Aims and objectives. To support policy planning for health, the barriers to the use of health information and computer technology (ICT) by nurses in Australia were determined. Background. Australia, in line with many countries, aims to achieve a better quality of care and health outcomes through effective and innovative use of health information. Nurses form the largest component of the health workforce. Successful adoption of ICT by nurses will be a requirement for success. No national study has been undertaken to determine the barriers to adoption. Design. A self-administered postal survey was conducted. Method. A questionnaire was distributed to 10,000 members of the Australian Nursing Federation. Twenty possible barriers to the use of health ICT uptake were offered and responses were given on a five point Likert scale. Results. Work demands, access to computers and lack of support were the principal barriers faced by nurses to their adoption of the technology in the workplace. Factors that were considered to present few barriers included age and lack of interest. While age was not considered by the respondents to be a barrier, their age was positively correlated with several barriers, including knowledge and confidence in the use of computers. Conclusions. Results indicate that to use the information and computer technologies being brought into health care fully, barriers that prevent the principal users from embracing those technologies must be addressed. Factors such as the age of the nurse and their level of job must be considered when developing strategies to overcome barriers. Relevance to clinical practice. The findings of the present study provide essential information not only for national government and state health departments but also for local administrators and managers to enable clinical nurses to meet present and future job requirements.
