Patient trust, quality communication, and medication adherence in rheumatoid arthritis patients highly affected by social determinants of health

INTRODUCTION

Because medication adherence is essential to the management of rheumatoid arthritis (RA), identifying (1) subgroups at high risk for low medication adherence and (2) modifiable factors potentially contributing to low adherence can impact patient outcomes. This study aims to describe the relationships between anxiety, trust in the provider, quality patient-provider communication, fatigue, RA knowledge, adverse medication effects, disease activity, RA medications, disease duration, patient satisfaction, and medication intolerance and cluster factors to differentiate RA-patient subgroups.

METHODS

This observational study used correlation analysis, linear regression, and cluster analysis with determination decisions based on Schwarz's Bayesian Criterion.

RESULTS

Medication adherence was higher in non-Hispanic, White participants, inversely correlated with disease activity and pain intensity, and positively correlated with trust in the provider. Patient satisfaction was higher among those with a shorter time since diagnosis, and was negatively associated with disease activity, pain intensity and interference, fatigue, and anxiety. It was positively associated with RA knowledge, trust in provider and quality of patient-provider communication. Medication intolerance differed by disease duration and was positively correlated with disease activity, pain interference, and fatigue. Of the two clusters, Cluster 1 participants had greater medication adherence and patient satisfaction, and lower medication intolerance. They were of higher income, employed, and non-Hispanic, White persons with a shorter disease duration and lower perceived pain intensity/interference, fatigue, and anxiety. They were more knowledgeable about RA with higher trust in their provider and perceived quality of patient-provider communication.

DISCUSSION/CONCLUSION

A low medication adherence RA-patient subgroup-highly affected by social determinants of health and with unique relational and clinical characteristics was identified.

Do syndemic conditions predict HIV medication adherence among urban African American men?

Much progress has been made in advancing antiretroviral (ART) adherence, yet disparities remain. To explore relationships of syndemic conditions - co-occurring health conditions caused by combinations of biological, social, and structural factors - to ART adherence among African American men, we used data from longitudinal assessments of 302 African American men enrolled in a study designed to increase physical activity and healthy eating. Syndemic conditions included alcohol dependency, drug dependency, depression, post-traumatic stress disorder, and unstable housing. A syndemic conditions variable was operationalized to indicate the presence of 0-5 conditions. About 55% of participants had 1 or more syndemic conditions. Age and marriage were positively associated with ART adherence, whereas number of syndemic conditions was negatively associated with adherence during the 12-month period. The interaction of being married and the syndemic conditions variable significantly predicted greater adherence. Similarly, the interaction of more education and the syndemic conditions variable predicted greater adherence. In multiple regression models, the syndemic conditions variable remained significant (-0.018) in predicting adherence; however, there was no significant interaction among the 5 conditions. This study lends evidence to syndemics literature indicating deleterious consequences of negative life experiences on health outcomes.

National surveillance using a clinical quality indicator for prolonged antipsychotic use among older Australians with dementia who access aged care services

OBJECTIVES

Dementia guidelines recommend antipsychotics are only used for behavioral and psychological symptoms when non-drug interventions fail, and to regularly review use. Population-level clinical quality indicators (CQIs) for dementia care in permanent residential aged care (PRAC) typically monitor prevalence of antipsychotic use but not prolonged use. This study aimed to develop a CQI for antipsychotic use >90 days and examine trends, associated factors, and variation in CQI incidence; and examine duration of the first episode of use among individuals with dementia accessing home care packages (HCPs) or PRAC.

METHODS

Retrospective cohort study, including older individuals with dementia who accessed HCPs (n = 50,257) or PRAC (n = 250,196). Trends in annual CQI incidence (2011-12 to 2015-16) and associated factors were determined using Poisson regression. Funnel plots examined geographical and facility variation. Time to antipsychotic discontinuation was estimated among new antipsychotic users accessing HCP (n = 2367) and PRAC (n = 15,597) using the cumulative incidence function.

RESULTS

Between 2011-12 and 2015-16, antipsychotic use for >90 days decreased in HCP recipients from 10.7% (95% CI 10.2-11.1) to 10.1% (95% CI 9.6-10.5, adjusted incidence rate ratio (aIRR) 0.97 (95% CI 0.95-0.98)), and in PRAC residents from 24.5% (95% CI 24.2-24.7) to 21.8% (95% CI 21.5-22.0, aIRR 0.97 (95% CI 0.96-0.98)). Prior antipsychotic use (both cohorts) and being male and greater socioeconomic disadvantage (PRAC cohort) were associated with higher CQI incidence. Little geographical/facility variation was observed. Median treatment duration in HCP and PRAC was 334 (interquartile range [IQR] 108-958) and 555 (IQR 197-1239) days, respectively.

CONCLUSIONS

While small decreases in antipsychotic use >90 days were observed between 2011-12 and 2015-16, findings suggest antipsychotic use among aged care recipients with dementia can be further minimized.

Effectiveness of motivational interviewing on medication adherence for the prevention of recurrent stroke or transient ischemic attack: Systematic review of randomized controlled trials

BACKGROUND AND PURPOSE

This systematic review examines the effectiveness of motivational interviewing (MI) on medication adherence for preventing recurrent stroke and transient ischemic attack (TIA).

METHODS

MEDLINE (via PubMed), CINAHL, PsycINFO, CENTRAL, and ClinicalTrials.gov were searched from inception to 12 June 2023. Randomized controlled trials comparing MI with usual care or interventions without MI in participants with any stroke type were identified and summarized descriptively. Primary outcome was medication adherence. Secondary outcomes were quality of life (QoL) and different clinical outcomes. We assessed risk of bias with RoB 2 (revised Cochrane risk-of-bias tool) and intervention complexity with the iCAT_SR (intervention Complexity Assessment Tool for Systematic Reviews).

RESULTS

We screened 691 records for eligibility and included four studies published in five articles. The studies included a total of 2751 participants, and three were multicentric. Three studies had a high risk of bias, and interventions varied in complexity. Two studies found significantly improved medication adherence, one at 9 (96.9% vs. 88.2%, risk ratio = 1.098, 95% confidence interval = 1.03-1.17) and one at 12 months (97.0% vs. 95.0%, p = 0.026), but not at other time points, whereas two other studies reported no significant changes. No significant differences were found in QoL or clinical outcomes.

CONCLUSIONS

Evidence on MI appears inconclusive for improving medication adherence for recurrent stroke and TIA prevention, with no benefits on QoL and clinical outcomes. There is a need for robustly designed studies and process evaluations of MI as a complex intervention for people with stroke.

Effects of a Planned Web-Based Educational Intervention Based on the Health Belief Model for Patients With Ischemic Stroke in Promoting Secondary Prevention During the COVID-19 Lockdown in China: Quasi-Experimental Study

Background

Some common modified vascular risk factors remain poorly controlled among stroke survivors, and educational programs may help improve these conditions.

Objective

This study aimed to evaluate the effect of a planned web-based educational intervention based on the health belief model (HBM) in promoting secondary prevention among patients with ischemic stroke.

Methods

An evaluation-blinded quasi-experimental trial with a historical control group was conducted. Patients admitted from March to June 2020 were assigned to the historical control group, and patients admitted from July to October 2020 were assigned to the intervention group. The control group received routine health management. The intervention group received 6 additional sessions based on the HBM via Tencent Meeting, an audio and video conferencing application, within 3 months after discharge. Sessions were held every 2 weeks, with each session lasting approximately 40 minutes. These sessions were conducted in small groups, with about 8 to 10 people in each group. The primary outcomes were changes in blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), hemoglobin A1c (HbA1c), and the proportion of patients achieving the treatment target. The secondary outcomes were medication adherence, assessed with the Morisky Medicine Adherence Scale (MMAS), and disability, assessed with the modified Rankin scale.

Results

In total, 315 patients experiencing their first-ever stroke were analyzed. More patients in the intervention group had controlled BP (41.9% vs 28.4%; adjusted odds ratio [aOR] 1.93; P=.01), LDL-C (83.1% vs 67.7%; aOR 2.66; P=.001), and HbA1c (91.9% vs 83.9%; aOR: 3.37; P=.04) levels as well as a significant postintervention decrease in the systolic BP (adjusted β -3.94; P=.02), LDL-C (adjusted β -0.21; P=.008), and HbA1c (adjusted β -0.27; P<.001), compared with control groups. Significant between-group differences were observed in medication adherence (79.4% vs 63.2%; aOR 2.31; P=.002) but not in favorable functional outcomes.

Conclusions

A web-based education program based on the HBM may be more effective than current methods used to educate patients having strokes on optimal vascular risk factors and medication adherence.

Adherence, persistence and treatment switching in psoriasis

Aim: This study aims to investigate drug utilization patterns in the treatment of psoriasis (PsO) from 1 to 5 years in a real-life setting with Adalimumab (Ada), Etanercept (Eta), Ustekinumab (Ust), Golimumab (Gol), Ixekizumab (Ixe), Secukinumab (Sec) and Apremilast (Apr). Materials & methods: Data from an observational study were used to calculate adherence using the Proportion of Days Covered (PDC) method and persistence. Results & conclusion: Treatment adherence was found to be good for all the drugs studied across all years of analysis, while persistence was suboptimal, showing a marked decrease from the third year of study onward. In the treatment of PsO, greater attention needs to be paid to treatment persistence.

