COACH trial: a randomized controlled trial of nurse practitioner/community health worker cardiovascular disease risk reduction in urban community health centers: rationale and design

Task-sharing with community health workers to treat hypertension: a scoping review

Many studies have implemented and evaluated task-sharing interventions with community health workers (CHWs) to manage hypertension. To identify gaps in research, we conducted a scoping review. We searched original articles published in PubMed and EMBASE between 2010 and 2022 and found 122 articles meeting our inclusion criteria. Only seven articles were from low-income countries (LICs), most of which were qualitative studies or mixed methods studies. In the identified 122 articles, CHWs often performed health education (61.3%) and measured blood pressure (60.4%). Whereas CHWs carried out pharmacological treatment in only three studies. Participant homes (75.0%) were the most common setting for receiving interventions. Our study identified specific needs for future research, specifically, studies in LICs that are experimental in design and that collect relevant qualitative information, and studies in which CHWs do advanced task. In addition, publications of CHW studies should provide a more comprehensive list of intervention features.

Randomised pilot study comparing a coach to SMARTPhone reminders to aid the management of heart failure (HF) patients: humans or machines

Ambulatory management of congestive heart failure (HF) continues to be a challenging clinical problem. Recent studies have focused on the role of HF clinics, nurse practitioners and disease management programmes to reduce HF readmissions. This pilot study is a pragmatic factorial study comparing a coach intervention, a SMARTPHONE REMINDER system intervention and BOTH interventions combined to Treatment as USUAL (TAU). We determined that both modalities were acceptable to patients prior to randomisation. Fifty-four patients were randomised to the four groups. The COACH group had no readmissions for HF 6 months after enrolment compared with 18% for the SMARTPHONE REMINDER Group, 8% for the BOTH intervention group and 13% for TAU. Medium-to-high medication adherence was maintained in all four groups although sodium consumption was lower at 3 months for the COACH and combined (BOTH) groups. This pilot study suggests a beneficial effect on rehospitalisation with the use of support measures including coaches and telephone reminders that needs confirmation in a larger trial.

Establishing a multi-specialty consensus in the clinical need for hypercholesterolemia management and its implication for patients access to innovative therapies

BACKGROUND

Increased level of blood LDL-C has a causal and cumulative effect on advancing atherosclerotic cardiovascular diseases (ASCVD). European guidelines for treating high LDL-C levels have been recently updated. However, in France, several challenges (e.g., physician and patient awareness, healthcare management) limit the application of management guidelines. The aim of this study was to understand the current opinions and perceived unmet clinical needs in recognising and managing hypercholesterolemia as an ASCVD risk factor, and to explore consensus around factors that support the effective management of elevated LDL-C.

METHODS

An expert group of cardiologists, endocrinologists, biology/genetics researchers, and a health technology assessments expert, from France was convened. The current management of hypercholesterolemia and barriers to achieving LDL-C goals in France were discussed and 44 statements were developed. Wider consensus was assessed by sending the statements as a 4-point Likert Scale questionnaire to cardiologists and endocrinologists across France. The consensus threshold was defined as ≥75%.

RESULTS

A total of 101 responses were received. Consensus was very high (>90%) in 25 (57%) statements, high (≥75%) in 18 (41%) statements and was not achieved (<75%) only in 1 (2%) of statements. Overall, 43 statements achieved consensus.

CONCLUSIONS

Based on consensus levels, key recommendations for improving current guidelines and approaches to care have been developed. Implementation of these recommendations will lead to better concordance with international treatment guidelines and increase levels of education for healthcare practitioners and patients. In turn, this will improve the available treatment pathways for cardiovascular diseases, potentially creating improved patient outcomes in the future.

Cardiovascular Disease Risk in Rural Adults

BACKGROUND

Cardiovascular disease (CVD) risk reduction programs led by a nurse/community health worker team are effective in urban settings. This strategy has not been adequately tested in rural settings.

OBJECTIVE

A pilot study was conducted to examine the feasibility of implementing an evidence-based CVD risk reduction intervention adapted to a rural setting and evaluate the potential impact on CVD risk factors and health behaviors.

METHODS

A 2-group, experimental, repeated-measures design was used; participants were randomized to a standard primary care group (n = 30) or an intervention group (n = 30) where a registered nurse/community health worker team delivered self-management strategies in person, by phone, or by videoconferencing. Outcomes were measured at baseline and at 3 and 6 months. A sample of 60 participants was recruited and retained in the study.

RESULTS

In-person (46.3%) and telephone (42.3%) meetings were used more than the videoconferencing application (9%). Mean change at 3 months differed significantly between the intervention and control groups for CVD risk (-1.0 [95% confidence interval (CI), -3.1 to 1.1] vs +1.4 [95% CI, -0.4 to 3.3], respectively), total cholesterol (-13.2 [95% CI, -32.1 to 5.7.] vs +21.0 [95% CI, 4.1-38.1], respectively), and low-density lipoprotein (-11.5 [95% CI, -30.8 to 7.7] vs +19.6 [95% CI, 1.9-37.2], respectively). No between-group differences were seen in high-density lipoprotein, blood pressure, or triglycerides.

