Outcomes of routine testing of liver enzymes in institutionalized geriatric patients.
(1/302)
This study sought to identify any benefit of routine liver function tests (LFTs) in chronically ill, geriatric patients and to assess which patients require evaluation for abnormal LFT levels. A retrospective chart review was carried out on 268 consecutive patients (M:F = 1.2, mean age 77 years, range 61-98 years) presenting for acute care from a long-term care facility. All were without jaundice, right upper quadrant pain, pruritus, bruising, or signs of chronic liver disease. The degree of LFT abnormality (aspartate aminotransferase, alanine aminotransferase, total bilirubin, or alkaline phosphatase) during admission was compared to the clinical diagnosis at the time of discharge. The most common diagnoses were pneumonia, urinary tract infection, and peripheral or coronary disease in 186 (60%). Thirty-seven patients (14%) had elevated LFT levels on admission. The levels normalized within 2 days in 26 of these patients, 25 of whom had a history of vascular disease (96%). Of the 11 remaining patients, 4 had coexistent vascular disease (36%), and 5 had LFT levels twice normal (none with vascular disease) and underwent abdominal ultrasound. One patient had a common bile duct stone successfully extracted. Enzyme abnormalities were due to hepatitis B or medication use in 10 of 11 patients. No patient had liver biopsy. All but one of the 268 patients were discharged without further evaluation. Over one year of follow up, no patient returned for a liver-related problem. Based on these findings, only those patients with LFT levels that are twice normal and which do not normalize within 2 days warrant further evaluation. Transient LFT abnormalities may be due to decreased liver perfusion. (+info)
Profile of disability in elderly people: estimates from a longitudinal population study.
(2/302)
OBJECTIVES: To provide estimates of the numbers of cognitively impaired and physically disabled elderly people in England and Wales, subdivided by a range of sociodemographic, dependency, care receipt, and survival variables, to support debates on the form and funding of health and welfare programmes. DESIGN: Interviews at baseline and 2 year follow up plus data on resource use extracted from records for those with disability. SUBJECTS: 10 377 people aged 65 years and over in Cambridgeshire, Newcastle, Nottingham, and Oxford. All estimates weighted to population of England and Wales in 1996. RESULTS: 11% of men and 19% of women aged 65 and over were disabled, totalling 1.3 million people; 38% of these were aged 85 or over and a similar percentage were cognitively impaired. Overall, more than 80% of elderly disabled people needed help on at least a daily basis. Over a third of people with limitations to daily activity living in private households were wholly or partly dependent on formal services for help. 63% of disabled elderly people used acute hospitals during the 2 year follow up, 43% as inpatients. 53% of those with cognitive impairment and limitations to daily activity were living in institutions. CONCLUSIONS: Very elderly people and those with cognitive impairment make up a large proportion of those in need of long term care. A large proportion of even the most disabled elderly people currently live outside institutions and depend on formal services as well as informal care givers. Disabled elderly people use acute hospitals extensively, underlining the interrelations between acute and long term care. (+info)
The prognosis of falls in elderly people living at home.
(3/302)
BACKGROUND: there are few longitudinal studies of the prognosis of falling at home. OBJECTIVE: to determine outcomes in older people who fall once and more than once. DESIGN: longitudinal prospective cohort study. SETTING: primary care in the UK. SUBJECTS: 1815 subjects over 75 who had a standardized and validated health check. METHOD: annual interviews over 4 years. Practice records were used to establish death and admission to institutions. RESULTS: risk of death was increased at 1 year [odds ratio (OR) 2.6, 95% confidence interval (CI) 1.4-4.7] and 3 years (OR 1.9, 95% CI 1.2-3.0) for recurrent fallers but not single fallers (OR 0.9, 95% CI 0.5-1.6 at 1 year; OR 0.97, 95% CI 0.7-1.4 at 3 years). Risk of admission to long-term care over 1 year was markedly increased both for single fallers (OR 3.8, 95% CI 1.8-8.3) and recurrent fallers (OR 4.5, 95% CI 1.7-12). Functional decline was not related to faller status, the latter being very variable from one year to the next. CONCLUSIONS: the stronger relationship between falling and admission to long-term care rather than mortality supports the hypothesis that the perceived risks for those who fall only once are exaggerated.

