What influences physician practice behavior? An interview study of physicians who received consultative geriatric assessment recommendations.

BACKGROUND: Comprehensive geriatric assessment (CGA) in outpatient settings has not been shown to be as effective in reducing mortality and improving health as in hospital settings; this difference has been attributed in part to a lack of direct control over recommendation implementation. OBJECTIVE: To identify inhibiting and facilitating factors in physicians' compliance with consultative CGA recommendations, so that the effectiveness of outpatient CGA might be improved. METHODS: A 49-item questionnaire was administered via the telephone to 87 eligible community primary care physicians in Los Angeles, Calif, whose patients had received consultative outpatient CGAs as part of a study of CGA (response rate, 96%). The questionnaire assessed physician compliance with CGA recommendations, reasons for implementing or not implementing the recommendations, and specific physician attitudes, perceptions, and characteristics. The focus of the interview was the CGA recommendation that was determined to be the "most important" by the evaluating geriatrician. Recommendations addressed geriatric syndromes, general medical problems, or psychiatric conditions. RESULTS: Of the 87 physician respondents, 62 (71%) implemented the most important recommendation. In multivariate analysis, 4 variables were predictive of physician compliance: (1) a patient's request that the recommendation be implemented (odds ratio [OR], 10.8; 95% confidence interval [CI], 1.9-61.3; P = .007); (2) perceived legal liability resulting from nonimplementation of the recommendation (OR, 10.8; 95% CI, 1.1-108.2; P = .04); (3) female physician gender (OR, 9.6; 95% CI, 1.4-67.9; P = .04); and (4) perceived cost-effectiveness of the recommendation (OR, 7.0; 95% CI, 1.6-30.5; P = .01). CONCLUSIONS: Patient behavior, which may be modifiable, was among the strongest determinants of physician compliance with recommended care. Specifically, when patients requested that a recommendation be implemented, physicians were highly likely to comply. Changing patient behavior within the physician-patient relationship as a way of effecting desired changes in physician health care practices merits further attention.

Physician implementation of and patient adherence to recommendations from comprehensive geriatric assessment.

PURPOSE: The goals of this study were to develop and determine the feasibility of interventions designed to increase both primary care physician implementation of and patient adherence to recommendations from ambulatory-based consultative comprehensive geriatric assessment (CGA), and to identify sociodemographic and intervention-related predictors of physician and patient adherence. PATIENTS AND METHODS: One hundred thirty-nine community-dwelling older persons who failed a screen for functional impairment, depressive symptoms, falls, or urinary incontinence received outpatient CGA consultation. These patients and the 115 physicians who provided primary care for them received one of three adherence interventions, each of which had a physician education component and a patient education and empowerment component. Recommendations were classified as physician-initiated or self-care and as "major" or "minor"; one was deemed "most important". Adherence rates were determined on the basis of face-to-face interviews with patients. RESULTS: Based on 528 recommendations for 139 subjects, physician implementation of "most important" recommendations was 83% and of major recommendations was 78.5%. Patient adherence with physician-initiated "most important" and "major" recommendations were 81.8% and 78.8% respectively. In multivariate models, only the status of the recommendation of "most important" (odds ratio 2.4, 95% CI [confidence interval] 1.3 to 4.5) and health maintenance organization (HMO) status of the patient (odds ratio 2.1, 95% CI 1.3 to 3.6) remained significant in predicting physician implementation. The logistic model predicting patient adherence to physician-initiated recommendations included male patient gender (odds ratio 3.1, 95% CI 1.3 to 7.0), the status of the recommendation of "most important" (odds ratio 1.9, 95% CI 1.0 to 3.8), total number of recommendations (odds ratio 0.7, 95% CI 0.5 to 0.9), and total number of problems identified by CGA (odds ratio 1.8, 95% CI 1.2 to 2.7). CONCLUSIONS: These findings indicate that relatively modest interventions strategies are feasible and lead to high levels of physician implementation of and patient adherence to physician-initiated CGA recommendations. These interventions appear to be particularly effective in HMO patients and for recommendations that were deemed to be "most important".

"Lifestyle" interventions for promoting physical activity: a kilocalorie expenditure-based home feasibility study.

