Adherence to drugs that prevent cardiovascular disease: meta-analysis on 376,162 patients

How do the guideline recommendations work for you? Patients' perceived effectiveness of therapeutic approaches in arterial hypertension

Blood pressure remains in the hypertensive range in nearly half of those affected by arterial hypertension despite it being an extremely modifiable risk factor, whereby morbidity decreases significantly upon implementation of lifestyle-based therapeutic approaches. There are significant discrepancies between the S3 guideline's recommendations and its implementation. In this cross-sectional study sampling 160 inpatients with arterial hypertension, we assessed patients' perceptions of secondary prevention therapeutic approaches recommended to them within treatment guidelines. Additionally, we used psychometric questionnaires to assess prevention factors. We conducted a latent class analysis to identify patterns in patients' views, and tested for group differences regarding gender, age, education years, body mass index, psychopathology, and blood pressure. Two latent classes could be identified: Class 1 tended to perceive all recommended therapeutic approaches as helpful and reflected individuals with high-normal blood pressure. Class 2 tended to view recommendations regarding weight reduction, and cessation of nicotine and alcohol use, as less effective and included those with mild hypertension. There were no statistically significant class differences regarding the socio-demographic parameters. We further examined the evaluation of therapeutic approaches independent of classes, with social support reported to be the most effective approach. In conclusion, persistently-elevated blood pressure may be linked to poorer perceptions of therapeutic approaches which are then not implemented. Furthermore, patient-centered treatment planning and concepts such as shared decision-making appear to be central in treating this population regarding secondary prevention.

Electronic monitoring device informed interventions for treatment adherence and clinical outcomes in children and adolescents: A systematic review

OBJECTIVE

To systematically review literature from randomised controlled trials (RCTs) investigating the effectiveness of electronic monitoring device informed interventions on adherence and clinical outcomes in children and adolescents with chronic conditions.

STUDY DESIGN

A systematic review was conducted. An electronic literature search covering studies, with no pre-specified starting date up to June 2024, was performed in Medline, EMBASE, Web of Science, Cochrane and Trials databases was conducted.

PARTICIPANTS

RCTs of electronic monitoring device informed interventions in individuals aged 0 to 18 years with chronic conditions, were identified, with no restriction on geography or publication date.

METHODS

Extracted data was synthesised. As a result of differences in definitions and analysis of adherence and clinical outcomes across the studies a pooled meta-analysis was not possible therefore, a descriptive analysis was conducted. Risk of bias across all studies was assessed using the Cochrane Collaboration risk of bias tool.

RESULTS

11 RCTs, with 1485 children and adolescents were included. Studies were all from high- and middle-income countries, conducted among children and adolescents with asthma, and one each among children and adolescents with kidney transplant, multiple sclerosis, and epilepsy. Eight of the 11 studies reported a positive effect on adherence. Only four studies reported a positive effect on clinical outcomes and seven studies found no effect on clinical outcomes.

CONCLUSIONS

Electronic monitoring device interventions show promise in improving adherence in children and adolescents with chronic conditions, in a limited number of chronic conditions, mostly asthma. Evidence for the efficacy of electronic monitoring device informed interventions on clinical outcomes and from low-income settings is lacking.

Prevalence and associated factors of non-adherence to antihyperlipidemic medication: a nationwide cross sectional survey in Pakistan

Hyperlipidemia significantly contributes to the risk of developing cardiovascular diseases. However, about half of the patients do not adhere to their antihyperlipidemic medications, leading to healthcare costs and premature mortality. This study's objective was to determine the prevalence and associated factors of non-adherence to antihyperlipidemic medications. The study covered hypertensive patients (21,451) aged 21-75 years, presenting to the primary and secondary healthcare facilities across Pakistan (covering 21 divisions) from January 2022 to April 2023. The outcome intended was non-adherence to antihyperlipidemic medication, which was assessed by SEAMS and pill-counting methods (non-adherence < 80%). The study found overall non-adherence to antihyperlipidemic medication of 60.6% across Pakistan, with the highest non-adherence rates found in Azad Jammu and Kashmir (71.9%) and the lowest in Islamabad (47.7%). Multivariable logistic regression analysis revealed that female, no health card (Sehat Sahulat Program government insurance), < 5 years of illness, < 5 daily medications, and dose frequency of twice daily revealed a positively significant association with non-adherence. While monthly income 51,000-100,000, graduation level of education, Muhajir, and hyperlipidemia with one comorbid condition had a significant negative association with the non-adherence. Antihyperlipidemic non-adherence is a multifaceted, multifactorial, profound problem requiring a multipronged approach.

Effectiveness of nutritional support to improve treatment adherence in patients with tuberculosis: a systematic review

CONTEXT

Nutritional interventions substantially improve tuberculosis (TB) treatment outcomes and prevent complications. However, there is limited evidence about the connections between having nutritional support and TB treatment adherence.

OBJECTIVE

The aim of this study was to determine the effectiveness of nutritional support in improving treatment adherence among patients with TB.

DATA SOURCES

Databases, including PubMed, Embase (Ovid), Web of Science, and Scopus, were comprehensively reviewed to identify relevant studies reporting the impacts of nutritional support on TB treatment adherence.

DATA EXTRACTION

Two authors independently screened the title, abstracts, and full article texts to identify eligible studies and assess the risk of bias. Observational and interventional studies were included.

DATA ANALYSIS

A narrative synthesis approach was used to summarize the findings qualitatively.

RESULTS

From the search, 3059 publications were identified; of these, 8 studies were included in this systematic review. Three types of nutritional interventions were identified: food baskets (eg, energy, micronutrient- or macronutrient-enriched food support), nutritional advice and guidance, and incentives for buying foods. Although 5 studies reported that nutritional support significantly improved treatment adherence in patients with TB, 3 studies showed that nutritional support had no effect on TB treatment adherence.

CONCLUSIONS

Providing nutritional support may improve adherence to TB treatment. However, more well-powered, high-quality trials are warranted to demonstrate the effect of nutrition support on cost-effectively improving adherence to TB treatment.

Mindfulness-based cognitive therapy for adherence of immunosuppressive treatment in liver transplant recipients: A randomized controlled trial

OBJECTIVE

The aim of this study was to analyze the effects of mindfulness-based cognitive therapy on the adherence of liver transplant recipients to immunosuppressive therapy with a randomized controlled design.

METHOD

This randomized controlled trial was performed with 120 liver transplant recipients hospitalized at the liver transplant department of a research and practice hospital (n = 120). While we administered no intervention to the patients in the control group (n = 60), we provided Mindfulness-Based Cognitive Therapy to those in the experimental group (n = 60). We used the Mindful Attention Awareness Scale and the Immunosuppressant Therapy Adherence Scale to collect data. We utilized descriptive statistics, paired-samples t-tests, independent-samples t-tests, one-way analysis of variance, and chi-squared tests to analyze the data.

RESULTS

After the intervention, the immunosuppressive therapy adherence levels of the experimental group increased significantly (p < 0.01). On the other hand, the control group had significantly higher adherence to immunosuppressive therapy and significantly higher levels of mindfulness in the pretest phase than it did in the posttest phase (p < 0.01).

CONCLUSIONS

Complete adherence to immunosuppressive therapy is imperative for the prevention of graft rejection in liver transplant recipients. In our study, the experimental group equipped with enhanced mindfulness had higher adherence to immunosuppressive therapy. Therefore, the use of Mindfulness-Based Cognitive Therapy in the promotion of adherence to immunosuppressive therapy is recommended.

Statin initiation after myocardial infarction in patients with alcohol-related liver disease: A nationwide population-based study

BACKGROUND AND AIMS

Secondary prevention with statins improves clinical outcomes after myocardial infarction (MI). We aimed to compare odds of statin initiation after MI in patients with co-existing alcohol-related liver disease (ALD) to the general population, and the association between statin initiation and mortality in the patients with ALD.

METHODS

All statin-naïve patients with ALD and a first-time MI between 2006 and 2020 were identified from Swedish healthcare registers and matched for age, sex, and year of MI with up to ten ALD-free general population controls with a first-time MI. Logistic regression was used to estimate adjusted odds ratios (OR) for statin initiation within 30 days after MI for ALD patients versus controls. Cox regression was used in patients with ALD to compare mortality between statin initiators and non-initiators.

RESULTS

Of the 276 patients with a first-time MI and ALD, 206 (74.6%) were male, the median age was 67 (interquartile range 62-72), 151 (54.7%) had cirrhosis, and 62 (22.5%) had decompensated cirrhosis. 1769 matched controls were included. Initiation of statins was less common in ALD patients (50.0%) than controls (89.2%, adjusted OR = .15, 95% confidence interval [CI] = .10-.20). Among patients with ALD, statin initiators and non-initiators were followed for a median of 3.9 (interquartile range = 1.8-7.7) and 1.9 years (interquartile range = .5-4.4), respectively. Statin initiators had lower mortality than non-initiators (adjusted hazard ratio = .41, 95%CI = .28-.59).

CONCLUSIONS

Patients with ALD less often initiated statins after MI than the general population. Statin initiation was associated with improved survival, suggesting that patients with ALD might be undertreated following MI.

Single-pill combination for treatment of hypertension: Just a matter of practicality or is there a real clinical benefit?

