Abstract
Background Adherence to medication in chronic conditions may be influenced by interventions from pharmacists. This study aimed to assess the impact of guidance and reminders from pharmacists on adherence to medication for hypertension, dyslipidemia, and chronic venous circulation disorders (CVCD) in Greece. Methods The prospective CONCORD study aimed to record and report on change in self-reported adherence to medication following pharmacist reminders amongst a cohort of adult patients, diagnosed with at least one or a combination of these health conditions. All study participants were regular patients of a network of pharmacies in Attica and southern Greece. Pharmacists were trained to provide adherence reminders over 4 months. Impact on self-reported adherence of the intervention was reported at baseline and again in month 4. Results Of the 1146 participants, 48% were men and 60% were aged 55-74 years. Among them, 23.7% were diagnosed with hypertension, 16.5% with dyslipidemia, 3% with CVCD, 42.5% with hypertension and dyslipidemia, 3.1% with hypertension and CVCD, 2.6% with dyslipidemia and CVCD, and 8.6% with dyslipidemia, hypertension, and CVCD. In month 4 vs month 0, patients were less likely to forget to take their prescribed medications (p<0.001), to be careless about their medications during the last 30 days (p<0.001), and to temporarily discontinue their medications without prior doctor's advice (p<0.001). Patients with CVCD were more prone to lower self-reported adherence compared to patients who were not diagnosed with CVCD or a combination of conditions that included CVCD. Discussion Reminders and advice from pharmacists resulted in higher adherence to medication amongst participants in month 4 versus month 0. Conclusion Pharmacist-enabled interventions, including reminders and advice, following targeted training, may positively impact on patient medication adherence in chronic health conditions.

Abstract
BACKGROUND Increasingly, patient medication adherence data are being consolidated from claims databases and electronic health records (EHRs). Such databases offer an indirect avenue to gauge medication adherence in our data-rich healthcare milieu. The surge in data accessibility, coupled with the pressing need for its conversion to actionable insights, has spotlighted data mining, with machine learning (ML) emerging as a pivotal technique. Nonadherence poses heightened health risks and escalates medical costs. This paper elucidates the synergistic interaction between medical database mining for medication adherence and the role of ML in fostering knowledge discovery. METHODS We conducted a comprehensive review of EHR applications in the realm of medication adherence, leveraging ML techniques. We expounded on the evolution and structure of medical databases pertinent to medication adherence and harnessed both supervised and unsupervised ML paradigms to delve into adherence and its ramifications. RESULTS Our study underscores the applications of medical databases and ML, encompassing both supervised and unsupervised learning, for medication adherence in clinical big data. Databases like SEER and NHANES, often underutilized due to their intricacies, have gained prominence. Employing ML to excavate patient medication logs from these databases facilitates adherence analysis. Such findings are pivotal for clinical decision-making, risk stratification, and scholarly pursuits, aiming to elevate healthcare quality. CONCLUSION Advanced data mining in the era of big data has revolutionized medication adherence research, thereby enhancing patient care. Emphasizing bespoke interventions and research could herald transformative shifts in therapeutic modalities.

Li H, Jia X, Min H, Zhang Y, Wang H, Zhai Y. Relationships between beliefs about statins and non-adherence in inpatients from Northwestern China: a cross-sectional survey. Front Pharmacol 2023; 14:1078215. [PMID: 37361205 PMCID: PMC10289550 DOI: 10.3389/fphar.2023.1078215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 05/31/2023] [Indexed: 06/28/2023] Open
Abstract
Background: Studies have identified patients' beliefs about medicines as an important determinant of non-adherence. However, scant data are available on the possible association between patients' beliefs and statin non-adherence among adult patients in China. The objectives of this study are to assess the prevalence of statin non-adherence, and to identify the factors associated with statin non-adherence, especially the association between inpatients' beliefs about statins and non-adherence in a tertiary hospital in the Northwestern China. Methods: A cross-sectional questionnaire-based survey was carried out in the department of cardiology and neurology between February and June 2022. The Beliefs about Medicine Questionnaire (BMQ) was used to assess patients' beliefs about statins. The Adherence to Refills and Medications Scale (ARMS) was used to assess statin adherence. Logistic regression analyses were performed to identify the factors associated with statin non-adherence. Receiver operator characteristic (ROC) was conducted to assess the performance of the logistic regression model in predicting statin non-adherence. Results: A total of 524 inpatients participated and finished the questionnaire, 426 (81.3%) inpatients were non-adherent to statin, and 229 (43.7%) inpatients expressed strong beliefs about the stain treatment necessity, while 246 (47.0%) inpatients expressed strong concerns about the potential negative effects. We found that the low necessity beliefs about statin (adjusted odds ratio [OR] and 95% confidence interval [CI], 1.607 [1.019, 2.532]; p = 0.041), prescribed rosuvastatin (adjusted OR 1.820 [1.124, 2.948]; p = 0.015) and ex-drinker (adjusted OR 0.254 [0.104, 0.620]; p = 0.003) were independent determinants of statin non-adherence. Conclusion: Statin adherence was poor in this study. The findings indicated a significant association between inpatients' lower necessity beliefs and statin non-adherence. More attention should be focused on statin non-adherence in China. Nurses and pharmacists could play an important role in patient education and patient counseling in order to improve medication adherence.

