Plain English summary of protocol
Background and study aims
People with type 1 diabetes often miss early warnings of falling blood glucose level. This is a major concern as it can cause the individual to collapse without warning (severe hypoglycaemia). This problem can be reversed by preventing glucose levels falling too low, but this can be difficult as high glucose levels can also be damaging. Severe hypoglycaemia can be prevented in most people while improving overall glucose control using modern insulin injections or an insulin pump. In this study, we plan to further test these treatments with a new glucose sensor which can detect low glucose levels. The aim of the study is to find the best way of managing and supporting all patients with hypoglycaemia in the future.
Who can participate?
Male or female participants aged between 18 and 74 years, who have type 1 diabetes mellitus and have experienced impaired hypoglycaemia awareness and have experienced an episode of severe hypoglycaemia.
What does the study involve?
The study will compare insulin pumps and multiple daily injections with or without continuous glucose monitoring. Participants are randomly allocated to receiving either multiple daily insulin injections or insulin pump therapy, with or without continuous glucose monitoring.
What are the possible benefits and risks of participating?
The education programme given is hoped to improve the participants' overall diabetes control for many years after the end of the study. Participants with impaired awareness of hypoglycaemia may be at risk of severe hypoglycaemia. However, all the study treatments are tailored towards strict hypoglycaemia avoidance. For participants receiving insulin pump therapy may be at risk of diabetic ketoacidosis if the insulin pump is not used correctly.
Where is the study run from?
Newcastle Upon Tyne Hospitals NHS Foundation Trust
When is the study starting and how long is it expected to run for?
The study began recruiting participants in 2010, and recruitment ended in June 2011. The study will be completed in August 2013.

Scientific title | A definitive randomised controlled trial (RCT) comparing optimised multiple daily insulin injection (MDI) and continuous subcutaneous insulin infusion (CSII) with or without adjunctive real-time continuous glucose monitoring for the prevention of recurrent severe hypoglycaemia |
Study acronym | hypo COMPASS |
Study objectives | This study asks whether, in people who have diabetes mellitus and suffer from impaired or altered awareness of low blood sugars (hypoglycaemia), it is possible to restore that awareness and therefore prevent severe hypoglycaemia by rigorously preventing the participants from having any episodes of hypoglycaemia without jeopardising their overall diabetes control and using existing technology. The study will be able to answer this by analysis of a validated quantitative questionnaire that will be used throughout the study. Please note that as of 25/10/2012, the anticipated end date for this study was updated from 31/07/2012 to 31/08/2013. |

Health condition(s) or problem(s) studied | Type 1 diabetes mellitus |
Intervention | All participants will participate in an educational programme which has been validated in our single centre pilot study. This includes carbohydrate counting, discussion on glycaemic indices of food, the effect of exercise on blood glucose, the importance of detection and prevention of nocturnal hypoglycaemia and recommendations on carbohydrate administration for blood glucose less then 4 mmol/l. Thereafter participants will be randomised to one of four intervention groups for the 24 week intervention period. The four groups are as follows: 1. Multiple daily subcutaneous insulin analogue injections (MDI). Insulins used will be insulin glargine and insulin aspart. 2. MDI using aspart and glargine with real time continuous glucose monitoring 3. Continuous subcutaneous insulin infusion (CSII) using insulin aspart 4. CSII using insulin aspart with real time continuous glucose monitoring Participants will be followed up monthly during the 24 week intervention period after which they will be followed up at 6, 12 and 18 months. All diabetes care after the 24 week intervention period will return to routine NHS care.
