Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will receive 2 doses of IM betamethasone 11.4mg 24 hours apart by the nurse in charge. Each participant will have a Flash glucose monitoring and a continuous glucose monitoring device inserted on the day of admission, prior to IM betamethasone administration. The glucose monitoring devices will be inserted by the study team member. The FGM device will be inserted into the upper outer aspect of the arm, while the CGM device will be inserted on the lower abdomen. This will be in addition to hourly capillary glucose monitoring which is part of routine care, which commences after betamethasone administration.

On day 2 of admission, the participants will have hourly venous blood drawn for glucose and ketones levels. 4 hourly urine ketones will also be collected on this day. IV insulin infusion will be initiated during hospitalisation, as per standard protocol/ medical care, with the rates adjusted according to the hourly capillary blood glucose readings. The IV insulin infusion can be initiated from day 2 of admission or earlier if blood glucose levels are high prior to IM betamethasone administration. Participants will be monitored till day after the second dose of IM betamethasone or until delivery, depending on Obstetrics indication. Hourly blood draws/ urine tests for the study will only be for the 2nd day after steroid use. Participants are encouraged to contInue the use of FGM/ CGM devices while hospitalized and on discharge (or till delivery)- maximum wear of 6 days for CGM and 2 weeks for FGM.

The accuracy of interstitial glucose levels as monitored by the flash glucose monitoring and continuous glucose monitoring devices will be compared against venous glucose retrospectively.

Outcomes
Primary outcome [1] 305328 0
Assess the accuracy of interstitial fluid glucose measures (Flash glucose monitoring [FGM], continuous glucose monitoring [CGM]) against capillary blood glucose and venous blood glucose measurement. We will be comparing the mean absolute difference (MAD), mean absolute relative difference (MARD), median absolute difference (MedAD) and median absolute relative difference (MedARD) of FGM and CGM against venous blood glucose.
Timepoint [1] 305328 0
Hourly monitoring of venous blood glucose with comparison against the interstitial blood glucose levels for 9 hours, commencing 9 hours after IM betamethasone injection.

This will be composite primary outcome.
Primary outcome [2] 305329 0
Compare accuracy of capillary blood ketone levels against venous blood beta-hydroxy-butyrate by mean absolute difference, and evaluate if urine ketone assessment corresponds with blood ketone assessment.
Timepoint [2] 305329 0
4 hourly urine ketones and hourly venous beta-hydroxybutyrate measurement against capillary blood ketones for 9 hours.

This will be composite secondary outcome.
Secondary outcome [1] 346187 0
Evaluate degree of hyperglycaemia after IM betamethasone in women with diabetes mellitus. This will be done by evaluating the interstitial glucose levels documented on FGM/ CGM devices, and serial venous blood glucose levels.
Timepoint [1] 346187 0
CGM and FGM devices will be worn prior to IM betamethasone administration, up to the point of delivery or for as long as participants are keen to continue wearing the devices (up to 2 weeks for FGM device, and up to 6 days for CGM device).
Secondary outcome [2] 347085 0
Evaluate temporal onset of hyperglycemia after betamethasone administration.
Timepoint [2] 347085 0
CGM and FGM devices will be worn prior to IM betamethasone administration, up to the point of delivery or for as long as participants are keen to continue wearing the devices (up to 2 weeks for FGM device, and up to 6 days for CGM device).
