Older people and adherence with medication: a review of the literature

Cost-Related Medication Nonadherence (CRN) on Healthcare Utilization and Patient-Reported Outcomes: Considerations in Managing Medicare Beneficiaries on Antidepressants

Background: Many patients face a financial burden due to their medications, which may lead to poor health outcomes. The behaviors of non-adherence due to financial difficulties, known as cost-related medication non-adherence (CRN), include taking smaller doses of drugs, skipping doses to make prescriptions last longer, or delaying prescriptions. To date, the prevalence of CRN remains unknown, and there are few studies about the association of CRN on self-reported healthcare utilization (Emergency room (ER) visits and outpatient visits) and self-reported health outcomes (health status and disability status) among older adults taking antidepressants. Objectives: The objectives were to 1) examine the CRN prevalence, and 2) determine the association of CRN on self-reported healthcare utilization and self-reported health outcomes. Methods: This study was a cross-sectional study of a sample of older adults from the Medicare Current Beneficiary Survey (MCBS) who reported having used antidepressants in 2017. Four logistic regressions were implemented to evaluate the association of CRN, and self-reported healthcare utilization and self-reported health outcomes. Results: The study identified 602 participants who were Medicare beneficiaries on antidepressants. The prevalence of CRN among antidepressant users was (16.61%). After controlling for covariates, CRN was associated with poorer self-reported outcomes but not statistically significant: general health status [odds ratio (OR): 0.67; 95% confidence interval (CI): 0.39-1.16] and disability status (OR: 1.34; 95% CI: 0.83-2.14). In addition, CRN was associated with increased outpatient visits (OR: 1.89; 95% CI: 1.19-3.02), but not associated with ER visits (OR: 1.10; 95% CI: 0.69-1.76). Conclusion: For Medicare beneficiaries on antidepressants, CRN prevalence was high and contributed to more outpatient visits. The healthcare provider needs to define the reasoning for CRN and provide solutions to reduce the financial burden on the affected patient. Also, health care providers need to consider the factors that may enhance patient health status and healthcare efficiency.

The association between medication non-adherence and adverse health outcomes in ageing populations: A systematic review and meta-analysis

AIMS

The aim of this systematic review and meta-analysis was to synthesise the evidence relating to medication non-adherence and its association with health outcomes in people aged ≥50 years.

METHODS

Seven databases were searched up to February 2019 for observational studies that measured medication (non-)adherence as a predictor of the following health outcomes in adults aged ≥50 years: healthcare utilisation (hospitalisation, emergency department visits, outpatient visits and general practitioner visits), mortality, adverse clinical events and quality of life. Screening and quality assessment using validated criteria were completed by 2 reviewers independently. Random effects models were used to generate pooled estimates of association using adjusted study results. The full methodological approach was published on PROSPERO (ID: CRD42017077264).

RESULTS

Sixty-six studies were identified for qualitative synthesis, with 11 of these studies eligible for meta-analyses. A meta-analysis including 3 studies measuring medication non-adherence in adults aged ≥55 years showed a significant association with all-cause hospitalisation (adjusted odds ratio 1.17, 95% confidence interval [CI] 1.12, 1.21). A meta-analysis including 2 studies showed that medication non-adherence was not significantly associated with an emergency department visit (adjusted odds ratio 1.05, 95% CI 0.90, 1.22). Good adherence was associated with a 21% reduction in long-term mortality risk in comparison to medication non-adherence (adjusted hazard ratio 0.79, 95% CI 0.63, 0.98).

CONCLUSION

Medication non-adherence may be significantly associated with all-cause hospitalisation and mortality in older people. Medication adherence should be monitored and addressed in this cohort to minimise hospitalisation, improve clinical outcomes and reduce healthcare costs.

Adherence to Lenalidomide in Older Adults With Newly Diagnosed Multiple Myeloma

INTRODUCTION

One of the most common orally administered antimyeloma agents, lenalidomide, has significantly improved outcomes in multiple myeloma, including in older patients. However, despite its utilization and cost, the rates and factors related to adherence to lenalidomide in older adults with newly diagnosed multiple myeloma remain unknown.

PATIENTS AND METHODS

Data were collected from adults with newly diagnosed multiple myeloma over age 65 years being treated with lenalidomide therapy between the years 2007 and 2014 in the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked databases. Adherence was measured as medication possession ratio (MPR), which was defined as the ratio of the number of days the patient had pills in their possession to the number of days in the observation period in the first year after myeloma diagnosis. MPR of < 90% was considered poor adherence.

RESULTS

A total of 793 patients were included in the analysis. The mean MPR in our cohort was 89.5 ± 9.3%. Overall, 38% (n = 302) of the patients were considered to have poor adherence. Factors associated with poor adherence included increasing age (adjusted odds ratio [aOR] = 1.03 per year; 95% confidence interval [CI], 1.00-1.05; P = .024), black race (aOR = 1.72; 95% CI, 1.08-2.73; P = .022), and polypharmacy (aOR = 1.04 per medication; 95% CI, 1.01-1.08; P = .008).

CONCLUSION

Over a third of older adults with newly diagnosed multiple myeloma were considered to have poor adherence to lenalidomide, using the MPR as a surrogate for adherence. This highlights the need to further understand factors and devise strategies to support adherence in this patient cohort.

