A practice-based trial of motivational interviewing and adherence in hypertensive African Americans

Motivational interviewing intervention for the management of hypertension: a meta-analysis

Background

Improving medication compliance and self-efficacy in hypertensive patients is of significant importance for their prognosis. This meta-analysis aimed to assess the role of motivational interviewing in reducing systolic and diastolic blood pressure, self-efficacy, quality of life and medication adherence in hypertensive patients.

Methods

Two authors searched PubMed, Cochrane Library, Clinicaltrials, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database, Weipu and Wanfang Database up to May 28, 2024 for randomized controlled trials (RCTs) evaluating the role of motivational interviewing on hypertensive patients. The search was restricted to articles published in English and Chinese languages. RevMan 5.4 software was used for meta-analysis.

Results

A total of 16 RCTs were included. The meta-analysis findings demonstrate that motivational interviewing could reduce both systolic pressure [MD = -3.26, 95% CI (-5.16, -1.36), P < 0.001] and diastolic blood pressure [MD = -1.78, 95% CI (-3.48, -0.08), P < 0.001] levels in hypertensive patients, while simultaneously enhancing their self-efficacy [MD = 2.92, 95% CI (1.84, 4.00), P = 0.001], quality of life [MD = 6.99, 95% CI (3.25, 10.74), P = 0.003], and medication compliance [OR = 4.30, 95% CI (1.53, 12.10), P = 0.003]. No significant publication bias across the synthesized outcomes were found by Egger regression analyses (all P > 0.05).

Conclusions

Motivational interviewing has been shown to effectively reduce blood pressure in the short term among individuals with hypertension, while simultaneously enhancing their self-efficacy, quality of life, and adherence to medication regimens.

Comparative Different Interventions to Improve Medication Adherence in Patients with Hypertension: A Network Meta-analysis

BACKGROUND

Hypertension has become a major public problem. One of every 4 adults has hypertension. Medications are critical in controlling blood pressure, but patient medication adherence is low. Therefore, it is very crucial to promote medication adherence. However, the complexity and variety of interventions cause clinical decision-making difficulties for health managers and patients.

OBJECTIVE

The aim of this study was to compare the effectiveness of different interventions to improve medication adherence in patients with hypertension.

METHODS

We searched PubMed, Cochrane Library, Web of Science, EMBASE, Wan Fang, China National Knowledge Infrastructure, China Science and Technology Journal Database, and China Biology Medicine disc databases for eligible studies. Medication adherence rate and medication adherence difference were assessed as outcomes. Sensitivity analysis and inconsistency detection were performed to evaluate whether the exclusion of high-risk studies affected the validity. The risk of bias was assessed using the risk of bias table in Review Manager 5.4. The surface under the cumulative ranking curve was used to estimate the rankings among different interventions.

RESULTS

Twenty-seven randomized controlled trials were included, and the interventions involved were categorized into 8 different categories. The network meta-analysis showed that the health intervention was the best to promote medication compliance in patients with hypertension.

CONCLUSIONS

Health intervention is recommended to improve medication adherence in patients with hypertension.

CLINICAL IMPLICATIONS

Health managers are recommended to provide health intervention to patients with hypertension to improve their medication adherence. This approach reduces morbidity, mortality, and healthcare costs for patients with cardiovascular disease.

The Role of Primary Care in Achieving Life's Essential 8: A Scientific Statement From the American Heart Association

To reduce morbidity and mortality rates of cardiovascular disease, an urgent need exists to improve cardiovascular health among US adults. In 2022, the American Heart Association issued Life's Essential 8, which identifies and defines 8 health behaviors and factors that, when optimized through a combination of primary prevention, risk factor management, and effective treatments, can promote ideal cardiovascular health. Because of its central role in patient care across the life span, primary care is in a strategic position to promote Life's Essential 8 and improve cardiovascular health in the United States. High-quality primary care is person-centered, team-based, community-aligned, and designed to provide affordable optimized health care. The purpose of this scientific statement from the American Heart Association is to provide evidence-based guidance on how primary care, as a field and practice, can support patients in implementing Life's Essential 8. The scientific statement aims to describe the role and functions of primary care, provide evidence for how primary care can be leveraged to promote Life's Essential 8, examine the role of primary care in providing access to care and mitigating disparities in cardiovascular health, review challenges in primary care, and propose solutions to address challenges in achieving Life's Essential 8.

Interventional Glaucoma: Improving the Patient-Provider Educational Exchange

Glaucoma treatment is beginning to undergo an evolution, moving away from topical medication-based therapies toward more proactive minimally invasive interventions. This shift towards an "interventional glaucoma" treatment paradigm has been shown to benefit patients, providers, and society. A key component of effectively implementing this approach is education about the importance of glaucoma diagnosis and treatment, as well as the various treatment modalities available. Such education is relevant not only for patient but also patients' support networks, ophthalmologists, optometrists, third-party payers, and policy-makers. Education can occur both within and outside the clinical setting. The present article provides an overview of the diverse educational methods available for glaucoma patients, including those based on patient-provider interactions and those based on internet and printed material. Examples of the former could include general and specific verbal instruction, motivational interviewing, or community-based educational workshops, while examples of the latter could include office-based movies or printed materials, virtual reality headset educational videos, artificial intelligence-assisted education, or self-directed internet videos and articles. By empowering patients with knowledge and an up-to-date awareness of treatment options, effective education can be a valuable part of making an interventional glaucoma treatment paradigm possible.

Role of Health Care Professionals in the Success of Blood Pressure Control Interventions in Patients With Hypertension: A Meta-Analysis

BACKGROUND

Globally, only 13.8% of patients with hypertension have their blood pressure (BP) controlled. Trials testing interventions to overcome barriers to BP control have produced mixed results. Type of health care professional delivering the intervention may play an important role in intervention success. The goal of this meta-analysis is to determine which health care professionals are most effective at delivering BP reduction interventions.

METHODS

We searched Medline and Embase (until December 2023) for randomized controlled trials of interventions targeting barriers to hypertension control reporting who led intervention delivery. One hundred articles worldwide with 116 comparisons and 90 474 participants with hypertension were included. Trials were grouped by health care professional, and the effects of the intervention on systolic and diastolic BP were combined using random effects models and generalized estimating equations.

RESULTS

Pharmacist-led interventions , community health worker-led interventions, and health educator-led interventions resulted in the greatest systolic BP reductions of -7.3 (95% CI, -9.1 to -5.6), -7.1 (95% CI, -10.8 to -3.4), and -5.2 (95% CI, -7.8 to -2.6) mm Hg, respectively. Interventions led by multiple health care professionals, nurses, and physicians also resulted in significant systolic BP reductions of -4.2 (95% CI, -6.1 to -2.4), -3.0 (95% CI, -4.2 to -1.9), and -2.4 (95% CI, -3.4 to -1.5) mm Hg, respectively. Similarly, the greatest diastolic BP reductions were -3.9 (95% CI, -5.2 to -2.5) mm Hg for pharmacist-led and -3.7 (95% CI, -6.6 to -0.8) mm Hg for community health worker-led interventions. In pairwise comparisons, pharmacist were significantly more effective than multiple health care professionals, nurses, and physicians at delivering interventions.

CONCLUSIONS

Pharmacists and community health workers are most effective at leading BP intervention implementation and should be prioritized in future hypertension control 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.

Trajectories of adherence to ACEI/ARB medications following a motivational interviewing intervention among Medicare Advantage beneficiaries in Texas

OBJECTIVES

To assess the impact of student telephone motivational interviewing intervention on angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (ACEI/ARBs) adherence trajectories and identify predictors of each trajectory.

METHODS

The intervention group included continuously enrolled Medicare Advantage Plan patients non-adherent to ACEI/ARBs vs the control group (1:2 ratio). The intervention was tailored by pre-intervention trajectories and included an initial and five follow-up calls. Adherence was measured 6 months after initial calls using the proportion of days covered (PDC). Monthly PDCs were integrated into a group-based trajectory model and categorized patients into 4-groups. A multinomial logistic regression model was used to evaluate trajectory predictors.

RESULTS

The study comprised 240 intervention patients and 480 controls with four trajectories: adherent trajectory 44.2%, gradual improvement in adherence 13.4%, slow decline in adherence 24.1%, and discontinuation 18.3%. Patients with the intervention were less likely to experience a slow decline in adherence than controls (OR: 0.627 [0.401-0.981]). Patients with specialty prescribers' visits, ≥ 1 previous hospitalization, rapid decline in adherence as pre-intervention trajectory, and higher CMS risk score were associated with discontinuation trajectory.

CONCLUSION

Intervention patients vs controls had a lower likelihood of following a slow decline in adherence pattern.

PRACTICE IMPLICATIONS

This study underscores the importance of individualized interventions and the association between past adherence patterns and post-intervention trajectories.

