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

"They Ask Questions, But They Don't Want the Answers"-Perceptions of Clinical Communication Among Veterans Discontinuing Buprenorphine for the Treatment of Opioid Use Disorder

BACKGROUND

Many patients with opioid use disorder (OUD) discontinue treatment prematurely, increasing their risk of opioid-related overdose and death. While patient-centered care is considered the gold standard in treating chronic illness, it may be practiced less frequently in the context of OUD care. Patient-provider communication can influence patients' care experiences, potentially having an impact on treatment retention and care decision-making.

METHODS

This study was conducted at the VA Portland Health Care System from March 2021 to April 2022. We conducted qualitive interviews with patients who had discontinued buprenorphine for the treatment of OUD within the past year. Coding and analysis were guided by inductive qualitative content analysis. Retrospective medical record review identified clinical and demographic characteristics of participants.

RESULTS

Twenty patients completed an interview. Participant age ranged from 28 to 74 years (median 63 years). Ninety percent of participants were white and 90% male. Many participants expressed frustration and feelings of disempowerment in OUD care processes. Patients with a history of long-term prescribed opioid use frequently expressed stigmatizing views of OUD, and perceptions of disagreement with providers over diagnosis and care choices. Elderly patients and those with multiple comorbidities expressed confusion over significant aspects of their care, as well as difficulty navigating treatment logistics like appointment requirements and medication dose changes. Some patients reported later restarting buprenorphine in new settings, and described feeling respected and involved in care decisions as a facilitator for continuing treatment.

CONCLUSIONS

Prioritizing patient-centered communication in OUD treatment could improve the patient experience and potentially support treatment retention. Subgroups of OUD patients, such as those with a history of long-term prescribed opioid use, elderly patients with multiple comorbidities, or those who express stigmatizing medication views, could particularly benefit from tailored communication strategies that address their individual concerns.

What do patients with heart failure disclose about medication adherence at home to their hospital and primary care doctors? Exploratory interaction-based observational cohort study

OBJECTIVES

The main objective of this study was twofold: to investigate what kind of information patients with heart failure (HF) tell their doctors about their medication adherence at home, and how often such information is provided in consultations where medication reconciliation is recommended. To meet these objectives, we developed an analysis to recognise, define, and count (1) patient utterances including medication adherence disclosures in clinical interactions (MADICI), (2) MADICI including red-flags for non-adherence, and (3) MADICI initiated by patients without prompts from their doctor.

DESIGN

Exploratory interaction-based observational cohort study. Inductive microanalysis of authentic patient-doctor consultations, audio-recorded at three time-points for each patient: (1) first ward visit in hospital, (2) discharge visit from hospital, and (3) follow-up visit with general practitioner (GP).

SETTING

Norway (2022-2023).

PARTICIPANTS

25 patients with HF (+65 years) and their attending doctors (23 hospital doctors, 25 GPs).

RESULTS

We recognised MADICI by two criteria: (1) they are about medication prescribed for use at home, AND (2) they involve patients' action, experience, or stance regarding medications. Using these criteria, we identified 427 MADICIs in 25 patient trajectories: 143 (34%) at first ward visit (min-max=0-35, median=3), 57 (13%) at discharge visit (min-max=0-8, median=2), 227 (53%) at GP-visit (min-max=2-24, median=7). Of 427 MADICIs, 235 (55%) included red-flags for non-adherence. Bumetanide and atorvastatin were most frequently mentioned as problematic. Patients initiated 146 (34%) of 427 MADICIs. Of 235 'red-flag MADICIs', 101 (43%) were initiated by patients.

CONCLUSIONS

Self-managing older patients with HF disclosed information about their use of medications at home, often including red-flags for non-adherence. Patients who disclosed information that signals adherence problems tended to do so unprompted. Such disclosures generate opportunities for doctors to assess and support patients' medication adherence at home.

Medication Adherence in Adults with Chronic Diseases in Primary Healthcare: A Quality Improvement Project

(1) Background: Medication adherence is influenced by a variety of intricate factors, presenting hurdles for nurses working to improve it among adults with chronic conditions. Pinpointing the reasons for non-adherence is crucial for customizing interventions. The objective of this quality improvement project was to improve medication adherence among adults with chronic diseases in primary healthcare by promoting evidence-based practices, identifying barriers and facilitators to compliance, and developing strategies to ensure optimal adherence through engaging the nursing team, enhancing knowledge, and evaluating the effectiveness of the implemented strategies. (2) Methods: This study was a quality improvement project that utilized the JBI Evidence Implementation framework, the Practical Application of Clinical Evidence System, and the Getting Research into Practice audit tool across three phases: (i) forming a project team and conducting a baseline audit, (ii) offering feedback via the GRiP tool, and (iii) conducting a follow-up audit to assess best practice outcomes. The study was conducted between September 2021 and March 2022 in the community care unit of Algarve Regional Health Administration, targeting adults with chronic illnesses. (3) Results: A total of 148 individuals were audited, including 8 nurses, 70 baseline patients, and 70 post-implementation patients. Initial compliance with key best practices was low, with several criteria at 0% compliance at baseline. Post-intervention, we observed significant improvements; compliance with key best practices improved dramatically, with many reaching 100%. Notable improvements included enhanced patient education on medication management, regular medication adherence assessments, and increased engagement of healthcare professionals in adherence activities. (4) Conclusions: This quality improvement project demonstrated that structured, evidence-based interventions could significantly enhance medication adherence among adults with chronic diseases. The success of the project highlights the potential of similar strategies to be applied broadly in primary healthcare settings to improve health outcomes.

A Qualitative Study on Dentists' Communication Approaches in Managing Fluoride-Hesitant Caregivers

OBJECTIVES

Guidelines on effective provider-led communication are available but may be underused in dentistry, even if such guidelines could help dentists manage complex clinical scenarios like topical fluoride hesitancy. The purpose of this study was to investigate current chairside communication approaches used by dentists with fluoride-hesitant caregivers.

METHODS

A 27-item semistructured interview script was developed and pretested with 3 dentists, revised, and finalized. One-on-one interviews were conducted with a purposive sample of pediatric dentists and general dentists from April to June 2020. Interviews were digitally recorded, transcribed, and analyzed to identify dentists' communication approaches used during clinical interactions with fluoride-hesitant caregivers. Thematic analyses identified themes and subthemes, and exemplary quotes were provided to illustrate each theme.