Demonstrating a Technology-Mediated Intervention to Support Medication Adherence in Community-Dwelling Older Adults in Primary Care: A Feasibility Study

Background: Medication non-adherence can lead to significant morbidity and mortality. This 4-week feasibility study aims to demonstrate that the eDosette intervention can be implemented with older adults in primary care. Method: Fifty-six older adults from four primary care sites in Southwestern Ontario, Canada participated. The intervention involved generating, for pharmacist review, weekly medication administration records based on transmitted data captured by the eDosette. The primary outcome is implementation feasibility defined by recruitment, adherence rates, frequency of captured missed and late doses, descriptions of clinical work resulting from the intervention, and participant feedback. Results: The recruitment rate was 24% (57/240); one withdrew due to personal reasons. The mean observed adherence rate was 82% (range 49%-100%). Overall, participants missed 505 and took 2,105 doses late; 118 clinical decisions occurred with 72 unique medication changes in 31 participants. Participants found the eDosette easy to use and did not feel that they were viewed negatively because of their potential non-adherence. Conclusion: The eDosette intervention could be feasibly implemented in primary care with older adults. Providing information about when an older adult takes their medications could play a role in medication adherence by prompting more informed discussions between the older adult and primary care clinicians.

High adherence of patients with multiple myeloma who receive treatment with immunomodulatory drugs (IMIDS) in hematology/oncology group practices in Germany

PURPOSE

Immunomodulatory drugs (IMIDS) have changed the treatment and outcome of patients suffering from multiple myeloma. However, with the oral administration adherence becomes an issue. Since there is no "gold standard" in measuring adherence, we assessed the adherence of myeloma patients with the help of different data sources.

METHODS

All patients who have been receiving IMIDS for at least 3 months were eligible. Computer assisted personal interviews of patients and, if possible, their caregivers were carried out. Attending oncologists evaluated the patient's adherence with the help of a standardized questionnaire. In addition, a retrospective analysis of prescription data was conducted. All data were analyzed statistically using SPSS.

RESULTS

One hundred myeloma patients, 35% female, 65% male, with a median age of 70 years (37-86) were interviewed. Prescription data could be evaluated in terms of adherence in 78 patients (78%), 56 caregivers could be questioned (56%). Ninety-seven percent of patients rated themselves as adherent in taking IMIDS. Data from treating oncologists, caregivers and prescriptions supported this result. IMID therapies were rated as very effective and significant, toxicities were acceptable and dosing regimens simple/uncomplicated.

CONCLUSIONS

Myeloma patients seem to be highly adherent to IMID treatments.

Community pharmacy Medicines Use Review: current challenges

With a growing aging population, the appropriate, effective, and safe use of medicines is a global health policy priority. One concern is patients' non-adherence to medicines, which is estimated to be up to 50%. Policymakers seek to reconfigure medicine management services and consider community pharmacy as especially well-placed to improve medicine use. In England and Wales, a commissioned medication review service called "Medicines Use Reviews (MURs)" was made available in through the National Health Service (NHS) in 2005. This involves a patient-pharmacist consultation to improve patients' knowledge and the use of medicines and to help reduce avoidable waste. However, over a decade since their introduction, questions remain over the extent to which the MUR policy has successfully been embedded in practice and translated into more effective use of medicines. The MUR intervention continues to hold many challenges ranging from poor public awareness and acceptance of MURs, organizational constraints, and issues over interprofessional collaboration. Many of these challenges are not exclusive to the MUR service, or even to the community pharmacy setting. Nevertheless, by identifying and exposing such challenges, an opportunity exists for policymakers and commissioners to seek to improve this service to patients. This narrative review explores the current challenges that face MURs. Damschroder et al's consolidated framework for implementation research is employed to help organize these challenges from patient and professional perspectives across multiple contexts. Over the past decade, MUR policy and practice has continued to evolve, being shaped by research, organizational and professional influences, and policy. Reforms to the service suggest that the MURs are becoming more responsive to patients' need and preferences. It is intended that this review will create impetus and scope for further debate, service reconfiguration, and ultimately service improvement.

Glaucoma, dementia, and the "precipice of care": transitions between states of medication adherence

PURPOSE

"She wouldn't remember. Even when I go through, and she's decided to go to bed, I'll say I'll come and do her drops. If I didn't say that, they wouldn't be done." Dementia is widely considered as a key factor in whether patients take their medication as prescribed. However, few studies have examined the effect of dementia on medication management strategies for glaucoma including how patient and carer needs impact adherence and long-term prognosis. We report findings from a qualitative grounded theory study incorporating the views of patients, carers, and healthcare professionals.

METHODS

Eighty-three semistructured interviews were conducted with 35 patients, 22 lay carers, and nine healthcare professionals across sites in Wales and Scotland. These explored understanding of eye drop regimens, barriers, and facilitators to drop administration, as well as attitudes toward glaucoma, dementia, and other comorbidities.

RESULTS

Using Pound's synthesis of adherence behavior, we identified categories of active and passive acceptance of medicines, alongside modification or rejection of eye drop regimens. In relation to dementia, participants highlighted transitions between such categories, with a shift from active to passive acceptance commonly reported. This loss of self-medicating capability was referred to as the precipice of care, where entwinement of multiple conditions (eg, heart disease, glaucoma, and dementia) and sociocultural influences (eg, living alone) contributed to accelerated health declines. That said, numerous factors mitigated this, with a key role being the lay carer. Spouses and family members often acted as the monitor of eye drops for patients, seeking intervention when any behavioral changes influenced their administration.

CONCLUSION

Though dementia was associated with progression toward the precipice of care, factors such as communication with healthcare professionals appeared to affect patient adherence. Recommendations for healthcare practice include better recording of dementia diagnoses and integrating eye drops into preexisting routines.

Theoretical foundations of adherence behaviors: synthesis and application in adherence to oral oncology agents

BACKGROUND

The use of theory can provide structure for understanding the dynamics of adherence to oral agents for cancer (OACs) and facilitate the development of strategies for patient assessment and care planning related to oral adherence.

