2022 update to the position statement by Primary Care Diabetes Europe: a disease state approach to the pharmacological management of type 2 diabetes in primary care.

Type 2 diabetes and its associated comorbidities are growing more prevalent, and the complexity of optimising glycaemic control is increasing, especially on the frontlines of patient care. In many countries, most patients with type 2 diabetes are managed in a primary care setting. However, primary healthcare professionals face the challenge of the growing plethora of available treatment options for managing hyperglycaemia, leading to difficultly in making treatment decisions and contributing to treatment and therapeutic inertia. This position statement offers a simple and patient-centred clinical decision-making model with practical treatment recommendations that can be widely implemented by primary care clinicians worldwide through shared-decision conversations with their patients. It highlights the importance of managing cardiovascular disease and elevated cardiovascular risk in people with type 2 diabetes and aims to provide innovative risk stratification and treatment strategies that connect patients with the most effective care.

Improving management of glycaemic control in people with T2DM in primary care: estimation of the impact on the clinical complications and associated costs.

BACKGROUND: To estimate the potential benefits in terms of avoided complications and cost reduction if the Spanish health system would encourage the intensification of treatment for better glycaemic control in adults with Type 2 diabetes from the current HbA1c target used in clinical practice of 68 mmol/mol to a target of 53 mmol/mol. METHODS: The IQVIA Core Diabetes Model (version 9.0) was used to model the impact of these changes in respect of micro- and macrovascular complications and the associated costs. The modelling was based on data derived from the SIDIAP-Q population database from Catalonia, taking a random cohort of 10,000 people with type 2 diabetes and dividing it into sub-groups based on their baseline HbA1c. RESULTS: The CDM modelling showed that the average cost reduction per person varies depending on baseline HbA1c. The model estimates that after 25 years, people with a baseline HbA1c between 48 and 58 mmol/mol and > 75 mmol/mol show an average cost reduction of €6027 and €11,966, respectively. Applying the per-person cost reduction to the cohorts of the prevalent population in Spain (1,910,374) the overall estimated cost reduction was €14.7 billion over 25 years. The improvements in outcomes resulted in an estimated reduction of more than 1.2 million complications cumulatively over 25 years, of which more than 550,000 relate to diabetic foot and more than 170,000 related to renal disease. CONCLUSION: Over a 25 year period, Spain could considerably reduce costs and avoid major complications if, on a population level, more ambitious glycaemic control, according to Spanish or EU guidelines, could be achieved among people with type 2 diabetes by reducing the HbA1c threshold for treatment intensification. Although there is a slower trajectory for benefits in earlier years, there is a much more rapid benefit gain between years 5 and 15.

Impact on guidelines: The general practitioner point of view.

Primary care physicians are uniquely placed to offer holistic, patient-centred care to patients with T2DM. While the recent FDA-mandated cardiovascular outcome trials offer a wealth of data to inform treatment discussions, they have also contributed to increasing complexity in treatment decisions, and in the guidelines that seek to assist in making these decisions. To assist physicians in avoiding treatment inertia, Primary Care Diabetes Europe has formulated a position statement that summarises our current understanding of the available T2DM treatment options in various patient populations. New data from recent outcomes trials is contextualised and summarised for the primary care physician. This consensus paper also proposes a unique and simple tool to stratify patients into 'very high' and 'high' cardiovascular risk categories and outlines treatment recommendations for patients with atherosclerotic cardiovascular disease, heart failure and chronic kidney disease. Special consideration is given to elderly/frail patients and those with obesity. A visual patient assessment tool is provided, and a comprehensive set of prescribing tips is presented for all available classes of glucose-lowering therapies. This position statement will complement the already available, often specialist-focused, T2DM treatment guidelines and provide greater direction in how the wealth of outcome trial data can be applied to everyday practice.

miR-10b and miR-223-3p in serum microvesicles signal progression from prediabetes to type 2 diabetes.