Abstract
PURPOSE Medication adherence plays an important role in glycemic control in type 2 diabetes mellitus (T2DM) self-management. To analyze the factors influencing medication adherence in T2DM patients and the effect of pharmacist-led interventions, we conducted a study in Beijing, China. PATIENTS AND METHODS T2DM patients with hypoglycemic drugs for at least 6 months were enrolled. A pharmacist-led survey was conducted followed by individualized interventions for those non-adherent patients monthly within 3 months. FPG, HbA1c, and 2hPG were measured as the comprehensive glycemic control. Medication adherence was determined according to the patient's self-reported compliance with prescribed medication during the last 3 months. RESULTS A total of 763 T2DM patients were included. The average age was 63.26±11.89 years, with 363 males. After pharmacist intervention, the patients with good adherence increased from 34.21% to 39.06%, while poor adherence decreased from 32.5% to 24.5% (p < 0.001). The average adherence score was a significant increase (p < 0.001) from 27.846±4.185 to 29.831±7.065. Furthermore, our study demonstrated that pharmacist-led interventions significantly increased glycemic control (FPG from 42.33% to 53.60%, p < 0.001; 2hPG from 41.68% to 48.75%, p = 0.005; HbA1c from 24.12% to 29.23%, p = 0.024). The results found that body mass index (OR 0.643, 95% CI 0.437-0.945), use of medications empirically (occasionally (OR=3.066, 95% CI 2.069-4.543); often (OR=2.984, 95% CI 1.107-8.044)), following the doctor's advice to visit (OR 2.129, 95% CI 1.079-4.202) and lifestyle compliance (OR 2.835, 95% CI 1.094-7.346) were the independent risk factors of non-adherence (p < 0.05), the area under the ROC curve was 0.716. CONCLUSION Self-reported medication adherence and glycemic control in T2DM patients were poor which can be improved by pharmacist-led interventions. Interventions should focus on empirical medication behavior, non-adherence to lifestyle, and failure to follow the doctor's advice. The recall bias with self-reported results needs further objective data to verify.

PATIENT EDUCATION AND COUNSELING 2022; 105:3381-3388. [PMID: 36002348 PMCID: PMC9675717 DOI: 10.1016/j.pec.2022.08.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 08/01/2022] [Accepted: 08/09/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE Clinical inertia, the absence of treatment initiation or intensification for patients not achieving evidence-based therapeutic goals, is a primary contributor to poor clinical outcomes. Effectively combating clinical inertia requires coordinated action on the part of multiple representatives including patients, clinicians, health systems, and the pharmaceutical industry. Despite intervention attempts by these representatives, barriers to overcoming clinical inertia in cardiovascular disease (CVD) risk factor control remain. METHODS We conducted a narrative literature review to identify individual-level and multifactorial interventions that have been successful in addressing clinical inertia. RESULTS Effective interventions included dynamic forms of patient and clinician education, monitoring of real-time patient data to facilitate shared decision-making, or a combination of these approaches. Based on findings, we describe three possible multi-level approaches to counter clinical inertia - a collaborative approach to clinician training, use of a population health manager, and use of electronic monitoring and reminder devices. CONCLUSION To reduce clinical inertia and achieve optimal CVD risk factor control, interventions should consider the role of multiple representatives, be feasible for implementation in healthcare systems, and be flexible for an individual patient's adherence needs. PRACTICE IMPLICATIONS Representatives (e.g., patients, clinicians, health systems, and the pharmaceutical industry) could consider approaches to identify and monitor non-adherence to address clinical inertia.

Abstract
Lack of medication adherence among patients with dyslipidemia negatively affects health-related outcomes. This study aims to evaluate medication adherence; we also aim to investigate the predictors of non-adherence among patients with dyslipidemia in Jordan. Medication adherence was evaluated in a total of 228 dyslipidemia patients. The Beliefs about Medicines Questionnaire was also used to assess patients' beliefs about medications. The majority of the current study participants (73.2%) reported non-adherence to the prescribed medications. There were significant negative associations between medication adherence and concerns of prescription drug use (B = -0.41, p-value < 0.01), duration of dyslipidemia (B = -0.22, p-value < 0.01), and the number of medications (B = -0.64, p-value < 0.01). Positive associations were found between medication adherence and the necessity of prescription drug use (B = 0.43, p-value < 0.01), taking statin and fibrate (B = 2.04, p-value < 0.01), and moderate-intensity statin (B = 2.34, p-value < 0.01). As for patients' beliefs about medications, the item "My medicine to lower my cholesterol disrupted my life" had the highest mean (3.50 ± 0.99). This study revealed a low adherence rate to medication among patients with dyslipidemia. It also demonstrates modifiable factors such as beliefs regarding perceived risk, medication harms, treatment duration, and the number of medications associated with poor adherence in patients with dyslipidemia.

