Quality improvement strategies for diabetes care: Effects on outcomes for adults living with diabetes.

BACKGROUND: There is a large body of evidence evaluating quality improvement (QI) programmes to improve care for adults living with diabetes. These programmes are often comprised of multiple QI strategies, which may be implemented in various combinations. Decision-makers planning to implement or evaluate a new QI programme, or both, need reliable evidence on the relative effectiveness of different QI strategies (individually and in combination) for different patient populations. OBJECTIVES: To update existing systematic reviews of diabetes QI programmes and apply novel meta-analytical techniques to estimate the effectiveness of QI strategies (individually and in combination) on diabetes quality of care. SEARCH METHODS: We searched databases (CENTRAL, MEDLINE, Embase and CINAHL) and trials registers (ClinicalTrials.gov and WHO ICTRP) to 4 June 2019. We conducted a top-up search to 23 September 2021; we screened these search results and 42 studies meeting our eligibility criteria are available in the awaiting classification section. SELECTION CRITERIA: We included randomised trials that assessed a QI programme to improve care in outpatient settings for people living with diabetes. QI programmes needed to evaluate at least one system- or provider-targeted QI strategy alone or in combination with a patient-targeted strategy. - System-targeted: case management (CM); team changes (TC); electronic patient registry (EPR); facilitated relay of clinical information (FR); continuous quality improvement (CQI). - Provider-targeted: audit and feedback (AF); clinician education (CE); clinician reminders (CR); financial incentives (FI). - Patient-targeted: patient education (PE); promotion of self-management (PSM); patient reminders (PR). Patient-targeted QI strategies needed to occur with a minimum of one provider or system-targeted strategy. DATA COLLECTION AND ANALYSIS: We dual-screened search results and abstracted data on study design, study population and QI strategies. We assessed the impact of the programmes on 13 measures of diabetes care, including: glycaemic control (e.g. mean glycated haemoglobin (HbA1c)); cardiovascular risk factor management (e.g. mean systolic blood pressure (SBP), low-density lipoprotein cholesterol (LDL-C), proportion of people living with diabetes that quit smoking or receiving cardiovascular medications); and screening/prevention of microvascular complications (e.g. proportion of patients receiving retinopathy or foot screening); and harms (e.g. proportion of patients experiencing adverse hypoglycaemia or hyperglycaemia). We modelled the association of each QI strategy with outcomes using a series of hierarchical multivariable meta-regression models in a Bayesian framework. The previous version of this review identified that different strategies were more or less effective depending on baseline levels of outcomes. To explore this further, we extended the main additive model for continuous outcomes (HbA1c, SBP and LDL-C) to include an interaction term between each strategy and average baseline risk for each study (baseline thresholds were based on a data-driven approach; we used the median of all baseline values reported in the trials). Based on model diagnostics, the baseline interaction models for HbA1c, SBP and LDL-C performed better than the main model and are therefore presented as the primary analyses for these outcomes. Based on the model results, we qualitatively ordered each QI strategy within three tiers (Top, Middle, Bottom) based on its magnitude of effect relative to the other QI strategies, where 'Top' indicates that the QI strategy was likely one of the most effective strategies for that specific outcome. Secondary analyses explored the sensitivity of results to choices in model specification and priors.  Additional information about the methods and results of the review are available as Appendices in an online repository. This review will be maintained as a living systematic review; we will update our syntheses as more data become available. MAIN RESULTS: We identified 553 trials (428 patient-randomised and 125 cluster-randomised trials), including a total of 412,161 participants. Of the included studies, 66% involved people living with type 2 diabetes only. Participants were 50% female and the median age of participants was 58.4 years. The mean duration of follow-up was 12.5 months. HbA1c was the commonest reported outcome; screening outcomes and outcomes related to cardiovascular medications, smoking and harms were reported infrequently. The most frequently evaluated QI strategies across all study arms were PE, PSM and CM, while the least frequently evaluated QI strategies included AF, FI and CQI. Our confidence in the evidence is limited due to a lack of information on how studies were conducted.  Four QI strategies (CM, TC, PE, PSM) were consistently identified as 'Top' across the majority of outcomes. All QI strategies were ranked as 'Top' for at least one key outcome. The majority of effects of individual QI strategies were modest, but when used in combination could result in meaningful population-level improvements across the majority of outcomes. The median number of QI strategies in multicomponent QI programmes was three.  Combinations of the three most effective QI strategies were estimated to lead to the below effects:  - PR + PSM + CE: decrease in HbA1c by 0.41% (credibility interval (CrI) -0.61 to -0.22) when baseline HbA1c < 8.3%; - CM + PE + EPR: decrease in HbA1c by 0.62% (CrI -0.84 to -0.39) when baseline HbA1c > 8.3%;  - PE + TC + PSM: reduction in SBP by 2.14 mmHg (CrI -3.80 to -0.52) when baseline SBP < 136 mmHg; - CM + TC + PSM: reduction in SBP by 4.39 mmHg (CrI -6.20 to -2.56) when baseline SBP > 136 mmHg;  - TC + PE + CM: LDL-C lowering of 5.73 mg/dL (CrI -7.93 to -3.61) when baseline LDL < 107 mg/dL; - TC + CM + CR: LDL-C lowering by 5.52 mg/dL (CrI -9.24 to -1.89) when baseline LDL > 107 mg/dL. Assuming a baseline screening rate of 50%, the three most effective QI strategies were estimated to lead to an absolute improvement of 33% in retinopathy screening (PE + PR + TC) and 38% absolute increase in foot screening (PE + TC + Other). AUTHORS' CONCLUSIONS: There is a significant body of evidence about QI programmes to improve the management of diabetes. Multicomponent QI programmes for diabetes care (comprised of effective QI strategies) may achieve meaningful population-level improvements across the majority of outcomes. For health system decision-makers, the evidence summarised in this review can be used to identify strategies to include in QI programmes. For researchers, this synthesis identifies higher-priority QI strategies to examine in further research regarding how to optimise their evaluation and effects. We will maintain this as a living systematic review.

