Safety assessment for the frail elderly: a comparison of restrained and unrestrained nursing home residents.
OBJECTIVE: To facilitate clinicians' judgement concerning physical restraint decisions by identifying potentially reversible injury risk factors that differentiate representative samples of restrained and unrestrained nursing home residents. DESIGN: Comparison of restrained and unrestrained nursing home residents on a safety assessment for the frail elderly (SAFE) protocol. SETTING: Long-term care facilities in the Greater Los Angeles Area. PARTICIPANTS: One hundred eight physically restrained and 111 unrestrained nursing home residents. INTERVENTION: None. MAIN OUTCOME MEASURES: (1) Internal, Interrater, and test/retest reliability of the overall SAFE protocol and of the four major factors measured by SAFE; (2) The relationship of SAFE scores to expert judgment of resident injury risk; (3) Differences between large samples of restrained and unrestrained residents on specific SAFE score factors. RESULTS: Two walking, one transition, and one judgment factor are reliably measured by the SAFE protocol. SAFE scores were significantly correlated with expert judgment of risk for injury and showed large differences between restrained and unrestrained residents, even after differences in ambulation ability between the two groups were accounted for. CONCLUSION: The SAFE is a reliable protocol that measures behavioral factors related to falls and risk for injury among nursing home residents with a broad range of cognitive impairment. Factors that significantly differentiate restrained and unrestrained groups should be targeted for rehabilitation and remediation in physical restraint reduction efforts. Removing or changing restraints for the large sample (50%) of restrained residents who were not ambulatory will not significantly increase their mobility, since the majority of this group could not independently propel their wheelchairs. Increased mobility for the large group of both restrained and unrestrained residents will likely be realized only if restraint reduction programs are combined with interventions to improve both mobility and the specific behavioral performance factors measured by SAFE.

Use of a portable ultrasound device to measure post-void residual volume among incontinent nursing home residents.
OBJECTIVE: To determine the accuracy of a portable ultrasound device for the assessment of post-void residual (PVR) volume among incontinent nursing home (NH) residents. DESIGN: Prospective, clinical series. SETTING: Seven community-based nursing homes. STUDY POPULATION: Two hundred one consecutively assessed incontinent NH residents who were participating in a larger clinical trial. MEASUREMENTS: PVR volumes measured by trained research associates using a portable ultrasound device and by in-and-out catheterization were compared. The accuracy of the ultrasound was calculated using the volume obtained by catheterization as the gold standard. RESULTS: The ultrasound demonstrated excellent test-retest and interrater reliability. For low PVRs, the device was highly sensitive (.90) for PVR < 50 mL and .95 for PVR < 100 mL) and moderately specific (.71 for PVR < 50 mL and .63 for PVR < 100 mL). For PVRs of more than 200 mL (n = 26), the ultrasound had a sensitivity of .69 and a specificity of .99. CONCLUSION: The portable ultrasound we used was reliable and reasonably accurate for assessing PVR in a representative sample of incontinent NH residents. Because the sensitivity for clinically significant urinary retention (PVR > 200 mL) was only .69, repeated measurements may be necessary to exclude high PVR in individual NH residents. Recent changes in ultrasound design should improve its ease of use and accuracy. Although measuring PVR by ultrasound is much easier and more comfortable than catheterization for both NH residents and staff, the cost of the device may be a barrier to its widespread use in the NH setting.

Using multidimensional health measures in older persons to identify risk of hospitalization and skilled nursing placement.
We examine the relationship between multidimensional measures of function and outcomes in a cohort of older persons admitted to the residential care level of a multi-level long-term care facility. We collected self-reported measures of various aspects of health using the Medical Outcome Study Short-form Health Survey (SF-20) and the Dartmouth COOP charts, as well as performance-based measures of physical and cognitive function. Subjects (mean age 84.3 years) were followed for a median of 557 days. In multivariate analyses, emotional function (measured by either the SF-20 or COOP method) was a predictor of placement in skilled care. Self-reported overall health (measured by either the SF-20 or COOP method) and timed manual performance were predictive of hospitalization. Change on the functional status measures between 2 points in time was not associated with later placement in skilled care except in the case of timed manual performance. In an older population at risk for frequent and numerous health events, this study shows that two popularized self-report methods for assessing function yield results that predict future outcomes of great importance to older persons. However, measures that predict use of long-term care may not predict use of the hospital and vice versa.

Change in self-reported functioning in older persons entering a residential care facility.
We evaluated the responsiveness of measures of function in admissions to a long-term care facility. Between baseline and follow-up assessment, one-fifth or more of the subjects either worsened or improved in most aspects of reported function. We compared two measures of self-reported function (COOP charts and a short-form survey). Convergent validity was observed for changes in pain, social health, and mental health (r = 0.39-0.74), but not for physical functioning. Although the short-form physical function measure discriminated worsening on several performance-based external criteria of physical functioning (area under ROC curves up to 0.82), the COOP and other measures of physical functioning were less likely to do so. All physical function measures were less responsive for detecting improvement. Clinicians and investigators intending to monitor change in function must consider the responsiveness of their measures.

