Objective and subjective measures of the quality of managed care in nursing homes.

BACKGROUND: The number of nursing home (NH) residents enrolled in managed care plans (HMO) will increase, and there is concern that the quality of their medical care may be compromised by cost-containment pressures. In this study, we evaluated the medical care of residents enrolled in 3 health maintenance organizations (HMO) that developed specific long-term care programs. OBJECTIVES: To compare the medical care received by NH residents enrolled in HMO and Fee-for-Service (FFS) plans with both objective process of care and consumer perception (subjective) measures. To describe the relationship between the objective and subjective measures. MEASURES: Number of primary care visits per month; process of medical care for 2 geriatric tracer conditions (falls, fevers); family and residents' perceptions of the adequacy of sickness episode management; and the frequency of primary provider visits. DESIGN: Quasi-experimental. RESULTS: HMO residents received more timely and appropriate responses to falls and fevers than did FFS residents. HMO residents also received more frequent routine visits by a primary care provider team consisting of a physician and nurse practitioner. Consumer perceptions of quality did not differ between the HMO and FFS groups. Families within both groups were significantly more positive than were residents about the frequency of visits by both physicians and nurse practitioners. Within the HMO group, both families and residents were more positive about the frequency of nurse practitioner visits than were physician visits even when the frequency of visits by the 2 providers were similar. CONCLUSIONS: Although the medical care received by HMO residents was better on most objective process measures than that received by FFS residents, consumer perceptions of care did not detect those differences. NH residents and families have different perceptions about the adequacy of visits by physicians and nurse practitioners, and both families and residents appear to have different expectations concerning how often they want physicians to visit as compared with nurse practitioners.

Life-sustaining treatment decisions for nursing home residents: who discusses, who decides and what is decided?

OBJECTIVE: To evaluate whether nursing home residents and their families reported discussions about life-sustaining treatment with their physicians, the relationship between such discussions and orders to limit therapy, and predictors of physician-patient communication about life-sustaining treatment. DESIGN: Cross-sectional interviews and retrospective chart abstraction. SETTING: Three regions: West Coast, New England, Western. SAMPLE: A total of 413 nursing home residents, 363 family/surrogate interviews, and 192 resident interviews. MAIN OUTCOME MEASURES: Measured were (1) physician-resident communication about life-sustaining treatment and (2) presence of an advance directive or do not resuscitate (DNR) order in resident's chart. RESULTS: Seventy-four percent of residents had DNR orders, and 32% had advance directives; only 29% of residents reported discussions about life-sustaining treatment. Of residents with DNR orders who could have participated in discussions about life-sustaining treatment, nearly half reported they had not discussed CPR with their caregivers. Older age, longer duration of time living in nursing home, location in a New England nursing home, physician-family member discussion, and the presence of an advance directive in the medical chart were positively associated with having DNR orders. Physician-resident discussion was not associated with having a DNR order. For the subsample of interviewed residents, age and a diagnosis of cognitive impairment were negatively associated with a physician-resident discussion about life-sustaining treatment, whereas the likelihood of having a discussion increased with increasing numbers of medical diagnoses. CONCLUSIONS: Chart orders to limit therapy are common, but physician-resident discussions about life-sustaining treatments are not. Far more family members than residents report such discussions with the resident's physicians.

A randomized clinical trial of outpatient comprehensive geriatric assessment coupled with an intervention to increase adherence to recommendations.

