Exploring stroke survivors' self-efficacy in understanding and taking medication and determining associated factors: a cross-sectional study in a neurology clinic in Malaysia

Construct validity, responsiveness, minimal detectable change, and minimal clinically important difference of the stroke self-efficacy questionnaire in individuals receiving stroke rehabilitation

PURPOSE

To assess the clinimetric properties of the Stroke Self-Efficacy Questionnaire (SSEQ) and estimate the minimal detectable change (MDC) and minimal clinically important difference (MCID) from the database of our randomized controlled trials (RCT) of individuals receiving stroke rehabilitation.

METHODS

We retrieved the pre- and post-intervention scores of the SSEQ and Stroke Impact Scale (SIS) from 80 stroke survivors. The analysis of clinimetric properties was performed using: (1) confirmatory factor analysis and item response theory modeling (IRT) for construct validity; (2) standardized response mean and Glass's delta for responsiveness; (3) MDC based on the standard deviation (SD) or standard error of measurement (SEM) of the SSEQ change scores; (4) MCID determined by the external anchor-SIS; (5) conditional MDC (cMDC) derived from the IRT analysis.

RESULTS

There was a bi-factorial construct with excellent model-data fit and marked responsiveness. The MDC determined by the SD and SEM were 1.5 and 3.0, respectively, and the MCIDs were 3.3 and 3.7.

CONCLUSIONS

This study confirmed that SSEQ is a valid and reliable assessment tool for patients receiving stroke rehabilitation. We also provided practical threshold values, especially demonstrating the benefit of using individualized cMDC, to help clinicians better interpret the change in the SSEQ scores.

Health literacy is associated with less depression symptoms, higher perceived recovery, higher perceived participation, and walking ability one year after stroke - a cross-sectional study

INTRODUCTION

Life after stroke may entail several lifestyle changes and new routines. Hence, it is imperative for people with stroke to understand and make use of health information, i.e. to have sufficient health literacy. This study aimed to explore health literacy and its associations with outcomes at 12-months post-discharge regarding depression symptoms, walking ability, perceived stroke recovery, and perceived participation in people with stroke.

METHODS

This was a cross-sectional study of a Swedish cohort. Data were collected at 12 months post-discharge using European Health Literacy Survey Questionnaire, the Hospital Anxiety and Depression Scale, the 10-m walk test, and the Stroke Impact Scale 3.0. Each outcome was then dichotomized into favorable versus unfavorable outcome. Logistic regression was performed to assess the association between health literacy and favorable outcomes.

RESULTS

The participants, n = 108, were on average 72 years old, 60% had mild disability, 48% had a university/college degree, and 64% were men. At 12 months post-discharge, 9% of the participants had inadequate health literacy, 29% problematic health literacy, and 62% sufficient health literacy. Higher levels of health literacy were significantly associated with favorable outcomes relating to depression symptoms, walking ability, perceived stroke recovery, and perceived participation in models adjusted for age, sex, and education level.

CONCLUSION

The association between health literacy and mental, physical, and social functioning 12-months post-discharge suggests that health literacy is an important factor to consider in post-stroke rehabilitation. Longitudinal studies of health literacy in people with stroke are warranted to explore the underlying reasons for these associations.

Medication self-management interventions for persons with stroke: A scoping review