Measuring functioning and health in the very old.
To assess the validity of brief multidimensional measures of health, we studied 155 new residents of a long-term care institution. We collected self-reported measures of various aspects of health, as well as performance-based measures of physical and cognitive function. For six similar health dimensions measured using two self-reported methods, the average correlation between paired health dimensions was 0.64 (nonpaired correlation = 0.36). When we compared self-reports and performance on three closely paired health concepts, the average correlation of paired concepts was 0.49 (nonpaired correlation = 0.22). In a factor analysis, similar health dimensions measured using different methods tended to load on the same factor. Except for manual performance, performance-based and self-reported measures of physical and role function loaded on one factor. We conclude that brief measures of health and self-reported physical functioning in very old persons have acceptable validity.

Decisions about enteral tube feeding among the elderly.
OBJECTIVE: To determine choices about enteral tube feeding and factors associated with deciding to accept or forego this intervention in a group of ambulatory non-demented older individuals. DESIGN: Descriptive survey. SETTING AND PARTICIPANTS: Thirty four volunteers from a senior adult day center and 34 volunteers from the residential care section of a multilevel long-term care institution, mean age 77.8. INTERVENTION: Structured interview using a hypothetical clinical vignette in simplified language, story-book format depicting an irreversibly and severely impaired state of health. MEASUREMENT: Choice of whether to accept or forego enteral tube feeding based on the clinical vignette. RESULTS: Thirty four (50%) decided to accept and 34 (50%) chose to forego enteral tube feeding in the situation presented in the vignette. No demographic, cognitive, or affective factors were associated with the decision. Presentation of the vignette and associated questions were not anxiety-provoking or upsetting to the vast majority of participants. CONCLUSION: A hypothetical clinical vignette depicting a state of severely impaired health resulted in 34 (50%) of 68 ambulatory non-demented older individuals deciding to accept enteral tube feeding. No factors we examined were strongly associated with the decision. The vignette and discussion were not anxiety-provoking when presented in the format used in this study. Advance-directive discussions about enteral tube feeding and other health care decisions, using understandable hypothetical clinical vignettes that describe risks and benefits that might influence decisions, should be encouraged in the practice of geriatric medicine.

Characteristics and quality of prescribing by doctors practicing in nursing homes.
OBJECTIVES: To describe the professional characteristics of doctors practicing in nursing homes and to determine whether those characteristics correlate with quality of prescribing. DESIGN: A prospective, cohort study. PARTICIPANTS: 306 physicians practicing in 12 nursing homes in greater Los Angeles. MEASUREMENTS: We surveyed doctors about their age, sex, education, credentials, and NH practice. We also determined medication orders for a 1-month period and evaluated them using explicit criteria for appropriateness developed by an expert panel. RESULTS: We obtained data from 72% of MDs. Respondents had a mean age of 53 years (29-78) and were 94% male. Fifty-seven percent trained in internal medicine, 20% graduated outside the US or Canada, 67% were board certified in their declared specialty, and 5% had a certificate of added qualification in geriatrics (CAQ). Sixteen percent spent > 10% of their professional time in NHs, and 46% had NH practices that were > 20% Medicaid; most did not consult psychiatrists when prescribing psychoactive drugs. Forty percent of residents had at least one inappropriate prescription. The characteristics of doctors associated with the best prescribing quartile were female sex, CAQ, no board certification, and frequent consultation with psychiatrists. The characteristics of doctors in the most inappropriate quartile were older age, graduation from medical school before 1965, graduation from US medical school, small NH practice, and infrequent consultation with psychiatrists. CONCLUSIONS: Although the quality of prescribing in nursing homes is related to some physician characteristics, the relationships are not those most commonly stated.

