Importance of bitewing radiographs for the early detection of interproximal carious lesions and the impact on healthcare expenditure in Japan.

BACKGROUND: Globally, the direct cost of dental caries is approximately $298B yearly, consuming 5-10% of national healthcare budgets. Bitewing radiographs (BWR) are the standard method of diagnosing interproximal dental caries. In Japan, bitewing radiographs are rarely used. This retrospective observational study was conducted to measure the potential economic impact of carious lesions left undiagnosed and untreated due to this omission of bitewing radiographs. METHODS: The total number of existing carious lesions, the number of undiagnosed lesions, and costs of treating these lesions were calculated from the national database of Ministry of Health, Labor and Wellness in Japan between June 2013 and 2017. The number of affected teeth was estimated using prevalence data and undiagnosed lesions were estimated. The expense associated with treating progressed lesions was calculated using the standard Japanese fee structure. BWR trends were assessed, and analyses were performed to understand the differences between states and populations over time. RESULTS: The average number of BWR taken monthly per office was 48.3±1.1 (average ± SD). It was calculated that an average of 6,429,155 lesions went undiagnosed per month, 93.5 teeth per practice, and 1.6 teeth per patient. The cost of treating lesions that went undiagnosed and then progressed into more invasive restorations was estimated to be between $57M-$218M more (difference between NaF varnish and class II restorations), and $150M-$443M more (difference between Class II restoration and crown or crown with RCT). CONCLUSIONS: BWRs are crucial in diagnosing a significant number of carious lesions. There is considerable impact on health and cost to the national health system due to undiagnosed lesions. Practitioners need to be educated on reading and understanding BWR, and policy should be changed to cover BWR.

VALUE-BASED ORAL HEALTH CARE: IMPLEMENTATION LESSONS FROM FOUR CASE STUDIES.

Value-Based Healthcare has gained considerable attention in medicine but relatively little in oral health care so far. Implementation of Value-Based Oral Health Care (VBOHC) is complicated by a multitude of system-level and contextual factors, especially the siloed innovation culture in dentistry which has been evolving separately from the broader medical system. Previous literature has described 4 key limitations to adaptation of value-based health care, that is creating multidisciplinary units, measuring patient-centered outcomes, attributing and communicating costs, and bundling payments. This paper presents 4 case studies on oral health care which provide relevant learnings about addressing challenges when seeking to implement VBOHC: (i) The Nurse Practitioner-Dental (NPD) Model outlines an approach for creating a multi-disciplinary center in monitoring chronic diseases improving healthcare outcomes; (ii) Treatment of Early Childhood Caries displays the utility of quality measures in value measurement and placing patients at the center of their care; (iii) ClearChoice Dental Implant Centers outlines how cost attribution leads to better management and creation of value centers; and (iv) Proposed Payment Model Changes in Oral Maxillofacial Surgery outlines a method to cover all episodic care of this otherwise expensive disease. Despite the challenges of implementing VBOHC, this paper provides insights into its feasibility and actionability.

Interprofessional value-based health care: Nurse practitioner-dentist model.

OBJECTIVES: The United States health system is challenged to improve patient and population health, enhance patients' experience of care, and reduce health care costs. Value-based health care (VBHC) models are proposed to address these issues. Medical health systems are making strides toward VBHC, whereas dental care systems lag behind. The aims of this paper are to a) present study findings of an interprofessional practice model integrating oral health and primary care in a dental practice setting, and b) discuss practice and research implications for advancing VBHC approaches in oral health. METHODS: A nonexperimental research method was employed to evaluate the Nurse Practitioner-Dentist Model for Primary Care (NPD Model) at the Harvard Dental Center. Pretest/post-test design was used to assess clinical patient outcomes for a convenience cohort of Medicare beneficiaries (n = 31) with a reported diagnosis of hypertension and/or type 2 diabetes. Clinical outcome measures included: blood pressure, weight, body mass index (BMI), and Hemoglobin A1c. RESULTS: Positive and significant improvements in biometrics (blood pressure, body weight, BMI, HbA1c) were found. CONCLUSIONS: The NPD Model is an early prototype for interprofessional VBHC in oral health and holds promise for improving patient and population health outcomes. Integration of interprofessional VBHC in oral health is an imperative for achieving the Triple Aim to improve the overall health of our nation.
