Who's declining the "free lunch"? New evidence from the uptake of public child dental benefits

Change in Dental Visits Among Eligible Children Under the Impact of the Child Dental Benefits Schedule in Australia

OBJECTIVES

In Australia, although there have been some improvements, child oral health continues to be a major public health issue. The Australian Government introduced the means-tested Child Dental Benefits Schedule (CDBS) in 2014 to support access to dental services for children and adolescents aged 0-17 years from low-income families. There is a lack of evidence documenting whether the CDBS improved the dental attendance rate. This study aimed to evaluate the impact of the CDBS on dental visits among eligible children and adolescents in Australia.

METHODS

The study analysed the data set from the birth cohort (B cohort) in the Longitudinal Study of Australian Children (LSAC). This is a nationally representative cohort survey collected biennially since 2004. The information on dental visits in the last 12 months was reported by the parents. A difference-in-differences analysis was used to examine 22,985 observations in the period 2008-2018. A propensity score matching (PSM) method was employed as a robustness check for the main findings.

RESULTS

The proportion of children and adolescents eligible for CDBS in the six biennial surveys from 2008 to 2018 was 62.0%, 54.4%, 47%, 41.2%, 35.5%, and 28.9%, while the proportion of eligible individuals visiting dentists was 38.0%, 45.6%, 53.0%, 58.8%, 64.5%, and 71.1%, respectively. The analyses showed that the CDBS policy had a statistically significant and positive impact on dental visits among eligible children and adolescents. There was a 6.1-6.4 percentage point increase (p-value < 0.001) in dental visits across different specifications after the introduction of the CDBS policy.

CONCLUSION

The removal of financial barriers was beneficial to improve dental visits; however, the target group still faces the other remaining barriers, especially those related to inequalities in the social determinants of health, impeding the uptake of free dental services.

Use of free preventive dental programme for children: 10 years of Lov'U'r Teeth, France

AIM

Lov'U'r Teeth is a French oral health prevention programme targeting children. The programme offers an appointment with a dentist for oral examination and individual oral health advice. It covers any necessary primary dental care resulting from that examination. Despite being free, it was under-utilised at its previous evaluation 10 years ago. The study aims to identify the determinants of participation and their evolution since 2009.

METHODS

We worked on the General Beneficiary Sample, a medico-administrative database representative of the French population, including health-care consumption data. We selected individuals aged 6 to 15. We performed descriptive statistics and multivariate logistic regressions to analyse and compare the determinants of participation between 2009 and 2019. The final sample included 26 288 children.

RESULTS

Lov'U'r Teeth participation rate increased by 4.2 percentage points from 2009 to 2019. Participation was highest at age 6 and declined as age increased. Children from households facing financial difficulties have a 72% lower probability of participating than other children. Over the study period, increasing poverty rates were consistently associated with lower participation. Children living in the areas with the highest poverty rates were up to 46% less likely to participate than those in areas with the lowest poverty rates.

CONCLUSION

Participation in Lov'U'r Teeth has improved over the past 10 years, but the programme continues to reproduce social inequalities, as the determinants of using free preventive dental care mirror those of non-preventive care. Lov'U'r Teeth should enhance communication strategies to reach those in need and clarify the programme's benefits.

Socially constructed beliefs and the uptake of the Child Dental Benefits Schedule

BACKGROUND

The Child Dental Benefits Schedule (CDBS) provides automatic access to subsidized dental care for eligible Australian children, but uptake is low. As cost is not a factor, socially constructed perceptions, which may be subscribed to without personal experience, were explored as potential barriers.

METHODS

Two studies with parents (child <18 years) were conducted. In Study one (N=317) participants completed a free-response task eliciting socially constructed perceptions about the dentist. These were factor-analysed in Study two (N=231), and the salience of these perceptions in relation to uptake was measured for the 113 eligible to access the CDBS participants.

RESULTS

In Study one, similar positive, negative, procedural and time words were elicited across conditions. Study two revealed Negative, Positive and Hassle perception factors associated with the dentist and that 61% of eligible participants had accessed the CDBS. Generalized Structural Equation Modelling with eligible participants revealed Positive and Negative perceptions were negatively correlated, Negative perceptions were positively correlated with Hassle, and, as Hassle increased, the probability of parents accessing the CDBS significantly decreased.

