Perceived social status, socioeconomic status, and preventive dental utilization among a low-income Medicaid adult population.

OBJECTIVES: Perceived Social Status (PSS) is a measure of cumulative socioeconomic circumstances that takes perceived self-control into account. It is hypothesized to better capture social class compared to socioeconomic status (SES) measures (i.e., education, occupation, and income). This study examined the association between PSS and dental utilization, comparing the strength of associations between dental utilization and PSS and SES measures among a low-income adult Medicaid population. METHODS: A cross-sectional survey was administered to a random sample of low-income adults in Iowa, United States with Medicaid dental insurance (N = 18,000) in the spring of 2018. Respondents were asked about PSS, dental utilization, and demographics. A set of multivariable logistic regression models examined the relative effects of PSS and SES measures on dental utilization, controlling for age, sex, health literacy, whether the respondent was aware they had dental insurance, transportation, and perceived need of dental care. RESULTS: The adjusted response rate was 25%, with a final sample size of 2252. Mean PSS (range 1-10) was 5.3 (SD 1.9). PSS was significantly associated with dental utilization (OR = 1.11; CI = 1.05, 1.18) when adjusting for control variables, whereas other SES measures-education, employment, and income-were not. CONCLUSIONS: PSS demonstrated a small positive association with dental utilization. Results support the relative importance of PSS, in addition to SES measures, as PSS may capture aspects of social class that SES measures do not. Results suggest the need for future research to consider the effects of PSS on oral health outcomes and behaviors.

Dentist-reported differences in services provided to patients with public vs. private dental insurance.

INTRODUCTION: Variation in dentists' provision of types of dental services based on patients' insurance may impact population access to comprehensive care. The aim of this study was to describe differences in the types of services provided to adult patients with Medicaid versus private insurance among private practice general dentists. METHODS: The data source was a 2019 survey of private practice dentists in Iowa, and the study sample included general dentists with current or recent participation in Iowa's Medicaid program for adults (n = 264). Bivariate analyses were used to compare differences in the types of services provided to privately insured and publicly insured patients. RESULTS: Dentists reported the greatest differences in services provided to patients with public versus private insurance for prosthodontic procedures, including complete dentures, removable partial dentures, and crown and bridge services. Endodontic services were the least frequently provided category of services provided by dentists for both patient groups. Patterns were generally similar among both urban and rural providers. CONCLUSION: Access to dental care for Medicaid members should be evaluated not only on the proportion of dentists who see new Medicaid patients but also on the types of services dentists provide to this population.

Testing dental quality measures: Emergency department visits for nontraumatic dental conditions and subsequent follow-up dental visits.

BACKGROUND: The goal of this study was to test the feasibility, reliability, and validity of the Dental Quality Alliance's adult dental quality measures for system-level implementation for ambulatory care sensitive (ACS) emergency department (ED) visits for nontraumatic dental conditions (NTDCs) in adults and follow-up after ED visits for NTDCs in adults. METHODS: Medicaid enrollment and claims data from Oregon and Iowa were used for measure testing. Testing included validation of diagnosis codes in claims data through patient record reviews of ED visits and calculations of κ statistic, sensitivity, and specificity. RESULTS: Adult Medicaid enrollees' ACS NTDC ED visits ranged from 209 through 310 per 100,000 member-months. In both states, patients in the age category 25 through 34 years and non-Hispanic Black patients had the highest rates of ACS ED visits for NTDCs. Only one-third of all ED visits were associated with a follow-up dental visit within 30 days, decreasing to approximately one-fifth with a 7-day follow-up. The agreement between the claims data and patient records for identification of ACS ED visits for NTDCs was 93%, κ statistic was 0.85, sensitivity was 92%, and specificity was 94%. CONCLUSIONS: Testing revealed the feasibility, reliability, and validity of 2 DQA quality measures. Most beneficiaries did not have a follow-up with a dentist within 30 days of an ED visit. PRACTICAL IMPLICATIONS: Adoption of quality measures by state Medicaid programs and other integrated care systems will enable active tracking of beneficiaries with ED visits for NTDCs and develop strategies to connect them to dental homes.

