Plain English Summary
Background and study aims
Diabetes is a life-long condition where a person is unable to control their blood sugar levels. There are type main types of diabetes. In type 1 diabetes the body is unable to produce a hormone called insulin, which is responsible for breaking down glucose and turning it into energy. In type 2 diabetes the body either does not produce enough insulin to function properly (insulin deficiency), or that the body’s cells don’t react to insulin as they should do (insulin resistance). Diabetes is one of the main causes of kidney failure, as the fluxuations in blood sugar that characterise diabetes can cause damage to the kidneys (nephropathy), which can lead to kidney failure. When the kidneys fail, they stop cleaning the blood, leading to the build-up of harmful waste products. Haemodialysis is one of the most common treatments for kidney failure. It involves diverting the blood into an external machine so that it can be cleaned, before being returned to the body. Having to manage treatment for diabetes and kidney failure can be very difficult to patients. The aim of this study is to evaluate a new nurse-led self-management program designed to empower diabetes patients on dialysis, to help them better manage their condition.
Who can participate?
Patients aged 21 and over with diabetes and kidney failure, who have been receiving haemodialysis treatment.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive standard treatment for the duration of the study. Those in the second group take part in the nurse-led self-management program. This involves attending three 30 minute sessions with NKF diabetes link nurses during normal dialysis sessions at the dialysis centre. In these sessions, the nurse support patients in setting healthy goals and provide education around diet, medication, exercise, foot care or blood sugar monitoring. The content is tailored to patients’ needs and preferences for support. At the start of the study and then again 2-4 weeks after the end of the self-management program, participants in both groups complete a number of questionnaires about how they deal with their illness, treatment recommendations, and emotional wellbeing. Information about how well participants are controlling their diabetes and their kidney health is taken from medical records at the same times. At the end of the study, participants are also interviewed about their experiences of the program.
What are the possible benefits and risks of participating?
Participants may benefit from learning how to better manage their condition, which could improve their mental and physical health. There are no notable risks involved with participating in this study.
Where is the study run from?
Five dialysis centres in Singapore (Singapore)
When is the study starting and how long is it expected to run for?

Scientific title
Improving outcomes in patients with coexisting multi-morbid conditions – the development and evaluation of the combined diabetes and renal control feasibility trial (C-DIRECT)
Acronym
C-DIRECT
Study hypothesis
Overall study aim:
The aim of this study is to assess the feasibility and acceptability of a nurse-led intervention based on motivational interviewing (MI) and self management and its potential efficacy to improve glycaemic control, as well as psychosocial and self-care outcomes of patients with coexisting End stage renal disease and diabetes mellitus (DM-ESRD) compared with usual care.
Study aims:
1. To explore rates of recruitment and retention into the trial
2. To examine willingness to be randomised to either the intervention arm standard care
3. To explore the potential efficacy of C-DIRECT intervention when compared to usual care in improve glycaemic control and other clinical markers (interdialytic weight gains, blood pressure, serum potassium and phosphate levels and nutritional markers)
4. To compare quality of life, psychosocial and self-care outcomes between the intervention arm and control arm
5. To qualitatively explore patient and facilitators’ experience of the program, and identify areas of improvement for (any) further refinements

Condition
Coexisting Diabetes Mellitus and End Stage Renal Disease
Intervention
Participants are randomised to one of two groups in a 1:1 allocation ratio.
Intervention group: Participants will take part in a brief nurse led program designed to support adjustments to the lifestyle changes required by diabetes patients on hemodialysis. This will involve 3 visits by the NKF diabetes link nurses during one of their regular dialysis sessions at the dialysis center. During these sessions, the nurses will support patients in setting goals and will provide education around diet, medication, exercise, foot care or blood sugar monitoring, if they so require (based on Elicit-Provide-Elicit framework in Motivational Interviewing). The contents of the sessions will be tailored to their needs and preferences for support. Participants will decide the direction and content of these empowering conversations. A self-management record sheet will be used as part of the consultation. DM Link renal nurses and patients work together to complete the sheet in each session. Focus of each session, goal setting and confidence will be recorded. These visits will take approximately 30 minutes and will be scheduled over 3 consecutive weeks.
Control group: Participants will receive standard care for the duration of the study.
Assessment procedures are identical for control and intervention participants . These include a baseline assessment (self report questionnaires listed) and follow up assessment (12 weeks post baseline) - this is approximately 2-4 weeks post completion of the C-DIRECT intervention. Follow up assessments include same set of questionnaires (C-DRECT participants will also be invited to participate in a brief interview on their experience of the program).
