A study was performed to identify and rank risk factors for falling among populations of institutionalized (fallers, N = 79, nonfallers, N = 70) and noninstitutionalized (fallers, N = 34, nonfallers, N = 34) elderly persons. Fallers were matched by age, sex, and living location to nonfaller control subjects. A nurse practitioner performed a comprehensive(More)
PURPOSE (1) to evaluate objectively changes in cognitive function and electrophysiologic characteristics associated with hypothyroidism of varying severity and duration in primarily older persons; (2) to determine whether these changes are reversible when a euthyroid state has been attained after treatment with thyroid hormone. SUBJECTS AND METHODS We(More)
OBJECTIVES To determine whether an intervention that combines low-intensity exercise and incontinence care offsets some of its costs by reducing the incidence of selected health conditions in nursing home residents. DESIGN Randomized, controlled trial with the incidence and costs of selected, acute conditions compared between a 6-month baseline and an(More)
OBJECTIVES To determine whether nursing homes (NHs) that score in the extreme quartiles of pressure ulcer (PU) prevalence as reported on the Minimum Data Set (MDS) PU quality indicator provide different PU care. DESIGN Descriptive, cohort. SETTING Sixteen NHs. PARTICIPANTS Three hundred twenty-nine NH residents at risk for PU development as determined(More)
OBJECTIVE To determine if detectable serum tumor necrosis factor alpha (TNF) levels are associated with higher mortality in nursing home residents. SUBJECTS AND METHODS The basal serum concentrations of TNF and interleukin-1 alpha (IL-1) were measured in 129 elderly nursing home patients (mean age of 89 years), and survival in the cohort was monitored(More)
PURPOSE The objective of this work was to determine if nursing homes that score differently on prevalence of depression, according to the Minimum Data Set (MDS) quality indicator, also provide different processes of care related to depression. DESIGN AND METHODS A cross-sectional study with 396 long-term residents in 14 skilled nursing facilities was(More)
BACKGROUND Cost-effectiveness of low-air-loss beds for the healing of pressure ulcers was analyzed in the nursing home setting. A statistical model of pressure ulcer healing was used to estimate cost-effectiveness based on patient and ulcer characteristics. METHODS Results of a previous randomized trial (84 patients from three nursing homes in Los(More)
The mean incidence of falls in nursing homes is 1.5 falls per bed per year (range 0.2-3.6). The most common precipitating causes include gait and balance disorders, weakness, dizziness, environmental hazards, confusion, visual impairment, and postural hypotension. The most important underlying risk factors for falls and injuries include some of these same(More)
PURPOSE To determine if nursing homes that score in the lower 25th percentile (low prevalence) versus the upper 75th percentile (high prevalence) on each of two Minimum Data Set (MDS) incontinence quality indicators provide different incontinence care processes DESIGN Cross-sectional. SUBJECTS 347 long-term residents in 14 skilled nursing facilities for(More)
BACKGROUND Despite vaccination, influenza commonly causes morbidity and mortality in institutional settings. Influenza control with rimantadine and amantadine is limited by emergence and transmission of drug-resistant influenza A variants, ineffectiveness against influenza B, and toxicity. This study evaluated the efficacy and tolerability of zanamivir(More)
