Abstract
Like patients with many chronic illnesses, ESRD patients experience psychological challenges with greater incidence of depression and reduced quality of life (QoL). A series of 139 transplant candidates' depression and QoL, and a subset of 82 candidates' medication adherence were monitored, revealing heterogenous patterns of depression and adherence and reduced QoL. Twenty-eight patients who received kidney transplants were re-evaluated 6 months post-transplant revealing mixed patterns. Mean depression and quantitated adherence decreased and QoL increased. Some patients improved whereas others declined in depression and adherence. Pre-transplant depression was negatively correlated with post-transplant adherence but positively correlated with post-transplant depression. Nevertheless, the ability to predict individuals' post-transplant adherence and depression, principal objectives of pre-transplant psychological evaluations, is limited. Consequently, it is important to provide periodic screening of ESRD patients for depression and adherence pre- and post-transplant as they reflect changing states, rather than static traits, with variable patterns across patients.

Wu JR, Moser DK. Health-Related Quality of Life Is a Mediator of the Relationship Between Medication Adherence and Cardiac Event-Free Survival in Patients with Heart Failure. J Card Fail 2021; 27:848-856. [PMID: 34364662 DOI: 10.1016/j.cardfail.2021.03.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 02/25/2021] [Accepted: 03/05/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Health-related quality of life (HRQOL) is an important patient-reported outcome that is related to medication adherence, hospitalization and death. The nature of the relationships among medication adherence, HRQOL, and hospitalization and death is unknown. We sought to determine the relationships among medication adherence, HRQOL, and cardiac event-free survival in patients with heart failure. METHODS AND RESULTS We enrolled 218 patients with heart failure. Patients' medication adherence was measured objectively using the Medication Event Monitoring System. HRQOL was assessed using the Minnesota Living with Heart Failure Questionnaire. Patients were followed for up to 3.5 years to collect hospitalization and mortality data. Mediation analysis was used to determine the nature of the relationships among the variables. Patients with better medication adherence had better HRQOL (P = .014). Medication adherence and HRQOL were associated with cardiac event-free survival (both P < .05). Patients with medication nonadherence were 1.86 times more likely to experience a cardiac event than those with better medication adherence (P = .038). Medication adherence was not associated with cardiac event-free survival after entering HRQOL in the model (P = .118), indicating mediation by HRQOL of the relationship between medication adherence and cardiac event-free survival. CONCLUSIONS HRQOL mediated the relationship between medication adherence and cardiac event-free survival. It is important to assess medication adherence and HRQOL regularly and develop interventions to improve medication adherence and HRQOL to decrease hospitalization and mortality in patients with heart failure.

Abstract
BACKGROUND Nonadherence diminishes the efficacy of direct oral anticoagulants (DOACs) in patients with nonvalvular atrial fibrillation (NVAF). This report presents the baseline survey results regarding medication adherence among NVAF patients who were treated with once-daily edoxaban or twice-daily apixaban from a randomized control trial of the effect of an educational intervention on DOAC adherence. METHODS We prospectively studied 301 NVAF patients who were treated with edoxaban (n = 175) or apixaban (n = 126) during the 12-week observation period. Adherence was measured with an electronic monitoring system and is expressed as the percentage of days with the correct doses in the measurement period (days). Adherence to DOAC therapy was defined based on the standard threshold (≥80%) or a strict threshold (≥90%). RESULTS Of the 301 patients, 33 had incomplete data or protocol deviations, leaving 268 patients (edoxaban 158 and apixaban 110) for the per-protocol baseline analysis. There was no difference in adherence (threshold ≥80%) between the groups (edoxaban 95% vs apixaban 91%, P = .2), but there was a lower proportion of patients with strict adherence (threshold ≥90%) among apixaban users than among edoxaban users (edoxaban 87% vs apixaban 76%, P = .02). Multivariate analysis showed a negative relationship between apixaban use and an adherence rate ≥90% (odds ratio 0.49, 95% confidence interval [CI]: 0.25-0.94). CONCLUSIONS Our study showed that the proportion of DOAC users with adherence (≥80%) did not differ between the groups, but the proportion of patients with strict adherence (≥90%) was lower among those using apixaban than among those using edoxaban.

Abstract
BACKGROUND Youth with bipolar disorder (BP) exhibit poor medication adherence, contributing to affective recurrence. Brief Motivational Interventions (BMIs) improve adherence among adolescents with chronic conditions. METHODS In an open pilot series, we developed a 3-session BMI for BP adolescents targeting medication adherence and conducted a pilot randomized trial comparing Standard Care (SC) versus SC+BMI. Participants include 43 adolescents with BP prescribed psychotropic medications. We assessed medication adherence objectively via bluetooth-enabled electronic pillbox (MedTracker). A blinded evaluator assessed mood symptoms at intake, 3- and 6-months. RESULTS The BMI was well-received. Average objective medication adherence increased with time in SC+BMI, but decreased in SC-Alone (p < 0.0001). Adolescents' baseline self-rated expectation of improvement with treatment moderated the effect of treatment on improvement in adherence over time (p = 0.003). Across groups, poor adherence predicted increased likelihood of depression and hypo/mania symptoms in the subsequent two weeks; medication adherence mediated the effect of the BMI on the likelihood of depressive symptoms (p = 0.007). LIMITATIONS Electronic pillbox use (across groups) may enhance adherence, resulting in overestimates compared with naturalistic conditions. This pilot randomized trial may have been underpowered to detect some group differences. CONCLUSIONS A BMI offers promise as a disseminable adjunctive intervention for improving medication adherence for adolescents with BP. Future studies with larger samples can establish efficacy.

