Effects of footwear on measurements of balance and gait in women between the ages of 65 and 93 years.
(49/2563)
BACKGROUND AND PURPOSE: Footwear is not consistently standardized in the administration of the Functional Reach Test (FRT), Timed Up & Go Test (TUG), and 10-Meter Walk Test (TMW). This study was conducted to determine whether footwear affected performance on these tests in older women. SUBJECTS: Thirty-five women, aged 65 to 93 years, were recruited from assisted living facilities and retirement communities. METHODS: Each subject performed the FRT, TUG, and TMW wearing walking shoes, wearing dress shoes, and barefooted. Because of space constraints at the facilities where the testing was performed, 22 subjects performed the FRT and TUG on a linoleum floor and 13 subjects performed the tests on a firm, low-pile, carpeted floor. All 35 subjects completed the TMW on a firm, low-pile, carpeted floor. One-way repeated-measures analyses of variance (ANOVAs) and a Tukey Honestly Significant Difference test were used to compare the outcomes for the 3 footwear conditions, with separate ANOVAs conducted for the different floor surfaces for the FRT and TUG. RESULTS: Subjects performed better on the FRT when barefooted or wearing walking shoes compared with when they wore dress shoes, regardless of floor surface. Differences were found among all footwear conditions for the TUG performed on the linoleum floor and for the TMW. For these tests, the women moved fastest in walking shoes, slower barefooted, and slowest wearing dress shoes. CONCLUSION AND DISCUSSION: Footwear should be documented and should remain constant from one test occasion to another when the FRT, TUG, and TMW are used in the clinic and in research. Footwear intervention may improve performance of balance and gait tasks in older women. (+info)
Who is enrolled in for-profit vs. nonprofit Medicare HMOs?
(50/2563)
We compare the characteristics of enrollees in for-profit and nonprofit Medicare health plans using nationwide data from the 1996 Medicare Current Beneficiary Survey. We find few differences in overall health status, limitations in activities of daily living (ADLs), or history of chronic disease. However, older Americans enrolled in for-profit plans are substantially poorer and less educated than those enrolled in nonprofit plans, are more likely to have joined their plan recently, and are more likely to have joined a plan with the expectation of reducing their out-of-pocket health care costs.

The Dutch pressure sore assessment score or the Norton scale for identifying at-risk nursing home patients?
(51/2563)
OBJECTIVE: To investigate the usefulness of a Dutch pressure sore risk assessment scale--the Centraal Begeleidingsorgaan voor de Intercollegiale Toetsing (CBO; National Organization for Quality Assurance in Hospitals) score--in the detection of patients at risk of developing pressure sores after admission to a nursing home. As the Norton score is the standard method of risk assessment, we also investigated which score (Norton or CBO) has the stronger relationship to the development of pressure sores. DESIGN: Longitudinal cohort design. PATIENTS: 220 nursing home patients, 80 men, 140 women, mean age 79 years (standard deviation 3). MEASURES: Admission assessments for the presence of pressure sores, CBO and Norton scores, preventive measures and demographic characteristics. We made observations every week for 4 weeks. MAIN OUTCOME MEASURE: Presence or absence of pressure sores. MAIN RESULTS: 54 patients (25%) developed a pressure sore. A significant, nonlinear relationship was found between the CBO score on admission and the development of pressure ulcers for the first 2 weeks after admission. Multiple logistic regression analysis showed that only mobility (odds ratio = 3.6, P = 0.0001) and mental state (odds ratio = 2.0, P = 0.03) showed a significant relationship with the development of pressure ulcers. The CBO score was no better in risk assessment than the Norton score. CONCLUSIONS: The CBO score can be used for assessment of the risk of developing pressure ulcers in the first 2 weeks after admission to a nursing home, but is no better than the Norton score. Since the Norton score is easier to use, it is slightly preferable for use in this setting. However, neither score is a good indicator of patients at risk. Physicians should not depend solely on risk scores when prescribing preventive measures. (+info)
Do older hospital patients recognize adverse drug reactions?
(52/2563)
OBJECTIVE: To establish the relationship between subjective complaints of side effects of drugs and the objective presence of adverse drug reactions in older patients. DESIGN: Observational cross-sectional study. SETTING: Five medical wards at the University Hospital Rotterdam Dijkzigt. SUBJECTS: Patients aged 70 and over admitted to the general medical wards over a 3-month period. METHODS: Statistical comparison and Kramer's algorithm. RESULTS: Of 106 patients, 102 used medication, and 93 of these were able to report whether they believed they were experiencing drug side effects. Thirty-six [39% (95% confidence interval 28.8-48.6)] believed that they were experiencing side effects and the number of diagnoses per patient and the proportion of patients with chronic obstructive pulmonary disease was higher in these 36 'complainers' than in the group of the 'non-complainers'. We found a correct opinion (true positive and negative) about the objective presence or absence of mild or severe adverse drug reactions in 79% (95% confidence interval 70.2-86.8). Asking the patient about side effects of drugs had a sensitivity of 0.70 and a specificity of 0.85 patients. The severe adverse drug reactions in 21 patients were not recognized by 14 of them. CONCLUSION: At hospital admission, older patients should be asked about drug side effects because they are often correct in recognizing them. However, severe adverse drug reactions are not easily recognized. (+info)
Myasthenia gravis and recurrent falls in an elderly patient.

