Acceptability of a community health worker intervention to improve the oral health of older Chinese Americans: A pilot study.

OBJECTIVE: To evaluate the acceptability of a community health worker (CHW) intervention designed to improve the oral health of low-income, urban Chinese immigrant adults. BACKGROUND: Given that both dental caries and periodontitis are behaviourally mediated, biofilm-based diseases that are largely preventable with attention to regular oral hygiene practices and preventive dental visits, strategies to arrest or even heal carious lesions and high-quality maintenance care and plaque control without the need to resort to aerosol-generating surgical approaches are evidence-based best practices. Older immigrants have poorer oral health than older US-born natives, motivating the need for delivery of more effective and affordable services to this vulnerable population. MATERIALS AND METHODS: CHWs were trained by the NYU College of Dentistry dental hygienist faculty members using dental models and flip charts to instruct patients on proper brushing and flossing techniques. In addition, they discussed the presented oral health promotion information one-on-one with patients, addressed any expressed concerns and encouraged prevention of oral conditions through regular dental visits and brushing with fluoride toothpaste. RESULTS: More than 98% of the 74 older Chinese adult participants strongly agreed/agreed that the CHWs helped them to improve how they take care of their health, the CHWs answered their questions and concerns, the information and topics were informative, and the in-person demonstrations were helpful in improving oral health. CONCLUSION: The health of all communities depends on access to comprehensive care, including oral health care, in the wake of COVID-19. CHW interventions are acceptable to and may reach marginalised and immigrant communities.

Disparities in Access to Oral Health Care.

In the United States, people are more likely to have poor oral health if they are low-income, uninsured, and/or members of racial/ethnic minority, immigrant, or rural populations who have suboptimal access to quality oral health care. As a result, poor oral health serves as the national symbol of social inequality. There is increasing recognition among those in public health that oral diseases such as dental caries and periodontal disease and general health conditions such as obesity and diabetes are closely linked by sharing common risk factors, including excess sugar consumption and tobacco use, as well as underlying infection and inflammatory pathways. Hence, efforts to integrate oral health and primary health care, incorporate interventions at multiple levels to improve access to and quality of services, and create health care teams that provide patient-centered care in both safety net clinics and community settings may narrow the gaps in access to oral health care across the life course.

A survey of caregiver acculturation and acceptance of silver diamine fluoride treatment for childhood caries.

BACKGROUND: Interest in aqueous silver diamine fluoride (SDF) has been growing as a treatment for caries arrest. A cross-sectional study was conducted to identify factors associated with caregiver acceptance of SDF treatment for children presenting with caries at 8 Federally Qualified Health Centers. The study purpose was to examine associations between caregiver acceptance of SDF treatment for children with caries and (1) sociodemographic and acculturation characteristics of caregivers and (2) clinical assessments of the children by dentists. METHODS: A caregiver survey collected information on: sociodemographic characteristics; acculturation characteristics, measured using the validated Short Acculturation Scale for Hispanics (SASH); perceived benefits and barriers of SDF treatment, including caregiver comfort; and perceived health-related knowledge. Chart reviews were conducted to assess: the medical / dental insurance of pediatric patients; cumulative caries experience, measured using decayed, missing, filled teeth total scores (dmft / DMFT); whether operating room treatment was needed; and a record of caregiver acceptance of SDF treatment (the outcome measure). Standard logistic regression models were developed for caregiver acceptance of SDF treatment for their children as the binary outcome of interest (yes / no) to calculate unadjusted odds ratios (OR) and adjusted ORs for covariates of interest. RESULTS: Overall, 434 of 546 caregivers (79.5%) accepted SDF treatment for their children. A U-shaped relationship between caregiver odds of accepting SDF treatment and age group of pediatric patients was present, where caregivers were most likely to accept SDF treatment for their children who were either < 6 years or 9-14 years, and least likely to accept SDF treatment for children 6 to < 9 years. The relationship between acculturation and caregiver acceptance of SDF treatment depended upon whether or not caregivers were born in the United States: greater acculturation was associated with caregiver acceptance of SDF treatment among caregivers born in this country, and lower acculturation was associated with caregiver acceptance of SDF treatment among caregivers born elsewhere. CONCLUSIONS: Caregiver acceptance of SDF treatment is high; child's age and caregiver comfort are associated with acceptance. Providers need to communicate the risks and benefits of evidence-based dental treatments to increasingly diverse caregiver and patient populations.

