Impact of hypoglycemia on patients with type 2 diabetes mellitus and their quality of life, work productivity, and medication adherence

Young adults with type 2 diabetes experience high rates of Level 3 Hypoglycemia: A subgroup analysis of the Real-World iNPHORM cohort

AIMS

This study evaluated the incidence proportion and rate of self-reported Level 3 hypoglycemia and explored associated risk factors in young adults with type 2 diabetes (T2D).

METHODS

Subgroup analyses with a one-year U.S.-wide T2D dataset were performed. Retrospective and prospective data on Level 3 hypoglycemia and participant characteristics were analyzed for 207 young adults (18-39 years old) and 436 middle-aged adults (40-64 years old). Age group-stratified multivariable negative binomial regression was used to identify factors associated with Level 3 hypoglycemia.

RESULTS

Young adults exhibited a threefold higher incidence of Level 3 hypoglycemia events requiring medical assistance compared to the middle-aged cohort at baseline (p < 0.001). During follow-up, the young adults experienced a twofold higher incidence proportion of Level 3 hypoglycemia (p < 0.001), and n a fivefold higher annualized rate (p < 0.001); they also reported greater hypoglycemia fear (p < 0.001). Distinct sociodemographics, general health and lifestyle factors, diabetes medical history, and diabetes therapy and technology use characteristics were observed in the young-adult group, as were unique risk factors for Level 3 hypoglycemia frequency CONCLUSION: Our results suggest that young adults with T2D are at particularly high risk of Level 3 hypoglycemia, with attributes that differ from those of the traditional middle-aged cohort.

Adverse Health Outcomes Associated with Hypoglycemia Following Bariatric Surgery

Introduction: Hypoglycemia is prevalent among patients postbariatric surgery, but its clinical implications remain unclear. The purpose of this study was to examine the longitudinal associations of hypoglycemia (i.e., occurrence in the past 3 months, frequency in the past 7 days, number of severe episodes in the past 3 months, and symptoms) with depressive symptoms, quality of life (QoL), work productivity, and weight loss over an 84-month follow-up period after bariatric surgery. Methods: This secondary analysis used data from the Longitudinal Assessment of Bariatric Surgery-2 study. Hypoglycemia, depressive symptoms, QoL, and work productivity were self-reported. Weight was primarily based on objective measures. Linear mixed modeling with time-lagged techniques was used for analysis, adjusting for potential covariates such as age and gender. Results: Across the 84-month follow-up, 20%-30% of participants (N = 552) reported experiencing hypoglycemia in the past 3 months. Hypoglycemia occurrence was positively associated with depressive symptoms [β = 2.4; 95% confidence interval (CI): 1.7, 3.0] and negatively associated with physical (β = -4.2; 95% CI: -5.1, -3.3) and mental QoL (β = -3.4; 95% CI: -4.4, -2.4). These associations became stronger with increased frequency of hypoglycemia, a higher number of severe episodes, and the presence of symptoms. Additionally, hypoglycemia occurrence was associated with several domains of work productivity, including presenteeism (β = 5.8; 95% CI: 3.4, 8.2), work productivity loss (β = 5.6; 95% CI: 2.6, 8.6), and activity impairment (β = 8.8; 95% CI: 6.0, 11.6), with the strength of these associations increasing with greater hypoglycemic frequency. Conclusions: This study highlights the critical role of hypoglycemia in patients' physical and psychosocial well-being postbariatric surgery. Future studies employing more rigorous measures of hypoglycemia and expanded outcomes (e.g. cognitive function) are needed to fully understand its clinical relevance.

Efficacy and safety of switching to insulin glargine 300 U/mL in people with type 2 diabetes uncontrolled on basal insulin in China: A post hoc subpopulation analysis of the INITIATION study

AIMS

To evaluate the efficacy and safety of insulin glargine 300 U/mL (Gla-300) in people with uncontrolled type 2 diabetes (T2D) switching from another basal insulin (BI).

MATERIALS AND METHODS

INITIATION was an interventional, single-arm, phase IV study conducted in China. In this post hoc subpopulation analysis, the efficacy and safety of switching to Gla-300 was investigated in individuals with uncontrolled T2D (HbA1c 7.5%-11.0% [58-97 mmol/mol]) with previous BI. The primary endpoint was HbA1c change at week 24. Other measures of glycaemia, hypoglycaemia, insulin dose and weight change were assessed.

RESULTS

Three hundred and two participants switched to Gla-300 from another BI, including 232 from insulin glargine 100 U/mL (Gla-100) and 55 from insulin degludec (IDeg). At week 24, the mean ± standard error (SE) HbA1c change from baseline was -0.87% ± 0.06% (-9.5 ± 0.7 mmol/mol; p <0.001). Significant reductions in fasting plasma glucose (least-squares mean [LSM] change -1.13 mmol/L) and fasting self-measured blood glucose (LSM change -1.36 mmol/L) were also observed (both p <0.001). The mean daily BI dose increased from 18.86 U (0.27 U/kg) at baseline to 28.83 U (0.41 U/kg) at week 24. During the 24-week treatment period, the incidence of any hypoglycaemia was 43.8% for all hypoglycaemia and 15.1% for nocturnal hypoglycaemia; the incidence of severe hypoglycaemia was low (0.7%). Minimal body weight change was documented.

CONCLUSIONS

Gla-300 improved glycaemic control with a relatively low hypoglycaemia risk and minimal weight gain in Chinese people with T2D uncontrolled on previous BI.

Diabetes Mellitus and its Association with Work Patterns and Characteristics: A Narrative Review

Diabetes mellitus is a leading cause of disability with adverse effects on the quality of life. It also affects occupational health by impacting several work-related parameters. This review discusses the relationship between diabetes and absenteeism, presenteeism, work impairment and unemployment. The association between work and diabetic complications such as neuropathic pain, diabetic foot, psychological issues and hypoglycemia due to treatment is also examined. Evidence points to a relationship between diabetes and absenteeism, reduced work productivity, and, thus, overall work impairment. A stronger negative impact on work performance is mediated by painful diabetic neuropathy and diabetic foot. In addition, psychological distress has been positively correlated with total workdays lost and frequency of absence. Depression in the diabetic population has also been linked with increased absenteeism, presenteeism, and work disability. Moreover, hypoglycaemia induced by antidiabetic medication may affect work attendance and performance. Finally, diabetes has been associated with inequality in the work environment, lower job satisfaction and higher unemployment rates, mainly because of its complications.

Prioritizing Patient Experiences in the Management of Diabetes and Its Complications: An Endocrine Society Position Statement

Diabetes can be an arduous journey both for people with diabetes (PWD) and their caregivers. While the journey of every person with diabetes is unique, common themes emerge in managing this disease. To date, the experiences of PWD have not been fully considered to successfully implement the recommended standards of diabetes care in practice. It is critical for health-care providers (HCPs) to recognize perspectives of PWD to achieve optimal health outcomes. Further, existing tools are available to facilitate patient-centered care but are often underused. This statement summarizes findings from multistakeholder expert roundtable discussions hosted by the Endocrine Society that aimed to identify existing gaps in the management of diabetes and its complications and to identify tools needed to empower HCPs and PWD to address their many challenges. The roundtables included delegates from professional societies, governmental organizations, patient advocacy organizations, and social enterprises committed to making life better for PWD. Each section begins with a clinical scenario that serves as a framework to achieve desired health outcomes and includes a discussion of resources for HCPs to deliver patient-centered care in clinical practice. As diabetes management evolves, achieving this goal will also require the development of new tools to help guide HCPs in supporting PWD, as well as concrete strategies for the efficient uptake of these tools in clinical practice to minimize provider burden. Importantly, coordination among various stakeholders including PWD, HCPs, caregivers, policymakers, and payers is critical at all stages of the patient journey.

Comparative Study on Efficacy of Empagliflozin Versus Sitagliptin, as an Add-on Therapy to Metformin in Type 2 Diabetic Patients

Introduction

More than 28.7 million individuals throughout the globe suffer from diabetes mellitus, with an estimated 11 percent of the population living with the condition in India. Changes in lifestyle and a variety of treatment plans are used in management. Metformin is a key drug for glycemic control, both when used alone and in combination. Our research compares the effectiveness of glycemic control achieved by empagliflozin plus sitagliptin.

Methods

This study took place from November 2022 to April 2023 at the tertiary care hospital. The study did not begin until the ethical review was completed. There were two groups of patients, A and B. Everyone received a daily dose of Metformin 1,000 milligrams. Sitagliptin (50 mg twice daily) was administered to individuals in Group A, whereas Empagliflozin (10 mg once daily) was given to those in Group B. After three months of therapy, HbA1c was used to compare the two groups' levels of glycemic control to those at the start of treatment. To do this, we employed a proforma. Version 25 of the Statistical Package for the Social Sciences (SPSS Inc., Chicago, USA) was used for the analysis.

Results

The average age of the 300 patients that participated in the trial was 42.33. There were 57.67% men and 42.33% females. "The mean reduction in HbA1c from baseline in Group A was -0.65 ± 0.11% and in Group B was -1.34 ± 0.13% with statistically significant P-value (P-value = 0.000)."

Conclusion

The combination of Empagliflozin and Metformin is superior to that of Sitagliptin and Metformin for the maintenance of glycemic control.

Development of a Patient-Reported Outcome (PRO) Measure to Assess Emotional Impact of Treatment for Type 2 Diabetes

INTRODUCTION

Patients receiving treatment for type 2 diabetes (T2D) may experience an emotional impact associated with treatment-related changes. A patient-reported outcome (PRO) measure assessing both positive and negative emotional impact of medication treatment for T2D is needed to better understand the patient experience of treatment. The purpose of this qualitative study was to explore the emotional impact of treatment for T2D and support the development of a questionnaire to assess the emotional impact of treatment for T2D.

METHODS

Exit interviews were conducted with patients with T2D participating in the SURPASS-2 and SURPASS-3 trials for tirzepatide. The exit interviews included a concept elicitation section focusing on the emotional impact of their study treatment. Results were used to develop two questionnaires that were evaluated in cognitive interviews with patients with T2D.

