Factors associated with medication refill adherence in cardiovascular-related diseases: a focus on health literacy

Considering health literacy in communication about medications between nurses and patients with heart failure: A cross sectional observational study

OBJECTIVES

To explore the content, style, and initiation of medication-related discussions between nurses and patients to understand how nurses support patients with heart failure, especially those with inadequate health literacy.

METHODS

A cross-sectional design was conducted to observe medication-related conversations between nurses and patients with heart failure in four Dutch outpatient clinics. Conversations were audio-recorded and analyzed using MEDICODE, focusing on content, communication style (monologue or a dialogue), and initiation of the content themes. Health literacy was assessed using the NVS-D and the SBSQ. Results between health literacy groups were compared with descriptive analyses.

RESULTS

A total of 56 patients and 14 nurses participated in the study. Patients classified by one or both of the instruments as having inadequate health literacy (n = 33; 59 %) were generally older, had lower educational levels, and were more often accompanied by informal caregivers. Key themes discussed in the medication-related conversations included how the medication was identified ('medication designation), its dosage and instruction, main effects, side effects, attitude or emotions and other ('various') themes. The 'medication designation' theme was significantly more frequently discussed in the group with adequate health literacy, whereas 'attitude or emotions' and 'various themes' were more commonly discussed among those with inadequate health literacy. Most conversations were nurse-initiated and tended to be monologues, with nurses mainly serving as information providers.

CONCLUSIONS

Nurses primarily initiated and dominated medication-related discussions with a focus on factual aspects of medication, while patients initiated more discussions about their concerns regarding medication. While there was overlap in the topics discussed, notable differences emerged between patients with adequate and inadequate health literacy.

PRACTICE IMPLICATIONS

Improving communication strategies, such as structuring conversations and adopting dialogic approaches may improve patients' engagement and understanding of medication use, leading to more effective management of their condition, particularly benefiting patients with lower health literacy.

An interactive visualization dashboard for predicting the effect of sacubitril/valsartan initiation in patients with heart failure

BACKGROUND

Sacubitril/valsartan (S/V) reduces mortality and hospitalization rates in patients with heart failure with reduced ejection fraction (HFrEF), but low adherence remains a challenge. Early initiation of S/V is recommended, yet no practical tool currently exists to effectively communicate its benefits to outpatients or assess patient stability before S/V initiation during hospitalization.

METHODS

We collected data retrospectively from 527 HFrEF patients who started S/V between March 2017 and January 2020 at the National Taiwan University Hospital, with follow-up through September 2022. A modern stepwise variable selection approach was applied to fit the optimal Cox's proportional-hazards model to address nonlinear covariate effects and potential multicollinearity. Penalized smoothing splines were used to visualize nonlinear effects and identify cutoff values for continuous covariates. The model was then integrated into an interactive Streamlit dashboard for real-time simulation and risk prediction based on patient-specific covariates.

RESULTS

We identified 20 key variables - 12 associated with increased risk and 8 conferring protective effects. Some variables presented actionable cutoff values. The predictive model helped estimate individualized hazard ratios and covariate-adjusted survival curves, which serve as both a patient engagement platform in outpatient settings and a practical tool for physicians to assess inpatient stability before initiating S/V.

CONCLUSION

Our interactive visualization dashboard can potentially improve medication adherence and clinical outcomes by involving patients in their treatment journey and facilitating more informed decision-making. A pragmatic clinical trial is currently underway to further evaluate the dashboard's clinical utility and effectiveness in both outpatient and inpatient environments.

Association between guideline-directed medical therapy and reintervention risk following peripheral vascular interventions in patients with peripheral artery disease

INTRODUCTION

Reintervention following peripheral vascular intervention (PVI) for peripheral artery disease (PAD) is common. Guideline-directed medical therapy (GDMT) is recommended post-PVI, yet its association with reintervention outcomes remains unclear.

METHODS

We analyzed Vascular Quality Initiative registry data linked with Medicare outcome for patients undergoing PVI for PAD (2017-2018). GDMT was defined as the receipt of statin, antiplatelet, and angiotensin-converting enzyme or angiotensin receptor blocker (ACE/ARB) therapy if hypertensive at discharge. Competing risk analyses and conditional risk models assessed the reintervention outcome, and the recurrent reintervention outcomes within 2 years, by GDMT receipt, compliance with each GDMT element, the number of elements received, and GDMT rate across sites and operators in a 1:1 propensity score-matched cohort.

RESULTS

We included 13,244 patients (mean age 72.0 ± 9.9, women 41.0%). The reintervention outcome did not differ by GDMT receipt (cumulative incidence: 43.0% [95% CI 41.0-44.9%] in no GDMT vs 41.2% [95% CI 39.4- 43.0%] in GDMT; subhazard ratio (sHR): 1.03 [95% CI 0.97-1.10]), compliance with GDMT elements, the number of elements received, or site and operator GDMT rates (sHR per 10% increase: 1.00 [95% CI 0.98-1.03] and 1.00 [95% CI 0.98-1.02]) (all p > 0.05). However, a higher operator GDMT rate reduced the recurrent reintervention risk (HR: 0.98 [95% CI 0.97-1.00], p = 0.026).

CONCLUSION

Around 40% of patients undergoing a PVI experience reintervention within 2 years, but the outcome was not reduced with GDMT receipt, and higher GDMT rates by site and operators were not associated with reintervention risk. Future studies should focus on medication adherence, refills, and more granular GDMT data for PAD care surveillance postrevascularization.

Cognitive impairment and limited health literacy are associated with poor health outcomes among patients with heart failure residing in rural areas

BACKGROUND

Cognitive impairment and limited health literacy are prevalent among patients with heart failure, particularly those residing in rural areas, and are linked to poor health outcomes. Little is known about the intricate relationships among cognitive function, health literacy, and rehospitalization and death in rural patients with heart failure.

OBJECTIVES

To determine the relationships among cognitive function, health literacy, and cardiac event-free survival (ie, heart failure hospitalizations and cardiac mortality) in rural patients with heart failure.

METHODS

This was a secondary data analysis of a randomized controlled trial of 573 rural patients with heart failure. Cognitive function was measured using the Mini-Cog test. Health literacy was measured by the Short Test of Functional Health Literacy in Adults. Cardiac event-free survival was followed for 2 years. Survival analyses (ie, Kaplan-Meier plots with log-rank test and Cox regression) were used.

RESULTS

Cognitive impairment was associated with limited health literacy. Cognitive impairment and limited health literacy predicted worse cardiac event-free survival (P<.05). Patients with both cognitive impairment and limited health literacy had a 2.24 times higher risk of experiencing a cardiac event compared to those without cognitive impairment and with adequate health literacy (P<.001).

CONCLUSIONS

Patients with cognitive impairment and limited health literacy were at the highest risk of experiencing a cardiac event. It is important to screen rural patients with heart failure for cognitive impairment and limited health literacy. Interventions to improve outcomes need to be developed to target rural patients who have heart failure with cognitive impairment and limited health literacy.

Nutrition literacy and its relationship with diet quality and quality of life among white-collar employees: a study from Türkiye

BACKGROUND

Nutrition literacy is an important component of health and healthy eating behaviors. The aim of this study was to determine the nutrition literacy (NL) status of white-collar employees and its relationship with adherence to the Mediterranean diet, anthropometric measurements, and lifestyle behaviors, including eating habits, dietary intake, and physical activity level.

METHODS

This cross-sectional study was conducted with 3459 white-collar employees aged 18-65 who lived in Türkiye. A questionnaire prepared by the researchers was used to obtain information about the demographic characteristics and anthropometric measurements of the participants. Evaluation Instrument of Nutrition Literacy on Adults (EINLA) was used to assess NL, the Mediterranean Diet Adherence Screener (MEDAS) was used to assess diet quality, and the Quality of Life Test Short Form-36 (SF-36) was used to determine quality of life. Data analysis was conducted using the IBM SPSS Statistics 21.0 program.

RESULTS

With an average age of 24.3 ± 10.5 years and 50.7% women, women presented higher nutrition literacy than men did (p < 0.001). Most participants held university or postgraduate degrees with medium to high income levels and the majority demonstrated sufficient NL. Compared with other participants, those with adequate NL had significantly higher Mediterranean diet adherence, and SF-36 physical (77.27 ± 16.26), and mental (65.45 ± 17.00) scores (p < 0.001). Negative correlations were found between the EINLA score and BMI (r=-0.082), waist circumference (r=-0.072), hip circumference (r=-0.036), waist/hip ratio (r=-0.074), and waist/height ratio (r=-0.056) (p < 0.05). Additionally, weak positive correlations were observed between the EINLA score and the SF-36 physical (r = 0.158) and mental scores (r = 0.088), as well as the metabolic equivalent of task (MET) score (r = 0.042) (p < 0.05).

