Does Restriction of Public Health Care Dental Benefits Affect the Volume, Severity, or Cost of Dental-Related Hospital Visits?

PURPOSE: On July 1, 2012, the Illinois legislature passed the Save Medicaid Access and Resources Together (SMART) Act, which restricts adult public dental insurance coverage to emergency-only treatment. The purpose of this study was to measure the effect of this restriction on the volume, severity, and treatment costs of odontogenic infections in an urban hospital. MATERIALS AND METHODS: A retrospective cohort study of patients presenting for odontogenic pain or infection at the University of Illinois Hospital was performed. Data were collected using related International Classification of Diseases, Ninth Revision codes from January 1, 2011 through December 31, 2013 and divided into 2 cohorts over consecutive 18-month periods. Outcome variables included age, gender, insurance status, oral and maxillofacial surgery (OMS) consultation, imaging, treatment, treatment location, number of hospital admission days, and inpatient care level. Severity was determined by the presence of OMS consultation, incision and drainage, hospital admission, and cost per encounter. Hospital charges were used to compare the cost of care between cohorts. Between-patients statistics were used to compare risk factors and outcomes between cohorts. RESULTS: Of 5,192 encounters identified, 1,405 met the inclusion criteria. There were no significant differences between cohorts for age (P = .28) or gender (P = .43). After passage of the SMART Act, emergency department visits increased 48%, surgical intervention increased 100%, and hospital admission days increased 128%. Patients were more likely to have an OMS consult (odds ratio [OR] = 1.42; 95% confidence interval [CI], 1.11-1.81), an incision and drainage (OR = 1.48; 95% CI, 1.13-1.94), and a longer hospital admission (P = .04). The average cost per encounter increased by 20% and the total cost of care increased by $1.6 million. CONCLUSION: After limitation of dental benefits, there was an increase in the volume and severity of odontogenic infections. In addition, there was an escalated health care cost. The negative public health effects and increased economic impact of eliminating basic dental care show the importance of affordable and accessible preventative oral health care.

Oral and Maxillofacial Surgery Foundation Research and Fellowship Awards: A 26-Year Review at Massachusetts General Hospital and Harvard School of Dental Medicine.

PURPOSE: The purpose of this study was to review outcomes of the Oral and Maxillofacial Surgery (OMS) Foundation's funding awards to members of the OMS department at Massachusetts General Hospital (MGH) in terms of projects completed, abstracts presented, peer-reviewed publications, and career trajectories of recipients. MATERIALS AND METHODS: Data were collected from MGH and OMS Foundation records and interviews with award recipients. Primary outcome variables included 1) number of awards and award types, 2) funding amount, 3) project completion, 4) number of presented abstracts, 5) conversion from abstracts to publications, 6) number of peer-reviewed publications, 7) career trajectories of awardees, and 8) additional extramural funding. RESULTS: Eleven Student Research Training Awards provided $135,000 for 39 projects conducted by 37 students. Of these, 34 (87.2%) were completed. There were 30 student abstracts presented, 21 peer-reviewed publications, and a publication conversion rate of 58.8%. Faculty research awards comprised $1,510,970 for 22 research projects by 12 faculty members and two research fellows. Of the 22 funded projects, 21 (95.5%) were completed. There were 110 faculty and research fellow abstracts presented and 113 peer-reviewed publications, for a publication conversion rate of 93.8%. In the student group, 17 of 37 (45.9%) are enrolled in or are applying for OMS residencies. Of the 10 students who have completed OMS training, 3 (30%) are in full-time academic positions. Of the 12 faculty recipients, 9 (75%) remain in OMS academic practice. During this time period, the department received $9.9 million of extramural foundation or National Institutes of Health funding directly or indirectly related to the OMS Foundation grants. CONCLUSIONS: The results of this study indicate that 90.2% of projects funded by the OMS Foundation have been completed. Most projects resulted in abstracts and publications in peer-reviewed journals. These grants encouraged students to pursue OMS careers and aided OMS faculty in developing their research programs.

An audit into the reasons why treatment was not completed as planned under intravenous sedation in an adult oral surgery department, and the cost implications.