The Centers for Disease Control and Prevention and the American College of Sports Medicine in cooperation with the President's Council of Physical Fitness and Sports recommended short periods of daily kilocalorie (calorie) expenditure with moderate-intensity physical activities to complement the currently existing recommendations. In this study the feasibility (adherence and safety) of employing calorie expenditure as the basis for prescribing a home-based walking program to healthy, community-dwelling men and women was examined. This was a 16-week pretest-posttest feasibility study of a home-based calorie-expenditure walking program conducted in an outpatient clinic in an academic medical center. Participants included 20 healthy, elderly, community-dwelling men and women. A 16-week home-based walking program was individually prescribed as a weekly amount of calorie expenditure increasing from an initial 300 calories per week to 1,200 calories per week (approximately 30 minutes of walking daily) during the final 6 weeks of the study. Adherence to the program was recorded individually in a diary (kept daily and reviewed at each visit), body weight, and walking pace. All but one participant were able to complete this 16-week program (95 percent adherence). That a calorie-based approach to promote physical activity among the elderly has a high adherence rate is suggested by these findings. Additional studies are necessary to define the potential role for this approach in promoting physical activity and improving health outcomes among the elderly.

The Prevention for Elderly Persons (PEP) Program: a model of municipal and academic partnership to meet the needs of older persons for preventive services.

OBJECTIVE: To create a program to identify preventive needs for community-dwelling older persons and incorporate intervention strategies to improve implementation of these services. DESIGN: Program development and case-series. SETTING: Community-based meal sites, academically administered program. PARTICIPANTS: Persons 60 years of age or older attending meal sites and their primary care physicians. MEASUREMENTS: Demographic characteristics, self reported preventive health behaviors and services, blood pressure measurement. RESULTS: During the first 2 years of the program, 927 persons 60 years of age or older were screened. The most common physician-initiated preventive recommendations were: tetanus booster (72%), aspirin prophylaxis (68%), pneumonia vaccination (61%), and colorectal cancer screening (51%). The most common self-care recommendations have been: calcium supplementation (54% of women) and breast self examinations (51% of women). As part of the adherence intervention, we were able to complete health educator calls for 600 (65%) subjects. In addition, the physicians of 599 (65%) subjects were contacted either by telephone (n = 496) or by letter only (n = 97). CONCLUSION: A community based preventive services program can identify large numbers of unmet preventive services needs, and a dual intervention strategy aimed at meeting these needs can be delivered successfully to the majority of participants. Implementation rates of specific recommendations and impacts on health outcomes remain to be determined.

Looking inside the black box of comprehensive geriatric assessment: a classification system for problems, recommendations, and implementation strategies.

OBJECTIVE: To develop and test the inter-rater reliability of a coding system for geriatric problems identified through Comprehensive Geriatric Assessment (CGA) of hospitalized older persons, recommendations generated by the assessment, and implementation strategies for these recommendations. DESIGN: Validation study. SETTING: A health maintenance organization and a geriatrics academic program. PARTICIPANTS: A total of 49 hospitalized older persons, who met at least 1 of 13 inclusionary "targeting" criteria, two geriatricians, and one social worker who coded forms. MEASUREMENTS: Standardized coding of CGA consultation sheets into (1) geriatric problems identified, (2) recommendations, and (3) implementation strategies; inter-rater reliability testing of coding system using two physicians and a social worker. RESULTS: On average, each assessed patient had 4.8 recommendations. The largest percentages of recommendations were for non-physician referrals (18.2%), advance directives (13.4%), medication adjustments (11.5%), diagnostic evaluation/monitoring (11.5%), and community services (10.9%). The proportions of agreement between raters in coding problems ranged from 0.77 to 0.90, in coding recommendations from 0.69 to 0.86, and in coding implementation strategies from 0.68 to 0.83. CONCLUSION: A classification system for measuring some components of the process of care of CGA has satisfactory inter-rater reliability, can be adapted for other settings, and may provide valuable insight into determining which components of CGA confer health benefits.

Driving and dementia California's approach to a medical and policy dilemma.

The cognitive impairment that defines dementia is thought to place affected persons at increased risk for unsafe driving. Nevertheless, many persons with dementia continue to drive after the onset of their illness. Since 1988 California physicians have been required to report older persons with Alzheimer's disease and related disorders to their local health departments, information that is then reported to the Department of Motor Vehicles (DMV). To reevaluate how it acts on this information, the DMV convened an interdisciplinary panel of experts and modified its policies regarding drivers with dementia. As revised, the driver's licenses of persons with moderate or advanced dementia will be revoked without further testing. Persons with early or mild dementia will have the opportunity to demonstrate the capacity to drive through a reexamination process. In this manner, the California DMV hopes to balance the need for public safety and with the preservation of personal independence of persons with dementia.