Abstract
Objective To assess methotrexate (MTX) adherence using the Medication Event Monitoring System (MEMS) and characterize associations with adherence in patients with rheumatoid arthritis (RA). Methods Eligible patients participated in Forward, the National Databank for Rheumatic Diseases, and recently (12 months or sooner) initiated oral MTX. MEMS was used to compile MTX weekly dosing over 24 weeks. The Beliefs about Medicines Questionnaire (BMQ) was completed, and baseline demographics and disease characteristics obtained. MTX adherence (percentage of weeks dose taken correctly), implementation (percentage of weeks dose taken correctly from initiation until last dose), and persistence (duration from initiation to last dose) were calculated. Analyses measured associations between patient characteristics and adherence, modeled using logistic generalized estimating equations and censored Poisson regression, and persistence modeled using Cox regression. Results Overall, 60 of 119 eligible patients were included in the analysis. MTX adherence, implementation, and persistence were 75%, 80%, and 83%, respectively, at 24 weeks. Demographics and disease characteristics were generally similar between patients with 1 week or less and 2 weeks or more of missed MTX. Unemployment, less disability, higher Patient Global scores, and no prior disease‐modifying antirheumatic drug (DMARD) use were associated with correct dosing. No significant differences in adherence were observed between patients receiving concomitant MTX versus MTX monotherapy, and biologic DMARD‐experienced versus biologic DMARD‐naïve patients. Higher scores in BMQ Specific Necessity (indicating a greater belief in the necessity of the medication) was associated with a decreased likelihood of dosing at an interval shorter than prescribed (odds ratio 0.89). Conclusion Even in a participatory group over a short period, MTX adherence was suboptimal and associated with certain demographics, medication experience, and beliefs about medicines. This suggests a need for screening and alternative treatment opportunities in nonadherent MTX patients with RA.

Abstract
In adults living with HIV, pharmacy refill data are good predictors of virologic failure (VF). The utility of pharmacy refill data for predicting VF in adolescents has not been reported. We evaluated data from 291 adolescents on antiretroviral therapy. The main outcome measure was VF, defined as two consecutive HIV viral load measurements ≥ 400 copies/mL during 24-months of follow-up. Pharmacy refill non-adherence was defined as two consecutive refill adherence measurements < 95% during the same period. Fifty-three (18%) adolescents experienced VF. One hundred twenty-eight (44%) adolescents had refill non-adherence. Refill non-adherence had poor discriminative ability for indicating VF (receiver operating characteristic AUC = 0.60). Sensitivity and specificity for predicting VF was poor (60% (95% CI 46-74%) and 60% (95% CI 53-66%), respectively). The lack of a viable surrogate for VF in adolescents highlights the urgent need for more access to virologic testing and novel methods of monitoring adolescent treatment adherence.

Abstract
Nonadherence in children who use long-term medication is a serious problem and assessing adherence is an important step to provide solutions to this problem. Medication adherence can be measured by several methods, including (a) self-report questionnaires or structured interviews, (b) therapeutic drug monitoring (TDM), (c) electronic devices, and (d) pick-up/refill rates. The objective of this narrative review is to provide an overview of the literature about methods for the measurement of medication adherence in chronically ill children and adolescents. Therefore, we conducted a literature search by using multiple databases. Four methods of monitoring medication adherence are presented for the most described chronic diseases: asthma, HIV/AIDS, epilepsy, diabetes mellitus and ADHD. First, 10 commonly used self-report questionnaires and structured interviews are described, including the main characteristics, (dis)advantages and their validation studies. Second, the use of TDM in pediatric trials for medication adherence measurement is discussed. New sampling methods (e.g. dried blood spot) and sampling matrices (e.g. hair, saliva and urine) have shown their benefits for TDM in children. Third, electronic devices to measure medication adherence in children are presented, being developed for several drug administration routes. Fourth, the analyses, advantages and disadvantages of pharmacy data are discussed. The usage of this data requires specific calculations and interpretations to assess adherence. As presented in this review, every adherence method has specific (dis)advantages. When deciding which adherence method is applicable, validity and generalizability should be taken into account. Combining multiple methods seems to offer the best solution in the daily clinical practice.

Abstract
BACKGROUND Heart failure (HF) symptoms such as dyspnea are common and may precipitate hospitalization. Medication nonadherence is presumed to be associated with symptom exacerbations, yet how HF symptoms, medication adherence, and hospitalization/death are related remains unclear. OBJECTIVE The aim of this study was to explore the relationships among HF symptoms, medication adherence, and cardiac event-free survival in patients with HF. METHODS At baseline, patient demographics, clinical data, and HF symptoms were collected in 219 patients with HF. Medication adherence was monitored using the Medication Event Monitoring System. Patients were followed for up to 3.5 years to collect hospitalization and survival data. Logistic regression and survival analyses were used for the analyses. RESULTS Patients reporting dyspnea or ankle swelling were more likely to have poor medication adherence (P = .05). Poor medication adherence was associated with worse cardiac event-free survival (P = .006). In Cox regression, patients with HF symptoms had 2 times greater risk for a cardiac event than patients without HF symptoms (P = .042). Heart failure symptoms were not a significant predictor of cardiac event-free survival after entering medication adherence in the model (P = .091), indicating mediation. CONCLUSIONS Medication adherence was associated with fewer HF symptoms and lower rates of hospitalization and death. It is important to develop interventions to improve medication adherence that may reduce HF symptoms and high hospitalization and mortality in patients with HF.

Abstract
PURPOSE For postmenopausal women with hormone receptor-positive breast cancer, long-term use of aromatase inhibitors (AIs) significantly reduces the risk of cancer recurrence and improves survival. Still, many patients are nonadherent due to adverse side effects. We conducted a pilot randomized controlled trial to test the use of a web-based application (app) designed with and without weekly reminders for patients to report real-time symptoms and AI use outside of clinic visits with built-in alerts to patients' oncology providers. Our goal was to improve symptom burden and medication adherence. METHODS Forty-four women with early-stage breast cancer and a new AI prescription were randomized to either an App+Reminder (weekly reminders to use app) or an App (no reminders) group. Pre- and post-assessment data were collected from all participants. RESULTS Participants in the App+Reminder group had higher weekly app usage rate (74 vs. 38%, p < 0.05) during the intervention and reported higher AI adherence at 8 weeks (100 vs. 72%, p < 0.05). Symptom burden increase was higher for the App group compared to the App+Reminder group but did not reach statistical significance. CONCLUSIONS Weekly reminders to use a web-based app to report AI adherence and treatment-related symptoms demonstrated feasibility and improved short-term AI adherence, which may reduce symptom burden for women with breast cancer and a new AI prescription. IMPLICATIONS FOR CANCER SURVIVORS If short-term gains in adherence persist, this low-cost intervention could improve survival outcomes for women with breast cancer. A larger, long-term study should examine if AI adherence and symptom burden improvements persist for a 5-year treatment period.

