Imani K, Hill CM, Chi DL. Emergency department use for nontraumatic dental conditions for children with special health care needs enrolled in Oregon Medicaid. J Am Dent Assoc 2024; 155:1031-1042. [PMID: 39503646 DOI: 10.1016/j.adaj.2024.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2024] [Revised: 08/13/2024] [Accepted: 09/09/2024] [Indexed: 11/08/2024]
Abstract
BACKGROUND This cross-sectional study evaluated whether children with special health care needs (CSHCN) were more likely to use the emergency department (ED) for nontraumatic dental conditions (NTDCs) than children without special health care needs (SHCN). The study also examined whether the likelihood of receiving an opioid prescription after an NTDC-ED visit differed between children with and without SHCN. METHODS This analysis was based on 2017 Oregon Medicaid enrollment, claims, and pharmacy data (N = 225,614 children aged 3-17 years). To assess associations between SHCN, NTDC-ED use, and receipt of opioid prescriptions, confounding variable-adjusted odds ratios and 95% CIs were generated from logistic regression models. RESULTS Approximately 14% (n = 31,867) of children had an SHCN. The prevalence of NTDC-ED use was 0.36% (n = 807) for all children. In the confounding variable-adjusted model, the odds of NTDC-ED use were 1.6 times greater for CSHCN than children without SHCN (95% CI, 1.3 to 1.9; P < .001). Among children with an NTDC-ED visit, 8.3% received an opioid prescription. In the confounding variable-adjusted model, CSHCN were at lower odds of receiving an opioid prescription after an NTDC-ED visit than children without SHCN, but this difference was not statistically significant (odds ratio, 0.84; 95% CI, 0.4 to 1.6; P = .57). CONCLUSIONS CSHCN enrolled in Medicaid had significantly higher odds of having NTDC-ED visits than children without SHCN, but there was no significant difference between the 2 groups in the odds of receiving an opioid prescription after an NTDC-ED visit. PRACTICAL IMPLICATIONS All children, especially those with SHCN, should have adequate access to office-based oral health care through a dental home to reduce use of the ED for NTDC.

How Phantom Networks, Provider Qualities, and Poverty Sway Medicaid Dental Care Access: A Geospatial Analysis of Manhattan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182312383. [PMID: 34886108 PMCID: PMC8656799 DOI: 10.3390/ijerph182312383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 11/03/2021] [Accepted: 11/12/2021] [Indexed: 11/17/2022]
Abstract
Access to general dental care is essential for preventing and treating oral diseases. To ensure adequate spatial accessibility for the most vulnerable populations, New York State mandates a ratio of one general dentist to 2000 Medicaid recipients within 30 min of public transportation. This study employed geospatial methods to determine whether the requirement is met in Manhattan by verifying the online directories of ten New York managed care organizations (MCOs), which collectively presented 868 available dentists from 259 facilities. Our survey of 118 dental facilities representing 509 dentists revealed that significantly fewer dentists are available to treat Medicaid recipients compared to MCO directories. The average dentist-to-patient ratio derived from the MCO listings by the Two-Step Floating Catchment Area (2SFCA) method was 1:315, while the average verified ratio was only 1:1927. “Phantom networks”, or inaccurate provider listings, substantially overstated Medicaid dental accessibility. Surprisingly, our study also discovered additional Medicaid providers unlisted in any MCO directory, which we coined “hidden networks”. However, their inclusion was inconsequential to the overall dental supply. We further scrutinized dental care access by uniquely applying six “patient-centered characteristics”, and these criteria vastly reduced accessibility to an average ratio of merely 1:4587. Our novel evaluation of the spatial association between poverty, dental care access, and phantom networks suggests that Medicaid dental providers wish to be located in wealthier census tracts that are in proximity to impoverished areas for maximum profitability. Additionally, we discovered that poverty and phantom networks were positively correlated, and phantom providers masked a lack of dental care access for Medicaid recipients.

