Hypertension Self-management in Socially Disadvantaged African Americans: the Achieving Blood Pressure Control Together (ACT) Randomized Comparative Effectiveness Trial.

BACKGROUND: Effective hypertension self-management interventions are needed for socially disadvantaged African Americans, who have poorer blood pressure (BP) control compared to others. OBJECTIVE: We studied the incremental effectiveness of contextually adapted hypertension self-management interventions among socially disadvantaged African Americans. DESIGN: Randomized comparative effectiveness trial. PARTICIPANTS: One hundred fifty-nine African Americans at an urban primary care clinic. INTERVENTIONS: Participants were randomly assigned to receive (1) a community health worker ("CHW") intervention, including the provision of a home BP monitor; (2) the CHW plus additional training in shared decision-making skills ("DoMyPART"); or (3) the CHW plus additional training in self-management problem-solving ("Problem Solving"). MAIN MEASURES: We assessed group differences in BP control (systolic BP (SBP) < 140 mm Hg and diastolic BP (DBP) < 90 mmHg), over 12 months using generalized linear mixed models. We also assessed changes in SBP and DBP and participants' BP self-monitoring frequency, clinic visit patient-centeredness (i.e., extent of patient-physician discussions focused on patient emotional and psychosocial concerns), hypertension self-management behaviors, and self-efficacy. KEY RESULTS: BP control improved in all groups from baseline (36%) to 12 months (52%) with significant declines in SBP (estimated mean [95% CI] - 9.1 [- 15.1, - 3.1], - 7.4 [- 13.4, - 1.4], and - 11.3 [- 17.2, - 5.3] mmHg) and DBP (- 4.8 [- 8.3, - 1.3], - 4.0 [- 7.5, - 0.5], and - 5.4 [- 8.8, - 1.9] mmHg) for CHW, DoMyPART, and Problem Solving, respectively). There were no group differences in BP outcomes, BP self-monitor use, or clinic visit patient-centeredness. The Problem Solving group had higher odds of high hypertension self-care behaviors (OR [95% CI] 18.7 [4.0, 87.3]) and self-efficacy scores (OR [95% CI] 4.7 [1.5, 14.9]) at 12 months compared to baseline, while other groups did not. Compared to DoMyPART, the Problem Solving group had higher odds of high hypertension self-care behaviors (OR [95% CI] 5.7 [1.3, 25.5]) at 12 months. CONCLUSION: A context-adapted CHW intervention was correlated with improvements in BP control among socially disadvantaged African Americans. However, it is not clear whether improvements were the result of this intervention. Neither the addition of shared decision-making nor problem-solving self-management training to the CHW intervention further improved BP control.

Promoting sustainability in quality improvement: an evaluation of a web-based continuing education program in blood pressure measurement.

BACKGROUND: The accuracy of blood pressure measurement is variable in office-based settings. Even when staff training programs are effective, knowledge and skills decay over time, supporting the need for ongoing staff training. We evaluated whether a web-based continuing education program in blood pressure measurement reinforced knowledge and skills among clinical staff and promoted sustainability of an existing quality improvement program. METHODS: Medical assistants and nurses at six primary care clinics within a health system enrolled in a 30-min online educational program designed to refresh their knowledge of blood pressure measurement. A 20-question pre- and post-intervention survey addressed learners' knowledge and attitudes. Direct observation of blood pressure measurement technique before and after the intervention was performed. Differences in responses to pre- and post-module knowledge and attitudes questions and in observation data were analyzed using chi-square tests and simple logistic regression. RESULTS: All 88 clinical staff members participated in the program and completed the evaluation survey. Participants answered 80.6% of questions correctly before the module and 93.4% afterwards (p < 0.01). Scores improved significantly among staff from all job types. Licensed practical nurses and staff who had been in their current job at least a year were more likely to answer questions correctly than registered nurses and those in their current job less than a year. Attitudes toward correct blood pressure measurement were high at baseline and did not improve significantly. Prior to the intervention, staff adhered to 9 of 18 elements of the recommended technique during at least 90% of observations. Following the program, staff was more likely to explain the protocol, provide a rest period, measure an average blood pressure, and record the average blood pressure, but less likely to measure blood pressure with the arm at heart level and use the right arm. CONCLUSIONS: We designed, implemented, and evaluated a web-based educational program to improve knowledge, skills, and attitudes in blood pressure measurement and use of an automated device among nurses and medical assistants in ambulatory care. The program reinforced knowledge related to recommended blood pressure measurement technique.