CONCLUSIONS

The results of this study demonstrated that NL is a significant predictor of anthropometric measurements and healthy lifestyle behaviors including dietary habits, and quality of life among adults. Nutrition literacy can enable individuals to make informed choices and thus contribute to the prevention of many noncommunicable chronic diseases.

Adherence to istradefylline in patients with Parkinson's disease: A group-based trajectory analysis

BACKGROUND

Understanding the different patterns of adherence to istradefylline treatment is essential to identifying Parkinson's disease (PD) patients who might benefit from targeted interventions.

OBJECTIVES

This descriptive study aimed to identify longitudinal istradefylline adherence patterns and to characterize factors associated with them.

METHODS

We identified PD patients aged 21-99 years who initiated istradefylline treatment in a Japanese hospital administrative database. Group-based trajectory modeling was used to model the monthly proportion of days covered over time to identify distinct 360-day adherence patterns. Factors associated with each adherence pattern were assessed using univariable multinomial logistic regression models.

RESULTS

Of 2088 eligible PD patients, 4 distinct adherence groups were identified: consistently high adherence (56.8%); rapidly declining adherence (25.8%); gradually declining adherence (8.5%); and gradually declining and then recovering adherence (9.0%). Compared to the consistently high adherence group, the other groups had the following characteristics associated with a likelihood of lower adherence: the rapidly declining adherence group received fewer dopamine agonists (63.8% vs. 69.4%), monoamine oxidase B (MAO-B) inhibitors (26.8% vs. 31.6%), and catechol-O-methyl transferase inhibitors (31.6% vs. 37.0%) and had a higher prevalence of anxiety/mood disorders (29.9% vs. 24.6%); the gradually declining adherence group received fewer MAO-B inhibitors (22.5% vs. 31.6%) and amantadine (8.4% vs. 16.1%) and had a higher prevalence of mild cognitive impairment/dementia (27.0% vs. 18.8%); and the declining and then recovering adherence group had a higher prevalence of anxiety/mood disorders (34.2% vs. 24.6%).

CONCLUSIONS

Clinicians should be aware of the heterogeneous patterns of adherence to istradefylline.

The Dynamics of Cardiovascular Risk-An Analysis of the Prospective Urban Rural Epidemiology (PURE) Poland Cohort Study

Background: The purpose of this study was to analyze the major cardiovascular risk (CVR) factors and their trends in the study population. Methods: The results of subjects in the Polish Prospective Urban and Rural Epidemiological Study (PURE) study group were interpreted. CVR was calculated for each participant according to the Systematic Coronary Risk Evaluation (SCORE2) scale or the Systematic Coronary Risk Evaluation-Older Persons (SCORE2-OP) scale. Data from the beginning of the analysis (2013) and nine years later (2022) were included. In addition, the use of lipid-lowering therapy (LLT) and meeting the low-density lipoprotein cholesterol (LDL-c) target criterion at the beginning and end of the study were analyzed. Results: Patients in the high and very high CVR groups who had abnormal LDL-c results accounted for 64% and 91% of their group in 2013 and 70% and 92% in 2022, respectively. Conclusions: Regardless of age, patients using LLT at the start of the analysis had a greater increase in future CVR, especially if they had lipid abnormalities at the start of the study. This may be due to reverse causality and multimorbidity in these patients, highlighting the importance of appropriate treatment of lipid abnormalities.

Educational status affects prognosis of patients with heart failure with reduced ejection fraction: A post-hoc analysis from the WARCEF trial

AIMS

The influence of social determinants of health (SDOH) on the prognosis of Heart Failure and reduced Ejection Fraction (HFrEF) is increasingly reported. We aim to evaluate the contribution of educational status on outcomes in patients with HFrEF.

METHODS

We used data from the WARCEF trial, which randomized HFrEF patients with sinus rhythm to receive Warfarin or Aspirin; educational status of patients enrolled was collected at baseline. We defined three levels of education: low, medium and high level, according to the highest qualification achieved or highest school grade attended. We analysed the impact of the educational status on the risk of the primary composite outcome of all-cause death, ischemic stroke (IS) and intracerebral haemorrhage (ICH); components of the primary outcome were also analysed as secondary outcomes.

RESULTS

2295 patients were included in this analysis; of these, 992 (43.2%) had a low educational level, 947 (41.3%) had a medium education level and the remaining 356 (15.5%) showed a high educational level. Compared to patients with high educational level, those with low educational status showed a high risk of the primary composite outcome (adjusted hazard ratio [aHR]: 1.31, 95% confidence intervals [CI] 1.02-1.69); a non-statistically significant association was observed in those with medium educational level (aHR: 1.20, 95%CI: .93-1.55). Similar results were observed for all-cause death, while no statistically significant differences were observed for IS or ICH.

CONCLUSION

Compared to patients with high educational levels, those with low educational status had worse prognosis. SDOH should be considered in patients with HFrEF.

Relationship between the Health Literacy and Self-Medication Behavior of Primary Health Care Clientele in the Hail Region, Saudi Arabia: Implications for Public Health

BACKGROUND AND AIM

Because they are unaware of the potential adverse effects of medications, people frequently self-medicate as a form of self-care. This study aimed to investigate the factors associated with health literacy and the propensity to self-medicate among the primary healthcare clientele of the city of Hail, Saudi Arabia.

METHODS

This research employed a cross-sectional approach with the participation of 383 primary health center clientele of the Hail Region of Saudi Arabia. Participation was enacted via convenience sampling from December 2022 to February 2023. The data were collected using a self-administered questionnaire. The investigation utilized descriptive statistics as well as multiple linear regression and correlation for the data analysis.

RESULTS

Participants who were aged 30 years and above, single, had a college degree, were non-Saudi, had a white-collar occupation and received information from the internet/Google/YouTube had a significant relationship (p < 0.05) with health literacy. On the self-medication scale (SMS), there were significant relationships with age, marital status, educational level and occupation (p < 0.05). The nationality and source of information factors related to health had a positively significant effect on health literacy (p < 0.01), while middle age (24-29 years) had a positive effect on the self-medication scores (p < 0.01). There was a significant positive correlation between the health literacy screening scale (BRIEF) and the self-medication scale (SMS) scores (r = 421, p < 0.001).

CONCLUSION

Age of 30 years old or above, single status, a college degree, non-Saudi status, white-collar occupation and receiving information from the internet/Google/YouTube were all significant for health literacy. There were also significant relationships with the SMS scores for age, marital status, educational level and occupation. The factors affecting health literacy were older participant age, nationality and the source of information regarding health. Conversely, among the participants, being in the middle-aged group (24-29 years) was a factor that affected their self-medication scores. There was a significant positive correlation between the health literacy screening scale (BRIEF) and the self-medication scale (SMS).

The design and rationale of a multicenter real-world trial: The Southeastern Collaboration to Improve Blood Pressure Control in the US Black Belt - Addressing the Triple Threat

BACKGROUND

Impoverished African Americans (AA) with hypertension face poor health outcomes.

PURPOSE

To conduct a cluster-randomized trial testing two interventions, alone and in combination, to improve blood pressure (BP) control in AA with persistently uncontrolled hypertension.

METHODS

We engaged primary care practices serving rural Alabama and North Carolina residents, and in each practice we recruited approximately 25 AA adults with persistently uncontrolled hypertension (mean systolic BP >140 mmHg over the year prior to enrollment plus enrollment day BP assessed by research assistants ≥140/90 mmHg). Practices were randomized to peer coaching (PC), practice facilitation (PF), both PC and PF (PC + PF), or enhanced usual care (EUC). Coaches met with participants from PC and PC + PF practices weekly for 8 weeks then monthly over one year, discussing lifestyle changes, medication adherence, home monitoring, and communication with the healthcare team. Facilitators met with PF and PC + PF practices monthly to implement ≥1 quality improvement intervention in each of four domains. Data were collected at 0, 6, and 12 months.

RESULTS

We recruited 69 practices and 1596 participants; 18 practices (408 participants) were randomized to EUC, 16 (384 participants) to PF, 19 (424 participants) to PC, and 16 (380 participants) to PC + PF. Participants had mean age 57 years, 61% were women, and 56% reported annual income <$20,000.

LIMITATIONS

The PF intervention acts at the practice level, possibly missing intervention effects in trial participants. Neither PC nor PF currently has established clinical reimbursement mechanisms.

CONCLUSIONS

This trial will fill evidence gaps regarding practice-level vs. patient-level interventions for rural impoverished AA with uncontrolled hypertension.

Estimation of health literacy levels in patients with cardiovascular diseases in a Gulf country

INTRODUCTION

Cardiovascular diseases (CVDs) are the leading cause of mortality worldwide. In the United Arab Emirates (UAE), the prevalence of deaths associated with CVD is higher than the global average, and the incidence of premature coronary heart disease is 10-15 years earlier than in Western nations. In patients with CVD, inadequate health literacy (HL) is significantly associated with poor health outcomes. The goal of this study is to assess HL levels among patients with CVD in the UAE to develop effective health system strategies for disease prevention and management.