Systematic review of motivational interventions to improve adherence to medication in patients with hypertension and meta-analysis

INTRODUCTION

Antihypertensive medication non-adherence is an important cause of poor control in hypertension. The role of motivational interventions to increase antihypertensive medication adherence remains unclear.

OBJECTIVE

To systematically review RCTs of motivational interventions for improving medication adherence in hypertension.

METHODS

EMBASE and Pubmed were searched from inception to February 2019 for RCTs of motivational interventions for improving medication adherence in hypertension vs. usual care.

INCLUSION CRITERIA

RCTs with motivational intervention to improve medication adherence in adults with hypertension. A blinded review was conducted by 2 reviewers. Disagreements were resolved by consensus/a third reviewer. Data extraction and quality appraisal was performed using the risk of bias tool from cochrane collaboration. The meta-analyses of blood pressure control used random-effects models to report mean difference and 95% CIs. Primary outcome was medication adherence and second outcome was blood pressure control.

RESULTS

The search methodology yielded 10 studies comprising 1171 participants. Medication adherence improved significantly in 5 studies. We could not perform pool analysis for this outcome due to different measurements of medication adherence. Seven trials reported significant results regarding blood pressure control. On pooled analysis, motivational interventions were not significantly associated with a systolic blood pressure (mean difference, -0.06; 95% CI, -0.05 to 0.18; p=0.63; I2=0.0%) or diastolic blood pressure (mean difference, -0.11; 95% CI, -0.10 to 0.31; p=0.28; I2=23.8%) decrease or blood pressure control.

CONCLUSIONS

Motivational interventions seem to significantly improve medication adherence but not significantly blood pressure control in hypertension, although evidence is still being based on few studies, with unclear risk of bias.

The effects of motivational interviewing on hypertension management: A systematic review and meta-analysis

OBJECTIVE

This systematic review aimed to examine the effects of motivational interviewing-based interventions on hypertension management.

METHODS

Six databases were searched from inception to 25 July, 2022 for randomized controlled trials involving adults diagnosed with hypertension and including motivational interviewing in the treatment interventions.

RESULTS

In total, 11 studies with 2121 participants were included. Compared with no or minimal additional intervention, motivational interviewing-based intervention showed greater reduction in systolic blood pressure (MD: -6.56, 95 % CI: -10.51, -2.62, P = 0.001) and diastolic blood pressure (MD: -3.75, 95 % CI: -4.92, -2.58, P < 0.001). Compared with the lower intensity intervention, motivational interviewing-based intervention produced statistically significant effect on reducing systolic blood pressure (MD: -2.72, 95 % CI: -5.34, -0.10, P = 0.040); while there was no significant effect on reducing diastolic blood pressure (MD: -0.47, 95 % CI: -2.21, 1.28, P = 0.600). Four out of six studies demonstrated medication adherence significantly improved following motivational interviewing-based intervention. Two studies included self-efficacy and quality of life, and inconsistent findings were observed.

CONCLUSION

Motivational interviewing could be effective in improving blood pressure control among patients with hypertension. Future studies with more rigorous study designs should be conducted to confirm the effects of motivational interviewing on medication adherence and psychological well-being.

PRACTICE IMPLICATIONS

Motivational interviewing could be applied as a promising intervention strategy among patients with hypertension.

Utilization obstacles to hypertension services provided at comprehensive health centers: a content analysis study

INTRODUCTION

Hypertensive patients' failure to refer to health centers for the management of their disease is the most fundamental public health challenge in most societies. The aim of this study was to identify the utilization obstacles to hypertension services provided at comprehensive health centers (CHCs) from the perspective of patients and the staff of health centers.

METHODS

This was a qualitative study using conventional content analysis which was conducted in 2022. Participants included 15 hypertensive patients referring to CHCs and 10 staff (including personnel of CHCs and expert staff) of Ahvaz Jundishapur University of Medical Sciences, Ahvaz, southwest of Iran. Data were collected using semi-structured interviews. Interviews were analyzed using content analysis method, and coding was done manually.

RESULTS

In total, 15 codes and 8 categories were extracted from the interviews which were organized in two main themes of "individual problems" and "systemic problems". More particularly, the main theme of "individual problems" involved attitudinal obstacles, occupational obstacles, and economic obstacles. The main theme of "systemic problems" included educational obstacles, motivational obstacles, procedural obstacles, structural obstacles, and managerial obstacles.

CONCLUSION

In order to address individual problems associated with the patients' failure to refer to CHCs, we need to take appropriate measures. These include using motivational interviewing techniques and utilizing the effective activity of healthcare liaisons and volunteers in CHCs to increase patients' awareness and change their negative attitudes and misconceptions. To solve systemic problems, it is imperative that effective training courses be held for health center staff.

Motivational interviewing to support medication adherence in adults with chronic conditions: Systematic review of randomized controlled trials

OBJECTIVES

To systematically review published randomized controlled trials (RCTs) assessing the efficacy of MI to support medication adherence in adults with chronic conditions.

METHODS

A systematic review (PROSPERO-CRD42020025374) was performed by searching in Pubmed/MEDLINE, PsycINFO, The Cochrane Library and Web of Science. Studies were included for the following: RCTs assessing the impact of MI on medication adherence among adults with chronic diseases. Two reviewers conducted independent screening of records and full-text articles published until July 2020. Quality was assessed with the Risk of Bias 2 tool for RCTs.

RESULTS

From 1262 records identified, 54 RCTs were included. The MI interventions were delivered alone or in combination with other interventions, and varied in mode of delivery (e.g. face-to-face, phone), exposure level (duration, number of sessions), and provider characteristics (profession, training). Most interventions were developed in infectious diseases (n = 16), cardiology (n = 14), psychiatry (n = 8), and endocrinology (n = 7). Medication adherence showed significant improvement in 23 RCTs, and other clinical outcomes were improved in 19 RCTs (e.g. risky behaviors, disease symptoms).

CONCLUSIONS

MI is an approach to medication adherence support with an increasing evidence base in several clinical domains and further potential for adaptation to different settings.

PRACTICE IMPLICATIONS

In further studies, particular attention should focus on methodological issues such as the populations of patients to include - patients with suboptimal adherence, the evaluation of fidelity to the MI spirit and components, and a sound measurement of medication adherence and clinical outcomes.

Study design of BETTER-BP: Behavioral economics trial to enhance regulation of blood pressure

Background

Nonadherence to antihypertensive medications remains a persistent problem that leads to preventable morbidity and mortality. Behavioral economic strategies represent a novel way to improve antihypertensive medication adherence, but remain largely untested especially in vulnerable populations which stand to benefit the most. The Behavioral Economics Trial To Enhance Regulation of Blood Pressure (BETTER-BP) was designed in this context, to test whether a digitally-enabled incentive lottery improves antihypertensive adherence and reduces systolic blood pressure (SBP).

Design

BETTER-BP is a pragmatic randomized trial conducted within 3 safety-net clinics in New York City: Bellevue Hospital Center, Gouveneur Hospital Center, and NYU Family Health Centers - Park Slope. The trial will randomize 435 patients with poorly controlled hypertension and poor adherence (<80% days adherent) in a 2:1 ratio (intervention:control) to receive either an incentive lottery versus passive monitoring. The incentive lottery is delivered via short messaging service (SMS) text messages that are delivered based on (1) antihypertensive adherence tracked via a wireless electronic monitoring device, paired with (2) a probability of lottery winning with variable incentives and a regret component for nonadherence. The study intervention lasts for 6 months, and ambulatory systolic blood pressure (SBP) will be measured at both 6 and 12 months to evaluate immediate and durable lottery effects.

Conclusions

BETTER-BP will generate knowledge about whether an incentive lottery is effective in vulnerable populations to improve antihypertensive medication adherence. If successful, this could lead to the implementation of this novel strategy on a larger scale to improve outcomes.

Effects of health coaching on menopausal symptoms in postmenopausal and perimenopausal women

OBJECTIVE

This study aimed to determine the effects of health coaching on reducing menopausal symptoms in postmenopausal and perimenopausal women.

METHODS

This randomized controlled study was performed on 94 postmenopausal and perimenopausal women aged 45 to 55 years. The participants were randomly divided into intervention and control groups. In the intervention group, health coaching was performed in five coaching sessions biweekly (30-45 minutes each) by a midwifery coach. The primary outcome of this study was the menopausal score based on the modified Kupperman Index at 4 months after randomization. Depression (based on Zung's Self-Rating Depression Scale), physical activity (based on the International Physical Activity Questionnaire), quality of life (based on the 12-Item Short-Form Survey), smoking, alcohol intake, and anthropometric indices were also evaluated as secondary outcomes.

RESULTS

There was a significant mean difference between the coaching and control groups in terms of change in the scores of menopausal symptoms from baseline (T0) to 4 months after the intervention (T1; -12.51; 95% confidence interval [CI], -10.59 to -14.42; P = 0.001). Moreover, a significant mean difference was observed between the two groups in terms of change in depression symptoms from T0 to T1 (-5.72; 95% CI, -7.61 to -3.83; P < 0.001) and in terms of quality of life (4.13; 95% CI, 2.95 to 5.31; P < 0.001). Health coaching, however, had no effects on the physical activity of the participants.

