Abstract
OBJECTIVE To analyse the mechanisms at play in the adjudications made by professionals and socially vulnerable patients with type 2 diabetes about their eligibility for care. DESIGN, SETTING AND SUBJECTS The study included 14 patients and 10 health professionals in seven general practice surgeries in deprived areas in Greater Copenhagen. The study data consist of 17 semi-structured interviews with patients and 22 with health professionals immediately after observation of 23 consultations. Our analytical approach was inspired by Systematic Text Condensation and the concept of 'candidacy' for access to health care. RESULTS Adjudications of patients not being candidates for services were common, but we also found that both patients and health professionals worked to align the services to the needs of the patients. This could include using services differently than was intended by the providers or by changing routines to make it easier for patients to use the services. We discuss these processes as 'tinkering'. This usually implies that the best individual solution for the patient is aimed for, and in this study, the best solution sometimes meant not focusing on diabetes. CONCLUSION The study adds to existing knowledge about access to services for socially vulnerable patients by demonstrating that both patients and professionals in general practice engage in tinkering processes to make services work.

Abstract
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.

Association of renal function screening frequency with renal function decline in patients with type 2 diabetes: a real-world study in primary health care. BMC Nephrol 2022; 23:356. [PMCID: PMC9636837 DOI: 10.1186/s12882-022-02979-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2022] [Accepted: 10/20/2022] [Indexed: 11/06/2022] Open
Abstract
Abstract
Aims
To examine the association of the screening frequency of estimated glomerular filtration rate (eGFR) with the substantial reduction in eGFR (≥ 25%) among type 2 diabetes (T2D) patients with normal (eGFR≥60 ml/min/1.73 m2) and impaired kidney function (eGFR< 60 ml/min/1.73 m2).
Methods
A longitudinal study involving 5104 T2D patients with follow-up period of 6.8 years (1.9 SD) were treated at the Rovaniemi Health Center, Rovaniemi, Finland during 2011–2019. The association between the screening frequency of eGFR (yearly vs. non-yearly) and the substantial reduction in eGFR was studied with logistical models and adjusted with biochemical variables and preventive medications.
Results
Among the T2D patients with normal kidney function, non-yearly eGFR screening was significantly associated with substantial eGFR reduction in both unadjusted (odds ratio [OR] 3.29, 95% confidence interval [CI] 2.54–4.33) and adjusted models (OR 2.06, 95% CI 1.21–3.73) compared with yearly screening frequency. In the group of patients with impaired kidney function in the unadjusted model, non-yearly eGFR screening was significantly associated with substantial eGFR reduction (OR 2.38, 95% CI 1.30–4.73), but became non-significant after adjustments (OR 1.89, 95% CI 0.61–7.21).
Conclusions
This study underscores the role of regular eGFR screening in the prevention of kidney function decline.

Abstract
This narrative review describes a new approach to navigation in a challenging landscape of clinical drug development in diabetes. Successful outcome studies in recent years have led to new indications and guidelines in type 2 diabetes, yet the number of clinical trials in diabetes is now declining. This is due to many environmental factors acting in concert, including the prioritisation of funding for other diseases, high costs of large randomised clinical trials, increase in regulatory requirements and limited entry of novel candidate drugs. There is a need for novel and cost-effective paradigms of clinical development to meet these and other challenges. The concept of registry-based randomised clinical trials (RRCTs) is an attractive option. In this review we focus on type 2 diabetes and the prevention of cardiovascular and microvascular comorbidities and mortality, using the Swedish SMARTEST trial as an example of an RRCT. We also give some examples from other disease areas. The RRCT concept is a novel, cost-effective and scientifically sound approach for conducting large-scale diabetes trials in a real-world setting.

Abstract
OBJECTIVE To study the association of personalised care plans with monitoring and controlling clinical outcomes, prescription of cardiovascular and antihyperglycaemic medication and utilisation of primary care services in patients with type 2 diabetes (T2D). PATIENTS Primary care T2D outpatients from the Rovaniemi Health Centre. SETTING The municipal health centre, Rovaniemi, Finland. DESIGN A cross-sectional, observational, retrospective register-based study. The patients were divided into three groups: 'no care plan entries' (usual care); '1-2 care plan entries'; and '3 or more care plan entries'. MAIN OUTCOME MEASURES Monitoring of clinical and biochemical measures, achievement of treatment targets, prescription of cardiovascular and antihyperglycemic medication, and use of primary care services. RESULTS A total of 5104 patients with T2D (mean age 65.5 years (SD 12.4)), of which 67% had at least one care plan entry. Compared to usual care, the establishment of a care plan (either care plan group) was associated with better monitoring of glycosylated haemoglobin A1c, low-density-lipoprotein cholesterol, systolic blood pressure (sBP), and renal function, and there was more frequent prescription of all cardiovascular and antihyperglycemic medication. Patients in either care plan group were more likely to achieve sBP target (p < 0.05). Patients without a care plan had more unplanned primary care physician contacts compared to patients in care plan groups (p < 0.001). CONCLUSION Establishment of a care plan is associated with more intensive and focussed care of patients with T2D. The appropriate use of primary care resources is essential and personalised care plans may contribute to the treatment of patients with T2D.Key PointsCare planning aims to empower patients with type 2 diabetes. This study demonstrates that personalised care planning is associated withmore frequent monitoring for clinical outcomes,more frequent prescription of cardiovascular and antihyperglycemic medication andmore frequent utilisation of planned diabetes consultations when compared to usual care.