PURPOSE: Type 2 diabetes frequently remains undiagnosed for years, whereas early detection of affected individuals would facilitate the implementation of timely and cost-effective therapies, hence decreasing morbidity. With the intention of identifying novel diagnostic biomarkers, we characterized the miRNA profile of microvesicles isolated from retroactive serum samples of normoglycemic individuals and two groups of subjects with prediabetes that in the following 4 years either progressed to overt diabetes or remained stable. METHODS: We profiled miRNAs in serum microvesicles of a selected group of control and prediabetic individuals participating in the PREDAPS cohort study. Half of the subjects with prediabetes were diagnosed with diabetes during the 4 years of follow-up, while the glycemic status of the other half remained unchanged. RESULTS: We identified two miRNAs, miR-10b and miR-223-3p, which target components of the insulin signaling pathway and whose ratio discriminates between these two subgroups of prediabetic individuals at a stage at which other features, including glycemia, are less proficient at separating them. In global, the profile of miRNAs in microvesicles of prediabetic subjects primed to progress to overt diabetes was more similar to that of diabetic patients than the profile of prediabetic subjects who did not progress. CONCLUSION: We have identified a miRNA signature in serum microvesicles that can be used as a new screening biomarker to identify subjects with prediabetes at high risk of developing diabetes, hence allowing the implementation of earlier, and probably more effective, therapeutic interventions.

Is quality of life different between diabetic and non-diabetic people? The importance of cardiovascular risks.

BACKGROUND: To analyse and compare the impact of cardiovascular risk factors and disease on health-related quality of life (HRQoL) in people with and without diabetes living in the community. METHODS: We used data of 1,905 people with diabetes and 19,031 people without diabetes from the last Spanish National Health Survey (years 2011-2012). The HRQoL instrument used was the EuroQol 5D-5L, based on time trade-off scores. Matching methods were used to assess any differences in the HRQoL in people with and without diabetes with the same characteristics (age, gender, education level, and healthy lifestyle), according to cardiovascular risk factors and diseases. Disparities were also analysed for every dimension of HRQoL: mobility, daily activities, personal care, pain/discomfort, and anxiety/depression. RESULTS: There were no significant differences in time trade-off scores between people with and without diabetes when cardiovascular risk factors or established cardiovascular disease were not present. However, when cardiovascular risk factors were present, the HRQoL score was significantly lower in people with diabetes than in those without. This difference was indeed greater when cardiovascular diseases were present. More precisely, people with diabetes and any of the cardiovascular risk factors, who have not yet developed any cardiovascular disease, report lower HRQoL, 0.046 TTO score points over 1 (7.93 over 100 in the VAS score) compared to those without diabetes, and 0.14 TTO score points of difference (14.61 over 100 in the VAS score) if cardiovascular diseases were present. In fact, when the three risk factors were present in people with diabetes, HRQoL was significantly lower (0.10 TTO score points over 1 and 10.86 points over 100 in VAS score), obesity being the most influential risk factor. CONCLUSIONS: The presence of established cardiovascular disease and/or cardiovascular risk factors, specially obesity, account for impaired quality of life in people with diabetes.

Aspectos metodológicos de los procesos asistenciales integrados (PAI) / Methodological aspects of integrated care pathways

Un proceso asistencial integrado (PAI) es una herramienta cuyo propósito es aumentar la efectividad de las actuaciones clínicas a través de una mayor coordinación y garantía de continuidad asistencial. Los PAI sitúan al paciente como el eje central de la organización asistencial. Se definen como el conjunto de actividades que realizan los proveedores de la atención sanitaria con la finalidad de incrementar el nivel de salud y el grado de satisfacción de la población que recibe los servicios. La elaboración de un PAI precisa analizar el flujo de actividades, la interrelación entre profesionales y dispositivos asistenciales y las expectativas del paciente. En este artículo se presenta y se discute la metodología para la elaboración de un PAI, así como los factores de éxito para su definición y su efectiva implantación. Se explica también, a modo de ejemplo, el reciente PAI para hipoglucemias en personas con diabetes mellitus tipo 2 elaborado por un equipo multidisciplinar y avalado por varias sociedades científicas (AU)

Older type 2 diabetic patients are more likely to achieve glycaemic and cardiovascular risk factors targets than younger patients: analysis of a primary care database.