CONCLUSIONS

Participants receiving the nurse/community health worker-delivered intervention improved their risk CVD profiles, total cholesterol, and low-density lipoprotein levels at 3 months. A larger study to explore the intervention impact on CVD risk factor disparities experienced by rural populations is warranted.

Digital Health-Enabled Community-Centered Care: Scalable Model to Empower Future Community Health Workers Using Human-in-the-Loop Artificial Intelligence

Digital health-enabled community-centered care (D-CCC) represents a pioneering vision for the future of community-centered care. D-CCC aims to support and amplify the digital footprint of community health workers through a novel artificial intelligence-enabled closed-loop digital health platform designed for, and with, community health workers. By focusing digitalization at the level of the community health worker, D-CCC enables more timely, supported, and individualized community health worker-delivered interventions. D-CCC has the potential to move community-centered care into an expanded, digitally interconnected, and collaborative community-centered health and social care ecosystem of the future, grounded within a robust and digitally empowered community health workforce.

How Hypertension Guidelines Address Social Determinants of Health: A Systematic Scoping Review

BACKGROUND

Patient-level and community-level social and economic conditions impact hypertension risk and control. We examined adult hypertension management guidelines to explore whether and how existing guidelines refer to social care activities.

OBJECTIVE

The objective of this study was to explore how hypertension guidelines reference social care activities.

RESEARCH DESIGN

A systematic scoping review of clinical guidelines for adult hypertension management. We employed a PubMed search strategy to identify all hypertension guidelines published in the United States between 1977 and 2019. We reviewed all titles to identify the most updated versions focused on nonpregnant adults with hypertension. We extracted instances where guidelines referred to social determinants of health (SDH) or social care activities. The primary outcome was how guidelines covered social care activities, defined using a framework adapted from the National Academies of Sciences, Engineering, and Medicine (NASEM).

RESULTS

Search terms yielded 126 guidelines. Thirty-six guidelines met the inclusion criteria. Of those, 72% (26/36) recommended social care activities as part of hypertension management; 58% recommended clinicians change clinical practice based on social risk information. These recommendations often lacked specific guidance around how to directly address social risk factors or reduce the impact of these risks on hypertension management. When guidelines referred to specific social factors, patient financial security was the most common. Over time, hypertension guidelines have included more references to SDH.

CONCLUSION

Information about SDH is included in many hypertension guidelines, but few guidelines provide clear guidance for clinicians or health systems on how to identify and address social risk factors in the context of care delivery.

The Use of Community Health Workers in Community Health Centers

BACKGROUND

Until 2016, community health centers (CHCs) reported community health workers (CHWs) as part of their overall enabling services workforce, making analyses of CHW use over time infeasible in the annual Uniform Data System (UDS).

OBJECTIVE

The objective of this study was to examine changes in the CHW workforce among CHCs from 2016 to 2018 and factors associated with the use of CHWs.

RESEARCH DESIGN, SUBJECTS, MEASURES

The two-part model estimated separate effects for the probability of using any CHW and extent of CHW full-time equivalents (FTEs) reported in those CHCs, using a total of 4102 CHC-year observations from 2016 to 2018. To estimate the extent to which increases in CHW workforce are attributable to real growth or rather are a consequence of a change in reporting category, we also conducted a difference-in-differences analysis to compare non-CHW enabling services FTEs between CHCs with and without CHWs before (2013-2015) and after (2016-2018) the reporting change in 2016.

RESULTS

The rate of CHCs that employed CHWs rose from 20.04% in 2016 to 28.34% in 2018, while average FTEs stayed relatively flat (3.32 FTEs). Patient visit volume (larger CHCs) and grant funding (less reliant on federal but more reliant on private funding) were significant factors associated with CHW use. However, we found that a substantial portion of this growth was attributable to a change in UDS reporting categories.

CONCLUSION

While we do not address the reasons why CHCs have been slow to use CHWs, our results point to substantial financial barriers associated with CHCs' expanding the use of CHWs.

Contribution of community health workers to primary health care performance in Brazil

OBJECTIVE

To associate the strength of community health workers interventions with primary health care strategies for women’s and children’s health, diabetes, and hypertension.

METHODS

This is a cross-sectional study assessing 29,778 family health teams working in primary health care in Brazil in 2014. The association between community health workers activity levels and primary health care facilities was analyzed using multiple logistic regression.

RESULTS

We found higher levels of community health workers activities strongly associated with primary health care practices (OR = 6.88) for those activities targeting hypertension management, followed by children’s health (OR = 6.56), and women’s health (OR = 6.21).

CONCLUSIONS

At a time when Brazil discusses whether community health workers should or should not remain in the same scale-up and skill level as they currently are, our results reinforce the importance of these workers for the care model advocated by the Brazilian Unified Health System.