Probiotics and non-alcoholic fatty liver disease in children and adolescents: a systematic review.

BACKGROUND: non-alcoholic fatty liver disease (NAFLD) in childhood is an increasing global public health issue with significant long-term consequences. NAFLD management mainly consists of lifestyle modifications, however, adjunct pharmacological therapies are currently lacking. Gut microbiota manipulation via probiotics may alter the course of pediatric NAFLD. The objective of this systematic review was to synthesize all the available literature on the use of probiotics in children and adolescents with NAFLD. METHODS: PubMed, EBSCOhost, Scopus, Web of Science, and Cochrane Library were systematically searched for trials on the use of probiotics in pediatric NAFLD. A quantitative DerSimonian Laird random effects meta-analysis was performed when possible; otherwise, a narrative summary of the study outcomes was presented and discussed. A separate search was completed to include all the ongoing registered trials on probiotics use in pediatric NAFLD. RESULTS: five randomized controlled trials met the inclusion criteria. Of these, four trials were included in the final quantitative analysis. Probiotic therapy significantly reduced the levels of alanine aminotransferase (ALT) (mean difference: -10.39 [-19.85, -0.93]), however significant heterogeneity between studies was identified (I2, 93 %). CONCLUSIONS: there is insufficient evidence to support probiotics in the treatment of pediatric NAFLD given the substantial degree of discordance amongst the available trials. Lifestyle modifications focusing on maintaining a normal BMI and regular exercise continue to be the gold standard approach to treating NAFLD in children.

Emergency department attendances during the COVID-19 pandemic: a retrospective analysis of attendances following Irish governmental pandemic measures.

