Abstract
The prevalence for chronic kidney disease (CKD) has steadily increased over the past decades. It is a gradually progressive disease that is associated with several comorbidities including cardiovascular diseases, hypertension, anemia, disorders of bone and mineral metabolism, electrolyte imbalance and acid-base abnormalities. All these comorbidities require adequate medication. Therefore, patients with CKD have a high risk for polypharmacy, which is defined as five or more medications daily. Polypharmacy causes a greatly increased risk for adverse drug effects and severe drug-drug interactions, which if not closely controlled and the individual doses adapted to the decreased renal function during the progression of the CKD, can result in increased morbidity and mortality. Therefore, several aspects of the medication need to be considered and constantly addressed. This article summarizes the problems arising from inadequate polypharmacy in CKD patients, including undesired adverse drug effects, drug interactions, the complexity of medication plans, treatment burden and nonadherence to the treatment. Furthermore, the most important steps to identify patients with inadequate polypharmacy are discussed, whereby complications can also be avoided and the benefits of the medication can be increased. Finally, the polypharmacy in acute kidney injury is dealt with.

A Narrative Review. Curr Hypertens Rep 2023; 25:353-363.

Abstract
PURPOSE OF REVIEW This narrative review aims to assess the pathophysiology, diagnosis, and treatment of resistant hypertension (RH) in end-stage kidney disease (ESKD) patients on dialysis, with a specific focus on the effect of renal denervation (RDN) on short-term and long-term blood pressure (BP) control. Additionally, we share our experience with the use of RDN in an amyloidotic patient undergoing hemodialysis with RH. RECENT FINDINGS High BP, an important modifiable cardiovascular risk factor, is often observed in patients in ESKD, despite the administration of multiple antihypertensive medications. However, in clinical practice, it remains challenging to identify RH patients on dialysis treatment because of the absence of specific definition for RH in this context. Moreover, the use of invasive approaches, such as RDN, to treat RH is limited by the exclusion of patients with reduced renal function (eGFR < 45 mL/min/1.73 m3) in the clinical trials. Nevertheless, recent studies have reported encouraging results regarding the effectiveness of RDN in stage 3 and 4 chronic kidney disease (CKD) and ESKD patients on dialysis, with reductions in BP of nearly up to 10 mmhg. Although multiple underlying pathophysiological mechanisms contribute to RH, the overactivation of the sympathetic nervous system in ESKD patients on dialysis plays a crucial role. The diagnosis of RH requires both confirmation of adherence to antihypertensive therapy and the presence of uncontrolled BP values by ambulatory BP monitoring or home BP monitoring. Treatment involves a combination of nonpharmacological approaches (such as dry weight reduction, sodium restriction, dialysate sodium concentration reduction, and exercise) and pharmacological treatments. A promising approach for managing of RH is based on catheter-based RDN, through radiofrequency, ultrasound, or alcohol infusion, directly targeting on sympathetic overactivity.

YI XUE BAN = JOURNAL OF CENTRAL SOUTH UNIVERSITY. MEDICAL SCIENCES 2023; 48:1066-1075. [PMID: 37724410 PMCID: PMC10930037 DOI: 10.11817/j.issn.1672-7347.2023.230045] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Indexed: 09/20/2023]
Abstract
OBJECTIVES Chronic kidney disease (CKD) patients with regular dialysis treatment for more than 3 months are called maintenance hemodialysis (MHD). The degree of patients' adherence with the doctor's advice to take medicine on time is called medication adherence, which is very important for the control of the disease and the improvement of the quality of life for MHD patients. Living alone, lack of communication with children and self-neglect are risk factors for medication adherence in the older adults. Inappropriate substance use behaviors are common among older adults with self-neglect. Family resilience denotes the ability of a family to retain the stability of its structure by relying on its internal and external resources when facing a difficult situation. Family resilience entails the combination of family beliefs, interaction styles, problem-solving skills, and emotional communication which reflect supportive and positive psychological adjustment effects to benefit older persons. This study aims to provide a theoretical basis for clinical intervention level to improve medication adherence of older patients on MHD through examineing the correlation among family resilience, self-neglect, and medication adherence based on the self-reports. METHODS A random sampling method was used to gather information from 632 older patients receiving MHD treatment in Hemodialysis Center of Hunan Province between July to December 2021. For this purpose, a self-designed demographic questionnaire, the Family Resilience Questionnaire (FRQ), the Scale of the Elderly Self-Neglect (SESN), and the Morisky Medication Adherence Scale-4 (MMAS-4) were used to investigate the questionnaire data of the participants. Pearson correlation was used to examine the relationship between family resilience, self-neglect, and medication adherence in older patients and gain insight into their current status. AMOS 24.0 was used for mediation modeling. Bootstrap mediation effect test was used to evaluate the mediation effect among the 3 variables. RESULTS The questionnaires survey showed that the scores of FRQ, SESN, and MMAS-4 were 78.60±12.49, 7.99±5.60, and 5.93±1.40, respectively; and the medication adherence rate was 18.8%. Pearson correlation analysis showed that family resilience was negatively correlated with self-neglect (r=-0.432, P<0.001), and was positively correlated with medication adherence (r=0.169, P<0.001). Self-neglect was negatively correlated with medication adherence (r=-0.217, P<0.001). Mediating effect analysis showed that the total effect of family resilience on medication adherence was significant (β=0.214, 95% CI 0.121 to 0.313, P<0.001), and the direct effect was not significant (β=0.058, 95% CI -0.073 to 0.187, P>0.05). Self-neglect played a major mediating effect between family resilience and medication adherence (β=0.156, 95% CI 0.088 to 0.240, P<0.001). CONCLUSIONS Family resilience, self-neglect, and medication adherence among older patients on MHD are significantly related, with family resilience primarily influencing medication adherence indirectly through self-neglect.

Qin W, Xu L. Pathways linking relative deprivation to blood pressure control: the mediating role of depression and medication adherence among Chinese middle-aged and older hypertensive patients. BMC Geriatr 2023; 23:57. [PMID: 36721087 PMCID: PMC9890848 DOI: 10.1186/s12877-023-03769-6] [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: 10/17/2022] [Accepted: 01/23/2023] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Studies have demonstrated that individuals of low socioeconomic status have higher blood pressure. Yet, whether socioeconomic inequality would influence blood pressure control and the underlying mechanisms associated with socioeconomic inequality in blood pressure control are unknown. Central to socioeconomic inequality is relative deprivation. We aim to examine the association between relative deprivation and blood pressure control and to investigate the pathways of the association among middle-aged and older adults with hypertension. METHODS Data were collected from the 2020 Household Health Interview Survey in Taian City, Shandong province. This study included 2382 eligible respondents aged 45 years and older with a diagnosis of hypertension. Our primary outcome was dichotomous blood pressure control. Relative deprivation was calculated with the Deaton Index. Depressive symptoms and medication adherence were considered as mediators. Multivariable binary logistic regression models were used to estimate the effect of relative deprivation on blood pressure control. The "KHB-method" was used to perform mediation analysis. RESULTS Among 2382 middle-aged and older adults with hypertension, the mean age was 64.9 years (SD 9.1), with 61.3% females. The overall proportion of participants with uncontrolled blood pressure was 65.1%. Increased relative deprivation was likely to have higher odds of uncontrolled blood pressure (OR: 2.35, 95%CI: 1.78-7.14). Furthermore, depressive symptoms and medication adherence partially mediated the overall association between relative deprivation and blood pressure control, with depressive symptoms and medication adherence explaining 5.91% and 37.76%, respectively, of the total effect of relative deprivation on blood pressure control. CONCLUSIONS Individual relative deprivation could threaten blood pressure control among middle-aged and older hypertension patients through the mechanisms of depression and medication adherence. Hence, improving blood pressure control may require more than just health management and education but fundamental reform of the income distribution and social security system to narrow the income gap, reducing relative economic deprivation. Additionally, interventions tailoring psychological services and medication adherence could be designed to reduce the harmful effect of relative deprivation on blood pressure control among disadvantaged individuals.

