Effectiveness of chronic care models for the management of type 2 diabetes mellitus in Europe: a systematic review and meta-analysis

Improving outcomes of type 2 diabetes mellitus patients in primary care with Chronic Care Model: A narrative review

Designed and implemented over two decades ago, the Chronic Care Model is a well-established chronic disease management framework that has steered several healthcare systems in successfully improving the clinical outcomes of patients with type 2 diabetes mellitus. Research evidence cements the role of the Chronic Care Model (with its six key elements of organization of healthcare delivery system, self-management support, decision support, delivery system design, clinical information systems, and community resources and policies) as an integrated framework to revamp the type 2 diabetes mellitus-related clinical practice and care that betters the patient care and clinical outcomes. The current review is an evidence-lit summary of importance of use of Chronic Care Model in primary care and their impact on clinical outcomes for patients afflicted with one of the most debilitating metabolic diseases, type 2 diabetes mellitus.

A 5-structured visits multidisciplinary clinical care approach to optimize the care of patients with type 2 diabetes: a pilot study

Introduction

Multidisciplinary coordinated care has been associated with improvement of diabetes care.

Aim and methods

This is a retrospective cohort analysis aimed to assess the effect of application of the five-structured visits Multi-disciplinary Clinical Care Approach (FMCA) on each of T2DM control, complications and comorbidities. The patients' records were assessed for one year of regular diabetes care followed with a year after implementation of FMCA for patients attending the diabetes clinic at Zulekha hospital. The patients were divided according to HbA1c (cutoff 7%) at the end of the FMCA year of follow-up into a group of controlled and another group of uncontrolled diabetes designated CDM and UCDM, respectively.

Results

49% of patients were males and the mean age was 44.22 years. HbA1c levels, LDL and urinary albumin/creatinine ratio (UACR) showed a marked decrease among the patients after implementation of FMCA (P = 0.02, P = 0.04, P = 0.003, respectively). Compared with an increase in the atherosclerotic cardiovascular risk score (ASCVD) during the regular period, exposure to FMCA significantly decreased the cardiovascular risk score (0.17%, 11.41%, P = 0.001, P = 0.001, respectively). A self-management score was significantly higher in CDM patients. After a multivariate regression analysis of factors affecting DM control, we detected that baseline HbA1c, UACR, self-management score and hospital admission rate were the most important factors to predict diabetes control.

Conclusion

The implementation of FMCA has shown a significant improvement in clinical and humanistic aspects of individuals with T2DM with a better outcome, more control and less complications.

A multicomponent health care intervention is associated with improved glycaemic control in subjects with poorly controlled type 2 diabetes compared with routine care: The INTEGRA study

AIM

The INTEGRA study evaluated whether a specially designed multicomponent health care intervention improved glycaemic control in subjects with poorly controlled type 2 diabetes compared with standard of care practice.

RESEARCH DESIGN AND METHODS

Pragmatic study in subjects from primary care centres with type 2 diabetes and glycated haemoglobin (HbA1c) >9% (75 mmol/mol). The multifaceted intervention (N = 225 subjects) included a diabetes-focused visit encouraging therapeutic intensification by health care professionals. Retrospective data from matched controls (N = 675) were obtained from electronic medical records of a primary care database. The primary outcome was to compare the change in HbA1c values between the groups at 12 months of follow-up.

RESULTS

The mean HbA1c decreased substantially in both groups after 3 months, and the mean reduction was significantly greater in the intervention group than in the usual care group after 12 months [mean difference -0.66% (-7 mmol/mol), 95% CI -0.4, -1.0; p < .001]. A larger percentage of participants in the intervention group achieved HbA1c <7% and <8% goals (15.5% vs. 5.3% and 29.3% vs. 13.5%, respectively; p < .001). The improvement in HbA1c levels was sustained throughout the study only in the intervention arm. Glucose-lowering therapy was more frequently intensified in patients in the intervention group at the initial and final time points of the study (between 0-3 and 6-12 months; p < .001), with a significant increase in the number of patients prescribed ≥2 antidiabetic therapies (p < .001).

CONCLUSIONS

A multifaceted intervention oriented at reducing therapeutic inertia by primary care physicians was associated with greater improvement in glycaemic control compared with patients treated as per usual care.

Impact of a diabetes disease management program on guideline-adherent care, hospitalization risk and health care costs: a propensity score matching study using real-world data

OBJECTIVE

To evaluate the impact of a DMP for patients with diabetes mellitus in a Swiss primary care setting.

METHODS

In a prospective observational study, we compared diabetes patients in a DMP (intervention group; N = 538) with diabetes patients receiving usual care (control group; N = 5050) using propensity score matching with entropy balancing. Using a difference-in-difference (DiD) approach, we compared changes in outcomes from baseline (2017) to 1-year (2017/18) and to 2-year follow-up (2017/19). Outcomes included four measures for guideline-adherent diabetes care, hospitalization risk, and health care costs.

RESULTS

We identified a positive impact of the DMP on the share of patients fulfilling all measures for guideline-adherent care [DiD 2017/18: 7.2 percentage-points, p < 0.01; 2017/19: 8.4 percentage-points, p < 0.001]. The hospitalization risk was lower in the intervention group in both years, but only statistically significant in the 1-year follow-up [DiD 2017/18: - 5.7 percentage-points, p < 0.05; 2017/19: - 3.9 percentage points, n.s.]. The increase in health care costs was smaller in the intervention than in the control group [DiD 2017/18: CHF - 852; 2017/19: CHF - 909], but this effect was not statistically significant.

CONCLUSION

The DMP under evaluation seems to exert a positive impact on the quality of diabetes care, reflected in the increase in the measures for guideline-adherent care and in a reduction of the hospitalization risk in the intervention group. It also might reduce health care costs, but only a longer follow-up will show whether the observed effect persists over time.

Impact of a multicomponent healthcare intervention on glycaemic control in subjects with poorly controlled type 2 diabetes: The INTEGRA study

AIM

To evaluate whether a specially designed multicomponent healthcare intervention improves glycaemic control in subjects with poorly controlled type 2 diabetes.

MATERIALS AND METHODS

A cluster, non-randomized, controlled, pragmatic trial in subjects from 11 primary care centres with type 2 diabetes and HbA1c of more than 9% (> 75 mmol/mol) was conducted. The intervention (N = 225 subjects) was professional and patient-centred, including a dedicated monographic visit that encouraged therapeutic intensification by physicians. The sham control (N = 181) was identical to that of the intervention group except that the dedicated visit was omitted. The primary outcome was to compare the reductions in HbA1c values between the groups at 12 months of follow-up.

RESULTS

The mean age at baseline was 59.5 years, mean diabetes duration was 10.7 years and mean HbA1c was 10.3% (89.0 mmol/mol). Patients in the intervention arm achieved significantly greater HbA1c reduction than those in the sham control group at 12 months (mean difference -0.62%, 95% CI = -0.2%, -1.04%; P = .002). A larger percentage of intervention participants achieved an HbA1c of less than 8% (44.8% vs. 25.5%; P = .003) and were more frequently treated with more than three antidiabetic therapies (14.4% vs. 3.5%; P = .0008). Intervention was the only variable associated with higher odds of HbA1c less than 8% (odds ratio = 2.52; 95% CI = 1.54-4.12; P < .001).

