Patient decision aid

NICE guidelines give advice to healthcare professionals on the care and support that should be offered to people who use health and care services. Individual people have the right to be involved in discussions and make informed decisions about their treatment and care with their healthcare team. They should be given relevant information that explains the treatment and care in a way they can understand. For more information see your care.

This patient decision aid can help adults with type 2 diabetes think about their options for controlling their blood glucose to try to reduce the long-term risks of diabetes. It is intended to help adults with type 2 diabetes who:

  • have been taking a single medicine to control their blood glucose (HbA1c) level and
  • their HbA1c level is higher than the target level they had agreed with their healthcare professional.

It summarises information on the things people in this situation most often want to think about and discuss with their healthcare team when they are deciding on:

  • what new target HbA1c level is best for them and
  • which medicines they might try to achieve this target.

It is intended to help a person making these decisions weigh up the possible advantages and disadvantages of the different options.
