Abstract
This study examined the association between persistence to basal insulin and clinical and economic health outcomes. The question of whether a persistence measure for basal insulin could be leveraged in quality measurement was also explored. Using the IBM-Truven MarketScan Commercial and Medicare Supplemental Databases from 1 January 2011 to 31 December 2015, a total of 14,126 subjects were included in the analyses, wherein 9,898 (70.1%) were categorized as persistent with basal insulin therapy. Basal insulin persistence was associated with lower A1C, fewer hospitalizations and emergency department visits, and lower health care expenditures. Quality measures based on prescription drug claims for basal insulin are feasible and should be considered for guiding quality improvement efforts.

Abstract
BACKGROUND AND AIM One of the greatest barriers to the treatment of T2DM is nonadherence which particularly applies to insulin therapy. There is a need for a comprehensive overview of all factors associated with nonadherence to insulin therapy. The aim of this study was to identify factors associated with adherence or nonadherence to insulin therapy among adults with T2DM. METHODS A scoping review was conducted in accordance with the PRISMA 2020 statement. A systematic search was performed in PubMed, Cinahl, and Web of Science (January 2013 to March 2023). RESULTS A final sample of 48 studies was included in the scoping review. The synthesis revealed 30 factors associated with adherence or nonadherence. The factors were grouped into 6 themes: demographics, attitude and perceptions, management of diabetes, impact on daily living, disease and medication, and healthcare system. CONCLUSION The most prominent factors identified were age, cost of healthcare, personal beliefs towards insulin therapy, social stigma, patient education, complexity of diabetes treatment, impact of insulin therapy on daily life, and fear of side effects. The results indicate a need for further research to determine threshold values for the factors associated with adherence or nonadherence.

Treatment-Related Attributes of Diabetes Therapies and How People with Type 2 Diabetes Report Their Impact on Indicators of Medication-Taking Behaviors. Patient Prefer Adherence 2022; 16:1919-1939. [PMID: 35958887 PMCID: PMC9359496 DOI: 10.2147/ppa.s367046] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 07/08/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose Understanding the treatment-related attributes influencing medication-taking behaviors in people with type 2 diabetes (T2D) is important for delivery of patient-centered care. This review aimed to identify and summarize studies in which people with T2D (PwD) directly indicated the treatment-related attributes associated with medication-taking behaviors or intentions. Materials and Methods EMBASE and PubMed were searched for studies (Jan 2005-May 2021) reporting the link between PwD-expressed diabetes treatment-related attributes and the decision to initiate, adhere to, or discontinue a T2D medication. Eligible studies reported attributes associated with oral antidiabetes drugs or injectables (not insulin). Studies not explicitly exploring the link between attributes and indicators of behaviors (eg most discrete-choice experiments [DCE] and those interrogating electronic medical records or claims databases) were excluded, as were studies where the link between attribute and behavior came from anyone but the PwD. Results Of the 6464 studies identified, 16 were included. Studies were conducted across multiple countries; the USA was most represented (n = 8 studies). The impact of treatment attributes was described on indicators of initiation (n = 3), adherence (n = 12), and discontinuation (n = 4). Some studies evaluated multiple behaviors. PwD perspectives were solicited by structured questionnaires (n = 10), qualitative approaches (n = 4), or DCE explicitly exploring the link to medication-taking behaviors (n = 2). Closed- (n = 9) and open-ended questions (n = 7) were employed. Across studies, several factors including glycemic efficacy (n = 9), weight change (n = 9), dosing frequency (n = 9), hypoglycemia (n = 8), gastrointestinal adverse events (n = 8), regimen complexity (n = 6), route of administration (n = 3), and cardiovascular risk (n = 1) were reported as influencing behaviors, being motivators or barriers to initiation, adherence, or discontinuation. Conclusion Several attributes influence how PwD take their medications. Insights gained directly from PwD have the potential to assist stakeholders in making more informed, patient-centered, treatment decisions, thus choosing and managing medications that PwD are comfortable initiating and persisting with over the longer term.