BACKGROUND: Older subjects with type 2 diabetes mellitus (T2DM) have differential characteristics compared with middle-aged or younger populations, and require tailored management of the disease. AIMS: To evaluate how clinical characteristics, degree of control of glycaemia and cardiovascular risk factors, presence of chronic complications and treatments differ between older T2DM patients and younger adults. METHODS: Cross-sectional study using data from a population-based electronic database. We retrieved data from 318,020 patients ≥ 30 years diagnosed with T2DM, attended during 2011 in primary care centres in Catalonia, Spain. We performed descriptive and comparative analyses stratified by gender and age subgroups: ≤ 65, 66-75, 76-85 and >85 years. RESULTS: Both men and women across older age subgroups (> 65 years) had longer diabetes duration than younger adults (8.0 vs. 5.6 in men and 8.4 vs. 6.9 years in women; p < 0.001), but better glycaemic control (mean glycated haemoglobin 7.1 vs. 7.7 in men and 7.1 vs. 7.4 in women; p < 0.001), and better combined control of different cardiovascular risk factors (p < 0.001). Moreover, older patients were more likely to achieve glycaemic targets irrespective of having cardiovascular disease. The use of oral antidiabetics decreased with increasing age, and insulin in monotherapy was more frequently prescribed among patients in the older age subgroups. Diabetes-related complications were more frequent in men of all group ages. In the older age subgroups, patients of both sexes had a longer duration of T2DM but better glycaemic control. In this context, the prevalence of diabetic retinopathy decreased unexpectedly with increasing age. CONCLUSION: Control of glycaemia and cardiovascular risk factors was better among older T2DM patients. There is a need for prospective studies to quantify the weight of risk factors in each complication to adapt the therapeutic and care approaches in elderly people.

Consenso sobre la detección y el manejo de la prediabetes. Grupo de Trabajo de Consensos y Guías Clínicas de la Sociedad Española de Diabetes / Consensus on the detection and management of prediabetes. Consensus and Clinical Guidelines Working Group of the Spanish Diabetes Society

En España, según datos del estudio Di@bet. es, un 13,8% de la población adulta padece diabetes y un 14,8% algún tipo de prediabetes (intolerancia a la glucosa, glucemia basal alterada o ambas). Puesto que la detección precoz de la prediabetes puede facilitar la puesta en marcha de medidas terapéuticas que eviten su progresión a diabetes, consideramos que las estrategias de prevención en las consultas de atención primaria y especializada deberían consensuarse. La detección de diabetes y prediabetes mediante un cuestionario específico (test de FINDRISC) y/o la determinación de la glucemia basal en pacientes de riesgo permiten detectar los pacientes con riesgo de desarrollar la enfermedad y es necesario considerar cómo debe ser su manejo clínico. La intervención sobre los estilos de vida puede reducir la progresión a diabetes o hacer retroceder un estado prediabético a la normalidad y es una intervención coste-efectiva. Algunos fármacos, como la metformina, también se han mostrado eficaces en reducir la progresión a diabetes aunque no son superiores a las intervenciones no farmacológicas. Finalmente, aunque no hay pruebas sólidas que apoyen la eficacia del cribado en términos de morbimortalidad, sí que se ha observado una mejora de los factores de riesgo cardiovascular. El Grupo de Trabajo de Consensos y Guías Clínicas de la Sociedad Española de Diabetes, ha elaborado unas recomendaciones que han sido consensuadas con la Sociedad Española de Endocrinología y Nutrición, la Sociedad Española de Endocrinología Pediátrica, la Sociedad Española de Farmacia Comunitaria, la Sociedad Española de Medicina Familiar y Comunitaria, la Sociedad Española de Médicos Generales, la Sociedad Española de Médicos de Atención Primaria, la Sociedad Española de Medicina Interna y la Asociación de Enfermería Comunitaria y la Red de Grupos de Estudio de la Diabetes en Atención Primaria