BACKGROUND: COVID-19 has resulted in the death of over 1 million people to date. Following government-implemented regulations, there has been concern over the apparent decline in emergency department (ED) attendances and the resultant health legacy. Therefore, we aimed to characterise the attendances to an Irish tertiary hospital ED following the implementation of these regulations during the COVID-19 pandemic. METHODS: This retrospective observational study investigated all attendances to the Cork University Hospital ED from 15 February to 11 April in 2020 and 2017-2019. Attendances were stratified into four periods: Before COVID (BC) (15 February to 5 March), After COVID (AC) (6 March to 12 March), Educational Closure (EC) (13 March to 27 March) and Stay Home (SH) (28 March to 11 April), as per government regulations. Triage presentations of abdominal pain, shortness of breath, chest pain, headache and trauma were examined. Data were analysed by independent t-tests and χ2 analysis. RESULTS: There were 8261 attendances to the ED in the 2020 time period compared with a mean of 10 389 attendances during the corresponding periods in 2017-2019. There was a significant decrease in daily attendances in 2020 compared with 2017-2019 in the AC (142 vs 188, p=0.02), EC (122 vs 184, p<0.001) and SH (121 vs 181, p<0.001) periods, including significant decreases in abdominal pain (AC: 9 vs 22, EC: 10 vs 19, SH: 11 vs 18, p<0.001), chest pain (AC: 9 vs 15, EC: 8 vs 15, SH: 9 vs 15, p<0.01), headache (AC: 5 vs 11, EC: 4 vs 9, SH: 4 vs 9, p<0.01) and trauma (AC: 3 vs 5, EC: 2 vs 6, SH: 3 vs 5, p<0.01). CONCLUSION: Our findings suggest that the combination of government-imposed restrictions and perceived risk of attending an ED during a pandemic may contribute to reduced attendances. Public confidence in EDs is necessary to reduce collateral damage caused by failure to seek medical attention during a pandemic; adequate infrastructure to allow social distancing and isolation capacity in EDs is a necessity.

Management of COVID-19-associated multisystem inflammatory syndrome in children: A comprehensive literature review.

BACKGROUND: The prevalence and severity of COVID-19 are greatly reduced in children, yet some pediatric patients develop a syndrome resembling Kawasaki Disease (KD), termed Multisystem Inflammatory Syndrome in Children (MIS-C). With an estimated incidence of 2/100,000 children, MIS-C is relatively rare but can be fatal. Clinical features can include fever, hyperinflammatory state, gastrointestinal symptoms, myocardial dysfunction, and shock. The pathogenesis of MIS-C, although yet to be completely elucidated, appears to be distinct from KD in terms of epidemiology, severity, and biochemical signature. AIM OF REVIEW: Although efficacy of treatments for MIS-C have largely not yet been investigated, we aim to conduct a comprehensive literature search of numerous medical databases (AMED, EBM Reviews, Embase, Healthstar, MEDLINE, ERIC, and Cochrane) to highlight treatments used around the world, their rationale, and outcomes to better inform guidelines in the future. Using the findings, an approach to MIS-C management will be outlined. KEY SCIENTIFIC CONCEPTS OF REVIEW: •MIS-C appears to be a SARS-CoV-2 related post-infection phenomenon that is distinct from Kawasaki disease.•Although outcomes are largely favorable, there is significant variation in MIS-C treatment. Most management regimens reported to date mirror that of KD; however, targeted therapy based on specific MIS-C phenotypes may have the potential to improve outcomes.•We recommend close monitoring by a multidisciplinary team, symptomatic treatment (e.g., intravenous immunoglobulin for KD-like symptoms, steroids/immunotherapy for multisystem inflammation), and long-term follow-up.•Further research is required to evaluate the effectiveness of current MIS-C treatments and to determine more refined therapies.

Inside the skin of a patient with diabetes: fostering cognitive empathy through insulin pump simulation.

In order to best treat a patient, the carer must be able to clearly see their point of view. In the case of the complexities of insulin pump therapy, physicians may not fully understand the common challenges that drive patients to non-adherence. The author undertook a three-day simulation using wearable technology to explore this experience. This form of simulation represents a simple yet effective means by which to foster cognitive empathy in undergraduate and postgraduate medical education settings alike.

Pour offrir le meilleur traitement possible, le soignant doit être en mesure de voir les choses du point de vue du patient. Or, les médecins pourraient ne pas comprendre les défis courants liés à la complexité du traitement par pompe à insuline qui expliquent la non-observance thérapeutique chez les patients. L'auteur a mené une simulation de trois jours pour explorer l'expérience de ce traitement à l'aide d'une technologie portable. Cette forme de simulation constitue un moyen simple et efficace pour favoriser l'empathie cognitive dans les établissements d'enseignement médical prédoctoral et postdoctoral.