CONCLUSION

Based on the present results, the coaching intervention is a suitable method to improve quality of life by reducing weight, waist circumference, body mass index, depression, and menopausal symptoms in postmenopausal and perimenopausal women. It can have important effects on the development of health promotion programs to reduce menopausal symptoms in menopause clinics.

A small cluster randomised clinical trial to improve health outcomes among Argentine patients disengaged from HIV care

Background

Patients disengaged from HIV care, e.g., missed medication pick-ups, not attending physician visits, account for ≥70% of new HIV infections. Re-engaging and sustaining engagement is essential to controlling the HIV pandemic. This study tested a physician-delivered evidence-based intervention, Motivational Interviewing (MI), to improve health outcomes, adherence to antiretroviral therapy (ART), HIV virologic suppression, CD4+ count, retention in HIV care, and self-efficacy among patients disengaged from care in Argentina.

Methods

Regional clinics (n = 6) were randomised to condition, MI Intervention or Enhanced Standard of Care (ESOC), and recruited N = 360 patients disengaged from HIV care. ART adherence, HIV RNA viral load, CD4+ count retention, and self-efficacy were assessed at baseline, 6, 12, 18, and 24-months. Indirect effects from condition to main outcomes were examined using patient-provider relationship as a mediator. The study was a cluster-randomised clinical trial entitled Conexiones y Opciones Positivas en la Argentina 2 (COPA2) and was registered at clinicaltrials.gov, NCT02846350.

Findings

Participants were an average age of 39·15 (SD = 10·96), 51% were women; intervention participants were older (p = ·019), and more ESOC participants were women (60% vs. 42%, p = 0·001). Using mixed models, the intervention had no effect on ART adherence over time by condition on HIV RNA viral load, CD4+ count retention, or self-efficacy. However, analysing mediated paths, there was an indirect effect of condition on ART adherence (B = 0·188, p = 0·009), HIV viral load (B = -0·095, P = 0·027), and self-efficacy (B = 0·063, P = 0·001), suggesting the intervention was associated with improved patient-provider relationships, which was in turn associated with increased ART adherence, lower HIV viral load, and higher self-efficacy.

Interpretation

These findings suggest that physician-delivered MI may enhance the patient-provider relationship, self-efficacy, and ART adherence, and reduced HIV viral load in patients disengaged from HIV care. However, these findings are preliminary due to the small number of clusters randomised, and replication is warranted.

Using mHealth to improve adherence and reduce blood pressure in individuals with hypertension and bipolar disorder (iTAB-CV): study protocol for a 2-stage randomized clinical trial

BACKGROUND

Cardiovascular disease in individuals with mental health conditions such as bipolar disorder is highly prevalent and often poorly managed. Individuals with bipolar disorder face significant medication adherence barriers, especially when they are prescribed multiple medications for other health conditions including hypertension. Poor adherence puts them at a disproportionate risk for poor health outcomes. As such, there is a need for effective interventions to improve hypertension medication adherence, particularly in patients that struggle with adherence due to mental health comorbidity.

METHODS

This 5-year project uses a 2-stage randomized controlled trial design to evaluate a brief, practical adherence intervention delivered via interactive text messaging (iTAB-CV) along with self-monitoring of medication taking, mood, and home blood pressure (N = 100) compared to self-monitoring alone (N = 100). Prior to randomization, all participants will view an educational video that emphasizes the importance of medication for the treatment of hypertension and bipolar disorder. Those randomized to the texting intervention will receive daily text messages with predetermined content to address 11 salient domains as well as targeted customized messages for 2 months. This group will then be re-randomized to receive either a high (gradual taper from daily to weekly texts) or low booster (weekly texts) phase for an additional 2 months. All participants will be monitored for 52 weeks. The primary outcomes are systolic blood pressure and adherence to antihypertensive medication as determined by a self-reported questionnaire and validated with an automated pill-monitoring device. Secondary outcomes include adherence to bipolar disorder medications, psychiatric symptoms, health status, self-efficacy for medication-taking behavior, illness beliefs, medication attitudes, and habit strength.

DISCUSSION

This study specifically targets blood pressure and mental health symptom control in people with bipolar and includes implementation elements in the study design intended to inform future scale-up. Promising pilot data and a theoretical model, which views sustained medication-taking behavior in the context of habit formation, suggests that this remotely delivered intervention may help advance care for this high-risk population and is amenable to both scale up and easy adaptation for other groups with poor medication adherence.

TRIAL REGISTRATION

The study was registered at ClinicalTrials.gov ( NCT04675593 ) on December 19, 2020.

A Systematic Review and Meta-analysis of Face-to-face Medication Adherence Interventions for Patients with Long Term Health Conditions

BACKGROUND

Although previous reviews demonstrated effectiveness related to medication adherence interventions, they incorporated various digital platforms and other multiple delivery modes, which makes difficult to distinguish what aspects of the interventions led to effectiveness.

PURPOSE

This review aimed to (i) estimate the efficacy of face-to-face medication adherence interventions on adherence outcomes, in adults with Long Term Health Conditions (LTHCs) and (ii) identify the Behaviour Change Techniques (BCTs) used in the interventions and examine their potential impact on efficacy.

METHODS

Cochrane Controlled Register of Trials, Embase, MEDLINE (Ovid), PsycINFO, Web of Science, PubMed, and Scopus databases were searched. Randomized controlled trials were included if they described an intervention to improve medication adherence, delivered via face-to-face only, and included patients with LTHCs. Studies were excluded if they used additional delivery modes, involved family members or used a group format. In addition, use of BCTs was coded.

RESULTS

20 studies were included (n = 3667). Statistically significant pooled effects were found favoring the intervention than control, for the following MEMS (electronic monitoring) measures: percentage of prescribed doses taken on time over a period of 3 weeks to 2 months (MD 9.34, 95% CI 4.36-14.33, p = .0002; I2 =0%); percentage of prescribed doses taken for a period of 1 week to 2 months (MD 5.63, 95% CI 1.62-9.64, p = .006; I2 = 51%) and for 1 month (OR = 2.51, 95% CI 1.37-4.57, p = .003; I2 = 0%); percentage of days correct doses taken for 1 month to 14 weeks (MD 6.59, 95% CI 0.74-13.15, p = .03; I2 = 68%). Studies using the Morisky scale showed a significant between group difference for 1-3 months (MD 0.86, 95% CI 0.59-1.13, p < .00001; I2 = 0%). Overall, more BCTs were identified in intervention conditions than in comparison conditions (22 vs. 10). The impact of BCTs on intervention effectiveness could not be established as the analyses were underpowered.

CONCLUSIONS

Face-to-face interventions increased adherence to medication among adult patients with LTHCs. Although we were able to identify BCTs among interventions, data were insufficient to determine the impact of particular BCTs on intervention effectiveness.

The role of integrated medical and prescription drug plans in addressing racial and ethnic disparities in medication adherence

Medication nonadherence in the United States contributes to 125,000 deaths and 10% of hospitalizations annually. The pain of preventable deaths and the personal costs of nonadherence are borne disproportionately by Black, Latino, and other minority groups because nonadherence is higher in these groups due to a variety of factors. These factors include socioeconomic challenges, issues with prescription affordability and convenience of filling and refilling them, lack of access to pharmacies and primary care services, difficulty taking advantage of patient engagement opportunities, health literacy limitations, and lack of trust due to historical and structural discrimination outside of and within the medical system. Solutions to address the drivers of lower medication adherence, specifically in minority populations, are needed to improve population outcomes and reduce inequities. While various solutions have shown some traction, these solutions have tended to be challenging to scale for wider impact. We propose that integrated medical and pharmacy plans are well positioned to address racial and ethnic health disparities related to medication adherence. DISCLOSURES: This study was not supported by any funding sources other than employment of all authors by Humana Inc. Humana products and programs are referred to in this article.

Patient-Reported Barriers to Adherence Among ACEI/ARB Users from a Motivational Interviewing Telephonic Intervention

PURPOSE

Hypertension is a common comorbidity among type 2 diabetes mellitus (T2DM) patients, which increases the risk of cardiovascular diseases. Despite the proven benefit of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) in this population, poor medication adherence is prevalent, resulting in higher complications and mortality rate. Motivational interviewing (MoI) has demonstrated effectiveness in improving medication adherence and identifying barriers. This study aimed to assess and identify patient-reported barriers to adherence to ACEI/ARB from an MoI telephonic intervention conducted by student pharmacist interns.

PATIENTS AND METHODS

This retrospective study was conducted within an MoI intervention customized by past ACEI/ARB adherence trajectories for nonadherent patients with T2DM and hypertension enrolled in a Medicare Advantage Plan. Adherence barriers were extracted from the interviewers' notes by two independent researchers. Descriptive analysis was performed to summarize the overall frequency of barriers as well as across trajectory groups, identified from the initial and follow-up calls.