Elevated blood pressure (BP) is the largest contributor to the incident cardiovascular disease worldwide. Despite explicit guideline recommendations for the diagnosis and management of hypertension, a large proportion of patients remain undiagnosed, untreated, or treated but uncontrolled. Inadequate BP control is associated with many complex factors including patient preference, physician's inertia, health systems disparities, and poor adherence to prescribed antihypertensive drug treatment. The primary driver for reduced cardiovascular morbidity and mortality is lowering of BP ''per se'' and not class effects of specific pharmacotherapies. The recent ESH guidelines recommend the use of four major classes of drugs including renin-angiotensin-aldosterone system (RAS) blockers (angiotensin receptor blockers (ARB) or angiotensin-converting enzyme inhibitors (ACEi)), calcium channel blockers (CCB), thiazide and thiazide-like diuretics, and betablockers. Initiation of treatment for hypertension with a two-drug regimen, preferably in a single pill combination (SPC), is recommended for most patients. Preferred combinations should comprise a RAS blocker (either an ACEi or an ARB) with a CCB or thiazide/thiazide-like diuretic. These strategies are supported by robust evidence that combination therapy produces greater BP reductions than monotherapy, reduces side effects of the individual components, improves therapeutic adherence and long-term persistence on treatment, and permits achievement of earlier BP control.

Effectiveness of eHealth Interventions in Improving Medication Adherence Among Patients With Cardiovascular Disease: Systematic Review and Meta-Analysis

BACKGROUND

Nonadherence to medication among patients with cardiovascular diseases undermines the desired therapeutic outcomes. eHealth interventions emerge as promising strategies to effectively tackle this issue.

OBJECTIVE

The aim of this study was to conduct a network meta-analysis (NMA) to compare and rank the efficacy of various eHealth interventions in improving medication adherence among patients with cardiovascular diseases (CVDs).

METHODS

A systematic search strategy was conducted in PubMed, Embase, Web of Science, Cochrane, China National Knowledge Infrastructure Library (CNKI), China Science and Technology Journal Database (Weipu), and WanFang databases to search for randomized controlled trials (RCTs) published from their inception on January 15, 2024. We carried out a frequentist NMA to compare the efficacy of various eHealth interventions. The quality of the literature was assessed using the risk of bias tool from the Cochrane Handbook (version 2.0), and extracted data were analyzed using Stata16.0 (StataCorp LLC) and RevMan5.4 software (Cochrane Collaboration). The certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach.

RESULTS

A total of 21 RCTs involving 3904 patients were enrolled. The NMA revealed that combined interventions (standardized mean difference [SMD] 0.89, 95% CI 0.22-1.57), telephone support (SMD 0.68, 95% CI 0.02-1.33), telemonitoring interventions (SMD 0.70, 95% CI 0.02-1.39), and mobile phone app interventions (SMD 0.65, 95% CI 0.01-1.30) were statistically superior to usual care. However, SMS compared to usual care showed no statistical difference. Notably, the combined intervention, with a surface under the cumulative ranking curve of 79.3%, appeared to be the most effective option for patients with CVDs. Regarding systolic blood pressure and diastolic blood pressure outcomes, the combined intervention also had the highest probability of being the best intervention.

CONCLUSIONS

The research indicates that the combined intervention (SMS text messaging and telephone support) has the greatest likelihood of being the most effective eHealth intervention to improve medication adherence in patients with CVDs, followed by telemonitoring, telephone support, and app interventions. The results of these network meta-analyses can provide crucial evidence-based support for health care providers to enhance patients' medication adherence. Given the differences in the design and implementation of eHealth interventions, further large-scale, well-designed multicenter trials are needed.

Leveraging Habits to Improve Adherence to Gout Medications: A Qualitative Study

OBJECTIVE

This study investigates patients' medication-taking routines and the feasibility of harnessing habit formation through context cues and rewards to improve medication adherence.

METHODS

Semistructured qualitative interviews with patients with gout from an urban health care system were conducted to explore typical medication-taking behavior, experiences using electronic pill bottles, barriers to adherence, existing context cues, and potential cues and rewards for habit-forming behavior. Medication-taking patterns were recorded for six weeks using electronic pill bottles before interviews to inform discussion. Transcribed interviews were analyzed to generate themes using codes developed by the study team, with representative quotations selected as illustrations.

RESULTS

We conducted interviews with 15 individuals (mean age 60.6 [SD 20.3] years, three women [20%], and nine White patients [60%]). Pill bottle-recorded adherence to urate-lowering therapy (ULT) was high (mean 0.91 [SD 0.10]), and one patient was experiencing an active gout flare. Five key themes emerged: (1) reasons for nonadherence, (2) internal and external motivations for adherence, (3) structured routines around taking medications, (4) rewards for good medication adherence, and (5) the role of pill cap technology in medication-taking.

CONCLUSION

The importance of a predictable, structured routine in which participants could incorporate their medication-taking behavior emerged as a key factor that promoted consistent adherence. Further, identifying context cues and reminders seemed to promote incorporation of medication-taking into routines. Therefore, habit-based interventions that use context cues to establish routines around medication-taking may be a feasible strategy to improve adherence in patients with chronic conditions such as gout.

Enhancing clinical service design for multimorbidity management: A comprehensive approach to joined-up care for diabetes, chronic kidney disease, and heart failure

BACKGROUND AND AIMS

Multimorbidity is becoming the norm rather than the exception, especially among the ageing population and people with lower socio-economic status. In addition to the rising healthcare cost, multimorbidity poses considerable difficulty in the delivery of adequate holistic care for affected patients.

METHODS

This review presents a discussion of the current barriers to delivering holistic care to people with multimorbidity and proposes a model of clinical care for people living with cardiovascular-kidney-metabolic (CKM) syndrome as an exemplar of a multimorbidity cluster.

RESULTS

Single organ/disease services may not be able to provide optimum care to people with multimorbidity due to the potential complex interactions between multiple disease symptoms and management. In addition, people with multimorbidity may be required to attend multiple appointments in different healthcare centres. This may negatively impact access to services due to time and financial burden. Other barriers include co-ordinating communication between healthcare professionals and reduced continuity of care. Optimising CKM health requires patient-centred care led by an interdisciplinary care team who ideally should possess CKM competencies utilising a shared care protocol to coordinate evidence-based care and use of telehealth to empower patients. Stakeholders and policymakers need to adapt new policy models to establish and enhance CKM care models by allocating funds and implementing frameworks for educational reforms.

CONCLUSIONS

A CKM service has the potential to increase the uptake of cardiac and renal protective medications as well as optimising metabolic care, increase capacity in both primary and secondary care, improve quality of life and clinical outcomes, reduce patient inconvenience, and importantly allow rapid translation of advances in cardiorenal metabolic diseases into clinical practice.

Managing cardiovascular risk factors in patients with chronic kidney disease: pharmacological and non-pharmacological interventions in the Copenhagen CKD Cohort

Background

Although cardiovascular morbidity and mortality are substantial in patients with chronic kidney disease (CKD), guideline-directed treatment of cardiovascular risk factors remains a challenge.

Methods

Observational, cross-sectional study including patients aged 30-75 years with CKD stage 1-5 without kidney replacement therapy from a tertiary hospital outpatient clinic. Data were obtained through patient interview, clinical examination, biochemical work-up, and evaluation of medical records and prescription redemptions. Guideline-directed treatment was evaluated as pharmacological interventions: antihypertensive and lipid-lowering therapy including adverse effects and adherence estimated as medication possession ratio (MPR); and non-pharmacological interventions: smoking status, alcohol consumption, body mass index (BMI), and physical activity.

Results

The cohort comprised 741 patients, mean age 58 years, 61.4% male, 50.6% CKD stage 3, 61.0% office blood pressure ≤140/90 mmHg. Antihypertensives were prescribed to 87.0%, median number of medications 2 (IQR 1;3), 70.1% received renin-angiotensin system inhibition, 25.9% reported adverse effects. Non-adherence (MPR < 80%) was present in 23.4% and associated with elevated blood pressure (OR 1.53 (95% CI 1.03;2.27)) and increased urinary albumin excretion, P < 0.001. Lipid-lowering treatment was prescribed to 54.0% of eligible patients, 11.1% reported adverse effects, and 28.5% were non-adherent, which was associated with higher LDL cholesterol, P = 0.036. Overall, 19.2% were current smokers, 16.7% overconsumed alcohol according to Danish health authority recommendations 69.3% had BMI ≥ 25 kg/m2, and 38.3% were physically active <4 hours/week. Among patients prescribed antihypertensives, 51.9% reported having received advice on non-pharmacological interventions.

Conclusions

Improved management of cardiovascular risk in patients with CKD entails intensified medical treatment and increased focus on patient adherence and non-pharmacological interventions.

Persistence to statin treatment: A cohort study in Lithuania

Cardiovascular diseases are the main causes of death, and statins can reduce the risk of major vascular events. Lithuania is among the European countries with the highest cardiovascular mortality despite a rapidly increasing use of statins. Previous reviews have shown the problem of poor patient adherence, but there are limited studies from Eastern European countries. The aim of this study was to evaluate treatment persistence in new users of statins in Lithuania and to investigate factors associated with persistence. Dispensed prescriptions from patients aged >18 years old initiated on statins in 2018-2019 were included, and data were obtained from a national health insurance fund. Persistence was assessed by the proportion of patients who still had statins dispensed 1 year after the first dispensing. Factors associated with persistence were assessed using logistic regression. A total of 104 726 patients (41.3% men) were initiated on statin treatment. Only 41% of them continued statin use 1 year after initiation. Factors associated with higher persistence rate were older age, higher dose of statin, use of other medicines and use of statins as secondary prevention. Low persistence to statin therapy needs to be recognized by healthcare workers, pharmacists and policy makers to address this problem.

