Depression and its relationship to function and medical status, by dementia status, in nursing home admissions.

OBJECTIVE: To determine rates of depression by dementia status in a statewide sample of nursing home admissions, and associations with medical comorbidity and physical functioning. METHODS: Trained interviewers obtained information from nursing home residents, staff, significant others, and medical records. RESULTS: A total of 22.3% were classified depressed in the nondemented status and 23.6% in the demented status. Depression status was significantly associated with more physical dependencies regardless of dementia status. In the nondemented, there was also a significant positive association with number of comorbidities. One interaction, dementia with comorbidity at the highest levels of comorbidity, was significant in looking at association with depression. CONCLUSION: There is significant depressive symptomatology in nursing home admissions, which is also associated with difficulty in physical function and with the number of medical comorbidities in the nondemented. Application of the two measures used in this study represents a strategy to assess depression in all nursing home residents.

Mortality and adverse health events in newly admitted nursing home residents with and without dementia.

OBJECTIVES: To evaluate the association between dementia and mortality, adverse health events, and discharge disposition of newly admitted nursing home residents. It was hypothesized that residents with dementia would die at a higher rate and develop more adverse health events (e.g., infections, fevers, pressure ulcers, falls) than residents without dementia because of communication and self-care difficulties. DESIGN: An expert clinician panel diagnosed an admission cohort from a stratified random sample of 59 Maryland nursing homes, between 1992 and 1995. The cohort was followed for up to 2 years or until discharge. SETTING: Fifty-nine Maryland nursing homes. PARTICIPANTS: Two thousand one hundred fifty-three newly admitted residents aged 65 and older not having resided in a nursing home for 8 or more days in the previous year. MEASUREMENTS: Mortality, infection, fever, pressure ulcers, fractures, and discharge home. RESULTS: Residents with dementia had significantly lower overall rates of infection (relative risk (RR)=0.77, 95% confidence interval (CI)=0.70-0.85) and mortality (RR=0.61, 95% CI=0.53-0.71) than those without dementia, whereas rates of fever, pressure ulcers, and fractures were similar for the two groups. These results persisted when rates were adjusted for demographic characteristics, comorbid conditions, and functional status. During the first 90 days of the nursing home stay, residents with dementia had significantly lower rates of mortality if not admitted for rehabilitative care under a Medicare qualifying stay (RR=0.25, 95% CI=0.14-0.45), were less often discharged home (RR=0.33, 95% CI=0.28-0.38), and tended to have lower fever rates (RR=0.78, 95% CI=0.63-0.96) than residents without dementia. CONCLUSION: Newly admitted nursing home residents with dementia have a profile of health events that is distinct from that of residents without dementia, indicating that the two groups have different long-term care needs. Results suggest that further investigation of whether residents with dementia can be well managed in alternative residential settings would be valuable.

Racial variations in causes of vision loss in nursing homes: The Salisbury Eye Evaluation in Nursing Home Groups (SEEING) Study.

OBJECTIVE: To determine the prevalence and causes of low vision in a large sample of nursing home residents. METHODS: Twenty-eight nursing homes on the Eastern Shore of Maryland and Delaware were enrolled in a clinical trial to assess the impact of vision restoration/rehabilitation on nursing home residents. Visual acuity was measured using both recognition charts and preferential looking techniques. An ophthalmologist examined all residents with visual acuity worse than 20/40 in the better-seeing eye and determined the primary cause for decreased vision. Results are reported for the better-seeing eye. RESULTS: Of 2544 eligible residents, 1591 (63%) participated, but 286 residents were unable to respond to visual acuity testing. Of the remaining 1307 residents, 496 (37%) had best-corrected visual acuity worse than 20/40 in the better-seeing eye. Causes were ascribed for 412 subjects. Rates of low vision were similar between African American subjects and white subjects (39% and 38%, respectively; age-adjusted P =.18). Cataract was the leading cause of low vision, responsible for 37% of low vision among white subjects and 54% of low vision among African American subjects. Macular degeneration was responsible for 29% of low vision among white subjects but only 7% among African American subjects. Glaucoma caused low vision in 4% of white subjects and 10% of African American subjects. Refractive error was not a frequent cause of low vision in nursing home residents. CONCLUSIONS: Low vision is highly prevalent among nursing home residents, with 37% having visual acuity worse than 20/40 in the better-seeing eye. Differences in causes of low vision between African American subjects and white subjects were noted, with African American subjects more likely to have vision loss on the basis of cataract, a readily treated condition. Appropriate interventions for nursing home residents, who face significant obstacles in accessing eye care services, have the potential to improve the quality of life of this at-risk older population.

Pressure ulcers and the transition to long-term care.

