Estimating Attribute-Specific Willingness-to-Pay Values from a Health Care Contingent Valuation Study: A Best-Worst Choice Approach.

BACKGROUND: Willingness-to-pay (WTP) studies frequently use a contingent valuation (CV) method to determine the economic value of a good or service. However, a typical CV study is able to estimate the WTP for a good as a whole, but provides no information about the marginal WTP for different attributes of a good. OBJECTIVE: The aim was to estimate marginal WTP for different attributes of a CV scenario. METHODS: By using the data from an additional best-worst choice (BWC) experiment, we disaggregated the holistic WTP values for dental care, estimated using the CV method, into attribute-specific WTP values. The study was conducted at the School of Dental Medicine, University of Zagreb, Croatia. Dental school patients were surveyed from March 2016 to January 2017, and their WTP for dental care was estimated using either a CV survey (n = 242), which also included a BWC task, or a discrete choice experiment (DCE) survey (n = 275). RESULTS: The largest marginal welfare estimate (€13.5) was obtained for the improvement in treatment explanation, followed by the improvements in staff behavior (€8.1) and waiting time in the office (€7.2), and by the changes in dental care provider (€3.4). These estimates were generally highly similar to the traditional marginal WTP estimates obtained with a traditional multi-profile DCE, after adjusting DCE estimates for non-attendance to the cost attribute. CONCLUSION: Our BWC-CV framework may serve as a valuable alternative for estimating marginal WTP values for health care attributes when the choice behavior of respondents raises concerns for the validity of DCE estimates.

Population-centered Risk- and Evidence-based Dental Interprofessional Care Team (PREDICT): study protocol for a randomized controlled trial.

BACKGROUND: To improve the oral health of low-income children, innovations in dental delivery systems are needed, including community-based care, the use of expanded duty auxiliary dental personnel, capitation payments, and global budgets. This paper describes the protocol for PREDICT (Population-centered Risk- and Evidence-based Dental Interprofessional Care Team), an evaluation project to test the effectiveness of new delivery and payment systems for improving dental care and oral health. METHODS/DESIGN: This is a parallel-group cluster randomized controlled trial. Fourteen rural Oregon counties with a publicly insured (Medicaid) population of 82,000 children (0 to 21 years old) and pregnant women served by a managed dental care organization are randomized into test and control counties. In the test intervention (PREDICT), allied dental personnel provide screening and preventive services in community settings and case managers serve as patient navigators to arrange referrals of children who need dentist services. The delivery system intervention is paired with a compensation system for high performance (pay-for-performance) with efficient performance monitoring. PREDICT focuses on the following: 1) identifying eligible children and gaining caregiver consent for services in community settings (for example, schools); 2) providing risk-based preventive and caries stabilization services efficiently at these settings; 3) providing curative care in dental clinics; and 4) incentivizing local delivery teams to meet performance benchmarks. In the control intervention, care is delivered in dental offices without performance incentives. The primary outcome is the prevalence of untreated dental caries. Other outcomes are related to process, structure and cost. Data are collected through patient and staff surveys, clinical examinations, and the review of health and administrative records. DISCUSSION: If effective, PREDICT is expected to substantially reduce disparities in dental care and oral health. PREDICT can be disseminated to other care organizations as publicly insured clients are increasingly served by large practice organizations. TRIAL REGISTRATION: ClinicalTrials.gov NCT02312921 6 December 2014. The Robert Wood Johnson Foundation and Advantage Dental Services, LLC, are supporting the evaluation.

An Australian government dental scheme: Doctor-dentist-patient tensions in the triangle.

UNLABELLED: Autonomy of participants is challenged when legislation to provide a public health service is weakly designed and implemented. BACKGROUND: Australia's Chronic Disease Dental Scheme was instigated to provide a government subsidy for private dental treatment for people suffering chronic illness impacting their oral health or vice versa. They were allocated AUD$4250 towards comprehensive treatment over 2 years with their eligibility determined by their general medical doctor. RESEARCH: A qualitative research study was conducted to explore the experiences from the perspectives of the patient, medical and dental practitioner. One of the research outcomes identified a frequently reported level of discomfort in the patient/doctor/dentist triangle. Doctors and dentists reported feeling forced by patients into positions that compromised their autonomy in obeying the intent (if not the law) of the scheme. Additionally, dentists felt under pressure from doctors and patients to provide subsidized treatment to those eligible. In turn, the patients reported difficulties in gaining access to the scheme and in some cases, experiencing full or partially unmet oral health needs. REASON FOR CONFLICT: Poor inter-professional communication and lack of understanding about profession-unique patient-driven pressures, ultimately contributed to dissonance. Ill-defined eligibility guidelines rendered the doctor's ability to gate-keep challenging. OUTCOME OF CONFLICT: Inefficient gate-keeping led to exponential increase in referrals, resulting in unprecedented cost blow-outs. Ensuing government-led audits caused political tensions and contributed to the media-induced vilification of dentists. In December 2013, government financing of dental treatment through Chronic Disease Dental Scheme was discontinued, leaving many Australians without a viable alternative. RECOMMENDATIONS: There is a need for qualitative research methods to help identify social issues that affect public health policy process. In order to succeed, new health policies should respect, consider and attempt to understand the autonomy of key participants, prior to and throughout.