RESULTS

The concept elicitation interviews included 28 patients (mean age 57.6 years; 64.3% female). Most patients reported positive changes in emotions associated with tirzepatide, including increased confidence (n = 23; 82.1%), hope (n = 23; 82.1%), self-esteem (n = 23; 82.1%), relief (n = 22; 78.6%), optimism (n = 21; 75.0%), sense of control (n = 21; 75.0%), happiness (n = 15; 53.6%), and motivation (n = 15; 53.6%), as well as reduced worry/anxiety (n = 19; 67.9%). Negative emotional impact was less commonly reported but included frustration (n = 2; 7.1%), worry/anxiety (n = 1; 3.6%), fear (n = 1; 3.6%), and feeling depressed (n = 1; 3.6%). Two new PROs, the Emotional Impact of Diabetes Treatment Questionnaires (EIDTQ, status and comparison versions), were developed based on these finding. The status version assesses the emotional impact of current treatment, while the comparison version allows for comparison of the current treatment to a previous treatment. The questionnaires were refined on the basis of cognitive interviews with 20 additional patients (mean age 58.3 years; 60.0% female), and results suggest that the final instruments were clear, comprehensible, and relevant to patients.

CONCLUSION

The EIDTQ-Status and Comparison measures can be used as a supplement to clinical outcomes, such as hemoglobin A1c (HbA1c) and body weight, to provide a broader picture of the patient's emotional experience with medication treatment for T2D.

Real-time continuous glucose monitoring improves glycemic control and reduces hypoglycemia: Real-world data

AIM

To study the effect of real time continuous glucose monitor (RT-CGM) use on glycemic parameters in patients with diabetes mellitus (DM) in real world practice.

METHODS

We retrospectively studied 91 adult subjects with DM who had been using Dexcom™ RT-CGM. Two consecutive hemoglobin A1c (HbA1c), both prior to and after at least 3 months of RT-CGM initiation, were collected. A total of 31 subjects completed a 5-14 day user blinded CGM using a Freestyle Libre™ prior to RT-CGM initiation. The first two week period following at least 3 months use of RT-CGM was analyzed for CGM metrics.

RESULTS

A total of 51.6 % of subjects had T1DM, 34.1 % used continuous subcutaneous insulin infusion (CSII), and 62.6 % had DM for > 10 years. Both HbA1c obtained following RT-CGM initiation decreased significantly compared to baseline (8.11 + 1.47% vs 7.69 + 1.25 %; P = 0.002 & 8.16 + 1.51 % vs 7.62 + 1.06 %; P = 0.001). Subjects with baseline HbA1c > 7.0 % showed even more robust reduction in both HbA1c after RT-CGM initiation (8.74 + 1.24 % vs 7.99 + 1.22 %; P = 0.000 & 8.74 + 1.32 % vs 7.85 + 1.07 %; P = 0.001). On comparison of CGM metrics, there was a significant reduction in time spent in hypoglycemia (sugars < 70 mg/dl) including severe hypoglycemia (sugars < 54 mg/dl) after initiation of the RT-CGM (9.16 + 8.68 % vs 1.29 + 2.21 %; P = <0.001 & 4.58 + 5.43 % vs 0.28 + 0.58 %; P = <0.001). CoV of glucose was also decreased significantly (39.61 + 9.36 % vs 31.06 + 6.74 %; P = <0.001) with RT- CGM use.

CONCLUSION

RT-CGM use for at least 3 months in patients with DM results in meaningful HbA1c reductions with stable glycemic control without increasing the risk of hypoglycemia.

Randomized Clinical Trial on Efficacy of Empagliflozin Versus Sitagliptin, In Addition to Metformin in Type 2 Diabetic Patients

Introduction Diabetes mellitus is a syndrome affecting more than 28.7 million people worldwide and its prevalence in Pakistan is reported to be about 11%. Management includes lifestyle changes and varied therapeutic regimens. Metformin (MET) alone and in combinations is considered as an important agent for glycemic control. Our study is based on MET combination therapy with empagliflozin versus sitagliptin in order to achieve glycemic control. Methods This randomized clinical trial was conducted in the Department of Medicine and Allied of Federal Government Polyclinic Hospital, Islamabad, from January 2022 till June 2022. The ethical approval letter numbered FGPC. 1-1/2022/Ethical Committee was taken before the commencement of the trial. The patients were divided into group A and group B. All patients were given MET 1000mg twice a day. Group A patients were additionally given sitagliptin 50mg twice daily whereas Group B patients were additionally given empagliflozin 10mg once daily. Glycemic control was documented with HbA1c at the start of treatment and after three months of treatment in both groups. A proforma was used to collect data. Analysis of the data was performed using the Statistical Package for the Social Sciences version 17 (SPSS Inc., Chicago, USA). Results A total of 126 patients were included in the study with a mean age of 53.53 ± 6.49. 81.7% were males while 18.3% were females. The mean reduction in HbA1c from baseline in group A was -0.81 ± 0.19% and in group B was -1.13 ± 0.24% with statistically significant p-value (p-value = 0.000). Conclusion Empagliflozin in combination with metformin is more efficacious in maintaining glycemic control as compared to sitagliptin in combination with metformin.

Type 2 diabetes mellitus patients' lived experience at a tertiary hospital in Ekiti State, Nigeria

Diabetes mellitus is a complex and chronic metabolic disorder that is associated with multiple complications and disabilities. This contributes to increased mortality and poor quality of life among affected individuals. The study explored the lived experience of patients with type 2 diabetes mellitus at a Teaching Hospital in Ekiti State, Nigeria. A mixed method of qualitative and quantitative design was adopted. For the quantitative aspect, a convenience sampling technique was employed while the instrument used was an adapted questionnaire. For the qualitative aspect, focus-group discussion involving twenty-four participants was conducted, and the sample size was determined by data saturation. Qualitative data was analyzed using thematic transcription. Findings revealed that 55.6% of the participants were females while 63.5% had tertiary education. Majority (18 of 24) of the respondents experienced body weakness, frequent urination and excessive thirst when diagnosed of diabetes mellitus and later experienced occasional body weakness, burning sensation, tingling and numbness of the feet, fatigue, loss of libido, and occasional visual disturbance. Two-third of the participants reported being indifferent when they were informed about their condition. However, majority of the participants perceived that the cause of diabetes mellitus was heredity. More than two-third of the participants did not experience reduction in their normal daily activities but rather experienced occasional emotional disturbances, anxiety and challenges with self-management of diabetes and this was associated with maintaining a normo-glycemic state due to the financial implications of drugs and dietary modifications.

Investigating the day-to-day impact of hypoglycaemia in adults with type 1 or type 2 diabetes: design and validation protocol of the Hypo-METRICS application

INTRODUCTION

Hypoglycaemia is a frequent adverse event and major barrier for achieving optimal blood glucose levels in people with type 1 or type 2 diabetes using insulin. The Hypo-RESOLVE (Hypoglycaemia-Redefining SOLutions for better liVEs) consortium aims to further our understanding of the day-to-day impact of hypoglycaemia. The Hypo-METRICS (Hypoglycaemia-MEasurement, ThResholds and ImpaCtS) application (app) is a novel app for smartphones. This app is developed as part of the Hypo-RESOLVE project, using ecological momentary assessment methods that will minimise recall bias and allow for robust investigation of the day-to-day impact of hypoglycaemia. In this paper, the development and planned psychometric analyses of the app are described.

METHODS AND ANALYSIS

The three phases of development of the Hypo-METRICS app are: (1) establish a working group-comprising diabetologists, psychologists and people with diabetes-to define the problem and identify relevant areas of daily functioning; (2) develop app items, with user-testing, and implement into the app platform; and (3) plan a large-scale, multicountry study including interviews with users and psychometric validation. The app includes 7 modules (29 unique items) assessing: self-report of hypoglycaemic episodes (during the day and night, respectively), sleep quality, well-being/cognitive function, social interactions, fear of hypoglycaemia/hyperglycaemia and work/productivity. The app is designed for use within three fixed time intervals per day (morning, afternoon and evening). The first version was released mid-2020 for use (in conjunction with continuous glucose monitoring and activity tracking) in the Hypo-METRICS study; an international observational longitudinal study. As part of this study, semistructured user-experience interviews and psychometric analyses will be conducted.

ETHICS AND DISSEMINATION

Use of the novel Hypo-METRICS app in a multicountry clinical study has received ethical approval in each of the five countries involved (Oxford B Research Ethics Committee, CMO Region Arnhem-Nijmegen, Ethikkommission der Medizinischen Universität Graz, Videnskabsetisk Komite for Region Hovedstaden and the Comite Die Protection Des Personnes SUD Mediterranne IV). The results from the study will be published in peer review journals and presented at national and international conferences.

Behavioral Sciences in the Optimization of Pharmacological and Non-Pharmacological Therapy for Type 2 Diabetes

Type 2 diabetes mellitus is one of the main chronic diseases worldwide, with a significant impact on public health. Behavioral changes are an important step in disease prevention and management, so the way in which individuals adapt their lifestyle to new circumstances will undoubtedly be a predictor of the success of the treatments instituted, contributing to a reduction in the morbidity and mortality that may be associated with them. It is essential to prepare and educate all diabetic patients on the importance of changing behavioral patterns in relation to the disease, with health professionals assuming an extremely important role in this area, both from a pharmacological and non-pharmacological point of view, and also ensuring the monitoring of the progress of these measures. Diabetes is a chronic disease that requires a high self-management capacity on the part of patients in order to achieve success in treating the disease, and non-adherence to therapy or non-compliance with the previously defined plan, together with an erratic lifestyle, will contribute to failure in controlling the disease. The lower adherence to pharmacological and non-pharmacological treatment in diabetes is mainly correlated to socio-economic aspects, lower health literacy, the side effects associated with the use of antidiabetic therapy or even the concomitant use of several drugs. This article consists of a narrative review that aims to synthesize the findings published in the literature, retrieved by searching databases, manuals, previously published scientific articles and official texts, following the methodology of the Scale for Assessment of Narrative Review Articles (SANRA). We aim to address the importance of behavioral sciences in the treatment of diabetes, in order to assess behavior factors and barriers for behavior changes that have an impact on the therapeutic and non-therapeutic optimization in patients with type 2 diabetes mellitus control.