PRESENTATION: An elderly man had recurrent hospital admissions with falls. OUTCOME: Acetylcholine receptor antibodies and single-fibre electromyogram were useful in the diagnosis of myasthenia gravis. Treatment prevented further hospital admissions. (+info)
Effects on mortality of getting the basic health examination under the Health Services for the Elderly Act and modification of the effects by health status among elderly persons in a rural community.
(54/2563)
This longitudinal study examines the effect on mortality of regular use of the basic health examination under the Health Services for the Elderly Act and heterogeneity of the effect according to levels of physical and mental health status among community dwelling elderly persons. Of persons aged 65 and older who lived in Otsuki town, Kochi prefecture, and completed a questionnaire survey about health in February 1991, 1,470 survivors on the anniversary of the baseline survey were followed by the end of March 1996. Regularity of getting the examination was determined by the history of use of the examination in 1990 and 1991. Mortality reduction associated with annual use of the examination was observed in both the 65-74 and the 75 and older age groups and the benefit got smaller with advancing in age. In the 75 and older age group, the benefit from annual use of the examination was restricted to persons having no impairment in physical activities of daily living and those having favorable mental health. Biennial use of the examination was associated with the same amount of mortality reduction as annual use among persons having chronic conditions under treatment in the 65-74 age group. Regular use of the basic health examination at old ages is effective and the effectiveness varies by age range and level of functional health status. (+info)
Randomized controlled trial of exercise training for older people (Sendai Silver Center Trial; SSCT): study design and primary outcome.
(55/2563)
Physical exercise is expected to improve and maintain physical function in older people, thus promoting health and preventing or postponing the onset of disability in later life. The Sendai Silver Center Trial (SSCT) was a randomized controlled trial designed to evaluate the efficacy of exercise training among healthy free-living older people. Sixty-five eligible participants, aged from 60 to 81 years, were randomly allocated to an exercise group or a control group. The subjects in the exercise group were asked to attend training classes at the Sendai Silver Center, a municipal health and welfare facility in the center of Sendai City, at least twice a week for 25 weeks. Each training class, lasting two hours, started with a warm-up session, followed by an endurance session with a bicycle ergometer, and a resistance exercise training session using rubber films, and ended with a cool-down session. The subjects in the control group were asked to attend recreational classes at the Center twice a month. There were no drop-outs or accidents during the intervention. Comparison of maximum oxygen consumption (VO2max) before and after the 25-week intervention revealed a significant increase in the exercise group (2.1 ml/kg/min) but no significant change in the control group. Our result is equivalent to the participants becoming younger in aerobic capacity by five years after six months of exercise training. (+info)
Effect of preventive home visits by a nurse on the outcomes of frail elderly people in the community: a randomized controlled trial.
(56/2563)
BACKGROUND: Timely recognition and prevention of health problems among elderly people have been shown to improve their health. In this randomized controlled trial the authors examined the impact of preventive home visits by a nurse compared with usual care on the outcomes of frail elderly people living in the community. METHODS: A screening questionnaire identified eligible participants (those aged 70 years or more at risk of sudden deterioration in health). Those randomly assigned to the visiting nurse group were assessed and followed up in their homes for 14 months. The primary outcome measure was the combined rate of deaths and admissions to an institution, and the secondary outcome measure the rate of health services utilization, during the 14 months; these rates were determined through a medical chart audit by a research nurse who was blind to group allocation. RESULTS: The questionnaire was mailed to 415 elderly people, of whom 369 (88.9%) responded. Of these, 198 (53.7%) were eligible, and 142 consented to participate and were randomly assigned to either the visiting nurse group (73) or the usual care group (69). The combined rate of deaths and admissions to an institution was 10.0% in the visiting nurse group and 5.8% in the usual care group (p = 0.52). The rate of health services utilization did not differ significantly between the 2 groups. Influenza and pneumonia vaccination rates were significantly higher in the visiting nurse group (90.1% and 81.9%) than in the usual care group (53.0% and 0%) (p < 0.001). INTERPRETATION: The trial failed to show any effect of a visiting nurse other than vastly improved vaccination coverage. (+info)