Abstract
RATIONALE, AIMS AND OBJECTIVES Applying traditional industrial quality improvement (QI) methodologies to primary care is often inappropriate because primary care and its relationship to the healthcare macrosystem has many features of a complex adaptive system (CAS) that is particularly responsive to bottom-up rather than top-down management approaches. We report on a demonstration case study of improvements made in the Family Health Center (FHC) of the JPS Health Network in a refugee patient population that illustrate features of QI in a CAS framework as opposed to a traditional QI approach. METHODS We report on changes in health system utilization by new refugee patients of the FHC from 2016 to 2017. We review the literature and summarize relevant theoretical understandings of quality management in complex adaptive systems as it applies to this case example. RESULTS Applying CAS principles in the FHC, utilization of the Emergency Department and Urgent Care Center by newly arrived refugee patients before their first clinic visit was reduced by more than half (total visits decreased from 31%-14% of the refugee patients). Our review of the literature demonstrates that traditional algorithmic top-down QI processes are most often unsuccessful in improving even a few single-disease metrics, and increases clinician burnout and penalizes clinicians who care for vulnerable patients. Improvement in a CAS occurs when front-line clinicians identify care gaps and are given the flexibility to learn and self-organize to enable new care processes to emerge, which are created from bottom-up leadership that utilize existing interdependencies and interact with the top levels of the organization through intelligent top-down causation. We give examples of early adapters who are better applying the principles of CAS change to their QI efforts. CONCLUSIONS Meaningful improvement in primary care is more likely achieved when the impetus to implement change shifts from top-down to bottom-up.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) causes both macrovascular and microvascular complications. However, currently, selection of glycemic measures and their thresholds to diagnose T2DM, and efficacy outcomes in evaluation of anti-diabetic drugs is predominantly informed by the relation of T2DM to microvascular complications. We can be severely mistaken on T2DM by neglecting macrovascular complications which are generally more severe, if they also occur more commonly than microvascular complications.
AIM To compare the incidence of major cardiovascular events (MACEs) and severe microvascular complications (SMICs) in T2DM patients.
METHODS MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials were searched from inception to September 2017. Cohort studies or trials of T2DM patients aged 18 years or older that reported incidence of both MACEs and SMICs were included. MACEs were defined as nonfatal myocardial infarction and stroke, and cardiovascular death, while SMICs included serious retinopathy, nephropathy and diabetic disorder. The relative risk (RR) was estimated as the incidence of MACEs divided by that of SMICs in same patients and combined with meta-analysis in a random-effect model.
RESULTS Twelve studies with a total of 16 cohorts and 387376 patients were included, and the combined RR was 2.02 (95%CI: 1.46–2.79). The higher incidence of MACEs remained in various subgroup and sensitivity analyses.
CONCLUSION Patients with T2DM are much more likely to develop MACEs than SMICs. By taking more serious consequences and relatively higher incidence into consideration, macrovascular complications deserve more emphasis in developing the diagnostic criteria of T2DM and in evaluating the efficacy of anti-diabetic drugs.

Abstract
The restricted mean survival time (RMST) has been advocated as an alternative or a supplement to the hazard ratio for reporting the effect of an intervention in a randomized clinical trial. The RMST difference allows quantification of the postponement of an outcome during a specified (restricted) interval and corresponds to the difference between the areas under the 2 survival curves for the intervention and control groups. This article presents examples of the use of the RMST in a research and a clinical context. First, the authors demonstrate how the RMST difference can answer research questions about the efficacy of different treatments. Estimates are presented for the effects of pharmacologic or strategy-driven glucose-lowering interventions for adults with type 2 diabetes from 36 trials and 9 follow-up studies reporting cardiovascular outcomes and mortality. The authors show how these measures may be used to mitigate uncertainty about the efficacy of intensive glucose control. Second, the authors demonstrate how the RMST difference may be used in the setting of a clinical consultation to guide the decision to start or discontinue a treatment. They then discuss the advantages of the RMST over the absolute risk difference, the number needed to treat, and the median survival time difference. They argue that the RMST difference is both easy to interpret and flexible in its application to different settings. Finally, they highlight the major limitations of the RMST, including difficulties in comparing studies of heterogeneous designs and in inferring the long-term effects of treatments using trials of short duration, and summarize the available statistical software for calculating the RMST.

To analyze the association between change in HbA1c during the first 6 years after diagnosis of Type 2 diabetes mellitus (Type 2 DM) and incident micro- and macrovascular morbidity and mortality during 13 years thereafter. This is an observational study of the participants in the intervention arm of the randomized controlled trial Diabetes Care in General Practice (DCGP) in Denmark. 494 newly diagnosed persons with Type 2 DM aged 40 years and over with three or more measurements of HbA1c during six years of intervention were included in the analyses. Based on a regression line, fitted through the HbA1c-measurements from 1 to 6 years after diabetes diagnosis, glycaemic control was characterized by the one-year level of HbA1c after diagnosis, and the slope of the regression line. Outcomes were incident diabetes-related morbidity and mortality from 6 to 19 years after diabetes diagnosis. The association between change in HbA1c (the slope of the regression line) and clinical outcomes were assessed in adjusted Cox regression models. The median HbA1c level at year one was 60 (IQR: 52–71) mmol/mol or (7.65 (IQR: 6.91–8.62) %). Higher HbA1c levels one year after diagnosis were associated with a higher risk of later diabetes-related morbidity and mortality. An increase in HbA1c during the first 6 years after diabetes diagnosis was associated with later microvascular complications (HR per 1.1 mmol/mol or 0.1% point increase in HbA1c per year; 95% CI) = 1.14; 1.05–1.24). Change in HbA1c did not predict the aggregate outcome ‘any diabetes-related endpoint, all-cause mortality, diabetes-related mortality, myocardial infarction, stroke, or peripheral vascular diseases. We conclude that suboptimal development of glycaemic control during the first 6 years after diabetes diagnosis was an independent risk factor for microvascular complications during the succeeding 13-year follow-up, but not for mortality or macrovascular complications.