CONCLUSIONS

A multicomponent intervention including a dedicated visit oriented at reducing therapeutic inertia by primary care physicians can improve glycaemic control in poorly controlled patients with type 2 diabetes.

Upstream comprehensive management of individuals with diabetes with multimorbidity and frailty to act against amputation

This manuscript constitutes a commentary on: "Retrospective cohort study of long-term outcomes and prognostic factors for survival after lower extremity amputation in patients with diabetes" by Vuorlaakso et al. (2023). We aim to contribute to the reflection of their findings to support the comprehensive management of vulnerable individuals with multimorbidity and/frailty for limb preservation. There is an urgent need to understand the effects of frailty on overall survival after amputation, survival without major amputation, and the effect modification with multimorbidity.

Scale-up of a chronic care model-based programme for type 2 diabetes in Belgium: a mixed-methods study

BACKGROUND

Type 2 diabetes (T2D) is an increasingly dominant disease. Interventions are more effective when carried out by a prepared and proactive team within an organised system - the integrated care (IC) model. The Chronic Care Model (CCM) provides guidance for its implementation, but scale-up of IC is challenging, and this hampers outcomes for T2D care. In this paper, we used the CCM to investigate the current implementation of IC in primary care in Flanders (Belgium) and its variability in different practice types.

METHODS

Belgium contains three different primary-care practice types: monodisciplinary fee-for-service practices, multidisciplinary fee-for-service practices and multidisciplinary capitation-based practices. Disproportional sampling was used to select a maximum of 10 practices for each type in three Flemish regions, leading to a total of 66 practices. The study employed a mixed methods design whereby the Assessment of Chronic Illness Care (ACIC) was complemented with interviews with general practitioners, nurses and dieticians linked to the 66 practices.

RESULTS

The ACIC scores of the fee-for-service practices - containing 97% of Belgian patients - only corresponded to basic support for chronic illness care for T2D. Multidisciplinary and capitation-based practices scored considerably higher than traditional monodisciplinary fee-for-service practices. The region had no significant impact on the ACIC scores. Having a nurse, being a capitation practice and having a secretary had a significant effect in the regression analysis, which explained 75% of the variance in ACIC scores. Better-performing practices were successful due to clear role-defining, task delegation to the nurse, coordination, structured use of the electronic medical record, planning of consultations and integration of self-management support, and behaviour-change intervention (internally or using community initiatives). The longer nurses work in primary care practices, the higher the chance that they perform more advanced tasks.

CONCLUSIONS

Besides the presence of a nurse or secretary, also working multidisciplinary under one roof and a capitation-based financing system are important features of a system wherein IC for T2D can be scaled-up successfully. Belgian policymakers should rethink the role of paramedics in primary care and make the financing system more integrated. As the scale-up of the IC varied highly in different contexts, uniform roll-out across a health system containing multiple types of practices may not be successful.

Effectiveness of the chronic care model for adults with type 2 diabetes in primary care: a systematic review and meta-analysis

BACKGROUND

Mixed evidence exists regarding the effectiveness of the Chronic Care Model (CCM) with patient outcomes. The aim of this review is to examine the effectiveness of CCM interventions on hemoglobin A1c (HbA1c), systolic BP (SBP), diastolic BP (DBP), LDL cholesterol and body mass index (BMI) among primary care adults with type 2 diabetes.

METHODS

PubMed, Embase, CINAHL, Cochrane Central Registry of Controlled Trials, Scopus and Web of Science were searched from January 1990 to June 2021 for randomized controlled trials (RCTs) comparing CCM interventions against usual care among adults with type 2 diabetes mellitus in primary care with HbA1c, SBP, DBP, LDL cholesterol and BMI as outcomes. An abbreviated search was performed from 2021 to April 2022. This study followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines for data extraction and Cochrane risk of bias assessment. Two reviewers independently extracted the data. Meta-analysis was performed using Review Manager software. Heterogeneity was evaluated using χ2 and I2 test statistics. Overall effects were evaluated using Z statistic.

RESULTS

A total of 17 studies involving 16485 patients were identified. Most studies had low risks of bias. Meta-analysis of all 17 studies revealed that CCM interventions significantly decreased HbA1c levels compared to usual care, with a mean difference (MD) of -0.21%, 95% CI -0.30, -0.13; Z = 5.07, p<0.00001. Larger effects were experienced among adults with baseline HbA1c ≥8% (MD -0.36%, 95% CI -0.51, -0.21; Z = 5.05, p<0.00001) and when four or more CCM elements were present in the interventions (MD -0.25%, 95% CI -0.35, -0.15; Z = 4.85, p<0.00001). Interventions with CCM decreased SBP (MD -2.93 mmHg, 95% CI -4.46, -1.40, Z = 3.75, p=0.0002) and DBP (MD -1.35 mmHg, 95% CI -2.05, -0.65, Z = 3.79, p=0.0002) compared to usual care but there was no impact on LDL cholesterol levels or BMI.

CONCLUSIONS

CCM interventions, compared to usual care, improve glycaemic control among adults with type 2 diabetes in primary care, with greater reductions when the mean baseline HbA1c is ≥8% and with interventions containing four or more CCM elements.

Disease Management Program in patients with type 2 diabetes mellitus, long-term results of the early and established program cohort: A population-based retrospective cohort study

BACKGROUND

The aim of this study was to evaluate the long-term follow up of the early and the effectiveness of the established program of the Austrian Disease Management Program (DMP) 'Therapie aktiv-Diabetes im Griff' for patients with type 2 diabetes mellitus concerning mortality, major macrovascular complications, costs and process quality of care parameters.

METHODS

We conducted a propensity score matched cohort study based on routine health insurance data for type 2 diabetic patients. The observational period from the matched early program cohort starts from January 1, 2009 to December 31, 2017 and includes 7181 DMP participants and 21543 non-participants. In the established matched program cohort, 3087 DMP participants and 9261 non-participants were observed within January 1, 2014 to December 31, 2017.

RESULTS

In the early program cohort, 22.1% of the patients in the DMP-group and 29.7% in the control-group died after 8 years follow-up (HR = 0.70; 95% CI: 0.66-0.73). A difference of € 1070 (95% bootstrap-T interval: € 723 - € 1412) in mean total costs per year was observed. In the established program cohort, 10.4% DMP participants died 4 years after enrollment, whereas in the control-group 11.9% of the patients died (HR = 0.88, 95% CI: 0.78-0.99). Healthcare utilization is higher in the DMP-group (75%-96%) compared to the control-group (63%-90%).

CONCLUSIONS

The 8-year long-term follow up of the DMP program showed a relevant improvement of survival and healthcare costs of patients with type 2 diabetes. The established program cohort had improved survival and quality of care. Our findings indicate that the DMP "Therapie aktiv" provides a long-term advantage for type 2 diabetes patients.

Effectiveness of (Active) Lifestyle Interventions in People With a Lower Limb Amputation: A Systematic Review

Objective

To explore the effectiveness of (active) lifestyle interventions for the health of people with a lower limb amputation in order to offer effective interventions during rehabilitation that may improve physical and psychosocial functioning of people with lower limb amputation.

Data Sources

PubMed, CINAHL and Embase were searched from inception to February 2021.

