Utilization of a screening tool to identify homebound older adults at risk for falls: validity and reliability.

PURPOSE: This study examined the reliability and validity of a Falls Risk Assessment (FRA) tool developed to identify risk factors associated with falls in homebound older adults. DESIGN AND METHODS: FRA scores of 307 Medicare-eligible adults over 65 admitted sequentially to a home health agency (HHA) were analyzed retrospectively using a case-control design. A total of 18 subjects participated prospectively in assessment of criterion-related validity and rater reliability. RESULTS: Mean FRA scores of fallers were significantly higher than non-fallers (10.13, 7.2, respectively; p < 0.05). The FRA and Performance-Oriented Mobility Assessment (POMA) demonstrated a strong negative correlation (r =-0.74), utilizing a Pearson correlation. Using percent agreement, FRA scores of nine raters yielded 94.74% agreement. Kuder-Richardson (KR)-20 analysis yielded internal consistency of 0.98, 0.97, and 0.98 within subjects scored, indicating high consistency among raters. An intraclass correlation coefficient (Model 3,1) of 0.83 supports intra-rater reliability. History of recurrent falls was the only significant predictor in logistic regression (p = 0.027, odds ratio: 2.83). IMPLICATIONS: Data support use of the FRA in screening for fall-related risk factors in homebound older adults.

VNA HouseCalls of greater Cleveland, Ohio: development and pilot evaluation of a program for high-risk older adults offering primary medical care in the home.

The need for primary medical care in the home will increase with a growing elderly and disabled population. The effectiveness of the service must be assessed in light of its relatively high costs. The aim of this study was to evaluate VNA HouseCalls of Greater Cleveland, Ohio during its first year of operations. The program targets high-risk older adults using teams of advanced practice nurses and physicians. The pilot evaluation focused on the attainment of identified program goals. Data collection techniques included clinical record review (N = 139), mailed referral source satisfaction survey, and both mailed and telephone interview patient satisfaction surveys. The results showed that the typical patient served by VNA HouseCalls was a homebound woman in advanced old age with regular family contact and both physical and mental disorders. When asked, the typical patient indicated that without the program she would not have received the care that she needed.VNA HouseCalls helped in preventing functional decline and reducing hospitalization. It received high satisfaction ratings from both referral sources and patients. Study findings suggest that primary care in the home bears further examination for addressing community need and affecting positive patient outcomes for high risk older adults.

Mobile medical care units: an innovative use of Medicare funding.

Medicare is an underutilized payment source for home-delivered health care services for homebound elderly. An innovative service provision for home health care, Mobile Medical Care Units (MMCU), is presented. MMCU consist of a multidisciplinary team of health care professionals who are responsible for following the health care needs of their elderly patients on a continuous long-term basis across settings. This comprehensive care has significant impacts on homebound elderly and the health care industry. MMCU have the potential to be covered more inclusively by primary or supplemental health insurance plans, including Medicare, Medicaid, and HMO's, or by special funding from state aging departments.

Variation in nutritional risk among Mexican American and non-Mexican American homebound elders who receive home-delivered meals.

Good nutritional health is essential to prevent functional decline and improve quality of life. Little is known of disparities in the extent of risk for poor nutritional health among homebound Mexican American (MA) elders who receive Older American Act Nutrition Program (OAANP) home-delivered meals. In order to assist OAANP service providers in understanding racial/ethnic differences in nutritional risk, this study examined routinely collected data on 908 homebound MA and non-MA in the Texas Lower Rio Grande Valley. Homebound MA were more likely to report poverty, risk factors for and indicators of poor nutritional health. Independent of poverty and covariates,MA were more likely to report very high nutritional risk. This underscores the importance of understanding racial/ethnic disparities in the extent of risk for poor nutritional health for the development, implementation, and evaluation of effective strategies to alleviate nutritional health disparities.

Nutrition risk screening: the interrelationship of food insecurity, food intake, and unintentional weight change among homebound elders.

Nutrition risk screening is a key component of the homedelivered meals program. To examine direct and indirect relationships among individual components of nutrition risk, path analysis was conducted on routinely collected data from 908 homebound elders who received home-delivered meals. The good fit of the model revealed that specific nutrition risk factors and indicators of nutritional risk were directly and indirectly associated with meal frequency and unintended weight change. With the heightened vulnerability for poor nutritional health among homebound elders who report food insecurity, policymakers and service providers should strengthen efforts to target individual components of nutrition risk rather than aggregate scores or categorical measures.

Inadequate intakes of indispensable amino acids among homebound older adults.

Adequate dietary intakes of all indispensable amino acids are vital to optimal health. Using three random 24-hour dietary recalls and the newly released Dietary Reference Intakes (DRIs), we examined the extent and correlates of inadequate dietary intakes of indispensable amino acids among 323 homebound older adults who received home-delivered meals. Despite regular receipt of home-delivered meals and controlling for other sample characteristics, three factors were independent ly associated with usual dietary intake below the Estimated Average Requirement (EAR) for at least one indispensable amino acid-not regularly eating a breakfast meal, having a diminished sense of taste, and consuming less than 65% of total protein from animal sources. With the greater vulnerability for poor nutritional health among homebound older individuals, policymakers and service providers should strengthen efforts to target the type and amount of protein and tailor programs that address a variety of influences on the adequacy of protein intake.