Cognitive impairment, perceived medication adherence, and high-risk medication use in patients with reduced kidney function: A cross-sectional analysis. Health Sci Rep 2022; 5:e697. [PMID: 35782299 PMCID: PMC9243633 DOI: 10.1002/hsr2.697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 05/06/2022] [Accepted: 05/31/2022] [Indexed: 11/18/2022] Open
Abstract
Background and Aims Reduced estimated glomerular filtration rate (eGFR < 60 ml/min/1.73 m2) is a risk factor for cognitive impairment (CI) and medication nonadherence. However, the association between CI and medication adherence in adults with reduced eGFR has not been adequately examined. Our pragmatic objectives were to assess the cross-sectional relationship between CI and self-reported medication adherence, medication number, and use of potentially high-risk medications among adults with reduced eGFR. Methods An observational cohort study of the epidemiology of CI in community-dwelling adults aged 45 years or older with reduced eGFR. Results Our analytic cohort consisted of 420 participants (202 with CI; mean age: 69.7 years) with reduced eGFR, at least one prescription medication, and nonmissing medication adherence data. Participants with CI had four times greater unadjusted odds of reporting good medication adherence than participants without CI (self-report of missing medications <4 days/month; odds ratio [OR]: 4.04, 95% confidence interval [CI]: 1.62-10.10). This difference persisted following adjustment for demographic factors and comorbidities (OR: 5.50, 95% CI: 1.86-16.28). Participants with CI were no more likely than participants without CI to report forgetfulness as a reason for missing medication doses. Participants with CI were, on average, taking more total (mean: 13.3 vs. 11.5, median: 12 vs. 11) and more high-risk (mean: 5.0 vs. 4.2, median: 5 vs. 4) medications than those without CI; these differences were attenuated and no longer significant following adjustment for demographics and comorbidities. Conclusion Given the well-documented association between CI and medication nonadherence, better self-reported medication adherence among those with CI may represent perceptions of adherence rather than actual adherence. Participants with CI were, on average, taking more total and more high-risk medications than those without CI, suggesting a possible increased risk for adverse drug events. Our results highlight the potential risks of relying on self-reported medication adherence in reduced eGFR patients with CI.

Abstract
OBJECTIVES Anemia is prevalent in hemodialysis (HD) patients. Data about factors associated with medication non-adherence in anemic HD patients is limited. This study examined determinants of medication non-adherence and its association with achievement of therapeutic goals of anemia measures among HD patients. METHODS A cross-sectional study was conducted among a representative group of HD patients in Jordan. Medication adherence was assessed using Morisky Green Levine Medication Adherence Scale (MGL). Other utilized instruments were modified Charlson Comorbidity Index (mCCI), general Health-Related Quality of Life (HRQoL) EQ-5D-5 L, and Hospital Anxiety and Depression Scale (HADS). Pharmacy claim data during the years of (2016-2017) were also retrieved from patients' medical records. Logistic regression was conducted to identify factors associated with medication non-adherence and achieving therapeutic goals of anemia therapy. RESULTS More than two-thirds of the participants (69.1%) were found non-adherent and the mean score of MGL scale was 2.4 ± 1.4. The non-adherence rate measured using refill data (69.6%) was comparable to that observed using self-reported MGL instrument. Education level of college or over was significantly associated with lower odds of non-adherence (OR = 0.365, p = 0.036), while complaining of a headache was associated with 2.5-fold risk of medication non-adherence (OR = 2.5, p = 0.017). A trend toward better achievement of iron indices therapeutic goals was observed with improved adherence measured using refill data. Multiple factors such as improved knowledge about prescribed medications was significantly associated with achieving anemia therapeutic goals (p < 0.05). CONCLUSION The findings suggest poor medication adherence among HD patients with anemia. Future interventions by health-care providers should target modifiable factors to improve medication adherence and, hence, health outcomes among HD patients with anemia.

Abstract
BACKGROUND High blood pressure is the most common chronic condition among US veterans. Blood pressure control is essential to preventing and managing cardiovascular diseases. While depressive symptoms are a known risk factor for uncontrolled blood pressure and veterans experience high rates of depressive symptoms, no research has examined the relationship between depressive symptoms and blood pressure control among US veterans. OBJECTIVE We examined whether moderately severe-to-severe depressive symptoms, compared to none-to-minimal, are associated with higher risk of uncontrolled blood pressure among US veterans. DESIGN We analyzed a population-based sample of veterans from the National Health and Nutrition Examination Survey (2013-2016). Logistic regression models were adjusted for marital status, age, and body mass index. All analyses were weighted; results are generalizable to US veterans. PARTICIPANTS A sample of 864 veterans was analyzed, representing approximately 18.8 million US veterans. MAIN MEASURES Depressive symptoms were assessed by the Patient Health Questionnaire-9. Uncontrolled blood pressure was defined as average systolic blood pressure ≥ 130 and/or diastolic blood pressure ≥ 80. KEY RESULTS For depressive symptoms, 78.2% (SE = 1.6) of US veterans had none-to-minimal, 18.2% (SE = 1.2) had mild-to-moderate, and 3.5% (SE = 0.8) had moderately severe-to-severe. Forty-three percent (SE = 3.0) of US veterans had uncontrolled blood pressure. Moderately severe-to-severe depressive symptoms, compared to none-to-minimal, were associated with lower risk for uncontrolled blood pressure (aOR = .28, 95% CI [.09, .85]). Mild-to-moderate depressive symptoms were not associated with blood pressure control (aOR = .98, 95% CI [.59, 1.65]). CONCLUSIONS US veterans with moderately severe-to-severe depressive symptoms were less likely to have uncontrolled blood pressure than veterans with none-to-minimal symptoms. Future research should examine factors unique to veterans that may explain findings opposite of the hypothesized relationship between depressive symptoms and blood pressure control.

Abstract
OBJECTIVES This systematic review aimed to describe medication non-adherence among people living with multimorbidity according to the current literature, and synthesise predictors of non-adherence in this population. METHODS A systematic review was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses. PubMed, EMBASE, CINAHL and PsycINFO were searched for relevant articles published in English language between January 2009 and April 2019. Quantitative studies reporting medication non-adherence and/or predictors of non-adherence among people with two or more chronic conditions were included in the review. A meta-analysis was conducted with a subgroup of studies that used an inclusive definition of multimorbidity to recruit participants, rather than seeking people with specific conditions. Remaining studies reporting prevalence and predictors of non-adherence were narratively synthesised. RESULTS The database search produced 10 998 records and a further 75 were identified through other sources. Following full-text screening, 178 studies were included in the review. The range of reported non-adherence differed by measurement method, at 76.5% for self-report, 69.4% for pharmacy data, and 44.1% for electronic monitoring. A meta-analysis was conducted with eight studies (n=8949) that used an inclusive definition of multimorbidity to recruit participants. The pooled prevalence of non-adherence was 42.6% (95% CI: 34.0 - 51.3%, k=8, I2=97%, p<0.01). The overall range of non-adherence was 7.0%-83.5%. Frequently reported correlates of non-adherence included previous non-adherence and treatment-related beliefs. CONCLUSIONS The review identified a heterogeneous literature in terms of conditions studied, and definitions and measures of non-adherence used. Results suggest that future attempts to improve adherence among people with multimorbidity should determine for which conditions individuals require most support. The variable levels of medication non-adherence highlight the need for more attention to be paid by healthcare providers to the impact of multimorbidity on chronic disease self-management.

Abstract
BACKGROUND Polypharmacy is common among patients with CKD, but little is known about the urinary excretion of many drugs and their metabolites among patients with CKD. METHODS To evaluate self-reported medication use in relation to urine drug metabolite levels in a large cohort of patients with CKD, the German Chronic Kidney Disease study, we ascertained self-reported use of 158 substances and 41 medication groups, and coded active ingredients according to the Anatomical Therapeutic Chemical Classification System. We used a nontargeted mass spectrometry-based approach to quantify metabolites in urine; calculated specificity, sensitivity, and accuracy of medication use and corresponding metabolite measurements; and used multivariable regression models to evaluate associations and prescription patterns. RESULTS Among 4885 participants, there were 108 medication-drug metabolite pairs on the basis of reported medication use and 78 drug metabolites. Accuracy was excellent for measurements of 36 individual substances in which the unchanged drug was measured in urine (median, 98.5%; range, 61.1%-100%). For 66 pairs of substances and their related drug metabolites, median measurement-based specificity and sensitivity were 99.2% (range, 84.0%-100%) and 71.7% (range, 1.2%-100%), respectively. Commonly prescribed medications for hypertension and cardiovascular risk reduction-including angiotensin II receptor blockers, calcium channel blockers, and metoprolol-showed high sensitivity and specificity. Although self-reported use of prescribed analgesics (acetaminophen, ibuprofen) was <3% each, drug metabolite levels indicated higher usage (acetaminophen, 10%-26%; ibuprofen, 10%-18%). CONCLUSIONS This comprehensive screen of associations between urine drug metabolite levels and self-reported medication use supports the use of pharmacometabolomics to assess medication adherence and prescription patterns in persons with CKD, and indicates under-reported use of medications available over the counter, such as analgesics.

Abstract
OBJECTIVE Medication non-adherence is a well-recognised issue in chronic diseases but data in patients with chronic kidney disease (CKD) not receiving kidney replacement therapy (KRT) remains limited. This review summarised the prevalence of medication non-adherence and assessed determinants and outcomes associated with it in adults with CKD, not on KRT. METHOD We searched PubMed, Embase, PsychInfo, Web of Science, and Cochrane (CENTRAL) for studies published until January 2020. Pooled prevalence of medication non-adherence was reported. Determinants of adherence-identified from quantitative and qualitative studies-were mapped into the theoretical domains framework and interventions proposed using the behavioural change wheel. RESULTS Twenty-seven studies (22 quantitative and 5 qualitative) were included. The pooled prevalence of medication non-adherence was 39% (95% CI 30-48%). Nine studies reported association between non-adherence and outcomes, including blood pressure, disease progression, adverse events, and mortality. Modifiable determinants of non-adherence were mapped into 11 of the 14 Theoretical Domains Framework-of which, six appeared most relevant. Non-adherence decisions were usually due to lack of knowledge on CKD, comorbidities, and medications; polypharmacy and occurrence of medication side effects; changes in established routines such as frequent medication changes; higher medication cost, poor accessibility to medications, services and facilities; inadequate patient-healthcare professional communication; and forgetfulness. Using the behavioural change wheel, we identified several areas where interventions can be directed to improve medication adherence. CONCLUSION Medication non-adherence is common in adults with CKD, not on KRT and may lead to poor outcomes. Evidence synthesis using mixed study designs was crucial in identifying determinants of non-adherence, drawing on a parsimonious approach from behaviour science. PROSPERO REGISTRATION CRD42020149983.

