The nursing home at night: effects of an intervention on noise, light, and sleep.

OBJECTIVES: The sleep of nursing home residents is fragmented by frequent awakening episodes associated, at least in part, with environmental variables, including noise and light changes. The purpose of this study was to improve sleep by reducing the frequency of nighttime noise and light changes. PARTICIPANTS AND SETTING: Two hundred sixty-seven incontinent nursing home residents in eight nursing homes. DESIGN: A randomized control group design with a delayed intervention for the control group. MEASUREMENTS: Bedside noise and light monitors recorded the number of 2-minute intervals at night with peak sounds recorded above 50 dBs and the number of light changes of at least 10 lux between adjacent 2-minute intervals. Daytime behavioral observations measured sleep and in-bed time during the day, and wrist activity was used to estimate sleep at night. Awakening events associated with the environmental variables were derived from the wrist activity data. INTERVENTION: A behavioral intervention implemented between 7:00 p.m. and 6:00 a.m. that involved feedback to nursing home staff about noise levels and implementation by research staff of procedures to both abate noise (e.g., turn off unwatched television sets) and to individualize nighttime incontinence care routines to be less disruptive to sleep. RESULTS: Noise was reduced significantly, from an average of 83 intervals per night with peak noises recorded above 50 dBs to an average of 58 intervals per night in the group that received the initial intervention, whereas noise in the control group showed no change (MANOVA group x time P < .001). All 10-dB categories of noise from 50 to 90+ dBs were reduced, and light changes were reduced from an average of four per night per resident to two per night (P < .001). Despite these significant changes in the environmental variables, there was a significant differential improvement in the intervention group on only two night sleep measures: awakening associated with a combination of noise plus light (P < .001) and awakening associated with light (P < .001). However, there was a significant correlation between change in noise and change in percent sleep from baseline to intervention (r = -.29, P < .05), suggesting that the intervention did not reduce noise to low enough levels to produce a significant improvement in sleep. The intervention effects on all environmental variables were replicated in the delayed intervention group, who again showed significant improvement on the same sleep measures. Observations of day sleep and in-bed time did not change over the phases of the trial for either group. CONCLUSION: The significant reductions in noise and light events resulting from the intervention did not lead to significant improvements in the day sleep and most night sleep measures. An intervention that combines both behavioral and environmental strategies and that addresses daytime behavioral factors associated with poor sleep (e.g., excessive time in bed) would potentially be more effective in improving the night sleep and quality of life of nursing home residents.

Development and validation of a physical examination scale to assess vaginal atrophy and inflammation.

BACKGROUND: The assessment of vaginal atrophy is central to menopause-related research and clinical practice. However, methods of grading vaginal atrophy have not been subjected to reliability and validity assessments. OBJECTIVE: To assess the validity and reproducibility of selected vaginal examination findings proposed to represent vaginal atrophy and inflammation. DESIGN: Cross-sectional study. PARTICIPANTS: A convenience sample of 40 postmenopausal volunteers with past history of breast cancer. MEASUREMENTS: Participants completed questionnaires to assess vaginal symptoms. Pelvic examinations were carried out using specified criteria to assess the vaginal appearance. Vaginal cytological smears and pH measurements were performed using standardized techniques. RESULTS: A four-item physical examination atrophy scale had an alpha reliability of 0.48 and was statistically significantly correlated with pH (r = 0.55) and parabasal cells (r = 0.50). A three-item physical examination inflammation scale had an alpha reliability of 0.45. It was not significantly associated with vaginal smear-measured inflammation. Masked inter-rater agreement for the examination was 90%. Self-reported symptoms of itching/irritation or dryness were poorly related to findings on physical examination. CONCLUSIONS: These results offer objective validation that the physical characteristics proposed to represent atrophy are related to biomarkers of this condition. A relationship between examination characteristics believed to represent inflammation and inflammation biomarkers was not upheld.

Sleep hygiene in physically dependent nursing home residents: behavioral and environmental intervention implications.

The purpose of this report is to summarize data from a sample of 230 residents in eight nursing homes (NHs) that are relevant to the development of environmental and behavioral interventions for sleep. Four conclusions can be drawn: (1) there is strong evidence that the nighttime sleep of these residents was adversely affected by environmental noise and light; (2) residents appear to spend substantial time in bed and sleeping during the day; (3) there are significant differences between some homes in the amount of time that residents spend in bed and sleeping during the day, as well as the frequency of nighttime awakenings associated with environmental events; and (4) residents' preference and nighttime noise source data suggest that a multifaceted intervention to improve sleep hygiene could successfully implemented in the NH setting. An intervention addressing these issues may result in improved sleep and overall well-being for a substantial portion of the NH population.