Abstract
BACKGROUND Survival from many cancer types is steadily increasing, and as a result, a growing number of cancer patients will live with other chronic diseases, of which diabetes is one of the most prevalent. This study aims to describe the impact of cancer on health outcomes in patients with type 2 diabetes and to compare the effectiveness of a multifactorial intervention in diabetes patients with and without cancer. METHODS The randomized controlled trial Diabetes Care in General Practice (DCGP) included 1381 patients newly diagnosed with type 2 diabetes. Patients were randomized to either six years of structured personal diabetes care or routine care. In a post hoc analysis, we followed patients for 19 years in Danish national registries for the occurrence of diabetes-related outcomes. We used Cox regression models to estimate hazard ratios for outcomes. RESULTS At diagnosis 48 patients had cancer, and 243 patients were diagnosed with cancer during follow up. Patients with diabetes and cancer had excess all-cause mortality (HR 3.33; 95%CI 2.72-4.06), as well as an increased incidence of myocardial infarction (HR 1.76; 95%CI 1.29-2.39) and any diabetes-related outcome (HR 1.36; 95%CI 1.07-1.71). The intervention reduced the risk of both these endpoints in patients without cancer. Furthermore, there was no statistically significant difference in the effectiveness of the intervention among patients with and without cancer. CONCLUSIONS Diabetes patients with cancer had an increased risk of myocardial infarction and any diabetes-related outcome. The observed positive effect of structured personal diabetes care on clinical outcomes did not differ between patients with and without cancer. Attention to and prevention of diabetes complications in patients with both type 2 diabetes and cancer is warranted. TRIAL REGISTRATION ClinicalTrials.gov NCT01074762 (February 24, 2010).

Abstract
AIMS The urinary marker of RNA oxidation, 8‑oxo‑7,8‑dihydroguanosine (8-oxoGuo), but not the corresponding marker of DNA oxidation, 8‑oxo‑7,8‑dihydro‑2'‑deoxyguanosine (8-oxodG), is a prognostic biomarker in patients with type 2 diabetes (T2D). The aim of the present study was to investigate the effect of structured personal care (individualized multifactorial treatment) versus standard care on RNA oxidation level in patients with T2D and to assess if the effect of structured personal care on all-cause and diabetes-related mortality was modified by RNA oxidation level. METHODS Urine samples were analyzed for 8-oxoGuo/8-oxodG from 1381 newly diagnosed T2D patients from the cluster randomized trial Diabetes Care in General Practice cohort, and 970 patients were reexamined after six years of intervention. RESULTS The yearly variation in RNA oxidation levels were not significantly different between the structured personal care group and standard care group. The effect of treatment on all-cause and diabetes-related mortality was not modified by the level of RNA oxidation. No changes in DNA oxidation were seen. CONCLUSIONS Structured personal care does not influence RNA oxidation level nor is it better for patients with high RNA oxidation level. Thus, structured personal care may not impact the disease-related aspects identified by RNA oxidation level in T2D patients.

Abstract
PURPOSE The multidisciplinary Risk Assessment and Management Program for patients with diabetes mellitus (RAMP-DM) was found to be cost-saving in comparison with usual primary care over 5 years' follow-up. This study aimed to estimate the cost-effectiveness of RAMP-DM over lifetime. METHODS We built a Discrete Event Simulation model to evaluate the cost-effectiveness of RAMP-DM over lifespan from public health service provider's perspective. Transition probabilities among disease states were extrapolated from a cohort of 17,140 propensity score matched participants in RAMP-DM and those under usual primary care over 5-year's follow-up. The mortality of patients with specific DM-related complications was estimated from a cohort of 206,238 patients with diabetes. Health preference and direct medical costs of DM patients referred to our previous studies among Chinese DM patients. RESULTS RAMP-DM individuals gained 0.745 QALYs and cost US$1404 less than those under usual care. The probabilistic sensitivity analysis found that RAMP-DM had 86.0% chance of being cost-saving compared to usual care under the assumptions and estimates used in the model. The probability of RAMP-DM being cost-effective compared to usual care would be over 99%, when the willingness to pay threshold is HK$20,000 (US$ 2564) or higher. CONCLUSION RAMP-DM added to usual primary care was cost-saving in managing people with diabetes over lifetime. These findings support the integration of RAMP-DM as part of routine primary care for all patients with diabetes.

Abstract
OBJECTIVE To evaluate whether visual acuity impairment was an independent predictor of mortality in patients with type 2 diabetes. RESEARCH DESIGN AND METHODS This is a 19-year follow-up of a cohort of 1241 patients newly diagnosed with type 2 diabetes and aged 40 years or over. Visual acuity was assessed by practicing ophthalmologists both at diabetes diagnosis and after 6 years. The logarithmic value of the visual acuity (logMAR) was the exposure. Multivariable Cox regression models were adjusted for multiple potential confounders including cardiovascular disease, and censored for potential mediators, that is, fractures/trauma. Primary outcomes were from national registers: all-cause mortality and diabetes-related mortality. RESULTS Visual impairment at diabetes diagnosis was robustly associated with subsequent 6-year all-cause mortality. Per 1 unit reduced logMAR acuity the incidence rate of all-cause mortality increased with 51% (adjusted HR: 1.51; 95% CI 1.12 to 2.03) and of fractures/trauma with 59% (HR: 1.59; 95% CI 1.18 to 2.15), but visual acuity was not associated with diabetes-related mortality. After censoring for fractures/trauma, visual acuity was still an independent risk factor for all-cause mortality (HR: 1.68; 95% CI 1.23 to 2.30). In contrast, visual acuity 6 years after diabetes diagnosis was not associated with the subsequent 13 years' incidence of any of the outcomes, as an apparent association with all-cause mortality and diabetes-related mortality was explained by confounding from comorbidity. CONCLUSIONS Visual acuity measured by ophthalmologists in patients newly diagnosed with type 2 diabetes was an independent predictor of mortality in the short term.