In Spain, according to the Di@bet. es study, 13.8% of the adult population suffers from diabetes and 14.8% from some form of prediabetes (impaired glucose tolerance, impaired fasting glucose or both). Since early detection of prediabetes can facilitate the implementation of therapeutic measures to prevent its progression to diabetes, we believe that preventive strategies in primary care and specialized clinical settings should be agreed. Screening for diabetes and prediabetes using a specific questionnaire (FINDRISC) and/or the measurement of fasting plasma glucose in high risk patients leads to detecting patients at risk of developing diabetes and it is necessary to consider how they should be managed. The intervention in lifestyle can reduce the progression to diabetes and reverse a prediabetic state to normal and is a cost-effective intervention. Some drugs, such as metformin, have also been shown effective in reducing the progression to diabetes but are not superior to non-pharmacological INTERVENTIONS: Finally, an improvement in some cardiovascular risk factors has been observed although there is no strong evidence supporting the effectiveness of screening in terms of morbility and mortality.

Fifteen years of continuous improvement of quality care of type 2 diabetes mellitus in primary care in Catalonia, Spain.

AIMS: To assess the evolution of type 2 diabetes mellitus (T2DM) quality indicators in primary care centers (PCC) as part of the Group for the Study of Diabetes in Primary Care (GEDAPS) Continuous Quality Improvement (GCQI) programme in Catalonia. METHODS: Sequential cross-sectional studies were performed during 1993-2007. Process and outcome indicators in random samples of patients from each centre were collected. The results of each evaluation were returned to each centre to encourage the implementation of correcting interventions. Sixty-four different educational activities were performed during the study period with the participation of 2041 professionals. RESULTS: Clinical records of 23,501 patients were evaluated. A significant improvement was observed in the determination of some annual process indicators: HbA(1c) (51.7% vs. 88.9%); total cholesterol (75.9% vs. 90.9%); albuminuria screening (33.9% vs. 59.4%) and foot examination (48.9% vs. 64.2%). The intermediate outcome indicators also showed significant improvements: glycemic control [HbA(1c) ≤ 7% (< 57 mmol/mol); (41.5% vs. 64.2%)]; total cholesterol [≤ 200 mg/dl (5.17 mmol/l); (25.5% vs. 65.6%)]; blood pressure [≤ 140/90 mmHg; (45.4% vs. 66.1%)]. In addition, a significant improvement in some final outcome indicators such as prevalence of foot ulcers (7.6% vs. 2.6%); amputations (1.9% vs. 0.6%) and retinopathy (18.8% vs. 8.6%) was observed. CONCLUSIONS: Although those changes should not be strictly attributed to the GCQI programme, significant improvements in some process indicators, parameters of control and complications were observed in a network of primary care centres in Catalonia.

Incidence of complications and mortality in a type 2 diabetes patient cohort study followed up from diagnosis in a primary healthcare centre.

AIMS: To determine the microvascular and macrovascular complications and mortality incidence rates and to identify the related factors in patients recently diagnosed with type 2 diabetes between 1991 and 2000 and followed until 2006. METHODS: Retrospective longitudinal study in a primary healthcare center. Patients without any measure of glycaemia in the 3 years previous to diabetes diagnosis were excluded. Annual incidence rates for microvascular and macrovascular complications and mortality were estimated. Analysis of KaplanMeier survival curves and Cox proportional risk models by gender were done. RESULTS: Of 469 patients [mean age: 60.4 (SD 10.7) years, 53.9% women], 80 died principally of tumoral (38.7%) and cardiovascular (30%) causes. The mean follow-up period was 8.81 years. (SD 3.21). The complication rates per 1000 patients/year (95% CI) were: microvascular complications 29.11 (22.97-36.38), macrovascular complications 24.10 (19.05-30.08) and mortality 19.23 (15.25-23.93), all of those being significantly greater in males except for cerebrovascular disease. Complications and mortality were associated with age, HbA1c, HDL-cholesterol, blood pressure and smoking with a different significance for each gender. HbA1c was related to microvascular complications in both sexes and to macrovascular complications only in women. CONCLUSION: The annual rates for death and complications in a Mediterranean type 2 diabetic patient cohort followed from diagnosis were lower than those published in Anglo-Saxon countries. Males showed higher death and complication rates except in terms of cerebrovascular disease. Predictors of complication and death were different depending on gender. In terms of mortality, unlike in other studies, only one-third of the deaths were for cardiovascular causes.