[PMID: 33589374 DOI: 10.1016/j.sapharm.2021.02.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 02/01/2021] [Accepted: 02/03/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND An adherence model is required to optimise medication management among chronic kidney disease (CKD) patients, as current assessment methods overestimate the true adherence of CKD patients with complex regimens. An approach to assess adherence to individual medications is required to assist pharmacists in addressing non-adherence. OBJECTIVE To develop an adherence prediction model for CKD patients. METHODS This multi-centre, cross-sectional study was conducted in 10 tertiary hospitals in Malaysia using simple random sampling of CKD patients with ≥1 medication (sample size = 1012). A questionnaire-based collection of patient characteristics, adherence (defined as ≥80% consumption of each medication for the past one month), and knowledge of each medication (dose, frequency, indication, and administration) was performed. Continuous data were converted to categorical data, based on the median values, and then stratified and analysed. An adherence prediction model was developed through multiple logistic regression in the development group (n = 677) and validated on the remaining one-third of the sample (n = 335). Beta-coefficient values were then used to determine adherence scores (ranging from 0 to 7) based on the predictors identified, with lower scores indicating poorer medication adherence. RESULTS Most of the 1012 patients had poor medication adherence (n = 715, 70.6%) and half had good medication knowledge (n = 506, 50%). Multiple logistic regression analysis determined 4 significant predictors of adherence: ≤7 medications (constructed score = 2, p < 0.001), ≤3 co-morbidities (constructed score = 1, p = 0.015), absence of complementary/alternative medicine use (constructed score = 1, p = 0.003), and knowledge score ≥80% (constructed score = 3, p < 0.001). A higher total constructed score from the prediction model indicated a higher likelihood of adherence (odds ratio [OR]: 2.41; 95% confidence interval [CI]: 2.112-2.744; p < 0.001). The area under the receiver operating characteristic (ROC) curve of the developed model (n = 677) had good accuracy (ROC: 0.867, 95% CI: 0.840-0.896; p < 0.001). The validated model (n = 335) also had good accuracy (ROC: 0.812, 95% CI: 0.765-0.859; p < 0.001). There was no significant difference between the development and validation groups (p = 0.11, Z-value:1.62, standard error: 0.034). CONCLUSION The score constructed from the medication adherence prediction model for CKD patients had good accuracy and could be useful for identifying patients with a higher risk of non-adherence, to ensure optimised adherence management.

Abstract
Randomized controlled trials on drug safety and effectiveness are the foundation of medical evidence, but they may have limited generalizability and be unpowered to detect rare and long-term kidney outcomes. Observational studies in routine care data can complement and expand trial evidence on the use, safety and effectiveness of medications and aid with clinical decisions in areas where evidence is lacking. Access to routinely collected large healthcare data has resulted in the proliferation of studies addressing the effect of medications in patients with kidney diseases and this review provides an introduction to the science of pharmacoepidemiology to critically appraise them. In this first review we discuss the concept and applications of pharmacoepidemiology, describing methods for drug-utilization research and discussing the strengths and caveats of the most commonly used study designs to evaluate comparative drug safety and effectiveness.

Abstract
Older adults with chronic kidney disease (CKD) often have many comorbidities, which requires them to take multiple medications. As the number of daily medications prescribed increases, the risk for polypharmacy increases. Understanding and improving medication adherence in this patient population is vital to avoiding the drug-related adverse events of polypharmacy. The primary objective of this review is to summarize the existing literature and to understand the factors leading to medication nonadherence in older patients with CKD. In this review, we discuss the prevalence of polypharmacy, the current lack of consensus on the incidence of medication nonadherence, the heterogeneity of assessing medication adherence, and the most common differential diagnoses for medication nonadherence in this population. Specifically, the most common differential diagnoses for medication nonadherence in older adults with CKD are (1) medication complexity; (2) cognitive impairment; (3) low health literacy; and (4) systems-based barriers. We provide tailored strategies to address these differential diagnoses and subsequently improve medication adherence. The clinical implications include deprescribing to decrease medication complexity and polypharmacy, utilizing a team-based approach to identify and support patients with cognitive impairment, enriching communication between health providers and patients with low health literacy, and improving health care access to address systems-based barriers. Further research is needed to determine the effects of addressing these differential diagnoses and medication adherence in older adults with CKD.

Abstract
Background: Multiple medications are required to effectively manage chronic kidney
disease (CKD) and associated complications, posing the risk of poor
medication adherence. Objectives: To measure medication adherence levels and to investigate the potential
predictors of sub-optimal medication adherence in pre-dialysis patients with
CKD. Methods: A prospective study was conducted in the medical and nephrology outpatients’
clinics in Maiduguri. Non-dialysis patients with CKD stages 1–4 aged
18 years and above were recruited through their physicians. The level of
medication adherence was determined using Morisky Medication Adherence
Scale. Descriptive statistics were used to summarize patients’ background
characteristics. Multivariate binary logistic regression analyses were
performed to investigate the significantly potential predictors of
sub-optimal medication adherence at a p < 0.05. Results: There were 107 participants (48.6%) who had high medication adherence, while
97 (44.1%), and 16 (7.3%) of them had moderate adherence, and low adherence,
respectively. The univariate analysis revealed that medication adherence
level differed significantly with the number of medications taken daily by
patients (p < 0.05). Multivariate logistic regression
analyses did not reveal a significant independent predictor of sub-optimal
medication adherence. Conclusion: A majority of the participants reported sub-optimal medication adherence. The
independent variables considered did not significantly predict sub-optimal
medication adherence in the study population. Nevertheless, the study
findings highlight the importance of clinical pharmacists’ CKD management
supportive care to help improve medication adherence.

Abstract
Rationale & Objective Group-based care provides an opportunity to increase patient access to providers without increasing physician time and is effective in the management of chronic diseases in the general population. This model of care has not been investigated in chronic kidney disease (CKD). Study Design Randomized controlled trial in adults (n = 50); observational study in adolescents (n = 10). Setting & Participants Adults and adolescents with CKD and hypertension in the Bronx, NY. Intervention Group-based care (monthly sessions over 6 months) versus usual care in adults. All adolescents received group-based care and were analyzed separately. Outcomes Participant attendance and satisfaction with group-based care were used to evaluate intervention feasibility. The primary clinical outcome was change in mean 24-hour ambulatory blood pressure. Secondary outcomes included physical activity, medication adherence, quality of life, and sodium intake as assessed by 24-hour urinary sodium excretion and food frequency questionnaires. Results Among adults randomly assigned to group-based care, attendance was high (77% of participants attended ≥3 sessions) and most reported higher satisfaction. Mean 24-hour ambulatory systolic blood pressure decreased by −4.2 (95% CI, −13.3 to 5.8) mm Hg in group-based care patients compared with usual care at 6 months but this was not statistically significant. Similarly, we did not detect significant differences in health-related behaviors (such as medication adherence, sodium intake, and physical activity) or quality-of-life measures between the 2 groups. Among the adolescents, attendance was very poor; self-reported satisfaction, although high, did not change from baseline compared with the 6-month follow-up. Limitations Small study size, missing data. Conclusions Group-based care is feasible and acceptable among adults with hypertension and CKD. However, a larger trial is needed to determine the effect on blood pressure and health-related behaviors. Patient participation may limit the effectiveness of group-based care models in adolescents.

Abstract
OBJECTIVES Patients with chronic kidney disease (CKD) are commonly treated with renin-angiotensin-aldosterone system inhibitors (RAASi) in order to delay progression of renal disease. However, research has shown that RAASi in CKD patients increases hyperkalaemia (HK) prevalence, which leads to RAASi discontinuation or dose reduction with the loss of benefits on the kidney. Patiromer is a novel therapy for HK treatment and may enable patients to remain on their RAASi regimen. This study aimed to assess the cost-effectiveness of patiromer from a Swedish healthcare perspective. METHODS A Markov model was developed to evaluate the economic outcomes of patiromer versus no patiromer in HK patients with stage 3-4 CKD taking RAASi. The model consisted of six health states reflecting disease progression and hospitalisations. The analysis mainly considered clinical data from the OPAL-HK trial and national costs. The main outcomes of interest were incremental costs (euro [EUR] 2016) and quality-adjusted life years (QALYs), discounted at 3%, and the incremental cost-effectiveness ratio (ICER). Extensive uncertainty analyses were performed. RESULTS In comparison to no patiromer, a patiromer patient gained 0.14 QALYs and an incremental cost of EUR 6109 (Swedish krona [SEK] 57,850), yielding an ICER of EUR 43,307 (SEK 410,072)/QALY gained. The results were robust to a range of sensitivity analyses. At a willingness-to-pay threshold of EUR 52,804 (SEK 500,000)/QALY, patiromer had a 50% chance of being cost-effective. CONCLUSIONS The results indicate that patiromer may demonstrate value for money in Swedish patients with stage 3-4 CKD, by enabling RAASi treatment. However, there is a considerable degree of uncertainty.