Adapting hypertension self-management interventions to enhance their sustained effectiveness among urban African Americans.

African Americans suffer disproportionately poor hypertension control despite the availability of efficacious interventions. Using principles of community-based participatory research and implementation science, we adapted established hypertension self-management interventions to enhance interventions' cultural relevance and potential for sustained effectiveness among urban African Americans. We obtained input from patients and their family members, their health care providers, and community members. The process required substantial time and resources, and the adapted interventions will be tested in a randomized controlled trial.

Primary Care Utilization, Preventative Screening, and Control of Metabolic Syndrome in Metabolic Dysfunction-Associated Steatohepatitis Liver Transplant Recipients.

OBJECTIVES: Patients with pre-transplant metabolic dysfunction-associated steatohepatitis (MASH) are at high risk of metabolic syndrome (MetS) after liver transplant. While many patients are co-managed by a transplant team, most preventative screening and MetS management may occur in the primary care setting. We aimed to evaluate primary care utilization by MASH liver transplant recipients as well as MetS screening and control. METHODS: We conducted a retrospective chart review that included adults who underwent liver transplant for MASH or cryptogenic cirrhosis at a single institution from January 2010 to December 2016, had available primary care data, and at least 36-months of follow-up post-transplant. Measures included primary care utilization, adherence to screening guidelines, and control of MetS. We used Fischer's exact test to explore the association of primary care utilization with screening and control. RESULTS: A total of 37 patients met inclusion criteria with 366 visits reviewed. The median time to first visit was 68 days post-transplant and patients had a median of 9 total visits. Few patients met screening guidelines for diabetes (8.1%) or hyperlipidemia (10.8%). The percentage of patients with control of obesity, hypertension, diabetes, and hyperlipidemia decreased over the 36-month follow-up period. Primary care utilization was not associated with adherence to screening recommendations for diabetes (P = .141) or hyperlipidemia (P = .103). Higher primary care utilization was not associated with control of hypertension (P = .107), diabetes (P = .871), or hyperlipidemia (P = .999). CONCLUSION: More research is needed to investigate barriers to screening and management of MetS conditions in this high-risk patient population in the primary care setting as well as to optimize post-transplant care coordination.

Across race, ethnicity, and language: An intervention to improve advance care planning documentation unmasks health disparities.

BACKGROUND: Racial and ethnic minority groups are less likely to have advance directives and living wills, despite the importance of advanced care planning (ACP) in end-of-life care. We aimed to understand the impact of an intervention to improve ACP documentation across race, ethnicity, and language on hospitalized patients at our institution. METHODS: We launched an intervention to improve the rates of ACP documentation for hospitalized patients aged >75 or with advanced illness defined by the International Classification of Diseases 10th Revision codes. We analyzed ACP completion rates, preintervention, and intervention, and used interrupted time-series analyses to measure the differential impact of the intervention across race, ethnicity, and language. KEY RESULTS: A total of 10,220 patients met the inclusion criteria. Overall rates of ACP documentation improved from 13.9% to 43.7% in the intervention period, with a 2.47% monthly increase in ACP documentation compared to baseline (p < .001). During the intervention period, the rate of ACP documentation increased by 2.72% per month for non-Hispanic White patients (p < .001), by 1.84% per month for Latinx patients (p < .001), and by 1.9% per month for Black patients (p < .001). Differences in the intervention trends between non-Hispanic White and Latinx patients (p = .04) and Black patients (p = .04) were significant. CONCLUSIONS: An intervention designed to improve ACP documentation in hospitalized patients widened a disparity across race and ethnicity with Latinx and Black patients having lower rates of improvement. Our findings reinforce the need to measure the impact of quality improvement interventions on existing health disparities and to implement specific strategies to prevent worsening disparities.

