Dental expenditure and catastrophic dental expenditure in Eastern Saudi Arabia: Pattern and associated factors

Oral health approach in universal health coverage

OBJECTIVE

This study aimed to map how oral health is addressed within the universal health coverage (UHC).

METHODS

This scoping review followed the Joanna Briggs Institute methodology. Searches included the WHO Library and PubMed, Scopus, Embase, LILACS, and Cochrane databases. Quantitative and qualitative studies were included without publication date and language restrictions.

RESULTS

A total of 486 studies were retrieved, of which 292 were excluded in the title and abstract screening phase; 121 full-texts were assessed. After the removal of duplicates and unavailable documents, 50 studies were included in the review and categorized according to the level of scientific evidence.

CONCLUSION

Few studies discussed oral health within the UHC, mostly because this coverage does not include oral health adequately. When offered, oral health packages are limited and include specific populations. Access and use of oral health services remain guided by economic factors, exposing the theoretical financial protectionism that perpetuates health inequalities.

Catastrophic out-of-pocket payments for dental treatment: regional evidence from Spain

BACKGROUND

To estimate the incidence and concentration of catastrophic out-of-pocket payments for healthcare and dental treatment, by region in Spain (calculated as the proportion of households needing to exceed a given threshold of their income to make these payments) in 2008, 2011 and 2015.

METHODS

The data analysed were obtained from the Spanish Family Budget Survey reports for the years in question. The study method was that proposed by Wagstaff and van Doorslaer (2003), contrasting payments for dental treatment versus household income and considering thresholds of 10%, 20%, 30% and 40%, thus obtaining incidence rates. In addition, relevant sociodemographic variables were obtained for each household included in the study.

RESULTS

With some regional heterogeneity, on average 4.75% of Spanish households spend more than 10% of their income on dental treatment, and 1.23% spend more than 40%. Thus, 38.67% of catastrophic out-of-pocket payments for dental services in Spain corresponds to payments at the 10% threshold. This value rises to 55.98% for a threshold of 40%.

CONCLUSIONS

An important proportion of catastrophic out-of-pocket payments for health care in Spain corresponds to dental treatment, a service that has very limited availability under the Spanish NHS. This finding highlights the need to formulate policies aimed at enhancing dental cover, in order to reduce inequalities in health care and, consequently, enhance the population's quality of life and health status.

Catastrophic household expenditure associated with out-of-pocket payments for dental healthcare in Spain

OBJECTIVE

To estimate the prevalence of catastrophic health expenditure due to dental healthcare (CHED) in Spain, quantify its intensity and examine the related sociodemographic household characteristics.

METHODS

Data from the Spanish Household Budget Survey, which addresses more than 20,000 households each year for the period 2008-2015 were included, and the methodology proposed by Wagstaff and van Doorslaer was followed. The prevalence (number of households that devote more than a certain threshold of their income to such payments) and intensity (amount that exceeds a certain percentage of income) were estimated. Ordered logistic regression models were estimated to analyse the sociodemographic factors associated with the prevalence of catastrophic payments.

RESULTS

The prevalence and intensity remained stable during the period under analysis. In terms of prevalence, a mean proportion of 7.36% of the population dedicated, in terms of intensity, more than 10% of their resources to dental care payments [mean: €292.75 per year (SD €2144.14)] and 2.05% dedicated more than 40% [mean: €143.02 per year (SD €1726.42)]. This represents 36.32% and 51.34% (for the thresholds of 10% and 40%) of the total catastrophic expenditure derived from out-of-pocket payments for dental healthcare in Spain.

CONCLUSION

This study shows that a significant proportion of catastrophic healthcare payments correspond to dental services. Being male, aged over 40 years, unattached (single, separated, divorced or widowed), having a low level of education, a low household income, being unemployed and living in an urban area are all associated with a greater risk of CHED. This finding highlights the need to establish policies aimed at increasing dental care coverage to mitigate related financial burdens on a large part of the Spanish population.

Socioeconomic inequalities in the utilization of dental services among adults in Saudi Arabia

Background

This study used the Anderson Behavioral Model to assess the socioeconomic inequalities in dental services utilization among adults in Saudi Arabia, along with other predictors of utilization, to inform future planning of dental care services.

Methods

This cross-sectional study was a secondary analysis using national data from the 2019 Kingdom of Saudi Arabia World Health Survey (KSAWHS). The survey consisted of two interviewer-administered questionnaires: one household and one individual interview. The questions covered predisposing factors (age, gender, marital status, nationality, education, employment), enabling factors (income, household wealth, area-based socioeconomic class, health insurance, eligibility for free governmental health care, transportation and region of residence) and self-reported need for dental treatment. The main outcome was dental utilization in the past year; predisposing, enabling and need factors were independent variables. Hierarchical logistic regression analyses identified significant predictors of dental utilization, applying survey weights to adjust for the complex survey design. Adjusted odds ratios with 95% confidence intervals and p values were reported in the final model.

Results

The final dataset included 8535 adults (response rate = 95.4%). Twenty percent of adults had visited the dentist at least once in the past year (95% CI 18–21%). There were socioeconomic inequalities in dental utilization. High household income (OR 1.43, p = 0.043), second and middle household wealth status (OR 1.51, p = 0.003 and OR 1.57, p = 0.006) and access to free governmental health care (OR 2.05, p = 0.004) were significant predictors in the final regression model along with perceived need for dental treatment (OR 52.09, p < 0.001).

Conclusion

Socioeconomic inequalities in the utilization of dental services exist in Saudi Arabia. The need for treatment was the strongest predictor suggesting predominantly symptomatic attendance. Increasing awareness about the importance of preventive dental visits rather than symptomatic attendance could be an important policy implication to improve oral health and optimize dental care expenditure. Further research should explore the drivers for adults to seek preventive care in the absence of any recognized dental problems.
