RESUMO
OBJECTIVES: To identify the top priority areas for research to optimize pharmacotherapy in older adults with cardiovascular disease (CVD). DESIGN: Consensus meeting. SETTING: Multidisciplinary workshop supported by the National Institute on Aging, the American College of Cardiology, and the American Geriatrics Society, February 6-7, 2017. PARTICIPANTS: Leaders in the Cardiology and Geriatrics communities, (officers in professional societies, journal editors, clinical trialists, Division chiefs), representatives from the NIA; National Heart, Lung, and Blood Institute; Food and Drug Administration; Centers for Medicare and Medicaid Services, Alliance for Academic Internal Medicine, Patient-Centered Outcomes Research Institute, Agency for Healthcare Research and Quality, pharmaceutical industry, and trainees and early career faculty with interests in geriatric cardiology. MEASUREMENTS: Summary of workshop proceedings and recommendations. RESULTS: To better align older adults' healthcare preferences with their care, research is needed to improve skills in patient engagement and communication. Similarly, to coordinate and meet the needs of older adults with multiple comorbidities encountering multiple healthcare providers and systems, systems and disciplines must be integrated. The lack of data from efficacy trials of CVD medications relevant to the majority of older adults creates uncertainty in determining the risks and benefits of many CVD therapies; thus, developing evidence-based guidelines for older adults with CVD is a top research priority. Polypharmacy and medication nonadherence lead to poor outcomes in older people, making research on appropriate prescribing and deprescribing to reduce polypharmacy and methods to improve adherence to beneficial therapies a priority. CONCLUSION: The needs and circumstances of older adults with CVD differ from those that the current medical system has been designed to meet. Optimizing pharmacotherapy in older adults will require new data from traditional and pragmatic research to determine optimal CVD therapy, reduce polypharmacy, increase adherence, and meet person-centered goals. Better integration of the multiple systems and disciplines involved in the care of older adults will be essential to implement and disseminate best practices. J Am Geriatr Soc 67:371-380, 2019.

Heart failure is a chronic disease requiring careful attention to self-care. Patients must follow instructions for diet and medication use to prevent or delay a decline in functional status, quality of life, and expensive care. However, there is considerable heterogeneity in heart failure patients' knowledge of important care routines, their cognition, and their health literacy, which predict the ability to implement self-care. Our interdisciplinary team of cognitive scientists with health literacy expertise, pharmacists, and physicians spent 18 years designing and testing protocols and materials to assist ambulatory heart failure patients with their care. Our approach is theory- as well as problem-driven, guided by our process-knowledge model of health literacy as it relates to self-care among older adult outpatients with either heart failure or hypertension. We used what we had learned from this model to develop a pharmacy-based protocol and tailored patient instruction materials that were the central component of a randomized clinical trial. Our results showed improved adherence to cardiovascular medications, improved health outcomes and patient satisfaction, and direct cost reductions. These results demonstrate the value of our interdisciplinary efforts for developing strategies to improve instruction and communication with attention to health literacy, which are core components of pharmacy and other ambulatory healthcare services. We believe attention to health literacy with medication use will result in improved health outcomes for older adult patients with heart failure and other complex chronic diseases.

The term comparative effectiveness research (CER) took center stage with passage of the American Recovery and Reinvestment Act (2009). The companion US$1.1 billion in funding prompted the launch of initiatives to train the scientific workforce capable of conducting and using CER. Passage of the Patient Protection and Affordable Care Act (2010) focused these initiatives on patients, coining the term 'patient-centered outcomes research' (PCOR). Educational and training initiatives were soon launched. This report describes the initiative of the Pharmaceutical Research and Manufacturers Association of America (PhRMA) Foundation. Through provision of grant funding to six academic Centers of Excellence, to spearheading and sponsoring three national conferences, the PhRMA Foundation has made significant contributions to creation of the scientific workforce that conducts and uses CER/PCOR.

Cardiovascular disease increases incrementally with age and elderly patients concomitantly sustain multimorbidities, with resultant prescription of multiple medications. Despite conforming with disease-specific cardiovascular clinical practice guidelines, this polypharmacy predisposes many elderly individuals with cardiovascular disease to adverse drug events and non-adherence. Patient-centered care requires that the clinician explore with each patient his or her goals of care and that this shared decision-making constitutes the basis for optimization of medication management. This approach to aligning therapies with patient preferences is likely to promote patient satisfaction, to limit morbidity, and to favorably affect healthcare costs.

