Cost-effectiveness of expanding national health insurance coverage for composite resin restorations in cancer patients in South Korea.

OBJECTIVES: Cancer patients often have compromised oral health, making them vulnerable to severe dental caries and restoration failures. Due to the nature of cervical or anterior caries in cancer patients, the use of adequate restorative materials is important. However, public dental insurance coverage for composite treatments varies among countries and only glass ionomer cements (GICs) are covered in all age groups in South Korea. This study examined the cost-effectiveness of expanding national health insurance coverage to include resin composite (RC) restorations as compared with GIC in cancer patients. METHODS: Data from cancer patients who received direct restoration using GIC were identified from the National Health Screening Cohort. The relative effect of RC compared to GIC was determined through a meta-analysis, which was then utilized in calculating corresponding transition probabilities within a multi-state model. A Markov-chain Monte Carlo microsimulation was performed to estimate useful life-years and total treatment costs at the tooth level. The incremental cost-effectiveness ratio (ICER) of RC versus GIC was calculated, considering scenarios with and without expanded national health insurance coverage. The robustness of the results was confirmed through various sensitivity analyses. RESULTS: Between the two materials, RC resulted in a 0.4-year longer useful life. From a limited societal perspective, it cost $9.6 less with expanded coverage but $24.3 more without expansion, resulting in an ICER of -$25.2 and $63.9 per tooth-year, respectively. From a patient's perspective, the ICER values were -$72.7 versus $138.8 per tooth-year, respectively, translating into $200 more in savings with the expansion. Various sensitivity analyses consistently demonstrated a smaller ICER when insurance coverage was expanded. CONCLUSIONS: The expansion of national health insurance coverage to include RC restorations for cancer patients appears to be clearly cost-effective. This emphasizes the need for further policy considerations to ensure access to dental care for cancer patients. CLINICAL SIGNIFICANCE: Timely management of dental caries is crucial for cancer patients, as untreated caries can escalate into severe oral conditions, negatively impacting treatment outcomes and increasing care costs. Expanding a national health insurance coverage for cancer patients in the treatment of early dental lesions is necessary to prevent advanced dental diseases.

Enhancing seniors' dental care access: Analyzing the impact of government insurance in Canada.

A crucial policy question for the government is whether publicly funded insurance programs effectively improve access to care. Using 2015 and 2018 Canadian Community Health Survey (CCHS) data, we first estimated the effect of government dental insurance for seniors on promoting regular care access and lowering cost barrier. When controlling for individual heterogeneity, we found that having government coverage is associated with significantly lower probability of reporting avoidance of dental care due to cost compared to having no coverage. This effect is comparable with other types of insurance. However, the impact of the government program on regular access to dental care is modest. Secondly, using a portion of data collected in Alberta, we found that the government plan does not increase the overall coverage rate. Moreover, switching from an employer-based plan to government-provided coverage for seniors reduces the probability of regular access to care and increases the probability of experiencing cost barrier. This finding indicates that without expansion of overall coverage rate, the current government dental program may not be generous enough to offset the negative impact of leaving the employer-based plan.

Is private insurance enough to address barriers to accessing dental care? Findings from a Canadian population-based study.

BACKGROUND: In Canada, as in many other countries, private dental insurance addresses financial barriers to a great extent thereby facilitating access to dental care. That said, insurance does not guarantee affordability, as there are issues with the quality and level of coverage of insurance plans. As such, individuals facing barriers to dental care experience poorer oral health. Therefore, it is important to examine more keenly the socio-demographic attributes of people with private insurance to particularly identify those, who despite having insurance, face challenges in accessing dental care and experience poorer oral health. METHODS: This study is a secondary data analysis of the most recent available cycle (2017-18) of the Canadian Community Health Survey (CCHS), a national cross-sectional survey. Univariate analysis was conducted to determine the characteristics of Ontarians with private insurance (n = 17,678 representing 6919,814 Ontarians)-bivariate analysis to explore their financial barriers to dental care, and how they perceive their oral health. Additionally, logistic regressions were conducted to identify relationships between covariates and outcome variables. RESULTS: Analysis shows that the majority of those with private insurance do not experience cost barriers to dental care and perceive their oral health as good to excellent. However, specific populations, including those aged 20-39 years, and those earning less than $40,000, despite having private dental insurance, face significantly more cost barriers to access to care compared to their counterparts. Additionally, those with the lowest income (earning less than $20,000 annually) perceived their oral health as "fair to poor" more than those earning more. Adjusted estimates revealed that respondents aged 20-39 were six times more likely to report cost barriers to dental care and ten times more likely to visit the dentist only for emergencies than those aged 12-19. Additionally, those aged 40-59 were two times more likely to report poorer oral health status compared to those aged 12-19. CONCLUSION: Given the upcoming implementation of the Canadian Dental Care Plan, the results of this study can support in identifying vulnerable populations who currently are ineligible for the Plan but can be benefitted from the coverage.

