A move away from rigid target based CBG control is advised, especially avoiding the use of rapid acting insulins if the CBG is ‘high’ in those T2DM or steroid induced diabetes. There is no evidence to show that the use of rapid acting insulins will offer any symptomatic benefit in this patient group. In these situations, an alteration to the existing diabetes regimen is preferable to ensure CBG readings are within the preferred range.
However, in patients with T1DM with a prognosis of longer than weeks, use of rapid acting insulins may avoid ketoacidosis, which would add significant burden of illness. Therefore patient selection, that encompasses type of diabetes and predicted prognosis, is crucial when considering prescription of PRN rapid acting insulin.
Frequency and method of testing is likely to need to change. Ideally, CBG monitoring should be minimised where possible. Urinalysis may be sufficient in some cases, particularly where there is no hypoglycaemia risk, or within the community where access to a CBG machine may be limited. Stopping CBG monitoring altogether may be a reasonable option for some patients. Refer to the Diabetes Management section for specific guidance depending on the type of diabetes and estimated prognosis.
Patients, families and carers will have often spent many years striving for tight glycaemic control in an attempt to reduce the risk of long-term complications. They may find it difficult to understand that when the end of life is approaching, maintenance of strict normoglycaemia, aggressive blood pressure and lipid management, and strict dietary restriction can become detrimental to quality of life.
Avoidance of long-term complications becomes an irrelevant goal.
They will require sensitive counselling from their clinicians to explain the shift in glycaemic goals.
End of Life Guidance for Diabetes Care (1) make note of certain clinical scenarios where special considerations may be necessary.
Please refer to End of Life Guidance for Diabetes Care (1) national document for further exploration of these scenarios.
This Guide is intended for use by healthcare professionals and the expectation is that they will use clinical judgement, medical, and nursing knowledge in applying the general principles and recommendations contained within. They are not meant to replace the many available texts on the subject of palliative care.
Some of the management strategies describe the use of drugs outside their licensed indications. They are, however, established and accepted good practice. Please refer to the current BNF for further guidance.