Abstract
OBJECTIVES To examine differences between Hispanics and non-Hispanics in Florida in the dental-related use of hospital emergency departments (EDs). METHODS We used ambulatory ED discharge records from 2013 to 2015 to compute rates of ED visits for dental complaints per 10 000 population, by region, age, gender, and the percentage distribution visits by primary payer, day of the week, and hour of arrival. RESULTS There were 64 100 ED visits for dental complaints by Hispanics and 425 162 by non-Hispanics. Medicaid was the most common primary payer for Hispanics (42.2%) and for non-Hispanics (38.1%). Rates of ED utilization for dental problems per 10 000 population were 45.5 for Hispanics and 95.2 for non-Hispanics. CONCLUSIONS Rates of ED utilization for dental problems were different between Hispanics and non-Hispanics. Public Health Implications. Effective interventions need to be developed in the context of a social-ecological model to better understand factors such as health, economics, and education, among others. Understanding and intervening with the individual, communities, and policy could help to modify behaviors and improve access to dental care.

Abstract
OBJECTIVE This study validated two Dental Quality Alliance system-level measures of oral healthcare quality for children - caries-related emergency department (ED) visits and timely follow-up of those visits with a dentist - including formal validation of diagnosis codes used to identify caries-related ED visits and measurement of follow-up care. METHODS The measures were specified for implementation with administrative claims data and validated using data from the Florida and Texas Medicaid and Children's Health Insurance Programs. Measure specification testing and measure score validation used administrative data for 7,007,765 children. We validated the diagnosis codes in claims data by comparisons with manual reviews of 300 records from a Florida hospital ED and calculation of the kappa statistic, sensitivity, and specificity. RESULTS Overall agreement in caries-related ED visit classifications between the claims data and record reviews was 87.7 percent with kappa = 0.71, sensitivity = 82 percent, and specificity = 90 percent. The calculated measure scores using administrative data found more than four-fold variation between programs with the lowest and highest caries-related ED visit rates (6.90/100,000 member months and 30.68/100,000 member months). The percentage of follow-up visits within 7 days and 30 days ranged from 22-39 percent and 34-49 percent, respectively. CONCLUSIONS These National Quality Forum endorsed measures provide valid methodologies for assessing the rate of caries-related ED visits, an important system-level outcome indicator of outpatient prevention and disease management, and the timeliness of follow-up with a dentist. There is significant variation in caries-related ED visits among state Medicaid programs, and most ED visits do not have follow-up with a dentist within 30 days.

Abstract
Background Emergency department (ED) visits for dental reasons continue to impact EDs nationwide. This investigation determined the rate of follow-up in an emergency dental clinic (EDC) after hospital ED visits for nontraumatic dental conditions. Methods This prospective investigation reports the number of patients who presented to an ED for nontraumatic dental conditions and the rate of follow-up at an EDC. Upon ED discharge, patients were provided instructions to follow-up for low-cost care at the EDC. Telephone contact was attempted following failed referrals. Descriptive statistics were reported for comparing referral sources and demographic trends. Results Two hundred and forty-seven referrals were made and 31% followed up for definitive treatment at the EDC. More referrals were made on weekends than on weekdays. Failed referrals were unreachable by telephone in 75% of cases. Tooth extraction was the most common treatment rendered in the EDC. Of the ED patients who accessed EDC care, 14% became comprehensive patients in the EDC’s regular dental clinic. Conclusion Less than one-third of ED referrals to the EDC followed up for definitive care when provided an opportunity to do so, and 75% of referrals were unreachable by telephone in the week following the ED dental visit.

Abstract
OBJECTIVES Prior studies document increased numbers of nontraumatic dental condition (NTDC) visits to U.S. emergency departments (EDs). However, the influence of travel distance on ED use for NTDCs, particularly for Medicaid enrollees has hitherto received little attention. The authors examined the effect of travel distance on Wisconsin Medicaid enrollees' NTDC visits to EDs after adjustment for covariates. METHODS NTDC-related visits claims data for Wisconsin Medicaid (2001-2009) was analyzed. For each enrollee, travel distance to the nearest of 130 EDs in Wisconsin was determined. The number of NTDC visits per person-year was aggregated by ZIP+4 of residence. Negative binomial regression adjusting for the expected number of visits based on race, sex, age of the residents and calendar year was used to evaluate the effect of travel distance, urbanicity, and dentist-population ratio on rate of visits. RESULTS Enrollees residing in rural counties, entire dental health professional shortage areas, areas with dentist population ratios >20,000: 1 and non-Hispanic Whites travelled the furthest, compared to nearest mean ED distance of 2.9 miles. Enrollees residing 3 miles away or further had significantly lower rates of NTDC visits to EDs. CONCLUSIONS This study demonstrates that distance is a barrier to making NTDC-related visits to EDs. Rates of NTDC visits decreased as travel distance to the nearest ED increased for Medicaid enrollees.

