Abstract
OBJECTIVE The objective of this review was to examine the role of adverse drug events (ADEs) caused by pharmacological interventions in cost-effectiveness models for diabetes mellitus, diabetic retinopathy, and diabetic macular edema. INTRODUCTION Guidelines for economic evaluation recognize the importance of including ADEs in the analysis, but in practice, consideration of ADEs in cost-effectiveness models seem to be vague. Inadequate inclusion of these harmful outcomes affects the reliability of the results, and the information provided by economic evaluation could be misleading. Reviewing whether and how ADEs are incorporated in cost-effectiveness models is necessary to understand the current practices of economic evaluation. INCLUSION CRITERIA Studies included were published between 2011-2022 in English, representing cost-effectiveness analyses using modeling framework for pharmacological interventions in the treatment of diabetes mellitus, diabetic retinopathy, or diabetic macular edema. Other types of analyses and other types of conditions were excluded. METHODS The databases searched included MEDLINE (PubMed), CINAHL (EBSCOhost), Scopus, Web of Science Core Collection, and NHS Economic Evaluation Database. Gray literature was searched via the National Institute for Health and Care Excellence, European Network for Health Technology Assessment, the National Institute for Health and Care Research, and the International Network of Agencies for Health Technology Assessment. The search was conducted on January 1, 2023. Titles and abstracts were screened for inclusion by 2 independent reviewers. Full-text review was conducted by 3 independent reviewers. A data extraction form was used to extract and analyze the data. Results were presented in tabular format with a narrative summary, and discussed in the context of existing literature and guidelines. RESULTS A total of 242 reports were extracted and analyzed in this scoping review. For the included analyses, type 2 diabetes was the most common disease (86%) followed by type 1 diabetes (10%), diabetic macular edema (9%), and diabetic retinopathy (0.4%). The majority of the included analyses used a health care payer perspective (88%) and had a time horizon of 30 years or more (75%). The most common model type was a simulation model (57%), followed by a Markov simulation model (18%). Of the included cost-effectiveness analyses, 26% included ADEs in the modeling, and 13% of the analyses excluded them. Most of the analyses (61%) partly considered ADEs; that is, only 1 or 2 ADEs were included. No difference in overall inclusion of ADEs between the different conditions existed, but the models for diabetic retinopathy and diabetic macular edema more often omitted the ADE-related impact on quality of life compared with the models for diabetes mellitus. Most analyses included ADEs in the models as probabilities (55%) or as a submodel (40%), and the most common source for ADE incidences were clinical trials (65%). CONCLUSIONS The inclusion of ADEs in cost-effectiveness models is suboptimal. The ADE-related costs were better captured than the ADE-related impact on quality of life, which was most pronounced in the models for diabetic retinopathy and diabetic macular edema. Future research should investigate the potential impact of ADEs on the results, and identify the criteria and policies for practical inclusion of ADEs in economic evaluation.

Abstract
Purpose The higher costs of insulin analogs including short-acting insulin aspart (IAsp) and long-acting insulin glargine (IGla) have restricted their widespread uptake despite having improved pharmacokinetic and pharmacodynamic properties and patient convenience. This study aims to evaluate the cost-effectiveness of IAsp versus Regular Insulin (RI) and IGla versus NPH Insulin in type 1 and 2 diabetes from the perspective of the Iranian healthcare system. Methods Clinical data including HbA1c levels, hypoglycemia, weight gain, and health-related quality of life were derived from the included systematic review and meta-analysis studies. Different methods of pharmacoeconomic evaluation were used for an annual time horizon. Utility decrements for diabetes-related complications were extracted from the literature. Direct medical costs were calculated in 2022 prices. A one-way sensitivity analysis was also performed. Results In type 1 diabetes, IAsp was associated with more costs and effects in terms of reducing HbA1c compared with RI. An incremental cost of $83 was estimated to obtain an additional 1% reduction in HbA1c per patient per year. Similarly, an incremental cost of $16 was estimated for IGla compared with NPH. In type 2 diabetes, IAsp and RI were associated with equal efficacy and safety. For IGla versus NPH, the incremental cost-effectiveness ratio was calculated at $1975 per quality-adjusted life-year. The robustness of the result was confirmed through sensitivity analysis. Conclusion Insulin analogs, IAsp and IGla, are cost-effective for type 1 diabetes versus human insulins, RI and NPH. For type 2 diabetes, IAsp is not cost-effective when compared with RI. For IGla versus NPH, however, the incremental cost-effectiveness ratio seems to be within the accepted thresholds.

