Background: MedicineInsight is a primary care quality improvement initiative from NPS that was established in 2011. Currently MedicineInsight collects de-identified patient information from over 500 participating general practices across Australia to create a longitudinal database of over 3.5 million anonymised patients. Whilst most chronic kidney disease (CKD) patients are identified and managed in Australian general practice the extent of this population and their correlated background characteristics, based on a large general practice dataset, has not been described.

Aims: To provide an estimate of the incidence of CKD, and the prevalence of CKD (stages 3, 4 and 5), in Australian general practice based on routinely collected electronic record data. To examine the influence of patient characteristics such as gender, age, rurality, identification as an Aboriginal and/or Torres Strait Islander person, smoking status, and major comorbidities on the stage of CKD.

Method: Medicine insight data 01/01/2013 to 01/06/2016 was used to identify CKD (stages3, 4 and 5). The group of patients meeting the inclusion criteria of at least two eGFR results of < 60ml/min/1.73M2 at least 90 days apart, were identified and their characteristics and comorbidities correlated.

Results: Of 1,483,416 patients, 61,102 (56% female) met the inclusion criteria for CKD (stages 3, 4 and 5) (4.1% overall). Of these 28% were ≤ 70 yrs,14% lived in outer regional or remote locations, and 5% were smokers. Our presentation will reveal the correlations found.

Conclusion: Australian general practice routinely collected electronic record data provide a valuable primary care-based addition to the dataset on chronic kidney disease. It is likely to prove useful in describing other major disease groupings as well, and also in painting a more accurate description of the complex comorbidity managed by Australian general practitioners.