RESULTS

In total, 247 patients received the initial MoI call from which 41% did not communicate any barrier for ACEI/ARB use despite having low adherence. About 59% of the patients reported at least one barrier during the initial call. The most common barriers included forgetfulness, discontinuation by physicians, side effects, multiple comorbidities, polypharmacy, lack of knowledge about disease/medication, and cost issues. The follow-up calls helped with uncovering at least one new barrier for 28 patients who previously communicated a different issue with their medication during the first call. Additionally, 18 patients with initial denial for having any barrier to adherence reported at least one barrier throughout the follow-up calls.

CONCLUSION

This study summarized patient-reported barriers to ACEI/ARB adherence from an MoI telephonic intervention performed among nonadherent patients. Identifying specific barriers for patients may help to further design tailored interventions that address the barriers and improve adherence.

Is the Association between Herbal Use and Blood-Pressure Control Mediated by Medication Adherence? A Cross-Sectional Study in Primary Care

Herbs have been used worldwide for many health conditions as an alternative treatment, including hypertension. Their use might affect the use of conventional medications, as well as blood-pressure control. This study aims to determine whether the potential associations between herb use and high blood pressure in hypertensive patients was mediated by medication adherence. A cross-sectional study was conducted using questionnaires and available medical databases at a primary care clinic of a tertiary hospital in Chiang Mai, Thailand. The data were collected from 450 patients with essential hypertension. Drug adherence was assessed by the Morisky Green Levine Medication Adherence Scale. The history of herbs used in the past three months was obtained. The goal of controlled blood pressure was defined in accordance with the Thai guidelines on the treatment of hypertension. Of the total 450 patients, 42% had high adherence. Nearly 18% reported herb use in the past three months. High medication adherence was strongly associated with blood-pressure control when adjusted for age, gender, education, the presence of comorbidities, and herb use (aOR 26.73; 95% CI 8.58–83.23; p < 0.001). The association between herb use and blood-pressure control did not achieve statistical significance (p = 0.143). However, the adjusted odds ratio of the association between herb use and blood-pressure control was diluted from 0.67 to 0.83 when adding the factor of medication adherence to the model. In conclusion, herb use was associated with poor medication adherence, which was in turn associated with poor blood-pressure control. Assessing this information contributes to appropriate exploration and counseling.

Using group-based trajectory modeling to characterize the association of past ACEIs/ARBs adherence with subsequent statin adherence patterns among new statin users

BACKGROUND

Despite well-documented benefits, statin adherence remains suboptimal. Studies have suggested that previous adherence to other chronic medications is a strong predictor of future adherence to newly initiated statins. Group-based trajectory modeling (GBTM) has been applied as a method to longitudinally depict the dynamic nature of adherence.

OBJECTIVES

This study aimed to examine the association between patients' adherence patterns to newly initiated statins and previous adherence trajectories of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) using GBTM.

METHODS

This retrospective cohort study was conducted among continuously enrolled statin initiators using claims data. Patients were included if they had ACEI/ARB use within 1 year before statin initiation (preindex period). Monthly adherence to ACEIs/ARBs was calculated during the preindex period and monthly adherence to statins was assessed 1 year after statin initiation using proportion of days covered (PDC). The monthly PDCs were modeled as a longitudinal response in a logistic GBTM to provide distinct patterns of adherence for ACEIs/ARBs and statins, separately. A multinomial logistic regression was conducted to determine an association between ACEI/ARB adherence trajectories and future statin trajectories, controlling for patient characteristics.

RESULTS

A total of 1078 patients were categorized into 4 distinct statin adherence trajectories: adherent (40.8%), gradual decline (37.4%), gaps in adherence (13.9%), and rapid decline (7.9%). Patients were further categorized into 4 groups on the basis of their distinct past ACEIs/ARBs trajectories: adherent (43%), gaps in adherence (29%), delayed nonadherence (15.2%), and gradual decline (12.8%). In the multinomial logistic regression, patients in the gaps in adherence or gradual decline groups were more likely to follow similar trajectories for future statin use than the adherent trajectory.

CONCLUSION

Previous adherence trajectories of ACEIs/ARBs may predict future adherence patterns for newly initiated statins. Knowledge of past medication-taking behavior could provide valuable information for developing tailored interventions to improve adherence.

Effects of a pharmaceutical care intervention on clinical outcomes and patient adherence in coronary heart disease: the MIMeRiC randomized controlled trial

Background

In the treatment of coronary heart disease, secondary prevention goals are still often unmet and poor adherence to prescribed drugs has been suggested as one of the reasons. We aimed to investigate whether pharmaceutical care by a pharmacist at the cardiology clinic trained in motivational interviewing improves clinical outcomes and patient adherence.

Methods

This was a prospective, randomized, controlled, outcomes-blinded trial designed to compare pharmaceutical care follow-up with standard care. After standard follow-up at the cardiology clinic, patients in the intervention group were seen by a clinical pharmacist two to five times as required over seven months. Pharmacists were trained to use motivational interviewing in the consultations and they tailored their support to each patient’s clinical needs and beliefs about medicines. The primary study end-point was the proportion of patients who reached the treatment goal for low-density lipoprotein cholesterol by 12 months after discharge. The key secondary outcome was patient adherence to lipid-lowering therapy at 15 months after discharge, and other secondary outcomes were the effects on patient adherence to other preventive drugs, systolic blood pressure, disease-specific quality of life, and healthcare use.

Results

316 patients were included. The proportion of patients who reached the target for low-density lipoprotein cholesterol were 37.0% in the intervention group and 44.2% in the control group (P = .263). More intervention than control patients were adherent to cholesterol-lowering drugs (88 vs 77%; P = .033) and aspirin (97 vs 91%; P = .036) but not to beta-blocking agents or renin–angiotensin–aldosterone system inhibitors.

Conclusions

Our intervention had no positive effects on risk factors for CHD, but it increased patient adherence. Further investigation of the intervention process is needed to explore the difference in results between patient adherence and medication effects. Longer follow-up of healthcare use and mortality will determine if the increased adherence per se eventually will have a meaningful effect on patient health.

Development of a tablet app designed to improve African Americans' screening colonoscopy rates

Compared with other racial/ethnic groups, African Americans have the highest colorectal cancer (CRC) morbidity and mortality rates. It is critical to help improve African Americans' CRC prevention efforts in order to reduce the burden of CRC in this community. The aim of this study was to develop and field test a tablet app, called e-Motivate, designed to improve African Americans' screening colonoscopy rates. The e-Motivate app was field tested, using an iterative approach. The first version of the app, e-Motivate 1.0, was field tested on 20 African Americans over the age of 50. Participants engaged in a think aloud exercise and provided feedback regarding the app's usability and acceptability. The results of the first field test were used to modify the app and develop e-Motivate 2.0. The field test procedures were repeated on a new group of participants (N = 18). The results from the second field test were used to make final modifications to the app. Overall, participants responded positively to the app. Qualitative analyses showed that participants found the app to be easy to use and helpful. Furthermore, descriptive statistics revealed that participants found the app to be highly usable and acceptable, exceeding recommended benchmarks for usability and acceptability. Critiques of the app were used to modify and finalize the intervention. The results from the proposed study suggest that the e-Motivate app is highly feasible and acceptable. The next step in this line of research is to conduct a randomized clinical trial to formally test the efficacy of the e-Motivate app for improving screening colonoscopy rates among African Americans.

Motivational Interviewing Training for HIV Care Physicians in Argentina: Uptake and Sustainability of an Effective Behavior Change Intervention

Motivational interviewing (MI) utilizes a patient-centered approach to address patient ambivalence about treatment and has been found to improve treatment ART adherence among patients living with HIV disengaged from care. This study examined MI training for clinicians, uptake, and sustainability over time. Clinics (n = 7) with N = 38 physicians were randomized to condition (MI, Enhanced Standard of Care). Physicians completed video- recorded patient consultations at baseline and 6, 12, and 18-month follow-up. MI condition physicians had greater relational and technical scores over time and were more likely to adhere to and sustain MI over time. Overall, physicians found the MI training highly acceptable and were able to sustain their skills. Results illustrate the feasibility of MI training, implementation, and sustainment over 18 months. Findings support previous research in Argentina in which trained physicians found MI useful with challenging patients. Broader implementation of MI among HIV care physicians in Argentina is merited.

Effectiveness of motivational interviewing on medication adherence among Palestinian hypertensive patients: a clustered randomized controlled trial

BACKGROUND 

This trial aimed to evaluate the effectiveness of motivational interviewing (MINT) among medication non-adherent hypertensive patients attending primary healthcare centres in Gaza Strip.