Community dental clinics: providers' perspectives.

OBJECTIVES: Not-for-profit community dental clinics attempt to address the inequities of oral health care for disadvantaged communities, but there is little information about how they operate. The objective of this article is to explain from the perspective of senior staff how five community dental clinics in British Columbia, Canada, provide services. METHODS: The mixed-methods case study included the five not-for-profit dental clinics with full-time staff who provided a wide range of dental services. We conducted open-ended interviews to saturation with eight senior administrative staff selected purposefully because of their comprehensive knowledge of the development and operation of the clinics and supplemented their information with a year's aggregated data on patients, treatments, and operating costs. RESULTS: The interview participants described the benefits of integrating dentistry with other health and social services usually within community health centres, although they doubted the sustainability of the clinics without reliable financial support from public funds. Aggregated data showed that 75% of the patients had either publically funded or no coverage for dental services, while the others had employer-sponsored dental insurance. Financial subsidies from regional health authorities allowed two of the clinics to treat only patients who are economically vulnerable and provide all services at reduced costs. Clinics without government subsidies used the fees paid by some patients to subsidize treatment for others who could not afford treatment. CONCLUSIONS: Not-for-profit dental clinics provide dental services beyond pain relief for underserved communities. Dental services are integrated with other health and community services and located in accessible locations. However, all of the participants expressed concerns about the sustainability of the clinics without reliable public revenues.

Hospitalisations for removal of impacted teeth in Australia: a national geographic modeling approach.

INTRODUCTION: The aim of the study was to project hospitalisation rates for the surgical removal of impacted teeth across Australia, based on Western Australian statistics. METHODS: Population data were obtained from the Australian Bureau of Statistics and were divided across Australia by statistical local area and related to a validated socioeconomic index. Every episode of discharge from all hospitals in Western Australia for the financial years 1999/2000 to 2008/2009 indicating an impacted/embedded tooth removal as the principle oral condition, as classified by the International Classification of Disease (ICD-10AM), was included in the study. Hospitalisation data were obtained from the Western Australian Hospital Morbidity Data System. Variables of age, place of residence and health insurance status were utilised for projecting the Western Australian rates across Australia. RESULTS: The results of the study showed a definite rural-urban divide and the estimated age-adjusted rates were almost three times greater in the higher socioeconomic areas when compared to their poorer counterparts. The costs of the procedure were estimated to be approximately $60 million per annum across Australia. CONCLUSION: The findings of this study can be used to inform health policy to guide proper allocation of resources and target services for the benefit of the community especially those residing in rural and remote areas in a vast country like Australia.

Industry structures in private dental markets in Finland.

OBJECTIVE: To use industrial organisation and organisational ecology research methods to survey industry structures and performance in the markets for private dental services and the effect of competition. DESIGN: Data on practice characteristics, performance, and perceived competition were collected from full-time private dentists (n = 1,121) using a questionnaire. The response rate was 59.6%. Cluster analysis was used to identify practice type based on service differentiation and process integration variables formulated from the questionnaire. RESULTS: Four strategic groups were identified in the Finnish markets: Solo practices formed one distinct group and group practices were classified into three clusters Integrated practices, Small practices, and Loosely integrated practices. Statistically significant differences were found in performance and perceived competitiveness between the groups. Integrated practices with the highest level of process integration and service differentiation performed better than solo and small practices. Moreover, loosely integrated and small practices outperformed solo practises. Competitive intensity was highest among small practices which had a low level of service differentiation and was above average among solo practises. CONCLUSIONS: Private dental care providers that had differentiated their services from public services and that had a high number of integrated service production processes enjoyed higher performance and less competitive pressures than those who had not.