Abstract
PURPOSE Type 2 diabetes (T2D) medication adherence is poor and is impacted by individual drug characteristics. Treatment-associated weight change can affect medication-taking behavior. This review aimed to explore weight change on T2D therapy and consider its impact on adherence and discontinuation. METHODS Searches were conducted in MEDLINE and EMBASE (2005 to September 2020), and among recent congress abstract books for studies providing data on medication adherence or discontinuation and weight change in people with T2D (PwD). RESULTS Nine studies meeting the inclusion criteria were identified from 9188 bibliographic records. All three studies exploring weight change and discontinuation reported weight loss to be associated with higher persistence. Seven studies of varying design explored weight change and adherence. Four reported absolute weight change (kg) and adherence: one pooled data from different diabetes medications and demonstrated that self-reported adherence was significantly associated with weight loss; however, three studies found that weight change in adherent PwD was in the direction of the known weight profile (loss/gain) of the evaluated drug. Categorical weight loss (≥3%) and adherence were reported in two studies: one reported that numerically more adherent versus non-adherent PwD lost ≥3% weight regardless of the drug's weight profile, the other showed that early weight loss with a glucagon-like peptide-1 agonist was significantly associated with better adherence. One study reported adherence by categorical weight change; as weight loss increased, adherence scores improved, regardless of drug type. CONCLUSION Findings suggest that discontinuation rates may be lower in PwD who lose as compared to those who gain weight on T2D treatment. The evidence base on adherence and weight change is more challenging to interpret due to the range of study designs. Given the importance of weight control in T2D, further research exploring the individual's treatment, weight journey, and behaviors over time should be undertaken.

Abstract
BACKGROUND Evidence suggests that insulin therapy of patients with type 2 diabetes mellitus (T2DM) is frequently discontinued. However, the reasons for discontinuing insulin and factors associated with insulin discontinuation in this patient population are not well understood. METHODS We conducted a retrospective cohort study of adults with T2DM prescribed insulin between 2010 and 2017 at Partners HealthCare. Reasons for discontinuing insulin and factors associated with insulin discontinuation were studied using electronic medical records (EMR) data. Natural language processing (NLP) was applied to identify reasons from unstructured clinical notes. Factors associated with insulin discontinuation were extracted from structured EMR data and evaluated using multivariable logistic regression. RESULTS Among 7009 study patients, 2957 (42.2%) discontinued insulin within 12 months after study entry. Most patients who discontinued insulin (2121 / 71.7%) had reasons for discontinuation documented. The most common reasons were improving blood glucose control (33.2%), achieved weight loss (18.5%) and initiation of non-insulin diabetes medications (16.7%). In multivariable analysis adjusted for demographics and comorbidities, patients were more likely to discontinue either basal or bolus insulin if they were on a basal-bolus regimen (OR 1.6, 95% CI 1.3 to 1.8; p < 0.001) or were being seen by an endocrinologist (OR 2.6; 95% CI 2.2 to 3.0; p < 0.001). CONCLUSIONS In this large real-world evidence study conducted in an area with a high penetration of health insurance, insulin discontinuation countenanced by healthcare providers was common. In most cases it was linked to achievement of glycemic control, achieved weight loss and initiation of other diabetes medications. Factors associated with and stated reasons for insulin discontinuation were different from those previously described for non-adherence to insulin therapy, identifying it as a distinct clinical phenomenon.

Abstract
AIM To report the effectiveness and safety of insulin glargine 300 U/mL (Gla-300) versus standard-of-care basal insulin analogues (SOC-BI) at 12 months in the ACHIEVE Control trial, which is a prospective pragmatic randomized real-life study in insulin-naïve adults with type 2 diabetes (T2D). METHODS A total of 3304 insulin-naïve adults with T2D and glycated haemoglobin (HbA1c) concentration of 64 to 97 mmol/mol (8.0% to 11.0%) after ≥1 year of treatment with two or more antihyperglycaemic agents were randomized to Gla-300 or SOC-BI. Key secondary endpoints included HbA1c target attainment without documented symptomatic (≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia at 12 months. RESULTS At 12 months, 26.1% (Gla-300) and 23.7% (SOC-BI) of adults achieved HbA1c targets without documented symptomatic (≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia (odds ratio [OR] 1.14, 95% confidence interval [CI] 0.97-1.35); 33.0% and 29.5%, respectively, achieved HbA1c targets without documented symptomatic (<3.0 mmol/L [<54 mg/dL]) or severe hypoglycaemia (OR 1.19, 95% CI 1.02-1.38). The OR for HbA1c target achievement was 1.15 (95% CI 0.99-1.34), and favoured Gla-300 versus SOC-BI for absence of documented symptomatic or severe hypoglycaemia at 12 months for both ≤3.9 mmol/L (≤70 mg/dL; OR 1.21, 95% CI 1.05-1.40) and < 3.0 mmol/L (<54 mg/dL; OR 1.26, 95% CI 1.07-1.48). CONCLUSION Gla-300 tended to be associated with lower hypoglycaemia risk than SOC-BI in real-world clinical practice during the 12-month follow-up.