La aplicación de la HbA1c como único criterio podría retrasar el diagnóstico de la diabetes mellitus tipo 2 / Applying HbA1c as the only criterion for type 2 diabetes would delay its diagnosis

Introducción: La American Diabetes Association ha introducido el valor deHbA1c ≥6,5% para el diagnóstico de la diabetes en 2010. Se desconoce elimpacto de su aplicación en la población mediterránea. Objetivos: Determinarcuántos pacientes dejaríamos de diagnosticar y cuánto tiempo se retrasaríael diagnóstico si se aplicara exclusivamente la HbA1c. Material y métodos:Estudio retrospectivo en 598 pacientes con diabetes mellitus tipo 2(DM2) diagnosticados en un centro de atención primaria entre 1991 y 2000.Los pacientes sin HbA1c en los primeros 3 meses después del diagnósticofueron excluidos. Los pacientes incluidos fueron reclasificados según la HbA1c(<5,7% normoglucemia, 5,7-6,4% categoría de riesgo, y ≥6,5% diabetes)globalmente y según el método diagnóstico utilizado (glucemia ≥140 mg/dL,glucemia ≥126 mg/dL y test de tolerancia oral a la glucosa [TTOG]). Se calculóel intervalo entre el diagnóstico y la primera HbA1c ≥6,5% en los pacientescon HbA1c <6,5%. Resultados: Se incluyeron 377 pacientes, 17 (4,5%)fueron reclasificados como normoglucémicos, 87 (23,1%) como categoría deriesgo y 273 (72,4%) como diabéticos. Sólo un 52,7% de los diagnosticadospor glucemia ≥126 mg/dL serían considerados diabéticos. La media de tiempohasta la primera HbA1c ≥6,5% fue de 3,40 años (desviación estándar [DE]2,35), siendo de 3,80 años (DE 2,49) para los normoglucémicos y de 3,33años (DE 2,34) para la categoría de riesgo. Conclusiones: El uso de la HbA1ccomo único criterio dejaría de diagnosticar o retrasaría el diagnóstico DM2 encasi la mitad de los casos, por lo que sería conveniente mantener la glucemiaplasmática como criterio principal y la HbA1c como un criterio adicional(AU)

Introduction: In 2010 the American Diabetes Association introduced thevalue of HbA1c at ≥6.5% for the diagnosis of diabetes. The impact of its implementationin the Mediterranean population is unknown. Objective: To determinehow many patients would not be diagnosed and how long diagnosisof diabetes would be delayed if only HbA1c was applied. Material andmethods: Retrospective study with 598 type 2 diabetes mellitus (T2DM)patients diagnosed between 1991 and 2000 in an urban primary healthcarecentre. Patients without HbA1c during the 3 months after diagnosis were excluded.Included patients were reclassified by HbA1c (<5.7% normoglycaemic,5.7-6.4% risk category and ≥6.5 diabetes), globally and by diagnosticmethod (glycaemia ≥140 mg/dL, glycaemia ≥126 mg/dL and oral glucosetolerance test). The period between diagnosis and the first HbA1c ≥6.5% inpatients with an HbA1c <6.5% was calculated. Results: 377 patients wereincluded, 17 (4.5%) were reclassified as normoglycaemic, 87 (23.1%) asdiabetes risk category and 273 (72.4%) as diabetics. Only 52.7% of patientsdiagnosed with glycaemia ≥126 mg/dL were considered diabetics. Meantime to the first HbA1c ≥6.5% was 3.40 (standard deviation [SD] 2.35) years,while for normoglycaemic patients it was 3.80 (SD 2.49) years and 3.33 (SD2.34) years for the risk category. Conclusions: The use of HbA1c as a singlecriterion could delay diagnosis of T2DM in almost half of cases. It seems appropriateto maintain plasma glucose as the main criteria and HbA1c as anadditional criteria(AU)

Detección de diabetes tipo LADA en pacientes diabéticos con exceso ponderal. ¿Es adecuado el tratamiento con metformina? / Detection of LADA-type diabetes in overweight diabetic patients. Is treatment with metformin suitable?