METHODS

A nationwide cross-sectional survey to assess HL levels in patients with CVD was conducted between January 2019 and May 2020 in the UAE. The association between health literacy level with patient age, gender, nationality, and education was determined using the Chi-Square test. The significant variables were further analyzed by ordinal regression.

RESULTS

Of 336 participants (86.5% response rate), approximately half 51.5% (173/336) of the respondents were women, and 46% (146/336) of them attained high school level of education. More than 75% (268/336) of the participants were above the age of 50 years. Overall, 39.3% (132/336) of respondents possessed inadequate HL, and 46.4% (156/336) and 14.3% (48/336) demonstrated marginal and adequate HL, respectively. Inadequate health literacy was more prevalent among women, as compared to men. Age was significantly associated with HL levels. Participants under age 50 had higher adequate HL levels 45.6% (31/68), (95% CI (3.8-57.4), P < 0.001). There was no correlation between education and health literacy levels.

CONCLUSION

The inadequate HL levels found in outpatients with CVD is a major health concern in the UAE. To improve population health outcomes, health system interventions, including targeted educational and behavioral programs for the older population are necessary.

Health literacy, self-efficacy, self-care behaviors, and glycemic control among older adults with type 2 diabetes mellitus: a cross-sectional study in Thai communities

BACKGROUND

Properly understanding the health information of people with type 2 diabetes mellitus (T2DM) is the basis for better risk factor management, which also positively affects their quality of life. The aim of this study was to investigate diabetes health literacy (HL), self-efficacy, and self-care behaviors associated with glycemic control among older adults with T2DM in northern Thai communities.

METHODS

A cross-sectional study was conducted among 414 older adults over the age of 60 diagnosed with T2DM. The study was conducted in Phayao Province from January to May 2022. Simple random sampling of the patient list for the Java Health Center Information System program was used. Questionnaires were used to collect data on diabetes HL, self-efficacy, and self-care behaviors. Blood samples were tested for estimated glomerular filtration rate (eGFR) and glycemic controls, such as fasting blood sugar (FBS) and glycated hemoglobin (HbA1c).

RESULTS

The mean age of participants was 67.1 years. FBS (mean ± SD = 108.5 ± 29.5 mg/dL) and HbA1c (mean ± SD = 6.6 ± 1.2%) levels were found to be abnormal in 50.5% (≥ 126 mg/dL) and 17.4% (≥ 6.5%) of the subjects, respectively. There was a strong correlation between HL and self-efficacy (r = 0.78), HL and self-care behaviors (r = 0.76), and self-efficacy and self-care behaviors (r = 0.84). The eGFR was significantly correlated with diabetes HL (r = 0.23), self-efficacy (r = 0.14), self-care behaviors (r = 0.16), and HbA1c (r = -0.16) scores. Linear regression after adjusting for sex, age, education, DM duration, smoking, and drinking alcohol showed that FBS level was inversely associated with diabetes HL (Beta = -0.21, R² = 11.0%), self-efficacy (Beta = -0.43, R² = 22.2%), and self-care behavior (Beta = -0.35, R² = 17.8%), whereas HbA1C level was negatively associated with diabetes HL (Beta = -0.52, R² = 23.8%), self-efficacy (Beta = -0.39, R² = 19.1%), and self-care behavior (Beta = -0.42, R² = 20.7%).

CONCLUSION

Diabetes HL was related to self-efficacy and self-care behaviors in elderly T2DM patients and was shown to influence their health, including glycemic control. These findings suggest that implementing HL programs to build competence in self-efficacy expectations is important for contributing to improvements in diabetes preventive care behaviors and HbA1c control.

Patient Beliefs on Antibiotic Prescribing in Primary Care: A Cross-Sectional Survey in Saudi Arabia

Background Antibiotic overuse is a critical global health issue, and patient attitudes and expectations play a significant role in the inappropriate use of antibiotics. Limited research has been conducted on patient knowledge, attitudes, and perceptions of antibiotic use in Saudi Arabia. This survey aimed to assess patients' knowledge and attitudes related to antibiotic use in Jeddah, Saudi Arabia. Methods A cross-sectional survey using a convenience sampling method was conducted in Saudi Arabia. An online self-administered questionnaire was used to collect demographic data, antibiotic knowledge, and attitudes. Results The study included 400 patients, with a mean age of 39 years and an equal gender distribution (54% female). Most participants (75%) had not used antibiotics in the past year. Patients demonstrated moderate knowledge about antibiotics, with 81% recognizing that antibiotics can cause side effects and 69% knowing that overuse can lead to resistance. However, only 44% knew that antibiotics are not effective for all infections, and only half (50%) knew that antibiotics work against bacteria, not viruses. Patients held mixed attitudes toward antibiotic prescribing, with 25% believing it was essential to take antibiotics for every infection and 44% believing healthcare providers should prescribe antibiotics for respiratory tract infections. Logistic regression analyses showed that patient expectations for antibiotic prescribing were strongly associated with inappropriate antibiotic use. In contrast, patient satisfaction with antibiotic prescribing was negatively associated with inappropriate antibiotic use. Lower health literacy levels were also associated with inappropriate antibiotic use. Conclusion The study underscores the need for interventions that promote patient education and communication to ensure appropriate antibiotic use in primary care. Patient attitudes and beliefs, such as their expectations for antibiotic prescribing and health literacy levels, were identified as significant predictors of inappropriate antibiotic use.

The effect of health literacy in explaining medication adherence among patients with hypertension: A cross-sectional study of Syrian refugees in Jordan

BACKGROUND

Poor medication adherence is a concern among patients with hypertension. However, few studies have assessed the effect of health literacy on medication adherence among refugee patients.

AIM

The aim was to examine the effect of health literacy and associated factors in explaining medication adherence among Syrian refugee patients with hypertension.

METHODS

A cross-sectional study was used, recruiting 150 Syrian refugees with hypertension in February 2020. The Hill-Bone scale and the Health Literacy Questionnaire were used to collect data, which were analysed using descriptive and inferential statistics.

RESULTS

Participants had low levels of medication adherence and had low mean scores in eight of nine subscales of the health literacy scale, except in the appraisal of health information subscale. Factors including patient's age, marital status, the number of medications and co-morbid diseases were significantly associated with medication adherence. Age, understanding written health information and ability to engage with healthcare providers were predictive of medication adherence.

CONCLUSION

To increase medication adherence among refugee patients with hypertension, nurses need to improve patients' health literacy and understanding of health information about their disease.

Health literacy and ophthalmology: A scoping review

As of 2020, it is estimated that 43.3 million people are blind, and an additional 553 million have mild to severe vision impairment.50 At least 1 billion worldwide have a vision impairment that could have been prevented or has yet to be addressed.54 Poor health literacy may be a significant contributor to the prevalence of eye disease. With implications on disease burden, progression, and health outcomes, a greater understanding of the role health literacy plays in ophthalmology is needed. This is the first scoping review to assess the impact of health literacy on eye health outcomes and blindness, including ocular screening rates and/or follow-up rates, treatment adherence, and self-care practices. PubMed, Embase, and CINAHL databases were searched systematically through November 12, 2021, and we evaluated the association between health literacy and ophthalmic outcomes in 4 domains: clinical outcomes, treatment adherence rates, screening and/or follow-up rates, and self-care practices. There is evidence to suggest that health literacy is associated with ophthalmic outcomes in all these domains. To better understand how health literacy impacts eye health, further longitudinal studies examining the effect of health literacy (using standardized health literacy measures) on ophthalmic outcomes are needed. We believe a specific ophthalmic health literacy survey could help achieve this goal and help target interventions to ultimately improve outcomes among ophthalmology patients.

Evaluation of the health promotion effect of hepatitis B prevention and treatment in the Zhejiang demonstration area, China

Background

To investigate the health literacy level and health promotion effect of hepatitis B prevention and treatment in the demonstration area of Zhejiang Province.

Methods

The National Science and Technology Major Health Education Group took 6 demonstration areas in Zhejiang Province as the whole research site. After the sample size (N=2160 people) was determined, a multistage stratified cluster sampling method was used to conduct a questionnaire survey in 2018 (before health education) and 2019 (after health education). Stata 12 statistical software was used to analyse the status and improvement rate of hepatitis B health literacy of residents in the demonstration area before and after health education and compare the health promotion effects of different health intervention methods.

Results

Before and after health education, there was no significant difference in the basic information of the subjects (P>0.05). After the health education intervention, the level of hepatitis B health literacy of residents in the demonstration area increased by 11.8%, and the difference was statistically significant (P < 0.001). The awareness rate of hepatitis B transmission was low before health education but increased after health education. The form of "Internet +" health education may better improve the residents' health literacy level about hepatitis B prevention and treatment.

