BACKGROUND AND PURPOSE Stroke is a leading cause of disability. Rehabilitation robotics have been developed to aid in recovery after a stroke. This study determined the additional cost of robot-assisted therapy and tested its cost-effectiveness. METHODS We estimated the intervention costs and tracked participants' healthcare costs. We collected quality of(More)
BACKGROUND AND PURPOSE Quality of care delivered in the inpatient and ambulatory settings may be correlated within an integrated health system such as the Veterans Health Administration. We examined the correlation between stroke care quality at hospital discharge and within 6 months postdischarge. METHODS We conducted a cross-sectional hospital-level(More)
BACKGROUND Chronic upper extremity impairment due to stroke has significant medical, psychosocial, and financial consequences, but few studies have examined the effectiveness of rehabilitation therapy during the chronic stroke period. OBJECTIVE . To test the safety and efficacy of the MIT-Manus robotic device for chronic upper extremity impairment(More)
AIMS We derived and validated a clinical prediction rule that can be used to predict post-stroke pneumonia. METHODS We conducted a retrospective cohort study of patients admitted to hospital with a stroke. The cohort was subdivided into a derivation group and a validation group. Within the derivation group, a point scoring system was developed to predict(More)
BACKGROUND Clinicians need self-directed learning skills to maintain competency. The objective of this study was to develop and implement a curriculum to teach physicians self-directed learning skills during inpatient ward rotations. METHODS Residents and attendings from an internal medicine residency were assigned to intervention or control groups;(More)
BACKGROUND Prior research has indicated an association between insulin resistance and stroke; we sought to determine if this association persists after adjusting for stroke risk factors, including glycemic control. METHODS We used data from the Third National Health and Nutrition Survey (1988-1994), including participants aged > or =40 years. We assessed(More)
BACKGROUND The treatment of hypertension is an essential component of stroke prevention; however, the clinical management of patients with cerebrovascular disease is complicated by orthostatic hypotension (OH). The primary objectives were to: determine the prevalence of OH in a stroke outpatient clinic; describe categories of OH; and identify factors(More)
OBJECTIVE There is concern that do-not-resuscitate (DNR) orders may lead to stroke patients receiving less aggressive treatment and poorer care. Our objectives were to assess the relationship between DNR orders and quality of stroke care among veterans. METHODS A cohort of 3,965 acute ischemic stroke patients admitted to 131 Veterans Health Administration(More)
BACKGROUND Falls are common after stroke. Simple, clinically practical tools are needed to easily identify patients with stroke who are at risk of falls. The objective of this study was to identify the factors associated with increased fall risk in a poststroke population. METHODS We assessed factors associated with fall risk among poststroke patients.(More)
This study assessed the positive and negative predictive values and the sensitivity and specificity of a nursing dysphagia screening tool and the National Institutes of Health Stroke Scale (NIHSS) for the identification of dysphagia for veterans hospitalized with ischemic stroke.A secondary objective of this study was to evaluate the speech-language(More)
