MDS Cognitive Performance Scale

Functional status and clinical correlates in cognitively impaired community-living older people

We describe the prevalence of cognitive impairment in a population of community-living older people, its association with functional decline, and degree of comorbidity. In addition, we examined the relationship between different levels of cognitive impairment and mortality. We conducted an observational study of 1787 patients aged 65 years and above with any degree of cognitive impairment. Patient data were collected with the Minimum Data Set for Home Care. More than 50% of patients had some level of cognitive impairment, which correlates with the degree of physical frailty. On the contrary, patients with cognitive impairment appear to have fewer comorbid conditions and are less likely to receive medications than patients with normal cognitive status. In particular, hypertension, congestive heart failure, chronic obstructive pulmonary disease, cancer, diabetes mellitus, and osteoporosis are found more frequently among patients with normal mental status compared with those showing some level of cognitive defects. Yet, more severe cognitive impairment is associated with a higher mortality rate. Demented patients are characterized by a high prevalence of functional disability and by increased mortality. This increased morbidity and mortality rate is associated with a lower prevalence of comorbid clinical conditions and drug use, relative to patients with normal cognitive performance. The present findings support the possibility that severe cognitive impairment has an independent effect on survival.

Deriving a risk-adjustment model for pressure ulcer development using the Minimum Data Set

OBJECTIVE

To use the Minimum Data Set (MDS) to derive a risk-adjustment model for pressure ulcer development that may be used in assessing the quality of nursing home care.

DESIGN

Perspective observational study using MDS data from 1997.

SETTING

A large, for-profit, nursing home chain.

PARTICIPANTS

Our unit of analysis was 39,649 observations made on 14,607 nursing home residents who were without a stage 2 or larger pressure ulcer on an index assessment.

MEASUREMENTS

Pressure ulcer status was determined at an outcome assessment approximately 90 days after an index assessment. Potential predictors of pressure ulcer development were examined for bivariate associations, contributing to the development of a multivariate logistic regression model.

RESULTS

A stage 2 or larger pressure ulcer developed in 2.3% of the observations. Seventeen resident characteristics were found to be associated with pressure ulcer development. These included dependence in mobility and transferring, diabetes mellitus, peripheral vascular disease, urinary incontinence, lower body mass index, and end-stage disease. A risk-adjustment model based on these characteristics was well calibrated and able to discriminate among residents with different levels of risk for ulcer development (model c-statistic = 0.73).

CONCLUSION

A clinically credible risk-adjustment model with good performance properties can be developed using the MDS. This model may be useful in profiling nursing homes on their rate of pressure ulcer development.

Hospice enrollment and hospitalization of dying nursing home patients

PURPOSE

This study's purpose was to evaluate whether Medicare hospice care provided in nursing homes is associated with lower hospitalization rates.

SUBJECTS AND METHODS

This retrospective cohort study included nursing home residents in five states who enrolled in hospice between 1992 and 1996 (n = 9202), and who died before 1998. For each hospice patient, 3 nonhospice residents (2 in 106 instances) were chosen (n = 27,500). Medicare claims identified hospice enrollment and acute care hospitalizations.

RESULTS

Twenty-four percent of hospice and 44% of nonhospice residents were hospitalized in the last 30 days of life. Adjusting for confounders, hospice patients were less likely than nonhospice residents to be hospitalized (odds ratio 0.43; 95% confidence interval [CI]: 0.39 to 0.46). Considering all of nonhospice residents who died (n = 226,469), those in facilities with no hospice had a 47% hospitalization rate, whereas rates were 41% in facilities with low hospice use and 39% in facilities with moderate hospice use (5%+ of patients in hospice). Hospitalization was less likely for nonhospice residents in facilities with low hospice use (odds ratio 0.82; 95% CI: 0.80 to 0.84) and moderate hospice use (odds ratio 0.71; 95% CI: 0.69 to 0.74), compared with those in facilities with no hospice.

CONCLUSIONS

When integrated into the nursing home care processes, hospice care is associated with less hospitalization for Medicare hospice patients. Additionally, possibly through diffusion of palliative care philosophy and practices, nonhospice residents who died in nursing homes having a hospice presence had lower rates of end-of-life hospitalizations.

Mild cognitive impairment: clinical features and review of screening instruments

Clinical criteria to recognize subjects with cognitive impairment in the pre-dementia stage are becoming available. These are frail subjects, at risk of adverse outcomes, such as death, institutionalization, and functional and cognitive deterioration. Early identification of these subjects has a great importance in order to start rehabilitative or pharmacological interventions that could slow the progression of cognitive impairment, and the onset of disability. In this regard, cognitive screening tests might be helpful in different clinical settings (general practice, acute care, rehabilitation, and nursing home). We describe the most frequent clinical presentations of cognitive impairment in the pre-dementia stage, and review eleven screening tests to provide recommendations on which should be preferred in each setting.

Profiles of nursing home residents with multiple sclerosis using the minimum data set

This paper profiles nursing home residents with multiple sclerosis (MS) at the time of admission, including sociodemographic characteristics, health status measures, and treatments received. Admission assessments from the Minimum Data Set are used to create these profiles of residents with MS. There are 9,013 admission assessments in the MDS for residents with MS between June 22, 1998 and January 17, 2000 analyzed for this study. Residents with MS are distinctly younger at admission than most nursing home residents, averaging 57.98 years of age. Recently admitted residents with MS are more physically dependent than other nursing home residents and tend to have limited range of motion and loss of voluntary movement About one in three newly admitted residents with MS had some degree of impaired cognitive function. Over one third of residents with MS were depressed at admission, yet only 11.7% of recently admitted residents with MS were evaluated by a licensed mental health specialist This prompts concem about the psychosocial well-being of MS residents in nursing homes.

Clinical correlates and drug treatment of residents with stroke in long-term care

BACKGROUND AND PURPOSE

Stroke incidence increases with age, and stroke survivors often require nursing home placement. Characteristics of these residents and factors associated with the secondary drug prevention of stroke in nursing homes have yet to be explored.

METHODS

We used a population-based data set of all nursing home residents in 5 states (1992 to 1995). We identified 53 829 (20.4%) with a diagnosis of stroke on the Minimum Data Set assessment. We considered aspirin, dipyridamole, ticlopidine, or warfarin alone or in combination as secondary drug prevention. We used logistic regression modeling to identify independent predictors of drug treatment.

RESULTS

Sixty-seven percent of stroke survivors were not receiving drug therapy for stroke prevention. Among those treated, most received aspirin alone (16%) or warfarin alone (10%). Independent predictors of drug treatment included comorbid conditions (eg, hypertension, atrial fibrillation, depression, Alzheimer's disease, dementia, gastrointestinal bleeding, and peptic ulcer disease). Those over the age of 85 years were less likely to be treated than those 65 to 74 years of age (odds ratio [OR], 0.86; 95% confidence interval [CI], 0.82 to 0.91); black residents were less likely to be treated than whites (OR, 0.80; 95% CI, 0.75 to 0.85); and those with severe cognitive (OR, 0.63; 95% CI, 0.60 to 0.67) or physical impairment (OR, 0.69; 95% CI, 0.64 to 0.75) were also less likely to receive drug treatment.