Conclusion

After health education, the level of health literacy of residents in the Zhejiang demonstration area about hepatitis B prevention and control significantly improved, but there is room for further improvement. In the future, targeted health education intervention should be carried out, and the health education mode of "Internet +" can achieve better results to effectively prevent and control hepatitis B.

Translation and validation of the Arabic version of the Morisky, Green and Levine (MGL) adherence scale

The Morisky Green Levine (MGL) adherence scale is a 4-item tool used for the detection of medication nonadherence among patients with chronic health conditions. Despite being widely used in Arabic-speaking research contexts, it has never been validated in Arabic language. The aim of this study was to translate and validate the MGL tool into Arabic. A standard forward-backward process was used to translate the questionnaire. Cronbach’s alpha coefficient was measured to assess internal consistency of the scale. The test-retest reliability measured the consistency of participants’ responses over time. Construct validity was evaluated by Explanatory factor analysis (EFA); Kaiser-Meyer-Olkin value and Bartlett’s test of sphericity were determined. Convergent validity was assessed using a preexisting medications Arabic Adherence Assessment Tool (AAAT). The model fit was evaluated using confirmatory factor analysis (CFA). Associations between the MGL scale scores and the patient demographic/clinical characteristics were tested by linear regressions. A total of 201 participants were included into the study. The MGL scale categorization revealed that 20.9%, 59.2% and 19.9% of the participants had high, moderate and low levels of adherence respectively. Adequate internal consistency (alpha = 0.593) was observed. A significant strong ICC and Pearson’s correlations were generated between responses at time 1 and time 2. EFA results elucidated the suitability of the data for factor analysis. Pearson’s coefficient (r) revealed a significant strong correlation between MGL scale and AAAT. CFA results confirmed a good fit for the suggested model. Linear regression revealed higher number of medications, more frequent outpatient clinic visits and not experiencing medication adverse effect factors significantly associated with better adherence. The Arabic version of MLG scale is a reliable valid tool to assess adherence among Arabic-speaking communities. Implementing interventions targeting patients not compliant to regular clinic visits and those at higher risk of experiencing medication side effects can greatly enhance medication adherence.

Tools to Measure Health Literacy among Adult Hispanic Populations with Type 2 Diabetes Mellitus: A Review of the Literature

Health literacy (HL) is associated with short- and long-term health outcomes, and this is particularly relevant in Hispanics, who are disproportionally affected by lower HL. Hispanics have become the largest minority population in the United States. Also, Hispanics experience higher burdens of chronic diseases such as type 2 diabetes mellitus (T2DM) than non-Hispanic whites. Thus, effectively choosing culturally appropriate validated instruments that measure a marker found in health assessments should be a serious consideration. Using a systemized approach, we identified and reviewed 33 publications and found eight different HL and numeracy (separate or combined) instruments. We assessed the study designs and instrument structures to determine how HL was measured across these studies. We categorized the results into direct and indirect measurements of HL. The Test of Functional Health Literacy in Adults (TOFHLA) family of HL instruments was favored for direct measures of HL, while the Brief Health Literacy Screen (BHLS) instrument was favored for indirect measures. Despite identified trends in instruments used, more comprehensive measurement tools have been developed but not validated in Hispanic populations. In conclusion, further validation of more comprehensive HL instruments in adult Hispanic populations with T2DM could better assess HL levels and improve health promotion efforts.

Systemic Barriers in Receiving Electronically Prescribed Glaucoma Medications

PRCIS

Over a third of electronically prescribed glaucoma medications were not picked up within 1 month of patient request. Feedback-driven protocols may help minimize treatment interruptions attributed to electronic prescribing.

PURPOSE

Glaucoma treatment relies on long-term medication compliance and many socioeconomic factors impact the ability of patients to receive their medications. This study aims to quantify treatment interruptions attributable to electronically prescribed medications and propose interventions to minimize this barrier.

METHODS

This is a cross-sectional study of the electronic prescribing patterns at a tertiary care hospital serving a socioeconomically diverse patient population. Glaucoma medication refill requests received over a 6-week interval were reviewed and patient pharmacies were contacted 1 month after the request date to determine whether the medication was received by the patient. Patients who did not pick up the prescriptions were contacted and consented to participate in a survey to identify the barriers to acquiring the medications.

RESULTS

Refill requests of 198 glaucoma medications met the inclusion criteria and the most common classes were prostaglandin analogs (44%) and alpha-2-agonists (21%). Medications were not obtained within 1 month in 71 (35.9%) cases. Prior authorization requirement was significantly associated with patients not obtaining their medication (odds ratio, 0.07; 95% confidence interval, 0.03-0.45). Patient reported challenges to successful receipt electronically prescribed medications included insurance coverage (32.2%) and pharmacy availability (22.6%).

CONCLUSIONS

Approximately a third of electronically prescribed glaucoma medications were not received by patients within a month of refill request due to the need for prior authorization, insurance coverage, and pharmacy availability. A mechanism to alert providers and to address these barriers to medication access may minimize treatment interruption and disease progression.

Body mass index, body fat percentage, and visceral fat as mediators in the association between health literacy and hypertension among residents living in rural and suburban areas

Background

Hypertension is a major cause of death and disability worldwide. Enhancing health literacy (HL) may help to alleviate the risk of hypertension and its burden. However, evidence on the association between HL and hypertension and potential mechanisms remain to be explored.

Objectives

This study examined the association between HL and hypertension; and explored whether body mass index (BMI), body fat percentage (PBF), and visceral fat (VF) were mediators of this association in people who resided in rural and suburban areas in Vietnam.

Methods

A cross-sectional survey was conducted from 1st July to 31st December 2019, involving 1655 residents and exploring participants' sociodemographic characteristics, HL, health-related behaviors, comorbidities, body composition, and blood pressure (BP). People with systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg or using antihypertensive medication were classified as having hypertension. Multiple logistic regression and mediation analyses were used to explore associations.

Results

The hypertension prevalence was 41.9% (694/1,655). In adjusted models, a higher HL score was associated with a lower hypertension likelihood (OR = 0.96; 95%CI = 0.95–0.97; p < 0.001). Factors associated with a higher odd of hypertension were overweight/obese (OR = 1.69; 95%CI = 1.24–2.29; p = 0.001), high PBF (OR = 2.35; 95%CI = 1.85–2.99; p < 0.001), and high VF (OR = 2.27; 95%CI = 1.63–3.16; p < 0.001). Notably, PBF significantly mediated the association between HL and hypertension (indirect effect, OR = 0.99; 95%CI = 0.98–0.99; p = 0.009; percent mediated = 8.56%). The mediating roles of BMI and VF were not found.

Conclusion

The prevalence of hypertension was relatively high. People with better HL were less likely to have hypertension. The association between HL and hypertension was partially explained by PBF. Strategic approaches are required to improve people's HL and body fat which further help to manage hypertension in rural and suburban areas.

Patient judgments about hypertension control: the role of patient numeracy and graph literacy

OBJECTIVE

To assess the impact of patient health literacy, numeracy, and graph literacy on perceptions of hypertension control using different forms of data visualization.

MATERIALS AND METHODS

Participants (Internet sample of 1079 patients with hypertension) reviewed 12 brief vignettes describing a fictitious patient; each vignette included a graph of the patient's blood pressure (BP) data. We examined how variations in mean systolic blood pressure, BP standard deviation, and form of visualization (eg, data table, graph with raw values or smoothed values only) affected judgments about hypertension control and need for medication change. We also measured patient's health literacy, subjective and objective numeracy, and graph literacy.

RESULTS

Judgments about hypertension data presented as a smoothed graph were significantly more positive (ie, hypertension deemed to be better controlled) then judgments about the same data presented as either a data table or an unsmoothed graph. Hypertension data viewed in tabular form was perceived more positively than graphs of the raw data. Data visualization had the greatest impact on participants with high graph literacy.

DISCUSSION

Data visualization can direct patients to attend to more clinically meaningful information, thereby improving their judgments of hypertension control. However, patients with lower graph literacy may still have difficulty accessing important information from data visualizations.

CONCLUSION

Addressing uncertainty inherent in the variability between BP measurements is an important consideration in visualization design. Well-designed data visualization could help to alleviate clinical uncertainty, one of the key drivers of clinical inertia and uncontrolled hypertension.

Health literacy and prognosis of heart failure: a prospective propensity-matched study in the community

AIMS

Health literacy (HL), the ability to obtain and understand health information, is critical to self-care in chronic disorders. A low HL is common among these patients and has been associated with a worse prognosis. Nevertheless, the relationship between HL and the prognosis of heart failure (HF) with reduced (HFrEF) vs. preserved (HFpEF) ejection fraction remains unsettled. To analyse the relationship between HL and the prognosis of patients with incident HFrEF and HFpEF.