RESULTS

Twenty-seven dentists participated (21 pediatric dentists and 6 general dentists). The mean age of participants was 43.0 ± 8.2 y (range, 30-73). Most participants were women (88.9%), white (51.9%), and non-Hispanic (85.2%). Participants had been practicing dentistry for a mean of 13.2 ± 10.5 y (range, 2-40). There were 4 themes: leaving topical fluoride decisions completely up to the caregiver, educating the caregiver about fluoride, insisting that the caregiver accept fluoride, and engaging the caregiver and child.

CONCLUSION

Most communications approaches used by interviewed dentists to manage fluoride hesitancy in clinical settings are not evidence based. Future dental education efforts should ensure that trainees are exposed to and can demonstrate competency in appropriate, evidence-based patient-provider communication strategies.

KNOWLEDGE TRANSFER STATEMENT

The study highlights the need for dentists to apply evidence-based communication strategies when managing difficult clinical scenarios like fluoride hesitancy, which is important in optimizing dentist-patient trust.

Adherence to Antihypertensive Therapy and Its Determinants: A Systematic Review

Hypertension is a globally prevalent condition, and low adherence to antihypertensive therapy is considered one of the main causes of poor blood pressure (BP) control. Non-adherence to antihypertensive treatment is a complex issue that can arise from various factors; however, gaining an understanding of this provides key targets for intervention strategies. This study aimed to provide an overview of the current status and recent developments regarding our understanding of the determinants of patients' adherence to antihypertensives. A systematic review was performed using the electronic databases MEDLINE/PubMed, Web of Science, Scientific Electronic Library Online (SciELO), and "Índex das Revistas Médicas Portuguesas", which included studies published between 2017 and 2021 following the PICOS model: (P) Adult patients with the diagnosis of primary hypertension, using at least one antihypertensive agent; (I) all interventions on both pharmacological and non-pharmacological level; (C) patient's adherence against their non-adherence; (O) changes in adherence to the therapeutic plan; and (S) any study design (except review articles) written in English, French, Spanish or Portuguese. Articles were reviewed by two researchers and their quality was assessed. Subsequently, determinants were classified according to their consistent or inconsistent association with adherence or non-adherence. Only 45 of the 635 reports identified met the inclusion criteria. Adherence was consistently associated with patient satisfaction with communication, patient-provider relationship, their treatment, and use of eHealth and mHealth strategies; a patient's mental and physical health, including depression, cognitive impairment, frailty, and disability, previous hospitalization, occurrence of vital events; drug treatment type and appearance; and unwillingness due to health literacy, self-efficacy, and both implicit and explicit attitudes towards treatment. There were discrepancies regarding the association of other factors to adherence, but these inconsistent factors should also be taken into account. In conclusion, the barriers to adherence are varied and often interconnected between socioeconomic, patient, therapy, condition, and healthcare system levels. Healthcare teams should invest in studying patients' non-adherence motives and tailoring interventions to individual levels, by using a multifaceted approach to assess adherence. Further research is needed to analyze the impact of implicit attitudes, the use of new technological approaches, and the influence of factors that are inconsistently associated with non-adherence, to understand their potential in implementing adherence strategies.

Linking Cardiac Psychology and Cardiovascular Medicine via Self-Determination Theory and Shared Decision-Making

Despite considerable progress in recent years, research in cardiac psychology is not widely translated into routine practice by clinical cardiologists or clinical health psychologists. Self-determination theory (SDT), which addresses how basic psychological needs of autonomy, competence, and relatedness contribute to the internalization of motivation, may help bridge this research-practice gap through its application to shared decision-making (SDM). This narrative review discusses the following: (a) brief background information on SDT and SDM, (b) the application of SDT to health behavior change and cardiology interventions, and (c) how SDT and SDM may be merged using a dissemination and implementation (D&I) framework. We address barriers to implementing SDM in cardiology, how SDM and SDT address the need for respect of patient autonomy, and how SDT can enhance D&I of SDM interventions through its focus on autonomy, competence, and relatedness and its consideration of other constructs that facilitate the internalization of motivation.

Frequency and nature of discussing social influences on health in urban safety-net clinics: A qualitative analysis

OBJECTIVE

Chronic social isolation is a risk factor for all-cause mortality and disease progression, but is not routinely screened for in clinical settings. This study analyzed provider-patient communication patterns about social influences during primary care encounters, to identify opportunities to screen for objective or perceived social isolation.

METHODS

Content analysis was conducted on transcripts of 97 audiotaped, English-speaking patient encounters with 27 primary care providers at 3 safety-net primary care centers in New York City. Conversations were first coded for specific social isolation screening, then more broadly to quantify and qualify how social influences were discussed in relation to health.

RESULTS

Transcripts included no explicit examples of social isolation screening. Social influences on health were discussed meaningfully in only 28 % of transcripts, compared to medication adherence (93 %) and diet (64 %). Patients initiated conversations about social influences on health twice as often as providers, however providers did not acknowledge 67% of these prompts.

CONCLUSION

Social influences on health, including social isolation, were uncommonly discussed in this sample of primary care visits. When social influences were discussed meaningfully, providers utilized relationship-centered communication strategies.

PRACTICE IMPLICATIONS

Strategic conversations about social influences, even when brief and informal, can effectively screen patients for social isolation.

The mobilization of nurse-client therapeutic relationships in injectable opioid agonist treatment: Autonomy, advocacy and action

INTRODUCTION

Injectable opioid agonist treatment (iOAT) is an evidence-based treatment that serves an important minority of people with opioid use disorder who require specialized care. Unique to iOAT care is the consistency with which clients access treatment (up to three times daily), a condition that creates repeated opportunities for health care engagement. To date, no study has examined therapeutic relationships in this life saving, nurse-led treatment that can have lasting implications in the equitable delivery of other forms of addictions care.

METHODS

This study used grounded theory to generate a dynamic framework for therapeutic relationship building in iOAT. Researchers collected semi-structured interviews from registered nurses working in iOAT sites (n=24) form January 2020 through June 2022. The study analyzed collected data through a constant comparative analysis; explored through open, axial, and selective coding; and assessed in a conditional relationship matrix. The team reviewed key findings with stakeholders through formalized processes of engagement to confirm saturation of coding categories. Throughout data collection and analysis, researchers integrated feedback from additional knowledge users and member checking. Reported findings adhered to the COREQ1 standardized checklist.