Abstract
BACKGROUND Medication adherence plays an essential role in slowing the progression of chronic kidney disease (CKD). This review aims to summarise factors affecting medication adherence among these pre-dialysis CKD patients. METHODS A systematic review of the literature was performed in Medline®, Embase®, SCOPUS® and CINAHL®. Peer-reviewed, English language articles which evaluated factors associated with medication adherence among pre-dialysis CKD patients were included. Meta-analysis was performed to assess the pooled medication adherence rates across studies. Factors identified were categorised using the World Health Organization's five dimensions of medication adherence (condition, patient, therapy, health-system, and socio-economic domains). RESULTS Of the 3727 articles reviewed, 18 articles were included. The pooled adherence rate across studies was 67.4% (95% CI 61.4-73.3%). The most studied medication class was anti-hypertensives (55.6%). A total of 19 factors and 95 sub-factors related to medication adherence were identified. Among condition-related factors, advanced CKD was associated with poorer medication adherence. Patient-related factors that were associated with lower medication adherence included misconceptions about medication and lack of perceived self-efficacy in medication use. Therapy-related factors which were associated with poorer medication adherence included polypharmacy while health system-based factors included loss of confidence in the physician. Socioeconomic factors such as poor social support and lower education levels were associated with poorer medication adherence. CONCLUSION Factors associated with poor medication adherence among pre-dialysis CKD patients were highlighted in this review. This will aid clinicians in designing interventions to optimise medication adherence among pre-dialysis CKD patients.

Abstract
This study examines the associations between medication adherence and burden, and health-related quality of life (HRQOL) in predialysis chronic kidney disease (CKD). A prospective study targeting adults with advanced CKD (estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m2) and not receiving renal replacement therapy was conducted in Tasmania, Australia. The actual medication burden was assessed using the 65-item Medication Regimen Complexity Index, whereas perceived burden was self-reported using a brief validated questionnaire. Medication adherence was assessed using a four-item Morisky-Green-Levine Scale (MGLS) and the Tool for Adherence Behaviour Screening (TABS). The Kidney Disease and Quality of Life Short-Form was used to assess HRQOL. Of 464 eligible adults, 101 participated in the baseline interview and 63 completed a follow-up interview at around 14 months. Participants were predominantly men (67%), with a mean age of 72 (SD 11) years and eGFR of 21 (SD 6) mL/min/1.73 m2. Overall, 43% and 60% of participants reported medication nonadherence based on MGLS and TABS, respectively. Higher perceived medication burden and desire for decision-making were associated with nonadherent behaviour. Poorer HRQOL was associated with higher regimen complexity, whereas nonadherence was associated with a decline in physical HRQOL over time. Medication nonadherence, driven by perceived medication burden, was prevalent in this cohort, and was associated with a decline in physical HRQOL over time.

Utilization of antihypertensive drugs among chronic kidney disease patients: Results from the Chinese cohort study of chronic kidney disease (C-STRIDE). J Clin Hypertens (Greenwich) 2020; 22:57-64. [PMID: 31816171 PMCID: PMC8030064 DOI: 10.1111/jch.13761] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Revised: 11/04/2019] [Accepted: 11/16/2019] [Indexed: 11/29/2022]
Abstract
The utilization of antihypertensive drugs plays an important role in blood pressure control among chronic kidney disease (CKD) patients. Limited information was available on how antihypertensive drugs were used among Chinese CKD patients. In the present study, the utilization of antihypertensive drugs among a subgroup of hypertensive participants with a complete record of antihypertensive drug information from the Chinese Cohort Study of Chronic Kidney Disease was analyzed. Among 2213 subjects, 61.7% and 26.5% had their blood pressure controlled to <140/90 mmHg and <130/80 mmHg, respectively. In total, 38.5% were on monotherapy. Of those patients who received combination therapy, 57.8% were treated with a two-drug combination. Renin-angiotensin system inhibitors (RASIs) were the most commonly prescribed drugs (71.2%). Only 10.2% of the patients were prescribed diuretics. After multivariable adjustment, participants taking RASI were more likely to have their blood pressure controlled to <140/90 mmHg (prevalence ratio (PR) 1.153, 95% confidence interval (CI): 1.071-1.240). CKD stage 4 (PR 0.548, 95% CI: 0.434-0.692) was associated with RASIs treatment. Additionally, diabetes (PR 1.498, 95% CI: 1.120-2.004), albumin/creatinine ratio ≥300 mg/g (PR 1.547, 95% CI: 1.020-2.344), and CKD stage 4 (PR 2.022, 95% CI: 1.223-3.343) were associated with diuretic use. The results suggested that combination therapy, diuretics use in general, and utilization of RASIs in advanced CKD stage were insufficient in the current treatment of Chinese hypertensive CKD patients.

Abstract
Chronic kidney disease (CKD) is an increasingly prevalent condition globally and is strongly associated with incident cardiovascular disease (CVD). Hypertension is both a cause and effect of CKD and affects the vast majority of CKD patients. Control of hypertension is important in those with CKD as it leads to slowing of disease progression as well as reduced CVD risk. Existing guidelines do not offer a consensus on optimal blood pressure (BP) targets. Therefore, an understanding of the evidence used to create these guidelines is vital when considering how best to manage individual patients. Non-pharmacological interventions are useful in reducing BP in CKD but are rarely sufficient to control BP adequately. Patients with CKD and hypertension will often require a combination of antihypertensive medications to achieve target BP. Certain pharmacological therapies provide additional BP-independent renoprotective and/or cardioprotective action and this must be considered when instituting therapy. Managing hypertension in the context of haemodialysis and following kidney transplantation presents further challenges. Novel therapies may enhance treatment in the near future. Importantly, a personalised and evidence-based management plan remains key to achieving BP targets, reducing CVD risk and slowing progression of CKD.

Abstract
OBJECTIVE The self-reported scale is a widely used method to assess patients' medication adherence in clinical practice, but there is still a lack of medicine adherence measurement scale for patients with Chronic Kidney Disease (CKD). Therefore, this study aimed to develop a medication adherence measurement scale of traditional Chinese medicine and Western medicine, providing a tool for evaluating medicine adherence of CKD patients. METHODS In the preliminary stage, we formed the prediction scale after three rounds Delphi method and it was filled by 20 patients, who were selected randomly. After pre-investigation and language adaption, we adjusted the prediction measurement scale which included 31 items based on Knowledge-Attitude-Belief Theory. Then, 222 CKD patients in Guangdong Hospital of traditional Chinese Medicine were investigated by this 31-item scale. We screened 31 items by Items analysis theory, including critical ratio, item correlation analysis, internal consistency analysis, principal component analysis and other methods. The left 26 items made up a formal scale. We collected and analyzed data of the 26-item scale and Chinese version of MGL scale, and took their scores correlation analysis as the criterion validity of the 26-item scale. At the same time, we evaluated content validity, Cronbach alpha coefficient and retest reliability of the 26-item scale. RESULTS We developed a scale with 26 items and 5 dimensions finally. In the validation analysis, the scale had good construct validity and content validity. The Pearson relation index between respective scores of the scale and Chinese version of MGL scale was 0.426, P<0.01. The scale also had good reliability as its 0.915 in Cronbach alpha, 0.753 in retest reliability and P<0.01. CONCLUSION The scale revealed great reliability and validity, which could be used as a measurement tool to evaluate the medication adherence of patients with CKD.

Considerable international variation exists in blood pressure control and antihypertensive prescription patterns in chronic kidney disease. Kidney Int 2019; 96:983-994. [PMID: 31358344 DOI: 10.1016/j.kint.2019.04.032] [Citation(s) in RCA: 52] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2018] [Revised: 04/09/2019] [Accepted: 04/22/2019] [Indexed: 11/26/2022]
Abstract
Although blood pressure control is a major goal in chronic kidney disease, no worldwide overview of either its achievement or antihypertensive prescriptions is currently available. To evaluate this we compared crude prevalence of uncontrolled blood pressure among 17 cohort studies, including 34 602 individuals with estimated glomerular filtration rate under 60 ml/min/1.73 m2 and treated hypertension across four continents, and estimated observed to expected prevalence ratios, adjusted for potential confounders. Crude prevalence of blood pressure of 140/90 mm Hg or more varied from 28% to 61% and of blood pressure of 130/80 or more from 54% to 84%. Adjusted prevalence ratios indicated poorer hypertension control than expected in cohorts from European countries, India, and Uruguay, and better control in patients from North American and high-income Asian countries. Four antihypertensive drug classes or more were prescribed to more than 30% of participants in North American and some European cohorts, but this practice was less common elsewhere. Renin angiotensin-aldosterone system inhibitors were the most common antihypertensive drugs, prescribed for 54% to 91% of cohort participants. Differences for other drug classes were much stronger, ranging from 11% to 79% for diuretics, 22% to 70% for beta-blockers, and 27% to 75% for calcium-channel blockers. The confounders studied explain only a part of the international variation in blood pressure control among individuals with chronic kidney disease. Thus, considerable heterogeneity in prescription patterns worldwide calls for further investigation into the impact of different approaches on patient outcomes.