Nighttime urinary incontinence and sleep disruption among nursing home residents.

OBJECTIVE: To examine the relationship of urinary incontinence episodes to sleep disruption in a sample of nursing home residents. DESIGN: Descriptive, case series. SETTING: Three community nursing homes. PARTICIPANTS: Seventy-three incontinent residents of three nursing homes participating in a trial of a behavioral intervention for nighttime urinary incontinence. MEASUREMENTS: Data were collected during a baseline and repeat baseline period about 2 months later in nursing homes serving as controls for the intervention homes. Incontinence episodes were identified by incontinence pads, which were wired to detect wetness of 10 mL or more. Sleep was monitored by wireless wrist actigraphs. Noise and light changes were monitored by bedside recording devices. MAIN RESULTS: Recordings covered 403 nights, during which 1715 awakenings from 10 consecutive minutes of sleep were detected as were 1168 incontinent episodes. Only 4% of the awakenings were associated with an incontinence episode, and only 23% of the incontinence episodes occurred during periods of at least 10 consecutive minutes of sleep. Of the latter episodes, only 12% appeared to awaken the resident. CONCLUSIONS: Our data raise questions about the relevance of incontinence episodes to sleep disruption among chronically incontinent nursing home residents. Our findings must be interpreted cautiously because of limitations in the technologies and definitions we used to identify sleep, awakenings, and incontinence episodes. Although logistically and technically difficult to perform, studies using polysomnographic recordings of sleep are needed to examine further these important associations.

The nighttime environment and incontinence care practices in nursing homes.

OBJECTIVES: To determine the variability in noise, light, and incontinence care practices between nursing homes (NHs) and the association between these factors and residents' nighttime sleep. DESIGN: Prospective descriptive study of a sample of incontinent NH residents. SETTING: Ten nursing homes. SUBJECTS: Two hundred twenty-five incontinent NH residents. MAIN OUTCOME MEASURES: Measurements of residents' sleep by wrist actigraphs, bed mobility by pressure sensitive Kynar strips, and environmental noise and light changes were recorded by bedside monitors in consecutive 2-minute intervals for two 10-hour nighttime data collection periods (7 PM to 5 AM). RESULTS: Forty-two percent of waking episodes lasting 4 minutes or longer were associated with noise, light, or incontinence care events. Twenty-two percent of waking episodes of 4 minutes or longer were associated with noise alone, 10% with light or light + noise, and 10% with incontinence care routines. Seventy-six percent of all incontinence care practices resulted in awakenings. There was variability between the 10 NHs, with the percentage of waking episodes associated with environmental events (noise, light, or incontinence care events) ranging from 23.6 to 66.0%. CONCLUSION: Noise and incidents of incontinence care practices were associated with a substantial amount of sleep disruption in residents in all 10 nursing homes, even though there was variability between homes. Interventions minimizing such environmental events are needed to promote better sleep in incontinent NH residents.

Developing rehabilitative behavioral interventions for long-term care: technology transfer, acceptance, and maintenance issues.

Rehabilitative behavioral interventions that are documented in clinical trials to improve nursing home resident outcomes and are recommended by practice guidelines are often not adapted for daily use in nursing homes and other long-term care (LTC) facilities. Failure to evaluate issues other than clinical efficacy when developing interventions contributes to this gap between efficacy and effectiveness in practice. A potential solution is a research model that supplements traditional clinical intervention research with methodology designed specifically to evaluate the ability of LTC facilities to implement the interventions. This paper discusses several critical issues of intervention and implementation that should be addressed, including targeting interventions, advocacy, cost-effectiveness, training, and quality control. We also describe how clinical trials could be designed and staged to increase the probability that effective interventions will be implemented in the day-to-day care of frail older patients in LTC facilities.

Arginine vasopressin levels in nursing home residents with nighttime urinary incontinence.

