Perinatal Oral Health Among Underserved Women: A Call to Action for North Carolina Patients, Providers and Policymakers

Race, Ethnicity, and Other Barriers to Access Dental Care During Pregnancy

BACKGROUND

Historically, women of color showed poorer oral health and lower dental service utilization in the USA. These barriers to dental care during pregnancy included dental coverage, primary language, dental provider availability, safety concerns, affordability of dental care, and perceived oral health benefits during pregnancy.

METHODS

The purpose of this study is to examine whether race/ethnicity modified the associations between barriers to accessing dental care and dental service utilization during pregnancy. This cross-sectional study sample included 62,189 women aged 20 and older with a recent birth history in 21 states from the Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2016 to 2019. We introduced a race/ethnicity by barrier interaction term to our multiple logistic regression models.

RESULTS

After adjusting for other confounders, dental insurance during pregnancy and perceived oral health benefits were associated with 4.0- and 5.6-fold higher odds, respectively, of dental service utilization during pregnancy. Statistically significant effect modification by race/ethnicity was observed in crude and adjusted analyses of the relationship between dental service utilization for all barriers included in the interaction analyses with all adjusted p-values < 0.001.

CONCLUSION

The interaction analysis found that racial/ethnic disparity in visiting dentists during pregnancy was significant among women who reported these dental barriers. In contrast, such racial/ethnic disparity was substantially attenuated among women who did not report such barriers.

PRACTICAL IMPLICATIONS

The observed racial/ethnic disparities could be mitigated by such supporting mechanisms: dental coverage, provider availability and willingness to treat pregnant women, oral health education on the safety of dental care during pregnancy, and affordable dental care costs.

Oral Health of Women and Children: Progress, Challenges, and Priorities

INTRODUCTION

Tooth decay remains the most prevalent chronic disease in children and adults, even though it is largely preventable. Studies show that mothers' oral and overall health is linked to children's oral health and pregnancy outcomes. This paper examines achievements during the last 20 years, assesses current challenges, and discusses future priorities.

ORAL HEALTH STATUS

Data show a modest improvement in children's oral health during the last 20 years; however, tooth decay still affects more than half of adolescents. According to national survey data, about 26% of working-age adults had untreated tooth decay. Overall, significant oral health disparities by race/ethnicity and income persist.

DENTAL SERVICE UTILIZATION

The annual dental visit rate for children in the 2015 Medical Expenditure Panel Survey was 48%. Among children enrolled in Medicaid, dental visit rates increased from 18% in 1993 to nearly 50% in 2018. About 46% of women are estimated to receive teeth cleaning during pregnancy. Over the years, race or ethnicity and income-level differences in dental visits observed in the early 2000s have narrowed substantially in children but not among pregnant women.

DISCUSSION

Many effective interventions are available at the community and individual levels but are underutilized. Lack of integration of oral health into the overall health care system and programs, community conditions, poverty, and limited health literacy make it difficult for families to engage in healthy habits, use preventive interventions, and access treatment promptly.

CONCLUSION

To further improve oral health, policy and system reforms are needed to address the factors mentioned above. Therefore, we urge the federal Maternal and Child Health Bureau to take steps to convene a workshop to develop a framework for future actions.

Implementing a Prenatal Oral Health Program for Dental Students: Lessons Learned

The Prenatal Oral Health Program (pOHP) was developed to educate dental students on prenatal oral health and promote access to dental care for pregnant women. Program advancement has occurred in support of quality improvement. This mixed-methods design combined quantitative data from fourth-year dental students who participated the pOHP (N = 81) and qualitative data from a student-faculty-staff focus group discussion (N = 7). Different clinical structures, appropriate leveling in the curriculum, management with a patient care coordinator, and inclusion of interprofessional learning experiences (IPE) were compared. The survey response rate was 96.4% (N = 81). Trends were noted between students who provided clinical care for a pregnant patient (31%) versus those who did not. Results indicated that an integrated clinic was preferred, though students who had treated a pOHP patient showed greater support for a standalone clinic model. Survey and focus group data agreed that pOHP should occur during the third-year dental school training; however, students with patient experience favored second-year placement. Survey and focus group data emphasize the importance of a patient care coordinator for clinical management and IPE as an essential learning element. Innovating new clinical models requires a period of evolution to determine preferred and sustainable infrastructure. Results reveal the advantages and disadvantages of various program implementation models and demonstrate that student perceptions were influenced by their clinical experiences. Study findings will inform implementation and guide other programs as they create and modify existing curricula to enhance prenatal oral health.