Objetivos. Detectar pacientes con diabetes tipo LADA (latent autoinmune diabetes of adult) tipo 1 en diabéticos adultos con sobrepeso y describir las variaciones metabólicas tras administrar metformina. Diseño. Estudio observacional, multicéntrico, basado en una serie de casos. Emplazamiento. Atención primaria, provincia de Barcelona. Participantes. Diabéticos con sobrepeso u obesidad, con diagnóstico de diabetes < 2 años, entre 35 y 65 años de edad, sin complicaciones microvasculares o macrovasculares ni tratamiento farmacológico inicial antidiabético. Intervención. Administración de metformina, 1.700 mg/día. Mediciones. La variable de control metabólico fue la hemoglobina glucosilada (HbA1c); otras variables fueron el índice de masa corporal (IMC), la glucemia en ayunas, la insulinemia, el péptido C y la valoración de la insulinorresistencia (HOMA-IR). Para el diagnóstico de diabetes tipo LADA se determinaron los anticuerpos ICA, anti-GAD y anti-IA2. Resultados. En la muestra de diabéticos estudiada (n = 103) se detectaron 3 casos de LADA tipo 1 (prevalencia del 2,9%; intervalo de confianza del 95%, 0,6-8,3%). Estos pacientes presentaron valores basales más elevados de HbA1c, insulina y sobre todo de HOMA-IR. El tratamiento con metformina mejoró la HbA1c en ambos grupos de pacientes (con o sin LADA de tipo 1). El descenso de la insulinemia al cabo de un año en los pacientes con LADA de tipo 1 fue más marcado que en el resto de diabéticos. Conclusiones. Dada su frecuencia, hay que reflexionar sobre si deberían buscarse con más frecuencia anticuerpos frente a células β pancreáticas en atención primaria. Los pacientes con LADA de tipo 1 presentaron buen control de la HbA1c en tratamiento con metformina y un drástico descenso de la insulina. Faltan estudios que evalúen si la metformina mejora el control glucémico, aunque tal vez no proteja la reserva insulínica, y confrontarla con otros fármacos

Objectives. To detect type-1 LADA (latent auto-immune diabetes in adults) in adults with overweight. To describe the metabolic variations in these patients after metformin treatment. Design. Observational, multi-centre study based on a series of cases. Setting. Health centres in Barcelona province, Spain. Participants. Diabetic patients with overweight or obesity, diagnosed with diabetes for <2 years, aged between 35 and 65, and without clinical micro-macrovascular complications and without initial glycaemia-lowering drug treatment. Intervention. Metformin administration (1700 mg/day). Measurements. The metabolic control variable was HbA1c. Other variables measured were: body mass index (BMI), glucose in fast, insulinaemia, C-peptide, and insulin resistance (HOMA-IR). We determined ICA, GADAb and IA2Ab antibodies to diagnose LADA-type diabetes. Results. In our sample of diabetics (N=103), we detected 3 type-1 LADA cases. These patients had higher levels of HbA1c, insulin and, especially, HOMA-IR. Metformin treatment for one year improved HbA1c in both groups (with and without type-1 LADA). However, the decrease in insulin one year afterwards was greater in type-1 LADA patients. Conclusions. The percentage of type-1 LADA in our sample made us wonder whether we should search for pancreatic antibodies more often in primary care. More studies on the prevalence of type-1 LADA in our country are needed, especially in diabetic patients with overweight. Type-1 LADA patients improved their metabolic control after metformin treatment and showed a drastic decrease in insulin levels. Further studies are needed to evaluate whether metformin improves metabolic control, even though it may not protect insulin reserves, and to contrast metformin with other drugs
