Medical care for nursing home residents: differences by dementia status. Epidemiology of Dementia in Nursing Homes Research Group.

OBJECTIVE: To understand the use of medical services by nursing home residents. DESIGN: Descriptive, longitudinal study comparing medical service use of residents by dementia status and describing the use of medical services following detection of fever or infection. SETTING: Fifty-nine randomly selected nursing homes in Maryland from 1992 to 1995. PARTICIPANTS: 2,153 residents admitted to one of 59 randomly selected nursing homes. MEASUREMENT: A panel of psychiatrists and neurologists ascertained dementia based on review of medical records, interview data with significant others and nursing staff, and results of a cognitive exam. Medical service use was abstracted from medical records. BACKGROUND: Understanding the use of medical services by nursing home residents as distinct from services provided by the nursing home is important, particularly as new medical care models are tested. This study compares the medical service use of residents by dementia status and describes the use of medical services following detection of fever or infection. RESULTS: Residents with dementia compared with those without dementia had lower annual rates of physician visits (10.2 vs 12.7, P < .001) and hospitalizations (0.9 vs 1.2, P < .001), virtually the same rate of emergency department visits, and similar lengths of stay in the hospital. Subsequent to infection, a lower proportion of residents with dementia had either a physician visit, an emergency department visit, or a hospital admission compared with residents without dementia (27.2% vs 32.2%, P < .001). In 87% of infections, an antibiotic was used, implying meaningful contact with a physician. Residents with dementia compared with those without dementia had fewer physician visits subsequent to fevers (20.6% vs 29.9%, P < .001) and infections (21.8% vs 27.5%, P < .001). CONCLUSIONS: The association of less medical service use by individuals with dementia compared with those without dementia may reflect differences in health status or implicit end-of-life decision-making and a proclivity toward less-aggressive treatment for these individuals.

Satisfaction with health care of dually eligible older beneficiaries.

Satisfaction with health care was compared for dually eligible older beneficiaries receiving care in three settings: a managed care organization (MCO) that is at risk for providing Medicare and Medicaid benefits (n = 200); the fee-for-service (FFS) sector in the same ZIP Code (n = 201); and respondents to the national Medicare Current Beneficiary Survey (MCBS) (n = 531). Patients in the MCO were more likely to be highly satisfied in three domains--global quality, access to care, and technical skills--compared with patients in the local and national FFS study groups but fewer were highly satisfied with the interpersonal manner of their providers.

The Psychogeriatric Assessment and Treatment in City Housing (PATCH) program for elders with mental illness in public housing: getting through the crack in the door.

Psychogeriatric Assessment and Treatment in City Housing (PATCH) is an outreach program targeting elderly public housing residents who need mental health care. The PATCH model relies on educating housing personnel to serve as case finders, providing in-home psychiatric evaluation and treatment, and addressing medical and social comorbidities through case management by psychiatric nurses. An examination of PATCH interventions suggests that the program's success is due to its emphasis on: (1) educating patients, housing personnel, and caregivers about patients' illnesses and need for treatment and support; and (2) coordinating care among housing staff members, patients' caregivers and their primary medical providers.

Determinants of physical activity initiation and maintenance among community-dwelling older persons.

BACKGROUND: Understanding determinants of initiation and maintenance of an active lifestyle among older individuals is of great concern to public health because of the increasing evidence that lifestyle may alter the course of frequently occurring chronic diseases. METHOD: Two thousand five hundred seven community-dwelling Medicare beneficiaries age 65 and over were interviewed at three points over 4 years regarding their physical activity, defined as a self-report of walking briskly, gardening, or heavy housework at least three times a week. Extensive data were also collected on health status, health services use, sociodemographics, and, at the final interview, self-mastery, importance of various factors in the decision to be physically active, and interaction with their physician regarding physical activity. Determinants of initiation and maintenance of physical activity were identified using logistic regressions. RESULTS: Forty-one percent maintained an active lifestyle; 12% initiated an active lifestyle; 22% declined to become sedentary; 25% were sedentary at all observation. Predictors of both initiation and maintenance of physical activity were younger age, moderate to excellent health, and the patient's belief that physical activity was important to his/her health. Among the 301 patients who initiated activity, 40% said their physician was a very important influence. CONCLUSIONS: Strengthening the belief of older individuals in the benefits to their health of physical activity holds promise for increasing the proportion of community-dwelling older persons who move from a sedentary lifestyle to a more physically active lifestyle and for maintaining such activity.

