The Rate of Insulin use and Suboptimal Glycemic Control among Egyptian Patients with T2DM: Cohort Analysis of Eighth Wave of the International Diabetes Management Practices Study (IDMPS).

AIMS: The International Diabetes Management Practices Study (IDMPS) is an international annual survey aiming to study and characterize the current standards of care for managing DM in developing countries. BACKGROUND: In Egypt, DM represents a substantial burden on the healthcare system, with an estimated 10.9 million patients, ranking it 10th amongst countries with the highest prevalence of DM. Previous studies showed that to maintain safety and achieve treatment goals among diabetic patients, optimal insulin therapy should be selected individually based on the patient's needs. We reported the proportion of Egyptian T2DM patients on insulin therapy who participated in the eighth wave of the IDMPS. METHODS: The 2018 IDMPS wave consisted of cross-sectional and longitudinal phases and aimed to evaluate the proportion of T2DM who were on insulin therapy in 13 countries from four regions. In Egypt, 17 physicians agreed to participate in the present study and were required to include at least one patient. RESULTS: A total of 180 T2DM patients were included in the cross-section phase. At the end of the ninth month of follow-up, data from 170 T2DM patients were available. A total of 39 T2DM patients (21.7%) were on insulin therapy, with a mean duration of 32.4 ± 36.6 months. More than half of the patients (n = 22; 56.4%) were on basal insulin, mainly long-acting (n = 20; 90.9%). The mean basal insulin daily dose was 0.3 ± 0.1 IU/Kg. Notably, 28.2% of the patients received insulin via vials, and 46.2% stated that they were adjusting the insulin dose by themselves. On the other hand, 60.2% of the study population was on oral antidiabetic drugs at the cross-sectional phase. Nearly 17.4% and 27% of the patients in the cross-sectional phase achieved the glycemic target per recommendations of international guidelines and the treating physicians, respectively. At the end of the longitudinal phase, the percentage of T2DM patients who achieved glycemic targets increased to 38.4% and 77.4% as per recommendations of international guidelines and the treating physicians, respectively. Overall, 38.3% of T2DM patients received diabetes education, and 28.9% were involved in an educational program provided by the physician or their clinical staff. Besides, 85.5% of T2DM patients followed their diabetes medication dosage and frequency strictly as prescribed. CONCLUSION: The proportion of insulin use in patients with T2DM aligned with the previous studies from different countries; however, it is still inadequate to achieve the targeted glycemic control. Nearly one-third of Egyptian patients received diabetes education, highlighting the need for adopting a national educational program. Nonetheless, the level of adherence among T2DM from Egypt appears to be high.

Suboptimal glycemic control among subjects with diabetes mellitus in India: a subset analysis of cross-sectional wave-7 (2016) data from the International Diabetes Management Practices Study (IDMPS).

OBJECTIVE: To assess the real-world management practices of subjects with type 2 diabetes mellitus (T2DM) and type 1 diabetes mellitus (T1DM) in India. METHODS: This cross-sectional study was conducted between 7 March 2016 and 15 May 2016 in India as part of the seventh wave (2016) of the International Diabetes Management Practices Study (IDMPS). Adult subjects with T1DM or T2DM visiting physicians during a 2-week recruitment period were included. RESULTS: A total of 55 physicians included 539 subjects who met eligibility criteria. Of 495 subjects with T2DM, 303 were treated with oral glucose lowering drugs (OGLDs) only, 158 were treated with OGLD + insulin, and 27 received insulin only. Among 44 subjects with T1DM receiving insulin, 13 (29.5%) were also treated with OGLD therapy. The most commonly used insulin regimens were basal alone (69/184; 37.5%) and premixed alone (63/184; 34.2%) in subjects with T2DM, and basal + prandial insulin (24/44; 54.5%) in subjects with T1DM. Proportions of subjects achieving glycemic targets were low [glycated haemoglobin (HbA1c) <7%: T1DM = 7.3% (3/44), T2DM = 25.2% (106/495); as targeted by the treating physician: T1DM = 31.8% (14/44), T2DM = 32.1% (59/185); global target: T1DM = 4.8% (2/42) and T2DM = 1.7% (8/482)]. In subjects with T2DM, HbA1c <7% was noted in 11/22 subjects receiving insulin only and 76/260 receiving only OGLDs. Lack of experience in self-managing insulin dosing, poor diabetes education and failure to titrate insulin dosages were the main reasons for non-achievement of glycemic targets. CONCLUSION: Timely insulinization, education and empowerment of people with diabetes may help improve glycemic control in India.