Platelet function testing and clinical outcomes in peripheral arterial disease: Systematic review and narrative synthesis

OBJECTIVE

This systematic review aims to comprehensively assess the contemporary literature on platelet function testing (PFT) in individuals undergoing revascularization therapy for peripheral arterial disease (PAD). The goal is to identify whether PFT can aid in detecting antiplatelet resistance, predicting post-procedural thrombotic complications, and informing tailored treatment strategies.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a literature review was conducted using PubMed databases. Search terms included relevant medical subject headings (MeSH) terms. Eligible articles published in English between 1990 and 2023 were analyzed. Studies that examined PFT outcomes in patients with PAD after lower extremity revascularization were included.

RESULTS

Ten studies met the inclusion criteria. Various PFT methods were used, including thromboelastography with platelet mapping, multiplate analyzer, Cytochrome P450 2C19 testing, VerifyNow, corrected whole blood aggregometry, platelet function analyzer-100, and light transmission aggregometry. PFT identified individuals who were resistant or non-sensitive to antiplatelet therapy, with such patients facing increased risks of graft/stent thrombosis, amputation, and reintervention. However, substantial heterogeneity in surgical procedures, drug regimens, and testing methods was observed among the studies.

CONCLUSIONS

PFTs can play a crucial role in detecting resistance and non-sensitivity to antiplatelet drugs in patients with PAD post-revascularization. However, heterogeneity of data and methods underlines the need for standardized protocols and consensus-building among PFTs. Enhancing clinical utility and reliability could help optimize antiplatelet thromboprophylaxis, minimize thrombotic complications, and improve treatment strategies in vascular surgery. Further research is necessary to solidify the role of PFTs in guiding antiplatelet therapy post-revascularization in patients with PAD.

Impact of Guideline-Directed Drug Therapy after ST-Elevation Myocardial Infarction on Outcome in Young Patients-Age and Sex-Specific Factors

Background: Specifically young women are at risk for a poor outcome after ST-elevation myocardial infarction (STEMI). We aimed to investigate sex- and age-specific differences in outcome and associate these results with adherence to a guideline-directed optimal medical therapy (OMT). Methods: Administrative insurance data (≈26 million insured) were screened for patients aged 18-60 years with STEMI. Patient demographics, details on in-hospital treatment, adherence to OMT and its effect on mortality were assessed. Adherence to OMT was analyzed using multistate models and an association of those with death was fitted using multivariable Cox regression models with time-dependent co-variables. Results: Overall, 59,401 patients (19.3% women), median age 52 (interquartile range 48, 56) presented with STEMI. Female sex was associated with a poor outcome early after STEMI (90-day mortality: odds ratio 1.22, 95% confidence interval (CI) 1.12-1.32, p < 0.001). Overall survival was reduced in women compared to same-aged men. The ten-year survival rate was 19.7% (18.1-21.2%) versus 19.6% (18.9-20.4%) in men (p < 0.001). Although long-term drug adherence was low, its intake was associated with a better outcome. Specifically younger women showed a markedly lower mortality when on OMT (hazard ratio (HR) 0.22 (95% CI 0.19-0.26) versus HR 0.31 (95% CI 0.28-0.33) in men, pint < 0.001). Conclusions: Specifically young women were at risk for a poor outcome in the early phase after STEMI. Although long-term adherence to OMT was low, it was generally associated with a lower mortality, specifically in women. Our findings emphasize on early and long-term preventive measures in all patients after STEMI.

The Nurses' Role in the Cardiac Rehabilitation Team: Data From the Perfect-CR Study

BACKGROUND

Nurses constitute a central profession in the cardiac rehabilitation (CR) team delivering comprehensive CR to individuals with cardiovascular disease. We aimed to identify specific components reflecting the nurses' role in the CR team associated with attainment of risk factor targets post myocardial infarction.

METHODS

Center-level data (n = 78) was used from the Perfect-CR study, in which structure and processes applied at CR centers in Sweden (including details on the nurses' role) were surveyed. Patient-level data (n = 6755) was retrieved from the SWEDEHEART registry. Associations between structure/processes and target achievement for systolic blood pressure (BP) (<140 mm Hg) and low-density lipoprotein cholesterol (LDL-C, <1.8 mmol/L) at 1 year post myocardial infarction were assessed using logistic regression.

RESULTS

Structure and processes reflecting nurses' autonomy and role in the CR team associated with patients achieving systolic BP and/or LDL-C targets included the following: nurses having treatment algorithms to adjust BP medication (odds ratio [95% confidence interval]: systolic BP, 1.22 [1.05-1.42]; LDL-C, 1.17 [1.03-1.34]) and lipid-lowering medication (systolic BP, 1.14 [1.00-1.29]; LDL-C, 1.17 [1.05-1.30]), patients having the same nurse throughout follow-up (systolic BP, 1.07 [1.03-1.11]; LDL-C, 1.10 [1.06-1.14]), number of follow-up hours with a nurse (systolic BP, 1.13 [1.07-1.19]), having regular case rounds to discuss patient cases during follow-up (LDL-C, 1.22 [1.09-1.35]), and nurses having training in counseling methods (systolic BP, 1.06 [1.03-1.10]).

CONCLUSION

Components reflecting CR nurses' autonomy and role in the team are of importance for patients attaining risk factor targets post myocardial infarction. The results could provide guidance for optimizing nurses' competence and responsibilities within the CR team to improve patient care.

Drug stewardship in chronic kidney disease to achieve effective and safe medication use

People living with chronic kidney disease (CKD) often experience multimorbidity and require polypharmacy. Kidney dysfunction can also alter the pharmacokinetics and pharmacodynamics of medications, which can modify their risks and benefits; the extent of these changes is not well understood for all situations or medications. The principle of drug stewardship is aimed at maximizing medication safety and effectiveness in a population of patients through a variety of processes including medication reconciliation, medication selection, dose adjustment, monitoring for effectiveness and safety, and discontinuation (deprescribing) when no longer necessary. This Review is aimed at serving as a resource for achieving optimal drug stewardship for patients with CKD. We describe special considerations for medication use during pregnancy and lactation, during acute illness and in patients with cancer, as well as guidance for the responsible use of over-the-counter drugs, herbal remedies, supplements and sick-day rules. We also highlight inequities in medication access worldwide and suggest policies to improve access to quality and essential medications for all persons with CKD. Further strategies to promote drug stewardship include patient education and engagement, the use of digital health tools, shared decision-making and collaboration within interdisciplinary teams. Throughout, we position the person with CKD at the centre of all drug stewardship efforts.

Improving medication adherence in cardiovascular disease

Non-adherence to medication is a global health problem with far-reaching individual-level and population-level consequences but remains unappreciated and under-addressed in the clinical setting. With increasing comorbidity and polypharmacy as well as an ageing population, cardiovascular disease and medication non-adherence are likely to become increasingly prevalent. Multiple methods for detecting non-adherence exist but are imperfect, and, despite emerging technology, a gold standard remains elusive. Non-adherence to medication is dynamic and often has multiple causes, particularly in the context of cardiovascular disease, which tends to require lifelong medication to control symptoms and risk factors in order to prevent disease progression. In this Review, we identify the causes of medication non-adherence and summarize interventions that have been proven in randomized clinical trials to be effective in improving adherence. Practical solutions and areas for future research are also proposed.

Tafamidis 61 mg Patient Characteristics and Persistency? A Retrospective Analysis of German Statutory Health Insurance Data (IQVIA™ LRx)

INTRODUCTION

Tafamidis is the first drug approved by the European Commission for the treatment of wild-type or hereditary transthyretin amyloid cardiomyopathy (ATTR-CM) in adults to reduce cardiovascular mortality and cardiovascular-related hospitalization. Real-world treatment patterns of tafamidis 61 mg in Germany are not well studied in patients with ATTR-CM.

METHODS

This was a non-interventional, retrospective, observational cohort study of adult patients in Germany based on the IQVIA pharmacy claims database (IQVIA™ LRx). Patients included in the analysis were statutory insured and received at least one prescription of tafamidis 61 mg between March 1, 2020 and August 31, 2022. Treatment adherence was analyzed using the modified medical possession ratio (mMPR) and proportion of days covered (PDC).

RESULTS

Overall, 1565 adult patients received at least one tafamidis prescription in the study period. Their mean age was 78.3 years, 82.4% were male, and 23.2% were treated by a cardiologist. Persistency rates for patients treated with tafamidis 61 mg were high: 78.0% for 12 months and 65.1% for 24 months after treatment initiation. Patients also had high adherence rate on filling their prescriptions on time: 94.6% and 90.5% of patients had adherence rates of at least 80%, measured by mMPR and PDC, respectively.

CONCLUSIONS

In the IQVIA™ LRx database, patients prescribed tafamidis 61 mg in Germany displayed high adherence and persistency rates, which suggest good drug tolerability and ease of use.

Effects of a medication adherence app among medically underserved adults with chronic illness: a randomized controlled trial

For individuals living with a chronic illness who require use of long-term medications, adherence is a vital aspect of successful symptom management and outcomes. This study investigated the effect of a smartphone app on adherence, self-efficacy, knowledge, and medication social support in a medically underserved adult population with various chronic illnesses. Participants were randomized to a group who used the app for one month or a control group provided with a printed medication list. Compared to the control group, participants receiving the intervention had significantly greater medication adherence (Cohen's d = -0.52, p = .014) and medication self-efficacy (Cohen's d = 0.43, p = .035). No significant effects were observed related to knowledge or social support. The findings suggest use of the app could positively impact chronic disease management in a medically underserved population in the United States.