Diabetes severity measured by treatment control status and number of anti-diabetic drugs affects presenteeism among workers with type 2 diabetes

BACKGROUND

The number of people with diabetes is increasing and resulting in major economic losses. Presenteeism accounts for the majority of economic losses, so measures against presenteeism are important. This study investigated the relationship between severity of type 2 diabetes and presenteeism.

METHODS

A cross-sectional study was conducted among workers over 40 years of age. Participants were classified as normal group or diabetic treatment group using their medical examination results and health insurance claims data. Diabetic treatment groups were described by degree of treatment control: Good (HbA1c < 7%), Intermediate (7% ≤ HbA1c < 8%), and Poor (8% ≤ HbA1c). Therapy type was also divided into monotherapy and combination therapy. Logistic regression analysis was performed to predict presenteeism loss using the Quantity and Quality method.

RESULTS

Data on 13,271 workers were analyzed. Presenteeism loss was significantly higher in all treatment control groups compared with the normal group, particularly for the intermediate and poor control groups. The monotherapy group did not differ from the normal group, but presenteeism loss was significantly higher in the combination therapy group than the normal group.

CONCLUSIONS

Presenteeism loss in workers with diabetes may be affected by diabetes severity, and even if treatment control were good, presenteeism loss could occur when the number of anti-diabetic drugs was high. Therefore, it is important to provide early intervention and continuous support as a preventive measure against not only diabetes and diabetes-related complications but also presenteeism.

The Impact of Diabetes Status on Presenteeism in Japan

OBJECTIVE

This study aimed to investigate the impact of diabetes status on presenteeism in companies in Japan.

METHODS

A cross-sectional study was conducted among workers aged 40 years or older. Using medical examination results and health insurance claims data, participants were classified as normal, borderline, or diabetic. The diabetic group was further classified as untreated or treated. The Quantity and Quality (QQ) method was used as an evaluation index of presenteeism. Logistic regression analysis was performed to predict presenteeism loss.

RESULTS

Data on 13,292 people were analyzed. Presenteeism loss was significantly higher in the diabetic group versus the normal group. The untreated group did not differ from the normal group, but presenteeism loss was significantly higher in the treated group.

CONCLUSIONS

Presenteeism loss may occur among diabetic workers in Japan and can be caused by diabetes treatment.

The association between diabetes-related distress and fear of hypoglycaemia in patients with type 2 diabetes mellitus: A cross-sectional descriptive study

AIM

The study aimed to explore the association between diabetes-related distress as a dependent variable and fear of hypoglycaemia as a independent variable in Chinese individuals with type 2 diabetes, which can provide a basis for the development of effective nursing interventions.

DESIGN

A cross-sectional descriptive study.

METHODS

Pre-piloted scales were used to determine whether they experienced fear of hypoglycaemia and whether this impacted upon their management of the disease. From June-October 2019, participants were asked to complete the "hypoglycaemia fear survey" and "diabetes distress scales" to assess levels of fear and distress. Stepwise multivariate regression analysis was applied to reveal relationship between distress as a dependent variable and fear as a independent variable. Covariates included demographic, clinical or lifestyle factors.

RESULTS

A total of 258 participants were recruited for the survey, and they were characterized by little or no distress (39.53%), moderate distress (45.35%) and high distress (15.12%). The prevalence of moderate to severe distress in patients was 60.47%. Increased diabetes-related distress was strongly correlated with increased fear of hypoglycaemia and closely associated with the scores of the worry and behaviour subscales. These results indicated that 62.3% of diabetes-related distress may be explained by fear of hypoglycaemia.

CONCLUSION

Increased diabetes-related distress is associated with increased fear of hypoglycaemia in individuals with type 2 diabetes.

One Hundred Years of Insulin: Value Beyond Price in Type 2 Diabetes Mellitus

Type 2 diabetes mellitus is a chronic, progressive disease that frequently necessitates treatment with basal insulin to maintain adequate glycaemic control. In considering the value of different basal insulin therapies, although acquisition costs are of increasing importance to budget-constrained healthcare systems, value beyond simple price considerations should be taken into account. Whilst human basal insulins are of lower acquisition cost compared to long-acting insulin analogues, this difference in price has the potential to be offset in terms of total healthcare system value through the ultra-long duration of action and low variability in glucose-lowering activity which have been translated into real clinical benefits, in particular a reduced risk of hypoglycaemic events. The maintenance of glycaemic targets and avoidance of hypoglycaemia that have been associated with insulin analogues represent a significant value consideration, beyond price, for the use of basal insulin analogues to manage type 2 diabetes mellitus from the perspective of all stakeholders within the healthcare system, including payers, healthcare professionals, patients and society.

Is there a need to measure preand post-capillary blood glucose following a cardiac exercise class?

Exercise training is associated with positive health outcomes in people with cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). However, fear of hypoglycaemia is a potential barrier to participants attending a cardiac exercise class. Therefore, we assessed the capillary blood glucose (CBG) responses to the Imperial NHS Trust cardiac exercise class. Forty patients (median age 66 years, interquartile range [IQR] 57-74 years) with CVD and T2DM treated with insulin and/or sulfonylureas completed a cardiac exercise class. CBG was measured immediately before and after the exercise class. Subgroup analysis assessed CBG levels in patients who had consumed food <2 and ≥2 hours and had taken their insulin and/or sulfonylureas <4 and ≥4 hours before the exercise class. Overall, post-exercise CBG had significantly decreased (-3.0 mmol/L, p≤0.0001). Subgroup analyses demonstrated significant reductions in CBG in both food consumption groups (<2 hours -2.9 mmol/L, p≤0.0001, and ≥2 hours -3.1 mmol/L, p≤0.0001) and medication groups (<4 hours -3.4 mmol/L, p≤0.0002, and ≥4 hours -2.7 mmol/L, p≤0.0001). However, there were no significant differences in CBG between the food consumption groups and the medication groups, respectively (p=0.7 and p=0.3). Cardiac exercise classes resulted in significant reductions in CBG levels. However, the timing of food consumption or medication intake did not influence the magnitude of CBG decline after the cardiac exercise class.

A review of GLP-1 receptor agonists in type 2 diabetes: A focus on the mechanism of action of once-weekly agents

WHAT IS KNOWN AND OBJECTIVE

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are one of the preferred approved treatment options for people with type 2 diabetes (T2D) and inadequate glycaemic control. The objective of this review is to provide a general clinical overview of the similarities and differences in the mechanisms of action (MoA) of the once-weekly GLP-1 RA class of medications, highlighting the role of pharmacists in providing optimal medication management, education and care for people with diabetes.

METHODS

This is a narrative review of the published literature regarding the MoA of the currently available once-weekly GLP-1 RAs in T2D.

RESULTS AND DISCUSSION

GLP-1 RAs have an established efficacy and safety profile. Their benefits derive from their blood glucose-lowering effects, which include pancreatic beta-cell-mediated glucose-dependent insulin secretion and suppressed glucagon release, and their ability to slow gastric emptying and promote satiety. GLP-1 RAs may also exert beneficial effects on multiple organ systems in which GLP-1 receptors are present, including the cardiovascular and renal systems. Differences between individual GLP-1 RAs with regard to their molecular size, structure and duration of action (short or longer acting) have led to differing pharmacodynamics and clinical effects such as degree of glycaemic control, weight loss abilities, cardiovascular effects and tolerability profiles.

WHAT IS NEW AND CONCLUSION

From the literature, this appears to be the first review of the evidence base supporting the MoA of once-weekly GLP-1 RAs in T2D aimed at pharmacists, with a particular emphasis on the expanding role of pharmacists in team-based diabetes management. As a class, GLP-1 RAs are an effective treatment option for people with T2D, shown to achieve multi-factorial clinical benefits. The results suggest that when selecting or advising about treatments, pharmacists should consider how the different once-weekly GLP-1 RAs and their MoA affect clinical outcomes in order to ensure optimal treatment for individuals.

Patient-Reported Outcomes with Insulin Glargine 300 U/mL in People with Type 2 Diabetes: The MAGE Multicenter Observational Study

INTRODUCTION

MAGE was a Multicenter, single-Arm, observational 6-month (plus 6-month extension) study that aimed to assess treatment satisfaction, efficacy, and safety of insulin Glargine 300 U/mL (Gla-300) in people with type 2 diabetes (T2DM) receiving basal-bolus insulin in a rEal-world setting.

MATERIALS AND METHODS

Participants were at least 18 years old, with T2DM for more than 1 year, HbA_1c 7.0-10.0%. The primary endpoint was change in Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) total score (baseline to month 6). Secondary endpoints included reasons for starting Gla-300, changes in the DTSQ change version (DTSQc) total score, Hypoglycemia Fear Survey-II (HFS-II) total behavior and worry scores at months 6 and 12, HbA_1c changes at months 3, 6, 9, and 12, and safety.

RESULTS

MAGE included 87 adults (mean T2DM duration 17 years). The primary endpoint of DTSQs mean (standard deviation) total score improvement at month 6 was achieved (2.80 [5.46] points; p < 0.0001). The main reasons for Gla-300 initiation were to decrease HbA_1c (89.7% of participants) and reduce the number of hypoglycemic events (35.6% of participants). Significant improvements were observed in the DTSQc total score and perceived hyperglycemia/hypoglycemia (baseline to month 6, p < 0.05). Significant changes in HFS-II behavior, worry, and total scores at 6 and 12 months were also observed (p < 0.05). There were no statistically significant changes in HbA_1c. Safety outcomes, including hypoglycemia, were comparable to previously reported trials.

CONCLUSIONS

The MAGE study indicates that Gla-300, as part of a basal-bolus regimen, results in improved treatment satisfaction and reduced hypoglycemia fear in people with advanced T2DM.

