being missed. There is also some literature showing associations between the demographic characteristics of GPs and the rate of identification, but no research of this kind has been done in Australian general practice. Methods: This presentation reports on baseline data collection in a multisite GP dementia study in Australia. One hundred and fifty four GPs audited 1822 of their patients aged 75 years and over to identify cases of no, possible, probable or definite dementia. Patients were subsequently examined by a research nurse, and assigned to dementia or no dementia using a cut -off of less than 81on the CAMCOG interview. This presentation examines a range of GP characteristics in relation to GP accuracy in identifying dementia. Results: Overall GPs agreed that patients had possible, probable or definite dementia in 71 (45%) of 157 patients with CAMCOG identified dementia. GPs also agreed with the CAMCOG in identifying 1507 (90.5%) out of 1665 as not having dementia (kappa 1⁄4 0.296). Overall of 1161 patients seen by male GPs, 40 (39.6%) of 101 with CAMCOG dementia were identified by the GP as possible, probable or definite dementia. Of 550 patients seen by female GPs, 25 (54.3%) of 46 with dementia were identified as above. Younger GPs were more likely to identify dementia than older GPs, with identification rates in agreement with CAMCOG dementia ranging from 50% in the 40-49 age range to 21.7% in the 60+ age range for GPs. Solo GPs identified 24% of patients with dementia in agreement with the CAMCOG whereas GPs in larger practices identified 48.3% of these patients as possible, probable or definite dementia. Multivariate analysis will be reported. Conclusions: In our study of 154 Australian GPs, univariate analysis shows that GPs who are male, older and solo practitioners have lower agreement with the CAMCOG in identification of dementia than female GPs or those that are younger and work in larger practices.
