4.1 Summary of main findings
We found a range of barriers and facilitators to implementing QCancer. The barriers identified were: the need for more consultation time; the possibility of unnecessary worry and anxiety generated by cancer investigations; over-referral and over-burdening of services; practitioner scepticism about the usefulness and effectiveness of the tool; lack of integration of the tool into general practice IT systems; lack of training for practitioners on the use of the tool; and the need to establish effectiveness of the tool before rolling it out in clinical practice. The facilitators included perceptions that the cancer risk assessment tool would: support decision-making, speed up the process of assessment and treatment, help to identify and modify health risk behaviours, and personalise care. These barriers and facilitators need to be considered when planning to implement the tool in primary care consultations.