Diabetes care knowledge and practice among primary care physicians in Southeast Nigeria: a cross-sectional study

Background

Due to the perennial shortage of diabetes specialists, primary care physicians (PCPs) constitute the largest diabetes care manpower in Nigeria. However, the competence of the PCPs to undertake this task is not known. This study was aimed at evaluating diabetes care knowledge and practice among PCPs in Southeastern part of Nigeria.

Methods

This was a cross-sectional study among PCPs in Southeastern Nigeria. Diabetes care knowledge and practices were evaluated using a structured self administered questionnaire.

Results

A total of 64 PCPs with mean duration of practice of 17.3 ± 11.6 years completed the study. 65.6% were in private practice and 50% attended to between 11 and 20 persons living with diabetes (PLWD) weekly. Majority (78.1%) had not participated in any diabetes training since graduation from medical school and 79.9% were not aware of any diabetes clinical practice guideline.

The PCPs had adequate knowledge of classical symptoms of diabetes. However, they had very poor knowledge of glycemic thresholds for diagnosis of diabetes which was 26.6, 45.3 and 10.9% for fasting blood glucose (FBG), random blood glucose (RBG) and glycated hemoglobin (A1c) respectively.

We observed serious gaps in diabetes care practice such that only 18.8% of the respondents performed foot examination on newly diagnosed PLWD while 28.1 and 39.1% provided counseling on foot care and hypoglycemia respectively. Annual comprehensive foot examination was conducted by only 12.5%, none of the physicians ever screened for microalbuminuria and only 21.9% conducted annual dilated eye examination. Majority (57.8%) rated their confidence in prescribing insulin as “low” and only 23.4% had ever prescribed outpatient insulin for type 2 diabetes in their practice. Glycemic monitoring was largely limited to FBG and only 17.2% monitored A1c. Duration of practice more than 10 years (OR 10.1; P 0.034) and non participation in diabetes training (OR 6.5; P 0.027) were significant predictors of poor diabetes care knowledge.

Conclusion

Diabetes care knowledge and practice were poor among PCPs in Southeast Nigeria. There is an urgent need to improve their capacity to provide diabetes care through periodic training.

The effectiveness of insulin glargine 300 U/mL among type 2 diabetes patients: Analysis of a real-world data in Israel

AIMS

Randomized controlled trials have shown that insulin glargine 300 U/mL (Gla-300) has a more stable and prolonged glucose lowering effect among patients with type 2 diabetes (T2DM) compared to insulin glargine 100 U/mL (Gla-100), resulting in a reduced risk of hypoglycaemia while maintaining a similar efficacy of lowering HbA1c. We aimed to investigate if the effectiveness of Gla-300 is reproducible in real-world settings.

MATERIAL AND METHODS

In this retrospective cohort study, data from a large state-mandated health organization were used to identify adult T2DM patients who were previously on insulin and initiated Gla-300 therapy between 6/ 2016 and 12/2017. Changes in HbA1c levels, body weight and insulin dose were calculated from baseline period and over a follow-up period of 180 days. Documented hypoglycaemia events were also explored.

RESULTS

A total of 1797 patients were included in this study with a mean age of 64.2 (SD = ±11.0y), baseline HbA1c was 8.7 ± 1.6% and 42.5% were females. Among all patients with HbA1c measurement during follow-up (n = 1508), HbA1c was significantly reduced by -0.6% (95% CI -0.6,-0.5; P < .001) from baseline, with a significant reduction in body weight (-0.4 kg; P = <.001).Additionally, a significant (P = .04) reduction of 40.5% in patients with hypoglycaemia events was recorded during follow-up period, from 2.1% (n = 37) at the baseline period to 1.2% (n = 22).

CONCLUSIONS

This real-world study supports evidence from RCTs regarding the effectiveness of Gla-300 among T2DM patients by improving glycaemic control.

Relationship between hypoglycaemia, body mass index and quality of life among patients with type 1 diabetes: Observations from the DEPICT clinical trial programme

AIMS

To demonstrate the relationships between hypoglycaemia, body mass index (BMI) and quality of life, and to examine the impact of dapagliflozin on patient-reported treatment satisfaction in patients with type 1 diabetes mellitus (T1DM), using data from the DEPICT (Dapagliflozin Evaluation in Patients With Inadequately Controlled Type 1 Diabetes) clinical trial programme.

METHODS

A two-stage modelling approach, using a linear regression framework, was adopted to evaluate the relationship between hypoglycaemia, BMI and quality of life. Hypoglycaemia fear score (HFS) was modelled as a function of hypoglycaemic events (non-severe documented symptomatic and severe) and, subsequently, quality of life (as measured by the EQ-5D questionnaire) was modelled as a function of HFS and BMI. A linked evidence approach correlated the relationship between treatment, hypoglycaemic events and glycated haemoglobin (HbA1c), to the relationships captured within the regression models. The proportion of patients achieving increased patient-reported treatment satisfaction, as measured by the Diabetes Treatment Satisfaction Questionnaire (DTSQ) total score, was compared between study arms.

RESULTS

Incident severe hypoglycaemia was associated with significantly higher HFS (coefficient estimate [CE] 14.62, P=0.004). The frequency of symptomatic hypoglycaemic events was associated with a significantly higher HFS (log transposed, CE 1.32, P=0.026). Higher HFS and higher BMI were both independently associated with a significantly lower EQ-5D score (HFS: CE -0.0024, P<0.001; BMI: CE -0.0026, P=0.016). Significantly higher proportions of dapagliflozin-treated patients achieved ≥3-point increases in DTSQ total score compared to patients in the placebo group.

CONCLUSION

The results of this study demonstrated that increases in hypoglycaemia and BMI were associated with reduced quality of life in people with T1DM. Dapagliflozin-treated patients achieved a reduction in HbA1c whilst avoiding an increase in hypoglycaemic events. The results also showed that treatment with dapagliflozin was associated with an improvement in treatment satisfaction.

Factors associated with quality of life in patients with diabetic hypoglycaemia

AIMS AND OBJECTIVES

To identify determinants of quality of life among patients who had experienced hypoglycaemia and who were undergoing insulin treatment.

BACKGROUND

Patients with diabetes receiving insulin treatment are at high risk for hypoglycaemia, which tends to affect their quality of life.

DESIGN

With a cross-sectional and observational study design (see the STROBE checklist and Appendix S1).

METHODS

One hundred and fifty patients with type 2 diabetes who had received insulin treatment and had experienced hypoglycaemia (<70 mg/dl) in the last 6 months were recruited. Data were collected from May 2016-February 2018 using the Knowledge of Hypoglycaemia Scale, Fear of Hypoglycaemia Scale, Social Support Scale and the simplified Taiwanese version of the Quality of Life Scale developed by the World Health Organization.

RESULTS

Factors found to be associated with quality of life in patients with hypoglycaemia included having an educational level of senior high school or above, being on an insulin regimen only, engaging in regular exercise, diabetes complications, fear of hypoglycaemia and greater social support, which accounted for 28.5% of the total variance.

CONCLUSIONS

During the process of glycaemic control, patients inevitably experience hypoglycaemic episodes. Therefore, healthcare providers should assist patients with disease management to improve their quality of life. Future studies should also recruit patients who claim to have experienced hypoglycaemic symptoms, rather than considering only those with blood glucose levels below 70 mg/dl, to expand the generalisability of the findings. Future studies may also focus on the management of hypoglycaemia in patients on an insulin regimen, and on examining the effect of health education programmes on prevention of hypoglycaemia.

RELEVANCE TO CLINICAL PRACTICE

The present findings could provide a reference for healthcare providers to consolidate nursing care guidelines and to improve such patients' quality of life.

The translational network for metabolic disease - from protein interaction to disease co-occurrence

Background

The recent advances in human disease network have provided insights into establishing the relationships between the genotypes and phenotypes of diseases. In spite of the great progress, it yet remains as only a map of topologies between diseases, but not being able to be a pragmatic diagnostic/prognostic tool in medicine. It can further evolve from a map to a translational tool if it equips with a function of scoring that measures the likelihoods of the association between diseases. Then, a physician, when practicing on a patient, can suggest several diseases that are highly likely to co-occur with a primary disease according to the scores. In this study, we propose a method of implementing ‘n-of-1 utility’ (n potential diseases of one patient) to human disease network—the translational disease network.

Results

We first construct a disease network by introducing the notion of walk in graph theory to protein-protein interaction network, and then provide a scoring algorithm quantifying the likelihoods of disease co-occurrence given a primary disease. Metabolic diseases, that are highly prevalent but have found only a few associations in previous studies, are chosen as entries of the network.

Conclusions

The proposed method substantially increased connectivity between metabolic diseases and provided scores of co-occurring diseases. The increase in connectivity turned the disease network info-richer. The result lifted the AUC of random guessing up to 0.72 and appeared to be concordant with the existing literatures on disease comorbidity.

Hypoglycaemia and treatment patterns among insulin-treated patients with type 2 diabetes who switched to insulin glargine 300 units/mL versus other basal insulin in a real-world setting

INTRODUCTION

Type 2 diabetes (T2D) is characterized by worsening pancreatic β-cell function often requiring treatment escalation with oral antidiabetic drugs (OADs), glucagon-like peptide-1 and eventually insulin. Although there is much evidence available on the initiation of basal insulins, fewer studies have investigated the effects of switching from one basal insulin to another. This study aims to evaluate treatment persistence and hypoglycaemia in adult patients with T2D on prior basal insulin who were switched to insulin glargine 300 units/mL (Gla-300) or other basal insulins in a real-world setting.

MATERIALS AND METHODS

This study is a retrospective cohort analysis of patient-level data extracted from the Optum® Clinformatics™ database between 1 October 2014 and 30 June 2016. Adult patients (≥18 years) with T2D who were being treated with basal insulin during the 6-month baseline period, who switched to either Gla-300 or other basal insulins, were followed up for ≥3 months after switching. Outcomes included treatment persistence, and incidence and number of hypoglycaemic events.

