CHW-roles and opportunities in healthcare delivery system reform by John e. Snyder, ASPE Issue Brief, January 2016.
Community Health Workers (CHWs) are an emerging group of health professionals that have recently drawn increased national attention because of their potential to deliver cost-effective, high quality, and culturally competent health services within team-based care models. The apparent benefits of integrating CHWs into health care teams seem to depend on context. The strongest evidence of these benefits supports utilizing CHWs to deliver certain specific, high-value, preventive services – focused on reducing risk factors for cardiovascular disease and other chronic conditions – to low-income, minority, or other underserved populations. Despite growing interest in engaging CHWs in national delivery system reform efforts, there are several uncertainties about how to best proceed with this. Questions remain around standardizing CHW training, certification, and licensure; establishing strong economic and other evidence to support their use; and securing reimbursement for their services to ensure financial sustainability of CHW programs. https://aspe.hhs.gov/sites/default/files/pdf/168956/CHWPolicy.pdf

States Implementing Community Health Worker Strategies
This new technical assistance guide summarizes the successful work of organizations as it relates to Domains 3 and 4 (Health Systems Interventions and Community-Clinical Linkages, respectively) of CDC’s State Public Health Actions program (CDC-RFA-DP13-1305). It also offers insights for states that are implementing CHW strategies. Recommendations were developed by compiling interviews with 9 organizations experienced in integrating CHWs into healthcare teams and engaging CHWs in promoting linkages between the health care system and community resources. Additional findings from a review of evidence-based literature are also included.
Campbell JD, Brooks M, Hosokawa P, et al. Community health worker home visits for medicaid-enrolled children with asthma: effects on asthma outcomes and costs. Am J Public Health. 2015 Nov;105(11):2366-72.
Objectives: We sought to estimate the return on investment of a streamlined version of an evidence-based community health worker (CHW) asthma home visit program. Methods: We used a randomized parallel group trial of home visits by CHWs to Medicaid-enrolled children with uncontrolled asthma versus usual care. Results: A total of 373 participants enrolled in the study (182 in the intervention group and 191 in the control group, of whom 154 and 179, respectively, completed the study). The intervention group had greater improvements in asthma symptom-free days (2.10 days more over 2 weeks; 95% CI = 1.17, 3.05; P < .001) and caretakers' quality of life (0.43 units more; 95% CI = 0.20, 0.66; P < .001) and a larger reduction in urgent health care utilization events (1.31 events fewer over 12 months; 95% CI = -2.10, -0.52; P = .001). The intervention arm compared with the control arm saved $1340.92 for the $707.04 additional costs invested for the average participant. The return on investment was 1.90. Conclusions: A streamlined CHW asthma home visit program for children with uncontrolled asthma improved health outcomes and yielded a return on investment of 1.90.
Castaneda SF, Giacinto RE, Medeiros EA, Brongiel I, Cardona O, Perez P, Talavera GA. Academic-community partnership to develop a patient-centered breast cancer risk reduction program for Latina primary care patients. J Racial Ethn Health Disparities. 2016 Jun;3(2):189-99.
This collaborative study sought to address Latina breast cancer (BC) disparities by increasing health literacy (HL) in a community health center situated on the US-Mexico border region of San Diego County. An academic-community partnership conducted formative research to develop a culturally tailored promotora-based intervention with 109 individuals. The Spanish language program, entitled Nuestra Cocina: Mesa Buena, Vida Sana (Our Kitchen: Good Table, Healthy Life), included six sessions targeting HL, women's health, BC risk reduction, and patient-provider communication; sessions include cooking demonstrations of recipes with cancer-risk-reducing ingredients. A pilot study with 47 community health center Latina patients was conducted to examine the program's acceptability, feasibility, and ability to impact knowledge and skills. Pre- and post-analyses demonstrated that participants improved their self-reported cancer screening, BC knowledge, daily fruit and vegetable intake, and ability to read a nutrition label (p < 0.05). Results of the pilot study demonstrate the importance of utilizing patient-centered culturally appropriate noninvasive means to educate and empower Latina patients.
