Impact of income and financial subsidies on oral health care utilization among persons with disabilities in Singapore.

BACKGROUND/AIM(S): Globally, studies have shown that the dental disease burden among persons with intellectual and/or developmental disabilities (IDD) is high and can be attributed to lower utilization levels of dental services. The aim of the study was to assess the influence of income and financial subsidies on the utilization of dental care services among persons with IDD in Singapore. METHODS: Between August 2020 and August 2021, a cross-sectional study was conducted via centres offering Early Intervention Programme for Infants and Children, special education schools and adult associations in Singapore serving persons with IDD. A sample of 591 caregivers of children and adults with IDD completed the survey. Data on sociodemographic information, oral health behaviours and dental utilization were collected. Financial subsidy status was assessed by the uptake of a government-funded, opt-in Community Health Assist Scheme (CHAS) for low-income families that provided a fixed subsidy amount for dental services in the primary care setting. Statistical analysis was carried out using univariable, multiple logistic regression and modified Poisson regression. Propensity score matching was carried out in R version 4.0.2 to assess the impact of financial subsidies on oral health care utilization among persons with IDD. RESULTS: Compared to those with lower gross monthly household incomes, the adjusted prevalence ratios of having at least one dental visit in the past year, having at least one preventive dental visit in the past year, and visiting the dentist at least once a year for persons with IDD with gross monthly household incomes of above SGD$4000 were 1.28 (95% CI 1.08-1.52), 1.48 (95% CI 1.14-1.92) and 1.36 (95% CI 1.09-1.70), respectively. Among those who were eligible for CHAS Blue subsidies (247 participants), 160 (62.0%) took up the CHAS Blue scheme and 96 (35.4%) visited the dentist at least yearly. There was no statistically significant difference in the utilization of dental services among individuals enrolled in the CHAS Blue subsidy scheme among those eligible for CHAS Blue subsidies. CONCLUSION: Higher household income was associated with a higher prevalence of dental visits in the past year, preventive dental visits in the past year, and at least yearly dental visits. CHAS Blue subsidies alone had limited impact on dental utilization among persons with IDD who were eligible for subsidies.

Dentists' perspectives on structural and system barriers hindering oral healthcare provision in residential care facilities.

OBJECTIVES: Oral healthcare service is not well integrated with existing healthcare policy in nursing homes (NHs) globally. This qualitative study aimed to identify dentists' perspectives on structural and system barriers that hinder oral healthcare (OHC) provision to seniors in NHs in Singapore and to understand the consequences of these barriers. METHODS: Nineteen dentists (8 males and 11 females, 36.0 [IQR: 32.0-48.5] years old) were recruited through combination of purposive and snowball sampling. Four focus group discussions were conducted via teleconferencing, and each discussion had 4-5 anonymised participants. Sessions lasted 90-120 min and were audio-recorded and transcribed verbatim. Thematic analysis was conducted on data collected using NVivo software (Version12, QRS International). RESULTS: Participants agreed that the current OHC system for seniors in NHs is not well developed. The challenges dentists faced were categorised in three themes: [1] general oral healthcare system level; [2] local nursing home setting level; and [3] geriatric oral healthcare education level. These challenges are complexly intertwined and have contributed to several consequences such as a shortage of dentists in NHs and their diminished motivation to serve. It has also limited the quality of dental service they are able to provide in NHs, contributing to the current poor access of dental services for seniors in NHs. CONCLUSIONS: Dentists in Singapore face many structural and systemic barriers in providing OHC to seniors in NHs, some of which are unique to the local context. Newfound understanding of these barriers and its consequences will be helpful in developing strategic approaches to overcome these challenges.

Addressing the overlooked: Integrating oral healthcare in a geriatric care system: Insights from Singapore.

Oral health of the older population has long been overlooked in global healthcare agenda. Limited access to oral healthcare for dependent older adults results in poor oral health, negatively impacting their quality of life, nutrition and overall well-being. Especially for nations experiencing rapid ageing population, efforts must be urgently made to integrate oral healthcare services into the current healthcare system and policy. Singapore stands out as one of the most rapidly ageing nations in Southeast Asia, achieving remarkable progress in the healthcare field, as well as advancements in social modernization and economic growth. It now faces the growing burden of the dependent older population and is required to respond to the complex challenges associated with providing holistic eldercare services and ensuring the well-being of its ageing population. This narrative review offers an overview of Singapore's current healthcare policy and system development for the older population, with a specific focus on oral healthcare. The goal is to shed light on this underexplored area, highlighting the challenges that need to be tackled to improve the accessibility of oral health services for dependent older adults.
