Association Between Dental Expenditure and Socioeconomic Status in Iran.

BACKGROUND: Health care spending by households can be a great indicator of a society's commitment to good health stewardship and the efficiency of institutions responsible for managing health costs. Equitable and appropriate distribution of dental services is a challenging issue for realising universal health coverage. This study aimed to evaluate Iranian households' per capita dental expenditure (DE) according to their socioeconomic status (SES). METHODS: In this cross-sectional study, the income and expenditure of 18,701 urban and 19,261 rural households in Iran were scrutinised according to the data provided by the Statistics Center of Iran (2017-2018). After model creation, the SES index was determined using principal component analysis and weighting based on the analytical hierarchy process. The dependent variable was the share of per capita household's expenditure spent on dental health. The zero-inflated gamma regression model was applied to confirm the presumed association between per capita DE and SES. Analyses were performed using PROC NLMIXED in SAS software (version 4.9). RESULTS: The results revealed that approximately 9% of urban and 4% of rural households paid for dental treatments in the past month. The DE to total health expenditure (HE) ratios were 8.5% and 14.8% for rural and urban households, respectively. Also, with each level increase in SES, the average per capita DE increased by 23% and 16% in rural and urban households, respectively. CONCLUSIONS: The study confirms association between per capita DE and SES in Iran. This implies targeted strategies to facilitate the utilisation of dental care especially for lower SES groups according to their needs.

Painless cost control as a central strategy for universal oral health coverage: A critical review with policy guide.

AIM: This study aimed to critically review the methods used to control the significantly increasing costs of dental care. METHODS: Through a comprehensive search of the available literature, the cost control (CC) mechanisms for health services were identified from a healthcare system perspective. The probable applicability of each CC method was evaluated mainly based on its potential contribution to oral health promotion. Each mechanism was then classified and discussed under any of the two headings of financing and service provision. An operational guide was finally presented for policy-making in each of the three main models of healthcare systems, including National Health Services, social/public health insurance and private insurance. RESULTS: From a total of 142 articles/reports retrieved in PubMed, 73 in Scopus and 791 in Google Scholar, 35 were included in the final review after eliminating the duplicates and screening process. Totally ten mechanisms were identified for CC of dental care. Seven were discussed under the financing function, including cost sharing, preauthorization, mixed payment method and an evidence-based approach to benefit package definition, among others. Three further methods were classified under the service provision function, including workforce skill mix with emphasis on primary oral healthcare providers, development of primary healthcare (PHC) network and an appropriate use of tele-dentistry. CONCLUSION: Painless control of dental expenditures requires a smart integration of prevention into the CC plans. The suggested policy guide emphasizes organizational factors; particularly including the development of PHC-based networks with midlevel providers (desirably extended-duty dental hygienists) as the frontline oral healthcare providers.

Understanding why oral health professionals migrate: A qualitative investigation of Iranian dentists who have moved to Canada (Oral health professionals' migration).

BACKGROUND: The migration of health professionals from Low- and Middle-Income Countries (LMICs) to High-Income countries (HICs) is an ongoing phenomenon that has been accelerating with globalisation. While there has been growing research around the migration of physicians and nurses, there is less understanding of the motives surrounding the migration of dentists, and even less about their migration from specific countries. OBJECTIVES: This qualitative study explores the migration motivations of Iranian dentists who have moved to Canada. METHODS: Semi-structured interviews of 18 Iranian-trained dentists in Canada were conducted to obtain information about their motives for migration. Interviews were coded and categorised into themes using qualitative thematic analysis. RESULTS: Motivations to migrate were grouped into four analytical areas: socio-political; economic; professional; and personal. An inverse relationship was identified between the strongest motives to migrate and the topics respondents were least comfortable discussing. Socio-political-related motives were predominant with respondents focusing on their dissatisfaction with the social ethos and restrictions on personal freedom within Iran. CONCLUSION: Country-specific context is critical to fully understand health professional migration; in particular, the dynamics and interplay between socio-political, economic, and professional/personal factors within the home country. While Iranian dentists' motives to migrate have some similarities to other health professionals who migrated from Iran, and dentists from other countries, differences need to be considered to fully understand migration patterns.