Coronado GD, Beresford SA, McLerran D, et al. Multilevel intervention raises Latina participation in mammography screening: findings from ¡Fortaleza Latina! Cancer Epidemiol Biomarkers Prev. 2016 Apr;25(4):584-92.
Background: Breast cancer is the most commonly diagnosed cancer in women in the United States, and Latinas have relatively low rates of screening participation. The Multilevel Intervention to Increase Latina Participation in Mammography Screening study (¡Fortaleza Latina!) sought to assess the efficacy of a clinic- and patient-level program to increase breast cancer screening among Latinas in Western Washington who seek care at a safety net health center. Methods: The study enrolled 536 Latinas ages 42 to 74 who had a primary care clinic visit in the previous 5 years and had not obtained a mammogram in the previous 2 years. Participants were block-randomized within clinic to either (i) a control arm (usual care) or (ii) a promotora-led, motivational interviewing intervention that included a home visit and telephone follow-up. At the clinic level, two of four participating clinics were provided additional mammography services delivered by a mobile mammography unit. Results: Rates of screening mammography 1 year post-randomization were 19.6% in the intervention group and 11.0% in the usual care group (P < 0.01), based on medical record data. No significant differences in participants' mammography screening were observed in clinics randomized to additional mammography services versus usual care (15.8% vs. 14.4%; P = 0.68). Conclusion: This multilevel intervention of promotora-delivered motivational interviewing and free mammography services modestly raised rates of participation in breast cancer screening among Latinas. Impact: Our findings can inform future efforts to boost mammography participation in safety net practices.

Objectives: To quantify the characteristics of community health workers (CHWs) involved in community intervention research and, in particular, to characterize their job titles, roles, and responsibilities; recruitment and compensation; and training and supervision. Methods: We developed and administered a structured questionnaire consisting of 25 closed- and open-ended questions to staff on National Institutes of Health-funded Centers for Population Health and Health Disparities projects between March and April 2014. We report frequency distributions for CHW roles, sought-after skills, education requirements, benefits and incentives offered, and supervision and training activities. Results: A total of 54 individuals worked as CHWs across the 18 research projects and held a diverse range of job titles. The CHWs commonly collaborated on research project implementation, provided education and support to study participants, and collected data. Training was offered across projects to bolster CHW capacity to assist in intervention and research activities. Conclusions: Our experience suggests national benefit in supporting greater efforts to recruit, retain, and support the work of CHWs in community-engagement research.
Johnson SL, Gunn VL. Community health workers as a component of the health care team. Pediatr Clin North Am. 2015 Oct;62(5):1313-28.
In restructuring the delivery of primary care to improve the wellness of a community, every community must review its own circumstances for factors such as resources and capacities, health concerns, social and political perspectives, and competing priorities. Strengthening the health care team with community health workers to create a patient-centered medical home can enhance health care access and outcomes. Community health workers can serve as critical connectors between health systems and communities; they facilitate access to and improve quality and culturally sensitive medical care, emphasizing preventive and primary care.
Kyounghae K, Choi JS, Eunsuk C, et al. Effects of community-based health worker interventions to improve chronic disease management and care among vulnerable populations: a systematic review. Am J Public Health. 2016 Apr;106(4):e3-e28.
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, non-communicable 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 under-reported. The length and duration of CBHW training ranged from 4 hours to 240 hours with an average of 41.3 hours (median: 1 6.5 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 in to 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.