Improving community participation in clinical and translational research: CTSA Sentinel Network proof of concept study

BACKGROUND

Research participation by members of racial or ethnic minority groups continues to be less than optimum resulting in difficulties to generalization of research findings. Community-engaged research that relies on a community health worker (CHW) model has been found effective in building trust in the community, thereby motivating people to participate in health research. The Sentinel Network study aimed at testing the feasibility of utilizing the CHW model to link community members to appropriate health research studies at each of the research sites.

METHODS

The study was conducted at six Clinical and Translational Science Award institutions (N = 2371) across the country; 733 (30.9%) of the participants were from the University of Florida, 525 (22.0%) were from Washington University in St. Louis, 421 (17.8%) were from the University of California, Davis, 288 (12.1%) were from the University of Michigan, Ann Arbor, 250 (10.5%) were from Rochester, and 154 (6.5%) from Albert Einstein College of Medicine. Trained CHWs from each of these sites conducted regular community outreach where they administered a Health Needs Assessment, provided medical and social referrals, and linked to eligible research studies at each of those sites. A 30-day follow-up assessment was developed to track utilization of services satisfaction with the services and research study participation.

RESULTS

A large majority of people, especially African Americans, expressed willingness to participate in research studies. The top two health concerns reported by participants were hypertension and diabetes.

CONCLUSION

Findings on the rate of navigation and enrollment in research from this study indicate the effectiveness of a hybrid CHW service and research model of directly engaging community members to encourage people to participate in research.

An Emerging Model for Community Health Worker-Based Chronic Care Management for Patients With High Health Care Costs in Rural Appalachia

Community health workers (CHWs) can improve patients' health by providing them with ongoing behavioral support during the health care experience, and they help decrease health care costs, especially among patients whose starting costs are high and among underserved and minority populations. We developed a CHW-based care model with the aim of improving outcomes and lowering costs for high-risk diabetes patients in rural Appalachia. Enrolled patients experienced a mean decrease in HbA1c of 2.4 percentage points, and 60% or more of patients with diabetes lowered their blood glucose between baseline and 6 to 12 months after enrollment. As health care providers and patients became familiar with this model of care management, enrollment in the program accelerated.

Adapting an Evidence-based Cardiovascular Disease Risk Reduction Intervention to Rural Communities

PURPOSE

Using the RE-AIM framework, the primary purpose of this qualitative study was to assess focus group data to generate information on the applicability of an evidence-based cardiovascular disease (CVD) risk intervention developed for an urban setting for rural areas in Nebraska. We also sought to determine potential adaptations that may be necessary to implement the study in a rural setting. The CVD risk reduction intervention is based on the Community Outreach and Cardiovascular Health (COACH) program, which included nurse practitioner/community health worker teams.

METHODS

This qualitative study involved conducting 3 focus groups with patients with CVD risk factors to assess community readiness for participating in the intervention, the mode of the delivery of the intervention, the setting of the intervention, program content, and raising awareness of the intervention.

FINDINGS

Findings from the focus groups indicate acceptability toward a CVD risk reduction program modeled after the COACH. Participants favored initial in-person face-to-face interactions with a nurse practitioner that could transition to phone-based meetings and Skype. In addition, participants underscored that confidentiality can be a concern in small communities and therefore community health workers need to be trusted individuals. Calls for additions to COACH materials were very specific and participants underscored the need for social support.

CONCLUSIONS

With minor adaptations, the COACH program can be pilot tested in rural settings to address key health concerns and behaviors that affect risk for cardiovascular health.

Problems Experienced in the Second and Third Months After Discharge From a Heart Failure-Related Hospitalization

The purpose of this study was to identify high-priority problems experienced by individuals during the second and third month after discharge from an acute care facility for heart failure. This descriptive, exploratory study, an extension of a previous analysis that examined high-priority problems in the first month, comprised 19 participants who were assigned to an intervention group that received a randomized, 12-week-pilot coping partnership (COPE-HF) intervention. A trained research nurse provided the intervention, and participants used a standard list to identify high-priority heart failure-related problems. Quantitative and content data analysis was conducted. While the highest-priority problem continued to be managing their treatment regimens, the frequency of this problem lessened by week 12. Comorbidities emerged as a new problem in managing heart failure treatment and symptoms. Coping emerged as a new problem, as individuals with heart failure dealt with the impending morbidity of their diagnosis and how it would affect loved ones. Resource issues (ie, financial, social) became more prevalent for individuals with heart failure as potential and actual resources were depleted. Health providers should develop strategies to address these problems to improve outcomes in individuals with heart failure.

Role of community health workers in type 2 diabetes mellitus self-management: A scoping review

BACKGROUND

Globally the number of people with Type 2 diabetes mellitus (T2DM) has risen significantly over the last few decades. Aligned to this is a growing use of community health workers (CHWs) to deliver T2DM self-management support with good clinical outcomes especially in High Income Countries (HIC). Evidence and lessons from these interventions can be useful for Low- and Middle-Income countries (LMICs) such as South Africa that are experiencing a marked increase in T2DM prevalence.