Is Adipose Tissue a Reservoir for Viral Spread, Immune Activation, and Cytokine Amplification in Coronavirus Disease 2019?

Coronavirus disease 2019 (COVID-19), the worst pandemic in more than a century, has claimed >125,000 lives worldwide to date. Emerging predictors for poor outcomes include advanced age, male sex, preexisting cardiovascular disease, and risk factors including hypertension, diabetes, and, more recently, obesity. This article posits new obesity-driven predictors of poor COVID-19 outcomes, over and above the more obvious extant risks associated with obesity, including cardiometabolic disease and hypoventilation syndrome in intensive care patients. This article also outlines a theoretical mechanistic framework whereby adipose tissue in individuals with obesity may act as a reservoir for more extensive viral spread, with increased shedding, immune activation, and cytokine amplification. This paper proposes studies to test this reservoir concept with a focus on specific cytokine pathways that might be amplified in individuals with obesity and COVID-19. Finally, this paper underscores emerging therapeutic strategies that might benefit subsets of patients in which cytokine amplification is excessive and potentially fatal.

Lessons from across the pond: Student perspectives on the Internal Medicine clerkship experience at an Irish and Canadian medical school.

This article was migrated. The article was marked as recommended. There is an increasing number of Canadians studying medicine outside of Canada, with a large cohort studying in Ireland. Studying abroad often means different foci in medical training which may make transitioning to residency in a different system more challenging. Students often enter North American elective rotations with little knowledge of student roles and responsibilities. This paper provides insight into the differences in learning objectives and student experiences in an Internal Medicine clerkship at a medical school in Canada and Ireland. Learning objectives are similar between systems; but there is an experiential discordance. In Ireland, clerks see many different patients, gaining exposure to a breadth of topics and clinical signs, but medical student presentations rarely inform decisions around patient care. In Canada, clerks have more direct patient responsibilities, performing physical examinations, reviewing investigations, writing progress notes, and devising management plans as part of their professional development. Overall, the Irish system places emphasis on the mastery of core clinical skills and maximizing breadth of patient exposure whereas the Canadian clerkship is more focused on graduated responsibility and formulating management plans, at the expense of some breadth of exposure. Such discrepancies may not affect the quality of residents, but are important considerations for Canadians studying abroad when repatriating for electives and residencies.

Small Intestinal Bacterial Overgrowth in Children: A State-Of-The-Art Review.

Small intestinal bacterial overgrowth (SIBO) is a heterogenous and poorly understood entity characterised by an excessive growth of select microorganisms within the small intestine. This excessive bacterial biomass, in turn, disrupts host physiology in a myriad of ways, leading to gastrointestinal and non-gastrointestinal symptoms and complications. SIBO is a common cause of non-specific gastrointestinal symptoms in children, such as chronic abdominal pain, abdominal distention, diarrhoea, and flatulence, amongst others. In addition, it has recently been implicated in the pathophysiology of stunting, a disease that affects millions of children worldwide. Risk factors such as acid-suppressive therapies, alterations in gastrointestinal motility and anatomy, as well as impoverished conditions, have been shown to predispose children to SIBO. SIBO can be diagnosed via culture-dependant or culture-independent approaches. SIBO's epidemiology is limited due to the lack of uniformity and consensus of its diagnostic criteria, as well as the paucity of literature available. Antibiotics remain the first-line treatment option for SIBO, although emerging modalities such as probiotics and diet manipulation could also have a role. Herein, we present a state-of-the-art-review which aims to comprehensively outline the most current information on SIBO in children, with particular emphasis on the gut microbiota.

Paediatrician's perspective of infant gut microbiome research: current status and challenges.

Due to its innately intriguing nature and recent genomic technological advances, gut microbiome research has been at the epicentre of medical research for over a decade now. Despite the degree of publicisation, a comprehensive understanding and, therefore, acceptance of the area as a whole may be somewhat lacking within the broader medical community. This paper summarises the main analytical techniques and tools currently applied to compositional microbiome research. In addition, we outline five major lessons learnt from a decade of infant microbiome research, along with the current research gaps. Finally, we aim to provide an introduction and general guidelines relating to infant gut microbiome research for the practising paediatrician.