RESULTS

We identified five interrelated categories that created a distinct culture of care for iOAT nurses: Ways of Knowing, Personal Investment, Leveraging Empathy, Finding Flexibility, and Collaborating to Overcome. Through creating a safe, nonjudgmental environment, nurses establish therapeutic relationships that build trust to identify client needs outside of medication administration. In turn, nurses participate in team-based problem solving to advocate for client needs. If nurses cannot find flexibility within and outside of the health care system to improve client engagement, tensions can arise and therapeutic relationships can be strained.

CONCLUSIONS

Therapeutic relationships are an integral part of building and maintaining trust with a population that has been precariously involved with other forms of health care. Nurses make a substantial effort to create a safe and nonjudgmental environment to manifest a culture of care that bridges client needs and program access. Without the expansion of access to iOAT programs and their embedded services, nurses are limited in their ability to provide individualized care for clients with diverse needs.

Emotional Intelligence: A Novel Factor Influencing Hypertension Self-Management

The purpose of this study was to examine associations among emotional intelligence, quality of patient-provider interaction, and hypertension (HTN) self-management behaviors. A convenience sample of 90 adults (predominately African American women) with primary HTN were recruited from an urban ambulatory internal medicine clinic. Multivariate linear regression models were used to determine the predictive associations among the study variables. Emotional intelligence was associated with the quality of the patient-provider interaction (r = 0.34; p < .001), patient activation (r = 0.56; p < .001), and medication use (r = 0.26; p = .006). The patient-provider interaction was associated with higher states of patient activation (r = 0.42; p < .001) and medication use behavior (r = 0.29; p = .002). Also, the quality of patient-provider interaction partially mediated the relationship between emotional intelligence and self-management behaviors. Emotional intelligence is a promising patient factor that influences quality of patient-provider interaction and self-management behaviors.

Effectiveness of a provider and patient-focused intervention to improve hypertension management and control in the primary health care setting in Cuba: a controlled before-after study

BACKGROUND

Implementation research to improve hypertension control is scarce in Latin America. We assessed the effectiveness of an intervention aimed at primary care practitioners and hypertensive patients in a setting that provides integrated care through an accessible network of family practices.

METHODS

We conducted in Cardenas and Santiago, Cuba, a controlled before-after study in 122 family practices, which are staffed with a doctor and a nurse. The intervention comprised a control arm (usual care), an arm with a component targeting providers (hypertension management workshops), and an arm with, on top of the latter, a component targeting patients (hypertension schools). To evaluate the effect, we undertook a baseline survey before the intervention and an endline survey sixteen months after its start. In each survey, we randomly included 1400 hypertensive patients. Controlled hypertension, defined as a mean systolic and diastolic blood pressure below 140 and 90 mmHg, respectively, was the primary endpoint assessed. We performed linear and logistic regression with a Generalized Estimating Equations approach to determine if the proportion of patients with controlled hypertension changed following the intervention.

RESULTS

Seventy-three doctors, including substitutes, and 54 nurses from the 61 intervention family practices attended the provider workshops, and 3308 patients -51.6% of the eligible ones- participated in the hypertension schools. Adherence to anti-hypertensive medication improved from 42% at baseline to 63% at the endline in the intervention arms. Under the provider intervention, the proportion of patients with controlled hypertension increased by 18.9%, from 48.7% at baseline to 67.6% at endline. However, adding the component that targeted hypertensive patients did not augment the effect. Compared to patients in the control arm, the adjusted OR of having controlled hypertension was 2.36 (95% CI, 1.73-3.22) in the provider and 2.00 (95% CI, 1.68-2.37) in the provider plus patient intervention arm.

CONCLUSIONS

The intervention's patient component remains to be fine-tuned. Still, we demonstrate that it is feasible to substantially improve hypertension outcomes by intervention at the primary care level, despite an already relatively high control rate.

New perspectives for hypertension management: progress in methodological and technological developments

Hypertension is the most common and preventable risk factor for cardiovascular disease (CVD), accounting for 20% of deaths worldwide. However, 2/3 of people with hypertension are undiagnosed, untreated, or under treated. A multi-pronged approach is needed to improve hypertension management. Elevated blood pressure (BP) in childhood is a predictor of hypertension and CVD in adulthood; therefore, screening and education programmes should start early and continue throughout the lifespan. Home BP monitoring can be used to engage patients and improve BP control rates. Progress in imaging technology allows for the detection of preclinical disease, which may help identify patients who are at greatest risk of CV events. There is a need to optimize the use of current BP control strategies including lifestyle modifications, antihypertensive agents, and devices. Reducing the complexity of pharmacological therapy using single-pill combinations can improve patient adherence and BP control and may reduce physician inertia. Other strategies that can improve patient adherence include education and reassurance to address misconceptions, engaging patients in management decisions, and using digital tools. Strategies to improve physician therapeutic inertia, such as reminders, education, physician-peer visits, and task-sharing may improve BP control rates. Digital health technologies, such as telemonitoring, wearables, and other mobile health platforms, are becoming frequently adopted tools in hypertension management, particularly those that have undergone regulatory approval. Finally, to fight the consequences of hypertension on a global scale, healthcare system approaches to cardiovascular risk factor management are needed. Government policies should promote routine BP screening, salt-, sugar-, and alcohol reduction programmes, encourage physical activity, and target obesity control.

Laboratory testing and antihypertensive medication adherence following initial treatment of incident, uncomplicated hypertension: A real-world data analysis

In this study on medication adherence among newly diagnosed patients with uncomplicated, incident hypertension, we conducted a retrospective cohort study using available administrative and laboratory data from April 1, 2012 to March 31, 2017 in Alberta, Canada to understand the extent to which baseline laboratory assessment and/or subsequent follow-up was associated with persistence with antihypertensive therapy. We determined the frequency of baseline and follow-up testing and compared the rates of medication persistence by patient-, neighbourhood-, and treatment-related factors. Of 103 232 patients with newly diagnosed, uncomplicated hypertension who filled their first prescription within our study timeframe, 52.5% were non-persistent within 6 months. Persistent patients were more often female and residing in neighbourhoods with higher social status (with exception to rurality). Aside from older age, the strongest predictor of persistence was performance of laboratory testing related to hypertension with an apparent effect in which higher levels of medication persistence were seen with more frequent laboratory testing. We concluded that medication persistence was far from optimal, dropping off considerably after 6 months for more than half of patients. Medication persistence is a substantial barrier to realizing the full societal benefits of antihypertensive treatment. Ongoing follow up with patients, including laboratory testing, may be a critical component of better long term treatment persistence.