Engaging new partners in human papillomavirus (HPV) vaccine promotion: Considerations for training private practice dental professionals in HPV vaccine promotion.

OBJECTIVES: With rates of the human papillomavirus (HPV) vaccination remaining low and rates of oropharyngeal cancer rising, engaging new partners to promote vaccination is necessary. We aimed to identify dental hygienists' and dentists' knowledge about HPV, the HPV vaccine, and preferences for continuing education. METHODS: This mixed-methods study recruited dental hygienists and dentists working in private practice in Iowa to participate in a mailed cross-sectional survey (dental hygienists) and qualitative telephone interviews (dental hygienists and dentists). Survey and interview topics included existing knowledge about HPV vaccination, HPV vaccination promotion efforts, barriers to HPV vaccine promotion, and preferences for continuing education (CE). RESULTS: We received 470 surveys from dental hygienists (response rate = 22.6%) and interviewed 19 dental hygienists and 20 dentists. Vaccine efficacy and safety, along with communication strategies, were key topics of interest for CE. Dental hygienists' most commonly identified barriers were lack of knowledge (67%) and low comfort levels (42%). CONCLUSIONS: Knowledge was identified as a key barrier to providing a strong recommendation for HPV vaccination and convenience was the most important factor to consider for any future CE. Our team is in the process of designing a CE course based on this information to help dental professionals effectively engage in HPV vaccine promotion in their practices.

Introducing dental students to dental public health: An analysis of US predoctoral course syllabi.

Dental public health competencies in predoctoral dental education ensure that students have the skills to succeed in an increasingly complex professional environment. This study examined existing public health curricula in US dental education and their alignment with national recommendations from the American Association of Public Health Dentistry (AAPHD) and guidance from the Healthy People Curriculum Task Force for health professions education programs. We contacted all US dental schools (N = 66) in November 2020-January 202 and requested syllabi for schools' first course with dental public health content. We received 34 syllabi, which provided textual data for content analysis. The authors used an initial content analysis tool to extract descriptive course characteristics. Then, direct and emergent coding was performed to summarize course content. Direct codes included the 23 dental public health topics specified by AAPHD recommendations. Uncategorized content was coded using an inductive approach to identify emergent course themes. Frequently covered topics included principles of dental public health (79% of syllabi) and access to care (79%). "Health disparities" was the most common emergent theme, with 50% of courses including related content. There was little consistency in how courses approached each topic. For example, the topic "access to care" covered healthcare delivery systems, determinants of health, legislative reform, and advocacy. Dental public health was often taught alongside unrelated content. Recommendations for dental public health competencies should be updated to include new educational priorities, align with current national recommendations, and align with Commission on Dental Accreditation Standards more clearly.

American Board of Dental Public Health diplomate survey, 2021: Competency domains and practice.

OBJECTIVE: To describe current Dental Public Health diplomates and list the competency domains that diplomates considered either essential or optional elements of their practice. METHODS: The American Board of Dental Public Health administered an electronic survey to active and life member diplomates during September 2021. The survey included 101 items in three sections: (1) Education and Work Experience; (2) Dental Public Health Tasks; and (3) Demographics. The Dental Public Health Tasks section asked individuals how essential work-related tasks were to their current practice. Descriptive analyses were conducted using SAS. RESULTS: The overall response rate was 82.6% (157 eligible of 190 returned). Most respondents were women, 35 to 54 years of age, and either non-Hispanic white or non-Hispanic Asian. Twice as many had DDS or DMD degrees than BDS degrees. The vast majority completed a Dental Public Health residency and received masters level training from an accredited program. About three-fourths worked in the United States and held a U.S. license. More than 37% reported a second doctoral degree and 70% worked in academia. Responses to questions about tasks closely aligned with working in academia and less so with positions related to advocacy, regulation, and program evaluation. CONCLUSIONS: Current diplomates are concentrated in academia. If this trend continues, it may be necessary to restructure the competencies, so training and skills acquisition remain timely and relevant. The specialty may also need to encourage future generations to consider non-academic positions so Dental Public Health remains an impactful component of the public health care system.

Dentist attitudes toward an annual benefit maximum in Iowa's adult Medicaid program.

