Health systems invest in diabetes quality improvement (QI) programmes to reduce the gap between research evidence of optimal care and current care.1 Examples of commonly used QI strategies in diabetes include programmes to measure and report quality of care (ie, audit and feedback initiatives), implementation of clinician and patient education, and reminder systems. A recent systematic review of randomised trials of QI programmes indicates that they can successfully improve quality of diabetes care and patient outcomes.2 Changes in surrogate markers such as blood glucose control, blood pressure or cholesterol levels are used to measure QI intervention effectiveness.2
However, investments in QI strategies are only worthwhile if the programmes that effectively improve care are sustained after trial completion.3 Failure to maintain QI programmes contributes to substantial research waste, resulting in suboptimal patient care since the effective interventions are not available.4 5 Furthermore, failure to redirect resources from ineffective programmes creates opportunity cost. To date, no studies have examined the sustainability of rigorously evaluated diabetes QI programmes. The objective of this study is to explore factors associated with sustained implementation of diabetes QI programmes after cessation of their research funding.
In 2018, we emailed the authors of 226 trials on diabetes QI programmes and requested them to complete an online survey about their perceived sustainability of their intervention. These trials were published between 2004 and …