STUDY OBJECTIVE: To assess the effect of health literacy on drug adherence in the context of a pharmacist-based intervention for patients with heart failure. DESIGN: Post hoc analysis of a randomized controlled trial. SETTING: Inner-city ambulatory care practice affiliated with an academic medical center. PATIENTS: The original trial enrolled 314 patients with heart failure who were aged 50 years or older and were taking at least one cardiovascular drug for heart failure; 122 patients received the pharmacist intervention (patient education, therapeutic monitoring, and communication with primary care providers), and 192 patients received usual care (regular follow-up with primary care providers). We analyzed the results of 281 patients who had available health literacy and adherence data. MEASUREMENTS AND MAIN RESULTS: Drug adherence was assessed over 9 months using electronic prescription container monitors on cardiovascular drugs. Health literacy was assessed using the Short Test of Functional Health Literacy in Adults (scores range from 0-36, with an adequate literacy score defined as ≥ 23). Taking adherence, defined as the percentage of prescribed drug doses taken by the patient compared with the number of doses prescribed by the physician, was assessed for each group. Patients were a mean ± SD of 63 ± 9 years old, 51% had less than 12 years of education, 29% had inadequate health literacy, and they received a mean ± SD of 11 ± 4 drugs. In the usual care group, taking adherence was greater among patients with adequate (69.4%) than those with inadequate (54.2%) health literacy (p=0.001). In the intervention group, the difference in taking adherence among patients with adequate (77.3%) and inadequate (65.3%) health literacy was not statistically significant (p=0.06). Among patients with inadequate health literacy, the intervention increased adherence (65%, 95% confidence interval [CI] 54-77%) by an order of magnitude similar to that of the baseline adherence of patients with adequate health literacy (69%, 95% CI 65-74%). Multivariable analysis supported the association between health literacy and adherence. CONCLUSION: In patients with heart failure, those with adequate health literacy have better adherence to cardiovascular drugs than those with inadequate health literacy. The pharmacist intervention improved adherence in patients with adequate and inadequate health literacy. Health literacy may be an important consideration in drug adherence interventions.

BACKGROUND: In 2006, Medicare beneficiaries had the opportunity to choose from multiple newly available Medicare prescription drug plans (PDPs). Many beneficiaries reported difficulty in finding helpful information, whereas others reported they never looked for information. OBJECTIVES: This study examines antecedents of beneficiary information-seeking behaviors when learning about Medicare part D and choosing a PDP by using the Wilson Model of Information Behavior as a conceptual framework. METHODS: A cross-sectional analysis of 7008 Medicare beneficiaries from the 2004 to 2005 Medicare Current Beneficiary Surveys was used to predict whether a beneficiary sought Medicare part D information and the number of information sources used among those who sought information. A negative binomial hurdle model was used to estimate the determinants of these outcomes. Particular attention was given to the roles of information need and patient activation in predicting the outcomes. RESULTS: The results show that beneficiaries stating a need for information were more likely to seek information (odds ratio [OR]=2.02) and use multiple information sources (incidence rate ratio [IRR]=1.13). Beneficiaries with low patient activation were less likely to seek information (OR=0.97) and use multiple information sources (IRR=0.98). CONCLUSIONS: Information need and patient activation are antecedents of both the decision to seek Medicare part D information and how beneficiaries seek information. Interventions aimed at improving Medicare part D-related information seeking and decision making should focus on helping beneficiaries identify their need for information accurately and increasing their level of activation.

In the U.S. pharmacoepidemiology and related health professions can potentially flourish with the congressional appropriation of $1.1 billion of federal funding for comparative effectiveness research (CER). A direct result of this legislation will be the need for sufficient numbers of trained scientists and decision-makers to address the research and implementation associated with CER. An interdisciplinary expert panel comprised mostly of professionals with pharmaceutical interests was convened to examine the knowledge, skills, and abilities to be considered in the development of a CER curriculum for the health professions focusing predominantly on pharmaceuticals. A limitation of the panel's composition was that it did not represent the breadth of comparative effectiveness research, which additionally includes devices, services, diagnostics, behavioral treatments, and delivery system changes. This bias affects the generalizability of these findings. Notwithstanding, important components of the curriculum identified by the panel included study design considerations and understanding the strengths and limitations of data sources. Important skills and abilities included methods for adjustment of differences in comparator group characteristics to control confounding and bias, data management skills, and clinical skills and insights into the relevance of comparisons. Most of the knowledge, skills, and abilities identified by the panel were consistent with the training of pharmacoepidemiologists. While comparative effectiveness is broader than the pharmaceutical sciences, pharmacoepidemiologists have much to offer academic and professional CER training programs. As such, pharmacoepidemiologists should have a central role in curricular design and provision of the necessary training for needed comparative effectiveness researchers within the realm of pharmaceutical sciences.