The use of multiple medications is common following a stroke for secondary prevention and management of co-occurring chronic conditions. Given the use of multiple medications post-stroke, optimizing medication self-management for this population is important. The objective of this scoping review was to identify and summarize what has been reported in the literature on interventions related to medication self-management for adults (aged 18+) with stroke. Electronic databases (Ovid Medline, Ovid Embase, EBSCO CINAHL, Ovid PsycINFO, Web of Science) and grey literature were searched to identify relevant articles. For inclusion, articles were required to include an adult population with stroke undergoing an intervention aimed at modifying or improving medication management that incorporated a component of self-management. Two independent reviewers screened the articles for inclusion. Data were extracted and summarized using descriptive content analysis. Of the 56 articles that met the inclusion criteria, the focus of most interventions was on improvement of secondary stroke prevention through risk factor management and lifestyle modifications. The majority of studies included medication self-management as a component of a broader intervention. Most interventions used both face-to-face interactions and technology for delivery. Behavioural outcomes, specifically medication adherence, were the most commonly targeted outcomes across the interventions. However, the majority of interventions did not specifically or holistically target medication self-management. There is an opportunity to better support medication self-management post-stroke by ensuring interventions are delivered across sectors or in the community, developing an understanding of the optimal frequency and duration of delivery, and qualitatively exploring experiences with the interventions to ensure ongoing improvement.

Relationship between self-efficacy and adherence to self-management and medication among patients with chronic diseases in China: A multicentre cross-sectional study

PURPOSE

This study aimed to explore the effects of self-efficacy on adherence to self-management and medication among patients with chronic diseases in China.

METHODS

A cross-sectional survey of 2047 patients with chronic diseases in 120 cities across China was conducted between May and September 2021 using a multi-stage sampling method. Self-efficacy was measured using the New General Self-Efficacy Scale. The adherence to self-management was measured using the item response theory based self-management adherence scale, and the medication adherence was assessed using the Medication Adherence Scale for the Chronically Ill. The adherence to self-management and medication were evaluated by linear regression and logistic regression models, respectively.

RESULTS

After adjusting for all covariates, self-efficacy was significantly associated with adherence to self-management (β =0.207, 95% CI =0.064-0.350, P = 0.005), but not with medication adherence (for[middle/low]: OR = 1.119, 95% CI =0.828-1.511, P = 0.47; for[high/low]: OR = 1.281, 95% CI =0.935-1.754, P = 0.12). In subgroup analysis, self-efficacy positively correlated with adherence to self-management in patients with multiple chronic diseases (β =0.286, 95% CI =0.037-0.535, P = 0.03), but not in those with only one chronic disease (P = 0.12). Self-efficacy was not significantly associated with medication adherence in any of the subgroups.

CONCLUSION

Self-efficacy was positively associated with adherence to self-management in patients with chronic diseases, but not with medication adherence. Enhanced health education in patients with one chronic disease alone may have an association with better adherence to self-management and medication in daily life.

Medication adherence status among patients with neurological conditions and its association with quality of life

Background/Aim

Medication non-adherence may cause significant morbidity and mortality in patients with chronic diseases and may increase the economic burden on the healthcare system. The prevalence of neurological disorders is increasing in Malaysia; however, comprehensive data on medication adherence among Malaysian patients with these disorders is limited. This study was conducted to determine the association of medication non-adherence with quality of life in patients with neurological problems.

Methods

A cross-sectional survey was performed in 370 patients diagnosed with epilepsy, Parkinson's disease, stroke and Alzheimer's disease at Neurology clinic. Patients aged 18 years or older, without documented physical or psychiatric illness such as schizophrenia and major depression, were included. Patient-administered questionnaires, such as the Malaysian Medication Adherence Scale and Medication Possession Ratio were used to determine medication adherence. An established EQ-5D-3L questionnaire was used to determine quality of life. Data were analysed using descriptive and inferential analysis.

Results

The overall prevalence of medication non-adherence among patients with neurological disorders was 59.2%. Among these neuromedical diseases, 69.2% (n = 9/13) of Alzheimer's disease, 66.7% (n = 98/147) of epilepsy, 62.1% (n = 36/58) of Parkinson's disease and 48.7% (n = 74/152) of stroke patients were found non-adherent. There was a significant difference in EQ-5D index scores (p = 0.041) between adherent and non-adherent patients.

Conclusion

A high prevalence of medication non-adherence was found among patients with neurological disorders. The rate of non-adherence varied among different neurological conditions. There was a significant difference in quality of life between adherent and non-adherent patients.