Abstract
BACKGROUND Few studies have examined how adherence to antihypertensive medications varies across different regions or how neighborhood-level factors were related to individuals' medication-taking behaviors in patients. OBJECTIVE To explore local variation in medication adherence and examine environmental and individual influences on adherence to angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin-receptor blockers (ARBs) among elderly hypertensive patients with chronic kidney disease (CKD) in the United States. METHODS The Medicare 5% sample claim data (2006-2013), American Community Survey 5-Year Data (2005-2009) and the Health Resources and Services Administration Primary Care Service Area data (2007). The primary outcome was medication adherence, measured by Proportion of Days Covered (PDC). Geographically weighted regression (GWR) and linear mixed-effects models were used to investigate the relationship between environmental factors, individual risk factors and medication adherence. RESULTS A total of 70,201 hypertensive CKD patients residing in 2,981 counties of the US were selected. Significant spatial autocorrelation was observed in ACEIs/ARBs PDC. The West North Central and New England regions demonstrated higher adherence compared to the East South Central and West South Central regions. Residing in Medically Underserved Areas, counties with high deprivation scores, and not receiving Part D Low-income Subsidy were associated with poor medication adherence. CONCLUSIONS Medication adherence is geographically differentiated across the US. Environmental and individual factors identified may be helpful in the design of local interventions focused on improving patient outcomes from a population perspective.

Abstract
Abstract
Background
Haemodialysis patients experience a wide variety of intermediate complications, such as anaemia, hypertension and mineral bone disease (MBD). We aimed to assess the risk of death and hospital admissions as a function of the simultaneous attainment of different guideline targets (for hypertension, anaemia and MBD) in a large European cohort of dialysis patients.
Methods
EURODOPPS is part of the Dialysis Outcomes and Practice Patterns Study (DOPPS) international, prospective cohort study of adult, in-centre haemodialysis patients for whom clinical data are extracted from medical records. In the present analysis, 6317 patients from seven European countries were included between 2009 and 2011. The percentages of patients treated according to the international guidelines on anaemia, hypertension and MBD were determined. The overall degree of guideline attainment was considered to be high if four or all five of the evaluated targets were attained, moderate if two or three targets were attained, and low if fewer than two targets were attained. Fully adjusted multivariate Cox models were used to investigate the relationship of target attainment with mortality and first hospital admission.
Results
At baseline, the degree of target attainment was low in 1751 patients (28%), moderate in 3803 (60%) and high in 763 (12%). In the fully adjusted model using time-dependent covariates, low attainment was associated with higher all-cause mortality [hazard ratio (95% confidence interval) = 1.19 (1.05–1.34)] and high attainment was associated with lower all-cause mortality [0.82 (0.68–0.99)]. In a similar model that additionally accounted for death as a competing risk, low and high attainments were not associated with hospital admission.
Conclusion
In a large international cohort of dialysis patients, we have shown that more stringent application of guidelines is associated with lower mortality.

Abstract
BACKGROUND AND OBJECTIVES Short-term BP variability (derived from 24-hour ambulatory BP monitoring) and long-term BP variability (from clinic visit to clinic visit) are directly related to risk for cardiovascular events, but these relationships have been scarcely investigated in patients with CKD, and their prognostic value in this population is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In a cohort of 402 patients with CKD, we assessed associations of short- and long-term systolic BP variability with a composite end point of death or cardiovascular event. Variability was defined as the standard deviation of observed BP measurements. We further tested the prognostic value of these parameters for risk discrimination and reclassification. RESULTS Mean ± SD short-term systolic BP variability was 12.6±3.3 mm Hg, and mean ± SD long-term systolic BP variability was 12.7±5.1 mm Hg. For short-term BP variability, 125 participants experienced the composite end point over a median follow-up of 4.8 years (interquartile range, 2.3-8.6 years). For long-term BP variability, 110 participants experienced the composite end point over a median follow-up of 3.2 years (interquartile range, 1.0-7.5 years). In adjusted analyses, long-term BP variability was significantly associated with the composite end point (hazard ratio, 1.24; 95% confidence interval, 1.01 to 1.51 per 5-mm Hg higher SD of office systolic BP), but short-term systolic BP variability was not (hazard ratio, 0.92; 95% confidence interval, 0.68 to 1.25 per 5-mm Hg higher SD of 24-hour ambulatory systolic BP). Neither estimate of BP variability improved risk discrimination or reclassification compared with a simple risk prediction model. CONCLUSIONS In patients with CKD, long-term but not short-term systolic BP variability is related to the risk of death and cardiovascular events. However, BP variability has a limited role for prediction in CKD.

Abstract
BACKGROUND Drug-related problems (DRPs) are prevalent among chronic kidney disease (CKD) patients. However, little is known about their severity and management by community pharmacists. OBJECTIVES To (a) describe the prevalence of DRPs by severity level in CKD patients and (b) assess the effect of a training-and-communication network program in nephrology (ProFiL) on these DRPs. METHODS This is a secondary analysis of a cluster randomized controlled trial evaluating the effect of the ProFiL-program. In 6 CKD clinics, patients at CKD stage 3 or 4 and their community pharmacists were recruited and assigned to the ProFiL group or a usual care (UC) group. Using validated criteria, 2 pharmacists identified DRPs and assessed their severity at baseline and after 12 months. The mean annual change in the number of DRPs per patient by severity level was assessed using a 2-level multivariable linear mixed-effects model. RESULTS A total of 494 pharmacists and 442 patients participated. At baseline, the prevalence (mean number of DRPs per patient [SD]) of mild DRPs (e.g., requiring dosage adjustment) and moderate DRPs (e.g., drug adherence requiring a monitoring plan) were 0.55 (0.98) and 1.04 (1.51), respectively. After 12 months, an unadjusted incremental annual reduction of 0.34 moderate DRPs (95% CI = -0.66 to -0.01) was observed in the ProFiL group compared with the UC group. After adjustment, no between-group differences were observed. CONCLUSIONS Among patients followed in CKD clinics, most DRPs have a moderate severity requiring specific monitoring by pharmacists. The benefit of continuing education programs, such as ProFiL, to reduce moderate DRPs remains to be determined.

Abstract
We assessed the prevalence, awareness, treatment and control of hypertension in patients with moderate chronic kidney disease (CKD) under nephrological care in Germany. In the German Chronic Kidney Disease (GCKD) study, 5217 patients under nephrology specialist care were enrolled from 2010 to 2012 in a prospective observational cohort study. Inclusion criteria were an estimated glomerular filtration rate (eGFR) of 30-60 mL/min/1.73 m2 or overt proteinuria in the presence of an eGFR>60 mL/min/1.73 m2. Office blood pressure was measured by trained study personnel in a standardized way and hypertension awareness and medication were assessed during standardized interviews. Blood pressure was considered as controlled if systolic < 140 and diastolic < 90 mmHg. In 5183 patients in whom measurements were available, mean blood pressure was 139.5 ± 20.4 / 79.3 ± 11.8 mmHg; 4985 (96.2%) of the patients were hypertensive. Awareness and treatment rates were > 90%. However, only 2456 (49.3%) of the hypertensive patients had controlled blood pressure. About half (51.0%) of the patients with uncontrolled blood pressure met criteria for resistant hypertension. Factors associated with better odds for controlled blood pressure in multivariate analyses included younger age, female sex, higher income, low or absent proteinuria, and use of certain classes of antihypertensive medication. We conclude that blood pressure control of CKD patients remains challenging even in the setting of nephrology specialist care, despite high rates of awareness and medication use.