CONCLUSIONS

Stroke is highly prevalent in long-term care. Despite the increased risk of subsequent stroke in the elderly, many are not being treated. The choice to treat or not to treat may be influenced by age, comorbidity, race/ethnicity, and cognitive or physical functioning.

Effect of nonsteroidal anti-inflammatory drug use on the rate of gastrointestinal hospitalizations among people living in long-term care

OBJECTIVES

Gastrointestinal (GI) complications are the most-common serious adverse reactions associated with nonsteroidal anti-inflammatory drugs (NSAIDs). We quantified the effect of specific NSAIDs on the rate of GI hospitalizations among older people living in long-term care.

DESIGN

Retrospective cohort study.

SETTING

All Medicare/Medicaid certified nursing homes in four states (Maine, Minnesota, New York, and South Dakota).

PARTICIPANTS

We identified 125,516 newly admitted residents from a database of all residents (1992-1996) of all Medicare/Medicaid certified nursing homes in four states. Using the federally mandated Minimum Data Set, which includes information on all drugs received (prescription and over-the-counter), we identified patients who received at least one prescription for aspirin (n = 19,101) or NSAIDs (n = 9,777). The control population consisted of all institutionalized persons who did not receive these drugs.

MEASUREMENTS

From Health Care Financing Administration inpatient claims, we identified the first hospitalization for GI perforation, ulcer, or hemorrhage that occurred during the year of follow up (ICD9-CM discharge codes: 531-534, 578). Cox proportional hazards models provided adjusted estimates of rate ratios.

RESULTS

NSAID exposure increased the GI-event-related hospitalization rate in both men (rate ratios (RR) = 2.64; 95% confidence interval (CI) = 1.17-5.99) and women (RR = 3.23; 95% CI = 1.85-5.65). The rate of GI hospitalizations for both men and women taking sulindac, naproxen, or indomethacin was higher than for nonusers. The risk of GI-event-related hospitalizations was greatest among women exposed to diflunisal (RR = 6.08; 95% CI = 2.27-16.26) or oxaprozin (RR = 6.03; 95% CI = 2.49-14.58).

CONCLUSIONS

Despite the high background rate of GI events, most NSAIDs increased the risk of GI hospitalization. Careful attention to choice of agent and dosing is needed in prescribing NSAIDs in this frail, older population.

Pharmacologic treatment of diabetes in long-term care

The majority of patients with diabetes are elderly, but little is known about their disease management. This study evaluates the prevalence and correlates of treatment of elderly diabetics residing in long-term care. We performed a retrospective, cross-sectional study of 75,829 elderly diabetics residing in nursing homes from 1992 to 1996. Nearly half (47%) of the residents received no antidiabetic medications. Independent predictors not receiving antidiabetic medications included age, race, impaired physical ability, and impaired cognitive function. Although the absence of resident's blood glucose or glycosylated hemoglobin (HbA1c) values prevents us from passing judgment about the adequacy of diabetic care, further research is needed to understand why some residents do not receive antidiabetic medications in the long-term care setting.

Pain in U.S. nursing homes: validating a pain scale for the minimum data set

PURPOSE

The aim of this study was to validate a pain scale for the Minimum Data Set (MDS) assessment instrument and examine prevalence of pain in major nursing home subpopulations, including type of admission and cognitive status.

DESIGN AND METHODS

This study considered validation of the MDS pain items and derivation of scale performed against the Visual Analogue Scale (VAS), using Automatic Interaction Detection. The derivation data describe 95 postacute care nursing home patients who are able to communicate. The scale is then used in retrospective analysis of 34,675 Michigan nursing home residents.

RESULTS

A four-group scale was highly predictive of VAS pain scores (variance explanation 56%) and therefore quite valid in detecting pain. In the prevalence sample, only 47% of postacute patients compared to 63% of postadmission patients reported no pain, and these percentages rose with increasing cognitive impairment.

IMPLICATIONS

Pain is prevalent in nursing home residents, especially in those with cognitive dysfunction, and often untreated.

Analyses of nursing home residents with HIV and dementia using the minimum data set

OBJECTIVE

The objective of this paper is to profile nursing home residents with HIV who also have dementia at the time of admission, using the Minimum Data Set (MDS). In addition, this paper compares HIV residents with dementia with other residents with HIV. These resident profiles contain sociodemographic characteristics, health status measures, treatments, and procedures.

STUDY SUBJECTS

There are 1,074 admission assessments for HIV residents with dementia and 4,040 admission assessments for other residents with HIV in the MDS between June 22, 1998 and January 17, 2000; these were analyzed for this study.

RESULTS

Other residents with HIV were twice as likely to be physically independent as HIV residents with dementia. Only 1 of 5 HIV residents with dementia was independent in cognitive skills for daily decision making compared with 3 of 5 other residents with HIV who were independent in these skills. Significantly greater percentages of HIV residents with dementia also had anemia, depression, schizophrenia, cognitive and memory problems, hepatitis, renal failure, and cancer than other residents with HIV.

CONCLUSIONS

These analyses demonstrate that HIV residents with dementia were significantly more likely to have other diseases, infections, and health care conditions than other residents with HIV.

Residential and nursing home care of elderly people with cognitive impairment: prevalence, mortality and costs

Cognitive impairment among residents has considerable resource implications for both individuals and those responsible for publicly funded care. Two linked surveys were carried out in England: (1) a longitudinal study followed 2500 admissions to publicly funded care up to 42 months after admission; and (2) a cross-sectional survey of 618 homes collected information about 11,900 residents. Information was collected about cognitive impairment using the Minimum Data Set Cognitive Performance Scale. Cognitive impairment was associated with source of funding and type of home. Although level of cognitive impairment has some effect, fees and costs were most influenced by type of home. At the same level of impairment, self-funded residents were more likely to be located in relatively low-cost settings than publicly funded residents. In independent homes fees were lower for publicly funded than for self-funded residents. Overall median length of stay of publicly funded admissions was 18 months. For the most part length of stay was not associated with level of cognitive impairment on admission. It is concluded that more information is needed about the effect of quality of care on people with cognitive impairment in different settings. If the same quality of care can be achieved in residential and nursing homes, the evidence would suggest that changes in placement policies could result in potential savings to the public purse.

State practice variations in the use of tube feeding for nursing home residents with severe cognitive impairment

OBJECTIVE

To describe the differences in prevalence of tube feeding among states and to examine possible factors that could explain practice patterns.

DESIGN

Analysis of random samples from an interstate data bank comprised of the Minimum Data Set (MDS), a standardized, federally mandated assessment instrument for nursing home residents.

SETTING

Nursing homes in four states participating in a federal demonstration project of case mix payment plus five others with existing MDS data systems.

PARTICIPANTS

Individuals 65 years of age and older (N = 57,029), who had very severe cognitive impairment, including total dependence in eating, and who resided in nursing homes during 1994, the most recent year for which uniform data were available.

MEASUREMENTS

State-by-state differences in prevalence of tube feeding, controlling for demographic and clinical variables.