Knowledge and behaviours related to oral health among underserved older adults.

OBJECTIVE: To examine the mouth and body knowledge, beliefs and behaviours of Dominican, Puerto Rican and African American older adults, and their relationships to oral and general health and health care. BACKGROUND: In his seminal framework, Handwerker posited that the norms, attitudes and behaviours related to the experience of disease and treatment reflect where patients live and have lived and are seeking and have sought care, along with their webs of social and health relations. This framework guides the analysis for the present study, wherein qualitative data are used to understand mouth and body knowledge, beliefs and behaviours among racial/ethnic minority older adults, ie, why individuals do what they do and what it means to them. MATERIALS AND METHODS: Focus groups were conducted in Spanish or English with 194 racial/ethnic minority older adults living in northern Manhattan who participated in one of 24 focus group sessions about improving oral health. All groups were digitally audio-recorded, transcribed and translated into English from Spanish, where apt. Analysis involved the classification of evidence from all datasets, organised to identify patterns and relationships. RESULTS: Four themes were manifest in the data regarding cultural understandings of the mouth, the body and health: (a) the ageing mouth and its components; (b) the mouth in relation to the body, health and disease; (c) social meanings of the mouth; and (d) care of the ageing mouth. CONCLUSION: Underserved older adults from diverse cultural backgrounds understand the importance of their mouths to both their overall health and social lives.

Using focus groups to design systems science models that promote oral health equity.

BACKGROUND: While the US population overall has experienced improvements in oral health over the past 60 years, oral diseases remain among the most common chronic conditions across the life course. Further, lack of access to oral health care contributes to profound and enduring oral health inequities worldwide. Vulnerable and underserved populations who commonly lack access to oral health care include racial/ethnic minority older adults living in urban environments. The aim of this study was to use a systematic approach to explicate cause and effect relationships in creating a causal map, a type of concept map in which the links between nodes represent causality or influence. METHODS: To improve our mental models of the real world and devise strategies to promote oral health equity, methods including system dynamics, agent-based modeling, geographic information science, and social network simulation have been leveraged by the research team. The practice of systems science modeling is situated amidst an ongoing modeling process of observing the real world, formulating mental models of how it works, setting decision rules to guide behavior, and from these heuristics, making decisions that in turn affect the state of the real world. Qualitative data were obtained from focus groups conducted with community-dwelling older adults who self-identify as African American, Dominican, or Puerto Rican to elicit their lived experiences in accessing oral health care in their northern Manhattan neighborhoods. RESULTS: The findings of this study support the multi-dimensional and multi-level perspective of access to oral health care and affirm a theorized discrepancy in fit between available dental providers and patients. The lack of information about oral health at the community level may be compromising the use and quality of oral health care among racial/ethnic minority older adults. CONCLUSIONS: Well-informed community members may fill critical roles in oral health promotion, as they are viewed as highly credible sources of information and recommendations for dental providers. The next phase of this research will involve incorporating the knowledge gained from this study into simulation models that will be used to explore alternative paths toward improving oral health and health care for racial/ethnic minority older adults.

Modeling Accessibility of Screening and Treatment Facilities for Older Adults using Transportation Networks.

