Abstract
AIMS In type 2 diabetes control, self-management is an effective way to minimize the risk of developing complications and improve the quality of life. Self-determination theory (SDT) proposed a promising explanatory framework to predict self-regulated behavior which was particularly relevant for self-management. This study aimed to investigate whether SDT constructs can affect the self-management and controlling glycated hemoglobin A1c (HbA1c) levels in type 2 diabetic patients or not. METHODS This cross-sectional study was conducted from August to December 2022 at two diabetes clinics in Zahedan. The study included 300 patients with type 2 diabetes. Data collection was done using a researcher-administrated questionnaire that included demographic data, diabetes self-care activities, and self-determination constructs including autonomous support, autonomous motivation, and perceived competence. RESULTS The mean of the overall score of self-care activities was 34.62 ± 11.86 out of a maximum of 70. Patients in the fourth quarter (wealthiest) of the socioeconomic status had the highest mean self-care score (P = 0.003). There was a significant relationship between diet score with perceived competence (P = 0.009). Perceived competence (P<0.001) and controlled self-regulation (P<0.001) were the predictors of exercise score in diabetes patients. Independent self-regulation (P<0.001, r = 0.21) and overall self-regulation (P = 0.001, r = 0.19) were significantly related to blood-glucose testing score. There was a significant relationship between foot care score with perceived competence (P = 0.048, r = 0.11) and autonomous support (P = 0.013, r = 0.14). Multiple regression showed that exercise was the predictor of HbA1c (P = 0.014). CONCLUSION Exercise is crucial for achieving good individualized glycemic control and reducing the risk of diabetes complications. The findings provided valuable insights into the determinants of self-care activities in patients with type 2 diabetes and underscore the need for interventions that address socioeconomic disparities, enhance perceived competence, and provide autonomy support to improve diabetes self-care.

Diabetes Care 2020; 43:1557-1592. [PMID: 33534729 DOI: 10.2337/dci20-0017] [Citation(s) in RCA: 84] [Impact Index Per Article: 21.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 04/03/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To synthesize updated evidence on the cost-effectiveness (CE) of interventions to manage diabetes, its complications, and comorbidities. RESEARCH DESIGN AND METHODS We conducted a systematic literature review of studies from high-income countries evaluating the CE of diabetes management interventions recommended by the American Diabetes Association (ADA) and published in English between June 2008 and July 2017. We also incorporated studies from a previous CE review from the period 1985-2008. We classified the interventions based on their strength of evidence (strong, supportive, or uncertain) and levels of CE: cost-saving (more health benefit at a lower cost), very cost-effective (≤$25,000 per life year gained [LYG] or quality-adjusted life year [QALY]), cost-effective ($25,001-$50,000 per LYG or QALY), marginally cost-effective ($50,001-$100,000 per LYG or QALY), or not cost-effective (>$100,000 per LYG or QALY). Costs were measured in 2017 U.S. dollars. RESULTS Seventy-three new studies met our inclusion criteria. These were combined with 49 studies from the previous review to yield 122 studies over the period 1985-2017. A large majority of the ADA-recommended interventions remain cost-effective. Specifically, we found strong evidence that the following ADA-recommended interventions are cost-saving or very cost-effective: In the cost-saving category are 1) ACE inhibitor (ACEI)/angiotensin receptor blocker (ARB) therapy for intensive hypertension management compared with standard hypertension management, 2) ACEI/ARB therapy to prevent chronic kidney disease and/or end-stage renal disease in people with albuminuria compared with no ACEI/ARB therapy, 3) comprehensive foot care and patient education to prevent and treat foot ulcers among those at moderate/high risk of developing foot ulcers, 4) telemedicine for diabetic retinopathy screening compared with office screening, and 5) bariatric surgery compared with no surgery for individuals with type 2 diabetes (T2D) and obesity (BMI ≥30 kg/m2). In the very cost-effective category are 1) intensive glycemic management (targeting A1C <7%) compared with conventional glycemic management (targeting an A1C level of 8-10%) for individuals with newly diagnosed T2D, 2) multicomponent interventions (involving behavior change/education and pharmacological therapy targeting hyperglycemia, hypertension, dyslipidemia, microalbuminuria, nephropathy/retinopathy, secondary prevention of cardiovascular disease with aspirin) compared with usual care, 3) statin therapy compared with no statin therapy for individuals with T2D and history of cardiovascular disease, 4) diabetes self-management education and support compared with usual care, 5) T2D screening every 3 years starting at age 45 years compared with no screening, 6) integrated, patient-centered care compared with usual care, 7) smoking cessation compared with no smoking cessation, 8) daily aspirin use as primary prevention for cardiovascular complications compared with usual care, 9) self-monitoring of blood glucose three times per day compared with once per day among those using insulin, 10) intensive glycemic management compared with conventional insulin therapy for T2D among adults aged ≥50 years, and 11) collaborative care for depression compared with usual care. CONCLUSIONS Complementing professional treatment recommendations, our systematic review provides an updated understanding of the potential value of interventions to manage diabetes and its complications and can assist clinicians and payers in prioritizing interventions and health care resources.