Abstract
Background Dyslipidemia is one of the leading causes of cardiovascular complications in diabetes mellitus (DM) patients. Though it is a major public health problem in Ethiopia, there is no a nation-wide study to determine dyslipidemia among DM patients yet. Therefore, this systematic review and meta-analysis intended to estimate the prevalence of hypertriglyceridemia and other plasma lipid abnormalities among people living with DM in Ethiopia. Methods We systematically searched PubMed, Google Scholar, African Journals Online, Hinari, and direct Google. Studies conducted until May 9, 2020, that reports the prevalence of dyslipidemia among people living with DM were included. The DerSimonian and Laird random-effects model was used to determine the pooled prevalence of lipid profile abnormalities. Heterogeneity was checked using the I 2 statistic, whereas publication bias was tested by funnel plot and Egger's test. Besides, subgroup and sensitivity analyses were performed. Results We used 18 primary studies, including 4961 participants living with DM, which met the eligibility criteria for the meta-analysis of hypertriglyceridemia. The estimate of hypertriglyceridemia (≥150 mg/dl) was 48.15% (95% CI: 38.15-58.15, I 2 = 98.4%) after performing the main meta-analysis using the random-effects model. The subgroup analysis showed a higher pooled estimate of hypertriglyceridemia among T2DM (57.80% (95% CI: 50.50-65.10), I 2 = 92.5%), studies that used probability sampling technique (59.09% (95% CI: 43.58-74.59), I 2 = 98.6%, p < 0.001), and studies from primary data sources (51.43% (95% CI: 40.72-62.13), I 2 = 98.0%, p < 0.001). Moreover, the estimated pooled prevalence of the total plasma cholesterol (TC ≥ 200 mg/dl) was 34.08% (95% CI: 28.41-39.75, I 2 = 92.4%), LDL - C ≥ 100 mg/dl was 41.13% (95% CI: 27.15-55.11, I2 = 98.8%), and HDL ≤ 40 mg/dl for men and ≤ 50 mg/dl for women was 44.36% (95% CI: 31.82-56.90, I 2 = 98.8%). Conclusions The pooled prevalence of hypertriglyceridemia and other lipid abnormalities among DM patients was relatively high in Ethiopia. It strongly suggests the need to give maximal attention to the adherence of DM management to reduce the circulatory lipid profile abnormalities and subsequent complications. Prospero Registration.

Abstract
Objective The main aim of the study was to evaluate the patients' glycemic control and adherence to self-care tasks. Methods Patients with type 1 diabetes mellitus (T1DM) or latent autoimmune diabetes of the adult (LADA) using a multiple daily injection (MDI) regimen with carbohydrate counting (n = 25, Subgroup B) or fixed insulin dose (n = 25, Subgroup C) were allocated to use the application (app) for 12 weeks. Both subgroups were compared with each other and against a control group (n = 25, Group A) comprising patients with T1DM or LADA treated with continuous subcutaneous insulin infusion (CSII) in a parallel-group, open-label, clinical treatment trial. All patients had glycated hemoglobin (A1C) levels measured and were asked to fill out the Diabetes Self-Management Profile (DSMP) questionnaire at study start and end. The patients were instructed to measure capillary glucose six times daily in study weeks 4, 8, and 12. Results Mean A1C levels decreased 0.725% in Subgroup C in intragroup analysis (p = 0.0063), and had a mean variation of 0.834% compared with Group A (p = 0.003). Mean DSMP scores increased 5.77 points in Subgroup B in intragroup analysis (p = 0.0004) and increased by a mean of 6.815 points in relation to Group A (p = 0.002). Conclusion OneTouch Reveal improved both A1C levels and DSMP scores in patients with T1DM or LADA compared with standard treatment (CSII).

Abstract
BACKGROUND This study examined the association between quality of processes of diabetes care in terms of adherence to American Diabetes Association (ADA)-recommended guidelines and health care utilization in patients with diabetes. METHODS Adults with diabetes were identified from the pool of five panels of the Medical Expenditure Panel Survey, a nationally representative US sample, between 2012 and 2017. The Diabetes Care Survey was used to determine adherence to the ADA-recommended guidelines for processes of diabetes care if all of the following were performed annually: glycosylated hemoglobin check, foot examination, dilated eye examination, lipid panel, influenza immunization, blood pressure check, and dental examination. Health care utilization in terms of inpatient hospitalization, and emergency department (ED) and outpatient visits were estimated using two-part hurdle models. RESULTS An estimated 26.3 million adults with diabetes were derived from the pooled 5-panel data, of which 7.8% met the ADA-recommended guidelines for processes of diabetes care, and adherence rates of individual recommendations were generally below 50%. Overall, adults who adhered to the ADA-recommendations were older, non-Hispanic white, and married nonsmokers with private insurance and higher income. Mean inpatient hospital stays, ED, and outpatient visits between ADA-adherent vs nonadherent patients were 0.98 vs 1.62 (P < .001), 0.36 vs 0.39 (P = .074), and 17.9 vs 12.8 (P < .001), respectively. CONCLUSIONS Socioeconomic disadvantage and minority status were linked with nonadherence to the ADA-recommended processes of diabetes care. Adherence to the ADA recommendation was associated with significant reduction in inpatient hospitalization and a trend toward less ED visits. Our findings may apply to the United States and are likely to be different in other parts of the world.

