Patient-related predictors of rehabilitation use for community-dwelling older Americans.

OBJECTIVE: To determine patient factors that predict use of physical or occupational therapy (PT/OT) services by elderly people. DESIGN: Time-series study of the relationship of PT/OT use to a variety of characteristics present at baseline. PARTICIPANTS: Eight-hundred nine community-dwelling men and women aged 65 and older. SETTING: The Medicare Screening and Health Promotion Trial at UCLA. MAIN OUTCOME MEASURES: Use of PT/OT services, as reported in a telephone survey 1 year after initial information was obtained on the same subjects by the baseline telephonic survey. RESULTS: Fifteen percent of the sample used PT/OT within 12 months of baseline. In multiple logistic regression analysis, PT/OT use was significantly less frequent among racial minorities, less well educated groups, and the oldest age group. PT/OT use was higher among those who had both functional disability and the presence of arthritis, heart or lung disease, or a prior history of stroke. However, neither functional disability alone nor the presence of arthritis, cardiovascular or lung disease, in the absence of limited functioning, was associated with PT/OT use. Patients who had obtained a pneumococcal vaccination or used transportation services were also more likely to receive PT/OT. CONCLUSIONS: Our findings suggest that there may be important sociodemographic inequalities in the use of rehabilitation services and raise the possibility of inappropriate underuse in certain subgroups. Additional studies are needed to determine whether similar inequalities of PT/OT use are found in other populations and whether rehabilitation is effective in various subgroups.

Measurement of dollar value of services in a capitated dental plan.

A number of attempts have been made to develop measures of the cost of resources expended to produce specific services that are more equitable than fees. Two conceptually different relative value methods (RVU and RTCU) and UCR fee-for-service were used to measure the dollar value of care produced in three consecutive years under a network-type capitation dental plan. While each yielded a different total, the values were relatively close in the first year. However, they diverged in the second and third years even when an inflation factor was kept constant for all three. In addition, the dollar value of specific services varied markedly over the three methods. The relative merits of the different systems are discussed, as well as possible reasons for the divergence. It is concluded that the RTCU system is preferable, but that great care must be taken to keep any system current, regardless of specific derivation.

Contribution of pretreatment radiographs to orthodontists' decision making.

A study was conducted to determine the amount of diagnostic and treatment planning information gained by orthodontists when pretreatment radiographs are added to a set of orthodontic records. Thirty-nine orthodontists evaluated six test cases and formulated a diagnosis and treatment plan. Information was collected about the participants' certainty with their diagnoses and treatment plans, the impact of the radiographs, the number and type of radiographs that were selected, and the difficulty of each case. Results showed that orthodontists were approximately 75% confident of their diagnosis before reviewing any radiograph. There were 741 radiographs ordered, of which 192 produced changes to the diagnostic process. The lateral cephalometric radiograph was the most productive. Panoramic and full-mouth series were productive but provided largely duplicative information.

A comparison of quality in a dual-choice dental plan: capitation versus fee-for-service.

The quality of dental care provided under a dual-choice dental plan was evaluated. Eleven practices, six capitation and five fee-for-service, were examined. The methodology was based primarily on examination of elements of structure and process of care. Samples of patient dental records were drawn from each practice for a total of 495 patient records. The results showed that none of the five fee-for-service dental practices and only two of the capitation practices were found to meet all the criteria for acceptable dental practice. Universally poor documentation made it extremely difficult to evaluate process measures of care. Fee-for-service patients received more visits and services than capitation patients. Overtreatment occurred in fee-for-service practices and undertreatment occurred in capitation practices. The distribution of services also differed, with capitation practices providing a less expensive type of service. Annual utilization of one or more services for capitation practices varied substantially by the practice. In this plan, both capitation and fee-for-service practices demonstrated a need for strong quality assurance mechanisms to protect the interests of patients.

Development of the Geriatric Oral Health Assessment Index.