CONCLUSIONS

Confusion around eligibility to access CDBS is still an issue. Low CDBS uptake may be associated with perceived hassle associated with the dentist, which may reflect parental negative perceptions. © 2024 Australian Dental Association.

Accuracy of self-reported private health insurance coverage

Studies on health insurance coverage often rely on measures self-reported by respondents, but the accuracy of such measures has not been thoroughly validated. This paper is the first to use linked Australian National Health Survey and administrative population tax data to explore the accuracy of self-reported private health insurance (PHI) coverage in survey data. We find that 11.86% of individuals misreport their PHI coverage status, with 11.57% of true PHI holders reporting that they are uninsured and 12.37% of true non-insured persons self-identifying as insured. Our results show reporting errors are systematically correlated with individual and household characteristics. Our evidence on the determinants of errors is supportive of common reasons for misreporting. We directly investigate biases in the determinants of PHI enrollment using survey data. We find that, as compared to administrative data, survey data depict a quantitatively different picture of PHI enrollment determinants, especially those capturing age, gender, language proficiency, labor force status, disability status, number of children in the household, or household income. We also show that PHI coverage misreporting is subsequently associated with misreporting of reasons for purchasing PHI, type of cover and length of cover.

Prioritizing population oral health through public policy in Australia: the Victorian experience

Dental caries, a non-communicable disease, is one of the most prevalent diseases globally and share common modifiable risk factors with obesity such as excess sugar intake. However, prioritization by governments to improve population oral health has been limited and is typically excluded from the discourse of public health policy development. Therefore, interventions that target dental caries can have other co-benefits including obesity prevention. In Victoria, Australia, local government authorities have a regulatory requirement to develop their Municipal Health and Wellbeing Plans. The aim of this paper is to identify whether prioritization for oral health by local government authorities in Victoria has changed through the subsequent renewal of the Victorian Public Health and Wellbeing Plans 2011-2015 and 2019-2023. Three desktop audits for all publicly available Municipal Health and Wellbeing Plans by local government authorities in Victoria were conducted between 2014 and 2022. Key terms related to oral health was searched within these policy documents and categorized into six indicators: (i) included oral health as a priority, (ii) linked healthy eating and oral health, (iii) supported the Achievement Program, (iv) included the Smiles 4 Miles program, (v) advocated for fluoridated drinking water, and (vi) included other strategies related to oral health. Overall, there was statistically significant reduction in five of the six indicators, with the exception for prioritization of other strategies related to oral health such as targeting excess sugar intake and smoking. A multi-sectoral approach, that includes oral health would be advantageous to address the growing burden of non-communicable diseases.

Has the Child Dental Benefits Schedule improved access to dental care for Australian children?

The Child Dental Benefits Schedule (CDBS) is an ongoing scheme administered through the Australian Government providing eligible children funding for clinical dental treatment. This study aimed to investigate the access of dental services across children's early childhood and examine whether the CDBS has improved access to dental care. The longitudinal study of Australian children is an ongoing cross-sequential cohort study with a representative sample of Australian children recruited in 2004. Birth (0-1 year) and kindergarten (4-5 years) cohorts were recruited through Medicare enrolment information at baseline and were representative of the Australian child population. Population-weighted longitudinal mixed effects Poisson models with individual identifiers as a random effect were used to assess the effect of Medicare dental schedules on reported dental attendance. Prior to the implementation of the CDBS for both cohorts, the birth cohort reported the lowest attendance rate at age 4-5. The introduction of the CDBS increased the rate of dental attendance for the low household income group by 8% (95% CI: 1%, 15%) after adjusting for confounders. The model provides evidence that dental attendance increased with age and the Indigenous population have 31% (95% CI: 4%, 55%) lower attendance rate after adjustment. The increase in reported access to dental services and favourable visiting patterns in low-income households during the operation of the CDBS provides some evidence that the schedule's primary aims to improve access to care in the child population are being met. Access to healthcare is multifaceted and the underutilisation of the schedule in the population warrants review of the schedule performance using other patient-centred indicators.