Abstract
Pill counts with calculated adherence percentages are used in many settings to monitor adherence, but can be undermined by patients discarding pills to hide nonadherence. Pill counts suggesting that >100% of prescribed doses were taken can signal "pill dumping." We defined "overadherence" among a cohort of 300 HIV-infected adolescents as having greater than one-third of pill counts with >100% adherence during a year of follow-up. Apparent overadherence was more common in those with virologic failure than in those with suppressed viral loads (33% vs 13%, χ(2) P = 0.001). Pill count adherence repeatedly >100% may identify HIV-infected adolescents at increased risk of treatment failure.

Abstract
OBJECTIVE To identify self-care behaviors, instruments, techniques, parameters for the assessment of self-care behaviors in people with heart failure, compare these behaviors with the indicators of the Nursing Outcomes Classification outcome, Self Management: Cardiac Disease. METHOD Integrative literature review performed in Lilacs, Medline, CINAHL, and Cochrane, including publications from 2009 to 2015. One thousand six hundred ninety-one articles were retrieved from the search, of which 165 were selected for analysis. RESULTS Ten self-care behaviors and several different assessment instruments, techniques, and parameters were identified. The addition and removal of some indicators are proposed, based on this review. The data provide substrate for the development of conceptual and operational definitions of the indicators, making the outcome more applicable for use in clinical practice.

Abstract
OBJECTIVE E-diaries and accelerometers promise more objective, real-time measurements of health behavior. However, social-psychological theory suggests that using electronic behavioral monitoring may influence rather than just record physical activity (PA), especially when a device is novel. DESIGN Participants (n=146) were randomly assigned to either an accelerometer-only, e-diary-only, accelerometer+e-diary, or a no-technology control group for one week to assess how these technologies influenced PA, both perceived and actual, in young adults. METHOD Participants reported their PA, overall and number of discrete exercise sessions (DES) at baseline and follow-up; accelerometers provided daily step counts and e-diaries captured daily reports of PA for the active week of the study. RESULTS Average daily steps in the accelerometer-only and accelerometer+e-diary groups did not differ nor did daily reports of PA via e-diary compared to accelerometer+e-diary group, showing that neither technology affected actual PA. ANCOVAS tested group differences in perceived PA; The accelerometer-only group had increased perceived overall PA but not DES compared to no-technology control. CONCLUSIONS Accelerometers may increase perceived overall PA, but the tested technologies did not increase DES or actual PA, suggesting that they may be viable unbiased measures of PA.

Abstract
BACKGROUND To assess the occurrence of white coat adherence, defined as an increase in adherence to treatment regimens prior to a study appointment, in adolescents with type 1 diabetes (T1D) using insulin pumps and participating in a randomized adherence intervention trial. METHODS Blood glucose monitoring (BGM) readings, carbohydrate inputs, and insulin boluses delivered were downloaded from the insulin pumps of adolescents, aged 10-18 years, at 3 consecutive T1D study visits. Linear mixed models were used to analyze patterns of BGM, carbohydrate inputs, and insulin boluses delivered in patients who had 40 consecutive days of data stored in their insulin pumps prior to the study visit. RESULTS Stratified linear mixed models revealed that adolescents randomized to the Tailored Feedback Intervention group increased their blood glucose monitoring ( P < .01), carbohydrate inputs ( P < .0001), and insulin bolusing ( P < .0001) prior to study appointments. In contrast, white coat adherence did not occur in adolescents randomized to the Treatment as Usual group ( Ps > .42). CONCLUSIONS White coat adherence may occur in adolescents participating in clinical trials. Meter and insulin pump data downloads representing the 1- to 2-week period prior to a study visit are likely to overestimate actual adherence during the time frame between study visits.

Abstract
Abstract
Background: Medication nonadherence is common in elderly patients and is a major cause of morbidity. However, it is not well-described in the literature and to our knowledge has never been studied in Thais.
Objective: To investigate the extent, causes, and contributing factors of medication nonadherence in older patients in a geriatric clinic.
Material and Methods: We conducted a cross-sectional study at Siriraj Hospital, a university teaching hospital in Bangkok. We assessed baseline demographic data, comorbid diseases, Thai Mental State Examination (TMSE), functional status (basic and basic activities of daily living), type and number of medications used, and medication adherence.
Results: There were 153 participants in this study. Medication nonadherence, in the administration of prescribed drugs only, was found in 34% of the participants. Nonadherence to administration of prescribed drugs and to the advice regarding over-the-counter drugs was 42.5%. Nonadherence to the administration of prescribed drugs and to the advice regarding over-the-counter drugs, and herbal and dietary supplements was 54.9%. Three most common causes of medication nonadherence were misunderstanding or lack of the knowledge (25.6%), the development of adverse drug events (18.9%), and because of a suggestion by a friend or family member (16.2%).
Conclusion: Medication nonadherence is common in elderly Thais attending geriatric clinics. We recommend clinicians be aware of this problem and develop a system to improve medication adherence. The clarification of reasons for prescribing is crucial. We recommend emphasis on educating patients, family members, and the public about the risk of nonadherence and of using nonprescribed medications.