Abstract
CONTEXT Hypoglycemia in people with diabetes is common, especially in those taking medications such as insulin and sulfonylureas (SU) that place them at higher risk. Hypoglycemia is associated with distress in those with diabetes and their families, medication nonadherence, and disruption of life and work, and it leads to costly emergency department visits and hospitalizations, morbidity, and mortality. OBJECTIVE To review and update the diabetes-specific parts of the 2009 Evaluation and Management of Adult Hypoglycemic Disorders: Endocrine Society Clinical Practice Guideline and to address developing issues surrounding hypoglycemia in both adults and children living with diabetes. The overriding objectives are to reduce and prevent hypoglycemia. METHODS A multidisciplinary panel of clinician experts, together with a patient representative, and methodologists with expertise in evidence synthesis and guideline development, identified and prioritized 10 clinical questions related to hypoglycemia in people living with diabetes. Systematic reviews were conducted to address all the questions. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was used to assess the certainty of evidence and make recommendations. RESULTS The panel agreed on 10 questions specific to hypoglycemia risk and prevention in people with diabetes for which 10 recommendations were made. The guideline includes conditional recommendations for use of real-time continuous glucose monitoring (CGM) and algorithm-driven insulin pumps in people with type 1 diabetes (T1D), use of CGM for outpatients with type 2 diabetes at high risk for hypoglycemia, use of long-acting and rapid-acting insulin analogs, and initiation of and continuation of CGM for select inpatient populations at high risk for hypoglycemia. Strong recommendations were made for structured diabetes education programs for those at high risk for hypoglycemia, use of glucagon preparations that do not require reconstitution vs those that do for managing severe outpatient hypoglycemia for adults and children, use of real-time CGM for individuals with T1D receiving multiple daily injections, and the use of inpatient glycemic management programs leveraging electronic health record data to reduce the risk of hypoglycemia. CONCLUSION The recommendations are based on the consideration of critical outcomes as well as implementation factors such as feasibility and values and preferences of people with diabetes. These recommendations can be used to inform clinical practice and health care system improvement for this important complication for people living with diabetes.

Abstract
<b><i>Background:</i></b> Progression of type 2 diabetes will necessitate the use of injectable therapies in a significant number of people. Co-formulations of degludec with liraglutide (IDegLira) and glargine with lixisenatide (IGlarLixi) are currently recommended for intensification in people with type 2 diabetes on basal insulin or glucagon-like peptide receptor agonist (GLP-1RA) alone or in people with type 2 diabetes who are naïve to insulin with very high glycated haemoglobin. Co-formulation of aspart with degludec (IDegAsp) is recommended as a substitute for premixed insulin. The aim of this article is to review the evidence in the use of co-formulations as the first injectable in type 2 diabetes and its clinical implications. <b><i>Summary:</i></b> In people with type 2 diabetes who are naïve to insulin or GLP-1RA, IDegLira and IGlarLixi achieved stable and durable glycaemic control over a wide range of baseline glycated haemoglobin (HbA1c) levels. People on IDegLira and IGlarLixi had lesser risk of hypoglycaemia and weight gain in studies compared to basal insulin and lesser gastrointestinal adverse effects in comparison to GLP-1RA. IDegAsp achieved similar glycaemic control to basal and premixed insulin with lesser risk of nocturnal hypoglycaemia. <b><i>Key Messages:</i></b> IDegLira, IGlarLixi, and IDegAsp can be used as the first injectable in people with type 2 diabetes with very high glycated haemoglobin on oral antidiabetic drugs. These co-formulations combine efficacy and durability with lesser injection burden. The components of these agents have proven cardiovascular and renal safety. Their limitations in flexibility of dosing, renal and cardiovascular considerations, and adverse effects are discussed.