Abstract
Background Adherence to type 2 diabetes management is defined as the extent to which the behaviour of a person matches the one recommended by health care professionals. Control of this disease depends on adherence to diabetes management, which includes monitoring blood glucose levels, adopting a healthy diet, exercising, taking medication, quitting smoking, and undergoing psychosocial care and periodic check-ups. This can also prevent health complications and reduce medical costs. Objective The objective of this study is to validate a culturally appropriate instrument directed towards the Mexican population that measures a patient's level of adherence to their type 2 diabetes mellitus management. Method The study design was cross-sectional. The instrument was applied individually (face to face researcher-assisted survey) by a member of the team. The study sample included 200 participants, which were attended at an outpatient clinic. To evaluate the psychometric validity of the scale we calculated response frequencies, the discrimination of items for extreme groups, the validity, and the internal reliability. The scale of adherence for complete management in patients with type 2 diabetes includes disease monitoring, complication prevention, and social support using questions and answers based on the Likert scale, corresponding to the 5 stages of the transtheoretical model. Main outcome measure The validity and internal reliability of the instrument to measure adherence to type 2 diabetes management, which proved to be justifiable and reliable with a Cronbach's alpha of 0.92 and a total explained variance of 65.03%. Results The instrument was composed of 29 items and 6 factors: adherence to medical Cronbach's alpha = 0.92 and dietary treatment Cronbach's alpha = 0.88, change in dietary habits Cronbach's alpha = 0.89, adherence to physical activity and exercise Cronbach's alpha = 0.84, social support Cronbach's alpha = 0.79, and prevention of complications Cronbach's alpha = 0.70. The instrument obtained a content validity index (I-CVI) of 0.9. Conclusion The proposed instrument, which includes factors that measure adherence in type 2 diabetes mellitus patient's management, using the transtheoretical model of behaviour change to simultaneously identify patient motivation to change their lifestyle, is valid and reliable.

Abstract
OBJECTIVE Two similarly designed studies compared user experiences with a second-generation extra-thin-wall, 5-bevel 32 G × 4 mm pen needle (PN) with redesigned hub versus four thinner commercially available PNs. METHODS Adults (18-75 years old) with type 1 or type 2 diabetes and ≥3 months of experience with pen injectors qualified for single-visit, single-blinded randomized studies. The investigational 32 G PN was compared with three 33-34 G × 3.5-4 mm PNs in Study 1 and one 34 G × 4 mm PN in Study 2. Participants completed 12 abdominal injections of 0.3 mL sterile saline using insulin pens in 6 pairs, each comprising one investigational 32 G PN and one comparator PN in random order. After each injection pair, participants compared injection pain via relative 150 mm visual analog scale (VAS) and perceived dose delivery force via relative 5 point Likert scale. Adjusted models tested injection pain scores (primary endpoint) for noninferiority and, if met, then for superiority. ClinicalTrials.gov identifiers: NCT03878758 and NCT03878745. RESULTS The investigational 32 G PN met noninferiority as well as superiority criteria for less injection pain vs. each comparator (p < .01), with adjusted mean relative VAS scores 9.1-17.6 in Study 1 (n = 154) and 7.3 in Study 2 (n = 55). The investigational 32 G PN was also superior vs. each comparator PN in requiring less relative perceived force to deliver the dose (p < .01). CONCLUSIONS The investigational 32 G PN was associated with less participant-reported injection pain and less perceived dose delivery force compared with four thinner PNs, suggesting no additional pain reduction or force reduction benefit conferred by the thinner PNs.