An exploratory study of community violence and HIV care engagement among Black gay and bisexual men

This study examined the relationship between exposure to community violence and HIV care engagement among 107 Black gay or bisexual men living with HIV in Chicago. Measures assessed the importance of demographic covariates (age, annual income, health insurance status, and years living with HIV), community violence exposures, mental health, social support, in explaining variations in missed doses of antiretroviral therapy (ART) medication and missed HIV care appointments. Results showed that participants who reported higher rates of exposure to community violence were two times more likely to have missed ART doses and HIV care appointments. Participants who reported depression scores were two times more likely to have greater non-ART adherence. Finally, older participants were more likely to report fewer missed ART doses. More research is needed to clarify the mechanisms between age or depression and ART adherence given community violence exposure. Health care providers should screen for depression when attempting to promote better ART adherence and keeping HIV care appointments for Black gay and bisexual men living with HIV. Younger Black gay and bisexual men living with HIV may be more vulnerable than older men for missed ART doses and may require additional screening and follow-up.

The analysis of factors affecting medication adherence in patients with myasthenia gravis: a cross-sectional study

Background

Clinically, patients with myasthenia gravis are generally treated with drugs to improve their physical condition, and poor medication adherence can hinder their recovery. Many studies have shown the importance of medication adherence for effective treatment. Various factors may affect a patient's medication adherence; however, studies concerning medication adherence in patients with myasthenia gravis are rare.

Objectives

This study aimed to identify the factors related to medication adherence in patients with myasthenia gravis, and determine the possibility of predicting medication adherence.

Methods

This cross-sectional observational study was conducted among inpatients and outpatients with myasthenia gravis of the First Affiliated Hospital of Guangzhou University of Chinese Medicine in China. Data on patient demographics, disease-related characteristics, and medical treatment were collected. We evaluated medication adherence of the patients using the Morisky Medication Adherence Scale-8, Beliefs about Medicines Questionnaire, and the Self-efficacy for Appropriate Medication Use Scale.

Results

We distributed 200 questionnaires and finally retrieved 198 valid questionnaires. A total of 139 (70.2%) women participated in this study, and 81 (40.9%) among the 198 participants were aged 40-59 years. In total, 103 (52.0%) participants exhibited bad adherence to pharmacological treatment, and factors such as taking medication irregularly [odds ratio (OR) = 0.242, 95% CI = 0.093-0.627], the necessity of taking medicine (OR = 1.286, 95% CI = 1.142-1.449), the concerns of taking medicine (OR = 0.890, 95% CI = 0.801-0.988), and the self-efficacy for taking medications under difficult circumstances (OR = 1.194, 95% CI = 1.026-1.389) had statistically significant impacts on medication adherence.

Conclusion

Our study shows that taking medication irregularly and concerns of taking medicine are the risk factors for medication adherence. Meanwhile, the necessity of talking medicine and self-efficacy for taking medications under difficult circumstances are the protective factors for medication adherence. Our findings can help medical staff to enhance patients' medication adherence by informing patients necessary medical knowledge, emphasizing the necessity for medication, relieving patients' concerns regarding medication, and improving the self-efficacy for taking medications under difficult circumstances.

A randomized controlled trial of medication adherence and management of risk factors for secondary prevention of stroke (MaMoRS) using a smartphone-based application

BACKGROUND

There are little data on the use of smartphone-based applications for medication adherence and risk-factor control for the secondary prevention of stroke in low-and-middle-income countries (LMICs).

AIMS

The aim was to determine whether a smartphone-based app improved medication adherence, risk-factor control, and provided health education to stroke survivors for lifestyle and behavioral modifications.

METHODS

An unblinded, single-center randomized controlled double arm trial with 1:1 allocation among stroke survivors was performed in South India. The primary outcome was medication adherence, with co-primary outcomes of lifestyle and behavioral factors and control of vascular risk factors, at 3 and 6 months.

RESULTS

Among 351 stroke survivors screened, 209 were recruited. The mean (standard deviation (SD)) age of the intervention (n = 105) group was 60 (12) years and that of the control (n = 104) group was 60 (10) years. In the primary outcome, mean medication adherence significantly improved in the intervention group with a between group difference of 0.735 (95% confidence interval (CI) = 0.419 to 1.050), p < 0.001. Being in intervention group (OR = 4.5; 95% CI = 2.3 to 8.9), stroke recurrence (OR = 3.3 (95% CI = 1.9 to 7.8)), and regular physician visits (OR = 2.1; 95% CI = 1.0 to 4.4) were significant predictors of good medication adherence. Considering the co-primary outcomes, compared to the control group, participants in the intervention group had a greater improvement in self-reported healthy diet intake (p = 0.003), intake of fruits (p = 0.005), and were physically more active (p = 0.001). At 6 months, mean fasting blood sugar (p = 0.005) and high-density lipoprotein cholesterol higher (p = 0.024) in the intervention group.

CONCLUSIONS

The use of a mobile app is an effective method to improve medication adherence and risk-factor control in stroke survivors and is feasible in LMICs like India.

Factors Affecting the Level of Adherence to Hypertension Medications: A Cross-Sectional Study Using the Hill-Bone Questionnaire

Background

The adherence to antihypertensive therapy plays a significant role in determining the clinical outcomes of hypertension. We aim to evaluate the level of adherence to antihypertensive medications among patients and to assess the effect of different sociodemographic factors on the level of adherence using the Hill-Bone scale for indirect assessment.

Methodology

In this cross-sectional study, we utilized a validated, face-to-face interview questionnaire to collect data on sociodemographic characteristics, participants' attitudes, and disease knowledge. The Hill-Bone questionnaire was employed to assess treatment adherence. The statistical analysis was conducted using SPSS version 28.0, where mean, standard deviation, and range were utilized for variability analysis.

Results

A total of 390 patients were included in this study. The sample comprised 56.9% of females and 56.4% of participants aged 60 years or older. Approximately 80% of participants were currently married, and 46.7% had a higher education level. The average Hill-Bone CHBPTS score was 21.23± 4.95 and indicated good adherence in 63.8% of participants. The findings showed that several factors were significantly associated with higher adherence rates, including older age (COR = 3.41, 95% CI = 1.10-10.54, p = 0.03), higher educational level (COR = 1.72, 95% CI = 1.05-2.83, p = 0.03), regular blood pressure monitoring (COR = 1.90, 95% CI = 1.10-3.30, p = 0.03), and knowledge about their medications (COR = 2.12, 95% CI = 1.14-3.94, p = 0.02).

Conclusion

The medication adherence within our population falls below the desired level. Enhanced counselling and further research are necessary to identify additional factors influencing adherence and develop effective strategies for promoting adherence to antihypertensive medications.

Improving Medication Adherence Levels in Inflammatory Bowel Disease (IBD) Patients: A Narrative Evidence-Based Review

Inflammatory bowel disease (IBD) management is typified by a long-term medication regimen which can comprise multiple medications prescribed in different combinations, doses, frequencies, and with various administration routes. This complexity can make medication adherence (MA) - patients taking their medications per the prescription - for patients with IBD a challenge. The research corpus contains diverse interventions aimed at improving MA in patients with IBD. Therefore, to condense the evidenced strategies for ease of reference, this narrative evidence-based review broadly outlines the patient-level interventions reported. The interventions are grouped as educational, behavioural, cognitive-behavioural, and multicomponent. They, however, present mixed results as to their efficacy at improving MA, with those employing combined approaches being the most promising. This reflects the reality that MA is impacted by multiple factors encompassing those pertaining to the patient, disease, therapy, patients' socioeconomic status, and health system. Hence, the most ideal interventions would likely be multifaceted patient-level interventions alongside policy/system-level strategies, to maximise the potential for successfully improving patients' MA. These findings might have been impacted by the heterogeneity of the studies in terms of the method of MA assessment, duration of interventions, and more besides.

Structural Equation Modelling to Identify Psychometric Determinants of Medication Adherence in a Survey of Kidney Dialysis Patients

Purpose

Medication non-adherence in dialysis patients is associated with increased mortality and higher healthcare costs. We assessed whether medication adherence is influenced by specific psychometric constructs measuring beliefs about the necessity for medication and concerns about them. We also tested whether medication knowledge, health literacy, and illness perceptions influenced this relationship.

Patients and Methods

This study is based on data from a cross-sectional in-person questionnaire, administered to a random sample of all adult dialysis patients at a teaching hospital. The main outcome was self-assessed medication adherence (8-Item Morisky Medication Adherence Scale). The predictors were: concerns about medications and necessity for medication (Beliefs About Medication Questionnaire); health literacy; medication knowledge (Medication Knowledge Evaluation Tool); cognitive, emotional, and comprehensibility Illness perceptions (Brief Illness Perception Questionnaire). Path analysis was performed using structural equations in both covariance and variance-based models.

Results

Necessity for medication increased (standardized path coefficient [β] 0.30 [95% CI 0.05, 0.54]) and concerns about medication decreased (standardized β -0.33 [-0.57, -0.09]) medication adherence, explaining most of the variance in outcome (r2=0.95). Medication knowledge and cognitive illness perceptions had no effects on medication adherence, either directly or indirectly. Higher health literacy, greater illness comprehension, and a more positive emotional view of their illness had medium-to-large sized effects in increasing medication adherence. These were indirect rather and direct effects mediated by decreases in concerns about medications (standardized β respectively -0.40 [-0.63,-0.16], -0.60 [-0.85, -0.34], -0.33 [-0.52, -0.13]).

Conclusion

Interventions that reduce patients' concerns about their medications are likely to improve adherence, rather than interventions that increase patients' perceived necessity for medication. Improving patients' general health literacy and facilitating a better understanding and more positive perception of the illness can probably achieve this. Our study is potentially limited by a lack of generalizability outside of the population and setting in which it was conducted.