Q-Finder: An Algorithm for Credible Subgroup Discovery in Clinical Data Analysis - An Application to the International Diabetes Management Practice Study.

Addressing the heterogeneity of both the outcome of a disease and the treatment response to an intervention is a mandatory pathway for regulatory approval of medicines. In randomized clinical trials (RCTs), confirmatory subgroup analyses focus on the assessment of drugs in predefined subgroups, while exploratory ones allow a posteriori the identification of subsets of patients who respond differently. Within the latter area, subgroup discovery (SD) data mining approach is widely used-particularly in precision medicine-to evaluate treatment effect across different groups of patients from various data sources (be it from clinical trials or real-world data). However, both the limited consideration by standard SD algorithms of recommended criteria to define credible subgroups and the lack of statistical power of the findings after correcting for multiple testing hinder the generation of hypothesis and their acceptance by healthcare authorities and practitioners. In this paper, we present the Q-Finder algorithm that aims to generate statistically credible subgroups to answer clinical questions, such as finding drivers of natural disease progression or treatment response. It combines an exhaustive search with a cascade of filters based on metrics assessing key credibility criteria, including relative risk reduction assessment, adjustment on confounding factors, individual feature's contribution to the subgroup's effect, interaction tests for assessing between-subgroup treatment effect interactions and tests adjustment (multiple testing). This allows Q-Finder to directly target and assess subgroups on recommended credibility criteria. The top-k credible subgroups are then selected, while accounting for subgroups' diversity and, possibly, clinical relevance. Those subgroups are tested on independent data to assess their consistency across databases, while preserving statistical power by limiting the number of tests. To illustrate this algorithm, we applied it on the database of the International Diabetes Management Practice Study (IDMPS) to better understand the drivers of improved glycemic control and rate of episodes of hypoglycemia in type 2 diabetics patients. We compared Q-Finder with state-of-the-art approaches from both Subgroup Identification and Knowledge Discovery in Databases literature. The results demonstrate its ability to identify and support a short list of highly credible and diverse data-driven subgroups for both prognostic and predictive tasks.

Patients' empowerment, physicians' perceptions, and achievement of therapeutic goals in patients with type 1 and type 2 diabetes mellitus in Mexico.

BACKGROUND: Physicians' perception may not parallel objective measures of therapeutic targets in patients with diabetes. This is an issue rarely addressed in the medical literature. We aimed to analyze physicians' perception and characteristics of adequate control of patients with diabetes. PATIENTS AND METHODS: We studied information on physicians and their patients who participated in the third wave of the International Diabetes Management Practices Study registry in Mexico. This analysis was performed on 2,642 patients, 203 with type 1 diabetes mellitus (T1DM) and 2,439 with type 2 diabetes mellitus (T2DM), treated by 200 physicians. RESULTS: The patients perceived at target had lower hemoglobin A1c (HbA1c) and fasting blood glucose than those considered not at target. However, overestimation of the frequency of patients with HbA1c <7% was 41.5% in patients with T1DM and 31.7% in patients with T2DM (underestimation: 2.8% and 8.0%, respectively). The agreement between the physicians' perception and the class of HbA1c was suboptimal (κ: 0.612). Diabetologists and endocrinologists tested HbA1c more frequently than primary care practitioners, internists, or cardiologists; however, no differences were observed in mean HbA1c, for both T1DM (8.4% vs 7.2%, P=0.42) and T2DM (8.03% vs 8.01%, P=0.87) patients. Nevertheless, insulin users perceived at target, who practiced self-monitoring and self-adjustment of insulin, had a lower mean HbA1c than patients without these characteristics (mean HbA1c in T1DM: 6.8% vs 9.6%, respectively; mean HbA1c in T2DM: 7.0% vs 10.1%, respectively). CONCLUSION: Although there is a significant physicians' overestimation about the optimal glycemic control, this global impression and characteristics of patients' empowerment, such as self-monitoring and self-adjustment of insulin, are associated with the achievement of targets.

Cardiovascular diseases and diabetes as economic and developmental challenges in Africa.