This audit aimed to identify the prevalence of, and reasons for failed intravenous conscious sedation in an adult oral surgery department, to develop recommendations to reduce such failures and to identify any cost implications. Data were collected prospectively for three months for all intravenous sedation appointments in the Oral Surgery department. Data were collected for 109 sedation appointments of which 83 were successful (76%). The failure rate (24%) was higher than the acceptable departmental failure rate (10%), and included reasons for failure that should have been avoided by a thorough patient assessment prior to treatment. Of the 26 failures, the most common reasons for failure were: cancellation: 8 patients (30.8%), failure to attend: 6 patients (23.1%), excessively late arrival of patient: 4 patients (15.4%) and failure to cannulate: 3 patients (11.6%). When sedation was unsuccessful, 13 of the 26 patients (50%) had their treatment successfully completed under local anaesthesia alone, 10 patients (38%) were rebooked for sedation and 3 patient. (12%) were rebooked for a general anaesthetic. Identifying and correcting the reasons for failure can result in vast savings in appointment time, clinical resources and cost. That 13 patients subsequently had their treatment completed under local anaesthesia alone opens the debate on how rigorous the patient assessment and allocation of sedation appointments was, and the potential to achieve savings.

The relative patient costs and availability of dental services, materials and equipment in public oral care facilities in Tanzania.

BACKGROUND: Patient charges and availability of dental services influence utilization of dental services. There is little available information on the cost of dental services and availability of materials and equipment in public dental facilities in Africa. This study aimed to determine the relative cost and availability of dental services, materials and equipment in public oral care facilities in Tanzania. The local factors affecting availability were also studied. METHODS: A survey of all district and regional dental clinics in selected regions was conducted in 2014. A total of 28/30 facilities participated in the study. A structured interview was undertaken amongst practitioners and clinic managers within the facilities. Daily resources for consumption (DRC) were used for estimation of patients' relative cost. DRC are the quantified average financial resources required for an adult Tanzanian's overall consumption per day. RESULTS: Tooth extractions were found to cost four times the DRC whereas restorations were 9-10 times the DRC. Studied facilities provided tooth extractions (100%), scaling (86%), fillings (79%), root canal treatment (46%) and fabrication of removable partial dentures (32%). The ratio of tooth fillings to extractions in the facilities was 1:16. Less than 50% of the facilities had any of the investigated dental materials consistently available throughout the year, and just three facilities had all the investigated equipment functional and in use. CONCLUSIONS: Dental materials and equipment availability, skills of the practitioners and the cost of services all play major roles in provision and utilization of comprehensive oral care. These factors are likely to be interlinked and should be taken into consideration when studying any of the factors individually.

Time and cost analysis: pediatric dental rehabilitation with general anesthesia in the office and the hospital settings.

Pediatric dental patients who cannot receive dental care in the clinic due to uncooperative behavior are often referred to receive dental care under general anesthesia (GA). At Stony Brook Medicine, dental patients requiring treatment with GA receive dental care in our outpatient facility at the Stony Brook School of Dental Medicine (SDM) or in the Stony Brook University Hospital ambulatory setting (SBUH). This study investigates the time and cost for ambulatory American Society of Anesthesiologists (ASA) Class I pediatric patients receiving full-mouth dental rehabilitation using GA in these 2 locations, along with a descriptive analysis of the patients and dental services provided. In this institutional review board-approved cross-sectional retrospective study, ICD-9 codes for dental caries (521.00) were used to collect patient records between July 2009 and May 2011. Participants were limited to ASA I patients aged 36-60 months. Complete records from 96 patients were reviewed. There were significant differences in cost, total anesthesia time, and recovery room time (P < .001). The average total time (anesthesia end time minus anesthesia start time) to treat a child at SBUH under GA was 222 ± 62.7 minutes, and recovery time (time of discharge minus anesthesia end time) was 157 ± 97.2 minutes; the average total cost was $7,303. At the SDM, the average total time was 175 ± 36.8 minutes, and recovery time was 25 ± 12.7 minutes; the average total cost was $414. After controlling for anesthesia time and procedures, we found that SBUH cost 13.2 times more than SDM. This study provides evidence that ASA I pediatric patients can receive full-mouth dental rehabilitation utilizing GA under the direction of dentist anesthesiologists in an office-based dental setting more quickly and at a lower cost. This is very promising for patients with the least access to care, including patients with special needs and lack of insurance.

Characteristics of dental clinics in US children's hospitals.