Latent Profile Analysis of Medication Beliefs in Patients with Type 2 Diabetes in the Hospital-Home Transition and Comparison with Medication Adherence

Background

The treatment of Type 2 Diabetes Mellitus (T2DM) is a protracted and arduous process. Medication, being a universally crucial therapeutic measure, underscores the significance of medication adherence in managing the disease effectively. Medication beliefs have emerged as a significant predictor of adherence, attracting considerable scholarly attention in recent years. However, there remains a paucity of research utilizing individual-centered approaches to explore medication beliefs among the T2DM population during the hospital-home transition, leaving the relationship between these beliefs and medication adherence unclear.

Purpose

To investigate latent categories of medication beliefs among patients with T2DM during the transition from hospital to home, and to analyze variations in medication adherence across these categories of patients.

Patients and methods

Between August 2022 and September 2023, this study selected 304 patients with a pre-discharge diagnosis of T2DM as study subjects from a tertiary hospital in Dongguan City. The patients' profiles were assessed comprehensively via the Sociodemographic and Clinical Characteristics Questionnaire, alongside the Chinese version of Beliefs about Medicines Questionnaire-Specific and Morisky Medication Adherence Scale-8. The present study conducted latent profile analysis using Mplus 7.4 software and analyzed the influencing factors of different medication belief categories and their differences in medication adherence using SPSS 26.0 software.

Results

The medication beliefs of 304 patients were rated at 3.36±5.24 points, while medication adherence scored 6.23±1.56 points. The medication beliefs were classified into four categories: moderate necessity - low to moderate concern group (40.13%), high necessity - low concern group (9.54%), moderate necessity - moderate to high concern group (19.08%), and moderate necessity - high concern group (31.25%). Age, monthly per capita household income, and place of residence emerged as influential factors for the four categories. Moreover, the disparity in medication adherence among these categories demonstrated statistical significance (P < 0.001).

Conclusion

The medication beliefs of patients were classified into four distinct categories, and variations in medication adherence were evident across these categories. The high necessity - low concern group demonstrated the highest medication adherence scores, while the moderate necessity - high concern group exhibited the lowest scores. Healthcare providers are advised to tailor personalized medication belief enhancement programs based on patients' homogeneous beliefs, addressing specific issues encountered by each category. This approach aims to ensure optimal medication adherence across diverse medical and social environments, effectively improving patient prognosis and enhancing quality of life.

Validation of an Inhaled Therapy Beliefs Questionnaire in Patients with Chronic Obstructive Pulmonary Disease

Background: To carry out a validation questionnaire that assesses beliefs about inhaled treatments in patients with chronic obstructive pulmonary disease (COPD), as knowing patients' beliefs could help to improve medication adherence and health outcomes. Methods: We evaluated data from 260 COPD patients from electronic medical record databases from five primary healthcare centers, in a descriptive, cross-sectional study with a sample size calculated for a 10-item questionnaire, with an estimated Cronbach's alpha of 0.70 and a 95% confidence level. Study participants were selected via systematic random sampling. Variables: Ten-item Inhaled Therapy Beliefs Questionnaire, CCTI-Questionnaire v.2.0, time for completion, age, sex, educational level, spirometry severity (GOLD criteria), exacerbations (previous year), characteristics of inhaled treatment, and smoking habit. A two-year follow-up in a subsample of 77 patients from one health center was utilized. The Morisky-Green test, pharmacy dispensing data, test-retest (kappa coefficient), and an exploratory analysis of the adherence-belief relationship (ji-squared) were measured. Results: The 10-item questionnaire showed good viability (3 min completion time) when performed face-to-face or telephonically; its psychometric properties were acceptable, with an internal consistency (Cronbach's alpha) score of 0.613. Three factors explained 47.58% of the total variance (p < 0.0001): use (factor 1), effects (factor 2), and objectives (factor 3) of inhalers. The two-year follow-up ultimately considered 58 out of the 77 patients (10 deceased, 4 unlocated, 2 mistakes, 2 no inhaled treatment, and 1 withdrawal). Non-adherence was 48.3% in terms of the Morisky-Green test; 31% in terms of pharmacy dispensing data; and 40.4% considering both methods. There was low test-retest reliability, indicated by items 4, 8, and 9 of the CCTI-Questionnaire (Kappa = 0.4, 0.26, and 0.34; p-value < 0.0001, 0.008, and 0.001, respectively). There was mild correlation between beliefs and adherence. Conclusions: The ten-item CCTI-Questionnaire v.2.0 demonstrated acceptable psychometric properties regarding feasibility, reliability, and content validity.

Association between Visit Frequency, Continuity of Care, and Pharmacy Fill Adherence in Heart Failure Patients

BACKGROUND

Despite advances in medical therapy for heart failure with reduced ejection fraction (HFrEF), major gaps in medication adherence to guideline-directed medical therapies (GDMT) remain. Greater continuity of care may impact medication adherence and reduced hospitalizations.

METHODS

We conducted a cross-sectional study of adults with a diagnosis of HF and EF≤40% with ≥2 outpatient encounters between 1/1/2017 and 10/1/2021, prescribed ≥1 of the following GDMT: 1) Beta Blocker, 2) Angiotensin Converting Enzyme Inhibitor/Angiotensin Receptor Blocker/Angiotensin Receptor Neprilysin Inhibitor, 3) Mineralocorticoid Receptor Antagonist, 4) Sodium Glucose Cotransporter-2 Inhibitor. Continuity of care was calculated using the Bice-Boxerman Continuity of Care Index (COC) and the Usual Provider of Care (UPC) index, categorized by quantile. The primary outcome was adherence to GDMT, defined as average proportion of days covered ≥80% over one year. Secondary outcomes included all-cause and HF hospitalization at 1-year. We performed multivariable logistic regression analyses adjusted for demographics, insurance status, comorbidity index, number of visits and neighborhood SES index.

RESULTS

Overall, 3,971 individuals were included (mean age 72 years (SD 14), 71% male, 66% White race). In adjusted analyses, compared to individuals in the highest COC quartile, individuals in the third COC quartile had higher odds of GDMT adherence (OR 1.26, 95% CI 1.03-1.53, p=0.024). UPC tertile was not associated with adherence (all p>0.05). Compared to the highest quantiles, the lowest UPC and COC quantiles had higher odds of all-cause (UPC: OR 1.53, 95% CI 1.23-1.91; COC: OR 2.54, 95% CI 1.94-3.34) and HF (UPC: OR 1.81, 95% CI 1.23-2.67; COC: OR 1.77, 95% CI 1.09-2.95) hospitalizations.

CONCLUSIONS

Continuity of care was not associated with GDMT adherence among patients with HFrEF but lower continuity of care was associated with increased all-cause and HF-hospitalizations.

Factors affecting medication adherence in patients using oral chemotherapy: A descriptive study

INTRODUCTION

The utilization of oral chemotherapy agents for cancer treatment has witnessed a steady rise in recent years. The pivotal determinant for the success of oral chemotherapy lies in the adherence of cancer patients to the prescribed treatment. This study aims to explore oral chemotherapy adherence and identify factors influencing medication adherence among cancer patients.

METHODS

A total of 103 cancer patients participated in this descriptive study. Data were collected using the Oral Chemotherapy Adherence Scale, the Turkish Translation of the Beliefs about Medicines Questionnaire (BMQ-T) and The Functional Living Index-Cancer.

RESULTS

Of the participants, 66% reported good adherence to oral chemotherapy. Key findings indicate that access to health services (β = -1.473, p = 0.009), cancer stage (β = -1.570, p = 0.015) and the BMQ-T subscale of General Overuse (β = .696, p = 0.041) were independent predictors of medication adherence.

CONCLUSION

The study observed medication non-adherence in one-third of patients undergoing oral chemotherapy. Primary contributors to non-adherence included difficulties in accessing health services, advanced cancer stage and the belief that drugs are over-recommended by doctors. These results underscore the need for a heightened focus on preventable factors, such as improving access to health services and addressing beliefs about drug overuse, to enhance medication adherence in patients receiving oral chemotherapy.

Frequency of missed doses and its effects on the regulation of glucose levels in patients with type 2 diabetes: A retrospective analysis

This study aimed to investigate the association between medication adherence to oral hypoglycemic agents (OHAs) and HbA1c levels in patients with type 2 diabetes mellitus (T2DM) for more than 48 weeks, as well as the factors affecting long-term adherence to OHAs. This retrospective study included 83 patients who had been receiving OHAs for T2DM for ≥48 weeks. Medication adherence values (MAVs) were calculated using the following formula: (total prescription days - prescription days of OHAs brought at admission)/(days from the initiation of OHAs to hospitalization). We assessed the association between HbA1c and MAVs using the Jonckheere-Terpstra test. Furthermore, we examined the association between patient- and medication-related factors and MAVs affecting HbA1c levels. Based on the results, MAVs were categorized as MAV ≤0.86 and MAV >0.86, and factors affecting MAVs were analyzed. Logistic regression analysis revealed that the total number of medications, the number of nonhypoglycemic agents, and a family history of diabetes were independent determinants of MAV ≤0.86 (P < .05). Multiple regression analyses indicated that the number of dosages per day and the timing of OHA administration at lunch were independent determinants of lower MAVs (P < .05). Our findings suggest that poor medication adherence is associated with elevated HbA1c levels in T2DM patients. Independent factors contributing to poor adherence include a lower number of prescribed medications, fewer nonhypoglycemic agents, no family history, a higher daily dosage frequency, and the administration of OHAs at lunch.

Medication non-adherence remains a significant challenge for adolescent heart transplant recipients. Building on the success of a pilot intervention study, herein we describe the protocol for a follow-up randomised control trial using mobile video directly observed therapy, featuring several innovations, to promote medication adherence in a multi-centre sample of adolescent heart transplant patients.

Access to a tailored mobile application enhances medication adherence among young users of antidepressants

Introduction

Patients' adherence to antidepressants is generally reported to be poor. This study examined whether users of selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs) enhance medication adherence following access to a mobile application (app) tailored for this patient group. The study addresses the implementation phase of medication adherence.