BACKGROUND: Although comprehensive geriatric assessment (CGA) has been demonstrated to confer health benefits in some settings, its value in outpatient or office settings is uncertain. OBJECTIVE: To assess the effectiveness of outpatient CGA consultation coupled with an adherence intervention on 15-month health outcomes. DESIGN: A randomized controlled trial. SETTING: Community-based sites. PATIENTS: 363 community-dwelling older persons who had failed a screen for at least one of four conditions (falls, urinary incontinence, depressive symptoms, or functional impairment) INTERVENTION: A single outpatient CGA consultation coupled with an intervention to improve primary care physician and patient adherence with CGA recommendations. MEASUREMENTS: Medical Outcomes Study Short Form-36 (MOS SF-36), restricted activity and bed days, Physical Performance Test, NIA lower-extremity battery. RESULTS: In complete case analysis (excluding the five control group subjects who died during the follow-up period), the adjusted difference in change scores (4.69 points) for physical functioning between treatment and control groups indicated a significant benefit of treatment (P = .021). Similar benefits were demonstrated for number of restricted activity days and MOS SF-36 energy/fatigue, social functioning, and physical health summary scales. In analyses assigning scores of 0 to those who died, these benefits were greater, and significant benefits for the Physical Performance Test and MOS SF-36 emotional/well being, pain, and mental health summary scales were also demonstrated. CONCLUSIONS: A single outpatient comprehensive geriatric assessment coupled with an adherence intervention can prevent functional and health-related quality-of-life decline among community-dwelling older persons who have specific geriatric conditions.

Primary care of long-stay nursing home residents: approaches of three health maintenance organizations.

OBJECTIVE: To describe the innovative programs of three health maintenance organizations (HMOs) for providing primary care for long-stay nursing home (NH) residents and to compare this care with that of fee-for-service (FFS) residents at the same NHs. DESIGN: Cross-sectional interviews and case-studies, including retrospective chart reviews for 1 year. SETTING: The programs were based in 20 community-based nursing homes in three regions (East, West, Far West). PARTICIPANTS: Administrative and professional staff of HMOs in three regions and 20 NHs; 215 HMO and 187 FFS residents at these homes were studied. MAIN OUTCOME MEASURES: Emergency department (ED) and hospital utilization. RESULTS: All HMO programs utilized nurse practitioner/physician's assistants (NP/PA), but the structural configuration of physicians' (MD) practices differed substantially. At nursing homes within each region, all three HMO programs provided more total (MD plus NP/PA) visits per month than did FFS care (2.0 vs 1.1, 1.3 vs .6, and 1.4 vs .8 visits per month; all P < .05). The HMO that provided the most total visits had a significantly lower percentage of residents transferred to EDs (6% vs 16%, P = .048), fewer ED visits per resident (0.1 vs .4 per year, P = .027), and fewer hospitalizations per resident (0.1 vs .5 per year, P = .038) than FFS residents; these differences remained significant in multivariate analyses. However, the other two programs did not achieve the same benefits on healthcare utilization. CONCLUSIONS: HMO programs for NH residents provide more primary care and have the potential to reduce ED and hospital use compared with FFS care. However, not all programs have been associated with decreased ED and hospital utilization, perhaps because of differences in structure or implementation problems.

Use of primary care teams by HMOS for care of long-stay nursing home residents.

OBJECTIVE: To characterize the use of formal primary care programs by health maintenance organizations (HMOs) for their members who are long-stay residents of nursing homes. DESIGN: Using mail survey techniques, 34 Medicare risk-contracting HMOs with the largest Medicare beneficiary enrollments were asked to complete a written questionnaire. HMOs were asked how they evaluate care in nursing home settings and whether they operate a formal primary care program for members who are long-stay nursing home residents. Those reporting they had programs were asked about the program features, participation in the program, roles performed by clinical practitioners, and clinical caseloads. Surveys were completed by 21 (61.8%) of the HMOs. PARTICIPANTS: HMO management personnel who know the primary care programs the HMOs operate in affiliated nursing homes. MEASUREMENTS: Descriptive summaries of the HMOs' responses to the survey questions were generated. For HMOs with primary care programs, caseloads of physicians and nurse practitioners were estimated using survey data reported by the HMOs. RESULTS: Eight (38.1%) of the responding HMOs operate formal primary care programs in affiliated nursing homes. HMOs with programs consider more factors than non-program HMOs in evaluating care for nursing home residents. Reasons cited most frequently for not having a program are costs and too few nursing home residents. The most common primary care program features are designated physicians and use of physician extenders. CONCLUSIONS: Survey findings point to the potential importance of formal HMO primary care programs for long-term nursing home residents, which may expand with growth in the older population and Medicare-managed care. Program adoption, however, may depend on sufficient resident participation to be financially feasible.