The impact of sugar-sweetened beverages tax on oral health-related outcomes: a systematic review of the current evidence.

Objective To provide a systematic overview of the impact of taxing sugar-sweetened beverages (SSBs) on oral health-related outcomes.Data sources For this PRISMA-compliant review, we searched PubMed, Scopus, Embase, Web of Science and Cochrane Central for relevant studies published from database inception to 27 August 2020.Data selection and extraction Two reviewers assessed the abstracts and then the full text of the studies. Primary studies that evaluated the impact of any kind of SSB tax on oral health-related outcomes (that is, decayed, missing and filled teeth, caries increment and dental treatment costs) were included.Data synthesis Of 503 search results, five studies met the inclusion criteria. All five were modelling studies, from which four studies predicted an SSB tax to have a positive impact on oral health-related outcomes, whereas one study in a developing country did not find an SSB tax to be solely successful. According to three studies, the younger population and men are likely to benefit the most from such a tax. One study demonstrated the benefits of an SSB tax to be potentially more significant among low-income individuals.Conclusion While no empirical studies are available to support the benefits of an SSB tax, the studies covered in this review altogether anticipate a positive impact. Furthermore, this review discusses some of the obstacles and limitations of implementing such a tax predicted by the included studies.

Thematic analysis of the policies of Iran's health higher education.

BACKGROUND: In 1985, the Iranian parliament approved the integration of Medical Education and Health Services and the establishment of the Ministry of Health and Medical Education, which has since been the policymaker of Health Higher Education in Iran. The policies are not based on a codified framework and many were abolished at some point. Some critical issues are not addressed and some activities overlap. The purpose of the present study was to identify the content themes of core policies in the Iranian Health Higher Education system and provide a detailed policy orientation taxonomy. MATERIALS AND METHODS: This qualitative study was conducted in 2019 using the thematic content analysis of documents relevant to Higher Education and Health Higher Education, including upstream documents, and documents and enactments of the Deputy Minister of Education and its policy centers. RESULTS: From 586 policy documents, six main themes or six core policy orientations in the Health Higher Education System were identified, including Development of Medical Education System Policies; Ensuring the Alignment of Operations with Policies; Policies Related to Medical Education Development; Value-orientation; Networking and Development of Medical Education System Interactions; and the Development of Research, Management, and Translation of Medical Education knowledge. CONCLUSION: Developing a taxonomy of Health Higher Education policy orientations helps policymakers identify the neglected and overstressed areas. It can provide education policymakers with categorized and comprehensive information to quickly access accurate information, make informed decisions, avoid mistakes, and increase productivity.

Parents' preferences for preventive and curative dental services: A comparison between fissure sealant and composite filling using willingness-to-pay method.

BACKGROUND: The early years of life play a significant role in the lifelong health of humans and parents have an important role in healthcare decision making. Thus, it seems necessary for policymakers and clinicians to be aware of how parents value pediatric health services. Willingness to pay (WTP) is a recommended method for measuring the stated utility of health services/goods or health states. AIM: This study aimed to elicit and compare parents' WTP for health services such as fissure sealant and composite filling. DESIGN: An originally developed questionnaire was used to guide interviews with a sample of 290 parents attending a public pediatric healthcare center. Related-samples Wilcoxon signed-rank test was performed for comparing the difference in absolute WTP amounts between the two services, and linear regression was used to assess the association between WTP and relevant variables using SPSS version 21. RESULTS: Mean WTP for fissure sealant and filling was 269 724 and 555 327 Tomans, respectively, and the difference between them was statistically significant (P < .001). Higher WTP amounts found in both services were associated with income levels of 4 and 5 (P < .05). CONCLUSIONS: Respondents highly valued the considered services and stated a significantly higher relative preference for filling. Public awareness should be promoted about the importance of prevention of oral health diseases and the attributes of the oral healthcare system services.

An overview of the methodological aspects and policy implications of willingness-to-pay studies in oral health: a scoping review of existing literature.