METHODS AND RESULTS

Prospective study over 10 years (2010-19) on 6444 patients diagnosed with incident HF. The main outcomes were mortality, hospitalizations, and visits to emergency services. The independent relationship between HL and the prognosis, stratifying patients for cardiovascular comorbidity after propensity score-matching was analysed.After matching 5355 HF patients, 1785 with low HL (874 with HFrEF and 911 with HFpEF) vs. 3570 with adequate HL (1748 with HFrEF and 1822 with HFpEF), during a median follow-up of 5.41 years, 3874 patients died (72.3%) and 3699 patients were hospitalized (69.1%). After adjustment for potential confounders, an adequate HL was associated with a lower all-cause and cardiovascular mortality, less hospitalizations, and less 30-day readmissions [relative risk (RR) for HF <0.72 (0.66-0.86), RR for HFrEF <0.69 (0.63-0.95), and RR for HFpEF <0.62 (0.55-0.88), P < 0.001 in all cases], both for patients with HFrEF and HFpEF. Analyses of recurrent hospitalizations gave larger HL effects than time-to-first-event analyses.

CONCLUSIONS

In this propensity-matched study, a low HL is associated with a worse prognosis of patients with incident HFrEF and HFpEF.

A VOSviewer-Based Bibliometric Analysis of Prescription Refills

Purpose

Prescription refills are long-term prescriptions for chronic patients in stable status, which varies from country to country. A well-established prescription refill system is beneficial for chronic patients’ medication management and facilitates the efficacy of clinical care. Therefore, we carried out a bibliometric analysis to examine the development of this field.

Summary

Publications on prescription refills from 1970 to 2021 were collected in the Web of Science Core Collection (WoSCC). Search strategy TS = “prescri* refill*” OR “medi* refill*” OR “repeat prescri*” OR “repeat dispens*” OR TI = refill* was used for search. VOSviewer was applied to visualize the bibliometric analysis. A total of 319 publications were found in WoSCC. Study attention on prescription refills has shown a steady rise but is still low in recent years. The United States was the most productive country, which had the highest total citations, average citations per publication, and the highest H-index, and participated in international collaboration most frequently. The University of California system was the most productive institution. The U.S. Department of Veterans Affairs was the institution with the most citations, most average citation, and highest H-index. Sundell was the most productive author, and Steiner J. F. was the most influential author. “Adherence,” “medication,” and “therapy” were the most prominent keywords.

Conclusion

Publications on prescription refills have increased rapidly and continue to grow. The United States had the leading position in the area. It is recommended to pay closer attention to the latest hotspots, such as “Opioids,” “Surgery,” “Differentiated care,” and “HIV.”

Health literacy in context: struggling to self-manage diabetes - a longitudinal qualitative study

OBJECTIVES

Considering health literacy needs is a key component of health services responsiveness to diabetes self-management among vulnerable individuals. The purpose of this qualitative study was to provide a detailed analysis of the health literacy of people with type 2 diabetes in relation to their daily self-care practices.

DESIGN

Nested qualitative study in the ERMIES randomised controlled trial testing a 2-year structured care in type 2 diabetes. First round of semidirected interviews at the beginning of the trial with thematic analysis of content. Second round at the completion with directed interviews guided by the first round's themes together with Health Literacy Questionnaire.

SETTINGS

Interviews conducted at home.

PARTICIPANTS

Forty-four (31 females/13 males, 30-79 years, glycated haemoglobin (HbA1c)≥7.5%) consecutive participants out of 100 recruited in the ERMIES trial from 4 diabetology outpatient settings (Reunion Island). Forty-two respondents to the second round interviews.

RESULTS

Three poles structured into eight themes characterised practices in context: health knowledge, disease management, expertise and social support. The relationships of participants in each of the eight themes were differentiated, ranging from functional to interactive and critical. Treatment and follow-up were essentially functional, while diet and exercise remained more interactive. Social support and relationship to health professionals were important determinants of disease management.

CONCLUSIONS

Treatment management and disease monitoring remain primarily the job of health professionals, as opposed to diet, physical activity and social support being part of ordinary practice. Decision-making, as a shared social task, as well as resources for participation in health services, should be considered for relevant interventions in type 2 diabetes.

Health Information Sources Influencing Health Literacy in Different Social Contexts across Age Groups in Northern Thailand Citizens

Health literacy is an essential social determinant of health and has been associated with positive health outcomes. While many sources of health information are widely available, people of different ages also have diverse social contexts and preferences for health information sources. This study aimed to identify health information sources and socio-demographics influencing health literacy in different social contexts across age groups: 15–29 years (young), 30–59 years (middle-age), and ≥60 years (elderly). We obtained secondary data from a cross-sectional study in northern Thailand from March to August 2019. Multivariate linear regression with age group subgroup analysis was used to determine factors associated with general health literacy by the Thai version of the health literacy questionnaire. Receiving health information from physicians was significantly associated with higher general health literacy in young (β 6.45, 95%CI 0.44–12.45; p = 0.035) and elderly (β 5.18, 95%CI 1.84–8.52; p = 0.002) groups, while receiving health information from health volunteers was significantly associated with a higher general health literacy in the middle-aged (β 2.89, 95%CI 0.38–5.39; p = 0.024) group. Although younger participants showed more frequent access to health information via the media than the other age groups, there were no media sources significantly linked with their general health literacy. Health information from physicians is a vital source of health information.

Development and Validation of a Food and Nutrition Literacy Questionnaire for Chinese Adults

The purpose of this study aimed to develop and validate the Food and Nutrition Literacy Questionnaire for Chinese adults (FNLQ). The dimensions and core components of Food and Nutrition Literacy were constructed though literature review and qualitative consensus study. A cross-sectional survey of 8510 participants was conducted. The reliability of the questionnaire was determined by internal consistency, the construct validity was assessed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and the content validity was assessed by the Pearson correlation coefficient. From the literature review and qualitative methods, 20 core components and 50 questions of the FNLQ were developed, including 1 dimension of knowledge and 3 practice dimensions (ability of selection, preparing food and eating). The overall FNLQ questionnaire had good reliability and validity (Cronbach’s α = 0.893, χ2/DF = 4.750, RMSEA = 0.048, GFI = 0.891 and AGFI = 0.876). The average FNLQ score of all participants was (64.08 ± 12.77), and the score for the knowledge and understanding dimension was higher than that for the practice dimensions. In addition, 80 was set as the nutritional literacy threshold, and only 12.2% met this threshold in this survey. Sociodemographic and health status characteristics were predictors of FNLQ (R2 = 0.287, F = 244.132, p < 0.01). In conclusion, the FNLQ built in this study had good validity and reliability. It could be considered as a reliable tool to assess Food and Nutrition Literacy of Chinese adults.

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.

Association of health literacy and medication adherence with health-related quality of life (HRQoL) in patients with ischemic heart disease

BACKGROUND

Medication Adherence (MA) and Health Related Quality of Life (HRQoL) are two inter-connected concepts, co-influenced by Health Literacy (HL), with significant impact on patient management and care. Thus, we aimed to estimate the association of HL and MA with HRQoL in IHD patients.

METHODS

Cross-sectional study of 251 IHD patients recruited from Lahore over 6 months period. HL, MA and HRQoL was assessed using validated questionnaires; 16-items of HL, Morisky Green Levine Scale (MGLS) and SF-12, respectively. Chi-square for significance, logistic-regression for association and linear regression for predictions were used.

RESULTS

IHD patients; males (p = 0.0001), having secondary-higher education (p = 0.0001), middle/upper class (p = 0.0001) and employed (p = 0.005) had adequate HL, and were more likely to be adherent (OR; 4.3, p = 0.014). Both physical (PCS-12) and mental (MCS-12) component scores of HRQoL for age, gender, education, area of residence, employment and MA were significantly higher in patients with adequate HL. In multinomial regression, improved PCS-12 scores tend to be higher in subjects having secondary-higher education (OR; 3.5, p = 0.067), employed (OR; 6.1, p = 0.002) and adherent (OR; 2.95, p = 0.218), while MCS-12 scores tend to be higher in patients < 65 years (OR; 2.2, p = 0.032), employed (OR; 3, p = 0.002) and adherent (OR; 4, p = 0.004). In adjusted model, HL (β;0.383, p = 0.0001) and MA (β; - 0.133, p = 0.018) were significantly associated with PCS-12, and MCS-12 with MA (β; - 0.161, p = 0.009) only.

CONCLUSION

Data suggested that adequate HL was significantly associated with adherence and both physical and mental dimensions of HRQoL were higher in IHD patients with adequate HL. Besides, HL and MA are independent predictors of HRQoL in IHD patients.

Effects of Objective and Subjective Health Literacy on Patients' Accurate Judgment of Health Information and Decision-Making Ability: Survey Study

Background

Interpreting health information and acquiring health knowledge have become more important with the accumulation of scientific medical knowledge and ideals of patient autonomy. Health literacy and its tremendous success as a concept can be considered an admission that not all is well in the distribution of health knowledge. The internet makes health information much more easily accessible than ever, but it introduces its own problems, of which health disinformation is a major one.