The predictive value of combined hypoalbuminemia and hypocholesterolemia in high functioning community-dwelling older persons: MacArthur Studies of Successful Aging.

OBJECTIVES: To examine the effect of simultaneous hypoalbuminemia and hypocholesterolemia levels on 3- and 7-year rates of mortality and decline in functional status. METHODS: In this cohort study, 937 community-based persons aged 70 to 79 years in 1988, who had high baseline physical and cognitive functioning, were classified into four groups: Group 1 (low albumin, low cholesterol), Group 2 (low albumin, normal cholesterol), Group 3 (normal albumin, low cholesterol) and Group 4 (normal albumin, normal cholesterol) using baseline blood values. Crude and multiply adjusted rates of (1) mortality (2) decline in Rosow-Breslau (RB) functional status, and (3) mortality or decline in RB functional status in 1991 and 1995 were calculated. RESULTS: Group 1 subjects had multiply adjusted relative risks (ARR) of 3.62 and 3.53 for 3-and 7-year mortality compared with Group 4. Group 1 subjects had ARRs of 3.82, 3.02, and 2.67 of 3-year mortality or decline in RB activity scale when compared with Groups 4, 2, and 3, respectively. CONCLUSIONS: Concomitant low serum cholesterol and albumin levels may identify high functioning older persons who are at increased risk of subsequent mortality and functional decline.

Drinking habits among older persons: findings from the NHANES I Epidemiologic Followup Study (1982-84). National Health and Nutrition Examination Survey.

OBJECTIVES: To describe alcohol use and its sociodemographic correlates among persons aged 65 years and older in a US probability sample. DESIGN: Cross-sectional analysis of a national probability sample-based cohort study. SETTING: Multiple sites throughout the United States. PARTICIPANTS: A total of 3448 persons aged 65 and older who participated in the first wave of the NHANES I Epidemiologic Followup Study (1982-84). MEASUREMENTS: We describe the alcohol use behaviors and demographic characteristics of 3448 persons aged 65 and older. Least squares regression models were used to assess associations between older persons' sociodemographic characteristics and alcohol use. RESULTS: Sixty percent of the sample reported having 12 or more drinks of alcohol in at least 1 year of their lives. Seventy-nine percent of these older drinkers were currently drinking. Twenty-five percent of all drinkers drank daily (31% men, 19% women). Using gender-specific definitions (men >2 drinks/day; women >1 drink/day), 16% of men drinking alcohol and 15% of women drinking alcohol were heavy drinkers. Younger age, male gender, and higher income were associated with greater alcohol use. CONCLUSIONS: Most older persons who ever drank alcohol in their lifetimes were currently drinking. In addition, a substantial number of older persons were drinking currently at levels that may place them at risk of adverse health consequences.

Perceived efficacy in patient-physician interactions (PEPPI): validation of an instrument in older persons.

OBJECTIVE: To develop and validate a brief instrument--the Perceived Efficacy in Patient-Physician Interactions Questionnaire (PEPPI)--to measure older patients' self-efficacy in obtaining medical information and attention to their medical concerns from physicians. DESIGN: Two consecutive validation surveys. SETTING: Eleven senior multipurpose centers in Los Angeles County California. POPULATION: A convenience sample of 163 community-dwelling older persons (Survey 1: n=59, mean age=77.1 years, 76.3% female; Survey 2: n=104, mean age=77.4 years, 57.7% female). MEASURES: The 10-item PEPPI, subscales of the Patient Satisfaction Questionnaire, the Medical Outcomes Study (MOS) Coping Scale, the Mastery Scale, and global self-reported health and restricted activity days items. RESULTS: The full 10-item and a 5-item short form of PEFPI demonstrated Cronbach's alphas of 0.91 and 0.83, respectively. PEPPI demonstrated discriminant and convergent validity as hypothesized, correlating negatively with avoidant coping (r=-.27, P=.001) and positively with active coping (r=.17, P=.03) and with patient satisfaction with physician interpersonal manner (r=.49, P < .0001) and communication (r=.51, P < .0001) (values from the overall sample). Further, in the second survey, PEPPI correlated positively with self-reported health (r=.42, P < .0001), education (r = .24, P=.01) and self-mastery (r=.29, P=.01) and negatively with restricted activity days (r=-.25, P=.01). PEPPI-5 demonstrated correlations similar in magnitude, direction, and statistical significance. CONCLUSION: In either the 5- or 10-item version, PEPPI is a valid and reliable measure of older patients' perceived self-efficacy in interacting with physicians. This instrument may be useful in measuring the impact of empowerment interventions to increase older patients' personal sense of effectiveness in obtaining needed health care.

