Developing an Intervention for Safe Hospital Insulin Use for Older Adults With Diabetes Undergoing Surgical Admission (SHINE Study): A Co-Design Study.

People with diabetes with recent lived experience of surgical hospital admission were integrally involved as co-designers and decision makers in this study. They contributed towards interpretation and analysis of findings through discussion, feedback and validation in workshops and through means accessible to them. They were decision makers in the identification of priorities for intervention development and in identifying and validating the content of the toolkit developed.