Abstract
Hypertriglyceridemia refers to the presence of elevated concentrations of triglycerides (TG) in the bloodstream (TG >200 mg/dL). This lipid alteration is known to be associated with an increased risk of atherosclerosis, contributing overall to the onset of atherosclerotic cardiovascular disease (CVD). Guidelines for the management of hypertriglyceridemia are based on both lifestyle intervention and pharmacological treatment, but poor adherence, medication-related costs and side effects can limit the success of these interventions. For this reason, the search for natural alternative approaches to reduce plasma TG levels currently represents a hot research field. This review article summarizes the most relevant clinical trials reporting the TG-reducing effect of different food-derived bioactive compounds. Furthermore, based on the evidence obtained from in vitro studies, we provide a description and classification of putative targets of action through which several bioactive compounds can exert a TG-lowering effect. Future research may lead to investigations of the efficacy of novel nutraceutical formulations consisting in a combination of bioactive compounds which contribute to the management of plasma TG levels through different action targets.

Prevalence of Primary Non-adherence with Insulin and Barriers to Insulin Initiation in Patients with Type 2 Diabetes Mellitus - An Exploratory Study in a Tertiary Care Teaching Public Hospital. EUROPEAN ENDOCRINOLOGY 2020; 16:143-147.

Abstract
INTRODUCTION There is a paucity of data analysing the reasons for primary non-adherence following first prescription of insulin among patients with uncontrolled type 2 diabetes mellitus (T2DM) in India. To address this, and to attempt to understand these reasons, an exploratory study was undertaken to assess the prevalence of primary non-adherence with insulin and barriers to insulin initiation in these patients. METHODS Study participants were randomly selected from patients with T2DM who visited the diabetes clinic of a tertiary care teaching public hospital in Rishikesh, Uttarakhand, India, and were prescribed insulin for the first time in last 2-year period. All participants were evaluated for history of primary non-adherence, and those who were non-adherent were subsequently interviewed face-to-face using a modified, validated semi-structured questionnaire to identify the reasons for primary non-adherence. A focused group discussion was also conducted with eight physicians to elicit their views about reasons for primary non-adherence with insulin. RESULTS A total of 225 patients were identified and interviewed; of these, 105 were identified with a history of primary non-adherence and underwent a subsequent face-to-face interview. There was a high prevalence of primary non-adherence with insulin among the participants of this study. The main reasons for non-adherence were low self-efficacy, doubt about clinical benefits of insulin, fear of hypoglycaemia, needle phobia, unaffordability of insulin and blood glucose monitoring device, strong faith in alternative medicines and mythical ideologies, and fears of insulin being addictive and that it may cause rapid aging. CONCLUSION With the high prevalence of primary non-adherence, and the multitude of reasons for this, it is clear that we need to eliminate these barriers to treatment. Thus, provision of dedicated diabetes educators in each diabetes clinic and availability of cost-effective insulin and blood glucose monitoring devices for the underprivileged population are key to achieve this.

J Clin Nurs 2019; 29:909-921.

Abstract
AIMS AND OBJECTIVES The aim of this study was to identify the psychosocial determinants of adherence to oral antidiabetic medication, according to the Theory of Planned Behaviour (TPB). BACKGROUND Appropriate adherence to oral antidiabetic medication contributes to long-term glycaemic control. However, glycaemic control is often poor in people with type 2 diabetes, mainly due to the poor adherence to oral antidiabetic agents. DESIGN Prospective study with 2 waves of data collection, based on STROBE checklist was conducted. One hundred and fifty-seven adults with type 2 diabetes, in chronic use of oral antidiabetic agents, composed the sample. At baseline, self-reported measures of medication adherence (proportion and global evaluation of adherence) and of metabolic control (glycated haemoglobin) of diabetes were obtained. METHODS The TPB main constructs (attitude, subjective norm and perceived control) and related beliefs were measured. Adherence and metabolic control measurements were obtained in a two-month follow-up (n = 157). RESULTS Attitude and subjective norm, together, explained 30% of the variability in intention; their underlying belief-based measures (behavioural and normative beliefs) explained 28% of the variability in intention. In addition, intention predicted behaviour at follow-up. However, when added to the prediction model, past behaviour was the only explanatory factor of adherence behaviour. CONCLUSION Adherence behaviour to oral antidiabetic medication was predicted by intention, which, in turn, was determined by attitude and subjective norm. In order to promote adherence to oral antidiabetic agents, health professionals should include motivational strategies as well as strategies targeted to attitude and subjective norm when designing interventions. RELEVANCE TO CLINICAL PRACTICE The nonadherence to antidiabetic medication contributes to lack of control of diabetes and ensuing complications. The comprehension of the factors explaining the variability in medication adherence can inform the design of theory-based interventions aimed at promoting this behaviour.