Study Selection

Inclusion criteria were (1) (quasi-)randomized controlled trial; (2) minimum of 10 participants with a lower limb amputation; (3) lifestyle intervention focusing on physical activity, smoking habits, alcohol use, nutrition, and/or stress management; (4) focus on health outcomes; (5) participants older than 18 years; (6) studies in Dutch, German, or English; and (7) primary research. Title, abstract, and full-text screening and quality assessment were performed by 2 independent assessors.

Data Extraction

Of 2460 studies identified, 13 studies were included in this review. Two studies were of moderate methodological quality, 2 studies were of medium quality, and 9 studies were of poor quality.

Data Synthesis

Lifestyle interventions in the included studies focused on physical activity and stress management. These interventions seemed effective for improving physical fitness, walking capacity, changes in body mass, quality of life, and intensity of physical activity.

Conclusion

Lifestyle interventions focusing on physical activity and stress management seem effective for improving physical and psychosocial functioning of people with a lower limb amputation. However, the findings should be interpreted with caution given the limited methodological quality of the included studies. Future research should evaluate the effectiveness of interventions on nutrition, smoking habits, and alcohol use and the effectiveness of combined interventions in people with a lower limb amputation.

Primary care service utilisation and outcomes in type 2 diabetes: a longitudinal cohort analysis

OBJECTIVES

To describe primary care utilisation patterns among adults with type 2 diabetes and to quantify the association between utilisation and long-term health outcomes.

DESIGN

Retrospective cohort study.

SETTING

168 primary care practices in Southern England within the Electronic Care and Health Information Analytics database between 2013 and 2020.

PARTICIPANTS

110 240 adults with Quality and Outcomes Framework read code of type 2 diabetes diagnosis; age greater than 18 years; linked and continuous records available from April 2013 until April 2020 (or death). PRIMARY AND SECONDARY OUTCOME MEASURES: (1) Rates of service utilisation (total number of primary care contacts per quarter) across the study period; (2) participant characteristics associated with higher and lower rates of service utilisation; and (3) associations between service utilisation and (A) cardiovascular disease (CVD events) and (B) all-cause mortality.

RESULTS

Mean (SD) number of primary care attendances per quarter in the cohort of 110 240 went from 2.49 (2.01) in 2013 to 2.78 (2.06) in 2020. Patients in the highest usage tertile were more likely to be female, older, more frail, white, from the least deprived quintile and to have five or more comorbidities. In adjusted models, higher rates of service utilisation (per consultation) were associated with higher rates of CVD events (OR 1.0058; 95% CI 1.0053 to 1.0062; p<0.001) and mortality (OR 1.0057; 95% CI 1.0051 to 1.0064; p<0.001).

CONCLUSIONS

People with type 2 diabetes are using primary care services more frequently, but increased volume of clinical care does not correlate with better outcomes, although this finding may be driven by more unwell patients contacting services more frequently. Further research on the nature and content of contacts is required to understand how to tailor services to deliver effective care to those at greatest risk of complications.

Management of chronic kidney disease in type 2 diabetes: screening, diagnosis and treatment goals, and recommendations

Patients with chronic kidney disease (CKD) and type 2 diabetes (T2D) are at high risk of CKD progression and cardiovascular (CV) disease. Prevalence of CKD in patients with T2D is currently around 40% and continues to grow. The increasing number of people with CKD and T2D will ultimately have a significant impact upon health resource use and costs of care for people with T2D. Management of CKD in patients with T2D aims to preserve kidney function to reduce the risk of end-stage kidney disease, CV events, and mortality. Evidence-based recommendations for the treatment of patients with CKD and T2D are provided by several international and national organizations and recommend several lifestyle and pharmacological approaches to help prevent or delay the progression of CKD in patients with T2D. Guidelines include regular screening of patients with T2D for CKD using spot urine albumin-to-creatinine ratio (UACR) and estimated glomerular filtration rate (at least annually and at least twice a year if UACR >300 mg/g). Additionally, assessment of vascular complications, together with interventions designed to improve glycemic control and lipid levels, maintain healthy body weight, and optimize blood pressure should be performed. Medications shown to slow progression of CKD include renin-angiotensin system inhibitors, sodium-glucose cotransporter-2 inhibitors, glucagon-like peptide 1 receptor agonists, and, more recently, selective, non-steroidal mineralocorticoid receptor antagonists. This review highlights the ongoing challenges facing primary care providers in the management of CKD in patients with T2D including the consideration of comorbidities, adoption of new treatment options, and implementation of individualized care. Achieving consensus for optimal treatment of this disease is critical in providing consistent and appropriate care for all patients. Strategies to improve outcomes should also include use of clear referral criteria, use of a multi-disciplinary approach, and patient education.

Prediabetes and cardiovascular complications study: Highlights on gestational diabetes, self-management and primary health care

International collaboration on the prediabetes and cardiovascular complications study started in 2013. In 2017, a reflection was reported. Incompleteness of documentation and screening of antenatal cases for gestational diabetes mellitus (GDM) was concerning. Hence, further observations have been made that warrant an update. The objective of this review is to highlight gaps between clinical knowledge and practice in GDM, diabetes self-management and primary health care (PHC) for rural dwellers. We followed a descriptive field notes method. Antenatal records of patients screened for GDM with incomplete documentation were examined to determine incompleteness of data in those that also met the criteria for GDM risk assessment. Experiences on development of a diabetes register and education and notes on behavioural change wheel were also reviewed. Other data included cross-sectional evaluation of activities of daily living at two private hospitals. Up to 29% had high GDM risk factors, which fulfilled selection criteria for laboratory screening. Demographic data was complete in all women; however, incomplete documentation was observed with as much as 98% of basic data. High levels of physical activity were found in the population, and health lectures proved effective in food choices. The workforce need for diabetes care seems underestimated, but this may be better understood with reactivation of PHC services. The observations highlight behavioural change wheel issues on GDM and PHC services that need concerted focus. Two proposals are to advance the use of a ‘risk assessment and screening sheet’ for GDM screening and enlightenment of stakeholders on the central hub role of PHC in diabetes management.

The cost-saving effect of continuity of care (COC): an analysis of institutional COC on diabetic treatment costs using panel 2SLS regressions

BACKGROUND

The high costs of chronic conditions call for new treatment approaches that reduce costs while ensuring desirable health outcomes. There has been a growing transformation of care delivery models from conventional referral systems to integrated care models. This study seeks to evaluate the cost-saving impact of integrated care delivery model under pay-for-performance (P4P) scheme with continuity of care at institution level (ICOC).

METHODS

We analyzed the Taiwan National Health Insurance claim data of 21,725 diabetic patients who visited clinics and/or hospitals at least four times a year for 8 years. Using average local provider P4P participation rate (for each accreditation level) as an instrumental variable in two-stage least squares (2SLS) regressions, we have estimated consistent estimates of the ICOC elasticities for all-cause inpatient and outpatient costs.

RESULTS

Our results show that ICOC significantly reduced inpatient costs but increased outpatient costs with the elasticity for treatment costs of -11.6 and 1.03, respectively. The decrease in inpatient costs offset the increase in outpatient costs and the resulting total cost saving showed significant association with ICOC. The saving effect of ICOC is especially robust among patients who used clinics as their principal source of care.