OBJECTIVE: To estimate the prevalence of pressure ulcers among newly admitted residents of long-term-care facilities and to determine whether patients admitted from hospitals had a higher prevalence than those admitted from home or other settings. DESIGN: Prospective cohort study conducted between 1992 and 1995. SETTING: 59 long-term-care facilities in Maryland. PARTICIPANTS: 2015 residents aged 65 years and older newly admitted to participating long-term-care facilities. MAIN OUTCOME MEASURE: Stage II, III, or IV pressure ulcer, first mentioned in the long-term-care facility's chart within 2 days of admission. MAIN RESULTS: Of the 2015 residents studied, 208 (10.3%) had 1 or more pressure ulcers on admission to a long-term-care facility. The proportion of patients with 1 or more pressure ulcers was 11.9% among those admitted from a hospital and 4.7% among those not admitted from a hospital (P<.001). In multivariable analysis, admission from a hospital was significantly associated with pressure ulcer prevalence on admission (odds ratio, 2.2; 95% confidence interval, 1.3-3.7). A lower prevalence of pressure ulcers on admission was significantly associated with being white; a higher prevalence was associated with being chairbound or bedridden, being underweight, and having fecal incontinence. CONCLUSION: Admission to a long-term-care facility from a hospital is an important marker for higher pressure ulcer risk. The identification of pressure ulcer risk factors is essential to the implementation of prevention activities, ensuring that appropriate interventions are targeted to the residents who are most likely to benefit.

A randomized trial of visual impairment interventions for nursing home residents: study design, baseline characteristics and visual loss.

INTRODUCTION: Visual impairment among nursing home residents is higher than in community-dwelling elderly. The provision of eye care services may be beneficial to nursing home patients. Our project, a randomized trial of vision restoration and rehabilitation in nursing home residents, compares usual care to targeted interventions. In this paper, we present the baseline characteristics of our sample within the nursing homes. METHODS: Twenty-eight nursing homes on Maryland's Eastern Shore were matched in pairs by size and payment type. Each pair was randomized to usual care or targeted intervention. Habitual and best-corrected acuity was attempted, using standard letter symbol/charts and grating acuity charts. Visual impairment was vision in the better eye <20/40 on letter and/or grating acuity. The MiniMental State Examination (MMSE) was used to determine cognitive impairment. RESULTS: Of those participants eligible to be screened, 40% had severe cognitive impairment (MMSE score 0-9). No measure of acuity could be ascertained on 18% of eligibles. Among the 1305 persons with acuity data, 38% had presenting vision worse than 20/40. After refractive correction, 29% had visual impairment. There was no difference by race or gender in those with visual impairment, although they were older, compared to those without visual loss. CONCLUSIONS: The nursing home residents had high rates of both cognitive impairment and visual impairment, creating a challenging environment for visual intervention. By improving access to eye care within the context of the clinical trial, and changing either the magnitude of visual loss or the resultant impact on function, we hope to demonstrate a change in the quality of life for nursing home residents.

Identifying dementia in high-risk community samples: the memory and medical care study.

The Memory and Medical Care Study (MMCS) is a community-based, longitudinal study of elders at risk for dementia. This paper describes the study methods for identifying subjects with dementia or mild cognitive impairment (MCI) and the validation of these methods. The MMCS cohort was established by identifying subjects at risk for dementia in three previous studies of randomly ascertained samples. Neuropsychologic test score criteria were established to identify MMCS subjects with dementia or MCI. These criteria were validated using a fourth community-based sample of at-risk elders in which dementia was identified by a clinical adjudication panel. Of the 498 MMCS subjects, 70% had dementia and 27% had MCI by the MMCS criteria. In the validation sample, the MMCS dementia classification method was in agreement with the clinical adjudication panel for 81% of cases (kappa = 0.62, 95% confidence interval = 0.45-0.78). The methods used in the MMCS are efficient and reasonably valid for establishing a cohort of subjects to investigate how dementia is assessed, diagnosed, and treated in the community.

A Longitudinal Study of Participation in Nursing Home Activity Programs.

The authors evaluated participation in activity programs in a prospective study of 198 new nursing home admissions. Both on admission and after 1 year, approximately 50% of patients were not participating in activities. Nonparticipation was associated with greater cognitive and functional impairment and the use of restraints and neuroleptics. Over the year, activity status changed for approximately 50% of patients in relation to these factors. These findings indicate current limitations in nursing home activity programs and suggest that participation is a dynamic process influenced by identifiable clinical variables. Revision of activity programs is necessary to meet OBRA regulations to improve the quality of patients' lives.

Underutilization of Physical and Mental Health Services Prior to Nursing Home Admission.

The authors interviewed the families of 420 nursing home admissions to examine the relationship between patients' need for nursing and mental health services and their use of these services prior to nursing home placement. Although the majority of demented and nondemented patients needed help with activities of daily living, and many needed help with behavioral disorders, fewer than one-third of the families of these patients used community nursing and mental health services for these problems. Increased awareness of the potential value of and improved access to these services may postpone or prevent nursing home placement.
