Hospital-Based Emergency Department Visits With Dental Conditions: Impact of the Medicaid Reimbursement Fee for Dental Services in New York State, 2009-2013

Synthesizing 30-years of adult medicaid dental policy research: A scoping review to identify gaps and opportunities

Objective

Despite the importance of Medicaid for the oral health of low-income adults, the extent to which Medicaid dental policy variation influences outcomes is unknown. This study aims to review the evidence evaluating adult Medicaid dental policies to synthesize conclusions and motivate future research.

Data sources

A comprehensive search of academic literature published in English between 1991 and 2020 was conducted to identify studies which evaluated an adult Medicaid dental policy for its effect on outcomes. Studies strictly involving children, policies not related to adult Medicaid dental coverage, and non-evaluation studies were excluded. The data analysis identified the policies, outcomes, methods, populations, and conclusions of the included studies.

Results

Among the 2731 unique articles extracted, 53 met the inclusion criteria. 36 studies evaluated the effect of expanding Medicaid dental coverage, which was found to consistently increase dental service visits (21 studies) and reduce unmet dental needs (4 studies). Provider density, reimbursement rates, and level of benefits appear to influence the effect of expanding Medicaid dental coverage. The evidence for changing Medicaid benefits and reimbursement rates were mixed for its impact on provider participation and emergency dental services. Few studies examined how adult Medicaid dental policies impact health outcomes.

Conclusions

Most of the recent research has focused on evaluating the effect of expanding or reducing Medicaid dental coverage on dental service utilization. Future research investigating the impact of adult Medicaid dental policies on clinical, health, and wellness outcomes remains warranted.

Clinical significance

Low-income adults are responsive to Medicaid dental policy changes and utilize more care with more generous coverage. Less is known about how these policies influence health.

Spending on emergency care due to nontraumatic dental conditions in the United States, 1996 through 2016

BACKGROUND

Emergency department (ED) use for oral health care is a growing problem in the United States. The objective of the study was to describe spending on ED visits due to nontraumatic dental conditions (NTDCs) in the United States and to quantify changes in spending and its drivers.

METHODS

Spending estimates for ED visits due to NTDCs according to type of payer were analyzed for the period from 1996 through 2016 and estimates about the drivers of change were analyzed for the period from 1996 through 2013. NTDCs included caries, periodontitis, edentulism, and other oral disorders. Estimates were calculated according to age, sex, and type of payer (that is, public, private, and out of pocket), adjusted for inflation, and expressed in 2016 US dollars. The estimate of expenses was decomposed into 5 drivers for the period from 1996 through 2013 (that is, population, aging, prevalence of oral disorders, service use, and service price and intensity).

RESULTS

The total change in spending from 1996 through 2016 amounted to $540 million, an increase of 216%. The drivers of changes in spending from 1996 through 2013 were price and intensity ($360 million), service use ($220 million), and population size ($68 million).

CONCLUSIONS

Spending on ED visits due to NTDCs more than tripled during the study period, with price and intensity representing the main drivers. This increase was primarily in adults and paid via the public sector.

PRACTICAL IMPLICATIONS

Possible solutions include strengthening the oral health care safety net, especially for the most vulnerable populations.

The impact of underutilization of preventive dental care by adult Medicaid participants

Objective

To ascertain the financial impact associated with the underutilization of preventive dental care for adults enrolled in Medicaid.

Methods

We used adult claims data for patients aged 21–64 in the IBM Watson Marketscan Medicaid database. Enrollees were included if they had at least one dental claim in 2019 and were continuously enrolled between 2014 and 2019. We then evaluated the costs of their dental care in 2019, based on the number of years of preventive dental care they received between 2014 and 2018. We also assessed Emergency Department (ED) utilization for dental conditions, oral surgeries, and dental‐related opioid prescriptions.

