Incidence of and risk factors for medical complications during stroke rehabilitation.
(73/2115)
BACKGROUND AND PURPOSE: The aims of this study were to examine the frequency, types, and clinical factors associated with medical complications that occur during inpatient rehabilitation and to identify risk factors for complications that require a transfer to an acute care facility. METHODS: A cohort of 1029 patients consecutively admitted for inpatient stroke rehabilitation was studied. Demographic and stroke information, impairment, preexisting medical conditions, and admission laboratory abnormalities were recorded. Medical complications, defined as new or exacerbated medical problems, were documented for each patient. Complications that required transfer off rehabilitation were noted. Univariate and multiple logistic regression analyses were used to determine factors that were associated with risk of medical complications and risk of transfer off rehabilitation. RESULTS: Seventy-five percent of patients experienced >/=1 medical complication during rehabilitation. Significant factors for the development of any medical complication included greater neurological deficit (odds ratio [OR], 4.10; confidence interval [CI], 1.88 to 8.91), hypoalbuminemia (OR, 1.71; 95% CI, 1.15 to 2.52), and history of hypertension (OR, 1.81; 95% CI, 1.27 to 2.59). Nineteen percent of patients had a medical complication that required transfer to an acute care facility. Significant factors for transfers were elevated admission white blood cell counts (OR, 1.92; 95% CI, 1.32 to 2.79), low admission hemoglobin levels (OR, 1.89; 95% CI, 1.32 to 2.68), greater neurological deficit (OR, 2.46; 95% CI, 1.37 to 4.39), and a history of cardiac arrhythmia (OR, 1.79; 95% CI, 1.18 to 2.67). CONCLUSIONS: Medical complications are common among patients undergoing stroke rehabilitation. A significant number of these medical complications may require a transfer to an acute facility. (+info)
Falls and confidence related quality of life outcome measures in an older British cohort.
(74/2115)
Falls are common in older subjects and result in loss of confidence and independence. The Falls Efficacy Scale (FES) and the Activities-specific Balance Confidence scale (ABC) were developed in North America to quantify these entities, but contain idiom unfamiliar to an older British population. Neither has been validated in the UK. The FES and the ABC were modified for use within British culture and the internal consistency and test-retest reliability of the modified scales (FES-UK and ABC-UK) assessed. A total of 193 consecutive, ambulant, new, and return patients (n=119; 62%) and their friends and relatives ("visitors", n=74; 38%) were tested on both scales, while the last 60 subjects were retested within one week. Internal reliability was excellent for both scales (Cronbach's alpha 0.97 (FES-UK), and 0.98 (ABC-UK)). Test-retest reliability was good for both scales, though superior for the ABC-UK (intraclass correlation coefficient 0.58 (FES-UK), 0.89 (ABC-UK)). There was evidence to suggest that the ABC-UK was better than the FES-UK at distinguishing between older patients and younger patients ([t(ABC)] = 4.4; [t(FES)] = 2.3); and between fallers and non-fallers ([t(ABC)] = 8.7; [t(FES)] = 5.0) where the t statistics are based on the comparison of two independent samples. The ABC-UK and FES-UK are both reliable and valid measures for the assessment of falls and balance related confidence in older adults. However, better test-retest reliability and more robust differentiation of subgroups in whom falls related quality of life would be expected to be different make the ABC-UK the current instrument of choice in assessing this entity in older British subjects.

Use of psychoactive drugs and related falls among older people living in a community in Brazil.
(75/2115)
INTRODUCTION: Population aging in Brazil has increased the prevalence of neurodegenerative diseases (Parkinson's and Alzheimer's disease) and affective disorders (anxiety, depression), all common in old age. A retrospective study was carried out with the purpose of ascertaining if there is an association between falls and psychoactive medication use among older residents of a community in Brazil. METHODS: All residents aged 65+ (n=161) of one neighborhood of Campo Belo, Brazil (population of 48,000) were evaluated regarding the use of psychoactive drugs and the occurrence of falls in the 12 months preceding the study. Vision and hearing screenings were also performed. RESULTS: From the study population, 9.3% were taking prolonged half-life benzodiazepines, 4.4% anticonvulsants (mostly barbiturates), 2.5% antidepressants (all cyclics) and 8.1% alpha-methyldopa. No subject reported use of hypnotics, neuroleptics or drugs to treat Alzheimer's or Parkinson's diseases (except biperiden). As a whole, drugs that increase the risk of falls were used by 1/5 of this population. In the 12-month period preceding the study, 27 residents (16.8%) experienced falls and, of those, 4 (14.8%) had fracture(s). There was an independent association between psychoactive drug use and falls when variables such as age, gender, vision and hearing were controlled (p=0.02). CONCLUSIONS: Although the population of this neighborhood must be considered young (only 4% are 65 years old or more), there are already problems related to the use of psychoactive drugs among people. Prescribed anxiolytics, anticonvulsants, antidepressants and antihypertensives are not appropriate for this age group and their use is associated with falls. (+info)
Comorbidities associated with overactive bladder.
(76/2115)
Overactive bladder (OAB), defined as symptoms of frequency, urgency, and urge incontinence, that occur singly or in any combination in the absence of local pathologic or metabolic factors, is a highly prevalent disorder with an unknown etiology. Few risk factors for OAB have been elucidated through epidemiologic studies, and even less is known about the contribution of OAB to other morbidities. An overview is provided of the impact of OAB on other problems now known to coexist with OAB including falls and fractures, urinary tract and skin infections, sleep disturbances, and depression.