Abstract
OBJECTIVE Self-report measures of medication nonadherence are frequently adapted to new clinical populations without evidence of validity. We evaluated the predictive validity of a medication nonadherence measure previously validated in patients with hypertension among patients taking cholesterol-reducing medications. METHOD This secondary analysis involves data from a randomized trial (VA HSR&D IIR 08-297) conducted at the Durham Veterans Affairs Medical Center. At baseline, 6-months, and 12-months, serum cholesterol was obtained and participants (n = 236) completed a 3-item measure of extent of nonadherence to cholesterol-reducing medications. Two cross-lagged panel models with covariates, in addition to growth curve analysis, were used to examine the predictive utility of self-reported nonadherence on concurrent and future cholesterol levels, while accounting for potential reverse-causation. RESULTS Extent of nonadherence items produced reliable scores across time and fit a single-factor model (CFI = 0.99). Nonadherence, and changes in nonadherence, moderately predicted future cholesterol values, and changes in cholesterol values (7 of 9 longitudinal associations were significant at p < .05; B's ranged from 0.16 to 0.35). Evidence for reverse associations was weaker (3 of 9 longitudinal associations were significant at p < .05; B's ranged from 0.16 to 0.36). CONCLUSION Analyses support the predictive validity of this medication nonadherence measure over the competing reverse-causation hypothesis.

Abstract
Adherence to antihyperglycemic medications is often suboptimal in patients with type 2 diabetes, and this can contribute to poor glycemic control, increased hospitalization, and the development of diabetic complications. Reported adherence rates to antihyperglycemics vary widely among studies, and this may be related to differences in methodology for measuring adherence, patient populations, and other factors. Poor adherence may occur regardless of the specific regimen used and whether therapy is oral or injectable, and can be especially common in chronic, asymptomatic conditions, such as type 2 diabetes. More convenient drug-administration regimens and advances in formulations and delivery devices are among strategies shown to improve adherence to antihyperglycemic therapy, especially for injectable therapy. This is exemplified by technological developments made in the drug class of glucagon-like peptide 1-receptor agonists, which are a focus of this narrative review. Dulaglutide, albiglutide, and prolonged-release exenatide have an extended duration of action and can be administered once weekly, whereas such agents as liraglutide require once-daily administration. The convenience of once-weekly versus once-daily administration is associated with better adherence in real-world studies involving this class of agent. Moreover, provision of a user-friendly delivery device has been shown to overcome initial resistance to injectable therapy among patients with type 2 diabetes. This suggests that recent innovations in drug formulation (eg, ready-to-use formulations) and delivery systems (eg, single-dose prefilled pens and hidden, ready-attached needles) may be instrumental in encouraging patient acceptance. For physicians who aim to improve their patients' adherence to antihyperglycemic medications, it is thus important to consider the patient's therapeutic experience (treatment frequency, drug formulation, delivery device). Better adherence, powered by recent technological advances in the delivery of glucagon-like peptide 1-receptor agonists, may thus lead to improved clinical outcomes in type 2 diabetes.

Abstract
Objective To analyzed the association of quality of life and compliance to drug treatment in chronic kidney disease patients. Methods The Short Form Health Survey was used to evaluate the quality of life of these patients, and the therapeutic complexity index was verified. The Morisky-Green test and the Brief Medication Questionnaire were applied to check compliance to drug therapy. Results A total of 197 patients were included. The Morisky-Green test and Brief Medication Questionnaire showed that most patients had low compliance to treatment (50.3% and 80.6%, respectively). Compliance was highly associated with gender (male) and slightly associated with complexity of therapy, mental health, and social aspects. Conclusion We observed a slight association between compliance to pharmacotherapy and quality of life and complexity of therapy, and a strong association with gender.

Abstract
Background High rates of inadequate health literacy are associated with maladaptive health outcomes in chronic disease including increased mortality and morbidity rates, poor treatment adherence and poor health. Adequate health literacy may be an important factor in the effective treatment and management of familial hypercholesterolemia, and may also be implicated in genetic screening for familial hypercholesterolemia among index cases. The present study examined the prevalence and predictors of health literacy in familial hypercholesterolemia patients attending clinics in seven countries. Design Cross-sectional survey. Methods Consecutive FH patients attending clinics in Australia, Brazil, China, Hong Kong, Malaysia, Taiwan and the UK completed measures of demographic variables (age, gender, household income and highest education level) and a brief three-item health literacy scale. Results Rates of inadequate health literacy were lowest in the UK (7.0%), Australia (10.0%), Hong Kong (15.7%) and Taiwan (18.0%) samples, with higher rates in the Brazil (22.0%), Malaysia (25.0%) and China (37.0%) samples. Income was an independent predictor of health literacy levels, accounting for effects of age. Health literacy was also independently related to China national group membership. Conclusions Findings indicate non-trivial levels of inadequate health literacy in samples of familial hypercholesterolemia patients. Consistent with previous research in chronic illness, inadequate health literacy is related to income as an index of health disparities. Chinese familial hypercholesterolemia patients are more likely to have high rates of inadequate health literacy independent of income. Current findings highlight the imperative of education interventions targeting familial hypercholesterolemia patients with inadequate health literacy.