OBJECTIVES

The focus of this article is to identify common theories pertinent to medication-taking behavior, as well as their applications toward assessment and care planning regarding adherence to OACs. Approaches to apply these theories and their concepts in clinical practice are identified.

METHODS

Theories applied to adherence behaviors were reviewed, and their concepts were compared and synthesized. These concepts were then applied to medication adherence behavior.

FINDINGS

Various theories can help healthcare providers to better understand the influences and determinants of patients' adherence decisions and behaviors. They can then be used to structure assessment and plan related aspects of care.

Factors influencing oral adherence: qualitative metasummary and triangulation with quantitative evidence

BACKGROUND

Concern about adherence to oral agents among patients with cancer has grown as more oral agents are being used for cancer treatment. Knowledge of common factors that facilitate or inhibit adherence to oral medication regimens can be beneficial to clinicians in identifying patients at risk for nonadherence, in planning care to address barriers to adherence, and in educating patients about ways to improve adherence.

OBJECTIVES

The focus of this review is to synthesize the evidence about factors that influence adherence and identify implications for practice.

METHODS

Literature was searched via PubMed and CINAHL®. Evidence regarding factors influencing adherence was synthesized using a metasummary of qualitative research and triangulated with findings from quantitative research.

FINDINGS

Forty-four factors influencing adherence were identified from 159 research studies of patients with and without cancer. Factors associated with adherence in oncology and non-oncology cases included provider relations, side effects, forgetfulness, beliefs about medication necessity, establishing routines for taking medication, social support, ability to fit medications in lifestyle, cost, and medication knowledge. Among patients with cancer, depression and negative expectations of results also were shown to have a negative relationship to adherence.

Factors influencing adherence in CML and ways to improvement: Results of a patient-driven survey of 2546 patients in 63 countries

Optimal adherence to CML therapy is of key importance to maximize treatment effectiveness. Two clinical studies (ADAGIO and Hammersmith) have proven a clear correlation between adherence and achieving optimal treatment response and have revealed that non-adherence is common in CML patients (Marin et al. in J Clin Oncol 28(24):2381-2388, 2010, Noens et al. in Haematologica 99(33):437-447, 2014). The aim of this study is to assess the extent of suboptimal adherence and to investigate motivations and behavioural patterns of adherence in a worldwide patient sample. Questionnaires were provided by the CML Advocates Network and were filled in by patients online and offline. Patient characteristics, treatment and motivations were collected. Adherence was assessed by the 8-item Morisky Medication Adherence scale. Logistic regression models were fitted to investigate the influence of different factors on adherence. Overall, 2 546 questionnaires from 63 countries and 79 CML patient organisations were evaluable. 32.7% of participants were highly adherent, 46.5% were in the medium and 20.7% in the low adherence group. Factors increasing the probability of being in the high adherence group are older age, male sex, management of side effects, only one tablet per day and feeling well informed about CML by the doctor. More than 2 years since diagnosis were significantly lowering the chance as was the use of reminding tools. Living arrangements, multiple medication and personal payment obligations increased the probability to be at least in the medium adherent group. This is the most comprehensive study conducted to date to gain knowledge about factors causing non-adherence in CML. Better information on the disease, medication and management of side effects, supported by haematologists, is key to improve adherence.

Developing and testing an electronic medication administration monitoring device for community dwelling seniors: a feasibility study

Background

Medication non-adherence, polypharmacy, and adverse drug events are major healthcare issues leading to significant morbidity, mortality, and healthcare expenditures. Currently, there are no methods to systematically track medication usage in community-dwelling seniors. The eDosette prototype was created to make medication use patterns visible via the Internet. This study aims to demonstrate feasibility, usability, and acceptability of the eDosette in community-dwelling seniors in primary care.

Methods

A 2-week feasibility study involving a convenience sample of 10 patients from an academic family medicine teaching unit in Hamilton, Ontario, Canada, was conducted over a 6-month period between April and October 2015. The eDosette transmitted hourly electronic data via the Internet on each participant’s pattern of medication use; this data was converted into an individualized medication administration record (MAR). Based on the MARs from the 10 participants, the frequency of missed medication doses, the time of dose administration, and each participant’s adherence rate for their prescribed medications could be determined. A medication adherence survey and a patient usability and acceptability survey were administered to all the participants of the study.

Results

The eDosette was able to record a participant’s medication use and transmit this data electronically via the Internet with sufficient quality to create participant-specific MARs. A total of 418 doses were captured by the eDosette throughout the study; only 5% (n = 22 doses) were missing information or had poor image quality. Analysis of the MARs revealed that 19% (n = 79 doses) were taken outside a 2-h window of the average dose administration time, and two doses were completely missed by all participants during this feasibility study. Participant feedback found the eDosette easy and acceptable to use. Participant feedback also identified hardware and software issues that require attention prior to a larger study.

Conclusions

The eDosette is a feasible and novel technology that can be successfully installed into the homes of community-dwelling seniors to help in monitoring actual medication use patterns. This study provided details for further device development and evidence to support the need for a larger pilot study on the eDosette’s impact on medication adherence.

The association between family caregivers' involvement in managing older adults' medications and caregivers' information-seeking behavior

OBJECTIVES

1) To explore the association between family caregivers' involvement in managing care recipients' medications and their information-seeking behavior related to caregiving; and 2) to examine the sources used by caregivers when seeking information.

METHODS

A retrospective analysis of cross-sectional data from 2 national studies, the 2011 National Health and Aging Trends Study (NHATS) and its supplement, the National Study of Caregiving (NSOC), was conducted. A nationally representative sample of community-dwelling adults (≥65 years of age) completed NHATS interviews, and a sample of their family caregivers participated in NSOC. Caregiver involvement in medication management was assessed with the use of 2 items asking caregivers if they helped keep track of care recipients' medications or helped with injecting medications. Information seeking was assessed with the use of an item asking caregivers if they ever looked for caregiving-related information.

