Abstract: Health Care Assistants (HCA) are trained to assist nurses in both direct and indirect patient care activities. As they involve in direct patient care, their knowledge of infection control precautions must be a fundamental requirement. An evaluation study, using quasi-experimental design, was conducted to find out the infection control knowledge and handwashing practice of all the HCAs using questionnaires before and after an education programme. Ninety HCAs completed the questionnaires. In addition, observations on the compliance and appropriateness of handwashing were carried out in all wards with HCAs using work sampling method. The data collected by questionnaires were compared using t-test and one way analysis of variance. Data analysis showed that the educational intervention led to a significant increase in total score on the knowledge questionnaire. For observations, chi square test was used to compare the handwashing compliance. Though the result was not statistically significant, the compliance rate was slightly higher in the subsequent observations. HCAs tended to wash their hands less in 'less dirty' tasks. A scoring system was used to assess the handwashing technique. Chi square test showed no significant difference in score obtained before and after the intervention, but more proper handwashing technique was demonstrated in the subsequent observations, p<0.03. Recontamination of hands after handwashing was common as the subjects used to turn off the tap by clean hands. The educational programme only increase the subjects' understanding of infection control, but to improve the compliance, more effort is required. Staff awareness, understanding of infection control and adherence to the established preventive practices are factors that may influence the successful implementation of infection control programme. The need for staff education in infection control and the need to increase staff compliance with infection control measures must not be neglected in clinical practice. Nurses should be more aware of their own importance as role models for other health workers.
