Delays in referral from primary to specialist care are a common issue in the clinical management of diabetic foot (DF) disease and are associated with worse clinical outcomes. One of the reasons for the delays may be the complexity of risk stratification, which can leave clinicians who are not specialised in the DF uncertain about when to refer patients for specialist assessment. This article illustrates how risk stratification can be simplified with the use of decision trees. Two decision trees are given as examples: one based on the risk stratification system of the Scottish Diabetes Foot Action Group and one based on the National Institute for Health and Care Excellence guideline. Decision trees can be used to facilitate correct risk stratifications and the referral of people with DF complications, and thereby hopefully contribute to improved outcomes for people with DF disease.
