Barriers and facilitators for medication adherence in stroke patients: a qualitative study conducted in French neurological rehabilitation units

Healthcare professional perspectives on medication challenges in the post-stroke patient

Background: Medications play an essential role in the management of patients who have experienced a stroke. Despite the recognised importance and widespread availability of secondary prevention guidelines, Irish research has shown a continuous failure to meet secondary prevention targets upon discharge. While complex interventions involving healthcare professionals (HCPs) such as Speech and Language Therapists (SLT), Occupational Therapists (OTs) and Pharmacists have been effective in combatting medication non-adherence, community multidisciplinary teams (MDTs) are not as well defined as in the acute setting, leading to wide variation in patient care. Therefore, this study aims to investigate the knowledge, attitudes, beliefs, and challenges faced by HCPs in the continuity of care post-discharge from a hospital stroke ward, and its impact on medication adherence. Methods: Semi-structured interviews and one focus group with HCPs were conducted, and data were analysed using Braun & Clarke's reflexive Thematic Analysis. Results: Fourteen HCPs (6 Pharmacy, 4 SLT, 4 OTs) participated in this study. Participants discussed their views under two main themes 1) continuity of care and 2) medication adherence. Sub-themes observed regarding continuity of care include management and organisation, interpersonal continuity, and informational continuity. Themes generated which impact medication adherence post-discharge include condition-related factors, medication-related factors, systemic and HCP factors, and patient-related factors. Discussion: Additional resources are required to bring community healthcare in line with the standard of acute care. Increased channels of communication must be established across contexts and disciplines, and may be achieved using interprofessional training through continuous professional development or third-level education, a more clearly defined community team structure, and discharge summaries completed to relevant quality standards. While suboptimal continuity of care was reported as contributing to medication non-adherence, HCPs also acknowledged the complexities of medication management post-stroke.

Why medicines are used differently from prescribed: a protocol for a prospective patient-oriented observational case study to investigate reasons for non-adherence in primary care

INTRODUCTION

Patients do not always tell the physician if they have used medicines differently from prescribed. The challenges that patients experience in medication self-management and adherence have been prioritised globally as among the most crucial factors influencing the effectiveness and safety of pharmacotherapies.

METHODS AND ANALYSIS

This study protocol presents a new patient-oriented method to investigate reasons for non-adherence using pharmacist-conducted medication reconciliation in a primary care clinic as data collection point. By interviewing, the pharmacist will learn how the patient has been taking the prescribed medicines and whether any non-prescription medicines and food supplements have been used for self-medication. The pharmacist will document the findings of the conversation to the electronic patient record in a structured format. The pharmacist will collect data related to the characteristics of the patients and outpatient clinics, patients' diseases and medications, and medication discrepancies. These data will be analysed for descriptive statistics to identify (1) the number of discrepancies between the physician's prescription orders and the patient's self-reported use of the medicines, (2) what kind of discrepancies there are, (3) which are high-risk medicines in terms of non-adherence and (4) why medicines were taken differently from prescribed; based on the results, (5) a preliminary conceptual model of patient-reported reasons for non-adherence will be constructed.

Medication non-adherence and associated factors among older adult stroke survivors in China

Aim: Medication non-adherence has remained a common and costly global health issue of growing importance among older adults. This study aims to determine the prevalence and associated factors related to medication non-adherence among older adult stroke survivors in China. Methods and results: In this cross-sectional study, a total of 402 older adult stroke survivors were recruited from three tertiary hospitals in China. The results of the survey showed that 61.4% exhibited medication non-adherence. The chances of medication non-adherence among older adult stroke survivors who had primary school or less educational levels were higher than those who had senior secondary and junior college educational levels [OR (95% CI) = 0.440(0.249, 0.778)] as well as those who had a bachelor's degree or above educational levels [OR (95%CI) = 0.367(0.202, 0.667)]. Moreover, the probability of medication non-adherence with 4-5 and ≥6 types of total prescription medications per day increased by 1.993 times [OR (95% CI) = 1.993(1.190, 3.339))] and 2.233 times [OR (95%CI) = 2.233(1.159, 4.300)], respectively, as compared to when there were ≤3 types. Furthermore, medication non-adherence decreased with the increase in health literacy scores (β = -0.641 (95% CI; (0.913, 0.965)) and BMQ specific-necessity scores (β = -0.131 (95% CI; 0.806, 0.995)). On the other hand, when the BMQ specific-concerns score increased by one unit, medication non-adherence increased by 11.1% [OR (95% CI) = 1.111(1.044, 1.182)]. Conclusion: The present study found that patient medication adherence among older adult stroke survivors in China is problematic and associated with educational levels, total prescribed drugs per day, beliefs about medication, and health literacy scores. This indicates that measures should be taken to enhance medication adherence among such higher-risk populations.