OBJECTIVES: The Dental Wellness Plan (DWP) provides dental coverage for adult Medicaid enrollees in Iowa. In September 2018, a $1000 annual benefit maximum (ABM) was implemented in the DWP program. The aim of this study was to explore private dentists' attitudes toward ABMs and factors associated with ABM attitudes. METHODS: The data source was a mailed survey administered in spring 2019 to all private practice dentists in Iowa. The two dependent variables were (1) attitude toward the $1000 ABM and (2) attitude toward any ABM generally. Independent variables included demographic and practice-related factors, and participation in and attitudes toward the DWP. Descriptive, bivariate, and multivariable analyses were conducted. RESULTS: While over half (56%) of providers reported a positive attitude toward "Any ABM," less than half (40%) reported a positive attitude toward the "$1000 ABM." Attitudes toward both "$1000 ABM" and "Any ABM" were significantly and positively associated with attitudes toward DWP overall and toward DWP structure. Independent variables that were significantly associated with both the "$1000 ABM" and "Any ABM" included overall attitude toward the DWP, attitude toward DWP structure, and practice busyness. CONCLUSIONS: Utilizing an ABM, particularly one set at $1000 for a Medicaid program, elicits mixed attitudes among dentists. Future research should evaluate the impact of Medicaid ABMs on long term dentist participation and patient's ability to receive needed care.

Randomized experiment on the effect of incentives and mailing strategy on response rates in a mail survey of dentists.

OBJECTIVES: Response rates for mail surveys of dentists and other health care providers have declined appreciably over the past several decades. The objective of this study was to update evidence about the impact use of incentives and different mail strategies on response rates in a mail survey of dentists. METHODS: We randomized private practice dentists in Iowa (N = 1267) into six study groups to test the effects of incentives and mail strategy on response rate. Survey incentives included either a $2 bill or a customized pen/stylus; a control group with no incentive was included. Mail strategies included bulk mail or first-class stamps. RESULTS: The overall survey response rate was 43%. A $2 bill incentive was associated with significantly higher likelihood of returning a survey compared to the control group with no incentive (48% response rate vs. 40%, respectively). A non-monetary incentive was not significantly associated with likelihood of response. Use of first-class stamps compared to bulk mail did not significantly affect response rate. CONCLUSIONS: This study demonstrated the effectiveness of a $2 incentive to increase response rate in a mail survey of dentists. Given the background trend of declining survey participation rates, researchers should consider use of monetary incentives and explore new strategies to increase participation among dentists and other health care providers.

Applying "Stages of Readiness to Change" Model to Dentists' Decisions to Participate in Medicaid: An Exploratory Study.

BACKGROUND: The Stages of Readiness to Change (SOC) behavioral model describes behavior change as a process and distinguishes individuals based on their current behavior and readiness to change that behavior. SOC can be used to improve dentists' participation in a state public dental benefit program (Medicaid) by targeting them at different SOC with interventions, strategies, and tools tailored to those stages. Therefore, this study assessed the usefulness of using SOC to describe dentists' attitudes towards and participation in Medicaid. Dentists' participation in Medicaid is of interest to policymakers, and this study demonstrates a method to identify potential opportunities for intervention. METHODS: A modified SOC algorithm used data from a periodic survey of Iowa Dentists to categorize dentists (N=514) into: 1) pre-contemplation, 2) considering participation (SOC contemplation and preparation), 3) acting (SOC action and maintenance), and 4) risk of relapse (at risk for discontinuing participation). The four SOC stages were compared using ANOVA and post hoc Tukey's test among: practice characteristics, Dentists Altruism scale, Attitude about Program Administration scale, Attitude about Medicaid patients scale and Perception of Importance of Medicaid Problems scale. RESULTS: Among survey respondents, 36% were categorized as pre-contemplation, 6% were considering Medicaid participation, 12% were acting as Medicaid providers with minimal risk of relapse, and 46% were participating and at risk of discontinuing. Dentists' attitudes towards program administration, Medicaid patients, and access to care varied across the SOC cycle. CONCLUSION: Nearly, 46% dentists in this analysis were identified as at risk of discontinuing participation - a much larger proportion than dentists considering Medicaid participation. Categorizing dentists using this approach has important implications for programmatic interventions. For example, policymakers targeting our study population could focus their efforts on reducing the likelihood of dentists dropping out of the program, with less emphasis targeting dentists in the precontemplation stage.