Abstract
The prevalence of diabetes is steadily increasing in China. When diabetes is uncontrolled, it generates dire consequences for health and well-being. Numerous studies have shown that health outcomes were associated with social support and medication adherence. Previous study confirmed that social support was associated with medication adherence in patients with heart failure, HIV diseases, and first-episode psychosis. However, the relationship between social support and medication adherence in patients with type 2 diabetes mellitus (T2DM) is remains unclear. This study aims to examine whether social support is associated with medication adherence in patients with T2DM. This study was conducted in the First Affiliated Hospital of the General Hospital of the People’s Liberation Army (PLA). In Beijing, a systematic random sample of 412 patients with T2DM over 18 years was recruited at baseline, and demographic characteristics, clinical data and their assessment of social support were collected from medical records and self-reported questionnaires. 330 of these patients completed a self-report measure of medication adherence at the sixth month after baseline data collection. Regression analysis showed that social support presented a positive effect on medication adherence, additionally, support utilization and the subscale of social support exhibited a significantly strong influence on medication adherence in patients with T2DM. Although medication adherence was influenced by multiple factors, this finding confirmed that social support must be recognized as a core element in interventions aimed at improving in the management of patients with T2DM.

Abstract
Scholars and practitioners share a significant concern about rising healthcare costs. Health literacy is widely presented as a solution to this momentous issue, paving the way for a more appropriate access to care and therefore, for cost savings. However, to date little is still known about the ultimate effects of better health literacy on healthcare costs. Drawing from the findings of a systematic literature review which ultimately involved 29 papers retrieved from Scopus-Elsevier and PubMed. This manuscript is aimed at shedding light on the relationship between health literacy and healthcare costs. The inadequate ability of patients to understand health information and to navigate the healthcare system was found to be an important predictor of inappropriateness in the access to health care. In addition, people living with problematic health literacy are discouraged to be engaged in the provision of health services and are expected to show poor self-efficacy in dealing with their health-related conditions. From this point of view, poor health literate patients are assumed to be at high risk of exacerbation of their health problems, which in turn contributes in rising healthcare costs. In spite of these findings, both policy makers and practitioners seem to overlook the importance of health literacy. Eventually, the joint intervention on laws, policies, organizational strategies, and practices is crucial to handle the challenges related to limited health literacy.

Abstract
OBJECTIVE We studied a telemedicine intervention for persistent poorly controlled diabetes mellitus (PPDM) that combined telemonitoring, self-management support, and medication management. The intervention was designed for practical delivery using existing Veterans Affairs (VA) telemedicine infrastructure. To refine the intervention and inform the delivery of the intervention in other settings, we examined participants' experiences. METHODS We conducted semistructured interviews with 18 Veterans who completed the intervention. We analyzed interview text using directed content analysis and categorized themes by hemoglobin A1c (HbA1c) improvement (<1% or ≥1%). RESULTS Participants generally reported greater awareness of their blood glucose levels; however, they described dissatisfaction with the telemonitoring interface and competing demands during the intervention. Participants with <1% HbA1c improvement reported that these challenges interfered with their engagement. Participants with ≥1% HbA1c improvement reported new self-management routines despite challenges. CONCLUSION Despite competing demands and frustration with the telemonitoring interface, many participants demonstrated intervention engagement and substantial improvement in HbA1c ($1%). Differences in engagement may reflect differing capacity to manage treatment burden. Because it relies on existing infrastructure, this intervention is a promising model for addressing PPDM within VA. Future work should focus on optimizing systems' telemedicine infrastructure; while reliance on existing infrastructure may facilitate practical delivery, and it may also limit intervention engagement by excessively contributing to treatment burden.

Abstract
BACKGROUND Most people with diabetes are not attaining desirable levels of HbA1c (glycated haemoglobin), or of blood pressure and cholesterol, leaving them at risk of developing complications. AIM To identify ways of improving diabetes control by gaining insight into patients' attitudes/beliefs. DESIGN AND SETTING Questionnaires were offered to patients attending for a diabetes review in the 24 GP practices of North East Hampshire and Farnham Clinical Commissioning Group. METHOD Infrequent attenders were contacted by post. Volunteers then participated in focus groups. RESULTS Self-reported medication adherence was good with 83% (98/118) of responders recording ≥9 on a 10-point scale. Patients generally accepted they 'needed' and 'could take' medication. A substantial minority reported 'not liking' taking tablets. Focus groups confirmed this and revealed a reluctance to change lifestyle, with medication reported as a way to evade it. A total of 68 out of 112 responders (60.7%) knew their HbA1c value. However, focus groups identified little understanding of HbA1c, with responders perceiving it as medical jargon. Phrases such as 'stuck-on-sugar' or 'sugarload' were suggested as being semantically easier to understand. The questionnaire revealed trust in clinicians. This was confirmed in focus groups but confounded by frequent reports of healthcare providers giving inadequate/incorrect advice. CONCLUSION Investment in lifestyle change is needed. Participants were reluctant to change and saw medication as a way of avoiding it. HbA1c needs to be better explained. Intuitive phrases such as 'stuck-on-sugar' or 'sugarload' could be adopted into common parlance. Inadequate/incorrect advice seems to be hampering diabetes management and there appears to be a need for more diabetes-trained clinicians.