Tafamidis medication adherence and persistence in patients with transthyretin amyloid cardiomyopathy in Japan

AIMS

This study aimed to describe baseline characteristics and adherence among patients with transthyretin amyloid cardiomyopathy (ATTR-CM) treated with tafamidis (VYNDAQEL®) in Japan using the Japanese Medical Data Vision (MDV) database.

METHODS AND RESULTS

This study was a non-interventional, retrospective cohort study of adult (≥18 years old) patients in the Japanese MDV claims database diagnosed with ATTR-CM and with at least two tafamidis prescriptions of dose strength 4 × 20 mg/day between 1 March 2019 and 31 August 2021. The date of the first prescription was defined as the index date, with follow-up time defined as the time between the first and last prescription plus the days' supply from the last refill. Baseline characteristics were assessed during a 12 month pre-index period. Adherence was measured using two metrics: (i) the modified medication possession ratio (mMPR), calculated by taking the sum of days supplied for all fills within the follow-up period, divided by the number of days of follow-up, and reported as a percentage, with patients classified as adherent with an mMPR of ≥80%, and (ii) the proportion of days covered (PDC), calculated by taking the total number of days' supply dispensed during the follow-up period divided by the number of days of follow-up, adjusting for any days' supply overlap. A total of 210 patients were identified; the mean (standard deviation) age of the cohort was 77 (5.9) years, and the majority (89%) were male. The most common baseline cardiovascular comorbidities were heart failure (85%), ischaemic heart disease (66%), hypertensive diseases (49%), and diabetes (35%); 75% of patients received heart failure medications in the 12 months prior to index, with the most common being beta-blockers (49%), diuretics (48%), angiotensin receptor blockers (30%), angiotensin-converting enzyme inhibitors (22%), and sodium-glucose cotransporter-2 inhibitors (8.1%). Over an average 14 month follow-up, mean mMPR was 96% with a median of 100% [inter-quartile range (IQR): 97-101%]; 93% of patients were adherent (defined as an mMPR ≥ 80%). In the same follow-up period, mean PDC was 93.6% with a median of 99% (IQR: 93-100%). Persistence was high with 78% of patients having a 0 day gap between prescription refills.

CONCLUSIONS

This study found high adherence rates to tafamidis in this real-world Japanese patient population. Adherence rates in this study were similar to those reported by the tafamidis clinical trial and a previously published US commercial claims adherence analysis. Further studies should be conducted to assess the impact of real-world adherence on real-world outcomes.

Management of lipid variables in primary cardiovascular prevention: A position paper from the Heart, Vessels and Metabolism Group of the French Society of Cardiology

Low-density lipoprotein cholesterol has been established as a powerful cardiovascular risk factor; its reduction provides a clinical benefit in primary cardiovascular prevention, irrespective of the characteristics of the patients treated. It is useful to tailor low-density lipoprotein cholesterol targets according to the magnitude of cardiovascular risk (low, high or very high) in order to reduce the cardiovascular risk as fully as possible. In order to provide a uniform approach, it is necessary to propose recommendations for good practice, defining strategies for reducing low-density lipoprotein cholesterol. It is also necessary to know their merits, to analyse their practical limits and to propose adaptations, taking into account limitations and national specifics. This position paper aims to analyse the contribution and limits, as well as the adaptation to French practice, of 2019 and 2021 European Society of Cardiology recommendations for the management of lipid variables and cardiovascular prevention.

Extemporaneous combination therapy with nebivolol/amlodipine for the treatment of hypertension: a real-world evidence study in Europe

OBJECTIVE

The investigation of the real-world use of the extemporaneous combination of nebivolol and amlodipine (NA-EXC) in adult patients diagnosed with hypertension in Europe.

METHODS

Retrospective analysis of data extracted from seven databases of patient medical records and prescriptions from Italy, Germany, France, Hungary, and Poland, to determine the prevalence and incidence of NA-EXC use and to estimate the number of patients potentially eligible for a single-pill combination of the two antihypertensives. Secondary objectives included: the description of the population of NA-EXC users and the assessment of their adherence to treatment based on the proportion of days covered.

RESULTS

The use of NA-EXC was found to be common in Europe and ranged between 2.9% to 9.9% of all patients identified in the databases with a prescription of nebivolol and/or amlodipine. The estimated numbers of patients potentially eligible in 2019 for a single-pill combination of nebivolol and amlodipine in Italy and Germany were, respectively, 178,133 and 113,240. Users of NA-EXC were mostly aged 70-79 years, had metabolic disorders and other comorbidities; >70% of them had received ≥2 concomitant medications before starting NA-EXC. Adherence to NA-EXC was defined as high only in 15.6% to 35% of patients.

CONCLUSIONS

The extemporaneous combination of nebivolol and amlodipine is commonly prescribed in Europe, however adherence to the therapy is poor. The development of a single-pill combination of nebivolol and amlodipine may improve adherence by reducing the number of pills administered to patients and thus simplifying treatment regimens.

Validation of the Novel Web-Based Application HUMTELEMED for a Comprehensive Assessment of Cardiovascular Risk Based on the 2021 European Society of Cardiology Guidelines

Background and aims: SCORE2/SCORE2-OP cardiovascular risk (CVR) charts and online calculators do not apply to patients with comorbidities, target organ damage, or atherosclerotic cardiovascular disease, for whom the assessment relies on the conventional consultation of the 2021 ESC guidelines (qualitative approach). To simplify the CVR evaluation, we developed an integrated multi-language and free-to-use web application. This study assessed the agreement between the conventional method versus our web app. Methods: A cross-sectional study was carried out on 1306 consecutive patients aged 40+ years referred to our center for the diagnosis and management of hypertension and dyslipidemia. Two double-blind operators performed the CVR assessment and classified each patient into low-moderate-, high-, and very-high-risk categories by using the conventional method (SCORE2/SCORE2-OP charts and consultation of the 2021 ESC guidelines) and the web app. The Kappa statistics were used to compare the two methods. Results: The mean age was 60.3 ± 11.9 years, with male prevalence (51.4%). Patients in primary prevention were 77.0%. According to the SCORE2/SCORE2-OP charts and 2021 ESC guideline consultation, the CVR was low-moderate in 18.6% (n° 243), high in 36.8% (n° 480), and very high in 44.6% (n° 583). According to the web app, individual CVR was low-moderate in 19.5% (n° 255), high in 35.4% (n° 462), and very high in 45.1% (n° 589). The two methods strongly agreed (Kappa = 0.960, p < 0.001), with a 97.5% concordance. Conclusions: our application has excellent reliability in a broad "real life" population and may help non-expert users and busy clinicians to assess individual CVR appropriately, representing a free-to-use, simple, time-sparing and widely available alternative to the conventional CVR evaluation using SCORE2/SCORE2-OP and 2021 ESC guideline charts.

Treatment adherence in patients without ST-elevation acute coronary syndrome

BACKGROUND

Despite progress during the last decades, patients with coronary artery disease (CAD) remain with a high residual risk due to multiple reasons. Optimal medical treatment (OMT) provides a decrease of recurrent ischemic events after acute coronary syndrome (ACS). Therefore, treatment adherence results crucial to reduce further outcomes after the index event. No recent data are available in Argentinian population; the main objective of our study was to evaluate the adherence at 6 and 15 months in post non-ST elevation acute coronary syndrome (NST-ACS) consecutive patients. Secondary objective was to evaluate the relationship of adherence with 15-month events.

METHODS

A prespecified sub-analysis in the prospective registry Buenos Aires I was performed. The adherence was evaluated using the modified Morisky-Green Scale.

RESULTS

A number of 872 patients had information about adherence profile. Of them 76.4% were classified as adherents at month 6 and 83.6% at 15 (P=0.06). We did not find any difference in baseline characteristic between the adherent and non-adherent patients at 6 months. The adjusted analysis showed that non-adherent patients had a rate of ischemic events at 15th month of 20% (27/135) vs. 11.5% (52/452) in adherent patients (P=0.001). The bleeding events defined were of 3.6% in the non-adherent group vs. 5% in the adherent group without a statistical difference (P=0.238).

CONCLUSIONS

Adherence to treatment is still a major issue as almost 25% of patients should be considered as non-adherent to OMT. No clinical predictor of this phenomenon was identified but our criteria were not exhaustive. Good adherence to treatment was highly associated to a reduction of ischemic events, whereas no impact on bleeding events was found. These data support a better network and collaboration with shared decision between healthcare professionals with patients and family members to improve acceptance and adherence to optimal medical strategies.

Hypothyroidism Presenting Atypically as an Isolated Pericardial and Pleural Effusion: A Case Report

Hypothyroidism is an endocrine disorder characterized by low thyroid hormone levels, which commonly presents as fatigue, cold intolerance, constipation, poor memory and/or concentration, and weight gain. Common signs of hypothyroidism include bradycardia, electrocardiograph changes, a lower basal temperature, a slower relaxation phase of deep tendon reflexes, and swelling of the extremities. Hypothyroidism is diagnosed with labs showing high thyroid-stimulating hormone levels and low free thyroxine. Hypothyroidism may present as a pericardial or pleural effusion, with the incidence of each being unknown. The paucity of information regarding the incidence of pericardial and pleural effusions in hypothyroidism may be due to effusions being an atypical complication of a common endocrine disorder. Hypothyroidism, including in cases of pericardial or pleural effusions, is typically treated with thyroid hormone replacement therapy, usually in the form of levothyroxine. Hemodynamic compromise may necessitate pericardiocentesis or pleurocentesis. In this case report, we present an atypical presentation of hypothyroidism that is characterized by an isolated pericardial and pleural effusion in a patient with post-thyroidectomy hypothyroidism who was non-adherent to levothyroxine. We discuss the pathophysiology of pleural and pericardial effusions in thyroid disease, which is thought to involve increased capillary permeability and changes in oncotic pressure related to albumin. We also review treatment strategies regarding pericardial and pleural effusions in hypothyroidism.