Objective

The objective of this study was to determine whether objective and subjective health literacy are independent concepts and to test which of the two was associated more strongly with accurate judgments of the quality of a medical website and with behavioral intentions beneficial to health.

Methods

A survey on depression and its treatments was conducted online (n=362). The Newest Vital Sign was employed to measure objective, performance-based health literacy, and the eHealth Literacy Scale was used to measure subjective, perception-based health literacy. Correlations, comparisons of means, linear and binary logistic regression, and mediation models were used to determine the associations.

Results

Objective and subjective health literacy were weakly associated with one another (r=0.06, P=.24). High objective health literacy levels were associated with an inclination to behave in ways that are beneficial to one’s own or others’ health (Exp[B]=2.068, P=.004) and an ability to recognize low-quality online sources of health information (β=–.4698, P=.005). The recognition also improved participants’ choice of treatment (β=–.3345, P<.001). Objective health literacy helped people to recognize misinformation on health websites and improved their judgment on their treatment for depression.

Conclusions

Self-reported, perception-based health literacy should be treated as a separate concept from objective, performance-based health literacy. Only objective health literacy appears to have the potential to prevent people from becoming victims of health disinformation.

Age and education as factors associated with medication literacy: a community pharmacy perspective

BACKGROUND

Aging implies a higher prevalence of chronic pathologies and a corresponding increase in medication. The correct adherence and use of the medication are prerequisites for reducing risks of disease progression, comorbidity, and mortality. Medication literacy (ML) is the specific ability to safely access and understand the information available concerning medication, and to act accordingly. Currently, there are few specific instruments that ascertain the extent of ML in the general population. The aim of this work was to analyse ML in a large cohort of pharmacy customers.

METHODS

A total of 400 community pharmacy clients were analyzed to assess the level of ML (documental and numeracy) through the validated MedLitRxSE tool.

RESULTS

The results showed that out of a total of 400 community pharmacy clients only 136 (34%) had an adequate degree of ML, while the rest of the clients (n = 264; 66%) were adjudged not to have this ability. Statistically significant differences were found between the different age groups in terms of ML (P < 0.001; OR = 0.312; 95% CI: 0.195-0.499), the 51-65 and >65-year age groups having a lower frequency of adequate ML (23.5 and 7.1%, respectively) than the rest of the age groups. A statistically significant increase in adequate ML was observed as the academic level of the clients increased (P < 0.001; OR = 15.403; 95% CI: 8.109-29.257). Multivariate logistic regression confirmed the influence of both variables on ML.

CONCLUSIONS

An inadequate ML level was found in community pharmacy clients over the age of 51, and also in those with primary or non-formal studies. Our data add to our knowledge about ML, and should pharmacists and other health professionals to adopt new strategies to prevent, or at least reduce, errors in taking medicines, thus avoiding the undesirable effects of any misuse.

Cardiovascular Diseases Health Literacy among Patients, Health Professionals, and Community-Based Stakeholders in a Predominantly Medically Underserved Rural Environment

OBJECTIVE

The central Appalachian region of the United States is disproportionately burdened with cardiovascular disease (CVD); however, the level of literacy about CVD among residents has not been well studied. This study aimed to examine the prevalence and factors of CVD health literacy (HL) among a sample of patients/caregivers, providers/professionals, and community stakeholders.

METHODS

In 2018, data were collected from central Appalachian residents in six states: Kentucky, North Carolina, Ohio, Tennessee, Virginia, and West Virginia. CVD HL status was determined by assessing correct responses to five interrelated questions about basic knowledge of CVD. Multiple logistic regression analyses were used to examine the associations between potential factors and CVD HL status.

RESULTS

Of the total respondents (N = 82), <50% correctly answered all 5 CVD HL questions. Multiple logistic regression analyses showed that compared with respondents with advanced college degrees, those with a college degree or less were more likely to have low HL for "typical symptom of CVD," "physical exercise and CVD," "blood pressure and CVD," and "stress and CVD." In addition, compared with respondents younger than 50 years, those 50 years and older were 3.79 times more likely to have low HL for "physical exercise and CVD."

CONCLUSIONS

These results suggest the incorporation of CVD HL into CVD care and that educational attainments should be part of CVD policies and programs in the region.

Discrepancy Among Self-Reported Adherence, Prescription Refills, and Actual Anticoagulant Control

BACKGROUND

Patients must adhere to their prescribed warfarin regimens and regularly monitor the anticoagulation effect to maintain therapeutic levels. The ability to evaluate regimen adherence accurately is crucial to the success of patient coaching. However, prevention of thromboembolic events is challenging when the association between medication adherence and the actual amount of anticoagulant agent taken cannot be determined.

PURPOSE

This study used self-reported medication taken and prescription refills to (a) verify warfarin medication adherence and (b) assist clinicians to determine the discrepancy between medication adherence and anticoagulant control efficacy.

METHODS

This study was conducted at a national-university-affiliated hospital in Yilan County, Taiwan. Structured questionnaires and medical record reviews were adopted. A 100-point visual analog scale was used to measure the reported adherence of participants, whereas medication refill adherence was compared against self-reported adherence. Finally, degree of adherence was evaluated based on time in therapeutic range.

RESULTS

This study included 192 participants. Half (n = 94, 49%) were women, and the mean age was 69.6 years. Mean scores were 92.2% for the visual analog scale and 87.3% for medication refill adherence. Medication adherence correlated significantly with age, as reflected in the visual analog scale scores (p < .05). The participants who were receiving polypharmacy with five types of medicines or less attained higher visual analog scale scores, whereas participants who were on warfarin for 2-12 months exhibited higher medication refill adherence. Time in therapeutic range correlated negatively with age, although stability improved with therapy duration.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Despite their high self-reported adherence levels, patients of advanced age require careful monitoring of their time in therapeutic range. The participants in this study who were on warfarin for a relatively longer time exhibited higher stability in the therapeutic range, despite their low medication refill adherence. The results of this study suggest that patient age, duration of warfarin therapy, and polypharmacy are factors associated with medication adherence. The findings may facilitate future assessments of warfarin adherence in patients as well as the implementation of more effective clinical nursing procedures and management practices.

Development, validation and performance of a newly designed tool to evaluate functional medication literacy in Slovenia

Background Medication literacy refers to the ability of individuals to safely and appropriately access, understand and act on basic medication information. It is vital for correctly and safely using medications. General health literacy measures do not adequately address specific skills for medication literacy, and there are no general, self-administered, performance-based instruments for assessing patients' medication literacy. Objective The aim was to develop and validate a self-administered performance-based questionnaire measuring functional medication literacy and to evaluate functional medication literacy among the Slovenian general population. Setting A random sample of adult Slovenian residents received the questionnaires at their home addresses. Method The initial content was derived from medication counselling literature. Thirteen patients and 14 healthcare professionals provided feedback about its comprehensibility, comprehensiveness, and difficulty thus supporting content and face validity. The developed questionnaire, comprising 30 items divided into 5 categories (dosage, adverse effects, interactions, precautions, and other information), was sent to a random sample of 1500 adult Slovenian residents. The overall validity of the questionnaire was assessed via reliability, criterion and discriminant validity using the Kuder-Richardson Formula 20, multiple linear regression and Mann-Whitney test. Descriptive statistics were used to evaluate medication literacy. Main outcome measure The psychometric properties of the questionnaire (reliability, content, face, criterion, and discriminant validity); level of functional medication literacy. Results A total of 402 residents returned eligible questionnaires (26.8% response rate). The Kuder-Richardson Formula 20 reliability coefficient for the whole questionnaire was 0.823. One item that did not demonstrate discriminant validity was deleted. Criterion validity was supported by a significant association between age and medication literacy (β = - 0.303). Income (β = 0.243) and current self-perceived health (β = 0.187) also were associated with medication literacy. The median of medication literacy score was 24 out of 29 points. Dosage-related items requiring understanding of long text instructions and the use of numeracy skills received the most incorrect answers. Conclusion A performance-based questionnaire measuring functional medication literacy among a general population with supported validity was developed. Slovenian residents encountered difficulties when dealing with items requiring prose literacy and numeracy skills, especially related to dosing. Special attention should be paid to low-income elderly with poor self-perceived health.

Validation of the 7-item knee replacement patient education questionnaire (KR-PEQ-7), based on the 16-item knee osteoarthritis patient education questionnaire (KOPEQ)

Background

The aim of this study was to investigate the content validity including item reduction, construct validity and internal consistency of the existing 16-item Knee Osteoarthritis Patient Education Questionnaire. Former research had indicated that a reduction of items was necessary. Participants were patients with severe knee osteoarthritis who, prior to undergoing a knee replacement operation, participated routinely in a preoperative educational intervention.