Abstract
Objective Many effective medical therapies are available for treating neurological diseases, but these therapies tend to be expensive and adherence is critical to their effectiveness. We used patient-reported data to examine the frequency and determinants of financial barriers to medication adherence among individuals treated for neurological disorders. Patients and methods Patients completed cross-sectional surveys on iPads as part of routine outpatient care in a neurology clinic. Survey responses from a 3-month period were collected and merged with administrative sources of demographic and clinical information (eg, insurance type). We explored the association between patient characteristics and patient-reported failure to refill prescription medication due to cost in the previous 12 months, termed here as “nonadherence”. Results The population studied comprised 6075 adults who were presented between July and September 2015 for outpatient neurology appointments. The mean age of participants was 56 (standard deviation: 18) years, and 1613 (54%) were females. The patients who participated in the surveys (2992, 49%) were comparable to nonparticipants with respect to gender and ethnicity but more often identified English as their preferred language (94% vs 6%, p<0.01). Among respondents, 9.8% (n=265) reported nonadherence that varied by condition. These patients were more frequently Hispanic (16.7% vs 9.8% white, p=0.01), living alone (13.9% vs 8.9% cohabitating, p<0.01), and preferred a language other than English (15.3% vs 9.4%, p=0.02). Conclusion Overall, the magnitude of financial barriers to medication adherence appears to vary across neurological conditions and demographic characteristics.

Abstract
Objective This study was designed to evaluate the correlation of baseline visual acuity (VA) with VA outcome in response to anti-vascular endothelial growth factor (VEGF) in diabetic macular edema using a retrospective analysis of nine clinical trials. The result will help assess the relevance of VA gain comparisons across trials. Methods A correlation analysis was performed between mean baseline VA and VA gain at month 12 for 1,616 diabetic macular edema patients across nine randomized clinical trials (RESOLVE, RISE, RIDE, RESTORE, RETAIN, DRCR.net Protocol I, DA VINCI, VIVID, VISTA) with anti-VEGF treatment regimens ranibizumab 0.5 mg and aflibercept 2 mg. Results The mean baseline VA ranged from 56.9 to 64.8 Early Treatment Diabetic Retinopathy Study (ETDRS) letters. The mean VA gain at month 12 ranged from 6.8 to 13.1 ETDRS letters across trials. There was a strong inverse correlation between mean baseline VA and VA gain at month 12 (r=−0.85). The mean VA at 12 months plateaued at ~70 (68.5–73.0) ETDRS letters (20/40 Snellen VA equivalent) for the anti-VEGF treatment groups from all trials, regardless of dosing regimens and agents. Conclusion Cross-trial comparisons based on changes in best-corrected visual acuity should be done cautiously and only after adjusting for best-corrected visual acuity at baseline. Furthermore, the total VA afforded by treatment appears to be subject to a plateau effect, which warrants further exploration.

Abstract
Due to the increasing prevalence of diabetes and the shortage of endocrinologists, family physicians have an important role in diabetes management. The purpose of this study was to examine the sources of knowledge, attitudes and practices of family physicians regarding the management of type 2 diabetes. Attendees at continuous medical education (CME) programs in Israel were requested to respond anonymously to written questions about their sources of knowledge about diabetes, the methods of diabetes management they advise their patients, their knowledge of diabetes medication treatments, and their attitudes toward people with type 2 diabetes. Questionnaires were completed by 362 family physicians (79% response rate). Of them, 329 (91%) reported that they usually manage their patients' diabetes care, including that of patients with concomitant risk factors. Their most common recommendations for diabetes control were: to increase physical activity, decrease total calorie intake, consult with a dietitian and undergo weight loss counseling. Almost all physicians (97%) reported providing lifestyle change counseling. Sixty percent reported lacking knowledge about nutritional issues. Only 58% answered correctly regarding the effect of the anti-diabetic drug, GLP1 analog. Board certified family physicians and their residents exhibited more knowledge about diabetes practice than did non-board certified family physicians. The great majority of family physicians surveyed usually manage their patients' diabetes themselves, and do not refer them to diabetes specialists. The implementation of strategies that will enhance the competencies and confidence of family physicians in diabetes management are important for achieving successful treatment.