Predictors of nursing home placement among elderly public housing residents.

This study examines risk factors for nursing home placement among elderly residents of public housing. Data on residents of six urban public housing developments for elderly persons (weighted n = 881) were analyzed by using logistic regression procedures to determine the predictors of nursing home placement during a 28-month period. Four baseline indicators of need were identified: greater impairment in instrumental activities of daily living, cognitive disorder, high scores on the General Health Questionnaire, and psychotic disorder. Thus, functional status and mental morbidity are major contributors to nursing home placement in this setting.

Ascertaining dementia by expert panel in epidemiologic studies of nursing home residents.

A new method for ascertaining dementia in epidemiologic research and the results of a study to evaluate it are described. The method relies on an expert panel of clinicians reviewing clinically relevant information collected by lay evaluators to arrive at a diagnosis based on DSM-III-R criteria. The approach was developed to study dementia in a statewide sample of over 2400 new admissions to 59 nursing homes in Maryland. Expert panel ascertainment of dementia was compared to that obtained by direct clinical evaluation for 100 nursing home residents. Agreement between the panel and direct assessment was 76% (kappa = 0.59) using a three-category classification of dementia, no dementia, and indeterminate. This ascertainment strategy provides an alternative to methods currently in use and is particularly well-suited for populations with a high prevalence, in those dispersed over large geographic areas, and when timely, cost-effective evaluations are required.

The effect among older persons of a general preventive visit on three health behaviors: smoking, excessive alcohol drinking, and sedentary lifestyle. The Medicare Preventive Services Research Team.

BACKGROUND: The U.S. Congress mandated evaluations, initiated in 1989, to determine whether extending Medicare benefits to include preventive services would improve health status, reduce costs of care, and improve health risk behaviors of beneficiaries. METHODS: The Johns Hopkins Medicare Preventive Services Demonstration was a randomized trial in which Medicare beneficiaries were assigned either to an intervention group that was offered yearly preventive visits for 2 years and optional counseling visits to their primary care provider or to a control group that received usual care. This report describes the effect of the intervention over a period of 2 years on smoking, problem alcohol use, and sedentary lifestyle. RESULTS: Differences were observed between the intervention and control groups in the extent to which changes occurred in smoking and problem alcohol use, but none of the differences was statistically significant. The proportion of smokers who quit was higher in the intervention group than in the control group (24.2 vs 17.9%, P = 0.09). However, a higher proportion of problem drinkers in the control group improved (67.1 vs 57.0%, P = 0.183). There was virtually no difference between the intervention and the control groups in the proportion with improvement in sedentary lifestyle. CONCLUSIONS: This study demonstrates the difficulty of bringing about health behavior change in older patients in the course of a yearly preventive visit for 2 years with their primary care physician when the visit encompasses screening and immunizations, as well as health behavior counseling directed by the physician. Further study is required to determine whether a more intense program of counseling for health behavior change among older persons by their primary care providers would be effective.

Neuroleptic use and behavioral disturbance in nursing homes: a 1-year study.

This article discusses a longitudinal study of change in disruptive behaviors among nursing home residents treated with neuroleptics compared with those not treated with neuroleptics. Observations were made of 201 participants on admission to and after 1 year in eight skilled nursing facilities. Nine disruptive behaviors were measured using the Psychogeriatric Dependency Rating Scale with nursing assistants. Neuroleptic use was documented from medication records. Odds ratios are reported for the association of behavior at baseline and use of neuroleptics on nine problem behaviors. For those who received neuroleptics during the year, there was greater change in both developing and resolving disruptive behaviors than for those not receiving neuroleptics. For both groups, restless or pacing behavior and belligerent behavior manifested by refusing instructions changed the most, both in developing and in apparently resolving. Our results show that change in disruptive behaviors occurs among nursing home residents regardless of neuroleptic use, but it occurs more frequently among those who receive neuroleptic medication. Knowledge of which disruptive behaviors are most likely to resolve or develop is important in training nursing home staff to cope with the behaviors as well as in planning interventions that may modify such behaviors.