Multiprofessional intervention to improve adherence to medication in stroke patients: a study protocol for a randomised controlled trial (ADMED AVC study)

INTRODUCTION

Adherence to secondary preventive medications is often suboptimal in patients with stroke, exposing them to an increased risk of recurrent cerebral and/or cardiovascular events. Effective actions in the long term to improve adherence to medication are needed. The study will evaluate the efficacy of a collaborative multiprofessional patient-centred intervention conducted by a pharmacist on adherence to secondary preventive medication in stroke survivors.

METHODS AND ANALYSIS

This is a multicentre cluster-randomised controlled trial. Two groups of 91 patients (intervention vs standard care) will be recruited. The clinical pharmacist intervention targeting secondary preventive medication will consist of three parts over 1 year: (1) an individual semi-structured interview at hospital discharge; (2) follow-up telephone interviews at 3, 6 and 9 months after discharge; and (3) a final individual semi-structured interview 1 year after discharge. Information on patient follow-up will be shared with the general practitioner and the community pharmacist by sending a report of each interview. The primary outcome is adherence to medication during the 12 months after hospital discharge, assessed using a composite endpoint: the medication possession ratio associated with a self-administered questionnaire.

ETHICS AND DISSEMINATION

The local ethics committee, the national committee for use of personal data in medical research and the national data protection agency approved the study. The sponsor has no role in study design; collection, analysis and interpretation of data; or report writing.

DISCUSSION

This pharmacist-led educational programme has the potential to significantly improve adherence to medication in stroke survivors which could lead to a decrease in recurrent cerebral and/or cardiovascular events.

Impact of beliefs about medication on the relationship between trust in physician with medication adherence after stroke

OBJECTIVE

To investigate the relationship between medication adherence, trust in physician and beliefs about medication among stroke survivors. To determine whether beliefs about medication would mediate the relationship between trust in physician and medication adherence.

METHODS

A sample of 200 patients with a diagnosis of ischemic stroke or transient ischemic attack (TIA) completed a one-time survey, including the shortened Medication Adherence Report Scale (MARS-5), Beliefs about Medicines Questionnaire (BMQ), and Trust in Physician Scale (TIPS).

RESULTS

Our study found that medication adherence was associated with trust in physician (p = 0.019) and four factors of beliefs about medication (BMQ1-Necessity: p < 0.001; BMQ2-Concerns: p = 0.024; BMQ3-Overuse: p = 0.016; BMQ4-Harm: p < 0.001). Furthermore, we found monthly income of survivors moderated the relationship between trust in physician and medication adherence (p = 0.007, CI_(95%): [-0.822, -0.132]).

CONCLUSIONS

The beliefs about medication mediating the relationship between trust in physician and medication adherence were different based on the stroke survivors' income bracket.

PRACTICE IMPLICATIONS

Interventions being developed to improve medication adherence may benefit from improving stroke survivors' trust in physician and addressing their beliefs about medication. In addition, healthcare providers are advised to take monthly income into consideration to effectively address stroke survivors' concerns regarding prescribed medications to mitigate stroke recurrence.

Medication adherence early after stroke: using the Perceptions and Practicalities Framework to explore stroke survivors', informal carers' and nurses' experiences of barriers and solutions

Background

Secondary prevention medication after stroke reduces risk of recurrence, but adherence is often poor. Stroke survivors’, carers’ and nurses’ perspectives of early post-stroke medication adherence are unexplored.

Aim

The aim of this study was to explore stroke survivors’, carers’ and nurses’ views and experiences about adhering to medication early after post-stroke hospital discharge.

Methods

Qualitative individual and group interviews, utilising the Perceptions and Practicalities Framework, were employed. Nine people <2 months post-stroke, three carers and 15 nurses from one UK stroke unit participated. Interviews were digitally recorded, transcribed and thematically analysed.

