The value of assessing falls in an elderly population. A randomized clinical trial.

OBJECTIVE: To measure the effects of a specialized postfall assessment intended to detect causes and underlying risk factors for falls, and to recommend preventive and therapeutic interventions. DESIGN: Randomized, controlled trial. SETTING: A long-term residential care facility for elderly persons. SUBJECTS: Within 7 days of a fall, 160 ambulatory subjects (mean age, 87 years) were randomly assigned to receive either a comprehensive postfall assessment (intervention group, n = 79) or usual care (control group, n = 81). INTERVENTION: The postfall assessment included a detailed physical examination and environmental assessment by a nurse practitioner; laboratory tests; electrocardiogram; and 24-hour Holter monitoring. Probable cause or causes for the fall, identified risk factors, and therapeutic recommendations were given to the patient's primary physician. MEASUREMENTS AND MAIN RESULTS: Through use of the assessment, many remediable problems (for example, weakness, environmental hazards, orthostatic hypotension, drug side effects, gait dysfunction) were detected. At the end of the 2-year follow-up period, the intervention group had 26% fewer hospitalizations (P less than 0.05) and a 52% reduction in hospital days (P less than 0.01) compared with controls. Patients in the intervention group had 9% fewer falls and 17% fewer deaths than controls by 2 years, but these trends were not statistically significant. CONCLUSIONS: Our study suggests that falls are a marker of underlying disorders easily identifiable by a careful postfall assessment, which in turn can reduce disability and costs.

The value of Holter monitoring in evaluating the elderly patient who falls.

Ambulatory cardiac (Holter) monitoring is often recommended in the routine evaluation of patients who fall; however, the prevalence of arrhythmias in old people is high, and the usefulness of such monitoring is unproven. As part of a large study of institutionalized elderly fallers, we compared Holter findings of fallers (N = 51) with a group of nonfallers (N = 27) having similar medical and demographic characteristics. Prevalence of ventricular arrhythmias was 82% in each group, and all patients had supraventricular arrhythmias. The mean number of ventricular and supraventricular couplets and runs did not differ between groups. There was no difference in severity of arrhythmias between fallers and nonfallers; in fact, fallers had slightly fewer Lown 4B arrhythmias than nonfallers (10% vs 18%, NS). Prevalence of heart disease was 78% in both groups and was associated with increased ventricular ectopy in the form of runs and couplets (P less than .05). No symptoms were reported during the Holter monitoring. We conclude that Holter monitoring should not be a routine part of the work-up of the patient who falls.

Predictors of falls among elderly people. Results of two population-based studies.

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 physical assessment in all subjects using a standardized protocol and physician consultation. Fallers in both populations were significantly more physically and functionally impaired than control subjects. Logistic regression identified hip weakness, poor balance, and number of prescribed medications as factors most strongly associated with falling among institutionalized subjects. A fall prediction model was developed from these findings yielding 76% overall predictive accuracy (89% sensitivity, 60% specificity). Using the model, the predicted 1-year risk of falling ranged from 12% for persons with none of the three risk factors to 100% for persons with all three risk factors. Findings among noninstitutionalized subjects were similar. These data support the concept of performing focused fall risk assessments to identify elderly patients at high risk for falling.

The use of anencephalic infants as organ sources. A critique.

The recent abandonment of the only active US protocol for harvesting organs from anencephalic "donors" indicates both the practical and the ethical problems inherent in such an effort. Various data suggest that surprisingly few such organs would actually end up benefiting other children. Attempts to revise either the Uniform Anatomical Gift Act or the Uniform Determination of Death Act to allow organ removal from spontaneously breathing anencephalic infants face major ethical objections. Even if this posed no ethical problem in theory, the ultimate harm to society would not be offset by the good of the few surviving recipients of these organs. Furthermore, providing anencephalic infants with intensive care would tend to preserve the brain stem as effectively as the other organs, predictably rendering the occurrence of brain death unlikely. Thus, despite the great need for newborn organs, anencephalic infants are not as attractive a source as some had hoped.