Current estimates and projections suggest that the burden of cardiovascular diseases (CVDs), diabetes and related risk factors in African countries is important, somewhat unique and rapidly growing. Various segments of the population are affected; however, the group mostly affected is young adults residing in urban areas, and increasingly those in the low socioeconomic strata. The African milieu/environment is compounded by weak health systems, which are unable to cope with the looming double burden of communicable and chronic non-communicable diseases. This review discusses the economic and developmental challenges posed by CVDs and diabetes in countries in Africa. Using several lines of evidence, we demonstrate that the cost of care for major CVDs and diabetes is beyond the coping capacities of individuals, households, families and governments in most African countries. We have reviewed modeling studies by the International Diabetes Federation (IDF) and other major international agencies on the current and projected impact that CVDs and diabetes have on the economy and development of countries in the region. Locally, appropriate strategies to limit the impact of the conditions on the economies and development of countries in Africa are suggested and discussed. These include monitoring diseases and risk factors, and primordial, primary and secondary preventions implemented following a life-course perspective. Structural, logistic, human capacity and organizational challenges to be surmounted during the implementations of these strategies will be reviewed.

Características generales y esquemas de tratamiento en pacientes con diabetes tipo 2, participantes en el estudio IDMPS (International Diabetes Management Practice Study) en Costa Rica / Basic characteristics and treatment regimens in people with type 2 diabetes who participated in the International Diabetes Management Practices Study in Costa Rica

Antecedentes: el International Diabetes Management Practice Study es un estudio mundial, observacional, que tiene como propósito determinar el estándar de tratamiento de los pacientes con diabetes mellitus en las diferentes regiones del mundo, y la adherencia a las guías internacionales con respecto al abordaje y manejo de estos pacientes. A nivel mundial, 15016 pacientes con diabetes tipo 2 participaron en el estudio, previamente publicado por Ringborg et al. en la revista International Journal of Clinical Practice, en 2009. La siguiente publicación corresponde a la segunda etapa del estudio que analizó a los pacientes participantes de Costa Rica. Resultados: en Costa Rica se valoró 49 pacientes de la consulta privada de 5 médicos endocrinólogos, en un periodo que comprendió del 22 de marzo al 24 de abril de 2007. El valor promedio de la glicemia en ayunas para los pacientes fue de 140,45mg/dL ± 56,3. Con respecto al control glicémico, el estudio encontró que el 60% de los participantes presentó una HbA1c > 7%, y el 17,5% de los pacientes presentó HbA1c mayor al 9%. Todos los pacientes valorados estaban recibiendo algún tipo de terapia farmacológica: el 63,6% de los pacientes con hipoglicemiantes orales, y el 45,5% de los pacientes tratados con insulina alcanzó la meta de HbA1c < 7%. Solo el 22,2% de los pacientes tratados con la combinación de hipoglicemiantes orales más insulina, llegó a la meta. Conclusión: el estudio muestra como la mayoría de los pacientes (60%) no logra alcanzar la meta de un adecuado control glicémico (HbA1c < 7%), aunque se ha establecido que un adecuado control glicémico reduce la incidencia de complicaciones micro y macrovasculares. Debe haber un mayor énfasis en la atención intensiva para mejorar el manejo de los pacientes con diabetes tipo 2 en Costa Rica.

Background: The International Diabetes Management Practice Study was a worldwide observational study with the aim to determine the standard of care of diabetic patients in different regions around the world and the adherence to the international guidelines regarding diabetic care and management. Around the world 15,016 patients with type 2 diabetes were enrolled in this study, published previously by Ringborg et al, in the International Journal of Clinical Practice in 2009. The following study corresponds to the sub study which analyzed the patients who participated in Costa Rica. Results: In Costa Rica 49 type 2 diabetic patients were recruited from the private practice of 5 endocrinologists from March 22nd to April 24th, 2007. The mean fasting blood sugar value of the patients studied was of 140.45mg/dL ± 56.3. With respect to glycemic control, the study showed that 60% of patients had an HbA1c > 7% and 17.5% of them had a value greater than 9%. All the patients who were evaluated had some type of pharmacologic agent in their therapeutic regimen. Around sixty-three percent (63.6%) of the patients who were treated with oral antidiabetic agents and 45.5% with insulin alone reached the target of an HbA1c < 7%, respectively. To a lesser extent (22.2%) patients who were treated with both types of medications reached that goal. Conclusion: In this study the majority of patients (60%), did not meet criteria for an adequate glycemic control (HbA1c < 7%) despite the broad scientific evidence available which demonstrates that an adequate glycemic control effectively reduces micro and macrovascular complications. More emphasis needs to be added to improve treatment for patients with type 2 diabetes in Costa Rica.