A randomized trial of comprehensive geriatric assessment in the care of hospitalized patients.

BACKGROUND: Although many studies describe benefits from the comprehensive assessment of elderly patients by an interdisciplinary team (comprehensive geriatric assessment), the most supportive evidence for the process has come from programs that rely on specialized inpatient units and long hospital stays. We examined whether an inpatient geriatric consultation service might also be beneficial in a trial involving four medical centers of a group-practice health maintenance organization (HMO). METHODS: We conducted a randomized clinical trial with 2353 hospitalized patients 65 years of age or older in whom at least 1 of 13 screening criteria were present: stroke, immobility, impairment in any basic activity of daily living, malnutrition, incontinence, confusion or dementia, prolonged bed rest, recent falls, depression, social or family problems, an unplanned readmission to the hospital within three months of a previous hospital stay, a new fracture, and age of 80 years or older. Of the 1337 patients assigned to the experimental group, 1261 (94 percent) received a comprehensive geriatric assessment in the form of a consultation, with limited follow-up; the 1016 patients assigned to the control group received usual care. The functional and health status of the patients was measured at base line and 3 and 12 months later; survival was assessed at 12 months. Subgroups of patients who might be presumed to benefit from comprehensive assessment were also studied. RESULTS: The survival rate at 12 months was 74 percent in the experimental group and 75 percent in the control group. At base line, 3 months, and 12 months the scores of the two groups on measures of functional and health status were similar. The analysis of 16 subgroups did not identify any with either clearly improved functional status or improved survival. CONCLUSIONS: In this HMO, comprehensive geriatric assessment by a consultation team, with limited follow-up, did not improve the health or survival of hospitalized patients selected on the basis of screening criteria.

Screening for balance and mobility impairment in elderly individuals living in residential care facilities.

BACKGROUND AND PURPOSE: The rapid growth of the elderly population has resulted in a corresponding rise in the number of elderly individuals who experience disability during their lifetimes. The purpose of this study was to test the usefulness of four established clinical measures of balance, gait, and subjective perceptions of fear of falling as screening methods for referring community-dwelling elderly individuals living in residential care facilities for detailed physical therapy evaluation and possible intervention. SUBJECTS: The subjects were a convenience sample of 53 elderly individuals living in two residential care facilities for the elderly. METHODS: Subjects were tested on each of four clinical measures of balance and mobility. Their performance on these measures was compared with a physical therapist's brief evaluation of disability and appropriateness for more detailed evaluation. The usefulness of these tools as screening methods was determined by calculating sensitivity and specificity levels using the physical therapist's evaluation as a standard. RESULTS: The sensitivity and specificity levels of the four clinical measures in their application as screening tests for referral to physical therapy were as follows: Berg Balance Scale, 84% and 78%; balance subscale of the Tinetti Performance-Oriented Mobility Assessment, 68% and 78%; gait speed, 80% and 89%; and Tinetti Fall Efficacy Scale, 59% and 82%. The combination of two tests, Berg Balance Scale and gait speed, yielded the highest sensitivity of 91% and the highest specificity of 70% when a subject tested positive on at least one test. CONCLUSION AND DISCUSSION: These findings indicate the feasibility of developing screening methods for referring community-dwelling elderly individuals for a detailed physical therapy evaluation based on established clinical assessment measures, with a combination of tests measuring balance and gait demonstrating the most promising results.

Physical therapy to improve functioning of older people in residential care facilities.

BACKGROUND AND PURPOSE: The purpose of this study was to determine the effectiveness of an individualized physical therapy mobility training program on the gait, balance, and functional performance of elderly individuals living in residential care facilities. SUBJECTS: Twenty-seven elderly individuals with impaired balance and difficulty performing at least one functional activity participated in the study. The subjects ranged in age from 71 to 97 years (mean = 87.1, SD = 6.7). METHODS: Balance and gait speed were assessed at baseline and following physical therapy that consisted of exercises to improve specific functional limitations. Outcomes were reassessed 1 month following completion of the physical therapy. RESULTS: Gait and balance outcomes were analyzed using a one-way repeated-measures analysis of variance. Improvement was obtained in balance, which was maintained at 1 month follow-up. Gait speed did not improve to a level of statistical significance. CONCLUSION AND DISCUSSION: After physical therapy, subjects improved in balance and functional performance. An improvement in gait speed may require a longer duration of treatment.