Diuretic medication therapy use and low thiamin intake in homebound older adults.

Diuretic therapy (DT) plays a major role in disease management. However, one issue of concern in nutritionally vulnerable elders is that diuretic therapy also increases thiamin excretion, and little attention has been paid to the linkage between DT use and dietary intake of thiamin in this older population. The purpose of this study was to assess the relationship between DT use and dietary intake of thiamin in a randomly recruited sample of 342 homebound older adults. Baseline data, including three 24-hour recalls, were used to identify thiamin intake from food (15% < EAR and 33% < RDA), DT use (49%), and meal pattern (18% not regularly eating breakfast). Independent of sociodemographic and meal pattern variables, DT users (relative to non-users) were at increased odds for dietary thiamin intake < RDA (OR = 2.3) and < EAR (OR = 4.2). Considering the importance of home-delivered meals as a primary source of food assistance to homebound elders and that thiamin deficiency may exacerbate health problems, the results of this study suggest the need to include information on DT use as an integral component of program assessment for the targeting and monitoring of strategies to alleviate the risk for deficiency.

Participant characteristics predicting voluntary early withdrawal from a multidisciplinary program providing home-delivered meals and dietitian/social work case management to homebound elders.

We examine whether baseline characteristics of participants enrolled in a multidisciplinary program providing home-delivered meals and dietitian/social work case management to homebound seniors predicted voluntary early withdrawal. Sixty-nine participants voluntarily withdrew early and 111 completed the project. Six hypotheses were based on a conceptual framework incorporating (1) agreement between project elements and needs/preferences of individuals and (2) whether participants would improve and no longer require or desire the intervention. Three of the hypotheses were supported by means of logistic regression analysis. Voluntary early withdrawers at baseline: (1) were more mobile, (2) ate less often, and (3) responded that food tastes good less often. The results suggest that carefully considering the interaction of potential participant characteristics and project interventions will improve nutrition project retention.

Gender difference in physical performance, body composition and dietary intake in homebound elders.

Considering that the most vulnerable subgroup of elders for poor nutritional status and functional decline is the increasing number of homebound women, we examined gender differences in physical performance, body composition, and dietary intake in a randomly recruited sample of 345 homebound elders (81% women, 48% black, > 65% income < $750/month). After controlling for demographic and health-related factors, the results from multivariate analyses indicated that women were more likely than men to report the lowest nutrient intake and were 2.9 times more likely to be at the worst level of overall physical performance. These results suggest a heightened vulnerability of homebound older women to poor physical performance, low dietary intake, and increased Body Mass Index (BMI). Prospective research is now needed to examine the interrelationships between physical performance, dietary intake, and body composition among the growing homebound older population.

Appreciating the predicament of housebound older adults with arthritis: portrait of a population.

This paper draws a socio-demographic, physical, psychosocial, and behavioural profile of housebound older adults with arthritis and compares older adults with rheumatoid arthritis to those with osteoarthritis. Data from 125 housebound older adults with osteoarthritis (65 per cent) or rheumatoid arthritis (35 per cent) were compared to published samples and to population data using appropriate weighting. Respondents were mainly women, living alone, mean age 77 years (SD10.50). Symptoms of stiffness, fatigue, and pain intensity were moderate to severe, and a substantial proportion (51.4 per cent) reported depression. Participants reported low levels of health behaviours such as exercise. Overall, older adults with rheumatoid arthritis were significantly younger, reported less pain and limitations, were more optimistic and satisfied with their social life, and had a higher self-efficacy than older adults with osteoarthritis. Home-based pain self-management programs should be constructed considering the unique profiles and needs of this population.

Does delirium need immediate medical referral in a frail, homebound elder?

BACKGROUND AND PURPOSE: This case report describes the clinical decision making process of a physical therapist whose examination of a home bound elderly woman led to a referral for hospitalization. We illustrate how the use of a comprehensive systems screen and thorough examination identified a patient with treatable conditions that required medical care. CASE DESCRIPTION: The patient was a frail 93-year-old woman. She was referred for home-care physical therapy with multiple medical comorbidities and functional decline following a short hospitalization for fall-related injuries. Her function improved after several visits, but upon resuming treatment after a 2- week hiatus, the patient demonstrated major decline in cognitive and physical function. OUTCOMES: The comprehensive systems screen revealed that the patient had increased pallor, loose and frequent bowel movements, urinary incontinence and increased frequency of micturition, confusion and apathy, and extreme fatigue. Her examination showed large declines in scores for Functional Independence Measures, Mini Mental Status Examination, Berg Balance Test, and Timed Up and Go. These results were consistent with indicators for delirium, dehydration, and anemia. The findings were reported to the patient's physician and family members agreed to have the patient evaluated in the local emergency room. CONCLUSIONS: This case report illustrates how knowledge of the pathologies associated with delirium and thorough examination can assist the physical therapist in making clinical decisions when homecare patients require prompt medical referral.