Urinary incontinence in nursing homes: incidence, remission and associated factors.
OBJECTIVE: To determine the incidence and remission rates of daytime urinary incontinence (UI) in a cohort of newly admitted nursing home (NH) residents. DESIGN: Prospective cohort study. SETTING: Eight proprietary NHs in Maryland. SUBJECTS: Four hundred thirty new admissions age 65 or older who were participants in a larger prospective study of mental morbidity and adjustment to the NH. MEASURES: Nurses aides' reports of continence status, psychiatric examinations, and nursing staff assessments of mobility at 2 weeks, 2 months, and 1 year after NH admission. RESULTS: The prevalence of daytime UI at admission was 39% in both females and males. Among the 293 members (68%) of the admission cohort remaining in the NHs 2 months after admission, the incidence of daytime UI was 27% (21% in females, 51% in males); daytime UI resolved in 23% (24% in females, 20% in males). Among the 178 members (41%) of the admission cohort remaining in the NHs 1 year after admission, the incidence of daytime UI between 2 months and 1 year after admission was 19% (16% in females, 46% in males); daytime UI resolved in 22% (23% in females, 14% in males). The continence status of about two-thirds of residents remaining in the NH at 1 year after admission was stable over time: 22% had daytime UI, and 42% were continent at all three data collection points. The development of daytime UI was associated with male sex, the diagnosis of dementia, fecal incontinence, and the inability to ambulate or transfer independently. Resolution of daytime UI was associated with the absence of these characteristics. CONCLUSIONS: Despite limitations attributable to the method of defining UI and potential biases related to the attrition of the admission cohort over time, this is the first large prospective study to examine the incidence and remission patterns of daytime UI among NH residents. The strong association between UI and dementia was validated for the first time by direct psychiatric examinations. Sex and mobility are also closely associated with the development and remission of UI in this setting. This study provides some valuable data that can be used to assess the impacts of the recently developed Resident Assessment Protocol for UI and Agency for Health Care Policy and Research Clinical Practice Guidelines.

Nighttime sleep and bed mobility among incontinent nursing home residents.
OBJECTIVE: To describe sleep and body movement patterns in incontinent nursing home residents for the purpose of determining if the residents require nighttime changing and body repositioning on a 2-hour schedule. DESIGN: Cross-sectional survey. SETTING: Four nursing homes. PARTICIPANTS: 118 nursing home residents. MEASUREMENTS: Over two nights, bedside monitoring equipment recorded wrist activity (as a proxy measure for sleep) and body movements of both the shoulder and hip areas in consecutive 2-minute intervals. Specific outcome measures were: (1) Average duration of a sleep episode, peak duration of a sleep episode, and percent of time in bed asleep. (2) The number of 2-minute intervals in which a large movement (45 degree turn) at the shoulder and hip was noted per hour of recording for each resident. (3) The number of resident-initiated, rather than staff-initiated, large movements at the shoulder and hip that occurred within the same 2-minute intervals. RESULTS: There was large variability in all sleep measures; however, on average, residents slept 66% of the time they were in bed. The distribution of these measures suggests that sleep was punctuated with frequent nighttime awakenings. Thirty-three percent of the incontinent residents demonstrated very low levels of resident-initiated movement at the shoulder and hip. Sixty-six percent demonstrated at least one large movement at the shoulder and hip per hour during periods of sleep as well as during periods of wake. CONCLUSION: The majority of incontinent nursing home residents self-initiate sufficiently frequent movements at both the shoulder and hip so as not to be in need of frequent repositioning by nursing staff. Since the sleep of many of these residents is also characterized by frequent awakenings, incontinent nursing home residents may benefit from a schedule of nursing care at night that considers sleep of equal importance to incontinence care and body repositioning.

The nighttime environment, incontinence care, and sleep disruption in nursing homes.
OBJECTIVE: To evaluate the association between noise, light, nursing care practices, and nighttime awakenings in incontinent nursing home residents. DESIGN: Cross-sectional survey. SETTING: Four long-term care nursing facilities. PARTICIPANTS: One hundred eighteen incontinent nursing home residents. MEASUREMENTS: Over two nights, bedside monitoring equipment recorded wrist activity, resident bed movements, and environmental noise and light changes in consecutive 2-minute intervals. Changes in sleep and bed movement were compared with changes in noise and light that occurred within the same or proximal 2-minute intervals. Noise and light changes in combination with large resident movement at the hip and shoulder were interpreted as related to incontinence care based on observational measures. Specific outcome measures were: (1) the number of noise and light changes as well as staff care practices that did not wake the resident during periods of consecutive sleep, ie, sleep lasting a minimum of 10 minutes; (2) the number of noise and light changes as well as staff care practices that occurred immediately before or during the 2-minute intervals during which a resident woke from a period of consecutive sleep; and (3) the number of such staff care practices that were related to incontinence care. RESULTS: Noise and light changes associated with both general environmental events and more specific nurse care practices were associated with 50% of all waking episodes of 4 minutes or longer and 35% of all waking episodes of 2 minutes or shorter. The major sources of all noise were traced to nursing staff. Eighty-seven percent of all incontinence care practices were associated with episodes of waking. CONCLUSION: The data reported in this paper document that general environmental noise and incidents of nursing care practices, particularly those related to incontinence care, are responsible for a substantial amount of the sleep fragmentation that is common among nursing home residents.