Abstract
Aims: The costs associated with insulin therapy and diabetes-related complications represent a significant and growing economic burden for healthcare systems. The aim of this study was to evaluate the cost-effectiveness of switching to insulin degludec (degludec) vs continuing previous basal insulin, in Italian patients with type 1 (T1D) or type 2 (T2D) diabetes, using a long-term economic model.Materials and methods: Data were retrieved from a real-world population of patients from clinical practice in Italy. Clinical parameters included in the base-case model were change from baseline in HbA1c, rates of hypoglycemia, and basal and bolus insulin dose, at 6 months following switch to degludec. Costs of treatments were taken from official Italian pharmaceutical list prices and costs of hypoglycemia were based on the literature. The data were used to populate a long-term (lifetime) IQVIA CORE Diabetes Model to evaluate the incremental cost-effectiveness ratio (ICER) - cost per quality-adjusted life-year (QALY). The robustness of these results was tested with extensive sensitivity analyses by varying the time horizons and abolishing each of the treatment differences and previous basal insulins.Results: The total incremental cost for degludec vs previous basal insulin was €-6,310 and €-2,682 for patients with T1D and T2D, respectively; the switch to degludec resulted in a QALY gain of 0.781 and 0.628. The long-term ICER for degludec vs continuing the previous basal insulin regimen showed that degludec was dominant for both T1D and T2D, meaning that patient health was improved in terms of QALYs with lower healthcare costs. Sensitivity analyses showed that degludec remained dominant in most scenarios including after elimination of any benefit in non-severe hypoglycemia and insulin dose, in both T1D and T2D.Conclusions: Under routine care, switching to degludec is dominant, compared with continuing previous basal insulin, in Italian patients with T1D or T2D.

The Economic Burden of Insulin-Related Hypoglycemia in Adults with Diabetes: An Analysis from the Perspective of the Italian Healthcare System. Diabetes Ther 2018; 9:1037-1047. [PMID: 29600505 PMCID: PMC5984921 DOI: 10.1007/s13300-018-0418-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2018] [Indexed: 11/25/2022] Open
Abstract
INTRODUCTION The aim of this analysis was to estimate the cost of insulin-related hypoglycemia in adult patients with diabetes in Italy using the Local Impact of Hypoglycemia Tool (LIHT), and to explore the effect of different hypoglycemia rates on budget impact. METHODS Direct costs and healthcare resource utilization were estimated for severe and non-severe hypoglycemic episodes in Italy and applied to the population of adults with type 1 diabetes (T1DM) and type 2 diabetes (T2DM) and their corresponding hypoglycemia episode rates (0.49 severe and 53.3 non-severe episodes per year for T1DM, and 0.09 severe and 9.3 non-severe episodes per year for T2DM). Uncertainty around model inputs was explored through sensitivity and scenario analyses. RESULTS The direct cost of insulin-related hypoglycemia in Italy is estimated at €144.7 million per year, with €65 million attributable to severe episodes and €79.6 million due to non-severe episodes. The total cost of hypoglycemia is approximately 1.7-fold higher for T2DM (€91.7 million) than for T1DM (€53 million). The cost of a hypoglycemic episode ranges from €4.59 for a non-severe event where additional self-monitoring of blood glucose (SMBG) testing is the only cost incurred, to €5790.59 for a severe event that also requires an ambulance, A&E, hospitalization, and a visit to a diabetes specialist. A reduction in hypoglycemia event rates could result in substantial cost savings; for example, a 20% reduction in severe and non-severe hypoglycemia rates could result in a saving of €47,769 per general population of 100,000 people. CONCLUSIONS The LIHT highlights the substantial economic burden of insulin-related hypoglycemia in Italy, particularly with regards to non-severe hypoglycemia, an aspect of hypoglycemia that is often overlooked. This analysis may aid healthcare decision-making by allowing the costs of insulin therapies or diabetes self-management programs to be balanced with the savings provided by reductions in hypoglycemia.