Hearing loss in community-dwelling older persons: national prevalence data and identification using simple questions.

OBJECTIVE: To estimate the prevalence of hearing loss among community-dwelling older persons according to clinical criteria and to develop a brief self-report screening instrument to detect hearing loss. DESIGN: Survey. SETTING: National probability sample of noninstitutionalized older persons. PARTICIPANTS: A total of 2506 persons aged 55 to 74 who participated in the National Health and Nutrition Examination Survey. MAIN OUTCOME MEASURES: Hearing loss as defined by Ventry and Weinstein (VW) criteria and by the High Frequency Pure-Tone Average (HFPTA) scale. RESULTS: Hearing loss by VW criteria was present in 14.2% and by HFPTA criteria in 35.1% of those surveyed. The prevalence increased with advancing age and was higher among men and those with less education. A logistic regression model identified six independent factors for hearing loss by VW criteria: age > or = 70 years (adjusted odds-ratio (AOR) 2.7, 95% confidence interval (95% CI) 1.6, 4.4), male gender (AOR 3.0, 95% CI 1.9, 4.8), < or = 12th grade education (AOR 3.8, 95% CI 1.8, 7.7), having seen a doctor for deafness or hearing loss (AOR 8.9, 95% CI 5.3, 14.9), unable to hear a whisper across a room (AOR 3.2, 95% CI 2.0, 5.1), and unable to hear a normal voice across a room (AOR 6.2, 95% CI 2.6, 14.9). A clinical scale based on the logistic model had 80% sensitivity and 80% specificity in predicting hearing loss using VW criteria and 59% sensitivity and 88% specificity in predicting hearing loss using HFPTA criteria. CONCLUSIONS: Hearing loss, as defined by two clinical criteria, is common and can be screened for accurately using simple questions that assess sociodemographic and hearing-related characteristics.

Development and validation of a geriatrics attitudes scale for primary care residents.

OBJECTIVE: To develop and validate an instrument measuring attitudes toward older persons and caring for older patients. DESIGN: Cross-sectional and longitudinal studies. SETTING: An academic medical center. PARTICIPANTS: Initial Study: 121 primary care residents (n = 96), fellows (n = 14), and faculty (n = 11) participated in instrument development in 1995. Longitudinal Study: 95 residents (n = 87) and fellows (n = 8) of the initial cohort participated in the 1996 follow-up study, and 61 of the initial cohort (57 residents and 4 fellows) participated in the 1997 follow-up study. Cross Validation Study: 96 first-year residents (n = 78) and fellows (n = 18) participated in this study. MEASUREMENTS: A 14-item geriatrics attitudes scale was developed. The items were selected from a pool of 37 items administered to the 121 participants in the initial study. RESULTS: The instrument demonstrated high reliability (Cronbach's alpha = .76) and known-groups and construct validity. Attitudes were progressively more positive with more medical training (P < .001), and residents with greater career interest in geriatrics scored higher than those less interested (P = .007). Cross validation results supported the reliability and validity of the instrument. Longitudinal data showed significantly different trends of attitude changes among groups of residents and fellows over a 2-year period. CONCLUSIONS: The 14-item geriatrics attitudes scale developed in this study shows sound reliability, validity, and sensitivity to change among primary care residents. The performance of other groups of medical trainees and the relationship of attitude changes to specific medical training warrant further investigation.

Geriatric assessment in oncology.