RESULTS

Out of 1367 caregivers interviewed, 54% reported helping to keep track of care recipients' medications and 8.7% assisting with injecting medications. Approximately 10.2% (n = 149) of caregivers reported seeking information to help them care for their care recipients. Caregivers sought information primarily on their own either through online resources or asking friends or relatives (73.3%). Sixty-four percent also sought information from medical providers or social workers. Adult children of caregivers were more likely to seek information for their older adult parents, based on bivariate analysis (P <0.01). In multivariable-adjusted models, caregivers who helped to keep track of medications had 2.30 (95% confidence interval [CI] 1.18 to 4.51) times higher odds of seeking information to help them to provide care for their care recipients. Caregivers helping with injecting medications were less likely to seek information (odds ratio 0.32, 95% CI 0.14 to 0.76).

CONCLUSION

Specific caregiver responsibilities, such as assisting with medication management activities, are associated with caregivers' information-seeking behavior related to care recipients' health. Health care providers, including pharmacists, can play an important role in helping caregivers to identify proper resources for information and in educating them about medication management.

Adherence assessment of patients with metastatic solid tumors who are treated in an oncology group practice

Due to the increase of oral agents nonadherence is an emerging challenge in cancer care. We evaluated how well different assessments match and how adherence could be measured in routine care. For this purpose patients suffering from metastatic solid tumors who were treated with oral anticancer drugs in an oncology group practice were surveyed. Attending oncologists answered a questionnaire, too, and a retrospective analysis of prescription data was conducted. Caregivers who were eligible for an interview were surveyed additionally. 128 patients (70 % female) with a median age of 69 years (36-88) took part, 95 % of all approached patients. 56 % suffered from metastatic breast cancer, 44 % from other metastatic solid tumors. 65 caregivers (60 % female) with a median age of 62 years (21-82) were interviewed as well. Patients were assessed in 84 % as very reliable in medication-taking by their oncologists. This high adherence rate was supported by patients, caregivers and prescription data. However, concordance between assessments of patients, caregivers and oncologists was not substantial. Our method of considering different perspectives to assess adherence has to be improved and validated but could help to evaluate adherence with oral cancer therapy in routine care.

Medication regimen complexity in adults and the elderly in a primary healthcare setting: determination of high and low complexities

Background:

The complexity of a medication regimen is related to the multiple characteristics of the prescribed regimen and can negatively influence the health outcomes of patients.

Objective:

To propose cut-off points in the complexity of pharmacotherapy to distinguish between patients with low and high complexities seen in a primary health care (PHC) setting to enable prioritization of patient management.

Methods:

This is a cross-sectional study, which included 517 adult and elderly patients, analyzing different cut-off points to define the strata of low and high pharmacotherapy complexities based on percentiles of the population evaluated. Data collection began with the solicitation of prescriptions, followed by a questionnaire that was administered by an interviewer. The complexity of a medication regimen was estimated from the Medication Regimen Complexity Index (MRCI). High complexity pharmacotherapy scores were analyzed from patient profiles, the use of health services, and pharmacotherapy. The criteria for subject inclusion in the sample population were as follows: inhabitant of the area covered by the municipality, 18 years or older, and being prescribed at least one drug during the collection period. Exclusion criteria at the time of collection were the use of any medication whose prescription was not available. All medications were accessed through the Primary Healthcare Service (PHS).

Results:

The median total pharmacotherapy complexity score was 8.5. High MRCI scores were correlated with age, medications taken with in the Brazilian PHS, having at least one potential drug-related problem, receiving up to eight years of schooling, number of medications and polypharmacy (five or more medicines), number of medical conditions, number of medical appointments, and number of cardiovascular diseases and endocrine metabolic diseases. We suggest different complexity tracks according to age (e.g., adult or elderly) that consider the pharmacotherapy and population coverage characteristics as high complexity limits. For the elderly patients, the tracks were as follows: MRCI≥25.4, MRCI≥20.9, MRCI≥17.5, MRCI≥15.7, MRCI≥14.0, and MRCI≥13.0. For adult patients, the limits of high complexity were MRCI≥25.1; MRCI ≥ 23.8; MRCI≥21.0; MRCI≥17.0; MRCI≥16.5; and MRCI≥15.5.

Conclusion:

The medication regimen complexity is associated with the patient’s illness profile and problems with the use of drugs; therefore, the proposed scores can be useful in prioritizing patients for clinical care by pharmacists and other health professionals.

Correlation between the use of ‘over-the-counter’ medicines and adherence in elderly patients on multiple medications

BACKGROUND

Medication adherence is a multifaceted issue that is influenced by various factors. One factor may be the concurrent use of over-the-counter (OTC)medicines. The use of OTC medicine has been reported as common amongst elderly patients.

OBJECTIVE

To determine if a correlation exists between the use of OTC medicines and adherence to prescribed medications in elderly patients.

SETTING

Non-institutionalised elderly patients in Denmark.

METHODS

Elderly unassisted patients aged ≥65 prescribed five or more prescription drugs were included in the study. Information on the use of concurrent OTC medications (herbal medicines, dietary supplements, or non-prescribed drugs) was elicited during home visit interviews. Prescription drug adherence was determined by pill counts. A patient was categorised as non-adherent if the me an adherence rate for all drugs consumed was\80 %. Different sensitivity analyses were made where adherence was defined different.

MAIN OUTCOME MEASURE

Medication adherence based on pill-count.