Risk Factors for Low Pharmacy Refill Adherence Among Older Hypertensive Men and Women by Race. Am J Med Sci 2018; 356:464-475. [PMID: 30384953 DOI: 10.1016/j.amjms.2018.07.007] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2018] [Revised: 07/12/2018] [Accepted: 07/23/2018] [Indexed: 01/13/2023]
Abstract
BACKGROUND Sex-race stratification may lead to identification of risk factors for low antihypertensive medication adherence that are not apparent when assessing risk factors in women and men without race stratification. We examined risk factors associated with low pharmacy refill adherence across sex-race subgroups (white women, black women, white men, black men) within the Cohort Study of Medication Adherence among Older Adults (n = 2,122). METHODS Pharmacy refill adherence was calculated as proportion of days covered using all antihypertensive prescriptions filled in the year prior to a baseline risk factor survey. Sex- and sex-race-stratified multivariable Poisson regression models with robust standard errors were used to estimate adjusted prevalence ratios and 95% confidence intervals for associations between participant characteristics and low adherence. RESULTS Prevalence of low adherence was 22.9% vs. 40.7% in white vs. black women (P < 0.001) and 26.3% vs. 37.2% in white vs. black men (P = 0.003). In multivariable models, reducing antihypertensive medication due to cost was associated with low adherence within each sex-race subgroup. Additional factors associated with low adherence included shorter hypertension duration and comorbidities in white women; not being married and depressive symptoms in white men; and ≥6 primary care visits/year and complementary and alternative medicine use in black men. Among men, not being married and reporting depressive symptoms were associated with low adherence for whites, but not blacks. CONCLUSIONS Identification of sex-race-specific risk factors for low antihypertensive medication adherence may guide development and implementation of tailored interventions to increase antihypertensive medication adherence and blood pressure control among older patients.

Abstract
The objective of this study was to assess the management practice, medication adherence, and factors affecting medication adherence in CKD patients at Tikur Anbessa Specialized Hospital (TASH). Methods. A cross-sectional study was conducted at the nephrology clinic of TASH. A total of 256 CKD (stages 1 and 2=50, stage 3=88, stage 4=55, and stage 5=63) patients were recruited through systematic random sampling. Data were collected from medical records and interviewing patients. The rate of adherence was determined using 8-item Morisky medication adherence scale. The data were analyzed using SPSS version 20.0 statistical software. Univariate and multivariate binary logistic regression were used to investigate the potential predictors of medication nonadherence. Results. About 57.3% of diabetes mellitus with hypertension were treated with combination of insulin and ACEI based regimens. Other cardiovascular comorbidities were predominantly treated with Acetyl Salicylic Acid in combination with β-blocker. Only 61.3% (stages 1 and 2=70%, stage 3=73.9%, stage 4=54.5%, and stage 5=43%) of the study population were adherent to their treatment regimens. Forgetfulness (79.8%) was the major reason for medication nonadherence. Patients who had an average and high monthly income were 4.14 (AOR=4.14, 95% CI: 1.45-11.84, p=0.008) and 6.17 times (AOR=6.17, 95% CI: 1.02-37.46, p=0.048) more likely to adhere as compared to those who had very low income. Patients who were prescribed with ≥5 drugs were 0.46 times (AOR= 0.54, 95% CI: 0.27-1.10, p=0.049) less likely to adhere compared to their counterpart. Patients who were students, drivers, or teachers working in private school were about 7.46 times (AOR=7.46, 95% CI: 1.49-37.26, p=0.014) more likely to adhere compared with patients who were farmers. Conclusion. Insulin and ACEIs based regimens were the most frequently used regimens in the treatment of diabetes mellitus and hypertension comorbidities. Very low income, increased number of prescribed medications, and being a farmer were the predictors of medication nonadherence.

Abstract
INTRODUCTION Chronic kidney disease (CKD) has a complicated interrelationship with other diseases and major risk factor for cardiovascular disease. Therapeutic management for CKD patients is complicated due to co-morbidities and dominant risk factors of CKD. Non-adherence to treatment is an increasing problem for patients with CKD and it has not been extensively studied in patients with CKD. Hence, the present study was carried out to assess the management practice, medication adherence and factors affecting medication adherence in CKD patients at Tikur Anbessa Specialized Hospital (TASH). METHODS A hospital-based cross-sectional study was conducted at the nephrology clinic of TASH. A total of 256 patients were recruited through systematic random sampling. Data were collected from medical records and interviewing patients. The degree of adherence was determined using eight-item Morisky Medication Adherence Scale. The data were entered into Epi Info 7.2.2.2 and analyzed using SPSS version 20.0 statistical software. Descriptive statistics such as frequency, percent, mean and standard deviation were used to summarize patients' baseline characteristics. Univariable and multivariable binary logistic regression were used to investigate the potential predictors of medication non-adherence. RESULTS About 55% patients with hypertension only were treated with non-angiotensin converting enzyme inhibition based regimens; 57.3% of diabetes mellitus with hypertension treated with combination of insulin and ACEI based regimens. About three-fourth of patients with anemia and osteodystrophy complications were treated with iron preparations and calcium based phosphate binder. Only 61.3% of the study population were adherent to their treatment regimens. Forgetfulness (79.8%) was the major reason for medication non-adherence. Patients who had an average and high monthly income were 4.14 (AOR = 4.14, 95% CI: 1.45-11.84, p = 0.008) and 6.17 times (AOR = 6.17, 95% CI: 1.02-37.46, p = 0.048) more likely to adhere as compared to those who had very low income. Patients who were prescribed with ≥5 drugs were 0.46 times (AOR = 0.54, 95% CI: 0.27-1.10, p = 0.049) less likely to adhere compared to their counterpart. Patients who were students, drivers, teachers working in private school were about 7.46 times (AOR = 7.46, 95% CI: 1.49-37.26, p = 0.014) more likely to adhere compared with patients who were farmers. CONCLUSION Insulin and ACEIs based regimens were the most frequently used regimens in the treatment of diabetes mellitus and hypertension co-morbidities. Very low income, increased number of prescribed medications and being a farmer were the predictors of medication non-adherence.

Abstract
BACKGROUND Multidisciplinary care (MDC) programs have been proposed as a way to alleviate the cost and morbidity associated with chronic kidney disease (CKD) in the US. METHODS AND FINDINGS We assessed the cost-effectiveness of a theoretical Medicare-based MDC program for CKD compared to usual CKD care in Medicare beneficiaries with stage 3 and 4 CKD between 45 and 84 years old in the US. The program used nephrologists, advanced practitioners, educators, dieticians, and social workers. From Medicare claims and published literature, we developed a novel deterministic Markov model for CKD progression and calibrated it to long-term risks of mortality and progression to end-stage renal disease. We then used the model to project accrued discounted costs and quality-adjusted life years (QALYs) over patients' remaining lifetime. We estimated the incremental cost-effectiveness ratio (ICER) of MDC, or the cost of the intervention per QALY gained. MDC added 0.23 (95% CI: 0.08, 0.42) QALYs over usual care, costing $51,285 per QALY gained (net monetary benefit of $23,100 at a threshold of $150,000 per QALY gained; 95% CI: $6,252, $44,323). In all subpopulations analyzed, ICERs ranged from $42,663 to $72,432 per QALY gained. MDC was generally more cost-effective in patients with higher urine albumin excretion. Although ICERs were higher in younger patients, MDC could yield greater improvements in health in younger than older patients. MDC remained cost-effective when we decreased its effectiveness to 25% of the base case or increased the cost 5-fold. The program costed less than $70,000 per QALY in 95% of probabilistic sensitivity analyses and less than $87,500 per QALY in 99% of analyses. Limitations of our study include its theoretical nature and being less generalizable to populations at low risk for progression to ESRD. We did not study the potential impact of MDC on hospitalization (cardiovascular or other). CONCLUSIONS Our model estimates that a Medicare-funded MDC program could reduce the need for dialysis, prolong life expectancy, and meet conventional cost-effectiveness thresholds in middle-aged to elderly patients with mild to moderate CKD.

Abstract
PURPOSE OF REVIEW The purposes of this review are to identify population characteristics of important risk factors for the development and progression of diabetic kidney disease (DKD) in the United States and to discuss barriers and opportunities to improve awareness, management, and outcomes in patients with DKD. RECENT FINDINGS The major risk factors for the development and progression of DKD include hyperglycemia, hypertension, and albuminuria. DKD disproportionately affects minorities and individuals with low educational and socioeconomic status. Barriers to effective management of DKD include the following: (a) limited patient and healthcare provider awareness of DKD, (b) lack of timely referrals of patients to a nephrologist, (c) low patient healthcare literacy, and (d) insufficient access to healthcare and health insurance. Increased patient and physician awareness of DKD has been shown to enhance patient outcomes. Multifactorial and multidisciplinary interventions targeting multiple risk factors and patient/physician education may provide better outcomes in patients with DKD.

Abstract
Introduction In the general population, medication nonadherence contributes to poorer outcomes. However, little is known about medication adherence among adults with chronic kidney disease (CKD). We evaluated the association of self-reported medication adherence with CKD progression and all-cause death in patients with CKD. Methods In this prospective observational study of 3305 adults with mild-to-moderate CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC) Study, the baseline self-reported medication adherence was assessed by responses to 3 questions and categorized as high, medium, and low. CKD progression (50% decline in eGFR or incident end-stage renal disease) and all-cause death were measured using multivariable Cox proportional hazards. Results Of the patients, 68% were categorized as high adherence, 17% medium adherence, and 15% low adherence. Over a median follow-up of 6 years, there were 969 CKD progression events and 675 deaths. Compared with the high-adherence group, the low-adherence group experienced increased risk for CKD progression (hazard ratio = 1.27, 95% confidence interval = 1.05, 1.54) after adjustment for sociodemographic and clinical factors, cardiovascular medications, number of medication types, and depressive symptoms. A similar association existed between low adherence and all-cause death, but did not reach standard statistical significance (hazard ratio = 1.14 95% confidence interval = 0.88, 1.47). Conclusion Baseline self-reported low medication adherence was associated with an increased risk for CKD progression. Future work is needed to better understand the mechanisms underlying this association and to develop interventions to improve adherence.