Abstract
BACKGROUND Insulin analogues have a pharmacokinetic advantage over human insulin and are increasingly used to treat diabetes mellitus. A summary of their cost effectiveness versus other available treatments was required. OBJECTIVE Our objective was to systematically review the published cost-effectiveness studies of insulin analogues for the treatment of patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). METHODS We searched major databases and health technology assessment agency reports for economic evaluation studies published up until 30 September 2015. Two reviewers performed data extraction and assessed the quality of the data using the CHEERS (Consolidated Health Economic Evaluation Reporting Standards) guidelines. RESULTS Seven of the included studies assessed short-acting insulin analogues, 12 assessed biphasic insulin analogues, 30 assessed long-acting insulin analogues and one assessed a combination of short- and long-acting insulin analogues. Only 17 studies involved patients with T1DM, all were modelling studies and 12 were conducted in Canada. The incremental cost-effectiveness ratios (ICERs) for short-acting insulin analogues ranged from dominant to $US435,913 per quality-adjusted life-year (QALY) gained, the ICERs for biphasic insulin analogues ranged from dominant to $US57,636 per QALY gained and the ICERs for long-acting insulin analogues ranged from dominant to $US599,863 per QALY gained. A total of 15 studies met all the CHEERS guidelines reporting quality criteria. Only 26 % of the studies assessed heterogeneity in their analyses. CONCLUSION Current evidence indicates that insulin analogues are cost effective for T1DM; however, evidence for their use in T2DM is not convincing. Additional evidence regarding compliance and efficacy is required to support the broader use of long-acting and biphasic insulin analogues in T2DM. The value of insulin analogues depends strongly on reductions in hypoglycaemia event rates and its efficacy in lowering glycated haemoglobin (HbA1c).

Effects of analogue insulin in multiple daily injection therapy of type 2 diabetes on postprandial glucose control and cardiac function compared to human insulin: a randomized controlled long-term study. Cardiovasc Diabetol 2016; 15:7.

Abstract
Background The prevention of cardiovascular disease, including diastolic cardiac dysfunction with its high prevalence and ominous prognosis, is a therapeutic challenge for patients with type 2 diabetes. Both short and long-acting insulin analogues (AI) have been shown to reduce glucose variability and provide potential benefit for cardiovascular disease although the effects on cardiac function have not yet been evaluated. This long-term, prospective, randomized controlled trial in patients with type 2 diabetes (T2D) tested the hypothesis that a multiple daily injection regimen (MDI) with AI improves postmeal glucose excursions in comparison to human insulin (HI) and that the effects of AI improve diastolic cardiac function. Methods For 36 months, MDI treatment in 109 T2D patients was adapted every 3 months (targets: fasting glucose ≤ 110 mg/dl, postmeal glucose ≤ 150 mg/dl) in both groups: AI (insulin detemir and insulin aspart, n = 61) and HI (NPH-insulin and regular HI, n = 48). Diastolic cardiac function (myocardial velocity E’ using tissue Doppler imaging and the mitral inflow ratio E/A) and vascular function were assessed before and 2 h after a standardized breakfast (48 g carbohydrates). At baseline, both groups were comparable with regards to demographic, cardiac and metabolic data. Analysis of data included traditional statistics as well as the use of a multiple imputation technique shown in brackets [ ]. Results At 36 months, the primary endpoint, postmeal glucose, decreased by 20 ± 62 mg/dl, p = 0.038 [p = 0.021] with AI and increased insignificantly with HI (inter-group p = 0.032 [p = 0.047]) to postmeal glucose levels of 161 ± 39 with AI vs. 195 ± 54 mg/dl with HI (inter-group p = 0.002 [p = 0.010]) whereas the levels of fasting glucose and HbA1c were comparable. With AI, postmeal E’ improved by 0.6 ± 1.4 cm/s, p = 0.009 [p = 0.002] and fasting E’ by 0.4 ± 1.4 cm/s, p = 0.069 [p = 0.013], however, E’ remained unchanged with HI. These changes were consistent with those of the traditional parameter E/A. Conclusions MDI with AI results in better postmeal glucose control compared to HI. The treatment with AI is associated with improved diastolic cardiac function. ClinicalTrials.gov (NTC00747409)

Abstract
A systematic review identified studies eliciting utility decrements from myocardial infarction (MI) and stroke in patients with Type 2 diabetes mellitus (T2DM) and examined their use in economic models of new diabetes treatments. In 16 utility studies in patients with T2DM, utility decrements in the first year ranged from 0.017 to 0.226 for MI and from 0.034 to 0.590 for stroke. Sixteen of 19 economic evaluations of new treatments for T2DM included utility decrements for an MI and/or stroke from one of the 16 utility studies. Decrements for MI ranged from 0.012 to 0.180 in the first year. Decrements for stroke ranged from 0.044 to 0.690 in the first year. Utility studies in patients with T2DM provide little information about changes in utility decrements by time since the event and by disease severity. Cost-effectiveness studies do not always indicate how these values were used in the analysis.