RESULTS

Of the included patients, 1204 switched to Gla-300 and 616 switched to other basal insulins. Adjusting for baseline confounders, patients who switched to Gla-300 were 34% less likely to discontinue their basal insulin than patients who switched to other basal insulins (hazard ratio [HR] 0.66; 95% confidence interval [CI] 0.54-0.81; P < 0.001). Patients who switched to Gla-300 were less likely to experience hypoglycaemia at 3-month follow-up (odds ratio [OR] 0.56, 95% CI 0.32-0.97; P = 0.039) and at 6-month follow-up (OR 0.58, 95% CI 0.38-0.87; P = 0.009) compared with patients who switched to other basal insulins.

CONCLUSIONS

Patients with T2D on prior basal insulin in a real-world setting who switched to Gla-300 were more persistent with their basal insulin and experienced less hypoglycaemia than patients who switched to other basal insulins.

Impact of Pharmacist Intervention on Improving the Quality of Life of Patients with Type 2 Diabetes Mellitus

AIM

To analyse the characteristics, and analyse the impact of pharmacist intervention on quality of life (QOL) outpatients with type 2 diabetes mellitus (T2DM).

METHODS

This six-month analytical cohort study was conducted by assessing the patients' characteristics and their quality of life by distributing a questionnaire, and the 36-Item short form instrument to the patients with T2DM (n = 45) admitted to the Tertiary hospital in Tebing Tinggi. Patients who had mental disorders, HIV-AIDS, liver disease, stage 4 chronic kidney disease, and pregnant women were excluded from the study. The patients' quality of life was measured before and after interventions and analysed using the paired t-test. All analyses were performed using the Statistical Package for the Social Sciences (SPSS, version 22, Chicago, IL, USA) (p < 0.05 was considered significant).

RESULTS

The mean age of the patients was 61.96 ± 6.45 (years). Most (66.7%) of them were females. The mean QOL (in the score) of the patients: before the intervention, 61.07 ± 15.13; after the intervention, 70.15 ± 14.23, there was a significant difference between groups with and without interventions, p < 0.001.

CONCLUSION

Active contribution of pharmacists in the management of T2DM patients is urgent and important to improve the patients' QOL.

Hypoglycaemia Among Insulin-Treated Patients with Diabetes: Evaluation of the United Arab Emirates cohort of the International Operations-Hypoglycaemia Assessment Tool study

Objectives

This study aimed to evaluate the incidence of hypoglycaemia among insulin-treated patients with type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) from the United Arab Emirates (UAE) cohort of the non-interventional International Operations-Hypoglycaemia Assessment Tool study.

Methods

This cross-sectional observational study took place at 25 patient care centres in the UAE from October 2014 to May 2015. All adult patients with T1DM or T2DM who had been treated with insulin for >12 months were included. Self-assessment questionnaires and patient diaries were used to determine the incidence of documented hypoglycaemia both prospectively (four weeks after baseline) and retrospectively (six months and four weeks before baseline for severe and non-severe hypoglycaemic events, respectively).

Results

A total of 325 patients were enrolled in the study, of which 82 (25.2%) had T1DM and 243 (74.8%) had T2DM. Among patients with T1DM, 71.4% reported hypoglycaemic events retrospectively, with an incidence rate (IR) of 102.8 events per patient-year (PY), while 95% reported hypoglycaemic events prospectively, with an IR of 63.1 events per PY. Additionally, 56.3% of patients with T2DM reported hypoglycaemic events retrospectively, with an IR of 42.2 events per PY, while 91.9% reported hypoglycaemic events prospectively, with an IR of 33.3 events per PY.

Conclusion

The prevalence and incidence of hypoglycaemia were high among insulin-treated patients with T1DM and T2DM in the UAE. Individualised glycaemic goals, patient education and blood glucose monitoring may help to reduce the incidence of hypoglycaemia in this population.

Comparison of the HAT study, the largest global hypoglycaemia study to date, with similar large real-world studies

AIMS

Optimal diabetes care requires clear understanding of the incidence of hypoglycaemia in real-world clinical practice. Current data on hypoglycaemia are generally limited to those reported from randomised controlled clinical trials. The Hypoglycaemia Assessment Tool (HAT) study, a non-interventional real-world study of hypoglycaemia, assessed hypoglycaemia in 27 585 individuals across 24 countries. The present study compared the incidence of hypoglycaemia from the HAT study with other similarly designed, large, real-world studies.

MATERIALS AND METHODS

A literature search of PubMed (1995-2017) for population-based studies of insulin-treated patients with type 1 or type 2 diabetes (T1D, T2D), excluding clinical trials and reviews, identified comparable population-based studies reporting the incidence of hypoglycaemia.

RESULTS

The 24 comparative studies, including more than 24 000 participants with T1D and more than 160 000 participants with T2D, varied in design, size, inclusion criteria, definitions of hypoglycaemia and method of recording hypoglycaemia. Reported rates (events per patient-year [PPY]) of hypoglycaemia were higher in patients with T1D than in those with T2D (overall T1D, 21.8-73.3 and T2D, 1.3-37.7; mild/non-severe T1D, 29.0-126.7 and T2D, 1.3-41.5; severe T1D, 0.7-5.8 and T2D, 0.0-2.5; nocturnal T1D, 2.6-11.3 and T2D, 0.38-9.7) and were similar to the ranges found in the HAT study.

CONCLUSIONS

The HAT data on hypoglycaemia incidence were comparable with those from other real-world studies and indicate a high incidence of hypoglycaemia among insulin-treated patients. Differences in rates among studies are mostly explained by differences in patient populations and study methodology. The goal of reducing hypoglycaemia should be a target for continued educational and evidence-based pharmacological interventions.

Lack of Treatment Persistence and Treatment Nonadherence as Barriers to Glycaemic Control in Patients with Type 2 Diabetes

Treatment persistence (continuing to take medication for the prescribed period) and treatment adherence (complying with the prescription in terms of drug schedules and dosage) are both important when treating chronic diseases such as type 2 diabetes (T2D). They can be indicators of patient satisfaction with treatment. In T2D, the achievement of optimal outcomes requires both persistence with and adherence to prescribed therapy. Poor persistence with and adherence to T2D medication can have profound consequences for the patient, including non-achievement of glycaemic goals and an increased risk of long-term complications and mortality. Therefore, poor treatment persistence and adherence may also have economic consequences, including increased healthcare resource utilization and healthcare costs. Treatment persistence and adherence are affected by several factors, including the mode of administration, administration frequency/regimen complexity, and patient expectations. The aims of this review are as follows: to provide an overview of persistence with and adherence to different antidiabetes therapies for patients with T2D in the real-world setting; examine factors contributing to poor treatment persistence and adherence; and assess available data on the impact of poor treatment persistence and/or adherence on clinical and economic outcomes. Numerous potential targets for improving treatment persistence and/or adherence are identified, including developing less complex treatment regimens with lower pill burdens or less frequent injections, improving the convenience of drug-delivery systems, such as the use of insulin pen devices rather than the conventional vial and syringe, and developing therapies with an improved safety profile to alleviate patient fears of adverse effects, such as weight gain and risk of hypoglycaemia.Funding: Sanofi.

Humanistic and economic burden of cardiovascular disease related comorbidities and hypoglycaemia among patients with type 2 diabetes in Japan

AIM

This study aims to examine the humanistic and economic burden of cardiovascular disease (CVD)-related comorbidities and hypoglycaemia among respondents with type 2 diabetes (T2D) in Japan.

METHODS

This study used the Japan National Health and Wellness Survey 2016 database. Respondents who self-reported a physician-diagnosed T2D were included. Respondents with or without the condition of interest (CVD-related comorbidities or hypoglycaemia) were compared via generalized linear models in terms of the outcome variables: (1) health-related quality of life (HRQoL), (2) work productivity and activity impairment, (3) healthcare resource utilization and (4) economic costs.

RESULTS

A total of 1478 survey respondents reported a diagnosis of T2D (mean age 63.6 ± 10.6 years, mean HbA1c 6.91 ± 1.1%). Of whom, 804 subjects (54.4%) had at least one CVD related comorbidities, and 369 subjects (29.3%) reported experiences of hypoglycaemia episodes. Patients with CVD-related comorbidities or hypoglycaemia episodes had worse HRQoL, more work and activity impairment, increased health care visits, and higher costs.

CONCLUSIONS

CVD related comorbidities and hypoglycaemia remains a significant humanistic and economic burden in patients with T2D. The findings suggested that appropriate T2D management with proper medication choice are important to control CVD related comorbidities and hypoglycaemia among T2D patients to alleviate the burden.

Factors of occurrence and improvement methods of presenteeism attributed to diabetes: A systematic review

Objective

A systematic review was performed to study factors of occurrence and improvement methods of presenteeism attributed to diabetes.

Methods

We set 2 clinical questions; (a) how comorbidities and complications of diabetes induce presenteeism and (b) what interventions or conditions effectively improve presenteeism. Then, we conducted a comprehensive search with MEDLINE/PubMed and Scopus databases and extracted those that met the clinical questions.

Results

Eighteen papers studied occurrence of presenteeism by comorbidities and complications of diabetes. Most studies were cross‐sectional and had a low quality of evidence. However, the associations of hypoglycemia, diabetic neuropathy, and mood disorders with presenteeism were relatively well studied. The papers that discussed effective interventions or conditions for improving presenteeism were very limited.

Conclusions

Our review suggests that presenteeism attributed to diabetes is mainly caused by hypoglycemia, diabetic neuropathy, and mood disorders. There are very limited evidences, but available information suggests that improving glycemic control, adjusting treatment regimen by evaluating the impact on work, providing psychological support, and developing suitable work accommodations may effectively reduce presenteeism.

Association of Depressive Symptoms and Diabetes Distress With Severe Hypoglycemia in Adults With Type 2 Diabetes

OBJECTIVES

To examine the association of depressive symptoms (DS) and diabetes-related distress (DD) with severe hypoglycemia (SH) in adults with type 2 diabetes.

METHODS

Baseline data from a cohort study of adults with type 2 diabetes (N=2,040) were used. The Patient Health Questionnaire 8-items and Problem Areas in Diabetes 5-items questionnaires were used to assess DS and DD, respectively. SH was defined as a positive report of "calling an ambulance or visiting an emergency department because of hypoglycemia in the past year." Composite dummy variables for the 2 stratification levels of DS and DD were computed and used in multivariable logistic regression analyses.