RESULTS

A total of 253 participants included 72 % who used OTC medicines and 11 % who did not adhere to their prescriptions. Users of OTC medicines, however, were significantly more likely to be adherent than were non-users (odds ratio 0.41; 95 %confidence interval 0.18–0.91). Sensitivity analyses where adherence was defined different show no relationship between adherence and use of OTC medicine. Furthermore,separate analyses of herbal medicines, dietary supplements,or non-prescribed drugs did not correlate with adherence to prescriptions.

CONCLUSION

Amongst elderly patients on multiple medications a positive relationship was found between the overall use of OTC medicines and adherence to prescription drugs, in contrast to none when adherence were defined different or herbal medicines, dietary supplements, or non-prescribed drugs were analysed separately.

Expectations and user experience of a multimodal medicine management system for older users

Purpose

– The purpose of this paper is to analyse the adoption of a multimodal medication management system (MMS) targeted on older people and home care professionals. The paper aims to describe the expectations of the system and the user experience findings from an empirical qualitative field trial. The field trial results are used to discuss how MMSs should be designed in order to improve adherence to medications.

Design/methodology/approach

– The paper suggests that building a multimodal medicine management system targeted on both older users and home care professionals brings many benefits over electronic medicine dispenser systems or general reminder systems. The research process uses an iterative prototyping approach including phases of requirements analysis and concept design, prototype building and evaluation in a field trial.

Findings

– The study demonstrates how a system that merely satisfied users during the prototype building phase does not necessarily succeed as well as expected in the field trials. It would be important to consider reasons for medication non-adherence and non-technology factors influencing willingness to adopt new assistive devices in order to promote diffusion of new MMSs at home. The paper also discusses how the different persuasive functionalities of the system addressed patient-centred factors influencing non-adherence and how they could be addressed.

Research limitations/implications

– This study has some limitations. The actual adherence to medications was not measured. However, in the future, it will be important to study how the MMSs influence medication adherence. Also, the user experiences of the home care professionals were not studied in the field trials. Home care professionals who were involved in the user studies and trials merely estimated the value for their patients and not for themselves.

Originality/value

– This paper analyses design issues relevant when designing systems to help older people manage their medications.

Factors influencing adherence to cancer treatment in older adults with cancer: a systematic review

BACKGROUND

Cancer is a disease that mostly affects older adults. Treatment adherence is crucial to obtain optimal outcomes such as cure or improvement in quality of life. Older adults have numerous comorbidites as well as cognitive and sensory impairments that may affect adherence. The aim of this systematic review was to examine factors that influence adherence to cancer treatment in older adults with cancer.

PATIENTS AND METHODS

Systematic review of the literature published between inception of the databases and February 2013. English, Dutch, French and German-language articles reporting cross-sectional or longitudinal, intervention or observational studies of cancer treatment adherence were included. Data sources included MEDLINE, EMBASE, PsychINFO, Cumulative Index to Nursing and Allied Health (CINAHL), Web of Science, ASSIA, Ageline, Allied and Complementary Medicine (AMED), SocAbstracts and the Cochrane Library. Two reviewers reviewed abstracts and abstracted data using standardized forms. Study quality was assessed using the Mixed Methods Appraisal Tool 2011.

RESULTS

Twenty-two manuscripts were identified reporting on 18 unique studies. The quality of most studies was good. Most studies focused on women with breast cancer and adherence to adjuvant hormonal therapy. More than half of the studies used data from administrative or clinical databases or chart reviews. The adherence rate varied from 52% to 100%. Only one qualitative study asked older adults about reasons for non-adherence. Factors associated with non-adherence varied widely across studies.

CONCLUSION

Non-adherence was common across studies but little is known about the factors influencing non-adherence. More research is needed to investigate why older adults choose to adhere or not adhere to their treatment regimens taking into account their multimorbidity.

Managing older patients with coexistent asthma and chronic obstructive pulmonary disease: diagnostic and therapeutic challenges

Asthma and chronic obstructive pulmonary disease (COPD) are common obstructive airway diseases, especially among older people. These conditions are associated with a significant and increasing disease burden. The diagnosis and management of asthma and COPD in older populations are complex, and consequently clinicians are faced with many therapeutic and diagnostic challenges. Both aging and obstructive airway diseases are associated with complex co-morbidities and these coexisting illnesses confound management. Moreover, the age-related physiological changes that occur in the lungs may lead to airflow limitation, and this may be difficult to distinguish from an active disease state. In practice, management of asthma and COPD is informed by disease-specific clinical practice guidelines; however, most older people with these conditions are excluded from clinical trials that are designed to inform practice, creating major evidence gaps. Furthermore, seldom do clinical practice guidelines consider the complexities of management in older populations. The problems experienced by older people are complex and multifactorial and our approach to management must reflect these challenges. Opportunities exist to improve the management and outcomes for older people with obstructive airway disease and there is an urgent need for clinical trials to test management approaches in this population; current research must consider the challenges and evidence gaps that exist.

Improving medication adherence in chronic obstructive pulmonary disease: a systematic review

Adherence to medication among individuals with chronic obstructive pulmonary disease (COPD) is suboptimal and has negative impacts on survival and health care costs. No systematic review has examined the effectiveness of interventions designed to improve medication adherence. Electronic databases Medline and Cochrane were searched using a combination of MeSH and keywords. Eligible studies were interventions with a primary or secondary aim to improve medication adherence among individuals with COPD published in English. Included studies were assessed for methodological quality using the Effective Practice and Organisation of Care (EPOC) criteria. Of the 1,186 papers identified, seven studies met inclusion criteria. Methodological quality of the studies was variable. Five studies identified effective interventions. Strategies included: brief counselling; monitoring and feedback about inhaler use through electronic medication delivery devices; and multi-component interventions consisting of self-management and care co-ordination delivered by pharmacists and primary care teams. Further research is needed to establish the most effective and cost effective interventions. Special attention should be given to increasing patient sample size and using a common measure of adherence to overcome methodological limitations. Interventions that involve caregivers and target the healthcare provider as well as the patient should be further explored.