Abstract
INTRODUCTION Cardiovascular disease (CVD) is a common and serious complication of type 2 diabetes mellitus (T2DM) often linked to the increased morbidity and mortality associated with T2DM. Monitoring and treating risk factors for CVD are important elements of diabetes management. This review aims to examine CV risk in people with relatively early and mild diabetes who are at substantial risk of CVD; it considers the impact of insulin therapy on this risk by focusing on key studies in patients with diabetes. METHODS A literature search was carried out using PubMed to identify key publications, between 2008 and 2013, related to insulin and its possible effect on CVD. This review examines CV risk in diabetes and the impact of insulin therapy on this risk. RESULTS Studies have shown that treatment with insulin glargine is associated with marked improvement in the lipid profile of people with T2DM. Intensive insulin therapy has been shown to lower mortality rates in people with diabetes following acute myocardial infarction after 1 year. Retrospective data also indicate that insulin reduces the risk of CVD events, regardless of whether people had comorbidities known to increase CV risk. The prospective ORIGIN (Outcome Reduction with Initial Glargine Intervention) trial found that treatment with insulin glargine had a neutral effect with regard to CV outcomes in people with prediabetes or early diabetes, compared with standard care. CONCLUSIONS Other ongoing, large-scale studies of insulin therapy should provide further insights into whether or not insulin therapy can influence long-term CV outcomes.

Abstract
PURPOSE To simulate national estimates of prepregnancy and gestational diabetes mellitus (GDM) in non-Hispanic white (NHW) and non-Hispanic black (NHB) women. METHODS Prepregnancy diabetes and GDM were estimated as a function of age, race/ethnicity, and body mass index (BMI) using South Carolina live singleton births from 2004-2008. Diabetes risk was applied to a simulated population. Age, natality and BMI were assigned to women according to race- and age-specific US Census, Natality and National Health and Nutrition Examination Surveys (NHANES) data, respectively. RESULTS From 1980-2008, estimated GDM prevalence increased from 4.11% to 6.80% [2.68% (95% CI 2.58%-2.78%)] and from 3.96% to 6.43% [2.47% (95% CI 2.39%-2.55%)] in NHW and NHB women, respectively. In NHW women prepregnancy diabetes prevalence increased 0.90% (95% CI 0.85%-0.95%) from 0.95% in 1980 to 1.85% in 2008. In NHB women from 1980 through 2008 estimated prepregnancy diabetes prevalence increased 1.51% (95% CI 1.44%-1.57%), from 1.66% to 3.16%. CONCLUSIONS Racial disparities in diabetes prevalence during pregnancy appear to stem from a higher prevalence of prepregnancy diabetes, but not GDM, in NHB than NHW.

Abstract
AIMS Insulin aspart has a higher ability to treat postprandial glucose than regular human insulin, which may have favourable cardiovascular effects. The aim was to collect and compare the incidence of recorded macro- and microvascular events in patients with type 2 diabetes with insulin aspart or regular human insulin in general practices. METHODS Computerized data from 3154 aspart and 3154 regular insulin users throughout Germany (Disease Analyzer, January 2000 to July 2011) were analysed after matching for age (60 ± 10 years), sex (men: 57%), health insurance (private: 5.8%) and diabetes treatment period in practice (2.2 ± 2.5 years). Hazard ratios (HR; Cox regression) for macro- or microvascular outcomes (follow-up: 3.5 years) were further adjusted for diabetologist care, practice region, hypertension, hyperlipidaemia, co-medication (basal insulin, oral antidiabetics, antihypertensives, lipid-lowering agents and antithrombotic drugs), previous treatment with rapid-acting insulins, hypoglycaemia and the Charlson co-morbidity score. Furthermore, adjustment was carried out for baseline microvascular complications when analysing macrovascular outcomes and vice versa. RESULTS Overall, the risk of combined macrovascular outcomes was 15% lower for insulin aspart users (p = 0.01). For insulin aspart there was also a decreased risk incident stroke [HR: 0.58; 95% confidence interval (CI): 0.45-0.74], myocardial infarction (HR: 0.69; 95% CI: 0.54-0.88) and peripheral vascular disease (HR: 0.80; 95% CI: 0.69-0.93). For microvascular complications (retinopathy, neuropathy and nephropathy), no significant differences were observed (HR: 0.96; 95% CI: 0.87-1.06). CONCLUSION Use of the rapid-acting insulin analogue aspart was associated with a reduced incidence of macrovascular outcomes in type 2 diabetes in general practices. It is important to confirm this finding in a randomized controlled trial.