Non adherence to lipid-lowering therapy and strategies to improve adherence

Lipid lowering therapies is well-established to prevent cardiovascular events in adults with dyslipidemia and multiple risk factors. However, global clinical usage of LLT,particularly statins remains suboptimal, with adherence low rates for primary prevention and secondary prevention. Low adherence is influenced by concerns about side effects, misconceptions about benefits. Patients often discontinue statins due to perceived side effects, despite clinical trials showing no increase in symptoms compared to placebo. Poor understanding of statin benefits, doubts about their necessity, and suspicions of over prescription contribute to nonadherence, which is often amplified by negative portrayal of LLT specialy statins on social media. Strategies to improve adherence include addressing patient concerns, enhancing physician-patient communication, and increasing patient education. Optimizing statin usage and reducing the burden of cardiovascular disease necessitates addressing patient perceptions and improving communication between healthcare providers and patients.

The Association between Deductibles and Cardiovascular Medication Adherence: A Retrospective Inception Cohort Study

OBJECTIVE

Drug non-adherence in primary preventive cardiovascular therapy is one of the most important modifiable drivers of cardiovascular events. The effect of deductibles in healthcare cost-sharing plans (the amount that has to be paid for healthcare services before the insurance company starts to pay) on such non-adherence in a European setting is unknown. Therefore, we estimated the association between deductibles and the adherence to primary preventive antihypertensive and antihyperlipidemic medication.

METHODS

Using the claims database of Menzis Health Insurer in the Netherlands, we applied ordered beta regression mixed modelling to estimate the association between deductibles and adherence taking several demographic and social-economic factors, repeated measurements and within-patient variation into account.

RESULTS

All in all, 106,316 patients starting primary preventive antihypertensive or antihyperlipidemic monotherapy were eligible for analysis. At index date, mean age of the study population was 58 years and 52% were male. Reaching the deductible limit and no need to pay for medication anymore increased the adherence [relative adherence ratio (RAR) 1.03, 95% confidence interval (95% CI): 1.00-1.05] for antihyperlipidemic therapy and 1.02 (95% CI: 1.00-1.04) for antihypertensive therapy. A larger deductible amount decreases the adherence of antihyperlipidemic and antihypertensive therapy (RAR 0.83; 95% CI: 0.69-1.00 and RAR 0.85, 95% CI: 0.74-0.98, respectively).

CONCLUSION

Independent of other risk factors for non-adherence, presence of deductibles in health insurance is associated with a small negative effect on the adherence to both primary preventive antihypertensive as well as antihyperlipidemic therapy. Further study is needed on the potential health-economic consequences.

Therapy and guideline adherence at a multidisciplinary hypertension clinic: A prospective, observational study

BACKGROUND

Hypertension is highly prevalent and remains one of the most frequent and preventable causes of cardiovascular morbidity and mortality. Yet, suboptimal blood pressure control is common. Hypertension clinics might play an important role in improving target attainment, by targeting drug therapy adherence, improving guideline compliance and by involving pharmacists.

OBJECTIVES

We aimed to characterize patient drug therapy adherence, prescriber guideline compliance and pharmacist interventions at the hypertension clinic.

METHODS

A prospective observational study was performed at the hypertension clinic of a large, academic hospital. Adult Dutch-speaking patients were eligible for inclusion. Following data were collected: patient demographics, medication use, patient adherence to prescribed antihypertensive drug therapies according to the BAASIS tool and prescriber compliance to the 2018 European Society of Cardiology (ESC) hypertension guidelines.

RESULTS

A cohort of 108 patients was included with 51.9% male and aged 65 (IQR: 52-75) years. In total, 104 patients took at least 1 antihypertensive drug and 46 patients (44.2%) were classified as non-adherent with regard to their antihypertensive treatment; 82 patients (78.8%) had suboptimal blood pressure control. Compliance with the ESC guidelines was 66.3% prior to the consultation at the clinic and significantly increased to 77.9% thereafter (p = 0.0015). The clinical pharmacist performed a medication review for 27 patients with a total of 44 recommendations and an acceptance rate of 59.1%.

CONCLUSION

A visit to the multidisciplinary hypertension clinic improved prescriber guideline compliance and the use of single pill combinations. Involvement of a clinical pharmacist could be beneficial to further improve patient drug therapy adherence and guideline compliance.

High platelet adrenergic activity and concomitant activation of the pituitary/medullar axis as alarming laboratory parameters in ACS survivors-the STRESS-AMI study

Introduction

Kinetics of stress-related biological parameters were determined in acute coronary syndrome (ACS) patients undergoing complex cardiovascular rehabilitation.

Methods

We determined platelet functionality in the absence/presence of a selective alpha-2 adrenergic receptor inhibitor, atipemazole parallel with salivary cortisol levels at enrolment, and at 3- and 12-months follow-up in 75 ACS patients with percutaneous coronary intervention.

Results

Pharmacological/non-pharmacological secondary prevention methods have been efficiently applied. Baseline aggregometry indicated platelet hyperactivity, decreasing gradually and being significantly reduced late, at 12 months (p < 0.05). Cortisol levels followed similar kinetics (p < 0.05). Baseline epinephrine-induced aggregations (EIA) significantly correlated with most of the other platelet agonists, even at subsequent time-points. Patients with upper-quartile EIA at enrolment (EIA-UQ) had significantly higher ADP- and collagen-induced aggregations at enrolment, at 3- and 12-months follow-up as well, indicating that high adrenergic response in the acute phase is accompanied by general platelet hyperactivity and predicts sustained platelet activation. In the EIA-UQ group higher cardiac biomarker release, elevated C-reactive protein and cortisol levels, and lower baseline left ventricular ejection fraction were detected.Atipemazole significantly reduced platelet aggregation induced by several platelet agonists, being most potent and comparable to full in vitro P2Y12 inhibition on collagen-induced aggregations (p < 0.05), indicating that catecholamines might serve as promt/long-term modulators of platelet function.

Discussion

Despite effective CCR programme and dual antiplatelet therapy, prolonged activation of sympathetic neuroendocrine system and general platelet hyperactivity can be detected up to one year in ACS patients with high adrenergic platelet activity. Moreover, initial high adrenergic activity is accompanied by clinical parameters associated to increased cardiovascular risk, therefore early identification of these patients might support complex optimal long-term therapy.

Adherence to Medications in Patients with Ischaemic Heart Disease in Oman

Objectives

This study aimed to evaluate the level of adherence to medication among patients with ischaemic heart disease (IHD) in Oman and assess the related factors.

Methods

This cross-sectional questionnaire-based study among patients with IHD attending the outpatient clinic at Sultan Qaboos University Hospital, Muscat, Oman, was performed between January and December 2021.

Results

A total of 105 patients (mean age = 49.9 ± 11.1 years, 78.1% male) were recruited. Most of the patients (80%) reported taking the medications by themselves; 77 (73.3%) patients said that over the preceding 2 weeks, they had missed at least 3 doses of their medication. The reasons for missing the medications included forgetting (100%), having to take too many tablets (57%), feeling that the tablets are not effective (48%) and having to take the tablets too often each day (23%). The factors responsible for patients failing to take medications could not be identified.

Conclusion

Medication adherence was low among patients with IHD in Oman, with high pill burden being the most common reason for non-adherence. Physicians must bear this in mind when reviewing patients.

The role of adherence in patients with chronic diseases

In the long-term management of chronic diseases, adherence and persistence to prescribed medications are continuous challenges in order to obtain all the potential benefits of drug therapies. Suboptimal drug adherence and discontinuations of therapies remain the most frequent reasons why several diseases are poorly controlled in the population. One the main issue is that physicians are relatively limited in time and tools to detect patients with a poor adherence. The present review discusses present and future strategies that are now available or are being developed to detect and to support adherence in patients with chronic diseases and provides some simple clues to identify patients at high risk of discontinuation in the clinic.

A Retrospective Observational Real-Word Analysis of the Adherence, Healthcare Resource Consumption and Costs in Patients Treated with Bisoprolol/Perindopril as Single-Pill or Free Combination

INTRODUCTION

The present real-world analysis aims to compare the drug utilization, hospitalizations and direct healthcare costs related to the use of single-pill combination (SPC) or free-equivalent combination (FEC) of perindopril and bisoprolol (PER/BIS) in a large Italian population.

METHODS

This observational retrospective analysis was based on administrative databases covering approximately 7 million subjects across Italy. All adult subjects receiving PER/BIS as SPC or FEC between January 2017-June 2020 were included. Subjects were followed for 1 year after the first prescription of PER/BIS as FEC (± 1 month) or SPC. Before comparing the SPC and FEC cohorts, propensity score matching (PSM) was applied to balance the baseline characteristics. Drug utilization was investigated as adherence (defined by the proportion of days covered, PDC) and persistence (evaluated by Kaplan-Meier curves). Hospitalizations and mean annual direct healthcare costs (due to drug prescriptions, hospitalizations and use of outpatient services) were analyzed during follow-up.