Abstract
AIMS Implementation of insulin therapy among those with diabetes is often suboptimal as a result of non-adherence or non-persistence. Studies regarding factors leading to insulin nonpersistence are limited. Therefore, we conducted this retrospective cohort study to determine the factors affecting insulin nonpersistence. METHODS A total of 274,852 persons with type 2 diabetes mellitus under insulin therapy during the period 2000-2014 were enrolled. Persons who stopped insulin therapy for >90 days were defined as having insulin nonpersistence. We searched for factors associated with insulin nonpersistence during the long-term follow-up period. RESULTS According to the multiple Cox regression model with a mean follow-up of 13.9 years, the factors associated with higher risk of insulin nonpersistence were age <40 years, men, residing in a rural area, Charlson comorbidity index score = 4, use of two or more oral antidiabetic drugs, and hypoglycemia during follow-up. The Kaplan-Meier graph showed that patients aged <40 years had significantly less insulin persistence. CONCLUSIONS This nationwide cohort study indicated that persons with young-onset type 2 diabetes, less medical resources, and more comorbidities are at risk of insulin nonpersistence. Healthcare providers should regularly assess insulin persistence and help patients who are having difficulty with insulin-taking.

Abstract
Understanding the benefits and risks of treatments to be used by older individuals (≥65 years old) is critical for informed therapeutic decisions. Glucose-lowering therapy for older patients with diabetes should be tailored to suit their clinical condition, comorbidities and impaired functional status, including varying degrees of frailty. However, despite the rapidly growing population of older adults with diabetes, there are few dedicated clinical trials evaluating glucose-lowering treatment in older people. Conducting clinical trials in the older population poses multiple significant challenges. Despite the general agreement that individualizing treatment goals and avoiding hypoglycaemia is paramount for the therapy of older people with diabetes, there are conflicting perspectives on specific glycaemic targets that should be adopted and on use of specific drugs and treatment strategies. Assessment of functional status, frailty and comorbidities is not routinely performed in diabetes trials, contributing to insufficient characterization of older study participants. Moreover, significant operational barriers and problems make successful enrolment and completion of such studies difficult. In this review paper, we summarize the current guidelines and literature on conducting such trials, as well as the learnings from our own clinical trial (IMPERIUM) that assessed different glucose-lowering strategies in older people with type 2 diabetes. We discuss the importance of strategies to improve study design, enrolment and attrition. Apart from summarizing some practical advice to facilitate the successful conduct of studies, we highlight key gaps and needs that warrant further research.

Abstract
OBJECTIVES To assess treatment discontinuation, associated factors and outcomes after initiating basal insulin (BI) among Chinese insulin-naïve patients with type 2 diabetes mellitus (T2DM) who had previously uncontrolled hyperglycaemia on OADs. PATIENTS Insulin-naïve patients with T2DM who had uncontrolled hyperglycaemia (HbA1c ≥7%) by OADs and were willing to initiate BI treatment were enrolled from 209 secondary and tertiary hospitals in eight geographical regions in China. DESIGN Each participant was interviewed at baseline, 3 and 6 months to collect study information. Patients with at least one visit during follow-up were included in the analyses. BI discontinuation was defined by a question asking whether the patient discontinued BI therapy at 3 or 6 months. Analyses were conducted to identify baseline factors associated with BI discontinuation and to estimate the association between insulin treatment discontinuation and patients' clinical outcomes at 6 months. RESULTS Of 17 858 patients, 25.8% discontinued basal insulin therapy within 6 months after initiation, and nearly two-thirds doing so within the first 3 months. Among patients discontinued basal insulin, 70.2% stopped all insulin therapy; 25.9% switched to premixed insulin and 3.8% switched to bolus only. Three most common reasons for BI discontinuation reported by patients were being unwilling to persist basal insulin without specific reasons (46.8%), reducing the frequency of daily injection (23.5%) and medical affordability (15.1%). Factors significantly associated with BI discontinuation were hospital level, patient recruitment setting, age, education level, out-of-pocket ratio, BMI, diabetes duration, self-monitoring of blood glucose (SMBG), numbers of OADs, BI type and insulin regimen. Compared with discontinuers, patients continued BI therapy had higher FPG (46.4% vs 28.8%) and HbA1c (42.3% vs 36.5%) control rate. CONCLUSION Among patients with T2DM who initiated BI therapy due to uncontrolled hyperglycaemia by OADs, the proportion of insulin discontinuation was high within 6 months. Further study is needed to understand the reason behind the BI discontinuation.