Increased lifespans and population growth have resulted in an older U.S. society that must reckon with the complex oral health needs that arise as adults age. Understanding accessibility to screening and treatment facilities for older adults is necessary in order to provide them with preventive and restorative services. This study uses an agent-based model to examine the accessibility of screening and treatment facilities via transportation networks for older adults living in the neighborhoods of northern Manhattan, New York City. Older adults are simulated as socioeconomically distinct agents who move along a GIS-based transportation network using transportation modes that mediate their access to screening and treatment facilities. This simulation model includes four types of mobile agents as a simplifying assumption: walk, by car, by bus, or by van (i.e., a form of transportation assistance for older adults). These mobile agents follow particular routes: older adults who travel by car, bus, and van follow street roads, whereas pedestrians follow walkways. The model enables the user to focus on one neighborhood at a time for analysis. The spatial dimension of an older adult's accessibility to screening and treatment facilities is simulated through the travel costs (indicated by travel time or distance) incurred in the GIS-based model environment, where lower travel costs to screening and treatment facilities imply better access. This model provides a framework for representing health-seeking behavior that is contextualized by a transportation network in a GIS environment.

Modeling the Influence of Social Ties and Transportation Choice on Access to Oral Healthcare for Older Adults.

The current U.S. demographic shift toward an older population and the importance of intervening before conditions become severe warrant a concerted effort to ease the burden of access to healthcare for older adults. With regard to oral healthcare, more integrated services for older adults are needed to effectively serve their complex medical and dental needs. Using an agent-based simulation model, this paper examines the influence of social ties and transportation mode choices on opportunities for older adults to participate in community-based preventive screening events and access needed oral healthcare. This approach accounts for the heterogeneity of behavior that arises for a population exhibiting diversity in terms of social factors, including socioeconomic means and social support. In the context of older adults living in urban environments, the availability of different transportation modes ought to be taken into consideration. To explore alternative scenarios for the accessibility of preventive screening events offered at senior centers in northern Manhattan, an agent-based model (ABM) was created with a geographic information system (GIS) to simulate the influence of social ties and transportation choices on older adults seeking preventive screening services and oral healthcare. Results of simulation experiments indicate preferences for public transportation and inequities in accessibility that may be mitigated with social support. This simulation model offers a way to explore social support as an important factor in making transportation mode choices that mediate oral healthcare accessibility and thus oral health outcomes for older adults.

Oral Health Care Receipt and Self-Rated Oral Health for Diverse Asian American Subgroups in New York City.

OBJECTIVES: To identify determinants of receipt of annual oral health examinations and self-rated oral health among diverse Asian American subgroups. METHODS: We used data from the Community Health Resources and Needs Assessment, a community-based survey of Asian American immigrant adults conducted in the New York City metropolitan region from 2013 to 2016 (n = 1288). We used multivariable logistic regression models to assess determinants of oral health care receipt and self-rated oral health. RESULTS: Failure to receive an annual oral health examination was common in this sample (41.5%) and was more frequent for participants who were younger and male and those who had poorer English fluency and lower educational attainment. Not having dental insurance versus having private dental insurance resulted in 2 to 3 times the odds of nonreceipt of oral health care and poor self-rated oral health. CONCLUSIONS: Nonreceipt of annual oral health examinations and poor self-rated oral health were common across Asian American subgroups. Facilitating dental insurance sign-up and providing in-language services may improve oral health care access and ultimately oral health among Asian American immigrants.

Racial/Ethnic Minority Older Adults' Perspectives on Proposed Medicaid Reforms' Effects on Dental Care Access.

To examine how proposed Medicaid reform plans are experienced by racial/ethnic minority older adults and what the implications are for their ability to access dental care through Medicaid, from 2013 to 2015 we conducted focus groups in northern Manhattan, New York, New York, among African American, Dominican, and Puerto Rican adults aged 50 years and older. Participants reported problems with affording copayments for care, complicated health and social issues, the need for vision and dental care close to home, and confusion about and stigmatization with Medicaid coverage. Federal, state, and local public health agencies can help by clarifying and simplifying Medicaid plans and sustaining benefits that older adults need to live healthy and dignified lives.

