Accidental falls among community-dwelling older adults: improving the identification process of persons at risk by nursing staff.

Elderly persons living in the community are a heterogeneous population. Among them, the screening of persons at risk of falling is still a matter of debate. The aim of this analysis was to improve the identification process of elderly persons living in the community at risk for falling by nursing staff of community- based services. A secondary analysis was performed with the data from a prospective non-randomized interventional trial. The study included 268 community-dwelling older adults (mean age of 82 years, 81.3% female) from Ulm and Neu-Ulm with a followup period of 12 months. Fall risk indicators were extracted from the nursing assessment and analysis with crude odds ratios revealed the following risk indicators for falls: assistance when transferring, bathing and climbing a flight of stairs as well as fall history. Afterwards, fall risk indicators were selected by backward elimination in a multiple logistic regression. Variable selection identified a positive fall history and the need for assistance when bathing as important risk indicators. These two risk indicators could be used as a screening tool, which would be easy to perform by nursing staff in their daily work. This screening test defined as more than one fall in the last 12 months or bathing assistance, the first ADL to be affected in the disablement process, has a sensitivity of 85.3% and a specificity of 42.1%.

An algorithm to screen long-term care residents at risk for accidental falls.

BACKGROUND AND AIMS: The process applied to identify fall risks in frail elderly persons remains a matter of debate. We intended to develop a fall screening instrument for clinically defined subgroups of long-term care residents, to be administered by nursing staff. METHODS: Fall risk indicators were selected by multiple logistic regression in three pre-defined subgroups. The first consisted of residents who were not able to transfer, defined as a change from sit-to-stand position, without physical assistance (NAT). The second subgroup comprised residents who were able to transfer, but who had had a recent fall during the last 6 months (AT-F). Residents who were able to transfer but had had no recent fall (AT-NF) were in the third subgroup. The prospective observational study included 472 long-stay residents (mean age 84 years, 79% female) from three community nursing homes, with a follow-up period of 12 months. RESULTS: Fall incidence was highest in the AT-F subgroup: 6066 per 1000 resident years. The risk indicators identified included a positive fall history and restraint use in the NAT group, transfer assistance in the AT-F group, and urinary incontinence and visual impairment in the AT-NF group. CONCLUSIONS: The identification of different risk indicators in the subgroups indicates that specific strategies may be more appropriate to improve the effectiveness of fall prevention in long-term care, than the application of one strategy to all residents. The identification of incontinence, visual impairment, and restraints as risk indicators stresses the need for intervention studies which specifically address these items.

Pharmacological treatments for persistent non-malignant pain in older persons.

Persistent non-malignant pain is common, often neglected and under-treated among older persons. Some older adults do not complain because they consider chronic pain to be a characteristic of normal aging. Physicians have concerns regarding adverse effects of pharmacological treatment. The model of the World Health Organization for treatment of cancer pain is generally accepted and also recommended for persistent non-cancer pain. Furthermore, non-pharmacological treatment should complement drug treatment whenever possible. An initial assessment and possible treatment of underlying causes of pain are pertinent. Modern pharmacological pain management is based on non-opioid and opioid analgesics. NSAIDs are among the most widely prescribed class of drugs in the world. The new cyclo-oxygenase-2 inhibitors such as celecoxib and rofecoxib offer an alternative for the treatment of mild-to-moderate pain in patients with a history of gastric ulcers or bleeding. Paracetamol (acetaminophen) is being used widely for the management of mild pain across all age groups as it has moderate adverse effects at therapeutic dosages. For moderate pain, a combination of non-opioid analgesics and opioid analgesics with moderate pain relief properties (e.g. oxycodone, codeine, tramadol and tilidine/naloxone) is recommended. For severe pain, a combination of non-opioid analgesics and opioid analgesics with strong pain relief properties (e.g. morphine, codeine) is recommended. The least toxic means of achieving systemic pain relief should be used. For continuous pain, sustained-release analgesic preparations are recommended. Drugs should be given on a fixed time schedule, and possible adverse effects and interactions should be carefully monitored. Adjuvant drugs, such as antidepressants or anticonvulsants, can be very effective especially in the treatment of certain types of pain, such as in diabetic neuropathy. Effective pain management should result in decreased pain, increased function and improvement in mood and sleep.

Measuring power during the sit-to-stand transfer.