Feasibility and accuracy of a postcard diary system for tracking healthcare utilization of community-dwelling older persons.

OBJECTIVE: To test the feasibility of and to validate a self-report weekly postcard diary of health care utilization. DESIGN: Case-series and validation study. SETTING: Community-based sample of fee-for-service and health maintenance organization (HMO) patients. PARTICIPANTS: A convenience sample of 24 community-dwelling older persons who had failed a self-administered screen and were eligible for a study of outpatient comprehensive geriatric assessment consultation. MEASUREMENTS: Subjects completed and mailed in a weekly postcard diary documenting medical, counseling, or rehabilitation therapy visits. If a subject did not respond within 10 days after the end of the week, a telephone call was placed to gather the information. For a subset of 10 subjects who were HMO enrollees, all records were reviewed to determine accuracy of the postcard diaries. RESULTS: Of the 24 subjects enrolled, one HMO enrollee dropped out following hip surgery after 4 weeks of completing diaries. The remaining 23 subjects (96% of total entered) provided complete information for 12 weeks. Telephone follow-up to either obtain or clarify utilization information was required for 22% of subjects. For the subset of 10 HMO subjects, seven underreporting, two overreporting, and one incorrect day errors were detected-a total of 10 errors representing 9% of diaries and 1.3% of patient-days. Kappa as a measure of agreement between the two methods (self-report and chart review) was 0.82 (P < .0001). Compared with chart review, the diary report was 75.0% sensitive and 99.8% specific. Positive and negative predictive values were 91.3% and 99.2%, respectively. CONCLUSION: These findings suggest that a postcard diary system with telephone follow-up is both a feasible and reasonably accurate method of tracking health care utilization by community-dwelling older persons, although a small percentage will be unable to adhere to this method.

Measuring physical function in community-dwelling older persons: a comparison of self-administered, interviewer-administered, and performance-based measures.

PURPOSE: To compare two self-administered, one interviewer-administered, and one performance-based measure of physical function in community-based older persons. METHODS: Eighty-three subjects were recruited from meal sites, senior recreation centers, and senior housing units for a comprehensive geriatric assessment program. At the time of screening, study participants self-administered the Functional Status Questionnaire (FSQ) and were administered the Katz Activities of Daily Living (ADL) and the Older Americans Resources and Services Instrumental Activities of Daily Living (OARS-IADL) instruments by interview. Participants also completed the Physical Performance Test (PPT) and were given the Medical Outcomes Study SF-36 to self-administer on site or at home and return by mail. RESULTS: All 83 subjects completed FSQ, Katz ADL, OARS-IADL, and PPT; 72 returned SF-36 forms. Correlations between the two self-administered physical function measures (FSQ and SF-36) were higher than between self-administered and interviewer-assessed (ADL and OARS-IADL) or performance-based (PPT) measures. When assessed for construct validity, the self-administered, OARS, and PPT measures had comparable correlations with role limitations as a result of physical health problems, but relationships between physical functional status measures and other SF-36 measures of health were inconsistent. CONCLUSION: The relationships between commonly used self-administered, interviewer-administered, and performance-based measures of physical function were inconsistent and weak, suggesting that these instruments are not measuring the same construct.

Attitudes of beginning medical students toward older persons: a five-campus study. The University of California Academic Geriatric Resource Program Student Survey Research Group.