Extended coverage for preventive services for the elderly: response and results in a demonstration population.

OBJECTIVES: This study was undertaken to test the acceptability of preventive services under Medicare waivers to a community-dwelling population aged 65 and over and to examine the effect of such services on health. METHODS: Medicare beneficiaries and designated primary care providers were sampled, and beneficiaries were screened and surveyed. A total of 4195 individuals were then randomized into intervention or control groups. Those in the intervention group were offered free preventive visits (under waivers) to their physicians. A follow-up survey of the entire group was administered after completion of the intervention. RESULTS: Sixty-three percent of the intervention group made a preventive clinical visit, and about half of them a counseling visit. For men, being married and having a solo practitioner were positively associated with accepting the intervention services, while for women, having had a mammogram, having a confidant, having a high school education, and having a female practitioner were so associated. The intervention group showed a greater health benefit than did the control group and had a significantly lower death rate: 8.3% vs 11.1%. CONCLUSIONS: Older individuals will respond to preventive programs, and such services will result in modest health gains.

Preventive services for the elderly: would coverage affect utilization and costs under Medicare?

OBJECTIVES: This study was undertaken to determine whether adding a benefit for preventive services to older Medicare beneficiaries would affect utilization and costs under Medicare. METHODS: The demonstration used an experimental design, enrolling 4195 older, community-dwelling Medicare recipients. Medicare claims data for the 2 years in which the preventive visits occurred were compared for the intervention (n = 2105) and control (n = 2090) groups. Monthly allowable charges for Part A and Part B services and number of hospital discharges and ambulatory visits were compared. RESULTS: There were no significant differences in the charges between the groups owing to the intervention, although total charges were somewhat lower for the intervention group even when the cost of the intervention was included. Charges for both groups rose significantly as would be expected for an aging population. A companion paper describes a modest health benefit. CONCLUSIONS: There appears to be a modest health benefit with no negative cost impact. This finding gives an early quantitative basis for the discussion of whether to extend Medicare benefits to include a general preventive visit from a primary care clinician.

Urinary incontinence in nursing homes: incidence, remission and associated factors.

OBJECTIVE: To determine the incidence and remission rates of daytime urinary incontinence (UI) in a cohort of newly admitted nursing home (NH) residents. DESIGN: Prospective cohort study. SETTING: Eight proprietary NHs in Maryland. SUBJECTS: Four hundred thirty new admissions age 65 or older who were participants in a larger prospective study of mental morbidity and adjustment to the NH. MEASURES: Nurses aides' reports of continence status, psychiatric examinations, and nursing staff assessments of mobility at 2 weeks, 2 months, and 1 year after NH admission. RESULTS: The prevalence of daytime UI at admission was 39% in both females and males. Among the 293 members (68%) of the admission cohort remaining in the NHs 2 months after admission, the incidence of daytime UI was 27% (21% in females, 51% in males); daytime UI resolved in 23% (24% in females, 20% in males). Among the 178 members (41%) of the admission cohort remaining in the NHs 1 year after admission, the incidence of daytime UI between 2 months and 1 year after admission was 19% (16% in females, 46% in males); daytime UI resolved in 22% (23% in females, 14% in males). The continence status of about two-thirds of residents remaining in the NH at 1 year after admission was stable over time: 22% had daytime UI, and 42% were continent at all three data collection points. The development of daytime UI was associated with male sex, the diagnosis of dementia, fecal incontinence, and the inability to ambulate or transfer independently. Resolution of daytime UI was associated with the absence of these characteristics. CONCLUSIONS: Despite limitations attributable to the method of defining UI and potential biases related to the attrition of the admission cohort over time, this is the first large prospective study to examine the incidence and remission patterns of daytime UI among NH residents. The strong association between UI and dementia was validated for the first time by direct psychiatric examinations. Sex and mobility are also closely associated with the development and remission of UI in this setting. This study provides some valuable data that can be used to assess the impacts of the recently developed Resident Assessment Protocol for UI and Agency for Health Care Policy and Research Clinical Practice Guidelines.

Assessing the use of medications in the elderly: methods and initial experience in the Cardiovascular Health Study. The Cardiovascular Health Study Collaborative Research Group.