A Mixed-Methods Examination of Factors Related to HPV Vaccination Promotion in Private Dental Settings, Iowa, 2019.

INTRODUCTION: Human papillomavirus (HPV)-associated oropharyngeal cancer rates are rising, particularly in males, although rates of other HPV-related cancers are decreasing. Although the HPV vaccine is safe and effective, vaccination rates remain below the Healthy People 2030 goal of 80% coverage. Engaging dental providers, who have experience with patient education and oropharyngeal cancer, may prove useful in efforts to increase vaccination rates. Our research explores dental providers' (dentists, dental hygienists) willingness to participate in continuing education about HPV, educate parents of adolescents, recommend the vaccine for adolescents, and refer parents to medical providers. METHODS: We used a mixed-methods approach and conducted a survey with dental hygienists and semistructured interviews with dental providers. We produced frequencies and descriptive statistics for all variables and used regression modeling to explore factors related to willingness to promote the HPV vaccine. We used a deductive approach to code interview transcripts. RESULTS: Regression models using survey data (n = 470) showed that after controlling for demographic and practice-level characteristics, higher levels of willingness were associated with thinking that parents would act on a recommendation and thinking that engaging in HPV promotion is within the scope of practice. Interview data reflected willingness of dental providers to work on HPV vaccination, but revealed barriers (eg, time, knowledge) that need to be addressed. DISCUSSION: Overall, dental providers expressed a willingness to participate in HPV vaccine promotion, and future efforts should focus on addressing barriers to doing so. Engaging dental providers in HPV vaccine recommendation and referral can help prevent future HPV-related cancers.

Predictors of Multiple Jobholding among Dental Hygienists in the State of Iowa.

Purpose: Little is known about the prevalence of multiple jobholding practices among dental hygienists or the factors contributing to these employment patterns. The purpose of this exploratory study was to examine predictors of multiple jobholding practices among dental hygienists in the state of Iowa.Methods: A mailed paper survey was sent to all licensed dental hygienists (n=2080) in Iowa in May 2018. The dependent variable was whether hygienists worked more than one job in dental hygiene. Key independent variables included individual, family, and practice-related factors. Descriptive, bivariate, and binary logistic regression analyses were completed.Results: A total of 1215 dental hygienists participated in the survey, for a response rate of 58%. Among respondents, 12.2% worked more than one job overall, with 10.7% working 2 jobs and 1.5% working three or more. Respondents who had at least a bachelor's degree, did not have children in the household, were not married, had worked more years at their primary job, and worked more hours per week, were more likely to hold multiple jobs after adjusting for other factors.Conclusions: Consistent with national estimates, there was a high multiple jobholding rate among dental hygienists in Iowa. Multiple individual, family, and practice characteristics were found to be related to multiple jobholding, with the strongest predictors being the hygienist's highest level of education and the number of hours worked at the primary job.

Factors attracting Pediatric Dentists to Associateship Agreements.

Purpose: To evaluate the satisfaction of pediatric dentists in associateship agreements. Associateship agreements were deemed satisfactory if a dentist would recommend the employment experience to a colleague.
Methods: A web-based survey was administered to 6,587 pediatric dentists and pediatric dental residents in the United States in 2018. Attributes of associateships that affected dentists' decisions to join or leave a practice were examined with descriptive statistics. Logistic regression was used to identify significant associations between demographic characteristics and satisfaction with previous associateship agreements.
Results: The survey had an adjusted response rate of 13.2 percent. A total of 405 respondents reported previous experience as an associate in a pediatric dental practice; 62.0 percent of these individuals recommended their previous associateship to a colleague. Males were significantly more likely to recommend their previous associateship than females (odds ratio=1.85, 95 percent confidence interval=1.16 to 2.95). Income was the most frequently selected attribute that attracted dentists to an associateship (51.1 percent); 34.6 percent identified practice treatment philosophy as a primary reason for leaving an associateship agreement.
Conclusion: Nearly two-thirds of pediatric dentists who worked as an associate would recommend the experience to a colleague. Many dentists viewed these as positive career opportunities, even if the associateship did not culminate in buy-in or buy-out.

