ABSTRACT
OBJECTIVE: To investigate the cognition status of construction workers on occupational health knowledge.METHODS: Seven hundreds and sixteen construction workers in Luzhou City were selected by cluster sampling method.Their cognition conditions on occupational health knowledge were investigated. RESULTS: The awareness rate of legal knowledge of occupational disease was the highest in construction workers in Luzhou City,which was 51. 68%. However,the awareness rate of legal compensation system of occupational disease was the lowest,which was only 5. 59%. The main sources of workers getting to know about occupational health knowledge were television, network and newspaper( accounting for 70. 25%). With the decrease of age and the increase of educational level,the awareness rates of occupational health knowledge in construction workers had a tendency of increase( P < 0. 05). The awareness rates of legal knowledge and diagnostic programs of occupational disease and legal compensation system in workers with special rates types of work were higher than those of handymen and traditional craftsmen( P < 0. 05). The awareness rates of occupational health knowledge in workers who had received the training of occupational safety and related occupational disease knowledge were higher than those who had not( P < 0. 05). The multivariate logistic regression analysis results showed that factors influencing the awareness rates of occupational health knowledge of construction workers were the educational level,type of work,the training of occupational safety and related occupational disease knowledge( P <0. 05). CONCLUSION: The awareness rate of occupational health knowledge in construction workers was generally low. The training of occupational safety and related occupational disease knowledge should be strengthened for the construction workers.
ABSTRACT
BACKGROUND: Sharps injuries remain a common factor in occupational exposure of healthcare workers to blood-borne viruses. The extent to which the introduction of safety-engineered devices has been effective in reducing such injuries among healthcare workers is unclear. AIMS: To investigate the incidence of sharp object injury among healthcare workers in the Capital Health Region of Alberta, Canada and to determine the effectiveness of the introduction of safety- engineered devices in preventing these. METHODS: All reports of sharp object injuries to Capital Region Workplace Health and Safety offices from healthcare workers 2003-10 were analysed. Rates of sharp object injury were compared before (2006), during (2007-08) and after (2009-10) the introduction of safety-engineered devices, adjusting for other potential risk factors using Poisson regression and log-linear models. RESULTS: Between 2003 and 2010, a total of 4707 sharp object injuries were reported from 15 healthcare facilities. The sharp object injury rate per 1000 full-time equivalent employees per year declined from 35 before the introduction period to 30 during the introduction period (rate ratio [RR]: 0.88, 95% confidence interval [CI]: 0.78, 0.99) among most healthcare workers, but then rebounded again slightly after the intervention. Physician risks showed little change during the period of introduction (odds ratio [OR]: 0.99, 95% CI: 0.85, 1.14) but decreased significantly after the intervention (OR: 0.83, 95% CI: 0.71, 0.97). CONCLUSIONS: The introduction of safety-engineered devices was associated with a modest reduction in reported sharp object injuries but this appeared to be relatively short-lived for most workers.