OBJECTIVE: To examine the attitudes of beginning medical students toward older persons and their medical care. DESIGN: Cross-sectional survey. SETTING: Five University of California medical schools. PARTICIPANTS: Beginning medical school students from the Class of 1994. MEASUREMENTS: Demographic characteristics, personal contacts with older persons, and previous coursework or research experience with older persons were assessed. Knowledge with regard to aging was measured with a group of 10 questions, which were modified from the Facts on Aging Quiz. The attitudes of students toward older persons were assessed using the Aging Semantic Differential (ASD), the Maxwell-Sullivan Attitude Scale (MSAS), and two case scenarios. RESULTS: Ninety-two percent of the participants (554 of 603) responded; 93% of these responses were usable. Students were much less likely to admit an acutely ill 85-year-old woman to an intensive care unit, intubate her, and treat her aggressively than they were to treat an acutely ill 10-year-old girl with underlying chronic leukemia. In multivariate models, male gender and younger student age were both independently predictive of less favorable attitudes regarding a 70-year-old person on the ASD Instrumental-Ineffective subscale. Asian-Americans and males had less favorable attitudes on the Autonomous-Dependent and the Personal Acceptability-Unacceptability subscales. More knowledge with regard to aging was predictive of more favorable attitudes on the Autonomous-Dependent and Personal Acceptability-Unacceptability subscales. Male gender and Asian-American ethnicity were significantly associated with less favorable attitudes on the two scales derived from the MSASs. Students who had previously visited a long-term care facility were more likely to disagree that it takes too much time to care for older persons. CONCLUSION: Beginning medical students have already formed some unfavorable attitudes about older persons. Few independent predictors (either sociodemographic or students' previous experiences) of student attitudes could be identified that would help in the selection of students who had more favorable attitudes toward older persons. Hence, attempts to generate physicians with good attitudes must rely on curricular efforts during medical school and residency training.

Fellowship training in geriatrics.

Geriatric medicine fellowships have begun to earn a berth in most department of medicine across the country. After 1994, initial certification of Added Qualification in Geriatric Medicine (AQGM) will require a period of geriatrics fellowship training. The requirements for accreditation of fellowship programs have been carefully developed and reflect emerging trends in graduate medical education. Nevertheless, recruitment into geriatrics fellowship programs has fallen far short of that in many other internal medicine fellowship programs. The lack of adequate reimbursement for the time and the evaluation and management skills needed to care for frail elderly patients prevents geriatrics from being an attractive career. On the other hand, several factors suggest a brighter future: the satisfaction of graduates of geriatrics fellowship programs, the increasing demand for clinical services for the elderly, and the wide open opportunities for research in this field.

Functional profiles of healthy older persons.

To learn whether the percentage of time spent at different functional levels varies as a function of age, we studied 44 older (mean age 70 years) and 46 younger (mean age 27 years) urban, community-dwelling volunteers who participated in a study of normative ageing of the cardiovascular system. Each subject completed one 24-hour activity diary which was coded using a standardized scoring system for functional activity levels and energy levels. Compared with younger persons, older persons spent larger percentage of their day performing basic (BADLs) and intermediate activities of daily living (IADLs) and less time in physical advanced activities of daily living and sleeping. Older women spent more time than younger women performing BADLs and more time than younger women or older men performing IADLs. These findings support the concept of functional changes associated with healthy ageing which may be more pronounced in women. Our results may also reflect a cohort effect that may disappear with the change of traditional sex roles.

Inpatient geriatric evaluation and management units (GEMs) in the veterans health system: diamonds in the rough?

BACKGROUND: Research suggests that inpatient geriatric evaluation and management units (GEMs), which undertake interdisciplinary diagnosis to improve the health of frail elderly patients, are effective. The Department of Veterans Affairs (VA) helped pioneer U.S. GEMs and mandates that every facility shall have a GEM by 1996. We conducted a population survey of VA GEMs in 1991 to assess their dissemination. METHODS: Various organizational and performance characteristics of GEMs were entered in a data base derived from a piloted questionnaire and administrative records. Basic criteria from consensus reports were used to classify and compare "standard" and "nonstandard" GEMs. The criteria covered performance of assessment, team structure, patient selection, GEM location, and treatment functions. We analyzed the effect of GEM type and other factors on length of stay and placement. Reasons for closure of GEMs inactive in 1991 were recovered, and GEMs active in 1991 but later closed are described. RESULTS: As of 1991, 41 of 73 GEMs were classified as standard, and 32 nonstandard. Standard compared to nonstandard GEMs had shorter stays (25.4 vs 69.9 days; p < .001), higher home discharge rates (63.4% vs 40%; p < .001), and lower nursing home placement rates (19.1% vs 40.3%; p < .001). Eleven hospitals had closed their programs by 1991. By 1993, 6 additional GEMs had closed; all were nonstandard in 1991. CONCLUSIONS: Most VA GEMs are organized according to basic consensus standards, and appear to be discharging most patients back to the community after reasonably short stays. However, various resource constraints are common, apparently reflected in nonstandard organization and GEM closure. Additional work is needed to monitor GEM proliferation, implementation, and performance in and out of the VA system.