Older adults' satisfaction with a medication dispensing device in home care

INTRODUCTION

Older adults with multiple chronic conditions face the complex task of medication management involving multiple medications of varying doses at different times. Advances in telehealth technologies have resulted in home-based devices for medication management and health monitoring of older adults. We examined older adults' perceptions of a telehealth medication dispensing device as part of a clinical trial involving home healthcare clients, nurse coordination and use of the medication dispensing device.

METHODS

Ninety-six frail older adult participants who used the medication dispensing device for 12 months completed a satisfaction survey related to perceived usefulness and reliability. Results were analyzed and grouped by themes in the following areas: Ease of Use, Reliability, Medication Management Assistance, Routine Task Performance and Acceptability.

RESULTS

Nearly all participants perceived the medication dispensing device as very easy to use, very reliable and helpful in the management of their medications. Eighty-four percent of participants expressed a desire to use the machine in the future.

CONCLUSION

The technology-enhanced medication management device in this study is an acceptable tool for older adults to manage medication in collaboration with home care nurses. Improved usability and cost models for medication dispensers are areas for future research.

Strategies for reducing potentially avoidable hospitalizations for ambulatory care-sensitive conditions

PURPOSE

Hospitalizations for ambulatory care-sensitive conditions (ACSCs) are seen as potentially avoidable with optimal primary care. Little is known, however, about how primary care physicians rate these hospitalizations and whether and how they could be avoided. This study explores the complex causality of such hospitalizations from the perspective of primary care physicians.

METHODS

We conducted semistructured interviews with 12 primary care physicians from 10 primary care clinics in Germany regarding 104 hospitalizations of 81 patients with ACSCs at high risk of rehospitalization.

RESULTS

Participating physicians rated 43 (41%) of the 104 hospitalizations to be potentially avoidable. During the interviews the cause of hospitalization fell into 5 principal categories: system related (eg, unavailability of ambulatory services), physician related (eg, suboptimal monitoring), medical (eg, medication side effects), patient related (eg, delayed help-seeking), and social (eg, lack of social support). Subcategories frequently associated with physicians' rating of hospitalizations for ACSCs as potentially avoidable were after-hours absence of the treating physician, failure to use ambulatory services, suboptimal monitoring, patients' fearfulness, cultural background and insufficient language skills of patients, medication errors, medication nonadherence, and overprotective caregivers. Comorbidities and medical emergencies were frequent causes attributed to ACSC-based hospitalizations that were rated as being unavoidable.

CONCLUSIONS

Primary care physicians rated a significant proportion of hospitalizations for ACSCs to be potentially avoidable. Strategies to avoid these hospitalizations may target after-hours care, optimal use of ambulatory services, intensified monitoring of high-risk patients, and initiatives to improve patients' willingness and ability to seek timely help, as well as patients' medication adherence.

Insight into older peoples' healthcare experiences with managing COPD, asthma, and asthma-COPD overlap

OBJECTIVE

The aim of this study was to explore older peoples' experiences of asthma or COPD with reference to their journey in the healthcare system.

METHODS

We recruited older patients with a confirmed diagnosis of asthma or COPD and invited them to participate in a qualitative interview. Interviews were conducted with 21 participants. A line-by-line analysis of the interviews was performed and they were coded for common themes.

RESULTS

From the data, six main themes emerged, these were; "limits to being", "being with or without a diagnosis", "not being heard or recognized", "expectation, fears, and hopes", "to medicate or not: the underuse, abuse, and misuse", and "needing to understand more". The findings of these interviews provide an important understanding of the behaviors and healthcare needs of older people with asthma and COPD. Older patients' adherence patterns, desire for person-centeredness, and involvement in shared decisions as well as desire for increased objective assessment are described.

CONCLUSIONS

These findings provide an important understanding of the behaviors and healthcare needs of older people with asthma and COPD, an area that has not been well defined. The knowledge gained about older patients' desire for person--centeredness and involvement in shared decisions, as well as desire for increased objective assessment is essential in improving care.

Understanding older peoples' decisions about the use of sleeping medication: issues of control and autonomy

Poor sleep is known to impact on health and wellbeing in later life and has implications for the ability of older people to remain active during the day. Medical treatments for chronic poor sleep have primarily included the regular, long-term prescribing of hypnotics, which are known to impact on older people's health, cognitive function and quality of life. Therefore, recent policy and practice has focused on reducing such prescribing, on encouraging older people to stop taking long-term hypnotics and on finding alternative, non-pharmacological ways to manage poor sleep. However, little research has been undertaken to understand the perspectives of older people who choose not to seek professional help for their poor sleep, despite the potential impact of poor sleep on their health and ability to remain active. Through in-depth interviews with 62 older men and women living in their own homes in England, this article explores the factors that deter older people from seeking professional help for their poor sleep. We argue that these are located in their perceptions of the normativity of poor sleep in later life, their beliefs about prescription sleeping medications and their desire to maintain control and autonomy over their everyday and night lives.

Patient-tailored self-management intervention for older adults with hypertension in a nursing home

AIMS AND OBJECTIVES

This study was to evaluate the effects of a patient-tailored self-management intervention on (1) blood pressure control and (2) self-care behaviour, exercise self-efficacy and medication adherence among Korean older hypertensive patients in a nursing home.

BACKGROUND

  Little is known about whether a patient-tailored self-management for nursing home residents with hypertension is likely to advance the care of this growing population worldwide.

DESIGN

A non-equivalent comparison group design.