Abstract
Importance Follow-up of participants in randomized trials may be limited by logistic and financial factors. Some important randomized trials have been extended well beyond their original follow-up period by linkage of individual participant information to routinely collected data held in administrative records and registries. Objective To perform a scoping review of randomized clinical trials extended by record linkage to characterize this literature and explore any additional insights into treatment effectiveness provided by long-term follow-up using record linkage. Data Sources A literature search in Embase, CINAHL, MEDLINE, and the Cochrane Register of Controlled Trials was performed for the period January 1, 1945, through November 25, 2016. Study Selection Various combinations of search terms were used, as there is no accepted terminology. Determination of study eligibility and extraction of information about trial characteristics and outcomes, for both original and extended trial reports, were performed in duplicate. Data Extraction and Synthesis Assessment of study eligibility and data extraction were performed independently by 2 reviewers. All analyses were descriptive. Main Outcomes and Measures Outcomes in the pairs of original and extended trials were categorized according to whether any benefits or harms from interventions were sustained, were lost, or emerged during long-term follow-up. Results A total of 113 extended trials were included in the study. Linkage to administrative and registry data extended follow-up by between 1 and 55 years. The most common interventions were pharmaceuticals (47 [41.6%]), surgery (19 [16.8%]), and disease screening (19 [16.8%]). End points most frequently studied through record linkage included mortality (88 [77.9%]), cancer (41 [36.3%]), and cardiovascular events (37 [32.7%]). One hundred four trial extensions (92.0%) were analyzed according to the original trial randomization. The reports provided details of 155 analyses of study outcomes. Seventy-four analyses (47.7%) identified statistically significant benefits in the trial extension phase. In 21 of these (28.4%), benefits were significant only in this period. Null results in both the original and extended trials were seen in 34 of the analyses (21.9%). Loss of significant benefits of an intervention were seen in 12 analyses (7.7%). Statistically significant harms were seen in 16 trial extension analyses (10.3%), and in 14 of these (87.5%), the harms were significant only in the trial extension phase. Conclusions and Relevance Trial extension by linkage to routinely collected data is a versatile underused approach that may add critical insights beyond those of the original trial. Some beneficial and harmful outcomes of interventions are captured only in the extension phase of randomized trials.

Abstract
Objective: The aims of this study were to (1) quantify the development and composition
of multimorbidity (MM) during 16 years following the diagnosis of type 2
diabetes and (2) evaluate whether the effectiveness of structured personal
diabetes care differed between patients with and without MM. Research design and methods: One thousand three hundred eighty-one patients with newly diagnosed type 2
diabetes were randomized to receive either structured personal diabetes care
or routine diabetes care. Patients were followed up for 19 years in Danish
nationwide registries for the occurrence of outcomes. We analyzed the
prevalence and degree of MM based on 10 well-defined disease groups. The
effect of structured personal care in diabetes patients with and without MM
was analyzed with Cox regression models. Results: The proportion of patients with MM increased from 31.6% at diabetes diagnosis
to 80.4% after 16 years. The proportion of cardiovascular and
gastrointestinal diseases in surviving patients decreased, while, for
example, musculoskeletal, eye, and neurological diseases increased. The
effect of the intervention was not different between type 2 diabetes
patients with or without coexisting chronic disease. Conclusions: In general, the proportion of patients with MM increased after diabetes
diagnosis, but the composition of chronic disease changed during the 16
years. We found cardiovascular and musculoskeletal disease to be the most
prevalent disease groups during all 16 years of follow-up. The post hoc
analysis of the intervention showed that its effectiveness was not different
among patients who developed MM compared to those who continued to have
diabetes alone.

Abstract
AIMS To explore the effect of structured personal care on diabetes symptoms and self-rated health over 14 years after diabetes diagnosis while patients are gradually diagnosed with other chronic conditions (multimorbidity). METHODS Post hoc analysis of the Danish randomized controlled trial Diabetes Care in General Practice including 1381 patients newly diagnosed with type 2 diabetes. The effect of structured personal care compared with routine care on diabetes symptoms and self-rated health was analysed 6 and 14 years after diagnosis with a generalized multilevel Rasch model. RESULTS Structured personal care reduced the overall likelihood of reporting diabetes symptoms at the end of the intervention (OR 0.79; 95% CI: 0.64-0.97), but this effect was not explained by glycaemic control or multimorbidity. There was no effect of the intervention on diabetes symptoms after 14 years or on self-rated health after 6 years or 14 years. CONCLUSIONS Structured personal care had a beneficial effect on diabetes symptoms 6 years after diagnosis, but not on self-rated health at either follow up point. To optimally manage patients over time it is important to supplement clinical information by information provided by the patients.

[PMID: 28925010 DOI: 10.1002/dmrr.2952] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2017] [Revised: 08/24/2017] [Accepted: 09/10/2017] [Indexed: 01/01/2023]
Abstract
BACKGROUND This study examined whether temporal trends exist in treatment of patients with type 2 diabetes (T2D) and quality of diabetes care after implementation of quality improvement initiative in primary care setting. METHODS We conducted a population-based retrospective cohort study of 202,284 patients with T2D who were routinely managed in primary care clinics. We examined the change over time and the variability between clinics in quality of care from Hospital Authority administrative data over a 5-year period (2009-2013) and used multilevel logistic regression to adjust for patient and clinic characteristics. Observational period was partitioned in 5 calendar years. Ten quality-of-care criteria were selected: adherence to 7 process of care criteria (HbA1c test, renal function test, full lipid profile, urine protein analysis, retinal screening, lipid-lowering agent prescriptions among patients with hypercholesterolaemia, and angiotensin converting enzyme inhibitor/angiotensin receptor blocker prescriptions among patients with microalbuminuria) and 3 outcome of care criteria (HbA1c ≤ 7%, BP ≤ 130/80 mmHg, and LDL-C ≤ 2.6 mmol/L). Variability of standards between clinics was assessed by using intracluster correlation coefficients. RESULTS Characteristics of patients with T2D managed in primary care changed substantially during the observational period, with increasing age and usage of insulin and longer duration of diabetes but improved metabolic profiles (all P trend < .001). Performance rates of the 7 process and 3 clinical outcomes of care criteria increased remarkably over time (all P trend < .001). Variations in retinal screening delivery between clinics were considerable, albeit decreasing over time. CONCLUSIONS Coinciding with implementation of quality improvement initiative, quality of diabetes care improved significantly in the past 5 years, in part attributable to benefits of integrated multidisciplinary diabetes management.