METHODS AND RESULTS 

A clustered randomized controlled trial was run among 355 hypertensive participants; who were identified as non-adherent by a self-reported adherent scale and were recruited from 10 centres by two stages cluster random sampling approach (five centres were randomly allocated to each group). Standard of hypertension care was provided to 173 participants, parallel to 182 one who received their standard of care including non-blinded MINT sessions for 3 months. The change in medication adherence status was the primary outcome and within-patient changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), self-efficacy and intrinsic motivation were the secondary outcomes. Data were collected via an interview-based structured questionnaire and were analysed by generalizing equation estimation model adjusting for covariates. The results showed a significant improvement in medication adherence status among participants in the intervention group (n = 159) [OR= 6.28; 95% confidence interval (CI): 3.20, 12.33; P < 0.001] compared with those in the control group (n = 151). Moreover, there were significant drops in both SBP (OR = 0.18; 95% CI: 0.06, 0.55; P = 0.002) and DBP (OR = 0.26; 95% CI: 0.09, 0.76; P = 0.013) and significant positive changes in both within-patient's self-efficacy (OR = 15.4; 95% CI: 3.9, 60.6; P < 0.001) and intrinsic motivation (OR = 31.7; 95% CI: 13.9, 71.9; P < 0.001).

CONCLUSION 

Standard of care including MINT is an effective client-centred approach which promoted medication adherence, decreased mean blood pressure, and improved self-efficacy and intrinsic motivations among hypertensive patients.

Improving medication adherence in hypertensive patients: A scoping review

In recent years, interest in medication adherence has greatly increased. Adherence has been particularly well studied in the context of arterial hypertension treatment. Numerous interventions have addressed this issue, however, the effort to improve adherence has been often frustrating and frequently disorganized. The aim of present study was to perform a scoping review of medication adherence interventions in hypertensive patients, so that a clear overview was achieved. Moreover, an evidence-based categorization of interventions was developed. The review was performed according to the PRISMA-ScR statement. MEDLINE and Web of Science were searched, and studies published from database inception until August 17, 2020 were included. A total of 2994 non-duplicate studies were retrieved. After screening and eligibility phases, a total of 45 articles were included. Studies were analyzed regarding their design, participant characteristics and management of adherence strategies employed. Furthermore, medication adherence and blood pressure outcomes, as well as adherence measuring tools were evaluated. Each study's intervention was then categorized using a novel evidence-based system of categorization, derived from the conceptual clustering framework used in machine learning. This work is an important step in pushing for better informed and more efficient future research efforts, both by providing an overview of the research field and by creating a new, evidence-based intervention categorization tool. It also provides valuable information to clinicians about medication adherence to antihypertensive therapy.

Medication adherence in hypertension

: Suboptimal adherence to antihypertensive medication is a major contributor to poor blood pressure control. Several methods, direct or indirect, are available for measuring adherence, including the recently developed biochemical screening, although there is no gold-standard method routinely used in clinical practice to accurately assess the different facets of adherence. Adherence to treatment is a complex phenomenon and several of the barriers to adherence will need to be addressed at the healthcare system level; however, when looking at adherence from a more practical side and from the practitioner's perspective, the patient-practitioner relationship is a key element both in detecting adherence and in attempting to choose interventions tailored to the patient's profile. The use of single-pill combinations enabling simplification of treatment regimen, the implementation of a collaborative team-based approach and the development of electronic health tools also hold promise for improving adherence, and thus impacting cardiovascular outcomes and healthcare costs.

Undiagnosed Depression among Hypertensive Individuals in Gaza: A Cross-sectional Survey from Palestine

BACKGROUND

The aim of this study was to estimate the prevalence and to determine the associated factors of undiagnosed depression amongst hypertensive patients (HTNP) at primary health care centers (PHCC) in Gaza.

METHODS

A cross-sectional survey was conducted including 538 HTNP as a recruitment phase of a clustered randomized controlled trial. Data were collected through face-to-face structured interview, and depression status was assessed by Beck's Depression Inventory (BDI-II). Data were analyzed by STATA version 14 using standard complex survey analyses, accounted for unresponsiveness and clustering approach. Generalized linear regression analysis was performed to assess associations.

RESULTS

The prevalence of undiagnosed clinical depression was 11.6% (95% confidence interval [CI]: 8.1, 16.3). Moreover, prevalence of 15.4% (95% CI: 10.8, 21.6) was found for mild depression symptoms. We found that non-adherence to antihypertensive medications (AHTNM) (β = 0.9, 95% CI: 0.17, 1.7), having more health-care system support (β = 2.8, 95% CI: 1.6, 3.9) and number of AHTNM (β = 1.5, 95% CI: 0.6, 2.5) remain significantly positively associated with BDI-II score. On the other hand, older age (β = -0.1, 95% CI: -0.2, -0.02), having better social support (β = -6.8, 95% CI: -8.9, -4.7) and having stronger patient-doctor relationship (β = -4.1, 95% CI: -6.9, -1.2) kept significantly negative association.

CONCLUSION

The prevalence of undiagnosed depression was about one-quarter of all cases; half of them were moderate to severe. Routine screening of depression status should be a part of the care of HTNP in PHCC.

Tools and tactics for postdischarge medication management interventions

PURPOSE

To identify interventions for organizational pharmacist-leaders and frontline pharmacy staff to optimize peri- and postdischarge medication management.

SUMMARY

An evidence-based toolkit was systematically constructed on the basis of findings of 3 systematic overviews of systematic reviews. The interventions were reviewed by a technical expert panel and categorized as either tools or tactics. The identified tools are instruments such as diagrams, flow charts, lists, tables, and templates used in performing a distinct operation, whereas identified tactics reflect broader methods (eg, reduced dosing frequency). Tools and tactics were chosen on the basis of their potential to improve postdischarge medication management, with a focus on interventions led by pharmacy staff that may reduce hospital readmissions among older, sicker patients. Overall, 23 tools and 2 tactics were identified. The identified tools include items such as education, text messaging, and phone calls. The tactics identified are dose simplification and monetary incentives. Practical information has also been provided to facilitate implementation.

CONCLUSION

Several tools and tactics are available to optimize peri- and postdischarge medication management. Organizational pharmacist-leaders and frontline pharmacy staff can implement these interventions to improve patient outcomes.

Association of Perceived Stress and Discrimination on Medication Adherence among Diverse Patients with Uncontrolled Hypertension

Background

Uncontrolled hypertension is a significant risk factor for cardiovascular morbidity and mortality. In the United States, many patients remain uncontrolled, in part, due to poor medication adherence. Efforts to improve hypertension control include not only attending to medical management of the disease but also the social determinants of health, which impact medication adherence, and ultimately blood pressure control.

Purpose

To determine which social determinants - health care access or community and social stressors - explain medication adherence.

Methods

In this cross-sectional analysis, we used baseline data (N=1820, collected August 2017 to October 2019) from a pragmatic trial, which compares the effectiveness of a multi-level intervention including collaborative care and a stepped approach with enhanced standard of care for improving blood pressure. We used logistic regression analyses to examine the association between patient experiences of care and community and social stressors with medication adherence.

Results

The participants represented a diverse sample: mean age of 60 years; 59% female; 57.3% Black, 9.6% Hispanic, and 33.2% White. All participants had a blood pressure reading ≥140/90 mm Hg (mean blood pressure - 152/85 mm Hg). Half of the participants reported some level of non-adherence to medication. Regression analysis showed that, compared with Whites, Blacks (AOR .47; 95% CIs: .37-.60, P<.001) and Hispanics (AOR .48; 95% CIs: .32- .73, P<.001) were less likely to report medication adherence. Also part-time workers (AOR .57; 95% CIs: .38-.86, P<.05), and those who reported greater perceived stress (AOR .94; 95% CIs: .91 - .98, P<.001) and everyday discrimination (AOR .73; 95% CIs: .59 - .89; P<.001) had lower odds of medication adherence. Among Blacks, greater perceived stress (AOR .93; 95% CIs: .88-.98, P<.001) and everyday discrimination (AOR .63; 95% CIs: .49 - .82, P<.005) were negatively associated with medication adherence. Among Hispanics, greater report of everyday discrimination (AOR .36; 95% CIs: .14 - .89, P<.005) was associated with lower odds of medication adherence. Among Whites, the negative effect of perceived stress on medication adherence was attenuated by emotional support.

Conclusions

Using the social determinants of health framework, we identified associations between stress, everyday discrimination and medication adherence among non-Hispanic Blacks and Hispanics that were independent of health status and other social determinants. Programs to enhance self-management for African American and Hispanic patients with uncontrolled blood pressure should include a specific focus on addressing social stressors.

Evaluating trajectories of statin adherence after a motivational interviewing intervention

OBJECTIVE

The objective of the current study was to compare postintervention adherence trajectories with preintervention trajectories for those receiving a telephonic motivational interviewing (MoI) intervention to determine predictors associated with each distinct postintervention trajectory and any association between pre- and postintervention trajectories.

DESIGN

Retrospective study design using group-based trajectory modeling.