RESULTS

The prevalence of tube feeding ranged from 7.5% in Maine to 40.1% in Mississippi. Each state had a significantly elevated prevalence of tube feeding compared with Maine, with odds ratios (ORs) ranging from 1.50 to 5.83, P < .001. Specific directives not to provide tube feeding (OR 0.41, P < .001), and white race (OR 0.45, P < .001) were strongly and negatively associated with tube feeding.

CONCLUSIONS

Wide regional variations exist in the use of tube feeding of nursing home residents with equivalent impairments. Sociodemographic factors could be important, but more study is needed to determine whether physician characteristics, such as race, attitudes, or knowledge, have an impact and to clarify medical standards for the use of tube feeding in this population.

The validity of the minimum data set in measuring the cognitive impairment of persons admitted to nursing homes

OBJECTIVES

This study examined the construct validity of two cognitive scales from the federally mandated Minimum Data Set (MDS) of the nursing home Resident Assessment Instrument.

DESIGN

A cross-sectional comparisons of the MDS measures, with scales provided by the resident, a proxy person, and nursing staff.

SETTING

Subjects residing in 59 nursing homes (NHs) in Maryland from 1992 to 1995.

PARTICIPANTS

Subjects were 1939 new admissions to NHs, aged 65 and older, with complete MDS information at admission.

MEASUREMENTS

Two MDS scales, the Cognitive Performance Scale (CPS) and the MDS Cognition Scale (MDS-COGS), were compared with the Mini-Mental State Examination (MMSE) and the staff rating on the Psychogeriatric Dependency Rating Scale (PGDRS) Orientation scale, as well as measures of functioning and functional decline.

RESULTS

The CPS and the MDS-COGS were highly correlated (r = 0.92). Both correlated moderately well with the MMSE (r = -0.65 and -0.68) and with staff's rating on the PGDRS Orientation scale (r = 0.63 and r = 0.66). Correlations with the MMSE (r < 0.70) are lower than previously reported (r > or = 0.80). The proportion of cognitively impaired residents in this NH admission cohort was higher using the MDS-COGS than the CPS (65% vs 57%), but both MDS scales produced lower proportions than the MMSE (70%) and higher proportions than the PGDRS (47%). The internal consistency of the CPS was better without the comatose item (alpha = 0.80 vs 0.70). The MDS-COGS had higher internal consistency (alpha = 0.85) and was simpler to compute.

CONCLUSIONS

This is the first study to examine the validity of the MDS in a large sample of residents and NHs in situations where the MDS was not completed by research-trained staff. Compared with other instruments, the MDS-COGS and the CPS had moderate and similar validity for assessing cognitive impairment. Differences in the scales could provide different estimates of impairment among persons admitted to nursing homes.

The prevalence of dementia in a statewide sample of new nursing home admissions aged 65 and older: diagnosis by expert panel. Epidemiology of Dementia in Nursing Homes Research Group

This study estimated the prevalence of dementia in 2,285 new admissions age 65+ to a statewide sample of 59 nursing homes in Maryland, 1992-1995. Dementia was ascertained according to DSM-III-R criteria by an expert panel of geriatric psychiatrists, neurologists, and a geriatrician using detailed information collected by trained lay evaluators from residents, family, staff, and medical records. Admissions to Maryland nursing homes are similar to admissions to nursing homes elsewhere in the United States. The prevalence of dementia was 48.2% (CI: 43.6-52.8) with an upper bound estimated at 54.5% (CI: 49.9-59.1). Prevalence is highest in facilities with <50 beds versus 200+ beds (65.5% vs 39.6%) and those in urban versus rural areas (50.0% vs 39.1%). Those who are non-White, married, and with fewer years of education are more likely to be demented. Prevalence is highest among those with 4+ physical impairments versus 0-1 (60.3% vs 27.7%) and lowest in those with 4+ comorbidities versus 0-1 (44.8% vs 52.0%). There was considerable overlap in the comorbid status of demented and nondemented admissions, and both groups contained members with only a few functional limitations. Results suggest that the level of medical supervision provided in nursing homes may not be required for some residents with dementia.

Tube feeding in nursing home residents with severe and irreversible cognitive impairment

OBJECTIVES

This study was undertaken to determine the degree to which selected demographic and clinical variables are associated with the use of feeding tubes in older nursing home residents with very severe and irreversible cognitive impairment.

DESIGN

Descriptive, cross-sectional, population-based study.

SETTING

Kansas nursing homes from January 1, 1994, through June 30, 1998.

PARTICIPANTS

A total of 4,997 nursing home residents with very severe and irreversible cognitive impairment comprised the study population. Subjects were identified using data in Minimum Data Set (MDS) reports. Those who were included in the study population were over the age of 65, had two consecutive Cognitive Performance Scale scores of 6, were without evidence of significant subsequent improvement, and were not comatose.

MEASUREMENTS

The MDS data on each resident were examined to determine subjects' age, ethnicity, gender, Medicaid eligibility, disease diagnoses, physical functioning, and oral/nutritional status, including feeding tube status. The MDS was also used to determine urban versus rural location of the nursing home. The association between the use of feeding tubes and selected demographic and clinical characteristics was then examined using bivariate and logistic regression tests.

RESULTS

Of the 4,997 residents in the study population, 577 (11.6%) had feeding tubes. In multivariate analysis, feeding tube use was found to be associated with swallowing problems (odds ratio (OR) 5.4, 95% confidence interval (CI) 4.3-6.8); urban location of nursing home (OR 2.9, 95% CI 2.3-3.5); non-white race (OR 2.7, 95% CI 1.9-3.6); stroke (OR 2.5, 95% CI 2.0-3.1); and absence of dementia (OR 2.5, 95% CI 2.0-3.1). Feeding tubes were also more weakly associated with age <86 years, male gender, dependency for all activities of daily living, and absence of a living will. Feeding tube use was not found to be associated with chewing problems, Medicaid status, or resuscitation status.

CONCLUSIONS

Clinical variables including swallowing problems, stroke, and absence of dementia were strongly associated with the use of feeding tubes in this cross-sectional, population-based study. In addition, urban location of nursing home and non-white race were significantly associated with feeding tubes. These findings suggest that feeding tube decisions are strongly influenced by nonclinical factors and invite further investigation.

Minimum data set for home care: a valid instrument to assess frail older people living in the community

BACKGROUND

Optimal care for frail elderly patients depends on comprehensive assessment. This is especially true in the complex setting of interdisciplinary home care programs. To facilitate comprehensive assessment, as well as to generate a useful, policy-relevant patient database, standardized, multidimensional, and validated instruments are very helpful.

OBJECTIVES

The aim of the present study was to demonstrate that the Minimum Data Set assessment instrument for Home Care (MDS-HC) can be used to detect functional and cognitive impairment as defined by analogous research instruments.

RESEARCH DESIGN

This was a cross-sectional correlation study.

SUBJECTS

We studied 95 patients admitted to home care services of the Health Care Agency of Bergamo (Italy).

