This article introduces findings from the first phase of a randomized controlled trial of educational interventions in primary care. The focus of the article is the knowledge, attitudes and confidence of primary care nursing staff to the diagnosis and ongoing management of dementia. A total 78 nurses with a mean age of 46.4 years and a mean time since qualification of 23.0 years were recruited in 36 practices in central Scotland and in London. Disciplines represented by this sample were predominantly district nurses, health visitors, practice nurses and community staff nurses. Each practitioner was administered an extensive self-completion questionnaire before the educational interventions were introduced to measure baseline knowledge, confidence and perceived difficulties in dementia care management and attitudes. Results from the quiz indicate lower levels of knowledge about epidemiology and diagnosis, but slightly higher levels about management strategies. Self-reported ratings of confidence were also low and were directly related to ratings of difficulty in identifying dementia and dealing with coexisting behavioural and mental health problems. Lower scores on all domains were recorded for practice nurses than for district nurses or health visitors.