CONCLUSIONS

Institutional continuity of care has a substantial impact on the treatment costs of diabetes patients. In the context where inpatient care costs are significantly higher than that of the outpatient care, ICOC would lead to a meaningful cost-saving effect. For new diabetes patients, care by clinics demonstrated the strongest saving effect.

Integrated disease management interventions for patients with chronic obstructive pulmonary disease

BACKGROUND

People with chronic obstructive pulmonary disease (COPD) show considerable variation in symptoms, limitations, and well-being; this often complicates medical care. A multi-disciplinary and multi-component programme that addresses different elements of care could improve quality of life (QoL) and exercise tolerance, while reducing the number of exacerbations.

OBJECTIVES

To compare the effectiveness of integrated disease management (IDM) programmes versus usual care for people with chronic obstructive pulmonary disease (COPD) in terms of health-related quality of life (QoL), exercise tolerance, and exacerbation-related outcomes.

SEARCH METHODS

We searched the Cochrane Airways Group Register of Trials, CENTRAL, MEDLINE, Embase, and CINAHL for potentially eligible studies. Searches were current as of September 2020.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that compared IDM programmes for COPD versus usual care were included. Interventions consisted of multi-disciplinary (two or more healthcare providers) and multi-treatment (two or more components) IDM programmes of at least three months' duration.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. If required, we contacted study authors to request additional data. We performed meta-analyses using random-effects modelling. We carried out sensitivity analyses for the quality of included studies and performed subgroup analyses based on setting, study design, dominant intervention components, and region.

MAIN RESULTS

Along with 26 studies included in the 2013 Cochrane Review, we added 26 studies for this update, resulting in 52 studies involving 21,086 participants for inclusion in the meta-analysis. Follow-up periods ranged between 3 and 48 months and were classified as short-term (up to 6 months), medium-term (6 to 15 months), and long-term (longer than 15 months) follow-up. Studies were conducted in 19 different countries. The mean age of included participants was 67 years, and 66% were male. Participants were treated in all types of healthcare settings, including primary (n =15), secondary (n = 22), and tertiary care (n = 5), and combined primary and secondary care (n = 10). Overall, the level of certainty of evidence was moderate to high. We found that IDM probably improves health-related QoL as measured by St. George's Respiratory Questionnaire (SGRQ) total score at medium-term follow-up (mean difference (MD) -3.89, 95% confidence interval (CI) -6.16 to -1.63; 18 RCTs, 4321 participants; moderate-certainty evidence). A comparable effect was observed at short-term follow-up (MD -3.78, 95% CI -6.29 to -1.28; 16 RCTs, 1788 participants). However, the common effect did not exceed the minimum clinically important difference (MCID) of 4 points. There was no significant difference between IDM and control for long-term follow-up and for generic QoL. IDM probably also leads to a large improvement in maximum and functional exercise capacity, as measured by six-minute walking distance (6MWD), at medium-term follow-up (MD 44.69, 95% CI 24.01 to 65.37; 13 studies, 2071 participants; moderate-certainty evidence). The effect exceeded the MCID of 35 metres and was even greater at short-term (MD 52.26, 95% CI 32.39 to 72.74; 17 RCTs, 1390 participants) and long-term (MD 48.83, 95% CI 16.37 to 80.49; 6 RCTs, 7288 participants) follow-up. The number of participants with respiratory-related admissions was reduced from 324 per 1000 participants in the control group to 235 per 1000 participants in the IDM group (odds ratio (OR) 0.64, 95% CI 0.50 to 0.81; 15 RCTs, median follow-up 12 months, 4207 participants; high-certainty evidence). Likewise, IDM probably results in a reduction in emergency department (ED) visits (OR 0.69, 95%CI 0.50 to 0.93; 9 RCTs, median follow-up 12 months, 8791 participants; moderate-certainty evidence), a slight reduction in all-cause hospital admissions (OR 0.75, 95%CI 0.57 to 0.98; 10 RCTs, median follow-up 12 months, 9030 participants; moderate-certainty evidence), and fewer hospital days per person admitted (MD -2.27, 95% CI -3.98 to -0.56; 14 RCTs, median follow-up 12 months, 3563 participants; moderate-certainty evidence). Statistically significant improvement was noted on the Medical Research Council (MRC) Dyspnoea Scale at short- and medium-term follow-up but not at long-term follow-up. No differences between groups were reported for mortality, courses of antibiotics/prednisolone, dyspnoea, and depression and anxiety scores. Subgroup analysis of dominant intervention components and regions of study suggested context- and intervention-specific effects. However, some subgroup analyses were marked by considerable heterogeneity or included few studies. These results should therefore be interpreted with caution.

AUTHORS' CONCLUSIONS

This review shows that IDM probably results in improvement in disease-specific QoL, exercise capacity, hospital admissions, and hospital days per person. Future research should evaluate which combination of IDM components and which intervention duration are most effective for IDM programmes, and should consider contextual determinants of implementation and treatment effect, including process-related outcomes, long-term follow-up, and cost-effectiveness analyses.

Update on Approaches to Improve Delivery and Quality of Care for People with Diabetes

To translate improvements in diabetes management into improved outcomes, it is essential to improve care delivery. To help guide clinicians and health organizations in their efforts to achieve these improvements, this article briefly describes key components underpinning effective diabetes care and six categories of innovations in approaches to improve diabetes care delivery: (1) team-based clinical care; (2) cross-specialty collaboration/integration; (3) virtual clinical care/telehealth; (4) use of community health workers (CHWs) and trained peers to provide pro-active self-management support; (5) incorporating screening for and addressing social determinants of health into clinical practice; and (6) cross-sectoral clinic/community partnerships.

Chronic care model in the diabetes pay-for-performance program in Taiwan: Benefits, challenges and future directions

In this review, we discuss the chronic care model (CCM) in relation to the diabetes pay-for-performance (P4P) program in Taiwan. We first introduce the 6 components of the CCM and provide a detailed description of each of the activities in the P4P program implemented in Taiwan, mapping them onto the 6 components of the CCM. For each CCM component, the following three topics are described: the definition of the CCM component, the general activities implemented related to this component, and practical and empirical practices based on hospital or local government cases. We then conclude by describing the possible successful features of this P4P program and its challenges and future directions. We conclude that the successful characteristics of this P4P program in Taiwan include its focus on extrinsic and intrinsic incentives (i.e., shared care network), physician-led P4P and the implementation of activities based on the CCM components. However, due to the low rate of P4P program coverage, approximately 50% of patients with diabetes cannot enjoy the benefits of CCM-related activities or receive necessary examinations. In addition, most of these CCM-related activities are not allotted an adequate amount of incentives, and these activities are mainly implemented in hospitals, which compared with primary care providers, are unable to execute these activities flexibly. All of these issues, as well as insufficient implementation of the e-CCM model, could hinder the advanced improvement of diabetes care in Taiwan.

Type 2 diabetes: patient assessment of chronic illness care

Objective

We tried to assess perception of chronic illness care in people with type 2 diabetes and to determine whether demographic variables, self-care behavior, as well as affective variables were related with perception of chronic illness care.

Methods

We conducted a secondary analysis of the previously published cross-sectional study in 441 Iranian people with type 2 diabetes. Chronic illness care was assessed with the validated tool of patient assessment of chronic illness care (PACIC). Different aspects of care according to the chronic care model are measured on a scale of 1-5, with 5 being highest perception of care. The association between perception of chronic illness care and measured variables were tested using spearman correlation test as well as univariate and multiple linear regression analysis.