Abstract
BACKGROUND Periapical periodontitis, also known as periapical lesion, is a common dental disease, along with periodontitis (gum disease). Periapical periodontitis is a chronic inflammatory disease, caused by endodontic infection, and its development is regulated by the host immune/inflammatory response. Metabolic disorders, which are largely dependent on life style such as eating habits, have been interpreted as a "metabolically-triggered" low-grade systemic inflammation and may interact with periapical periodontitis by triggering immune modulation. The host immune system is therefore considered the common fundamental mechanism of both disease conditions. METHOD We have reviewed >200 articles to discuss the interrelationship between periapical lesions and metabolic disorders including type 2 diabetes mellitus, hypertension, and non-alcoholic fatty liver diseases (NAFLD), and their common pathological background in immunology/osteoimmunology and cytokine biology. RESULTS An elevated inflammatory state caused by metabolic disorders can impact the clinical outcome of periapical lesions and interfere with wound healing after endodontic treatment. Although additional well-designed clinical studies are needed, periapical lesions appear to affect insulin sensitivity and exacerbate non-alcoholic steatohepatitis. CONCLUSION Immune regulatory cytokines produced by various cell types, including immune cells and adipose tissue, play an important role in this interrelationship.

Abstract
INTRODUCTION Facial computed tomography (CT) is often performed in the emergency department as a part of the diagnostic workup for patients presenting with the signs and symptoms of dentoalveolar abscess (DA). This investigation evaluated the diagnostic yield of the facial CT and its effects on management change in patients suspected of DA. Furthermore, we assessed secondary consequences of routine facial CT use in this population by using turn-around time (TAT), cost, and radiation exposure as the key parameters. MATERIAL AND METHODS We retrospectively reviewed records of suspected DA patients over a 5-year period, from June 2008 to June 2013. TAT was calculated for patients from the time the examination was ordered by the emergency department physician, to the time the report was finalized by the attending radiologist. Effective radiation dose for facial CT was calculated by multiplying dose length product by the standard conversion coefficient K (K = 0.0021 mSv/mGy x cm). CT cost was included for reference but was not analyzed extensively due to the lack of standardization of costs across the various institutions. RESULTS Our investigation consisted of 117 patients; 75 males of average age 41 (±12) years and 42 females of average age 44 (±17) years. Out of the total 117 patients that underwent CT for the suspicion of a simple DA, only a single individual (0.85%) underwent a management change. Mean TAT of facial CT was 110 (±63) minutes, and a median TAT was 87 (±71) minutes. Average effective radiation dose for a facial CT was 2.4 (±0.4) mSv. Approximate estimated cost of a contrast enhanced facial CT was $253 and non-contrast facial CT was $209. CONCLUSION Our study shows that routine use of facial CT has a very limited diagnostic value in the workup of simple DA and rarely results in management change. The overall impact on patient management is miniscule in the context of prolonged TAT, radiation exposure, and adding to the rising medical costs.

Abstract
PURPOSE Prescription drug overdose (PDO) deaths are a critical public health problem in the United States. This study aims to assess the association between emergency department (ED) utilization patterns in a cohort of ED patients and the risk of subsequent unintentional PDO mortality. METHODS Using data from the New York Statewide Planning and Research Cooperative System for 2006-2010, a nested case-control design was used to examine the relationship between ED utilization patterns in New York State residents of age 18-64 years and subsequent PDO death. RESULTS The study sample consisted of 2732 case patients who died of PDO and 2732 control ED patients who were selected through incidence density sampling. With adjustment for demographic characteristics, and diagnoses of pain, substance abuse, and psychiatric disorders, the estimated odds ratios of PDO death relative to one ED visit or less in the previous year were 4.90 (95% confidence interval [CI]: 4.50-5.34) for those with two ED visits, 16.61 (95% CI: 14.72-18.75) for those with three ED visits, and 48.24 (95% CI: 43.23-53.83) for those with four ED visits or more. CONCLUSIONS Frequency of ED visits is strongly associated with the risk of subsequent PDO death. Intervention programs targeting frequent ED users are warranted to reduce PDO mortality.
