Abstract
BACKGROUND Type 2 Diabetes Miletus (T2DM) is a public health burdens that alarmingly increases and leads to morbidity and mortality over the last decades globally. Its management is multifaceted and adherence to diabetic medications plays great roles in life of T2DM patients. But epidemiology on adherence and its associated factors remain unknown in Rwanda. Therefore, this study determined the extent of non-adherence and its predictors among T2DM patients seeking healthcare services at the Clinique Medicale la Fraternite. METHODS A cross-sectional study among 200 adults' patients with T2DM receiving care in the Medicale la Fraternite clinic was investigated. Bivariate and multivariate logistic regression models were performed based on odds ratio employed to examine associated predictors of non-adherence. The cut-off value for all statistical significances tests were considered at p < 0.05 with 95% for the confidence intervals. RESULTS Overall, more than a half of T2DM patients (53.5%) had poor medication adherence. Being females [OR = 2.1, 95%CI(1.13-3.71), p = 0.002], consuming anti-diabetic drugs for 4-10 years [OR = 2.18, 95%CI(1.09-4.34), p = 0.027], experiencing poor communication with healthcare providers [OR = 2.4; 95%CI (1.36-4.25), p = 0.003] and being perceived as burden of the family [OR = 5.8; 95%CI(1.3-25.7), p < 0.021] had higher odds of non-adherence to anti-diabetic medications. Those with poor HbA1C [OR = 4.26; 95%CI(1.7-10.67), p = 0.002] had 4.26 times higher odds to be non-adherent compared to those with good HbA1C. Respondents with primary [OR = 3.56; 95%CI (1.12-11.28), p = 0.031] and secondary education [OR = 2.96; 95%CI (1.11-7.87), p = 0.03] were more likely to be non-adherent than those with informal education respectively. Those with normal BMI [OR = 5.17; 95%CI(1.63-16.37), p = 0.005] and those with overweight or obese [OR = 3.6; 95%CI (1.04-9.1), p < 0.02] had higher odds of being non-adherent than those with underweight. CONCLUSION Sex, glycaemia, communication with healthcare providers, education and gycosylated hemoglobin were the major predictors of non-adherence. Interventions for tackling this problem through bringing together efforts to stem this epidemic and controlling predictors of non-adherence are urgently recommended.

Abstract
AIMS A post-hoc analysis to assess the impact in people with type 2 diabetes, of increasing doses of basal insulin on glycaemic measures, body weight and hypoglycaemia. RESEARCH DESIGN AND METHODS We included data from prospective, randomized controlled treat-to-target trials of ≥24 weeks' duration in people with type 2 diabetes, uncontrolled on metformin and sulphonylureas, and treated with insulin glargine 100 units/mL (U100), who had at least six fasting plasma glucose (FPG) measurements. The impact of insulin dose on glycated haemoglobin (HbA1c) values, FPG, hypoglycaemia incidence (<3.9 mmol/L [70 mg/dL]), and body weight was analysed. A total of 458 participants from three eligible trials were included. RESULTS The observed relationship between higher basal insulin doses and glycaemic control was non-linear, with increasing insulin dose leading to smaller reductions in FPG and HbA1c for doses >0.3 IU/kg/d, with a plateauing effect at 0.5 IU/kg/d. Total daily dose of insulin >0.5 IU/kg/d resulted in greater weight gain, but without higher rates of hypoglycaemia, compared with insulin doses ≤0.5 IU/kg/d. CONCLUSIONS This analysis indicates that basal insulin doses >0.5 IU/kg/d have diminishing additional impact on improving glycaemic measures, with the disadvantage of additional weight gain. Clinicians should consider anti-hyperglycaemic treatment intensification at doses approaching 0.5 IU/kg/d.

Abstract
Purpose: Medication adherence (MA) is a challenge among patients with chronic diseases worldwide. Little has been reported on the influence of National Health Insurance Scheme (NHIS) on MA among diabetic patients in Nigeria. Objective: To assess the influence of NHIS on MA among outpatient type 2 diabetics in 2 public secondary health facilities in Southwest Nigeria. Method: A cross-sectional study involving 110 consecutively selected outpatient type 2 diabetics (insured, n = 42; uninsured, n = 68) was carried out. The patients’ perceptions of care and the influence of drug cost on MA between the insured and uninsured were compared. The patients’ perceptions of care were assessed using a 25-item pretested questionnaire. The MA was measured using the Morisky MA-8 scale. The use of oral antidiabetic drugs (OADs) was evaluated using a medical chart review. Information about patients’ sociodemographics, year of diagnosis, comorbidities, and types of OADs prescribed was retrieved from the medical records. Descriptive statistics were used for data presentation. A Pearson χ2 was used for test of associations. P values < .05 were considered significant. Results: Majority of the respondents (68 [61.8%]) were uninsured. The insured and the uninsured patients differed in their perceptions of the adequacy of time used by pharmacists for medication counseling (P < .0005). The MA between the groups also differs (P = .0002). The monthly drug cost for OADs was significantly associated with MA (P = .037). Conclusion: The study concluded that the NHIS may positively influence MA among diabetic patients. The drug cost may have contributed significantly to the difference in MA between the groups. More time should be devoted to the counseling of the uninsured patients.

