RESUMO
BACKGROUND: People with type 1 diabetes and raised glucose levels are at greater risk of retinopathy, nephropathy, neuropathy, cardiovascular disease, sexual health problems and foot disease. The UK National Institute for Health and Care Excellence (NICE) recommends continuous subcutaneous 'insulin pump' therapy for people with type 1 diabetes whose HbA1c is above 69 mmol/mol. Insulin pump use can improve quality of life, cut cardiovascular risk and increase treatment satisfaction. About 90,000 people in England and Wales meet NICE criteria for insulin pumps but do not use one. Insulin pump use also varies markedly by deprivation, ethnicity, sex and location. Increasing insulin pump use is a key improvement priority. Audit and feedback is a common but variably effective intervention. Limited capabilities of healthcare providers to mount effective responses to feedback from national audits, such as the National Diabetes Audit (NDA), undermines efforts to improve care. We have co-developed a theoretically and empirically informed quality improvement collaborative (QIC) to strengthen local responses to feedback with patients and carers, national audits and healthcare providers. We will evaluate whether the QIC improves the uptake of insulin pumps following NDA feedback. METHODS: We will undertake an efficient cluster randomised trial using routine data. The QIC will be delivered alongside the NDA to specialist diabetes teams in England and Wales. Our primary outcome will be the proportion of people with type 1 diabetes and an HbA1c above 69 mmol/mol who start and continue insulin pump use during the 18-month intervention period. Secondary outcomes will assess change in glucose control and duration of pump use. Subgroup analyses will explore impacts upon inequalities by ethnicity, sex, age and deprivation. A theory-informed process evaluation will explore diabetes specialist teams' engagement, implementation, fidelity and tailoring through observations, interviews, surveys and documentary analysis. An economic evaluation will micro-cost the QIC, estimate cost-effectiveness of NDA feedback with QIC and estimate the budget impact of NHS-wide QIC roll out. DISCUSSION: Our study responds to a need for more head-to-head trials of different ways of reinforcing feedback delivery. Our findings will have implications for other large-scale audit and feedback programmes. TRIAL REGISTRATION: ISRCTN82176651 Registered 18 October 2022.

BACKGROUND: National audits are a common, but variably effective, intervention to improve services. This study aimed to design an intervention to increase the effectiveness of national audit. METHODS: We used interviews, documentary analysis, observations, co-design and stakeholder engagement methods. The intervention was described in an intervention manual and illustrated using a logic model. Phase 1 described the current hospital response to a national audit. Phase 2 identified potential enhancements. Phase 3 developed a strategy to implement the enhancements. Phase 4 explored the feasibility of the intervention alongside the National Audit of Dementia and refined the intervention. Phase 5 adapted the intervention to a second national audit (National Diabetes Audit). Phase 6 explored the feasibility and fidelity of the intervention alongside the National Diabetes Audit and used the findings to further refine the intervention. RESULTS: The developed intervention is a quality improvement collaborative (QIC), containing virtual educational workshop, virtual outreach for local team leads and virtual facilitation of a learning collaborative delivered after feedback has been received. The QIC aims to support national audit recipients to undertake improvement actions tailored to their local context. The target audience is clinical and clinical governance leaders. We found that actions from national audit were constrained by what the clinical lead perceived they deliver personally, these actions were not aligned to identified influences upon performance. We found that the hospital response could be enhanced by targeting low baseline performance, identifying and addressing influences upon to performance, developing trust and credibility, addressing recipient priorities, presenting meaningful comparisons, developing a conceptual model, involving stakeholders and considering the opportunity cost. Phase 3 found that an educational workshop and outreach strategy could support implementation of the enhancements through developing coherence and cognitive participation. We found feasibility could be increased by revising the content, re-naming the intervention, amending activities to address time commitment, incorporating a more structured analysis of influences, supporting collaboration and developing local feedback mechanisms. Phase 5 found adaptation to a second national audit involved reflecting differences in the clinical topic, context and contractual requirements. We found that the behaviour change techniques identified in the manual were delivered by facilitators. Participants reported positive attitudes towards the intervention and that the intervention was appropriate. CONCLUSIONS: The QIC supports local teams to tailor their actions to local context and develop change commitment. Future work will evaluate the effectiveness of the intervention as an adjunct to the National Diabetes Audit.