MEASURES

The MDS-HC form was completed for all patients by well-trained nurses, independently of and with nurses blinded to the results from the research rating scales. The Barthel Activities of Daily Living (ADL) Index, the Instrumental Activities of Daily Living of Lawton (IADL), and the Mini Mental State Examination (MMSE) were considered the gold standard.

RESULTS

Agreement between the MDS-HC scales and the research rating scales was assessed with Pearson's correlation coefficient. This coefficient was 0.74 for MDS-ADL versus Barthel Index, 0.81 for MDS-IADL versus Lawton Index, and 0.81 for Cognitive Performance Scale versus MMSE, indicating an excellent agreement.

CONCLUSIONS

The MDS-HC scales, when performed by trained nurses using recommended protocols, provide a valid measure of function and cognitive status in frail home care patients. These findings point out the overall validity of the functional and clinical data contained in the MDS-HC assessment. Use of the MDS-HC gives the unique opportunity of setting up a database, a prerequisite for all epidemiological evidence-based medicine studies.

Estrogen use among nursing home residents with a diagnosis of Parkinson's disease

BACKGROUND

The role of estrogen in motor, cognitive, and behavioral functions in Parkinson's disease (PD) remains unclear.

OBJECTIVES/METHODS

To determine differences in functional, cognitive, and behavioral patterns between estrogen users and non-users, we performed an observational study on 10,145 elderly women with PD using the Systematic Assessment in Geriatric drug use via Epidemiology (SAGE) database. The SAGE database consists of the Minimum Data Set (MDS), data collected on a cross-section of over 400,000 nursing home (NH) residents in five US states. Using a cross-sectional study design, we evaluated the demographics, physical and cognitive function, and mortality rates of women with PD who received estrogen (n = 195) versus those who did not receive estrogen (n = 9950).

RESULTS

Independent of age, estrogen users were less cognitively impaired and more independent in their activities of daily living. Surprisingly, more estrogen users were depressed and more likely to be on an antidepressant than non-users. One-year death rates were comparable between estrogen users and non-users.

CONCLUSION

This study supports the growing number of recent data suggesting estrogen's potential beneficial effects on PD motor and cognitive functions.

Cognitive status and relocation stress: a test of the vulnerability hypothesis

PURPOSE

This study investigated whether cognitively impaired nursing home residents are at particular risk of experiencing harmful effects during a mass, intra-institutional, interbuilding relocation.

DESIGN AND METHODS

A pretest-post-test experimental-comparison group design was used. Data on cognitive status, functional capacity, psychosocial health status, physical health status, and mortality were abstracted from the Minimum Data Set Plus and were analyzed using continuous and discrete survival analyses, controlling for covariates as well as baseline status of outcome variables.

RESULTS

None of the Relocation x Cognitive Status interaction effects were significant. Relocation main effects indicated that movers in general were more likely than nonmovers to decline in physical health status. Evidence also emerged for a positive long-term effect of moving on psychosocial health status.

IMPLICATIONS

These findings suggest cognitively impaired residents are not at unusual risk of harmful effects as a consequence of mass, interbuilding transfer. Given the significant relocation main effects, though, caution must be taken in moving cognitively impaired residents, as it should be in moving any residents.

Stability of performance of activities of daily living using the MDS

The Minimum Data Set (MDS) requires assessment of performance of activities of daily living (ADLs) by newly admitted nursing home residents over all shifts for a 7-day period, for a total of 21 assessments. This study evaluated within-subject equivalence of multiple assessments of 42 residents' admission MDS ADL performance. Friedman two-way analysis of variance for ranks documented no significant within-subject differences among repeated measurements for all 13 MDS ADL variables. Thus, fewer than 21 assessments may accurately assess ADL performance.

The impact of legislation on psychotropic drug use in nursing homes: a cross-national perspective

OBJECTIVES

To quantify the impact of legislation on nursing home residents, psychotropic drug use, and the occurrence of falls in the US compared with five countries with no such regulation.

DESIGN

A retrospective cross-sectional study

SETTING

Nursing homes in five US states and selected nursing homes in Denmark, Iceland, Italy, Japan, and Sweden.

PARTICIPANTS

Residents in nursing homes in five US states and the aforementioned countries during 1993-1996.

MAIN OUTCOME MEASURES

Using data collected using the Minimum Data Set, logistic regression provided estimates of the legislative effects on the use of antipsychotics and antianxiety/hypnotics while simultaneously adjusting for potential confounders. The occurrence of falls was evaluated similarly.

RESULTS

Prevalence of antipsychotic and/or antianxiety/ hypnotic use varied substantially across countries. After adjustment for differences in age, gender, presence of psychiatric/neurologic conditions, and physical and cognitive functioning, residents in Denmark, Italy, and Sweden were at least twice as likely to receive these drugs (Denmark Odds Ratio (OR)=2.32; 95% Confidence Intervals (CI), 2.15-2.51; Italy OR=2.05; 95% CI, 1.78-2.34; Sweden OR=2.50; 95% CI, 2.16-2.90); in Iceland, the risk was increased to greater than 6 times (OR=6.54; 95% CI, 5.75-7.44) that of the US. Residents were less likely to fall in Italy, Iceland, and Japan compared with the US, despite more extensive use of psychotropic medication, whereas residents in Sweden and Denmark were more likely to fall.

CONCLUSIONS

Policy has had an impact on the prescribing of psychotropic medication in US nursing homes compared with other countries, but it is unclear if this is translated into better outcomes for residents.

Preserving residents' rights in long-term care settings: a values-based approach to restraint reduction

This article describes a knowledge transfer process that was developed by Catholic Health East (CHE), headquartered in Newtown Square, PA, and that focuses upon one indicator of care, physical restraint use, in the skilled nursing/long-term care setting. The values-based process focuses on preserving residents' rights and using comparative data sharing as the basis for identifying opportunities for improvement. Further, it builds upon a collaborative cyclical model employed by all the CHE System's freestanding and hospital-based long-term care facilities. The experiences of four of the system's facilities are described; each one demonstrates different aspects of implementing mission-oriented strategies to target restraint reduction.

Nursing home-to-nursing home transfers: prevalence, time pattern, and resident correlates

OBJECTIVES

To characterize the time pattern of nursing home-to-nursing home transfers and assess which resident characteristics are associated with transfers.

METHODS

Minimum Data Set assessments of all Maine and New York nursing home residents were obtained for 1994-1996. The hazard rate for nursing home transfers was estimated by nonparametric statistical techniques, censored at loss to follow-up. Comparisons of resident characteristics were made between those who transferred and those who stayed at their initial facility.

RESULTS

Residents of Maine nursing homes were considerably more likely to transfer than were New York residents. Transfer rates declined during the first 2 years after admission and remained stable thereafter. Correlates of transfers were similar across states. Residents who transferred were more likely to be male, to be married, to be younger, to have better cognitive and physical health, to have Medicare or private payment sources (vs. Medicaid), and to have pressure ulcers. Rural location did not affect the likelihood of transfer.