RESULTS

Participants had a mean (± SD) age of 64±11 years, and 45% were female. The average duration of diabetes was 12±9 years; 3% had moderate to severe DS, 8% had moderate to severe DD and 5% had moderate to severe levels of both symptoms. Only 4.2% of participants reported experiencing SH in the past year. The presence of any level of DD (adjusted OR 2.3; 95% CI 1.3, 3.9) or moderate to severe DD (2.2; 1.1, 4.2) was associated with increased risk for SH. Combinations of any levels of DD and DS (4.3; 2.5, 7.3) and moderate to severe DD and DS (2.3; 1.1, 4.8) were associated with increased risk for SH. The presence of any level of DS alone (1.2; 0.3, 4.9) or moderate to severe DS (1.7; 0.6, 5.1) was not associated with increased risk for SH.

CONCLUSIONS

Patients with type 2 diabetes and symptoms of depression, but not diabetes-related distress alone, were more likely to experience SH than those without either of these symptoms.

Burden of Illness in Type 2 Diabetes Mellitus

An estimated 30.2 million Americans have diabetes, and this number is expected to increase based on trends over recent decades and compounded by an aging U.S.

POPULATION

As reviewed in this article, type 2 diabetes mellitus (T2DM) is associated with impaired health-related quality of life (HRQoL) and with a substantial socioeconomic burden. Compared with individuals without T2DM, those with T2DM have worse HRQoL, greater decrements in HRQoL over time, and possibly greater depressive symptomology. Diabetes-related complications and comorbidities (e.g., obesity and cardiovascular disease) are associated with worse HRQoL. Hypoglycemic episodes are associated with reduced HRQoL and greater levels of depression; they can also interfere with social and occupational activities. In turn, low HRQoL can be a driver for poor glycemic control. In 2012, the total estimated cost associated with diagnosed diabetes in the United States was $245 billion. Factors contributing to increased health care resource utilization and costs in patients with T2DM include medical comorbidities, diabetes-related complications, inadequate glycemic control, and hypoglycemic episodes. Readmission is a key driver of hospital-related costs and is more common among elderly patients with T2DM. Elderly patients with T2DM represent a particularly vulnerable population given that these patients may have varying degrees of physical and mental comorbidities that can increase their risk of hypoglycemia, falls, and depression. This review demonstrates that T2DM imposes a considerable burden on both the individual and society. Treatment strategies should consider the effects of treatment on HRQoL and on outcomes (e.g., complications and hypoglycemia) that affect both HRQoL and costs. Management strategies that maximize HRQoL while minimizing the risk of hypoglycemia and other treatment-related complications are particularly critical in the elderly.

Efficacy and Safety of Sitagliptin in Hispanic/Latino Patients with Type 2 Diabetes: A Pooled Analysis from Ten Randomized, Placebo-Controlled Phase 3 Clinical Trials

INTRODUCTION

To assess the efficacy and safety profile of the dipeptidyl-peptidase-4 inhibitor sitagliptin in a population of self-identified Hispanic/Latino patients with type 2 diabetes.

METHODS

Data were pooled from ten randomized, double-blind studies in which subjects were treated with sitagliptin 100 mg/day (as mono- or combination therapy) or placebo, and used to evaluate the glycemic efficacy, safety, and tolerability of sitagliptin compared with placebo after 24 weeks of treatment.

RESULTS

A total of 804 Hispanic/Latino patients were included in the analysis. Baseline characteristics in the treatment groups were similar (mean baseline HbA1c of approximately 8.5%). The LS mean HbA1c changes from baseline were - 0.94% with sitagliptin and - 0.32% with placebo, and the between-group difference was - 0.62%, p < 0.001. After 24 weeks of treatment, 35% and 18% of subjects were at the HbA1c goal of < 7% in the sitagliptin and placebo groups, respectively. Body weight increased slightly in both treatment groups. Incidences of adverse events of hypoglycemia were similar and low (1.9% and 1.4% for sitagliptin and placebo, respectively) in both groups in studies in which insulin or sulfonylurea were not used and were similar (9% and 11% for sitagliptin and placebo, respectively) when all studies were included. Overall safety and tolerability of treatment with sitagliptin and placebo were similar. No clinically meaningful differences between the safety profile of sitagliptin in the Hispanic/Latino population analyzed here and broader populations previously evaluated were observed.

CONCLUSION

In this pooled analysis of sitagliptin therapy vs placebo in Hispanic/Latino patients, sitagliptin provided significant improvement in glycemic control and was generally well tolerated.

Dapagliflozin as add-on therapy in Asian patients with type 2 diabetes inadequately controlled on insulin with or without oral antihyperglycemic drugs: A randomized controlled trial

BACKGROUND

This 24-week Phase 3 double-blind placebo-controlled study assessed the safety and efficacy of dapagliflozin as add-on to insulin, with or without oral antihyperglycemic drugs (OADs), in Asian patients with inadequately controlled type 2 diabetes mellitus.

METHODS

Adult patients with HbA1c between ≥7.5% and ≤10.5%, body mass index ≤45 kg/m2 , and on insulin doses ≥20 IU daily were randomized to dapagliflozin 10 mg (n = 139) or placebo (n = 133) to assess 24-week changes in HbA1c (primary outcome), fasting plasma glucose (FPG), body weight, total daily dose of insulin (TDDI), and seated systolic blood pressure (SeSBP; exploratory outcome).

RESULTS

Baseline characteristics were similar in both groups. At Week 24, compared with placebo, dapagliflozin significantly improved HbA1c (mean [95% confidence interval] 0.03% [-0.11, 0.17] for placebo vs -0.87% [-1.00, -0.74] for dapagliflozin; between-group difference - 0.90% [-1.09, -0.71], P < 0.0001]), FPG, body weight, TDDI, and SeSBP. The incidence of adverse events (AEs) in the dapagliflozin and placebo groups was 80.5% and 71.2%, respectively, with few patients discontinuing due to AEs (dapagliflozin, 2.2%; placebo, 4.2%). The occurrence of hypoglycemia was similar in the dapagliflozin and placebo groups (23.7% and 22.6%, respectively; no major events). The frequency of urinary tract and genital infections was low; no deaths were reported.

CONCLUSIONS

Dapagliflozin as add-on to insulin, with or without OADs, significantly improved glycemic control and reduced body weight and blood pressure in Asian patients. Dapagliflozin was well tolerated, with a similar frequency of hypoglycemia in both groups. These results support the use of dapagliflozin as add-on to insulin, with or without OADs, in this population.

Hypoglycemia in type 2 diabetes: understanding patients' and physicians' knowledge and experience

PURPOSE

The aim of the current study is to assess the patient and physician experience and knowledge of hypoglycemia in the management of type 2 diabetes (T2DM).

METHODS

T2DM patients (N = 1002) completed questionnaires on hypoglycemia experience, familiarity, and fear. Their responses were compared across various antihyperglycemic treatment regimens; specifically, (1) insulin only or insulin combined with sulfonylurea [SU] and/or metformin, (2) SU only with/without metformin, and (3) neither insulin nor SU. Physicians (N = 1003) completed questionnaires on hypoglycemia knowledge and decision-making, and their responses were compared by specialty [75% primary care providers (PCPs) and 25% endocrinologists].

RESULTS

T2DM patients treated with, (1) insulin only, or (2) insulin plus SU or metformin, reported the most experience and familiarity with-but also fear of-hypoglycemic events. Insulin-treated patients (insulin alone or insulin plus SU/metformin) also reported experiencing more hypoglycemia (all p-values <0.012). For physicians, endocrinology specialty was significantly associated with higher hypoglycemia knowledge scores (all p-values <.001). Irrespective of specialty, physician hypoglycemia knowledge, in turn, was associated with correct treatment decision-making (all p-values <0.001).

CONCLUSIONS

Insulin-based antihyperglycemic regimens were associated with high prevalence, severity, familiarity, and fear of hypoglycemia. An effective strategy to mitigate the burden of hypoglycemia may be to optimize pharmacological therapy to prevent these events. Since physician hypoglycemia knowledge was highly correlated to correct therapeutic decision-making, continued physician education regarding this acute complication of diabetes treatment should be prioritized for those managing patients with T2DM.

Impact of the severity of hypoglycemia on health - Related quality of life, productivity, resource use, and costs among US patients with type 2 diabetes

AIMS

To explore the association between hypoglycemia severity and health-related quality of life (HRQoL), productivity, health care resource utilization (HCRU), and costs among patients with type 2 diabetes mellitus (T2DM).

METHODS

Data were from the 2013 US National Health and Wellness Survey. This analysis included adults with treated T2DM. Participants were categorized based upon their self-reported experience in the previous 3 months: no hypoglycemia, non-severe hypoglycemia, or severe hypoglycemia. Validated instruments were used to measure HRQoL and productivity; HCRU was based on participant-reported health care provider (HCP) and emergency department (ED) visits and hospitalizations. Multivariable models tested for trends across the severity groups.

RESULTS

The analysis included 3630 participants-1729 (47.6%) with non-severe hypoglycemia and 172 (4.7%) with severe hypoglycemia. Mental and physical component scores and utility scores were significantly associated with hypoglycemia severity (P < 0.001 for each). Similar trends were observed for absenteeism (P < 0.001), presenteeism (P = 0.005), HCP and ED visits (P ≤ 0.002), and hospitalizations (P < 0.001). Annual HCRU costs associated with increasingly severe hypoglycemia were $6908, $7132, and $15,410, respectively (P < 0.001), and productivity costs were $7248, $7493, and $12,167, respectively (P = 0.008).

CONCLUSION

Hypoglycemia severity appears to be related to reduced HRQoL and productivity, which are mirrored by increased direct and indirect costs.

Perspectives of Patients with Insulin-Treated Type 1 and Type 2 Diabetes on Hypoglycemia: Results of the HAT Observational Study in Central and Eastern European Countries

INTRODUCTION

The aim of this study was to determine the level of awareness of hypoglycemia, the level of fear for hypoglycemia, and the response to hypoglycemic events among insulin-treated diabetes patients from Central and Eastern Europe (CEE). The impact of hypoglycemia on the use of healthcare resources and patient productivity was also assessed.