Results

The average Medicaid enrollee with five continuous years of preventive care prior to 2019 experienced 43% lower costs than an individual who received no preventive dental care at all. Most of the savings were a result of fewer oral surgeries. A Medicaid enrollee with no preventive dental visits was eight times more likely to have an ED visit for a nontraumatic dental condition (NTDC), seven times more likely to have oral surgery and six times more likely to receive a dental‐related opioid prescription compared to those who had a dental prevention visit every year in the 5‐year lookback period.

Conclusions

Regular preventive dental care in the lookback period was associated with significant savings in overall dental care costs when compared to dental care costs for those individuals who received no or few preventive visits. Prior preventive dental care was also associated with lower rates of ED‐NTDC utilization, oral surgery, and dental‐related opioid prescriptions.

Emergency department visits for infectious oral conditions in Massachusetts, 2014 through 2018

BACKGROUND

The authors aimed to measure population-based preventable emergency department (ED) visits related to infectious oral conditions (IOCs) in Massachusetts and to examine the associated sociodemographic factors to support prevention efforts.

METHODS

A statewide retrospective analysis of ED visits related to IOCs in Massachusetts from 2014 through 2018 was conducted using a Center for Health Information and Analysis database. The authors described patients' characteristics, dental diagnoses frequencies, emergency severity, lengths of stay, associated treatment, and costs. Multilevel logistic regression was used to assess factors associated with IOC visits.

RESULTS

IOC visits in 2014 through 2018 were 1.2% (149,777) of the total ED visits, with an estimated cost of $159.7 million. There was an annual decline in the prevalence of IOC visits from 2014 through 2018. After adjusting for sociodemographic factors, odds of IOC were higher among males (adjusted odd ratio [AOR], 1.26; 95% CI, 1.24 to 1.27), non-Hispanic Blacks compared with non-Hispanic Whites (AOR, 1.03; 95% CI, 1.02 to 1.06), people residing in dental health care professional shortage areas (AOR, 1.06; 95% CI, 1.04 to 1.07), public insurance beneficiaries (AOR, 1.90; 95% CI, 1.87 to 1.93), or uninsured (AOR, 2.60; 95% CI, 2.54 to 2.66) compared with privately insured.

CONCLUSIONS

There was an annual decline in the prevalence of IOC visits from 2014 through 2018. Higher odds of IOC visits were associated with young adults, Black patients, uninsured people, public insurance beneficiaries, and people who reside in dental health care professional shortage areas.

PRACTICAL IMPLICATIONS

The authors provided statewide data to support proposed policies to improve oral health care in Massachusetts. IOCs are mostly preventable, but well-coordinated care between medicine and dentistry is integral for prevention.

A systematic review of dental-related emergency department among Medicaid beneficiaries

OBJECTIVES

Dental-related emergency department (ED) visits are a growing public health concern. Dental insurance coverage is a strong predictor of dental service access. The objective of this study was to conduct a systematic review to assess the incidence of dental-related ED visits for Medicaid dental enrollees compared to those with other insurances.

METHODS

PubMed, EMBASE, and Google Scholar were searched for surveillance and observational data published in English from January 1999 to April 2020 to address the following PECOT question: Do patients with nontraumatic dental conditions (NTDC) (P1), or patients with any dental condition (P2) who have Medicaid (E) compared to other insurance status (private insurance, Medicare, no insurance) (C) have a differential incidence of single dental-related ED visits (O) in the literature search results from 1999 to April 2020 (T)? A critical appraisal was performed using a combination of the AXIS tool (for cross-sectional studies with observational data and MetaQAT (for public health evidence).

RESULTS

This systematic review included 32 studies. Overall, risk of bias was low. Due to significant statistical heterogeneity, a synthesis without meta-analysis was conducted. NTDC ED visits ranged from 16.0 percent to 79.8 percent for Medicaid patients and 0.9 percent to 57.2 percent for uninsured patients. The range for any dental visit to the ED was 2.2-63.8 percent for Medicaid patients and 2.9-40.8 percent for uninsured patients.

CONCLUSIONS

The results of this study support expanding insurance coverage in Medicaid programs to reduce ED use for NTDC visits in the United States.