SETTINGS AND PARTICIPANTS

A telephonic MoI intervention was conducted by trained student pharmacists to improve statin adherence in a Medicare Advantage plan. Four preintervention adherence trajectories were previously identified: rapid decline (RD), gradual decline (GD), gaps in adherence (GA), and adherent and were used to customize the MoI intervention. Patients from the 3 nonadherent preintervention trajectories were randomized to control or intervention groups and were followed for 6 months from the date of MoI intervention.

OUTCOME MEASURES

Group-based trajectory modeling was performed to identify 3 relevant postintervention trajectories. Descriptive statistics were used to assess differences in pre- and postintervention adherence trajectories. Multinomial logistic regression was conducted to determine predictors associated with each identified postintervention trajectory.

RESULTS

There were 152 intervention patients and 304 randomly selected controls. The prominent postintervention trajectories that were identified differed from the preintervention trajectories and were (1) GD (17.2%), (2) adherent (61.9%), and (3) discontinuation (20.9%). Among the intervention group, more patients in the GA preintervention trajectory (58.65%) moved to the adherent trajectory postintervention than those in the RD and GD preintervention trajectories. Furthermore, the predictors associated with the postintervention trajectories included MoI intervention, prescriber specialty, presence of diabetes, presence of congestive heart failure, Centers for Medicare & Medicaid Services risk score, and preintervention trajectories.

CONCLUSION

The postintervention adherence trajectory patterns differed from the preintervention trajectory patterns with many patients moving into an adherent trajectory especially among those receiving the intervention.

The management of diabetes in everyday life study: Design and methods for a pragmatic randomized controlled trial comparing the effectiveness of text messaging versus health coaching

Background African American patients with uncontrolled diabetes living in medically underserved areas need effective clinic-based interventions to improve self-care behaviors. Text messaging (TM) and health coaching (HC) are among the most promising low-cost population-based approaches, but little is known about their comparative effectiveness in real-world clinical settings. Objective Use a pragmatic randomized controlled trial design to determine the comparative effectiveness of TM and HC with enhanced usual care (EC) in African American adults with uncontrolled diabetes and multiple chronic health conditions. Methods/design The Management of Diabetes in Everyday Life (MODEL) study is randomizing 646 patients (n = 581with anticipated 90% retention) to 3 intervention arms: TM, HC, and EC. Participants are African American adults living in medically underserved areas of the Mid-South, age ≥ 18, with uncontrolled diabetes (A1c ≥ 8), one or more additional chronic conditions, and who have a phone with texting and voicemail capability. Primary outcome measures: the general diet, exercise, and medication adherence subscales of the revised Summary of Diabetes Self-Care Activities questionnaire assessed at one year. Secondary outcomes: diabetes-specific quality of life, primary care engagement, and average blood sugar (A1c). The study will also assess heterogeneity of treatment effects by six key baseline participant characteristics. Conclusions We describe the design and methods of the MODEL study along with design revisions required during implementation in a pragmatic setting. This trial, upon its conclusion, will allow us to compare the effectiveness of two promising low-cost primary care-based strategies for supporting self-care behaviors among African Americans individuals with uncontrolled diabetes. ClinicalTrials.gov registration number: NCT02957513.

A Comparison of the Effects of Teach-Back and Motivational Interviewing on the Adherence to Medical Regimen in Patients with Hypertension

BACKGROUND AND OBJECTIVE

Arterial hypertension is considered a chronic medical problem and also a challenging condition. The present study aimed to compare the effects of motivational interviewing and teach-back on people with hypertension.

MATERIALS AND METHODS

In this clinical trial conducted in Yasuj in 2018 a total of 81 patients with essential hypertension were selected in terms of the inclusion criteria. Then, they were randomly divided into three groups: teach-back (Group 1), motivational interviewing (Group 2), and control (Group 3). Three teach-back sessions were held for the teach-back group, five sessions of motivational interviewing for the motivational interviewing group, and the routine care was provided for the control group. In addition, data were collected by the demographic form and scale of Adherence to Systemic Hypertension Treatment, which were completed by participants of all three groups at baseline and also two months from the intervention. Data were analyzed using SPSS 21 by applying descriptive statistics, one-way ANOVA, chi-squared test, Fisher's exact test, and Bonferroni test.

FINDINGS

Two months from the interventions, in Group 1, the score of adherence to the hypertension treatment regimen significantly increased by 816.38 points compared to the control group, in Group 2 by 1228.9 points compared to the control group, and in Group 2 by 412.6 points compared to Group 1 (p >0.05).

CONCLUSION

Both teach-back and motivational interviewing increased the adherence to the hypertension treatment regimen; however, motivational interviewing was more effective compared to teach-back in boosting adherence to the hypertension treatment regimen.

Using Motivational Interviewing to Increase PrEP Uptake Among Black Women at Risk for HIV: an Open Pilot Trial of MI-PrEP

Black women in the USA are at the highest risk among women for HIV. Pre-exposure prophylaxis (PrEP) prevents HIV transmission, but uptake among Black women remains low. An open pilot trial was conducted on MI-PrEP, a brief culturally tailored intervention incorporating motivational interviewing (MI) strategies to improve PrEP uptake and motivation. MI-PrEP is the first behavioral intervention developed to promote PrEP uptake among women in the USA. In Miami, FL, ten Black women who met eligibility criteria (e.g., sexual partner with HIV) were enrolled. These women participated in the two sessions of MI-PrEP and a 1-month follow-up. Participants completed measures on PrEP (motivation, uptake [verified via medical records], adherence, and barriers), medical mistrust, and an exit interview. These preliminary findings showed acceptability and feasibility with high satisfaction ratings; increases in PrEP uptake, knowledge, and motivation to use; and decreases in PrEP barriers and medical mistrust. Greater attention is needed on the psychosocial and structural factors among Black women who may benefit from PrEP.

A Glaucoma-Specific Brief Motivational Interviewing Training Program for Ophthalmology Para-professionals: Assessment of Feasibility and Initial Patient Impact

Our objective was to test the feasibility of, fidelity to, and initial impact of a brief, glaucoma-specific motivational interviewing (MI) training program for ophthalmic para-professionals. This prospective, mixed-methods study had two components, one for staff and one for patients. Staff fidelity to MI principles was graded through audio-recorded encounters after initial and final training sessions. After training, patients graded staff for adherence to autonomy supportive care. Semi-structured interviews with para-professionals elicited feedback about the training and about their ability to implement MI in the clinic. The impact on patient satisfaction with staff communication, eye drop instillation self-efficacy, and overall health activation was assessed using a survey pre- and post-training. Para-professionals met two of three program goals for MI skills and improved in their overall scores for MI fidelity. Para-professionals noted lack of time in the clinic as a significant barrier to implementing counseling. Patient satisfaction with staff communication increased after the training (p = 0.04) among patients who rated their staff above the mean for providing autonomy supportive care. The intervention did not improve patients' eye drop instillation self-efficacy or overall health activation. Training para-professional staff in brief, glaucoma-specific MI techniques is feasible and may improve patient satisfaction, though dedicated time in clinic is needed to implement MI counseling into glaucoma practice.

A Systems-Level Approach to Improving Medication Adherence in Hypertensive Latinos: a Randomized Control Trial

BACKGROUND

Despite numerous interventions targeting medication adherence in patients with uncontrolled hypertension, practice-based trials in Latino patients are scant.

OBJECTIVE

To evaluate the effect of a systems-level adherence intervention, delivered by medical assistants (MAs), versus a comparison condition on medication adherence and blood pressure (BP) in 119 hypertensive Latino patients who were initially non-adherent to their antihypertensive medications.

STUDY DESIGN

Randomized control trial.

PARTICIPANTS

Patients (50% women; mean age, 61 years) were recruited from April 2013 to August 2015 in a community-based practice in New York.

INTERVENTION

Systems-level approach that included an office system component built into the electronic health record and a provider support component consisting of nine MA-delivered health coaching sessions for improving medication adherence. The comparison group received the standard health coaching procedures followed at the clinic.

MAIN OUTCOME MEASURES

The primary outcome was rate of medication adherence measured by an electronic monitoring device (EMD) across 6 months. The secondary outcomes were self-reported medication adherence measured by the eight-item Morisky Medication Adherence Scale (MMAS-8) and BP reduction from baseline to 6 months.

KEY RESULTS

Adherence as measure by EMD worsened for both groups (p = 0.04) with no between-group difference (- 9.6% intervention and - 6.6% control, p = 0.66). While systolic BP improved in both groups, the difference between groups was not significant (- 6 mmHg in intervention vs. - 2.7 mmHg in control, p = 0.34). In contrast, the intervention group had a greater improvement in self-reported adherence (mean change 1.98 vs. 1.26, p = 0.03) when measured using the MMAS-8.

CONCLUSIONS

Among Latinos with poorly controlled BP who were non-adherent to their antihypertensive medications, a systems-level intervention did not improve adherence as measured by EMD nor blood pressure. However, many patients reported challenges to using the EMD. Improvements in self-reported adherence suggest that this measure captures different aspects of adherence behavior than EMD.