Results

There were four main themes with two sub-themes. (1) Perceptions of medication taking after stroke. Factors affecting adherence included depression, imperceptible benefits and concerns about adverse effects. (2) Perceptions about those at higher risk of poor medication adherence. Nurses suggested that poor adherence might be more likely in those living alone or with previous non-adherence. (3) Practicalities of taking medication early after stroke; these included post-stroke disabilities, cognition, polypharmacy and lack of information. (4a) Practicalities of addressing poor medication adherence during the hospital stay. Solutions included multidisciplinary co-ordination, but nurses and stroke survivors described suboptimal use of opportunities to promote adherence. (4b) Practicalities of addressing poor medication adherence post-discharge. Solutions included modifications and support from carers, but stroke survivors reported difficulties in evolving systems for taking medications.

Conclusions

Stroke survivors and informal carers lack knowledge and support needed to manage medication early after discharge. Nurses’ opportunities to promote medication adherence are under-exploited. Medication adherence strategies to support stroke survivors early after discharge are needed.

Association Between Patient Activation and Medication Adherence in Patients With Stroke: A Cross-Sectional Study

Background: Medication adherence is key to secondary prevention in patients with stroke. Poor medication adherence can lead to recurrence, disability, or even death in stroke survivors. Patient activation is associated with increased healthy behaviors and improved clinical outcomes in many chronic diseases. However, the association between patient activation and medication adherence in patients with stroke remains unclear.

Objective: The study aimed to explore the influence of patient activation on the medication adherence of patients with stroke and to analyze the reasons for medication nonadherence.

Materials and Methods: A cross-sectional design with convenience sampling was used in this study. A total of 119 patients with stroke were recruited from a tertiary hospital in Guangzhou. A social-demographic and clinical data form, a self-developed medication adherence questionnaire, and the 13-item Patient Activation Measure (PAM-13) were used. Univariate analysis and multiple linear regression analysis with dummy variables were conducted to investigate the associations between medication adherence and patient activation. Data were analyzed with IBM® SPSS® version 25.0.

Results: The mean PAM-13 score in patients with stroke was 51.56 ± 12.58. A low level of patient activation was reported by up to 66.4% of the patients. The self-reported medication adherence questionnaire score was 5.59 ± 1.52. A low level of medication adherence was reported by up to 59.7% of the patients, while a moderate level was reported by 34.4%, and a high level was reported by only 5.9%. In the multiple stepwise regression analysis, patient activation was found to be an independent influencing factor of medication adherence in patients with stroke (p < 0.05).

Conclusion: Medication adherence was poor in patients in Guangzhou, China, following an ischemic stroke. Patient activation as the independent influencing factor identified in this study will support healthcare givers to develop the tailored intervention to improve medication adherence among patients with stroke in China.

Factors Contributing to Medication Adherence in Patients with a Chronic Condition: A Scoping Review of Qualitative Research

INTRODUCTION

Medication adherence continues to be a significant challenge in healthcare, and there is a shortage of effective interventions in this area. This scoping review studied the patient-related factors of medication adherence.

METHODS

We searched Medline Ovid, Scopus, and Cochrane Library from January 2009 to June 2021 to find the most recent original qualitative studies or systematic reviews that addressed the patient-related factors of medication adherence in treating chronic conditions. We used the PRISMA-ScR checklist to ensure the quality of the study.

RESULTS

The initial search revealed 4404 studies, of which we included 89 qualitative studies in the scoping review. We inductively organized the patient-related factors causing barriers, as well as the facilitators to medication adherence. The studies more often dealt with barriers than facilitators. We classified the factors as patient-specific, illness-specific, medication-related, healthcare and system-related, sociocultural, as well as logistical and financial factors. Information and knowledge of diseases and their treatment, communication, trust in patient-provider relationships, support, and adequate resources appeared to be the critical facilitators in medication adherence from the patient perspective.

DISCUSSION AND CONCLUSIONS

Patients are willing to discuss their concerns about medications. Better communication and better information on medicines appear to be among the critical factors for patients. The findings of this scoping review may help those who plan further interventions to improve medication adherence.

Association between depression and medication adherence in stroke survivor older adults

AIM

This study aimed to investigate the association between depression score and medication adherence in stroke survivor older adults.

METHODS

The participants were 102 stroke survivor older adults. The outcome was medication adherence during a 6-month follow-up. The independent variable was the depression score which was assessed by the Patient Health Questionnaire-9 (PHQ-9). The confounding factors included sociodemographic data, clinical characteristics, number of comorbidities, and number of medications. We analyzed the association between depression and medication adherence using multiple linear regression analyses.

