Nursing home falls: a local perspective.

INTRODUCTION: This study aims to examine the demography of falls, factors that contribute to falls and fall risk factors in residents of a nursing home for the elderly in Singapore. MATERIALS AND METHODS: An 18-month follow-up study was carried out on 95 nursing home residents. Information on the subjects' potential risk factors for falls was obtained through a review of their casenotes and physical examination. At the end of the study period, the casenotes were reviewed for any documented fall, the circumstances surrounding each fall and whether complications resulted from the fall. The likely factors and events associated with each fall were categorised where possible. Logistic regression was performed to determine the risk factors for falls. Subjects who died or were discharged during the study were included in the analysis. RESULTS: Several subjects (72.6%) were > or = 75 years old, required assistance in activities of daily living (71.6%), cognitively impaired (52.6%), diagnosed with mental illness (49.5%) and non-ambulant (43.2%). A total of 63 falls contributed by 38 (40%) subjects were documented over 18 months, giving an incidence of 0.5 fall per bed year. Thirteen (20.6%) injuries resulted from the falls, of which 3 were fractures. Falls associated with both intrinsic and extrinsic factors were identified in 38.1% of falls. The most common intrinsic factors were gait disorders (31.7%) and confusion/difficult behaviour (31.7%). Contributory extrinsic factors include wheelchair/commode (22.2%) and bathroom-related (15.9%) incidents. Most falls occurred during ambulation (31.7%) and transfers (17.5%). On multivariate logistic regression, the only significant risk factors for falls were "need for ambulatory aids" (odds ratio, 24.4) and "cognitive impairment" (odds ratio, 8.1). CONCLUSION: The study confirms that falls are common amongst elderly in a local nursing home. Residents with gait instability and behavioural problems due to underlying dementia or mental illnesses are most at risk. Extrinsic factors, such as bathroom activities and the use of wheelchair/commodes, are contributory. Thus, falls reduction protocols in nursing homes should include behavioural measures, enhanced care practices and environmental modifications to be effective.

Urinary incontinence: an ignored problem in elderly patients.

Urinary incontinence is a common problem among the elderly, especially those admitted to acute care hospitals. A study investigating this problem was conduced in the geriatric wards of the Tuen Mun Hospital, Tuen Mun, from 26 October 1995 to 9 November 1995. Fifty of 139 (36%) patients had urinary incontinence with a male to female ratio of 1:15. Patients with urinary incontinence were found more often to have mobility problems and a higher institutionalisation rate than did continent patients. Dementia and cerebrovascular accident were also found to be associated with this problem. Although it is a common problem, none had been evaluated or treated before. Most of the caregivers thought that urinary incontinence was a normal ageing process and used diapers to treat this problem.

A survey of the long term outcome of elderly stroke survivors and the needs of their carers.

A survey was conducted to assess the long term outcome of 60 elderly stroke survivors (mean age, 81.7 years). Of these patients, 48% died within one year of discharge and 79% of the mortality occurred in the first six months. Patients discharged to institutions after the initial stroke had a significantly higher risk of death in one year (relative risk=1.47) compared with those who were discharged home. For those who survived for a mean period of 18.6months, 72% (21/29) were institutionalised. This group had significantly worse functional status and mobility compared with those who were living at home. The caring of elderly stroke patients was considered a heavy burden for most carers at home or in institutions and the need for medical and social support was great.

The prevalence of diabetes mellitus and an assessment of methods of detection among a community of elderly Chinese in Hong Kong.

This study provides information on the prevalence of diabetes mellitus in a group of elderly Chinese subjects aged 60 and above living in the community in Hong Kong, and investigates the sensitivity of the urine sugar, random blood glucose, glycosylated haemoglobin, and fructosamine measurements compared to a glucose tolerance test in screening for diabetes mellitus in this population. Four hundred twenty-seven subjects aged 60 and above were studied. The National Diabetes Data Group Criteria were used for the diagnosis of diabetes. Those with a random blood glucose exceeding 12.5 mmol/l were considered diabetic, and all of these patients had glycosuria together with elevated total glycosylated haemoglobin and fructosamine concentrations. A diagnostic 75 g oral glucose tolerance test was performed on patients with one or more of the following abnormalities: glycosuria, random plasma blood glucose 7.8 mmol/l to 12.5 mmol/l, glycosylated haemoglobin 8.5%, and fructosamine 2.20 mmol/l. By these criteria, the prevalence of diabetes in this community was found to be 9.8%. An elevated random glucose greater than 11.1 mmol/l proved to be the only specific method of screening and glycosuria was found to be at least as good as fructosamine and HbA1. However, HbA1 is more sensitive than random glucose, glycosuria or fructosamine in detecting impaired glucose tolerance. On the basis of this study, a higher reference range for glycosylated haemoglobin for the elderly alone is also suggested (5.74-9.34%).