The development of measures for assessing oral health status is essential to the evolution and maturation of a scientific knowledge base in geriatric dentistry. The literature suggests a high prevalence of dental diseases in older adults, yet valid and reliable instruments to assess the impact of oral diseases on older individuals or populations are lacking. This paper describes the rationale for and the development of the Geriatric Oral Health Assessment Index (GOHAI), a self-reported measure designed to assess the oral health problems of older adults. Following a review of the literature and consultation with health care providers and patients, a pilot instrument was developed. The GOHAI was initially tested on a convenience sample of 87 older adults. A revised instrument was then administered to a sample of 1755 Medicare recipients in Los Angeles County. The GOHAI demonstrated a high level of internal consistency and reliability as measured by a Cronbach's alpha of 0.79. Associations of the GOHAI with a single-item rating of dental health and with clinical and sociodemographic supported the construct validity of the index. Having fewer teeth, wearing a removable denture and perceiving the need for dental treatment were significantly related to a worse (lower) GOHAI score. Respondents who were white, well educated, and with a higher annual household income were more likely to have a high GOHAI score, indicating fewer dental problems. Additional applications of the GOHAI are necessary to further evaluate the instrument's validity and reliability, and to establish population norms of oral health in older adult populations as measured by the GOHAI.

Have dentists assimilated information about AIDS?

A random sample of 396 general dentists, oral surgeons, and periodontists in Los Angeles was interviewed in fall 1986. The purpose was to determine their experience in treating patients infected with HIV, factors associated with their knowledge about signs and symptoms of AIDS, and their sources of information regarding AIDS. The results showed that one-third of the dentists reported treating a known or suspected AIDS patient and that 56 percent indicated that they would not or could not treat patients with AIDS. Dentists displayed little knowledge of the oral and systemic signs and symptoms of AIDS. They reported professional journals, continuing education, and the popular press as the sources of information regarding AIDS that they found most useful. Yet those who reported attending continuing education were found to have only slightly greater knowledge of diagnostic signs. After two or more reported lectures on AIDS, 31 percent still named no oral signs and symptoms of AIDS.

Radiographic examinations of orthodontic educators and practitioners.

Orthodontic educators and practitioners were surveyed to determine the radiographs each prescribes to diagnose Class II malocclusion patients. Results of the study were based on 141 responses. The frequency of ordering each of ten radiographic projections and the importance of these radiographs to the orthodontists' diagnosis and treatment planning were measured. A lateral cephalometric and panoramic film were found to be the most frequently ordered and the most diagnostically important radiographs. Differences between the two groups were found regarding their use of supplementary radiographs. Educators were found to order more radiographs for their patients.

Comparisons between dentist ratings and self-ratings of dental appearance in an elderly population.

Little is known about dental appearance in terms of the elderly population. The purpose of this paper is to compare self-reported dental appearance with dentist-rated appearance for individuals over 65. The subjects (N = 550) were participants in the Los Angeles based Medicare Screening and Health Promotion Trial. Most were female (57.3%), white (89.0%), and married (62.0%), with a mean age of 74.5 years. About one-third had incomes greater than $25,000. Results are based on a 45 minute telephone interview and onsite dental screening. Findings show that 40% of the self-ratings on a five point scale were higher than the dentist ratings, and 22% were lower. Bivariate analyses showed that both sets of ratings were related to dental status variables, self-reported health, and education. High self-ratings were also associated with being white and having a positive mental health status, while high dentist ratings were associated with patients who were younger, married, and who had higher income and social network scores. Comparison of results from two multiple regressions showed unique predictors for the self-ratings (marital status and GOHAI scores) and for the dentist ratings (sex and income). These discrepancies can raise barriers to effective treatment planning in the elderly, which could affect utilization and satisfaction.

An association between dentate status and hearing acuity.