RESULTS

The PHQ-9 score of stroke survivor older adults at the baseline was 1.11±2.03, and at the 6-month follow-up was increased to 5.06±3.91. The medication adherence mean score at the outcome was 4.15±1.83. After full adjustment, the PHQ-9 scores at baseline and 6-month follow-up were significantly associated with medication adherence (β = -.315, 95% CI = -.483 to -.086, p = 0.006 and β = -.270, 95% CI = -.238 to -.020, p = 0.021, respectively). Other variables that affect medication adherence during a 6-month follow-up included living with others and a lower number of medications.

CONCLUSION

This study revealed that lower depression scores were associated with high medication adherence in post-stroke older adults. Additionally, living with others and a lower number of medications were associated with medication adherence. Therefore, stroke survivor older adults should be assessed for depression and given medication, and education should be used to improve mediation adherence, especially for the ones who live alone and have polypharmacy to prevent recurrent stroke.

Facilitators and barriers to medication adherence among stroke survivors in India

Strict compliance with medication and life style modification are integral to secondary stroke prevention. This study was undertaken to find out medication adherence among stroke survivors and factors associated with it. Cross sectional survey among stroke survivors was conducted. Interview based self-reported medication adherence was defined as consumption at least >80% of their medications for last two weeks, based on last prescription. Structured interview using pretested interview schedule was done to collect other data. Sequential step wise logistic regression analysis was done to find out the facilitators and barriers to medication adherence. Two hundred and forty stroke survivors (mean age 58.64 ± 10.96 years; 25.4% females) with a mean post-stroke period of 6.65 ± 3.36 months were participated. Overall medication adherence was 43.8% (n = 105). Medication adherence was 34.3% (n = 134), 52.6% (n = 190) and 56.7% (n = 224) for antidiabetics, antihypertensives and statins respectively and was associated with risk factor control (Diabetes: Odds Ratio (OR) = 4.85; 95% Confidence Interval (CI) 2.12-11.08, Hypertension: OR = 3.42; 95% CI 1.83-6.4, Dyslipidaemia: OR = 3.88; 95% CI 1.96-4.04). Having daily routine (OR = 2.82; 95% CI 1.52-5.25), perceived need of medication (OR = 2.33; 95% CI 1.04-5.2) and perceived poor state of health (OR = 2.65; 95% CI 1.30-5.40) were facilitators. Memory issues (OR = 0.34; 95% CI 0.16-0.71), side effects (OR = 0.24; 95% CI 0.11-0.42) and financial constraints (OR = 0.46; 95% CI 0.24-0.91) were barriers to medication adherence. Establishing daily routines, periodic reminders, financial supports to buy medicines and patient education can enhance medication adherence to prevent future strokes.

Social Network Structure Is Related to Functional Improvement From Home-Based Telerehabilitation After Stroke

Objective: Telerehabilitation (TR) is now, in the context of COVID-19, more clinically relevant than ever as a major source of outpatient care. The social network of a patient is a critical yet understudied factor in the success of TR that may influence both engagement in therapy programs and post-stroke outcomes. We designed a 12-week home-based TR program for stroke patients and evaluated which social factors might be related to motor gains and reduced depressive symptoms. Methods: Stroke patients (n = 13) with arm motor deficits underwent supervised home-based TR for 12 weeks with routine assessments of motor function and mood. At the 6-week midpoint, we mapped each patient's personal social network and evaluated relationships between social network metrics and functional improvements from TR. Finally, we compared social networks of TR patients with a historical cohort of 176 stroke patients who did not receive any TR to identify social network differences. Results: Both network size and network density were related to walk time improvement (p = 0.025; p = 0.003). Social network density was related to arm motor gains (p = 0.003). Social network size was related to reduced depressive symptoms (p = 0.015). TR patient networks were larger (p = 0.012) and less dense (p = 0.046) than historical stroke control networks. Conclusions: Social network structure is positively related to improvement in motor status and mood from TR. TR patients had larger and more open social networks than stroke patients who did not receive TR. Understanding how social networks intersect with TR outcomes is crucial to maximize effects of virtual rehabilitation.