OBJECTIVES

This study aimed to examine how CHW have been utilized to support T2DM self-management globally, their preparation for and supervision to perform their functions.

METHOD

The review was guided by a stepwise approach outlined in the framework for scoping reviews developed by Arksey and O'Malley. Peer reviewed scientific and grey literature was searched using a string of keywords, selecting English full-text articles published between 2000 and 2015. Articles were selected using inclusion criteria, charted and content analyzed.

RESULTS

1008 studies were identified of which 54 full text articles were selected. Most (53) of the selected studies were in HIC and targeted mostly minority populations in low resource settings. CHWs were mostly deployed to provide education, support, and advocacy. Structured curriculum based education was the most frequently reported service provided by CHWs to support T2DM self-management. Support services included informational, emotional, appraisal and instrumental support. Models of CHW care included facility linked nurse-led CHW coordination, facility-linked CHW led coordination and standalone CHW interventions without facility interaction.

CONCLUSION

CHWs play several roles in T2DM self-management, including structured education, ongoing support and health system advocacy. Preparing and coordinating CHWs for these roles is crucial and needs further research and strengthening.

Community-Based Diabetes Community Health Worker Intervention in an Underserved Chicago Population

The Community Health Worker (CHW) model has been used to combat disparities in healthcare access by utilizing community members as healthcare liaisons to promote improved community health. CHW interventions have been effective in improving diabetes management. This case study reports on a low-intensity CHW intervention in a predominantly Hispanic and non-Hispanic Black population in two Chicago neighborhoods: North Lawndale and South Lawndale. CHWs conducted door-to-door outreach and, for individuals with self-reported type 2 diabetes, offered home visits at baseline and one-year follow-up to provide diabetes education, create an individual management strategy, and refer to clinic-based support services. During 2012, 459 participants were enrolled, with 343 completing follow-up visits in 2013 (75 % retention). The mean HbA1c decrease was 0.5 %. At follow-up, participants were less likely to be depressed, to forget to take their diabetes medications, and were more likely to report higher social support and score higher on an assessment of diabetes knowledge. Patients who were younger, Hispanic, had uncontrolled diabetes, and had lower levels of diabetes self-care at baseline demonstrated increased odds of a significant HbA1c decrease with the intervention than patients without these characteristics. This study demonstrates the effectiveness of a home-based, low-intensity CHW intervention in medically underserved communities, and identifies population groups who might benefit the most from future similar CHW interventions.

Randomized feasibility trial to improve hydroxyurea adherence in youth ages 10-18 years through community health workers: The HABIT study

INTRODUCTION

The main therapeutic intervention for sickle cell disease (SCD) is hydroxyurea (HU). The effect of HU is largely through dose-dependent induction of fetal hemoglobin (HbF). Poor HU adherence is common among adolescents.

METHODS

Our 6-month, two-site pilot intervention trial, "HABIT," was led by culturally aligned community health workers (CHWs). CHWs performed support primarily through home visits, augmented by tailored text message reminders. Dyads of youth with SCD ages 10-18 years and a parent were enrolled. A customized HbF biomarker, the percentage decrease from each patients' highest historical HU-induced HbF, "Personal best," was used to qualify for enrollment and assess HU adherence. Two primary outcomes were as follows: (1) intervention feasibility and acceptability and (2) HU adherence measured in three ways: monthly percentage improvement toward HbF Personal best, proportion of days covered (PDC) by HU, and self-report.

RESULTS

Twenty-eight dyads were enrolled, of which 89% were retained. Feasibility and acceptability were excellent. Controlling for group assignment and month of intervention, the intervention group improved percentage decrease from Personal best by 2.3% per month during months 0-4 (P = 0.30), with similar improvement in adherence demonstrated using pharmacy records. Self-reported adherence did not correlate. Dyads viewed CHWs as supportive for learning about SCD and HU, living with SCD and making progress in coordinated self-management responsibility to support a daily HU habit. Most parents and youth appreciated text message HU reminders.

CONCLUSIONS

The HABIT pilot intervention demonstrated feasibility and acceptability with promising effect toward improved medication adherence. Testing in a larger multisite intervention trial is warranted.

Self-Care for the Prevention and Management of Cardiovascular Disease and Stroke: A Scientific Statement for Healthcare Professionals From the American Heart Association

Self-care is defined as a naturalistic decision-making process addressing both the prevention and management of chronic illness, with core elements of self-care maintenance, self-care monitoring, and self-care management. In this scientific statement, we describe the importance of self-care in the American Heart Association mission and vision of building healthier lives, free of cardiovascular diseases and stroke. The evidence supporting specific self-care behaviors such as diet and exercise, barriers to self-care, and the effectiveness of self-care in improving outcomes is reviewed, as is the evidence supporting various individual, family-based, and community-based approaches to improving self-care. Although there are many nuances to the relationships between self-care and outcomes, there is strong evidence that self-care is effective in achieving the goals of the treatment plan and cannot be ignored. As such, greater emphasis should be placed on self-care in evidence-based guidelines.