METHODS

This was a multicenter, non-interventional, two-part, patient self-reported questionnaire study that comprised both a retrospective cross-sectional evaluation and a prospective observational evaluation. Study participants were insulin-treated adult patients with type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) from CEE.

RESULTS

Most patients (85.4% T1DM and 83.6% T2DM) reported normal hypoglycemia awareness. The median hypoglycemia fear score was 5 out of 10 for T1DM and 4 out of 10 for T2DM patients. Patients increased glucose monitoring, consulted a doctor/nurse, and/or reduced the insulin dose in response to hypoglycemia. As a consequence of hypoglycemia, patients took leave from work/studies or arrived late and/or left early. Hospitalization was required for 31 (1.2%) patients with T1DM and 66 (2.1%) patients with T2DM.

CONCLUSION

Hypoglycemia impacts patients' personal and social functioning, reduces productivity, and results in additional costs, both direct (related to increased use of healthcare resources) and indirect (related to absenteeism.

Impact of hypoglycemic episodes on health-related quality of life of type-2 diabetes mellitus patients: development and validation of a specific QoLHYPO© questionnaire

Background

Hypoglycemia is a limiting factor to achieving optimal glycemic control in patients with type-2 diabetes mellitus (T2DM), increasing risk of death and complications, reducing health-related quality of life (HRQoL) and work productivity and increasing healthcare costs.

The study’s primary objective was to develop and validate a specific questionnaire to assess the impact of hypoglycemia on the HRQoL of T2DM patients (QoLHYPO^© questionnaire).

Methods

A two-phase multicenter prospective, longitudinal, observational, epidemiologic study of consecutively enrolled patients, not involving any drug, was conducted: In phase 1 (questionnaire development), patients who had given their written informed consent, who were at least 30 years of age, had been diagnosed with T2DM at least 5 years prior, had an HbA1c test in the previous 3 months, and a hypoglycemic episode in the previous 6 months were included. To validate the questionnaire and assess reliability and responsiveness, phase 2 included two cohorts of patients. Patients in the reliability cohort would likely have stable clinical course during the 3 weeks following inclusion in the study and patients in the responsiveness cohort would likely experience changes in their clinical course in the 3 months after enrollment.

Results

Phase 1 included 168 patients: 10 attended semi-structured interviews, 18 for face validity, and 140 for the pilot test (Rasch analysis). Phase 2 included 227 patients: 142 in the reliability cohort and 85 in the responsiveness cohort.

Of the 37 items initially included in Phase 1, 11 (floor/ceiling effect analysis) and 13 (Rasch analysis) were discarded. The final version of the questionnaire consisted of 13 items.

Phase 2 results showed the questionnaire was unidimensional and able to accurately assess HRQoL. Intra-observer reproducibility (ICC = 0.920) and internal consistency (Cronbach’s alpha: visit 1 = 0.912; visit 2 = 0.901) were high, showing high reliability. Internal responsiveness was moderate (standardized effect size 0.5-0.8) and external responsiveness was lower (AUC > 0.5; not statistically significant). Minimal clinically important difference (MCID) was estimated to be 3.2 points.

Conclusions

The QoLHYPO^© questionnaire is a tool that can be used in routine clinical practice to assess the impact of hypoglycemia on the HRQoL of T2DM patients.

Impact of a Novel Insulin Management Service on Non-insulin Pharmaceutical Expenses

BACKGROUND

Studies have shown that improvements in glycemic control are associated with avoidance or delayed onset of diabetes complications, improvements in health-related quality of life, and reductions in diabetes-related health care costs. Clinical practice guidelines recommend maintaining a hemoglobin A1c (HbA1c) level less than 7%, but among type 2 diabetes patients using insulin, two-thirds have HbA1c above 7% and one-third have HbA1c above 9%.

OBJECTIVES

This study examined the use of insulin management services to enable patients to optimize insulin dosing to achieve HbA1c targets and subsequently reduce health care costs. Cost savings may be achieved through reduced complications and hospitalizations, as well as reduced outpatient, physician, and clinic costs. This study quantified the reduction in pharmaceutical expenses related to the use of an enhanced insulin management service to improve glycemic control.

METHODS

Two hundred seventeen insulin-reliant patients were enrolled in the d-Nav® Insulin Guidance Service through a participating insurance group. A prospective cost analysis was conducted using data from enrolled patients who completed the first 90 days of follow up.

RESULTS

Of the 192 patients who completed the 90-day study period, 54 (28.13%) were prescribed one or more expensive medications at baseline, but 45 (83.33%) of those patients were eligible for medication discontinuation after 90 days. At baseline, the annual cost of expensive medications per patient was $7564 (CI: $5191-$9938) and $1483 (CI: -$1463-$4429) at 90 days (p<0.001). Direct savings from medication elimination was estimated to be $145 per patient per month (PPPM) or $1736 per patient per year (PPPY) for all patients and $514 PPPM/$6172 PPPY for the target group. Patients that completed the 90-day period significantly reduced HbA1c levels from 9.37% (CI:7.72%-11.03%) at baseline to 7.71% (CI: 6.70%-8.73%) (p<0.001). A total of 170 (88.54%) patients had improved HbA1c at 90 days.

CONCLUSIONS

Use of the insulin guidance service achieved improved glycemic control by optimizing insulin dosing, which enabled most patients using the service to reduce or eliminate the use of expensive diabetes medications. Further study is needed to assess the impact of optimized insulin dosing on other diabetes-related health care costs in a usual practice setting.

Severity of hypoglycaemia and health-related quality of life, work productivity and healthcare costs in patients with type 2 diabetes in Europe

Aims

Hypoglycaemia in patients with type 2 diabetes mellitus (T2DM) is associated with poor health outcomes, such as reduced health‐related quality of life (HRQoL). This study aimed to assess the impact of hypoglycaemic events by severity on HRQoL, work productivity and healthcare costs in patients with T2DM.

Materials and Methods

European patients with T2DM selected from the National Health and Wellness Survey who were currently receiving pharmacologic therapy were stratified into 3 groups based on the reported history and severity of hypoglycaemic events (no event, nonsevere, severe) experienced in the previous 3 months. Patients’ work productivity, HRQoL, healthcare resource use (HCRU) and associated costs were assessed as self‐reported outcomes.

Results

Of 1269 patients included in the study, 652 (51.4%) patients had not experienced an event, while 533 (42.0%) and 84 (6.6%) patients had experienced nonsevere and severe hypoglycaemic events, respectively, in the previous 3 months. An increase in hypoglycaemia severity was associated with a decrease in HRQoL, and an increase in HCRU and healthcare costs.

Conclusions

The impact of hypoglycaemia varies by severity and has a negative impact on HRQoL and overall HCRU and costs.

Factors Associated With Medication Engagement Among Older Adults With Diabetes: Systematic Review and Meta-Analysis

Purpose

The purpose of this systematic review and meta-analysis is to explore the factors associated with medication engagement among older adults (≥60 years) with diabetes.

Methods

Five databases (PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and Scopus) were systematically searched to identify studies examining the association between factors and medication engagement among older diabetes patients. A study met inclusion for meta-analysis if the prevalence of medication engagement or factor was reported in ≥2 studies and the frequency or strength of association was either reported or able to be computed. Quality appraisal was performed with the Downs and Black tool.

Results

Of 538 retrieved studies, 33 (20 cohort and 13 cross-sectional) were included for systematic review; of these, 22 met criteria for meta-analysis. Findings from meta-analysis show that women (odds ratio [OR], 0.92; 95% CI, 0.86-0.97), those with depression (OR, 0.73; 95% CI, 0.62-0.87), and those with higher out-of-pocket spending for prescription drugs (OR, 0.87; 95% CI, 0.80-0.94) were less likely to take diabetes medication when compared with men, those without depression, and those with lower out-of-pocket costs, respectively. Older age (OR, 1.13; 95% CI, 1.00-1.27) was associated with better engagement to diabetes medication.

Conclusions

Of 4 identified factors, 2 are modifiable. Recent policy efforts to decrease the cost burden of prescribed medication for older adults, such as Medicare Part D, may remove this barrier to medication engagement. Routine screening for depression among older adults with diabetes should be included as part of usual care to facilitate an integrated treatment approach.

Timing of Insulin Injections, Adherence, and Glycemic Control in a Multinational Sample of People with Type 2 Diabetes: A Cross-Sectional Analysis

INTRODUCTION

We investigated the association of bolus insulin dose timing with demographics, adherence, diabetes education program participation, experience with hypoglycemic events, glycemic control, and patient preference among respondents with type 2 diabetes.

METHODS

Adults with type 2 diabetes from 12 countries were recruited to a Web-based self-reported patient preference survey. Adherence was measured using an adapted Morisky Medication Adherence Scale questionnaire.

RESULTS

In total 1483 respondents reported using bolus insulin with 58% (n = 864) dosing bolus insulin before meals (pre-meal cohort), 354 (24%) during or after meals (post-meal cohort), and 265 (18%) before, during, or after meals (mixed cohort). The mixed cohort was excluded, thus 1218 respondents were included in the analysis. Respondent distribution across HbA_1c category differed significantly depending on insulin dose timing (p = 0.0006); more respondents in the post-meal cohort (40%) had HbA_1c ≥ 9% (74.9 mmol/mol) than in the pre-meal cohort (29%). The post-meal cohort was significantly more likely to report non-adherence than the pre-meal cohort (OR = 1.50, p = 0.01) and significantly more often reported participating in diabetes education programs (p < 0.05). Seventy-eight percent of all respondents reported preferring bolus insulin administrable whenever convenient.

CONCLUSIONS

Approximately 24% of respondents never comply with guidelines for insulin dose timing, with higher risk of non-adherence and increased participation in diabetes care programs. Respondents dosing insulin post-meal are more likely to have poor glycemic control (HbA_1c ≥ 9%, 74.9 mmol/mol). Given that many respondents had high HbA_1c and were non-adherent, a treatment which satisfies patient preference for bolus insulin with flexible dose timing could be considered.