RESULTS

The original cohort included 11,440 and 6521 patients taking the SPC and FEC PER/BIS combination, respectively. After PSM, two balanced SPC and FEC cohorts of 4688 patients were obtained (mean age 70 years, approximately 50% male, 24% in secondary prevention). The proportion of adherent patients (PDC ≥ 80%) was higher for those on SPC (45.5%) than those on FEC (38.6%), p < 0.001. The PER/BIS combination was discontinued by 35.8% of patients in the SPC cohort and 41.7% in the FEC cohort (p < 0.001). The SPC cohort had fewer cardiovascular (CV) hospitalizations (5.3%) than the free-combination cohort (7.4%), p < 0.001. Mean annual total healthcare costs were lower in the SPC (1999€) than in the FEC (2359€) cohort (p < 0.001).

CONCLUSION

In a real-world setting, patients treated with PER/BIS SPC showed higher adherence, lower risk of drug discontinuation, reduced risk of CV hospitalization, and lower healthcare costs than those on FEC of the same drugs.

Non-compliance with medical recommendations results in delayed hospitalization and poorer prognosis in patients with cerebral ischemic stroke in Poland: Non-compliance effects on post-ischemic stroke prognosis

OBJECTIVES

This study aimed to reveal and analyze the causes of delays in reaching the hospital of patients with cerebral ischemic stroke and to assess their clinical picture.

MATERIAL AND METHODS

The study group included 161 patients with stroke, who reported to the hospital beyond the thrombolytic treatment therapeutic window. The control group consisted of 85 patients recruited consecutively with stroke who received thrombolytic treatment per eligibility criteria. Laboratory and medical imaging tests essential for neurological condition assessment were conducted in the study group. Control group research was based on retrospective analysis of medical records.

RESULTS

The rate of deaths during hospitalization was lower in the control group (4.7%) compared to the study group (14.9%). In the study group, more patients (16.8%) admitted to non-compliance with medical recommendations than in the control group (5.9%). There were no statistically significant differences in nicotinism and alcohol dependence syndrome frequency between both groups.

CONCLUSIONS

Based on each group inclusion criteria, a lower mortality rate in the control group indicates a crucial role of the therapeutic window in cerebral stroke treatment. Analysis of reasons for delay points out that efficient prophylaxis is the education of patients with stroke risk factors and their families.

Efficacy of eHealth Technologies on Medication Adherence in Patients With Acute Coronary Syndrome: Systematic Review and Meta-Analysis

BACKGROUND

Suboptimal adherence to cardiac pharmacotherapy, recommended by the guidelines after acute coronary syndrome (ACS) has been recognized and is associated with adverse outcomes. Several randomized controlled trials (RCTs) have shown that eHealth technologies are useful in reducing cardiovascular risk factors. However, little is known about the effect of eHealth interventions on medication adherence in patients following ACS.

OBJECTIVE

The aim of this study is to examine the efficacy of the eHealth interventions on medication adherence to selected 5 cardioprotective medication classes in patients with ACS.

METHODS

A systematic literature search of PubMed, Embase, Scopus, and Web of Science was conducted between May and October 2022, with an update in October 2023 to identify RCTs that evaluated the effectiveness of eHealth technologies, including texting, smartphone apps, or web-based apps, to improve medication adherence in patients after ACS. The risk of bias was evaluated using the modified Cochrane risk-of-bias tool for RCTs. A pooled meta-analysis was performed using a fixed-effect Mantel-Haenszel model and assessed the medication adherence to the medications of statins, aspirin, P2Y12 inhibitors, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, and β-blockers.

RESULTS

We identified 5 RCTs, applicable to 4100 participants (2093 intervention vs 2007 control), for inclusion in the meta-analysis. In patients who recently had an ACS, compared to the control group, the use of eHealth intervention was not associated with improved adherence to statins at different time points (risk difference [RD] -0.01, 95% CI -0.03 to 0.03 at 6 months and RD -0.02, 95% CI -0.05 to 0.02 at 12 months), P2Y12 inhibitors (RD -0.01, 95% CI -0.04 to 0.02 and RD -0.01, 95% CI -0.03 to 0.02), aspirin (RD 0.00, 95% CI -0.06 to 0.07 and RD -0.00, 95% CI -0.07 to 0.06), angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (RD -0.01, 95% CI -0.04 to 0.02 and RD 0.01, 95% CI -0.04 to 0.05), and β-blockers (RD 0.00, 95% CI -0.03 to 0.03 and RD -0.01, 95% CI -0.05 to 0.03). The intervention was also not associated with improved adherence irrespective of the adherence assessment method used (self-report or objective).

CONCLUSIONS

This review identified limited evidence on the effectiveness of eHealth interventions on adherence to guideline-recommended medications after ACS. While the pooled analyses suggested a lack of effectiveness of such interventions on adherence improvement, further studies are warranted to better understand the role of different eHealth approaches in the post-ACS context.

Batteryless implantable device with built-in mechanical clock for automated and precisely timed drug administration

Adherence to medication plays a crucial role in the effective management of chronic diseases. However, patients often miss their scheduled drug administrations, resulting in suboptimal disease control. Therefore, we propose an implantable device enabled with automated and precisely timed drug administration. Our device incorporates a built-in mechanical clock movement to utilize a clockwork mechanism, i.e., a periodic turn of the hour axis, enabling automatic drug infusion at precise 12-h intervals. The actuation principle relies on the sophisticated design of the device, where the rotational movement of the hour axis is converted into potential mechanical energy and is abruptly released at the exact moment for drug administration. The clock movement can be charged either automatically by mechanical agitations or manually by winding the crown, while the device remains implanted, thereby enabling the device to be used permanently without the need for batteries. When tested using metoprolol, an antihypertensive drug, in a spontaneously hypertensive animal model, the implanted device can deliver drug automatically at precise 12-h intervals without the need for further attention, leading to similarly effective blood pressure control and ultimately, prevention of ventricular hypertrophy as compared with scheduled drug administrations. These findings suggest that our device is a promising alternative to conventional methods for complex drug administration.

Effect of a Medication Adherence Mobile Phone App on Medically Underserved Patients with Chronic Illness: Preliminary Efficacy Study

BACKGROUND

Medication adherence is vital in the treatment of patients with chronic illness who require long-term medication therapies to maintain optimal health. Medication adherence, a complex and widespread problem, has been difficult to solve. Additionally, lower-income, medically underserved communities have been found to have higher rates of inadequate adherence to oral medications. Even so, this population has been underrepresented in studies using mobile medication adherence app interventions. Federally qualified health centers provide care for medically underserved populations, defined as communities and populations where there is a demonstrable unmet need for health services. These centers have been reporting an increase in a more complex chronic disease population. Including medically underserved individuals in mobile health studies provides opportunities to support this disproportionately affected group, work toward reducing health disparities in access to health care, and understand barriers to mobile health uptake.

OBJECTIVE

The aim of this preliminary efficacy study was to evaluate the effects and feasibility of a commercially available medication adherence app, Medisafe, in a medically underserved adult population with various chronic illnesses seeking care in a federally qualified health center.

METHODS

Participants in this single-arm pre-post intervention preliminary efficacy study (N=10) completed a baseline survey, used the app for 2 weeks, and completed an end-of-study survey. The primary outcome measures were medication adherence and medication self-efficacy. Feedback on the use of the app was also gathered.

RESULTS

A statistically significant median increase of 8 points on the self-efficacy for adherence to medications scale was observed (P=.03, Cohen d=0.69). Though not significant, the adherence to refills and medications scale demonstrated a median change of 2.5 points in the direction of increased medication adherence (P=.21, Cohen d=0.41). Feedback about the app was positive.

CONCLUSIONS

Use of the Medisafe app is a viable option to improve medication self-efficacy and medication adherence in medically underserved patients in an outpatient setting with a variety of chronic illnesses.

A review of polypills for the prevention of atherosclerotic cardiovascular disease

Atherosclerotic cardiovascular disease (ASCVD) is a prevalent chronic condition managed through pharmacotherapy targeting modifiable risk factors. However, ASCVD patients often face poor medication adherence due to a high pill burden from multiple oral drugs, contributing to cardiovascular events. Recent evidence indicates that polypills combining antihypertensive and statin medications effectively control risk factors and improve adherence in various ASCVD risk patients. Randomized clinical trials demonstrate polypill efficacy in reducing major cardiovascular events, making them a convenient strategy for both established ASCVD patients and those without ASCVD. These positive results encourage the incorporation of polypills into comprehensive cardiovascular prevention programs, particularly for socio-economically vulnerable populations. Nevertheless, barriers remain, such as unclear regulatory approval pathways and physician hesitancy. Despite challenges, the benefits of fixed-dose combinations are evident and should be encouraged for secondary and primary prevention, especially in high-risk categories. Technological advancements could further support the successful integration of polypills in clinical practice. This review discusses the evidence, challenges, and perspectives of polypills, emphasizing their potential impact on cardiovascular disease management.

Are breast cancer patients with suboptimal adherence to cardiovascular treatment more likely to discontinue adjuvant endocrine therapy? Competing risk survival analysis in a nationwide cohort of postmenopausal women

BACKGROUND

High rates of discontinuation undermine the effectiveness of adjuvant endocrine therapy (AET) among hormone-receptive breast cancer patients. Patient prognosis also relies on the successful management of cardiovascular risk, which affects a high proportion of postmenopausal women. As with AET, adherence with cardiovascular drugs is suboptimal. We examined whether patient adherence with cardiovascular drugs was associated with the rate of AET discontinuation in a French nationwide claims database linked with hospitalisation data.