BACKGROUND: Demands for dental services seem to be beyond the capacities of most healthcare systems these days. Patient preferences have been increasingly emphasized to be considered in the joint decision-making process. Willingness-to-pay (WTP) is a recommended method for measuring the utility of health services; increasingly being used in recent decades. Taking these points into consideration, this article aims to provide an overview of the methodological aspects and policy implications of WTP studies in the field of oral health. METHODS: The research was conducted in ISPOR, PubMed and Google Scholar databases. In addition, reference lists of included articles were checked to identify the relevant studies. All studies published were included that were in the English language and reported using WTP for oral health-related goods and services. A data-charting form was developed by a focus group discussion panel of seven experts to derive the main methodological aspects of WTP. Also, Core policy suggestions were categorized through thematic content analysis of the included papers. RESULTS: The search strategy yielded 389 studies of which 52 were included. WTP studies in oral health show an increasing trend in global publications. The UK and Canada have a greater share in published material than in any other country. The dominant field of these researches is in restorative and prosthetic dentistry, and a wide range of different methodological aspects was documented. Policy suggestions were categorized in three main themes: (A) setting new tariffs or subsidizing the item, (B) provision of the item due to population preferences, and (C) improving literacy regarding the item. CONCLUSIONS: An urgent need for a common framework regarding the design of WTP studies in dentistry seems paramount. Some policy suggestions seem not to be applicable, perhaps due to insufficient familiarity of the researchers with the complexities of the public policymaking process.

Commentary: Necessity of Blending Dental Education Into the Mainstream of Medical Education as a Specialty Area: Advocating for a Reform Idea Aiming to Promote the Health System Performance in Iran.

With the knowledge we have today about the concept of health and its complexities and determinants, the separation between medical and dental education (DE) does not seem reasonable anymore. Dentistry has mainly developed based on a mechanical approach to treat the related problems. This makes the efforts for reorientation of dental care (DC) toward a preventive approach, relying upon dentists as the chief oral health (OH)-related workforce, inefficient. This is while effective strategies have been identified for prevention, as the key to simultaneously control the burden and costs of the ubiquitous oral diseases, at both individual and population levels without dentists. We think that approaching OH as an integral part of the general well-being requires fundamental changes in the structure of OH system including a substantial revision in the current situation of dentistry as an autonomous health profession with a separate education from the main body of the medicine. In this short article, we briefly discuss the necessity of blending DE into the mainstream of medical education and actual consideration of dentistry as a medical specialty area. After discussing the subject at two levels (health-care system and national levels), the next sections draw attention to some complementary issues.

Measurement components of socioeconomic status in health-related studies in Iran.

OBJECTIVE: The socioeconomic status (SES) is as a symbol of social determinants of health which has a dominant influence on population health. The purpose of this study was collecting, weighing, and determining the most relevant SES measurement items in Iran. RESULTS: The SES health studies conducted in Iran was searched from 2007 to 2017. First, the SES items were categorized. Then, each item was weighed based on its reliability and generalizability. Finally, the necessity of items was determined, weighed, and ranked. This is the two-round Delphi technique. After weighing 57 SES items, 37 items were selected with ≥ 1 weight and classified in 7 categories. According to the Delphi evaluation, 15 items were identified ≥ 3.5 for measuring SES of Iranian households: household size, head of household education, head of household job, household monthly income, type of school that children attend, house ownership, local value of residence, number of rooms in the house, house area, personal computer/laptop, smart cell phone, 3D TV, dishwasher, microwave, and car ownership. The SES items for the present society are categorized in 7 domains. The items collected in this study have the most comprehension of all studies related to income, life facilities, and assets.

Developing a decision support system to link health technology assessment (HTA) reports to the health system policies in Iran.

