Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to investigate the utility of a combination of structured nurse led intervention and the use of Freestyle libre in adults with type 2 diabetes who have suffered an episode of severe hypoglycaemia in terms of mortality, unscheduled healthcare contacts and quality of life.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

It is increasingly recognised that hypoglycaemia carries risk to individuals with all forms of diabetes. Research has shown high rate of mortality in those with type 2 diabetes following an episode of severe hypoglycaemia and a previous pilot trial conducted in the UK suggested that this could be improved by a structured nurse led intervention aimed at modifying glycemic therapy to avoid hypoglycaemia, instigating regular blood glucose monitoring and providing education to participants on common triggers for hypoglycaemia and how to avoid them.

In this trial, the investigators will randomise individuals with type 2 diabetes who have suffered an episode of severe hypoglycaemia requiring emergency service call out to two arms. One arm will receive standard of care/treatment as usual and the other will receive a structured nurse led intervention as well as the use of a flash glucose monitoring system, Freestyle libre.

Active participation in the trial for both arms will be a total of twelve months (with the main intervention months 0-6.) Participants electronic records will be analysed for death and unscheduled healthcare contacts for a total of two years after recruitment.

The primary outcome measure is mortality between groups. Secondary outcomes include the use of estimated HbA1c (a variable produced by the freestyle libre device) compared to laboratory HbA1c, quality of life measures, effects on glycemic control and the number of unscheduled healthcare contacts.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Randomised controlled trial (not blinded due to study design)
Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

Unable to mask participants and trailists due to study design.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard of care

Participants are returned to the care of their usual diabetes care provider following randomisation. They will donate blood and urine samples as well as completing diabetes specific questionnaires at 0 and 6 months. They will also wear a blinded glucose sensor (freestyle Libre PRO) for a two week period at month 6.

Group Type NO_INTERVENTION

No interventions assigned to this group

Intervention arm

Participants will be randomised at baseline. They will provide blood and urine samples at months 0 and 6 as well as fill in diabetes specific questionnaires. They will receive education surrounding hypoglycaemia at baseline from a diabetes specialist nurse. They will wear a freestyle libre device which is changed every two weeks for a period of 6 months. At weeks 2,4,12 and 24 they will have their diabetes medication adjusted by the diabetes specialist nurse/diabetes doctor according to their blood glucose profiles, analysed from the data generated by freestyle libre.

Group Type EXPERIMENTAL

Freestyle libre

Intervention Type DEVICE

A glucose sensor (flash) which measures interstitial blood glucose every 15 minutes or on demand.

Nurse led structured intervention - hypoglycaemia education and diabetes treatment modification modification

Intervention Type OTHER

An education programme surrounding avoidance of hypoglycaemia at baseline. Regular review (weeks 2, 4, 12 and 24) and adjustment of diabetes medications based on freestyle libre data.
