Diabetes in CMDHB and northern region: Estimation using routinely collected data

This report provides an estimate of the prevalence of diabetes in Counties Manukau and three other district health boards in the northern region. It uses three separate sources of routinely collected administrative data to identify individuals likely to have diabetes, during a two-year period (2006-2007). Laboratory monitoring test frequency and pharmaceutical prescription claim patterns in people with diabetes are reviewed. Medical and surgical hospital discharge data for people with diabetes are compared to discharge data for people without diabetes in 2007.
