Included in this guide is a suite of data indicators that can help focus resources on areas that will benefit from review (see using data to drive change and national therapeutic indicators).
Case studies provide examples of how to implement quality improvements prescribing in diabetes, using a person-centred approach.
Previous guidance considered variation between boards with regards to prevalence, cost and improvements in HbA1c. However newer agents can affect longer term outcomes, independent of HbA1c values, and therefore comparisons using the previous parameters are inadequate to show the whole system effect.
Diabetes prescribing accounts for 11.8% of the total medicines spend in primary care in Scotland (for the year to end March 2022).
The figure below shows the relative spend on diabetes medicines and classes. Click on the image to view a larger version. Boards should reflect on the relative split of this spend, considering therapies which have less evidence and/or effectiveness.

Additionally due to the complications of T2DM and co-morbidities, prescribing costs are attributable to management of hypertension, dyslipidaemia, diabetic neuropathy and others. People with diabetes have a significant impact on hospital resources (accounting for a greater proportion of beds) with more frequent emergency admissions and longer stays.12 Additionally individuals with T2DM, accounting for age, require twice as much support as those without T2DM.
Therefore, the reduction in whole system costs of managing secondary co-morbidities and complications will outweigh any short-term increase in medicines costs.