With the anticipated growth in the numbers of elderly persons, a higher prevalence of cancers among older persons is expected; as a result, oncologists will treat larger numbers of older persons in their practices. Clinicians caring for older persons with cancer must recognize the heterogeneity of the elderly population and focus their assessments and care plans accordingly. The author reviewed literature and drew conclusions regarding geriatric assessment in several key areas: the medical, cognitive, affective, functional economic, and environmental status of patients; social support for patients; and advance directives. They concluded that for younger and healthier seniors, simple probes for the presence of common geriatric problems may suffice, but traditional means of medical assessment should be supplemented by brief screening for common geriatric conditions and nonmedical issues that are of particular relevance to the health of older persons. Assessment instruments can be used to guide these brief evaluations, but results must be interpreted in the context of the limitations of the instruments used. Patients who are frail or at high risk for functional decline or nursing home placement should receive more extensive evaluation by individual practitioners or by a multidisciplinary team of health care professionals who can provide comprehensive geriatric assessment. By broadening their assessment skills to include domains that are beyond traditional internal medicine and oncology training, oncologists can better serve their older cancer patients.

Does estrogen prevent skin aging? Results from the First National Health and Nutrition Examination Survey (NHANES I)

OBJECTIVE: To evaluate the relation between noncontraceptive estrogen use and skin wrinkling, dryness, and atrophy. DESIGN: Cross-sectional analysis of a national probability sample-based cohort study. SETTING: Multiple community sites throughout the United States. PARTICIPANTS: Postmenopausal women (n = 3875) aged 40 years and older at baseline. MEASUREMENTS: Skin conditions (wrinkling, dryness, and atrophy) were ascertained using a uniform clinical examination by trained dermatology resident physicians. Self-reported use of estrogen before the baseline examination, sunlight exposure, and smoking history were obtained by standardized interview. Body mass index, a measure of weight in kilograms divided by the square of the height in meters, was evaluated in uniform examination clothing. RESULTS: Mean (+/-SD) age of the participants was 61.6 (+/-9.0) years and mean (+/-SD) number of years since menopause was 15.6 (+/-9.4). Most were white (83.7%), the remainder being African American (15.9%) or another race (0.4%). Atrophy was present in 499 (16.2%), dry skin in 1132 (36.2%), and wrinkled skin in 880 women (28.2%). The prevalence of all 3 skin conditions was lower in African American women compared with white women. Information on hormone use was available for 3403 participants (88%). Among all women, after adjustment for age, body mass index, and sunlight exposure, estrogen use was associated with a statistically significant decrease in the likelihood of senile dry skin (odds ratio, 0.76; 95% confidence interval, 0.60-0.97). The odds of wrinkling were substantially lower in estrogen users, adjusted for age, body mass index, and sun exposure (odds ratio, 0.68; 95% confidence interval, 0.52-0.89) and additionally for smoking (odds ratio, 0.67; 95% confidence interval, 0.44-1.01). In multivariable models, estrogen use was not associated with skin atrophy. CONCLUSION: These results strongly suggest that estrogen use prevents dry skin and skin wrinkling, thus extending the potential benefits of postmenopausal estrogen therapy to include protection against selected age- and menopause-associated dermatologic conditions.

Development and validation of a geriatrics knowledge test for primary care residents.

This study reports the development and preliminary validation of an instrument to measure geriatrics knowledge of primary care residents. A 23-item test was developed using questions selected from the American Geriatrics Society's Geriatrics Review Syllabus. Ninety-six internal medicine and family practice residents, 14 geriatrics fellows, and 11 geriatrics faculty members participated in the study. Findings support the reliability (Cronbach's alpha = 0.66) and validity (content and "known groups") of this short test. Predictive validity and sensitivity of the test to changes in knowledge will have to be further explored as residents progress through their training.

The performance of simple instruments in detecting geriatric conditions and selecting community-dwelling older people for geriatric assessment.