Enhancing Statin Adherence Using a Motivational Interviewing Intervention and Past Adherence Trajectories in Patients with Suboptimal Adherence

BACKGROUND

Statins have been shown to be effective in reducing the occurrence of cardiovascular (CV) events and are widely prescribed for the risk reduction of CV diseases and recurrent CV events. However, poor adherence prevents some patients from receiving the maximum benefit of the therapy. Motivational interviewing (MoI) is a patient-centered collaborative approach that can be used to improve medication adherence. Group-based trajectory modeling depicts patterns of adherence over time and may help tailor the MoI intervention to further enhance adherence.

OBJECTIVE

To assess the effect of a phone-based MoI intervention tailored by patients' past adherence trajectory in improving adherence to statins among patients in a Medicare Advantage prescription drug plan (MAPD).

METHODS

Patients continuously enrolled in an MAPD from 2013 to 2017 with a statin prescription between January and June 2015 to allow 2 years of pre-index period and 1 year of follow-up were included in the study. Adherence to statins was measured monthly during the 1-year follow-up as proportion of days covered (PDC) and incorporated into a group-based trajectory model to provide 4 distinct patterns of adherence: adherent, rapid decline, gradual decline, and gaps in adherence. Patients in the 3 nonadherent groups were randomized to either control or intervention. The intervention was an initial counseling call and up to 2 monthly follow-up calls by pharmacy students trained in MoI, providing education consistent with a previously identified pattern of use. Refill data at 6 months post-intervention were evaluated to examine the intervention's effect on PDC, as continuous and dichotomized as PDC ≥ 0.8, as well as discontinuation. Multivariable regression adjusted for baseline demographics, clinical characteristics, and past adherence trajectory.

RESULTS

There were 152 patients included in the analysis who received MoI phone calls and 304 randomly selected controls. Mean PDC for the intervention group (0.67 ± 0.3) was significantly higher than the control (0.55 ± 0.4; P < 0.001). The intervention group was also less likely to discontinue (OR = 0.38; 95% CI = 0.19-0.76) and more likely to be adherent in the linear regression model (β = 12.4; P < 0.001) as well as in the logistic regression model (OR = 1.87; 95% CI = 1.18-2.95). Previous adherence trajectories were significantly associated with adherence in the follow-up.

CONCLUSIONS

Patients who received the MoI intervention were more likely to be adherent and less likely to discontinue the statin in the 6 months follow-up compared with controls. Future research can identify other approaches to tailor interventions and expand the intervention to other languages. This intervention may also prove valuable to improve adherence to other medications for chronic and asymptomatic diseases.

Integrating Patient Education Into the Glaucoma Clinical Encounter: A Lean Analysis

PURPOSE

The main purpose of this study was to use Lean analysis to identify how often and when wait times occur during a glaucoma visit to identify opportunities for additional patient engagement.

METHODS

This prospective observational time-motion study measured process and wait times for 77 patient visits from 12 ophthalmologists at an academic glaucoma clinic over a 3-month period. Value stream maps visually diagramed the process of a clinical visit from the patient's perspective. Descriptive statistics were calculated for process times, wait times, and the frequency of 10+ minute wait times during each part of the visit. Key stakeholders participated in a root cause analysis to identify reasons for long wait times. The main outcome measure was average times (hours: minutes: seconds) for process times and wait times.

RESULTS

Twenty-nine new visit (NV) patients and 48 return visit (RV) patients were included. Total time in clinic was 187.1±44.5 (mean±SD) minutes for NV patients and 102.0±44.7 minutes for RV patients. Wait time for NV patients was 63.7±33.4 minutes (33.1% of total appointment time) and for RV patients was 52.6±31.6 minutes (49.4% of the total appointment time). All NV patients and 87.5% of RV patients had at least one 10+ minute wait time during their clinic visit and the majority (75.9% NV, 60.4% RV) had >1.

CONCLUSIONS

Currently, sufficient wait time exists during the visit for key portions of glaucoma education such as teaching eye drop instillation.

Interventions to Improve Medication Adherence: A Review

IMPORTANCE

Among adults with chronic illness, 30% to 50% of medications are not taken as prescribed. In the United States, it is estimated that medication nonadherence is associated with 125 000 deaths, 10% of hospitalizations, and $100 billion in health care services annually.

OBSERVATIONS

PubMed was searched from January 1, 2000, to September 6, 2018, for English-language randomized clinical trials of interventions to improve medication adherence. Trials of patients younger than 18 years, trials that used self-report as the primary adherence outcome, and trials with follow-up periods less than 6 months were excluded; 49 trials were included. The most common methods of identifying patients at risk for nonadherence were patient self-report, electronic drug monitors (pill bottles), or pharmacy claims data to measure gaps in supply. Patient self-report is the most practical method of identifying nonadherent patients in the context of clinical care but may overestimate adherence compared with objective methods such as electronic drug monitors and pharmacy claims data. Six categories of interventions, and characteristics of successful interventions within each category, were identified: patient education (eg, recurrent and personalized telephone counseling sessions with health educators); medication regimen management (using combination pills to reduce the number of pills patients take daily); clinical pharmacist consultation for chronic disease co-management (including education, increased frequency of disease monitoring via telephone or in-person follow-up visits, and refill reminders); cognitive behavioral therapies (such as motivational interviewing by trained counselors); medication-taking reminders (such as refill reminder calls or use of electronic drug monitors for real-time monitoring and reminding); and incentives to promote adherence (such as reducing co-payments and paying patients and clinicians for achieving disease management goals). The choice of intervention to promote adherence will depend on feasibility and availability within a practice or health system. Successful interventions that are also clinically practical include using combination pills to reduce daily pill burden, clinical pharmacist consultation for disease co-management, and medication-taking reminders such as telephone calls to prompt refills (maximum observed absolute improvements in adherence of 10%, 15%, and 33%, respectively).

CONCLUSIONS AND RELEVANCE

Adherence can be assessed and improved within the context of usual clinical care, but more intensive and costly interventions that have demonstrated success will require additional investments by health systems.

Culturally tailored, peer-based sleep health education and social support to increase obstructive sleep apnea assessment and treatment adherence among a community sample of blacks: study protocol for a randomized controlled trial

BACKGROUND

Compared to whites, blacks are at increased risk for obstructive sleep apnea (OSA) yet less likely to adhere to physician-recommended sleep assessment and treatment. Poor OSA health literacy and lack of social support to navigate the current healthcare system are two potential barriers to adequate OSA care. This study is designed to address these barriers by evaluating the effectiveness of a peer-based sleep health education program on adherence to OSA assessment and treatment among blacks at risk for OSA.

METHOD/DESIGN

In a two-arm, randomized controlled trial, we will ascertain the effectiveness of peer-based sleep health education and social support in increasing OSA evaluation and treatment rates among 398 blacks at low to high OSA risk. Participants at risk of OSA will receive quality controlled, culturally, and linguistically tailored peer education based on Motivational Enhancement principles over a period of 12 months. During this 12-month period, participants are encouraged to participate in a sleep home study to determine risk of OSA and, if found to be at risk, they are invited to undergo a diagnostic sleep assessment at a clinic. Participants who are diagnosed with OSA and who are prescribed continuous positive airway pressure treatment will be encouraged, through peer-based education, to adhere to recommended treatment. Recruitment for the project is ongoing.

DISCUSSION

The use of a culturally tailored sleep health education program, peer health educators trained in sleep health, and home-based sleep assessment are novel approaches in improving OSA assessment and treatment adherence in blacks who are significantly at risk for OSA. Empirical evidence from this trial will provide clinical and population level solutions on how to improve and increase assessment and treatment of OSA among blacks.

Physician-delivered motivational interviewing to improve adherence and retention in care among challenging HIV-infected patients in Argentina (COPA2): study protocol for a cluster randomized controlled trial

BACKGROUND

"Challenging" HIV-infected patients, those not retained in treatment, represent a critical focus for positive prevention, as linkage to care, early initiation of antiretroviral therapy, adherence and retention in treatment facilitate viral suppression, thus optimizing health and reducing HIV transmission. Argentina was one of the first Latin American countries to guarantee HIV prevention, diagnosis and comprehensive care services, including antiretroviral medication, which removed cost and access as barriers. Yet, dropout occurs at every stage of the HIV continuum. An estimated 110,000 individuals are HIV-infected in Argentina; of these, 70% have been diagnosed and 54% were linked to care. However, only 36% have achieved viral suppression and 31% of those diagnosed delayed entry to care. To achieve meaningful reductions in HIV infection at the community level, innovative strategies must be developed to re-engage patients. Motivational Interviewing (MI) is a patient-centered approach and has been used by therapists in Central and South America to enhance motivation and commitment in substance use and risk reduction. Our pilot feasibility study utilized culturally tailored MI in physicians to target patients not retained in treatment in public and private clinics in Buenos Aires, Argentina. Results demonstrated that a physician-based MI intervention was feasible and effective in enhanced and sustained patient adherence, viral suppression, and patient-physician communication and attitudes about treatment among these patients at 6 and 9 months post baseline.