Community Health Workers and Use of mHealth: Improving Identification of Pregnancy Complications and Access to Care in the Dominican Republic

This article presents the feasibility and acceptability of using mobile health technology by community health workers (CHWs) in San Juan Province, Dominican Republic, to improve identification of pregnancy complications and access to care for pregnant women. Although most women in the Dominican Republic receive four antenatal care visits, poor women and adolescents in remote areas are more likely to have only one initial prenatal visit to verify the pregnancy. This community-based research began when community leaders raised concern about the numbers of their mothers who died in childbirth annually; San Juan's maternal mortality rate is 144/100,000 compared to the Caribbean rate of 85/100,000. Eight CHWs in three communities were taught to provide third-trimester antenatal assessment, upload the data on a mobile phone application, send the data to the local physician who monitored data for "red flags," and call directly if a mother had an urgent problem. Fifty-two pregnant women enrolled, 38 were followed to delivery, 95 antenatal care postintake were provided, 2 urgent complications required CHW home management of mothers, and there were 0 deaths. Stakeholders endorsed acceptability of intervention. Preliminary data suggest CHWs using mobile health technology is feasible, linking underserved and formal health care systems with provision of primary care in mothers' homes.

Potential for mobile health (mHealth) prevention of cardiovascular diseases in Kerala: A population-based survey

BACKGROUND

India's southern state of Kerala stands at the forefront of India's epidemic of cardiovascular disease (CVD), among other non-communicable diseases (NCDs). Mobile phone use in healthcare (mHealth) has shown promise in India, including NCDs. However, suitability and acceptability of m-Health interventions is poorly researched, particularly in rural settings.

OBJECTIVES

METHODS: A questionnaire regarding mobile phone usage and possible use in healthcare was verbally administered in five primary health centres and by home visits in five village councils ("panchayats") of Ernakulam, Kerala. Adults who spoke Malayalam or English, with access to a mobile phone were recruited by convenience sampling in partnership with accredited social health activists (ASHAs). Quantitative data analysis was conducted using SPSS software.

RESULTS

262 participants were recruited. 87% routinely used and 88% owned a mobile phone. 92% were willing to receive mHealth advice, and 94% favoured mobile medication reminders. 70.3% and 73% preferred voice calls over short messaging service (SMS) for delivering health information and medication reminders, respectively. 85.9% would send home recorded information on their blood pressure, weight, medication use and lifestyle to a doctor or ASHA. 75.2% trusted the confidentiality of mHealth data, while 77.1% had no concerns about the privacy of their information.

CONCLUSIONS

The majority of this population approve mHealth interventions. While further investigation of mHealth as a health education tool is warranted, SMS interventions may fail to maximise equity and penetration across all patient groups.

Effects of Community-Based Health Worker Interventions to Improve Chronic Disease Management and Care Among Vulnerable Populations: A Systematic Review

BACKGROUND

Community-based health workers (CBHWs) are frontline public health workers who are trusted members of the community they serve. Recently, considerable attention has been drawn to CBHWs in promoting healthy behaviors and health outcomes among vulnerable populations who often face health inequities.

OBJECTIVES

We performed a systematic review to synthesize evidence concerning the types of CBHW interventions, the qualification and characteristics of CBHWs, and patient outcomes and cost-effectiveness of such interventions in vulnerable populations with chronic, noncommunicable conditions.

SEARCH METHODS

We undertook 4 electronic database searches-PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and Cochrane-and hand searched reference collections to identify randomized controlled trials published in English before August 2014.

SELECTION

We screened a total of 934 unique citations initially for titles and abstracts. Two reviewers then independently evaluated 166 full-text articles that were passed onto review processes. Sixty-one studies and 6 companion articles (e.g., cost-effectiveness analysis) met eligibility criteria for inclusion.

DATA COLLECTION AND ANALYSIS

Four trained research assistants extracted data by using a standardized data extraction form developed by the authors. Subsequently, an independent research assistant reviewed extracted data to check accuracy. Discrepancies were resolved through discussions among the study team members. Each study was evaluated for its quality by 2 research assistants who extracted relevant study information. Interrater agreement rates ranged from 61% to 91% (average 86%). Any discrepancies in terms of quality rating were resolved through team discussions.

MAIN RESULTS

All but 4 studies were conducted in the United States. The 2 most common areas for CBHW interventions were cancer prevention (n = 30) and cardiovascular disease risk reduction (n = 26). The roles assumed by CBHWs included health education (n = 48), counseling (n = 36), navigation assistance (n = 21), case management (n = 4), social services (n = 7), and social support (n = 18). Fifty-three studies provided information regarding CBHW training, yet CBHW competency evaluation (n = 9) and supervision procedures (n = 24) were largely underreported. The length and duration of CBHW training ranged from 4 hours to 240 hours with an average of 41.3 hours (median: 16.5 hours) in 24 studies that reported length of training. Eight studies reported the frequency of supervision, which ranged from weekly to monthly. There was a trend toward improvements in cancer prevention (n = 21) and cardiovascular risk reduction (n = 16). Eight articles documented cost analyses and found that integrating CBHWs into the health care delivery system was associated with cost-effective and sustainable care.