Methods

The study was a single group pre-post intervention design. Data were collected using the validated OsloMet Adherence-to-medication Survey tool (OMAS-37) before and after app access. Pre-app access survey (Survey 1) was conducted via social media and online newspapers, encompassing 445 SSRI/SNRI users aged 18 years and above. Post-app access survey (Survey 2) was sent to 103 SSRI/SNRI users from Survey 1. Wilcoxon Signed Rank Test compared pre- and post-intervention adherence measurements. Pearson's chi-square tests and Fisher's exact tests compared study population categories.

Results

Forty-two SSRI/SNRI users, median age 26 (IQR 17), 93% identifying as female, used the app while using the same antidepressant during the 2-month period between gaining access to the app and Survey 2. There was a statistically significant reduction in non-adherence score post-app access (z = 3.57, n = 42, p < 0.001) with medium effect size (r = 0.39), indicating enhanced adherence. Total non-adherence score decreased by 39% from pre-to post-access, and there was a 12% decrease in users scoring equivalent with poor adherence (score <2) post-access. Twenty-nine of 37 non-adherence causes improved, with three showing statistical significance. Of 42 responders, 50% (n = 21) indicated using the app one to two times, while 50% (n = 21) more than three times. Approximately 69% (n = 28) found it useful, and 43% (n = 18) felt safer in their use of antidepressants after access to the app. No significant preference was observed for the app over alternative sources of information.

Discussion

Enhanced medication adherence was observed among antidepressant users following access to the tailored app. Further studies are warranted to evaluate the app applicability to a broader range of antidepressants users or other patient groups, encompassing those in the initiation phase of medication adherence. The app is intended as an easily accessible supplement to the information and advice provided by prescribing physicians and dispensing pharmacists.

Temporal characteristics and associated factors of discontinuation and outcomes after percutaneous coronary intervention

Background: Medication adherence in patients after percutaneous coronary intervention (PCI) is suboptimal, and discontinuation is common. Information on the temporal characteristics and associated factors of discontinuation and outcomes after PCI is insufficient to improve medication adherence interventions. Methods: We conducted a single-center retrospective study of post-PCI patients by telephone survey and medical record extraction. Temporal characteristics and associated factors of discontinuation and outcomes were examined by survival curve analysis, Cox regression, or time-dependent Cox regression. Results: Discontinuation and major adverse cardiovascular events (MACE) after PCI had similar temporal characteristics, with the highest incidence in the first year, followed by a decline. Temporary discontinuation was associated with pre-PCI medication nonadherence (HR 1.63; 95% CI: 1.09-2.43), lack of medication necessity (HR 2.33; 95% CI: 1.44-3.78), economic difficulties (HR 2.09; 95% CI: 1.26-3.47), routine disruption (HR 2.09; 95% CI: 1.10-3.99), and emotional distress (HR 2.76; 95% CI: 1.50-5.09). Permanent discontinuation was associated with residence in rural areas (HR 4.18; 95% CI: 1.84-9.46) or small to medium-sized cities (HR 4.21; 95% CI: 1.82-9.73), lack of medication necessity (HR 10.60; 95% CI: 6.45-17.41), and side effects (HR 3.30; 95% CI: 1.94-5.62). The MACE after PCI was associated with pre-PCI hypertension (HR 1.42; 95% CI: 1.04-1.96), two coronary stents (HR 1.42; 95% CI: 1.01-1.99) or three coronary stents (HR 1.66; 95% CI: 1.11-2.49) compared to one coronary stent up to this PCI, and temporary discontinuation (≤60 months HR 2.18; 95% CI: 1.47-3.25; >60 months HR 8.82; 95% CI: 3.65-21.28). Conclusion: Discontinuation and MACE after PCI have similar temporal characteristics, temporary discontinuation and permanent discontinuation have different associated factors, and the former is associated with MACE. These findings may provide guidance for medication adherence interventions.

Co-Design, Development, and Evaluation of a Mobile Solution to Improve Medication Adherence in Cancer: Design Science Research Approach

BACKGROUND

Medication nonadherence negatively impacts the health outcomes of people with cancer as well as health care costs. Digital technologies present opportunities to address this health issue. However, there is limited evidence on how to develop digital interventions that meet the needs of people with cancer, are perceived as useful, and are potentially effective in improving medication adherence.

OBJECTIVE

The objective of this study was to co-design, develop, and preliminarily evaluate an innovative mobile health solution called Safety and Adherence to Medication and Self-Care Advice in Oncology (SAMSON) to improve medication adherence among people with cancer.

METHODS

Using the 4 cycles and 6 processes of design science research methodology, we co-designed and developed a medication adherence solution for people with cancer. First, we conducted a literature review on medication adherence in cancer and a systematic review of current interventions to address this issue. Behavioral science research was used to conceptualize the design features of SAMSON. Second, we conducted 2 design phases: prototype design and final feature design. Last, we conducted a mixed methods study on patients with hematological cancer over 6 weeks to evaluate the mobile solution.

RESULTS

The developed mobile solution, consisting of a mobile app, a web portal, and a cloud-based database, includes 5 modules: medication reminder and acknowledgment, symptom assessment and management, reinforcement, patient profile, and reporting. The quantitative study (n=30) showed that SAMSON was easy to use (21/27, 78%). The app was engaging (18/27, 67%), informative, increased user interactions, and well organized (19/27, 70%). Most of the participants (21/27, 78%) commented that SAMSON's activities could help to improve their adherence to cancer treatments, and more than half of them (17/27, 63%) would recommend the app to their peers. The qualitative study (n=25) revealed that SAMSON was perceived as helpful in terms of reminding, supporting, and informing patients. Possible barriers to using SAMSON include the app glitches and users' technical inexperience. Further needs to refine the solution were also identified. Technical improvements and design enhancements will be incorporated into the subsequent iteration.

CONCLUSIONS

This study demonstrates the successful application of behavioral science research and design science research methodology to design and develop a mobile solution for patients with cancer to be more adherent. The study also highlights the importance of applying rigorous methodologies in developing effective and patient-centered digital intervention solutions.

Effect of hospital-community online management on medication management of elderly patients with peritoneal dialysis during COVID-19

INTRODUCTION

The study aimed to explore feasibility and effect of hospital-community online management on the medication management of elderly peritoneal dialysis (PD) patients with end-stage renal disease (ESRD) during COVID-19.

METHODS

A total of 160 patients receiving PD were randomly divided into the control (n = 80, outpatient follow-up management mode) and observation (n = 80, hospital-community online management mode) groups. The self-efficacy (General Self-Efficacy Scale [GSES]), medication adherence (8-item Morisky medication adherence scale [MMAS-8]), quality of life (kidney disease quality of life short form [KDQOL-SF]), and degree of depression (beck depression inventory [BDI]) before and after the intervention were compared.

RESULTS

After the intervention, the scores of GSES (4.20 ± 0.46 vs. 3.09 ± 0.33), MMAS-8 (5.82 ± 0.92 vs. 5.13 ± 1.25), and KDQOL-SF were significantly higher, whereas the BDI score (9.50 ± 2.86 vs. 12.08 ± 2.95) was significantly lower in the observation group than in the control group (p < 0.05).

CONCLUSION

Hospital-community online management presents good effects in the medication management of PD patients with ESRD.

Adherence to antihypertensives in the United States: A comparative meta-analysis of 23 million patients

Adherence to antihypertensives is crucial for control of blood pressure. This study analyzed factors and interventions that could affect adherence to antihypertensives in the US. PubMed, Scopus, Web of Science, and Embase were searched on January 21, 2022 and December 25, 2023 for studies on the adherence to antihypertensives in the US. Nineteen studies and 23 545 747 patients were included in the analysis, which showed that adherence to antihypertensives was the highest among Whites (OR: 1.47, 95% CI 1.34-1.61 compared to African Americans). Employment status and sex were associated with insignificant differences in adherence rates. In contrast, marital status yielded a significant difference where unmarried patients demonstrated low adherence rates compared to married ones (OR: 0.8, 95% CI 0.67-0.95). On analysis of comorbidities, diabetic patients reported lower adherence to antihypertensives (OR: 0.95, 95% CI 0.92-0.97); furthermore, patients who did not have Alzheimer showed higher adherence rates. Different BMIs did not significantly affect the adherence rates. Patients without insurance reported significantly lower adherence rates than insured patients (OR: 3.93, 95% CI 3.43-4.51). Polypill users had higher adherence rates compared with the free-dose combination (OR: 1.21, 95% CI 1.2-1.21), while telepharmacy did not prove to be as effective. Lower adherence rates were seen among African Americans, uninsured, or younger patients. Accordingly, interventions such as fixed-dose combinations should be targeted at susceptible groups. Obesity and overweight did not affect the adherence to antihypertensives.

The Impact of Prescription Drug Coverage on Disparities in Adherence and Medication Use: A Systematic Review

Prescription drug cost-sharing is a barrier to medication adherence, particularly for low-income and minority populations. In this systematic review, we examined the impact of prescription drug cost-sharing and policies to reduce cost-sharing on racial/ethnic and income disparities in medication utilization. We screened 2,145 titles and abstracts and identified 19 peer-reviewed papers that examined the interaction between cost-sharing and racial/ethnic and income disparities in medication adherence or utilization. We found weak but inconsistent evidence that lower cost-sharing is associated with reduced disparities in adherence and utilization, but studies consistently found that significant disparities remained even after adjusting for differences in cost-sharing across individuals. Study designs varied in their ability to measure the causal effect of policy or cost-sharing changes on disparities, and a wide range of policies were examined across studies. Further research is needed to identify the types of policies that are best suited to reduce disparities in medication adherence.