Economic and social impact of diabetes mellitus in a low-income country: A case-control study in Sudan

BACKGROUND

Diabetes mellitus accounts for 11% of total health expenditure worldwide, and most people with diabetes live in low- and middle-income countries. The present study examined the economic and social effects attributed to diabetes in Sudan by calculating out-of-pocket medical expenses and the health and social effects of the disease for people with diabetes (n = 375) and their families compared with a non-diabetic control group (n = 375), matched for age, sex, and residence area.

METHODS

Data were obtained in 2013 in four states within the Sudan, via structured interviews, using instruments from the International Diabetes Federation. Descriptive statistics were used to analyze differences between case and control participants.

RESULTS

The median total annual medical expenditure was fourfold higher for people with than without diabetes (US$579 vs US$148, respectively). Annual mean expenditure was 85% higher for those with diabetes (US$1004 vs US$544). People with diabetes were also significantly more likely to suffer from serious comorbidities, such as cardiovascular disorders and foot ulcers, compared with control participants. Moreover, those with diabetes reported a higher proportion of personal adverse social effects, such as being prevented from doing paid work or participating in education, both for themselves and their families.

CONCLUSIONS

The high economic burden and adverse social effects on people with diabetes and their families in Sudan call for the development of evidence-based policy and program strategies for the prevention and management of diabetes, with an emphasis on low-resource communities.

Changes in glucose-lowering drug use before and after cancer diagnosis in patients with diabetes

AIM

This study explores the changes in glucose-lowering drug (GLD) use before and after cancer diagnosis among patients with diabetes.

METHODS

New GLD users (1998-2011) living in the Dutch ECR-PHARMO catchment area were selected from the PHARMO Database Network (n=52,228). Those with a primary cancer diagnosis were considered cases (n=3281) and matched with eligible controls (n=12,891) without cancer during follow-up. Conditional logistic regression analysis was used to assess changes in GLD use, such as treatment add-ons, treatments drops and initiation of insulin, for cases compared with controls associated with specific cancer types in four time windows (6-3 and 0-3months before cancer diagnosis; 0-3 and 3-6months after cancer diagnosis).

RESULTS

In the 3months before cancer diagnosis, patients with upper gastrointestinal (GI) cancers (oesophageal, stomach, pancreatic, liver cancers) had higher odds of initiating insulin (OR: 9.3; 95% CI: 3.6-24.1); to a lesser extent, this was also observed in the 3months prior to that (at 6months, OR: 3.9; 95% CI: 1.3-12.1). Diagnosis of colorectal (OR: 3.4; 95% CI: 1.4-8.4), pulmonary (OR: 2.5; 95% CI: 1.1-5.4) and upper GI (OR: 13.6; 95% CI: 5.0-36.9) cancers was associated with increased odds of initiating insulin in the 3months after cancer diagnosis. During all study time windows, the odds of treatment drops were higher for patients with upper GI cancers whereas, for most other cancers, these odds were higher only after a diagnosis of cancer.

CONCLUSION

The greater odds of initiating insulin during the 6months prior to diagnosis of upper GI cancers suggest reverse causation. After cancer diagnosis, drops in use of GLDs was commonly seen.

Combination SGLT2 inhibitor and GLP-1 receptor agonist therapy: a complementary approach to the treatment of type 2 diabetes

Among persons with type 2 diabetes (t2d), the development of glucose intolerance involves dysfunction in several organs and tissues, including the muscle, liver, pancreas, kidney, gastrointestinal tract, adipose tissue, and brain. individuals with t2d typically have a number of comorbidities, including hypertension, hyperlipidemia, and being overweight or obese, and are, consequently, at high cardiovascular risk. guidelines recommend a comprehensive care strategy that includes treatment of diabetes-related complications and comorbidities beyond those related to hyperglycemia. use of glucose-lowering therapies with complementary activities that address multiple facets of the disease may improve long-term outcomes for patients with t2d. two recent drug classes developed for use in t2d, glucagon-like peptide-1 receptor agonists (glp-1ras) and sodium glucose cotransporter 2 (sglt2) inhibitors, have been shown in clinical trials to have beneficial effects on glycemic control, body weight, cardiovascular risk factors, and (for liraglutide, semaglutide, and empagliflozin) cardiovascular outcomes, while having an acceptable safety profile. between them, these drug classes directly or indirectly affect many of the organs and tissues involved in the pathogenesis of t2d, and their beneficial effects on glycemic- and cardiovascular-related parameters are likely to be complementary and potentially additive. in the largest clinical trial of a glp-1ra and an sglt2 inhibitor in combination (duration-8), patients with t2d (n = 685) who received exenatide plus dapagliflozin added to their treatment regimen for 28 weeks had significantly greater reductions from baseline in glycated hemoglobin, body weight, and systolic blood pressure compared with patients who received either drug as monotherapy. this review summarizes the complementary aspects of these drug classes and presents the available data among patients receiving dual therapy with a glp-1ra and an sglt2 inhibitor.

Direct medical costs of severe hypoglycaemic events in patients with type 2 diabetes in England: A retrospective database study

AIMS

Hypoglycaemia in patients with diabetes can be induced by insulins and sulfonylureas. We assessed the real-world impact of specific monotherapy and combination regimens on hypoglycaemic events requiring hospitalisation and related secondary costs to the English healthcare system.

METHODS

This retrospective observational study used the Clinical Practice Research Datalink with linked hospital admission data during 2008-2012. Patients with type 2 diabetes mellitus (T2DM) using antihyperglycaemic agents (AHAs) were assigned to mutually exclusive subgroups (insulin- and non-insulin-containing regimens; treatment groups of interest; age group) based on treatment at index date (date of first AHA prescription). Outcomes were number and cost of hospital admissions with hypoglycaemic event-related diagnosis codes.

RESULTS

We identified 110 206 patients with T2DM (mean age 64.9 years, time since diagnosis 5.4 years, HbA_1c at index 7.4%), with 439 hypoglycaemic events requiring inpatient hospitalisation (mean length of stay 6.3 days, mean cost/stay £1351). Event rates and cost of stay were highest in patients treated with sulfonylurea- or insulin-based regimens. Event rates, duration and cost of stay were higher in older patients.

CONCLUSION

Rates of severe hypoglycaemic events varied substantially between T2DM regimens. In this study of patients treated in clinical practice in England, sulfonylurea- and insulin-based regimens were associated with the highest event rates and costs associated with hospitalisation for severe hypoglycaemic events; hospitalisation for severe hypoglycaemic events was not observed with dipeptidyl peptidase-4 inhibitor monotherapy or with metformin.

Behaviours, thoughts and perceptions around mealtime insulin usage and wastage among people with type 1 and type 2 diabetes mellitus: A cross-sectional survey study

AIMS

People with diabetes who use mealtime insulin (MTI) were surveyed about insulin wastage and injection habits when insufficient insulin remains in a disposable prefilled pen/cartridge to administer a full dose in a single injection.

METHODS

Cross-sectional, online, self-reported survey of MTI usage/wastage behaviour in 400 adults with type 1 (n=120) or type 2 (n=280) diabetes mellitus administering >20units/day of MTI via 100units/ml prefilled pens/cartridges for ⩾1month, conducted in France, Germany, Italy and UK.

RESULTS

Participants' mean±standard deviation age was 54.5±12.2years, body mass index was 29.9±7.2kg/m² and duration of MTI therapy was 8.6±7.8years. They administered 3.7±5.9 injections/day with meals, using 11.3±18.0 prefilled pens/cartridges per month. Overall, 63.5% split the dose across two prefilled pens/cartridges (i.e. administered two injections to obtain a full dose), 15.0% used just what remained in their current pen (i.e. took a lower-than-prescribed dose) and 36.3% discarded prefilled pens/cartridges still containing insulin (i.e. took full dose with new pen). The latter participants discarded a mean 5.5±8.2 prefilled pens/cartridges monthly still containing insulin, each containing 8.6±8.7 units of insulin. Participants who wasted insulin considered it frustrating, time-consuming and painful to inject twice.

CONCLUSIONS

Patients taking >20units/day MTI can find transitions between insulin pens challenging. This study highlights the need to identify ways of improving transitions between pens to make transitions easier for insulin users, which could potentially improve adherence to prescribed doses and reduce waste.

Hypoglycemia in patients with type 2 diabetes newly initiated on basal insulin in the US in a community setting: impact on treatment discontinuation and hospitalization

OBJECTIVE

To evaluate the impact of 6 month hypoglycemia on treatment discontinuation and hospitalization of patients initiating basal insulin for type 2 diabetes (T2D) in real-world practice.

METHODS

This was a retrospective cohort study of patient-level data using electronic medical records (EMRs) in the Predictive Health Intelligence diabetes dataset. Data from adult patients with T2D initiating basal insulin glargine, insulin detemir, or Neutral Protamine Hagedorn insulin between January 2008 and March 2014 was analyzed. The date of first basal insulin prescription in an outpatient setting was the index date. A 12 month baseline prior to the index date was established; follow-up was 6-24 months from the index date. Patients were assigned to cohorts by experience of hypoglycemia (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code or blood glucose test) in the first 6 months following the index date; with hypoglycemia and without hypoglycemia cohorts were compared for basal insulin treatment discontinuation and hospitalization.

RESULTS

Overall, 49,062 patients were included; 5159 (10.5%) experienced hypoglycemia in the 6 months following basal insulin initiation. In the first 12 months, 68.1% of patients in the with hypoglycemia cohort discontinued basal insulin versus 53.9% in the without hypoglycemia cohort (p < .0001); more patients in the with hypoglycemia cohort had at least one hospitalization in the first year of follow-up (50.1% vs. 14.6%; p < .0001).

CONCLUSION

Patients with hypoglycemia soon after initiating basal insulin are at greater risk of discontinuation of their basal insulin therapy and hospitalization versus those who did not have hypoglycemic events within the first 6 months of basal insulin initiation. A limitation of this study is that it was a retrospective analysis of EMR data and the study may not be representative of all US patients with T2D on basal insulin and it cannot be assumed that every hypoglycemic event was recorded.