METHODS

We identified postmenopausal women starting AET between 01/01/2016 and 31/12/2020 and taking at least two drugs for the primary prevention of cardiovascular disease (antihypertensive drugs, lipid-lowering drugs and platelet aggregation inhibitors) before AET initiation. Adherence was assessed for each drug class by computing the proportion of days covered. Women were categorised as fully adherent, partially adherent or fully non-adherent with their cardiovascular drug regimen based on whether they adhered with all, part or none of their drugs. AET discontinuation was defined as a 90-day gap in AET availability. Time to AET discontinuation according to levels of cardiovascular drug adherence was estimated using cumulative incidence curves, accounting for the competing risks of death and cancer recurrence. Multivariate cause-specific Cox regressions and Fine-and-Gray regressions were used to assess the relative hazards of AET discontinuation.

RESULTS

In total, 32,075 women fit the inclusion criteria. Women who were fully adherent with their cardiovascular drugs had the lowest cumulative incidence of AET discontinuation at any point over the 5-year follow-up period. At 5 years, 40.2% of fully non-adherent women had discontinued AET compared with 33.5% of partially adherent women and 28.8% of fully adherent women. Both partial adherence and full non-adherence with cardiovascular drugs were predictors of AET discontinuation in the two models (cause-specific hazard ratios 1.16 [95% CI 1.10-1.22] and 1.49 [95% CI 1.39-1.58]; subdistribution hazard ratios 1.15 [95% CI 1.10-1.21] and 1.47 [95% CI 1.38-1.57]).

CONCLUSION

Clinicians should be aware that patients who do not adhere with their entire cardiovascular drug regimen are also more likely to discontinue AET. This stresses the importance of integrated care, as suboptimal adherence with both treatment components poses a threat to achieving ideal patient outcomes.

The Impact of Non-Adherence to Antihypertensive Drug Therapy

Medication non-adherence is a major healthcare barrier, especially among diseases that are largely asymptomatic, such as hypertension. The impact of poor medication adherence ranges from patient-specific adverse health outcomes to broader strains on health care system resources. The Centers for Disease Control (CDC) Wide-ranging Online Data for Epidemiologic Research (WONDER) database was used to retrieve Centers for Medicare and Medicaid Services' data pertaining to blood pressure (BP) medication adherence, socio-economic variables, and cardiovascular (CV) outcomes across the United States. Multivariable linear regression models were used to estimate the change in total CV deaths as a function of non-adherence to BP medications. For every percent increase in the non-adherence rate, the total number of CV deaths increased by 7.13 deaths per 100,000 adults (95% CI: 6.34-7.92), even after controlling for the percentage of residents with access to insurance, the percentage of residents who were eligible for Medicaid, the percentage of residents without a college education, median home value, income inequality, and the poverty rate (p < 0.001). There is a significant association between non-adherence to BP medications and total CV deaths. Even a one percent increase in the adherence rate in the United States could result in tens of thousands of preventable CV deaths. Based on recently published CDC data, this could also have a tremendous impact on health care costs. This provides compelling evidence for increased efforts to improve adherence.

Online-Mediated HIV Pre-exposure Prophylaxis Care and Reduced Monitoring Frequency for Men Who Have Sex With Men: Protocol for a Randomized Controlled Noninferiority Trial (EZI-PrEP Study)

BACKGROUND

Daily and event-driven HIV pre-exposure prophylaxis (PrEP) with oral tenofovir-emtricitabine is highly effective to prevent HIV in men who have sex with men (MSM). PrEP care generally consists of in-clinic monitoring every 3 months that includes PrEP dispensing, counseling, and screening for HIV and sexually transmitted infections (STIs). However, the optimal frequency for monitoring remains undetermined. Attending a clinic every 3 months for monitoring may be a barrier for PrEP. Online-mediated PrEP care and reduced frequency of monitoring may lower this barrier.

OBJECTIVE

The primary objective of this study is to establish the noninferiority of online PrEP care (vs in-clinic care) and monitoring every 6 months (vs every 3 months). The secondary objectives are to (1) examine differences between PrEP care modalities regarding incidences of STIs, HIV infection, and hepatitis C virus infection; retention in PrEP care; intracellular tenofovir-diphosphate concentration; and satisfaction, usability, and acceptability of PrEP care modalities; and (2) evaluate associations of these study outcomes with sociodemographic, behavioral, and psychological characteristics.

METHODS

This study is a 2×2 factorial, 4-arm, open-label, multi-center, randomized, controlled, noninferiority trial. The 4 arms are (1) in-clinic monitoring every 3 months, (2) in-clinic monitoring every 6 months, (3) online monitoring every 3 months, and (4) online monitoring every 6 months. The primary outcome is a condomless anal sex act with a casual partner not covered or insufficiently covered by PrEP (ie, "unprotected act") as a proxy for HIV infection risk. Eligible individuals are MSM, and transgender and gender diverse people aged ≥18 years who are eligible for PrEP care at 1 of 4 participating sexual health centers in the Netherlands. The required sample size is 442 participants, and the planned observation time is 24 months. All study participants will receive access to a smartphone app, which contains a diary. Participants are requested to complete the diary on a daily basis during the first 18 months of participation. Participants will complete questionnaires at baseline and 6, 12, 18, and 24 months. Dried blood spots will be collected at 6 and 12 months for assessment of intracellular tenofovir-diphosphate concentration. Incidence rates of unprotected acts will be compared between the online and in-clinic arms, and between the 6-month and 3-month arms. Noninferiority will be concluded if the upper limit of the 2-sided 97.5% CI of the incidence rate ratio is <1.8.

RESULTS

The results of the main analysis are expected in 2024.

CONCLUSIONS

This trial will demonstrate whether online PrEP care and monitoring every 6 months is noninferior to standard PrEP care in terms of PrEP adherence. If noninferiority is established, these modalities may lower barriers for initiating and continuing PrEP use and potentially reduce the systemic burden for PrEP providers.

Psychosocial characteristics are associated with adherence to dietary, drugs and physical activity recommendations amongst cardiovascular disease patients in Lebanon

Cardiovascular diseases are increasing at an alarming rate worldwide, reaching epidemic proportions in countries of the Eastern Mediterranean Region, including Lebanon. Despite the growing number of patients suffering from cardiovascular diseases in Lebanon, there is scarce data on whether cardiac patients adhere to therapeutic dietary guidelines, drug prescriptions, and physical activity recommendations and whether such adherence differs according to sociodemographic, lifestyle, or psychosocial characteristics. A cross-sectional study was conducted among 367 Lebanese adult cardiovascular disease patients admitted for hospitalization at various hospital sites in Lebanon. Electronic medical records and a multi-component questionnaire were used to collect information on patients' characteristics. Dietary assessment was performed using a culture-specific validated food frequency questionnaire, and physical activity levels were assessed using the international physical activity questionnaire (IPAQ). Mental well-being was assessed based on the validated five-item well-being index (WHO-5), and drug adherence was evaluated using the Morisky medication adherence scale (MMAS-8). The majority of the patients were males (67.8%), overweight or obese (74%), smokers (62.1%), and unemployed or retired (54.5%). Almost 35% of the patients were lonely, and nearly one fourth were at a high risk of poor mental health. Approximately 43%, 70%, and 52% of the patients were found to have poor adherence to diet, drug, and physical activity recommendations, respectively. A lower sense of mental well-being was a significant predictor of low dietary and drug adherence. Surprisingly, overweight and obesity were associated with higher odds of dietary adherence. Male gender was positively associated with physical activity while loneliness was inversely associated with physical activity. This study showed that adherence to diet, drug, and physical activity recommendations was low in this patient population and identified several non-clinical characteristics that may affect adherence. These findings highlighted the need for considering patients' psychosocial characteristics in the treatment of patients with cardiovascular diseases.

Gender-Related Factors in Medication Adherence for Metabolic and Cardiovascular Health

This review explores the impact of gender on medication adherence in the context of metabolic and cardiovascular diseases. Optimal adherence to medication is crucial for achieving treatment goals and preventing adverse outcomes in chronic diseases. The review examines specific conditions such as type 2 diabetes, hypercholesterolemia, arterial hypertension, cardiovascular diseases, and heart failure. In type 2 diabetes, female sex, younger age, new drug prescription, non-white ethnicity, low education level, and low income were identified as predictors of non-adherence. Depressive disorders were also found to influence adherence. In hypercholesterolemia, women exhibited poorer adherence to statin therapy compared to men, with statin-related side effects and patient perception being significant factors. Adherence to anti-hypertensive therapy showed conflicting results, with studies reporting both higher and lower adherence in women. Limited evidence suggests that women may have poorer adherence after acute myocardial infarction and stroke. Regarding heart failure, adherence studies have shown inconsistent findings. The reasons for gender differences in medication adherence are multifactorial and include sociodemographic, disease-related, treatment-related, and psychological factors. This review emphasizes the need for further research to better understand these differences and develop gender-customized interventions that can improve medication adherence and reduce the burden of metabolic and cardiovascular diseases.

What is the impact of one's chronic illness on his or her spouse's future chronic illness: a community-based prospective cohort study

BACKGROUND

Integrating a joint approach to chronic disease management within the context of a couple has immense potential as a valuable strategy for both prevention and treatment. Although spousal concordance has been reported in specific chronic illnesses, the impact they cumulatively exert on a spouse in a longitudinal setting has not been investigated. We aimed to determine whether one's cumulative illness burden has a longitudinal impact on that of their spouse.