BACKGROUND: High prescription copayments may create barriers to care, resulting in medication nonadherence. Although many studies have examined these associations in commercially insured patients with chronic disease, few have examined ß-blocker effects in heart failure patients. OBJECTIVE: Associations between ß-blocker prescription copayment levels and medication nonadherence were examined within commercially insured beneficiaries with a diagnosis of heart failure. METHODS: Heart failure patients were identified as those with at least 1 inpatient claim or 2 outpatient claims with an associated International Classification of Diagnosis, 9th Edition (ICD-9) code of 428.x, in addition to those with at least 2 ß-blocker claims. Copayment levels were defined in using $5.00 (USD) interval categories, and adherence was defined using the medication possession ratio (MPR). Ordinary least squares (OLS), fixed effects (FE), and random effect (RE) models were used to estimate associations between copayment level and MPR. Logistic regression was used to estimate the probability of nonadherence (MPR < 0.80) conditional upon copayment level. Regressions controlled for patient demographics, health status, prior hospitalizations, and concomitant medication use. RESULTS: The highest ß-blocker copayment level ($26+) had an average MPR that was 0.07 (95% CI, -0.11 to -0.03), 0.08 (95% CI, -0.12 to -0.04), and 0.09 (95% CI, -0.17 to -0.02) units lower than ß-blocker copayment level ($0 to $1) in the OLS, RE, and FE models, respectively. Copayment levels $21-$25 and $26+ were significantly associated with an increased risk of medication nonadherence (OR = 1.64; 95% CI, 1.1-2.4; and OR = 2.5; 95%, CI 1.6-4, respectively). CONCLUSIONS: Commercially insured heart failure patients aged ≥50 years who are prescribed higher costing ß-blockers may have up to an average 9% decrease in annual ß-blocker medication supply as well as an increased risk of nonadherence (MPR <0.80). Results need to be interpreted with caution given the potential of selection bias due to selective prescribing. Associations between copayment levels and nonadherence need to be further explored given the adverse health consequences of nonadherence to ß-blockers.

BACKGROUND: The purpose of this study was to evaluate the reliability, validity, and responsiveness to change of the Health Utilities Index Mark-3 (HUI-3) in heart failure (HF) for use in cost-effectiveness studies. METHODS AND RESULTS: Two hundred eleven patients with HF recruited from outpatient clinics were enrolled; 165 completed the 26-week study. Patients completed 4 health-related quality of life questionnaires (baseline and 4, 8, and 26 weeks), including the HUI-3, the Medical Outcomes Study Short-form 12 (SF-12), the Minnesota Living with Heart Failure Questionnaire (LHFQ), and the Chronic Heart Failure Questionnaire (CHQ). The HUI-3 indicated moderate or fair health-related quality of life overall; the attributes most impaired were pain, ambulation, cognition, and emotion. Internal consistency reliability (Cronbach's alpha = 0.51) was low and test-retest reliability (intraclass correlation coefficient = 0.68) was adequate. The HUI-3 total score was significantly associated with the SF-12, LHFQ, and CHQ total scores. It discriminated among patients with varying New York Heart Association class (P < .001) and varying perceived health (P < .001). The HUI-3 was less responsive to perceived change in health condition than the LHFQ or the CHQ. CONCLUSIONS: The HUI-3 demonstrated satisfactory reliability and validity in this sample supporting its use in cost-effectiveness studies.

It stands to reason that pharmacists would have a beneficial role in the treatment of patients with chronic illnesses wherein complicated pharmacotherapies are required to reduce the risk of acute exacerbation. For chronic heart failure, recent evidence bears this out. When pharmacists take time to provide self-care instructions for patients with heart failure or take part in collaborative healthcare teams, the need for costly urgent healthcare decreases with corresponding decreases in healthcare costs. Further research is needed to address the key supportive roles of pharmacists in the treatment of patients with heart failure.

