Year 5 Projects
Consumer Survey Focused on Parents’ Experiences Accessing Oral Health Care Services for Their Children
Despite efforts to improve access to oral health services in the US, oral health disparities persist for many vulnerable population groups, including children. Children are especially vulnerable to not receiving health or oral health services because they are dependent on others to arrange appointments and provide transportation to services. Researchers at the OHWRC will collaborate with the Health Workforce Research Center at the Association of American Medical Colleges (AAMC) to survey parents about the factors that affect access to oral health services for their children. This research highlights unique access barriers for specific high-need children (racial/ethnic minorities, low-income parents, uninsured families, Medicaid beneficiaries, rural individuals) or geographic regions. This research resulted in a Report.
Compendium of Innovations in Oral Health Service Delivery
Oral health providers are using a variety of innovative strategies to expand access to oral health services in community-based settings, including federally qualified health centers, schools and nursing homes, among others. This compilation summarizes best practices in innovative oral health service delivery programs drawn from over 40 case studies conducted by the Oral Health Workforce Research Center (OHWRC). Each summary is presented in a standard 2-page format highlighting key program elements, with special attention to the organizations’ workforce strategies that have successfully expanded access to care for underserved populations. This research resulted in the Compendium.
Year 4 Projects
Impacts of Dental Post-Graduate Residency Training on Choice of Practice Setting
Post-graduate dental training programs result in quantifiable numbers of graduates and services to rural, underserved and vulnerable patients during training, and measurable programmatic capacity of the training to address community needs, but little is known about the longer term impact of the federal investment in these programs. Researchers at the OHWRC surveyed over 500 graduates of one such program to establish the impact of this investment. This research resulted in a Report, Policy Brief, and Abstract.
A National Study of the Practice Characteristics of Women in Dentistry and Potential Impacts on Access to Care for Underserved Communities
Demographic changes within the dental profession including aging and gender distribution are affecting dental practice characteristics and practice locations. For this study, OHWRC collaborated with the American Dental Association (ADA) to conduct secondary data analyses to assess the impact of demographic changes in dentistry on access to oral health services, particularly in rural areas and for underserved populations. This research resulted in a Report, Policy Brief, and Abstract.
Conducting a Consumer Survey Focused on Barriers and Facilitators of Access to Oral Health Services
Despite efforts over the past decade to improve access to oral health services in the US, oral health disparities persist for many high need populations. To better understand the factors that contribute to these disparities from the patient perspective, OHWRC partnered with the Workforce Studies unit at the Association of American Medical Colleges (AAMC) to include a series of questions on oral health care access in AAMC’s biannual Consumer Survey of Health Care Access. This research resulted in a Report, Policy Brief, and Abstract.
Conducting a Series of Case Studies to Identify Strategies Used by Federally Qualified Health Centers to Integrate Oral Health and Substance Abuse/Behavioral Health Services
There is growing recognition of the relationship between mental illness and behavioral health disorders with oral and physical health status. Safety net provider organizations are key to providing integrated care for many of their patients with mental health or substance use disorders. OHWRC conducted 6 case studies of Federally Qualified Health Centers or other safety net providers that have successfully integrated oral health and substance abuse/behavioral health services. This research resulted in a Report, Policy Brief, and Abstract.
Year 3 Projects
Trends in the Provision of Oral Health Services by FQHCs
Federally qualified health centers (FQHCs) are increasingly providing oral health services directly to patients in fixed clinics and mobile and portable oral health programs. However, some continue to offer only referrals or vouchers for services from community dentists. This study examined factors that might impact the decision of an FQHC to provide oral health services directly, including state Medicaid and reimbursement policies for oral health. The study used a variety of data sources including HRSA’s Uniform Data System and primary data. This research resulted in a Report, Policy Brief, and Abstract.
Exploring the Impact of a Teledentistry Program on Access to Services and Oral Health Outcomes in the Patient Population
In Year 2, the OHWRC conducted a series of case studies on the use of teledentistry applications in the delivery of oral health services. One of the FQHCs included in the research study, was an early innovator in teledentistry and has indicated a willingness to provide patient utilization data to better understand the impacts of the teledentistry program on access to care and oral health outcomes. The analysis of these data by OHWRC researchers will highlight the value of teledentistry applications, particularly for safety net providers and underserved populations. This research resulted in an article that was submitted to a peer-reviewed publication.
Assessing the Impact of DH Scope of Practice on Oral Health Outcomes
In Year 2, the OWHRC completed a study to update the state-specific Dental Hygiene Professional Practice Index (DHPPI) scores to reflect current dental hygiene scope of practice in 2016. The variables in the 2016 DHPPI were factor analyzed to determine validity. This project will use the 2016 data in multi-level regression analysis to examine the impact of state level scope of practice on oral health outcomes for low-income children. This research resulted in an article that was submitted to a peer-reviewed publication.