Pricing in commercial dental insurance and provider markets.

OBJECTIVE: To examine the impact of commercial dental insurer and provider concentration on dentist reimbursement. DATA SOURCES: We utilized provider data from the American Dental Association, reimbursement data from IBM Watson MarketScan® Commercial Research Databases, submitted billed charges from FAIR Health® , dental insurance market concentration data from FAIR Health® , and county-level demographic and economic data from the Area Health Resources File and the Council for Community and Economic Research. STUDY DESIGN: We used the Herfindahl-Hirschman Index to separately measure commercial dental insurance concentration and dentist concentration. We studied the effect of provider and insurance concentration on dentist reimbursement. Using two-stage least squares, we accounted for potential endogeneity in dental insurer and provider concentration. PRINCIPAL FINDINGS: Across the dental procedures we examined, a 10 percent increase in dental insurance concentration is associated with a 1.95 percent (P-value = .033) reduction in gross payments to dentists. Conversely, a 10 percent increase in dentist concentration is associated with a more modest 0.71 percent (P-value = .024) increase in gross payments. A 10 percent increase in dental insurance concentration is associated with a 1.16 percentage point (P-value = .016) decline in the allowed-to-list price ratio, while a 10 percent increase in dentist concentration is associated with a 0.56 percentage point (P-value = .001) increase in the allowed-to-list price ratio. Similar patterns were found across dental procedure subcategories. CONCLUSIONS: Dental provider markets are substantially less concentrated than insurance markets, which may limit the ability of dentists to garner higher reimbursement.

Impact of Making Dental Care Affordable on Quality of Life in Adults Aged 45 Years and Older.

Objective: The objective of this study was to examine the associations between self-reported ability to afford dental care and quality of life in adults aged 45 years and older. Method: We used publicly available cross-sectional data from the 2008 National Health Interview Survey and its oral health supplement for 11,760 adults aged 45+ years. The increased probabilities of reporting dental problems attributable to an inability to afford dental care were estimated from multivariate models and combined with respective dental problem disability weights from the Global Burden of Disease to measure loss in quality of life. Results: Prevalence of reported inability to afford dental care, severe tooth loss, severe periodontitis, and untreated caries were 11.9%, 8.5%, 14.3%, and 37.9%, respectively. Inability to afford dental care was associated with an increase of 0.017 disability-adjusted life-years (DALYs) per person per year under base case and 0.020 DALYs under generous assumptions. Conclusion: Making dental care affordable could improve adult's (age 45 and above) quality of life at a reasonable cost.

The demand for preventive and restorative dental services among older adults.

Many older Americans have poor access to dental care, resulting in a high prevalence of oral health problems. Because traditional Medicare does not include dental care benefits, only older Americans who are employed, have post-retirement dental benefits or spousal coverage, or enroll in certain Medicare Advantage plans are able to obtain dental care coverage. We seek to determine the extent to which poor access to dental insurance and high out-of-pocket costs affect dental service use by the elderly. Using the 2007-2015 Medical Expenditure Panel Survey and supplemental data on dental care prices, we estimate a demand system for preventive dental services and basic and major restorative services. Selection into dental and medical insurance is addressed using a correlated random effects panel data specification. Consistent with prior studies of the nonelderly population, dental service use was not sensitive to out-of-pocket prices. However, private dental insurance increased preventive service use by 25%, and dental coverage through Medicaid increased basic and major service use by 23% and 36%, respectively. The use of services was more responsive to dental insurance for women than men. These estimates suggest that a Medicare dental benefit could significantly increase dental service use by older Americans.

