nformation technology offers the potential for substantially improving work performance. The response of health care professionals to the use of health information technology such as the electronic medical record is an important component that can explain the success or failure of any health information technology application. This study sought to assess the behavioural intention of users’ in public health facilities to implement electronic medical records (EMR) using the Kiambu County hospital as a case study. The constructs used were those proposed by the technology acceptance model (TAM) and included perceived usefulness, perceived ease of use, attitude and performance expectancy. The study adopted a cross sectional research design with the target population constituting 130 medical, paramedical and administrative staff expected to use the EMR. Stratified random sampling technique was used based on categories of the staff establishment. Primary data was collected using structured questionnaires and analyzed using SPSS to generate descriptive and inferential statistics to describe study results. The study found that the health workers intended to use the EMR once it is deployed for use.. The study concludes that behavioural intention to use the electronic medical records was found to be positively influenced by the perceived ease of use, perceived usefulness, attitude towards and the performance expectancy of the EMR. The study recommends that public hospitals management should train their employees on the information systems prior to the EMR adoption in order to ensure successful implementation.
