Increasing use of general practice management and team care arrangements over time in New South Wales, Australia.

The number of older people living with chronic health conditions is increasing in Australia. The Chronic Disease Management (CDM) items program was introduced to the Medicare Benefits Schedule (MBS) to encourage a more structured approach to managing patients with chronic conditions. Initial uptake was slow and recent research has suggested that uptake is decreasing. This paper examines: person MBS CDM claims in NSW between 2006 and 2014 - using baseline survey data (2006-09) from the Sax Institute's 45 and Up Study linked to MBS and Death Registry data (2006-14) - and MBS CDM claims per 100000 population - using billing data sourced from the Medicare Australia Statistics website - to systematically examine any changes in uptake using a time-series analysis. After age adjustment, claims for initial plans increased from 11.3% in 2006 to 22.4% in 2014. Increases were also seen for allied health service claims (from 4.1% in 2006 to 20.8% in 2014) and for plan reviews (from 5.9% in 2006 to 16.0% in 2014). These increases were consistent with the MBS summary claims data. There is evidence that these plans are appropriately targeting those in most need; however, there is limited evidence of their effect. Claims for plan reviews, although increasing, are suboptimal and may indicate poor continuity of care.