CONCLUSIONS

This study provides the most detailed information to date on the prevalence, timing, and correlates of nursing home transfers. These transitions occur most frequently early in the stay but continue at a lower rate even among long stayers. This information is useful for understanding lifetime dynamics of long-term-care utilization. Several barriers to mobility appear to be present (eg, less generous payment source, health limitations, and absence of a spouse). The higher transfer rates observed in Maine might imply that institutional or other factors limit the mobility of New York residents.

Cognitive ability and functional status

Significant confusion exists in the literature about functional status. Despite its importance, little attention has focused on developing and substantiating frameworks that detail the underpinnings of functional status, which has resulted in lack of agreement about its definition and dimensions. The purpose of this literature review was to examine the development of functional status and to describe the inclusion of its cognitive dimension. Cognition is one key dimension of functional status. One must 'know how' to perform to be successful in an activity. While cognitive capacity is generally considered in relation to functional status, the nature of the cognitive dimension is poorly described and poorly understood. Three databases were selected for review: Citations in Nursing and Allied Health (CINAHL), Psychology Literature (PsychLit), and the Medical data base known as MedLine. Key word searches identified thousands of sources. This analysis includes an extensive sampling of these sources from the 1960s through to 1998. The sources sorted into four primary categories and demonstrate a growing recognition of the cognitive dimension of functional status in the literature. Despite this recognition, the lack of conceptual clarity of both the term functional status and its cognitive dimension limits communication among disciplines and limits comparisons of functional status outcomes across studies. Functional status models are needed that include cognition as a core dimension. Population specific descriptions of the cognitive dimension should be guided by knowledge in the neurosciences.

Integrated health information systems based on the RAI/MDS series of instruments

There is a growing need for an integrated health information system to be used in community, institutional and hospital based settings. For example, changes in the structure, process and venues of service delivery mean that individuals with similar needs may be cared for in a variety of different settings. Moreover, as people make transitions from one sector of the healthcare system to another, there is a need for comparable information to ensure continuity of care and reduced assessment burden. The RAI/MDS series of assessment instruments comprise an integrated health information system because they have consistent terminology, common core items, and a common conceptual basis in a clinical approach that emphasizes the identification of functional problems.

Oxidative and nonoxidative benzodiazepines and the risk of femur fracture. The Systematic Assessment of Geriatric Drug Use Via Epidemiology Study Group

Benzodiazepine use is a well-identified risk factor for falls and the resulting femur fractures in elderly adults. Benzodiazepines not requiring hepatic biotransformation may be safer than agents undergoing oxidation because oxidative activity has been shown to decline with age. The association between the use of either oxidative or nonoxidative benzodiazepines and the risk of femur fracture among elderly adults living in nursing homes was studied. A nested case-control study was conducted using the Systematic Assessment of Geriatric drug use via Epidemiology (SAGE) database; the records of 9,752 patients hospitalized for incident femur fracture during the period 1992 to 1996 were extracted, matching by age, gender, state, and index date to the records of 38,564 control patients. Conditional logistic regression models were conducted to estimate the odds ratios (ORs) for femur fracture with adjustment for potential confounders. The adjusted OR for the overall use of benzodiazepines was 1.10 (95% confidence interval [CI], 0.98-1.20); the risk seemed of only slightly greater magnitude for exposure to nonoxidative agents (1.18; 95% CI, 1.03-1.36) than to oxidative benzodiazepines (1.08; 95% CI, 0.95-1.23). Among the latter, the effect was mainly accounted for by the use of agents with a long elimination half-life. A dose relationship was observed exclusively among users of long half-life oxidative benzodiazepines. The risk associated with the use of nonoxidative benzodiazepines showed no relationship to the age of the patients. In contrast, patients aged 85 years or older receiving oxidative benzodiazepines at high dosages or as needed had a two- to three-fold increased risk of femur fracture than did patients in the younger age group. Among older individuals, the use of benzodiazepines slightly increased the risk of femur fracture, mainly irrespective of the metabolic fate of the drug. Our results suggest that the use of nonoxidative benzodiazepines does not carry a lower risk for femur fracture than does the use of oxidative benzodiazepines. However, the latter agents may be associated with a somewhat higher risk of side effects among the oldest old, especially at higher dosages.

Effectiveness of feeding tubes in nursing home residents with swallowing disorders

BACKGROUND

Among nursing home residents who stop eating, a common decision for residents, caregivers, and families is the decision to begin tube feeding. This study examines the effectiveness of feeding tubes at reducing mortality among nursing home residents with swallowing disorders and feeding disabilities.

METHODS

Data from a version of the Minimum Data Set+ (MDS +) encompassing three different states from calendar years 1993 and 1994 were analyzed. Residents were included in the study if they were not totally dependent on staff for eating upon their first assessment but became totally dependent on staff for eating and had a swallowing disorder at some point during their nursing home stay. We used a proportional hazard regression to examine the relationship of feeding tubes with mortality after total eating dependence occurred.

RESULTS

Unadjusted Kaplan-Meier curves found that those with feeding tubes were less likely to die than comparable residents without feeding tubes (p < .001). Estimated survival at 1 year was 39% for those without feeding tubes and 50% for those with feeding tubes. The multivariate results indicated that feeding tubes were associated with a reduced risk of death (risk ratio, 0.71; 95% confidence interval, 0.59, 0.86).

CONCLUSIONS

This study provides evidence that tube feeding can be life-prolonging, even if the gain in life is not substantial. Such information can be useful to nursing home staff, residents, and families when trying to decide whether to place a feeding tube in a resident with swallowing disorders and eating disabilities.

Use of physical restraints and psychotropic medications in Alzheimer special care units in nursing homes

OBJECTIVES

This study analyzed the use of mechanical restraints and psychotropic medication in Alzheimer special care units (SCUs) in nursing homes.

METHODS

We analyzed 1993 data for more than 71,000 nursing home residents in 4 states, including more than 1,100 residents in 48 SCUs. The dependent variable in multinomial logistic regression was use of physical restraints or psychotropic medication. Models contained covariates representing facility and resident characteristics, and multivariate matching strategies were used to protect against selection bias.

RESULTS

Residents in SCUs did not differ from similar residents in traditional units in their likelihood of being physically restrained. Residents in SCUs were more likely to receive psychotropic medication.

CONCLUSIONS

With regard to the measures used in this research, the findings indicate that residents in the SCUs in the 4 study states did not receive quality of care superior to that provided to similar residents in traditional units. In fact, the results related to drug use raise the question of whether some may have received poorer care.

Prevalence, clinical characteristics, and pharmacologic treatment of Parkinson's disease in residents in long-term care facilities. SAGE Study Group

Despite the high prevalence of Parkinson's disease (PD) in the elderly, little information is available regarding the epidemiology of the disease in residents in long-term care facilities. Using a population-based database with over 470,000 residents (1992-1996) of all Medicare- or Medicaid-certified nursing homes of five states, we identified 24,402 residents with a diagnosis of PD. We examined data collected with the federally mandated Minimum Data Set, and sociodemographic, clinical, and treatment information. The prevalence of PD in nursing homes was 5.2%, with peak age-specific prevalence between ages 75 and 84 years. Seventy percent of patients had moderate to severe cognitive impairment, and over 80% had moderate to severe functional disability. Less than 10% had verbal and physical signs of grief and anxiety, and 80% exhibited poor psychosocial well-being, yet only 15% were actively treated for depression. Only 44% received antiparkinsonian drugs. Female gender, black race, age, level of cognitive impairment, and level of physical functioning were inversely related to the likelihood of receiving one of these drugs. When antipsychotic drugs were administered (15%), only 1% were atypical agents. Although PD is a relatively common diagnosis among nursing home residents, pharmacologic management of these individuals appears to be less than optimal.