Stroke patients' support: evaluation of knowledge, practices and training needs of French community pharmacists

Background Stroke represents a major Public Health issue in industrialized countries because of its frequency and severity. In secondary stroke prevention, treatment efficacy is correlated to medication adherence. However, it remains suboptimal in stroke patients. Community pharmacists, in light of their positioning in the care pathway and proximity to patients, can play an essential role in patient support and improving treatment adherence. However, it is currently unknown whether pharmacists are ready to perform this task. Objective Evaluate knowledge, practices and training needs for community pharmacists in therapeutic stroke management to improve long term care for stroke patients. Setting Community pharmacies in the Rhone Alpes region (France). Method We conducted a cross sectional study via a standardized self-assessment questionnaire consisting of 40 questions divided into three parts. The latter was designed by a multidisciplinary team and distributed electronically to community pharmacists of the Rhône-Alpes region (France). Main outcome measure (a) global knowledge score on the pathology, risk factors and clinical care management, (b) description of the support practices for stroke patients, (c) training needs for pharmacists. Results The 104 participants presented a moderate level of knowledge (global score: 12/20 ± 3). Topics best mastered were: pathophysiology, target blood pressure and place of antiplatelets in the therapeutic strategy. Knowledge items that needed improvement were: warning signs correctly identified by 44% of participants, time delay for thrombolysis for which 14% answered correctly, target glycated hemoglobin levels were correct for 41%, and the 3 recommended antihypertensive drug classes were only identified by 5% of participants. Patient education received from pharmacists concerned dosage (89%), treatment adherence (88%), benefits (66%) and administration modalities of medicines (64%), management of risk factors (75% for diet, 73% for physical activity, 70% for smoking and 53% for alcohol). All pharmacists wanted additional training on risk factors and clinical management guidelines. Conclusion Based on this small study, the fragmented knowledge and varied practices promote the need for further training for pharmacists to optimize support of stroke patients. This study promotes the elaboration of training systems adapted to pharmacists' needs. This will help support the development of a targeted pharmaceutical care approach for stroke patients.

A Qualitative Study of Barriers and Facilitators to Adherence to Secondary Prevention Medications Among French Patients Suffering from Stroke and Transient Ischemic Attack

PURPOSE

Secondary prevention medications (SPM) reduce the risk of ischemic stroke (IS) and transient ischemic attack (TIA) recurrence. However, approximately one-third of patients are estimated to be non-adherent. This qualitative study aimed to explore barriers and facilitators to adherence to SPM after IS or TIA.

PATIENTS AND METHODS

Thirty-six face-to-face semi-structured interviews were conducted with 14 TIA patients and 22 IS patients who self-administered their treatment 12 months after IS/TIA. A thematic analysis was performed.

RESULTS

Major facilitators to good adherence to SPM were the fear of stroke recurrence and the high level of trust in the prescribing physician. Barriers included a perceived lack and/or inappropriate timing of information about SPM, practical difficulties of taking some SPM (eg, inadequate packaging) and of implementing routines into their daily life.

CONCLUSION

Information on SPM is inadequate in terms of quantity and timing both during the acute IS/TIA period and over the long term. Providing more tailor-made information at an opportune moment, in particular by promoting discussion with their general practitioner (GP) throughout the course of illness and recovery, is essential to ensure that patients are not left alone in the decision-making process regarding adherence to SPM.

A Medication Management Intervention for Patients and Families with SCI and ABI

The purpose of this study was to develop and test the efficacy of a pre-discharge, medication management intervention to improve perceived knowledge and perceived confidence for post-discharge medication management for rehabilitation patients with spinal cord injuries (SCIs) and families of patients with SCIs or acquired brain injuries (ABIs). We used a quasi-experimental, matched-pair design. Treatment participants (n = 112) completed the intervention with pre- and post-tests assessing perceived knowledge and perceived confidence for post-discharge medication management. Control participants (n = 95) enrolled at 60-days post-discharge. All participants (N = 207) completed measures on perceived knowledge, perceived confidence, and medication management by phone at 60-days post-discharge. The intervention significantly increased treatment participants' perceived knowledge and perceived confidence from pre- to post-test. Sex, injury severity, and income were associated with primary outcomes. Treatment participants used more tools for medication management post-discharge. Our findings suggest that patients and family members may benefit from pre-discharge medication management interventions.

Medication-taking after stroke: a qualitative meta-synthesis of the perspectives of stroke survivors, informal carers and health professionals

BACKGROUND

Lifelong secondary prevention medication is recommended after stroke or transient ischaemic attack. However, poor medication adherence and persistence, which lead to suboptimal health outcomes, are common, but the reasons for this are not well understood, mainly because there have been few studies reporting adherence barriers in stroke survivors.

OBJECTIVE

The aim of this review was to undertake a meta-synthesis of qualitative studies of medication-taking after stroke. Outcomes of interest were: lived experiences, views and beliefs, and strategies and solutions used by community-dwelling stroke and transient ischaemic attack survivors, informal carers and health care professionals in relation to medication-taking.