Residential status and risk of hip fracture.
(4/302)
OBJECTIVE: to examine the association between residential status and risk of hip fracture in older people. DESIGN: population-based case-control study. SETTING: Auckland, New Zealand. SUBJECTS: a random sample of all individuals > or = 60 years, hospitalized with a fracture of the proximal femur between July 1991 and February 1994. Controls were age and gender frequency-matched to the cases, randomly selected from a random sample of general practitioners. MAIN OUTCOME MEASURES: radiographically-confirmed fracture of the proximal femur. Fractures sustained as a result of major trauma, such as in a motor vehicle crash, and those associated with pre-existing pathological conditions were excluded. RESULTS: individuals living in institutions were almost four times more likely to sustain a hip fracture [age- and gender-adjusted odds ratio (OR)=3.8; 95% confidence interval (CI): 3.0-4.8] than those living in private homes. After adjustment for potential confounding factors, the risk of hip fracture associated with living in an institution remained significantly increased (P< 0.0001), although the magnitude of the risk was somewhat diminished (OR=2.2; 95% (CI: 1.5-3.5). CONCLUSIONS: living in an institution is associated with an increased risk of hip fracture in older people. Specific factors that place these individuals at increased risk need to be identified, in order to develop intervention strategies. (+info)
Validity and reliability of the Medical Outcomes Study Short Form-20 questionnaire as a measure of quality of life in elderly people living at home.
(5/302)
BACKGROUND: the Medical Outcomes Study Short Form-20 (SF-20) questionnaire is recommended for health-related quality of life research, but there is little information on its utility in older people. We assessed the validity, reliability and feasibility of using the SF-20 in an elderly community-dwelling population. METHODS: the SF-20 was administered to a stratified, random sample of 333 elderly subjects. FINDINGS: assessment of content validity revealed that important domains were lacking, while others appeared to be inappropriately combined. Using Spearman correlation coefficients, the SF-20 had acceptable convergent and discriminant validity. A principal components analysis provided evidence for internal consistency for some of the subscales. Evidence for test-retest reliability was good. INTERPRETATION: while the reliability and feasibility of the SF-20 appear satisfactory, concerns about validity and responsiveness should temper enthusiasm for its use with elderly people living at home.

Amoebiasis among institutionalized psychiatric patients in Taiwan.
(6/302)
Although information on amoebiasis among institutionalized psychiatric patients is available, reports on the relationship between behaviour and this infection are not abundant. From July 1995 to June 1996, stool and blood samples were collected from 565 patients in three psychiatric hospitals of North Taiwan. Stool samples were examined using the direct smear and formalin-ethyl acetate sedimentation techniques as well as ProSpecT Entamoeba histolytica Microplate Assay kit. Blood samples were examined by the Amebiasis Serology Microwell ELISA kit. Among these patients, 14 (2.5%) harboured one or two species of intestinal parasites. There were 6 (1.1%) E. histolytica/E. dispar cyst passers: 5 positive in stool ELISA test and 2 with antibodies against E. histolytica. Among demographic factors, type of psychiatric disorder and disability, only a significant sexual difference in seropositivity of E. histolytica was observed. These findings indicate that the infected patients acquired the infections before they entered the hospitals. (+info)
Multifaceted shared care intervention for late life depression in residential care: randomised controlled trial.
(7/302)
OBJECTIVE: To evaluate the effectiveness of a population based, multifaceted shared care intervention for late life depression in residential care. DESIGN: Randomised controlled trial, with control and intervention groups studied one after the other and blind follow up after 9.5 months. SETTING: Population of residential facility in Sydney living in self care units and hostels. PARTICIPANTS: 220 depressed residents aged >/=65 without severe cognitive impairment. INTERVENTION: The shared care intervention included: (a) multidisciplinary consultation and collaboration, (b) training of general practitioners and carers in detection and management of depression, and (c) depression related health education and activity programmes for residents. The control group received routine care. MAIN OUTCOME MEASURE: Geriatric depression scale. RESULTS: Intention to treat analysis was used. There was significantly more movement to "less depressed" levels of depression at follow up in the intervention than control group (Mantel-Haenszel stratification test, P=0.0125). Multiple linear regression analysis found a significant intervention effect after controlling for possible confounders, with the intervention group showing an average improvement of 1.87 points on the geriatric depression scale compared with the control group (95% confidence interval 0.76 to 2.97, P=0.0011). CONCLUSIONS: The outcome of depression among elderly people in residential care can be improved by multidisciplinary collaboration, by enhancing the clinical skills of general practitioners and care staff, and by providing depression related health education and activity programmes for residents.

Transmission of a multidrug-resistant Mycobacterium tuberculosis strain resembling "strain W" among noninstitutionalized, human immunodeficiency virus-seronegative patients.
(8/302)
Since 1990, several outbreaks of multidrug-resistant tuberculosis (MDR-TB) have been described among institutionalized patients infected with human immunodeficiency virus (HIV). We describe a community MDR-TB outbreak among HIV-seronegative patients in Cape Town, South Africa. Isolates were characterized by restriction fragment length polymorphism (RFLP) analysis and dot-blot hybridization analysis of mutations conferring resistance for isoniazid, rifampin, streptomycin, and ethambutol. All isolates were identical on RFLP analysis. In 2 patients, RFLP analysis showed exogenous reinfection during or after treatment for drug-susceptible TB. Mutation analysis confirmed the genotypic identity of the isolates. The infecting strain was genotypically related to strain W, which is responsible for the majority of MDR-TB outbreaks in New York City. Transmission of MDR-TB is thus not limited to HIV-seropositive patients in an institutional setting but occurs within a community. (+info)