Power has been demonstrated to be an early and potent marker of frailty. The measurements currently available are tied to locality. Usually, measurements include single joint movements or movements of only the legs and the resistance is not adjusted for body weight. In this study, a portable method to measure power in the sit-to-stand transfer was developed and tested. Mean power was calculated from the vertical ground reaction force of body weight, the difference between height in a sitting and in an upright position and the time taken to stand up. The results of this power measurement were compared with an isokinetic force measurement, the "Nottingham power rig", and measurement of physical performance in a five-repetition chair rise (five-chair rise). A convenience sample of 33 healthy elderly subjects [mean (SD) age: 67.8 (6.7) years; 17 men, 16 women] was included. Measurement of power during the sit-to-stand transfer showed good correlation to isokinetic force measurement (r=0.68) and to the "Nottingham power rig" (r=0.6). Correlation to five-chair rise was poor (r=-0.08). In conclusion, the study shows that the method presented is able to measure power during performance of a daily task. The poor correlation between the introduced measurement and the five-chair rise suggests that it might be able to detect decline in muscle function earlier by the introduced measurement than by measurement of the functional status. As it is inexpensive and portable, its use in clinical practice and research contexts, including home-bound individuals, is feasible.

Preventing falls in community-dwelling frail older people using a home intervention team (HIT): results from the randomized Falls-HIT trial.

OBJECTIVES: To evaluate the effect of an intervention by a multidisciplinary team to reduce falls in older people's homes. DESIGN: Randomized, controlled trial with follow-up of subjects for 1 year. SETTING: University-affiliated geriatric hospital and older patients' homes. PARTICIPANTS: Three hundred sixty subjects (mean age +/- standard deviation = 81.5 +/- 6.4) admitted from home to a geriatric hospital and showing functional decline, especially in mobility. INTERVENTION: The participants were randomly assigned to receive a comprehensive geriatric assessment followed by a diagnostic home visit and home intervention or a comprehensive geriatric assessment with recommendations and usual care at home. The home intervention included a diagnostic home visit, assessing the home for environmental hazards, advice about possible changes, offer of facilities for any necessary home modifications, and training in the use of technical and mobility aids. An additional home visit was made after 3 months to reinforce the recommendations. After 12 months of follow-up, a home visit was made to all study participants. MEASUREMENTS: Number of falls, type of recommended home modifications, and compliance with recommendations. RESULTS: After 1 year, there were 163 falls in the intervention group and 204 falls in the control group. The intervention group had 31% fewer falls than the control group (incidence rate ratio (IRR) = 0.69, 95% confidence interval (CI) = 0.51-0.97). The intervention was most effective in a subgroup of participants who reported having had two or more falls during the year before recruitment into the study. In this subgroup, the proportion of frequent fallers and the rate of falls was significantly reduced for the intervention group compared with the control group (21 vs 36 subjects with recurrent falls, P =.009; IRR = 0.63, 95% CI = 0.43-0.94). The compliance rate varied with the type of change recommended from 83% to 33% after 12 months of follow-up. CONCLUSION: Home intervention based on home visits to assess the home for environmental hazards, providing information about possible changes, facilitating any necessary modifications, and training in the use of technical and mobility aids was effective in a selected group of frail older subjects with a history of recurrent falling.

Effectiveness of a multifaceted intervention on falls in nursing home residents.

OBJECTIVES: To evaluate the effectiveness of a multifaceted, nonpharmaceutical intervention on incidence of falls and fallers. DESIGN: Prospective, cluster-randomized, controlled 12-month trial. SETTING: Six community nursing homes in Germany. PARTICIPANTS: Long-stay residents (n = 981) aged 60 and older; mean age 85; 79% female. INTERVENTIONS: Staff and resident education on fall prevention, advice on environmental adaptations, progressive balance and resistance training, and hip protectors. MEASUREMENTS: Falls, fallers, and fractures. RESULTS: The incidence density rate of falls per 1,000 resident years (RY) was 2,558 for the control group (CG) and 1,399 for the intervention group (IG) (relative risk (RR) = 0.55, 95% confidence interval (CI) = 0.41-0.73). Two hundred forty-seven (52.3%) fallers were detected in the CG and 188 (36.9%) in the IG (RR = 0.75, 95% CI = 0.57-0.98). The incidence density rate of frequent fallers (>2/year) was 115 (24.4%) for the CG and 66 (13.0%) for the IG (RR = 0.56, 95% CI = 0.35-0.89). The incidence density rate of hip fractures per 1,000 RY was 39 for the CG and 43 for the IG (RR = 1.11, 95% CI = 0.49-2.51). Other fractures were diagnosed with an incidence density rate of 52 per 1,000 RY for CG and 41 per 1,000 RY for IG (RR = 0.78, 95% CI = 0.57-1.07). CONCLUSION: The incidence density rate of falls and fallers differed considerably between the control and intervention groups. The study was underpowered to demonstrate a significant difference of hip or nonhip fractures. Because of a low fracture rate in both groups, the investigation of fracture rates would have required a larger sample size to detect an effect of the intervention.