METHOD

The review protocol was registered on PROSPERO (CRD42018086792). A search of online bibliographic databases was performed using key search terms of stroke, persistence, adherence and medication for years 1980-2018. Citation tracking was also carried out. Studies using qualitative or mixed methods were included. Systematic data extraction and synthesis were conducted using a meta-ethnographic approach.

RESULTS

Twelve studies were eligible for inclusion, with a total of 412 participants, two-thirds of whom were stroke survivors, ranging from 1 month to over 20 years post-stroke. Third-order themes identified were 'Medicines Work'-Information Work; Health Care Work; Carer Work; Emotional Work; Practical Work and an underpinning theme of Trust. However, many studies had significant methodological weaknesses.

CONCLUSIONS

This synthesis suggests that the burden of 'medicines work' after stroke is substantial and multifaceted. Its successful undertaking depends on mutual trust between stroke survivors, carers and health care professionals and trust in the benefits of medicines themselves.

Factors affecting adherence to rehabilitation in Iranian stroke patients: A qualitative study

Adherence to rehabilitation has significant effects on patient outcomes. This study aimed to explore factors affecting adherence to rehabilitation in Iranian stroke patients. This is a descriptive, qualitative study. This study was conducted in 2018. Participants were stroke patients, family members, and rehabilitation team members-20 in total. They were purposively recruited from Rofaideh inpatient rehabilitation center in Tehran, and the outpatient physiotherapy center of Poursina hospital in Rasht. Data collection was performed through semistructured interviews and was continued up to data saturation. Data were analyzed by content analysis technique. Factors affecting adherence to rehabilitation in stroke patients were categorized into four main categories, namely patients-related, rehabilitation team, rehabilitation systems, and insurance and social support systems factors. Health care providers can promote patients' adherence to rehabilitation, involvement in the process of treatment, and their quality of life through broadening patients' knowledge about rehabilitation effectiveness, strengthening communication with health care providers, and adequate insurance and social support.

Validation of the 5-Item Medication Adherence Report Scale in Older Stroke Patients in Iran

BACKGROUND

There is a lack of feasible and validated measures to self-assess medication adherence for older patients with stroke. In addition, the potential determinants of medication adherence for older patients with stroke remain unclear.

OBJECTIVES

The aims of this study were to (1) examine the psychometric properties of a 5-item questionnaire on medication adherence, specifically the 5-item Medication Adherence Report Scale (MARS-5), and (2) explore the determinants of medication adherence.

METHODS

Stroke patients older than 65 years (N = 523) filled out the MARS-5 and the Hospital Anxiety and Depression Scale. The medication possession rate (MPR) was calculated to measure the objective medication adherence. Several clinical characteristics (stroke types, blood pressure, comorbidity, HbA1c, quantity of prescribed drugs, fasting blood glucose, and total cholesterol) and background information were collected. We used Rasch analysis with a differential item functioning test to examine psychometric properties.

RESULTS

All 5 items in the MARS-5 fit in the same construct (ie, medication adherence), no differential item functioning items were displayed in the MARS-5 across gender, and the MARS-5 total score was strongly correlated with the MPR (r = 0.7). Multiple regression models showed that the MARS-5 and the MPR shared several similar determinants. In addition, the variance of the MARS-5 (R = 0.567) was more than that of the MPR (R = 0.300).

CONCLUSIONS

The MARS-5 is a feasible and valid self-assessed medication adherence for older patients with stroke. In addition, several determinants were found to be related to medication adherence for older patients with stroke. Healthcare providers may want to take heed of these determinants to improve medication adherence for this population.

Secondary Prevention Three and Six Years after Stroke Using the French National Insurance Healthcare System Database

BACKGROUND

Secondary prevention is inadequate in the first 2 years after stroke but what happens after that is less documented. The aim of this study was to assess the use and the adherence to preventive drugs 3 and 6 years after experiencing a transient ischemic attack (TIA) or an ischemic stroke (IS).

METHODS

The population study was from the AVC69 cohort (IS or TIA admitted in an emergency or stroke unit in the Rhône area, France, for an IS or a TIA during a 7-month period). Medication use was defined as ≥1 purchase during the studied year and adherence as Continuous Measure of Medication Acquisition ≥0.8 using the French medical insurance health care funding database.