In 2003, the Indiana Office of Medicaid Policy and Planning launched the Indiana Chronic Disease Management Program (ICDMP), a programme intended to improve the health and healthcare utilization of 15,000 Aged, Blind and Disabled Medicaid members living with diabetes and/or congestive heart failure in Indiana. Within ICDMP, programme components derived from the Chronic Care Model and education based on an integrated theoretical framework were utilized to create a telephonic care management intervention that was delivered by trained, non-clinical Care Managers (CMs) working under the supervision of a Registered Nurse. CMs utilized computer-assisted health education scripts to address clinically important topics, including medication adherence, diet, exercise and prevention of disease-specific complications. Employing reflective listening techniques, barriers to optimal self-management were assessed and members were encouraged to engage in health-improving actions. ICDMP evaluation results suggest that this low-intensity telephonic intervention shifted utilization and lowered costs. We discuss this patient-centred method for motivating behaviour change, the theoretical constructs underlying the scripts and the branched-logic format that makes them suitable to use as a computer-based application. Our aim is to share these public-domain materials with other programmes.

BACKGROUND: Patients with heart failure who take several prescription medications sometimes have poor adherence to their treatment regimens. Few interventions designed to improve adherence to therapy have been rigorously tested. OBJECTIVE: To determine whether a pharmacist intervention improves medication adherence and health outcomes compared with usual care for low-income patients with heart failure. DESIGN: Randomized, controlled trial conducted from February 2001 to June 2004. SETTING: University-affiliated, inner-city, ambulatory care practice. PATIENTS: 314 low-income patients 50 years of age or older with heart failure confirmed by their primary care physician. INTERVENTION: Patients were randomly assigned to intervention (39% [n = 122]) or usual care (61% [n = 192]) groups and were followed for 12 months. A pharmacist provided a 9-month multilevel intervention, with a 3-month poststudy phase. An interdisciplinary team of investigators designed the intervention to support medication management by patients who have low health literacy and limited resources. MEASUREMENTS: Primary outcomes were adherence, as measured by using electronic prescription monitors, and exacerbations requiring emergency department care or hospital admission. Secondary outcomes included health-related quality of life, patient satisfaction with pharmacy services, and total direct costs. RESULTS: During the 9-month intervention period, medication adherence was 67.9% and 78.8% in the usual care and intervention groups, respectively (difference, 10.9 percentage points [95% CI, 5.0 to 16.7 percentage points]). However, these salutary effects dissipated in the 3-month postintervention follow-up period, in which adherence was 66.7% and 70.6%, respectively (difference, 3.9 percentage points [CI, -5.9 to 6.5 percentage points]). Medications were taken on schedule 47.2% of the time in the usual care group and 53.1% of the time in the intervention group (difference, 5.9 percentage points [CI, 0.4 to 11.5 percentage points]), but this effect also dissipated at the end of the intervention (48.9% vs. 48.6%, respectively; difference, 0.3 percentage point [CI, -5.9 to 6.5 percentage points]). Emergency department visits and hospital admissions were 19.4% less (incidence rate ratio, 0.82 [CI, 0.73 to 0.93]) and annual direct health care costs were lower ($-2960 [CI, $-7603 to $1338]) in the intervention group. LIMITATIONS: Because electronic monitors were used to ascertain adherence, patients were not permitted to use medication container adherence aids. The intervention involved 1 pharmacist and a single study site that served a large, indigent, inner-city population of patients. Because the intervention had several components, intervention effects could not be attributed to a single component. CONCLUSIONS: A pharmacist intervention for outpatients with heart failure can improve adherence to cardiovascular medications and decrease health care use and costs, but the benefit probably requires constant intervention because the effect dissipates when the intervention ceases. ClinicalTrials.gov registration number: NCT00388622.