Abstract
AIMS Self-monitoring of blood glucose is important for diabetes management in insulin-treated patients, but its effectiveness in patients treated with oral glucose lowering drugs only is not fully supported by current evidence. This paper aims to characterise the prescription patterns of blood glucose test strips (BGTS) in Portugal and estimate the potential cost-savings from the rational use of BGTS. METHODS A retrospective analysis of the Portuguese database of electronic medical prescriptions to assess the patterns of BGTS prescription. The database was searched for prescription, from 01 January 2016 to 31 December 2016, of insulin and other antidiabetics, as well as the associated prescriptions of BGTS. RESULTS 894,637 patients were prescribed antidiabetic medicines during 2016, 82.7% of which were prescribed oral glucose lowering drugs only. BGTS were prescribed to 456,179 patients, being more frequently prescribed in insulin-treated patients. Still, 42.8% of patients treated with oral glucose lowering drugs only were also prescribed BGTS, with large proportion of those being prescribed antidiabetic drugs with lower risk of causing hypoglycaemia and, even so, >200 BGTS/year. Several scenarios for a more rational use of BGTS were estimated to result in cost-savings of up to €9.5 million per year. CONCLUSIONS BGTS were prescribed to more than a third of patients treated with oral glucose lowering drugs only, despite accumulating evidence of their limited effectiveness in this population, resulting in substantial economic burden to the healthcare system. Given the estimated potential cost-savings, rational use of BGTS should be encouraged in Portugal.

Abstract
BACKGROUND There are an increasing number of studies using simulation models to conduct cost-effectiveness analyses for type 2 diabetes mellitus. OBJECTIVE To evaluate the relationship between improvements in glycosylated haemoglobin (HbA1c) and simulated health outcomes in type 2 diabetes cost-effectiveness studies. METHODS A systematic review was conducted on MEDLINE and EMBASE to collect cost-effectiveness studies using type 2 diabetes simulation models that reported modelled health outcomes of blood glucose-related interventions in terms of quality-adjusted life-years (QALYs) or life expectancy (LE). The data extracted included information used to characterise the study cohort, the intervention's treatment effects on risk factors and model outcomes. Linear regressions were used to test the relationship between the difference in HbA1c (∆HbA1c) and incremental QALYs (∆QALYs) or LE (∆LE) of intervention and control groups. The ratio between the ∆QALYs and ∆LE was calculated and a scatterplot between the ratio and ∆HbA1c was used to explore the relationship between these two. RESULTS Seventy-six studies were included in this research, contributing to 124 pair of comparators. The pooled regressions indicated that the marginal effect of a 1% HbA1c decrease in intervention resulted in an increase in life-time QALYs and LE of 0.371 (95% confidence interval 0.286-0.456) and 0.642 (95% CI 0.494-0.790), respectively. No evidence of heterogeneity between models was found. An inverse exponential relationship was found and fitted between the ratio (∆QALY/∆LE) and ∆HbA1c. CONCLUSION There is a consistent relationship between ∆HbA1c and ∆QALYs or ∆LE in cost-effectiveness analyses using type 2 diabetes simulation models. This relationship can be used as a diagnostic tool for decision makers.

Abstract
AIMS To compare the effects of structured and routine testing regimens used in self-monitoring of blood glucose (SMBG) on glycemic control and diabetes self-management in insulin-naïve type 2 diabetes patients. METHODS Sixty-two outpatients with insulin-naïve type 2 diabetes were randomly allocated into two less-frequent SMBG usage groups: a structured testing group (STG) and a routine testing group (RTG). Subjects in STG measured 7-points on SMBG for 3 consecutive days once every two months without daily testing; subjects in RTG measured SMBG 3 times each week before breakfast on Monday and Friday and before dinner on Wednesday. The primary endpoint was HbA1c reduction. The secondary endpoints were change in body weight, blood pressure, treatment change, and self-management performance change. RESULTS HbA1c levels were significantly decreased by 0.32% (3.50mmol/mol) in STG, partly because physicians changed medications more actively. In contrast, body weight and systolic/diastolic blood pressure were significantly reduced by 0.94kg and 6.8/4.7mmHg, respectively, in RTG, possibly related to the increased diet and exercise score in RTG. CONCLUSIONS Structured testing without daily testing is beneficial for glycemic control; routine testing 3 times a week is more helpful for daily self-management. In low SMBG frequency usage, these two regimens can be utilized according to individual diabetic conditions.