PURPOSE: This study's purpose was to describe the workforce, patient, and service characteristics of dental clinics affiliated with US children's hospitals belonging to the National Association of Children's Hospital and Related Institutions (NACHRI). METHODS: A 2-stage survey mechanism using ad hoc questionnaires sought responses from hospital administrators and dental clinic administrators. Questionnaires asked about: (1) clinic purpose; (2) workforce; (3) patient population; (4) dental services provided; (5) community professional relations; and (5) relationships with medical services. RESULTS: Of the 222 NACHRI-affiliated hospitals, 87 reported comprehensive dental clinics (CDCs) and 64 (74%) of CDCs provided data. Provision of tertiary medical services was significantly related to presence of a CDC. Most CDCs were clustered east of the Mississippi River. Size, workload, and patient characteristics were variable across CDCs. Most were not profitable. Medical diagnosis was the primary criterion for eligibility, with all but 1 clinic treating special needs children. Most clinics (74%) had dental residencies. Over 75% reported providing dental care prior to major medical care (cardiac, oncology, transplantation), but follow-up care was variable. CONCLUSIONS: Many children's hospitals reported comprehensive dental clinics, but the characteristics were highly variable, suggesting this element of the pediatric oral health care safety net may be fragile.

Doctor, my tooth hurts: the costs of incomplete dental care in the emergency room.

OBJECTIVES: This study aims to examine the charges and frequency of return visits for treating dental health problems in hospital emergency rooms (ERs) in order to provide a basis for policy discussion concerning cost-effective and appropriate treatment for those without access to private dental services. METHODS: Records were abstracted from hospital administrative data systems for dental-related ER visits from five major hospital systems in the Minneapolis-St. Paul metropolitan area during a 1-year period. Data on the number of visits and charges were analyzed by age and type of payor (public or private). Similar data were obtained from records for a commercially insured population from a single large employer. RESULTS: There were over 10,000 visits to ERs for dental-related problems with total charges reaching nearly $5 million in 1 year, mainly charged to public programs and reimbursed at about 50 percent. The frequency of repeat visits suggests that while acute pain and infection were treated by the ER physicians, the underlying dental problem often was not resolved. In contrast, a population with commercial dental insurance rarely used hospital ERs for dental problems. CONCLUSIONS: Access to preventive and restorative dental care is a critical public health problem in the United States, particularly for those without insurance and those covered by public programs. Public health policy initiatives such as the use of dental therapists should be expanded to improve access and to provide alternatives that offer more complete and less costly care for oral health problems than do hospital ERs.

Retrospective audit of Taranaki children undergoing dental care under general anaesthetic from 2001 to 2005.

A retrospective audit of trends in day-stay treatment for dental caries at a New Zealand hospital dental unit showed that demand for treatment has risen. The annual number of children undergoing a GA increased by over 13%, although the average waiting time after the initial consultation decreased. The cost of treatment also dramatically increased with time, as the numbers and complexity of cases increased. The type of treatment under GA changed over the five years, with more extractions occurring over the course of the audit. Restorations were still the most common treatment item provided, although the use of SSC trebled in 2004 and 2005. Socio-economic status, sex and ethnic differences were observed, with more boys and Maori receiving GA care and having a higher number of extractions. These children were identified as being high users of other hospital services (such as the Emergency Department).

Estimating unit costs for dental service delivery in institutional and community-based settings in southern Thailand.

In this cross-sectional study, the cost of different dental services was estimated and the unit costs of dental services for schoolchildren were compared between 2 settings: hospital-based and community-based mobile dental clinics. Heads of all departments in a selected community hospital were invited to attend 2 workshops to collect relevant data. Unit costs of different dental services varied from 41 to 2693 baht, with services falling into 4 unit cost groups: very high, high, moderate, and low. The very-high-unit-cost services included rehabilitative dental services. The high-unit-cost services covered removal of an impacted tooth, root canal treatment, and tooth-color fillings. The moderate-unit-cost group included a wide range of other dental services, with screening and oral hygiene instruction in community-based dental clinics falling into the low-unit-cost group. Generally, services provided in the community-based mobile clinic had lower unit costs than the same services provided in the hospital dental clinic.

Changes and factors associated with dentists' willingness to treat patients with severe disabilities.