RESULTS

The study population consisted of 210 patients at 3 years and 163 patients at 6 years. Medication use at 3 and 6 years was, respectively, 80.9 and 79.8% for antithrombotics, 69.1 and 66.3% for antihypertensives, 60.5 and 55.2% for statins and 48.6 and 46.6% for optimal treatment defined as the treatment achieved by the use of the 3 drugs. Adherence to each class was good at 3 years and tends to decrease at 6 years.

CONCLUSIONS

More than one patient out of 2 do not use the optimal preventive treatment.

Evaluating practical support stroke survivors get with medicines and unmet needs in primary care: a survey

OBJECTIVES

To design a questionnaire and use it to explore unmet needs with practical aspects of medicine taking after stroke, predictors of medicine taking and to estimate the proportion of survivors who get support with daily medication taking.

DESIGN

Four workshops with stroke survivors and caregivers to design the questionnaire.A cross-sectional postal questionnaire in primary care.

SETTING

18 general practitioner practices in the East of England and London. Questionnaires posted between September 2016 and February 2017.

PARTICIPANTS

1687 stroke survivors living in the community outside institutional long-term care.

PRIMARY OUTCOME MEASURES

The proportion of community stroke survivors receiving support from caregivers for practical aspects of medicine taking; the proportion with unmet needs in this respect; the predictors of experiencing unmet needs and missing taking medications.

RESULTS

A five-item questionnaire was developed to cover the different aspects of medicine taking. 596/1687 (35%) questionnaires were returned. 56% reported getting help in at least one aspect of taking medication and 11% needing more help. 35% reported missing taking their medicines. Unmet needs were associated with receiving help with medications (OR 5.9, P<0.001), being on a higher number of medications (OR 1.2, P<0.001) and being dependent for activities of daily living (OR 4.9, P=0.001). Missing medication was associated with having unmet needs (OR 5.3, P<0.001), receiving help with medications (OR 2.1, P<0.001), being on a higher number of medicines (OR 1.1, P=0.008) and being older than 70 years (OR 0.6, P=0.006).

CONCLUSIONS

More than half of patients who replied needed help with taking medication, and 1 in 10 had unmet needs in this regard. Stroke survivors dependent on others have more unmet needs, are more likely to miss medicines and might benefit from focused clinical and research attention. Novel primary care interventions focusing on the practicalities of taking medicines are warranted.

Psychological Determinants of Medication Adherence in Stroke Survivors: a Systematic Review of Observational Studies

BACKGROUND

Medications targeting stroke risk factors have shown good efficacy, yet adherence is suboptimal. To improve adherence, its determinants must be understood. To date, no systematic review has mapped identified determinants into the Theoretical Domains Framework (TDF) in order to establish a more complete understanding of medication adherence.

PURPOSE

The aim of this study was to identify psychological determinants that most influence stroke survivors' medication adherence.

METHODS

In line with the prospectively registered protocol (PROSPERO CRD42015016222), five electronic databases were searched (1953-2015). Hand searches of included full text references were undertaken. Two reviewers conducted screening, data extraction and quality assessment. Determinants were mapped into the TDF.

RESULTS

Of 32,825 articles, 12 fulfilled selection criteria (N = 43,984 stroke survivors). Tested determinants mapped into 8/14 TDF domains. Studies were too heterogeneous for meta-analysis. Three TDF domains appeared most influential. Negative emotions ('Emotions' domain) such as anxiety and concerns about medications ('Beliefs about Consequences' domain) were associated with reduced adherence. Increased adherence was associated with better knowledge of medications ('Knowledge' domain) and stronger beliefs about medication necessity ('Beliefs about Consequences' domain). Study quality varied, often lacking information on sample size calculations.

CONCLUSIONS

This review provides foundations for evidence-based intervention design by establishing psychological determinants most influential in stroke survivors' medication adherence. Six TDF domains do not appear to have been tested, possibly representing gaps in research design. Future research should standardise and clearly report determinant and medication adherence measurement to facilitate meta-analysis. The range of determinants explored should be broadened to enable more complete understanding of stroke survivors' medication adherence.

Barriers and facilitators to adherence to secondary stroke prevention medications after stroke: analysis of survivors and caregivers views from an online stroke forum

OBJECTIVE

To identify barriers and facilitators of medication adherence in patients with stroke along with their caregivers.

DESIGN

Qualitative thematic analysis of posts about secondary prevention medications, informed by Perceptions and Practicalities Approach.

SETTING

Posts written by the UK stroke survivors and their family members taking part in the online forum of the Stroke Association, between 2004 and 2011.