Recruitment of racial/ethnic minority older adults through community sites for focus group discussions.

BACKGROUND: Despite a body of evidence on racial/ethnic minority enrollment and retention in research, literature specifically focused on recruiting racially/ethnically diverse older adults for social science studies is limited. There is a need for more rigorous research on methodological issues and the efficacy of recruitment methods. Cultural obstacles to recruitment of racial/ethnic minority older adults include language barriers, lack of cultural sensitivity of target communities on the part of researchers, and culturally inappropriate assessment tools. METHODS: Guided by the Consolidated Framework for Implementation Research (CFIR), this study critically appraised the recruitment of racial/ethnic minority older adults for focus groups. The initial approach involved using the physical and social infrastructure of the ElderSmile network, a community-based initiative to promote oral and general health and conduct health screenings in places where older adults gather, to recruit racial/ethnic minority adults for a social science component of an interdisciplinary initiative. The process involved planning a recruitment strategy, engaging the individuals involved in its implementation (opinion leaders in senior centers, program staff as implementation leaders, senior community-based colleagues as champions, and motivated center directors as change agents), executing the recruitment plan, and reflecting on the process of implementation. RESULTS: While the recruitment phase of the study was delayed by 6 months to allow for ongoing recruitment and filling of focus group slots, the flexibility of the recruitment plan, the expertise of the research team members, the perseverance of the recruitment staff, and the cultivation of change agents ultimately resulted in meeting the study targets for enrollment in terms of both numbers of focus group discussions (n = 24) and numbers of participants (n = 194). CONCLUSIONS: This study adds to the literature in two important ways. First, we leveraged the social and physical infrastructure of an existing program to recruit participants through community sites where older adults gather. Second, we used the CFIR to guide the appraisal of the recruitment process, which underscored important considerations for both reaching and engaging this underserved population. This was especially true in terms of understanding the disparate roles of the individuals involved in implementing and facilitating the recruitment plan.

Estimating peer density effects on oral health for community-based older adults.

BACKGROUND: As part of a long-standing line of research regarding how peer density affects health, researchers have sought to understand the multifaceted ways that the density of contemporaries living and interacting in proximity to one another influence social networks and knowledge diffusion, and subsequently health and well-being. This study examined peer density effects on oral health for racial/ethnic minority older adults living in northern Manhattan and the Bronx, New York, NY. METHODS: Peer age-group density was estimated by smoothing US Census data with 4 kernel bandwidths ranging from 0.25 to 1.50 mile. Logistic regression models were developed using these spatial measures and data from the ElderSmile oral and general health screening program that serves predominantly racial/ethnic minority older adults at community centers in northern Manhattan and the Bronx. The oral health outcomes modeled as dependent variables were ordinal dentition status and binary self-rated oral health. After construction of kernel density surfaces and multiple imputation of missing data, logistic regression analyses were performed to estimate the effects of peer density and other sociodemographic characteristics on the oral health outcomes of dentition status and self-rated oral health. RESULTS: Overall, higher peer density was associated with better oral health for older adults when estimated using smaller bandwidths (0.25 and 0.50 mile). That is, statistically significant relationships (p < 0.01) between peer density and improved dentition status were found when peer density was measured assuming a more local social network. As with dentition status, a positive significant association was found between peer density and fair or better self-rated oral health when peer density was measured assuming a more local social network. CONCLUSIONS: This study provides novel evidence that the oral health of community-based older adults is affected by peer density in an urban environment. To the extent that peer density signifies the potential for social interaction and support, the positive significant effects of peer density on improved oral health point to the importance of place in promoting social interaction as a component of healthy aging. Proximity to peers and their knowledge of local resources may facilitate utilization of community-based oral health care.

Third Places for Health Promotion with Older Adults: Using the Consolidated Framework for Implementation Research to Enhance Program Implementation and Evaluation.