Abstract
BACKGROUND The purpose was to assess the occurrence of white coat adherence, defined as an increase in adherence to treatment regimens prior to a clinic appointment, in children and adolescents with type 1 diabetes (T1D) who use insulin pumps. METHODS Blood glucose monitoring (BGM) data, carbohydrate inputs, and insulin boluses delivered were downloaded from the insulin pumps of children and adolescents, aged 7-19 years with T1D, at 2 consecutive routine diabetes clinic visits. Linear mixed models were used to analyze patterns of BGM, carbohydrate inputs, and insulin boluses delivered in patients who had ≥28 days of data stored in their insulin pumps. RESULTS In general, younger children engaged in more frequent BGM, carbohydrate inputs, and insulin boluses delivered than older children and adolescents. White coat adherence occurred with frequency of BGM, carbohydrate inputs, and insulin boluses delivered, but only in younger children. CONCLUSIONS Diabetes care providers need to be aware that white coat adherence may occur, particularly in young children. Providers routinely download meter and insulin pump data for the 1- to 2-week period before the clinic visit. For patients exhibiting white coat adherence, their data will overestimate the patient's actual adherence.

Abstract
Implantable medical devices have been implemented to provide treatment and to assess in vivo physiological information in humans as well as animal models for medical diagnosis and prognosis, therapeutic applications and biological science studies. The advances of micro/nanotechnology dovetailed with novel biomaterials have further enhanced biocompatibility, sensitivity, longevity and reliability in newly-emerged low-cost and compact devices. Close-loop systems with both sensing and treatment functions have also been developed to provide point-of-care and personalized medicine. Nevertheless, one of the remaining challenges is whether power can be supplied sufficiently and continuously for the operation of the entire system. This issue is becoming more and more critical to the increasing need of power for wireless communication in implanted devices towards the future healthcare infrastructure, namely mobile health (m-Health). In this review paper, methodologies to transfer and harvest energy in implantable medical devices are introduced and discussed to highlight the uses and significances of various potential power sources.

Abstract
Medication nonadherence is a vexing problem in health care necessitating patients and health professionals' efforts to prevent, minimize, or reverse it. Research participants' inconsistent medication taking obscures treatment efficacy and adds costs to biomedical research. Electronic monitoring devices (EMDs), like the Medication Event Monitoring System (MEMS), have grown in sophistication, providing precise, timely insights into individuals' medication-taking patterns across clinical populations. This article reports on the desirability and feasibility study of using a wireless EMD in clinical research to promote adherence to clinical regimens and research protocols. Nonadherence in transplant patients has been linked to late acute rejection and graft loss. High levels of adherence (97.7 %) were documented for six renal transplant recipients for a mean of 6 months (M = 196.1 ± 71.2 days) who indicated acceptance of the technology. MEMS data confirmed the feasibility of using wireless EMDs to monitor medication use. Monitoring provides greater assurance that research studies reflect the biological impact of medications and provide a basis for targeting adherence enhancement efforts within research investigations.

Abstract
BACKGROUND Medication nonadherence and depressive symptoms predict hospitalization and death in patients with heart failure (HF). Depressed patients have lower medication adherence than nondepressed patients. However, the predictive power of the combination of medication adherence and depressive symptoms for hospitalization and death has not been investigated in patients with HF. OBJECTIVE The aim of this study was to explore the combined influence of medication adherence and depressive symptoms for prediction of cardiac event-free survival in patients with HF. METHODS AND RESULTS We monitored medication adherence in 216 HF patients who completed the Patient Health Questionnaire-9 (PHQ-9) at baseline. Medication adherence was measured objectively with the use of the Medication Event Monitoring System (MEMS). Patients were followed for up to 3.5 years to collect data on cardiac events. Survival analyses were used to compare cardiac event-free survival among groups. The risk of experiencing a cardiac event for patients with medication nonadherence and depressive symptoms was 5 times higher than those who were medication adherent without depressive symptoms. The risk of experiencing a cardiac event for patients with only 1 risk factor was 1.2-1.3 times that of those with neither risk factor. CONCLUSIONS Medication nonadherence and depressive symptoms had a negative synergistic effect on cardiac event-free survival in patients with HF.

Abstract
The aim of this study was to describe an integrated informatics approach to aggregating and displaying clinically relevant data that can identify problems with medication adherence and facilitate patient-provider communication about strategies to improve medication use. We developed a clinical dashboard within an electronic health record (EHR) system that uses data from three sources: the medical record, pharmacy claims, and a personal health record. The data are integrated to inform clinician-patient discussions about medication adherence. Whereas prior research on assessing patterns of medication adherence focused on a single approach using the EHR, pharmacy data, or patient-entered data, we present an approach that integrates multiple electronic data sources increasingly found in practice. Medication adherence is a complex challenge that requires patient and provider team input, necessitating an integrated approach using advanced EHR, clinical decision support, and patient-controlled technologies. Future research should focus on integrated strategies to provide patients and providers with the right combination of informatics tools to help them adequately address the challenge of adherence to complex medication therapies.

Abstract
OBJECTIVE To develop and evaluate a multiprofessional modular medication management to assure adherence to capecitabine. METHODS The study was conducted as a prospective, multicentred observational cohort study. All participants received pharmaceutical care consisting of oral and written information. Daily adherence was defined as percentage of days with correctly administered capecitabine doses and assessed using medication event monitoring. According to their daily adherence during the first cycle, patients were identified as initially non-adherent (<90% adherence) or adherent (≥90% adherence). Initially non-adherent patients received additional adherence support. RESULTS Seventy-three patients with various tumour entities were enrolled, 58 were initially adherent and 15 non-adherent. Median daily adherence of initially non-adherent patients increased from 85.7% to 97.6% during the observation period of six cycles. Throughout all cycles, median daily adherence of initially adherent patients was 100.0%. Daily adherence was not associated with sociodemographic and disease-related factors. No patient was non-persistent. CONCLUSIONS An early adherence screening effectively distinguishes between patients adhering and non-adhering to capecitabine. The provision of specific adherence support is associated with enhanced adherence of initially non-adherent patients, whereas initially adherent patients remain adherent for at least six cycles without specific support. Our needs-based approach helps to use available resources for adherence management efficiently.