OBJECTIVE: This study investigated changes in dentists' willingness to treat severely disabled patients and to understand dentists' opinions on reimbursements after the implementation of a dental care financial reward program in Taiwan. METHODS: Three hundred dentists from 29 teaching hospitals were randomly selected to answer a structured questionnaire, and 184 structured questionnaires were returned. Multiple regression analysis was used to examine the factors associated with dentists' willingness to treat severely disabled patients. RESULTS: Approximately 60% of the dentists said reimbursements for treatment of severely disabled patients were reasonable. 50.4% of dentists were willing or very willing to treat disabled patients. Seventy-nine percent dentists affected by the program had a higher willingness but 83.7% dentists said this program did not make a significant difference to their income. 52.8% of dentists agreed the program would increase the quality of dental care. The factors significantly affecting dentists' willingness included dentist's age, specialty field, perception of the program in promoting the quality of dental services, and perception of the ability to provide adequate treatments for severely disabled patients. CONCLUSIONS: The rewards program significantly increased the willingness of most hospital-base dentists to treat the severely disabled patients although the effect of incentive to their income was limited.

Measuring the cost, effectiveness, and cost-effectiveness of orthodontic care.

AIM: To determine the relative effectiveness and cost-effectiveness of orthodontic treatment per case in one "fee for item" and two different types of salaried orthodontic clinics. SUBJECTS AND METHODS: This prospective study recruited a random sample of six self-employed orthodontists (fee-for-item) and six orthodontists from both hospital and community clinics (salaried services). One hundred patients were followed to completion of orthodontic care. Questionnaires were employed to determine cost of treatment from the clinicians' and patients' points of views. Four cost-effectiveness models were developed. RESULTS: Complete records of outcome were available for 1,087 patients, but only 789 had complete data on costing. Three of the four cost-effectiveness models indicated similar rankings for the 18 clinicians. The most cost-effective service was provided by clinicians working in community clinics, followed by clinicians working in hospitals, then self-employed clinicians. The preferred cost-effective model takes into consideration the initial need and successful outcome of orthodontic treatment. CONCLUSION: Cost-effectiveness models have been developed to quantify the performance of individual clinicians working in self-employed and salaried clinics. Costs and effectiveness of the clinicians in each clinical setting show considerable variation.

A cost and production analysis of hospital dental care programs.

To provide hospital dental programs with useful information about the expansion of dental services and the identification of pertinent financial information, a production function and cost function analysis was performed. Results showed that hospital ownership (public or private) and size of the dental clinics were associated with the cost of providing dental services and the volume of services provided. Among 23 hospitals studied, private hospitals had a much lower cost per visit, had more paid attending dentist staff, paid their resident dentists less, and had significantly more billings paid by Medicaid and by patients than public hospitals. When stratified by ownership and size, these basic differences were accentuated for the small clinics. Except for primarily the Medicaid and self-pay billings, the characteristics of large public and private hospital dental clinics were extremely similar. Multiple regression analysis found that a decrease in cost per visit was associated with more visits to dentists and more to hygienists. Production of dental services could be increased by increasing the number of attending dentists, hygienists, and residents. Preliminary econometric analysis reveals that the optimal mix of attending dentists to resident dentists should be approximately 1.8 full-time equivalent (FTE) resident for every 1 attending FTE dentist to produce the most dental services at the lowest cost.

A retrospective analysis of the costs associated with the treatment of nursing caries in a remote Canadian aboriginal preschool population.

Nursing caries is a specific form of rampant dental caries affecting the majority of preschool aboriginal children who live in the Province of Manitoba, Canada. Since the majority of these individuals live in remote regions of the province access to dental treatment is difficult, resulting in long delays in the provision of treatment and, most likely, significant morbidity associated with dental pain and oral infection. Travel to distant centres for treatment under general anesthesia by pediatric dentists has become the usual method by which treatment is provided to the majority of affected children. We believed that this was an expensive method of providing these necessary services and our purpose was to document all costs associated with the treatment of nursing caries in this population. We analyzed the records of 884 children who were treated for nursing caries between 1980 and 1988 in Manitoba and collected data for costs in the following categories: travel, lodging, medical, dental, hospital and nursing. Our results show that the remote band groups had significantly higher costs (P < 0.001) than groups which were located closer to treatment centres. The costs which accounted primarily for this significant difference were travel and medical costs associated with hospitalization and the administration of general anesthesia. Our results support the need for the redeployment of resources on the basis of regional need and the development of community-based preventive programs and treatment programs which will significantly reduce the incidence of nursing caries in preschool Canadian aboriginal children.

Caries and the preschool child: treatment of the preschool child in the hospital service.

Dental treatment of the preschool child in hospital is usually carried out under a general anaesthetic, following referral from a dentist. The reasons for a general anaesthetic are that the child has either proved unable to accept treatment because of dental anxiety or extreme youth or has a severe medical problem which requires dental care to be carried out in a hospital environment. The costs of such treatment are necessarily high and account of these is taken in the description of the services offered and their organization. The need for prevention is also stressed.