This study extends the concept of third places to include community sites where older adults gather, often for meals or companionship. The Consolidated Framework for Implementation Research guided program implementation and evaluation. Depending upon health promotion program needs, the physical infrastructure of a site is important, but a supportive director (champion) can often overcome identified deficits. Senior centers may be locally classified into four types based upon eligibility requirements of residents in affiliated housing and services offered. Participants who attend these centers differ in important ways across types by most sociodemographic as well as certain health and health care characteristics.

Enhancing implementation science by applying best principles of systems science.

BACKGROUND: Implementation science holds promise for better ensuring that research is translated into evidence-based policy and practice, but interventions often fail or even worsen the problems they are intended to solve due to a lack of understanding of real world structures and dynamic complexity. While systems science alone cannot possibly solve the major challenges in public health, systems-based approaches may contribute to changing the language and methods for conceptualising and acting within complex systems. The overarching goal of this paper is to improve the modelling used in dissemination and implementation research by applying best principles of systems science. DISCUSSION: Best principles, as distinct from the more customary term 'best practices', are used to underscore the need to extract the core issues from the context in which they are embedded in order to better ensure that they are transferable across settings. Toward meaningfully grappling with the complex and challenging problems faced in adopting and integrating evidence-based health interventions and changing practice patterns within specific settings, we propose and illustrate four best principles derived from our systems science experience: (1) model the problem, not the system; (2) pay attention to what is important, not just what is quantifiable; (3) leverage the utility of models as boundary objects; and (4) adopt a portfolio approach to model building. To improve our mental models of the real world, system scientists have created methodologies such as system dynamics, agent-based modelling, geographic information science and social network simulation. To understand dynamic complexity, we need the ability to simulate. Otherwise, our understanding will be limited. The practice of dynamic systems modelling, as discussed herein, is the art and science of linking system structure to behaviour for the purpose of changing structure to improve behaviour. A useful computer model creates a knowledge repository and a virtual library for internally consistent exploration of alternative assumptions. CONCLUSION: Among the benefits of systems modelling are iterative practice, participatory potential and possibility thinking. We trust that the best principles proposed here will resonate with implementation scientists; applying them to the modelling process may abet the translation of research into effective policy and practice.

The Oral Health Care Manager in a Patient-Centered Health Facility.

UNLABELLED: The dental hygienist team member has an opportunity to coordinate care within an interprofessional practice as an oral health care manager. BACKGROUND AND PURPOSE: Although dental hygienists are currently practicing within interprofessional teams in settings such as pediatric offices, hospitals, nursing homes, schools, and federally qualified health centers, they often still assume traditional responsibilities rather than practicing to the full extent of their training and licenses. This article explains the opportunity for the dental hygiene professional to embrace patient-centered care as an oral health care manager who can facilitate integration of oral and primary care in a variety of health care settings. METHODS: Based on an innovative model of collaboration between a college of dentistry and a college of nursing, an idea emerged among several faculty members for a new management method for realizing continuity and coordination of comprehensive patient care. Involved faculty members began working on the development of an approach to interprofessional practice with the dental hygienist serving as an oral health care manager who would address both oral health care and a patient's related primary care issues through appropriate referrals and follow-up. This approach is explained in this article, along with the results of several pilot studies that begin to evaluate the feasibility of a dental hygienist as an oral health care manager. CONCLUSION: A health care provider with management skills and leadership qualities is required to coordinate the interprofessional provision of comprehensive health care. The dental hygienist has the opportunity to lead closer integration of oral and primary care as an oral health care manager, by coordinating the team of providers needed to implement comprehensive, patient-centered care.

The ElderSmile TimeMap: Benefits of Connecting Statistics With Time and Place.