Patient views on emergency department screening and interventions related to housing

Objectives Emergency departments (EDs) serve as a health care "safety net" and may be uniquely suited to screening for and addressing patients' unmet social needs. We aimed to better understand patient perspectives on ED-based screening and interventions related to housing instability, as a step toward improving future efforts. Methods We present findings from a qualitative study using in-depth, one-on-one interviews with ED patients who had become homeless in the past 6 months. Qualitative interviewees were asked their thoughts on ED staff asking about and helping to address homelessness and housing issues. Interviews were professionally transcribed verbatim. Multiple coders identified interview text segments focused on ED-based housing screening and intervention, which were then independently analyzed thematically and discussed to reach consensus. Researchers also categorized each participant's overall opinion on ED housing screening and interventions as positive, neutral, or negative. Results Qualitative interviews were conducted with 31 patients. Four themes related to ED-based housing screening and interventions emerged: (1) patients generally welcome ED staff/providers asking about and assisting with their housing situation, with caveats around privacy and respect; (2) ED conversations about housing have potential benefits beyond addressing unmet housing needs; (3) patients may not consider the ED as a site to obtain help with housing; (4) patients' experiences navigating existing housing services can inform best approaches for the ED. Most participants expressed overall positive views of ED staff/providers asking patients about their housing situation. Conclusions Study participants generally felt positively about screening and interventions for housing in the ED. Insights from this study can inform future ED-based housing instability screening and interventions.

Barriers to Follow Up Care in the South Asian Immigrant Population at High Risk of Acute Coronary Syndrome at Elmhurst Hospital Center

We studied South Asian immigrant patients who did not return to Elmhurst Hospital Center (EHC) after emergent cardiac catheterization in order to propose interventions to improve follow up care. We identified 74 eligible patients, interviewed 30 about follow up practices, and analyzed findings. Most patients are Bangladeshi and 77% preferred a foreign language. Some were visiting the US during the admission without intent to follow up. Half were dissatisfied with EHC providers, complications, and inadequate care at follow up appointments. Some patients were unaware of scheduled appointments or the necessity of follow up. Most follow with private providers due to language accessibility, availability, and proximity. We found that language barriers contribute to loss to follow up and the true loss to follow up rate is lower than reported at EHC. This can inform practices at hospitals with immigrant populations, minimize resource waste, and improve quality of care.

A Missed Opportunity? How Health Care Organizations Engage Primary Care Clinicians in Formal Social Care Efforts

Health care organizations increasingly recognize the impact of social needs on health outcomes. As organizations develop and scale efforts to address social needs, little is known about the optimal role for clinicians in providing social care. In this study, the authors aimed to understand how health care organizations involve clinicians in formal social care efforts. In 2019, the authors conducted 33 semi-structured interviews with administrators at 29 health care organizations. Interviews focused on the development and implementation of formal social care programs within the health care organization and the role of clinicians within those programs. A few administrators described formal roles for primary care clinicians in organizational efforts to deliver social care. Administrators frequently described programs that were deliberately structured to shield clinicians (eg, clinicians were not expected to review social risk screening results or be involved in addressing social needs). The authors identified 4 ways that administrators felt clinicians could meaningfully engage in social care programs: (1) discuss social risks to strengthen relationships with patients; (2) adjust clinical care follow-up plans based on social risks; (3) modify prescriptions based on social risks; and (4) refer patients to other care team members who can directly assist with social risks. Administrators were hesitant to increase primary care clinicians' responsibilities by tasking them with social care activities. Defining appropriate and scalable roles for clinicians along with adequate support from other care team members may increase the effectiveness of social care programs.

The Effect of Physician Immediacy on Patient Liking for Physician, Motivation, and Recall

Guided by the fostering relationships function of patient-centered communication (PCC), the present study utilized a 2 (high/low nonverbal immediacy) x 2 (high/low verbal immediacy) between-subjects experimental design to determine whether physician verbal and nonverbal immediacy influenced participant liking for physician, motivation to process a health message, and recall of the health message. An actor physician delivered a 3-4 minute video-recorded message, diagnosing U.S. adult participants, serving as analogue patients, with a health issue. The results indicated main effects for physician verbal immediacy and nonverbal immediacy on participant liking for physician and motivation such that participants had greater liking for the physician and motivation to do what the physician requested when the physician demonstrated greater verbal and nonverbal immediacy. However, physician verbal and nonverbal immediacy did not influence participants' recall. Physicians should consider displaying verbal and nonverbal immediacy to create a positive impression among patients, and to motivate patients to take steps to improve their health.

Barriers, Enablers and Strategies for the Treatment and Control of Hypertension in Nepal: A Systematic Review

Background: Understanding country-specific factors influencing hypertension care is critical to address the gaps in the management of hypertension. However, no systematic investigation of factors influencing hypertension treatment and control in Nepal is available. This study aimed to systematically review the published literature and synthesise the findings on barriers, enablers, and strategies for hypertension treatment and control in Nepal.

Methods: Embase, PubMed, Web of Science, CINAHL, ProQuest and WorldCat, and Nepali journals and government websites were searched for qualitative, quantitative, and mixed-methods studies on factors or strategies related to hypertension treatment and control in Nepal. Information from qualitative studies was analysed using template analysis, while results from quantitative studies were narratively synthesised. Summary findings were framed under “health system”, “provider”, and “patient” domains. The protocol was registered in PROSPERO (registration number: CRD42020145823).