A bundled quality improvement program to standardize clinical blood pressure measurement in primary care.

We evaluated use of a program to improve blood pressure measurement at 6 primary care clinics over a 6-month period. The program consisted of automated devices, clinical training, and support for systems change. Unannounced audits and electronic medical records provided evaluation data. Clinics used devices in 81.0% of encounters and used them as intended in 71.6% of encounters, but implementation fidelity varied. Intervention site systolic and diastolic blood pressure with terminal digit "0" decreased from 32.1% and 33.7% to 11.1% and 11.3%, respectively. Improvement occurred uniformly, regardless of sites' adherence to the measurement protocol. Providers rechecked blood pressure measurements less often post-intervention (from 23.5% to 8.1% of visits overall). Providers at sites with high protocol adherence were less likely to recheck measurements than those at low adherence sites. Comparison sites exhibited no change in terminal digit preference or repeat measurements. This study demonstrates that clinics can apply a pragmatic intervention to improve blood pressure measurement. Additional refinement may improve implementation fidelity.

Improving urban African Americans' blood pressure control through multi-level interventions in the Achieving Blood Pressure Control Together (ACT) study: a randomized clinical trial.

BACKGROUND: Given their high rates of uncontrolled blood pressure, urban African Americans comprise a particularly vulnerable subgroup of persons with hypertension. Substantial evidence has demonstrated the important role of family and community support in improving patients' management of a variety of chronic illnesses. However, studies of multi-level interventions designed specifically to improve urban African American patients' blood pressure self-management by simultaneously leveraging patient, family, and community strengths are lacking. METHODS/DESIGN: We report the protocol of the Achieving Blood Pressure Control Together (ACT) study, a randomized controlled trial designed to study the effectiveness of interventions that engage patient, family, and community-level resources to facilitate urban African American hypertensive patients' improved hypertension self-management and subsequent hypertension control. African American patients with uncontrolled hypertension receiving health care in an urban primary care clinic will be randomly assigned to receive 1) an educational intervention led by a community health worker alone, 2) the community health worker intervention plus a patient and family communication activation intervention, or 3) the community health worker intervention plus a problem-solving intervention. All participants enrolled in the study will receive and be trained to use a digital home blood pressure machine. The primary outcome of the randomized controlled trial will be patients' blood pressure control at 12months. DISCUSSION: Results from the ACT study will provide needed evidence on the effectiveness of comprehensive multi-level interventions to improve urban African American patients' hypertension control.

A multi-level system quality improvement intervention to reduce racial disparities in hypertension care and control: study protocol.

BACKGROUND: Racial disparities in blood pressure control have been well documented in the United States. Research suggests that many factors contribute to this disparity, including barriers to care at patient, clinician, healthcare system, and community levels. To date, few interventions aimed at reducing hypertension disparities have addressed factors at all of these levels. This paper describes the design of Project ReD CHiP (Reducing Disparities and Controlling Hypertension in Primary Care), a multi-level system quality improvement project. By intervening on multiple levels, this project aims to reduce disparities in blood pressure control and improve guideline concordant hypertension care. METHODS: Using a pragmatic trial design, we are implementing three complementary multi-level interventions designed to improve blood pressure measurement, provide patient care management services and offer expanded provider education resources in six primary care clinics in Baltimore, Maryland. We are staggering the introduction of the interventions and will use Statistical Process Control (SPC) charting to determine if there are changes in outcomes at each clinic after implementation of each intervention. The main hypothesis is that each intervention will have an additive effect on improvements in guideline concordant care and reductions in hypertension disparities, but the combination of all three interventions will result in the greatest impact, followed by blood pressure measurement with care management support, blood pressure measurement with provider education, and blood pressure measurement only. This study also examines how organizational functioning and cultural competence affect the success of the interventions. DISCUSSION: As a quality improvement project, Project ReD CHiP employs a novel study design that specifically targets multi-level factors known to contribute to hypertension disparities. To facilitate its implementation and improve its sustainability, we have incorporated stakeholder input and tailored components of the interventions to meet the specific needs of the involved clinics and communities. Results from this study will provide knowledge about how integrated multi-level interventions can improve hypertension care and reduce disparities.