Total quality management: administrative and clinical applications in nursing homes.
OBJECTIVE: Describe the application of the Total Quality Management (TQM) model to the unique work force, resident population, and regulatory issues that characterize long term care settings. DESIGN: The key differences between TQM and current management and training practices in nursing homes are described. A specific data-based example is provided of a successful TQM application to health care involving clinical work processes related to incontinence care. CONCLUSION: Significant organizational and clinical obstacles must be overcome if TQM is to improve the quality of life and satisfaction of nursing home residents and their families as it has improved the efficiency and product quality in hospital and non-health-care settings.

Inappropriate medication prescribing in skilled-nursing facilities.
OBJECTIVE: To quantify the appropriateness of medication prescriptions in nursing home residents. DESIGN: Prospective, cohort study. SETTING: Twelve nursing homes in the greater Los Angeles area. PARTICIPANTS: A total of 1106 nursing home residents. MAIN OUTCOME MEASURES: The appropriateness of medication prescriptions was evaluated using explicit criteria developed through consensus by 13 experts from the United States and Canada. These experts identified 19 drugs that should generally be avoided and 11 doses, frequencies, or durations of use of specific drugs that generally should not be exceeded. RESULTS: Based on the consensus criteria, 40% of residents received at least one inappropriate medication order, and 10% received two or more inappropriate medication orders concurrently; 7% of all prescriptions were inappropriate. Physicians prescribed a greater number of inappropriate medications for female residents. Regression analysis, corrected for clustering effects within facilities, showed that a greater number of inappropriate medication prescriptions were ordered in larger nursing homes. Inappropriate prescriptions were not related to the proportion of Medicaid (Medi-Cal) residents or the number of physicians practicing in the homes. CONCLUSIONS: Inappropriate medication prescribing in nursing homes is common. Female residents and residents of large nursing homes are at the greatest risk for receiving an inappropriate prescription.

A computerized system for identifying and informing physicians about problematic drug use in nursing homes.
With growing concern over the quality of medication use in nursing homes, physicians, administrators, pharmacists, and regulators are looking for effective and efficient methods to improve it. Pharmacy consultation alone appears to be ineffective in controlling the use of inappropriate drugs. We describe here a computerized drug utilization review system designed for use in nursing homes. The system evaluates the appropriateness of medication use by criteria developed through the consensus of experts in geriatrics and specifically designed to address the pharmacological needs of elderly, nursing home residents. The program not only determines the frequency of inappropriate prescriptions, but produces written, educational statements to be given to prescribing physicians. These statements can also be given to nurses to educate them about issues in geriatrics pharmacology. Additionally, the system produces medication order forms that may help focus physicians' attention on the need to evaluate drugs individually.

Geriatric urinary incontinence.
Urinary incontinence (UI) is now recognized as a prevalent, physically and emotionally disruptive, and costly health problem in the geriatric population. Because incontinence may be a manifestation of a subacute or reversible process within or outside of the lower urinary tract, and because effective treatment is available, it is important for primary care physicians to identify and appropriately assess incontinence in their geriatric patients. The initial evaluation of an incontinent geriatric patients. The initial evaluation of an incontinent geriatric patient includes a targeted history and physical examination, urinalysis, and simple tests of lower urinary tract function. Potentially reversible conditions that may be causing or contributing to the incontinence, such as delirium and urinary tract infection (UTI), should be identified and managed. Patients who may benefit from further testing, including urologic or gynecologic examination and/or complex urodynamic tests, should be identified and referred. Several therapeutic modalities can be used to treat geriatric UI. Behavioral therapies are noninvasive and effective, both in functional community-dwelling geriatric patients and in functionally impaired nursing home residents. Behavioral therapies include bladder training, pelvic muscle exercises, biofeedback, scheduled toileting, habit training, and prompted voiding. Pharmacologic therapy is often used in conjunction with behavioral therapy. For stress incontinence, alpha-adrenergic drugs are used and can be combined with topical or oral estrogen therapy in women. For urge incontinence, pharmacologic treatment involves drugs with anticholinergic and direct bladder muscle relaxant properties. Pharmacologic therapy for overflow incontinence is generally not effective on a long-term basis. Surgical treatment is indicated when a pathologic lesion such as a tumor is diagnosed, or when anatomic obstruction is believed to be the cause of the patient's symptoms. Surgical treatment of stress incontinence can be highly effective in properly selected women. Nonspecific, supportive treatments are also important in managing geriatric UI. Education for patients and caregivers is critical for the success of most therapies. Environmental manipulations and the appropriate use of toilet substitutes are especially important in frail, functionally impaired patients. Highly absorbent adult undergarments are helpful for managing many patients, but should not be used as the initial response to incontinence, and are best used in conjunction with more specific treatment whenever possible. Chronic indwelling catheterization should only be used to manage incontinence when it is associated with clinically significant urinary retention, skin conditions that cannot heal because of incontinence, or severe illness that makes the catheter the most comfortable method of management.(ABSTRACT TRUNCATED AT 400 WORDS)