Abstract
OBJECTIVES To examine the issue of accurate adherence assessment and illustrate methodologies for correcting parent-reported medication adherence. METHODS 40 children with inflammatory bowel disease provided medication adherence data using electronic monitoring. Parents provided subjective reports of medication adherence. Receiver operating characteristic analyses were used to examine the detection of non-adherence at several adherence cut-points. 2 methods for empirically deriving a correction factor for subjectively reported adherence were applied. RESULTS Although parent-report and EM adherence were significantly correlated, parent-reported adherence was significantly higher than EM adherence. A 90% cut-point provided the highest sensitivity and specificity. Both correction factors reliably adjusted parent-reported adherence based on EM adherence. CONCLUSIONS Application of an empirically derived correction factor for parent-reported adherence using methodologies, such as those illustrated in the current study, could yield more accurate adherence assessment. Obtaining more accurate adherence assessments based on parent-report will have implications for self-management interventions, clinician prescribing behavior, and medication safety.

Abstract
OBJECTIVE To describe a mixed-methods approach to develop and test a basic behavioral science-informed intervention to motivate behavior change in 3 high-risk clinical populations. Our theoretically derived intervention comprised a combination of positive affect and self-affirmation (PA/SA), which we applied to 3 clinical chronic disease populations. METHOD We employed a sequential mixed methods model (EVOLVE) to design and test the PA/SA intervention in order to increase physical activity in people with coronary artery disease (post-percutaneous coronary intervention [PCI]) or asthma (ASM) and to improve medication adherence in African Americans with hypertension (HTN). In an initial qualitative phase, we explored participant values and beliefs. We next pilot tested and refined the intervention and then conducted 3 randomized controlled trials with parallel study design. Participants were randomized to combined PA/SA versus an informational control and were followed bimonthly for 12 months, assessing for health behaviors and interval medical events. RESULTS Over 4.5 years, we enrolled 1,056 participants. Changes were sequentially made to the intervention during the qualitative and pilot phases. The 3 randomized controlled trials enrolled 242 participants who had undergone PCI, 258 with ASM, and 256 with HTN (n = 756). Overall, 45.1% of PA/SA participants versus 33.6% of informational control participants achieved successful behavior change (p = .001). In multivariate analysis, PA/SA intervention remained a significant predictor of achieving behavior change (p < .002, odds ratio = 1.66), 95% CI [1.22, 2.27], controlling for baseline negative affect, comorbidity, gender, race/ethnicity, medical events, smoking, and age. CONCLUSIONS The EVOLVE method is a means by which basic behavioral science research can be translated into efficacious interventions for chronic disease populations.

Abstract
BACKGROUND Clinicians have difficulty in identifying patients that are unlikely to adhere to hypertension self-management. Identifying non-adherence is essential to addressing suboptimal blood pressure control and high costs. OBJECTIVES 1) To identify risk factors associated with non-adherence to three key self-management behaviors in patients with hypertension: proper medication use, diet, and exercise; 2) To evaluate the extent to which an instrument designed to identify the number of risk factors present for non-adherence to each of the three hypertension self-management behaviors would be associated with self-management non-adherence and blood pressure. DESIGN Cross-sectional analysis of randomized trial data. PATIENTS Six hundred and thirty-six primary care patients with hypertension. MEASUREMENTS 1) Demographic, socioeconomic, psychosocial, and health belief-related factors; 2) measures of self-reported adherence to recommended medication use, diet recommendations, and exercise recommendations, all collected at baseline assessment; 3) systolic blood pressure (SBP) and diastolic blood pressure (DBP). RESULTS We identified patient factors associated with measures of non-adherence to medications, diet, and exercise in hypertension. We then combined risk factors associated with ≥1 adherence measure into an instrument that generated three composite variables (medication, diet, and exercise composites), reflecting the number of risk factors present for non-adherence to the corresponding self-management behavior. These composite variables identified subgroups with higher likelihood of medication non-adherence, difficulty following diet recommendations, and difficulty following exercise recommendations. Composite variable levels representing the highest number of self-management non-adherence risk factors were associated with higher SBP and DBP. CONCLUSIONS We identified factors associated with measures of non-adherence to recommended medication use, diet, and exercise in hypertension. We then developed an instrument that was associated with non-adherence to these self-management behaviors, as well as with blood pressure. With further study, this instrument has potential to improve identification of non-adherent patients with hypertension.

Abstract
This paper presents case examples that document the preliminary clinical utility of using electronic monitoring (EM) feedback to tailor empirically validated adherence-promoting interventions, delivered in standard clinical practice. Challenges of utilizing EM in standard clinical practice as well as future directions are also discussed. Two adolescents referred for behavioral adherence promotion intervention are described. Each youth was provided a MEMS® bottle and one oral medication was chosen jointly by the therapist, family, and medical provider for adherence monitoring. Graphical MEMS® feedback was provided to families during intervention visits and subsequently used to tailor adherence interventions to target each family's unique needs. EM feedback was a feasible and clinically rich supplement to adherence-promoting interventions. EM facilitated identification of adherence barriers and successes, and open and non-adversarial discussions regarding adherence between patients, families, and clinicians, and provided real-time representations of patients' medication administration. These case presentations suggest that EM feedback can be a clinically useful tool when used as a supplement to an empirically supported intervention delivered in standard psychological practice aimed at adherence promotion among chronically ill youth.

Abstract
BACKGROUND Rates of medication adherence are low among hypertensive blacks despite numerous interventions to increase their adherence. PURPOSE The aim of the study was to conduct a systematic review of the literature to understand the factors associated with medication adherence in hypertensive blacks. METHODS A systematic computer search of qualitative and quantitative studies that examined factors associated with medication adherence in hypertensive blacks from 1966 to 2010 was performed. Studies were excluded if medication adherence was not either the primary or secondary outcome variable. RESULTS Studies (n = 18) were cross-sectional or qualitative, measured adherence via self-report, and conducted in low-income blacks. Factors that were associated with medication adherence were self-efficacy, depression, patient-provider communication, and healthcare system related. CONCLUSIONS Findings from existing studies should be interpreted with caution because of their methodological limitations. Longitudinal studies with heterogeneous samples of hypertensive blacks are imperative so that targeted interventions can be developed for this vulnerable population. CLINICAL IMPLICATIONS Even though there are methodological limitations associated with existing studies, clinicians may want to consider some of the factors that were associated with medication adherence in this systematic review as they provide care for hypertensive blacks. Given that self-efficacy and patient-provider communication are modifiable factors, they can be the focus of interventions to increase medication adherence. Finally, clinicians may want to screen their hypertensive patients for depression and treat, if necessary.