Abstract
OBJECTIVE A survey of US adults with type 2 diabetes mellitus was conducted to better understand patients' insulin initiation experiences and treatment persistence behaviors. RESEARCH DESIGN AND METHODS Participants were recruited from consumer panels and grouped by basal insulin treatment pattern: continuers (no gap of ≥7 days within 6 months of initiation); interrupters (gap ≥7 days, resumed treatment); discontinuers (stopped for ≥7 days, not resumed). A quota of approximately 50 respondents per persistence category was set. RESULTS A total of 154 respondents (52 continuers, 52 interrupters, 50 discontinuers) completed the survey. Mean age was 51.4 years; 51.9% male. Continuers were more likely to report their views being considered during initiation, and less likely to report a sense of failure. Concerns included insulin dependence (64.3% agree/strongly agree), frequent blood glucose monitoring (55.2%), costs/ability to pay (53.9%), fears of or mistakes during self-injection (52.6%), and weight gain (52.6%). Continuers were motivated by benefits of insulin therapy; experienced or potential side effects were notable factors for interruption/discontinuation. Healthcare provider instruction was indicated as a reason for continuing, stopping, and restarting therapy. CONCLUSION Benefits of basal insulin therapy motivated continuers while side effects impacted interruption/discontinuation. Persistence on basal insulin is often influenced by provider actions. Earlier provider intervention upon signs of treatment discontinuation may promote persistence.

Abstract
Delayed treatment intensification is common in U.S. patients with type 2 diabetes uncontrolled on basal insulin. Concerns about weight gain, hypoglycemia, increased regimen complexity, and additional copayments may lead to reluctance to initiate prandial insulin. IDegLira is a titratable, fixed-ratio coformulation that combines the advantages of insulin degludec and the glucagon-like peptide 1 receptor agonist liraglutide in a single once-daily injection and mitigates the side effects associated with each component. Clinical trials have demonstrated that IDegLira improves glycemic control without the increased risk of hypoglycemia and weight gain observed with basal insulin up-titration and the addition of prandial insulin, and this is achieved using twice-weekly titration. Clinical trials and real-world studies have also shown that IDegLira has the potential to reduce therapeutic and titration inertia. However, better outcomes could be achieved with IDegLira initiation in suitable patients with timely titration and by providers sharing their experience with this combination product. This review describes considerations for initiation, titration, and intensification of IDegLira in patients previously receiving basal insulin.

Abstract
OBJECTIVE Real-world effectiveness of basal insulin therapy is affected by poor treatment persistence, often occurring soon after initiation. This analysis is part of an international cross-sectional study conducted in T2DM patients and is intended to describe the reasons behind non-persistence to insulin therapy in Brasil. METHODS Responders to an online survey in seven countries were classified as continuers (no gap of ≥7 days), interrupters (interrupted therapy for ≥7 days within first 6 months, then restarted), and discontinuers (terminated therapy for ≥7 days within first 6 months, and did not start it again before the survey). We present the results from the Brazilian cohort. RESULTS Of 942 global respondents, 156 were from Brasil, with a mean age of 34 years and a mean of 5.8 years since T2DM diagnosis. Reasons contributing to insulin continuation (n=50) were improved glycemic control (82%) and improved physical feeling (50%). Common reasons for interruption (n=51) or discontinuation (n=55) were, respectively, weight gain (47.1%, 43.6%), hypoglycemia (45.1%, 38.2%), and pain from injections (39.2%, 49.1%). However, not all patients who reported weight gain and hypoglycemia as a reason for interruption or discontinuation experienced these: 16/24 (66.7%) and 22/24 (91.7%) participants had weight gain, and 13/23 (56.5%) and 15/21 (71.4%) had hypoglycemia, respectively. The most important reason for possible re-initiation for interrupters and discontinuers, respectively, was persuasion by the physician/HCP (80.4%, 72.7%). CONCLUSION The benefits of basal insulin therapy motivated continuers to persist with the treatment; experienced or anticipated side effects contributed to interruption and discontinuation. Physician and patient training is key in the treatment of diabetes.