Luque JS, Tarasenko YN, Reyes-Garcia C, et al. Salud es Vida: a Cervical Cancer Screening Intervention for Rural Latina Immigrant Women. J Cancer Educ. 2016 Jan 12. [Epub ahead of print]
This study examined the feasibility and efficacy of Salud es Vida-a promotora-led, Spanish language educational group session on cervical cancer screening (Pap tests)-self-efficacy (belief in ability to schedule and complete a Pap test), and knowledge among immigrant Hispanic/Latina women from farmworker backgrounds. These women are disproportionately burdened with cervical cancer, with mortality rates significantly higher than non-Hispanic whites. The two-arm, quasi-experimental study was conducted in four rural counties of Southeast Georgia in 2014-2015. Hispanic/Latina immigrant women aged 21-65 years and overdue for a Pap test were included as intervention (N = 38) and control (N = 52) group participants. The intervention was developed in partnership with a group of promotoras to create the toolkit of materials which includes a curriculum guide, a brochure, a flipchart, a short animated video, and in-class activities. Twelve (32 %) intervention group participants received the Pap test compared to 10 (19 %) control group participants (p = 0.178). The intervention group scored significantly higher on both cervical cancer knowledge recall and retention than the control group (p < 0.001). While there was no statistically significant difference in cervical cancer screening self-efficacy scores between the group participants, both groups scored higher at follow-up, adjusting for the baseline scores. The group intervention approach was associated with increased cervical cancer knowledge but not uptake of Pap test. More intensive interventions using patient navigation approaches or promotoras who actively follow participants or conducting one-on-one rather than group sessions may be needed to achieve improved screening outcomes with this population.
Molokwu J, Penaranda E, Flores S, Shokar NK. Evaluation of the effect of a promotora-led educational intervention on cervical cancer and human papillomavirus knowledge among predominantly Hispanic primary care patients on the US-Mexico Border. J Cancer Educ. 2015 Oct 27. [Epub ahead of print]
Despite declining cervical cancer rates, ethnic minorities continue to bear an unequal burden in morbidity and mortality. While access to screening is a major barrier, low levels of knowledge and cultural influences have been found to play a part in underutilization of preventive services. The aim of our study was to evaluate the effect of a promotora-led educational intervention on cervical cancer and human papillomavirus knowledge in mainly Hispanic females attending a primary care clinic. One hundred ten females were recruited from the waiting room of a busy primary care clinic and invited to attend individual or small group educational sessions. Participants completed knowledge surveys pre- and post-intervention. An overall evaluation of the educational session was also completed. Following the educational intervention, participants showed an improvement in knowledge scores from a mean score of 10.8 (SD 3.43) out of a possible score of 18 to a mean score of 16.0 (SD1.51) (p < 0.001). 94.5 % of participants rated as excellent, the presentation of information in a way that was easy to understand, most reported that it was a good use of their time and that it lowered their anxiety about testing for early detection of cervical cancer. An educational intervention delivered by well-trained Promotora/Lay health care worker significantly improves patient's cervical cancer and HPV knowledge and can be a useful tool in patient education in the clinical setting especially with high risk populations.
Moore AA, Karno MP, Ray L, et al. Development and preliminary testing of a promotora-delivered, Spanish language, counseling intervention for heavy drinking among male, Latino day laborers. J Subst Abuse Treat. 2016 Mar;62:96-101.
This study developed and then tested the feasibility, acceptability and initial efficacy of a 3-session, culturally adapted, intervention combining motivational enhancement therapy (MET) and strengths-based case management (SBCM) delivered by promotoras in Spanish to reduce heavy drinking among male, Latino day laborers. A pilot two-group randomized trial (N=29) was conducted to evaluate the initial efficacy of MET/SBCM compared to brief feedback (BF). Alcohol-related measures were assessed at 6, 12 and 18 weeks after baseline. Most intervention group participants (12/14) attended all counseling sessions and most participants (25/29) remained in the study at 18 weeks. Alcohol related measures improved in both groups over time with no statistically significant differences observed at any of the time points. However the comparative effect size of MET/SBCM on weekly drinking was in the large range at 6-weeks and in the moderate range at 12-weeks. Post hoc analyses identified a statistically significant reduction in number of drinks over time for participants in the intervention group but not for control group participants. Despite the extreme vulnerability of the population, most participants completed all sessions of MET/SBCM and reported high satisfaction with the intervention. We feel our community partnership facilitated these successes. Additional studies of community-partnered and culturally adapted interventions are needed to reduce heavy drinking among the growing population of Latinos in the U.S.