Abstract
OBJECTIVE To estimate the cost-effectiveness of the multidisciplinary Risk Assessment and Management Programme-Diabetes Mellitus (RAMP-DM) in primary care patients with type 2 diabetes in comparison with usual primary care in a cohort with 5 years' follow-up. RESEARCH DESIGN AND METHODS We conducted a prospective cohort study among 17,140 propensity score-matched participants in RAMP-DM and those under usual primary care. The effectiveness measures were cumulative incidences of complications and all-cause mortality over 5 years. In a bottom-up approach, we estimated the program costs of RAMP-DM and health service utilization from the public health service provider's perspective. The RAMP-DM program costs included the setup costs, ongoing intervention costs, and central administrative costs. We calculated the incremental cost-effectiveness ratio by dividing the incremental costs by the incremental effectiveness of the RAMP-DM group compared with those of the usual-care group. RESULTS There were significantly lower cumulative incidences of individual on any complications (15.34% vs. 28.65%, P < 0.001) and all-cause mortality (7.96% vs. 21.35%, P < 0.001) in the RAMP-DM group compared with the usual-care group. The mean program cost of RAMP-DM was 157 U.S. dollars (range 66-209) per participant over 5 years. The costs of health service utilization among participants in RAMP-DM group was 7,451 USD less than that of the usual-care group, resulting in a net savings of 7,294 USD per individual. CONCLUSIONS RAMP-DM added to usual primary care was a cost-saving intervention in managing diabetes in patients over 5 years. These findings support the integration of RAMP-DM as part of routine primary care for all patients with diabetes.

Abstract
BACKGROUND We investigated how four aspects of socio-demography influence the effectiveness of an intervention with structured personal diabetes care on long-term outcomes. METHODS The Diabetes Care in General Practice (DCGP) study is a cluster-randomized trial involving a population-based sample of 1381 patients with newly diagnosed type 2-diabetes mellitus. We investigated how education, employment, cohabitation status and residence influenced the effectiveness of 6 years of intervention with structured personal diabetes care, resembling present day recommendations. Outcomes were incidence of any diabetes-related endpoint and death during 19 years after diagnosis, and cardiovascular risk factors, behaviour, attitudes and process-of-care variables 6 years after diagnosis. RESULTS Structured personal care reduced the risk of any diabetes-related endpoint and the effect of the intervention was modified by geographical area (interaction p = 0.034) with HR of 0.71 (95%CI: 0.60-0.85) and of 1.07 (95%CI: 0.77-1.48), for patients in urban and rural areas, respectively. Otherwise, there was no effect modification of education, employment and civil status on the intervention for the final endpoints. There were no noticeable socio-demographic differences in the effect of the intervention on cardiovascular risk factors, behaviour, attitudes, and process-of-care. CONCLUSION Structured personal care reduced the aggregate outcome of any diabetes-related endpoint and independent of socio-demographic factors similar effect on cardiovascular risk factors, behaviour, attitudes and process of care, but the intervention did not change the existing inequity in mortality and morbidity. Residence modified the uptake of the intervention with patients living in urban areas having more to gain of the intervention than rural patients, further investigations is warranted.

Abstract
IN BRIEF Caring for people with type 2 diabetes requires a patient-centered approach to treatment targets and medication regimens. Focusing on patients' individual characteristics, needs, and treatment responses can improve compliance and clinical outcomes. Medication selection can be guided by the mechanisms of action, advantages, disadvantages, and costs of available options; patients' behavioral and psychological variables, personal preferences, and socioeconomic status also should be taken into account. This article provides an overview of patient-centered and individualized diabetes management, offers pharmacological recommendations for specific clinical scenarios, and describes a complicated case illustrating the patient-centered approach in clinical practice.

Intra-cluster and inter-period correlation coefficients for cross-sectional cluster randomised controlled trials for type-2 diabetes in UK primary care. Trials 2016; 17:402. [PMID: 27524396 PMCID: PMC4983799 DOI: 10.1186/s13063-016-1532-9] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2015] [Accepted: 07/30/2016] [Indexed: 11/23/2022] Open
Abstract
Background Clustered randomised controlled trials (CRCTs) are increasingly common in primary care. Outcomes within the same cluster tend to be correlated with one another. In sample size calculations, estimates of the intra-cluster correlation coefficient (ICC) are needed to allow for this nonindependence. In studies with observations over more than one time period, estimates of the inter-period correlation (IPC) and the within-period correlation (WPC) are also needed. Methods This is a retrospective cross-sectional study of all patients aged 18 or over with a diagnosis of type-2 diabetes, from The Health Improvement Network (THIN) database, between 1 October 2007 and 31 March 2010. We report estimates of the ICC, IPC, and WPC for typical outcomes using unadjusted and adjusted generalised linear mixed models with cluster and cluster by period random effects. For binary outcomes we report on the proportions scale, which is the appropriate scale for trial design. Estimated ICCs were compared to those reported from a systematic search of CRCTs undertaken in primary care in the UK in type-2 diabetes. Results Data from 430 general practices, with a median [IQR] number of diabetics per practice of 241 [150–351], were analysed. The ICC for HbA1c was 0.032 (95 % CI 0.026–0.038). For a two-period (each of 12 months) design, the WPC for HbA1c was 0.035 (95 % CI 0.030–0.040) and the IPC was 0.019 (95 % CI 0.014–0.026). The difference between the WPC and the IPC indicates a decay of correlation over time. Following dichotomisation at 7.5 %, the ICC for HbA1c was 0.026 (95 % CI 0.022–0.030). ICCs for other clinical measurements and clinical outcomes are presented. A systematic search of ICCs used in the design of CRCTs involving type-2 diabetes with HbA1c (undichotomised) as the outcome found that published trials tended to use more conservative ICC values (median 0.047, IQR 0.047–0.050) than those reported here. Conclusions These estimates of ICCs, IPCs, and WPCs for a variety of outcomes commonly used in diabetes trials can be useful for the design of CRCTs. In studies with observations taken at different time-points, the correlation of observations may decay over time, as reflected in lower values for the IPC than for the ICC. The IPC and WPC estimates are the first reported for UK primary care data.