Prescribing practices for antibiotic prophylaxis in patients with prosthetic joints.

AIMS: With the increasing number of patients with prosthetic joints, recommendations for antibiotic prophylaxis (AP) prior to dental procedures to prevent prosthetic joint infections (PJI) have changed. METHODS AND RESULTS: This survey evaluated dentists' AP practices for patients with prosthetic joints undergoing dental procedures and their familiarity with the American Dental Association Guidelines (ADA CPG) and American Academy of Orthopaedic Surgeons Appropriate Use Criteria (AAOS AUC). Dentists' attitudes about antibiotic resistance, medical-legal aspects, and adverse effects to using AP were examined. Dentists (n = 574) were familiar (51.2%) with ADA CPG and with the AAOS AUC (25.8%). Familiarity varied according to years since graduation. Female dentists (63.5%) were more likely to be very familiar with the ADA CPG than male dentists (49.5%). Overall, 65.4% of respondents believed that AP is not effective in the prevention of PJI, and 19.4% believed there is enough evidence to support AP. For a healthy patient, 28.9% of dentists would never recommend AP, 44.9% would recommend AP within the first two years since prosthetic joint replacement. CONCLUSIONS: Dentists' recommendations for the use of AP varied depending on different factors, including health status of the patient, dental procedure, time elapsed since joint surgery, suggesting that adherence to the ADA CPG and AUC is still challenging.

Who provides open-ended comments? Assessing item nonresponse bias in Medicaid surveys of members and dentists.

OBJECTIVES: This aim of this study was to examine factors associated with survey item nonresponse to open-ended items in mailed surveys. METHODS: Data sources include two surveys conducted in Iowa in 2016 - one to a random sample of Medicaid dental program members and one to private practice dentists. Item nonresponse bias for open-ended comments was examined by comparing differences between commenters and noncommenters. Bivariate and logistic regression analyses examined differences based on demographic characteristics, attitudes, and experiences with the program, and survey mode. RESULTS: Among members, respondents who were Black, older, unemployed, had a recent dental visit, rated the plan poorly, and completed the survey on paper were significantly more likely to provide comment. Among dentists, those who participated in the plan and those who completed the survey online were significantly more likely to provide comment. CONCLUSIONS: Members and dentists with direct experiences with the Medicaid dental program were more likely to provide open-ended survey comments, whereas we found inconsistent results between members and dentists with regard to the impact of demographic characteristics, survey mode, and attitude toward the plan.

Member and dentist narratives about a dental programme for the Medicaid expansion population: A content analysis.

OBJECTIVES: In the United States, the 2010 Affordable Care Act's Medicaid expansion improved financial access to dental care for new Medicaid enrollees in states with Medicaid dental benefits for adults. Using an existing theoretical framework, we explored dentist and Medicaid member narratives concerning a state's redesigned dental programme for the Medicaid expansion population. METHODS: Data sources include two surveys conducted in 2016-one to a random sample of Medicaid members and one to private practice dentists in Iowa. A qualitative content analysis approach was used to quantify and describe themes present in open-ended comment data. RESULTS: The most common themes among Medicaid member narratives were related to oral health needs and status, availability of dentists who accept Medicaid, and Medicaid coverage for dental care. Among dentists, the programme's administrative burden was the most common theme, with coverage and reimbursement commonly cited as well. An emergent theme among both member and dentist comments was patient confusion or lack of knowledge about programme enrolment and coverage. CONCLUSIONS: Member awareness about enrolment and coverage in public dental benefit plans should be further explored to determine the impact on access to care. Effectively communicating the intent, programme design and expectations of a Medicaid programme to both providers and Medicaid members is important to the success of the programme.

A tale of two public dental benefit programs: Iowa dentist participation in traditional Medicaid versus a Medicaid expansion program.