Results: We identified 15 studies; ten related to barriers and enablers and five to strategies. The identified barriers associated with the health system were: lack of affordable services and lack of resources. The barriers at the provider's level were: communication gaps, inadequate counselling, long waiting hours for appointments, lack of national guidelines for hypertension treatment, and provider's unsupportive behaviours. Non-adherence to medication, irregular follow-up visits, lack of awareness on blood pressure target, poor help-seeking behaviours, reluctance to change behaviours, perceived side-effects of anti-hypertensive medication, self-medication, lack of family support, financial hardship, lack of awareness on blood pressure complications, and comorbidity were barriers identified at patient level. The following enablers were identified: free essential health care services, family support, positive illness perception, and drug reminders. Strategies implemented at the health system, provider and patient levels were: establishing digital health records at health centres, health worker's capacity development, and health education.

Conclusion: There is a range of barriers for hypertension treatment and control in Nepal pertaining to the health system, health providers, and patients. Comprehensive interventions are needed at all three levels to further improve management and control of hypertension in Nepal.

Measuring the multiple domains of medication nonadherence: findings from a Delphi survey of adherence experts

Consensus on a gold-standard measure of patient medication nonadherence has been elusive, in part because medication nonadherence involves multiple, distinct behaviors across three phases (initiation, implementation, and persistence). To assess these behaviors, multiple measurement approaches may be needed. The purpose of this study was to identify expert-recommended approaches to measuring nonadherence behaviors. Thirty medication nonadherence experts were e-mailed two consecutive surveys. In both, respondents rated their agreement with definitions of nonadherence behaviors and measurement approaches. In the second survey, respondents rated the suitability of each measurement approach for assessing each behavior and identified the optimal measurement approach for each behavior. Consensus was achieved for eight patient medication nonadherence behaviors: not filling initial prescription and not taking first dose (noninitiation); refilling prescription late, missing doses, taking extra doses, taking doses at wrong time, and improperly administering medication (incorrect implementation); and discontinuing medication early (nonpersistence). Consensus was achieved for seven measurement approaches: self-report, prescription fill data, pill count, drug levels, electronic drug monitoring (EDM), smart technology, and direct observation. Self-report questionnaires were most commonly rated "at least somewhat suitable" for measuring behaviors. EDM was rated as optimal for measuring missing doses, taking extra doses, and taking doses at the wrong time. Prescription fill data were rated as optimal for not filling initial prescription, refilling late, and discontinuing. Direct observation was rated as optimal for measuring improper administration. Suitable and optimal measurement approaches varied across nonadherence behaviors. Researchers should select the measurement approach best suited to assessing the behavior(s) targeted in their research.

Association Between Patient-Clinician Relationships and Adherence to Antihypertensive Medications Among Black Adults: An Observational Study Design

Background We assessed the associations between patient-clinician relationships (communication and involvement in shared decision-making [SDM]) and adherence to antihypertensive medications. Methods and Results The 2010 to 2017 Medical Expenditure Panel Survey (MEPS) data were analyzed. A retrospective cohort study design was used to create a cohort of prevalent and new users of antihypertensive medications. We defined constructs of patient-clinician communication and involvement in SDM from patient responses to the standard questionnaires about satisfaction and access to care during the first year of surveys. Verified self-reported medication refill information collected during the second year of surveys was used to calculate medication refill adherence; adherence was defined as medication refill adherence ≥80%. Survey-weighted multivariable-adjusted logistic regression models were used to measure the odds ratio (OR) and 95% CI for the association between both patient-clinician constructs and adherence. Our analysis involved 2571 Black adult patients with hypertension (mean age of 58 years; SD, 14 years) who were either persistent (n=1788) or new users (n=783) of antihypertensive medications. Forty-five percent (n=1145) and 43% (n=1016) of the sample reported having high levels of communication and involvement in SDM, respectively. High, versus low, patient-clinician communication (OR, 1.38; 95% CI, 1.14-1.67) and involvement in SDM (OR, 1.32; 95% CI, 1.08-1.61) were both associated with adherence to antihypertensives after adjusting for multiple covariates. These associations persisted among a subgroup of new users of antihypertensive medications. Conclusions Patient-clinician communication and involvement in SDM are important predictors of optimal adherence to antihypertensive medication and should be targeted for improving adherence among Black adults with hypertension.

Physician Communication in Injectable Opioid Agonist Treatment: Collecting Patient Ratings With the Communication Assessment Tool

OBJECTIVE

Patient ratings of physician communication in the setting of daily injectable opioid agonist treatment are reported. Associations between communication items and demographic, health, drug use, and treatment characteristics are explored.

METHODS

Participants (n = 121) were patients receiving treatment for opioid use disorder with hydromorphone (an opioid analgesic) or diacetylmorphine (medical grade heroin). Ratings of physician communication were collected using the 14-item Communication Assessment Tool. Items were dichotomized and associations were explored using univariate and multivariable logistic regression models for each of the 14 items.

RESULTS

Ratings of physician communication were lower than reported in other populations. In nearly all of the 14 multivariable models, participants with more physical health problems and with lower scores for treatment drug liking had lower odds of rating physician communication as excellent.

CONCLUSIONS

In physician interactions with patients with opioid use disorder, there is a critical need to address comorbid physical health problems and account for patient medication preferences.

PRACTICE IMPLICATIONS

Findings reinforce the role physicians can play in communicating with patients about their comorbid conditions and about medication preferences. In the patient-physician interaction efforts to meet patients' evolving treatment needs and preferences can be made by offering patients access to all available evidence-based treatments.

Assessing the relationship between patient-provider communication quality and quality of life among rural cancer survivors

PURPOSE

We explored relationships between patient-provider communication quality (PPCQ) and three quality of life (QOL) domains among self-identified rural cancer survivors: social well-being, functional well-being, and physical well-being. We hypothesized that high PPCQ would be associated with greater social and functional well-being, but be less associated with physical well-being, due to different theoretical mechanisms.

METHODS

All data were derived from the 2017-2018 Illinois Rural Cancer Assessment (IRCA). To measure PPCQ and QOL domains, we respectively used a dichotomous measure from the Medical Expenditure Panel Survey's Experience Cancer care tool (high, low/medium) and continuous measures from the Functional Assessment of Cancer Therapy-General (FACT-G).