CONCLUSIONS

Interventions by CBHWs appear to be effective when compared with alternatives and also cost-effective for certain health conditions, particularly when partnering with low-income, underserved, and racial and ethnic minority communities. Future research is warranted to fully incorporate CBHWs into the health care system to promote noncommunicable health outcomes among vulnerable populations.

Community health workers in primary care practice: redesigning health care delivery systems to extend and improve diabetes care in underserved populations

New, comprehensive, approaches for chronic disease management are needed to ensure that patients, particularly those more likely to experience health disparities, have access to the clinical care, self-management resources, and support necessary for the prevention and control of diabetes. Community health workers (CHWs) have worked in community settings to reduce health care disparities and are currently being deployed in some clinical settings as a means of improving access to and quality of care. Guided by the chronic care model, Baylor Health Care System embedded CHWs within clinical teams in community clinics with the goal of reducing observed disparities in diabetes care and outcomes. This study examines findings from interviews with patients, CHWs, and primary care providers (PCPs) to understand how health care delivery systems can be redesigned to effectively incorporate CHWs and how embedding CHWs in primary care teams can produce informed, activated patients and prepared, proactive practice teams who can work together to achieve improved patient outcomes. Respondents indicated that the PCPs continued to provide clinical exams and manage patient care, but the roles of diabetes education, nutritional counseling, and patient activation were shifted to the CHWs. CHWs also provided patients with social support and connection to community resources. Integration of CHWs into clinical care teams improved patient knowledge and activation levels, the ability of PCPs to identify and proactively address specific patient needs, and patient outcomes.

Strengthening the Effectiveness of State-Level Community Health Worker Initiatives Through Ambulatory Care Partnerships

The transformation of the US health care system and the recognition of the effectiveness of community health workers (CHWs) have accelerated national, state, and local efforts to engage CHWs in the support of vulnerable populations. Much can be learned about how to successfully integrate CHWs into health care teams, how to maximize their impact on chronic disease self-management, and how to strengthen their role as emissaries between clinical services and community resources; we share examples of effective strategies. Ambulatory care staff members are key partners in statewide initiatives to build and sustain the CHW workforce and reduce health disparities.

Clinicians' panel management self-efficacy to support their patients' smoking cessation and hypertension control needs

Panel management, a set of tools and processes for proactively caring for patient populations, has potential to reduce morbidity and improve outcomes between office visits. We examined primary care staff's self-efficacy in implementing panel management, its correlates, and an intervention's impact on this self-efficacy. Primary care teams at two Veterans Health Administration (VA) hospitals were assigned to control or intervention conditions. Staff were surveyed at baseline and post-intervention, with a random subset interviewed post-intervention. Panel management self-efficacy was higher among staff participating in the panel management intervention. Self-efficacy was significantly correlated with sufficient training, aspects of team member interaction, and frequency of panel management use. Panel management self-efficacy was modest among primary care staff at two VA hospitals. Team level interventions may improve primary care staff's confidence in practicing panel management, with this greater confidence related to greater team involvement with, and use of panel management.

Cost-effectiveness of nurse practitioner/community health worker care to reduce cardiovascular health disparities

BACKGROUND

Although evidence-based guidelines on the management of cardiovascular disease (CVD) and type 2 diabetes have been widely published, implementation of recommended therapies is suboptimal.

OBJECTIVE

The aim of this study was to evaluate the cost-effectiveness of a comprehensive program of CVD risk reduction delivered by nurse practitioner/community health worker (NP/CHW) teams versus enhanced usual care to improve lipids, blood pressure (BP), and hemoglobin (Hb) A1c levels in patients in urban community health centers.

METHODS

A total of 525 patients with documented CVD, type 2 diabetes, hypercholesterolemia, or hypertension and levels of low-density lipoprotein cholesterol, BP, or Hb A1c that exceeded goals established by national guidelines were randomized to NP/CHW (n = 261) or enhanced usual care (n = 264) groups. Cost-effectiveness ratios were calculated, determining costs per percent and unit change in the primary outcomes.

RESULTS

The mean incremental total cost per patient (NP/CHW and physician) was only $627 (confidence interval, 248-1015). The cost-effectiveness of the 1-year intervention was $157 for every 1% drop in systolic BP and $190 for every 1% drop in diastolic BP, $149 per 1% drop in Hb A1c, and $40 per 1% drop in low-density lipoprotein cholesterol.

CONCLUSIONS

The findings suggest that management by an NP/CHW team is a cost-effective approach for community health centers to consider in improving the care of patients with existing CVD or at high risk for the development of CVD.

