‘Sink or Swim’: A Qualitative Study to Understand How and Why Nurses Adapt to Support the Implementation of Integrated Diabetes Care

Background: Integrated care, organising care delivery within and between services, is an approach to improve the quality of care. Existing specialist roles have evolved to work across settings and services to integrate care. However, there is limited insight into how these expanded roles are implemented, including how they may be shaped by context. This paper examines how new diabetes nurse specialists working across care boundaries, together with hospital-based diabetes nurse specialists, adapt to support the implementation of integrated care. Methods: We conducted semi-structured focus groups and interviews with diabetes nurse specialists purposively sampled by work setting and health service region (n = 30). Analysis was data-driven, coding actions or processes to stay closer to the data and using 'In Vivo' codes to preserve meaning. Findings: Community nurse specialists described facing a choice of “sink or swim” when appointed with limited guidance on their role. To ‘swim’ and implement their role, required them to use their initiative and adapt to the local context. When first appointed, both community and hospital nurse specialists actively managed misconceptions of their role by other staff. To establish clinics in general practices, community nurse specialists capitalised on professional contacts to access GPs who might utilise their role. They built GP trust by adopting practice norms and responding to individual needs. They adapted to the lack of a multidisciplinary team “safety net” in the community, by “practicing at a higher level”, working more autonomously. Developing professional links and pursuing on-going education was a way to create an alternative ‘safety net’ so as to feel confident in their clinical decision-making when working in the community. Workarounds facilitated information flow (i.e. patient blood results, treatment, and appointments) between settings in the absence of an electronic record shared between general practices and hospital settings. Conclusions: Flexibility and innovation facilitates a new way of working across boundaries. Successful implementation of nurse specialist-led integrated care requires strategies to address elements in the inner (differences in practice organisation, role acceptance) and outer (information systems) context

A core outcomes set for clinical trials of interventions for young adults with type 1 diabetes: an international, multi-perspective Delphi consensus study

BACKGROUND: Achieving consensus from a range of relevant stakeholders about an agreed set of core outcomes to be measured and reported as a minimum in clinical trials has the potential to enhance evidence synthesis and make findings more relevant and applicable. Intervention research to improve outcomes for young adults with type 1 diabetes (T1DM) is hampered by inconsistent use of outcome measures. This population frequently struggles to manage their condition and reports suboptimal clinical outcomes. Our aim was to conduct an international, e-Delphi consensus study to identify a core outcome set (COS) that key stakeholders (young adults with T1DM, diabetes health professionals, diabetes researchers and diabetes policy makers) consider as essential outcomes for future intervention research. METHODS: Using a list of 87 outcomes generated from a published systematic review, we administered two online surveys to a sample of international key stakeholders. Participants in the first survey (survey 1; n = 132) and the second survey (survey 2; n = 81) rated the importance of the outcomes. Survey 2 participants received information on total mean rating for each outcome and a reminder of their personal outcome ratings from Survey 1. Survey 2 results were discussed at a consensus meeting and participants (n = 12: three young adults with T1DM, four diabetes health professionals, four diabetes researchers and one diabetes policy maker) voted on outcomes. Final core outcomes were included provided that 70% of consensus group participants voted for their inclusion. RESULTS: Eight core outcomes were agreed for inclusion in the final COS: measures of diabetes-related stress; diabetes-related quality of life; number of severe hypoglycaemic events; self-management behaviour; number of instances of diabetic ketoacidosis (DKA); objectively measured glycated haemoglobin (HbA1C); level of clinic engagement; and perceived level of control over diabetes. CONCLUSIONS: This study is the first to identify a COS for inclusion in future intervention trials to improve outcomes for young adults with T1DM. Use of this COS will improve the quality of future research and increase opportunities for evidence synthesis. Future research is necessary to identify the most robust outcome measure instruments

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

Optical extinction of size-controlled aerosols generated from squid chromatophore pigments

Nanophotonic granules populate the interior of cephalopod chromatophores, contributing to their visible color by selectively absorbing and scattering light. Inspired by the performance of these granules, we fabricated nanostructured aerosols by nebulizing a pigment solution extracted from native squid chromatophores. We determined their optical extinction using cavity ring-down spectroscopy and show how extinction cross section is dependent on both particle concentration and size. This work not only advances the fundamental knowledge of the optical properties of chromatophore pigments but also serves as a proof-of-concept method that can be adapted to develop coatings derived from these pigmentary aerosols

