0.05). The multivariate logistic regression analysis showed that the doctors (OR3.8; P<0.05), nurses (OR3.04, P<0.05), and laboratory technicians (OR=9.51, P<0.05) had better awareness compared with the others. The healthcare workers with a primary or lower professional title had poorer awareness compared with the healthcare workers with a higher professional title (OR=0.47, P<0.05). Healthcare workers have the risk of occupational exposure to HIT. They do not have comprehensive and systematic knowledge related to occupational exposure to HIV, and they have a high demand for training.