METHODS/DESIGN

This clinical trial seeks to extend these findings in public and private clinics in four urban population centers in Argentina, in which clinics (n = 6 clinics, six MDs per clinic site) are randomized to experimental (physician MI Intervention) (n = 3) or control (physician Standard of Care) (n = 3) conditions in a 3:3 ratio. Using a cluster randomized clinical trial design, the study will test the effectiveness of a physician-based MI intervention to improve and sustain retention, adherence, persistence, and viral suppression among "challenging" patients (n = 420) over 24 months.

DISCUSSION

Results are anticipated to have significant public health implications for the implementation of MI to re-engage and retain patients in HIV treatment and care and improve viral suppression through high levels of medication adherence.

High treatment adherence, satisfaction, motivation, and health-related quality of life with fingolimod in patients with relapsing-remitting multiple sclerosis - results from a 24-month, multicenter, open-label Danish study

PURPOSE

Treatment adherence is a prerequisite for treatment success and therefore an important consideration to assure that therapeutic goals are achieved both from a patient point of view and for optimal health care resource utilization. Published data on treatment adherence with fingolimod (Gilenya®) are limited. Therefore, this study investigated treatment adherence in patients with relapsing-remitting multiple sclerosis (RRMS) treated with fingolimod in Denmark.

PATIENTS AND METHODS

This was a 24-month, multicenter, open-label study, investigating treatment adherence, satisfaction, motivation, and health-related quality of life (QoL) in RRMS patients treated with fingolimod. In addition, the effect of a motivational interview support program on these measures was evaluated. Treatment adherence was assessed by pill count. Treatment satisfaction, motivation, and QoL were assessed by patient-reported outcomes (PROs).

RESULTS

A total of 195 patients were enrolled in the study. A very high treatment adherence was observed during the entire study with no statistically significant difference between study visits before (99%) and after (97%) the motivational interview. In accordance, a high level of treatment satisfaction was found in the Treatment Satisfaction Questionnaire for Medication 9, which was scored high throughout the study with the highest scores seen for the convenience domain (ranging from 94.51 to 95.78). Furthermore, additional PROs demonstrated a high health-related QoL, a self-determined form of motivation for taking medication, and a patient perception of an autonomy supportive approach provided by the health care provider, at all study visits.

CONCLUSION

High levels of treatment adherence, satisfaction, motivation, and QoL were observed in Danish RRMS patients treated with fingolimod. As these positive measures were observed at all study visits and throughout the study, no effect of the motivational interview support program was found.

Addressing the Social Needs of Hypertensive Patients: The Role of Patient-Provider Communication as a Predictor of Medication Adherence

BACKGROUND

Poor medication adherence is a pervasive problem in patients with hypertension. Despite research documenting an association between patient-provider communication and medication adherence, there are no empirical data on how the informational and relational aspects of communication affect patient's actual medication-taking behaviors. The aim of this study was to evaluate the impact of patient-provider communication on medication adherence among a sample of primary care providers and their black and white hypertensive patients.

METHODS AND RESULTS

Cohort study included 92 hypertensive patients and 27 providers in 3 safety-net primary care practices in New York City. Patient-provider encounters were audiotaped at baseline and coded using the Medical Interaction Process System. Medication adherence data were collected continuously during the 3-month study with an electronic monitoring device. The majority of patients were black, 58% women, and most were seeing the same provider for at least 1 year. Approximately half of providers were white (56%), 67% women, and have been in practice for an average of 5.8 years. Fifty-eight percent of patients exhibited poor adherence to prescribed antihypertensive medications. Three categories of patient-provider communication predicted poor medication adherence: lower patient centeredness (odds ratio: 3.08; 95% confidence interval: 1.04-9.12), less discussion about patients' sociodemographic circumstances (living situation, relationship with partner; odds ratio: 6.03; 95% confidence interval: 2.15-17), and about their antihypertensive medications (odds ratio: 6.48; 95% confidence interval: 1.83-23.0). The effect of having less discussion about patients' sociodemographic circumstances on medication adherence was heightened in black patients (odds ratio: 8.01; 95% confidence interval: 2.80-22.9).

CONCLUSIONS

The odds of poor medication adherence are greater when patient-provider interactions are low in patient centeredness and do not address patients' sociodemographic circumstances or their medication regimen.

Toward an Emerging Role for Motivational Interviewing in Primary Care

PURPOSE OF REVIEW

Implementing Motivational Interviewing (MI) in primary care settings has been problematic due in part to persistent gaps in knowledge. Examples include poor understanding of how to effectively train persons to conduct MI, or of which aspects of MI-related communication are associated with better outcomes for patients. This review describes how recent research findings addressing the knowledge gaps support a growing role for MI in primary care.

RECENT FINDINGS

Two trials of MI training combined classroom time with ongoing coaching and feedback, resulting in enhanced MI ability relative to a control arm where PCPs received minimal or no MI training. A third MI training trial excluded coaching and feedback, failing to increase use of MI. Adding to a growing list of behavioral health-related problems for which MI training has shown some effectiveness, a trial of training PCPs to use MI with depressed patients was associated with significantly improved depressive symptoms. Moreover, aspects of the PCPs' MI-related language and patients' arguments for positive behavior changes, "change talk," appeared to explain the positive effects of MI training on depression outcome. MI-training approaches have improved such that PCPs and possibly other clinic staff may want to consider MI training as a way to more effectively support their patients as they address behavioral health-related problems (e.g., tobacco use). MI training should focus on eliciting "change talk" from patients. Researchers and funding agencies might collaborate to continue closing knowledge gaps in the MI literature.

Effectiveness of motivational interviewing interventions on medication adherence in adults with chronic diseases: a systematic review and meta-analysis

Background

Medication adherence is frequently suboptimal in adults with chronic diseases, resulting in negative consequences. Motivational interviewing (MI) is a collaborative conversational style for strengthening a person's motivation and commitment to change. We aimed to assess whether MI interventions are effective to enhance medication adherence in adults with chronic diseases and to explore the effect of individual MI intervention characteristics.

Methods

We searched electronic databases and reference lists of relevant articles to find randomized controlled trials (RCTs) that assessed MI intervention effectiveness on medication adherence in adults with chronic diseases. A random-effects model was used to estimate a pooled MI intervention effect size and its heterogeneity (I 2 ). We also explored the effects of individual MI characteristics on MI intervention effect size using a meta-regression with linear mixed model.

Results

: Nineteen RCTs were identified, and 16 were included in the meta-analysis. The pooled MI intervention effect size was 0.12 [95% confidence interval (CI) = (0.05, 0.20), I 2 = 1%]. Interventions that were based on MI only [β = 0.183, 95% CI = (0.004, 0.362)] or those in which interventionists were coached during intervention implementation [β = 0.465, 95% CI = (0.028, 0.902)] were the most effective. MI interventions that were delivered solely face to face were more effective than those that were delivered solely by phone [β = 0.270, 95% CI = (0.041, 0.498)].

Conclusions

This synthesis of RCTs suggests that MI interventions might be effective at enhancing of medication adherence in adults treated for chronic diseases. Further research is however warranted, as the observed intervention effect size was small.

Drug Adherence in Patients With Nonvalvular Atrial Fibrillation Taking Non-Vitamin K Antagonist Oral Anticoagulants in Turkey: NOAC-TR

Adherence to non-vitamin K antagonist oral anticoagulants (NOACs) is an important factor for ensuring efficacy and safety in nonvalvular atrial fibrillation (NVAF). There are controversial results regarding NOAC adherence in real-world data and there are no data about NOAC adherence in Turkish population. This study investigated the NOAC adherence based on self-report, factors affecting nonadherence, and the relation of the adherence level with efficacy and safety outcomes. This multicenter cross-sectional study included 2738 patients (59% female) using NOAC (dabigatran, apixaban, and rivaroxaban) due to NVAF for more than 3 months with >30 days of supply between September 1, 2015, and February 28, 2016. To measure the adherence level, an 8-item Morisky Medication Adherence Scale was used. The mean age of the patients was 70 ± 10 years. Of the 2738 patients, 44% were receiving dabigatran, 38% rivaroxaban, and 18% apixaban. A total of 630 (23%) patients had high medication adherence, 712 (26%) moderate adherence, and 1396 (51%) low adherence. Nonadherence had related to stroke (5.6% vs 2.5%, P < .001) and minor (21.2% vs 11.1%, P < .001) and major (6.1% vs 3.7%, P = .004) bleeding rates. The adherence to NOAC was found to be quite low in Turkey. Nonadherence is associated with bleeding and thromboembolic cardiovascular events. Age, taking NOAC twice a day, and the additional noncardiac diseases, depression, and dementia were the independent factors affecting poor medication adherence.