Translation of a Successful Behavioral Intervention to a Digital Therapeutic Self-Management System for Older Adults

Feature at a Glance: Nonadherence to hypertension medications is associated with negative health outcomes, which is of particular importance for older adults because of the high prevalence of hypertension in this population. To promote medication adherence among this group, we translated a behavioral intervention that improved adherence by 36% into a digital therapeutic self-management system. Design strategies included interviewing older adults, conducting usability evaluations after each iteration, and engaging a team of experts from nursing, cognitive psychology, pharmacy, human factors in aging, and software development. We outline our design process that can guide translation of other behavioral interventions into digital therapeutic platforms.

Thematic Analysis of Alzheimer's Medication Management Discussion in a Non-Moderated Online Forum

BACKGROUND

Managing medications for Alzheimer's disease and related dementias is challenging for caregivers. Information about caregivers' strategies to manage these challenges is needed to inform intervention development.

OBJECTIVE

This study aimed to understand caregivers' medication management experiences by analyzing online community discussions.

METHODS

Posts were extracted from the ALZConnected® Forum using keywords "medication" and "drug" via web scraping. The researchers applied thematic analysis.

RESULTS

Four major themes emerged: (1) role transition of medication management responsibilities, (2) caregivers' uncertainty about medication purpose and values, (3) conflicts between the care recipients and caregivers, and (4) difficulty accessing and affording medications.

CONCLUSIONS

The experiences shared on a non-moderated, unstructured online forum indicate that medication management is challenging and overwhelming for caregivers of people living with Alzheimer's disease and related dementias. Since this is a progressive disease with various stages and changing needs, caregivers' strategies vary and are often limited by available resources and support. Health care providers should offer training and support for caregivers to navigate the transfer of medication management responsibilities and changing care needs as the disease progresses.

Mobile phone text messaging for medication adherence in secondary prevention of cardiovascular disease

BACKGROUND

Cardiovascular diseases (CVDs) are the leading cause of death globally, accounting for almost 18 million deaths annually. People with CVDs have a five times greater chance of suffering a recurrent cardiovascular event than people without known CVDs. Although drug interventions have been shown to be cost-effective in reducing the risk of recurrent cardiovascular events, adherence to medication remains suboptimal. As a scalable and cost-effective approach, mobile phone text messaging presents an opportunity to convey health information, deliver electronic reminders, and encourage behaviour change. However, it is uncertain whether text messaging can improve medication adherence and clinical outcomes. This is an update of a Cochrane review published in 2017.

OBJECTIVES

To evaluate the benefits and harms of mobile phone text messaging for improving medication adherence in people with CVDs compared to usual care.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, four other databases, and two trial registers. We also checked the reference lists of all primary included studies and relevant systematic reviews and meta-analyses. The date of the latest search was 30 August 2023.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) with participants with established arterial occlusive events. We included trials investigating interventions using short message service (SMS) or multimedia messaging service (MMS) with the aim of improving adherence to medication for the secondary prevention of cardiovascular events. The comparator was usual care. We excluded cluster-RCTs and quasi-RCTs.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were medication adherence, fatal cardiovascular events, non-fatal cardiovascular events, and combined CVD event. Secondary outcomes were low-density lipoprotein cholesterol for the effect of statins, blood pressure for antihypertensive drugs, heart rate for the effect of beta-blockers, urinary 11-dehydrothromboxane B2 for the antiplatelet effects of aspirin, adverse effects, and patient-reported experience. We used GRADE to assess the certainty of the evidence for each outcome.

MAIN RESULTS

We included 18 RCTs involving a total of 8136 participants with CVDs. We identified 11 new studies in the review update and seven studies in the previous version of the review. Participants had various CVDs including acute coronary syndrome, coronary heart disease, stroke, myocardial infarction, and angina. All studies were conducted in middle- and high-income countries, with no studies conducted in low-income countries. The mean age of participants was 53 to 64 years. Participants were recruited from hospitals or cardiac rehabilitation facilities. Follow-up ranged from one to 12 months. There was variation in the characteristics of text messages amongst studies (e.g. delivery method, frequency, theoretical grounding, content used, personalisation, and directionality). The content of text messages varied across studies, but generally included medication reminders and healthy lifestyle information such as diet, physical activity, and weight loss. Text messages offered advice, motivation, social support, and health education to promote behaviour changes and regular medication-taking. We assessed risk of bias for all studies as high, as all studies had at least one domain at unclear or high risk of bias. Medication adherence Due to different evaluation score systems and inconsistent definitions applied for the measurement of medication adherence, we did not conduct meta-analysis for medication adherence. Ten out of 18 studies showed a beneficial effect of mobile phone text messaging for medication adherence compared to usual care, whereas the other eight studies showed either a reduction or no difference in medication adherence with text messaging compared to usual care. Overall, the evidence is very uncertain about the effects of mobile phone text messaging for medication adherence when compared to usual care. Fatal cardiovascular events Text messaging may have little to no effect on fatal cardiovascular events compared to usual care (odds ratio 0.83, 95% confidence interval (CI) 0.47 to 1.45; 4 studies, 1654 participants; low-certainty evidence). Non-fatal cardiovascular events We found very low-certainty evidence that text messaging may have little to no effect on non-fatal cardiovascular events. Two studies reported non-fatal cardiovascular events, neither of which found evidence of a difference between groups. Combined CVD events We found very low-certainty evidence that text messaging may have little to no effect on combined CVD events. Only one study reported combined CVD events, and did not find evidence of a difference between groups. Low-density lipoprotein cholesterol Text messaging may have little to no effect on low-density lipoprotein cholesterol compared to usual care (mean difference (MD) -1.79 mg/dL, 95% CI -4.71 to 1.12; 8 studies, 4983 participants; very low-certainty evidence). Blood pressure Text messaging may have little to no effect on systolic blood pressure (MD -0.93 mmHg, 95% CI -3.55 to 1.69; 8 studies, 5173 participants; very low-certainty evidence) and diastolic blood pressure (MD -1.00 mmHg, 95% CI -2.49 to 0.50; 5 studies, 3137 participants; very low-certainty evidence) when compared to usual care. Heart rate Text messaging may have little to no effect on heart rate compared to usual care (MD -0.46 beats per minute, 95% CI -1.74 to 0.82; 4 studies, 2946 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

Due to limited evidence, we are uncertain if text messaging reduces medication adherence, fatal and non-fatal cardiovascular events, and combined cardiovascular events in people with cardiovascular diseases when compared to usual care. Furthermore, text messaging may result in little or no effect on low-density lipoprotein cholesterol, blood pressure, and heart rate compared to usual care. The included studies were of low methodological quality, and no studies assessed the effects of text messaging in low-income countries or beyond the 12-month follow-up. Long-term and high-quality randomised trials are needed, particularly in low-income countries.

Usability testing of a mobile health application to support individuals with active tuberculosis: a mixed methods study

Poor adherence to tuberculosis (TB) treatment leads to further disease transmission, worsened outcomes, and the development of drug resistance. Digital adherence technologies may facilitate a more patient-centered approach for improving TB treatment outcomes than current strategies. The objective of this study was to evaluate and explore improving usability of the TB Treatment Support Tools (TB-TST) mobile application. We used an iterative convergent mixed-method design consisting of two quantitative surveys and a qualitative think-aloud interview. Testing was conducted in three testing cycles consisting of a total of 16 interviews and 26 surveys. Results were thematically analyzed and reported to the development team during weekly team meetings. Participants rated the TB-TSTs application as having high usability and the iterative approach resulted in several refinements to the application in response to participant feedback. These refinements were well received during qualitative interviews but did not result in a statistically significant improvement in usability testing scores between cycles. Using an iterative convergent mixed-method design was an effective method for refining our mHealth application. Data collected from think-aloud interviews, the MAUQ, and the Health-ITUES identified key areas of application design that needed refinement.

Barriers to Medication Adherence Among Patients with Non-Communicable Disease in North Wollo Zone Public Hospitals: Socio-Ecologic Perspective, 2023

Background

The practice of taking medication as directed by a healthcare provider is known as medication adherence. Therefore, the application of a socio-ecological model to this study identifies multilevel factors on barriers of medication adherence on chronic non-communicable disease and provides information to develop scientific health communication interventional strategies to improve medication adherence.

Objective

This study aimed to explore barriers of medication adherence on non-communicable disease prevention and care among patients in North Wollo Zone public hospitals, northeast Ethiopia.

Methods

A phenomenological study design was carried out between February 5 and February 30, 2023. The study participants were chosen using a heterogeneous purposive sampling technique. In-depth interviews and targeted focus groups were used to gather data. The focus group discussions and in-depth interviews were captured on audio, accurately transcribed, and translated into English. Atlas TI-7 was utilized to do the thematic analysis.

Results

Four main themes, intrapersonal, interpersonal, community level, and health care related, as well as seven subthemes, financial problems, lack of family support, poor communication with healthcare providers, effects of social ceremonies, remote healthcare facility, and drug scarcity, were identified by this study. In this study participants reported that lack of knowledge about the disease and drugs were the main barrier for medication adherence. The study revealed that financial problems for medication and transportation cost were the main factor for medication adherence for non-communicable disease patients.

Conclusion

This study explored that lack of knowledge, financial problem, lack of family support, poor communication with healthcare providers, social ceremony effects, remote healthcare facility, and scarcity of drugs were barriers of medication adherence among non-communicable disease patients. In order to reduce morbidity and mortality from non-communicable diseases, it is advised that all relevant bodies look for ways to reduce medication adherence barriers for patients at every level of influence.

A content analysis of medication adherence material in patient educational resources about gout

Objective

This study aimed to investigate how medication adherence is addressed in online gout resources in six countries. We investigated how often adherence was referred to, the strategies suggested to improve patient adherence, and the types of nonadherence that were targeted. We also examined the readability of the adherence material.