Abstract
OBJECTIVES Medication adherence and perceived social support (PSS) are independent predictors of mortality in patients with heart failure (HF). However, the predictive power of the combination of medication adherence and PSS for hospitalization and death has not been investigated in patients with HF. The purpose of the study was to explore the combined influence of medication adherence and PSS for prediction of cardiac event-free survival in patients with HF. METHOD A total of 218 HF patients monitored medication adherence for 1-3 months and completed the Multidimensional Perceived Social Support Scale (MPSSS) at baseline. Medication adherence was measured using a valid and objective measure, the Medication Event Monitoring System (MEMS). Patients were followed for up to 3.5 years to collect data about cardiac event-free survival (i.e., cardiac emergency department visits, hospitalizations, and death). To test the association of the combination of medication adherence and PSS with outcomes, the interaction term of medication adherence and PSS was first entered in a Cox regression to predict outcomes. Second, patients were grouped using an evidence-based cutpoint of 88% for medication adherence from the MEMS data and a median score 71 of the MPSSS. Kaplan-Meier and Cox proportional hazards models were used to compare cardiac event-free survival among groups. RESULT Medication adherence and PSS were independent predictors of cardiac event-free survival (p = .006 and .021, respectively). Patients with medication nonadherence and lower PSS had a 3.5 times higher risk of cardiac events than those who were adherent and had higher PSS. CONCLUSION Medication adherence mediated the relationship between PSS and cardiac event-free survival in this sample. Moreover, medication adherence and social support independently, and in combination, predicted cardiac event-free survival in patients with HF. Interventions to improve clinical outcomes should address medication adherence and social support.

Abstract
AbstractElectronic caps (most often Microelectronic Monitoring Systems; MEMS) that record date and time of bottle opening have been widely used to describe medication adherence. This paper expands upon descriptions of adherence-focused therapy built around review of MEMS data with the patient, adding the application of Motivational Enhancement Therapy (MET) principles. MEMS Feedback Therapy involves (a) motivational interviewing to complement the skill-building aspects of MEMS review; (b) detailed MEMS review with discussion of patterns of missed doses, and thoughts, feelings and habits accompanying missed doses; and (c) medication-taking routines to suggest after MET and MEMS review have prepared the patient to follow advice.

Abstract
BACKGROUND Poor adherence explains poor blood pressure (BP) control; however African Americans suffer worse hypertension-related outcomes. METHODS This randomized controlled trial evaluated whether a patient education intervention enhanced with positive-affect induction and self-affirmation (PA) was more effective than patient education (PE) alone in improving medication adherence and BP reduction among 256 hypertensive African Americans followed up in 2 primary care practices. Patients in both groups received a culturally tailored hypertension self-management workbook, a behavioral contract, and bimonthly telephone calls designed to help them overcome barriers to medication adherence. Also, patients in the PA group received small gifts and bimonthly telephone calls to help them incorporate positive thoughts into their daily routine and foster self-affirmation. The main outcome measures were medication adherence (assessed with electronic pill monitors) and within-patient change in BP from baseline to 12 months. RESULTS The baseline characteristics were similar in both groups: the mean BP was 137/82 mm Hg; 36% of the patients had diabetes; 11% had stroke; and 3% had chronic kidney disease. Based on the intention-to-treat principle, medication adherence at 12 months was higher in the PA group than in the PE group (42% vs 36%, respectively; P =.049). The within-group reduction in systolic BP (2.14 mm Hg vs 2.18 mm Hg; P = .98) and diastolic BP (-1.59 mm Hg vs -0.78 mm Hg; P = .45) for the PA group and PE group, respectively, was not significant. CONCLUSIONS A PE intervention enhanced with PA led to significantly higher medication adherence compared with PE alone in hypertensive African Americans. Future studies should assess the cost-effectiveness of integrating such interventions into primary care. Trial Registration clinicaltrials.gov Identifier: NCT00227175.

Abstract
BACKGROUND Medication nonadherence contributes to hospitalization and mortality, yet there have been few interventions tested that improve adherence and reduce hospitalization and mortality in heart failure (HF). Our objective was to determine whether an education intervention improved medication adherence and cardiac event-free survival. METHODS AND RESULTS A randomized controlled trial was conducted on 82 HF patients. The intervention was based on the theory of planned behavior (TPB) and included feedback of medication-taking behavior using the Medication Event Monitoring System (MEMS). Patients were assigned to one of three groups: 1) theory-based education plus MEMS feedback; 2) theory-based education only; or 3) usual care (control). Cardiac events were collected for 9 months. Patients in both intervention groups were more adherent over follow-up compared with the control group. In Cox regression, patients in either intervention group had a longer event-free survival compared with those in the control group before and after controlling age, marital status, financial status, ejection fraction, New York Heart Association functional class, angiotensin-converting enzyme inhibitor use, and presence or absence of a significant other during the intervention (P < .05). CONCLUSIONS Use of an intervention based on the TPB improves medication adherence and outcomes in patients with HF and therefore offers promise as a clinically applicable intervention to help patients with HF to adhere to their prescribed regimen.

Abstract
OBJECTIVE To assess the occurrence of white coat adherence in families with children who have type 1 diabetes. RESEARCH DESIGN AND METHODS Blood glucose data were downloaded from meters of 72 children, aged 2-11 years, with type 1 diabetes at four consecutive clinic visits. Generalized estimating equations were used to analyze patterns of blood glucose monitoring (BGM) during the 28 days before each clinic visit. RESULTS More frequent BGM was associated with better glycemic control. Evidence of a white coat adherence effect, with BGM frequency increasing before a clinic visit, was found only among children with low A1C levels. CONCLUSIONS Highly motivated families who frequently monitor their child's blood glucose increased the frequency of BGM before the child's clinic visit. The additional monitoring may benefit the child by providing the physician with a wealth of blood glucose information to guide recommendations.