Knowledge of stroke and medication adherence among patients with recurrent stroke or transient ischemic attack in Indonesia: a multi-center, cross-sectional study

BackgroundThere is a limited data in Indonesia regarding the stroke knowledge and medication adherence among stroke survivors.ObjectiveTo assess the level of stroke knowledge and medication adherence along with their relationship among stroke survivors.SettingTwo tertiary-care hospitals in Surabaya, East Java, Indonesia.MethodsA prospective, cross-sectional study was conducted among 215 stroke survivors. Stroke Knowledge Test and the Morisky Green Levine Adherence Scale questionnaires were used to evaluate stroke knowledge and medication adherence, respectively. Binary logistic regression was performed to assess the rela tionship between stroke knowledge and medication adherence. Main outcome measuresRelationship between stroke knowledge and medication adherence.ResultsA total of 215 patients with mean age of 56.34 ± 8.69 years were recruited into this study. Mean Stroke Knowledge Test score was 7.89 ± 3.38 with 76.7% had low level of stroke knowledge. Mean Morisky Green Levine Adherence Scale was 3.05 ± 1.11 with 52.1% had low to medium medication adherence. Education and duration of stroke correlated with stroke knowledge level (Spearman's correlation coefficient: 0.307, p = 0.001 and 0.128, p = 0.041, respectively). Age and disability correlated with medication adherence (Spearman's correlation coefficient: 0.169; p = 0.013 and 0.171; p = 0.012), respectively. After adjustment for covariates, stroke knowledge level was independently associated with medication adherence (adjusted OR: 4.37, 95% CI 2.00-9.53; p < 0.001).ConclusionStroke knowledge was low among Indonesian stroke survivors and independently related to medication adherence. Attempts should be made to increase stroke knowledge which may improve medication adherence among stroke survivors.

An Evaluation of the Video Narrative Technique on the Self-Efficacy of Medication Understanding and Use Among Post-Stroke Patients: A Randomized-Controlled Trial

INTRODUCTION

Self-efficacy is positively associated with medication understanding and use self-efficacy (MUSE) among post-stroke patients. It is also closely related to knowledge, belief, and perception, which vary among people from different socioeconomic backgrounds and cultures. As interventions using video and peer stories have emerged to be successful on behavior modification, this study aimed to explore the effectiveness of video narratives incorporated with Health Belief constructs on MUSE and its associated factors among patients with stroke at a local setting.

METHODS

A randomized controlled trial (RCT) for 12 months was carried out on patients diagnosed with stroke at Hospital Kuala Lumpur, Malaysia. The RCT recruited up to 216 eligible patients who were requested to return for two more follow-ups within six months. Consented patients were randomized to either standard care or intervention with video narratives. The control of potential confounding factors was ensured, as well as unbiased treatment review with prescribed medications, only obtained onsite.

RESULTS AND DISCUSSION

A repeated measure of MUSE mean score differences at T0 (baseline), T2 (6th month) and T4 (12th month) for antithrombotic, antihypertensive, and all medication categories indicated significant within and between groups differences in the intervention group (p<0.05). Moreover, this impact was reflected upon continuous blood pressure (BP) monitoring compared to the control group (F (1214) =5.23, p=0.023, ƞ2=0.024). Though BP measure differences were non-significant between the groups (p=0.552), repeated measure analysis displayed significant mean differences between intervention and control group on BP control over time (F (1.344, 287.55) =8.54, P<0.001, ƞ2=0.038). Similarly, the intervention's positive impact was also present with similar trends for knowledge, illness perception, and the belief about medicine. Though significant differences (p<0.05) of all outcome measures gradually decreased between T2 and T4 in the intervention group; nevertheless, these positive findings confirmed that personalized video narratives were able to motivate and influence MUSE and its associated factors among post-stroke patients. The significant improvement in medication-taking self-efficacy and the sustenance of BP monitoring habits among patients in the intervention group strengthened our conceptual framework's practicality.