SAFE PACE 2: Syncope and Falls in the Elderly--Pacing and Carotid Sinus Evaluation: a randomized controlled trial of cardiac pacing in older patients with falls and carotid sinus hypersensitivity.
(77/2115)
SAFE PACE is a multicentre randomized controlled trial to assess the efficacy of dual-chamber pacing in older patients with carotid sinus hypersensitivity and recurrent unexplained falls. Patients are eligible if they have had two or more unexplained falls (+/- up to one syncope) and if they have a cardio-inhibitory response (>3 s asystole) to carotid sinus massage. Patients will be randomized to receive either a Medtronic Kappa 700(Europe)/Kappa 400(North America) pacemaker or an implantable loop recorder (ILR)(control group). Patients will be required to complete weekly fall diaries. The primary outcome measure is the number of patients who fall in the 24-month follow-up period. Recruitment began in October 1998 and continues for 12 months; the follow-up is for 24 months. (+info)
Risk factors for proximal humerus, forearm, and wrist fractures in elderly men and women: the Dubbo Osteoporosis Epidemiology Study.
(78/2115)
Fractures of the proximal humerus, forearm, and wrist account for approximately one third of total osteoporotic fractures in the elderly. Several risk factors for these fractures were evaluated in this prospective study of 739 men and 1,105 women aged > or =60 years in Dubbo, Australia. During follow-up (1989-1996), the respective incidences of humerus and of forearm and wrist fractures, per 10,000 person-years, were 22.6 and 33.8 for men and 54.8 and 124.6 for women. Independent predictors of humerus fracture were femoral neck bone mineral density (FNBMD) (relative risk (RR) = 2.3, 95% confidence interval (CI): 1.2, 4.5) in men and FNBMD (RR = 2.4, 95% CI: 1.7, 3.5) and height loss (RR = 1.1, 95% CI: 1.0, 1.2) in women. For forearm and wrist fractures, risk factors were FNBMD (men: RR = 1.5, 95% CI: 1.0, 2.3; women: RR = 1.5, 95% CI: 1.2, 1.9) and height loss (men: RR = 1.2, 95% CI: 1.0, 1.3; women: RR = 1.1, 95% CI: 1.0, 1.2). In addition, dietary calcium (men: RR = 2.0, 95% CI: 1.0, 3.6) and a history of falls (women: RR = 1.9, 95% CI: 1.4, 2.6) were also significant. These data suggest that elderly men and women largely share common risk factors for upper limb fractures and that FNBMD is the primary risk factor. (+info)
Effectiveness and economic evaluation of a nurse delivered home exercise programme to prevent falls. 1: Randomised controlled trial.
(79/2115)
OBJECTIVES: To assess the effectiveness of a trained district nurse individually prescribing a home based exercise programme to reduce falls and injuries in elderly people and to estimate the cost effectiveness of the programme. DESIGN: Randomised controlled trial with one year's follow up. SETTING: Community health service at a New Zealand hospital. PARTICIPANTS: 240 women and men aged 75 years and older. INTERVENTION: 121 participants received the exercise programme (exercise group) and 119 received usual care (control group); 90% (211 of 233) completed the trial. MAIN OUTCOME MEASURES: Number of falls, number of injuries resulting from falls, costs of implementing the programme, and hospital costs as a result of falls. RESULTS: Falls were reduced by 46% (incidence rate ratio 0.54, 95% confidence interval 0.32 to 0.90). Five hospital admissions were due to injuries caused by falls in the control group and none in the exercise group. The programme cost $NZ1803 (523 pound sterling) (at 1998 prices) per fall prevented for delivering the programme and $NZ155 per fall prevented when hospital costs averted were considered. CONCLUSION: A home exercise programme, previously shown to be successful when delivered by a physiotherapist, was also effective in reducing falls when delivered by a trained nurse from within a home health service. Serious injuries and hospital admissions due to falls were also reduced. The programme was cost effective in participants aged 80 years and older compared with younger participants. (+info)
Effectiveness and economic evaluation of a nurse delivered home exercise programme to prevent falls. 2: Controlled trial in multiple centres.
(80/2115)
OBJECTIVES: To assess the effectiveness of trained nurses based in general practices individually prescribing a home exercise programme to reduce falls and injuries in elderly people and to estimate the cost effectiveness of the programme. DESIGN: Controlled trial with one year's follow up. SETTING: 32 general practices in seven southern New Zealand centres. PARTICIPANTS: 450 women and men aged 80 years and older. INTERVENTION: 330 participants received the exercise programme (exercise centres) and 120 received usual care (control centres); 87% (371 of 426) completed the trial. MAIN OUTCOME MEASURES: Number of falls, number of injuries resulting from falls, costs of implementing the programme, and hospital costs as a result of falls. RESULTS: Falls were reduced by 30% in the exercise centres (incidence rate ratio 0.70, 95% confidence interval 0.59 to 0.84). The programme was equally effective in men and women. The programme cost $NZ418 (121 pound sterling) (at 1998 prices) per person to deliver for one year or $NZ1519 (441 pound sterling) per fall prevented. Fewer participants had falls resulting in injuries, but there was no difference in the number who had serious injuries and no difference in hospital costs resulting from falls in exercise centres compared with control centres. CONCLUSIONS: An individually tailored exercise programme, delivered by trained nurses from within general practices, was effective in reducing falls in three different centres. This strategy should be combined with other successful interventions to form part of home programmes to prevent falls in elderly people. (+info)
