Functional decline of the elderly in a nursing home.

INTRODUCTION: This study aims to determine if risk factors present on admission to the nursing home could be predictive of later functional decline and to determine the causes of decline. METHODS: This is a retrospective case-control study conducted in 2000 at a voluntary welfare nursing home. Functional decline was defined as deterioration in two or more of the five activities of daily living (ADLs), namely: mobility, toileting, bathing, dressing and feeding, from the time of admission to the study period. Potential risk factors for decline studied were: age, sex, marital status, number of medical diagnoses and medications, types of medical diagnoses, and the presence of dementia on admission to the home. Causes of decline were categorised as (A) Development of new illness, (B) Progression of chronic illness, or (C) Both of the above. RESULTS: 36 out of 103 residents had functional decline. On analysis, univariate and multivariable logistic regression models, adjusted for length of stay, yielded the same significant risk factors for decline, namely: age (p-value is 0.02) and dementia (p-value is 0.04). Majority of decline (78 percent) was due to progression of chronic illnesses, most commonly dementia (15 out of 36), eight percent were due to acute illness (stroke), and 14 percent were due to both. In January 2003, 18 out of the 36 residents who declined had died. CONCLUSIONS: Functional decline is common in the nursing home. More attention should be paid to the older residents and those with dementia, right from the point of admission.

Who are the residents of a nursing home in Singapore?

AIM OF STUDY: To describe the residents of a nursing home for the elderly in terms of their socio-demographic profile, mental and physical attributes, functional abilities and existing medical problems. METHOD: A random sample of 120 subjects was obtained from a total of 350 residents in a voluntary welfare nursing home. Two subjects were excluded as they did not satisfy inclusion criteria (age > or = 60 years). The subjects' biodata, social background, medical problems and functional status at the time of admission were obtained by a review of the case records. Each of the subjects was examined with attention to their general condition, hearing and vision, presence of postural hypotension, cognition and ability to perform basic activities of daily living (ADL). RESULTS: Results were available for 106 out of the 118 subjects as the rest were either discharged in the course of the study or had died. Single (36%), widowed (41%), female (71%) and age > or = 75 years (73%) consisted the majority. Most subjects (43%) were admitted because of both medical and social factors. Twenty-two percent appeared undernourished and of those who could be assessed, 14% had postural hypotension, 18% were hearing impaired and 53% had visual impairment. Fifty-two per cent suffered from mental problems while 46% and 40% had been diagnosed with hypertension and stroke respectively. Forty-eight percent had probable cognitive impairment (according to ECAQ scores) and 41% were very severely disabled (according to Barthel Index). Fifty-five percent were dependent in bathing, 50% dependent in dressing, 50% incontinent of urine (and requiring diapers), 48% were non-ambulant and 21% dependent in feeding. CONCLUSION: With a significant proportion of the population requiring nursing home care in the future, a closer review of the situation is needed. This study has identified malnutrition, urinary incontinence, falls, functional decline and impaired vision/hearing as issues that deserve greater attention and, where necessary, intervention. Whether implementing recognised effective interventions will truly benefit our nursing home residents would warrant more local studies.

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.

Predictive factors of post-discharge mortality in the hospitalised elderly.

AIM: To study the death rate of noninstitutionalised elderly after discharge from hospital, describe the causes of death and identify predictive factors of mortality. METHODS: Vital status and cause of death of patients was ascertained by linkage to the death registry I year post discharge. Age, sex, race, marital status, housing and class of ward (to reflect socioeconomic status), presence of carer, Elderly Cognitive Assessment Questionnaire (ECAQ) score, Barthel score, presence of depression, number of chronic illnesses and length of stay in the hospital were studied as potential predictive factors for mortality using Cox proportional hazard regression models. RESULTS: Death occurred in 38 out of 113 patients. The commonest causes of death were malignancy (18%) and cerebrovascular disease (18%). Barthel score and length of stay were independent significant predictive factors of mortality. Elderly with low ECAQ score, with carers and from C class wards also had higher mortality although these results were not statistically significant. CONCLUSION: Post-discharge mortality is high in the elderly. We recommend that further studies be done to determine if amelioration of these predictive factors would lead to decreased mortality or improvement of quality of life.

Perceived need for community geriatric services: a survey at a regional hospital in Singapore in an inpatient setting.

Our primary aim was to study the need for community services as perceived by the elderly and their relatives. A secondary objective was to determine the predictive factors of need for these services. This is a survey of 115 consecutive non-institutionalised patients admitted to a hospital geriatric department and their relatives. Twenty-seven elderly patients without cognitive impairment and 115 relatives were interviewed as to their need for community services after discharge. Services most needed by patients were: 24-hour medical helpline (33%), emergency alarm system (19%), social helpline (14%) and day care centre (13%). Services most needed by relatives were: 24-hour medical helpline (70%), emergency alarm system (40%), home visits by doctors (40%), respite care (35%), day care centre (35%) and transport service (33%). There were low levels of need for home help service, meal delivery service and the befriender service. Important predictive factors of need were: low ECAQ (Elderly Cognitive Assessment Questionnaire) score, low Barthel score, and absence of a carer. The development of community geriatric services in Singapore should be guided by the perceived needs of the elderly and their relatives/care-givers. This study is limited by its hospital-based perspective and small numbers. We recommend that further community-based studies be carried out to complement our study and extend our findings.