Community-engaged researchers who work with low-income communities can be reliant on grant funding. We use the illustrative case of the Penn Center for Community Health Workers (PCCHW) to describe a step-by-step framework for achieving financial sustainability for community-engaged research interventions. PCCHW began as a small grant-funded research project but followed an 8-step framework to engage both low-income patients and funders, determine outcomes, and calculate return on investment. PCCHW is now fully funded by Penn Medicine and delivers the Individualized Management for Patient-Centered Targets (IMPaCT) community health worker intervention to 2000 patients annually.
Nguyen BH, Stewart SL, Nguyen TT, et al. Effectiveness of lay health worker outreach in reducing disparities in colorectal cancer screening in Vietnamese Americans. Am J Public Health. 2015 Oct;105(10):2083-9.
Objectives: We conducted a cluster randomized controlled study of a lay health worker (LHW) intervention to increase colorectal cancer (CRC) screening rates among Vietnamese Americans, who typically have lower rates than do non-Hispanic Whites. Methods: We randomized 64 LHWs to 2 arms. Each LHW recruited 10 male or female participants who had never had CRC screening (fecal occult blood test, sigmoidoscopy, or colonoscopy). Intervention LHWs led 2 educational sessions on CRC screening. Control LHWs led 2 sessions on healthy eating and physical activity. The main outcome was self-reported receipt of any CRC screening at 6 months after the intervention. We conducted the study from 2008 to 2013 in Santa Clara County, California. Results: A greater proportion of intervention participants (56%) than control participants (19%) reported receiving CRC screening (P < .001). When controlling for demographic characteristics, the intervention odds ratio was 5.45 (95% confidence interval = 3.02, 9.82). There was no difference in intervention effect by participant gender. Conclusions: LHW outreach was effective in increasing CRC screening in Vietnamese Americans. Randomized controlled trials are needed to test the effectiveness of LHW outreach for other populations and other health outcomes.
Richardson BS, Willig AL, Agne AA, Cherrington AL. Diabetes connect: African American women's perceptions of the community health worker model for diabetes care. J Community Health. 2015 Oct;40(5):905-11.
Community health worker (CHW) interventions have potential to improve diabetes outcomes and reduce health disparities. However, few studies have explored patient perspectives of peer-delivered diabetes programs. The purpose of this qualitative study is to investigate possible benefits as well as risks of CHW-delivered peer support for diabetes from the perspectives of African American women living with type 2 diabetes in Jefferson County, Alabama. Four ninety-minute focus groups were conducted by a trained moderator with a written guide to facilitate discussion on the topic of CHWs and diabetes management. Participants were recruited from the diabetes education database at a safety-net hospital. Two independent reviewers performed content analysis to identify major themes using a combined deductive-inductive approach. There were 25 participants. Mean years with diabetes was 11.2 (range 6 months to 42 years). Participants were knowledgeable about methods for self-management but reported limited resources and stress as major barriers. Preferred CHW roles included liaison to the healthcare system and easily accessible information source. Participants preferred that the CHW be knowledgeable and have personal experience managing their own diabetes or assisting a family member with diabetes. Concerns regarding the CHW-model were possible breaches of confidentiality and privacy. The self-management strategies and barriers to management identified by participants were reflected in their preferred CHW roles and traits. These results suggest that African American women with diabetes in Alabama would support peer-led diabetes education that is community-based and socially and emotionally supportive.
Rios-Ellis B, Nguyen-Rodriguez ST, Espinoza L, et al. Engaging community with promotores de salud to support infant nutrition and breastfeeding among Latinas residing in Los Angeles County: Salud con Hyland's. Health Care Women Int. 2015;36(6):711-29.
The Salud con Hyland's Project: Comienzo Saludable, Familia Sana [Health With Hyland's Project: Healthy Start, Healthy Family],was developed to provide education and support to Latina mothers regarding healthy infant feeding practices and maternal health. The promotora-delivered intervention was comprised of two charlas (educational sessions) and a supplemental, culturally and linguistically relevant infant feeding and care rolling calendar. Results indicate that the intervention increased intention to breastfeed exclusively, as well as to delay infant initiation of solids by 5 to 6 months. Qualitative feedback identified barriers to maternal and child health education as well as highlighted several benefits of the intervention.