The impact of gender on the long-term morbidity and mortality of patients with type 2 diabetes receiving structured personal care: a 13 year follow-up study. Diabetologia 2016; 59:275-85. [PMID: 26607637 DOI: 10.1007/s00125-015-3804-4] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2015] [Accepted: 10/19/2015] [Indexed: 12/15/2022]
Abstract
AIMS/HYPOTHESIS The aim of this study was to assess gender differences in mortality and morbidity during 13 follow-up years after 6 years of structured personal care in patients with type 2 diabetes mellitus. METHODS In the Diabetes Care in General Practice (DCGP) multicentre, cluster-randomised, controlled trial (ClinicalTrials.gov registration no. NCT01074762), 1,381 patients newly diagnosed with type 2 diabetes were randomised to receive 6 years of either structured personal care or routine care. The intervention included regular follow-up, individualised goal setting and continuing medical education of general practitioners participating in the intervention. Patients were re-examined at the end of intervention. This observational analysis followed 970 patients for 13 years thereafter using national registries. Outcomes were all-cause mortality, incidence of diabetes-related death, any diabetes-related endpoint, myocardial infarction, stroke, peripheral vascular disease and microvascular disease. RESULTS In women, but not men, a lower HR for structured personal care vs routine care emerged for any diabetes-related endpoint (0.65, p = 0.004, adjusted; 73.4 vs 107.7 events per 1,000 patient-years), diabetes-related death (0.70, p = 0.031; 34.6 vs 45.7), all-cause mortality (0.74, p = 0.028; 55.5 vs 68.5) and stroke (0.59, p = 0.038; 15.6 vs 28.9). This effect was different between men and women for diabetes-related death (interaction p = 0.015) and all-cause mortality (interaction p = 0.005). CONCLUSIONS/INTERPRETATION Compared with routine care, structured personal diabetes care reduced all-cause mortality and diabetes-related death in women but not in men. This gender difference was also observed for any diabetes-related outcome and stroke but was not statistically significant after extensive multivariate adjustment. These observational results from a post hoc analysis of a randomised controlled trial cannot be explained by intermediate outcomes like HbA1c alone, but involves complex social and cultural issues of gender. There is a need to rethink treatment schemes for both men and women to gain benefit from intensified treatment efforts.

Intentional Weight Loss and Longevity in Overweight Patients with Type 2 Diabetes: A Population-Based Cohort Study. PLoS One 2016; 11:e0146889.

Abstract
Objective This study examined the influence of weight loss on long-term morbidity and mortality in overweight (BMI≥25kg/m2) patients with type 2 diabetes, and tested the hypothesis that therapeutic intentional weight loss supervised by a medical doctor prolongs life and reduces the risk for cardiovascular disease in these patients. Methods This is a 19 year cohort study of patients in the intervention arm of the randomized clinical trial Diabetes Care in General Practice. Weight and prospective intentions for weight loss were monitored every third month for six years in 761 consecutive patients (≥40 years) newly diagnosed with diabetes in general practices throughout Denmark in 1989–92. Multivariable Cox regression was used to estimate the association between weight change during the monitoring period (year 0 to 6) and the outcomes during the succeeding 13 years (year 6 to 19) in 444 patients who were overweight at diagnosis and alive at the end of the monitoring period (year 6). The analysis was adjusted for age, sex, education, BMI at diagnosis, change in smoking, change in physical activity, change in medication, and the Charlson comorbidity 6-year score. Outcomes were from national registers. Results Overall, weight loss regardless of intention was an independent risk factor for increased all-cause mortality (P<0.01). The adjusted hazard ratio for all-cause mortality, cardiovascular mortality, and cardiovascular morbidity attributable to an intentional weight loss of 1 kg/year was 1.20 (95%CI 0.97–1.50, P = 0.10), 1.26 (0.93–1.72, P = 0.14), and 1.06 (0.79–1.42, P = 0.71), respectively. Limiting the analysis to include only those patients who survived the first 2 years after the monitoring period did not substantially change these estimates. A non-linear spline estimate indicated a V-like association between weight change and all-cause mortality, suggesting the best prognosis for those who maintained their weight. Conclusions In this population-based cohort of overweight patients with type 2 diabetes, successful therapeutic intentional weight loss, supervised by a doctor over six years, was not associated with reduced all-cause mortality or cardiovascular morbidity/mortality during the succeeding 13 years.

Abstract
OBJECTIVE To assess the effectiveness of an intervention in Type 2 diabetic patients with concurrent psychiatric illness (PI) and compare this with the effectiveness in patients without PI. METHOD In the Diabetes Care in General Practice trial, 1381 patients newly diagnosed with Type 2 diabetes were randomized to 6 years of structured personal diabetes care or routine diabetes care (ClinicalTrials.gov NCT01074762). In this observational post-hoc analysis, the effectiveness of the intervention for diabetes in 179 patients with concurrent PI was analyzed. RESULTS During the 19-year follow-up period, patients with PI in the structured personal care group experienced a lower risk for all-cause mortality [105.3 vs. 140.4 events per 1000 patient-years; hazard ratio (HR): 0.63, P=0.023, multivariably adjusted], diabetes-related death (66.0 vs. 95.1; HR: 0.57, P=0.015), any diabetes-related endpoint (169.5 vs. 417.5; HR: 0.47, P=0.0009) and myocardial infarction (54.1 vs. 104.4; HR: 0.48, P=0.013), compared to patients with PI in the routine care group. This translates into a number needed to treat over 10 years of three or lower for these outcomes. CONCLUSION These findings suggest that in primary care, structured diabetes care allowing for individualization was highly effective among diabetic patients with co-occurring PI.

Abstract
BACKGROUND Studies on the long-term effectiveness of multidisciplinary risk-stratification based management in Chinese population were rare. This study aimed to evaluate the effectiveness of a multidisciplinary risk assessment and management program for patients with diabetes mellitus (RAMP-DM) in reducing the risks of cardiovascular complications and all-cause mortality. METHODS A prospective cohort study was conducted in 18,188 propensity score matched RAMP-DM participants and subjects with diabetes under usual primary care (9,094 subjects in each group). The study endpoints were the first occurrence of coronary heart disease (CHD), stroke, heart failure (HF), total cardiovascular disease (CVD) and all-cause mortality. We constructed multivariable Cox proportional hazard regressions to estimate the association between the RAMP-DM intervention and the first occurrence of study endpoints. RESULTS The median follow-up period was 36 months. Three hundred and ninety-nine CVD events occurred in the RAMP-DM group, as compared with 608 in the control group [adjusted hazard ratio, 0.629; 95% confidence interval (CI) 0.554-0.715; P < 0.001]. The total number of all-cause deaths in RAMP-DM group was less than half that of control group (202 vs 552, adjusted hazard ratio, 0.363; 95% CI, 0.308-0.428; P < 0.001). The adjusted hazard ratios of the RAMP-DM group for CHD, stroke, and HF were 0.570 (95% CI, 0.470-0.691; P < 0.001), 0.652 (95% CI, 0.546-0.780; P < 0.001), and 0.598 (95%CI, 0.446-0.802; P = 0.001), respectively. CONCLUSIONS The RAMP-DM intervention was associated with lower incidences of individual and total cardiovascular complications, as well as all-cause mortality over 3 years follow-up. The encouraging results provided evidence to support that the structured risk-stratification management leading by a multidisciplinary clinical team was an effective approach to reduce future cardiovascular complications in people with diabetes.