PARTICIPANTS

84 participants: 49 stroke survivors, 33 caregivers, 2 not stated, identified using the keywords 'taking medication', 'pills', 'size', 'side-effects', 'routine', 'blister' as well as secondary prevention medication terms.

RESULTS

Perceptions reducing the motivation to adhere included dealing with medication side effects, questioning doctors' prescribing practices and negative publicity about medications, especially in regard to statins. Caregivers faced difficulties with ensuring medications were taken while respecting the patient's decisions not to take tablets. They struggled in their role as advocates of patient's needs with healthcare professionals. Not experiencing side effects, attributing importance to medications, positive personal experiences of taking tablets and obtaining modification of treatment to manage side effects were facilitators of adherence. Key practical barriers included difficulties with swallowing tablets, dealing with the burden of treatment and drug cost. Using medication storage devices, following routines and getting help with medications from caregivers were important facilitators of adherence.

CONCLUSIONS

An online stroke forum is a novel and valuable resource to investigate use of secondary prevention medications. Analysis of this forum highlighted significant barriers and facilitators of medication adherence faced by stroke survivors and their caregivers. Addressing perceptual and practical barriers highlighted here can inform the development of future interventions aimed at improving adherence to secondary prevention medication after stroke.

Barriers to medication adherence for the secondary prevention of stroke: a qualitative interview study in primary care

Background

Medications are highly effective at reducing risk of recurrent stroke, but success is influenced by adherence to treatment. Among survivors of stroke and transient ischaemic attack (TIA), adherence to medication is known to be suboptimal.

Aim

To identify and report barriers to medication adherence for the secondary prevention of stroke/TIA.

Design and setting

A qualitative interview study was conducted within general practice surgeries in the East of England, UK.

Method

Patients were approached by letter and invited to take part in a qualitative research study. Semi-structured interviews were undertaken with survivors of stroke, caregivers, and GPs to explore their perspectives and views around secondary prevention and perceived barriers to medication adherence. Key themes were identified using a grounded theory approach. Verbatim quotes describing the themes are presented here.

Results

In total, 28 survivors of stroke, including 14 accompanying caregivers and five GPs, were interviewed. Two key themes were identified. Patient level barriers included ability to self-care, the importance people attach to a stroke event, and knowledge of stroke and medication. Medication level barriers included beliefs about medication and beliefs about how pills work, medication routines, changing medications, and regimen complexity and burden of treatment.

Conclusion

Patients who have had a stroke are faced with multiple barriers to taking secondary prevention medications in UK general practice. This research suggests that a collaborative approach between caregivers, survivors, and healthcare professionals is needed to address these barriers and facilitate medication-taking behaviour.

Predictive factors of non-adherence to secondary preventative medication after stroke or transient ischaemic attack: A systematic review and meta-analyses

Purpose

Non-adherence to secondary preventative medications after stroke is relatively common and associated with poorer outcomes. Non-adherence can be due to a number of patient, disease, medication or institutional factors. The aim of this review was to identify factors associated with non-adherence after stroke.

Method

We performed a systematic review and meta-analysis of studies reporting factors associated with medication adherence after stroke. We searched MEDLINE, EMBASE, CINAHL, PsycINFO, CENTRAL and Web of Knowledge. We followed PRISMA guidance. We assessed risk of bias of included studies using a pre-specified tool based on Cochrane guidance and the Newcastle–Ottawa scales. Where data allowed, we evaluated summary prevalence of non-adherence and association of factors commonly reported with medication adherence in included studies using random-effects model meta-analysis.

Findings

From 12,237 titles, we included 29 studies in our review. These included 69,137 patients. The majority of included studies (27/29) were considered to be at high risk of bias mainly due to performance bias. Non-adherence rate to secondary preventative medication reported by included studies was 30.9% (95% CI 26.8%–35.3%). Although many factors were reported as related to adherence in individual studies, on meta-analysis, absent history of atrial fibrillation (OR 1.02, 95% CI 0.72–1.5), disability (OR 1.27, 95% CI 0.93–1.72), polypharmacy (OR 1.29, 95% CI 0.9–1.9) and age (OR 1.04, 95% CI 0.96–1.14) were not associated with adherence.

Discussion

This review identified many factors related to adherence to preventative medications after stroke of which many are modifiable. Commonly reported factors included concerns about treatment, lack of support with medication intake, polypharmacy, increased disability and having more severe stroke.

Conclusion

Understanding factors associated with medication taking could inform strategies to improve adherence. Further research should assess whether interventions to promote adherence also improve outcomes.