Validity and responsiveness of the Minimum Data Set

OBJECTIVE

To determine the criterion validity and responsiveness to change over time of the Minimum Data Set (MDS).

DESIGN

Cross sectional analysis comparing prospectively collected research data with MDS data reported from nursing homes on identical subjects. Longitudinal follow-up of subjects allowed for calculation of responsiveness to change over time.

PARTICIPANTS

Subjects (n = 140) participating in epidemiological research on the natural history of Alzheimer's disease in the University of Washington Group Health Cooperative Alzheimer's Disease Patient Registry (ADPR) who entered nursing homes in Washington State from January 1990 through March 1996.

MAIN OUTCOME MEASUREMENTS

Spearman's correlation coefficients to compare MDS cognitive performance scale scores with Mini-Mental State Examinations (MMSE), MDS behavior domain scores with ADPR Physician Behavior checklist scores, and MDS activities of daily living (ADL) functioning scores with Dementia Rating Scale scores for ADLs. Partial correlations were used to control for the number of days between MDS and ADPR assessments, age, and function in the other two MDS ratings of ADL, cognition, or behavior. We determined responsiveness by using the mean change in an effect size (ES) calculation for each domain of interest.

RESULTS

MDS measures in all three domains were correlated modestly to the analogous ADPR research instruments, with correlation coefficients 0.45 for cognition, 0.50 for behavior, and 0.59 for ADL functioning. Controlling for age, time between ADPR and MDS assessments, and the MDS ratings of the other two MDS domains did not improve the correlations significantly. In a subgroup of 60 subjects followed for an average of 636 days, the Cognitive performance scale of the MDS had a slightly larger effect size (ES = 0.60) than the Folstein Mini-Mental Status Exam (ES = 0.39) used by the ADPR. However, the Dementia Rating Scale (ES = 0.77) used by the ADPR researchers reflected more change over time than the ADL domain of the MDS (ES = 0.02). The MDS behavior domain (ES = 0.058) was comparable to the research behavior checklist (ES = 0.065).

CONCLUSIONS

These data demonstrate reasonable criterion validity of the MDS and the MMSE, ADL, and behavior rating scales and suggest that the MDS data is of adequate validity for research purposes in these areas. The MDS was less able to capture dementia-related change in ADLs in this population of patients with dementia even though the same nursing home staff completing the MDS often supplied the information for completing the research scales. As a result, the MDS may be limited as an outcome assessment instrument.

A model for integrated home care of frail older patients: the Silver Network project. SILVERNET-HC Study Group

Home care programs for the treatment of frail elderly have been developed in many countries around the world. In the Silver Network project all services are provided in an integrated fashion by one "single entry" center, differently from the traditional fee-for-service or not integrated systems. The delivery of health and social services for frail elderly individuals are integrated and coordinated by a case manager who uses a "second generation" assessment instrument, the Minimum Data Set for Home Care (MDS-HC). We describe the principal clinical and functional characteristics of nearly 1300 patients admitted between 1997 and 1998 to such an integrated home care program in eleven Italian Health Agencies. The database, derived from the serial MDS-HC assessments of each patient, provides a unique opportunity to delineate the different criteria for eligibility for home care, and compare the selected populations of the participating Health Agencies.

Correlates and management of nonmalignant pain in the nursing home. SAGE Study Group. Systematic Assessment of Geriatric drug use via Epidemiology

OBJECTIVE

Nonmalignant pain is a common problem among older people. The prevalence of pain in the nursing home is not well studied. We looked at the association between nonmalignant pain, psychological and functional health, and the practice patterns for pain management in the nursing home.

DESIGN

A cross-sectional study.

SETTING

Nursing Home in four US states.

PARTICIPANTS

A total of 49,971 nursing home residents from 1992 to 1995.

MEASUREMENTS

We used the SAGE database (Systematic Assessment of Geriatric drug use via Epidemiology), which linked information from the Minimum Data Set and nursing home drug utilization data. The MDS items measured included pain, activities of daily living (ADL) function, mood, and time involved in activities. The use of analgesics, anxiolytics, and antidepressants was also documented.

RESULTS

Daily pain was reported in 26% of nursing home residents. The prevalence was lower among men, persons more than age 85, and racial minorities. Persons suffering pain daily were more likely to have severe ADL impairment, odds ratio (OR) (2.47 (95% CI, 2.34-2.60)), more depressive signs and symptoms (OR 1.66 (95% CI, 1.57-1.75)), and less frequent involvement in activities (OR 1.35 (95% CI, 1.29-1.40)). Approximately 25% of persons with daily pain received no analgesics. Residents who were more than 85 years old (OR 1.15 (95% CI 1.02-1.28)), cognitively impaired, (OR 1.44 (95% CI, 1.29-1.61)), of male gender (OR 1.17 (95% CI, 1.06-1.29)), or a racial minority (OR 1.69 (95% CI, 1.40-2.05) and OR 1.56 (95% CI, 0.70-1.04) for blacks and Hispanics, respectively) were at greater risk of not receiving analgesics. Approximately 50% of those in pain used physical and occupational therapies, which was more than two times higher (OR 2.44 (95% CI, 2.34-2.54)), than use for those not in pain.

CONCLUSIONS

Daily nonmalignant pain is prevalent among nursing home residents and is often associated with impairments in ADL, mood, and decreased activity involvement. Even when pain was recognized, men, racial minorities, and cognitively impaired residents were at increased risk for undertreatment. More education and research is necessary to improve the recognition and management of pain in the nursing home, remembering that attention should be paid to populations at increased risk for underrecognition and undertreatment.

Examining the efficiency of home care

This article focuses on the "efficiency" or cost-effectiveness of home care. Because home care encompasses a range of services targeted to many populations, it is necessary to take cognizance of case mix and clarify its goals to assess effectiveness. Goals for home care can be thought of as meeting and/or compensating for client dependency needs or making a difference in the client's clinical trajectory. The latter implies comparing actual to expected outcomes, where outcomes can cover a wide range of domains addressing quality of care and quality of life. Inferring the effect of treatment (i.e., home care) on various outcomes will likely rely heavily on epidemiological techniques that, in turn, rely on sophisticated statistical techniques. Problems measuring the costs of care include how to handle the costs of informal care and deciding whose costs should be of primary concern. Better data about the costs, and experimentation with different forms of caregiving, need to be pursued.

Predictors of mortality in patients with Alzheimer's disease living in nursing homes

OBJECTIVES

To identify factors associated with mortality in patients with Alzheimer's disease, and to evaluate whether these factors vary according to severity of cognitive impairment.