STUDY OBJECTIVES: To determine the rates of undersupply, appropriate supply, and oversupply of antihypertensive drugs, as measured by refill adherence, among patients with complicated and uncomplicated hypertension (i.e., patients who have and have not, respectively, experienced hypertension-related target organ damage), and to examine the association of refill adherence with hospitalization and health care costs among these patients. DESIGN: Retrospective analysis of electronic medical records. SETTING: An urban, public health care system. PATIENTS: A total of 15,206 patients aged 18 years or older whose electronic medical records indicated a clinical diagnosis of hypertension based on the International Classification of Diseases, Ninth Revision, Clinical Modification codes, and who had received at least one prescription of an antihypertensive drug from 1995-2001. MEASUREMENTS AND MAIN RESULTS: We used multivariable analyses to investigate the association of refill adherence with hospitalization and costs. On average, 53% of patients had appropriate supplies (80-120% of supplies needed), 7% had undersupplies, and 40% had oversupplies of drug annually. For patients with complicated hypertension, an undersupply of drug was associated with a 15% greater probability (p=0.009) and an oversupply with a 16% greater probability (p<0.0001) of hospitalization. Among those with uncomplicated hypertension, oversupply was associated with an 11% greater probability (p=0.0002) of hospitalization; undersupply was not associated with greater probability of hospitalization. Total health care costs were lower for patients with undersupplies and higher for those with oversupplies of drug. CONCLUSION: Among adults in an urban health care system with complicated hypertension, both undersupply and oversupply of drug were associated with increased hospitalization rates. Monitoring refill adherence of patients, particularly those with low income, minority status, and complicated hypertension, may be useful for targeting patients with undersupplies of drug to encourage refill adherence and identifying patients with oversupplies, who are at high risk of hospitalization.

The Indiana Chronic Disease Management Program (ICDMP) is intended to improve the quality and cost-effectiveness of care for Medicaid members with congestive heart failure (chronic heart failure), diabetes, asthma, and other conditions. The ICDMP is being assembled by Indiana Medicaid primarily from state and local resources and has seven components: (1) identification of eligible participants to create regional registries, (2) risk stratification of eligible participants, (3) nurse care management for high-risk participants, (4) telephonic intervention for all participants, (5) an Internet-based information system, (6) quality improvement collaboratives for primary care practices, and (7) program evaluation. The evaluation involves a randomized controlled trial in two inner-city group practices, as well as a statewide observational design. This article describes the ICDMP, highlights challenges, and discusses approaches to its evaluation.

OBJECTIVE: To determine how professional characteristics and practices of physicians alter the selection of medical treatments involving multiple alternatives. Situations involving multiple alternatives can increase the difficulty of making a decision, resulting in more choice deferral than when fewer alternatives are available. DESIGN, SETTING, PARTICIPANTS: A survey and scenario were mailed to a random sample of 314 primary and emergency care physicians affiliated with the Indiana University Medical Center. Using a scenario involving treatment decisions for a patient with osteoarthritis, the effects of multiple treatment alternatives on decision making were explored. Other physician factors included experience, workload, fatigue, continuing education, and supervision. MAIN OUTCOME MEASURES: Physicians' treatment decisions. RESULTS: Physician response was 61% (n = 192). In contrast to previous studies, physicians in the present study were equally likely to prescribe a new medication, regardless of whether they were deciding about 1 medication or between 2 similar medications (54.5% v. 56.0%, P = 0.841). However, physicians who supervise medical students were far less influenced by the cognitive bias associated with multiple choices than those who did not supervise medical students. Supervising physicians were more likely to defer making a decision when there was only 1 treatment option than when there were 2 (49.3% v. 37%, P = 0.143), whereas the opposite was true for nonsupervising physicians (33.3% v. 63%, P = 0.040). The number of hours spent supervising medical students and the number of years as a physician were also important factors in the decision-making process. CONCLUSIONS: Multiple treatment alternatives may result in a deferral of choice. However, this cognitive bias is attenuated by experience and supervision, thus enhancing decision making. Implicit and explicit learning gained through experience and the supervisory process appears to be a central mechanism by which the physicians are protected from this cognitive bias.

Patients with heart failure are required to comply with a medication regimen and dietary sodium restrictions. The objectives of this study were to determine the most frequently perceived benefits of and barriers to compliance with medication and dietary sodium restrictions and evaluate the relevancy of these scale items for testing in tailored intervention studies. Data were collected as part of two studies that evaluated the psychometric properties of two questionnaires. The most frequently identified benefit of medication compliance was decreasing the chance of being hospitalized, and the most commonly reported barrier was disruption of sleep. Patients were knowledgeable about the benefits of compliance with dietary sodium restrictions, and the poor taste of food on the low sodium diet was the most common barrier. Heart failure patients perceive benefits of and barriers to compliance with therapeutic regimens that are likely to be amenable to tailored interventions designed to enhance compliance.