The who, what, where, when and why of engaging with policymakers: A critical reflection

Improving relationships between researchers and policymakers is one element of knowledge mobilisation that has proven to increase the translation of research into policy. However, researchers report they find it difficult to engage policymakers with research. In this article, a personal narrative approach was used to analyse my experience, as a PhD candidate, when engaging policymakers to participate in a qualitative research study. A total of 93 contacts were made in an attempt to recruit policymakers; these contacts consisted of both policymakers and knowledge brokers. The experience of contacting and engaging with policymakers identified barriers other researchers may experience and offers enablers to assist when engaging policymakers. This reflective approach resulted in the development of the five following themes: who you know, what ifs, when is it enough, where is the research going and why value is important. These five themes can act as a guide for researchers when preparing to engage policymakers into research.

Retrospective Study of Prenatal and Postnatal Gaps in Oral Health Care Utilization: Medicaid Policy Implications

OBJECTIVE

To assess the frequency and timing of dental treatment completion among pregnant and post-partum women served through the University of North Carolina at Chapel Hill (UNC-CH) Prenatal Oral Health Program (pOHP) dental clinic in the context of North Carolina (NC) dental Medicaid policies.

METHODS

We completed a retrospective chart review of pregnant women referred to the program between May 2015 and May 2019. Data were collected from the time of referral until up to 2 years after their estimated due date (EDD). We assessed pre- and post-delivery dental appointment timing and dental treatment completion.

RESULTS

The initial study population included 264 pregnant women. Overall, 213 patients (81%) attended at least one appointment, and 32 patients (12%) completed recommended treatments prior to their EDD. Fifty patients (19%) returned after delivery to resume dental care, with only 25 patients (10%) completing their recommended treatment plan. Women re-entered dental care at a median of 67 days (range 5-613 days) after their EDD and completed treatment at a median of 378 days (range 52-730 days) following delivery.

CONCLUSIONS FOR PRACTICE

Despite dental clinic referral, most pregnant women do not complete recommended dental treatment before giving birth, and women who resumed dental care after birth demonstrated a lag-time between delivery and care completion. These findings highlight the need for extending post-pregnancy dental care coverage, which is limited under current dental Medicaid policies, posing a major public health issue for new mothers to continue oral health care.

County-level correlates of dental service utilization for low income pregnant women. Ecologic study of the North Carolina Medicaid for Pregnant Women (MPW) program

Background

Dental care utilization for low income pregnant women is met with challenges in the traditional dentist-centered model of care. County-level measures provide insights for policy and roles for stakeholders that extend beyond the dentist-patient relationship. We examined county-level data to generate hypotheses about factors that influence utilization of dental services in North Carolina’s Medicaid for Pregnant Women (MPW) program.

Methods

County-level Medicaid utilization data for dental services for 2014–2016 were pooled to get mean county estimates of dental utilization in the MPW program. Descriptive statistics and multivariate regression models of dental utilization and county-level measures are presented. Data used were collected by NC Child and the Robert Wood Johnson Foundation’s County Health Rankings Reports. USDA Economic Research Service data were used to categorize counties in terms of Farming, Recreation, Persistent Poverty, and metro/non-metro status using Rural Urban Continuum Codes.

Results

Dental utilization ranged from 1–26% with a median of 8.5% across the 100 counties of North Carolina. Strong patterns linking utilization of dental services in the MPW program to contextual social measures of well-being emerged, specifically, increased reporting of child abuse and neglect, elevated infant mortality, poor quality of life, and worse ranking in years of potential life lost. Counties with persistent poverty had lower rates of dental utilization.

Conclusions

Utilization of dental services in the MPW program is generally low. Patterns identify the potential for enhancing community-clinical linkages to improve birth outcomes and care coordination for pregnant women to enhance dental utilization in this population.

Dental coverage in the Medicaid program in most states is administered separately from medical coverage. The separation of the funding mechanisms adds a further layer of complexity to care integration. Efforts to enhance dental care for pregnant women in the Medicaid program may benefit from policy that aligns incentives for care coordination within the community. Policy that extends the window of eligibility for dental benefits to 24 months after the birth of the child will help women complete the dental treatment that is needed. This also leverages the value of care coordination for community stakeholders from diverse child health sectors.