Methods

A mixed method design was used. The first step was directed at the reduction in the number of items on the 16-item Knee Osteoarthritis Patient Education Questionnaire. Based on a priori hypotheses, this was followed by a cross-sectional validation study, performed to compare the resulting 7-item Knee Replacement Patient Education Questionnaire to a patient-testing Interview Protocol that was tailored to the same patient educational material. Additionally, the revised questionnaire was correlated with both the Short Test of Functional Health Literacy and the Mini-Mental State Examination score.

Results

A relatively high internal consistency was found for the 7-item Knee Replacement Patient Education Questionnaire, with a Cronbach’s alpha of 0.84 (SE: 0.036). Explanatory factor analysis showed no evidence against a one-factor model, with the first and second eigenvalues being 3.8 and 0.31, respectively. Bayesian Estimation of the correlation between the 7-item Knee Replacement Patient Education Questionnaire and the Interview Protocol was 0.78 (mode) (95% HPD 0.58–0.89).

Conclusions

The 7-item Knee Replacement Patient Education Questionnaire shows good psychometric properties and could provide valuable support to health professionals. It can provide valid feedback on how patients waiting for a knee replacement operation experience an applied patient education intervention. Further investigation is needed to assess the applicability of the 7-item Knee Replacement Patient Education Questionnaire to larger samples in different hospitals and countries.

A Pantheoretical Framework to Optimize Adherence to Healthy Lifestyle Behaviors and Medication Adherence: The Use of Personalized Approaches to Overcome Barriers and Optimize Facilitators to Achieve Adherence

Patient nonadherence to healthy lifestyle behaviors and medical treatments (like medication adherence) accounts for a significant portion of chronic disease burden. Despite the plethora of behavioral interventions to overcome key modifiable/nonmodifiable barriers and enable facilitators to adherence, short- and long-term adherence to healthy lifestyle behaviors and medical treatments is still poor. To optimize adherence, we aimed to provide a novel mobile health solution steeped in precision and personalized population health and a pantheoretical approach that increases the likelihood of adherence. We have described the stages of a pantheoretical approach utilizing tailoring, clustering/profiling, personalizing, and optimizing interventions/strategies to obtain adherence and highlight the minimal engineering needed to build such a solution.

Role of risk attitude and time preference in preventive aspirin use adherence

BACKGROUND

Poor adherence to medication that is taken chronically for the prevention of cardiovascular disease (CVD) continues to occur. Poor adherence is a primary barrier to treatment success and affects not only the patient but also the health care system.

OBJECTIVE

We aim to explore the impacts of risk attitudes and time preferences on the decisions of patients to begin and comply with aspirin therapy for CVD prevention.

METHODS

Three hundred fifty-seven patients who used low-dose aspirin for CVD prevention under the guidance of their doctors completed the survey. The risk attitudes and time preferences of the patients were elicited using a multiple price list experiment. Logistic regression models were used to examine the predictors of adherence to aspirin use.

RESULTS

Risk-seeking behaviours were significantly associated with both nonparticipation (P < .01) and lower compliance (P < .05) in patients. The coefficient for time preference was only significant at the 0.05 level for the decision to initiate aspirin use, which indicated that more impatient patients were less likely to begin with the use of aspirin. Forgetfulness in using aspirin on time and a lack of knowledge (as well as a lack of belief in the use of aspirin) could largely explain the poor adherence to aspirin therapy.

CONCLUSIONS

The identification of risk seekers and of those individuals who discount the future to a lesser degree may help providers to formulate tailored strategies to their patients, thus effectively enhancing their adherence to treatment.

Utility of medicines information leaflets in hypertensive care in a setting with low health literacy: A cross-sectional study

Introduction:

Higher levels of health literacy improve utilization of health information, medication adherence and outcomes. Few studies evaluate the utility of medicines information in hypertensive care in settings with low health literacy.

Aim:

To determine the level of health literacy and utility of medicines information leaflets (MILs) among hypertensive patients in public health care in Namibia.

Methods:

A hospital-based survey among hypertensive patients receiving care at a referral hospital in Namibia from the 8 June 2018 to 29 June 2018. Patient’s health literacy and utility of MIL were assessed using three literacy tools and a survey questionnaire. Quantitative data were analysed using descriptive statistics and qualitative thematic content analysis for factors associate with the utility of the MIL.

Results:

Of the 139 patients, 63% were female and the mean age was 45.7 (range: 19.0–84.0) years. Over 85.6% had of low literacy skills (Rapid Estimate of Literacy in Medicine (REALM) score <44, that is, unable to read simple health materials), 38.8% had positive Single Item Literacy Screener (SILS) scores (⩾2, require help to read medicines information) and 66.9% had inadequate skills for comprehension, appraisal and decision-making with regard to health information (Health Literacy Skills Instrument-Short Form (HLSI-SF) score <70%). The level of access to and utility of MIL were low, 32.4% and 34.6%, respectively. The main factors associated with poor utility of the MIL were low patient health literacy, lack of guidelines on the use of MIL and MIL written in non-native languages.

Conclusion:

Low rates of health literacy and utility of MIL were observed among hypertensive patients in Namibia. The integration of health literacy programmes, and MIL guidelines are needed to promote utility of medicine information and improve medication adherence.

Exploring the barriers and facilitators for the use of digital health technologies for the management of COPD: a qualitative study of clinician perceptions

BACKGROUND

Digital health technology (DHT) promises to support patients and healthcare professionals (HCPs) to optimize the management of chronic obstructive pulmonary disease (COPD). However, there is a lack of evidence demonstrating the effectiveness of DHT for the management of COPD. One reason for this is the lack of user-involvement in the development of DHT interventions in COPD meaning their needs and preferences are rarely accounted for in the design phase. Although HCP adoption issues have been identified in relation to DHT, little is known about the challenges perceived by HCPs providing care to COPD patients. Therefore, this study aims to qualitatively explore the barriers and facilitators HCPs perceive for the use of DHT in the management of COPD.

METHODS

Participants (n = 32) were recruited using snowball sampling from two university hospitals and several general practitioner clinics. A semi-structured interview was conducted with each participant. NVivo 12 software was used to complete thematic analysis on the data.

RESULTS

Themes identified include: data quality; evidence-based care; resource constraints; and digital literacy presented as barriers; and facilitators include the following themes: digital health training and education; improving HCP digital literacy; and Personalized prescribing. Patient-centered approaches, such as pulmonary rehabilitation and shared decision-making were suggested as implementation strategies to ease the adoption of digital health for the management of COPD.

CONCLUSION

These findings contribute new insights about the needs and preferences of HCPs working in COPD regarding DHT. The findings can be used to help mitigate user-experience issues by informing the design of person-centered implementation and adoption strategies for future digital health interventions in COPD.

Diabetes, Therapeutic Inertia, and Patients' Medication Experience

Factors contributing to therapeutic inertia related to patients' medication experiences include concerns about side effects and out-of-pocket costs, stigmatization for having diabetes, confusion about frequent changes in evidence-based guidelines, low health literacy, and social determinants of health. A variety of solutions to this multifactorial problem may be necessary, including integrating pharmacists into interprofessional care teams, using medication refill synchronization programs, maximizing time with patients to discuss fears and concerns, being cognizant of language used to discuss diabetes-related topics, and avoiding stigmatizing patients. Managing diabetes successfully is a team effort, and the full commitment of all team members (including patients) is required to achieve desired outcomes through an individualized approach.

Partner presence in the emergency department and adherence to daily cardiovascular medications in patients evaluated for acute coronary syndrome

Stressful health situations may compromise spouses'/partners' ability to provide patients with support. We tested whether partner status/partner presence in the emergency department (ED) were associated with patients' adherence to daily cardiovascular medications and whether effects differed by age/gender. Participants were 189 patients evaluated for acute coronary syndrome at an urban academic ED (M_Age = 62.18; 57.1% male; 58.7% Hispanic). Participants self-reported partner status/partner presence. Medication adherence was measured using an electronic pillcap. For male patients, having a partner was associated with increased adherence in the first month post-discharge, OR 1.94, p < .001, but having a partner present in the ED was associated with lower adherence, OR 0.33, p < .001. The opposite effect was evident for female patients. Partner status/partner presence in the ED are associated with medication adherence during the first month post discharge, with opposing effects for male and female patients.

Psychometric Evaluation of Chinese Version of Adherence to Refills and Medications Scale (ARMS) and Blood-Pressure Control Among Elderly with Hypertension

OBJECTIVE

This study aimed to develop the ARMS-C and test its psychometric properties in hypertensive patients, to assess the level of medication adherence and to identify associated predictors for medication adherence and blood-pressure control among Chinese hypertensive patients.

METHODS

Hypertensive elderly who met inclusion criteria were recruited from an aged-care facility in Henan Province between January 2019 and July 2019. The patients completed the adapted ARMS-C. The scale's factor structure, internal consistency, and construct validity were tested.