Results

Finally, 380 filled out the PACIC questionnaire, completely (53.4% female, mean age: 54.73 ± 8.0 years, mean PACIC score: 2.52 ± 0.87). In spearman correlation test, considering PACIC score as the dependent variable, chronic illness care was inversely associated with level of education and distress, whereas, insulin treatment, wellbeing, family-social support and self-management were positively associated with chronic care (All p value<0.05). In the multiple linear regression analysis, family-social support was positively related to chronic care while level of education, marital status, diabetes-related distress, and high density lipoprotein had significant negative relationship with PACIC score (All p value<0.05).

Conclusions

Family-social support, level of education, marital status, and diabetes-related distress are the major determinants of patient experience of chronic illness care in people with type 2 diabetes.

Population Health Management in Diabetes Care: Combining Clinical Audit, Risk Stratification, and Multidisciplinary Virtual Clinics in a Community Setting to Improve Diabetes Care in a Geographically Defined Population. An Integrated Diabetes Care Pilot in the North East Locality, Oxfordshire, UK

BACKGROUND

Disparities in diabetes care are prevalent, with significant inequalities observed in access to, and outcomes of, healthcare. A population health approach offers a solution to improve the quality of care for all with systematic ways of assessing whole population requirements and treating and monitoring sub-groups in need of additional attention.

DESCRIPTION OF THE CARE PRACTICE

Collaborative working between primary, secondary and community care was introduced in seven primary care practices in one locality in England, UK, caring for 3560 patients with diabetes and sharing the same community and secondary specialist diabetes care providers. Three elements of the intervention included 1) clinical audit, 2) risk stratification, and 3) the multi-disciplinary virtual clinics in the community.

METHODS

This paper evaluates the acceptability, feasibility and short-term impact on primary care of implementing a population approach intervention using direct observations of the clinics and surveys of participating clinicians.

RESULTS AND DISCUSSION

Eighteen virtual clinics across seven teams took place over six months between March and July 2017 with organisation, resources, policies, education and approximately 150 individuals discussed. The feedback from primary care was positive with growing knowledge and confidence managing people with complex diabetes in primary care.

CONCLUSION

Taking a population health approach helped to identify groups of people in need of additional diabetes care and deliver a collaborative health intervention across traditional organisational boundaries.

Lifestyle Risk Factors for Type 2 Diabetes Mellitus and National Diabetes Care Systems in European Countries

Background. Diabetes is increasing by 3.09% per year in males and 1.92% in females. Lifestyle risk factors are related to diabetes. The aim of this work is to highlight within EU-28 countries the distribution percentages of some lifestyle risk factors and some components of diabetes health care. Methods. A literature search was conducted to highlight the presence of diabetes registries, which are fundamental tools for disease surveillance and health planning; the presence of a national diabetes plan (NDP); the care setting; and methods used for reimbursement of drugs, devices, and coverage of any comorbidities associated with diabetes. A multiple correspondence analysis (MCA) was carried out to evaluate the possible associations between the variables considered. Results. The highest percentages of diabetes (>10%) are registered in Bulgaria, Malta, and Hungary. Concerning the prevalence of overweight, no European country shows overall percentages of less than 50%. Regarding obesity, 57% of countries show prevalence rates of 25%. The record for physical inactivity belongs to Malta, with 45% of individuals being inactive. The percentage of physical inactivity for females is higher than for males across Europe. In total, 57% of the countries have an insurance-based health system, while 12 countries have public national health systems. Further, 57% of countries have an NDP, while 42% of the EU countries have established a prevalence register for diabetes. Conclusions. Prevalence rates for type 2 DM in the range of 8–9% are noted in 50% of EU-28 countries. In total, 21 out of EU countries show a high prevalence rate for overweight, while 7% of EU-28 countries have an obesity prevalence rate of 25%. Diabetes treatment is entrusted to general practitioners in most countries. The results of this work highlight the differences between countries, but also between genders.

Effects of an Electronic Software "Prompt" With Health Care Professional Training on Cardiovascular and Renal Complications in a Multiethnic Population With Type 2 Diabetes and Microalbuminuria (the GP-Prompt Study): Results of a Pragmatic Cluster-Randomized Trial

OBJECTIVE

Tight, targeted control of modifiable cardiovascular risk factors can reduce cardiovascular complications and mortality in individuals with type 2 diabetes mellitus (T2DM) and microalbuminuria. The effects of using an electronic "prompt" with a treatment algorithm to support a treat-to-target approach has not been tested in primary care.

RESEARCH DESIGN AND METHODS

A multicenter, cluster-randomized trial was conducted among primary care practices across Leicestershire, U.K. The primary outcome was the proportion of individuals achieving systolic and diastolic blood pressure (<130 and <80 mmHg, respectively) and total cholesterol (<3.5 mmol/L) targets at 24 months. Secondary outcomes included proportion of individuals with HbA_1c <58 mmol/mol (<7.5%), changes in prescribing, change in the albumin-to-creatinine ratio, major adverse cardiovascular events, cardiovascular mortality, and coding accuracy.

RESULTS

A total of 2,721 individuals from 22 practices, mean age 63 years, 41% female, and 62% from black and minority ethnic groups completed 2 years of follow-up. There were no significant differences in the proportion of individuals achieving the composite primary outcome, although the proportion of individuals achieving the prespecified outcome of total cholesterol <4.0 mmol/L (odds ratio 1.24; 95% CI 1.05-1.47; P = 0.01) increased with intensive intervention compared with control. Coding for microalbuminuria increased relative to control (odds ratio 2.05; 95% CI 1.29-3.25; P < 0.01).

CONCLUSIONS

Greater improvements in composite cardiovascular risk factor control with this intervention compared with standard care were not achieved in this cohort of high-risk individuals with T2DM. However, improvements in lipid profile and coding can benefit patients with diabetes to alter the high risk of atherosclerotic cardiovascular events. Future studies should consider comprehensive strategies, including patient education and health care professional engagement, in the management of T2DM.

The Role of Physician and Practice Characteristics in the Quality of Diabetes Management in Primary Care: Systematic Review and Meta-analysis

BACKGROUND

Despite evidence-based guidelines, high-quality diabetes care is not always achieved. Identifying factors associated with the quality of management in primary care may inform service improvements, facilitating the tailoring of quality improvement interventions to practice needs and resources.

METHODS

We searched MEDLINE, EMBASE, CINAHL and Web of Science from January 1990 to March 2019. Eligible studies were cohort studies, cross-sectional studies and randomised controlled trials (baseline data) conducted among adults with diabetes, which examined the relationship between any physician and/or practice factors and any objective measure(s) of quality. Studies which examined patient factors only were ineligible. Where possible, data were pooled using random-effects meta-analysis.

RESULTS

In total, 82 studies were included. The range of individual quality measures and the construction of composite measures varied considerably. Female physicians compared with males ((odds ratio (OR) = 1.07, 95% CI: 1.04, 1.10), 8 studies), physicians with higher diabetes volume compared with lower volume (OR = 1.24, 95% CI: 1.05-1.47, 4 studies) and practices with Electronic Health Records (EHR) versus practices without (OR = 1.43, 95% CI: 1.11-1.84, 4 studies) were associated with a higher quality of care. There was no association between physician experience, practice location and type of practice and quality. Based on the narrative synthesis, increasing physician age and higher practice socio-economic deprivation may be associated with lower quality of care.