RESULTS

Our sample of 139 participants was largely female, non-Hispanic White, married, and economically advantaged. After adjusting for demographic and clinical variables, patients who reported high PPCQ exhibited greater social well-being (Std. β = 0.20, 95% CI: 0.03, 0.35, p = 0.02) and functional well-being (Std. β = 0.20, 95% CI: 0.05, 0.35, p = 0.03) than patients with low/medium PPCQ. No association was observed between PPCQ and physical well-being (Std. β = 0.06, 95% CI: - 2.51, 0.21, p = 0.41). Sensitivity analyses found similar, albeit attenuated, patterns.

CONCLUSION

Our findings aligned with our hypotheses. Future researchers should explore potential mechanisms underlying these differential associations. Specifically, PPCQ may be associated with social and functional well-being through interpersonal mechanisms, but may not be as associated with physical well-being due to multiple contextual factor rural survivors disproportionately face (e.g., limited healthcare access, economic hardship) and stronger associations with clinical factors.

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.

Enhancing patients' understanding of and adherence to oral anticancer medication: Results of a longitudinal pilot intervention

BACKGROUND

Oral anticancer medications (OAM) make administration more convenient for patients, but shifts the responsibility of care from clinical providers to the patients themselves. Following an institutional pilot study showing inadequate understanding and adherence among vulnerable patients taking OAM, a longitudinal intervention was developed using an oncology specialty pharmacist and medication navigators to enhance OAM understanding and adherence.

METHODS

Patients initiating OAM were approached for four formalized teaching and check-in sessions, supplemented with medication information sheets and individualized calendars. At each session, participants were assessed on their OAM understanding and adherence using teach-back and validated measures. A study evaluation elicited feedback from participants on the usefulness of the intervention.

RESULTS

Of 80 eligible patients, 58 (72.5%) received formal OAM teaching from the specialty pharmacist. Of those, 54 (93.1%) enrolled in the study with 39 (72%) completing the intervention for final analysis. At study completion, all participants adequately understood OAM taking, but 41.0% had inadequate understanding of OAM handling. Throughout the study, participants reported issues that were addressed by the intervention team (28.2% to 31.6%) as well as those requiring additional assistance from the treatment team (26.3% to 38.5%), Most participants found the intervention to be very beneficial (initial evaluation, 86.5%; final evaluation, 76.9%).

CONCLUSIONS

This pilot intervention addressed gaps identified by our institutional assessment through formalized OAM teaching and follow-up. Improved understanding of taking and handling OAM through this subsequent study illustrated the enhanced effect of a multidisciplinary and multicomponent intervention to better educate and support patients on OAM.

Unmet social needs among low-income adults in the United States: Associations with health care access and quality

OBJECTIVE

To describe social needs among low-income adults and estimate the relationship between level of unmet social needs and key indicators of health care access and quality.

DATA SOURCE

National survey data from 12 states from the 2017 Behavioral Risk Factor Surveillance System, which added a "Social Determinants of Health" Module in 2017.

STUDY DESIGN

We examined differences in eight measures of health care access and quality (eg, check-up in last 12 months, inability to see doctor due to cost, receipt of eye examination for diabetics) for low-income adults with 0, 1, 2-3, and 4+ unmet social needs based on 7 social needs measures. We used adjusted logistic regression models to estimate the association between level of unmet need and each outcome.

PRINCIPAL FINDINGS

Most common unmet social needs included not having enough money for balanced meals (33 percent) or food (32 percent). After adjusting for observable characteristics, higher levels of unmet social need were associated with poorer access and quality. Compared to those with no reported unmet needs, having 4+ unmet needs was significantly associated with reduced probability of having a yearly check-up (65 percent vs 78 percent, adjusted difference = -7.1 percentage points (PP)), receiving a flu vaccine (33 percent vs 42 percent, adjusted difference = -5.4 PP), having a personal doctor (74 percent vs 80 percent, adjusted difference = -3.1 PP), and having a foot (63 percent vs 80 percent, adjusted difference = -12.8 PP) or eye examination (61 percent vs 73 percent, adjusted difference = -12.6 PP) for diabetic patients, and increased probability of being unable to see a doctor due to cost (44 percent vs 9 percent, adjusted difference = 27.9 PP) and having diabetes affect the eyes (22 percent vs 19 percent, adjusted difference = 8.0 PP) at α = 0.05.

CONCLUSIONS

Higher levels of unmet social needs were associated with poorer access to and quality of care among low-income adults. Addressing social needs both inside and outside of health care settings may help mitigate these negative effects. Additional research on if and how to effectively do so is critical.

Adherence to Antihypertensive Medication: An Interview Analysis of Southwest Ugandan Patients' Perspectives

Background:

Hypertension is a significant cardiovascular disease (CVD) and driver to CVD disorders in sub-Saharan Africa. It is a major independent risk factor for heart failure, stroke, and kidney failure. Persons living with hypertension attend to many aspects of self-care to manage their condition, including high blood pressure medication adherence to control of blood pressure. Rates of medication non-adherence, and thus uncontrolled hypertension, remain high and contribute to poor health outcomes. Understanding barriers and facilitators to adherence to hypertension therapies can help improve health outcomes.

Objective:

The aim of the study was to describe the common reasons for adherence and non-adherence to antihypertensive medication from patients’ perspectives.

Methods:

A qualitative study engaged clients of an out-patient clinic of a regional referral hospital in southwestern Uganda who were living with hypertension as participants. One-on-one in-depth interviews provided the narrative data. The interview transcripts were analyzed using thematic analysis.

Findings:

Sixteen participants provided the data for the findings. The themes identified as facilitators for adherence to antihypertensive medication were patients’ understanding of prescribed medication, availability of medication for hypertension, family support for patients living with hypertension, and regular review appointments at the hypertensive clinics. Conversely, lack of supply in government dispensaries, use of self-prescribed analgesic medication, and stigma were identified as barriers and challenges of adherence to antihypertensive medication.

Conclusions:

There is an urgent need for the health ministry to improve availability of high blood pressure medication and for health care providers to deliver individualized patient centered care, and sensitization on danger of self-prescription and measures that reduce stigma. These strategies may improve adherence to high blood pressure medication.

Understanding the Traditional Chinese Medicine (TCM) consultation: Why do patients adhere to treatment?