What should we expect from Switzerland's compulsory dental insurance reform?

BACKGROUND: A vast and heated debate is arising in Switzerland as a result of some recent citizens' initiatives aimed at introducing compulsory dental health care insurance. The Grand Conseils of the Vaud, Geneva, and Neuchâtel cantons recently approved three public initiatives and their citizens are expected to vote on the proposal in 2018. The process of collecting signatures has begun in several other cantons and the discussion has now moved to a national level. DISCUSSION: At present, there is no scientific research that can help policy-makers and citizens to understand the main economic implications of such reform. We attempt to fill this gap by analysing three critical issues: the level and determinants of unmet needs for dental care in Switzerland; the protection of vulnerable individuals; and the economic sustainability of reform. RESULTS AND SHORT CONCLUSIONS: The results show that income is not a unique determinant of barriers to access to dental care but rather, cultural and socio-demographic factors impact the perceived level of unmet dental care needs. The reform might only partially, if at all, improve the equity of the current system. In addition, the results show that the 1% wage-based contribution that the reform promoters suggest should finance the insurance is inadequate to provide full and free dental care to Swiss residents, but is merely sufficient to guarantee basic preventive care, whereas this could be provided by dental hygienists for less.

Private dental insurance expenditure in Brazil.

OBJECTIVE To quantify the household expenditure per capita and to estimate the percentage of Brazilian households that have spent with dental insurance. METHODS We analyzed data from 55,970 households that participated in the research Pesquisa de Orçamentos Familiares in 2008-2009. We have analyzed the annual household expenditure per capita with dental insurance (business and private) according to the Brazilian states and the socioeconomic and demographic characteristics of the households (sex, age, race, and educational level of the head of the household, family income, and presence of an older adult in the household). RESULTS Only 2.5% of Brazilian households have reported spending on dental insurance. The amount spent per capita amounted to R$5.10 on average, most of which consisted of private dental insurance (R$4.70). Among the characteristics of the household, higher educational level and income were associated with higher spending. São Paulo was the state with the highest household expenditure per capita (R$10.90) and with the highest prevalence of households with expenditures (4.6%), while Amazonas and Tocantins had the lowest values, in which both spent less than R$1.00 and had a prevalence of less than 0.1% of households, respectively. CONCLUSIONS Only a small portion of the Brazilian households has dental insurance expenditure. The market for supplementary dentistry in oral health care covers a restricted portion of the Brazilian population.

How Medicare Could Provide Dental, Vision, and Hearing Care for Beneficiaries.

Issue: The Medicare program specifically excludes coverage of dental, vision, and hearing services. As a result, many beneficiaries do not receive necessary care. Those that do are subject to high out-of-pocket costs. Goal: Examine gaps in access to dental, vision, and hearing services for Medicare beneficiaries and design a voluntary dental, vision, and hearing benefit plan with cost estimates. Methods: Uses the Medicare Current Beneficiary Survey, Cost and Use File, 2012, with population and costs projected to 2016 values. Findings and Conclusions: Among Medicare beneficiaries, 75 percent of people who needed a hearing aid did not have one; 70 percent of people who had trouble eating because of their teeth did not go to the dentist in the past year; and 43 percent of people who had trouble seeing did not have an eye exam in the past year. Lack of access was particularly acute for poor beneficiaries. Because few people have supplemental insurance covering these additional services, among people who received care, three-fourths of their costs of dental and hearing services and 60 percent of their costs of vision services were paid out of pocket. We propose a basic benefit package for dental, vision, and hearing services offered as a premium-financed voluntary insurance option under Medicare. Assuming the benefit package could be offered for $25 per month, we estimate the total coverage costs would be $1.924 billion per year, paid for by premiums. Subsidies to reach low-income beneficiaries would follow the same design as the Part D subsidy.