DISCUSSION

Identification of physician- and practice-level factors associated with the quality of care (female gender, younger age, physician-level diabetes volume, practice deprivation and EHR use) may explain differences across practices and physicians, provide potential targets for quality improvement interventions and indicate which practices need specific supports to deliver improvements in diabetes care.

The Manage Care Model - Developing an Evidence-Based and Expert-Driven Chronic Care Management Model for Patients with Diabetes

BACKGROUND

Most current care models are disease- or symptom-focused and mostly do not account for the individual needs of patients with chronic diseases. The aim of this study was to develop an innovative, evidence-based and expert-based practice model for the management of patients with type 2 diabetes mellitus.

METHOD

An iterative approach was used combining systematic literature search with qualitative methods, including a standardised survey of experts in chronic care (n = 92), an expert workshop of professionals (n = 22) and a multilingual online survey (n = 659). Using three consensus meetings involving researchers, policy makers and experts in chronic care, a limited number of core components and care recommendations was set up to develop a new chronic care model.

RESULTS

The developed 'MANAGE CARE MODEL' includes aspects of the health and social care system, resources derived from the living environment, aspects of health promotion and prevention, as well as an expanded understanding of improved outcomes as an integral part of chronic care.

CONCLUSION

The MANAGE CARE MODEL provides guidance for the development and implementation of chronic care programs, regional networks and national strategies. Future research is needed to validate the model as an instrument of regional chronic care management.

The EMPOWER-SUSTAIN e-Health Intervention to improve patient activation and self-management behaviours among individuals with Metabolic Syndrome in primary care: study protocol for a pilot randomised controlled trial

Background

Epidemiological studies conducted in various parts of the world have clearly demonstrated that metabolic syndrome (MetS) is an increasing global health problem, not only in Western societies but also in Asian populations. Web-based and mobile phone-based self-management applications have been proven to be effective in improving self-management behaviour of patients with MetS components (i.e., diabetes or hypertension). However, evidence is lacking in terms of their effectiveness specifically for patients with MetS. The aim of this pilot study is to evaluate the feasibility and potential effectiveness of the EMPOWER-SUSTAIN Self-Management e-Health Intervention in improving activation and self-management behaviours among patients with MetS. This paper presents the study protocol.

Methods

A pilot randomised controlled trial will be conducted in a university primary care clinic. A total of 232 patients aged 18–60 years with MetS will be recruited; 116 will be randomised to receive the EMPOWER-SUSTAIN intervention for 6 months, and another 116 patients will continue with usual care. The EMPOWER-SUSTAIN intervention is a multifaceted chronic disease management strategy based on the Chronic Care Model and persuasive technology theory. It consists of training primary care physicians, nurses and patients to use the EMPOWER-SUSTAIN web-based self-management mobile app, strengthening the patient–physician relationship and reinforcing the use of relevant clinical practice guidelines to guide management and prescribing. The primary outcome is the mean change in patient activation score using the Patient Activation Measure short form Malay version (PAM-13-M) questionnaire. The secondary outcomes include the changes in waist circumference, body mass index, blood pressure, patient physical activity level, eating behaviour, perception of chronic illness care, satisfaction with patient–physician interaction, and perceived absolute 10-year cardiovascular disease risk. Feasibility of implementing the intervention will be evaluated. This includes acceptability of the intervention, estimating the likely rate of participant recruitment and retention, appropriateness of the outcome measures, calculation of sample size, and the intervention’s potential effectiveness.

Conclusion

To our knowledge, this is the first study in Malaysia that aims to determine the feasibility of a multifaceted e-health intervention, as well as to indicate more useful aspects of this intervention for further exploration in a larger trial.

Mapping the Evidence on the Effectiveness of Telemedicine Interventions in Diabetes, Dyslipidemia, and Hypertension: An Umbrella Review of Systematic Reviews and Meta-Analyses

Background

Telemedicine is defined by three characteristics: (1) using information and communication technologies, (2) covering a geographical distance, and (3) involving professionals who deliver care directly to a patient or a group of patients. It is said to improve chronic care management and self-management in patients with chronic diseases. However, currently available guidelines for the care of patients with diabetes, hypertension, or dyslipidemia do not include evidence-based guidance on which components of telemedicine are most effective for which patient populations.

Objective

The primary aim of this study was to identify, synthesize, and critically appraise evidence on the effectiveness of telemedicine solutions and their components on clinical outcomes in patients with diabetes, hypertension, or dyslipidemia.

Methods

We conducted an umbrella review of high-level evidence, including systematic reviews and meta-analyses of randomized controlled trials. On the basis of predefined eligibility criteria, extensive automated and manual searches of the databases PubMed, EMBASE, and Cochrane Library were conducted. Two authors independently screened the studies, extracted data, and carried out the quality assessments. Extracted data were presented according to intervention components and patient characteristics using defined thresholds of clinical relevance. Overall certainty of outcomes was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool.

Results

Overall, 3564 references were identified, of which 46 records were included after applying eligibility criteria. The majority of included studies were published after 2015. Significant and clinically relevant reduction rates for glycated hemoglobin (HbA_1c; ≤−0.5%) were found in patients with diabetes. Higher reduction rates were found for recently diagnosed patients and those with higher baseline HbA_1c (>8%). Telemedicine was not found to have a significant and clinically meaningful impact on blood pressure. Only reviews or meta-analyses reporting lipid outcomes in patients with diabetes were found. GRADE assessment revealed that the overall quality of the evidence was low to very low.

Conclusions

The results of this umbrella review indicate that telemedicine has the potential to improve clinical outcomes in patients with diabetes. Although subgroup-specific effectiveness rates favoring certain intervention and population characteristics were found, the low GRADE ratings indicate that evidence can be considered as limited. Future updates of clinical care and practice guidelines should carefully assess the methodological quality of studies and the overall certainty of subgroup-specific outcomes before recommending telemedicine interventions for certain patient populations.

The Microalbuminuria Education Medication and Optimisation (MEMO) study: 4 years follow-up of multifactorial intervention in high-risk individuals with type 2 diabetes

AIMS

The Microalbuminuria Education Medication and Optimisation (MEMO) study, revealed improved cardiovascular risk and glycaemic control with 18 months of intensive multifactorial intervention in high-risk people with type 2 diabetes, without any increase in severe hypoglycaemia. Our aim was to assess longer-term outcomes at 4-year follow-up in these participants.

METHODS

Some 189 individuals with type 2 diabetes and microalbuminuria were recruited from a multi-ethnic population in Leicestershire, UK. The intervention group (n = 95) received multifactorial intervention with self-management education, and the control group (n = 94) received usual care. The primary outcome was change in HbA_1c , and secondary outcomes were blood pressure (BP), cholesterol, microalbuminuria, estimated GFR, cardiovascular risk scores and major adverse cardiovascular events.