BACKGROUND

and purpose: Adherence is an issue that affects Complementary and Alternative Medicine (CAM) and conventional medicine practitioners, whereby approximately half of the patients do not take their medicines or remedies as prescribed. The consultation is an opportune area where practitioners can have an impact on patient adherence to treatment. As such, research was undertaken to explore this in depth within one CAM. The aim of the study was to understand the Traditional Chinese Medicine (TCM) consultation process that occurs in relation to adherence and develop a consultation model health professionals can use.

MATERIALS AND METHODS

A classical grounded theory approach was employed to semi-structured interviews of TCM practitioners and patients along with observations of their consultations. Sampling was theoretical and by snowball in the United Kingdom. NVivo 11 was used to assist with analysis of the transcribed interviews and observations.

RESULTS

Seven TCM practitioners and twenty-eight patients were recruited. TCM practitioners built a therapeutic relationship through the consultation by enabling patients to feel comfortable, valued as individuals which incorporated feeling understood and known, as well as supported in the management of their health. Fundamentally, patients needed to feel cared for and have trust in their TCM practitioner for the therapeutic relationship to be established. This motivated patients to continue with treatment.

CONCLUSION

The TCM Consultation Model for Adherence was developed to conceptualise the consultation process that occurs in relation to adherence. It can be used to encourage patient persistence with treatment by TCM practitioners and potentially other health professionals.

Adherence to antihypertensive fixed-dose combination among Egyptian patients presenting with essential hypertension

Background

Many patients with hypertension require more than one drug to achieve blood pressure control. They are prescribed with fixed-dose combination (FDC) antihypertensive therapy rather than monotherapies. Although it is commonly admitted that the use of FDC may improve compliance to treatment, adherence rates in patients receiving FDCs have not been documented. Therefore, the aim of this study was to assess the adherence to treatment in patients receiving FDCs of antihypertensive medications in a real-world setting in Egypt.

Results

We conducted a multi-center cross-sectional study over a period of 1 year from Jan 2017 to Jan 2018. We included patients above 21 years old with essential hypertension who were already prescribed with an FDC of antihypertensive treatment for at least 3-month duration. We assessed the adherence to treatment by patient self-assessment using the Morisky 8-Item Medication Adherence Scale (MMAS 8).

This study enrolled 2000 hypertensive Egyptian patients. The mean age of enrolled patients was 55.8 ± 10.9 years. Male to female ratio was 1.08. The mean MMAS score was 6.5 ± 1.9. Our analysis showed that 825 (41.3%) patients reached high adherence score, 523 (26.2%) medium adherence, and 652 (32.6%) low adherence.

Furthermore, Male patients showed higher adherence rate than females (56.4% versus 43.6%, p < 0.001). Out of 746 patients with controlled blood pressure (< 140/90), 387 (51.9%) patients were highly adherent to treatment. Higher level of education was significantly associated with high adherence rate; 559 (67.8%) patients were university graduates, 232 (28.1%) had primary/secondary school education, and 34 (4.1%) were illiterate (p < 0.001).

Moreover, once daily (99.2%) fixed-dose combination was associated with higher adherence rate than twice regimen daily (0.8%), p = 0.03. Multivariate logistic regression analysis showed that patients with high level of education, employed patients, and patients with controlled blood pressure have high adherence rate to medication.

Conclusions

Higher adherence to medication is associated with high level of education and employment, and it can lead to better blood pressure control. Thus, patient education programs may increase patients’ adherence to their medication.

Patients' perspectives of tuberculosis treatment challenges and barriers to treatment adherence in Ukraine: a qualitative study

OBJECTIVES

To understand the challenges faced by patients with tuberculosis (TB) and factors that influence TB treatment adherence in Ukraine.

DESIGN

Qualitative study.

SETTING

TB treatment facilities in Kyiv Oblast, Ukraine.

PARTICIPANTS

Sixty adults who had undergone treatment for drug-sensitive TB between June 2012 and August 2015.

METHODS

We conducted semistructured, in-depth, individual interviews among a purposively selected clinical sample of patients previously treated for drug-sensitive TB. Interview content encompassed WHO's framework for barriers to adherence to long-term therapies and included questions about patient preferences and motivators concerning treatment adherence. We examined treatment experience across strata defined by previously identified risk correlates of non-adherence.

RESULTS

Among 60 participants, 19 (32.8%) were HIV positive, 12 (20.3%) had substance use disorder and 9 (15.0%) had not completed TB treatment. Respondents discussed the psychological distress associated with hospital-based TB care, as well as perceived unsupportive, antagonistic interactions with TB providers as major challenges to treatment adherence. An additional barrier to successful treatment completion included the financial toll of lost income during TB treatment, which was exacerbated by the additional costs of ancillary medications and transportation to ambulatory TB clinics. The high pill burden of TB treatment also undermined adherence. These challenges were endorsed among participants with and without major risk factors for non-adherence.

CONCLUSIONS

Our findings highlight important barriers to TB treatment adherence in this study population and suggest specific interventions that may be beneficial in mitigating high rates of poor treatment outcomes for TB in Ukraine.

Challenges and strategies for hypertension management: qualitative analysis of small primary care practices with varying blood pressure control

BACKGROUND

Electronic health record (EHR) data on blood pressure (BP) control among patients with hypertension show that practices' rates vary greatly. This suggests providers use different approaches in managing hypertension, and so we aimed to explore challenges small primary care practice providers face and strategies they use to manage patients' BP. We explored differences between providers with high and low BP control rates to help inform future quality improvement work.

METHODS

In 2015, we recruited practices in New York City with five or fewer providers. We employed a stratified purposeful sampling method, using EHR data to categorize small practices into groups based on the proportion of patients with hypertension whose last BP was <140/90: high control (>= 80%), average control (60-80%) and low control (<60%). We conducted semi-structured qualitative interviews with clinicians from 23 practices-7 high control, 10 average control and 6 low control-regarding hypertension management. We used a combined inductive/deductive approach to identify key themes, and these themes guided a comparison of high and low BP control providers.

RESULTS

Small practice providers reported treatment non-adherence as one of the primary challenges in managing patients' hypertension, and described using patient education, relationship building and self-management tools to address this issue. Providers differed qualitatively in the way they described using these strategies; high BP control providers described more actively engaging and listening to patients than low control providers did.

CONCLUSIONS

How providers communicate with patients may impact outcomes-future quality improvement initiatives should consider trainings to improve patient-provider communication.