Community-based programs are critical for locally targeted public health education and accessible service delivery. Deriving useful information from such programs is important for their own evaluation and improvement and may facilitate research collaboration with partners and experts. Here we present an interactive Web-based application designed for a community-based oral health outreach program called ElderSmile to demonstrate how data can be summarized, filtered, compared, and visualized by time and place to inform program planning, evaluation, and research. The ElderSmile TimeMap ( http://www.acsu.buffalo.edu/∼smetcalf/resources/timemap.html ) is an emergent product of a US National Institutes of Health-funded collaboration of knowledge sharing among multidisciplinary team members at the University at Buffalo, Columbia University, and New York University.

A community-based oral public health approach to promote health equity.

OBJECTIVES: We explored the interrelationships among diabetes, hypertension, and missing teeth among underserved racial/ethnic minority elders. METHODS: Self-reported sociodemographic characteristics and information about health and health care were provided by community-dwelling ElderSmile participants, aged 50 years and older, who took part in community-based oral health education and completed a screening questionnaire at senior centers in Manhattan, New York, from 2010 to 2012. RESULTS: Multivariable models (both binary and ordinal logistic regression) were consistent, in that both older age and Medicaid coverage were important covariates when self-reported diabetes and self-reported hypertension were included, along with an interaction term between self-reported diabetes and self-reported hypertension. CONCLUSIONS: An oral public health approach conceptualized as the intersection of 3 domains-dentistry, medicine, and public health-might prove useful in place-based assessment and delivery of services to underserved older adults. Further, an ordinal logit model that considers levels of missing teeth might allow for more informative and interpretable results than a binary logit model.

Evidence From ElderSmile for Diabetes and Hypertension Screening in Oral Health Programs.

The ElderSmile clinical program was initiated in northern Manhattan in 2006. ElderSmile is a comprehensive community-based program offering education, screening and treatment services for seniors in impoverished communities. Originally focused on oral health, ElderSmile was expanded in 2010 to include diabetes and hypertension education and screening. More than 1,000 elders have participated in the expanded program to date. Quantitative and qualitative findings support a role for dental professionals in screening for these primary care sensitive conditions.

The Impact of Medicaid Expansion on Oral Health Equity for Older Adults: A Systems Perspective.

This paper uses a collaborative, interdisciplinary systems science inquiry to explore implications of Medicaid expansion on achieving oral health equity for older adults. Through an iterative modeling process oriented toward the experiences of both patients and oral health care providers, complex feedback mechanisms for promoting oral health equity are articulated that acknowledge the potential for stigma as well as disparities in oral health care accessibility. Multiple factors mediate the impact of Medicaid expansion on oral health equity.

Toward Implementing Primary Care at Chairside: Developing a Clinical Decision Support System for Dental Hygienists.

INTRODUCTION: The goal of this project was to use the Consolidated Framework for Implementation Research (CFIR) as the theoretical foundation for developing a web-based clinical decision support system (CDSS) for primary care screening and care coordination by dental hygienists at chairside. METHODS: First, we appraised New York State education and scope of practice requirements for dental hygienists with input from health experts who constituted a Senior Advisory Board for the project, and reviewed current professional guidelines and best practices for tobacco use, hypertension and diabetes screening, and nutrition counseling at chairside. Second, we created algorithms for these four health issues (tobacco, hypertension, diabetes, and nutrition) using evidence-based guidelines endorsed by authoritative professional bodies. Third, an information technology specialist incorporated the algorithms into a tool using an iterative process to refine the CDSS, with input from dental hygienists, dentists, Senior Advisory Board members and research staff. RESULTS: An evidence-based CDSS for use by dental hygienists at chairside for tobacco use, hypertension and diabetes screening, and nutrition counseling was developed with the active participation of the individuals involved in the implementation process. CONCLUSIONS: CDSS technology may potentially be leveraged to enhance primary care screening and coordination by dental hygienists at chairside, leading to improved patient care. Using the CFIR as a pragmatic structure for implementing this intervention across multiple settings, the developed CDSS is available for downloading and adaptation to diverse dental settings and other primary care sensitive conditions.