Facilitators and barriers to hypertension self-management in urban African Americans: perspectives of patients and family members.

INTRODUCTION: We aimed to inform the design of behavioral interventions by identifying patients' and their family members' perceived facilitators and barriers to hypertension self-management. MATERIALS AND METHODS: We conducted focus groups of African American patients with hypertension and their family members to elicit their views about factors influencing patients' hypertension self-management. We recruited African American patients with hypertension (n = 18) and their family members (n = 12) from an urban, community-based clinical practice in Baltimore, Maryland. We conducted four separate 90-minute focus groups among patients with controlled (one group) and uncontrolled (one group) hypertension, as well as their family members (two groups). Trained moderators used open-ended questions to assess participants' perceptions regarding patient, family, clinic, and community-level factors influencing patients' effective hypertension self-management. RESULTS: Patient participants identified several facilitators (including family members' support and positive relationships with doctors) and barriers (including competing health priorities, lack of knowledge about hypertension, and poor access to community resources) that influence their hypertension self-management. Family members also identified several facilitators (including their participation in patients' doctor's visits and discussions with patients' doctors outside of visits) and barriers (including their own limited health knowledge and patients' lack of motivation to sustain hypertension self-management behaviors) that affect their efforts to support patients' hypertension self-management. CONCLUSION: African American patients with hypertension and their family members reported numerous patient, family, clinic, and community-level facilitators and barriers to patients' hypertension self-management. Patients' and their family members' views may help guide efforts to tailor behavioral interventions designed to improve hypertension self-management behaviors and hypertension control in minority populations.

Electrophysiologic and phenotypic features of an autosomal cone-rod dystrophy caused by a novel CRX mutation.

PURPOSE: To reexamine a large Albertan family previously reported with a progressive cone dystrophy with variable phenotype and to map the disorder using molecular genetic techniques. DESIGN: Observational case series. PARTICIPANTS: Twenty-nine subjects (10 affected) from four generations of a large kindred were clinically examined. Twenty-three of these individuals, as well as two unaffected spouses, were included in the molecular genetic study. Subject ages ranged from 17 to 91 years of age. METHODS: Disease status and associated ocular abnormalities were assessed primarily by measurement of visual acuity, color vision, fundus photography, and both full-field and multifocal electroretinography (ERG and mfERG). Linkage of the disorder to the rhodopsin gene was studied using microsatellites. A mutational screen of the CRX gene was performed to identify coding sequence changes. MAIN OUTCOME MEASURES: Visual acuity and color discrimination were reduced in clinically affected individuals; full-field flash ERG was used to measure function of both cones and rods. mfERG and fundus photography allowed documentation of the observed macular changes. RESULTS: We noted a variable, adult-onset macular dystrophy, progressing in some cases to a retinitis pigmentosa-like phenotype. Both photopic and scotopic full-field ERG amplitudes were reduced by approximately 50%, demonstrating involvement of both photoreceptor systems. A reduced b-wave amplitude with a relatively preserved a-wave was observed at both cone and rod levels. Macular involvement was confirmed by mfERG. The rhodopsin locus was excluded by haplotype analysis. A novel frameshift mutation was detected in exon III of the CRX retinal homeobox gene. ERG and molecular genetic findings were consistent with the reclassification of this disease as an autosomal dominant cone-rod dystrophy (CRD) CONCLUSIONS: We report a novel CRX mutation causing autosomal dominant CRD. Observed ERG changes suggest that this mutation primarily impairs inner retinal function. Because retinal expression of CRX is limited to photoreceptors, this dysfunction may be the result of faulty photoreceptor communication with second-order retinal neurons. We propose misexpression of gated cation channels caused by altered CRX activity as one putative mechanism by which a sole photoreceptor defect may selectively impair neurotransmission without disrupting the upstream events of phototransduction.