Abstract
Slowing down the progression of chronic kidney disease (CKD) and its adverse health outcomes requires the patient's self-management and attention to treatment recommendations. Information technology (IT)-based interventions are increasingly being used to support self-management in patients with chronic diseases such as CKD. We conducted a systematic review of randomized controlled trials (RCTs) to assess the features and effects of IT-based interventions on self-management outcomes of CKD patients. A comprehensive search was conducted in Medline, Scopus, and the Cochrane Library to identify relevant papers that were published until May 2016. RCT Studies that assessed at least one automated IT tool in patients with CKD stages 1 to 5, and reported at least one self-management outcome were included. Studies were appraised for quality using the Cochrane Risk of Bias assessment tool. Out of 12,215 papers retrieved, eight study met the inclusion criteria. Interventions were delivered via smartphones/personal digital assistants (PDAs) (three studies), wearable devices (three studies), computerized systems (one study), and multiple component (one study). The studies assessed 15 outcomes, including eight clinical outcomes and seven process of care outcomes. In 12 (80%) of the 15 outcomes, the studies had revealed the effects of the interventions as statistically significant positive. These positive effects were observed in 75% of the clinical outcomes and 86% of the process of care outcomes. The evidence indicates the potential of IT-based interventions (i.e. smartphones/PDAs, wearable devices, and computerized systems) in self-management outcomes (clinical and process of care outcomes) of CKD patients.

Abstract
BACKGROUND African Americans (AAs) suffer the widest gaps in chronic kidney disease (CKD) outcomes compared to Caucasian Americans (CAs) and this is because of the disparities that exist in both health and healthcare. In fact, the prevalence of CKD is 3.5 times higher in AAs compared to CAs. The disparities exist at all stages of CKD. Importantly, AAs are 10 times more likely to develop hypertension-related kidney failure and 3 times more likely to progress to kidney failure compared to CAs. SUMMARY Several factors contribute to these disparities including genetic and social determinants, late referrals, poor care coordination, medication adherence, and low recruitment in clinical trials. Key Messages: The development and implementation of CKD-related evidence-based approaches, such as clinical and social determinant assessment tools for medical interventions, more widespread outreach programs, strategies to improve medication adherence, safe and effective pharmacological treatments to control or eliminate CKD, as well as the use of health information technology, and patient-engagement programs for improved CKD outcomes may help to positively impact these disparities among AAs.

Trends in Antihypertensive Medication Discontinuation and Low Adherence Among Medicare Beneficiaries Initiating Treatment From 2007 to 2012. Hypertension 2016; 68:565-75. [PMID: 27432867 PMCID: PMC5215087 DOI: 10.1161/hypertensionaha.116.07720] [Citation(s) in RCA: 71] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2016] [Accepted: 06/16/2016] [Indexed: 11/16/2022]
Abstract
Low antihypertensive medication adherence is common. During recent years, the impact of low medication adherence on increased morbidity and healthcare costs has become more recognized, leading to interventions aimed at improving adherence. We analyzed a 5% sample of Medicare beneficiaries initiating antihypertensive medication between 2007 and 2012 to assess whether reductions occurred in discontinuation and low adherence. Discontinuation was defined as having no days of antihypertensive medication supply for the final 90 days of the 365 days after initiation. Low adherence was defined as having a proportion of days covered <80% during the 365 days after initiation among beneficiaries who did not discontinue treatment. Between 2007 and 2012, 41 135 Medicare beneficiaries in the 5% sample initiated antihypertensive medication. Discontinuation was stable during the study period (21.0% in 2007 and 21.3% in 2012; P-trend=0.451). Low adherence decreased from 37.4% in 2007 to 31.7% in 2012 (P-trend<0.001). After multivariable adjustment, the relative risk of low adherence for beneficiaries initiating treatment in 2012 versus in 2007 was 0.88 (95% confidence interval, 0.83-0.92). Low adherence was more common among racial/ethnic minorities, beneficiaries with Medicaid buy-in (an indicator of low income), and those with polypharmacy, and was less common among females, beneficiaries initiating antihypertensive medication with multiple classes or a 90-day prescription fill, with dementia, a history of stroke, and those who reached the Medicare Part D coverage gap in the previous year. In conclusion, low adherence to antihypertensive medication has decreased among Medicare beneficiaries; however, rates of discontinuation and low adherence remain high.

Abstract
BACKGROUND There is limited evidence of medication adherence related to progression of chronic kidney disease (CKD) worldwide. The aim of this study was to determine associations between medication adherence and the progression of CKD in outpatients with CKD. METHODS This cohort study recruited 339 Thai patients with stages 3-5 CKD. Patients with a glomerular disease or receiving renal replacement therapy before recruitment were excluded. 295 were followed up regarding their serum creatinine, blood pressure, glycated hemoglobin, and low-density lipoprotein cholesterol over 12 months. Medication adherence was measured at baseline using the Thai version of the 8-Item Morisky Medication Adherence Scale®. The primary outcome was the progression of CKD. The progression of CKD was defined as either a decline in estimated glomerular filtration rate of at least 3 ml/min/1.73 m2/year or initiation of renal replacement therapy. Univariate and multivariate analyses were performed using Chi-squared tests and multiple logistic regressions. RESULTS Twenty-one percent had poor adherence. Younger patients were more likely to have poor adherence (adjusted OR 2.81, 95 % CI 1.45-5.43). Anti-hypertensive agents were the most frequently reported as not being taken (52 %). Patients with poor adherence were associated with the progression of CKD (adjusted OR 1.96, 95 % CI 1.02-3.76). Those with poor adherence were less likely to control their blood pressure, than moderate-to-high adherence group (p < 0.01). CONCLUSION The findings suggest that CKD patients with poor medication adherence are more likely to have progression of CKD. Health care providers should acknowledge these findings and provide effective strategies to deal with this issue.

Abstract
Renal denervation is being used as a blood pressure lowering therapy for patients with apparent treatment resistant hypertension. However, this population does not represent a distinct disease condition in which benefit is predictable. In fact, the wide range in effectiveness of renal denervation could be a consequence of this heterogeneous pathogenesis of hypertension. Since renal denervation aims at disrupting sympathetic nerves surrounding the renal arteries, it seems obvious to focus on patients with increased afferent and/or efferent renal sympathetic nerve activity. In this review will be argued, from both a pathophysiological and a clinical point of view, that chronic kidney disease is particularly suited to renal denervation.

Abstract
BACKGROUND Patients with chronic kidney disease initiating an antihypertensive drug (AH) treatment must persist and comply with it to slow disease progression and benefit from the reduction of cardiovascular morbidity and mortality. OBJECTIVES This study evaluates the persistence and compliance with AH treatment and identifies the associated factors among chronic kidney disease patients who initiated AH treatment. METHODS A population-based cohort study using Quebec administrative data was conducted. Patients who still take any AH 1 year after initiation were considered persistent. Of these patients, those who had ≥80% of days covered with an AH in the year after initiation were considered compliant. Factors associated with persistence and compliance were identified using a modified Poisson regression. RESULTS Of the 7,119 eligible patients, 78.8% were persistent, 87.7% of whom were compliant with their AH treatment. Compared with patients on diuretic monotherapy, those who initially used angiotensin-converting enzyme inhibitor monotherapy, angiotensin II receptor blocker monotherapy, calcium channel blocker monotherapy, β-blocker monotherapy, or multidrug therapy were more likely to be persistent. In contrast, individuals who visited their physicians ≥17 times were less likely to be persistent than those who visited between 0 and 8 times. The patients who were more likely to be compliant had initially used an angiotensin-converting enzyme inhibitor, β-blocker, calcium channel blocker, or multitherapy as opposed to a diuretic. CONCLUSION A year after initiating AH treatment, nearly a third of chronic kidney disease patients were either not taking an AH or had not been compliant. Factors associated with persistence and compliance could help identify patients who need help in managing their AH treatment.