The Cardiovascular Health Study (CHS), a cohort study of risk factors for coronary heart disease and stroke, recruited 5201 community-dwelling adults aged 65 years or older. To assess the prevalence of medication use at baseline, we used the method of medication inventory and transcribed information about drug names and doses from prescription bottles. Using a specially-written computer program, persons without a knowledge of drug nomenclature coded 10,511 (89%) of the 11,846 medicines entered. We compared the results of the medication inventory and answers to questions on specific medications for reliability and validity. The use of beta-blockers and beta-agonists assessed by the method of medication inventory, but not by the method of directed recall, was associated with a significant effect on mean heart rate. Among 5197 participants with medication data, 76.1% were taking at least one medicine, and the mean number of drugs per person was 2.28. Among those with a reported history of high blood pressure, participants with cardiovascular disease (CVD) were more likely to be treated, and they were more likely to be taking beta-blockers and calcium-channel blockers than those without CVD. Daily aspirin use was also more common among those with CVD (30.5% of women and 43.2% of men) than among those without CVD (14.0% of women and 14.0% of men). The prevalence of post-menopausal estrogen use differed significantly among the four clinical centers (range = 5.5%-22.5% of women). We conclude that this method of assessing medications was easy to use and provided estimates of exposure to drugs that may affect risk of cardiovascular disease.

The role of mental morbidity in the nursing home experience.

The history of a newly admitted cohort to eight nursing homes (N = 454) was studied prospectively over the first year of residence. Data were gathered at admission, 2 months, and 1 year, and included full psychiatric examination and staff reports of behavior. Chart reviews collected additional data on preadmission and postdischarge information. At admission, 80% of the population had mental illnesses, 60% of which were dementia, and about half of demented patients had other complicating mental illnesses. Use of mixed-effects linear model analysis revealed significant associations of mental morbidity, restraints, and psychotropic medication with behaviors indicative of noncoping and nonadaptation to the nursing home settings.

A longitudinal approach to modeling outcomes in a nursing home study.

Recent developments in longitudinal statistical methodology have improved our ability to model dynamic processes such as adaptation to nursing homes. Longitudinal observations provide information on individual patterns of change and factors affecting them. However, longitudinal analyses are often complicated by unequal periods of observation and individual variability in patterns of change. This paper demonstrates the use of a linear mixed-effects model to study adaptation in a longitudinal nursing home study with different numbers of repeated measurements for each individual because of discharges, transfers, and mortality.

Mental illness and the use of restraints in nursing homes.

Using data from 441 newly admitted nursing home residents, we examined whether the diagnoses of mental illnesses, as well as other resident characteristics, were associated with use of physical restraints in both high restraint and low restraint use homes. Predictors of restraint use during both the first month and the first year of admission were inability to transfer and having a combination of severe ADL and cognitive impairment. Other predictors were wandering, inability to dress, symptoms of depression, and severity of cognitive impairment.

Physical restraint use and cognitive decline among nursing home residents.

OBJECTIVE: This study investigated the association between physical restraint use and decline in cognition. DESIGN: Cohort analytic study describing changes in resident characteristics. SETTING: Eight nursing homes, both urban and suburban, operated by a proprietary corporation in a large metropolitan area. PARTICIPANTS: 437 nursing home admissions, with 201 remaining at 1 year. MAIN OUTCOME MEASURES: Cognitive status was measured by geropsychiatrists, using the Folstein Mini-Mental State Exam, during a psychiatric evaluation of the resident. Daily restraint use was documented from nursing orders. Observations were made at 2 weeks, 10 weeks, and 1 year. RESULTS: Restraint use alone and in combination with neuroleptic use was associated with poor cognition. Other variables associated with poor cognitive scores were: ADL impairment, poor adaptive behavior, and longer time in the nursing home. The use of neuroleptics alone was not significant. Variables which were associated with good cognitive status were: being non-ambulatory but without dementia and having strong social support. CONCLUSIONS: These findings raise the possibility that restraint use may contribute to cognitive impairment, specifically among residents who have moderate to no cognitive impairment at admission; however, the findings do not exclude an alternative explanation that residents undergoing cognitive decline are more likely to be put in restraints. Further research is needed to understand whether factors which can be manipulated contribute to cognitive decline.