Implementing a working together model for Aboriginal patients with acute coronary syndrome: an Aboriginal Hospital Liaison Officer and a specialist cardiac nurse working together to improve hospital care

Acute coronary syndrome (ACS) contributes to the disparity in life expectancy between Aboriginal and non-Aboriginal Australians. Improving hospital care for Aboriginal patients has been identified as a means of addressing this disparity. This project developed and implemented a working together model of care, comprising an Aboriginal Hospital Liaison Officer and a specialist cardiac nurse, providing care coordination specifically directed at improving attendance at cardiac rehabilitation services for Aboriginal Australians in a large metropolitan hospital in Melbourne. A quality improvement framework using a retrospective case notes audit evaluated Aboriginal patients' admissions to hospital and identified low attendance rates at cardiac rehabilitation services. A working together model of care coordination by an Aboriginal Hospital Liaison Officer and a specialist cardiac nurse was implemented to improve cardiac rehabilitation attendance in Aboriginal patients admitted with ACS to the cardiac wards of the hospital. A retrospective medical records audit showed that there were 68 Aboriginal patients admitted to the cardiac wards with ACS from 1 July 2008 to 30 June 2011. A referral to cardiac rehabilitation was recorded for 42% of these. During the implementation of the model of care, 13 of 15 patients (86%) received a referral to cardiac rehabilitation and eight of the 13 (62%) attended. Implementation of the working together model demonstrated improved referral to and attendance at cardiac rehabilitation services, thereby, has potential to prevent complications and mortality. WHAT IS KNOWN ABOUT THE TOPIC?: Aboriginal Australians experience disparities in access to recommended care for acute coronary syndrome. This may contribute to the life expectancy gap between Aboriginal and non-Aboriginal Australians. WHAT DOES THIS PAPER ADD?: This paper describes a model of care involving an Aboriginal Hospital Liaisons Officer and a specialist cardiac nurse working together to improve hospital care and attendance at cardiac rehabilitation services for Aboriginal Australians with acute coronary syndrome. WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS?: The working together model of care could be implemented across mainstream health services where Aboriginal people attend for specialist care.

Building skill in heart failure self-care among community dwelling older adults: results of a pilot study

OBJECTIVE

Most of the day-to-day care for heart failure (HF) is done by the patient at home and requires skill in self-care. In this randomized controlled trial (RCT) we tested the efficacy of a community-based skill-building intervention on HF self-care, knowledge and health-related quality of life (HRQL) at 1- and 3-months.

METHODS

An ethnically diverse sample (n=75) of patients with HF (53% female; 32% Hispanic, 27% Black; mean age 69.9±10 years) was randomized to the intervention group (IG) or a wait-list control group (CG). The protocol intervention focused on tactical and situational HF self-care skill development delivered by lay health educators in community senior centers. Data were analyzed using mixed (between-within subjects) ANOVA.

RESULTS

There was a significant improvement in self-care maintenance [F(2,47)=3.42, p=.04, (Cohen's f=.38)], self-care management [F(2,41)=4.10, p=.02, (Cohen's f=.45) and HF knowledge [F(2,53)=8.00, p=.001 (Cohen's f=.54)] in the IG compared to the CG.

CONCLUSIONS

The skill-building intervention improved self-care and knowledge but not HRQL in this community-dwelling sample.

PRACTICE IMPLICATIONS

Delivering an intervention in a community setting using lay health educators provides an alternative to clinic- or home-based teaching that may be useful across diverse populations and geographically varied settings.

A cost analysis of a community health worker program in rural Vermont

Studies have shown that community health workers (CHWs) can improve the effectiveness of health care systems; however, little has been reported about CHW program costs. We examined the costs of a program staffed by three CHWs associated with a small, rural hospital in Vermont. We used a standardized data collection tool to compile cost information from administrative data and personal interviews. We analyzed personnel and operational costs from October 2010 to September 2011. The estimated total program cost was $420,348, a figure comprised of $281,063 (67%) for personnel and $139,285 (33%) for operations. CHW salaries and office space were the major cost components. Our cost analysis approach may be adapted by others to conduct cost analyses of their CHW program. Our cost estimates can help inform future economic studies of CHW programs and resource allocation decisions.

The need to advance nutrition education in the training of health care professionals and recommended research to evaluate implementation and effectiveness

Nutrition is a recognized determinant in 3 (ie, diseases of the heart, malignant neoplasms, cerebrovascular diseases) of the top 4 leading causes of death in the United States. However, many health care providers are not adequately trained to address lifestyle recommendations that include nutrition and physical activity behaviors in a manner that could mitigate disease development or progression. This contributes to a compelling need to markedly improve nutrition education for health care professionals and to establish curricular standards and requisite nutrition and physical activity competencies in the education, training, and continuing education for health care professionals. This article reports the present status of nutrition and physical activity education for health care professionals, evaluates the current pedagogic models, and underscores the urgent need to realign and synergize these models to reflect evidence-based and outcomes-focused education.