BACKGROUND: comprehensive geriatric assessment (CGA) appears to be less effective when performed in outpatient clinics than in hospital settings. The effectiveness of outpatient CGA might be improved by selectively targeting frailer community-dwelling elderly people. The purpose of this study was to evaluate the clinical performance of rapidly-administered standard screening measures for geriatric syndromes in selecting community-dwelling older people for outpatient CGA. METHODS: urban-dwelling older people were screened for CGA at community sites using a self-administered questionnaire containing standardized measures for each of four geriatric target conditions: depression, urinary incontinence, falls and functional impairment. The study sample included all 150 consecutive subjects who were screened, failed on one or more of the four target criteria and completed community-based, academically administered CGA. Diagnostic accuracy of the screening instruments was assessed using CGA diagnoses as the 'gold standard'. In addition, patients' potential for benefiting from CGA was determined by whether they received major medical recommendations for further evaluation or treatment. RESULTS: after completing CGA, 60.2% of those failing on functional impairment, 53.5% of those failing on depression, 30.7% of those failing on falls and 92.7% of those on urinary incontinence, were confirmed as having these or highly related conditions as clinical problems. Overall, 81.3% of the subjects completing CGA received the least one major recommendations for further medical intervention; most of these recommendations (79.5%) were for a target-related condition and the further remainder (20.5%) addressed another significant medical condition. CONCLUSION: simple screening instruments used in community settings have variable degrees of accuracy, but may be markers for frailty and thus can identify older people likely to benefit from geriatric assessment.

Correlates of hypoalbuminemia in community-dwelling older persons.

To identify easily ascertainable sociodemographic and health characteristics that are associated with hypoalbuminemia in community-dwelling older persons, we used data from the first National Health and Nutrition Examination Survey. This population-based stratified probability sample survey included 4728 persons aged 55-74 y. We defined hypoalbuminemia in two ways: < 35 g/L (1.2% of the sample) or < or = 38 g/L (7.9% of the sample) and used multivariate logistic models to identify independent predictors of hypoalbuminemia. Older age; receiving welfare; a condition interfering with eating; vomiting > or = 3 d/mo; previous surgery for gastrointestinal tumor; self-reported heart failure; recurring cough attacks; feeling tired or wornout; edentulous, fair, or poor condition of teeth; little or no exercise; a low-salt diet; trouble chewing meat; self-reported protein albumin, blood, or sugar in urine; and current cigarette smoking were independently associated with albuminemia (< or = 38 g/L) or progressively lower albumin concentrations < 40 g/L. Persons with 3-5 of these factors (51.5% of the sample) had an odds ratio of 2.73 (95% CI: 1.64, 4.54) and those with > or = 6 factors (9.4% of the sample) had an odds ratio of 6.44 (95% CI: 3.49, 11.86) of albuminemia < or = 38 g/L compared with those with 0-2 risk factors (39.1% of the sample). These findings suggest that several easily assessed sociodemographic, lifestyle, and disease-related factors are associated with hypoalbuminemia and might be valuable items to include on general health surveys to identify older persons who have this marker of poor health status.

Determinants of patient adherence to consultative comprehensive geriatric assessment recommendations.

BACKGROUND: In consultative models of Comprehensive Geriatric Assessment (CGA), lack of implementation of CGA recommendations is well documented and appears to be a potential explanation for negative findings. The purpose of this study is to identify patient determinants of adherence to recommendations received from a community-based CGA consultative model program. METHODS: Subjects (N = 139) received self-care and/or physician-initiated CGA recommendations and were interviewed three months later to determine adherence with the most important recommendation, and health belief, communication, and social support factors associated with adherence. Independent variables were organized into the Andersen Behavioral Model for analysis. RESULTS: At the bivariate level, one predisposing factor (intention) and six enabling factors (low difficulty level, high support, high utility, high self-efficacy, agreement on the importance of the recommendation and good specific communication about the recommendation) were significant determinants of adherence. Two functional health measures and seriousness of the target condition of the recommendation were significant need factors. In the final logistic regression model, one predisposing variable (intention), one enabling variable (utility), and one need factor (high functional status), and two interaction terms significantly predicted adherence. CONCLUSION: CGA recommendations that are seen as worthwhile, not too much trouble, and able to be accomplished are the most likely to be initiated. Older adults with relatively higher functional levels are also more likely to follow through with CGA recommendations even though their needs may be lower. We found the Andersen Behavioral Model useful in the analysis of factors associated with adherence behavior to consultative CGA recommendations.