Hypoglycaemia risk in the first 8 weeks of titration with insulin glargine 100 U/mL in previously insulin-naive individuals with type 2 diabetes mellitus. Diabetes Obes Metab 2018; 20:2894-2898. [PMID: 29943493 DOI: 10.1111/dom.13450] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2018] [Revised: 06/21/2018] [Accepted: 06/22/2018] [Indexed: 11/28/2022]
Abstract
Patient characteristics associated with hypoglycaemia frequency during insulin glargine 100 U/mL (Gla-100) titration and clinical outcomes at Week 24 were examined using participant-level data from 16 treat-to-target trials involving individuals with type 2 diabetes mellitus who were inadequately controlled with oral antidiabetes drugs and were initiating Gla-100 (n = 3549). Hypoglycaemia (plasma glucose <3.9 mmol/L or severe) during the first 8 weeks of titration was stratified by number of events (0, 1-3 and ≥4), resulting in 72.5%, 20.6% and 6.9% of participants in each group, respectively. Changes in glycaemia, body weight and insulin dose from baseline to Weeks 12 and 24 were analysed. Hypoglycaemia was more common in participants with lower BMI and fasting C-peptide, and in those undergoing sulfonylurea treatment. Glycaemic outcomes at Week 24 were similar in each hypoglycaemia group, despite the fact that the Week 24 mean daily dose and dose increase for Gla-100 were highest in participants without hypoglycaemia and were lowest in those experiencing ≥4 events. The risk of hypoglycaemia during Gla-100 titration depends mainly on patient characteristics and on sulfonylurea use and may delay dose titration, which apparently has little effect on short-term glycaemic control in a clinical trial setting.

Abstract
INTRODUCTION Persistence with basal insulin therapy can be suboptimal, despite recent improvements in insulin formulations and delivery systems. Patient support programs may help increase adherence. This study evaluated the impact of the Toujeo® COACH support program, which provides patients with continuing and individualized education and advice on lifestyle changes, by assessing its effect on number of refills and days on therapy. METHODS The study population included 1724 patients with diabetes who filled a first prescription for insulin glargine 300 U/mL (Gla-300) between April and December 2015 and received a welcome call from a Guide, and 1724 matched control patients from the Symphony Health Integrated Dataverse® prescription claims database. Control patients received Gla-300 but did not enroll in the program. These patients were matched based on age, gender, location, prior use of insulin, insulin dose, number of concomitant drugs, and copay tier. RESULTS The COACH and control groups comprised 52% men and 48% women; 22% were aged 18-47 years, 23% were 48-55 years, 27% 56-61 years, and 28% ≥ 62 years. Most (99%) had used insulin in the year before receiving the welcome call. At 6 months, patients in the COACH group had refilled their prescription 3.2 times on average, compared with 2.4 times for control patients (P < 0.0001); at 9 months, the average number of refills was 4.7 and 3.6, respectively (P < 0.0001). The average number of days on therapy at 6 months was 102.2 days in the COACH group and 81.5 days in the control group (P < 0.0001); at 9 months, the average number of days on therapy was 151.9 and 121.6, respectively (P < 0.0001). CONCLUSION Patients in the COACH program were significantly more likely to refill their prescriptions and stay on therapy. Patient support programs such as the COACH program could be an effective way to help improve diabetes care. FUNDING Sanofi US, Inc. and McKesson Corporation.

Abstract
Continuing use of medication is key to effective treatment and positive health outcomes, particularly in chronic conditions such as diabetes. However, in primary care, non-persistence (i.e. discontinuing or interrupting treatment) with insulin therapy is a common problem among patients with type 2 diabetes. To help primary care physicians manage patients who are non-persistent or likely not to be persistent, this review aimed to provide an overview of modifiable and non-modifiable factors associated with insulin non-persistence as well as practical strategies to address them. Data were extracted from published studies evaluating factors associated with non-persistence among patients with type 2 diabetes. A targeted literature review was performed using PubMed to identify recent studies (2000-2016) reporting measures of non-persistence with insulin therapy. Practical strategies to identify and prevent non-persistence were based on the authors' direct experience in primary care. Non-modifiable factors associated with non-persistence included gender, age, prior treatments, and cost of therapy. Before/at insulin initiation, modifiable factors included patients' perception of diabetes, preference for oral medication, and concerns/expectations about treatment complexity, inconvenience, or side effects. After initiation, modifiable factors included syringe use, difficulties during the first week of therapy, side effects, and insufficient glycemic control. Open-ended and patient-centered questions and a blame-free environment can help physicians identify, prevent, and reduce non-persistence behaviors. Possible questions to start a conversation with patients are provided. Effective physician-patient communication is essential to the management of diabetes. Primary care physicians should be familiar with the most common reasons for insulin non-persistence.