Abstract
BACKGROUND Although nonadherence is well documented and strategies for adherence have been shown to be critical to overcoming barriers and improving overall adherence rates, it is unknown how family strategy use is related to adherence in the pediatric renal transplant population. OBJECTIVES The aims of this study were to assess (a) the strategies used by adolescents with kidney transplants and their caregivers to adhere to the posttransplant oral medication regimen and (b) the relationship of these strategies to objective adherence rates. METHODS Semistructured interviews to assess self-management were administered to 17 adolescents (14-18 years) and 17 caregivers. Adherence to oral immunosuppressant medication, measured via electronic monitors, was determined also for a subset of 13 dyads. RESULTS Common strategies endorsed by families included the following: making it part of the routine (88.2%), verbal reminders by caregiver (82.4%), caregiver verifying medication was taken (76.5%), placing medication in a convenient location (76.5%), and using a pillbox (70.6%). A greater number of family-endorsed strategies were correlated with higher levels of adherence. Of those strategies spontaneously endorsed, only caregiver reminders to take medication and caregiver verification that medications were taken were related significantly to higher adherence rates. DISCUSSION The findings highlight the importance of identification and use of specific strategies to improve adherence rates of pediatric renal transplant recipients and emphasize the need for continued caregiver involvement in the promotion of adherence to the treatment regimen.

Abstract
Suboptimal adherence with preventive medication is common and often unrecognised as a cause of poor asthma control. A number of risk factors for nonadherence have emerged from well-conducted studies. Unfortunately, patient report a physician's estimation of adherence and knowledge of these risk factors may not assist in determining whether non-adherence is a significant factor. Electronic monitoring devices are likely to be more frequently used to remind patients to take medication, as a strategy to motivate patients to maintain adherence, and a tool to evaluate adherence in subjects with poor disease control. The aim of this paper is to review non-adherence with preventive medication in childhood asthma, its impact on asthma control, methods of evaluating non-adherence, risk factors for suboptimal adherence, and strategies to enhance adherence.

Abstract
In the development of technology for people with mild dementia it is essential to achieve a combination of the features which provide both support and monitoring along with the ability to offer a level of personalization. Reminding support by means of personalized video reminders portraying a relative or friend combined with sensors to assess whether the requested task was performed lends itself as an ideal combination to achieve this aim. This study assesses the potential of using low cost, off the shelf sensors combined with a mobile phone-based video reminding system to assess compliance with task completion. A validation study has been conducted in a lab-based environment with 10 healthy young participants. The work presented discusses the implementation of the approach adopted, data analysis of the results attained along with outlining future developments of this approach.

Abstract
PURPOSE Study aims were (1) to document and examine associations between parent-report and electronic monitoring (EM) of pediatric antiepileptic drug (AED) adherence, (2) to determine the sensitivity and specificity of parent-reported adherence, and (3) to develop a correction factor for parent-reported adherence. METHODS Participants included 111 consecutive children with new-onset epilepsy (M(age) = 7.2 ± 2.0; 61.3% male; 75.8% Caucasian) and their primary caregivers. AED adherence was electronically monitored for 3 months prior to the 4-month clinic follow-up visit. Parent-reported adherence captured adherence 1-week prior to the clinic visit. For specificity/sensitivity analyses of parent-reported adherence, cut points of 50%, 80%, and 90% were used with electronically monitored adherence calculated 1-week prior to the clinic visit as the reference criterion. KEY FINDINGS Electronically monitored adherence (80.3%) was significantly lower than parent-reported adherence (96.5%; p < 0.0001) 1-week prior to the clinic visit, but both were significantly correlated (rho = 0.46, p < 0.001). The 90% parent-reported adherence cut point demonstrated the most sensitivity and specificity to electronically monitored adherence; however, specificity was still only 28%. A correction factor of 0.83 was identified as a reliable adjustment for parent-reported adherence when compared to electronically monitored adherence. SIGNIFICANCE Although EM is the gold standard of adherence measurement for pediatric epilepsy, it is often not clinically feasible to integrate it into routine clinical care. Therefore, use of a correction factor for interpreting parent-reported adherence holds promise as a reliable clinical tool. With reliable adherence measurement, clinicians can provide adherence interventions with the hope of optimizing health outcomes for children with epilepsy.

Abstract
BACKGROUND Non-adherence with immunosuppressive medications can result in allograft rejection and eventually allograft loss. METHODS In a racially diverse population, we utilized microelectronic cap monitors to determine the association of adherence with a single immunosuppressive medication and kidney allograft outcomes post-transplantation. This prospective cohort study enrolled 243 patients from eight transplant centers to provide adherence and kidney allograft outcomes data. To determine the association of adherence with change in estimated glomerular filtration rate (eGFR), we fit mixed effects models with the outcome being change in eGFR over time. We also fit Cox proportional hazards models to determine the association of adherence with time to persistent 25% and 50% decline in eGFR. RESULTS The distribution of adherence post-transplant was as follows: 164 (68%), 49 (20%), and 30 (12%) had >85-100%, 50-85%, and <50% adherence, respectively. Seventy-nine (33%) and 36 (15%) of the subjects experienced a persistent 25% decline in eGFR or allograft loss and 50% decline in eGFR or allograft loss during follow-up. Adherence was not associated with acute rejection or 25% decline or 50% decline in eGFR. In the adjusted and unadjusted model, adherence and black race were not associated with change in eGFR over time. CONCLUSIONS Non-adherence with a single immunosuppressive medication was not associated with kidney allograft outcomes.