RESULTS

Some 130 participants (68.7%), mean (sd) age 60.8 (10.4) years, duration of diabetes 11.5 (9.7) years, completed 4 years of follow-up. Mean change [95% confidence intervals (CI)] in HbA_1c over 4 years was greater with intensive intervention compared with control (-3 mmol/mol, 95% CI -4.95,-1.11; -0.4%, 95% CI -0.67,-0.15; P = 0.002). Significant improvements over the 4 years were also seen in systolic BP (-7.3 mmHg, 95% CI -11.1, -3.5; P < 0.001), diastolic BP (-2.9 mmHg, 95% CI -5.4, -0.3; P = 0.026), cholesterol (-0.3 mmol/l, 95% CI -0.52,-0.12; P = 0.002), and 10-year coronary heart disease (-5.3, 95% CI -8.2,-2.3; P < 0.001) and stroke risk (-4.4, 95% CI -7.5, -1.3; P < 0.001).

CONCLUSION

Multifactorial intervention with structured diabetes self-management education compared with usual diabetes care has benefits for cardio-metabolic risk factor profile. There was no increase in severe hypoglycaemia and cardiovascular mortality despite intensive glycaemic control, although the study was not powered to assess these outcomes.

Application of machine learning methodology to assess the performance of DIABETIMSS program for patients with type 2 diabetes in family medicine clinics in Mexico

Background

The study aimed to assess the performance of a multidisciplinary-team diabetes care program called DIABETIMSS on glycemic control of type 2 diabetes (T2D) patients, by using available observational patient data and machine-learning-based targeted learning methods.

Methods

We analyzed electronic health records and laboratory databases from the year 2012 to 2016 of T2D patients from six family medicine clinics (FMCs) delivering the DIABETIMSS program, and five FMCs providing routine care. All FMCs belong to the Mexican Institute of Social Security and are in Mexico City and the State of Mexico. The primary outcome was glycemic control. The study covariates included: patient sex, age, anthropometric data, history of glycemic control, diabetic complications and comorbidity. We measured the effects of DIABETIMSS program through 1) simple unadjusted mean differences; 2) adjusted via standard logistic regression and 3) adjusted via targeted machine learning. We treated the data as a serial cross-sectional study, conducted a standard principal components analysis to explore the distribution of covariates among clinics, and performed regression tree on data transformed to use the prediction model to identify patient sub-groups in whom the program was most successful. To explore the robustness of the machine learning approaches, we conducted a set of simulations and the sensitivity analysis with process-of-care indicators as possible confounders.

Results

The study included 78,894 T2D patients, from which 37,767patients received care through DIABETIMSS. The impact of DIABETIMSS ranged, among clinics, from 2 to 8% improvement in glycemic control, with an overall (pooled) estimate of 5% improvement. T2D patients with fewer complications have more significant benefit from DIABETIMSS than those with more complications. At the FMC’s delivering the conventional model the predicted impacts were like what was observed empirically in the DIABETIMSS clinics. The sensitivity analysis did not change the overall estimate average across clinics.

Conclusions

DIABETIMSS program had a small, but significant increase in glycemic control. The use of machine learning methods yields both population-level effects and pinpoints the sub-groups of patients the program benefits the most. These methods exploit the potential of routine observational patient data within complex healthcare systems to inform decision-makers.

Chronic disease management: Discussing the perspectives of general practitioners in Italy

The aim of this paper is to provide an overview of general practitioners’ perspectives across key criteria for effective chronic disease management. The study setting is the Tuscany Region in Italy that implemented the Chronic Care Model in 2010 with multidisciplinary team to assist chronic patients. We used the results of a web-based survey of general practitioners (N = 1136) conducted in 2015 to compare the experiences and satisfaction of general practitioners involved (group 1) and not involved (group 2) in the Chronic Care Model. The analysis included all general practitioners, and compared the two groups’ perspectives of the different core aspects of Chronic Care Model through conducting an ANOVA analysis and Bonferroni test. General practitioners involved in the Chronic Care Model are found to be more favourably disposed toward measurement and benchmarking, and more satisfied in terms of decision support system. Conversely, no significant differences were found in terms of collaboration with specialists, which remains weak and in terms of community collaboration and involvement. This study provides a detailed investigation of the implementation of Disease Management Programs, by considering the professional point of view.

Reprint of: Blood Sugar Regulation for Cardiovascular Health Promotion and Disease Prevention: JACC Health Promotion Series

The primary objective of this study was to analyze the most up-to-date evidence regarding whether and how blood sugar regulation influences cardiovascular health promotion and disease prevention by carrying out an umbrella review. Three separate, systematic literature searches identified 2,343 papers in total. Overall, 44 studies were included for data extraction and analysis. The included systematic reviews and meta-analyses published between January 1, 2016, and December 31, 2017, were of good to very good quality (median Overview Quality Assessment Questionnaire score = 17). Identified evidence suggests that cardiovascular disease (CVD) prevention services should consider regulation of blood glucose as a key target for intervention. Furthermore, the recommendations for effective intervention and service development/training described here for prevention of CVD should be adopted into evidence-based practice guidelines. Multidisciplinary teams should be formed to deliver multicomponent interventions in community-based settings. There may be substantial opportunities for integrating CVD and diabetes prevention services.

Long-term effectiveness of a type 2 diabetes comprehensive care program. The CAIPaDi model

AIMS

To evaluate the effectiveness of a comprehensive care program to achieve and maintain goals in patients with type 2 diabetes.

METHODS

The CAIPaDi program includes 9 interventions delivered in 7 h. It seeks to achieve metabolic goals, identify and resolve barriers that would make implementation difficult, and provide self-efficacy and empowerment to patients by identifying personal profiles to establish individualized strategies. The program consists of a 4 intervention visits (1, 2, 3, and 4 months) and two follow up visits (12 and 24 months). Outcomes are compared between every visit. Main outcome was the attainment of the USA National Committee for Quality Assurance treatment goals.

RESULTS

1104 patients completed the first 4 visits, 545 the 12 month evaluation, and 218 the 24 month evaluation. After the conclusion of the four monthly sessions, 80.6% had HbA1c <7%, 72.1% had BP <130/80 mmHg and 71.6% had LDL- cholesterol <100 mg/dl. After twelve months, the percentage of goals achieved were 65.9%, 67.7% and 43.3% respectively (p < 0.001). For the 2-year evaluation the percentages were 61.0%, 70.6%, and 40.8% respectively (p < 0.001). All patients had renal, eye, foot and dental evaluations. Empowerment and quality of life showed significant changes; anxiety and depression scores remained low at annual follow-ups.

CONCLUSIONS

The CAIPaDI program results in sustained improvement and maintenance of treatment goals.

The Berlin Declaration: A call to improve early actions related to type 2 diabetes. Why is primary care important?

Diabetes is epidemic worldwide and places a huge burden on healthcare systems. The majority of the cost of type 2 diabetes (T2D) is related to hospitalization and the management of complications, and these also have a negative impact on the individual's quality of life. The Berlin Declaration is a global call for early action for the identification of high risk individuals, prevention of T2D and the prevention of complications in those with T2D, through prevention, early detection, early control and early access to the right multidisciplinary interventions. This should empower people to take action to prevent T2D and its complications.

Incidence rates of dysvascular lower extremity amputation changes in Northern Netherlands: A comparison of three cohorts of 1991-1992, 2003-2004 and 2012-2013

Objective

To analyze the incidence rates of dysvascular major lower extremity amputations (LEA) in Northern Netherlands in 2012–2013 compared to previous cohorts in 1991–1992 and 2003–2004.