METHODS

Data was acquired from a community-based prospective cohort that included Koreans aged 60 years and over, randomly sampled from 13 districts nationwide. Data from the baseline assessment (conducted from November 2010 to October 2012) up to the 8-year follow-up assessment was analyzed from October 2021 to November 2022. At the last assessment, partners of the index participants were invited, and we included 814 couples in the analysis after excluding 51 with incomplete variables. Chronic illness burden of the participants was measured by the Cumulative Illness Rating Scale (CIRS). Multivariable linear regression and causal mediation analysis were used to examine the longitudinal effects of index chronic illness burden at baseline and its change during follow-up on future index and spouse CIRS scores.

RESULTS

Index participants were divided based on baseline CIRS scores (CIRS < 6 points, n = 555, mean [SD] age 66.3 [4.79] years, 43% women; CIRS ≥ 6 points, n = 259, mean [SD] age 67.7 [4.76] years, 36% women). The baseline index CIRS scores and change in index CIRS scores during follow-up were associated with the spouse CIRS scores (β = 0.154 [SE: 0.039], p < 0.001 for baseline index CIRS; β = 0.126 [SE: 0.041], p = 0.002 for change in index CIRS) at the 8-year follow-up assessment. Subgroup analysis found similar results only in the high CIRS group. The baseline index CIRS scores and change in index CIRS scores during follow-up had both direct and indirect effects on the spouse CIRS scores at the 8-year follow-up assessment.

CONCLUSIONS

The severity and course of one's chronic illnesses had a significant effect on their spouse's future chronic illness particularly when it was severe. Management strategies for chronic diseases that are centered on couples may be more effective.

Pharmacologic Stewardship in a Rural Community Pharmacy

BACKGROUND

Pharmacotherapy is an essential part of patient care. In order to achieve optimal health outcomes, safe and effective prescribing and administering of medications is crucial, especially since the process of pharmacotherapy can cause serious problems, mainly adverse events and/or interactions, that often pass undetected.

OBJECTIVE(S)

To investigate the feasibility of using community pharmacies as checkpoints to detect errors and failures in prescribing, as well as patients' compliance with pharmacotherapy. To this end, analysis and recording of the prescribing process was carried out and error-prone points were identified.

METHODS

Patients and caregivers filling prescriptions during the first 4 weeks of November 2017 and February 2018 answered questions in order to evaluate their attendance of regular checkups and their compliance with prescribing instructions. All prescriptions filled at the pharmacy were examined for detection of prescription errors and drug-drug interactions. Statistical analyses, including calculations of the correlation coefficient phi (φ), chi-square, and confidence intervals, were carried out. Detected errors and failures were evaluated by application of the Health Failure Mode Effect Analysis (HFMEA) quality tool.

RESULTS

A significant number of patients (16.7%) failed to regularly attend checkups regarding known health problems (95% CI: 10.6-22.7%), a corresponding percentage (16%, 95% CI: 10.1-21.9%) did not comply with prescribed pharmacotherapy, and a significant proportion of patients self-medicated regularly (32%, 95% CI: 24.5-39.5%). A total of 8.6% of prescriptions included medication combinations with a potential for severe drug-drug interactions (95% CI: 7.1-10.2%) while 58.7% of the prescriptions included combinations that could lead to moderate ones (95% CI: 56.1-61.4). The HFMEA indicated that all problems recorded required immediate interventions, except for prescribing errors.

CONCLUSIONS

Community pharmacies can be potential checkpoints for the detection and evaluation of prescribing errors and pharmacotherapy failures.

Benefits of the Polypill on Medication Adherence in the Primary and Secondary Prevention of Cardiovascular Disease: A Systematic Review

Background

Higher medication adherence reduces the risk of new cardiovascular events. However, there are individual and health system barriers that lead to lower adherence. The polypill has demonstrated benefits in cardiovascular morbidity and mortality mainly driven by an increase in adherence. We aim to evaluate the impact of the polypill on adherence to cardiovascular medication, its efficacy and safety in cardiovascular disease (CVD) prevention.

Methods

A systematic review following PRISMA guidelines was conducted. Databases were searched from January 2003 to December 2022. We included randomized, pragmatic, or real-world clinical trials and observational studies. The primary outcome was medication adherence, secondary outcomes were efficacy in cardiovascular disease in primary and secondary prevention and safety.

Results

From the 490 publications screened, 13 met the inclusion criteria and were incorporated into a comparative table Of those included, 70% were randomized controlled trials (RCTs) and 53.8% focused on secondary prevention. Most of the studies received a high and moderate quality rating. Self-report, pill counting and, the Morisky scale were the most frequent methods to evaluate adherence (84.6%). Compared with standard medication, the polypill improved overall medication adherence by 13%, with percentages ranging from 7.6% to 34.9%. Moreover, a potential benefit was also observed in reducing Major Adverse Cardiovascular Events (MACE), particularly in secondary prevention studies, with hazard ratios ranged between 0.43 to 0.76. Compared to standard care, the profile of side effects was similar.

Conclusion

The polypill is an effective, safe, and practical strategy to improve adherence in people at risk of CVD. Although there is a demonstrated benefit in reducing MACE, predominantly in secondary prevention, there are still gaps in its efficacy in primary prevention and reducing total mortality. Therefore, the importance of obtaining long-term results of the polypill effect and how this strategy can be implemented in real practice.

Guideline-directed medical therapy for HFrEF: sequencing strategies and barriers for life-saving drug therapy

Multiple landmark trials have helped to advance the treatment of heart failure with reduced ejection fraction (HFrEF) significantly over the past decade. These trials have led to the introduction of four main drug classes into the 2021 ESC guideline, namely angiotensin-receptor neprilysin inhibitors/angiotensin-converting-enzyme inhibitors, beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter-2 inhibitors. The life-saving effect of these therapies has been shown to be additive and becomes apparent within weeks, which is why maximally tolerated or target doses of all drug classes should be strived for as quickly as possible. Recent evidence, such as the STRONG-HF trial, demonstrated that rapid drug implementation and up-titration is superior to the traditional and more gradual step-by-step approach where valuable time is lost to up-titration. Accordingly, multiple rapid drug implementation and sequencing strategies have been proposed to significantly reduce the time needed for the titration process. Such strategies are urgently needed since previous large-scale registries have shown that guideline-directed medical therapy (GDMT) implementation is a challenge. This challenge is reflected by generally low adherence rates, which can be attributed to factors considering the patient, health care system, and local hospital/health care provider. This review of the four medication classes used to treat HFrEF seeks to present a thorough overview of the data supporting current GDMT, discuss the obstacles to GDMT implementation and up-titration, and identify multiple sequencing strategies that could improve GDMT adherence. Sequencing strategies for GDMT implementation. GDMT: guideline-directed medical therapy; ACEi: angiotensin-converting enzyme inhibitor; ARB: Angiotensin II receptor blocker; ARNi: angiotensin receptor-neprilysin inhibitor; BB: beta-blocker; MRA: mineralocorticoid receptor antagonist; SGLT2i: sodium-glucose co-transporter 2 inhibitor.

[Cardiovascular pharmacotherapy in old age]

Cardiovascular diseases are the most frequent cause of disability and death. Evidence-based pharmacotherapy is the basis for successful treatment of common diseases, such as hypertension, heart failure, coronary artery disease, and atrial fibrillation. The proportion of older people with several diseases (multimorbidity) who need five or more drugs daily (polypharmacy) is steadily increasing. Evidence on the efficacy and safety of drugs in these patients is, however, limited because they are often excluded or underrepresented in clinical trials. In addition, clinical guidelines mostly focus on single diseases and only occasionally deal with the challenges in the pharmacotherapy of older multimorbid patients with polypharmacy. This article describes the options and special features of pharmacotherapy for hypertension, chronic heart failure and dyslipidemia, as well as antithrombotic treatment in (very) old people.

Results from the "Me & My Heart" (eMocial) Study: a Randomized Evaluation of a New Smartphone-Based Support Tool to Increase Therapy Adherence of Patients with Acute Coronary Syndrome

PURPOSE

This study evaluated whether patient support, administered via an electronic device-based app, increased adherence to treatment and lifestyle changes in patients with acute coronary syndrome (ACS) treated with ticagrelor in routine clinical practice.

METHODS

Patients (aged ≥ 18 years) with diagnosed ACS treated with ticagrelor co-administered with low-dose acetylsalicylic acid were randomized into an active group (with support tool app for medication intake reminders and motivational messages) and a control group (without support tool app), and observed for 48 weeks (ClinicalTrials.gov Identifier: NCT02615704). Patients were asked to complete the 36-item Short-Form Health Survey (SF-36) and Lifestyle Changes Questionnaire (LSQ), and were assessed for blood pressure and body mass index (BMI) at baseline (visit 1) and at the end of the study (visit 2). Medication adherence was measured using the Brilique Adherence Questionnaire (BAQ).

RESULTS

Patients (N = 676) were randomized to an active (n = 342) or a control (n = 334) group. BAQ data were available for 174 patients in the active group and 174 patients in the control group. Over the 48-week period, mean (standard deviation) adherence for the active and control groups was 96.4% (13.2%) and 91.5% (23.1%), respectively (effect of app intervention, p < 0.05). There were no significant differences in blood pressure and BMI between visits. General improvements in SF-36 and LSQ scores were observed for both groups.

CONCLUSION

The patient support tool app was associated with significant improvements in patient-reported treatment adherence compared with a data collection app alone in patients prescribed ticagrelor for ACS.