Hearing improvement following dental treatment has been reported in case studies, yet few objective studies of this phenomenon have been conducted. To determine if a relationship exists between dentate status and hearing acuity, we conducted a retrospective study of elderly subjects enrolled in a health promotion clinical trial. Air-conduction pure tone average thresholds (PTA) administered to left and right ears at 500 Hz, 1000 Hz, 2000 Hz, 3000 Hz, 4000 Hz, and 6000 Hz were used to create six hearing outcome variables, and were compared between groups of subjects who either had 25 or more teeth (n = 182) or were edentulous (n = 43). Mean PTA thresholds were significantly greater (p < 0.05) in edentulous subjects for each hearing outcome variable, and differences between unadjusted group means ranged from 4.9 dB to 8.6 dB. Mean PTA thresholds adjusted for clinical factors known to affect hearing also indicated worse hearing acuity in the edentulous group. These pilot findings suggest an association between dentate status and hearing acuity.

Enrolling community physicians and their patients in a study of prevention in the elderly.

Enrollment of senior citizens in a community Medicare demonstration project to explore the efficacy of preventive health screening and health education was accomplished by using a two-stage process. This process consisted of initial communication with community physicians through the University of California at Los Angeles Clinical Faculty Association to establish credibility for the program. Physicians who agreed to participate then selected potential participants to receive, by mail, a description of the study and an introductory letter from their own physician. Followup and actual enrollment of participants was then handled by the study team. A total of 57.6 percent of the elderly people approached agreed to participate in the study.

Orthodontic radiographic usage by pediatric dentists.

Pediatric educators and practitioners were surveyed to determine the composition of the radiographic examination used to diagnose patient malocclusion; pediatric dentists provide the initial diagnosis for much of the orthodontic service provided to children and adolescents. The initial diagnosis of malocclusion is based on information obtained from a clinical and radiographic examination. Results of the study are based on the 111 pediatric dentists who report providing comprehensive orthodontic treatment. For those who reported providing comprehensive orthodontic therapy, the frequency of ordering each of ten radiographs and the importance of the radiographs to the dentists' diagnosis and treatment plans were measured. The bitewing, lateral cephalometric and panoramic radiographs were the most frequently ordered radiographs for both young and older patients. Radiographic and clinical examinations were judged to be of equal importance to more than fifty percent of the dentists.

Health promotion and disease prevention for older adults: opportunity for change or preaching to the converted?

Health promotion and disease prevention for the elderly offer the potential for improving the quality of life for the growing population of older adults, while reducing the economic burden on the health system. Whether this potential can be realized depends, in part, on whether those older adults whose health behaviors put them at risk actually use preventive services when offered the opportunity. In 1988 the Health Care Financing Administration began a series of health promotion demonstrations to address health issues related to older adults. This article reports on program participation at one of the five demonstration sites. Over 1,900 community-dwelling Medicare beneficiaries who receive their health care through fee-for-service providers were enrolled in the demonstration. These enrollees were randomly assigned to control and experimental groups, with the latter offered health screening and promotion services. Nine hundred-seventy-three of the experimental subjects and 938 of the control subjects completed a lengthy telephone interview, which determined each person's use of preventive services and practices. Although all 973 experimental subjects were invited by letter and follow-up telephone calls to attend these free-of-charge, Medicare-provided sessions, not everyone attended. We analyzed 17 health behaviors of those who attended the first session and those who did not. Those engaging in these preventive behaviors were neither more nor less likely to attend the screening services. Thus, we found neither "favorable" nor "unfavorable" selection bias in the use of these preventive services.

Mammography use in older women with regular physicians: what are the predictors?

Results of a longitudinal study of 1,050 women 65 years of age and older under the care of faculty internists demonstrate that individual and sociodemographic factors predict mammography use. The majority of the sample (79%) had received a mammogram within the past two years. Multiple logistic regression analyses of findings from a telephone survey showed that mammographic screening was significantly higher among women who had recently received a Pap smear, whose annual household incomes exceeded $30,000, and whose personal health care habits were preventively oriented; they used more preventive services such as routine dental care and engaged in more preventive behaviors such as seat-belt use and routine exercise. Mammography use was significantly higher among those 75 or younger. These findings suggest that enhancing patient preventive orientations should be part of interventions designed to increase screening.