Early glycaemic control among patients with type 2 diabetes and initial glucose-lowering treatment: a 13-year population-based cohort study. Diabetes Obes Metab 2015; 17:771-80. [PMID: 25929277 DOI: 10.1111/dom.12484] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2015] [Revised: 04/14/2015] [Accepted: 04/28/2015] [Indexed: 11/29/2022]
Abstract
AIM To examine real-life time trends in early glycaemic control in patients with type 2 diabetes between 2000 and 2012. METHODS We used population-based medical databases to ascertain the association between achievement of glycaemic control with initial glucose-lowering treatment in patients with incident type 2 diabetes in Northern Denmark. Success in reaching glycated haemoglobin (HbA1c) goals within 3-6 months was examined using regression analysis. RESULTS Of 38 418 patients, 91% started with oral glucose-lowering drugs in monotherapy. Metformin initiation increased from 32% in 2000-2003 to 90% of all patients in 2010-2012. Pretreatment (interquartile range) HbA1c levels decreased from 8.9 (7.6-10.7)% in 2000-2003 to 7.0 (6.5-8.1)% in 2010-2012. More patients achieved an HbA1c target of <7% (<53 mmol/mol) in 2010-2012 than in 2000-2003 [80 vs 60%, adjusted relative risk (aRR) 1.10, 95% confidence interval (CI) 1.08-1.13], and more achieved an HbA1c target of <6.5% [(<48 mmol/mol) 53 vs 37%, aRR 1.07 95% CI 1.03-1.11)], with similar success rates observed among patients aged <65 years without comorbidities. Achieved HbA1c levels were similar for different initiation therapies, with reductions of 0.8% (from 7.3 to 6.5%) on metformin, 1.5% (from 8.1 to 6.6%) on sulphonylurea, 4.0% (from 10.4 to 6.4%) on non-insulin combination therapies, and 3.8% (from 10.3 to 6.5%) on insulin monotherapy. CONCLUSIONS Pretreatment HbA1c levels in patients with incident type 2 diabetes have decreased substantially, which is probably related to earlier detection and treatment in accordance with changing guidelines. Achievement of glycaemic control has improved, but 20% of patients still do not attain an HbA1c level of <7% within the first 6 months of initial treatment.

The impact of patients' involvement in cooking on their mortality and morbidity: a 19-year follow-up of patients diagnosed with type 2 diabetes mellitus. Scand J Prim Health Care 2015; 33:33-9. [PMID: 25592166 PMCID: PMC4377735 DOI: 10.3109/02813432.2015.1001940] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2014] [Accepted: 11/30/2014] [Indexed: 01/25/2023] Open
Abstract
OBJECTIVE This study explored the impact of involvement in cooking on long-term morbidity and mortality among patients newly diagnosed with type 2 diabetes mellitus (T2DM). DESIGN AND SUBJECTS Data are from the population-based study Diabetes Care in General Practice. In baseline questionnaires, 1348 patients newly diagnosed with T2DM gave information on how frequently they consumed a warm main meal and how often they cooked it themselves. The selected patients were followed up for 19 years in the Danish National Patient Registry and the Danish Register of Causes of Death. MAIN OUTCOME MEASURES This study analysed the association between involvement in cooking and each of seven pre-specified outcomes was analysed in Cox regression models with stepwise adjustment for possible confounders and mediators. RESULTS 92% of the patients with T2DM consumed a warm main meal ≥ five times per week. Among these, women who cooked for themselves less than once a week had a higher risk of diabetes-related deaths (HR 1.86 [95% CI 1.03-3.35], p = 0.039) and stroke (HR 2.47 [95% CI 1.08-5.65], p = 0.033), after adjustment for confounders. For men, infrequent cooking was not related to increased risk for the outcomes investigated. CONCLUSIONS In patients newly diagnosed with T2DM and with a regular intake of warm main meals, infrequent involvement in cooking was associated with an increased risk of diabetes-related death and stroke for women, but not for men. General practitioners should pay special attention to managing diabetes treatment in female patients newly diagnosed with T2DM who report infrequent involvement in cooking.

Abstract
Objectives This study explored the views, barriers and facilitators of the poorly-educated elderly who were non-attendee of the nurse-led case manager clinic. The case managers provide assessment for diabetes complication screening and can refer patients to the appropriate multidisciplinary team in public outpatient primary care setting. Methods We adopted qualitative research method by individual semi-structured face to face interviews. Nineteen Chinese type 2 diabetes mellitus subjects aged ≥ 60 who failed to attend the nurse-led case manager clinic were interviewed. They all came from a socially deprived urban district in Hong Kong. Content and thematic analysis was performed. Results Seven men and twelve women aged 60 to 89 were interviewed. Nine of them received no formal education and ten of them attended up to primary school. The reasons for non-attendance included attitude and poor knowledge towards diabetes complication screening and confusion of the nurse-led clinic as an educational talk. Most respondents could not understand the reason for the screening of diabetic complications, the concept of multidisciplinary care and the procedure and outcomes of nurse assessment. Five respondents were unable to follow multiple appointments because they could not read. Other reasons included physical barriers and comorbidity, family and financial constraint. They either had a tight daily schedule because of the need to take care of family members, or the family members who brought them to clinic had difficulty in attending multiple appointments. Enhanced understanding of the importance and procedure of diabetes multidisciplinary management, a flexible appointment system and a single clear appointment sheet may facilitate their attendance. Conclusion Poorly-educated Chinese elderly with DM and their care givers faced physical, social and psychological barriers when attending the nurse-led case manager clinic. Strategies targeting on their low literacy include effective communication and education by health care professionals to arrive a shared understanding of care plan as well as a flexible appointment and schedule system.