Dental insurance, service use and health outcomes in Australia: a systematic review.

Private health insurance plays a key role in financing dental care in Australia. Having private dental insurance has been associated with higher levels of access to dental care, visiting for a check-up and receiving a favourable pattern of services. Associations with better oral health have also been reported. In the absence of any existing review, this paper aims to systematically review the relationship between dental insurance and dental service use and/or oral health outcomes in Australia. A systematic search of online databases and subsequent sifting resulted in 36 publications, 33 of which were cross sectional and three cohort analyses. Dental service outcomes were more commonly reported than oral health outcomes. There was considerable heterogeneity in the outcome measures reported, for both service use and health outcomes. Overall, the majority of the evidence was from cross sectional studies and few studies reported analyses adjusted for confounding factors. The consolidated evidence points towards a positive association between dental insurance and dental visiting. Dentally insured adults are likely to have more regular access to dental care and have a more favourable pattern of service use than the uninsured. However, evidence of associations between dental insurance and oral health are mixed.

RESUMO OBJETIVO Quantificar as despesas domiciliares per capita e estimar o percentual de domicílios brasileiros que gastaram com planos exclusivamente odontológicos. MÉTODOS Foram analisados dados de 55.970 domicílios que participaram da Pesquisa de Orçamentos Familiares em 2008-2009. Os gastos domiciliares anuais per capita com planos exclusivamente odontológicos (empresarial e particular) foram analisados segundo os estados da federação e as características socioeconômicas e demográficas dos domicílios (sexo, idade, cor da pele e escolaridade do chefe do domicílio, renda familiar e presença de idoso no domicílio). RESULTADOS Apenas 2,5% dos domicílios brasileiros relataram gastos com planos exclusivamente odontológicos. O valor per capita despendido somou em média R$5,10, sendo a maior parte composta por planos odontológicos particulares (R$4,70). Entre as caraterísticas do domicílio, maior escolaridade e renda estiveram associadas com maior gasto. São Paulo foi o estado com maior gasto domiciliar per capita (R$10,90) e maior prevalência de domicílios com dispêndios (4,6%), enquanto Amazonas e Tocantins apresentaram os menores valores, ambos com gasto inferior a R$1,00 e com menos de 0,1% de domicílios, respectivamente. CONCLUSÕES Apenas uma pequena parcela dos domicílios brasileiros desembolsa com planos exclusivamente odontológicos. O mercado de odontologia suplementar na assistência em saúde bucal abrange uma restrita parcela da população brasileira.

Designing a New Payment Model for Oral Care in Seniors.

With 10,000 baby boomers turning 65 every day, many will be on fixed incomes and will lose dental insurance upon retirement. This article presents why a dental benefit in Medicare might save the US government money, and who would likely benefit. It details an approach to estimating costs of inclusion of a dental benefit in Medicare, and compares the proposed approach to existing proposals. Additionally, the ensuing steps needed to advance the conversation to include oral health in healthcare for the aged will be discussed.

Getting the Incentives Right: Improving Oral Health Equity With Universal School-Based Caries Prevention.

Despite significant financial, training, and program investments, US children's caries experience and inequities continued to increase over the last 20 years. We posit that (1) dental insurance payment systems are not aligned with the current best evidence, exacerbating inequities, and (2) system redesign could meet health care's triple aim and reduce children's caries by 80%. On the basis of 2013 to 2016 Medicaid and private payment rates and the caries prevention literature, we find that effective preventive interventions are either (1) consistently compensated less than ineffective interventions or (2) not compensated at all. This economic and clinical misalignment may account for underuse of effective caries prevention and subsequent overuse of restorative care. We propose universal school-based comprehensive caries prevention to address this misalignment. Preliminary modeling suggests that universal caries prevention could eliminate 80% of children's caries and cost less than one fifth of current Medicaid children's oral health spending. If implemented with bundled payments based on cycle of care and measurable outcomes, there would be an alignment of incentives, best evidence, care, and outcomes. Such a program would meet the Healthy People Oral Health goals for children, as well as health care's triple aim.