Patients' and caregivers' perspectives on factors that influence understanding of and adherence to hospital discharge instructions: a qualitative study

BACKGROUND

Many patients have difficulty understanding and adhering to discharge instructions once home from hospital. We assessed patient and family caregiver perspectives on factors that influence understanding of and adherence to discharge instructions.

METHODS

We conducted a qualitative study using semistructured interviews of participants aged 18 years or more enrolled in a multicentre mixed-methods study who were discharged from 3 acute care hospitals across Ontario with a diagnosis of congestive heart failure, chronic obstructive pulmonary disease or pneumonia. Patients were recruited between March and November 2016. We used directed content analysis to derive themes and subthemes.

RESULTS

Twenty-seven participants (16 patients and 11 family members) described 5 themes that affected their understanding of and adherence to discharge instructions: 1) the role of caregivers, 2) relationships with inpatient and outpatient health care providers, 3) previous hospital stay, 4) barriers to accessing postdischarge care and 5) system-level processes. Subthemes highlighted the importance participants attributed to who provides the instructions, the development of resilience and advocacy through previous admissions, the benefits of addressing language and physical disability barriers, reviewing instructions in a unhurried manner, and ensuring that written instructions are meaningful and actionable.

INTERPRETATION

Care transition interventions targeting improved communication are unlikely to improve understanding of and adherence to discharge instructions on their own. A patient-centred framework that promotes positive relationships with a patient's circle of care, reflects previous experiences with discharge, addresses equity barriers, and enhances strategies for patient and caregiver engagement at the time of discharge may optimize understanding and adherence once the patient is home.

It takes two to tango: A dyadic approach to understanding the medication dialogue in patient-provider relationships

OBJECTIVE

To describe typologies of dyadic communication exchanges between primary care providers and their hypertensive patients about prescribed antihypertensive medications.

METHODS

Qualitative analysis of 94 audiotaped patient-provider encounters, using grounded theory methodology.

RESULTS

Four types of dyadic exchanges were identified: Interactive (53% of interactions), divergent-traditional (24% of interactions), convergent-traditional (17% of interactions) and disconnected (6% of interactions). In the interactive and convergent-traditional types, providers adopted a patient-centered approach and used communication behaviors to engage patients in the relationship. Patients in these interactions adopted either an active role in the visit (interactive), or a passive role (convergent-traditional). The divergent-traditional type was characterized by provider verbal dominance, which inhibited patients' ability to ask questions, seek information, or check understanding of information. In the disconnected types, providers used mainly closed-ended questions and terse directives to gather and convey information, which was often disregarded by patients who instead diverted the conversation to psychosocial issues.

CONCLUSIONS

This study identified interdependent patient-provider communication styles that can either facilitate or hinder discussions about prescribed medications.

PRACTICE IMPLICATIONS

Examining the processes that underlie dyadic communication in patient-provider interactions is an essential first step to developing interventions that can improve the patient-provider relationship and patient health behaviors.

The nature and scope of patient-sharing network research: a novel, important area for network science

A robust literature exists that draws on social network approaches to understand connections among individuals, and healthcare and behavior-related implications. This article offers commentary on the scoping review conducted by Dugoff et al. that examines "patient-sharing" networks, their characteristics, and various methodological approaches. The scoping review conducted by Dugoff et al. examines the characteristics and methods employed in patient-sharing network studies. It identified the most common measures used in patient-sharing network research, as well as theories used in patient-sharing network studies. Dugoff et al. also identified many studies that examined healthcare utilization considerations for patient sharing. Understanding the connections between providers and the flow of patients between providers could lend insight into barriers and enablers to efficient healthcare systems.

Community Outreach to African-Americans: Implementations for Controlling Hypertension

PURPOSE OF REVIEW

The purpose of this review is to examine the impact and effectiveness of community interventions for controlling hypertension in African-Americans. The questions addressed are as follows: Which salient prior and current community efforts focus on African-Americans and are most effective in controlling hypertension and patient-related outcomes? How are these efforts implemented and possibly sustained?

RECENT FINDINGS

The integration of out-of-office blood pressure measurements, novel hypertension control centers (i.e., barbershops), and community health workers improve hypertension control and may reduce the excess hypertension-related complications in African-Americans. Several community-based interventions may assist effectiveness of clinical care teams, decrease care barriers, and improve adherence. A multifaceted, tailored, multidisciplinary community-based approach may effectively reduce barriers to blood pressure control among African-Americans. Future research should evaluate the long-term benefits of community health workers, barbershops as control centers, and out-of-office blood pressure monitoring upon control and eventually on morbidity and mortality.

Treatment adherence among adult hypertensive patients: a cross-sectional retrospective study in primary care in Romania

PURPOSE

This study was performed to elucidate the level of adherence to antihypertensive treatment in adult subjects attending a family medicine clinic in a city in central Romania.

PATIENTS AND METHODS

A cross-sectional, retrospective study was performed on a cohort of hypertensive adults. A total of 525 participants were selected from 1,714 adults attending a single urban family medicine practice. Assessment of adherence to therapy was performed by a chart review of prescription and clinical records over a 4-year study period.

RESULTS

The results showed that 69.8% of the patients had high adherence (>80% with therapy); 20.3% had medium adherence (20%-79%); and 9.9% had low adherence (<20%). A positive association was found (p = 0.01) between low adherence and male gender. A significant positive association (p = 0.02) was found between total cardiovascular risk and level of adherence. We found that 54.7% of the high adherence subjects had well-controlled blood pressure, and chronic kidney disease was associated with high adherence to therapy (p = 0.03). Antihypertensive regimens administered as fixed-dose combinations were positively associated with high adherence (p = 0.001). Subjects who had their antihypertensive regimen adjusted to a new drug class during the study period showed enhanced adherence compared to subjects treated with an unchanged regimen (p = 0.001).

CONCLUSION

This is the first published study assessing adherence to antihypertensive therapy in family medicine practice in Romania. It presented data derived from a primarily urban setting and targeted a geographical area where the prevalence of hypertension has increased continuously. Female gender, age, presence of cardiovascular risk factors, defined cardiovascular disease, chronic renal impairment, and good control of hypertension were positively associated with high adherence. The results provide insights to guide further strategies to improve adherence and indirect methods for blood pressure management strategies.