Abstract
PURPOSE A comparatively high prevalence of comorbidities among African-American/Blacks (AA/B) has been implicated in disparate survival in breast cancer. There is a scarcity of data, however, if this effect persists when accounting for the adverse triple-negative breast cancer (TNBC) subtype which occurs at threefold the rate in AA/B compared to white breast cancer patients. METHODS We reviewed charts of 214 white and 202 AA/B breast cancer patients in the NCI-SEER Connecticut Tumor Registry who were diagnosed in 2000-2007. We employed the Charlson Co-Morbidity Index (CCI), a weighted 17-item tool to predict risk of death in cancer populations. Cox survival analyses estimated hazard ratios (HRs) for all-cause mortality in relation to TNBC and CCI adjusting for clinicopathological factors. RESULTS Among patients with SEER local stage, TNBC increased the risk of death (HR 2.18, 95 % CI 1.14-4.16), which was attenuated when the CCI score was added to the model (Adj. HR 1.50, 95 % CI 0.74-3.01). Conversely, the adverse impact of the CCI score persisted when controlling for TNBC (Adj. HR 1.49, 95 % CI 1.29-1.71; per one point increase). Similar patterns were observed in SEER regional stage, but estimated HRs were lower. AA/B patients with a CCI score of ≥3 had a significantly higher risk of death compared to AA/B patients without comorbidities (Adj. HR 5.65, 95 % CI 2.90-11.02). A lower and nonsignificant effect was observed for whites with a CCI of ≥3 (Adj. HR 1.90, 95 % CI 0.68-5.29). CONCLUSIONS comorbidities at diagnosis increase risk of death independent of TNBC, and AA/B patients may be disproportionately at risk.

Type D Personality Predicts Poor Medication Adherence in Chinese Patients with Type 2 Diabetes Mellitus: A Six-Month Follow-Up Study. PLoS One 2016; 11:e0146892.

Abstract
Background Type D personality and medication nonadherence have been shown to be associated with poor health outcomes. Type D personality is associated with poor medication adherence in patients with coronary artery disease, myocardial infarction, and heart failure. However, the relationship between type D personality and medication adherence in patients with Type 2 Diabetes Mellitus (T2DM) remains unknown. This study aims to examine whether type D personality was associated with medication adherence in patients with T2DM. Design and Settings A follow-up study was conducted in general hospital of the People's Liberation Army in Beijing. Methods 412 T2DM patients (205 females), who were recruited by circular systematic random sampling, provided demographic and baseline data about medical information and completed measures of Type D personality. Then, 330 patients went on to complete a self-report measure of medication adherence at the sixth month after baseline data collection. Chi-square test, t tests, and hierarchical multiple regression analyses were conducted, as needed. Results Patients with type D personality were significantly more likely to have poor medication adherence (p<0.001). Type D personality predicts poor medication adherence before and after controlling for covariates when it was analyzed as a categorical variable. However, the dimensional construct of type D personality was not associated with medication adherence when analyzed as a continuous variable. Conclusion Although, as a dimensional construct, type D personality may not reflect the components of the personality associated with poor medication adherence in patients with T2DM, screening for type D personality may help to identify those who are at higher risk of poor medication adherence. Interventions, aiming to improve medication adherence, should be launched for these high-risk patients.

Abstract
OBJECTIVES We investigated whether nonelderly US adults (aged 18-64 years) in food-insecure households are more likely to report cost-related medication underuse than the food-secure, and whether the relationship between food insecurity and cost-related medication underuse differs by gender, chronic disease, and health insurance status. METHODS We analyzed data from the 2011 and 2012 National Health Interview Survey (n = 67 539). We examined the relationship between food insecurity and cost-related medication underuse with the χ(2) test and multivariate logistic regression with interaction terms. RESULTS Bivariate and multivariate analyses showed a dose-response relationship between food insecurity and cost-related medication underuse, with an increasing likelihood of cost-related medication underuse with increasing severity of food insecurity (P < .001). This association was conditional on health insurance status, but not substantially different by gender or chronic disease status. Being female, low-income, having no or partial health insurance, chronic conditions, functional limitations, or severe mental illness were positively associated with cost-related medication underuse. CONCLUSIONS Using food insecurity as a risk factor to assess cost-related medication underuse could help increase identification of individuals who may need assistance purchasing medications and improve health for those in food-insecure households.

Abstract
The purpose of this study is to examine the relationship between food security and cost-related medication underuse among older adults (persons aged 65 years and older) in the United States; and to determine if this relationship differs by sex, chronic disease status, and type of health insurance. Data are from a combined sample of older adults in the 2011 and 2012 National Health Interview Survey (N = 10,401). Both bivariate and multivariate analyses show a dose-response relationship between food insecurity and cost-related medication underuse among the elderly--increasing likelihood of cost-related medication underuse with increasing severity of food insecurity (P < 0.001). This association is not conditional on sex, chronic disease status, or type of health insurance. However, females and those with a chronic condition are more likely to report cost-related medication underuse than males and those without a chronic condition respectively; and older adults with Medicare and Medicaid or other public insurance are less likely to report cost-related medication underuse than older adults with only Medicare.