METHODS

Forty-seven patients (23 and 24 in the intervention and comparison groups, respectively) participated in the study. No one withdrew during the eight-week study period. Hypertensive patients in the intervention group received health education and tailored individual counselling for eight weeks to enhance the self-management.

RESULTS

The mean age of patients was 77·4 years. Patients were on hypertensive medications for 11·8 years; only 36 of them took medications without assistance. The baseline comparisons of the patients with and without 8-week intervention did not differ for clinical and demographic variables and outcome measures. Blood pressure decreased when comparing the baseline to eight weeks later from baseline; moreover, blood pressure was significantly reduced only in patients who received the intervention. Self-care behaviour and exercise self-efficacy significantly increased over time only in those who were in the intervention group. However, no significant difference was observed in medication adherence between the two groups.

CONCLUSIONS

Patient-tailored self-management intervention was a practical approach for decreasing blood pressure and increasing self-care behaviour in older hypertensive patients in a nursing home. Further studies are needed to validate these findings using a larger sample with long-term follow-up.

RELEVANCE TO CLINICAL PRACTICE

A patient-tailored intervention is feasible not only to empower nursing home residents with hypertension for their care, but also to offer a qualified training and guidelines to nursing home staffs, expanding their professional competence in clinical practice.

Adherence and medication management by the elderly

AIMS AND OBJECTIVES

The purpose of this study was to explore the strategies used for medication management by elderly who live at home.

BACKGROUND

Non-adherence to chronic medication is a common problem among the elderly with chronic conditions. Many studies have been developed, but it did not progress in solving this multidisciplinary health care problem. The causes of non-adherence by the elderly are multiple and complex.

DESIGN

Descriptive qualitative design.

METHODS

Data were collected by two focus groups. The content of discussion was analysed from verbatim transcript and identifying categories and sub-categories emerged, leading to the construction of a diagram analysis.

RESULTS

The finding indicated the strategies and the interpretation of people aged 65 or more and with chronic illness, managing their medication. Four content categories emerged: to live with drugs, taking medication, belief about drugs and relationship with health professionals.

CONCLUSION

The study enabled us to identify and understand, by giving a 'voice' to the elderly, that living with drugs is a dynamic and complex process and that taking medication is perceived by older people as a consequence of their ageing, which requires them to include that process in their lives as a habit implying changes in their daily routines. The elderly suggest that the relationship with health professionals is essential in medication management and they reported that the information given by the nurse during consultation is very important.

RELEVANCE TO CLINICAL PRACTICE

The relationship with nurses in particular is an important issue for the older people. Understanding the factors of adherence and helping people are important areas of research in nursing. The quality of this relationship may be the key to increasing adherence in this group of people.

Predictors of adherence to medication in older Korean patients with hypertension

BACKGROUND AND RESEARCH OBJECTIVES

Adherence to a medication regimen is a major factor in achieving adequate blood pressure control for hypertensive patients. However, older adults often report having missed doses, which they attribute to forgetfulness. The purpose of this study was to identify significant factors, including socioeconomic variables, hypertension history, and cognitive functions, contributing to medication adherence among older Korean adults with hypertension.

SUBJECTS AND METHOD

This study involved 241 older patients with hypertension from a community senior center during the period from 2008 to 2009. Data were collected through face to face interviews. The association of medication adherence with socioeconomic characteristics, hypertension-related history, knowledge, antihypertensive lifestyle, and memory was assessed by computing odds ratios in logistic regressions.

RESULTS AND CONCLUSIONS

Of the 241 patients, 44% were aged 75 or older, and 60% were male. The rate of non-adherence with antihypertensive medication was 41%. Metamemory, adherence to an antihypertensive lifestyle, and employment status, were associated with participants' adherence to antihypertensive medication in both univariate and multivariate analyses. Results suggest that memory functions are a key factor to medication adherence among the Korean elderly population. In contrast to younger adults, unintentional non-adherence appears to be a major issue for older adults to keep medicating. Interventions focusing on memory ability, such as strategies for recalling and placing cues, are needed for implementation in the population of older Korean patients with hypertension. Unemployed older people who have hypertensive lifestyles should also be considered a high-risk group for non-adherence to medication.

Adherence to adjuvant therapy in post-menopausal breast cancer patients: a review

This review aimed to address the concept of adherence to adjuvant therapy in post-menopausal women. Thirteen studies were included in the review. Study quality was assessed using Critical Appraisal Skills Programme and CONSORT tools. Adherence to adjuvant medication was assessed using a variety of methods. Estimates of adherence rates to adjuvant therapies indicated that of the post-menopausal women prescribed adjuvant therapy, between 15% and 55% were adherent to tamoxifen from 1 to 5 years of follow-up, albeit two studies proposed adherence rates greater than 85%; these data may be flawed due to the methods of data collection. Between 31% and 73% of women were adherent to anastrozole, letrozole or exemestane from 1 year of treatment. These estimates of adherence are based on a variety of reported records including self-report. Current evidence on the assessment of adherence to adjuvant therapies in post-menopausal women indicate that the adherence rates of medication maybe suboptimal and therefore therapeutic efficacy is questionable and may increase the risk of cancer recurrence and reduce disease survival rates. Concerted research is needed to investigate adherence rates, examine patient health beliefs in the medication management of post-menopausal breast cancer patients and also develop new measures to assess adherence with medication.

The challenges of oral agents as antineoplastic treatments

OBJECTIVES

Given the increasing use of oral antineoplastic agents in cancer management, patient adherence is critical to successful treatment outcomes. This article reviews the scope of the problem and issues of adherence to oral antineoplastic agents.

DATA SOURCES

Research-based and other articles, newsletters, and conference presentations.