METHODS

Data were from the SAGE database which includes information on all residents admitted between 1992 and 1995 to all Medicare/ Medicaid certified nursing homes of five US states. We conducted a longitudinal follow up study (median 23 months) on 9264 patients aged 65 years and above with a diagnosis of Alzheimer's disease. Patient data including demographic characteristics, dementia severity, comorbidity, and other clinical and treatment variables were collected with the Minimum Data Set. Information on death was derived through linkage to Medicare files. Baseline characteristics were used to predict survival in univariate and multivariate Cox proportional hazard models.

RESULTS

Overall mortality rate was 50%, with a first year rate of 25.7%. Increased age (risk ratio (RR) 1. 83; 95% confidence interval (95% CI) 1.65-2.03, for patients 85+ years), male sex (RR 1.81; 95% CI 1.70-1.94), limitation in physical function (RR 1.45; 95% CI 1.27-1.66), a condition of malnutrition (RR 1.31; 95%CI 1.23-1.39), the presence of pressure ulcers (RR 1.24; 95% CI 1.13-1.36), a diagnosis of diabetes mellitus (RR 1.32; 95% CI 1.21-1.43), and of cardiovascular diseases (RR 1.22; 95% CI 1. 14-1.30) were independent predictors of death, regardless of the severity of baseline dementia. Sensory problems (hearing and vision) and urinary incontinence were associated with increased mortality only among patients with less severe dementia. The presence of disruptive behaviour, aphasia, and a diagnosis of Parkinson's disease were not related to survival. African-Americans and other minority groups were less likely to die relative to white people.

CONCLUSIONS

Age, sex, functional limitation, and malnutrition seem to be the strongest predictors of death for patients with Alzheimer's disease in nursing homes. Altogether, severity of dementia has no influence on survival, yet the predictive role of certain variables depends on the degree of impairment. Minority groups have a reduced risk of death relative to white people.

The Minimum Data Set 2.0: a functional assessment to predict mortality in nursing home residents

Measures of functional assessment, such as the Karnofsky Scale, the Modified ADL Scale, and the Descriptive Scale, have been used to predict appropriateness for hospice care. A tool is needed to assess functional status across all treatment settings, including acute care, long-term care, and hospice. The objective of this paper is to determine whether the Minimum Data Set, when utilized in conjunction with physical assessment tools to determine prognosis, is accurate in predicting short-term mortality in nursing home residents. The paper has been designed as a retrospective study of residents in 24 Minnesota nursing homes who were referred to a hospice program. The study included 199 patients from 30 to 107 years of age. Functional variables, as triggered by the Minimum Data Set, have a direct correlation to patient mortality within three months of the documented observation of the triggered variable, and are the main outcome measure. Of a total of 199 patients, 147 patients (74 percent) died within 15 days of a documented significant decline in the Minimum Data Set in areas of cognitive function, communication, activities of daily living, incontinence, and nutrition. Age, gender, diagnosis, and significant medical data received from the nursing home staff at the time of referral to hospice were applied to the Karnofsky Scale, the Modified ADL Scale, the Descriptive Scale, and the Minimum Data Set to determine if a resident assessment protocol (RAP) would be triggered by these data. The data were then analyzed to determine whether there existed a correlation between a significant change, as documented on the Minimum Data Set, and subsequent death of the patient. If there existed a correlation, the data were further studied to determine consistency in the categories of change that might demonstrate predictors of short-term mortality in nursing home residents. A decline in functional status, as documented on the Minimum Data Set 2.0 in the areas of cognitive functioning, communication, activities of daily living, incontinence, and nutrition, are strong predictors of short-term mortality in nursing home residents, independent of age, gender, and diagnosis.

Antiischemic therapy in patients with coronary heart disease living in long-term care. Systematic Assessment of Geriatric Drug Use by Epidemiology (SAGE) Group

We evaluated antiischemic therapy in elderly nursing home residents with a diagnosis of coronary heart disease (CHD) using a population-based data base with over 300,000 residents (1992-1995) of all Medicare/Medicaid-certified nursing homes of five states. We identified 72,263 patients age 65 years or older with a diagnosis of CHD. We examined data collected with the federally mandated Minimum Data Set, drug information, and Medicare hospital claims. Antiischemics were defined as beta-adrenergic blockers, long-term nitrates, and calcium channel blockers. We determined factors associated with use of the drugs by logistic regression. Antiischemic therapy was inversely related to age and cognitive and physical functioning, but positively associated with recent hospitalization and concomitant cardiovascular diseases. beta-Adrenergic blockers were least likely to be administered regardless of age, gender, or cognitive or physical function. We conclude that antiischemic therapy in nursing home residents may not be optimal.

Evaluation of Simulated Presence: a personalized approach to enhance well-being in persons with Alzheimer's disease

OBJECTIVE

To evaluate the efficacy of Simulated Presence, a personalized approach to enhance well-being among nursing home residents with Alzheimer's disease and related dementia's (ADRD).

DESIGN

Latin-Square, double blinded, 3-factor design with restrictive randomization of three treatments (the study intervention, a placebo audio tape of a person reading the newspaper, and usual care). The three factors were treatment, time, and facility type.

SETTING

Nine nursing homes in Eastern Massachusetts and Southern New Hampshire.

PARTICIPANTS

Fifty-four subjects with documented ADRD who were aged 50 years or older, medically stable, had resided in their current nursing home for at least 3 months, and who had no planned discharge. All subjects had a history of agitated or withdrawn behaviors.

INTERVENTION

The purpose of Simulated Presence is to provide a personalized intervention for persons with moderate to severe cognitive impairment. Through a unique testing process, some of the best loved memories of the ADRD person's lifetime are identified and then those memories are introduced to the patient in the format of a telephone conversation using a continuous play audio tape system. The intervention may be used for extended periods of time because each repetition is viewed as a fresh, live telephone call as a result of the short-term memory deficit of the person with ADRD.

MEASUREMENTS

Direct observations of outcomes included using a newly developed scale, the Scale for the Observation of Agitation in Persons with Dementia, an agitation visual analog scale, the Positive Affect Rating Scale (mood and "interest"), a withdrawal visual analog scale, and facial diagrams of mood. Reported measures included daily staff observation logs of responses to interventions offered, and weekly staff surveys using the short-form Cohen-Mansfield Agitation Inventory and the Multidimensional Observation Scale for Elderly Subjects (mood and "interest"). Severity of dementia was assessed by the Mini-Mental State Exam, the Test for Severe Impairment, the Bedford Alzheimer's Nursing Scale, and the ADL Self-Performance Scale.

RESULTS

Chi-square analysis of direct observations, using facial diagrams, revealed that Simulated Presence was equivalent to usual care (P = .141) and superior to placebo for producing a happy facial expression (P = .001). A positive effect was also documented in nursing staff observation logs using Analysis of Variance techniques (ANOVA) for subjects during Simulated Presence phases compared with the placebo phases (P < .001) and usual care phases (P < .001). According to ANOVA analyses of "interest" from weekly surveys, Simulated Presence was superior to both usual care (P = .001) and placebo (P = .008). We were unable to find evidence of significant differences (P < .05) among interventions for other direct observations and weekly reports of overall agitation or mood aspects of withdrawal. Subjects accepted the intervention most of the time, except for five subjects who refused it more than 50% of the time.