Body fat and cholecalciferol supplementation in elderly homebound individuals.

Vitamin D deficiency, observed mainly in the geriatric population, is responsible for loss of bone mass and increased risk of bone fractures. Currently, recommended doses of cholecalciferol are advised, but since there are few studies evaluating the factors that influence the serum levels of 25-hydroxyvitamin D (25(OH)D) following supplementation, we analyzed the relationship between the increase in serum 25(OH)D after supplementation and body fat. We studied a group of 42 homebound elderly subjects over 65 years old (31 women) in order to assess whether there is a need for adjustment of the doses of cholecalciferol administered to this group according to their adipose mass. Baseline measurements of 25(OH)D, intact parathyroid hormone and bone remodeling markers (osteocalcin and carboxy-terminal fraction of type 1 collagen) were performed. Percent body fat was measured by dual-energy X-ray absorptiometry. The patients were divided into three groups according to their percent body fat index and were treated with cholecalciferol, 7,000 IU a week, for 12 weeks. The increases in serum levels of 25(OH)D were similar for all groups, averaging 7.46 ng/mL (P < 0.05). It is noteworthy that this increase only shifted these patients from the insufficiency category to hypovitaminosis. Peak levels of 25(OH)D were attained after only 6 weeks of treatment. This study demonstrated that adipose tissue mass does not influence the elevation of 25(OH)D levels following vitamin D supplementation, suggesting that there is no need to adjust vitamin D dose according to body fat in elderly homebound individuals.

Health characteristics of elderly Japanese requiring care at home.

The number of elderly subjects requiring care is rapidly increasing, however, their health status has not been well studied. The purposes of this study were to describe the health characteristics of the elderly at home who were using long-term care insurance, and to clarify factors that influence dependence for activities of daily living (ADL). The subjects were 194 elderly people living at home, who were approved for care. The items surveyed were the demographic characteristics, care level (or level of dependence for ADL), Barthel index, grip strength, thigh muscle volume, cognitive impairment using the mini-mental state examination (MMSE), depressed mood using the geriatric depression scale (GDS-15), and serum albumin and hemoglobin levels. The grip strength (p=0.0001), thigh muscle volume (p=0.0030), MMSE score (p=< 0.0001) and serum albumin level (p= < 0.0001) decreased, while the GDS-15 score (p=0.0142) increased with deteriorating care levels. The proportion of subjects not requiring assistance for the items "bathing" and "stair-climbing" in the Barthel index was markedly low in the subjects belonging to the relatively low (mild) care levels. The logistic regression analysis showed that factors associated with dependence for "bathing" and "stair-climbing" were the use of day-services, male sex, decline of grip strength, and a high GDS-15 score. In conclusion, it is important to strengthen the muscles of the upper half of the body, and to correct depressed moods for maintaining levels of ADL in the elderly requiring care at home.

Worry among Canadian seniors.

One hundred mobile and homebound elderly (65+) participants from Fredericton, New Brunswick, Canada were administered Wisocki's Worry Scale, a thirty-five-item questionnaire relating to concerns about finances, health, and social conditions, and requested to self-monitor their worry behavior over a three-day period. Seniors were found to be relatively worry-free. Nevertheless, significant correlations were found between the Worry Scale and measures of mental and physical health. Self-monitoring by seniors provided a more direct validation of the Worry Scale. Results were comparable to those found in the literature with samples from the United States.

[Compliance and knowledge about prescribed medication among elderly home-care recipients by method of providing medications].

After long-term care insurance commenced in April 2000, various types of in-home care began, including delivery of prescriptions medicines to the elderly. However, the effects of in-home care workers on patient drug compliance are unclear as yet. In this study, we examined the characteristics of the care workers who delivered prescription medicines to the elderly, and analyzed the effects on patient drug compliance and knowledge about medication. The subjects included 163 homecare recipients aged 60 and older, who were taking more than one prescribed drug, who ranked worse than J-2 who were physically disabled, and cognitively normal. The rate of good compliance was 71.1% when pharmacists provided the prescribed drugs and counseled the patients at home, which rate was significantly higher than that of self-supply by the patient (35.0%), caregiver supply (44.7%), and home-helper supply (0.0%). The difference in compliance may be explained by the possibility that when caregivers and home-helpers provided prescribed medications, thorough and accurate information about the drugs were not clearly imparted to the elderly, whereas when pharmacists provided prescribed medications, a pharmacological examination was performed and thorough and accurate information was communicated to the elderly. In the group counseled by pharmacists, knowledge about the effects and purpose of medication positively correlated with drug compliance. However, in the group provided drugs by caregivers, knowledge about the effects and purpose of medication inversely correlated with drug compliance. These findings suggested that the elderly in the latter group chose, to some degree, not to comply. Many elderly people had difficulty getting to hospital, and 23.1% of the patients in this study had not consulted the doctor for more than 2 months. Our data suggest that drugs provided by pharmacists and the availability of pharmacist counseling play an important role in preventing drug noncompliance and in making home care more effective, and also suggest that it is important for pharmacists to cooperate with other care workers, including a care-manager, and to provide written information on prescription medicine to caregivers and home-helpers as well as to elderly patients.