Methods

A content analysis was conducted on 151 online gout resources from medical and health organisations in six predominantly English-speaking countries. Two reviewers coded the content of the websites into categories (kappa 0.80). The analysis involved coding the resources for reasons for nonadherence, and adherence-promoting strategies. Flesch-Kincaid Reading Ease scores and word count were also computed.

Results

Out of 151 websites examined, 77 websites discussed medication adherence (51%), with intentional nonadherence being more prevalent than unintentional nonadherence. 67 websites targeted different types of nonadherence, including drug-specific concerns (50%), misconceptions of gout curability and the necessity of medication (16%), forgetfulness (16%), and other practical challenges (5%). Strategies to promote adherence were found in one-third of the websites, with medication education being the most prevalent strategy (17%), followed by healthcare provider engagement (13%) and memory aid strategies (6%). On average, about 11% of the words (89.27, SD = 76.35) in the entire document were focused on adherence. Difficult reading comprehension was found in one-fifth of adherence-related websites.

Conclusion

Findings reveal limited medication adherence coverage and narrow strategies in online gout resources. Improved adherence portrayal is needed for effective gout management through comprehensive strategies and clear, understandable information.

Quality Assessment of Smartphone Medication Management Apps in France: Systematic Search

BACKGROUND

Adherence to medication is estimated to be around 50% for chronically ill patients in high-income countries. Improving the effectiveness of adherence interventions could have a far greater impact on population health than any improvement in specific medical treatments. Mobile health (mHealth) is one of the most effective solutions for helping patients improve their medication intake, notably through the use of mobile apps with reminder systems. With more than 327,000 apps available in the mHealth field, it is difficult for health care professionals and patients alike to choose which apps to recommend and use.

OBJECTIVE

We aim to carry out a systematic search of medication management smartphone apps available in France that send reminders to patients and assess their quality using a validated scale.

METHODS

Mobile apps were identified in October and November 2022 after a systematic keyword search on the 2 main app download platforms: App Store (Apple Inc) and Google Play Store. Inclusion criteria were free availability, date of last update, and availability in French. Next, 2 health care professionals independently evaluated the included apps using the French version of the Mobile App Rating Scale (MARS-F), an objective scoring system validated for assessing the overall quality of apps in the mHealth field. An intraclass correlation coefficient was calculated to determine interrater reliability.

RESULTS

In total, 960 apps were identified and 49 were selected (25 from the App Store and 24 from the Google Play Store). Interrater reliability was excellent (intraclass correlation coefficient 0.92; 95% CI 0.87-0.95; P<.001). The average MARS-F score was 3.56 (SD 0.49) for apps on the App Store and 3.51 (SD 0.46) for those on the Google Play Store, with 10 apps scoring above 4 out of 5. Further, 2 apps were tested in at least one randomized controlled trial and showed positive results. The 2 apps with the highest ratings were Mediteo rappel de médicaments (Mediteo GmbH) and TOM rappel medicaments, pilule (Innovation6 GmbH), available on both platforms. Each app's MARS-F score was weakly correlated with user ratings on the App Store and moderately correlated on the Google Play Store.

CONCLUSIONS

To our knowledge, this is the first study that used a validated scoring system to evaluate medication management apps that send medication reminders. The quality of the apps was heterogeneous, with only 2 having been studied in a randomized controlled trial with positive results. The evaluation of apps in real-life conditions by patients is necessary to determine their acceptability and effectiveness. Certification of apps is also essential to help health care professionals and patients identify validated apps.

Evaluation of adherence to antipsychotics: A real-world data study using four different dosing assumptions

AIMS

This study aimed to assess the frequency of dosing inconsistencies in prescription data and the effect of four dosing assumption strategies on adherence estimates for antipsychotic treatment.

METHODS

A retrospective cohort, which linked prescription and dispensing data of adult patients with ≥1 antipsychotic prescription between 2015-2016 and followed up until 2019, in Catalonia (Spain). Four strategies were proposed for selecting the recommended dosing in overlapping prescription periods for the same patient and antipsychotic drug: (i) the minimum dosing prescribed; (ii) the dose corresponding to the latest prescription issued; (iii) the highest dosing prescribed; and (iv) all doses included in the overlapped period. For each strategy, one treatment episode per patient was selected, and the Continuous Medication Availability measure was used to assess adherence. Descriptive statistics were used to describe results by strategy.

RESULTS

Of the 277 324 prescriptions included, 76% overlapped with other prescriptions (40% with different recommended dosing instructions). The number and characteristics of patients and treatment episodes (18 292, 18 303, 18 339 and 18 536, respectively per strategy) were similar across strategies. Mean adherence was similar between strategies, ranging from 57 to 60%. However, the proportion of patients with adherence ≥90% was lower when selecting all doses (28%) compared with the other strategies (35%).

CONCLUSION

Despite the high prevalence of overlapping prescriptions, the strategies proposed did not show a major effect on the adherence estimates for antipsychotic treatment. Taking into consideration the particularities of antipsychotic prescription practices, selecting the highest dose in the overlapped period seemed to provide a more accurate adherence estimate.

Immunosuppressant medication behaviours in solid organ transplant recipients: a cross-sectional study from south-central China during COVID-19 reopening period

OBJECTIVE

Medication non-adherence to immunosuppressants threatens allograft survival and function maintenance among solid organ transplant (SOT) recipients. This study aimed to investigate the prevalence of immunosuppressant medication non-adherence and associated factors during the COVID-19 reopening period among Chinese SOT recipients.

DESIGN

Cross-sectional study.

SETTING

South-central China.

POPULATION

Adult patients who received SOT with functioning graft.

METHODS

Sociodemographic questionnaire and scales to measure physical activity, depression and medication non-adherence were used to collect data. Logistic regression analysis was conducted to identify factors associated with medication non-adherence. Mediation and moderated mediation analyses were performed to examine the potential mechanisms influencing medication behaviour during the pandemic reopening period using SPSS PROCESS macro 4.3 software.

RESULTS

A total of 1121 participants were recruited and the prevalence of medication non-adherence was 36.3% in this study. Recipients who were men, had a higher monthly income, lived alone, had received transplantation for a minimum of 3 years, had received COVID-19 vaccination and experienced depressive symptoms exhibited an increased risk of non-adherence. Contrarily, those who engaged in high-intensity physical activity exhibited a decreased risk. Physical activity was negatively associated with medication non-adherence (r=-0.124, p<0.001) with depression fully mediating this relationship (B=-0.014, 95% CI: -0.032 to -0.003). COVID-19 vaccination significantly moderated the relationship between physical activity and depression (B=-0.303, 95% CI: -0.515 to -0.090).

CONCLUSION

This study investigated the prevalence of medication non-adherence among SOT recipients during the COVID-19 reopening period in China, its associated factors and a potential mechanism. Depression fully mediated the association between physical activity and medication non-adherence, and COVID-19 vaccination moderated the relationship between physical activity and depression. These findings provide some insights for managing medication behaviour when confronting public health emergencies. However, relationships displayed in the moderated mediation model should be tracked after returning to normal life and other potential relationships should be explored to deeply understand medication non-adherent behaviour.

The Digital Therapeutics Real-World Evidence Framework: An Approach for Guiding Evidence-Based Digital Therapeutics Design, Development, Testing, and Monitoring

Digital therapeutics (DTx) are a promising way to provide safe, effective, accessible, sustainable, scalable, and equitable approaches to advance individual and population health. However, developing and deploying DTx is inherently complex in that DTx includes multiple interacting components, such as tools to support activities like medication adherence, health behavior goal-setting or self-monitoring, and algorithms that adapt the provision of these according to individual needs that may change over time. While myriad frameworks exist for different phases of DTx development, no single framework exists to guide evidence production for DTx across its full life cycle, from initial DTx development to long-term use. To fill this gap, we propose the DTx real-world evidence (RWE) framework as a pragmatic, iterative, milestone-driven approach for developing DTx. The DTx RWE framework is derived from the 4-phase development model used for behavioral interventions, but it includes key adaptations that are specific to the unique characteristics of DTx. To ensure the highest level of fidelity to the needs of users, the framework also incorporates real-world data (RWD) across the entire life cycle of DTx development and use. The DTx RWE framework is intended for any group interested in developing and deploying DTx in real-world contexts, including those in industry, health care, public health, and academia. Moreover, entities that fund research that supports the development of DTx and agencies that regulate DTx might find the DTx RWE framework useful as they endeavor to improve how DTxcan advance individual and population health.

Enhancing Patient Adherence to Newly-Prescribed Medicine for Chronic Diseases: A Comprehensive Review and Cost-Effective Approach to Implementing the New Medicine Service in Community Pharmacies in Poland

New Medicine Service (NMS) components are an important element to improve patient compliance with medical recommendations. NMS provides support to patients prescribed new medicines, helping them to manage long-term conditions. The purpose of this service is to provide patients with advice, guidelines, and educational materials regarding the use of new medicines to increase patient compliance and therapy safety. The NMS has already been introduced in many European countries. This review aims to identify the benefits and potential barriers to implementing the NMS in community pharmacies and to suggest solutions that would increase its effectiveness. Previous studies have primarily shown that the NMS improves patient compliance with therapy, accelerating the expected effects of the therapy. Pharmacist support during implementation of a new drug therapy substantially increases patient safety. As the experience of numerous countries shows, both pharmacists and patients express positive opinions on this service. Therefore, it seems that NMS should be an indispensable part of pharmaceutical patient care in any healthcare system. This article aims to review the implementation of the New Medicine Service (NMS) for community pharmacists in Poland and the provision of a cost-effective approach to improve patient adherence to newly-prescribed medicine for chronic diseases.

