Comprehensive clinical assessment in community setting: Applicability of the MDS-HC

OBJECTIVE: To describe the results of an international trial of the home care version of the MDS assessment and problem identification system (the MDS‐HC), including reliability estimates, a comparison of MDS‐HC reliabilities with reliabilities of the same items in the MDS 2.0 nursing home assessment instrument, and an examination of the types of problems found in home care clients using the MDS‐HC.

Impact near the hip dominates fracture risk in elderly nursing home residents who fall

SummaryHip fractures among the elderly are a significant and rapidly growing public health problem. The prevailing view is that most hip fractures are the consequence of age-related bone loss or osteoporosis. However, because over 90% of hip fractures are the result of falls, we have undertaken a falls surveillance study to determine if factors related to the mechanics of falling are associated with increased risk of hip fracture. Case subjects with hip fracture and control subjects without hip fracture were sampled from falls recorded at the Hebrew Rehabilitation Center for Aged, a chronic care facility. Fall information was obtained by interview of the subject and witnesses if the fall was witnessed. Data were analyzed by multiple logistic regression. Increased risk of hip fracture from a fall was associated with impacting on the hip or side of the leg and potential energy associated with the fall. Quetelet, or body mass index, was inversely related to fracture risk. The adjusted odds ratio of hip fracture for a fall involving impact on the hip region was 21.7 (95% confidence interval, 8.2–58). The potential energy associated with these falls was an order of magnitude greater than the average energy required to fracture elderly, cadaveric, proximal femurs in earlier in vitro experiments. We conclude, therefore, that a fall from standing height should no longer be considered minimal trauma but rather trauma of sufficient magnitude to pose a high risk of hip fracture if impact occurs on the hip and if energy-absorbing processes are inadequate. These new findings suggest that fall mechanics play an important role in the etiology of hip fracture among the elderly.

Ten-Year Effects of the Advanced Cognitive Training for Independent and Vital Elderly Cognitive Training Trial on Cognition and Everyday Functioning in Older Adults

To determine the effects of cognitive training on cognitive abilities and everyday function over 10 years.

A commitment to change: revision of HCFA's RAI.

OBJECTIVE: To describe the reliability of new assessment items and their clinical utility as judged by experienced nurse assessors, based on the results from the field test of Version 2.0 of the Resident Assessment Instrument (RAI).

A longitudinal study of risk factors associated with the formation of pressure ulcers in nursing homes.

Objective: To determine risk factors associated with the formation of stage II—IV pressure ulcers in nursing homes.

Delirium Symptoms in Post-Acute Care: Prevalent, Persistent, and Associated with Poor Functional Recovery

OBJECTIVES: To determine the prevalence of delirium symptoms at the time of admission to post‐acute facilities, the persistence of delirium symptoms in this setting, and the association of delirium symptoms with functional recovery.

Last days: a study of the quality of life of terminally ill cancer patients.

Behavior of a number of Quality of Life measures gathered from two samples of terminal cancer patients over the last weeks of their lives are reported. Samples represent patients in the 26 hospices participating in a nationwide U.S. demonstration project and patients in the palliative care units of two Montreal hospitals. The U.S. data reported are quality of life measures made by a lay principal care person (PCP) or trained interviewer; the Montreal measures were made by both an attending doctor and an attending nurse. The general finding, as expected, is one of increasing deterioration in quality of life, with accelerated deterioration between 3 and 1 week of death. Pain follows a somewhat different pattern than other measures. More patients are in either of the extreme categories at an earlier point in time than found for other measures, and there are fewer changes as death is approached. Finally, about 20% of the patients do not fall into extremely low quality of life categories, even in the week prior to death.

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.

Effect of the National Resident Assessment Instrument on Selected Health Conditions and Problems

OBJECTIVE: To evaluate the effect of the implementation of the National Resident Assessment Instrument (RAI) system on selected conditions representing outcomes for nursing home residents.

Measuring change in activities of daily living in nursing home residents with moderate to severe cognitive impairment

BackgroundThe objective of this study was to assess the responsiveness of the Minimum Data Set Activities of Daily Living (MDS-ADL) Scale to change over time by examining the change in physical function in adults with moderate to severe dementia with no comorbid illness who had been resident in a nursing home for over 90 days.MethodsLongitudinal data were collected on nursing home residents with moderate (n = 7001) or severe (n = 4616) dementia in one US state from the US national Minimum Data Set (MDS). Severity of dementia was determined by the MDS Cognitive Performance Scale (CPS). Physical function was assessed by summing the seven items (bed mobility, transfer, locomotion, dressing, eating, toilet use, personal hygiene) on the MDS activities of daily living (ADL) Long Form scale. Mean change over time of MDS-ADL scores were estimated at three and six months for residents with moderate (CPS score of 3) and severe (CPS score of 4 or 5) dementia.ResultsPhysical function in residents with moderate cognitive impairment deteriorated over six months by an average of 1.78 points on the MDS-ADL Long Form scale, while those with severe cognitive impairment declined by an average of 1.70 points. Approximately one quarter of residents in both groups showed some improvement in physical function over the six month period. Residents with moderate cognitive impairment experienced the greatest deterioration in early-loss and mid-loss ADL items (personal hygiene, dressing, toilet use) and residents with severe cognitive impairment showed the greatest deterioration in activities related to eating, a late loss ADL.ConclusionThe MDS-ADL Long Form scale detected clinically meaningful change in physical function in a large cohort of long-stay nursing home residents with moderate to severe dementia, supporting its use as a research tool in future studies.