Delivering value‐based healthcare for people with diabetes in a national publicly funded health service: Lessons from Ireland and Wales

Abstract The term value‐based healthcare (VBHC) describes an approach to the organization and delivery of care that emphasizes reducing the cost of care while improving outcomes. This involves increased investment earlier in the care pathway e.g., in the prevention, timely diagnosis, and screening for complications in order to maximize the overall impact of care. Key elements of VBHC include the collection and interpretation of relevant data to drive quality improvement and appropriateness of care, a focus on a continuum of care from prevention through to complications, an awareness of the financial drivers of the cost of care and a recognition that meaningful outcomes of care are those that are important to patients. Although VBHC has its origins in North America and has mostly been applied to private health systems, the principles can also be applied to national health services. In publicly funded health systems, where resources are finite, VBHC initiatives aim to eliminate ineffective care that has no beneficial impact or added value for patients and to optimize patient outcomes by delivering care that meets the changing healthcare needs of a population over time. The National Health Service in Wales has established a VBHC Office and has begun to realize the benefits of adopting VBHC approaches. The Irish Health Service Executive (HSE) can learn from the approaches used in Wales. In this paper we explore some of the principles of VBHC through case studies from Ireland and Wales highlighting how national health services are using VBHC to achieve improvement in outcomes for people living with diabetes

Cost effectiveness of group follow-up after structured education for type 1 diabetes: a cluster randomised controlled trial

Background: This study examines the cost effectiveness of group follow-up after participation in the Dose Adjustment for Normal Eating (DAFNE) structured education programme for type 1 diabetes. Methods: Economic evaluation conducted alongside a cluster randomised controlled trial involving 437 adults with type 1 diabetes in Ireland. Group follow-up involved two group education \u27booster\u27 sessions post-DAFNE. Individual follow-up involved two standard one-to-one hospital clinic visits. Incremental costs, quality-adjusted life years (QALYs) gained and cost effectiveness were estimated at 18 months. Uncertainty was explored using sensitivity analysis and by estimating cost effectiveness acceptability curves. Results: Group follow-up was associated with a mean reduction in QALYs gained of 0.04 per patient (P value, 0.052; 95% CI, -0.08 to 0.01, intra-class correlation (ICC), 0.033) and a mean reduction in total healthcare costs of is an element of 772 (P value, 0.020; 95% CI, -1,415 to -128: ICC, 0.016) per patient. At alternative threshold values of is an element of 5,000, is an element of 15,000, is an element of 25,000, is an element of 35,000, and is an element of 45,000, the probability of group follow-up being cost effective was estimated to be 1.000, 0.762, 0.204, 0.078, and 0.033 respectively. Conclusions: The results do not support implementation of group follow-up as the sole means of follow-up post-DAFNE. Given the reported cost savings, future studies should explore the cost effectiveness of alternative models of group care for diabetes

Risperidone-induced type 2 diabetes presenting with diabetic ketoacidosis

A 28-year-old male presented with 2 days of vomiting and abdominal pain, preceded by 2 weeks of thirst, polyuria and polydipsia. He had recently started risperidone for obsessive-compulsive disorder. He reported a high dietary sugar intake and had a strong family history of type 2 diabetes mellitus (T2DM). On admission, he was tachycardic, tachypnoeic and drowsy with a Glasgow Coma Scale (GCS) of 10/15. We noted axillary acanthosis nigricans and obesity (BMI 33.2 kg/m(2)). Dipstick urinalysis showed ketonuria and glycosuria. Blood results were consistent with diabetic ketoacidosis (DKA), with hyperosmolar state. We initiated our DKA protocol, with intravenous insulin, fluids and potassium, and we discontinued risperidone. His obesity, family history of T2DM, acanthosis nigricans and hyperosmolar state prompted consideration of T2DM presenting with 'ketosis-prone diabetes' (KPD) rather than T1DM. Antibody markers of beta-cell autoimmunity were subsequently negative. Four weeks later, he had modified his diet and lost weight, and his metabolic parameters had normalised. We reduced his total daily insulin dose from 35 to 18 units and introduced metformin. We stopped insulin completely by week 7. At 6 months, his glucometer readings and glycated haemoglobin (HbA1c) level had normalised