Abstract
BACKGROUND Promoting medication adherence is a recognized challenge for prescribers. In this study, we examine whether lower medication adherence is associated with adverse safety events in individuals with decreased estimated glomerular filtration rates (eGFRs). STUDY DESIGN Cross-sectional baseline analysis of prospective cohort. SETTING & PARTICIPANTS Baseline analysis of the Safe Kidney Care (SKC) Cohort Study, a prospective study of individuals with eGFRs<60 mL/min/1.73 m(2) intended to assess the incidence of disease-specific safety events. Kidney transplant recipients were excluded. PREDICTOR Self-reported medication adherence based on responses to 3 questions ascertaining degree of medication regimen adherence. OUTCOMES Adverse safety events were self-reported at baseline (class I events), such as hypoglycemia or fall thought to be related to a medication, or detected incidentally during the baseline visit (class II events), for example, hypotension or hyperkalemia. Potential drug-related problems (DRPs) were determined by analyzing participants' medications with respect to dosing guidelines based on their screening eGFRs at the time of medication reporting. MEASUREMENTS Relationship between medication adherence and disease-specific patient safety events. RESULTS Of 293 SKC participants, 154 (53%) were classified as having lower medication adherence. After multivariable adjustment, lower medication adherence was significantly associated with a class I or II safety event (prevalence ratio [PR], 1.21; 95% CI, 1.04-1.41) and potential DRPs (PR, 1.29; 95% CI, 1.02-1.63). Lower medication adherence was also significantly associated with multiple (≥2) class I events (PR, 1.71; 95% CI, 1.18-2.49), multiple class I or II events (PR, 1.35; 95% CI, 1.04-1.76), and multiple potential DRPs (PR, 2.11; 95% CI, 1.08-2.69) compared with those with higher medication adherence. LIMITATIONS Use of self-reported medication adherence rather than pharmacy records. Clinical relevance of detected safety events is unclear. CONCLUSIONS Lower medication adherence is associated with adverse safety events in individuals with eGFRs<60 mL/min/1.73 m(2).

Medication adherence and visit-to-visit variability of systolic blood pressure in African Americans with chronic kidney disease in the AASK trial. J Hum Hypertens 2015; 30:73-8.

Abstract
Lower adherence to antihypertensive medications may increase visit-to-visit variability of blood pressure (VVV of BP), a risk factor for cardiovascular events and death. We used data from the African American Study of Kidney Disease and Hypertension (AASK) trial to examine whether lower medication adherence is associated with higher systolic VVV of BP in African Americans with hypertensive chronic kidney disease (CKD). Determinants of VVV of BP were also explored. AASK participants (n=988) were categorized by self-report or pill count as having perfect (100%), moderately high (75-99%), moderately low (50-74%) or low (<50%) proportion of study visits with high medication adherence over a 1-year follow-up period. We used multinomial logistic regression to examine determinants of medication adherence, and multivariable-adjusted linear regression to examine the association between medication adherence and systolic VVV of BP, defined as the coefficient of variation or the average real variability (ARV). Participants with lower self-reported adherence were generally younger and had a higher prevalence of comorbid conditions. Compared with perfect adherence, moderately high, moderately low and low adherence was associated with 0.65% (±0.31%), 0.99% (±0.31%) and 1.29% (±0.32%) higher systolic VVV of BP (defined as the coefficient of variation) in fully adjusted models. Results were qualitatively similar when using ARV or when using pill counts as the measure of adherence. Lower medication adherence is associated with higher systolic VVV of BP in African Americans with hypertensive CKD; efforts to improve medication adherence in this population may reduce systolic VVV of BP.

Abstract
REasons for Geographic and Racial Differences in Stroke (REGARDS) is a longitudinal study supported by the National Institutes of Health to determine the disparities in stroke-related mortality across USA. REGARDS has published a body of work designed to understand the disparities in prevalence, awareness, treatment, and control of coronary heart disease (CHD) and its risk factors in a biracial national cohort. REGARDS has focused on racial and geographical disparities in the quality and access to health care, the influence of lack of medical insurance, and has attempted to contrast current guidelines in lipid lowering for secondary prevention in a nationwide cohort. It has described CHD risk from nontraditional risk factors such as chronic kidney disease, atrial fibrillation, and inflammation (i.e., high-sensitivity C-reactive protein) and has also assessed the role of depression, psychosocial, environmental, and lifestyle factors in CHD risk with emphasis on risk factor modification and ideal lifestyle factors. REGARDS has examined the utility of various methodologies, e.g., the process of medical record adjudication, proxy-based cause of death, and use of claim-based algorithms to determine CHD risk. Some valuable insight into less well-studied concepts such as the reliability of current troponin assays to identify "microsize infarcts," caregiving stress, and CHD, heart failure, and cognitive decline have also emerged. In this review, we discuss some of the most important findings from REGARDS in the context of the existing literature in an effort to identify gaps and directions for further research.

Abstract
The US Health Care System provides a patchwork of services, known as the safety net, for the uninsured, underinsured, and indigent populations who would otherwise have little access to health care services. Individuals who rely on safety-net facilities are from racial/ethnic minority groups, have low socioeconomic status, and often have low health literacy and/or limited English proficiency. They shoulder a disproportionate burden of CKD in the United States and experience excess CKD-associated morbidity and mortality. Suboptimal delivery of CKD care may be contributing and is an area of active translational research. Several initiatives that show promise in improving safety-net CKD care delivery include those that enhance diagnostic and management skills of primary care providers, rely on comprehensive care management programs led by nonphysicians, and leverage technology to enhance patient access to virtual nephrology expertise. Uncovering better ways to translate scientific evidence into practice for vulnerable patients with CKD is a formidable challenge that will require national surveillance of CKD quality measures across diverse ambulatory health systems, including safety nets. Only then will the nephrology community be to identify and share best practices to enhance health and mitigate disparities of care among patients with CKD.

Abstract
Background Early detection and effective management of risk factors can potentially delay progression of chronic kidney disease (CKD) to end-stage kidney disease, and decrease mortality and morbidity from cardiovascular (CV) disease. We evaluated a specialist nurse-led intervention in the primary care setting to address accepted risk factors in a study sample of adults at ‘high risk of CKD progression’, defined as uncontrolled type II diabetes and/or hypertension and a history of poor clinic attendance. Methods The study was a non-controlled quality improvement study with pre- and post- intervention comparisons to test feasibility and potential effectiveness. Patients within two primary care practices were screened and recruited to the study. Fifty-two patients were enrolled, with 36 completing 12-months follow-up. The intervention involved a series of sessions led by the nephrology Nurse Practitioner with assistance from practice nurses. These sessions included assessment, education and planned medication and lifestyle changes. The primary outcome measured was proteinuria (ACR), and the secondary outcomes estimated glomerular filtration rate (eGFR) and 5-year absolute CV risk. Several ‘intermediary’ secondary outcomes were also measured including: blood pressure, serum total cholesterol, glycosylated haemoglobin (HbA1c), body mass index (BMI), prevalence of active smoking, a variety of self-management domains, and medication prescription. Analysis of data was performed using linear and logistic regression as appropriate. Results There was a significant improvement in ACR (average decrease of −6.75 mg/mmol per month) over the course of the study. There was a small but significant decrease in eGFR and a reduction in 5 year absolute CV risk. Blood pressure, serum total cholesterol, and HbA1c all decreased significantly. Adherence to lifestyle advice improved with a significant reduction in prevalence of active smoking, although there was no significant change in BMI. Self-management significantly improved across all relevant domains. Conclusions The results suggest that a collaborative model of care between specialist renal nurses and primary care clinicians may improve the management of risk factors for progression of CKD and CV death. Further larger, controlled studies are warranted to definitively determine the effectiveness and costs of this intervention.

Abstract
Poor long-term adherence and persistence to drug therapy is universally recognized as one of the major clinical issues in the management of chronic diseases, and patients with renal diseases are also concerned by this important phenomenon. Chronic kidney disease (CKD) patients belong to the group of subjects with one of the highest burdens of daily pill intake with up to >20 pills per day depending on the severity of their disease. The purpose of the present review is to discuss the difficulties encountered by nephrologists in diagnosing and managing poor adherence and persistence in CKD patients including in patients receiving maintenance dialysis. Our review will also attempt to provide some clues and new perspectives on how drug adherence could actually be addressed and possibly improved. Working on drug adherence may look like a long and tedious path, but physicians and healthcare providers should always be aware that drug adherence is in general much lower than what they may think and that there are many ways to improve and support drug adherence and persistence so that renal patients obtain the full benefits of their treatments.

Abstract
Background We examined the psychometric properties of the Korean version of the 8-item Morisky Medication Adherence Scale (MMAS-8) among adults with hypertension. Methods A total of 373 adults with hypertension were given face-to-face interviews in 2 cardiology clinics at 2 large teaching hospitals in Seoul, South Korea. Blood pressure was measured twice, and medical records were reviewed. About one-third of the participants (n = 109) were randomly selected for a 2-week test-retest evaluation of reliability via telephone interview. Results Internal consistency reliability was moderate (Cronbach α = 0.56), and test-retest reliability was excellent (intraclass correlation = 0.91; P < 0.001), although a ceiling effect was detected. The correlation of MMAS-8 scores with scores for the original 4-item scale indicated that convergent validity was good (r = 0.92; P < 0.01). A low MMAS-8 score was significantly associated with poor blood pressure control (χ2 = 29.86; P < 0.001; adjusted odds ratio = 5.08; 95% CI, 2.56–10.08). Using a cut-off point of 6, sensitivity and specificity were 64.3% and 72.9%, respectively. Exploratory factor analysis identified 3 dimensions of the scale, with poor fit for the 1-dimensional construct using confirmatory factory analysis. Conclusions The MMAS-8 had satisfactory reliability and validity and thus might be suitable for assessment and counseling regarding medication adherence among adults with hypertension in a busy clinical setting in Korea.