OBJECTIVES: To examine the relationship between diurnal urine volume and plasma arginine vasopressin levels (AVP) in nursing home residents with nighttime urinary incontinence and a comparison group of frail but nondemented, continent geriatric board and care residents. DESIGN: Case series. SETTING: Four nursing homes and two board and care facilities. PARTICIPANTS: Sixty-two nursing home residents and 27 board and care residents. MEASUREMENTS: Daytime (7:00 a.m. to 7:00 p.m.) and nighttime (7:00 p.m. to 7:00 a.m.) urine volumes of incontinent nursing home residents were measured over 3 days and 3 nights by reweighing preweighed adults diapers and toileting inserts emptied by research staff for the comparison group. AVP levels were drawn in the early morning (5:00 a.m. to 7:00 a.m.) before subjects arose and in the evening after an hour of lying in bed (8:00 p.m. to 11:00 p.m.), and plasma levels were determined by radioimmunoassay. RESULTS: Half of the nursing home residents and 82% of the comparison group had night/total urine volume ratios > or = 50%. Forty-nine percent of the total of 89 subjects had undetectable morning AVP levels, 61% had undetectable evening AVP levels, and 42% had undetectable AVP levels in both morning and evening. There were no significant differences in AVP levels between those with night/total urine volume ratios > or = 50% and < 50% in either the nursing home or comparison groups though the small number of comparison group subjects with ratios < 50% may have limited our statistical power to detect differences. CONCLUSION: Our data suggest that a substantial proportion of both nursing home residents with nighttime incontinence and frail geriatric patients with a reversal of the normal diurnal pattern of urine excretion have an accompanying deficiency in AVP production and/or secretion. More detailed physiologic studies are needed to understand better the pathophysiology of geriatric nocturia and nighttime incontinence and the role that AVP deficiency may play in these conditions. Until such studies are carried out, we do not recommend the routine use of exogenous AVP for geriatric patients with unexplained nocturnal polyuria.

Urinary incontinence in the elderly. Causes and treatment options.

Urinary incontinence is a prevalent and distressing condition that affects > 30% of elderly individuals. A wide variety of treatment modalities is available, and can be effective in reducing or eliminating the symptoms and adverse consequences of urinary incontinence. Pharmacological therapy is an important component of the successful management of this condition, but the agents currently used do not act selectively on the lower urinary tract. Adverse effects of drug treatment are common, and are especially problematic in the elderly. A careful assessment of the type of urinary incontinence and the institution of a rational management programme are the keys to improvement or even cure in patients with this condition.

Policy without technology: a barrier to improving nursing home care.

Standards of care are written for nursing homes without a realistic assessment of whether there is an intervention protocol or resources to meet these standards. This situation produces unfair pressures on nursing home providers, who react with paper compliance strategies, and creates a barrier to implementing new interventions that do meet care standards once they are developed. This article explores this barrier and illustrates examples of interventions that have been attempted in nursing homes using a continuous quality improvement model. The development of quality indicators based on assessment data available in all nursing homes is a step toward making the survey process more focused on outcomes rather than on paper compliance. Much more research is needed to design effective clinical interventions and to provide nursing homes with the technologies necessary to target them. Internal nursing home quality assurance programs based on principles of continuous quality improvement, with reinforcement from the external survey process, are suggested as a strategy to maintain clinically effective interventions. Applied research centers based in long-term care facilities should be supported in order to accomplish such research designed to improve the care and quality of life our increasing frail nursing home population.

Selecting nursing home residents for satisfaction surveys.

Many cognitively impaired nursing home (NH) residents are excluded from interviews measuring quality of life or care based on the belief that these residents cannot accurately answer questions. These exclusions are based on subjective criteria and ignore individual differences among cognitively impaired NH residents. This study describes a screening rule based on four minimum data set (MDS) indicators that provides an objective method for identifying residents capable of accurate report. Sixty percent of a sample of 83 NH residents who could answer yes or no questions about their care could do so accurately. Eighty-one percent of the sample was correctly classified by the MDS indicators.

Aging and the lower urinary tract.

Lower urinary tract symptoms and disorders are prevalent and bothersome in the rapidly growing aging population. Common symptoms include urinary frequency, nocturia, urgency, and incontinence. Among older men, symptoms of voiding difficulty, such as hesitancy, slow stream, and straining, are also common. A variety of aging changes, as well as age-associated disease, predispose older people to the development of lower urinary tract symptoms. Medications used to treat conditions outside the lower urinary tract also can contribute to these symptoms. Physicians and other health professionals should routinely ask specific questions about lower urinary tract symptoms in their older patients and evaluate them thoroughly when they are present.

Postmenopausal vaginal atrophy and atrophic vaginitis.

Menopause is associated with a marked reduction in endogenous estrogen production. Lower levels of circulating blood estrogen have various deleterious effects, including those on the lower urinary tract. The vaginal epithelium becomes atrophied and dry, which can cause vaginal discomfort, itching, and dyspareunia. The epithelium may become inflamed and contribute to urinary symptoms, including frequency, urgency, dysuria, and incontinence. Diminished estrogen effects on periurethral tissues can contribute to pelvic laxity and stress incontinence. Changes in vaginal pH and normal flora may predispose older women to urinary tract infection. Although estrogen replacement therapy can result in maturation of the vaginal epithelium, the optimal form of administration and the dosage regimen for improving symptoms and quality of life of the geriatric female population have not been well studied.