BMC FAMILY PRACTICE 2014; 15:114.

Abstract
Background The general practitioner (GP) plays an important role for chronic disease care. Continuous and close contact with daytime general practice is intended to prevent medical problems arising outside office hours due to already diagnosed chronic disease. However, previous studies indicate that patients with chronic diseases are frequent users of out-of-hours primary care services (OOH), but knowledge is limited on reasons for encounter (RFE), severity of symptoms, and OOH patient handling. We aimed to describe contacts to the OOH services from patients with chronic heart disease, lung disease, severe psychiatric disorders, diabetes, and cancer in terms of RFE, OOH GP diagnosis, assessed severity of symptoms, and actions taken by the GP. Methods Eligible patients (aged 18 years and older) were randomly sampled from a one-year cross-sectional study comprising 15,229 contacts to the OOH services in the Central Denmark Region. A cohort of patients with one or more of the five selected chronic diseases were identified by linking data on the Danish civil registration number (CPR) through specific nationwide Danish health registers. Results Out of 13,930 identified unique patients, 4,912 had at least one of the five chronic diseases. In total, 25.9% of all calls to the OOH services came from this chronic disease patient group due to an acute exacerbation; 32.6% of these calls came from patients with psychiatric diagnoses. Patients with chronic disease were more likely to receive a face-to-face contact than the remaining group of patients, except for calls from patients with a psychiatric disorder who were more often completed through a telephone consultation. Patients with heart disease calling due to a new health problem formed the largest proportion of all OOH referrals to hospital (13.3%) compared to calls from the other groups with chronic disease (3.4-6.7%). Conclusions A third of the patients randomly sampled by their OOH call had one or more of the five selected chronic diseases (i.e. chronic lung disease, heart disease, diabetes, psychiatric disease, or cancer). Patients with chronic disease were more often managed by OOH GPs than other patients.

Abstract
AIMS/HYPOTHESIS The estimation of effect size in clinical trials commonly disregards recurrent outcomes. We investigated the effectiveness of a complex intervention on recurrent outcomes in patients with type 2 diabetes. METHODS In the Diabetes Care in General Practice (DCGP) randomised controlled trial, 1,381 patients newly diagnosed with type 2 diabetes were randomised to 6 years of structured personal care or routine care (ClinicalTrials.gov NCT01074762). The trial had 19 years of registry-based follow-up and was analysed with Cox regression models. Repeated occurrences in the same patient of outcomes (any diabetes-related endpoint, myocardial infarction [MI], stroke, peripheral vascular disease and microvascular disease) were accounted for with the Wei, Lin and Weissfeld method. RESULTS As previously shown, the intervention reduced the rates of first occurrence of both MI and any diabetes-related endpoint. However, for all outcomes, the HR for a second event showed a statistically non-significant tendency to be increased. We estimated a combined HR for all marginal failure times, regardless of whether they were first, second or later events. This showed that the intervention had no effect on the rate of any of the outcomes, including MI (HR 0.89, 95% CI 0.76, 1.05) and any diabetes-related endpoint (HR 0.98, 95% CI 0.87, 1.09). CONCLUSIONS/INTERPRETATION In the DCGP study, a smaller proportion of patients who received structured care experienced a first occurrence of MI or any diabetes-related endpoint compared with patients who received routine care. However, the patients who received structured care tended to experience more recurrent outcomes, so the total outcome rate was not affected by the intervention.

Abstract
Many type 2 diabetes mellitus patients have difficulties reaching optimal blood glucose control. With patients treated in primary care by nurses, nurse communication plays a pivotal role in supporting patient health. The twofold aim of the present review is to categorize common barriers to nurse–patient communication and to review potentially effective communication methods. Important communication barriers are lack of skills and self-efficacy, possibly because nurses work in a context where they have to perform biomedical examinations and then perform patient-centered counseling from a biopsychosocial approach. Training in patient-centered counseling does not seem helpful in overcoming this paradox. Rather, patient-centeredness should be regarded as a basic condition for counseling, whereby nurses and patients seek to cooperate and share responsibility based on trust. Nurses may be more successful when incorporating behavior change counseling based on psychological principles of self-regulation, for example, goal setting, incremental performance accomplishments, and action planning.

Abstract
BACKGROUND Structured diabetes care can improve outcomes and reduce risk of complications, but improving care in a deprived, ethnically diverse area can prove challenging. This report evaluates a system change to enhance diabetes care delivery in a primary care setting. METHODS All 35 practices in one inner London Primary Care Trust were geographically grouped into eight networks of four to five practices, each supported by a network manager, clerical staff and an educational budget. A multidisciplinary team developed a 'care package' for type 2 diabetes management, with financial incentives based on network achievement of targets. Monthly electronic performance dashboards enabled networks to track and improve performance. Network multidisciplinary team meetings including the diabetic specialist team supported case management and education. Key measures for improvement included the number of diabetes care plans completed, proportion of patients attending for digital retinal screen and proportions of patients achieving a number of biomedical indices (blood pressure, cholesterol, glycated haemoglobin). RESULTS Between 2009 and 2012, completed care plans rose from 10% to 88%. The proportion of patients attending for digital retinal screen rose from 72% to 82.8%. The proportion of patients achieving a combination of blood pressure ≤ 140/80 mm Hg and cholesterol ≤ 4 mmol/L rose from 35.3% to 46.1%. Mean glycated haemoglobin dropped from 7.80% to 7.66% (62-60 mmol/mol). CONCLUSIONS Investment of financial, organisational and education resources into primary care practice networks can achieve clinically important improvements in diabetes care in deprived, ethnically diverse communities. This success is predicated on collaborative working between practices, purposively designed high-quality information on network performance and engagement between primary and secondary care clinicians.