The Evolving Pipeline of Hispanic Dentists in the US
The Hispanic/Latino (H/L) dentist population is disproportionately small compared to the rapidly growing and historically underserved H/L population in the US, and current enrollment will not meet the demand. Half of the H/L dentists in the US are foreign-born, and about 1 in 5 were trained outside the US. Changing licensure laws have limited the pathways for non US-trained providers. Using a nationally representative sample survey of H/L dentists and a policy review, this study elucidates trends and challenges in H/L dentists’ pathways to practice, examines the changing patterns of care delivery, and identifies access and care delivery goals for the H/L population. This research resulted in a Report, Policy Brief, and Abstract.
An Assessment of Mobile and Portable Dentistry Programs to Improve Population Oral Health: Practice and Policy Implications
Mobile and portable oral health service programs continue to gain the attention of policymakers and providers for their ability to bring oral health services into local communities and to reach patients with limited access to oral health services. This study consists of 7 case studies that describe the workforce in mobile dentistry programs, the structure and funding of programs, and the regulation of mobile and portable dentistry by states. This research resulted in a Report, Policy Brief, and Abstract.
Trends in the Development of the Dental Service Organization Model: Implications for the Oral Health Workforce and Access to Services
The fastest growing segment of the dental delivery system is Dental Service Organizations (DSOs). While DSOs take various forms, as large employers of dental providers, they are changing the landscape of oral health care delivery. OHWRC conducted a survey of a convenience sample of DSOs and compiled case studies of 6 dental support organizations delivering general or specialty dental services to patients. This mixed-methods study examined the variety of DSO models, who they serve, their workforce needs and practices, career pathways provided, and evolving models of workforce deployment. This research resulted in a Report, Policy Brief, and Abstract.
Developing a Graphic Visualization to Help Policy Makers Understand the Wide Variation in State-level Dental Hygiene Scope of Practice
There is substantial variation in dental hygiene (DH) scope of practice across states, but no user-friendly tools to help policymakers understand these differences. OHWRC produced an infographic on state-specific DH scope of practice. Researchers worked with key stakeholders in dental hygiene (representing education, practice, and research) to identify the variables to include in the graphic to accurately depict key DH responsibilities associated with scope of practice and to display state-to-state variation. This research resulted in an Infographic.
Further Study of State-Level Policies that Affect Access to Dental Services in LTC Settings
A Year 1 OHWRC project included a 4-state case study of delivery models for dental care services in long-term care (LTC) settings. Since then, a more comprehensive literature review was completed and additional information was compiled on key state-level policy factors that drive the organizational models cited in the study. OHWRC researchers conducted an in-depth analysis of policy factors that serve as barriers to and facilitators of access to dental services in long term care settings. Findings highlighted state level policy factors that influence access to needed services. This research resulted in an article that was submitted to a peer-reviewed publication.
Generating State and Sub-State Maps of Oral Health Training Sites, Substance Abuse Treatment Centers, and FQHCs and Look-alike Clinics that Provide Comprehensive Oral Health Services
Researchers at the OHWRC used data and information provided by HRSA and the Substance Abuse and Mental Health Services Administration (SAMHSA) to produce a series of maps depicting the following: (1) oral health training and rotation sites, (2) substance abuse treatment centers, and (3) FQHCs and FQHC look-alike clinics (FQHC-LA) that provide comprehensive dental services. These maps integrated information on oral health and substance abuse treatment centers which could potentially encourage possible synergies and resource sharing.
Year 2 Projects
Determinants of Oral Health Assessment and Screening in Physician Assistant Clinical Practice
In 2013, a survey of directors of physician assistant education programs conducted by the Center for Health Workforce Studies (CHWS) found that more than 70% of respondent programs had integrated oral health topics into core content of their physician assistant (PA) curriculum. A 2014 HRSA-sponsored report described core oral health clinical competencies for frontline primary care clinicians, including PAs, and outlined strategies for implementing oral health training in primary care practice and safety net settings. However, whether training in oral health in PA education programs translates to actual screening and assessment of patients’ oral health status in clinical practice remains unclear. OHWRC in cooperation with the American Association of Physician Assistants (AAPA) fielded a survey to a sample of PAs across the US in 2016 to ascertain PA practice characteristics, to describe oral health screening activities for patients, to understand the extent and source of PA education in oral health, and to determine facilitators and barriers to the integration of oral health service in practice. This research resulted in a Report, Policy Brief, and Abstract.