Abstract
Drawing on Self-Determination Theory, this study explored the motivational profiles toward Physical Activity (PA) among adults with type 2 diabetes and the relationships between motivational profile, perceived competence and PA. Participants were 350 men and women (Mean age 62.77 years) who were interviewed on their motivations toward PA, perceived level of competence to practice, and PA practice. Cluster analyses reveal the existence of three distinct profiles: "High Combined" (ie, high scores on motivations ranging from intrinsic to external regulation, moderate level on amotivation), "Self-Determined" (ie, high scores on intrinsic, integrated, and identified regulations; low scores on other regulations), and "Moderate" (ie, moderate scores on all regulations). Participants with "High Combined" and "Self-Determined" profiles reported higher perceived competence and longer leisure-time PA practice in comparison to those with a "Moderate" profile. This study highlights the necessity of adopting a person-centered approach to better understand motivation toward PA among type 2 diabetics.

Abstract
BACKGROUND This analysis models the cost-effectiveness of real-time continuous glucose monitoring (RT-CGM) using evidence from a randomized controlled trial (RCT) that demonstrated RT-CGM reduced A1C, for up to 9 months after using the technology, among patients with type 2 diabetes not on prandial insulin. RT-CGM was offered short-term and intermittently as a self-care tool to inform patients' behavior. METHOD The analyses projected lifetime clinical and economic outcomes for RT-CGM versus self-monitoring of blood glucose by fingerstick only. The base-case analysis was consistent with the RCT (RT-CGM for 2 weeks on/1 week off over 3 months). A scenario analysis simulated outcomes of an RT-CGM "refresher" after the active intervention of the RCT. Analyses used the IMS CORE Diabetes Model and were conducted from a US third-party payer perspective, including direct costs obtained from published sources and inflated to 2011 US dollars. Costs and health outcomes were discounted at 3% per annum. RESULTS Life expectancy (LE) and quality-adjusted life expectancy (QALE) from RT-CGM were 0.10 and 0.07, with a cost of $653/patient over a lifetime. Incremental LE and QALE from a "refresher" were 0.14 and 0.10, with a cost of $1312/patient over a lifetime, and incremental cost-effectiveness ratios were $9319 and $13 030 per LY and QALY gained. CONCLUSIONS RT-CGM, as a self-care tool, is a cost-effective disease management option in the US for people with type 2 diabetes not on prandial insulin. Repeated use of RT-CGM may result in additional cost-effectiveness.

Abstract
INTRODUCTION Diabetes mellitus is a chronic degenerative disease associated with a high risk of chronic complications and comorbidities. However, very few data are available on the associated cost. The objective of this study is to identify the available information on the epidemiology of the disease and estimate the average annual cost incurred by the National Health Service and Society for the Treatment of Diabetes in Italy. METHODS A probabilistic prevalence cost of illness model was developed to calculate an aggregate measure of the economic burden associated with the disease, in terms of direct medical costs (drugs, hospitalizations, monitoring and adverse events) and indirect costs (absenteeism and early retirement). A systematic review of the literature was conducted to determine both the epidemiological and economic data. Furthermore, a one-way and probabilistic sensitivity analysis with 5,000 Monte Carlo simulations was performed to test the robustness of the results and define a 95% CI. RESULTS The model estimated a prevalence of 2.6 million patients under drug therapies in Italy. The total economic burden of diabetic patients in Italy amounted to €20.3 billion/year (95% CI €18.61 to €22.29 billion), 54% of which are associated with indirect costs (95% CI €10.10 to €11.62 billion) and 46% with direct costs only (95% CI €8.11 to €11.06 billion). CONCLUSIONS This is the first study conducted in Italy aimed at estimating the direct and indirect cost of diabetes with a probabilistic prevalence approach. As might be expected, the lack of information means that the real burden of diabetes is partly underestimated, especially with regard to indirect costs. However, this is a useful approach for policy makers to understand the economic implications of diabetes treatment in Italy.

Abstract
This document represents the official position of the American Association of Clinical Endocrinologists and American College of Endocrinology. Where there were no randomized controlled trials or specific U.S. FDA labeling for issues in clinical practice, the participating clinical experts utilized their judgment and experience. Every effort was made to achieve consensus among the committee members. Position statements are meant to provide guidance, but they are not to be considered prescriptive for any individual patient and cannot replace the judgment of a clinician.