Abstract
Background Compliance represents a major determinant for the effectiveness of pharmacotherapy. Compliance reports summarising electronically compiled compliance data qualify healthcare needs and can be utilised as part of a compliance enhancing intervention. Nevertheless, evidence-based information on a sufficient level of compliance is scarce complicating the interpretation of compliance reports. The purpose of our pilot study was to determine the compliance of ambulatory Alzheimer patients to antidementia drugs under routine therapeutic use using electronic monitoring. In addition, the forgiveness of donepezil (i.e. its ability to sustain adequate pharmacological response despite suboptimal compliance) was characterised and evidence-based guidance for the interpretation of compliance reports was intended to be developed. Methods We determined the compliance of four different antidementia drugs by electronic monitoring in 31 patients over six months. All patients were recruited from the gerontopsychiatric clinic of a university hospital as part of a pilot study. The so called medication event monitoring system (MEMS) was employed, consisting of a vial with a microprocessor in the lid which records the time (date, hour, minute) of every opening. Daily compliance served as primary outcome measure, defined as percentage of days with correctly administered doses of medication. In addition, pharmacokinetics and pharmacodynamics of donepezil were simulated to systematically assess therapeutic undersupply also incorporating study compliance patterns. Statistical analyses were performed with SPSS and Microsoft Excel. Results Median daily compliance was 94% (range 48%-99%). Ten patients (32%) were non-compliant at least for one month. One-sixth of patients taking donepezil displayed periods of therapeutic undersupply. For 10 mg and 5 mg donepezil once-daily dosing, the estimated forgiveness of donepezil was 80% and 90% daily compliance or two and one dosage omissions at steady state, respectively. Based on the simulation findings we developed rules for the evidence-based interpretation of donepezil compliance reports. Conclusions Compliance in ambulatory Alzheimer patients was for the first time assessed under routine conditions using electronic monitoring: On average compliance was relatively high but variable between patients. The approach of pharmacokinetic/pharmacodynamic in silico simulations was suitable to characterise the forgiveness of donepezil suggesting evidence-based recommendations for the interpretation of compliance reports.

Abstract
OBJECTIVES To assess the influence of depressive symptoms on adherence with heart failure medications and to determine whether the effect of a pharmacy-based intervention to improve heart failure medication adherence is modified by depressive symptoms. DESIGN Secondary analysis of data from a randomized controlled trial. SETTING University-affiliated ambulatory care practice. PATIENTS Patients 50 years or older with congestive heart failure randomly assigned to usual care (n = 192) or intervention (n = 122). INTERVENTION Pharmacist-provided intervention to improve heart failure medication adherence. MAIN OUTCOME MEASURES Medication adherence was measured via patient self-report and using electronic prescription lids; depressive symptoms were measured using the Geriatric Depression Scale. General linear models examined the main effect of depressive symptoms on medication adherence and whether depressive symptoms modified the effectiveness of the intervention. RESULTS At baseline, 37% (n = 117) of participants screened positive for depression. In the usual care group, mean adjusted self-reported adherence was 75% for depressed participants and 81% for nondepressed participants (P = 0.04); mean adjusted adherence measured electronically was 71% for depressed participants and 69% for nondepressed participants (P = 0.65). INTERVENTION effectiveness did not differ for depressed compared with nondepressed participants. CONCLUSION The effectiveness of a pharmacy-based intervention to improve adherence does not appear to be influenced by depression. However, the method used to measure adherence (electronically measured versus self-reported) influences the interpretation of the relationship between depression and heart failure medication adherence.

Abstract
This study evaluated older renal transplant recipients' perceptions of electronic medication monitoring and the influence of these perceptions on medication adherence. A sample of 73 older adult renal transplant recipients who used the Medication Event Monitoring System (MEMS(®)) TrackCaps for 12 months provided their perceptions of device use. Participants perceived that the MEMS had a neutral effect on their medication-taking routine (65%), believed the MEMS was practical (56%), and could not describe any instances in which using the MEMS was difficult (56%). No significant difference in medication adherence was found between those who perceived the MEMS's influence negatively/neutrally and those who perceived the MEMS positively (p = 0.22). Medication adherence data from older adult renal transplant recipients can be used regardless of their perceptions of the MEMS's influence on their medication taking without biasing medication adherence data.

Abstract
OBJECTIVES Adherence to medical regimens for children and adolescents with chronic conditions is generally below 50% and is considered the single, greatest cause of treatment failure. As the prevalence of chronic illnesses in pediatric populations increases and awareness of the negative consequences of poor adherence become clearer, the need for reliable and valid measures of adherence has grown. METHODS This review evaluated empirical evidence for 18 measures utilizing three assessment methods: (a) self-report or structured interviews, (b) daily diary methods, and (c) electronic monitors. RESULTS Ten measures met the "well-established" evidence-based (EBA) criteria. CONCLUSIONS Several recommendations for improving adherence assessment were made. In particular, consideration should be given to the use of innovative technologies that provide a window into the "real time" behaviors of patients and families. Providing written treatment plans, identifying barriers to good adherence, and examining racial and ethnic differences in attitudes, beliefs and behaviors affecting adherence were strongly recommended.

Abstract
BACKGROUND Poor medication adherence is a significant problem in hypertensive African Americans. Although motivational interviewing (MINT) is effective for adoption and maintenance of health behaviors in patients with chronic diseases, its effect on medication adherence remains untested in this population. METHODS This randomized controlled trial tested the effect of a practice-based MINT counseling vs. usual care (UC) on medication adherence and blood pressure (BP) in 190 hypertensive African Americans (88% women; mean age 54 years). Patients were recruited from two community-based primary care practices in New York City. The primary outcome was adherence measured by electronic pill monitors; the secondary outcome was within-patient change in office BP from baseline to 12 months. RESULTS Baseline adherence was similar in both groups (56.2 and 56.6% for MINT and UC, respectively, P = 0.94). Based on intent-to-treat analysis using mixed-effects regression, a significant time x group interaction with model-predicted posttreatment adherence rates of 43 and 57% were found in the UC and MINT groups, respectively (P = 0.027), with a between-group difference of 14% (95% confidence interval, -0.2 to -27%). The between-group difference in systolic and diastolic BP was -6.1 mm Hg (P = 0.065) and -1.4 mm Hg (P = 0.465), respectively, in favor of the MINT group. CONCLUSIONS A practice-based MINT counseling led to steady maintenance of medication adherence over time, compared to significant decline in adherence for UC patients. This effect was associated with a modest, nonsignificant trend toward a net reduction in systolic BP in favor of the MINT group.
