Health services research.

The major barriers to the collection of primary population-based dental services data are: (1) Dentists do not use standard record systems; (2) few dentists use electronic records; and (3) it is costly to abstract paper dental records. The value of secondary data from paid insurance claims is limited, because dentists code only services delivered and not diagnoses, and it is difficult to obtain and merge claims from multiple insurance carriers. In a national demonstration project on the impact of community-based dental education programs on the care provided to underserved populations, we have developed a simplified dental visit encounter system. Senior students and residents from 15 dental schools (approximately 200 to 300 community delivery sites) will use computers or scannable paper forms to collect basic patient demographic and service data on several hundred thousand patient visits. Within the next 10 years, more dentists will use electronic records. To be of value to researchers, these data need to be collected according to a standardized record format and to be available regionally from public or private insurers.

Loss of work productivity due to illness and medical treatment.

We examined the effects on work productivity of treatment with antihistamines in a retrospective study using linked health claims data and daily work output records for a sample of nearly 6000 claims processors at a large insurance company, between 1993 and 1995. We explained the variation in work output depending on the subjects' demographic characteristics, their jobs, and whether they were treated with "sedating" versus "nonsedating" antihistamines for nasal allergies. Differences of up to 13% in productivity were found after the subjects took sedating or nonsedating antihistamines. The observed effect suggests substantial indirect economic costs, which up to now have been largely overlooked because work productivity has proved difficult to measure objectively.

Utilization management as a cost-containment strategy.

Utilization management (UM) is now an integral part of most public and private health plans. Hospital review, until recently the primary focus of UM, is associated with a reduction in bed days and rate of hospital cost increases. These reductions appear to have had limited impact on aggregate health care costs because of increases in unmanaged services. In the future, with electronic connectivity between payers and providers and the use of clinical guidelines and computer-based decision-support systems, the need for prospective case-level reviews will be reduced. With these changes, UM programs are likely to become more acceptable to providers and patients.

A principal components analysis of human odontometrics.

It has long been recognized that tooth crown diameters in hominoids are all positively intercorrelated one with another. This study reports on sex-specific correlation matrices derived from 2,650 individuals from the Solomon Islands, Melanesia. Mesiodistal and buccolingual diameters of all permanent teeth from one side are used, excluding third molars. Analysis discloses significant sex dimorphism in the strengths of the intercorrelations, with females being better integrated. Principal components analysis (PCA) provides an objective means of data reduction (shown here to be preferable to simple size summation methods) and decorrelation of the resulting linear combinations. Four components are extracted (with results being virtually identical in the two sexes) and arguments are put forth that varimax rotation to "a simpler solution" may be counterproductive. Before rotation, the four components are 1) overall size, 2) buccolingual widths contrasted with mesiodistal lengths, 3) anterior (I,C) contrasted with posterior (P,M) teeth, and 4) premolars contrasted with molars. Most of the explained (shared) variance (63%) extracted by PCA is in overall size of the dentition. There is a strong urge to view the results of these principal components analyses as reflective of biologically and genetically meaningful entities.

Changing patterns of oral health and implications for oral health manpower. Responsibility to the public.

This paper examines organized dentistry's responsibility for informing the public about changing patterns of oral disease. The public is divided into two groups: governments and other organizations that are responsible for allocating funds for dental treatment, education and research, and the general population that is eligible to use dental services. Some governments in industrialized countries apparently believe that with the decline in caries, monies for dentistry can be reduced without affecting the oral health of the population. This assumption can be challenged, since oral disease levels in lower socioeconomic class groups and the elderly continue to be very high. Further, the goals of the dental care system should be raised to eliminate edentulousness. Dentistry needs to make the public aware that adequate care for the poor and elderly and eliminating edentulousness will require increased support for dentistry. At the patient level, regular users of care who are healthy should be informed that more frequent visits and complex services may have little effect on oral health. In contrast, infrequent users of dental care should be made aware that dentistry has the technology to prevent disease and the loss of teeth. One phase in the history of dentistry is coming to an end but another is beginning. In the new era the dental profession can make even greater contributions to the quality of life of individuals and society.

Dental insurance and the oral health of preschool children.

Using data from the Rand Health Insurance Experiment, the effects of cost-sharing plans on the health of the primary teeth in 264 children aged 3 to 5 years were investigated. From six areas in the United States, families were assigned at random to different dental and medical insurance plans. The plans varied in the amount of required cost sharing. Families participated in the study for 3 (70%) or 5 (30%) years. Children covered by the plan (requiring no cost sharing) had significantly fewer decayed teeth and deft (decayed, extracted, and filled teeth) at the end of the study than did children covered by the cost-sharing plans. No differences existed among plans in the number of extracted and restored teeth. Children of middle- and low-income families benefited most from having access to free dental care.

The demand for dental care: evidence from a randomized trial in health insurance.

Using data from a randomized trial in health insurance, this paper examines the effect of cost sharing on use of dental services. The data come from a sample of the nonaged, noninstitutionalized civilian population of six urban and rural sites. We find that: reducing the level of cost sharing increases demand for dental services; and dental expenses rise 46% when the coinsurance rate falls from 95% to 0%, subject to a catastrophic limit on out-of-pocket expenses. Of this increase, two-thirds is attributable to an increase in the likelihood of visiting a dentist during the year. Moreover, there is a substantial surge in demand during the first year of more generous coverage. The first-year response to cost sharing is nearly twice the second-year response.

Quality assurance and development of criteria and standards.

This article considers some fundamental considerations in developing criteria and standards for use in a formal quality assurance program. These include the purpose of the review system, the types of problems being addressed, the availability of data, and the time and money that can be devoted to improving clinical performance.

Identification of practice problems in dentistry.

This paper examines the use of dental insurance claim data for studying the dental care delivery system. Several research projects are described including investigations of the amount, types and causes of variation in dental practice patterns, the cost-effectiveness of different patterns of care in producing oral health, the feasibility of focused utilization review systems and the selection of continuing education topics and participants. The importance of these and other data information systems to the future practice of dentistry and medicine is stressed.