Complete denture services: clinical technique, lab costs, manpower, and reimbursement. One-year review.

Complete denture services at comprehensive care public health clinics are not common in part because of clinician concerns regarding outcomes. Educational debt forgiveness has attracted recent dental graduates to public health dentistry; however, not all recent graduates receive denture education experiences necessary to attain proficiency. While fundamental patient assessment and denture construction are taught, psychological assessment and communication with denture patients requires experience. A thorough understanding of occlusion, phonetics, esthetics and laboratory steps is also necessary. Expecting recent dental graduates to become proficient providing complete dentures at minimal reimbursement levels, with no mentorship or on-site laboratory support, is unrealistic. Public health dental clinics operate at full capacity performing emergency, preventive and restorative procedures. Complete dentures come with a laboratory fee approximately one-half the total reimbursement, meaning a remake drops clinic revenue to zero while doubling expenses. It is understandable that full schedules, marginal reimbursement, unpredictability and the risk of an occasional failure block clinician interest in providing denture services. This one-year report of services describes a three-appointment complete denture technique offering improved patient and laboratory communication, reduced chair time and controlled cost, resulting in high-quality complete dentures.

Management and marketing for the general practice dental office.

This article reviews trends in the dental marketplace. Marketing is an essential element of dentistry. Communicating treatment options with patients is one aspect of marketing. Treatment planning helps patients understand the relationships between oral health, occlusion, temporomandibular joint function, and systemic health. Through marketing, dental practice owners inform patients of ever-changing treatment modalities. Understanding treatment options allows patients to make better, informed choices. More options leads to a higher level of care and more comprehensive dental treatment. Managing a practice requires tracking its financial health. Economic statistics measure the effect of management decisions that mark the direction of a dental practice.

Why do we need an oral health care policy in Canada?

Although health care is a right of citizenship, severe inequities in oral health and access to care persist. This paper provides information on the financing, organization and delivery of oral health services in Canada. It concludes that dental care has largely fallen out of consideration as health care. The increasing costs of dental insurance and disparities in oral health and access to care threaten the system"s sustainability. The legislation that allows the insured to receive tax-free care and requires all taxpayers to subsidize that expenditure is socially unjust. Unless an alternative direction is taken, dentistry will lose its relevance as a profession working for the public good and this will be followed by further erosion of public support for dental education and research. However, never before have we had the opportunity presented by high levels of oral health, the extensive resources already allocated to oral health care, plus the support of other organizations to allow us to consider what else we might do. One of the first steps would be to establish new models for the delivery of preventive measures and care that reach out to those who do not now enjoy access.

More attention to public health in the European Union - implications for dentistry?

At present the European Union is developing its competence on health and new important issues will be taken on board in European health policy. Increasing mobility of people and integration of the applicant countries puts pressure on the current health care provision systems. A mandate for an open co-ordination process in public health is expected to be given by the European Council. The process will start by exchange of information and best practice models. The next step will be the presentation of common targets between member countries, followed by national action programmes and indicators. It is likely that a lot of emphasis will be put on access to health services, comparisons of costs of health care and benchmarking the costs of items of care. In the long run this will mean convergence of the health care systems. If oral health is to be considered an integral part of general health dental professionals need to be aware of and be able to influence the actions to be taken.

Dental care needs and demands in patients attending the dental hospital of the Obafemi Awolowo University Teaching Hospital's Complex Ile-Ife, Nigeria.

BACKGROUND: To compare the pattern of need and demand for dental care in settings where services are paid for through government sponsored insurance programs and out of pocket by individuals. METHODS: Study consisted of first visit patients attending the Dental Hospital. The assessment of normative treatment needs was done. The tooth based treatment needs were assessed by the WHO basic methods and the periodontal needs were assessed by the periodontal need systems PTNS. RESULTS: More males had sought treatment than females. In both sexes, most of the patients demanding treatment belonged to the 17-34 year age group. There was no statistically significant difference between age groups (P = 0.65). 55.4, 8.1 and 1.4 percents sought care for toothache, caries without concomitant pain and dental check-up respectively. Oral surgical care was considered necessary for the main complaint in 50.1% of cases. However, the age group 17-34 year old needed more restorative care than periodontal and the > 65 age group requested more extractions. CONCLUSION: The expressed need or demand for dental care falls short of the normative need. It should therefore be the aspiration of appropriate government ministry and health care providers to attempt converting normative needs into demand for care.