Design

Retrospective cohort study.

Participants

Adults (N = 343) with first ever dysvascular LEA at ankle disarticulation or more proximal levels. The median age (interquartile range) was 74.2 years (64.5–81.9), 64% were male and 55% had been diagnosed with diabetes mellitus (DM).

Main outcome measures

Crude and age-standardized incidence rates of major LEA per 100.000 person-years.

Results

Crude incidence rate (IR) of first ever major LEA in 2012–2013 was 9.9 per 100.000 person-years, while the age-standardized IR was 7.7 per 100.000 person-years. A Poisson regression analysis showed that amputation rates among men were 2.3 times higher compared to women (95%CI 1.9–2.6), while in 2012–2013 the population aged >63 years had decreased amputation rates compared to 1991–1992. In the DM population the crude IR decreased from 142.6 per 100.000 person-years in 2003–2004 to 89.2 per 100.000 person-years in 2012–2013 (p<0.001).

Conclusions

In 2012–2013 a decrease in age-standardized IR for the general population and a decrease in crude IR for the DM population were observed compared to cohorts from the previous two decades, despite considerable shifts in the age distribution of the Dutch population towards more elderly people and increased prevalence of DM. These findings might suggest that improved treatment of patients at risk of dysvascular amputations is associated with reduced incidence rates of major LEA at the population level.

Transfer from paediatric to adult care for young adults with Type 2 diabetes: the SEARCH for Diabetes in Youth Study

AIM

To describe factors associated with transfer from paediatric to adult care and poor glycaemic control among young adults with Type 2 diabetes, using the SEARCH for Diabetes in Youth study.

METHODS

Young adults with Type 2 diabetes were included if they had a baseline SEARCH visit while in paediatric care at < 18 years and ≥ 1 follow-up SEARCH visit thereafter at 18-25 years. At each visit, HbA1c , BMI, self-reported demographic and healthcare provider data were collected. Associations of demographic factors with transfer of care and poor glycaemic control (HbA1c ≥ 75 mmol/mol; 9.0%) were explored with multivariable logistic regression.

RESULTS

182 young adults with Type 2 diabetes (36% male, 75% minority, 87% with obesity) were included. Most (n = 102, 56%) reported transfer to adult care at follow-up; a substantial proportion (n = 28, 15%) reported no care and 29% did not transfer. Duration of diabetes [odds ratio (OR) 1.4, 95% confidence interval (95% CI) 1.1, 1.8] and age at diagnosis (OR 1.8, 95% CI 1.4, 2.4) predicted leaving paediatric care. Transfer to adult or no care was associated with a higher likelihood of poor glycaemic control at follow-up (adult: OR 4.5, 95% CI 1.8, 11.2; none: OR 4.6, 95% CI 1.4, 14.6), independent of sex, age, race/ethnicity or baseline HbA1c level.

CONCLUSIONS

Young adults with Type 2 diabetes exhibit worsening glycaemic control and loss to follow-up during the transfer from paediatric to adult care. Our study highlights the need for development of tailored clinical programmes and healthcare system policies to support the growing population of young adults with youth-onset Type 2 diabetes.

Resources and organisation in primary health care are associated with HbA1c level: A nationwide study of 230958 people with Type 2 diabetes mellitus

AIMS

To examine the association between personnel resources and organisational features of primary health care centres (PHCCs) and individual HbA_1c level in people with Type 2 diabetes mellitus (T2DM).

METHODS

People with T2DM attending 846 PHCCs (n=230958) were included in this cross-sectional study based on PHCC-level data from a questionnaire sent to PHCCs in 2013 and individual-level clinical data from 2013 for people with T2DM reported in the Swedish National Diabetes Register, linked to individual-level data on socio-economic status and comorbidities. Data were analysed using a generalized estimating equations linear regression models.

RESULTS

After adjusting for PHCC- and individual-level confounding factors, personnel resources associated with lower individual HbA_1c level were mean credits of diabetes-specific education among registered nurses (RNs) (-0.02mmol/mol for each additional credit; P<0.001) and length of regular visits to RNs (-0.19mmol/mol for each additional 15min; P<0.001). Organisational features associated with HbA_1c level were having a diabetes team (-0.18mmol/mol; P<0.01) and providing group education (-0.20mmol/mol; P<0.01).

CONCLUSIONS

In this large sample, PHCC personnel resources and organisational features were associated with lower HbA_1c level in people with T2DM.

The impact of an intervention to improve diabetes management in primary healthcare professionals' practices in Brazil

AIMS

To evaluate the results of a structured intervention in primary healthcare to improve type 2 diabetes management.

METHODS

The intervention was implemented in 2011-2012 in two cities in the State of Pernambuco, Brazil, and evaluated in 2013 by interviewing healthcare professionals about their practices in all primary care facilities of these two cities (intervention group), and of two paired control cities (control group). Comparisons between the intervention and control groups were made using standard parametric tests.

RESULTS

The percentage of professionals who measured adherence to treatment, developed educational actions to control high-risk situations or prevent complications, or declared that they "explained" the disease to the patients, was higher in the control group (p<0.05). Multidisciplinary involvement, requests for electrocardiograms and referrals to specialists were also more frequent in the control group (p<0.01). The only differences favoring the intervention group were the higher proportion of nurses (p<0.05) and community health workers (p<0.01) trained for diabetes management and a greater frequency of discussing the cases of diabetic patients at team meetings (p<0.01).

CONCLUSIONS

These negative results raise questions about the effectiveness of actions aiming to improve diabetes management in primary care, and reinforce the need for careful evaluation of their impact.

Individualising Chronic Care Management by Analysing Patients' Needs - A Mixed Method Approach

Background

Modern health systems are increasingly faced with the challenge to provide effective, affordable and accessible health care for people with chronic conditions. As evidence on the specific unmet needs and their impact on health outcomes is limited, practical research is needed to tailor chronic care to individual needs of patients with diabetes. Qualitative approaches to describe professional and informal caregiving will support understanding the complexity of chronic care. Results are intended to provide practical recommendations to be used for systematic implementation of sustainable chronic care models.

Method

A mixed method study was conducted. A standardised survey (n = 92) of experts in chronic care using mail responses to open-ended questions was conducted to analyse existing chronic care programs focusing on effective, problematic and missing components. An expert workshop (n = 22) of professionals and scientists of a European funded research project MANAGE CARE was used to define a limited number of unmet needs and priorities of elderly patients with type 2 diabetes mellitus and comorbidities. This list was validated and ranked using a multilingual online survey (n = 650). Participants of the online survey included patients, health care professionals and other stakeholders from 56 countries.

Results

The survey indicated that current care models need to be improved in terms of financial support, case management and the consideration of social care. The expert workshop identified 150 patient needs which were summarised in 13 needs dimensions. The online survey of these pre-defined dimensions revealed that financial issues, education of both patients and professionals, availability of services as well as health promotion are the most important unmet needs for both patients and professionals.

Conclusion

The study uncovered competing demands which are not limited to medical conditions. The findings emphasise that future care models need to focus stronger on individual patient needs and promote their active involvement in co-design and implementation. Future research is needed to develop new chronic care models providing evidence-based and practical implications for the regional care setting.