RESULTS

Good internal consistency (Cronbach's α=0.89) and test-retest reliability (r=0.86, p<0.01) were obtained. Item-total correlation coefficients for the ten-item ARMS-C were 0.505-0.801. Factor analysis of construct validity identified two factors, explaining a total variance of 63.3%. Binary regression showed that patients with scores at level 2 (≤20 ARMS-10 scores <30) were six times as likely to have blood pressure uncontrolled as those at level 1 (ARMS-10 scores <20, OR 6.6, 95% CI 1.7-25.1; p=0.006), and patients with scores at level 3 (ARMS-10 scores >30) were 115 times as likely to have blood pressure uncontrolled as those at level 1 (ARMS-10 scores <20,OR 115, 95% CI 9-1,470; p=0).

CONCLUSION

The ten-item ARMS-C is a reliable and valid self-reporting screening tool for adherence to medication and refills in elderly hypertensive Chinese patients.

Associations Between Health Literacy and Medication Self-Management Among Community Health Center Patients with Uncontrolled Hypertension

PURPOSE

Examine associations between health literacy and several medication self-management constructs among a population of adults with uncontrolled hypertension.

PATIENTS AND METHODS

Cross-sectional study of health center patients from the Chicago area with uncontrolled hypertension enrolled between April 2012 and February 2015. Medication self-management constructs-applied to hypertension medications, chronic condition medications and all medications-included: 1) medication reconciliation, 2) knowledge of drug indications, 3) understanding instructions and dosing, and 4) self-reported adherence over 4 days (no missed doses). We determined associations between health literacy and self-management outcomes using multivariable generalized linear regression.

RESULTS

There were 1460 patients who completed screening interviews; 62.9% enrolled and had complete baseline data collected, and were included in the analysis. Of 919 participants, 47.4% had likely limited (low), 33.2% possibly limited, and 19.4% likely adequate health literacy. Compared to participants with likely adequate health literacy, participants with low health literacy were less likely to have chronic medications reconciled (18.0% versus 29.6%, p=0.007), know indications for chronic medications (64.1% versus 83.1%, p<0.001), and demonstrate understanding of instructions and dosing (68.1% versus 82.9%, p=0.001). Self-reported adherence to hypertension medications was higher among the low health literacy group (65.6% versus 56.0%, p=0.010). In multivariable models, health literacy was strongly associated with knowledge of drug indications, and understanding of instructions and dosing.

CONCLUSION

Low health literacy was associated with worse medication self-management in several domains. However, non-adherence was greatest in the most health literate in unadjusted analysis. Among a population of patients with uncontrolled hypertension, the drivers of poor control may vary by health literacy.

Medical Drama Viewing and Medical Trust: A Moderated Mediation Approach

This study investigates the relationship between medical drama viewing and medical trust, applying the cultivation theory and using a moderated mediation approach. A multigroup Structural Equation Modeling analysis of survey data on 983 U.S. adults indicates that exposure to medical dramas is positively associated with perceived realism of medical dramas, which in turn is positively associated with trust in physicians in medical dramas, and this trust in physicians in medical dramas is positively associated with trust in physicians in the real world. The study suggests that perceived realism of and trust in physicians in medical dramas mediate the relationship between medical drama viewing and medical trust, with health literacy moderating this cultivation process. Implications and future research directions are discussed.

Health literacy in persons at risk of and patients with coronary heart disease: A systematic review

BACKGROUND

Health literacy (HL) plays a crucial role in the maintenance and improvement of individual health. Empirical findings highlight the relation between a person's HL-level and clinical outcomes. However, the role of HL in persons at risk for coronary heart disease (CHD) and patients with CHD has not been researched conclusively.

OBJECTIVE

The aim of this study was to review systematically the current evidence on HL, its dimensions (access to, understanding, appraisal and apply of health-related information), and its important influencing factors, with regard to CHD risk.

METHOD

We used a mixed-methods approach. Eligible articles needed to employ a validated tool for HL or mention the concept and at least one of its dimensions. After the screening process, 14 quantitative and 27 qualitative studies were included and referred to one or more dimensions of HL. Six observational studies measured HL with a validated tool.

RESULTS

Findings suggest that patients with lower HL feel less capable to perform lifestyle changes, exhibit fewer proactive coping behaviors, are more likely to deny CHD, are generally older, are less often employed, have lower educational levels and lower socioeconomic status, experience faster physical decline, and use the healthcare system less, compared to patients with higher HL. Barriers to HL include inadequate provision of information by health providers, lack of awareness of the risk factors for CHD, perceived impairment of quality of life due to lifestyle changes, and negative experiences with the healthcare system. Facilitators include a good patient-physician relationship based on good communicative competences of health providers.

CONCLUSIONS

The concept of HL yields a promising potential to understand the process from obtaining information to actual health behavior change, and the results clearly indicate the need for more systematic research on HL in CHD patients and persons at risk.

Impact of number of medications and age on adherence to antihypertensive medications: A nationwide population-based study

This study tried to investigate the effects of number of medications and age on antihypertensive medication adherence in a real-world setting using a nationwide representative cohort.We obtained data from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) of Korea, which is a sample of 2.2% (N = 1,048,061) of total population (N = 46,605,433). Patients aged 20 years or older (N = 150,550) who took antihypertensive medications for at least 1 year were selected. Medication possession ratio (MPR) was used for measuring adherence. The subjects were divided into 5 subgroups according to total number of medications: 1-2, 3-4, 5-6, 7-8, and 9 or more. The mean age and the mean number of medications were 60.3 ± 12.6 years and 4.1 ± 2.2, respectively. The mean MPR was 80.4 ± 23.9%, and 66.9% (N = 100,645) of total subjects were adherent (MPR ≥ 80%). The overall tendency of antihypertensive medication adherence according to the total number of medications displayed an inverted U-shape with a peak at 3-4 drugs. Adherence consistently increased as the age increased until age 69 and started to decrease from age 70. The proportion of adherent patients (MPR ≥ 80%) according to the total number of medications also showed an inverted U-shape with a peak at 3-4 drugs. When the same number of drugs was taken, the proportion of adherent patients according to age featured an inverted U- shape with a peak at 60 to 69 years. Patients taking 9 or more total drugs had the overall odds ratio (95% CI) of non-adherence (MPR < 80%) with 1.17 (1.11-1.24) compared with those taking 1 to 8 total drugs and the odds ratios in the age subgroups of 40 to 49, 50 to 59, 60 to 69 years were 1.57 (1.31-1.87), 1.21 (1.08-1.36), and 1.14 (1.04-1.25), respectively (P < .05).Association between age, total number of medications, and antihypertensive adherence displayed an inverted U-shape with a peak at 3 to 4 total medications and at age 60 to 69 years. When the total number of drugs was 9 or more, adherence decreased prominently, regardless of age.

Anticoagulation adherence and its associated factors in patients with atrial fibrillation: a cross-sectional study

OBJECTIVE

To investigate anticoagulant adherence and its associated factors, including demographics, clinical variables, atrial fibrillation (AF) severity, knowledge, satisfaction with services, perceived barriers, perceived benefits, symptom severity and self-efficacy in patients with AF.

DESIGN

This is a cross-sectional study.

PARTICIPANTS AND SETTING

A convenient sample of patients with AF were recruited from cardiology clinics of two teaching hospitals in Taiwan.

MEASURES

Data were collected using the study questionnaires, including the AF-related symptom subscale of the AF Severity Scale, the Knowledge of Warfarin Anticoagulation Treatment Scale, the Satisfaction Scale about Service and Warfarin Treatment, the perceived benefits subscale of the Beliefs about Anticoagulation Survey, the Concerns about Anticoagulation Therapy Scale, The Self-efficacy for Appropriate Medication Use Scale and the short-form Adherence to Refills and Medications Scale.

RESULTS

A total of 151 patients with AF participated in the study; 53 treated with warfarin and 98 treated with novel oral anticoagulants (NOACs). The difference in adherence to warfarin (mean=8.6; SD=1.6) and NOACs (mean=8.9; SD=2.0) was statistically insignificant. Multiple linear regression analysis showed that perceived barriers (β=0.18, p=0.017) and self-efficacy (β=-0.48, p<0.001) were significant predictors of anticoagulation adherence. For every 1-unit increase in the perceived barriers, there will be a 0.18-unit increase in the adherence to anticoagulation therapy. For every 1-unit increase in the self-efficacy, there will be a 0.48-unit decrease in the adherence to anticoagulation therapy. Perceived barriers and self-efficacy collectively explained 34.0% of the variance in adherence to anticoagulation therapy (F_(2,149)=38.11, p<0.001).

CONCLUSION

We found no better adherence to NOACs compared with warfarin. Patients with greater self-efficacy and perceived fewer barriers showed better adherence to anticoagulation therapy.