Shahidi H, Sickora C, Clancy S, Nagurka R. Community health workers recruitment from within: an inner-city neighborhood-driven framework. BMC Res Notes. 2015 Nov 24;8:715. doi: 10.1186/s13104-015-1700-0.
Background: Community health workers (CHWs) are frontline public health workers who are trusted members of and/or have an unusually close understanding of the community served (APHA 2009). Among other roles, they are effective in closing critical communication gap between healthcare providers and patients as they possess key abilities to overcome cultural barriers, minimize disparities, and maximize adherence to clinical directions. In previous descriptions of the selection of CHWs, the role of community is clearly emphasized, but residence in the community is not indicated. Objective: We present an effective model of CHW selection by the community of members that reside in the community to be served. Methods: We outlined and implemented necessary steps for recruiting CHWs from within their target neighborhood between years 2011 and 2013. The identified community was an "isolated" part of Newark, New Jersey comprised of approximately 3000 people residing in three publicly-funded housing developments. We utilized a community empowerment model and established a structure of self-governance in the community of interest. In all phases of identification and selection of CHWs, the Community Advisory Board (CAB) played a leading role. Results: The process for the successful development of a CHW initiative in an urban setting begins with community/resident engagement and ends with employment of trained CHWs. The steps needed are: (1) community site identification; (2) resident engagement; (3) health needs assessment; (4) CHW identification and recruitment; and (5) training and employment of CHWs. Using an empowered community model, we successfully initiated CHW selection, training, and recruitment. Thirteen CHW candidates were selected and approved by the community. They entered a 10-week training program and ten CHWs completed the training. We employed these ten CHWs. Conclusions: These five steps emerged from a retrospective review of our CHW initiative. Residing in the community served has significant advantages and disadvantages. Community empowerment is critical in changing the health indices of marginalized communities.
Shokar NK, Byrd T, Salaiz R, et al. Against colorectal cancer in our neighborhoods (ACCION): A comprehensive community-wide colorectal cancer screening intervention for the uninsured in a predominantly Hispanic community. Prev Med. 2016 Aug 26. pii: S0091-7435(16)30251-1. doi: 10.1016/j.ypmed.2016.08.039. [Epub ahead of print]
Colorectal cancer (CRC) is the second leading cause of cancer deaths in the USA. Screening is widely recommended but underutilized, particularly among the low income, the uninsured, recent immigrants and Hispanics. The study objective was to determine the effectiveness of a comprehensive community-wide, bilingual, CRC screening intervention among uninsured predominantly Hispanic individuals. This prospective study was embedded in a CRC screening program and utilized a quasi-experimental design. Recruitment occurred from Community and clinic sites. Inclusion criteria were aged 50-75years, uninsured, due for CRC screening, Texas address and exclusions were a history of CRC, or recent rectal bleeding. Eligible subjects were randomized to either promotora (P), video (V), or combined promotora and video (PV) education, and also received no-cost screening with fecal immunochemical testing or colonoscopy and navigation. The non-randomly allocated controls recruited from a similar county, received no intervention. The main outcome was 6month self-reported CRC screening. Per protocol and worst case scenario analyses, and logistic regression with covariate adjustment were performed.784 subjects (467 in intervention group, 317 controls) were recruited; mean age was 56.8years; 78.4% were female, 98.7% were Hispanic and 90.0% were born in Mexico. In the worst case scenario analysis (n=784) screening uptake was 80.5% in the intervention group and 17.0% in the control group [relative risk 4.73, 95% CI: 3.69-6.05, P<0.001]. No educational group differences were observed. Covariate adjustment did not significantly alter the effect. A multicomponent community-wide, bilingual, CRC screening intervention significantly increased CRC screening in an uninsured predominantly Hispanic population.
