Site-specific factors associated with clinical trial recruitment efficiency in general practice settings: a comparative descriptive analysis.

Background: Recruitment of participants is crucial to the success of randomised control trials (RCTs) but can be challenging and expensive. Current research on trial efficiency is often focused at the patient-level with an emphasis on effective recruitment strategies. Less is known about selection of study sites to optimise recruitment.

Impact of quarterly professional-mode flash glucose monitoring in adults with type 2 diabetes in general practice (GP-OSMOTIC): Secondary psychological and self-care outcomes of a pragmatic, open-label, 12-month, randomised controlled trial.

Aims: To investigate the impact of quarterly professional-mode flash glucose monitoring on psychological outcomes in adults with type 2 diabetes in primary care.

Methods: The GP-OSMOTIC trial randomised 299 adults with type 2 diabetes in 25 general practices to quarterly use of professional-mode flash glucose monitoring (sensor worn for 14 days; data discussed at clinic visit) or usual care. At baseline and 12 months, participants completed validated measures: general emotional well-being (WHO-5), diabetes-specific quality of life (DIDP), satisfaction with glucose monitoring (GME-Q), self-care activities (SDSCA) and perceived involvement in clinical care (PICS).

Use of professional-mode flash glucose monitoring, at 3-month intervals, in adults with type 2 diabetes in general practice (GP-OSMOTIC): a pragmatic, open-label, 12-month, randomised controlled trial.

Background: Continuous glucose monitoring, either real-time (personal) or retrospective (professional mode), can identify day-to-day glucose profiles to guide management decisions for people with type 2 diabetes. We aimed to examine the effects of professional-mode flash glucose monitoring, done at 3-month intervals, in adults with type 2 diabetes in general practice.

Methods: We did a pragmatic, two-arm, open label, 12-month, individually randomised controlled trial (GP-OSMOTIC) in 25 general practices in Victoria, Australia.

GP-OSMOTIC trial protocol: an individually randomised controlled trial to determine the effect of retrospective continuous glucose monitoring (r-CGM) on HbA1c in adults with type 2 diabetes in general practice.

Introduction: Optimal glycaemia can reduce type 2 diabetes (T2D) complications. Observing retrospective continuous glucose monitoring (r-CGM) patterns may prompt therapeutic changes but evidence for r-CGM use in T2D is limited. We describe the protocol for a randomised controlled trial (RCT) examining intermittent r-CGM use (up to 14 days every three months) in T2D in general practice (GP).