Skin disorders and moisture in incontinent nursing home residents: intervention implications.

OBJECTIVE: To provide data needed to design an intervention trial to prevent or treat skin disorders in a high risk, incontinent nursing home population. DESIGN: The incidence and prevalence of nine common skin disorders were measured prospectively over a 60-day period using trained observers. Urinary and fecal incontinence frequency were measured over 24 hours, and mobility was measured with subjects both in and out of bed. Direct measures of skin moisture were taken with an impedance device in the presence and absence of urinary incontinence. Multiple regression analyses were used to relate the incontinence and mobility variables to the presence and development of skin disorders. SETTING: Four nursing homes. PARTICIPANTS: One hundred incontinent nursing home residents. MAIN OUTCOME MEASURES: Prospective measures of nine common skin disorders and skin moisture in four perineal regions under continent and incontinent conditions. RESULTS: All subjects had at least one skin condition identified during the 60-day data collection period. The most commonly observed skin condition was blanchable erythema, which occurred in 94% of the subjects, predominantly in the front and back regions that were closest to the urethra and rectum. Twenty-one percent of residents developed either a Stage 1 (nonblanchable erythema) or 2 pressure ulcer. All skin conditions were transient when measured every 3 weeks with the exception of blanchable erythema, which showed stability. Stage 3 or greater pressure ulcers and edema were not observed, and interrater reliability for the measure of papules was poor. Measures of urinary and fecal incontinence severity were correlated with blanchable erythema severity, and blanchable erythema and low bed mobility were predictive of pressure ulcer severity. Blanchable erythema severity was also predictive of Stage 1 and 2 pressure ulcers. Skin moisture levels in the back perineal farthest from the rectum (peripheral) were affected most by urinary incontinence. CONCLUSION: A trial to detect a 50% preventive effect on Stage 1 and 2 pressure ulcers would require that 167 subjects be monitored for 60 days. The transient nature of the skin effects require that skin be monitored at least once a week. Because blanchable erythema is so prevalent and appears to be associated with more severe skin conditions, it would make an excellent marker for beginning to assess the potential preventive effects of various interventions on the incidence of pressure ulcers and other related skin disorders in incontinent patients. It is likely that the back area peripheral to the urethra and rectum would experience the greatest benefit from an intervention trial to reduce moisture caused by incontinence.

Perioperative care in the elderly urologic patient.

This article summarizes the preoperative evaluation and postoperative care recommended for elderly patients undergoing urologic procedures. Most of the common issues faced during the perioperative period are discussed, but many other topics require reference to other sources or consultation with specialists. A thorough preoperative evaluation is needed, and meticulous attention to postoperative care is mandatory. The most important common problem is assessment of cardiovascular risk in patients and a general approach is suggested by the authors. Surgical risk in elderly patients is increased, but most of this excess risk is because of associated comorbid conditions. Effective pre- and postoperative assessment and care can minimize this risk and maximize the chances of a successful outcome.

Exercise with physically restrained nursing home residents: maximizing benefits of restraint reduction.

OBJECTIVE: To evaluate an exercise protocol designed to improve strength and mobility, and to decrease injury risk factors in physically restrained nursing home residents. DESIGN: A randomized controlled trial. PARTICIPANTS: Ninety-seven residents were randomized into either exercise or control groups. Thirty-five exercise and 37 control group residents completed all post-assessments after a 9-week trial. INTERVENTION: Walking or wheelchair movement training was supplemented by rowing exercise three times per week. Practice in behaviors related to safe movement was provided incidental to the exercise. MEASUREMENT: Endurance, speed, and injury risk measures relevant to walking, wheelchair propulsion, and standing were assessed by standardized protocols. Rowing endurance, rowing range of motion, and handgrip strength measures were collected to assess the effect of the rowing component of the exercise protocol. RESULTS: Fifty-four percent of the subjects who provided consent did not complete the protocol because of health status changes, lack of cooperation, or physical limitations that precluded exercise. The subjects who completed the exercise program showed significant improvement on injury risk and measures related to upper body strength (handgrip strength, rowing endurance, wheelchair endurance, and speed). Measures related to lower body strength did not significantly improve. CONCLUSION: Physically restrained residents are very frail, and it is difficult to implement a long-term exercise program with many residents because of the frailty. However, a substantial proportion of residents did cooperate well with the exercise program and showed improvement on measures correlated with decreased injury risk. The exercise program could be easily modified to include more lower body exercise, and the resultant protocol would be an important adjunct to restraint reduction programs.