Predictors of Patient-reported and Pharmacy Refill Measures of Maintenance Inhaler Adherence in Veterans with Chronic Obstructive Pulmonary Disease

Rationale: Suboptimal adherence to inhaled medications in patients with chronic obstructive pulmonary disease (COPD) remains a challenge. Objectives: To examine the sociodemographic and clinical characteristics and medication beliefs associated with adherence measured by self-report and pharmacy data. Methods: A cross-sectional analysis of data from a prospective observational cohort study of patients with COPD was completed. Participants underwent spirometry and completed questionnaires regarding sociodemographic data, inhaler use, dyspnea, social support, psychological and medical comorbidities, and medication beliefs (Beliefs about Medicines Questionnaire [BMQ]). Self-reported adherence to inhaled medications was measured with the Adherence to Refills and Medications Scale (ARMS), and pharmacy-based adherence was calculated from administrative data using the ReComp score. Multivariable linear regression was used to examine the sociodemographic, clinical, and medication-belief factors associated with both adherence measures. Results: Among 269 participants with ARMS and ReComp data, adherence was the same for each measure (38.3%), but only 18% of participants were adherent by both measures. In multivariable adjusted analysis, a 10-year increase in age (β = 0.54; 95% confidence interval, 0.14-0.94) and the number of maintenance inhalers used (β = 0.53; 0.04-1.02) were associated with increased adherence by self-report. Improved ReComp adherence was associated with chronic prednisone use (β = 0.18; 0.04-0.31) and the number of maintenance inhalers used (β = 0.11; 0.05-0.17). In adjusted analyses examining patient beliefs about medications, increases in the COPD-specific BMQ concerns score (β = -0.10; -0.17 to -0.02) were associated with reduced self-reported adherence. No significant associations between ReComp adherence and BMQ score were found in adjusted analyses. Conclusions: Adherence to inhaled COPD medications was poor as measured by self-report or pharmacy refill data. There were notable differences in factors associated with adherence based on the method of adherence measurement. Older age, chronic prednisone use, the number of prescribed maintenance inhalers used, and patient beliefs about medication safety were associated with adherence. Overall, fewer variables were associated with adherence as measured based on pharmacy refills. Pharmacy refill-based and self-reported adherence may measure distinct aspects of adherence and may be affected by different factors. These results also underscore the importance of addressing patient beliefs when developing interventions to improve medication adherence.

The IMPACT (Infection Management Plus Addiction Care Together) Pilot: A Case Series of Combined Contingency Management for Substance Use Disorders and Antibiotic Adherence in the Hospital Setting

OBJECTIVES

Psychostimulant-related mortality is rising alongside increasing substance use-related hospitalizations, which are commonly complicated by patient-directed (or "against medical advice") discharges. Contingency management (CM) is an underused evidence-based treatment for substance use disorders with proven efficacy to support medication adherence. Our objective was to describe feasibility and preliminary effectiveness of a novel CM intervention incentivizing both drug use reduction and antibiotic adherence in the hospital setting.

METHODS

We conducted a pilot intervention of twice weekly CM for stimulant and/or opioid use disorder and antibiotic adherence conducted on inpatient wards and/or an embedded skilled nursing facility in an urban public hospital. Based on point-of-care urine drug test results and objective antibiotic adherence review, participants earned increasing opportunities to receive incentives. We measured feasibility via number of visits attempted and cost of gift cards dispensed. We evaluated effectiveness via antibiotic completion, discharge type, and participant perception of intervention effectiveness collected via structured survey.

RESULTS

Of 13 participants enrolled, most had opioid use disorder (fentanyl in 10/13) and stimulant use disorder (methamphetamine in 7/13). Almost all were receiving treatment for osteomyelitis and/or endocarditis (12/13). Feasibility challenges included competing demands of acute care with variable range of completed visits per participant (1-12 visits). Despite this, antibiotic completion was high (92%, 12/13 participants) with only two patient-directed discharges. Participants described CM as very effective in aiding infection treatment but had greater variability in beliefs regarding CM facilitation of reduced drug use.

CONCLUSIONS

Providing CM in the hospital setting may represent an effective approach to improving health outcomes by increasing antibiotic adherence and addressing substance use.

Quality of life and adherence to antiretroviral therapy in people living with HIV in the Ceará, Brazil

The aim of this study was to investigate the quality of life (QOL) and adherence to antiretroviral therapy (ART) in people living with HIV (PLWH) in Fortaleza, Ceará, Brazil. A cross-sectional study with a sample of 385 patients followed-up on an outpatient basis. Interviews were conducted using the Sociodemographic, Epidemiological and Clinical Form, the World Health Organization's Quality of Life in PLWH Instrument, the Assessment of Adherence to Antiretroviral Treatment Questionnaire and Pittsburgh Sleep Quality Index. Descriptive statistics and univariate and multivariate logistic regression analysis were performed. The odds ratio and confidence interval were calculated, considering P < 0.05 as statistically significant. Of the 385 PLWH, 134 (34.8%) had unsatisfactory QOL which was associated with unemployment (P = 0.0037), monthly income less than the minimum wage (P < 0.0001), sleep disorders (P = 0.0039) and not doing regular exercise (P = 0.0032). Inadequate adherence to ART occurred in 24 patients (6.23%) and was associated with detectable viral load (P = 0.0001) and unsatisfactory QOL (P = 0.0033). QOL was more unsatisfactory for those unemployed and with low income, sleep disorders and sedentary lifestyle. People with detectable viral load and unsatisfactory QOL had more inadequate adherence to ART.

Prevalence, medication adherence, and determinants of type 2 diabetes mellitus during Coronavirus Disease 2019 pandemic among adults in Tanzania

Introduction

Excessive consumption of comfort foods, which are mostly high in carbs, and limitations on outdoor and gym-based physical activities, for instance, are associated with foods high in the glycemic index and raise the risk of obesity and type 2 diabetes. In pandemic and or epidemic situations, peoples' lifestyles may change significantly to lead them to non-communicable diseases. However, lifestyle changes and the occurrence of type 2 diabetes mellitus during the Coronavirus Disease 2019 pandemic among adults have not been well established in Tanzania. This study assessed the prevalence, medication adherence, and determinants of type 2 diabetes mellitus among adults in the country.

Methods

A community-based analytical cross-sectional study was conducted in Dodoma region, Tanzania between September and October 2020 of which 107 adults aged above 18 years were studied regardless of whether they were newly diagnosed with type 2 diabetes mellitus or not using a quantitative research approach. Interviewer-administered lifestyle habits and medication adherence structured questionnaires benchmarked from previous studies served as the main tools of data collection. The statistical package for social sciences computer program was used to analyze the data descriptively for frequencies and percentages and by regression analysis model to determine the association between variables with a 95% confidence interval and 5% significance level.

Results

With a mean age of 31 ± 2.527 years, 59.8% of the respondents were female. 60.7% and 11.7% of the respondents had unhealthy and moderate lifestyle choices respectively. The prevalence of type 2 diabetes mellitus accounted for 63.9% of the respondents of which 44.6% were diagnostically confirmed during the Coronavirus Disease 2019 pandemic against 19.3% of respondents who were diagnosed before the pandemic. Medication adherence among the type 2 diabetes mellitus respondents accounted for 77.9% of the study respondents. Type 2 diabetes mellitus was significantly associated with being in the 36-55 age group (AOR = 1.054; 95% CI: 0.292, 3.162; p < 0.05); being female (AOR = 1.398; 95% CI: 0.205, 3.048; p < 0.05); having a job (AOR = 2.597; 95% CI: 1.243, 4.402, p < 0.05); and having unhealthy lifestyle habits (AOR = 3.301; 95% CI: 1.199, 6.52; p < 0.05).

Conclusion

The majority of adults had type 2 diabetes mellitus of which most of them were confirmed to have the disease during the Coronavirus Disease 2019 pandemic. Few type 2 diabetes mellitus adults did not adhere to their medications as recommended. Their sociodemographic characteristics profiles and unhealthy lifestyles significantly led them to have the problem. The treatment of the disease above and health promotion activities may need to take unhealthy lifestyle choices and certain sociodemographic profiles of adults into consideration to assist in preventing the problem.

Factors Associated With Antiretroviral Adherence Among Youth Living With HIV

BACKGROUND

Youth living with HIV (YLH) have an increased risk for psychosocial stressors that can affect their antiretroviral (ARV) adherence. We examined factors associated with self-reported ARV adherence among YLH ages 12-24 years old.

SETTING

YLH (N = 147) were recruited in Los Angeles, CA, and New Orleans, LA from 2017 to 2020.

METHODS

YLH whose self-reported recent (30 days) ARV adherence was "excellent" or "very good" were compared with nonadherent YLH on sociodemographic, clinical, and psychosocial factors using univariate and multivariate analyses.

RESULTS

Participants were predominantly male (88%), and 81% identified as gay, bisexual, transgender, queer, or other. The mean duration on ARV was 27 months (range 0-237 months). Most YLH (71.2%) self-reported being adherent, and 79% of those who self-reported adherence were also virally suppressed (<200 copies/mL). Multivariate analysis indicated being adherent was significantly associated with white race [aOR = 8.07, confidence intervals (CI): 1.45 to 74.0], Hispanic/Latinx ethnicity [aOR = 3.57, CI: 1.16 to 12.80], more social support [aOR = 1.11, CI: 1.05 to 1.18], and being on ARV for a shorter duration [aOR = 0.99, CI: 0.97 to 0.99]. Mental health symptoms, substance use, age, and history of homelessness or incarceration were unrelated to adherence.

CONCLUSIONS

Enhancing efforts to provide support for adherence to non-white youth, and those with limited social support and who have been on ARV treatment longer, may help increase viral suppression among YLH.