Understanding the Impact of Dental Residents and Student Externs on Oral Health Service Delivery Capacity in the Safety Net
Demand for dental residency and dental student externship opportunities has grown in recent years, driven by the economy for dental employment and the desire of students for increased market competitiveness. In addition to specialty residencies, some states now also require that general dentists complete a year of advanced education in general dentistry before licensure. The Teaching Health Center program, a feature of the ACA, has contributed to increased capacity in dental residency programs, has impacted new dentist preparedness for practice, has increased opportunities for recruitment and retention of dentists in community clinics, and has increased access to oral health services for safety net populations. OHWRC examined trends in demand for advanced training by students and how this aligns with current policy supporting this training and practice. Researchers also explored the impact of residencies in ambulatory care settings, particularly for FQHCs, on service capacity and access for patients. This research resulted in a Report, Policy Brief, and Abstract.
Case Studies of 6 Innovative Oral Health Service Delivery Programs Using Teledentistry
Teledentistry is an emerging strategy with the potential to improve oral health outcomes for underserved populations, particularly those living in rural communities. OHWRC conducted 6 case studies of innovative oral health programs in different states that employed teledentistry. The case studies entailed site visits and in-depth interviews with both administrative, HIT, and clinical staff at selected sites where teledentistry services are provided. In addition, OHWRC reviewed current state statutes and regulations in dentistry with a specific focus on regulation of teledentistry and state-level reimbursement policies for oral health providers accepting Medicaid and/or commercial insurance for services provided using teledentistry. The findings provide a better understanding of teledentistry program applications, workforce strategies, impacts on access to care, the organizational structure in which services are provided, and the barriers and facilitators of teledentistry services. This research resulted in a Report, Policy Brief, and Abstract.
Development of a New Scope of Practice Index for Dental Hygienists
As part of its Year 1 research projects, staff at OHWRC conducted an extensive review of state legislation and regulation governing registered dental hygienists in order to describe the current regulatory environment and quantify it using the 2001 dental hygiene professional practice index (DHPPI). However, much has changed for the dental hygiene profession in the decade since the DHPPI was constructed and the utility of the 2001 DHPPI for analysis had diminished. In 2016, OHWRC updated and modified the DHPPI scale by adding new variables to better quantify current practice for dental hygienists and allow comparisons of change over time for dental hygiene practice in each state. This research resulted in a Report, Policy Brief, and Abstract.
Underrepresented Minority Dentists’ Contribution to Health Equity in the US
Black, Hispanic, and American Indian/Alaska Native dentists are substantially underrepresented relative to their proportion in the general population. HRSA has a strong commitment to improve health workforce diversity. OHWRC examined nationally representative sample survey data of underrepresented minority (URM) dentists in the US to determine the supply, distribution, and practice patterns of URM dentists, current contributions to dental care for minority populations, and future supply and impact on the access to care for minority populations based on cohort practice patterns and projected inflows through US schools as well as immigration flows over time. This research resulted in an Article published in Health Affairs, a Policy Brief, and Abstract.
Year 1 Projects
A Comparison of Medicaid Dental Claims Data in 2 States With Different Adult Dental Benefits, 2012-2013
OHWRC conducted a comparative analysis of Medicaid dental claims over a 2-year period in New York and Oklahoma. Oklahoma Medicaid provides only a limited dental benefit for adult enrollees 21 years of age and older, including emergency exams and extractions of diseased teeth. In contrast, adult Medicaid beneficiaries in New York State have a comprehensive dental benefit that includes preventive services, restorative services, periodontal services, dentures, and oral surgery services. The objective of this research was to understand the impact of Medicaid dental benefits and availability of providers on utilization of dental services. This research resulted in:
- A Comparison Report, Policy Brief, and Abstract;
- A Oklahoma-specific Report, Policy Brief, and Abstract; and
- A New York-specific Report, Policy Brief, and Abstract
Updating the Professional Practice Index for Dental Hygienists in the 50 US States and the District of Columbia
OHWRC updated the scope of practice index for registered dental hygienists (RDHs) that was originally created in 2001. Researchers provided an objective quantification of current practices for RDHs and a comparison of changes over time for dental hygiene practice in each state of the US. This research resulted in a Report, Policy Brief, Abstract, and an Article published in Health Affairs.
Case Studies of Oral Health Service Delivery Models Used in Long-Term Care Settings
OHWRC examined the current and changing practice models utilized in providing dental services in long-term care, residential care, and for homebound individuals through 4 state case studies. A secondary objective was to determine policy variables that may impact the availability of these services within a state or community and describe these impacts. This research resulted in a Report, Policy Brief, and Abstract.
A Study of the Dental Assistant Workforce in the United States
OHWRC conducted a comprehensive examination of the dental assisting profession to understand the contributions of dental assistants to oral health services. Researchers examined demographic and educational characteristics of dental assistants and identified gaps in data about this workforce that should be addressed.
