Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
A proactive inpatient diabetes service (IDS)

1) Consists of an endocrinology registrar & diabetes nurse practitioner, overseen by an endocrinologist. The IDS will also include diabetes nurse educators and a dietician.

2) Identifies inpatients with known diabetes or new hyperglycaemia without diabetes (fasting BGL > 7.0 mmol/L or random BGL > 11.1 mmol/L) using Connectivity Blood Glucose Meters (CBGM) and a central repository of point of care blood glucose levels (BGL).

3) Identifies inpatients with unstable BGL or altered clinical state via the Glucose Alert Pathway. Glucose alert pathway is a paper-based clinical escalation guideline for nursing and treating team medical staff in response to hypoglycaemia, hyperglycaemia or a change in diabetes-related clinical status.

4) Delivers a consult service on all patients with known diabetes or new hyperglycaemia, early in their admission (aim within 48 hours after admission) & without referral from the treating team (proactive care). The consultation includes:
a) Assessment of diabetes control prior to admission and during hospitalisation.
b) Appropriate adjustment of diabetes-related medications and insulin during hospitalisation
c) Provision of appropriate diabetes education and/or dietary advice
d) Optimisation of diabetes therapy at discharge from hospital
A typical consult may last 5 - 20 minutes depending on the clinical scenario. The IDS may provide a single or multiple consults depending on clinical status. (e.g. if regular insulin or diabetes medication dose titration is required, there may be daily or second-daily consults, until discharge).

5) Delivers individualised diabetes care in hospital using a variety of appropriate diabetes medication and insulin regimens depending on the clinical scenario.

6) Facilitate discharge by formulating diabetes regimen and follow up plans following discharge. These plans will be communicated to the patient's local medical officer by a discharge summary.

The IDS intervention will be in place for 3 months.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Cluster randomised design, based on participating wards.
8 participating wards are included (4 medical and 4 surgical).
The wards will be randomised to 4 control and 4 intervention arms in a stratified manner so that even number of surgical and medical wards will be in each arm.

A random list of randomisation codes will be generated by a statistician and paired against a random medical or surgical ward in a stratified manner.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Masking / blinding
Open (masking not used)

Intervention assignment
Other
Other design features
In an initial 3-months baseline period, patient and glycaemic outcomes will be recorded from all 8 participating wards.
Following this, the wards will be cluster randomised into 4 intervention and 4 control wards.
A 3-month intervention period will then follow, where the 4 intervention wards will receive proactive IDS, and 4 control wards will continue usual care.

The initial 3 month baseline period will help evaluate the effect of intervention as a change from baseline for each ward.
Phase
Not Applicable
Type of endpoint/s
Efficacy
Statistical methods / analysis
Baseline adverse glycaemic days (from pilot study) = 30%
Expected recruitment during baseline phase = 600 (8 wards)
Expected recruitment during intervention phase = 600 (8 wards) or 300 patients in each arm (4 wards) totalling 1050 patient-days.
Using inter-cluster correlation coefficient of 0.05, and alpha of 0.05, there is > 80% power to detect a change of adverse glycaemic days from 30% to 20%.