Community health workers in low-, middle-, and high-income countries: an overview of their history, recent evolution, and current effectiveness

Over the past half-century, community health workers (CHWs) have been a growing force for extending health care and improving the health of populations. Following their introduction in the 1970s, many large-scale CHW programs declined during the 1980s, but CHW programs throughout the world more recently have seen marked growth. Research and evaluations conducted predominantly during the past two decades offer compelling evidence that CHWs are critical for helping health systems achieve their potential, regardless of a country's level of development. In low-income countries, CHWs can make major improvements in health priority areas, including reducing childhood undernutrition, improving maternal and child health, expanding access to family-planning services, and contributing to the control of HIV, malaria, and tuberculosis infections. In many middle-income countries, most notably Brazil, CHWs are key members of the health team and essential for the provision of primary health care and health promotion. In the United States, evidence indicates that CHWs can contribute to reducing the disease burden by participating in the management of hypertension, in the reduction of cardiovascular risk factors, in diabetes control, in the management of HIV infection, and in cancer screening, particularly with hard-to-reach subpopulations. This review highlights the history of CHW programs around the world and their growing importance in achieving health for all.

The role of community health workers in diabetes: update on current literature

Community health worker (CHW) interventions have been found to be a promising strategy for improving diabetes outcomes, especially among low-income and racial and ethnic minority populations. This review serves as an update of the literature published since 2011 on CHWs' role in diabetes care. In our review of the most current literature, we noted several key areas of advancement. These areas include community-based participatory research approaches to intervention development and evaluation, analyses of the cost effectiveness of CHW interventions, evaluation of sustainability through integrated team-based approaches, thorough descriptions of characteristics and training of CHWs, and delineation of the scope of practice and most effective roles for CHWs.

Randomized controlled pilot study testing use of smartphone technology for obesity treatment

BACKGROUND

The established interventions for weight loss are resource intensive which can create barriers for full participation and ultimate translation. The major goal of this pilot study was to evaluate the feasibility, acceptability, and preliminary efficacy of theoretically based behavioral interventions delivered by smartphone technology.

METHODS

The study randomized 68 obese adults to receive one of four interventions for six months: (1) intensive counseling intervention, (2) intensive counseling plus smartphone intervention, (3) a less intensive counseling plus smartphone intervention, and (4) smartphone intervention only. The outcome measures of weight, BMI, waist circumference, and self-reported dietary intake and physical activity were assessed at baseline and six months.

RESULTS

The sample was 78% female and 49% African American, with an average age of 45 years, and average BMI of 34.3 kg/m(2). There were trends for differences in weight loss among the four intervention groups. Participants in the intensive counseling plus self-monitoring smartphone group and less intensive counseling plus self-monitoring smartphone group tended to lose more weight than other groups (5.4 kg and 3.3 kg, resp.).

CONCLUSIONS

The results of this pilot trial of a weight loss intervention provide preliminary support for using a smartphone application for self-monitoring as an adjunct to behavioral counseling.

Community Outreach and Cardiovascular Health (COACH) Trial: a randomized, controlled trial of nurse practitioner/community health worker cardiovascular disease risk reduction in urban community health centers

BACKGROUND

Despite well-publicized guidelines on the appropriate management of cardiovascular disease and type 2 diabetes, the implementation of risk-reducing practices remains poor. This report describes the results of a randomized, controlled clinical trial evaluating the effectiveness of a comprehensive program of cardiovascular disease risk reduction delivered by nurse practitioner /community health worker (NP/CHW) teams versus enhanced usual care (EUC) to improve lipids, blood pressure, glycated hemoglobin (HbA1c), and patient perceptions of the quality of their chronic illness care in patients in urban community health centers.

METHODS AND RESULTS

A total of 525 patients with documented cardiovascular disease, type 2 diabetes, hypercholesterolemia, or hypertension and levels of LDL cholesterol, blood pressure, or HbA1c that exceeded goals established by national guidelines were randomly assigned to NP/CHW (n=261) or EUC (n=264) groups. The NP/CHW intervention included aggressive pharmacological management and tailored educational and behavioral counseling for lifestyle modification and problem solving to address barriers to adherence and control. Compared with EUC, patients in the NP/CHW group had significantly greater 12-month improvement in total cholesterol (difference, 19.7 mg/dL), LDL cholesterol (difference,15.9 mg/dL), triglycerides (difference, 16.3 mg/dL), systolic blood pressure (difference, 6.2 mm Hg), diastolic blood pressure (difference, 3.1 mm Hg), HbA1c (difference, 0.5%), and perceptions of the quality of their chronic illness care (difference, 1.2 points).

CONCLUSIONS

An intervention delivered by an NP/CHW team using individualized treatment regimens based on treat-to-target algorithms can be an effective approach to improve risk factor status and perceptions of chronic illness care in high-risk patients.