BACKGROUND: In Iowa from 2014 to 2017, there were 2 separate public dental benefit programs for Medicaid-enrolled adults: one for the Medicaid expansion population called the Dental Wellness Plan (DWP), and one for the traditional, non-expansion adult Medicaid population. The programs differed with respect to reimbursement, administration, and benefit structure. This study explored differences in patterns and predictors of dentist participation in the two programs. METHODS: Authors sent a survey to all private practice dentists in Iowa (n = 1301) 2 years after DWP implementation. Descriptive, bivariate, and logistic regression analyses were used to examine patterns and predictors of dentist participation in Medicaid and DWP. RESULTS: Overall rates of dentists' acceptance of new Medicaid and DWP patients were 45 and 43%, respectively. However, Medicaid participants were much more likely than DWP participants to place limits on patient acceptance. Adjusting for other factors, practice busyness was the only significant predictor of DWP participation, and practice location was the only significant predictor of Medicaid participation. Dentists who were not busy enough were more than twice as likely to participate in DWP compared to others, and dentists in rural areas were almost twice as likely to participate in Medicaid compared to dentists in urban areas. CONCLUSIONS: Dentist participation in Medicaid is an ongoing concern for states aiming to ensure access to dental care for low-income populations. We found distinct participation patterns and predictors between a traditional Medicaid dental program and the DWP, suggesting different motivations for participation between the two programs.

Periodontal treatment needs in the Medicaid patient population: a retrospective study in a US dental school.

OBJECTIVES: The aim of this study was to use electronic health records (EHRs) from a US dental school clinic to retrospectively investigate associations between periodontal treatment needs and insurance type in a newly insured adult Medicaid population. We hypothesized that newly insured Medicaid patients, covered by the Iowa Dental Wellness Plan (DWP), would display greater need for treatment than patients with other sources of financing. METHODS: A retrospective chart review of EHRs of patients at the University of Iowa College of Dentistry and Dental Clinics (UI COD) from 2014 to 2016 was completed. The outcome of interest whether or not a new patient was indicated for scaling and root planing (SRP) based on clinical examination. Logistic regression models analyzed associations between treatment need and source of financing, adjusting for known periodontal disease risk indicators. RESULTS: A total of 1,259 patient charts were evaluated. SRP was indicated for 56 percent of all patients. Patients with DWP coverage had significantly greater unadjusted odds of being indicated for SRP than privately insured individuals (OR = 1.47, P = 0.009). However, this association did not remain significant after adjusting for known risk indicators. CONCLUSIONS: Although individuals enrolled in DWP were not significantly more likely to need treatment than individuals with other sources of financing when adjusting for risk indicators, their demonstrated clinical need was higher than privately insured adults. Public benefit programs could anticipate greater burden of periodontal need in low-income populations due to increased prevalence of risk factors in this population.

The patient-centered dental home: A standardized definition for quality assessment, improvement, and integration.

OBJECTIVE: To develop the first standardized definition of the patient-centered dental home (PCDH). DATA SOURCES/STUDY SETTING: Primary data from a 55-member national expert panel and public comments. STUDY DESIGN: We used a modified Delphi process with three rounds of surveys to collect panelists' ratings of PCDH characteristics and open-ended comments. The process was supplemented with a 1-month public comment period. DATA COLLECTION/EXTRACTION METHODS: We calculated median ratings, analyzed consensus using the interpercentile range adjusted for symmetry, and qualitatively evaluated comments. PRINCIPAL FINDINGS: Forty-nine experts (89%) completed three rounds and identified eight essential PCDH characteristics, resulting in the following definition: "The patient-centered dental home is a model of care that is accessible, comprehensive, continuous, coordinated, patient- and family-centered, and focused on quality and safety as an integrated part of a health home for people throughout the life span." CONCLUSIONS: This PCDH definition provides the foundation for developing measures for research, care improvement, and accreditation and is aligned with the patient-centered medical home. Consensus among a broad national expert panel-including provider, payer, and accreditation stakeholder organizations and experts in medicine, dentistry, and quality measurement-supports the definition's usability and its potential to facilitate medical-dental primary care integration.

Dental Public Health Practice, Infrastructure, and Workforce in the United States.

Dental public health is a unique specialty of dentistry that focuses on prevention of oral diseases among populations rather than individual patients. It encompasses several complementary disciplines and greatly varies in its functions and activities. Several federal, state, local, and nonpublic entities operationalize the mission of dental public health to improve population oral health through a diverse and vibrant workforce.