The effects of the Women, Infants, and Children's Supplemental Food Program on dentally related Medicaid expenditures.

OBJECTIVE: This study estimates the effects of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on dentally related Medicaid expenditures for young children. METHODS: We used a five-year cohort study design to compare dentally related Medicaid expenditures for children enrolled in WIC versus those not enrolled for each year of life up to age 5 years. There were 49,795 children born in North Carolina in 1992 who met the inclusion criteria for the study. Their birth records were linked to Medicaid enrollment and claims files, WIC master files, and the Area Resource File. Our analysis strategy included a logit and OLS two-part model with CPI dollar adjustments. RESULTS: Children who participated in WIC at ages 1 and 2 years had significantly less dentally related expenditures than those who did not participate. WIC participation at age 3 years did not have a significant effect. Fewer WIC children received dental care under general anesthesia than non-WIC children. CONCLUSIONS: The WIC program has the potential for decreasing dentally related costs to the Medicaid program, while increasing use of dental services.

Comparison of access and costs of Medicaid dental services in a hospital clinic and community practices.

OBJECTIVES: This paper reports the results of a three-year evaluation of access to dental care and its associated costs for Aid to Families with Dependent Children (AFDC) beneficiaries enrolled in a hospital-based health maintenance organization (HMO) or a fee-for-service (FFS) option. METHODS: Medicaid enrollees (n = 3, l655) having a year of eligibility were assigned to either the hospital HMO or FFS care, and their use of dental care and its costs compared. RESULTS: A higher percent of those beneficiaries enrolled in the FFS option used dental care than those in the HMO plan. FFS enrollees also had more annual visits per person than those in the randomly assigned HMO group. FFS dental patients treated in the hospital had the highest costs of any payment-provider combination studied. CONCLUSIONS: To understand the mix of utilization rates, visits, and costs, one must take into account the way in which the HMO hospital plan is reimbursed, the way in which the dental department is reimbursed, and the way in which the dental provider is reimbursed.

Medicaid costs associated with the hospitalization of young children for restorative dental treatment under general anesthesia.

OBJECTIVE: This paper examines the cost to the Iowa Medicaid program of hospitalizing young children for restorative dental care under general anesthesia, and describes the dental services received in this setting. METHODS: Medicaid dental claims for young children receiving restorative dental care under general anesthesia during fiscal year 1994 were matched with corresponding hospital and anesthesia claims. RESULTS: The total cost to the Medicaid program of treating a child in the hospital under general anesthesia was $2,009 per case. Less than 2 percent of Medicaid-enrolled children under 6 years of age who received any dental service accounted for 25 percent of all dollars spent on dental services for this age group, including hospital and anesthesia care. The most frequent type of procedure was stainless steel crowns (SSCs), with an average of almost six per case. CONCLUSIONS: Early identification, prevention, and intervention are critically important to prevent the costly treatment of children with ECC in hospital operating rooms.

Dental services, costs, and factors associated with hospitalization for Medicaid-eligible children, Louisiana 1996-97.

OBJECTIVE: This study compared types and costs of dental services rendered to children who had received care in a hospital operating room (H) with children who had not (NH). METHODS: The study population consisted of all children aged 1-5 years who received a dental service reimbursed by the Louisiana Medicaid EPSDT program from October 1996 through September 1997. Claim files were provided by the Louisiana Bureau of Health Services Financing. A treatment intensity index [TII = 3 x (# extractions) + 2 x (# pulpotomies + # crowns) + # simple restorations] was calculated for H children (n = 2, 142) and NH children (n = 38,423). Using logistic regression, a dichotomous hospitalization variable (H vs NH) was regressed against treatment intensity and selected personal and parish (county) characteristics for each of the five age groups. Total and average reimbursement per child were calculated for both groups of children, by age. RESULTS: The mean treatment intensity scores for H and NH children were 24.02 (SD = 11.82) and 2.16 (SD = 4.78), respectively. For all age groups, children with treatment intensity scores greater than 8 were at least 132 times more likely to be hospitalized than were children with scores less than or equal to 8. The mean cost for care provided to H children was $1,508 compared with $104 for NH. Total costs for dental care rendered to H children (5% of the study population) were $3,229,851 (45% of total dental costs for the study population). CONCLUSION: Reducing severe caries through early interventions could provide substantial cost savings.