Abstract
BACKGROUND Adherence to antihyperglycemic medication is thought to be suboptimal, but the proportion of patients missing doses, the number of doses missed, and reasons for missing are not well described. This survey was conducted to estimate the prevalence of and reasons for missed doses of oral antihyperglycemic medications among US adults with type 2 diabetes mellitus, and to explore associations between missed doses and health outcomes. METHODS The study was a cross-sectional patient survey. Respondents were contacted via a commercial survey panel and completed an on-line questionnaire via the Internet. Respondents provided information about their use of oral antihyperglycemic medications including doses missed in the prior 4 weeks, personal characteristics, and health outcomes. Weights were calculated to project the prevalence to the US adult population with type 2 diabetes mellitus. Outcomes were compared according to number of doses missed in the past 4 weeks using bivariate statistics and generalized linear models. RESULTS Approximately 30% of adult patients with type 2 diabetes mellitus reported missing or reducing ≥1 dose of oral antihyperglycemic medication in the prior 4 weeks. Accidental missing was more commonly reported than purposeful skipping, with forgetting the most commonly reported reason. The timing of missed doses suggested respondents had also forgotten about doses missed, so the prevalence of missed doses is likely higher than reported. Outcomes were poorer among those who reported missing three or more doses in the prior 4 weeks. CONCLUSIONS A substantial number of US adults with type 2 diabetes mellitus miss doses of their oral antihyperglycemic medications.

Abstract
Type 2 diabetes mellitus (T2DM) is a chronic illness that requires clinical recognition and treatment of the dual pathophysiologic entities of altered glycemic control and insulin resistance to reduce the risk of long-term micro- and macrovascular complications. Although insulin is one of the most effective and widely used therapeutic options in the management of diabetes, it is used by less than one-half of patients for whom it is recommended. Clinician-, patient-, and health care system-related challenges present numerous obstacles to insulin use in T2DM. Clinicians must remain informed about new insulin products, emerging technologies, and treatment options that have the potential to improve adherence to insulin therapy while optimizing glycemic control and mitigating the risks of therapy. Patient-related challenges may be overcome by actively listening to the patient’s fears and concerns regarding insulin therapy and by educating patients about the importance, rationale, and evolving role of insulin in individualized self-treatment regimens. Enlisting the services of Certified Diabetes Educators and office personnel can help in addressing patient-related challenges. Self-management of diabetes requires improved patient awareness regarding the importance of lifestyle modifications, self-monitoring, and/or continuous glucose monitoring, improved methods of insulin delivery (eg, insulin pens), and the enhanced convenience and safety provided by insulin analogs. Health care system-related challenges may be improved through control of the rising cost of insulin therapy while making it available to patients. To increase the success rate of treatment of T2DM, the 2012 position statement from the American Diabetes Association and the European Association for the Study of Diabetes focused on individualized patient care and provided clinicians with general treatment goals, implementation strategies, and tools to evaluate the quality of care.

Abstract
Latin America faces a unique set of challenges in the treatment of type 2 diabetes mellitus (T2DM). This report identifies these challenges and provides a framework for implementation of the strategies, policies and education programs which are needed to optimize the management of this condition. In order to improve future diabetes care, it will be necessary to address existing problems such as limitation of resources, inadequate management of hyperglycemia, and inappropriate education of healthcare team members and people with diabetes. Achieving these goals will require collaborative efforts by many individuals, groups and organizations. These include policymakers, international organizations, healthcare providers, those responsible for setting medical school curricula, patients and society as a whole. It is anticipated that improved/continuing education of healthcare professionals, diabetes self-management education and development of a team approach for T2DM care will lead to optimization of patient-centered care. Implementation of multicentric demonstration studies and rational use of antidiabetic treatments will be necessary to demonstrate the long-term favorable impact of these strategies upon quality of care, prevention of chronic complications, mortality, healthcare costs and patient quality of life.