OBJECTIVE: The objective of this study was to compare the ability of risk stratification models derived from administrative data to classify groups of patients for enrollment in a tailored chronic disease management program. SUBJECTS: This study included 19,548 Medicaid patients with chronic heart failure or diabetes in the Indiana Medicaid data warehouse during 2001 and 2002. MEASURES: To predict costs (total claims paid) in FY 2002, we considered candidate predictor variables available in FY 2001, including patient characteristics, the number and type of prescription medications, laboratory tests, pharmacy charges, and utilization of primary, specialty, inpatient, emergency department, nursing home, and home health care. METHODS: We built prospective models to identify patients with different levels of expenditure. Model fit was assessed using R statistics, whereas discrimination was assessed using the weighted kappa statistic, predictive ratios, and the area under the receiver operating characteristic curve. RESULTS: We found a simple least-squares regression model in which logged total charges in FY 2002 were regressed on the log of total charges in FY 2001, the number of prescriptions filled in FY 2001, and the FY 2001 eligibility category, performed as well as more complex models. This simple 3-parameter model had an R of 0.30 and, in terms in classification efficiency, had a sensitivity of 0.57, a specificity of 0.90, an area under the receiver operator curve of 0.80, and a weighted kappa statistic of 0.51. CONCLUSION: This simple model based on readily available administrative data stratified Medicaid members according to predicted future utilization as well as more complicated models.

OBJECTIVE: To assess the agreement between 2 methods of assigning New York Heart Association (NYHA) functional class to patients with chronic heart failure (CHF): deriving NYHA class from self-report interview data versus clinician assignment. To then determine the ability of each method to predict all-cause hospitalization. METHODS: Adults with CHF > or = 50 years old from an urban health system in Indianapolis, Indiana, were administered the Kansas City Cardiomyopathy Questionnaire (a validated CHF symptom questionnaire) at baseline. Patient self-reported functional data were then used to derive NYHA class. Clinical providers who were blinded to patients' questionnaire data independently assessed NYHA functional class. We used a weighted kappa statistic to evaluate the agreement between the NYHA class from patient-derived and that from provider-assigned methods. We then assessed the ability of patient and provider NYHA to predict time to hospitalization using Cox proportional hazards models. RESULTS: Of 156 patients with complete 6-month follow-up (mean age 63 years +/- 9 SD, 53% African American, and 68% women), the correlation coefficient was 0.43 between the patient-derived and provider-assigned NYHA methods. The weighted kappa statistic was 0.278, and the 95% confidence interval was 0.18 to 0.37, indicating only slight agreement. Patients classified themselves in worse categories than did their providers. Provider-assigned NYHA was a better predictor of hospitalization (P = .06). CONCLUSIONS: There is only slight agreement between patient-derived and clinician-assigned NYHA functional class. A different approach with patients may be needed if providers hope to use patients' reports to identify those at risk for hospitalization.

BACKGROUND: Adults aged > or =50 years often have multiple chronic diseases requiring multiple medications. However, even drugs with well-documented benefits are often not taken as prescribed, for a variety of reasons. OBJECTIVE: The objective of this article was to provide background information about medication adherence and its measurement, the development of the conceptual model for use in adherence research, and supportive intervention strategies such as pharmaceutical care by pharmacists to improve chronic medication use in older adults. METHODS: English-language literature published from 1990 to 2000 was searched on MEDLINE, International Pharmaceutical Abstracts, and AARP Ageline using the terms aged, heart failure, CHF, adherence, chronic heart failure, compliance, and related terms. The authors used their personal files and libraries to obtain seminal literature and textbooks published before 1990. RESULTS: Although the cognitive processes needed to manage and take medications decline with aging, the number of prescription and nonprescription medications consumed increases. Other factors such as vision, hearing, health literacy, disability, and social and financial resources may all complicate the ability of older adults to adhere to the pharmacologic prescription. CONCLUSIONS: Many factors are associated with medication adherence and related health outcomes in older adults. Therefore, strategies to improve adherence will need to be multidimensional, including improvements in pharmacy services that consider age-related factors (eg, declining cognitive and physical functions) as well as a variety of environmental and social factors.