A Cross-Sectional Study of Cognitive Function, Illness Perceptions, and Immunosuppression Medication Adherence After Heart Transplantation

BACKGROUND

There are few studies that examine relationships between cognitive function, illness perceptions, and medication adherence after heart transplantation, limiting the development of effective adherence-promoting interventions.

OBJECTIVE

The purpose of this study was to describe relationships between cognitive function, illness perceptions, and medication adherence among heart transplant recipients.

METHODS

A cross-sectional, observational design was used. Measures included the telephone-Montreal Cognitive Assessment (t-MoCA©), Patient Health Questionnaire-9, Brief Test of Adult Cognition by Telephone, Basel Assessment of Adherence to Immunosuppressive Medications Scale, and the Brief Illness Perceptions Questionnaire. Descriptive statistics, point-biserial correlations, Pearson's correlations, and logistic regression were used to describe relationships.

RESULTS

Of the 35 participants (mean age: 61 years [SD: 10.3], 71.4% male, 71.4% white), 31.4% (n = 11) were classified as nonadherent to their immunosuppression medications. Higher immediate word recall, indicating better episodic memory (memory for autobiographical and recent events), and higher illness coherence scores were associated with not missing doses of medication. Higher t-MoCA© total scores, indicating normal cognitive function, and lower depression scores were associated with taking medications on time. More than 22% (n = 8) of participants scored less than 19 on the t-MoCA©, an indication of mild cognitive impairment.

CONCLUSION

Cognitive impairment may be more common among heart transplant recipients than what is currently recognized, and specific domains of cognitive function were related to medication adherence after transplantation in this study. Future studies should include longitudinal evaluations of cognitive function, depression, and medication adherence. Consideration of these relationships is needed when designing adherence-promoting interventions for this population.

A machine-learning assisted review of the use of habit formation in medication adherence interventions for long-term conditions

Adherence to medication in long-term conditions is around 50%. The key components of successful interventions to improve medication adherence remain unclear, particularly when examined over prolonged follow-up periods. Behaviour change theories are increasingly interested in the utility of habit formation for the maintenance of health behaviour change, but there is no documentation on how habit has been conceptualised in the medication adherence intervention literature, or what effect the key technique identified in habit formation theory (context dependent repetition) has in these studies. To examine this, a machine-learning assisted review was conducted. Searches of MEDLINE, EMBASE and PSYCInfo and the reference list of a comprehensive systematic review of medication adherence interventions yielded 5973 articles. Machine learning-assisted title and abstract screening identified 15 independent RCTs published between 1976 and 2021, including 18 intervention comparisons of interest. Key findings indicate that conceptualisations of habit in the medication adherence literature are varied and behaviour change technique coding identified only six studies which explicitly described using habit formation. Future work should aim to develop this evidence base, drawing on contemporary habit theory and with explicit demonstration of what techniques have been used to promote habit formation.

A systematic review of interventions to improve medication adherence in adults with mental-physical multimorbidity in primary care

BACKGROUND

Medication non-adherence is a significant contributor to healthcare inefficiency, resulting in poor medication management, impaired patient outcomes and ineffective symptom control. This review summarises interventions targeting medication adherence for adults with mental-physical multimorbidity, in primary healthcare settings.

METHODS

A systematic review of literature was conducted using Medline, Embase, PsycInfo, Web of Science, Cochrane Library, and CINAHL were searched for relevant studies. Data were extracted and synthesized using narrative synthesis. The Cochrane Effective Practice and Organisation of Care (EPOC) was used to classify intervention types. Risk of bias was assessed using the National Heart, Lung, and Blood Institute (NHLBI) quality assessment tool.

RESULTS

Eleven studies representing 2,279 patients were included. All interventions examined were classified into one EPOC domain, which was delivery arrangements. All included studies examined patients with a physical condition, alongside depression. Seven studies examining coordination of care and management of care processes interventions reported significant improvements in medication adherence attributed to the intervention. Four studies considering the use of information and communication technology observed no changes in medication adherence.

CONCLUSION

Interventions that coordinate and manage healthcare processes may help improve how patients adhere to their medication regimes, particularly in patients with mental-physical multimorbidity. However, we still need to better understand how digital health technology can support patients in following their medication regimes. As we face the growing challenges of treating multimorbidity, everyone involved in health services - from providers to policymakers - must be receptive to a more integrated approach to the delivery of healthcare.

Participant Perspectives on the Implementation of a School-Linked Text-Message Intervention to Improve Pediatric Asthma Medication Adherence

Background: Poor adherence to inhaled corticosteroids (ICS) is a significant challenge in pediatric asthma, contributing to health inequities. Text-message reminders for ICS therapy are an evidence-based approach that improves pediatric asthma medication adherence, yet has not been widely adopted into practice, partly due to lack of (1) participant input on design and implementation and (2) use of sustainable community linkages. Remote Asthma Link™ (RAL) seeks to fill this gap as a school-linked text-message intervention wherein parents of children with poorly controlled asthma received daily, 2-way text-message reminders for preventive inhaler use. Responses were shared with school nurses who conducted remote check-ins with families. Enrolled children, largely from underserved backgrounds, experienced improvements in medication adherence and asthma health outcomes. While initial results were promising, we have yet to elicit participant input to refine the protocol for more widespread implementation. Objective: Examine participant perspectives on barriers and facilitators of RAL implementation. Methods: Semistructured interviews were conducted May-June 2022 with intervention participants: 10 parents, 7 school nurses, and 4 pediatric providers (n = 21) until thematic saturation was reached. Interview transcripts were coded using thematic analysis. Results: Several facilitators for RAL implementation were identified, including ease of use and accessibility, personal connection to the school nurse, and receipt of a visual notification for habit formation. Barriers included challenges with school nurses reaching parents, poor understanding of program expectations, and lack of reimbursement structure. Participant-proposed solutions to barriers included utilizing alternate communication methods (eg, social media), educational sessions, and meeting with payors to consider reimbursement models. Conclusion: RAL is a school-linked text-message intervention demonstrating promise in improving outcomes and equity in asthma care. Key implementation facilitators, barriers, and proposed solutions will inform protocol adaptations to promote successful implementation of this and other text-message interventions into clinical practice.

Prescription patterns of ambrisentan in some cities of Colombia

INTRODUCTION

Ambrisentan is a selective type A endothelin receptor antagonist that has shown significant effectiveness and safety in the management of patients with pulmonary hypertension. Its use pattern with real-world evidence in Colombia is unknown.

OBJECTIVE

The objective of this study is to determine the prescription patterns of ambrisentan in some cities of Colombia.

METHODS

A longitudinal descriptive study on the prescription patterns of ambrisentan in patients with pulmonary hypertension (all the groups) was conducted between January 2021 and December 2022 based on a population database of members of the Colombian Health System. Adherence at 1 year was determined using the Medication Possession Ratio (days the drug was dispensed/days from first dispensing to the end of the follow-up period × 100). Descriptive analysis was carried out.

RESULTS

Sixty-seven patients taking ambrisentan were identified in 10 cities of the country. The individuals had a median age of 51.5 years (interquartile range-IQR: 39.8-64.0 years), and 82.1% were women. The drug possession rate was 82.2% (IQR: 65.0-96.8%), and persistence at 1 year was present in 49.3% (n = 33) of the cases. The average dose was 8.8 ± 5.0 mg/day, and 76.1% (n = 51) received it in combination therapy, mainly with phosphodiesterase type 5 inhibitors (61.2%, n = 41).

CONCLUSIONS

Adherence to ambrisentan was good, but its persistence at 1 year was low. The dosages of the drug used were in accordance with the recommendations of the clinical practice guidelines, and it was used in combination therapy, especially with phosphodiesterase 5 inhibitors.

Exploring the Use of Socially Assistive Robot Among Socially Isolated Korean American Older Adults

This pilot study explored whether a socially assistive robot (SAR) would have positive effects on Korean American immigrant older adults' health behaviors and emotional well-being and whether the older adults would be receptive to the SAR. A total of 30 participants (age 65+) in a large metropolitan area participated in the study, and each participant was provided a SAR named Hyodol for 4 months and interacted with it in ways that they saw appropriate. We used one-group pre- and post-test design to assess changes between baseline and follow-up in medication adherence, depressive symptoms, loneliness, and disability. Additionally, we employed in-depth qualitative interviews to explore participants' perceptions about the SAR. At post-test, participants showed improved medication adherence, reduced depressive symptoms, and a slightly and statistically nonsignificant decrease in loneliness scores. Qualitative data suggested high adoptability of this particular SAR among the participants.

Improved Medication Adherence of an Elderly Diabetic Patient at a Dwelling Home Using a Pill Dispenser and Personal Health Records

Fookkun® is a pill dispenser in which single doses of several medications intended to be taken simultaneously are sealed in single film bags rolled onto a medication rotating drum. The system makes musical alert sounds when it is time for the patient to take the medications. If the patient misses a dose, a designated contact, such as the patient's child, is alerted. We conducted an experiment monitoring the use of a pill dispenser (Fookkun®) by an older patient. The participant was a 71-year-old woman with diabetes living in a dwelling home. The experiment lasted approximately 6 months. Fookkun® and the prototype data transmitter were installed at the patient's home. Fookkun®'s medication history data are displayed on the electronic medication record book (E-MRB) and the patient's pharmacist checks the patient's medication history on the E-MRB. The Fookkun® was effective in facilitating medication adherence. The pharmacist and the patient's daughter did not need to check the E-MRB because Fookkun® alerted them when the patient missed her medication. We believe that if the medication history data linked between a pill dispenser and an E-MRB can be shared among medical staff, this will contribute to a medical digital transformation in Japan in the future.