The recent increase of 'Health Technology Assessment' (HTA)-related activities in Iran has necessitated the clarification of policy-making process based on the HTA reports. This study aimed to develop a Decision Support System (DSS) in order to adopt evidence-informed policies regarding health technologies in Iran. The study can be classified as Health Policy and Systems Research. A core panel of seven experts conducted two separate reviews of relevant literature for: 1- Determining the potential technology-related policies. 2- Listing the criteria influencing those policy decisions. The policies and criteria were separately discussed and subsequently rated for appropriateness and necessity during two expert meetings in 2013. In the next step, The 'Discrete Choice Experiment' (DCE) method was employed to develop the DSS for the final technology-related policies. Accordingly, the core panel members independently rated the appropriateness of each policy for 30 virtual technologies based on the random values assigned to all the criteria for each technology. The obtained data for each policy were separately analysed using stepwise regression model, resulting in a minimal set of independent and statistically significant criteria contributing in the experts' judgments about the appropriateness of that policy. The obtained regression coefficients were used as the relative weights of the different levels of the final criteria of any policy statement, shaping the decision support scoring tool for each policy. The study has outlined 64 policy decisions under 7 macro policy areas concerning a health technology. Also, 34 criteria used for making those policy decisions have been organized within a portfolio. DCE, using stepwise regression, resulted in 64 scoring tools shaping the DSS for all HTA-related policies. Both the results and methodology of the study may serve as a guide for policy makers (researchers), particularly in low and middle income countries, in developing decision aids for their own context-specific HTA-related policies.

Health Technology Assessment of CEM Pulpotomy in Permanent Molars with Irreversible Pulpitis.

INTRODUCTION: Teeth with irreversible pulpitis usually undergo root canal therapy (RCT). This treatment modality is often considered disadvantageous as it removes vital pulp tissue and weakens the tooth structure. A relatively new concept has risen which suggests vital pulp therapy (VPT) for irreversible pulpitis. VPT with calcium enriched mixture (VPT/CEM) has demonstrated favorable treatment outcomes when treating permanent molars with irreversible pulpitis. This study aims to compare patient related factors, safety and organizational consideration as parts of health technology assessment (HTA) of the new VPT/CEM biotechnology when compared with RCT. MATERIALS AND METHODS: Patient related factors were assessed by looking at short- and long-term clinical success; safety related factors were evaluated by a specialist committee and discussion board involved in formulating healthcare policies. Organizational evaluation was performed and the social implications were assessed by estimating the costs, availability, accessibility and acceptability. The impact of VPT/CEM biotechnology was assessed by investigating the incidence of irreversible pulpitis and the effect of this treatment on reducing the burden of disease. RESULTS: VPT/CEM biotechnology was deemed feasible and acceptable like RCT; however, it was more successful, accessible, affordable, available and also safer than RCT. CONCLUSION: When considering socioeconomic implications on oral health status and oral health-related quality of life of VPT/CEM, the novel biotechnology can be more effective and more efficient than RCT in mature permanent molars with irreversible pulpitis.

Social insurance for dental care in Iran: a developing scheme for a developing country.

AIMS: This study aimed to describe the current situation with regard to dental care provided under social insurance in Iran in qualitative terms and to assess it critically with regard to equity and efficiency. METHODS: After a thorough review of the relevant literature, a template of topics, which included population coverage, range of treatment provided, contracting mechanisms, fees, level of co-payments and dental share of total health expenditures, was developed by a panel of Iranian health finance experts. It was used during interviews with informed persons from the different Iranian social funds. These interviews were recorded and transcribed. The transcriptions were checked for accuracy by those who had been interviewed and were then analysed. RESULTS: It was found that, currently, four major social funds are involved in health (including dental) insurance in Iran, under the supervision of The Supreme Council of Health Insurance, located at the newly integrated Ministry of Cooperatives, Labour & Social Welfare. Around 90% of Iranians are covered for health insurance within a Bismarckian system to which the employed, the employers, and the Government contribute. The system has developed piecemeal over the years and is characterised by a complexity of revenue-collection schemes, fragmented insurance pools, and passive purchasing of dental services. CONCLUSIONS: The dental sector of Iranian social insurance should establish a strategic purchasing plan for dental care with the aim of improving performance and access to care. Within the plan, there should be a basic benefit package of dental services based on the relative cost-effectiveness of interventions, educating an adequate number of allied dental professionals to provide simple services, and introducing mixed payment methods.