Abstract
Self-monitoring of blood glucose (SMBG) is universally considered to be an integral part of type 1 diabetes management and crucial for optimizing the safety and efficacy of complex insulin regimens. This extends to type 2 diabetes patients on intensive insulin therapy, and there is also a growing body of evidence suggesting that structured SMBG is beneficial for all type 2 diabetes patients, regardless of therapy. However, access to SMBG can be limited in many countries in Central and Eastern Europe. A consensus group of diabetes experts from 10 countries in this region (with overlapping historical, political, and social environments)--Bulgaria, Croatia, Czech Republic, Hungary, Poland, Romania, Serbia, Slovakia, Slovenia, and Ukraine--was formed to discuss the role of SMBG across the spectrum of patients with diabetes. The group considered SMBG to be an essential tool that should be accessible to all patients with diabetes, including those with non-insulin-treated type 2 diabetes. The current article summarizes the evidence put forward by the consensus group and provides their recommendations for the appropriate use of SMBG as part of individualized patient management. The ultimate goal of these evidence-based recommendations is to help patients and providers in Central and Eastern Europe to make optimal use of SMBG in order to maximize the efficacy and safety of glucose-lowering therapies, to prevent complications, and to empower the patient to play a more active role in the management of their diabetes.

Abstract
OBJECTIVE Realise a review of studies of economic evaluation about the ambulatory monitoring of capillary glucose (AMGC) in diabetic type II persons. METHODOLOGY A review of the literature was conducted, in MedLine, various websites, referenced paper and provided by expert's persons. RESULTS Five studies concluded that the AMGC was a cost-effective strategic, of this papers use Kaiser Permanente data base, its make that these studies could be considered a solely one study. The rest of the papers did not find difference in the AMGC use. CONCLUSIONS The use of AMGC has an uncertainty efficiency. More studies are needed.

Abstract
BACKGROUND Self-monitoring of blood glucose (SMBG) is a proven tool to improve glycemic control, even if it might increase direct costs for diabetes management. In Italy, the purchase, prescription rules and responsibilities, and distribution of testing strips per type of patient are managed differently in each of the 20 Italian regions. The Italian scientific societies for diabetes (Società Italiana Diabetologia [SID] and Associazione Medici Diabetologi [AMD]) have issued validated guidelines for SMBG, but not all regions apply them. We investigated whether following SID-AMD guidelines would help decreasing SMBG and diabetes healthcare costs in Italy. MATERIALS AND METHODS We compared the regions applying and not applying SMBG guidelines for the mean number of testing strips used, number of hospitalizations (with the principal diagnosis of diabetes, excluding diabetes complications), and duration of hospitalization, as indirect measures of SMBG cost. RESULTS Regions applying the guidelines recorded higher SMBG testing strip utilization than regions not applying guidelines, but they recorded fewer hospitalizations for diabetes (36.2 ± 11.3 vs. 79.9 ± 27.8 hospitalizations per 100,000 inhabitants, P<0.002) and fewer days in the hospital (363 ± 106 vs. 685 ± 194 days of hospitalization for diabetes per 100,000 inhabitants, P<0.002). CONCLUSIONS Our data suggest that application of guidelines for SMBG prescription and a strict cooperation between health providers and regional health economic deciders were associated with greater utilization of SMBG testing strips. They were also associated with significantly reduced number of hospitalizations and reduced overall duration of hospitalization for patients with diabetes, potentially saving healthcare costs.

Abstract
Diabetes mellitus has a major impact on costs for healthcare and society. The estimation for 2010 is that investment in diabetes will reach 11.6% of public healthcare expenses worldwide. The expected rise in the prevalence of diabetes over the coming decades may create problems for the sustainability of healthcare systems, such as those in Spain. The rise in direct costs is the main issue in diabetes, especially the treatment of acute and chronic complications that often need hospital care. Severe hypoglycemia (SH) is the most frequent acute complication. In Spain, the incidence of SH is estimated at two episodes per patient per year for Type 1 diabetes and one to two episodes for advanced Type 2 diabetes requiring insulin treatment. Although results vary, Spanish national data provide an estimated cost of approximately €3500 per SH episode. It also has a major influence on indirect costs, mainly related to reduced productivity, absenteeism and occasionally early retirement, and affects direct health, such as quality of life. As a result of SH, patients acquire a fear of new hypoglycemic episodes, which makes them modify their behavior and habits and, in the long term, has the potential to negatively impact metabolic control. Educational programs for healthcare professionals and patients with diabetes, increased involvement of patients in the management of their illness and regular self-measurement of blood glucose are all strategies aimed at minimizing the social and economic effects of severe hypoglycemia.