CONCLUSION

Suboptimal adherence to oral antineoplastic agents is a significant clinical problem that may result in disease or treatment complications, adjustment in treatment regimen, disease progression, and premature death.

IMPLICATIONS FOR NURSING PRACTICE

Healthcare providers need to monitor and facilitate adherence by identifying barriers and implementing strategies to assure adherence, and therefore, improve clinical outcomes.

The effects of an integrated health education and exercise program in community-dwelling older adults with hypertension: a randomized controlled trial

OBJECTIVE

the aim of this study was to examine the effectiveness of HAHA (Healthy Aging and Happy Aging) program, which is an integrated health education and exercise program for community-dwelling older adults with hypertension.

METHODS

older adults with hypertension from one senior center were randomly allocated to experimental (n=18) or control group (n=22). Experimental group received health education, individual counseling and tailored exercise program for 12 weeks.

RESULTS

the mean ages were 71 years (experimental group) and 69 (control group). After the intervention, systolic blood pressure of experimental group was significantly decreased than that of control group. Scores of exercise self-efficacy, general health, vitality, social functioning, and mental health in SF-36 were statistically higher than those of control group.

CONCLUSION

the HAHA program was effective in control of systolic blood pressure and improving self-efficacy for exercise and health-related quality of life.

Prevalence of adherence to treatment in homebound elderly people in primary health care: a descriptive, cross-sectional, multicentre study

BACKGROUND

Adherence to the therapeutic plan is one of the most important health issues in terms of treatment efficacy, healthcare costs and patient safety. Unfortunately, homebound elderly patients are especially vulnerable to nonadherence because they have higher morbidity rates combined with cognitive and social problems that hinder their correct use of drugs. The level of therapeutic adherence in homebound elderly people has not been adequately studied.

OBJECTIVE

To estimate the prevalence of therapeutic adherence, using the Morisky-Green test, in homebound elderly patients taking polypharmacy (defined as use of four or more drugs), and to study the factors associated with adherence.

METHODS

This was a descriptive, cross-sectional, multicentre study. A total of 327 patients were selected by random start systematic sampling from the total number of homebound patients taking four or more drugs in Healthcare Area 4 of the Madrid Autonomous Region, Spain. Through an in-home survey of patients and their caregivers, information was gathered on sociodemographic data, co-morbidities, number of hospital admissions, responsibility for purchasing and preparation of the medication, level of cognitive impairment (Pfeiffer questionnaire), functional dependence in activities of daily living (Katz Index), knowledge of the disease (Batalla test), adherence to treatment (Morisky-Green test), visual and auditory perception, and caregiver burden (Zarit interview).

RESULTS

Of the homebound patients, 65.7% (95% CI 60.6, 70.9) had good adherence to treatment. The variables most negatively associated with therapeutic adherence, after adjustment for age, sex, number of drugs, knowledge of the disease, and cognitive function, were a large caregiver burden (odds ratio [OR] 3.09; 95% CI 1.75, 5.48) and impaired hearing (OR 2.00; 95% CI 1.17, 3.40). There was also a trend toward a positive association between nonadherence and patients aged <85 years (OR 1.57; 95% CI 0.93, 2.65) and patients who had nine or more drug prescriptions (OR 1.59; 95% CI 0.96, 2.65).

CONCLUSIONS

Poor therapeutic adherence in homebound elderly patients receiving polypharmacy is a serious problem affecting one of every three individuals concerned, and is directly related to caregiver burden, regardless of age, sex, cognitive status or number of drugs administered.

Healthcare utilisation and knowledge concerning prescribed drugs among older people

PURPOSE

The aim of this study was to explore healthcare consumption in relation to more versus less knowledge concerning prescribed drugs among older people with functional dependency and repeated healthcare contacts, and to explore the determinants of more versus less knowledge

METHODS

The sample comprised 63 persons (mean age 82.8 years). Data concerning use and knowledge about drugs, demographics, health complaints and self-reported diseases were collected from the baseline measure in an ongoing randomised controlled trial (RCT) and merged with data from two public registers about healthcare consumption 2 years prior to baseline measurement. Data were analysed descriptively and using regression analysis.

RESULTS

Fifty-two percent of the sample (n = 33) had less knowledge (defined as not knowing the indications for 50% or less of their prescribed drugs) and these had more acute hospitals stays (median 2 vs 0), more total hospital stays (median 2 vs 1) and more bed days in hospital (median 18 vs 3) than those with more knowledge. Bed days and visits to other outpatient staff groups were associated with less knowledge; visits to physicians were associated with more knowledge.

CONCLUSIONS

The healthcare consumption pattern of those with less knowledge differed from that of those with more knowledge in terms of more acute inpatient care. The results indicate that there is a need for the health system to create mechanisms to ensure that patients do not lose their knowledge about their drugs when admitted in an acute situation; there is also an apparent need for educational intervention with patients, starting at the time of admission.

Hypertension in the elderly

Hypertension is an important risk factor for cardiovascular morbidity and mortality, particularly in the elderly. Blood pressure elevation in the elderly is due to structural and functional changes that occur with aging. Treatment of hypertension reduces the risk of stroke, heart failure, myocardial infarction, all-cause mortality, cognitive impairment, and dementia in elderly patients with hypertension. A healthy lifestyle helps hypertension management, with benefits extending beyond lowering of blood pressure. Several classes of antihypertensive drugs are effective in preventing cardiovascular events. Treatment decisions should be guided by the presence of compelling indications such as diabetes or heart failure and by the tolerability of individual drugs or drug combinations in individual patients. The concomitant intake of certain medications that counter the effects of antihypertensive drugs and the frequent occurrence of orthostatic hypotension complicate treatment in older patients and drive down blood pressure control rates.