Abstract
Treat-to-target is a therapeutic concept that considers well defined and specific physiologic targets as aims in controlling the pathophysiology of the disease. It has been widely used in diseases that pathophysiology includes, chronic metabolic and physiological disturbances, namely rheumatic conditions, vascular medicine and diabetes. In diabetes, the availability of "gold-standard" quantitative measures like fasting plasma glucose and glycated hemoglobin make the application of treat-to-target trials especially pertinent. Treatment modalities which have used single therapeutic agents or combinations or in combination with a variety of titration algorithms and implementation protocols have broadened our understanding of diabetes management with specific reference to insulin initiation and maintenance. Treat-to-target trials have been used to investigate a wide variety of questions including efficacy, safety, effect of treatment on comorbidities and patient satisfaction, ideal mechanisms to implement insulin initiation etc. A more generalized acceptance and implementation of treat-to-target trials may finally revolutionize diabetes management by combining aspects of individual care with standard treatment protocols.

Abstract
Good glycaemic control in type 2 diabetes (T2DM) is associated with a reduced risk of diabetes complications; however, achieving and maintaining glycaemic control represents a major challenge to physicians, and despite the availability of a range of antidiabetic therapies, many patients with T2DM will eventually require insulin supplementation to reach target glycaemic levels. Insulin initiation, adjustment of the insulin dose and the need for frequent assessment of blood glucose levels are often complicated by patient and physician misconceptions and concerns regarding its use. For most patients requiring insulin therapy, dose titration is carried out by physicians; however, evidence suggests that this process may not provide optimal glycaemic management for patients. Self-monitoring of blood glucose and self-adjustment of insulin dose (insulin self-titration) is well established in type 1 diabetes, suggesting that similar therapeutic self-management may be beneficial when applied to patients with T2DM. This article reviews the rationale and clinical evidence for insulin self-titration in patients with T2DM with the aim of highlighting the importance of educating patients about insulin therapy and empowering them to manage their diabetes through self-titration of insulin.

Abstract
The rising prevalence of type 2 diabetes poses a serious threat to human health and the viability of many health care systems around the world. Although several prescription medications can play a vital role in controlling symptoms and preventing complications, non-adherence to these therapies is highly prevalent and has been linked to increases in morbidity, mortality, and health care costs. Although a vast array of significant adherence predictors has been identified, the ability to explain or predict non-adherence with known risk-factors remains poor. Further, the definitions, outcomes, and various measures used in the non-adherence literature can be misleading for the unfamiliar reviewer. In this narrative review, a practical overview of important considerations for interpreting adherence endpoints and measures is discussed. Also, an organizational framework is proposed to consider published adherence interventions. This framework may allow for a unique appreciation into areas of limited knowledge and thus highlights targets for future research.

Abstract
OBJECTIVE To describe basal insulin analogue dosing irregularities, the effect of these events on patient functioning, well-being and diabetes management, and the identification of patients most at risk. RESEARCH DESIGN AND METHODS The GAPP2 (Global Attitude of Patients and Physicians 2) study was an online multinational cross-sectional study of patients with type 2 diabetes currently treated with basal insulin, and healthcare professionals (HCPs) involved in the care of such patients. Basal insulin adherence patterns were evaluated with respect to three types of dosing irregularity: missed, mistimed [± 2 hours from prescribed time], and reduced dose over the last 30 days. RESULTS A total of 3042 patients treated with basal insulin analogues and 1222 prescribers completed the full survey; 38% of patients reported any type of basal insulin dosing irregularity in the last 30 days. Patients reported missing (22% on 3 ± 0.16 occasions), mistiming (24% on 4.2 ± 0.21 occasions) or reducing (14% on 4.2 ± 0.24 occasions) basal insulin doses, with 15% of patients reporting multiple types of dosing irregularities. For most patients, missed (83%) and mistimed doses (82%) were unintentional, whereas the majority (87%) of patients reducing doses did so intentionally. Patients who intentionally missed or reduced a dose of basal insulin were significantly more likely to have performed this dosing irregularity on multiple occasions. Fifty-three percent of patients increased the frequency of blood glucose monitoring, and 17% of patients extended the duration of more frequent blood glucose monitoring by one or more days as a result of unintentional missed doses. Reduced dosing was highest in a subset of patients reporting self-treated hypoglycaemia. CONCLUSIONS Basal insulin dosing irregularities including missed, mistimed and reduced doses are common. A significant proportion of patients also report undertaking these irregular dosing behaviours at a frequency that would be considered by prescribers to negatively impact diabetes management. This is despite the potential under-reporting due to recall or social bias that may be a limitation of a self-reported survey around these behaviours.
