Introduction: Cardiovascular disease (CVD) and cancer are leading causes of death globally. Early detection of cancer and risk factors for CVD may improve health outcomes and reduce mortality. General practitioners (GPs) are accessed by the majority of the population and play a key role in the prevention and early detection of chronic disease risk factors. This cross-sectional study aims to assess the acceptability of an electronic method of data collection in general practice patients. The study will describe the proportion screened in line with guidelines for CVD risk factors and cancer as well as report the prevalence of depression, lifestyle risk factors, level of provision of preconception care, cervical cancer vaccination and bone density testing. Lastly, the study will assess the level of agreement between GPs and patients perception regarding presence of risk factors and screening. Methods and analysis: The study has been designed to maximise recruitment of GPs by including practitioners in the research team, minimising participation burden on GPs and offering remuneration for participation. Patient recruitment will be carried out by a research assistant located in general practice waiting rooms. Participants will be asked regarding the acceptability of the touch screen computer and to report on a range of health risk and preventive behaviours using the touch screen computer. GPs will complete a one-page survey indicating their perception of the presence of risk behaviours in their patients. Descriptive statistics will be generated to describe the acceptability of the touch screen and prevalence of health risk behaviours. Cohen's κ will be used to assess agreement between GP and patient perception of presence of health risk behaviours. Ethics and dissemination: This study has been approved by the human research committees in participating universities. Findings will be disseminated via peer-reviewed publications, conference presentations as well as practice summaries provided to participating practices.