Oral healthcare systems in the extended European union.

UNLABELLED: This article reports a survey of the systems for the provision of oral healthcare in the 28 member and accession states of the EU/EEA in 2003. Descriptions of the systems were collected from the principal dental advisers to governments in the individual states. In many states these were the Chief Dental Officers (CDOs). In states without a CDO, descriptions were gathered from CDO equivalents or senior academics. A template (model description) was used to guide all respondents. Additional statistical information on oral healthcare costs and workforce was collected from the Council of European Chief Dental Officers, WHO and World Bank websites. The study showed that in broad terms there were six patterns (Beveridgian, Bismarkian, The Eastern European (in transition), Nordic, Southern European and Hybrid) for the administration and financing of oral healthcare in the expanding EU. The extent and nature of government involvement in planning and coordinating oral healthcare services and the numbers and pay of the oral healthcare workforce varied between the different models. The biggest recent changes in European oral healthcare were found to have occurred in Eastern Europe, where there has been wide scale privatization of the previously public dental services. However, most of the EU accession (Eastern European) states seemed to be slowly developing insurance systems to cover oral health treatment costs. In the existing EU/EEA, the public dental services such as those in the Nordic countries still have strong political support and some expansion has occurred. In Southern Europe public dental services seemed to have gained some acceptance for the treatment of children and special needs groups. In UK, which has a unique public dental service system, there are plans to make big changes in the delivery, commissioning and remuneration of dental services in the near future. Some EU member states which operate the Bismarkian system with health insurances offering wide population coverage, comprehensive treatment and benefits connected with frequent dental visits, were reported to be experiencing financial problems. The study also indicated that at present, with the exception of Portugal and Spain, where there is dynamic growth in the numbers of dentists, the overall size of the EU/EEA oral health workforce is expanding fairly slowly. Only a minority of member states appeared to collect data on uptake of services and care costs and there were great difficulties in assessing outcomes of care. The data on costs appeared to show wide variations from member state to member state in per capita spending on oral healthcare. In the majority of states, however, costs, especially those in the private sector, could only be estimated. Nevertheless, at a 'macro' level, the study indicated that, in 2000, the 28 member and accession states of the EU/EEA had a total population of 456 million and an oral health workforce of 900,000 (some 300,000 of whom were dentists) and that the cost of oral healthcare was about EUR 54,000,000,000. CONCLUSION: The study showed wide variations in oral healthcare provision systems between EU/EEA member and accession states and no evidence of harmonization in the past.

Oral healthcare in transition in Eastern Europe.

Big changes have occurred in the oral healthcare delivery systems of most Eastern European countries since the fall of the Berlin wall in 1989 and the demise of communism in the former USSR in 1991. In the new situation it was necessary to reform the political and social systems including healthcare. Reforms were started to improve the economy and, in comparison with Western Europe, the generally lower living standards. It is difficult to obtain comprehensive data on oral healthcare in Eastern European countries but this paper reports data from nine countries and provides a 'macro' view of the current situation in these countries. Many countries seem to have adopted a Bismarckian model for the provision of oral healthcare based on a sickness insurance system.

A time-series analysis of caries status among adolescents in relation to socioeconomic variables in Göteborg, Sweden.

The aim of this study was to detect, using time-series analysis methods, whether measurable socioeconomic adjustments for the time period 1986-96, as presented by caries index values, could be related to a new trend in caries status development for specific age groups leaving the free state-organized dental care system. In the study, Göteborg was divided into four districts. The study showed a favorable development in dental health for the 15-19 age group. However, the caries incidence index DSa (decayed approximal surfaces) values showed no or only negligible signs of lower mean values. During the study period, the study showed an unfavorable trend concerning the socioeconomic variables related to health care. However, the incongruity for the different districts between the trend results of the caries index values and the contemporaneous socioeconomic variable development indicated few signs of relationship. In relation to general discussions of environmental questions, the idea of sustainable development was discussed when applied to the field of dental care. The results of this study indicate that dental health, in times of major economic adjustments and lack of resources for health care for the 15-19 age group in Göteborg--as interpreted by the caries indices used is an example of sustainable dental health development.

The dash for dentures: the turbulent introduction of NHS dentistry.

With the formal launch of the National Health Service on the evening of Sunday, July 4, 1948, the pattern of dental treatment in Britain changed dramatically. This change altered the lives of everyone connected with the provision of this treatment and, for dentists in particular, working life would never be the same again. But how did they come about?