CONCLUSION

This study provided evidence that Simulated Presence can be effective in enhancing well-being and decreasing problem behaviors in the nursing home setting as a substitute for or complement to usual care.

Is drug use by the elderly with cognitive impairment influenced by type of dementia?

Patterns of drug use among the elderly vary greatly depending on level of cognitive function, yet no systematic evaluation of drug use by type of dementia has been performed. We compared patterns of drug use among patients with Alzheimer's disease (AD) and vascular dementia (VaD) to examine their relation to cognitive impairment. We used a population-based data set with over 350,000 residents admitted between 1992 and 1995 to all Medicare-Medicaid-certified nursing homes in five states. After excluding patients with a history of mental disorders or retardation, we identified 23,073 patients age 65 years and over with a diagnosis of AD and 76,087 with VaD. We examined over 350 resident data items (demographic, diagnostic, clinical, treatment) collected with the federally mandated Minimum Data Set, drug data (brand name, dosage, route and frequency of administration for all drugs), and Medicare hospital claims. Cognitive status was measured with a 7-point cognitive performance scale. Estimates of drug use were adjusted for age, gender, race, and prevalence of respective disease. Patients with AD were younger and had more severe cognitive impairment than those with VaD. The latter had more comorbid clinical conditions (3.1 +/- 1.9 vs 2.3 +/- 1.7 for patients with AD) and received a greater number of total drugs (6.1 +/- 4.6 vs 5.3 +/- 4.3). Overall use of cardiovascular, anti-Parkinson, pulmonary, antineoplastic, and nutritional agents was less frequent among patients with AD than those with VaD. Results were consistent across different levels of cognitive impairment. Thus, patients with AD have fewer associated diseases and appear to be less intensively medically treated.

Acute confusion indicators: risk factors and prevalence using MDS data

Long-term care (LTC) Minimum Data Set (MDS) data from a Midwestern state were analyzed to validate whether components of a conceptual model developed from findings in acute care identified acute confusion risk variables in LTC. The prevalence of probable acute confusion in this sample was 13.98% (n = 324). Using a cross-sectional design, both univariate and unconditional stepwise logistic regression analyses were accomplished with presence or absence of probable acute confusion as the outcome variable (N = 2,318). Variables significantly related to acute confusion by univariate analysis were included in the logistic regression analysis. Inadequate fluid intake was the first variable to enter the stepwise equation and was highly significant (OR 3.40, 95% CI 2.99-3.81, p < .0001). Other significant variables included a diagnosis of dementia or a fall in the last 30 days. Implications for nursing practice, education and research are discussed.

Facility characteristics associated with hospitalization of nursing home residents: results of a national study

OBJECTIVES

To test the effect of facility characteristics on the probability of hospitalization of nursing home residents, controlling for resident characteristics and the competing risk of death.

RESEARCH DESIGN

Study data were derived from the evaluation of the implementation of the Resident Assessment Instrument, the Minimum Data Set (MDS) in 1993. The data consisted of 2080 residents in 253 NHs as well as the annual On-Line Survey Certification of Automated Records (OSCAR).

MEASURES

Multinomial logistic regression was used to determine the effects of selected resident and facility characteristics on hospitalization or death within 6 months of baseline, adjusting for the complex sampling design (using SUDAAN).

RESULTS

By controlling for resident demographics, advance directives, diagnoses, selected clinical signs, and type of payer, we found that homes with special care units, more physicians (above the median 0.08 FTE physicians on staff or contract), and any physician extenders (nurse practitioners or physician assistants) were less likely to hospitalize their residents. Homes in which over 3.6% of the residents received respiratory treatment were more likely to hospitalize their residents.

CONCLUSIONS

Findings suggest that Medicare HMOs should consider the capacity of nursing facilities, especially in terms of medical care capacity and clinical resources, to limit hospital admissions.

Staff views on the Resident Assessment Instrument, RAI/MDS, in nursing homes, and the use of the Cognitive Performance Scale, CPS, in different levels of care in Stockholm, Sweden

Multidimensional functional assessment is the basis of individualized care. It is especially important in the care of elderly, with the complexity of symptomatology and often with cognitive impairment present. An assessment instrument for elderly persons, used in this study, is the Resident Assessment Instrument/Minimum Data Set (RAI/MDS) and its incorporated MDS Cognitive Performance Scale (CPS). The purposes of the study were to demonstrate the cognitive performance in elderly persons in different levels of care by using the CPS and to elicit the views of staff on use of the RAI/MDS. Cognitive impairment was found in 1276 elderly persons in six levels of care studied, an important factor to consider when organizing care of elderly. An intervention study was carried out for 1 year in three nursing home wards, with training and supervision in implementation of the RAI/MDS including individualized and documented care. Part of a questionnaire was used to evaluate staff (n = 50) views on using the instrument. A majority of the staff thought that the RAI/MDS could contribute to the improvement of quality of care, documentation in nursing records, and in co-operation and engagement. Further research is necessary to elicit more knowledge on the usefulness and benefits of the instrument.

A practical approach to identifying mortality-related factors in established long-term care residents

OBJECTIVE

Determining prognosis is an important part of medical planning for long-term care residents. Clarifying the resident characteristics associated with increased mortality has received little attention from investigators, and many approaches that have been suggested are unsuitable for widespread use. Using a readily available database, we sought to determine factors associated with 1-year mortality in established long-term care residents.

DESIGN

A retrospective cohort study.

SETTING

A 725-bed long-term care facility.

MEASUREMENTS

We examined Minimum Data Set (MDS) information on 780 residents from April 1994 through August 1997. The association between death and 65 resident factors, covering a broad array of physical, functional, medical, and psychosocial measures, was examined initially in bivariate proportional hazards models. Putative factors with P values < .10 in bivariate analysis were considered in the multivariate analysis. Using these factors, we employed a forward step-wise multivariate proportional hazards regression method to select the set of factors associated independently with mortality at a P value < .05. A mortality score was developed by assigning points to each factor based on the risk ratio in the multivariate proportional hazards model. The performance characteristics of the model were examined using logistic regression.

RESULTS

Forty-four of the 65 factors examined were associated with 1-year mortality in bivariate proportional hazards analysis. Eight of these 44 factors were associated with 1-year mortality in the multivariate proportional hazards regression. These factors were functional impairment, weight loss, shortness of breath, male gender, low body mass index, swallowing problems, congestive heart failure, and advanced age. A higher mortality score was associated with a higher death rate in the subsequent year. The model demonstrated good performance with an area under the ROC curve of 0.77.

CONCLUSIONS

Using a widely available database that requires no additional medical testing or staff training, a useful model for identifying factors associated with 1-year mortality in established long-term care residents can be developed. Widespread use of such a practical approach to assess mortality risk could be of benefit to patients, their families, and physicians for informing care plan decisions.
